PART I

Item 1. BUSINESS

The Company

Accuray Incorporated is a radiation therapy company that develops, manufactures, sells and supports market-changing solutions that are designed to deliver radiation treatments for even the most complex cases, while making commonly treatable cases even more straightforward, to meet the full spectrum of patient needs. We believe in comparison to conventional linear accelerators, our treatment delivery, planning, and data management solutions provide better accuracy, flexibility, and control; fewer treatments with shorter treatment times; and the technology to expand beyond cancer, making it easier for clinical teams around the world to provide treatments that help patients get back to living their lives, faster.

Our solutions are designed to advance patient care: during each individual treatment, throughout the treatment process, and at each stage of the cancer treatment journey, from curative to palliative treatments. Our solutions include:

Our innovative technologies, the CyberKnife and TomoTherapy platforms, including the Radixact System, our next generation TomoTherapy platform, are designed to deliver advanced treatments, including stereotactic radiosurgery (“SRS”), stereotactic body radiation therapy (“SBRT”), intensity modulated radiation therapy (“IMRT”), image-guided radiation therapy (“IGRT”), and adaptive radiation therapy (“ART”). The CyberKnife and TomoTherapy platforms have complementary clinical applications with the same goal: to empower our customers to deliver the most precise and accurate treatments while still minimizing dose to healthy tissue, helping to reduce the risk of side effects that may impact patients’ quality of life. Each of these systems serve patient populations treated by the same medical specialty, radiation oncology, with advanced capabilities. The CyberKnife platform is also used by neurosurgeons specializing in radiosurgery to treat patients with tumors in the brain and spine, and neurologic and/or endocrine disorders. In addition to these products, we also provide services, which include post-contract customer support (warranty period services and post-warranty services), installation services, training, and other professional services.

We were incorporated in California in 1990 and commenced operations in 1992. We reincorporated in Delaware in 2007. Our principal offices in the United States are located in Madison, Wisconsin and Santa Clara, California.

Our Strategy

Our goal is to develop equipment and technology that enable physicians to deliver precise and accurate, customized, leading‑edge treatments that help patients with cancerous or benign tumors, or neurologic or endocrine disorders, get back to living their lives, faster. We endeavor to achieve this goal by expanding the clinical options for healthcare providers, helping

them offer the best radiation treatment for each patient tailored to their specific needs. Our vision is to expand the curative power of radiation therapy to improve as many lives as possible. We believe our current technologies and our future innovations can help to achieve this. Some of the key elements of our strategy include the following:

Increase physician adoption and patient awareness to drive utilization. We are continually working to increase adoption and awareness of our systems and demonstrate their advantages over other treatment methods, including more conventional approaches. We hold and sponsor symposia and educational meetings and support clinical studies to demonstrate the clinical benefits of our systems. We regularly meet with clinicians to educate them on the expanded versatility that our systems offer in comparison to more traditional radiation therapy products or surgery. We are continuously expanding our digital and social presence to reach and educate a broader audience of physicians and patients. To support awareness of all our product offerings, we assist our customers with increasing patient awareness in their communities by providing them with tools to develop marketing and educational campaigns.

Continue to expand the radiosurgery market. The CyberKnife System is a robotic radiosurgery system capable of treating tumors throughout the body. There is an extensive body of published literature supporting the use of the CyberKnife System in the treatment of various targets, including cancers, benign tumors, or functional diseases. Radiosurgery is a commonly used procedure among neurosurgeons, specializing in radiosurgery, who require the high level of precision found with surgery, yet want to offer their brain tumor patients a non-invasive option. With more than 30 years of clinical evidence, the CyberKnife System offers distinct advantages in the treatment of diseases in the head, base of the skull, and spine. These areas of the body require extremely accurate treatment because of the proximity of the tumors to critical radiosensitive structures that may impact a person’s ability to perform basic functions and to think, see, hear, walk and breathe.

Continue to innovate through clinical development and collaboration. The clinical success of our products is largely the result of the collaborative partnerships we have developed over the last decade with clinicians, researchers and patients. We proactively seek out and rely on constructive feedback from system users to learn what is needed to enhance the technology. As a result of this collaborative process, we continually refine and upgrade our systems, thereby improving our competitive position in the radiation therapy and radiosurgery markets. Upgrades to our systems are designed to address customer needs in the areas of improving the ease of use and accuracy of treatment, decreasing treatment times, and improving utilization for specific types of tumors.

Expand sales in international markets. We intend to continue to increase our sales and distribution capabilities outside of the United States to take advantage of the large international opportunity for our products. Outside of the United States, we currently have regional offices in Morges, Switzerland, Hong Kong, China, Shanghai, China and Tokyo, Japan and direct sales staff in most countries in Western Europe, Japan, India and Canada, combined with distributors in Europe, Russia, the Middle East, Africa, the Asia Pacific region, and Latin America. Many of the countries in these regions are not highly developed at this time and therefore sales opportunities may be limited. We intend to increase our international revenue by focused additions of direct sales personnel in targeted areas to further penetrate our most promising international markets, and additional distributors, strategic partnerships, or joint ventures where opportune. In addition, we recently introduced Accuray Helix, a CT-guided helical radiotherapy system, to help address gaps in patient access to radiation medicine. The Helix system combines affordability with automation and tools for enhancing the speed of planning and delivery of radiation.

Strategic partnerships and joint ventures. We intend to pursue strategic partnerships and joint ventures we believe will allow us to complement our growth strategy, increase sales in our current markets and expand into adjacent markets, broaden our technology and intellectual property, and strengthen our relationships with our customers.

Our Products

From oncology to radiosurgery and beyond, our solutions enable clinicians to deliver shorter, more personalized, and more effective treatments. Our suite of radiation delivery devices includes the CyberKnife System and our next generation TomoTherapy platform-based solutions, including the Radixact System. In addition, our portfolio includes comprehensive software solutions to enable and enhance the precise and efficient radiotherapy treatments with our advanced delivery systems.

Robotic Radiation Delivery Solutions

The CyberKnife platform is the only robotic, full-body SRS and SBRT delivery device on the market. The latest generation is the CyberKnife S7 System, which combines speed, advanced precision, and real-time AI-driven motion tracking and synchronized treatment delivery for all SRS and SBRT treatments, in as little as 15 minutes. The platform is designed to treat cancerous and benign tumors throughout the body, as well as neurologic and endocrine disorders. The use of SRS and SBRT with the CyberKnife platform to treat tumors throughout the body has grown significantly in recent years. SRS and SBRT are performed on an outpatient basis in a limited number of treatment sessions - typically 1-5 fractions. They enable the treatment of patients who might not otherwise be treated with radiation, who may not be good candidates for surgery, or who desire a non-surgical treatment option.

The CyberKnife S7 System is available for sale in most major markets globally. The system includes disease-specific tracking and treatment delivery solutions for brain, spine, lung and prostate tumors, improvements in treatment speed as compared to earlier systems, more options to configure the treatment room, and expanded number of nodes leading to more coverage and minimizing the dose to healthy tissue. The CyberKnife S7 System comes in a variety of radiation oncology suited configurations, with the option of fixed collimators plus the Iris Variable Aperture Collimator and/or InCise multi-leaf collimators (“MLC”). With the addition of the InCise MLC, the CyberKnife S7 System is designed to enable the treatment of larger tumors that were previously thought untreatable with radiosurgery and SBRT. The InCise MLC and IMRT planning tools are designed to enable expansion of indications that can be treated with a CyberKnife platform to include many IMRT indications.

In addition, we also offer a specific configuration for the neuro-radiosurgery space. The CyberKnife S7 F System is designed to deliver radiosurgery treatments to central nervous system tumors and lesions with sub-millimeter accuracy. It offers precise, frameless, and non-invasive radiosurgery, with features for real-time correction of positional and anatomical changes, and fixed collimators to shape and direct the radiation beam when treating small targets. The system can deliver plans using the Brainlab Elements software to enhance the target definition for radiosurgery treatments for functional neurological indications such as essential tremor, Parkinson’s, and epilepsy. Brainlab Elements software augments the capabilities of the Accuray Precision® Treatment Planning System for contouring, fusion and correction.

Using our Synchrony real-time target tracking with dynamic delivery technology and computer controlled robotic mobility, the CyberKnife platform is designed to deliver radiation from a wide array of beam angles and autonomously track,

detect and correct for even the slightest tumor and patient movement in real‑time throughout the entire treatment. This design is intended to enable the CyberKnife platform to deliver high‑dose radiation with sub-millimeter precision and accuracy, which minimizes damage to surrounding healthy tissue and eliminates the need for invasive head or body immobilization frames.

The Accuray Precision TPS with the VOLO Optimizer software on the CyberKnife S7 System enables customers to significantly improve operational efficiency by reducing both the time to create high quality treatment plans and the time it takes to deliver patient treatments. The next-generation TPS with the VOLO Optimizer facilitates the development of clinically optimal treatment plans up to an estimated 90 percent faster than before and the delivery of the treatment up to an estimated 50 percent faster than before the availability of this software.

We believe that our robotic delivery systems offer clinicians and patients the following benefits:

The only truly robotic system in the market. The CyberKnife platform features a compact linear accelerator mounted on a highly maneuverable robotic arm that moves around the resting patient while delivering isocentric or non-isocentric, non-coplanar treatment radiation beams from potentially thousands of unique angles, tailoring radiation delivery to minimize the dose to healthy tissue, while maintaining sub-millimeter accuracy and precision even for targets that move during treatment. We believe the CyberKnife platform is the clinical solution to choose when accuracy, flexibility, speed, and patient comfort are essential.

Treatment of inoperable or surgically complex tumors. The CyberKnife platform may be used to target tumors that cannot be easily treated with traditional surgical techniques because of their location, number, size, shape or proximity to vital tissues or organs, or because of the age or health of the patient. The CyberKnife platform’s intelligent robotics enable the precise targeting of a tumor, while at the same time minimizing damage to surrounding healthy tissue.

Treatment of tumors throughout the body. The CyberKnife platform has been cleared by the Food and Drug Administration (“FDA”) to provide treatment planning and image-guided radiation therapy treatment for tumors anywhere in the body where radiation treatment is indicated. By comparison, traditional frame‑based radiosurgery systems are generally limited to treating brain tumors with some using cobalt 60 radioactive material, which decays over time and is difficult and expensive to replace. The CyberKnife platform is being used for the treatment of primary and metastatic tumors outside the brain, including tumors on or near the spine and in the breast, kidney, liver, lung, pancreas and prostate, in addition to tumors in the brain, with the same sub‑millimeter accuracy in every disease site.

Real‑time tracking of tumor movement. The CyberKnife platform is designed to accommodate all forms of patient and tumor motion, even while the treatment is being delivered. With the Accuray-exclusive Synchrony AI-driven tumor tracking with dynamic delivery technology, the CyberKnife platform enables smaller treatment margins around the tumor, minimizing the amount of healthy tissue exposed to high-dose radiation.

Significant patient benefits. The CyberKnife platform is designed to maximize patient comfort. Patients may be treated with the CyberKnife platform on an outpatient basis without anesthesia and without the risks and complications inherent in traditional surgery. Patients do not require substantial pretreatment preparation, and typically there is little to no recovery time or hospital stay associated with CyberKnife platform’s treatments. In addition, the CyberKnife platform eliminates the need for an invasive rigid frame to be screwed into the patient’s skull or affixed to other parts of the body, or gating instruments.

Additional revenue generation through increased patient volumes. We believe clinical use of the CyberKnife platform allows our customers to effectively treat patients where extreme precision and ability to account for motion are important, and patients who otherwise would not have been treated with radiation or who may not have been good candidates for surgery.

Upgradeable modular design. The CyberKnife platform has a modular design that facilitates the implementation of upgrades that often do not require our customers to purchase an entirely new system to gain the benefits of new features. We continue to work to develop and offer new clinical capabilities enhancing ease of use, reducing treatment times, improving accuracy and improving patient access. The main components and options of the CyberKnife platform include compact

X‑band linear accelerator; robotic manipulator arm, real‑time image‑guidance system with continuous target tracking and correction.

Key features of the main components include:

Compact X-band linear accelerator. The CyberKnife S7 System utilizes a compact X-band linear accelerator (linac) mounted on a robotic manipulator arm. The side-coupled-cavity radiofrequency standing wave linac is fitted with a triode electron gun, demountable target, and demountable radiofrequency window.

Robotic manipulator arm. The robotic manipulator arm, with six-degrees-of-freedom range of movement, is designed to move around the patient to position the linac and direct the radiation with an extremely high level of precision and repeatability. The manipulator arm provides what we believe to be a unique method of positioning the linac to deliver doses of radiation from nearly any direction and position, without the limitations inherent in gantry-based systems, creating a non‑isocentric composite dose pattern with a high level of conformance to the shape of each treated tumor. This flexibility enhances the ability to diversify beam trajectories and beam entrance and exit points, helping to minimize risks of radiation damage to healthy cells near the tumor. Furthermore, the rapid response time of the manipulator arm allows tracking of tumors that are prone to movement.

Realtime image guidance system with continuous target tracking and correction. Without the need for clinician intervention or treatment interruption, Synchrony is designed to enable continuous monitoring and correction for patient and tumor movements throughout each treatment as it is being delivered. Our patented image guidance technology correlates low dose, real time treatment X-rays with images previously taken with a CT scan of the tumor and surrounding tissue to direct each beam of radiation with increased precision versus treatments without this real time feedback. This, in turn, enables delivery of a highly conformal, non-isocentric dose of radiation to the tumor, minimizing radiation delivered to surrounding healthy tissue. Synchrony is the only technology that uses AI, through image guidance, to automatically adapt and synchronize the treatment delivery beam position to the target location precisely and accurately during the delivery of a treatment fraction. The beams of radiation are delivered continuously throughout the treatment session as the patient behaves naturally. The Synchrony technology provides what we believe is unsurpassed clinical accuracy for lung tumors that move with respiration without the need for implanted fiducials. It makes it possible and practical for clinicians to deliver radiation dose with sub-millimeter precision and accuracy, even for tumors that are prone to movement.

Imaging sources. The low energy X‑ray sources generate the images that help determine the location of bony or other anatomic landmarks, or implanted fiducials, which are used for tracking throughout the entire treatment.

Imaging detectors. The image detectors capture high resolution anatomical images throughout the treatment. These live images are continually compared to the patient’s CT scan to determine real time patient positioning. Based on this information, the robotic manipulator automatically corrects for detected movements.

In addition to the main components listed above, we also offer the following components and options: Lung Optimized Treatment; Synchrony Fiducial Tracking with the InTempo Imaging System; RoboCouch Patient Positioning System; Xchange Robotic Collimator Changer; Iris Variable Aperture Collimator; and the InCise MLC. Key features of some of these components are as follows:

Synchrony Skull, Spine and Lung Tracking Systems. The Synchrony Skull, Spine and Lung Tracking Systems allow for tracking of tumors without the need for implanted markers in the skull, spine and the lung.

Lung Optimized Treatment. An integrated suite of tools that provides a complete fiducial free clinical solution for lung cancer patients and optimizes noninvasive lung SBRT treatments.

InTempo Imaging System. The InTempo Imaging System with the Synchrony Fiducial Tracking System is designed to optimize imaging frequency during prostate treatments, for example, using time-based image guidance to assist with tracking and correcting non‑predictable intrafraction target motion.

Iris Variable Aperture Collimator. The Iris Variable Aperture Collimator enables delivery of beams in 12 unique sizes with a single collimator, which significantly reduces treatment times and the total radiation dose delivered to the patient.

Fixed Collimators. The Fixed Collimators enables delivery of beams in 12 unique sizes with 12 different collimators, usually used for radiosurgery.

InCise Multileaf Collimator. The InCise MLC is designed to deliver the same precise SRS and SBRT treatments clinicians expect from the CyberKnife platform, while significantly reducing treatment times. With the InCise MLC, the CyberKnife S7 Series can be used to treat larger and irregular tumors more efficiently.

The long-term success of the CyberKnife platform is dependent on a number of factors including the following:

Helical Radiation Delivery Solutions

Through the TomoTherapy platform, we were the first to introduce helical radiation therapy, revolutionizing the way radiation is delivered. Helical radiation therapy is a type of treatment that integrates the linear accelerator and CT imaging technology to deliver radiation from multiple 360-degree rotations around the patient while the patient table moves through center of the system. Helical radiation therapy helps to provide greater control of the radiation dose so it conforms precisely to the tumor and helps minimize dose to healthy tissue.

Since the introduction of the TomoTherapy platform, Accuray has built on its legacy with the introduction of innovative solutions including the Radixact, Accuray Helix and Tomo C Systems, each tailored to meet the evolving needs of global markets.

The Radixact System is the next generation TomoTherapy platform. The system allows for fully integrated radiation treatment planning, delivery and data management, enabling clinicians to deliver ultra-precise treatments to more than 50 patients per day. Additionally, the system offers two treatment delivery modes - TomoHelical™ and TomoDirect™ - providing flexibility in the types of indications that can be treated with radiation - from the simplest to the most complex cases, multiple tumors and recurrent tumors.

Accuray Helix™ combines affordability with automation and tools for enhancing the speed of planning and delivery of radiation. The system is designed to provide a broad range of capabilities to increase flexibility and versatility for facilities that may have resources and staffing for only one system, enabling them to offer state-of-the-art cancer care in their communities.

The new, made in China Tomo® C System, is the first CNNC-Accuray joint venture product. A fast and effective radiation delivery device, the system will enable more medical care teams within China to provide personalized and highly precise treatments to more people each day.

We believe that our helical delivery systems offer clinicians and patients the following benefits:

Versatile treatment capabilities. The ring gantry architecture enables precise and efficient treatments with a high degree of dose conformity. The high‑speed binary MLC is integrated with the linac and consists of 64 individual low leakage tungsten leaves that move across the beam to either block or allow the passage of radiation, effectively modulating and shaping the beam as it is emitted. The combination of the ring gantry and the high‑speed MLC enable treatment to be delivered continuously in a 360‑degree helical pattern around the patient’s body (which we refer to as TomoHelical). Additionally, the TomoDirect feature provides the TomoTherapy platform with added versatility, enabling the delivery of high quality, fixed angle beams for those cases suited to simple fixed angle radiation delivery. All TomoTherapy platform systems enable an operator to provide non‑isocentric 3D conformal radiotherapy (“3D CRT”), IG-IMRT, or stereotactic treatments within a typical cylindrical volume of 40 centimeters in diameter and up to 135 centimeters in length. This expansive treatment field allows single or multiple tumors, located anywhere in body, to be treated in a single session. The TomoTherapy platform’s versatility, efficiency and precision offer clinicians an extensive range of effective treatment possibilities.

Diagnostic-like quality kVCT images enable better visualization of tumors, dose verification and re-planning. We launched ClearRT™ helical kVCT imaging technology for the Radixact System, and have also made this advanced imaging available on the Accuray Helix and Tomo C systems. ClearRT helical kVCT enables high-fidelity imaging, providing clinicians with an option to produce exceptional diagnostic-like quality CT images, quickly and cost-effectively, to improve patient care. ClearRT imaging brings low dose diagnostic-like kVCT imaging quality, the largest imaging field of view available on a radiation delivery system at 50 cm (diameter) by 135 cm (long), and speed, as evidenced by its ability to capture a 1-meter image in only 1 minute. ClearRT delivers enhanced imaging capabilities compared to conventional linear accelerator systems that rely on cone-beam CT (“CBCT”) imaging, and as an alternative to MR-based radiation therapy systems that can be complex and cost prohibitive to use. ClearRT offers excellent uniformity and low noise across the entire image, improved soft tissue visualization while maintaining exceptional spatial resolution, which is intended to enhance the versatility and efficiency of the Radixact System in the radiation therapy department. ClearRT helical kVCT images are also available within the Accuray PreciseART® automated dose trending tool for clinicians to evaluate if plan adaptation would be beneficial, enabling the most personalized patient care.

Integrated treatment system for precise radiation delivery. We believe the integration of our proprietary imaging technology, treatment planning and helical radiation delivery mode enables highly accurate and precise radiation therapy. Our planning software allows clinicians to establish the contours of a tumor and any normal radio-sensitive structures in close proximity to the treatment beam. The TomoTherapy platform uses an intelligent dose optimization algorithm to ensure the radiation beam conforms to the patient’s tumor and minimizes exposure to surrounding healthy tissue structures, providing a highly targeted and effective dose distribution. These features significantly benefit patients by increasing the radiation delivered to cancerous tissues, while minimizing damage to nearby healthy tissues, thus also minimizing side effects.

Enhancing efficiency and quality of treatment planning and delivery. We are committed to providing clinical teams with technologies that improve both the efficiency and quality of radiation therapy planning. Our goal is to streamline workflows while maintaining the precision and consistency essential to modern oncology. VOLO™ Ultra, our next-generation optimization engine, supports this by dramatically accelerating treatment planning without compromising accuracy—enabling faster plan generation, improved throughput, and greater support for adaptive and personalized radiotherapy.

Efficient clinical workflow for Image-Guided Radiation Therapy and adaptive radiation therapy. The TomoTherapy platform integrates into a single system all of the key elements for radiation therapy, including treatment planning, CT image-guided patient positioning, treatment delivery, quality assurance and adaptive planning. The imaging and treatment planning capabilities of many traditional systems are more modular or require cumbersome add‑ons or separate treatment planning systems that result in clinicians taking more steps between scanning, planning and treatment of patients. Conversely, the integrated imaging and treatment features allow clinicians to scan, plan and treat cancer patients efficiently. Treatment plans as well as daily images can be easily accessed remotely, enabling clinical teams to collaboratively work together, regardless of location, ensuring higher quality plan development and delivery.

Low barriers to installation and implementation. All external beam radiation systems must be housed in rooms that have special radiation shielding to capture any radiation not absorbed by the patient. The TomoTherapy platform’s size and self‑contained design allow customers to retrofit them into existing treatment rooms previously used for legacy radiation therapy systems and avoid, or reduce, the significant construction costs that can be associated with building new, larger

treatment rooms, which are often required of other radiation therapy systems. With both imaging and radiation delivery capabilities integrated on a ring gantry, the systems require less space than other linac systems, which use large moving arms to position the linac or incorporate adjacent imaging equipment used for treatment planning. In addition, because the Radixact System has an integrated radiation beam stop, which shields radiation that passes through the patient, they require less radiation shielding in treatment room walls as compared to traditional systems. We also preassemble, test and commission each system at our manufacturing facility, and ship the system almost fully assembled. This process typically allows radiation “beam on” within four days after delivery and first patient treatments to begin within 14 to 28 days after delivery.

Enhance precision and reduce treatment time. TomoEDGE Delivery. TomoEDGE dynamically varies the width of the collimator jaws during treatment delivery, dose to normal healthy tissues immediately adjacent to the tumor is reduced, helping to minimize the risk of radiation side effects. Additionally, overall treatment time is shortened because the jaws opening can be effectively tailored to the size of the tumor, enabling more efficient dose coverage. The resulting gains in treatment quality and speed expand the Radixact Systems’ clinical and market reach within the conventional and stereotactic radiotherapy spaces.

Platform for further technological advancements in adaptive radiation therapy. We believe the helical delivery systems are uniquely positioned to enable truly adaptive radiation therapy because of their ability to provide daily, quantitative images, high speed delivery of radiation from fixed beam angles or helically from 360 degrees around the body and real time verification of the dose received by the patient. We believe the combination of these design features and our integrated treatment planning and optimization software will allow us to continue to enhance our systems adaptive capabilities to enable clinicians to routinely and easily adjust a patient’s treatment as needed, thereby remaining true to the intent of the original treatment plan.

In addition to the functionality listed above, the Radixact System may be enhanced with the following product options:

Real-time tracking of tumor movement. The Accuray proprietary Synchrony® AI-driven real-time target tracking with dynamic delivery technology is a collection of unique hardware and software technologies that enables personalized real-time adaptive delivery of radiation treatment to targets while they are in motion by synchronizing the treatment delivery beam position to the target location precisely and accurately during the delivery of a treatment fraction. Synchrony is the only technology that uses AI, through image guidance, to automatically adapt and synchronize the radiation beam to the position of the tumor if and when it moves during treatment. The beams of radiation are delivered continuously throughout the treatment session as the patient behaves naturally. Synchrony can be used on the Radixact System to adapt treatment delivery for tumors that move as a result of bodily processes, including respiration and digestion, as well as patient movement. Synchrony treatments are truly personalized, as delivery is adapted to the individual’s unique movements throughout treatment delivery. If movement changes during treatment, delivery is adapted for that unique change. The Synchrony technology makes it possible and practical for clinicians to deliver radiation dose with accuracy and precision, even for tumors that move. Synchrony helps to maximize treatment effectiveness and minimize dose to surrounding healthy tissue because it accounts for the current and changing conditions of the patient during treatment delivery.

The VitalHold Solution enables medical care teams to treat patients with SGRT using the Radixact System. SGRT helps to effectively position the patient and monitor the accuracy of that positioning throughout their treatment, enhancing precision in radiation delivery. VitalHold also enables DIBH treatments on the Radixact System. During DIBH treatments, a patient takes a deep breath which moves the heart away from the chest wall and the targeted tumor to help minimize radiation dose to organs at risk (“OARs”) and reduce associated complications later in life.

We believe the TomoTherapy platform offers clinicians and patients significant benefits over other vendors’ radiation therapy systems in the market. The long-term success of the TomoTherapy platform is dependent on a number of factors, including the following:

Our Accuray Precision TPS with iDMS Data Management Systems provide fully integrated treatment planning and data management for use with all compatible Accuray delivery platforms.

Accuray Precision Treatment Planning. With a streamlined and intuitive interface, Accuray Precision TPS enables clinicians to efficiently generate high quality radiation therapy treatment plans for all case types. It is a complete planning solution, including multi‑modality image fusion with proprietary deformable image registration algorithm, comprehensive suite of contouring tools, AutoSegmentation and auto contouring options for head and neck, brain, and prostate, side-by-side treatment plan comparison, plan summation and evaluation. It supports treatment plan creation for all case types with TomoHelical, TomoDirect IMRT and 3D CRT planning mode on both Radixact and TomoTherapy Systems enabled with iDMS Data Management Systems. It also supports planning for all case types on CyberKnife platforms, including Frameless Intracranial Radiosurgery, Fiducial Free Lung Tracking with Dynamic Motion Synchronization, SBRT, for the skull, spine, abdomen and pelvis, as well as IMRT. It provides fast and accurate dose computation engines for both Accuray platforms, including Monte Carlo dose calculation for the CyberKnife InCise Multileaf Collimator and VOLO™ Technology for the CyberKnife, Radixact and TomoTherapy Systems. The VOLO and VOLO Ultra solutions feature high-speed processing for both dose calculation and optimization that empowers clinicians to create highly customized treatment plans in less time, with greater flexibility to work interactively and in real time to efficiently develop the best IMRT treatment plans for even the most complex cases.

The Accuray Precision TPS can be further enhanced with optional advanced capabilities described below:

PreciseART Adaptive Radiation Therapy Option. The PreciseART Radiation Therapy Option extends adaptive radiotherapy possibilities, delivering an entirely new level of system integration and workflow automation for Radixact and other TomoTherapy Systems compatible with iDMS. The PreciseART Option enables clinicians to monitor patient treatment and efficiently adapt plans, helping clinics of all sizes deliver more precise treatments to more patients. It offers automated processing of daily imaging to enable clinicians to monitor all patients and set protocol specific action levels to flag cases for review and possible plan adaptation. The PreciseART software's streamlined re‑planning capabilities leverage full integration of treatment delivery, planning and database systems to allow clinicians to efficiently generate new treatment plans based on previous plan data. It is also designed to maintain the integrity of original treatment plans to ensure tumor coverage, preserve OAR doses and reduce toxicity.

PreciseRTX Retreatment Option. The PreciseRTX Retreatment Option makes retreatment planning more efficient and effective. The option helps to accelerate and enhance the process of creating new treatment plans for patients who have received previous irradiation. The workflow includes importation of patient dose data, from either Accuray or non-Accuray planning systems, automatic deformation of original plan contours onto a new treatment planning CT, automatic deformation of previously delivered dose onto a new planning CT, generation of the re-treatment plan based on the information from the existing plan and summation of the original and new treatment plans to review the total dose.

Accuray iDMS Data Management System. Accuray iDMS creates a centralized platform for storing and managing all patient treatment plan data. Designed to integrate with a wide range of technologies and systems, iDMS enables users and applications to securely and seamlessly access the data they need to drive efficient, informed, effective treatment. Information for patients to be treated or previously treated on any iDMS compatible Accuray platforms will be maintained as a single treatment record, providing the flexibility to treat patients on any available Accuray platform compatible with iDMS. It can manage users and privileges to control patient data access. It supports the Storage Vault option, which can safely maintain years of encrypted patient data. It also offers customizable report generation of patient, plan and treatment system with Report Administration Application. In addition, the Accuray iDMS enables connectivity between Accuray platforms with other systems in radiation oncology departments, encompassing the entire radiotherapy workflow. iDMS offers several key capabilities:

OIS Connect Option. The OIS Connect software option is a Digital Imaging and Communications in Medicine (“DICOM”) standard-based solution that provides the ability to interface all iDMS enabled Accuray platforms to compatible OISs. This integration with electronic medical record generates a comprehensive export of the radiotherapy treatment history delivered using Accuray platforms.

Total Quality Assurance (TQA™) package. The TQA application offers trending and reporting of many systems and dosimetric parameters that allow physicians to monitor the performance of their TomoTherapy platforms.

Delivery Analysis™. Delivery Analysis is an option for the TomoTherapy platform that enables easy pretreatment quality assurance. The software also offers an innovative capability to monitor doses throughout the patient treatment using detector signals to ensure that the patient is receiving the expected dose from treatment to treatment. Delivery Analysis provides both high level analytics for summary display as well as detailed analysis capability.

Sales and Marketing

In the United States, we primarily market directly to customers, including hospitals and stand-alone treatment facilities, through our sales organization, and we also market to customers through sales agents and group purchasing organizations. Outside the United States, we market to customers directly and through the use of distributors and sales agents. We currently have international offices in Morges, Switzerland; Hong Kong, China; Shanghai, China and Tokyo, Japan and direct sales staff in most countries in Western Europe, Japan, India and Canada. In addition, we have distributors in Europe, Russia, the Middle East, Africa, the Asia Pacific region, and Latin America.

In direct sales markets, we employ a combination of territory sales managers, product specialists, training specialists and marketing managers. Territory sales managers and product specialists are responsible for selling the systems to hospitals and stand‑alone treatment facilities. Our marketing managers help market our current products and work with our engineering group to identify and develop upgrades and enhancements for our suite of products. Our training specialists train radiation oncologists, surgeons, physicists, dosimetrists and radiation therapists.

We market our products to radiation oncologists, neurosurgeons, general surgeons, oncology specialists and other referring physicians in hospitals and stand‑alone treatment facilities. We intend to continue to increase our focus on marketing and education efforts to surgical specialists and oncologists responsible for treating tumors throughout the body and are also working closely with hospital administrators to demonstrate the economic benefits of our offering. Our marketing activities also include efforts to inform and educate patients with cancerous or benign tumors, or neurologic and/or endocrine disorders, about the benefits of the CyberKnife and TomoTherapy robotic and helical platforms.

Under our standard distribution agreement, we generally appoint a distributor for a specific country. We typically also retain the right to distribute our full portfolio of solutions in such territories. In most territories, our distributors generally provide the full range of service and sales capabilities, although we may provide installation and service support for certain distributors.

The JV aims to be uniquely positioned to serve China, which we believe is the world’s largest growth market for radiation oncology systems. China represents a significantly underserved market for linacs based on the country’s population and cancer incidence rates on both an absolute and relative country basis. Accuray Asia has a 49% ownership interest in the JV and the CIRC Subsidiary has a 51% ownership interest in the JV.

With the receipt of the necessary permits and licenses to operate, the JV has begun selling products in China, much like a distributor. The JV has recently begun to manufacture and sell a locally branded “Made in China” radiotherapy device, or the Tomo® C radiation therapy system, in the Class B license category. We believe this strategy will allow us to best maximize both near and longer-term opportunities in China. In September 2023, we received approval for our Class B device from the National Medical Products Administration (“NMPA”) and our Accuray Precision Treatment Planning System for the Class B device was approved by the NMPA in June 2024. The JV also distributes other Accuray treatment delivery systems like the Radixact and CyberKnife treatment delivery systems, including the Radixact SynC and CyberKnife S7 Systems, which received NMPA approval in January 2025.

For more information on the JV, see Note 11, “Joint Venture,” of the Notes to the consolidated financial statements.

Manufacturing

We purchase major components for each of our products from outside suppliers, including the robotic manipulator, treatment couches, gantry, magnetrons and computers. We closely monitor supplier quality, delivery performance and conformance to product specifications, and we also expect suppliers to contribute to our efforts to improve our manufacturing cost and quality.

Some of the components are obtained from single‑source suppliers. These components include the couch, magnetron and solid state modulator for the TomoTherapy platform and the robot, couch, and magnetron for the CyberKnife platform. In most cases, if a supplier was unable to deliver these components, we believe we would be able to find other sources for these components subject to any regulatory qualifications, if required. In the event of a disruption in any of these suppliers’ ability to deliver a component, we would need to secure a replacement supplier. Additionally, any disruption or interruption of the supply of key subsystems could result in increased costs and delays in deliveries of our treatment systems, which could adversely affect our reputation and results of operations. To help mitigate these risks, we negotiate long‑term supply contracts or submit long‑term orders and forecasts to our single‑source suppliers with the goal that our demand can be satisfied and any capacity problem can be mitigated.

Currently, we manufacture our CyberKnife and TomoTherapy platforms in Madison, Wisconsin. We manufacture the linear accelerator for our CyberKnife and TomoTherapy platforms at our Chengdu, China facility. Our facilities employ state‑of‑the‑art manufacturing techniques and equipment. Our Madison headquarters manages and oversees the complete design, manufacturing, installation, service and distribution for our medical devices under one global quality management systems compliant to the internationally recognized quality system standard for medical devices ISO, 13485:2016, and the Quality System regulations enforced by the FDA. We believe our manufacturing facilities will be adequate for our expected growth and foreseeable future demands for at least the next three years.

The manufacturing processes at our facilities include fabrication, subassembly, assembly, system integration and final testing. Our manufacturing personnel consist of fabricators, assemblers and technicians supported by production engineers as well as planning and supply chain managers. Our quality assurance program includes various quality control measures from inspection of raw material, purchased parts and assemblies through on‑line inspection. We have also incorporated lean manufacturing techniques to improve manufacturing flow and efficiency. Lean manufacturing techniques include reducing wasteful and extraneous activities, balancing assembly and test flow, as well as better utilizing production assets and resources.

Intellectual Property

The proprietary nature of, and protection for, our products, product components, processes and know‑how are important to our business. We seek patent protection in the United States and internationally for our systems and other technology where available and when appropriate. We may also in‑license the technology, inventions and improvements that we consider important to the development of our business. In addition, we also rely upon trade secrets, know‑how, trademarks, copyright protection, as well as confidentiality agreements with employees, consultants and other third parties, to protect our proprietary rights and to develop and maintain our competitive position.

As of June 30, 2025, we held an exclusive field of use licenses or ownership of 530 U.S. and foreign patents, and 84 U.S. and foreign patent applications. These patents and applications cover various components and techniques incorporated into the CyberKnife and TomoTherapy platforms, or which may be incorporated into new technologies under current development, all of which we believe will allow us to maintain a competitive advantage in the field of radiation therapy systems. We cannot be certain that any patents will be issued from any of our pending patent applications, nor can we be certain that any of our existing patents or any patents that may be granted to us in the future will provide us with protection.

We periodically monitor the activities of our competitors and other third parties with respect to their use of intellectual property.

Research and Development

Continued innovation is critical to our future success. Our current product development activities include projects expanding clinical applications, driving product differentiation, and continually improving the usability, interoperability, reliability, and performance of our products. We continue to seek to develop innovative technologies so that we can improve our products and increase our sales. Some of our product improvements have been discussed above under the heading “Our Products.”

Our research activities strive to enable new product development opportunities by developing new technologies and advancing areas of existing core technology such as next generation linear accelerators, adaptive therapy, patient imaging, motion management, or treatment planning capabilities.

The modular design of our systems support rapid development for new clinical capabilities and performance enhancements by generally allowing each subsystem to evolve within the overall platform design. Access to regular product upgrades protects customer investment in the system, facilitates the rapid adoption of new features and capabilities among existing installed base customers, and drives increasing value in our multiyear service plans. These upgrades will generally consist of software and hardware enhancements designed to increase the ease of use of our systems, improve the speed and accuracy of patient treatment and meet other customer needs.

A key component of our research and development program is our collaboration with research programs at selected hospitals, cancer treatment centers, academic institutions and research institutions worldwide. Our agreements with these third‑party collaborators generally require us to make milestone‑based payments during the course of a particular project and often also require that we make up‑front payments to fund initial activities. Generally, we obtain non‑exclusive worldwide rights to commercialize results from the collaboration with an option to negotiate an exclusive license. For inventions resulting from the collaboration that we own or exclusively license, we generally grant a royalty‑free license for the purpose of continuing the institution’s research and development, and from time to time, we also grant broader licenses. Our research collaboration programs include work on clinical protocols and hardware and software developments. We also work with suppliers to develop new components in order to increase the reliability and performance of our products and seek opportunities to acquire or invest in the research of other parties where we believe it is likely to benefit our existing or future products.

We have entered into collaboration agreements with a variety of industrial partners within the fields of radiation oncology and medical imaging to provide us with opportunities to accelerate our innovation capability and bring complimentary products and technologies to market. We continue to seek out new partnerships to complement our internal developments and implement our product strategies.

Competition

The medical device industry in general and the non‑invasive cancer treatment field in particular, are subject to intense and increasing competition and rapidly evolving technologies. Because our products often have long development and regulatory approval cycles, we must anticipate changes in the marketplace and the direction of technological innovation and customer demands. To compete successfully, we will need to continue to demonstrate the advantages of our products and technologies over well established alternative procedures, products and technologies, and convince physicians and other healthcare decision makers of the advantages of our products and technologies. Traditional surgery and other forms of minimally invasive procedures, brachytherapy, chemotherapy, immunotherapy, and other drugs remain alternatives or are complementary to treatments delivered with the CyberKnife and TomoTherapy platforms.

New product sales in this competitive market are primarily dominated by two companies: Varian Medical Systems, Inc, a Siemens Healthineers company (“Varian”) and Elekta AB (“Elekta”). Some manufacturers of standard linac systems, including Varian and Elekta, have products that can be used in combination with body and/or head frame systems and image guidance-systems to perform both radiosurgical and radiotherapy procedures. Our other competitors include RefleXion Medical Inc., ZAP® Surgical Systems, Inc., and other companies in the radiosurgical and radiation therapy markets.

Furthermore, many government, academic and business entities are investing substantial resources in research and development of cancer treatments, including surgical approaches, radiation treatment, MRI-guided radiotherapy systems,

proton therapy systems, drug treatment, immunotherapy, gene therapy, and other approaches. Successful developments that result in new approaches for the treatment of cancer could reduce the attractiveness of our products or render them obsolete.

Our future success will depend in large part on our ability to establish and maintain a competitive position in current and future technologies. Rapid technological development may render the CyberKnife and TomoTherapy platforms and their technologies obsolete. Some of our competitors have or may have greater corporate, financial, operational, sales and marketing resources, and more experience in research and development than we have. We cannot assume that our competitors will not succeed in developing or marketing technologies or products that are more effective or commercially attractive than our products or that would render our technologies and products obsolete or less useful. We may not have the financial resources, technical expertise, marketing, distribution or support capabilities to compete successfully in the future.

Our competitive position also depends, among other things, on:

Our customers’ equipment purchase considerations typically include reliability, treatment quality, service capabilities, patient throughput, price, payment terms and equipment supplier viability. We believe we compete favorably with our competitors on price and value based upon the technology offered by our platforms. We strive to provide technologically superior products that cover substantially all aspects of radiation therapy to deliver precise treatments with high-quality clinical outcomes that meet or exceed customer expectations.

In addition to competition from technologies performing similar functions as our platforms, competition also exists for the limited capital expenditure budgets of our customers. For example, our platforms may compete with other equipment required by a radiation therapy department for financing under the same capital expenditure budget, which is typically

limited. A purchaser, such as a hospital or cancer treatment center, may be required to select between the two items of capital equipment. Our ability to compete may also be adversely affected when purchase decisions are based solely upon price, since our products are premium priced systems due to their higher level of functionality and performance.

U.S. Reimbursement

In the United States, healthcare providers that purchase capital equipment such as the CyberKnife and/or TomoTherapy platforms generally rely on government and private third-party payors for reimbursement for the healthcare treatment and services they provide. Examples of these types of payors include Medicare, Medicaid, private health insurance plans, and health maintenance organizations, which reimburse all or a portion of the cost of treatment, as well as related healthcare services. Reimbursement involves three components: coverage, coding and payment.

Coverage

There are currently no National Coverage Determinations in place under Medicare for treatments provided on a CyberKnife, TomoTherapy, or Radixact platform. Medicare coverage criteria for treatments performed on a CyberKnife, TomoTherapy, or Radixact platform is outlined in Local Coverage Determinations or, in the absence of a formal policy, treatment is covered as long as it is considered reasonable and necessary. The most common indications covered by Medicare in Local Coverage Determinations for radiotherapy are primary and metastatic tumors in the brain, spine, lung, liver, kidney, pancreas, adrenal gland, head and neck, breast, prostate, abdominal and retroperitoneal regions, as well as other cancers that have failed previous treatment. Commercial payor policies vary with respect to coverage for radiotherapy including many of the indications covered by Medicare, though coverage criteria may differ.

Coding

The codes that are used to report radiosurgery treatment delivery in 2025 for the hospital outpatient department are Current Procedural Terminology (“CPT”) codes 77372 and 77373 for single fraction intracranial radiosurgery and single fraction extracranial/multi‑session radiosurgery/stereotactic body radiation therapy. For freestanding centers, robotic radiosurgery is billed with robotic radiosurgery Healthcare Common Procedural Codes (“HCPCs”) G0339 and G0340. The non‑robotic SRS/SBRT codes 77372 and 77373 are also payable codes in the freestanding site of service for non‑robotic SRS/SBRT.

In 2025, in the hospital outpatient department, IMRT delivery is billed under CPT code 77385 for simple IMRT and 77386 for complex IMRT. For 3D CRT three codes are used to report simple, intermediate, and complex treatments. 3D-CRT treatments delivered using the TomoTherapy and Radixact Systems are considered complex treatments and reported under the complex 3D‑CRT code 77412. In December 2015, the Patient Access and Medicare Protection Act (PAMPA) stopped the IMRT and 3D CRT delivery codes from being implemented and prevented reimbursement reductions in the freestanding center setting through calendar year 2019. Although the payment freeze was set to expire on December 31, 2019, the Centers for Medicare and Medicaid Services (“CMS”) has continued to recognize these temporary HCPCS G codes in this setting. We expect all valid delivery codes will be recognized by commercial payers. Other codes are used to report treatment planning, dosimetry, treatment management, and other procedures routinely performed for treating radiosurgery or radiotherapy patients.

Payment

In the United States, most procedures using the CyberKnife, TomoTherapy, and Radixact Systems are performed in the hospital outpatient department. Payment rates under the Medicare fee-for-service methodology are established based on cost data submitted by hospitals. CMS pays separately for ancillary procedures in addition to the delivery of IMRT, 3D CRT, and SRS/SBRT as well as comprehensive ambulatory payment classifications that bundles delivery and some ancillary services for single session cranial radiosurgery.

Payment for treatment with CyberKnife and TomoTherapy platforms are also available in the freestanding center setting. In 2025, the primary treatment delivery codes for robotic radiosurgery are priced by the regional Medicare Administrative Contractors. In 2025, the robotic SRS/SBRT delivery codes remain contractor priced for providers paid under the traditional

fee-for-service methodology. Payment rates for IMRT and 3DRT procedures are set by CMS with adjustments to account for geographic market variations.

The federal government reviews and adjust rates annually, and from time to time considers various Medicare and other healthcare reform proposals that could significantly affect both private and public reimbursement for healthcare services, including radiotherapy and radiosurgery, in hospitals and free‑standing clinics. In the past, we have seen our customers’ decision making process complicated by the uncertainties surrounding reimbursement rates for radiotherapy and radiosurgery in the United States. State government reimbursement for services is determined pursuant to each state’s Medicaid plan, which is established by state law and regulations, subject to the requirements of federal law and regulations.

Foreign Reimbursement

Internationally, reimbursement and healthcare payment systems vary from country to country and include single payor, government managed systems as well as systems in which private payors and government managed systems exist side-by-side. In general, the process of obtaining coverage approvals has been slower outside of the United States. Our ability to achieve adoption of our treatment systems, and significant sales volume in international markets, will depend in part on the availability of reimbursement for procedures performed using our products.

Regulatory Matters

Domestic Regulation

Our products and software are medical devices subject to regulation by the FDA, as well as other regulatory bodies. FDA regulations govern the following activities that we perform and will continue to perform to ensure medical products distributed domestically or exported internationally are safe and effective for their intended uses:

FDA pre-market clearance and approval requirements. Unless an exemption applies, each medical device we wish to commercially distribute in the United States will require either 510(k) clearance or pre‑market approval from the FDA. The FDA classifies medical devices into one of three classes (I, II, III). The FDA categorizes devices based on risk in either class I or II, depending upon the class, the manufacturer submits the applicable pre‑market notification to the FDA requesting permission to commercially distribute the device. For class II, the FDA requires 510(k) clearance before marketing and distribution. Some low risk devices are exempted from this requirement. Devices deemed by the FDA to pose the greatest

risks, such as life‑sustaining, life‑supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) devices, are placed in class III, requiring pre‑market approval. All of our current products are class II devices requiring 510(k) clearances.

510(k) clearance pathway. When a 510(k) clearance is required, we must submit a pre‑market notification demonstrating that our proposed device is substantially equivalent to a previously cleared and legally marketed 510(k) device or a device that was in commercial distribution before May 28, 1976 for which the FDA has not yet called for the submission of pre‑market approval (“PMA”) applications. By statute, the FDA has targets to clear or deny a 510(k) pre‑market notification after 90 days of FDA review time from submission of the application. Clearance generally takes longer as the FDA may require further information, including clinical data, that require our response and pauses the 90-day review time to make a determination regarding substantial equivalence.

In January 2002, we received 510(k) clearance for the TomoTherapy Hi Art System intended to be used as an integrated system for the planning and delivery of IMRT for the treatment of cancer. In August 2008, we received 510(k) clearance for our TomoDirect System. In June 2016, we introduced the Radixact Treatment Delivery Platform with 510(k) clearance. We expanded the Radixact Treatment Delivery Platform through subsequent 510(k) clearances to include Synchrony in November 2018 for real-time adaptive motion tracking and compensation, ClearRT in November 2020 for advanced imaging, and VitalHoldTM in August 2023 for Surface Guided Radiation Therapy (“SGRT”).

In July 1999, we received 510(k) clearance for the CyberKnife System for stereotactic radiosurgery and radiotherapy in the head and neck regions of the body. We received additional 510(k) clearances for CyberKnife System and options, including in April 2002 for the Synchrony Motion Tracking System as a real-time adaptive option, intended to enable dynamic image guided stereotactic radiosurgery and precision radiotherapy of lesions, tumors and conditions that move under influence of respiration. We have grown our CyberKnife System with the July 2015 510(k) clearance of the M6 platform, including the InCise Multileaf Collimator and introducing the CyberKnife Treatment Delivery System to leverage our Accuray Precision Treatment Planning System in April 2017.

We introduced our new treatment planning and data management systems, Accuray Precision Treatment Planning System with iDMS Data Management System with 510(k) clearances in June 2016.

PMA pathway. A PMA must be submitted to the FDA if the device is not eligible for the 510(k) clearance process. A PMA must be supported by extensive data including, but not limited to, technical, preclinical, clinical trials, manufacturing and labeling to demonstrate reasonable evidence of the device’s safety and efficacy to the FDA’s satisfaction. Currently, no device we have developed and commercialized has required pre‑market approval.

Product modifications. After a device receives 510(k) clearance or a PMA approval, it may be changed or modified. Any modification that could significantly affect its safety or effectiveness, or that would constitute a significant change in its intended use, will require a new clearance or approval. Regulations provide that the manufacturer initially determines when a specific modification requires notification to FDA. The FDA has issued draft guidance that, if finalized and implemented, will result in manufacturers needing to seek a significant number of new clearances for changes made to legally marketed devices. The FDA reviews the manufacturer’s decision to file a 510(k) or PMA for modifications during facility audits.

We have modified aspects of our CyberKnife and TomoTherapy platforms since receiving initial regulatory clearance, and we have applied for and obtained additional 510(k) clearances for these modifications when we determined such clearances were required. The FDA may review our 510(k) filing decision, and can disagree with our initial determination. The FDA may take regulatory action from requiring new filings to injunction if it disagrees with our determinations not to seek a new 510(k) clearance or PMA approval for modifications.

Pervasive and continuing regulation. After a device is placed on the market, numerous regulatory requirements apply. These include:

The FDA has broad post‑market and regulatory enforcement powers, including cybersecurity as enhanced in March 2023 by the Food and Drug Omnibus Reform Act (“FDORA”). The latest FDA cybersecurity requirements apply to new devices at pre-market submission, such as 510(k) clearance. We are subject to unannounced inspections by the FDA and the Food and Drug Branch of the California Department of Health Services to determine our compliance with the QSR and other regulations, and these inspections may include the manufacturing facilities of some of our subcontractors. Our Madison facility, where we manufacture the finished TomoTherapy and CyberKnife Systems, was most recently inspected by the FDA in August 2017. The August 2017 inspection resulted in no observations. We voluntarily participate in the Medical Device Single Audit Program (“MDSAP”). The MDSAP program allows recognized Auditing Organization to conduct a single regulatory audit of a medical device manufacturer that satisfies the relevant requirements of the regulatory authorities participating in the program. The MDSAP participating members include FDA, Therapeutic Goods Administration of Australia, Brazil’s Agência Nacional de Vigilância Sanitária, Health Canada, Japan’s Ministry of Health, Labour and Welfare, and the Japanese Pharmaceuticals and Medical Devices Agency. FDA accepts MDSAP audit reports as a substitute for routine Agency inspections. We are routinely audited by an MDSAP-recognized Auditing Organization to international medical device requirements. We believe we are in substantial compliance with the QSR. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include any of the following sanctions:

The FDA also has the authority to require us to repair, replace or refund the cost of any medical device that we have manufactured or distributed. If any of these events were to occur, they could have a material adverse effect on our business.

Radiological health. Because our CyberKnife and TomoTherapy platforms contain both laser and X‑ray components, and because we assemble these components during manufacturing and service activities, we are also regulated under the Electronic Product Radiation Control Provisions of the United States Federal Food, Drug, and Cosmetic Act. This law requires laser and X‑ray products to comply with regulations and applicable performance standards, and manufacturers of these products to certify in product labeling and reports to the FDA that their products comply with all such standards. The law also requires manufacturers to file new product reports, and to file annual reports and maintain manufacturing, testing and sales records, and report product defects. Various warning labels must be affixed. Assemblers of diagnostic X‑ray systems are also required to certify in reports to the FDA, equipment purchasers, and where applicable, to state agencies responsible for radiation protection, that diagnostic and/or therapeutic X‑ray systems they assemble meet applicable requirements. Failure to comply with these requirements could result in enforcement action by the FDA, which can include injunctions, civil penalties, and the issuance of warning letters.

Fraud and abuse laws. We are subject to various federal and state laws pertaining to healthcare fraud and abuse, including anti‑kickback laws and physician self‑referral laws. Violations of these laws are punishable by significant criminal and civil sanctions, including, in some instances, exclusion from participation in federal and state healthcare programs, including Medicare and Medicaid. Because of the far‑reaching nature of these laws, there can be no assurance that we would not be required to alter one or more of our practices to be in compliance with these laws. Evolving interpretations of current

laws or the adoption of new federal or state laws or regulations could adversely affect many of the arrangements we have with customers and physicians. In addition, there can be no assurance that the occurrence of one or more violations of these laws or regulations would not result in a material adverse effect on our financial condition and results of operations.

Anti‑kickback laws. Our operations are subject to broad and changing federal and state anti‑kickback laws. The Office of the Inspector General of the Department of Health and Human Services (“OIG”) is primarily responsible for enforcing the federal Anti‑Kickback Statute and generally for identifying fraud and abuse activities affecting government programs. The federal Anti‑Kickback Statute prohibits persons from knowingly and willfully soliciting, receiving, offering or providing remuneration directly or indirectly to induce either the referral of an individual, or the furnishing, recommending, or arranging of a good or service, for which payment may be made under a federal healthcare program such as Medicare and Medicaid. “Remuneration” has been broadly interpreted to include anything of value, including such items as gifts, discounts, the furnishing of supplies or equipment, credit arrangements, waiver of payments, and providing anything of value at less than fair market value.

Penalties for violating the federal Anti‑Kickback Statute include criminal fines of up to $25,000 and/or imprisonment for up to five years for each violation, civil monetary penalties, which could result in treble damages plus fines of up to $50,000 for each violation, and possible exclusion from participation in federal healthcare programs such as Medicare and Medicaid. Many states have adopted prohibitions similar to the federal Anti‑Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source, not only by the Medicare and Medicaid programs, and do not include comparable exceptions.

The OIG has issued safe harbor regulations which set forth certain activities and business relationships that are deemed safe from prosecution under the federal Anti‑Kickback Statute. There are safe harbors for various types of arrangements, including, without limitation, certain investment interests, leases and personal services and management contracts. The failure of a particular activity to comply in all regards with the safe harbor regulations does not mean that the activity violates the federal Anti‑Kickback Statute or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy each applicable safe harbor may result in increased scrutiny by government enforcement authorities such as the OIG.

The OIG has identified the following arrangements with purchasers and their agents as ones raising potential risk of violation of the federal Anti‑Kickback Statute:

We have a variety of financial relationships with physicians who are in a position to generate business for us. For example, physicians who own our stock also provide medical advisory and other consulting or collaboration services. Similarly, we have a variety of different types of arrangements with our customers. In the case of our former placement program, certain services and upgrades were provided without additional charge based on procedure volume. In the past, we

have also provided loans to our customers. We also provide research or educational grants to customers to support customer studies related to, among other things, our CyberKnife and TomoTherapy platforms.

If our past or present operations are found to be in violation of the federal Anti‑Kickback Statute or similar government regulations to which we or our customers are subject, we or our officers may be subject to the applicable penalty associated with the violation, including significant civil and criminal penalties, damages, fines, imprisonment, and exclusion from the Medicare and Medicaid programs. The impact of any such violation may lead to curtailment or restructuring of our operations. Any penalties, damages, fines, or curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results. The risk of our being found in violation of these laws is increased by the fact that some of these laws are open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from the operation of our business and damage our reputation. If an enforcement action were to occur, our reputation and our business and financial condition could be harmed, even if we were to prevail or settle the action. Similarly, if the physicians or other providers or entities with which we do business are found to be non‑compliant with applicable laws, they may be subject to sanctions, which could also have a negative impact on our business.

Transparency laws. The Physician Payment Sunshine Act (the “Sunshine Act”), which was enacted by Congress as part of the Patient Protection and Affordable Care Act on December 14, 2011, requires each applicable manufacturer, which includes medical device companies, such as Accuray, to track and report to the federal government on an annual basis all payments and other transfers of value from such applicable manufacturer to U.S. licensed physicians and teaching hospitals as well as physician ownership of such applicable manufacturer’s equity, in each case subject to certain statutory exceptions. Such data will be made available by the government on a publicly searchable website. Failure to comply with the data collection and reporting obligations imposed by the Sunshine Act can result in civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum of $150,000 per reporting period) and from $10,000 to $100,000 for each knowing failure to report (up to a maximum of $1 million per reporting period). In addition, we are subject to similar state and foreign laws related to the tracking and reporting of payments and other transfers of value to healthcare professionals. These laws require or will require that we implement the necessary and costly infrastructure to track and report such payments and transfers of value. Failure to comply with these new tracking and reporting laws could subject us to significant civil monetary penalties.

Physician self‑referral laws. We are also subject to federal and state physician self‑referral laws. The federal Ethics in Patient Referrals Act of 1989, commonly known as the Stark Law, prohibits, subject to certain exceptions, physician referrals of Medicare and Medicaid patients to an entity providing certain “designated health services” if the physician or an immediate family member has any financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral.

In addition, in July 2008, CMS issued a final rule implementing significant amendments to the regulations under the Stark Law. The final rule, which was effective October 1, 2009, imposes additional limitations on the ability of physicians to refer patients to medical facilities in which the physician or an immediate family member has an ownership interest for treatment. Among other things, the rule provides that leases of equipment between physician owners that may refer patients and hospitals must be on a fixed rate, rather than a per use basis. Prior to enactment of the final rule, physician owned entities had increasingly become involved in the acquisition of medical technologies, including the CyberKnife platform. In many cases, these entities entered into arrangements with hospitals that billed Medicare for the furnishing of medical services, and the physician owners were among the physicians who referred patients to the entity for services. The rule limits these arrangements and could require the restructuring of existing arrangements between physicians owned entities and hospitals and could discourage physicians from participating in the acquisition and ownership of medical technologies. The final rule also prohibits percentage‑based compensation in equipment leases. As a result of the finalization of these regulations, some existing CyberKnife platform operators have modified or restructured their corporate or organizational structures. In addition, certain customers that planned to open CyberKnife centers in the United States involving physician ownership have restructured their legal ownership structure. Certain entities were not able to establish viable models for CyberKnife platform operation and therefore, canceled their CyberKnife platform purchase agreements. Accordingly, these regulations have resulted in cancellations of CyberKnife platform purchase agreements and could also reduce the attractiveness of medical technology acquisitions, including CyberKnife platform purchases, by physician owned joint ventures or similar entities. As a result, these regulations have had, and could continue to have, an adverse impact on our product sales and therefore, on our business and results of operations.

A person who engages in a scheme to circumvent the Stark Law’s referral prohibition may be fined up to $100,000 for each such arrangement or scheme. In addition, any person who presents or causes to be presented a claim to the Medicare or Medicaid programs in violations of the Stark Law is subject to civil monetary penalties of up to $15,000 per bill submission, an assessment of up to three times the amount claimed, and possible exclusion from federal healthcare programs such as Medicare and Medicaid. Various states have corollary laws to the Stark Law, including laws that require physicians to disclose any financial interest they may have with a healthcare provider to their patients when referring patients to that provider. Both the scope and exceptions for such laws vary from state to state.

Federal False Claims Act. The federal False Claims Act prohibits the knowing filing or causing the filing of a false claim or the knowing use of false statements to obtain payment from the federal government. When an entity is determined to have violated the False Claims Act, it may be required to pay three times the actual damages sustained by the government, plus mandatory civil penalties of between $13,946 and $27,894 for each separate false claim. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, sometimes known as “relators” or, more commonly, as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. In addition, certain states have enacted laws modeled after the federal False Claims Act. Qui tam actions have increased significantly in recent years, causing greater numbers of healthcare companies to have to defend a false claim action, pay fines or be excluded from Medicare, Medicaid or other federal or state healthcare programs as a result of an investigation arising out of such action. We have retained the services of a reimbursement consultant, for which we pay certain consulting fees, to provide us and facilities that have purchased a CyberKnife or TomoTherapy platform, with general reimbursement advice. While we believe this will assist our customers in filing proper claims for reimbursement, and even though such consultants do not submit claims on behalf of our customers, the fact that we provide these consultant services could expose us to additional scrutiny and possible liability in the event one of our customers is investigated and determined to be in violation of any of these laws.

HIPAA. The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), created two new federal crimes: healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private payors. A violation of this statute is a felony and may result in fines, imprisonment or exclusion from government sponsored programs. The false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in fines or imprisonment.

As a participant in the healthcare industry, we are also subject to extensive federal and state laws and regulations protecting the privacy and integrity of patient medical information, including privacy and security standards required under HIPAA. The HIPAA privacy standard was amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), enacted as part of the American Recovery and Reinvestment Act of 2009. HITECH significantly increases the civil money penalties for violations of patient privacy rights protected under HIPAA. Although we are not a covered entity under HIPAA, we have entered into agreements with certain covered entities under which we are considered to be a “business associate” under HIPAA. As a business associate, we are required to implement policies, procedures and reasonable and appropriate security measures to protect individually identifiable health information we receive from covered entities. Furthermore, business associates are directly subject to regulations under HIPAA including the new enforcement scheme, criminal and civil penalties for certain violations, and inspection requirements.

Foreign Corrupt Practices Act. The United States and foreign government regulators have increased regulation, enforcement, inspections and governmental investigations of the medical device industry, including increased United States government oversight and enforcement of the Foreign Corrupt Practices Act. Whenever the United States or another foreign governmental authority concludes that we are not in compliance with applicable laws or regulations, such governmental authority can impose fines, delay or suspend regulatory clearances, institute proceedings to detain or seize our products, issue a recall, impose operating restrictions, enjoin future violations and assess civil penalties against us or our officers or employees, and can recommend criminal prosecution to the Department of Justice. Moreover, governmental authorities can ban or request the recall, repair, replacement or refund of the cost of any device or product we manufacture or distribute. In addition, our third party agents in foreign countries can also subject us to prosecution under Foreign Corrupt Practices Act. We are also subject to the UK Bribery Act, which could also lead to the imposition of civil and criminal fines and other similar anti-bribery and anti-corruption laws. Any of the foregoing actions could result in decreased sales as a result of negative publicity and product liability claims, and could have a material adverse effect on our financial condition, results of operations and prospects.

International Regulation

International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. The time required to obtain clearance or approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements are often different.

The primary regulatory environment in Europe is that of the European Union and the three additional member states of the European Economic Area (“EEA”), which have adopted similar laws and regulations with respect to medical devices. The European Union has adopted numerous regulations and directives and the European Committee for Standardization has promulgated standards regulating the design, manufacture, clinical trials, labeling and adverse event reporting for medical devices. Devices that comply with the requirements of the relevant regulation or directive will be entitled to bear the Conformité Européene (“CE”) conformity marking, indicating that the device conforms to the essential requirements of the applicable directives and, accordingly, may be commercially distributed throughout the member states of the EEA.

The method of assessing conformity to applicable regulations, directives, and standards depends on the type and class of the product, but normally involves a combination of self‑assessment by the manufacturer and a third‑party assessment by a notified body, an independent and neutral institution appointed by a European Union member state to conduct the conformity assessment. This relevant assessment may consist of an audit of the manufacturer’s quality system (currently ISO 13485), provisions of the Medical Devices Regulation (“MDR”) and specific testing of the manufacturer’s device. Our facilities were first awarded the ISO 13485 certification in September 2002 and has been subsequently maintained through periodic assessments. The European Union MDR was published in May 2017 and came into effect in May 2021. We are currently authorized to affix the CE mark under the MDR to our products, allowing us to sell our products throughout the European Economic Area. We are required to obtain certification against the MDR to CE mark new products or to make significant changes to existing products. Under the MDR, our notified body may review the technical and clinical details of a product before permitting the CE mark for new products or significant changes. There are fewer notified bodies authorized under the MDR to qualify businesses and products. This may result in additional time for initial product reviews and to obtain authorization to apply the CE mark.

We are also currently subject to regulations in Japan. Under the Pharmaceutical Affairs Law in Japan, a pre‑market approval necessary to sell, market and import a product (Shonin) must be obtained from the Ministry of Health, Labor and Welfare (“MHLW”), for our products. A Japanese distributor received the first government approval to market the CyberKnife System from MHLW in November 1996. We received and maintain Shonin approval from MHLW for CyberKnife Treatment Delivery Systems, M6 Series with InCise MLC, TomoTherapy Treatment Delivery Systems, Radixact Treatment Delivery Systems, and associated Precision and iDMS software products.

Additionally, our products are subject to regulations in China. The China Supervision and Regulation of Medical Devices (No. 680) requires licensing from the NMPA to market, sell, and import our product type. Before application, the NMPA licenses require testing by a laboratory accredited in China, such as the Beijing Institute for Medical Devices Testing (“BIMT”) or Liaoning Medical Device Test Institute (“LMTI”). China has adopted international standards for safety and performance with national variations specific to China. We received and maintain NMPA licenses for various configurations of Radixact Treatment Delivery Systems, CyberKnife Treatment Delivery Systems, TomoTherapy Treatment Delivery Systems, and Precision (including iDMS) software products.

We are subject to additional regulations in other foreign countries, including, but not limited to, Canada, Taiwan, Korea, and Russia in order to sell our products. We expect that either we or our distributors will receive any necessary approvals or clearance prior to marketing or importing our products as required by international markets.

State Certificate of Need Laws

In some states, a certificate of need or similar regulatory approval is required prior to the acquisition of high‑cost capital items or the provision of new services. These laws generally require appropriate state agency determination of public need and approval prior to the acquisition of such capital items or addition of new services. Certificate of need regulations may preclude our customers from acquiring one of our systems, and from performing stereotactic radiosurgery procedures using one of our systems. Several of our prospective customers currently are involved in appeals of certificate of need determinations. If these appeals are not resolved in favor of these prospective customers, they may be precluded from purchasing and/or performing services using one of our systems. Certificate of need laws are the subject of continuing

legislative activity, and a significant increase in the number of states regulating the acquisition and use of one of our systems through certificate of need or similar programs could adversely affect us.

Employees and Human Capital Resources

Our employees are critical to the success of our business. As of June 30, 2025, we had 990 employees, including 432 employees employed outside of the United States. We also engage part-time employees and independent contractors to supplement our workforce. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We have never experienced any employment-related work stoppages, and we believe our relationship with our employees is good. We are dedicated to cultivating a diverse and inclusive work environment, essential for attracting and retaining exceptional talent. We believe that much of Accuray’s work can be done in a workplace which consists of a blend of flexible, digitally enabled remote work and purposeful in-person connection and collaboration; we have learned the importance of providing flexibility and wellbeing resources to our employees. Through ongoing employee development, comprehensive compensation and benefits, and other programs, we strive to help our employees in all aspects of their lives so they can do their best work.
 

Talent Development

We believe that investing in our employees' development is essential for maintaining our competitive edge and fostering a culture of innovation and excellence. We offer various opportunities for our employees to enhance their skills, knowledge, and leadership abilities, such as online courses, mentoring programs, coaching sessions, and career development plans. We also conduct regular performance reviews and feedback surveys to assess our employees' strengths, areas for improvement, and career aspirations. Our goal is to enable our employees to achieve their full potential and grow with the company.

Compensation & Benefits

The principal purposes of our compensation and incentive plans are to attract, retain, and reward personnel, in order to increase stockholder value and the success of our company by motivating our employees to perform to the best of their abilities and achieve our objectives. Accordingly, we seek to offer competitive compensation and benefits packages that align with our business objectives and reward our employees for their achievements. We also provide various incentives and recognition programs, such as equity awards, bonuses, service awards, and employee referral bonuses, to motivate and appreciate our employees. In addition to the comprehensive and competitive health plans that we offer, our employees receive access to the following benefits: a 401(k) retirement plan with a company match, an employee stock purchase plan, a company-provided basic life insurance and disability benefits, a corporate wellness program, an employee assistance program, and local employee discounts programs.

Item 1A. RISK FACTORS

Risk Factors Summary

Our business is subject to numerous risks and uncertainties, including those highlighted in Part I, Item 1A titled “Risk Factors.” These risks include, but are not limited to, the following:

Risks related to our business and results of operations

Risks related to the regulation of our products and business

Risks related to our common stock

General Risks

Risk Factors

We operate in a rapidly changing environment that involves significant risks, a number of which are beyond our control. In addition to the other information contained in this Form 10‑K, the following discussion highlights some of these risks and

the possible impact of these factors on our business, financial condition and future results of operations. If any of the following risks actually occur, our business, financial condition or results of operations may be adversely impacted, causing the trading price of our common stock to decline. In addition, these risks and uncertainties may impact the “forward‑looking” statements described elsewhere in this Form 10‑K and in the documents incorporated herein by reference. They could affect our actual results of operations, causing them to differ materially from those expressed in “forward‑looking” statements.

Risks Related to Our Business and Results of Operations

We face risks related to the current global economic environment, including risks arising in connection with tariffs, inflation, recession or currency fluctuations, any of which could adversely affect our business, financial condition and results of operations by, among other things, delaying or preventing our customers from obtaining financing to purchase our products and services or implementing the required facilities to house our systems.

Our business and results of operations are materially affected by conditions in the global markets and the economy generally. We expect that the business of our customers and our own business will continue to be adversely impacted, directly or indirectly, by macroeconomic and geopolitical issues. Concerns over economic and political stability; inflation levels and related efforts to mitigate inflation; a potential recession; the level of U.S. national debt, the U.S. debt credit rating and U.S. budgetary concerns; currency fluctuations and volatility; the rate of growth of Japan, China and other Asian economies, including the impact of the China anti-corruption campaign and timing of China stimulus program on those economies; unemployment; the availability and cost of credit; trade relations, including the imposition of various sanctions, export controls, and tariffs by the United States and other countries; energy costs; instability in the banking and financial services sector; geopolitical uncertainty and conflict, including with respect to Russia-Ukraine and the Middle East conflicts, including with respect to Iran; changes in government administration policy positions and recent executive orders to impose new tariffs on global imports that could result in additional tariffs on specific industries, and uncertainties regarding impact, retaliations and further escalation, have contributed to increased volatility and diminished expectations for the economy and the markets in general. In turn, periods of economic slowdown or recession could lead to a reduction in demand for our products and services, which in turn would reduce our revenues and adversely affect our results of operations and our financial position. The results of these macroeconomic conditions, and the actions taken by governments, central banks, companies, and consumers in response, have and may continue to result in higher inflation in the U.S. and globally, which has led to an increase in costs and caused changes in fiscal and monetary policy, including increased interest rates. Other adverse impacts of recent macroeconomic conditions that have impacted us and may continue to impact us are foreign exchange rate fluctuations, supply chain constraints, logistics challenges, and fluctuations in labor availability. Thus, if general macroeconomic conditions deteriorate, our business and financial results could be materially and adversely affected.

In an inflationary environment, we may be unable to raise the prices of our products and services sufficiently to keep up with the rate of inflation. Impacts from inflationary pressures could be more pronounced and materially adversely impact aspects of our business where revenue streams and cost commitments are linked to contractual agreements that extend many years into the future, as we may not be able to quickly or easily adjust pricing, reduce costs, or implement counter measures. A higher inflationary environment can also negatively impact raw material, component, and logistics costs that, in turn, has increased the costs of producing and distributing our products. For example, inflationary pressures as well as ongoing supply chain challenges beginning in fiscal year 2023 have resulted in rising costs for certain materials, including increased logistics and duties costs, that have materially affected our gross margins and net income (loss), which have had a material effect on our business, financial condition or results of operations. We expect that gross margins and net income (loss) will continue to be adversely affected by increased material costs and freight and logistics expenses through at least calendar year 2025, and potentially longer. In addition, we expect inflation and the ongoing supply chain challenges and logistics costs to impact our cash from operations through at least calendar year 2025, as we are unable to pass all of these increased costs to our customers.

Further, the U.S. federal government has called for, or enacted, substantial changes to healthcare, trade, fiscal, and tax policies, which may include changes to existing trade agreements and may have a significant impact on our operations. For example, the United States has imposed tariffs on many foreign products, including tariffs on imports from China, that in the past have resulted in and may result in future retaliatory tariffs on U.S. goods and products and restrictions on exports to the United States. In light of the uncertainty surrounding tariffs imposed by the United States and China and trade relations between the two countries, we expect the volume of product sales in China to decrease and costs associated with tariffs to increase. We cannot predict whether these policies will continue, or if new policies will be enacted, or the impact, if any, that

any policy changes could have on our business. In addition, failure of the U.S. Government to pass a budget in a timely manner or any reductions in healthcare spending in the budget may adversely impact us or our customers. If economic conditions worsen, or new legislation is passed related to the healthcare system, trade, fiscal or tax policies, customer demand may not materialize to levels we require to achieve our anticipated financial results, which could have a material adverse effect on our business, financial condition and results of operations.

The uncertain macroeconomic environment, including volatile credit markets and concerns regarding the availability and cost of credit, increased interest rates, inflation, reduced economic growth or a recession, instability in the banking and financial services sector, and changes in government administration policy positions, in any of the geographic areas where we do business, could impact consumer and customer demand for our products and services, as well as our ability to manage normal commercial relationships with our customers, suppliers and creditors, including financial institutions, and the ability of our customers to meet their obligations to us. For example, in the United States, at least one customer declared bankruptcy in fiscal 2023 causing us to increase our bad debt reserve due to the expectation that they will be unable to pay us. Further, some of our customers have been delayed in obtaining, or have not been able to obtain, necessary financing for their purchases of the CyberKnife or TomoTherapy platforms. In addition, some of our customers have been delayed in obtaining, or have not been able to obtain, necessary financing for the construction or renovation of facilities to house the CyberKnife or TomoTherapy platforms, the cost of which can be substantial. These delays have, in some instances, led to our customers postponing the shipment and installation of previously ordered systems or cancelling their system orders and may cause other customers to postpone their system installation or to cancel their agreements with us. Reduced budgets and lower capital deployment priority for radiotherapy equipment, along with longer customer installation timelines, in the United States have also negatively impacted our net revenue since fiscal year 2024, and we expect this will continue to have an impact through fiscal year 2026. A continuation or further deterioration of the adverse economic environment would further increase delays and order cancellations, or affect our ability to collect from our customers, any of which would continue to adversely affect revenues, and therefore, harm our business and results of operations.

If the CyberKnife or TomoTherapy platforms do not achieve widespread market acceptance, we will not be able to generate the revenue necessary to support our business.

Achieving physician, patient, hospital administrator and third‑party payor acceptance of the CyberKnife and TomoTherapy platforms as preferred methods of tumor treatment is crucial to our continued success. Physicians will not begin to use or increase the use of the CyberKnife or TomoTherapy platforms unless they determine, based on experience, clinical data and other factors, that the CyberKnife and TomoTherapy platforms are safe and effective alternatives to traditional treatment methods. Further, physicians may be slow to adopt new or updated versions of our CyberKnife and TomoTherapy platforms because of the perceived liability risks arising from the use of new products and the uncertainty of reimbursement from third-party payors, particularly in light of ongoing health care reform initiatives and the evolving U.S. health care environment. If we are not able to expand market acceptance of our products and maintain and increase our base of installed systems, or installed base, then sales of our products may not meet expectations. Any failure to expand and protect our existing installed base could adversely affect our operating results.

We often need to educate physicians about the use of stereotactic radiosurgery, image guided radiation therapy (“IGRT”) and adaptive radiation therapy, convince healthcare payors that the benefits of the CyberKnife and TomoTherapy platforms and their related treatment processes outweigh their costs, and help train qualified physicians in the skilled use of these systems. In addition, we also must educate prospective customers regarding the entire functionality of our radiation therapy systems and their relative benefits compared to alternative products and treatment methods. We must also increase awareness among potential patients, who are increasingly educated about treatment options and therefore, impact adoption of new technologies by clinicians. We have expended and will continue to expend significant resources on marketing and educational efforts to create awareness of stereotactic radiosurgery and robotic intensity-modulated radiotherapy (“IMRT”) as well as adaptive radiation therapy and IGRT generally and to encourage the acceptance and adoption of our products for these technologies. We cannot be sure that our products will gain significant market acceptance among physicians, patients and healthcare payors, even if we spend significant time and expense on their education.

In addition to achieving market acceptance of our products and the need to educate physicians and others about the benefits of our products, the CyberKnife and TomoTherapy platforms are major capital purchases, and purchase decisions are greatly influenced by hospital administrators who are subject to increasing pressures to reduce costs. These and other factors, including the following, may affect the rate and level of market acceptance of the CyberKnife and TomoTherapy platforms:

If the CyberKnife or TomoTherapy platforms are unable to achieve or maintain market acceptance, new orders and sales of our systems would be adversely affected, our revenue levels would decrease and our business would be harmed.

Our ability to achieve profitability depends in part on maintaining or increasing our gross margins on product sales and services, which we may not be able to achieve.

As of June 30, 2025, we had an accumulated deficit of $519.3 million. We have incurred net losses, and expect to incur net losses in the future, particularly as selling and marketing activities increase ahead of any expected revenue. Our ability to achieve and sustain long‑term profitability is largely dependent on our ability to successfully market and sell the CyberKnife and TomoTherapy platforms, control our costs, and effectively manage our growth. We cannot assure you that we will be able to achieve profitability and even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. In the event we fail to achieve profitability, our stock price could decline.

Our ability to achieve profitability also depends on our ability to maintain or increase our gross margins on product sales and services. A number of factors have adversely impacted or could impact gross margins, including:

If we are unable to maintain or increase our gross margins on product sales and service, our results of operations could be adversely impacted, we may not achieve profitability and our stock price could decline.

We have substantial indebtedness in the form of a credit facility and convertible senior notes and may incur other debt in the future, which may adversely affect our financial condition and future financial results. In the past, we have not been in compliance with certain financial covenants relating to our indebtedness and have been required to obtain waivers to avoid defaulting under such indebtedness.

As of June 30, 2025, we had outstanding borrowings of $150 million under our five-year term loan (the “Term Loan Facility”) with additional borrowings available of $20 million under our revolving credit facility (the “Revolving Credit Facility”) and $20 million under our delayed draw term loan (the “Delayed Draw Facility” and together with the Term Loan Facility and Revolving Credit Facility, the “Credit Facilities”), each of which will mature on June 6, 2030, and $18.0 million in principal amount outstanding of our 3.75% Convertible Senior 2026 Notes due June 1, 2026 (the “2026 Notes”). Our existing and future levels of indebtedness could have important consequences to stockholders and note holders and may adversely affect our financial conditions and future financial results by, among other things:

Concurrently and in connection with our entry into the credit agreement governing the Credit Facilities (the “Financing Agreement”), we issued to our lenders (i) an aggregate of 17,180,710 shares of our common stock issuable upon exercise of outstanding warrants (the “Premium Warrants”), which are exercisable starting on December 7, 2025 and until June 6, 2032 and have an exercise price of $1.68 per share, and (ii) an aggregate of 6,247,531 shares of our common stock issuable upon exercise of warrants (the “Penny Warrants” and, together with the Premium Warrants, the “Warrants”), which are exercisable until June 6, 2032 and have an exercise price of $0.01 per share.

The Financing Agreement also includes certain restrictive covenants that limit, among other things, our ability and our subsidiaries’ ability to (i) incur indebtedness, (ii) incur liens on their property, (iii) pay dividends or make other distributions, (iv) sell their assets, (v) make certain loans or investments, (vi) merge or consolidate, (vii) voluntarily repay or prepay certain indebtedness and (viii) enter into transactions with affiliates, in each case, subject to certain exceptions. In addition, such agreements require us to meet certain financial covenants, including a fixed charge coverage ratio, total leverage ratio and liquidity level, as defined in the Financing Agreement. These restrictions could adversely affect our ability to finance our future operations or capital needs, withstand a future downturn in our business or the economy in general, engage in business activities, including future opportunities that may be in our interest, and plan for or react to market conditions or otherwise execute our business strategies. Our ability to comply with the covenants and other terms governing the Credit Facilities will depend in part on our future operating performance. If we fail to comply with such covenants and terms, we may be in default and the maturity of the related debt could be accelerated and become immediately due and payable. In addition, because substantially all of our assets are pledged as a security under the Credit Facilities, if we are not able to cure any default or repay outstanding borrowings, such assets are subject to the risk of foreclosure by our lenders. From time to time, we have not been in compliance with certain similar covenants or other terms governing the prior credit facilities and we have been required to obtain waivers or amendments to the previous credit agreement from our lenders in order to maintain compliance. There can, however, be no certainty that any such waiver or amendment will be available to us in the future, which may lead to a default under the terms of the Financing Agreement governing the Credit Facilities, or what the cost of such waiver or amendment, if obtained, would be. If we are unable to obtain necessary waivers or relevant amendments as required and the debt under such credit facility is accelerated, we would be required to obtain replacement financing at prevailing market rates, which may not be available to us on favorable terms or at all. Failure to obtain replacement financing could result in

certain of our long-term indebtedness being reclassified current, which could in turn impact our ability to continue as a going concern. Additionally, a default on indebtedness would likely result in a default under the terms of the indenture governing the 2026 Notes. We may not be able to satisfy our obligations if any of our indebtedness is accelerated.

In addition, the Credit Facilities expose us to interest rate risk. If the amount outstanding under the Credit Facilities remained at the level outstanding as of June 30, 2025 for the next 12 months and interest rates increased or decreased by 50 basis point change, our annual interest expense would increase or decrease, respectively, approximately $0.8 million.

Enhanced international tariffs, including tariffs imposed by the United States and China that affect our products or components within our products, other trade barriers or a global trade war could decrease the volume of product sales in China and increase our costs and materially and adversely affect our business condition and results of operations.

Our global business has been and could continue to be negatively affected by trade barriers and other governmental protectionist measures, any of which can be imposed or modified suddenly and unpredictably. There is currently significant uncertainty about the future relationship between the U.S. and various other countries, most significantly China, with respect to trade policies, treaties, government regulations and tariffs and such uncertainty could continue with the changes in government administration policy positions. Recently, the U.S. presidential administration has indicated its intent to modify U.S. trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. It has also imposed or announced tariffs on certain imports, including a baseline tariff of 10% on virtually all imports, higher tariffs on imports from China, as well as certain imports from Mexico and Canada. The administration has also announced and subsequently paused higher tariffs on additional countries, including the European Union pending the outcome of trade negotiations. These tariffs affect component parts including the linear accelerator for our CyberKnife platforms, which we manufacture in China and import into the U.S., as well as other components that we import into the U.S. from other suppliers, which could significantly impact the cost of these parts. Any retaliatory tariffs could also impact our ability to export and sell our products into those countries. For example, during the last half of calendar year 2018, the U.S. federal government imposed a series of tariffs ranging from 10% to 25% on a variety of imports from China, to which China responded with retaliatory tariffs ranging from 5% to 25% on a wide range of products from the U.S., which included certain of our products. If these tariffs continue, if additional tariffs are placed on certain of our components or products, or if any related counter-measures are taken by China, the U.S. or other countries, our business, financial condition and results of operations may be materially harmed. We have experienced increased costs associated with tariffs and in light of continued uncertainty surrounding tariffs imposed by the United States and China, and overall trade relations between the two countries, the volume of our product sales in China may decrease. An increase in our costs could require us to raise prices on our products, which may negatively impact the demand for our products in the affected market. We may not be able to forecast such impacts accurately. Although we continue to work with our vendors and customers to mitigate our exposure to current or potential tariffs, there can be no assurance that we will be able to offset any increased costs. The ultimate impact of any tariffs will depend on various factors, including if any tariffs are ultimately implemented, the timing of implementation, and the amount, scope, and nature of the tariffs. If we are not successful in offsetting the impact of any such tariffs, our revenue, gross margins and operating results may be adversely affected.

These tariffs are subject to a number of uncertainties as they are implemented, including future adjustments and changes. The ultimate reaction of other countries and the impact of these tariffs or other actions on the U.S., the global economy and our business, financial condition and results of operations, cannot be predicted at this time, nor can we predict the impact of any other developments with respect to global trade. Further, the imposition of additional tariffs by the U.S. could result in the adoption of additional tariffs by other countries, as well as export controls and further retaliatory actions by any affected country. Any resulting trade war could negatively impact the global market for medical devices, including radiation therapy devices, and could have a significant adverse effect on our business. These developments may have a material adverse effect on global economic conditions and the stability of global financial markets, and they may significantly reduce global trade. Any of these factors could depress economic activity, restrict our access to customers and have a material adverse effect on our business, financial condition and results of operations.

In addition, economic sanctions imposed by the United States and other countries could negatively affect our global business. For example, following Russia’s invasion of Ukraine, the United States and other countries imposed economic sanctions and severe export control restrictions against Russia and Belarus, and the United States and other countries could impose wider sanctions and export restrictions and take other actions should the conflict further escalate. Any exports or sales of our products into Russia and Belarus may be impacted by these restrictions. For instance, we are not able to ship certain spare or replacement parts into Russia and Belarus, which impacts our distributor's ability to service our installed base in such

countries as we have distributors in Russia. The military conflict in Ukraine has also led to an expansion of sanction programs imposed against Russia by the United States, Canada, the EU, the United Kingdom, Switzerland, and Japan, among others, that in relevant part, impose sanctions against some of the largest state-owned and private Russian financial institutions (and their subsequent removal from the Society for Worldwide Interbank Financial Telecommunication (“SWIFT”) payment system) and certain Russian businesses, some of which have significant financial and trade ties to the EU, making it increasingly difficult to transfer money from Russia to other countries. In response to international sanctions, and as part of measures to stabilize and support the volatile Russian financial and currency markets, the Russian authorities imposed significant currency control measures aimed at restricting the outflow of foreign currency and capital from Russia, imposed various restrictions on transacting with non-Russian parties, banned exports of various products and imposed other economic and financial restrictions. If we are unable to receive payment from customers in Russia or transfer money outside of Russia, it could affect our ability to convert backlog from that region into revenue. The situation continues to evolve, and the United States, the EU, the United Kingdom and other countries may implement additional sanctions, export controls or other measures against Russia and other countries, regions, officials, individuals or industries in the respective territories. Such sanctions and measures, as well as existing and potential further responses from Russia or other countries, could adversely affect the global economy and financial markets, as well as our business, financial condition and results of operations, which may also magnify the impact of other risks described in this “Risk Factors” section.

Our operating results, including our cash flows, quarterly orders, revenues and margins fluctuate from quarter to quarter and may be unpredictable.

We have experienced and expect in the future to experience fluctuations in our operating results, including gross orders, revenues and margins, from period to period. Drivers of orders include the introduction and timing of new product or product enhancement announcements by us and our competitors, the timing of regulatory approvals, changes in price by us and our competitors as well as changes or anticipated changes in third‑party reimbursement amounts or policies applicable to treatments using our products. The availability of economic stimulus packages or other government funding, or reductions thereof, may also affect timing of customer purchases. Our products have a high unit price and require significant capital expenditures by our customers. Accordingly, we experience long sales and implementation cycles, which is of greater concern during a volatile economic environment where we have had customers delay or cancel orders. The timing of when orders are placed, when installation, delivery or shipping, as applicable, is accomplished and when revenue is recognized affect our quarterly results. Further, because of the high unit price of the CyberKnife and TomoTherapy platforms and the relatively small number of units sold or installed each quarter, each sale or installation of a CyberKnife or TomoTherapy platform can represent a significant percentage of our net orders, backlog or revenue for a particular quarter and shifts in sales or installation from one quarter to another may have significant effects. For example, multi-system sales or sales involving negotiations with integrated delivery networks involve additional complexities to the transaction and require a longer timeline to finalize the sale, which make it more difficult to predict the quarter in which the sale will occur. In addition, we have experienced delays in orders and installations due to the impact of macroeconomic factors.

Once orders are received and booked into backlog, there is a risk that we may not recognize revenue in the near term or at all. The pace at which backlog converts to revenue has been adversely impacted in recent years, primarily due to delays in the timing of deliveries and installations in fiscal 2020 through 2022 caused by the COVID-19 pandemic and the resulting effects on the global economic environment. These delays in deliveries and installations could occur again in the future, which could have a negative impact on our revenue. Factors that may affect whether these orders become revenue (or are cancelled or deemed aged‑out and reflected as a reduction in net orders) and the timing of revenue include:

Our operating results have previously and may in the future also be affected by a number of other factors, some of which are outside of our control, including:

Because many of our operating expenses are based on anticipated sales and a high percentage of these expenses are fixed for the short term, a small variation in the timing of revenue recognition can cause significant variations in operating results from quarter to quarter. If our financial results fall below the expectation of securities analysts and investors, the trading price of our common stock would almost certainly decline.

We report our orders and backlog on a quarterly and annual basis. Unlike revenues, orders and backlog are not defined by United States generally accepted accounting principles (“U.S. GAAP”), and are not within the scope of the audit conducted by our independent registered public accounting firm. Also, for the reasons discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations, our orders and backlog cannot necessarily be relied upon as accurate predictors of future revenues. Order cancellation or significant delays in installation date will reduce our backlog and future revenues, and we cannot predict if or when orders will mature into revenues. Particularly high levels of cancellations or age-outs in one or more periods may cause our revenue and gross margins to decline in current or future periods and will make it difficult to compare our operating results from quarter to quarter. We cannot assure you that our backlog will result in revenue on a timely basis or at all, or that any cancelled contracts will be replaced.

Our industry is subject to intense competition and rapid technological change, which may result in products or new tumor treatments that are superior to the CyberKnife and TomoTherapy platforms. If we are unable to anticipate or keep pace with changes in the marketplace and the direction of technological innovation and customer demands, our products may become obsolete or less useful and our operating results will suffer.

The medical device industry in general and the non‑invasive cancer treatment field in particular are subject to intense and increasing competition and rapidly evolving technologies. Because our products often have long development and government approval cycles, we must anticipate changes in the marketplace and the direction of technological innovation and customer demands. To compete successfully, we will need to continue to demonstrate the advantages of our products and technologies over well‑established alternative procedures, products and technologies, and convince physicians and other healthcare decision makers of the advantages of our products and technologies. Traditional surgery and other forms of minimally invasive procedures, brachytherapy, chemotherapy or other drugs remain alternatives to the CyberKnife and TomoTherapy platforms.

We consider the competition for the CyberKnife and TomoTherapy platforms to be existing radiation therapy systems, primarily using C‑arm linacs, which are sold by large, well‑capitalized companies with significantly greater market share and resources than we have. Several of these competitors are also able to leverage their fixed sales, service and other costs over multiple products or product lines. In particular, we compete with a number of existing radiation therapy equipment companies, including Varian Medical Systems, Inc., a Siemens Healthineers company (“Varian”), Elekta AB (“Elekta”), RefleXion Medical Inc. and Zap Surgical Systems. Varian has been the leader in the external beam radiation therapy market for many years and has the majority market share for radiation therapy systems worldwide. In general, because of aging demographics and attractive market factors in oncology, we believe that new competitors will enter the radiosurgery and radiation therapy markets in the years ahead. In addition, some manufacturers of conventional linac based radiation therapy systems, including Varian and Elekta, have products that can be used in combination with body and/or head frames and image guidance systems to perform both radiosurgical and radiotherapy procedures.

Furthermore, many government, academic and business entities are investing substantial resources in research and development of cancer treatments, including surgical approaches, radiation treatment, MRI‑guided radiotherapy systems, proton therapy systems, radiopharmaceutical/pharmaceutical treatments, gene therapy (which is the treatment of disease by replacing, manipulating, or supplementing nonfunctional genes) and other approaches. Successful developments that result in new approaches for the treatment of cancer could reduce the attractiveness of our products or render them obsolete.

Our future success will depend in large part on our ability to establish and maintain a competitive position in current and future technologies. Rapid technological development may render the CyberKnife and TomoTherapy platforms and their technologies obsolete. Many of our competitors have or may have greater corporate, financial, operational, sales and marketing resources, and more experience and resources in research and development than we have. We cannot assure you that our competitors will not succeed in developing or marketing technologies or products that are more effective or commercially attractive than our products or that would render our technologies and products obsolete or less useful. We may not have the financial resources, technical expertise, marketing, distribution or support capabilities to compete successfully in the future. In addition, some of our competitors may compete by changing their pricing model or by lowering the price of their products. If we are unable to maintain or increase our selling prices, our revenue and gross margins may suffer. Our success will depend in large part on our ability to maintain a competitive position with our technologies.

In addition to competition from technologies performing similar functions as our platforms, competition also exists for the limited capital expenditure budgets of our customers. For example, our platforms may compete with other equipment required by a radiation therapy department for financing under the same capital expenditure budget, which is typically limited. A purchaser, such as a hospital or cancer treatment center, may be required to select between the two items of capital equipment. Our ability to compete may also be adversely affected when purchase decisions are based solely upon price, since our products are premium‑priced systems due to their higher level of functionality and performance.

We are subject to risks arising from our international operations, which may adversely affect our business, financial condition, and results of operations.

We derive most of our revenue from our international operations, and we plan to continue expanding our business in international markets in the future. In addition, we have employees engaged in R&D, manufacturing, administration, manufacturing, support and sales and marketing activities.

As a result of our international operations, in addition to similar risks we face in our U.S. operations, we are affected by economic, business, regulatory, social, and political conditions in foreign countries, including the following:

Our inability to overcome these obstacles could harm our business, financial condition and operating results. Even if we are successful in managing these obstacles, our partners internationally are subject to these same risks and may not be able to manage these obstacles effectively.

In addition, our partners internationally are subject to these same risks. If we or our partners are impacted by any of these factors, our business, financial condition and operating results could be adversely affected.

Our results have been and may continue to be impacted by changes in foreign currency exchange rates.

Our operating results are subject to volatility due to fluctuations in foreign currency exchange rates. Currently, the majority of our international sales are denominated in U.S. Dollars. As a result, an increase in the value of the U.S. Dollar relative to foreign currencies could require us to reduce our sales price or make our products less competitive in international markets. Foreign exchange has previously been and could in the future be a significant headwind if the U.S. Dollar strengthens, which could affect our results of operations and could cause potential delays in orders and we may see our sales and margins outside of the U.S. decline as we may not be able to raise local prices to fully offset any strengthening of the U.S. Dollar. Also, if our international sales continue to increase, we may enter into a greater number of transactions denominated in non‑U.S. Dollars, which would expose us to foreign currency risks, including changes in currency exchange rates. If we are unable to address these risks and challenges effectively, our international operations may not be successful and our business would be materially harmed.

If we encounter manufacturing problems, or if our manufacturing facilities do not continue to meet federal, state or foreign manufacturing standards, we may be required to temporarily cease all or part of our manufacturing operations, which would result in delays and lost revenue.

The CyberKnife and TomoTherapy platforms are complex and require the integration of a number of components from several sources of supply. We must manufacture and assemble these complex systems in commercial quantities in compliance with regulatory requirements and at an acceptable cost. Our linear accelerator components are extremely complex devices and require significant expertise to manufacture, and we may encounter difficulties in scaling up production of the CyberKnife or TomoTherapy platforms, including problems with quality control and assurance, component supply shortages, increased costs, shortages of qualified personnel, the long lead time required to develop additional radiation shielded facilities for purposes of testing our products and/or difficulties associated with compliance with local, state, federal and foreign regulatory requirements. In addition, the macroeconomic environment has and may continue to impact the supply of key components such that we may not receive them in a timely manner, in sufficient quantities, or at a reasonable cost. If component supply or our manufacturing capacity does not keep pace with demand, we will not be able to fulfill product orders or service our products in a timely manner, which in turn may have a negative effect on our financial results and overall business. Conversely, if demand for our products decreases, the fixed costs associated with excess manufacturing capacity may adversely affect our financial results.

Our manufacturing processes and the manufacturing processes of our third‑party suppliers are required to comply with the FDA’s Quality System Regulations (“QSR”) for any products imported into, or sold within, the U.S. The QSR is a complex regulatory scheme that covers the methods and documentation of the design, testing, production process and controls, manufacturing, labeling, quality assurance, packaging, storage and shipping of our products. Furthermore, we are required to verify that our suppliers maintain facilities, procedures and operations that comply with our quality requirements. We are also subject to state licensing and other requirements and licenses applicable to manufacturers of medical devices, and we are required to comply with International Organization for Standardization (“ISO”), quality system standards in order to produce products for sale in Europe and Canada, as well as various other foreign laws and regulations. Because our manufacturing processes include the production of diagnostic and therapeutic X‑ray equipment and laser equipment, we are subject to the electronic product radiation control provisions of the Federal Food, Drug and Cosmetic Act, which requires that we file reports with the FDA, applicable states and our customers regarding the distribution, manufacturing and installation of these types of equipment. The FDA enforces the QSR and the electronic product radiation control provisions through periodic inspections, some of which may be unannounced. We have been and anticipate in the future being subject to such inspections. FDA inspections usually occur every two to three years. During such inspections, the FDA may issue Inspectional Observations on Form FDA 483, listing instances where the manufacturer has failed to comply with applicable regulations and procedures, or warning letters.

If a manufacturer does not adequately address the observations, the FDA may take enforcement action against the manufacturer, including the imposition of fines, restriction of the ability to export product, total shutdown of production facilities and criminal prosecution. If we or a third‑party supplier receive a Form FDA 483 with material or major observations that are not promptly corrected, fail to pass a QSR inspection, or fail to comply with these, ISO and other applicable regulatory requirements, our operations could be disrupted and our ability to generate sales could be delayed. Our

failure to take prompt and satisfactory corrective action in response to an adverse inspection or our failure to comply with applicable standards could result in enforcement actions, including a public warning letter, a shutdown of our manufacturing operations, a recall of our products, civil or criminal penalties, or other sanctions, which would cause our sales and business to suffer. In addition, because some foreign regulatory approvals are based on approvals or clearances from the FDA, any failure to comply with FDA requirements may also disrupt our sales of products in other countries. We cannot assure you that the FDA or other governmental authorities would agree with our interpretation of applicable regulatory requirements or that we or our third‑party suppliers have in all instances fully complied with all applicable requirements. If any of these events occur, our reputation could be harmed, we could lose customers and there could be a material adverse effect on our business, financial condition and results of operations.

If we cannot achieve the required level and quality of production, we may need to outsource production or rely on licensing and other arrangements with third parties who possess sufficient manufacturing facilities and capabilities in compliance with regulatory requirements. Even if we could outsource needed production or enter into licensing or other third‑party arrangements, this could reduce our gross margin and expose us to the risks inherent in relying on others. We also cannot assure you that our suppliers will deliver an adequate supply of required components on a timely basis or that they will adequately comply with the QSR. Failure to obtain these components on a timely basis would disrupt our manufacturing processes and increase our costs, which would harm our operating results.

If we are unable to develop new products or enhance existing products to meet our customers’ needs and compete favorably in the market, we may be unable to attract or retain customers.

Our success depends on the successful development, regulatory clearance or approval, introduction and commercialization of new generations of products, treatment systems, and enhancements to and/or simplification of existing products that will meet our customers’ needs provide novel features and compete favorably in the market. The CyberKnife and TomoTherapy platforms, which are currently our principal products, are technologically complex and must keep pace with, among other things, the products of our competitors and new technologies. We are making significant investments in long‑term growth initiatives. Such initiatives require significant capital commitments, involvement of senior management and other investments on our part, which we may be unable to recover. Our timeline for the development of new products or enhancements may not be achieved and price and profitability targets may not prove feasible. Commercialization of new products may prove challenging, and we may be required to invest more time and money than expected to successfully introduce them. Once introduced, new products may adversely impact orders and sales of our existing products or make them less desirable or even obsolete. Compliance with regulations, competitive alternatives, and shifting market preferences may also impact the successful implementation of new products or enhancements. Our inability to develop, gain regulatory approval for or supply competitive products to the market as quickly and effectively as our competitors could limit market acceptance of our products and reduce our sales.

In addition, we depend on one of our customers for a substantial portion of our revenue, and the loss of, or a significant reduction in orders from our major customer could have a material adverse effect on our revenue and operating results. We had one customer that represented 10% or more of total net revenue for the years ended June 30, 2025 and 2024, respectively. In the future, our major customer may decide not to purchase our products at all, may purchase fewer products than they did in the past, or may defer or cancel purchases or otherwise alter their purchasing patterns.

Our ability to successfully develop and introduce new products, treatment systems and product enhancements and simplifications, and the revenues and costs associated with these efforts, will be affected by our ability to:

Even if customers accept new products or product enhancements, the revenues from these products may not be sufficient to offset the significant costs associated with making them available to customers.

We cannot be sure that we will be able to successfully develop, obtain regulatory approval or clearance for, manufacture or introduce new products, treatment systems or enhancements, the roll‑out of which involves compliance with complex quality assurance processes, including QSR. Failure to obtain regulatory approval or clearance for our products or to complete these processes in a timely and efficient manner could result in delays that could affect our ability to attract and retain customers, or could cause customers to delay or cancel orders, causing our backlog, revenues and operating results to suffer.

If we do not effectively manage our growth, our business may be significantly harmed.

In order to implement our business strategy, we expect continued growth in our infrastructure requirements, particularly as we expand into new and growing markets as well as expand our manufacturing capacities and sales and marketing capabilities. To manage our growth, we must expand our facilities, augment our management, operational and financial systems, hire and train additional qualified personnel, scale‑up our manufacturing capacity and expand our marketing and distribution capabilities. Our manufacturing, assembly and installation process is complex and occurs over many months and we must effectively scale this entire process to satisfy customer expectations and changes in demand. Further, to accommodate our growth and compete effectively, we will be required to make improvements to our business operations. We cannot be certain that our personnel, systems, procedures and internal controls will be adequate to support our future operations and any expansion of our systems and infrastructure may require us to commit significant additional financial, operational and management resources. If we cannot manage our growth effectively, our business will suffer.

We could become subject to product liability claims, product recalls, other field actions and warranty claims that could be expensive, divert management’s attention and harm our business.

Our business exposes us to potential liability risks that are inherent in the manufacturing, marketing, sale, installation, servicing, and support of medical device products. We may be held liable if one of our CyberKnife or TomoTherapy platforms or our software, including the Precision Treatment Planning System with iDMS Data Management System software, causes or contributes to injury or death or is found otherwise unsuitable during usage. Our products incorporate sophisticated components and computer software. Complex software can contain errors, particularly when first introduced. In addition, new products or enhancements may contain undetected errors or performance problems that, despite testing, are discovered only after installation. Because our products are designed to be used to perform complex surgical and therapeutic procedures involving delivery of radiation to the body, defects, even if small, could result in a number of complications, some of which could be serious and could harm or kill patients. Any alleged weaknesses in physician training and services associated with our products may result in unsatisfactory patient outcomes and product liability lawsuits. It is also possible that defects in the design, manufacture or labeling of our products might necessitate a product recall or other field corrective action, which may result in warranty claims beyond our expectations and may harm our reputation and create adverse publicity. A product liability claim, regardless of its merit or eventual outcome, could result in significant legal defense costs that may not be covered by insurance and be time-consuming to defend. We may also be subject to claims for personal injury, property damage or economic loss related to, or resulting from, any errors or defects in our products, or the installation, servicing and support of our products, or any professional services rendered in conjunction with our products. Adverse publicity related to any product liability actions may cause patients to be less receptive to radiation therapy generally or our products specifically and could also result in additional regulation that could adversely affect our ability to promote, manufacture and sell our products. The coverage limits of our insurance policies may not be adequate to cover future claims.

If sales of our products increase or we suffer future product liability claims, we may be unable to maintain product liability insurance in the future at satisfactory rates or with adequate amounts of coverage. A product liability claim, any product recalls or other field actions or excessive warranty claims, whether arising from defects in design or manufacture or labeling, could negatively affect our sales or require a change in the design, manufacturing process or the indications for which our systems or software may be used, any of which could harm our reputation and business and result in a decline in revenue.

In addition, if a product we designed or manufactured is defective, whether because of design or manufacturing, supplied parts, or labeling defects, improper use of the product or other reasons, we may be required to notify regulatory authorities and/or to recall the product, possibly at our expense. We have voluntarily initiated recalls and other product corrections in the past. For example, in fiscal year 2025, we voluntarily initiated one recall related to the couch for the CyberKnife System, which was reported to the FDA. We are committed to the safety and precision of our products and while no serious adverse health consequences have been reported in connection with these recalls and the costs associated with each such recall were not material, we cannot ensure that the FDA will not require that we take additional actions to address problems that resulted in previous recalls or that similar or more significant product recalls will not occur in the future. A required notification of a correction or removal to a regulatory authority or recall could result in an investigation by regulatory authorities of our products, which could in turn result in required recalls, restrictions on the sale of the products or other civil or criminal penalties. The adverse publicity resulting from any of these actions could cause customers to review and potentially terminate their relationships with us. These investigations, corrections or recalls, especially if accompanied by unfavorable publicity, patient injury or termination of customer contracts, could result in incurring substantial costs, losing revenues and damaging our reputation, each of which would harm our business.

Our reliance on single‑source suppliers for critical components of the CyberKnife and TomoTherapy platforms could harm our ability to meet demand for our products in a timely and cost effective manner.

We currently depend on single source suppliers for some of the critical components necessary to assemble the CyberKnife and TomoTherapy platforms, including, with respect to the CyberKnife platform, the robot, couch and magnetron and, with respect to the TomoTherapy platforms, the couch, solid state modulator and magnetron. Global supply chain disruptions in parts of our supply chain, have occurred and could occur again in the future, causing delays in the receipt of certain component parts for our products and increased pricing pressure for such parts, including with respect to parts purchased from our single-source suppliers, adversely affecting our gross margins and increasing the risk that these supply chain disruptions could materially affect our ability to meet customer demand. Furthermore, as a result of the effects of the macroeconomic conditions, including inflation, and supply chain challenges, some of our suppliers have limited or reduced the sale of such components to us or increased the cost of such components to us. If these conditions worsen, or if these suppliers were to experience financial difficulties, additional supply chain or other problems that prevents them from supplying us with the necessary components, we could fail to meet product demand, which could have a material adverse effect on our business, financial condition and results of operations. These sole source and other suppliers could also be subject to quality and performance issues, materials shortages, excess demand, reduction in capacity and other factors that may disrupt the flow of goods to us; thereby adversely affecting our business and customer relationships. If any single‑source supplier was to cease delivering components to us or fail to provide the components to our specifications and on a timely basis, we might be required to find alternative sources for these components. The disruption or termination of the supply of components, including as a result of global shortages in important components, have resulted in, and will continue to cause, inflationary pressure on our supply chain and a significant increase in the costs of these components, which have materially affected and could continue to adversely affect our results of operations. In addition, we expect inflation and the ongoing supply chain challenges and logistics costs to impact our cash from operations through at least calendar year 2025. In some cases, alternative suppliers may be located in the same geographic area as existing suppliers, and are thus subject to the same economic, political and geographic factors that may affect existing suppliers to meet our demand. We may have difficulty or be unable to find alternative sources for these components. Difficulties in obtaining a sufficient supply of component materials could increase as well as the costs associated with such components, and we expect such difficulties to persist through at least calendar year 2025. As a result, we may be unable to meet the demand for the CyberKnife or TomoTherapy platforms, which could harm our ability to generate revenue and damage our reputation. Even if we do find alternate suppliers, we will be required to qualify any such alternate suppliers and we would likely experience a lengthy delay in our manufacturing processes or a cessation in production, which would result in delays of shipment to end users. We cannot assure you that our single‑source suppliers will be able or willing to meet our future demands.

We generally do not maintain large volumes of inventory, which makes us even more susceptible to harm if a single source supplier fails to deliver components on a timely basis or we experience quality issues with the components we do have in inventory, and maintaining our historical levels of inventory has been adversely impacted by the macroeconomic

environment. For example, a supplier quality issue resulted in higher than anticipated failure rates for a component in our platforms, which resulted in higher parts consumption costs that adversely affected our financial results in fiscal year 2024. Furthermore, if we are required to change the manufacturer of a critical component of the CyberKnife or TomoTherapy platforms, we will be required to verify that the new manufacturer maintains facilities, procedures and operations that comply with our quality and applicable regulatory requirements and guidelines, which could further impede our ability to manufacture our products in a timely manner. If the change in manufacturer results in a significant change to the product, a new 510(k) clearance would be necessary, which would likely cause substantial delays. The disruption or termination of the supply of key components for the CyberKnife or TomoTherapy platforms could harm our ability to manufacture our products in a timely manner or within budget, harm our ability to generate revenue, lead to customer dissatisfaction and adversely affect our reputation and results of operations.

Failures of components also affect the reliability and performance of our products, can reduce customer confidence in our products, increase service parts consumption, and may adversely affect our financial performance. From time to time, we may receive components that do not perform according to their specifications, which could result in the inability of such customer utilize our systems in their practices until such components are replaced. Any future difficulty in obtaining reliable component parts could result in increased customer dissatisfaction and adversely affect our reputation, our ability to protect and retain our installed base of customers and results of operations.

We depend on key employees, the loss of whom would adversely affect our business. If we fail to attract and retain employees with the expertise required for our business, we may be unable to continue to grow our business.

We are highly dependent on the members of our senior management, sales, marketing, operations and research and development staff. Our future success will depend in part on our ability to retain our key employees and to identify, hire and retain additional personnel. Competition for qualified personnel in the medical device industry is intense and finding and retaining qualified personnel with experience in our industry is very difficult. We believe there are only a limited number of individuals with the requisite skills to serve in many of our key positions and we face significant competition for key personnel and other employees, from other medical equipment and software manufacturers, technology companies, universities and research institutions. Fluctuations in labor availability globally, including labor shortages and staff burnout and attrition, may also impact our ability to hire and retain personnel critical to our manufacturing, logistics, and commercial operations. In addition, no payments were made under the company bonus plan in fiscal year 2025. As a result, we may not be able to retain our existing employees or hire new employees quickly enough to meet our needs. Moreover, we have from time to time conducted reductions in force in order to optimize our organizational structure and reduce costs, some of which were substantial, and certain senior personnel have also departed for various reasons. At the same time, we may face high turnover among employees that are critical to our ongoing operations, requiring us to expend time and resources, including financial resources, to source, train and integrate new employees. The challenging markets in which we compete for talent may also require us to invest significant amounts of cash and equity to attract and retain employees. In addition, a significant portion of our compensation to our key employees is in the form of stock related grants. A prolonged depression in our stock price could make it difficult for us to retain our key and other employees and recruit additional qualified personnel and we may have to pay additional compensation to employees to incentivize them to join or stay with us. We do not maintain, and do not currently intend to obtain, key employee life insurance on any of our personnel. If we fail to hire and retain key personnel and other employees, we may be unable to continue to grow our business successfully.

Disruption of critical information technology systems, infrastructure and data or cyberattacks or other security breaches or incidents could harm our business and financial condition.

Information technology helps us operate more efficiently, interface with customers, maintain financial accuracy and efficiency and accurately produce our financial statements. If we do not allocate and effectively manage the resources necessary to build, sustain and secure the proper technology infrastructure, we could be subject to transaction errors, processing inefficiencies, the loss of customers, business disruptions or the loss, unavailability of or damage to data and intellectual property through a cyberattack (including ransomware and other attacks) or other security breaches or incidents. While management is committed to identifying cybersecurity risks and working to address them through oversight of data security by our Chief Information Security Officer and implementation of various technical safeguards, procedural requirements and policies, regardless of the resources we allocate and the effectiveness with which we manage them, we face a risk of cyberattacks and other security breaches and incidents. Any cyberattacks or other security breaches or incidents we suffer could expose us to a risk of lost, unavailable, or corrupted information, unauthorized disclosure or other processing of information, claims, litigation and possible liability to employees, customers and others, and investigations and proceedings

by regulatory authorities. Cyberattacks and other means of creating security breaches and incidents or disruptions continue to increase in frequency, sophistication, and intensity and are becoming increasingly difficult to detect on a timely basis or otherwise, especially as they relate to attacks on third-party providers or their vendors. Such attacks are often carried out by motivated and highly skilled actors, who are increasingly well-resourced. Techniques used to compromise or sabotage systems, including the use of advanced technologies, such as machine learning or artificial intelligence ("AI") change frequently, may originate from less regulated and remote areas of the world, may be difficult to detect, and generally are not recognized until after they are launched against a target. As a result, we may be unable to anticipate these techniques or implement adequate preventative measures. Additionally, cyberattack activity may be heightened in connection with geopolitical events such as the Russia-Ukraine and Middle East conflicts. In addition to potential exposure to cyberattacks, security incidents, or other actions that may compromise the security of or interfere with the function of our products, defects or vulnerabilities in the software or systems of our third-party vendors may expose failures in our internal controls and risk management processes, which may adversely impact our business, financial condition, results of operations, or cash flows and may also harm our reputation, brand, and customer relationships.

If our data management systems or those of our third-party providers do not effectively collect, store, process and report relevant data for the operation of our business, whether due to equipment malfunction or constraints, software deficiencies, computer viruses, security breaches or incidents, cyberattacks, catastrophic events or human error, our ability to effectively plan, forecast and execute our business plan and comply with applicable laws and regulations will be impaired, perhaps materially. Any such impairment could materially and adversely affect our financial condition, results of operations, cash flows and the timeliness with which we internally and externally report our operating results. As a result, our information systems require an ongoing commitment of significant resources to maintain, protect, and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving legal and regulatory standards, the increasing need to protect patient and customer information, and the information technology needs associated with our changing products and services. There can be no assurance that our process of consolidating the number of systems we operate, upgrading and expanding our information systems capabilities, continuing our efforts to build security into the design of our products, protecting and enhancing our systems and developing new systems to keep pace with continuing changes in information processing technology will be successful or that additional systems issues will not arise in the future, or that we will not suffer from disruptions or other systems issues even if we devote substantial resources and personnel to these efforts.

In addition, privacy and security breaches and incidents arising from errors, malfeasance or misconduct by employees, contractors or others with permitted access to our systems may pose a risk that sensitive data, including individually identifiable data, may be exposed to unauthorized persons or to the public and may compromise our security systems. There can be no assurance that any efforts we make to prevent against such privacy or security breaches or incidents have been or will be able to prevent breakdowns or breaches or incidents in our systems or those of our third-party service providers that could adversely affect our business. Third parties may also attempt to fraudulently induce employees or customers into disclosing usernames, passwords or other sensitive information, which may in turn be used to access our information technology systems. For example, our employees have received in the past and likely will continue to receive “phishing” e-mails attempting to induce them to divulge sensitive information. We may also face increased cybersecurity risks due to our reliance on internet technology and many of our employees working remotely at least part of the time, which may create additional opportunities for cybercriminals to exploit vulnerabilities. In addition, adversaries might attempt to gain unauthorized access to our products or systems to obtain personal data relating to patients or employees, our confidential or proprietary information or confidential information we hold on behalf of third parties, which, if successful, could pose a risk of loss, unavailability, or corruption of, or unauthorized access to or acquisition of, data, risk to patient safety and risk of product recall. The techniques used to obtain unauthorized access to our systems change frequently and may be difficult to detect, and we may not be able to anticipate and prevent these intrusions or mitigate them when they occur. Third-party service providers store and otherwise process certain personal data and other confidential or proprietary information of ourselves and third parties on our behalf, and these service providers face similar risks. In addition, our employees, third-party service providers, strategic partners, or other contractors or consultants may input personal or confidential information, or other business data of ours, into an AI system (in particular, a system that is managed, owned, or controlled by a third party), which may disrupt and otherwise compromise our business operations, divert the attention of management and key information technology resources, potentially lead to security breaches or incidents or other unauthorized access to, or other use or processing of, personal information, our confidential information or other business data. Moreover, we manufacture and sell hardware and software products that allow our customers to store confidential information about their patients. Both types of products are often connected to and reside within our customers’ information technology infrastructures. We do not have measures to configure or secure our customers’ equipment or any information stored in our customers’ systems or at

their locations, which is the responsibility of our customers. Our customers are also continually updating their cybersecurity standards for the products that they purchase. While we have implemented security measures designed to protect our hardware and software products from unauthorized access and cyberattacks, these measures may not meet the standards set by our customers or be effective in securing these products, particularly since techniques used to obtain unauthorized access, or to sabotage systems, change frequently and may not be recognized until launched against a target. A network security or systems security breach of incident suffered by ourselves or our third-party service providers or other events that cause the loss or unauthorized use or disclosure of, or access by third parties to, sensitive information stored by us or our customers could result in loss, unavailability, or unauthorized acquisition, modification, or other processing of data, and any such events, or the perception that these events have occurred or that our security measures for our products are lacking, could have serious negative consequences for our business, including indemnity obligations, possible fines, penalties and damages, reduced demand for our products and services, an unwillingness of our customers to use our products or services, harm to our reputation and brand, and time consuming and expensive litigation, any of which could have an adverse effect on our business, financial condition, and operating results.

Due to frequently changing attack techniques, along with the increased volume and sophistication of the attacks, including the increasing use of tools and techniques that are designed to circumvent controls, avoid detection, and remove or obfuscate forensic evidence, all of which hinders our ability to identify, investigate, and recover from incidents, we could be adversely impacted by cybersecurity attacks or other security breaches or incidents. This impact could result in reputational, competitive, operational, or other business harm as well as financial costs and claims, demands, litigation and regulatory action.

While we do maintain insurance coverage that is intended to address certain aspects of data security risks, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise.

Any actual or perceived failure by us to comply with legal or regulatory requirements related to privacy, cybersecurity and data protection in one or multiple jurisdictions could result in proceedings, actions or penalties against us.

There are numerous state, federal and foreign laws, regulations, decisions and directives regarding privacy and the collection, storage, transmission, use, processing, disclosure and protection of personal information and other data, the scope of which is continually evolving and subject to differing interpretations. Our worldwide operations mean that we are subject to privacy, cybersecurity and data protection laws and regulations in many jurisdictions to varying degrees, and that some of the data we process, store and transmit may be transmitted across countries. For example, in the U.S., privacy and security rules implementing the Health Insurance Portability and Accountability Act (“HIPAA”) require us as a business associate, in certain instances, to protect the confidentiality of patient health information, and the Federal Trade Commission has consumer protection authority, including with regard to privacy and cybersecurity. In Europe, the GDPR imposes several stringent requirements for controllers and processors of personal data that impose substantial obligations and, in the event of violations, may impose significant fines of up to the greater of 4% of worldwide annual revenue or €20 million. In the UK, the Data Protection Act of 2018 and the UK GDPR collectively implement material provisions of the GDPR and provide for penalties for noncompliance of up to the greater of £17.5 million or four percent of worldwide revenues.

Data transfer and localization requirements also appear to be increasing and becoming more complex. With regard to transfers to the U.S. of personal data from our employees and European customers and users, both the EU-U.S. Privacy Shield and standard contractual clauses issued by the European Commission (the “EU SCCs”) have been subject to legal challenge. In July 2020, the Court of Justice of the European Union (“CJEU”) released a decision in the Schrems II case (Data Protection Commissioner v. Facebook Ireland, Schrems) (the “CJEU Decision”), declaring the EU-U.S. Privacy Shield invalid and imposing additional obligations in connection with the use of the EU SCCs, another mechanism for cross-border personal data transfers from the European Economic Area (“EEA”). Although the EU SCCs remain a valid means to transfer personal data from the EEA, the CJEU imposed additional obligations in connection with their use and, on June 4, 2021, the European Commission issued revised EU SCCs that address certain concerns of the CJEU. The United Kingdom also has issued new standard contractual clauses (the “UK SCCs”) that became effective March 21, 2022, and which are required to be implemented. In March 2022, the EU and U.S. reached an agreement in principle on a new EU-U.S. Data Privacy Framework (“DPF”). In October 2022, the U.S. issued an executive order in furtherance of the DPF, on which basis the European Commission adopted an adequacy decision with respect to the DPF in July 2023, allowing its implementation and availability for companies to use to legitimize transfers of personal data from the E.U. to the U.S. It remains unclear, however, whether this framework will be appropriate for us to rely upon. The DPF has faced a legal challenge and it may be subject to additional challenges. Additionally, the European Commission’s adequacy decision regarding the DPF provides

that the DPF will be subject to future reviews and may be subject to suspension, amendment, repeal, or limitations to its scope by the European Commission. Additionally, the U.S. Department of Justice issued a final rule that took effect in April 2025 and places limitations, and in some cases prohibitions, on certain transfers of sensitive personal data to data to business partners located in China or with other specified links to China and other designated countries (the “DOJ Sensitive Personal Data Transfer Limitations Rule”). These and other developments relating to cross-border data transfer may require us to implement additional contractual and technical safeguards for any personal data transferred out of various jurisdictions, which may increase compliance costs, lead to increased regulatory scrutiny or liability, may require additional contractual negotiations, and may adversely impact our business, financial condition and operating results.

Other jurisdictions have adopted laws and regulations addressing privacy, data protection, data security, or other aspects of data processing, such as data localization. For example, the People’s Republic of China (“PRC”) and Russia have passed laws that require individually identifiable data on their citizens to be maintained on local servers and that may restrict transfer or processing of that data if certain data quantity thresholds are triggered. Additionally, the Personal Information Protection Law (“PIPL”) of the PRC went into effect on November 1, 2021. The PIPL shares similarities with the GDPR, including extraterritorial application, data minimization, data localization, and purpose limitation requirements, and obligations to provide certain notices and rights to citizens of the PRC. The PIPL allows for fines of up to 50 million Renminbi or 5% of a covered company’s revenue in the prior year. We may be required to modify our policies, procedures, and data processing measures in order to address requirements under these or other privacy, data protection, or cybersecurity regimes, and may face claims, litigation, investigations, or other proceedings regarding them and may incur related liabilities, expenses, costs, and operational losses.

Further, the U.S. government has undertaken an evaluation of national security concerns and other risks relating to the transfer of personally identifiable information from the United States to China, and on June 9, 2021, U.S. President Biden signed an executive order instituting a framework for determining national security risks of transactions that involve applications connected to governments or militaries of certain foreign adversaries or that collect sensitive personal data from U.S. consumers, with the DOJ Sensitive Personal Data Transfer Limitations Rule issued in April 2025. In 2019, an executive order citing national security risks in the telecommunications sector served to block U.S. companies from buying Chinese-made Huawei and ZTE products. If our operations, including those involving the processing of U.S.-collected data such as medical imagery, through the JV in China, come to be perceived as a U.S. national security risk, those operations may become subject to executive orders, sanctions, or other measures. The DOJ Sensitive Personal Data Transfer Limitations Rule, and any other ban or other restriction on our transfer of data to the JV in China, may increase costs as we seek operational and data processing alternatives.

New and proposed privacy, cybersecurity, and data protection laws are also providing new rights to individuals and increasing the penalties associated with non-compliance. For example, the California Consumer Privacy Act (the “CCPA”), which became effective on January 1, 2020, imposes stringent data privacy and data protection requirements regarding the personal information of California residents, and provides for penalties for noncompliance of up to $7,500 per violation, as well as a private right of action from individuals in relation to certain security breaches.

The California Privacy Rights Act (“CPRA”), approved by California voters in November 2020, became effective on January 1, 2023. The CPRA, significantly modified the CCPA, has resulted in further uncertainty and may require us to incur additional costs and expenses in an effort to comply. We will continue to monitor developments related to the CPRA and anticipate additional costs and expenses associated with CPRA compliance. The enactment of the CCPA, as modified by the CPRA, is prompting a wave of similar legislative developments in other states in the U.S., which could potentially create a patchwork of overlapping but different state laws. For example, Virginia, Colorado, Utah, and Connecticut all have enacted state laws that became effective in 2023; Texas, Montana, Oregon, and Florida have adopted laws that became effective in 2024, Delaware, Iowa, Maryland, Minnesota, Nebraska, New Hampshire, New Jersey and Tennessee have adopted laws that have become or will become effective in 2025; and Indiana, Kentucky, and Rhode Island have adopted laws that will become effective in 2026. These new state laws share similarities with the CCPA, CPRA, and legislation proposed in other states. Other states have enacted other types of privacy legislation, such as Washington’s My Health, My Data Act, which includes a private right of action. Additionally, the U.S. federal government is contemplating privacy legislation. We cannot fully predict the impact of the CCPA, CPRA, or other new or proposed legislation on our business or operations, but the restrictions imposed by these laws and regulations may require us to modify our data handling practices and impose additional costs and burdens, including risks of regulatory fines, litigation and associated reputational harm. In addition, U.S. and international laws that have been applied to protect consumer privacy (including laws regarding unfair and deceptive practices in the U.S. and GDPR in the EU) may be subject to evolving interpretations or applications in light of privacy

developments. As a result, we may be subject to significant consequences, including penalties and fines, for any failure to comply with such laws, regulations and directives.

Privacy, cybersecurity and data protection legislation around the world is comprehensive and complex and there has been a trend towards more stringent enforcement of requirements regarding protection and confidentiality of personal data. The restrictions imposed by such laws and regulations may limit the use and adoption of our products and services, reduce overall demand for our products and services, require us to modify our data handling practices and impose additional costs and burdens. With increasing enforcement of privacy, cybersecurity and data protection laws and regulations, there is no guarantee that we will not be subject to investigation, enforcement actions or other proceedings by governmental bodies or that our costs relating to privacy, data protection or cybersecurity laws and regulations will not increase significantly. Enforcement actions, investigations and other proceedings can be costly, require significant time and attention of management and other personnel and interrupt regular operations of our business. In addition, there has been a developing trend of civil lawsuits and class actions relating to breaches of consumer data held by large companies. While we have not been named in any such suits, we may be in the future, including if we were to suffer a security breach or incident. Any inability to adequately address concerns relating to privacy, data protection or cybersecurity, even if unfounded, or to comply with applicable laws, regulations, policies, industry standards, contractual obligations or other legal obligations could result in additional cost and liability to us, damage our reputation, inhibit sales and adversely affect our business. Our actual or alleged failure to comply with applicable laws and regulations could result in investigation, enforcement actions or other proceedings against us, including fines and public censure, claims for damages by customers and other affected individuals, damage to our reputation and loss of goodwill (both in relation to existing customers and prospective customers), any of which could harm our business, results of operations and financial condition.

We have incorporated and continue to work to further incorporate artificial intelligence into our products, services, and internal operations. Implementation of artificial intelligence and machine learning technologies may result in legal and regulatory risks, reputational harm, or other adverse consequences to our business.

We have integrated AI, including machine learning, in certain of our products, services and internal operations. Some of the uses in our internal operations include using AI to help detect and respond to abnormalities that could indicate a part is about to break, provide our service engineers support on information about parts, analyzing datasets, creating documents for internal purposes, and develop processes for internal departments to manage internal workflows. Further, certain of our third-party vendors utilize AI and machine learning technologies in furnishing services to us. As with many technological innovations, AI presents risks and challenges that could affect its adoption, and therefore our business. Our products utilize, and we plan to further examine, develop and introduce, machine learning algorithms, predictive analytics, and other AI technologies to offer new or upgraded solutions and enhance our capabilities. If these AI or machine learning models are incorrectly designed, the performance of our products, services, and business, as well as our reputation, could suffer or we could incur liability through the violation of laws or contracts to which we are a party. Additionally, new and evolving laws and regulations related to the development and use of AI and machine learning technologies have been proposed, and in certain cases enacted, in various jurisdictions, including the United States, and the EU has adopted an AI Act that adopts an overall regulatory framework for AI. These laws and regulations may impose onerous obligations and may require us to unexpectedly rework or reevaluate improvements to be compliant. Use of AI technologies may expose us to an increased risk of regulatory enforcement and litigation. Moreover, some of the AI features involve the processing of personal data and may be subject to laws, policies, legal obligations, and codes of conduct related to privacy and data protection.

Though we have taken steps to be thoughtful in our development, training, and implementation of AI, it could pose certain risks to our customers, including patients, clinicians, and healthcare institutions, and it is not guaranteed that regulators will agree with our approach to limiting these risks or to our compliance more generally. Risks can include, but are not limited to, the potential for errors or inaccuracies in the algorithms or models used by AI, the potential for bias or inaccuracies in the data used to train the AI, the potential for improper processing of personal information, and the potential for cybersecurity breaches that could compromise patient data or product functionality. Such risks could negatively affect the performance of

our products, services, and business, as well as our reputation and the reputations of our customers, and we could incur liability through the violation of laws or contracts to which we are a party or civil claims.

Continued consolidation in the healthcare industry could have an adverse effect on our business, financial condition, or results of operations.

The healthcare industry has been consolidating, and organizations continue to consolidate purchasing decisions for many of our customers, particularly in the United States. Numerous initiatives and reforms by legislators, regulators, and third-party payors to curb the rising cost of healthcare have catalyzed a consolidation of aggregate purchasing power within the markets in which we sell our products. As the healthcare industry consolidates, competition to provide products and services is expected to continue to intensify, resulting in pricing pressures and decreased average selling prices. In addition, for smaller hospitals or groups that do not consolidate with larger networks, these entities may face increasing cost and/or competitive pressures, which could impact their ability to purchase additional products and services from us or make contractual payments over time. We expect that market demand, government regulation, third-party payor coverage and reimbursement policies, government contracting requirements, new entrants, technology, and societal pressures will continue to change the worldwide healthcare industry, resulting in further consolidation, which may exert further downward pressure on prices of our products and services and may have a material adverse impact on our business, financial condition, or results of operations.

If third‑party payors do not provide sufficient coverage and reimbursement to healthcare providers for use of the CyberKnife and TomoTherapy platforms or if the number of patients covered by health insurance reduces, demand for our products and our revenue could be adversely affected.

Our customers rely significantly on reimbursement from public and private third-party payors for CyberKnife and TomoTherapy platform procedures. Our ability to commercialize our products successfully and increase market acceptance of our products will depend in significant part on the extent to which public and private third-party payors provide adequate coverage and reimbursement for procedures that are performed with our products and the extent to which patients that are treated by our products continue to be covered by health insurance. Third-party payors may establish or change the reimbursement for medical products and services that could significantly influence the purchase of medical products and services. If reimbursement policies or other cost containment measures are instituted in a manner that significantly reduces the coverage or payment for the procedures that are performed with our products or if there is a prolonged reduction in the number of patients eligible to be treated by our products that are covered by health insurance, our revenue may decline, our existing customers may not continue using our products or may decrease their use of our products, and we may have difficulty obtaining new customers. Such actions would likely have a material adverse effect on our operating results.

In addition, the Centers for Medicare and Medicaid Services (“CMS”) reviews reimbursement rates annually and may implement significant changes in future years, which could discourage existing and potential customers from purchasing or using our products. Further, outside of the U.S., reimbursement practices vary significantly by country. Market acceptance of our products may depend on the availability and level of coverage and reimbursement in any country within a particular time.

The safety and efficacy of our products for certain uses is not yet supported by long‑term clinical data, and our products may therefore prove to be less safe and effective than initially thought.

Although we believe that the CyberKnife and TomoTherapy platforms have advantages over competing products and technologies, we do not have sufficient clinical data demonstrating these advantages for all tumor indications. In addition, we have only limited five‑year patient survival rate data, which is a common long‑term measure of clinical effectiveness in cancer treatment. We also have limited clinical data directly comparing the effectiveness of the CyberKnife platform to other competing platforms. Future patient studies or clinical experience may indicate that treatment with the CyberKnife platform does not improve patient survival or outcomes relative to other platforms.

Likewise, because the TomoTherapy platform has only been on the market since 2003, we have limited complication or patient survival rate data with respect to treatment using the systems for all clinical indications. If future patient studies or clinical experience do not support our beliefs that the TomoTherapy platform offer a more advantageous treatment for a wide variety of cancer types, use of the systems could fail to increase or could decrease, and our business would therefore be adversely affected.

Such results could reduce the rate of reimbursement by both public and private third‑party payors for procedures that are performed with our products, slow the adoption of our products by physicians, significantly reduce our ability to achieve expected revenues and could prevent us from being profitable. In addition, if future results and experience indicate that our products cause unexpected or serious complications or other unforeseen negative effects, the FDA could rescind our clearances, our reputation with physicians, patients and others may suffer and we could be subject to significant legal liability.

We rely on third parties to perform shipping and logistics functions on our behalf. Failures or disruptions at our logistics providers have occurred and could occur in the future, which could adversely impact our business.

Customer service is a critical element of our sales strategy. Third party logistics providers store most of our spare parts inventory in depots around the world and perform a significant portion of our spare parts logistics and shipping activities. Our logistics providers may terminate their relationship with us, suffer an interruption in their business, including as a result of macroeconomic factors, significantly increase fees for services or experience delays, disruptions or quality control problems in their operations, or we may have to change and qualify alternative logistics providers for our spare parts. For example, in recent years, we have experienced delays in shipment of parts to customers as well as increased freight and logistics expenses due to macroeconomic factors and these impacts could intensify. These delays and increased costs have adversely affected our gross margins and net income (loss) and we currently expect such delays and increased costs to continue through at least calendar year 2025, and potentially longer. If this continues for longer than we expect or if any of the above occurs our customers may experience further delays and higher costs and our reputation, business, financial condition and results of operations, including our ability to recognize revenue, may be adversely affected.

Third parties may claim we are infringing their intellectual property or that we are operating outside the scope of or violating a license or other agreement relating to their intellectual property, and we could suffer significant audit, litigation or licensing expenses, incur liabilities associated with indemnification obligations to customers, experience disruptions in the supply of components of our products or related services, or be prevented from selling our product or components of our product.

The medical device industry is characterized by a substantial amount of litigation over patent and other intellectual property rights. In particular, the field of radiation treatment of cancer is well established and crowded with the intellectual property of competitors and others. We also expect that other participants will enter the field. A number of companies in our market, as well as universities and research institutions, have issued patents and have filed patent applications that relate to the use of radiation therapy and stereotactic radiosurgery to treat cancerous and benign tumors.

Determining whether a product infringes a patent involves complex legal and factual issues, and the outcome of patent litigation actions is often uncertain. We have not conducted an extensive search of patents issued to third parties, and no assurance can be given that third‑party patents containing claims covering our products, parts of our products, technology or methods do not exist, have not been filed, or could not be filed or issued. Because of the number of patents issued and patent applications filed in our technical areas or fields, our competitors or other third parties may assert that our products and the methods we employ in the use of our products are covered by U.S. or foreign patents held by them.

In addition, because patent applications can take many years to issue and because publication schedules for pending applications vary by jurisdiction, there may be applications now pending of which we are unaware, and which may result in issued patents that our current or future products infringe. Also, because the claims of published patent applications can change between publication and patent grant, there may be published patent applications that may ultimately issue with claims that we infringe. There could also be existing patents that one or more of our products or parts may infringe and of which we are unaware. As the number of competitors in the market for less invasive cancer treatment alternatives grows, and as the number of patents issued in this area grows, the possibility of patent infringement claims against us increases. Regardless of the merit of infringement claims, they can be time‑consuming and result in costly litigation and diversion of technical and management personnel. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise funds, if necessary, to continue our operations.

Also, because we purchase major components and software for each of our products from third party suppliers and manufacturers, we face the additional risk that infringement claims may be brought against us based on patents and other

intellectual property rights that are embodied or contained in, or practiced by, those components (including software components) that we obtain from third parties, and any such claims against us, such as by our direct and indirect suppliers, may additionally allege that we are operating outside the scope of or violating a license or other agreement relating to their intellectual property. These third party suppliers or manufacturers may terminate their licenses with us for a variety of reasons, including actual or perceived failures or breaches of contractual commitments, or they may choose not to renew their licenses with us. The loss of, or inability to obtain, certain third-party licenses or other rights, including the right to resell, or to obtain such licenses or rights on favorable terms, or the need to engage in litigation regarding these matters, could affect the operability or performance of our products until equivalent technology can be identified, licensed or developed, if at all, and integrated into our products, and it may have a material adverse effect on our business, financial condition, and results of operations.

In the event that we become subject to a patent infringement or other intellectual property lawsuit and if the relevant patents or other intellectual property were upheld as valid and enforceable and we were found to infringe or violate the terms of a license or other agreement to which we are a party, we could be subject to third-party audit, experience disruptions in the supply of third-party components or related services, or be prevented from selling our products (or components of our products) unless we obtain a license or are able to redesign the product to avoid infringement. Required licenses may not be made available to us on acceptable terms or at all. If we are unable to obtain a license or successfully redesign our system, we might be prevented from selling such system. If there is an allegation or determination that we have infringed the intellectual property rights of a competitor or other person, we may be required to pay damages, pay ongoing royalties or otherwise settle such matter upon terms that are unfavorable to us. In these circumstances, we may be unable to sell our products at competitive prices or at all, and our business and operating results could be harmed.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the medical device industry, we employ individuals who were previously employed at other medical equipment or biotechnology companies, including our competitors or potential competitors. We may be subject to claims that we or those employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against claims of this nature, litigation could result in substantial costs and be a distraction to management.

It is difficult and costly to protect our intellectual property and our proprietary technologies and we may not be able to ensure their protection.

Our success depends significantly on our ability to obtain, maintain and protect our proprietary rights to the technologies used in our products. Patents and other proprietary rights provide uncertain protections, and we may be unable to protect our intellectual property. For example, we may be unsuccessful in defending our patents and other proprietary rights against third‑party challenges. As key patents expire, our ability to prevent competitors from copying our technology may be limited. In addition, patent reform legislation or precedent could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

In addition to patents, we rely on a combination of trade secrets, copyright and trademark laws, nondisclosure agreements and other contractual provisions and technical security measures to protect our intellectual property rights. These measures may not be adequate to safeguard the technology underlying our products, including in case of a security breach involving our intellectual property. If these measures do not protect our rights adequately, third parties could use our technology, and our ability to compete in the market would be reduced. Although we have attempted to obtain patent coverage for our technology where available and appropriate, there are aspects of the technology for which patent coverage was never sought or never received. There also may be countries in which we sell or intend to sell the CyberKnife or TomoTherapy platforms but have no patents or pending patent applications. Our ability to prevent others from making or selling duplicate or similar technologies will be impaired in those countries in which we have no patent protection. Although we have several issued patents in the U.S. and in foreign countries protecting aspects of the CyberKnife and TomoTherapy platforms, our pending U.S. and foreign patent applications may not issue, may issue only with limited coverage or may issue and be subsequently successfully challenged by others and held invalid or unenforceable. In addition, many countries limit the enforceability of patents against certain third parties, including government agencies or government contractors. In these countries, patents

may provide limited or no benefit. Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time consuming process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we will not have the benefit of patent protection in such countries.

Similarly, our issued patents and those of our licensors may not provide us with any competitive advantages. Competitors may be able to design around our patents or develop products which provide outcomes comparable or superior to ours. Our patents may be held invalid or unenforceable as a result of legal challenges by third parties, and others may challenge the inventorship or ownership of our patents and pending patent applications. In addition, the laws of some foreign countries, such as China where the JV operates, may not protect our intellectual property rights to the same extent as do the laws of the United States and, even if they do, uneven enforcement and procedural barriers may exist in such countries. In the event a competitor or other third party infringes upon our patent or other intellectual property rights or otherwise misappropriates such rights, enforcing those rights may be difficult and time consuming. Even if successful, litigation to enforce our intellectual property rights or to defend our patents against challenge could be expensive and time consuming and could divert our management’s attention from our core business. Damage awards resulting from successful litigation in foreign jurisdictions may not be in amounts commensurate with damage awards in the U.S. We may not have sufficient resources to enforce our intellectual property rights or to defend our patents against a challenge. In addition, we may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially valuable. Litigation also puts our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing. Additionally, we may provoke third parties to assert claims against us.

We also license patent and other proprietary rights to aspects of our technology to third parties in fields where we currently do not operate as well as in fields where we currently do operate. Disputes with our licensees may arise regarding the scope and content of these licenses. Further, our ability to expand into additional fields with our technologies may be restricted by our existing licenses or licenses we may grant to third parties in the future.

Additionally, we have written agreements with collaborators regarding the ownership of intellectual property arising from our collaborations. These agreements generally provide that we must negotiate certain commercial rights with collaborators with respect to joint inventions or inventions made by our collaborators that arise from the results of the collaboration. In some instances, there may not be adequate written provisions to address clearly the resolution of intellectual property rights that may arise from a collaboration. If we cannot successfully negotiate sufficient ownership and commercial rights to the inventions that result from our use of a third-party collaborator’s materials where required, or if disputes otherwise arise with respect to the intellectual property developed with the use of a collaborator’s technology, we may be limited in our ability to utilize these intellectual property rights. In addition, we may face claims by third parties that our agreements with employees, contractors or consultants obligating them to assign intellectual property to us are ineffective or in conflict with prior or competing contractual obligations of assignment, which could result in ownership disputes regarding intellectual property we have developed or will develop and interfere with our ability to capture the commercial value of such intellectual property. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property or may lose our exclusive rights in that intellectual property. Either outcome could harm our business.

The policies and procedures we have in place to protect our trade secrets may not be effective in preventing misappropriation of our trade secrets by others. In addition, confidentiality agreements executed by our employees, consultants and advisors may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure. Litigating a trade secret claim is expensive and time consuming, and the outcome is unpredictable. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge methods and know‑how. If we are unable to protect our intellectual property rights, we may be unable to prevent competitors from using our own inventions and intellectual property to compete against us and our business may be harmed.

Unfavorable results of legal proceedings could materially and adversely affect our financial condition.

We are and may become a party to legal proceedings, claims, investigations, demands and other legal matters in the ordinary course of business or otherwise including intellectual property, product liability, employment, class action, whistleblower and other litigation claims, and governmental and other regulatory investigations and proceedings. These legal proceedings, claims and other legal matters, regardless of merit, may be costly, time‑consuming and require the attention of key management and other personnel. The outcomes of such matters are uncertain and difficult to predict. If any such matters

are adjudicated against us, in whole or in part, we may be subject to substantial monetary damages, disgorgement of profits and injunctions that prevent us from operating our business, any of which could materially and adversely affect our business and financial condition. We cannot guarantee that our insurance coverage will be sufficient to cover any damages awarded against us. Further, legal proceedings, and any adverse resolution thereof, can result in adverse publicity and damage to our reputation, which could adversely impact our business.

Because the majority of our product revenue is derived from sales of the CyberKnife and TomoTherapy platforms, which have a long and variable sales and installation cycle, our revenues and cash flows may be volatile and difficult to predict.

Our primary products are the CyberKnife and TomoTherapy platforms. We expect to generate substantially all of our revenue for the foreseeable future from sales of and service contracts for the CyberKnife and TomoTherapy platforms. The CyberKnife and TomoTherapy platforms have lengthy sales and purchase order cycles because they are major capital equipment items and require the approval of senior management at purchasing institutions. In addition, sales to some of our customers are subject to competitive bidding or public tender processes. These approval and bidding processes can be lengthy. Selling our systems, from first contact with a potential customer to a complete order, generally spans six months to 30 months and involves personnel with multiple skills. The sales process in the U.S. typically begins with pre‑selling activity followed by sales presentations and other sales related activities. After the customer has expressed an intention to purchase a CyberKnife or TomoTherapy platform, we negotiate and enter into a definitive purchase contract with the customer. The negotiation of terms that are not standard for Accuray typically requires additional time and approvals. Typically, following the execution of the contract, the customer begins the building or renovation of a radiation‑shielded facility to house the CyberKnife or TomoTherapy platform, which together with the subsequent installation of the CyberKnife or TomoTherapy platform, can take up to 24 months to complete. In order to construct this facility, the customer must typically obtain radiation device installation permits, which are granted by state and local government bodies, each of which may have different criteria for permit issuance. If a permit was denied for installation at a specific hospital or treatment center, our CyberKnife or TomoTherapy platform could not be installed at that location. In addition, some of our customers are cancer centers or facilities that are new, and in these cases, it may be necessary for the entire facility to be completed before the CyberKnife or TomoTherapy platform can be installed, which can result in additional construction and installation delays. Our sales and installations of CyberKnife and TomoTherapy platforms tend to be heaviest during the third month of each fiscal quarter.

Under our revenue recognition policy, we recognize revenue attributable to a CyberKnife or TomoTherapy platform and related upgrades when control of a platform or upgrade is transferred, which generally happens when a system or upgrade is shipped, while an element of installation is deferred until performed. Events beyond our control may delay shipment or installation and the satisfaction of contingencies required to receive cash inflows and recognition of revenue associated with shipment or installation. Such events may include a delay in the construction at the customer site or customer delay in obtaining receipt of regulatory approvals such as certificates of need. In addition, disruption in operations of certain customers macroeconomic factors have resulted in delays in construction, shipment or installation and some have failed to timely pay their obligations when due. For example, reduced budgets and lower capital deployment priority for radiotherapy equipment, along with longer customer installation timelines, in the United States have negatively impacted our net revenue since fiscal year 2024, and we expect this will continue to have an impact through fiscal year 2026. If the events which are beyond our control delay the customer from obtaining funding or financing of the entire transaction, we may not be able to recognize revenue for the sale of the entire system because the collectability of contract consideration is not reasonably assured.

The long sales cycle, together with delays in the shipment of CyberKnife and TomoTherapy platforms or customer cancellations that could affect our ability to recognize revenue, could adversely affect our cash flows and revenue, which would harm our results of operations and may result in significant fluctuations in our reporting of quarterly revenues. Our historical experience indicates that some of our customers will cancel or renegotiate contracts as economic conditions change or when product offerings change during the long sales cycle. We anticipate a portion of our open contracts may never result in revenue recognition primarily due to the long sales cycle and factors outside of our control including changes in customers' needs or financial condition, changes in government or health insurance reimbursement policies or changes to regulatory requirements. As a result of these fluctuations, it is likely that in some future quarters, our operating results will fall below the expectations of securities analysts or investors. If that happens, the market price of our stock would likely decrease. These fluctuations also mean that you will not be able to rely upon our operating results in any particular period as an indication of future performance.

We depend on third‑party distributors to market and distribute our products in international markets. If our distributors fail to successfully market and distribute our products, our business will be materially harmed.

We have strategic relationships with a number of key distributors for sales and service of our products in certain foreign countries, including the JV in China and other third-party distributors in other regions, including Europe, Russia, the Middle East, Africa, the Asia Pacific region, and Latin America. Many of the countries in these regions are not highly developed at this time and therefore, sales opportunities may be limited. We cannot control the efforts and resources our third party distributors will devote to marketing the CyberKnife or TomoTherapy platforms. Our distributors may not be able to successfully market and sell the CyberKnife or TomoTherapy platforms, may not devote sufficient time and resources to support the marketing and selling efforts and may not market the CyberKnife or TomoTherapy platform at prices that will permit the product to develop, achieve or sustain market acceptance. In some jurisdictions, we rely on our distributors to manage the regulatory process and oversee their activities such that they are in compliance with all laws that govern their activities, such as the U.S. Foreign Corrupt Practices Act (“FCPA”), and we are dependent on their ability to do so effectively. If a distributor is terminated by us or goes out of business, it may take us a period of time to locate an alternative distributor, to seek appropriate regulatory approvals and to train its personnel to market the CyberKnife or TomoTherapy platforms, and our ability to sell and service the CyberKnife or TomoTherapy platforms in the region formerly serviced by such terminated distributor could be materially and adversely affected. Any of our distributors could become insolvent or otherwise become unable to pay amounts owed to us when due. If any of these distributor relationships end and are not replaced, our revenues from product sales or the ability to service our products in the territories serviced by these distributors could be adversely affected. Any of these factors could materially and adversely affect our revenue from international markets, increase our costs in those markets or damage our reputation. If we are unable to attract additional international distributors, our international revenue may not grow. If our distributors experience difficulties, do not comply with regulatory or legal requirements that results in fines or penalties, do not actively market the CyberKnife or TomoTherapy platforms or do not otherwise perform under our distribution agreements, our potential for revenue from international markets may be dramatically reduced, and our business could be harmed.

The high unit price of the CyberKnife and TomoTherapy platforms, as well as other factors, may contribute to substantial fluctuations in our operating results, which could adversely affect our stock price.

Because of the high unit price of the CyberKnife and TomoTherapy platforms and the relatively small number of units shipped each quarter, each shipment of a CyberKnife or TomoTherapy platform can represent a significant percentage of our revenue for a particular quarter. Therefore, if we do not ship a CyberKnife or TomoTherapy platform when anticipated, we will not be able to recognize the associated revenue and our operating results will vary significantly from our expectations. This is of particular concern when the economic environment is volatile, such as the current economic environment. For example, during periods of severe economic volatility, such as during the COVID-19 pandemic, we have had customers cancel or postpone orders for our CyberKnife and TomoTherapy platforms and delaying any required build‑outs. These fluctuations and other potential fluctuations mean that you should not rely upon our operating results in any particular period as an indication of future performance.

As a strategy to assist our sales efforts, we may offer extended payment terms, which may potentially result in higher days sales outstanding, reduced cash flows in a particular period and greater payment defaults.

We offer longer or extended payment terms for qualified customers in some circumstances. As of June 30, 2025, customer contracts with extended payment terms of more than one year amounted to approximately 4% of our total accounts receivable balance. While we qualify customers to whom we offer longer or extended payment terms, their financial positions may change adversely over the longer time period given for payment. This may result in an increase in payment defaults, which would negatively affect our revenue. In addition, any increase in days sales outstanding could also negatively affect our cash flow.

We have entered into certain relationships with collaborators, partnerships, strategic alliances, joint venture partners and other third parties, which are outside of our full control and may harm our existing business if we fail to realize the expected benefits of such relationships.

We are a part of certain collaborations, partnerships, strategic alliances, joint ventures and other third-party relationships and depend in part on them to grow our business and market share. Reliance on these third parties subjects us to a number of risks, including that:

As a result of these and other factors, we may not realize the expected benefits of any collaboration, partnership, strategic alliance or joint venture or such benefits may not be realized at expected levels or within the expected time period.

We may attempt to acquire new businesses, products or technologies, including forming joint ventures, and if we are unable to successfully complete these acquisitions or to integrate acquired businesses, products, technologies or employees, we may fail to realize expected benefits or harm our existing business.

Our success will depend, in part, on our ability to expand our product offerings and grow our business in response to changing technologies, customer demands and competitive pressures. In some circumstances, we may determine to do so through the acquisition of complementary businesses, products or technologies rather than through internal development. The identification of suitable acquisition candidates can be difficult, time consuming, and costly, and we may not be able to successfully complete identified acquisitions. Other companies may compete with us for these strategic opportunities. In addition, even if we successfully complete an acquisition, we may not be able to successfully integrate newly acquired organizations, products or technologies into our operations or timely and effectively commence operations because the process of integration could be expensive, time consuming and may strain our resources. Furthermore, the products and technologies that we acquire may not be successful or may require significantly greater resources and investments than we originally anticipated. Implementing or acquiring new lines of business or offering new products and services within existing lines of business can affect the sales and profitability of existing lines of business or products and services, including as a result of sales channel conflicts. With respect to any acquisition, we may be unable to retain employees of acquired companies, or retain the acquired company’s customers, suppliers, distributors or other partners who are our competitors or who have close relationships with our competitors. Future acquisitions could also result in potentially dilutive issuances of equity securities or the incurrence of debt, contingent liabilities, or expenses or other charges, any of which could harm our business and affect our financial results or cause a reduction in the price of our common stock. Further, acquisition targets may also operate in foreign jurisdictions with laws and regulations with which we have limited familiarity, which could adversely impact our ability to comply with such laws and regulations and may lead to increased litigation risk. Such laws may also offer us inadequate or less intellectual property protection relative to U.S. laws, which may impact our ability, as well as the ability of the acquisition target to safeguard our respective intellectual property from infringement and misappropriation. As a result of these and other factors, we may not realize the expected benefits of any acquisition or such benefits may not be realized at expected levels or within the expected time period. The failure to successfully consummate such strategic transactions and effectively integrate and execute following such consummation may have an adverse impact on our growth, profitability, financial position and results of operations.

We previously identified material weaknesses in our system of internal controls as of June 30, 2024. Although such material weaknesses have been remediated, if we fail to maintain an effective system of internal control over financial reporting, our ability to produce timely and accurate financial results could be adversely impacted. As a result, current and potential stockholders could lose confidence in our financial reporting, which could have an adverse effect on our business and our stock price.

Effective internal controls are necessary for us to provide reliable financial reports and to protect from fraudulent, illegal, or unauthorized transactions. If we cannot maintain effective controls and provide timely and reliable financial reports, our business and operating results could be harmed. In the course of preparing the audited consolidated financial statements for the Company’s Annual Report on Form 10-K for the year ended June 30, 2024, the Company concluded that as of June 30, 2024, its internal control over financial reporting was not effective as a result of two material weaknesses at the control activity level related to ensuring all manual journal entries consistently enforced segregation of duties in the approval process and ensuring that the existence of inventory at manufacturing warehouse locations was accurate. These material weaknesses were specifically related to the implementation of the Company’s new ERP system in August 2023 and did not result in any material identified misstatements to the consolidated financial statements, and there were no changes to previously issued financial results. Management also concluded that the Company's disclosure controls and procedures were not effective as of June 30, 2024, September 30, 2024, and December 31, 2024 due to the material weaknesses. For a discussion of

management’s considerations of the Company’s disclosure controls and procedures, internal control over financial reporting, and the material weaknesses identified, refer to Controls and Procedures in Part I, Item 4.

Although the material weaknesses have both been remediated as of March 31, 2025, these remediation efforts have been time consuming and costly and may continue to incur additional time and expense. We may not be able to identify and remediate additional control deficiencies, including material weaknesses, in the future. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to prevent or avoid potential future material weaknesses. Our management may also be unable to conclude in future periods that our disclosure controls and procedures are effective due to the effects of various factors, which may, in part, include unremediated material weaknesses in internal control over financial reporting. Any further disruptions or difficulties that may occur in connection with our ERP system or other systems (whether in connection with the regular operation, periodic enhancements, modifications or upgrades of such systems or the integration of any acquired businesses into such systems, or due to cybersecurity events such as ransomware attacks) could adversely impact the effectiveness of our internal control over financial reporting as well as affect our ability to manufacture products, process orders, deliver products, provide customer support, fulfill contractual obligations, track inventories, or otherwise operate our business, in particular as a result of our limited experience implementing such systems and the complex nature of the system itself. Any failure to establish and maintain effective disclosure controls and procedures and internal control over financial reporting, including due to a failure to remediate the material weaknesses mentioned above or the discovery or occurrence of any additional material weaknesses in our internal control over financial reporting in the future, could adversely affect our ability to prepare financial statements within required time periods and record, process and report financial information accurately, which could result in material misstatements in our financial statements and cause us to fail to meet our reporting and financial obligations, negatively impact the price of our common stock, limit our liquidity and access to capital markets, adversely affect our business, harm our reputation or subject us to litigation or investigations requiring management resources and payment of legal and other expenses.

In addition, it may be difficult to timely determine the effectiveness of our financial reporting systems and internal controls in the future because of the complexity of our financial model. We recognize revenue from a range of transactions including CyberKnife and TomoTherapy platform sales and services. The CyberKnife and TomoTherapy platforms are complex products that contain both hardware and software elements. The complexity of the CyberKnife and TomoTherapy platforms and of our financial model used to recognize revenue on such systems requires us to process a greater variety of financial transactions than would be required by a company with a less complex financial model. Accordingly, efforts to timely remediate deficiencies or weaknesses in our internal controls would likely be more challenging for us than they would for a company with a less complex financial model. Furthermore, if we were to find an internal control deficiency or material weakness, we may be required to amend or restate historical financial statements, which would likely have a negative impact on our stock price.

Additionally, our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

Our ability to raise capital or obtain financing in the future may be limited, and our failure to raise capital when needed could prevent us from executing our growth strategy.

While we believe that our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs for at least the next twelve months, the timing and amount of our working capital and capital expenditure requirements may vary significantly depending on numerous factors, including the other risk factors described above and below.

If our capital resources are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity securities or debt securities or obtain other debt financing, which could be difficult or impossible depending on the state of economic and capital markets environments at the time, as well as the state of our business, operating results and financial condition. For example, any sustained disruption in the capital markets from the global economic environment could negatively impact our ability to raise capital. Our ability to raise additional capital or access capital can be affected by macroeconomic events which affect the economy and the financial and banking sectors in particular. Failures at banks and other financial institutions, or issues in the broader U.S. financial system, including uncertainty related to the debt ceiling,

increased interest rates, and lack of availability of credit, which may have an impact on the broader capital markets and, in turn, our ability to access those markets. In addition, the tightening of the credit markets and lending standards could it make more difficult to raise capital through either debt or equity offerings on commercially reasonable terms or at all. Also, our debt levels may impair our ability to obtain additional financing in the future. The sale of additional equity securities or convertible debt securities would result in additional dilution to our stockholders. In particular, the Warrants that we issued to the lenders in connection with the Credit Facilities contain anti-dilution provisions, among other things, including price protection anti-dilution protection in the event that the Company sells stock at a price below $1.00 per share in the case of the Penny Warrants and $1.25 per share in the case of the Premium Warrants. We cannot assure that additional financing, if required or desired, will be available in amounts or on terms acceptable to us, if at all.

If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges, and our business and ability to continue as a going concern may be adversely affected. If we need to accept less favorable terms, it could increase our cost of capital, reduce our cash balances or otherwise restrict our ability to grow.

We may not be able to fully utilize certain tax loss carryforwards.

As of June 30, 2025, we had approximately $260.9 million and $119.9 million in federal and state net operating loss carryforwards, respectively. The federal and state carryforwards expire in varying amounts beginning in 2029 for federal and 2026 for state purposes. In addition, as of June 30, 2025, we had federal and state research and development tax credit carryforwards of approximately $28.5 million and $22.8 million, respectively. The California research credits have no expiration date, but if not utilized, the federal research credits and other non-California state research credits will begin to expire in 2026.

Federal net operating losses arising in tax years beginning after December 31, 2017 are subject to an 80% of taxable income limitation (as calculated before taking the net operating losses into account). It is uncertain if and to what extent various states will conform to these limitations. In addition, utilization of our net operating loss and credit carryforwards is subject to annual limitation due to the application of the ownership change limitations provided by Section 382 of the Internal Revenue Code (“IRC”) and similar state provisions to us. Future changes in our stock ownership, including future offerings, as well as changes that may be outside of our control, could result in an ownership change under Section 382 of the IRC. In addition, the use of our net operating losses and other tax attributes may be subject to other limitations under applicable law. Additionally, one of the provisions under the Tax Cuts and Jobs Act that became effective in tax years beginning after December 31, 2021 required the capitalization and amortization of domestic and foreign research and experimental expenditures. On July 4, 2025, the One Big Beautiful Bill Act (the “OBBB Act”) was enacted, which makes a number of changes to U.S. federal income tax law, including permanently suspending the requirement to capitalize and amortize domestic research and development expenditures and permitting such deductions on a current basis. We are currently evaluating the full impact of the OBBB Act on us.

We are subject to the tax laws of various foreign jurisdictions, as well as within the United States, which are subject to unanticipated changes and interpretation and could harm our future results.

The application of tax laws of various foreign jurisdictions and within the United States is subject to interpretation and depends on our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of jurisdictions in which we operate may challenge our methodologies for valuing intercompany arrangements including our transfer pricing or determine that the manner in which we operate our business does not achieve the intended tax consequences. The application of tax laws can also be subject to conflicting interpretations by tax authorities in the various jurisdictions we operate. It is not uncommon for taxing authorities in different countries to have conflicting views, with respect to, among other things, the manner in which the arm’s length standard is applied for transfer pricing purposes. Further, tax laws are subject to change, which could adversely impact our tax rate. A number of countries, as well as organizations such as the Organization for Economic Cooperation and Development, support the 15% global minimum tax initiative ("Pillar Two"), and have adopted or intend to adopt laws to implement this initiative. However, on June 28, 2025, the G7 released a joint statement that it had reached an understanding with the United States for a side-by-side system based on certain accepted principles, including that U.S.-parented groups, such as ours, would be exempt from certain provisions of Pillar Two. Many countries and organizations are also actively considering changes to existing tax laws or have proposed or enacted new laws, such as the OBBB Act, that could increase our tax obligations in countries where we do business or cause us to change the way we operate our business, which could materially impact our results of operation.

Risks Related to the Regulation of our Products and Business

Modifications, upgrades, new indications and future products related to the CyberKnife or TomoTherapy Systems or the Precision Treatment Planning and iDMS Data Management System software may require new FDA 510(k) clearances or premarket approvals and similar licensing or approvals in international markets. Such modifications, or any defects in design, manufacture or labeling may require us to recall or cease marketing the affected systems or software until approvals or clearances are obtained.

The CyberKnife and TomoTherapy platforms as well as the Precision Treatment Planning software are medical devices that are subject to extensive regulation in the United States by local, state and the federal government, including the FDA. The iDMS Data Management System may be regulated as a medical device in some markets. The FDA most recently cleared Surface Guided Radiation Therapy (SGRT) on Radixact System under K223159 on June 23, 2023. ClearRTTM for onboard kVCT imaging was previously cleared on the Radixact System under K202412 on December 18, 2020. The FDA regulates virtually all aspects of a medical device design, development, testing manufacturing, labeling, storage, record keeping, adverse event reporting, sale, promotion, distribution and shipping. Before a new medical device, or a new intended use or indication or claim for an existing product, can be marketed in the United States, it must first receive either premarket approval or 510(k) clearance from the FDA, unless an exemption exists. Either process can be expensive, lengthy and unpredictable. The FDA’s 510(k) clearance process generally takes from three to twelve months, but it can last longer. The process of obtaining premarket approval is much more costly and uncertain than the 510(k) clearance process and it generally takes from one to three years, or even longer, from the time the application is filed with the FDA. Additionally, outside of the United States, our products are subject to clearances and approvals by foreign governmental agencies similar to the FDA. In order to market our products internationally, we must obtain licenses or approvals from these governmental agencies, which could include local requirements, safety standards, testing or certifications, and can be time consuming, burdensome and uncertain. Despite the time, effort and cost, there can be no assurance that a particular device or a modification of a device will be approved or cleared by the FDA or any foreign governmental agency in a timely fashion, if at all. Even if we are granted regulatory clearances or approvals, they may include significant limitations on the indicated uses of the product, which may limit the market for those products, and how those products can be promoted.

Medical devices may only be marketed for the indications for which they are approved or cleared. The FDA and other foreign governments also may change their policies, adopt additional regulations, or revise existing regulations, each of which could prevent or delay approval or clearance of our device, or could impact our ability to market our currently approved or cleared device. We are also subject to medical device reporting regulations, which require us to report to the FDA and other international governmental agencies if our products cause or contribute to a death or a serious injury, or malfunction in a way that would likely cause or contribute to a death or a serious injury. We also are subject to the QSR in the U.S. and ISO 13485 certification in many international markets, compliance with which is necessary to receive FDA and other international clearances or approvals to market new products and is necessary for us to be able to continue to market a cleared or approved product in the United States or globally. After a product is placed in the market, we are also subject to regulations by the FDA and Federal Trade Commission related to the advertising and promotion of our products to ensure our claims are consistent with our regulatory clearances, that there is scientific data to substantiate our claims and that our advertising is not false or misleading. Our products are also subject to state regulations and various worldwide laws and regulations.

A component of our strategy is to continue to upgrade the CyberKnife and TomoTherapy platforms as well as the Precision Treatment Planning with iDMS Data Management System software. Upgrades previously released by us required 510(k) clearance and international registration before we were able to offer them for sale. We expect our future upgrades will similarly require 510(k) clearance or approval; however, future upgrades may be subject to substantially more time-consuming data generation requirements and uncertain premarket approval or clearance processes. If we were required to use the premarket approval process for future products or product modifications, it could delay or prevent release of the proposed products or modifications, which could harm our business.

The FDA requires device manufacturers to make their own determination of whether or not a modification requires an approval or clearance; however, the FDA can review a manufacturer’s decision not to submit for additional approvals or clearances. Any modification to an FDA approved or cleared device that would significantly affect its safety or efficacy or that would constitute a major change in its intended use would require a new premarket approval or 510(k) clearance. We cannot assure you that the FDA will agree with our decisions not to seek approvals or clearances for particular device

modifications or that we will be successful in obtaining premarket approvals or 510(k) clearances for modifications in a timely fashion, if at all.

We have obtained 510(k) clearance for the CyberKnife platform for the treatment of conditions anywhere in the body when radiation treatment is indicated, and we have obtained 510(k) clearance for the TomoTherapy platform to be used as integrated systems for the planning and delivery of IMRT for the treatment of cancer. We have made modifications to the CyberKnife and TomoTherapy platforms in the past and may make additional modifications in the future that we believe do not or will not require additional approvals or clearances. If the FDA disagrees, based on new finalized guidance and requires us to obtain additional premarket approvals or 510(k) clearances for any modifications to the CyberKnife or TomoTherapy platforms and we fail to obtain such approvals or clearances or fail to secure approvals or clearances in a timely manner, we may be required to cease manufacturing and marketing the modified device or to recall such modified device until we obtain FDA approval or clearance and we may be subject to significant regulatory fines or penalties.

The FDA and similar governmental authorities in other countries in which we market and sell our products have the authority to require the recall of our products in the event of material deficiencies or defects in design, manufacture or labeling. A government mandated recall, or a voluntary recall by us, could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling and user manuals. Any recall could divert management’s attention, cause us to incur significant expenses, generate negative publicity, harm our reputation with customers, negatively affect our future sales and business, require redesign of the CyberKnife or TomoTherapy platform, and harm our operating results. In these circumstances, we may also be subject to significant enforcement action. If any of these events were to occur, our ability to introduce new or enhanced products in a timely manner would be adversely affected, which in turn would harm our future growth.

We are subject to federal, state and foreign laws and regulations applicable to our operations, the violation of which could result in substantial penalties and harm our business.

In addition to regulation by the FDA and similar governmental authorities in other countries, our operations are subject to other laws and regulations, such as laws and rules governing interactions with healthcare providers, anti-corruption laws, privacy rules and transparency laws. In order to maintain compliance with these laws and requirements, we must continually keep abreast of any changes or developments to be able to integrate compliance protocols into the development and regulatory documentation of our products. Failure to maintain compliance could result in substantial penalties to us and harm our business.

Laws and ethical rules governing interactions with healthcare providers. The Medicare and Medicaid “anti‑kickback” laws, and similar state laws, prohibit soliciting, offering, paying or accepting any payments or other remuneration that is intended to induce any individual or entity to either refer patients to or purchase, lease or order, or arrange for or recommend the purchase, lease or order of, healthcare products or services for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid. Such laws impact our sales, marketing and other promotional activities by reducing the types of financial arrangements we may have with our customers, potential customers, marketing consultants and other service providers. They particularly impact how we structure our sales offerings, including discount practices, customer support, product loans, education and training programs, physician consulting, research grants and other service arrangements. Many of these laws are broadly drafted and are open to a variety of interpretations, making it difficult to determine with any certainty whether certain arrangements violate such laws, even if statutory safe harbors are available. Generally, courts have taken a broad interpretation of the scope of the “anti-kickback” laws, holding that these laws may be violated if merely one purpose of a payment arrangement is to induce referrals or purchases. Further, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Violations of these laws can be punishable with prison time, and can also result in criminal fines, administrative civil money penalties and exclusion from participation in federal healthcare programs. In addition, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act.

Federal and state “false claims” laws generally prohibit the knowing filing or causing the filing of a false claim or the knowing use of false statements to obtain payment from government payors. Although we do not submit claims directly to payors, manufacturers can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by providing inaccurate billing or coding information to customers, or through certain other activities, including promoting products for uses or indications that are not approved by the FDA. In addition to actions initiated by the

government itself, the federal False Claims Act authorizes actions to be brought on behalf of the federal government by a private party having knowledge of the alleged fraud called a “relator.” Because the complaint is initially filed under seal, the action may be pending for some time before the defendant is even aware of the action. If the government is ultimately successful in obtaining redress in the matter or if the relator succeeds in obtaining redress without the government’s involvement, then the relator is typically entitled to receive a percentage of the recovery. When an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim, and may be excluded from participation in federal health care programs, and, although the federal False Claims Act is a civil statute, violations may also implicate various federal criminal statutes. Several states have also adopted comparable state false claims act, some of which apply to all payors.

We are also subject to federal and state physician self‑referral laws. The federal Ethics in Patient Referrals Act of 1989, commonly known as the Stark Law, prohibits, subject to certain exceptions, physician referrals of Medicare and Medicaid patients to an entity providing certain “designated health services” if the physician or an immediate family member has any financial relationship with the entity. The Stark Law also prohibits the entity receiving the referral from billing any good or service furnished pursuant to an unlawful referral. Various states have corollary laws to the Stark Law, including laws that require physicians to disclose any financial interest they may have with a healthcare provider to their patients when referring patients to that provider. Both the scope and exceptions for such laws vary from state to state.

If our past or present operations are found to be in violation of any of these “anti‑kickback,” “false claims,” “self‑referral” or other similar laws in foreign jurisdictions, we may be subject to the applicable penalty associated with the violation, which may include significant civil and criminal penalties, damages, fines, imprisonment and exclusion from healthcare programs. The impact of any such violations may lead to curtailment or restructuring of our operations, which could adversely affect our ability to operate our business and our financial results.

Anti‑corruption laws. We are also subject to laws regarding the conduct of business overseas, such as the FCPA, the U.K. Bribery Act of 2010, the Brazil Clean Companies Act, and other similar laws in foreign countries in which we operate. The FCPA prohibits the provision of illegal or improper inducements to foreign government officials in connection with the obtaining of business overseas. Becoming familiar with and implementing the infrastructure necessary to ensure that we and our distributors comply with such laws, rules and regulations and mitigate and protect against corruption risks could be quite costly, and there can be no assurance that any policies and procedures we do implement will protect us against liability under the FCPA or related laws for actions taken by our employees, executive officers, distributors, agents and other intermediaries with respect to our business. Violations of the FCPA or other similar laws by us or any of our employees, executive officers, distributors, agents or other intermediaries could subject us or the individuals involved to criminal or civil liability, cause a loss of reputation in the market, and materially harm our business.

Laws protecting patient health information. There are a number of federal and state laws protecting the confidentiality of certain patient health information, including patient records, and restricting the use and disclosure of that protected information. In particular, the U.S. Department of Health and Human Services (“HHS”) has promulgated patient privacy rules under the HIPAA. These privacy rules protect medical records and other personal health information of patients by limiting their use and disclosure, giving patients the right to access, amend and seek accounting of their own health information and limiting most uses and disclosures of health information to the minimum amount reasonably necessary to accomplish the intended purpose. The HIPAA privacy standard was amended by the Health Information Technology for Economic and Clinical Health Act, enacted as part of the American Recovery and Reinvestment Act of 2009. Although we are not a “covered entity” under HIPAA, we are considered a “business associate” of certain covered entities and, as such, we are directly subject to HIPAA, including its enforcement scheme and inspection requirements, and are required to implement policies, procedures as well as reasonable and appropriate physical, technical and administrative security measures to protect individually identifiable health information we receive from covered entities. Our failure to protect health information received from customers in compliance with HIPAA or other laws could subject us to civil and criminal liability to the government and civil liability to the covered entity, could result in adverse publicity, and could harm our business and impair our ability to attract new customers.

Transparency laws. The Sunshine Act, which was enacted by Congress as part of the Patient Protection and Affordable Care Act on December 14, 2011, requires each applicable manufacturer, which includes medical device companies such as Accuray, to track and report to the federal government on an annual basis all payments and other transfers of value from such applicable manufacturer to U.S. licensed physicians and teaching hospitals as well as physician ownership of such applicable manufacturer’s equity, in each case subject to certain statutory exceptions. Furthermore, on October 25, 2018, President

Trump signed into law the “Substance Use-Disorder Prevention that Promoted Opioid Recovery and Treatment for Patients and Communities Act” which in part (under a provision entitled “Fighting the Opioid Epidemic with Sunshine”) extends the reporting and transparency requirements for physicians in the Physician Payments Sunshine Act to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, and certified nurse midwives. Such data is available by the government on a publicly searchable website. Failure to comply with the data collection and reporting obligations imposed by the Sunshine Act can result in civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum of $150,000 per reporting period) and from $10,000 to $100,000 for each knowing failure to report (up to a maximum of $1 million per reporting period). In addition, we are subject to similar state and foreign laws related to the tracking and reporting of payments and other transfers of value to healthcare professionals, the violation of which could, among other things, result in civil monetary penalties and adversely impact our reputation and business.

Conflict minerals. The Dodd Frank Wall Street Reform and Consumer Protection Act and the rules promulgated by the SEC under such act require companies, including Accuray, to disclose the existence in their products of certain metals, known as “conflict minerals,” which are metals mined from the Democratic Republic of the Congo and adjoining countries. These rules require investigative efforts, which has caused and will continue to cause us to incur associated costs, could adversely affect the sourcing, availability and pricing of minerals used in our products and may cause reputational harm if we determine that certain of our components contain such conflict minerals or if we are unable to alter our processes or sources of supply to avoid using such materials, all of which could adversely impact sales of our products and results of operations.

If we or our distributors do not obtain and maintain the necessary regulatory approvals in a specific country, we will not be able to market and sell our products in that country.

To be able to market and sell our products in a specific country, we or our distributors must comply with applicable laws and regulations of that country. In jurisdictions where we rely on our distributors to manage the regulatory process, we are dependent on their ability to do so effectively. While the laws and regulations of some countries do not impose barriers to marketing and selling our products or only require notification, others require that we or our distributors obtain the approval of a specified regulatory body. These laws and regulations, including the requirements for approvals, and the time required for regulatory review vary from country to country. The governmental agencies regulating medical devices in some countries, for example, require that the user interface on medical device software be in the local language. We currently provide user guides and manuals, both paper copies and electronically, in the local language but only provide an English language version of the user interface. Obtaining regulatory approvals is expensive and time‑consuming, and we cannot be certain that we or our distributors will receive regulatory approvals in each country in which we market or plan to market our products. If we modify our products, we or our distributors may need to apply for additional regulatory approvals before we are permitted to sell them. We may not continue to meet the quality and safety standards required to maintain the authorizations that we or our distributors have received. It can also be costly for us and our distributors to keep up with regulatory changes issued or mandated from time to time. If we change distributors, it may be time‑consuming and disruptive to our business to transfer the required regulatory approvals, particularly if such approvals are maintained by our third‑party distributors on our behalf. If we or our distributors are unable to maintain our authorizations, or fail to obtain appropriate authorizations in a particular country, we will no longer be able to sell our products in that country, and our ability to generate revenue will be materially adversely affected.

Within the EU, we are required under the Medical Device Directive to affix the Conformité Européene (“CE”) mark on our products in order to sell the products in member countries of the EU. This conformity to the applicable directives is done through self‑declaration and is verified by an independent certification body, called a Notified Body, before the CE mark can be placed on the device. Once the CE mark is affixed to the device, the Notified Body will regularly audit us to ensure that we remain in compliance with the applicable European laws or directives. CE marking demonstrates that our products comply with the laws and regulations required by the European Union countries to allow free movement of trade within those countries. If we cannot support our performance claims and/or demonstrate or maintain compliance with the applicable European laws and directives, we lose our CE mark, which would prevent us from selling our products within the European Union. In addition, the EU’s Medical Device Regulation (“MDR”), which replaced the existing Medical Device Directive, became effective in May 2021. The MDR establishes new requirements and oversight for maintaining the CE mark. The official guidance continues to be published for the implementation of these requirements and the number of Notified Bodies are still limited. There may be variability in review timeframes and requirements as both manufacturers and authorities navigate these new requirements. In addition, the EU and Switzerland failed to establish a Mutual Recognition Agreement (“MRA”) for medical devices to include Switzerland within the MDR and as a result, Switzerland has initiated its own

medical device regulation similar to the EU MDR, which will require additional registrations for economic operators and products within Switzerland for our devices.

Under the Pharmaceutical Affairs Law in Japan, a pre‑market approval necessary to sell, market and import a product, or Shonin, must be obtained from the Ministry of Health, Labor and Welfare (“MHLW”), for our products. Before issuing approvals, MHLW examines the application in detail with regard to the quality, efficacy, and safety of the proposed medical device. The Shonin is granted once MHLW is content with the safety and effectiveness of the medical device. The time required for approval varies. A delay in approval could prevent us from selling our products in Japan, which could impact our ability to generate revenue and harm our business.

In addition to laws and regulations regarding medical devices, we are subject to a variety of environmental laws and regulations around the world regulating our operations, including those relating to the use, generation, handling, storage, transportation, treatment and disposal of hazardous materials, which laws impose compliance costs on our business and can also result in liability to us. Although we follow procedures intended to comply with existing environmental laws and regulations, risk of accidental contamination or injury can never be fully eliminated. In the event of an accident, state or federal or other applicable authorities may curtail our use of these materials and interrupt our business operations. In addition, future changes in these laws and regulations could also increase our costs of doing business. We must continually keep abreast of these standards and requirements and integrate our compliance into the development and regulatory documentation for our products. Failure to meet these standards could limit our ability to market our products in those regions that require compliance to such standards. For example, the European Union has adopted directives that may lead to restrictions on the use of certain hazardous substances or other regulated substances in some of our products sold there, unless such products are eligible for an exemption. While we believe that certain of our products are exempt, there can be no guarantee that such determination would not be challenged or that the regulations would not change in a way that would subject our products to such regulation. These directives, along with other laws and regulations that may be adopted by other countries, could increase our operating costs in order to maintain access to certain markets, which could adversely affect our business.

Healthcare reform legislation could adversely affect demand for our products, our revenue and our financial condition.

In March 2010, the Patient Protection and Affordable Care Act, as amended by Health Care and Education Reconciliation Act (collectively, the “ACA”) were signed into law. Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA. In particular, on December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. On June 18, 2021, the United States Supreme Court upheld the ACA, holding that the individuals who brought the lawsuit did not have standing to challenge the law. It is unclear how this decision and the decisions of the current administration will impact the ACA and our business. Complying with any new legislation or reversing changes implemented under the ACA could be time-intensive and expensive, resulting in a material adverse effect on our business.

The ACA includes a large number of health related provisions, including expanding Medicaid eligibility, requiring most individuals to have health insurance, establishing new regulations on health plans, establishing health insurance exchanges, requiring manufacturers to report payments or other transfers of value made to physicians and teaching hospitals, modifying certain payment systems to encourage more cost‑effective care and a reduction of inefficiencies and waste and including new tools to address fraud and abuse. The laws also include a decrease in the annual rate of inflation for Medicare payments to hospitals and the establishment of an independent payment advisory board to suggest methods of reducing the rate of growth in Medicare spending. We do not yet know the full impact that the ACA will have on our business. The expansion in the government's role in the U.S. healthcare industry may result in decreased profits to us, lower reimbursement by third-party payors for our products, or reduced volume of medical procedures conducted with our products, all of which could have a material adverse effect on our business, financial condition and results of operations. We cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

Future legislative or policy initiatives directed at reducing costs or limiting coverage or amounts of reimbursement available for our products could be introduced at either the federal or state level, which could have a negative impact on the demand for our products and services, and therefore on our financial position and results of operations. We cannot predict what healthcare reform legislation or regulations, if any, including any potential repeal or amendment of the ACA, will be

enacted in the United States or elsewhere, what impact any legislation or regulations related to the healthcare system that may be enacted or adopted in the future might have on our business, or the effect of ongoing uncertainty or public perception about these matters will have on the purchasing decisions of our customers. However, the implementation of new legislation and regulation may materially lower reimbursements for our products, materially reduce medical procedure volumes and significantly and adversely affect our business.

Risks Related to Our Common Stock

The price of our common stock is volatile and may continue to fluctuate significantly, which could lead to losses for stockholders.

The stock market in general has recently experienced relatively large price and volume fluctuations, particularly in response to macroeconomic factors. In addition, the trading prices of the stock of healthcare companies of our size can experience extreme price and volume fluctuations. These fluctuations often have been unrelated or out of proportion to the operating performance of these companies. Our stock price has experienced periods of volatility, including in recent quarters. Broad market fluctuations may also harm our stock price. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Any negative change in the public’s perception of the prospects of companies that employ similar technology or sell into similar markets could also depress our stock price, regardless of our actual results.

In addition to the other risk factors described above and below, factors affecting the trading price of our common stock include:

Future issuances of shares of our common stock could dilute the ownership interests of our stockholders.

Any issuance of equity securities could dilute the interests of our stockholders and could substantially decrease the trading price of our common stock. We may issue equity securities in the future for a number of reasons, including to finance our operations and business strategy (including in connection with acquisitions, strategic collaborations or other transactions), to adjust our ratio of debt to equity, to satisfy our obligations upon the exercise of outstanding options or for other reasons.

In addition, to the extent we issue common stock upon conversion of any outstanding convertible notes such as the 2026 Notes, that conversion would dilute the ownership interests of our stockholders.

The exercise of outstanding warrants for our common stock would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

The exercise of outstanding warrants to acquire our common stock will increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders. As of June 30, 2025, there are (i) an aggregate of 17,180,710 shares of our common stock issuable upon exercise of the Premium Warrants, and (ii) an aggregate of 6,247,531 shares of our common stock issuable upon exercise of the Penny Warrants (together, the “Warrants”). If we use the Delayed Draw Down Facility, we will be subject to issuing additional detachable warrants to our lender and its investors. Sales of substantial numbers of such shares in the public market could adversely affect the market price of our shares. In addition, the perceived risk of dilution as a result of the number of outstanding Warrants may cause our stockholders to be more inclined to sell their shares, which would contribute to a downward movement in the price of our common stock. Moreover, the perceived risk of dilution and the resulting downward pressure on our common stock price could encourage investors to engage in short sales of our common stock, which could further contribute to price declines in our common stock. The fact that our warrant holders can sell substantial amounts of our common stock in the public market could make it more difficult for us to raise additional funds through the sale of equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate, or at all.

In addition, the Warrants have certain anti-dilution protection provisions, including price protection anti-dilution protection in the event that the Company sells stock at a price below $1.00 per share in the case of the Penny Warrants and $1.25 per share in the case of the Premium Warrants. Depending on the nature and price of any equity issuances by us, the number of shares of common stock issuable upon the exercise of such Warrants could be increased and that would likely make an equity financing more difficult.

The conditional conversion features of the 2026 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional conversion features of the 2026 Notes are triggered, holders of the 2026 Notes, as applicable, will be entitled to convert such notes at any time during specified periods at their option. If one or more holders elect to convert such notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying solely cash in lieu of any fractional share), including if we have irrevocably elected full physical settlement upon conversion, we would be required to make cash payments to satisfy all or a portion of our conversion obligation based on the applicable conversion rate, which could adversely affect our liquidity.

Provisions in the indenture for the 2026 Notes, the Financing Agreement for our Credit Facilities, our certificate of incorporation and our bylaws could discourage or prevent a takeover, even if an acquisition would be beneficial in the opinion of our stockholders.

Provisions of our certificate of incorporation and bylaws could make it more difficult for a third‑party to acquire us, even if doing so would be beneficial in the opinion of our stockholders. These provisions include:

In addition, Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a change of control of our company. Generally, Section 203 prohibits stockholders who, alone or together with their affiliates and associates,

own more than 15% of the subject company from engaging in certain business combinations for a period of three years following the date that the stockholder became an interested stockholder of such subject company without approval of the board or 662/3% of the independent stockholders. The existence of these provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for shares of our common stock.

A change of control will also trigger an event of default under the Credit Facilities. If an event of default occurs, the agent for the lenders under the Credit Facilities may, at its discretion, suspend or terminate any of the lenders’ loan obligations thereunder and/or declare all or any portion of the loan then‑outstanding under the Credit Facilities, including all accrued but unpaid interest thereon, to be accelerated and immediately due and payable.

Furthermore, if a “fundamental change” (as such term is defined in the applicable indenture of the 2026 Notes) occurs, holders of the 2026 Notes will have the right, at their option, to require us to repurchase all or a portion of their convertible notes. A “fundamental change” generally occurs when there is a change in control of Accuray (acquisition of 50% or more of our voting stock, liquidation or sale of Accuray not for stock in another publicly traded company) or trading of our stock is terminated. In the event of a “make‑whole fundamental change” (as such term is defined in the applicable indenture of the 2026 Notes), we may also be required to increase the conversion rate applicable to the 2026 Notes surrendered for conversion in connection with such make‑whole fundamental change. A “make‑whole fundamental change” is generally a sale of Accuray not for stock in another publicly traded company. In addition, the applicable indentures for the Notes prohibits us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the 2026 Notes.

General Risks

Our liquidity could be adversely impacted by adverse conditions in the financial markets.

At June 30, 2025, we had $57.4 million in cash and cash equivalents. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of cash in our operating accounts and cash invested in money market funds. To date, we have experienced no material realized losses on or lack of access to our invested cash, or cash equivalents; however, we can provide no assurances that access to our invested cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

Actual events involving reduced or limited liquidity, defaults, non-performance or other adverse developments that affect domestic and international financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds may in the future lead to market-wide liquidity problems. In addition, the tightening of the credit markets would it make more difficult to raise capital through either debt or equity offerings on commercially reasonable terms or at all.

At any point in time, we also have funds in our operating accounts that are with third-party financial institutions that exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or become subject to other adverse conditions in the financial markets. To date, we have experienced no loss or lack of access to cash in our operating accounts.

Our operations are vulnerable to interruption or loss because of climate change, natural disasters, global or regional health pandemics or epidemics, terrorist acts and other events beyond our control, which has impacted and could in the future adversely affect our business.

Unexpected events beyond our control, including as a result of responses to epidemics or pandemics; fires or explosions; natural disasters, such as hurricanes, floods, tornadoes and earthquakes; war or terrorist activities (including the conflicts in Russia-Ukraine and the Middle East including with respect to Iran); unplanned outages; supply disruptions; and failures of equipment or systems, including telecommunications systems, or the failure to take adequate steps to mitigate the likelihood or potential impact of such events, could significantly disrupt our operations, delay or prevent product manufacturing and shipment for the time required to repair, rebuild or replace our manufacturing facilities, which could be lengthy, result in large expenses to repair or replace the facilities, and adversely affect our business, financial condition and results of operation.

Moreover, global climate change could result in certain types of natural disasters occurring more frequently or with more intense effects. The impacts of climate change may include physical risks (such as frequency and severity of extreme weather conditions), social and human effects (such as population dislocations or harm to health and well-being), compliance costs, transition risks, shifts in market trends, and other adverse effects. Such impacts may disrupt parties in our supply chain, our customers, and our operations. We have facilities in countries around the world, including two manufacturing facilities in Madison, Wisconsin and Chengdu, China, each of which is equipped to manufacture unique components of our products. We do not maintain backup manufacturing facilities for any of our manufacturing facilities or for our IT facilities, so we depend on each of our current facilities for the continued operation of our business. In addition, we conduct a significant portion of other activities, including administration and data processing, at facilities located in California, which has experienced major earthquakes and fires in the past, as well as other natural disasters. Chengdu, China, where one of our manufacturing facilities is located, has also experienced major earthquakes in the past. We do not carry earthquake insurance. Further, concerns about terrorism, the effects of a terrorist attack, political turmoil or an epidemic outbreak could have a negative effect on our operations and the operations of our suppliers and customers and the ability to travel, which could harm our business, financial condition and results of operations.

In addition, risks associated with climate change are subject to increasing societal, regulatory and political focus in the U.S. and globally. While the effects of climate change in the near-and long-term are difficult to predict, shifts in weather patterns caused by climate change are expected to increase the frequency, severity, or duration of certain adverse weather conditions and natural disasters, such as hurricanes, tornadoes, earthquakes, wildfires, droughts, extreme temperatures, or flooding, which could cause more significant business and supply chain interruptions, damage to our products and facilities as well as the infrastructure of hospitals, medical care facilities, and other customers, reduced workforce availability, increased costs of raw materials and components, increased liabilities, and decreased revenues than what we have experienced in the past from such events. In addition, increased public concern over climate change has and could result in new legal or regulatory requirements designed to mitigate the effects of climate change, including regulating greenhouse gas emissions, alternative energy policies, and sustainability initiatives. Although the SEC issued an order implementing a stay of its final climate-related disclosure rules, there have also been substantial legislative and regulatory developments on climate-related issues, including proposed, issued and implemented legislation and rulemakings that would require companies to assess and/or disclose climate metrics, risks, opportunities, policies and practices by both the Securities and Exchange Commission and California. These initiatives could result in the adoption of more stringent environmental laws and regulations or stricter enforcement of existing laws and regulations, which could result in increased compliance burden and costs to meet such regulatory obligations and could also impact how we source raw materials from suppliers, our manufacturing operations, and how we distribute our products. There has also been increasing scrutiny and changing expectations from the market and other stakeholders with respect to Environmental, Social, and Governance ("ESG") practices. Opinions, perspectives and expectations on ESG matters may differ among our stakeholders and may evolve over time. We have been and may continue to be subject to conflicting expectations and views on various matters, and legal requirements and interpretations may change. Any such developments could have a significant effect on our operating and financial decisions, including those involving capital expenditures to comply with new regulatory requirements or stakeholder expectations, which could harm our business, financial condition and results of operations. If we fail to comply with certain ESG-related laws, our products become non-compliant with such laws, or we fail to meet the expectations of our stakeholders on ESG-related matters, it could result in a loss of market access or a decline in our success in competitive bidding or public tender processes, and we could incur costs or face other sanctions, such as restrictions on our products entering certain jurisdictions, fines, and/or civil or criminal sanctions.

Changes in interpretation or application of generally accepted accounting principles may adversely affect our operating results.

We prepare our financial statements to conform to U.S. GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board, American Institute of Certified Public Accountants, the Public Company Accounting Oversight Board, the Securities and Exchange Commission and various other regulatory or accounting bodies. A change in interpretations of, or our application of, these principles can have a significant effect on our reported results and may even affect our reporting of transactions completed before a change is announced. Additionally, as we are required to adopt new accounting standards, our methods of accounting for certain items may change, which could cause our results of operations to fluctuate from period to period. Under the previous accounting guidance, we recognized system revenue upon acceptance when and if we have installation responsibilities. If circumstances change over time or interpretation of the revenue recognition rules change, we could be required to adjust the timing of recognizing revenue and our financial results could suffer.

We have not paid dividends in the past and do not expect to pay dividends in the foreseeable future.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all future earnings for the operation and expansion of our business and, therefore, do not anticipate declaring or paying cash dividends in the foreseeable future. The payment of dividends will be at the discretion of our board of directors and will depend on our results of operations, capital requirements, financial condition, prospects, contractual arrangements, and other factors our board of directors may deem relevant. If we do not pay dividends, a return on a stockholders’ investment will only occur if our stock price appreciates.

Item 2. PROPERTIES

Facilities

Our corporate headquarters are in Madison, Wisconsin. We lease approximately 460,000 square feet world-wide. We lease approximately 289,000 square feet in Madison, Wisconsin for product development, manufacturing, administrative, training and warehouse space. We lease approximately 59,000 square feet in Sunnyvale and Santa Clara, California for product research and development and administrative functions. We lease approximately 20,000 square feet in Morges, Switzerland, for administrative functions, and lease approximately 5,400 square feet in Genolier, Switzerland for training. We lease approximately 42,000 square feet of space in a manufacturing facility in Chengdu, China. We also lease offices in Solon, Ohio for research and development functions; and lease international offices in China; Hong Kong; Japan; Korea; India; and Spain.

We believe our current facilities are adequate to meet our current needs, but additional space, including additional radiation shielded areas in which systems can be assembled and tested, may be required in the future to accommodate anticipated increases in manufacturing needs.

Stock Information

Our common stock is traded on the Nasdaq Global Select Market under the symbol “ARAY.”

As of August 22, 2025, there were 164 stockholders of record of our common stock. Because many of our shares of common stock are held by brokers or other institutions on behalf of stockholders, we are unable to estimate the total number of beneficial stockholders and believe the number of stockholders of record underestimates our total number of stockholders.

We have never paid cash dividends on our common stock. Our Board of Directors intends to use any future earnings to support operations and reinvest in the growth and development of our business. There are no current plans to pay cash dividends to common stockholders in the foreseeable future.

Overview

Company

We are a radiation therapy company that develops, manufactures, sells and supports market-changing solutions that are designed to deliver radiation treatments for even the most complex cases, while making commonly treatable cases even more straightforward, to meet the full spectrum of patient needs. We believe in comparison to conventional linear accelerators, our treatment delivery, planning, and data management solutions provide better accuracy, flexibility, and control; fewer treatments with shorter treatment times; and the technology to expand beyond cancer, making it easier for clinical teams around the world to provide treatments that help patients get back to living their lives, faster.

Our innovative technologies, the CyberKnife and TomoTherapy® platforms, including the Radixact System, our next generation TomoTherapy platform, are designed to deliver advanced treatments, including stereotactic radiosurgery (“SRS”), stereotactic body radiation therapy (“SBRT”), intensity modulated radiation therapy (“IMRT”), image-guided radiation therapy (“IGRT”), and adaptive radiation therapy (“ART”). The CyberKnife and TomoTherapy platforms have complementary clinical applications with the same goal: to empower our customers to deliver the most precise and accurate treatments while still minimizing dose to healthy tissue, helping to reduce the risk of side effects that may impact patients’ quality of life. Each of these systems serves patient populations treated by the same medical specialty, radiation oncology, with advanced capabilities. The CyberKnife platform is also used by neurosurgeons specializing in radiosurgery to treat patients with tumors in the brain and spine, and neurologic and/or endocrine disorders. In addition to these products, we also

provide services which include post-contract customer support (warranty period services and post-warranty services), installation services, training, and other professional services.

Current Economic Conditions

We are subject to risks and uncertainties caused, directly or indirectly, by events with significant geopolitical and macroeconomic impacts, including, but not limited to, inflation; actions taken to counter inflation, including high interest rates; foreign currency exchange rate fluctuations; uncertainty and volatility in the banking and financial services sector; tightening credit markets; geopolitical concerns, such as the Russian-Ukraine and the Middle East conflicts and increasing tension between China and the U.S., including with respect to Taiwan; uncertainty caused by the China anti-corruption campaign and timing of the China stimulus program; changes in government administration policy positions; recent executive orders to impose new tariffs on global imports and uncertainties regarding impact, retaliations and further escalation, including against other countries; as well as other factors that may emerge. In particular, we are continuing to navigate supply chain and inflation challenges both of which continues to have a negative impact on our results of operations.

We expect that our customers’ business and our business will continue to be adversely impacted, directly or indirectly, by these macroeconomic and geopolitical issues. Inflation and the ongoing supply chain challenges and logistics costs have materially affected our gross margins and net income (loss), and we expect that gross margins and net income (loss) will continue to be adversely affected by increased material costs and freight and logistics expenses through at least calendar year 2025, and potentially longer. In addition, the Company expects inflation and the ongoing supply chain challenges and logistics costs to impact its cash from operations through at least calendar year 2025. In addition, reduced budgets and lower capital deployment priority for radiotherapy equipment, along with longer customer installation timelines, in the United States have negatively impacted our net revenue since fiscal year 2024, and we expect this will continue to have an impact through fiscal year 2026. The extent of the ongoing impact of these macroeconomic events on our business, our markets and on global economic activity however, is uncertain and the related financial impact cannot be reasonably estimated with any certainty at this time.

As a global company, approximately 70% of our raw materials and product components are sourced within the U.S. and finished products are assembled and manufactured within the U.S. with over 80% exported throughout the world. There remains significant tariff uncertainty, including related to existing tariffs associated with U.S.-China trade, which we expect will continue to have incremental costs to the company. If existing tariffs increase, we would expect minimal shipments to China despite customer demand. We are working to implement mitigations to the tariff policy impacts, however, we cannot predict the full impact or timing of such efforts and expect that sales to China will be adversely impacted, and our financial results will be adversely impacted through at least the first half of fiscal year 2026.

Our past results may not be indicative of our future performance, and historical trends including conversion of backlog to revenue, income (loss) from operations, net income (loss), net income (loss) per share and cash flows may differ materially. Accordingly, management is carefully evaluating our liquidity position, communicating with and monitoring the actions of our customers and suppliers, and reviewing our near-term financial performance as the uncertainty related to these factors continues to unfold. We also continue to evaluate our operating expenses. Our Board of Directors and our Compensation Committee determined that no payouts pursuant to the company bonus plan would be paid for fiscal year 2025 given that we would not have been compliant with the debt covenants in effect at the beginning of fiscal year 2025 and to reduce operating expenses and conserve cash in light of the uncertain macroeconomic environment due to tariffs. We also continue to evaluate our real estate needs and continue to assess our operations and how and to what extent we will continue to utilize our current real estate assets. The risks related to our business, including further discussion of the impact and possible future impacts of current economic conditions on our business, are further described in the section titled “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K.

Sale of Our Products

Generating revenue from the sale of our platforms is a lengthy process. Selling our platforms, from first contact with a potential customer to a signed sales contract that meets our backlog criteria (as discussed below) varies significantly and generally spans between six months and 30 months. The length of time between receipt of a signed contract and revenue recognition is generally governed by the time required by the customer to build, renovate or prepare the treatment room for installation of the platform. We report our customer revenues in five geographic regions: the Americas, EIMEA, Japan, China and Asia Pacific. The Americas region includes the United States, Canada and Latin America. The EIMEA region

includes Europe, India, the Middle East and Africa. The Asia Pacific region consists of Asia (excluding Japan and China), Australia and New Zealand.

In the United States, we primarily market directly to customers, including hospitals and stand-alone treatment facilities, through our sales organization we also market to customers through sales agents and group purchasing organizations. Outside the United States, we market to customers directly and through use of distributors and sales agents. In addition to our offices in the United States, we have international offices in Morges, Switzerland; Hong Kong, China; Shanghai, China and Tokyo, Japan and direct sales staff in most countries in Western Europe, Japan, India and Canada. In addition, we have distributors in Europe, Russia, the Middle East, Africa, the Asia Pacific region, and Latin America.

Joint Venture

In January 2019, our wholly-owned subsidiary, Accuray Asia Limited (“Accuray Asia”), entered into an agreement with CNNC High Energy Equipment (Tianjin) Co., Ltd. (the “CIRC Subsidiary”), a wholly-owned subsidiary of China Isotope & Radiation Corporation, to form a joint venture, CNNC Accuray (Tianjin) Medical Technology Co. Ltd. (the “JV”), to manufacture and sell radiation oncology systems in China. The JV aims to be uniquely positioned to serve China, which we believe is the world’s largest growth market for radiation oncology systems. China represents a significantly underserved market for linacs based on the country’s population and cancer incidence rates on both an absolute and relative country basis. Accuray Asia has a 49% ownership interest in the JV and the CIRC Subsidiary has a 51% ownership interest in the JV.

The JV sells our products in China, much like a distributor and also manufactures and sells a locally branded “Made in China” radiotherapy device, the Tomo C radiation therapy system, in the Class B license category. We believe this strategy will allow us to best maximize both near and longer-term opportunities in China. In September 2023, we received approval for our Class B device from the National Medical Products Administration (“NMPA”) and our Accuray Precision Treatment Planning System for the Class B device was approved by the NMPA in June 2024. The JV also distributes other Accuray treatment delivery systems like the Radixact and CyberKnife treatment delivery systems, including the Radixact SynC and CyberKnife S7 Systems, which received NMPA approval in January 2025. The JV also distributes other Accuray treatment delivery systems like the Radixact and CyberKnife treatment delivery systems.

There remains significant tariff uncertainty, including related to existing tariffs associated with U.S.-China trade, which we expect will continue to have incremental costs to the company. We are working to implement mitigations to the tariff policy impacts, however, we cannot predict the full impact or timing of such efforts and expect that sales to China will be adversely impacted, and our financial results will be adversely impacted through at least the first half of fiscal year 2026.

Backlog

In order for the product portion of a system sales agreement to be included in backlog, it must meet the following criteria:

Our backlog includes contractual agreements with our customers for the purchase of our CyberKnife or TomoTherapy platforms, including the Radixact Systems and related upgrades. The amount of backlog recognized into revenue is primarily

impacted by three items: cancellations, age-outs and age-ins, and foreign currency fluctuations. We cannot provide assurance that we will convert backlog into recognized revenue, primarily due to factors outside of our control, such as:

A summary of gross orders, net orders, and order backlog is as follows (in thousands):

Gross Orders and Book-to-Bill Ratio

Gross orders are defined as the sum of new orders recorded during the period, adjusted for any revisions to existing orders during the period.

Gross orders decreased by $54.1 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, mostly due to a decrease in gross orders from the Americas region.

Our book-to-bill ratio is defined as gross orders for the period divided by product revenue for the period. Our book-to-bill ratio for the year ended June 30, 2025, was 1.2 as compared to 1.5 for the year ended June 30, 2024. A book-to-bill ratio greater than 1.2 indicates strong demand for our products. This metric allows management to monitor our business development efforts to ensure we grow our backlog and our business over time.

In recent years, the percentage of gross orders received from our distribution partners in the international markets represented 81% and 74% of gross orders for fiscal year ended June 30, 2025 and 2024, respectively. We anticipate that distributor orders from international markets will continue to represent a significant portion of our gross orders in the foreseeable future. International orders are affected by foreign currency fluctuation as well as government programs that stimulate the purchase of healthcare products, both of which could affect the demand for our products and timing of orders from period to period. In addition, our order-to-revenue conversion cycle for international distributor orders has been generally longer, compared to that of direct channel sales and could cause fluctuations in our age-outs from period to period.

Net Orders

Net orders are defined as gross orders, less cancellations, age-outs net of age-ins, foreign exchange and other adjustments during the period. Net orders decreased by $33.7 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to the decrease in gross orders, partially offset by $6.8 million in lower cancellations and $8.0 million in favorable foreign exchange currency impacts.

Results of Operations

Fiscal 2025 results compared to fiscal 2024

Net revenue

Net revenue by sales classification is as follows:

Products net revenue increased by $3.4 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, mostly driven by a $5.9 million increase in revenue from upgrades, partially offset by lower revenue from unit sales due to product mix.

Services net revenue increased by $8.5 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to a $4.0 million increase in revenue from service contracts as a result of growth in our installed base and a $3.8 million increase in revenue from the purchase of spare parts from customers.

Net revenue by geographic region, which is based on the shipping location of our customer, is as follows:

Net revenue increased $12.0 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024. Products net revenue increased primarily due to a higher volume of the shipment of systems in our China and APAC regions, partially offset by a decrease in the volume of the shipment of systems in our EIMEA region. Services net revenue increased primarily in our EIMEA, China and Japan regions, partially offset by a decrease in services net revenue in our Americas region. The decrease in net revenue from EIMEA was due to lower product sales in fiscal year 2025, which was impacted by geopolitical disruptions in the region.

Gross profit

Gross profit is as follows:

Gross profit increased by $4.0 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, due to an increase in net revenue, partially offset by a $3.6 million increase in the net deferred gross profit on sales to the JV.

Operating Expenses

Research and development expenses decreased by $1.8 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to $2.5 million in lower compensation and benefits resulting from a reduction in headcount in fiscal year 2025 driven by our restructuring program in fiscal year 2024, and $1.7 million for the capitalization of internal labor for software development to be sold, partially offset by $1.1 million in higher spending for research and development projects and an a $1.0 million increase in facility and information system costs.

Selling and marketing expenses increased by $0.7 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to investments in our sales operations infrastructure and an increase in travel costs, partially offset by a $1.6 million decrease in commissions due to lower sales in the Americas and EIMEA regions in fiscal year 2025.

General and administrative expenses decreased by $2.2 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to a $2.1 million decrease in consulting costs driven by the completion of the implementation of our ERP system in fiscal year 2024 and a $1.9 million reduction in rental expense due to cost savings measures, partially offset by a $1.9 million increase in compensation and benefits that was driven by merit increases and stock-based compensation.

Income from equity method investment

Income from the equity method investment increased by $2.9 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily as a result of an increase in revenues from the JV.

Interest expense

Interest expense increased $1.3 million during the year ended June 30, 2025, as compared to the year ended June 30, 2024, primarily due to interest paid-in-kind accrued on the new Term Loan Facility and additional debt financing costs related to the new Term Loan Facility.

Gain on extinguishment of debt

We recorded a $1.5 million gain on the extinguishment of a portion of our Convertible Notes and our prior term loan facility. The gain on extinguishment is comprised of a $2.4 million gain on the settlement of shares issued to the holders of the Convertible Notes offset by $0.9 million from the write-off of unamortized debt issuance costs.

Loss from change in fair value of warrant liability

We recorded a $0.5 million loss due to the change in the fair value of the Penny Warrants from the issuance date through June 30, 2025.
