Accuray Inc. (ARAY) is a leading global provider of advanced radiation oncology solutions for the treatment of cancer. The company has a rich history of technology innovation that has enabled it to carve out a unique position in the highly competitive radiotherapy market. With a strong pipeline of new products and growing international presence, Accuray is well-positioned to capitalize on rising demand for advanced cancer treatment solutions.

Business Overview

Accuray was founded in 1990 and is headquartered in Madison, Wisconsin. The company designs, develops, and sells advanced radiosurgery and radiation therapy systems for the treatment of tumors throughout the body. Accuray's primary products are the CyberKnife and TomoTherapy platforms, which are used for stereotactic radiosurgery, intensity modulated radiation therapy, image-guided radiation therapy, and adaptive radiation therapy.

In its early years, Accuray faced significant challenges in gaining market acceptance for its innovative CyberKnife technology. As a new entrant in the radiation therapy market, the company had to invest heavily in marketing and customer education efforts to demonstrate the benefits of stereotactic radiosurgery compared to traditional radiation therapy methods.

Despite these initial hurdles, Accuray was able to establish the CyberKnife as a leading platform for the treatment of tumors and neurological disorders. In 2003, the company made a strategic move to expand its product portfolio by acquiring TomoTherapy Incorporated, adding image-guided intensity modulated radiation therapy capabilities to its offerings.

The integration of TomoTherapy presented operational challenges for Accuray in the years following the acquisition. The company had to manage the complexities of combining two very different product platforms, sales forces, and manufacturing facilities. However, the TomoTherapy technology ultimately proved to be a successful addition to Accuray's portfolio, providing an important complement to the CyberKnife system.

Throughout its history, Accuray has navigated a highly competitive radiation therapy market, facing strong incumbents such as Varian Medical Systems and Elekta. To maintain its technological edge, the company has continuously invested in research and development. Regulatory approvals for new indications and product upgrades have also been an ongoing operational and financial consideration for Accuray.

Product Segments

Accuray's business is primarily driven by two key product segments: CyberKnife and TomoTherapy.

The CyberKnife platform is a robotic radiosurgery system used for the treatment of tumors anywhere in the body, including the brain, spine, lung, prostate, liver, and pancreas. The system uses image-guidance technology and a compact linear accelerator mounted on a robotic arm to deliver precise, high-dose radiation treatments. Key features of the CyberKnife system include the ability to track and correct for tumor and patient movement in real-time, deliver treatments with sub-millimeter accuracy, and complete treatments in just 1-5 sessions rather than the typical 30-40 sessions required with traditional radiation therapy. The CyberKnife platform is used by neurosurgeons and radiation oncologists to treat patients with tumors or other medical conditions.

The TomoTherapy platform, including the Radixact System, is an advanced radiation therapy system that uses CT imaging and intensity-modulated radiation therapy (IMRT) to deliver precise radiation treatments. The TomoTherapy systems are capable of treating a wide variety of cancer types throughout the body and are used for treatments such as IMRT, image-guided radiation therapy (IGRT), and adaptive radiation therapy (ART). Key features of the TomoTherapy platform include the ability to integrate CT imaging for improved targeting, deliver treatments with sub-millimeter accuracy, and allow for real-time treatment plan adaptation based on changes in tumor size, shape, and position.

Financial Analysis

Accuray's financial performance has been mixed in recent years, though the company has demonstrated signs of momentum in key areas. For the fiscal year ended June 30, 2024, the company reported total revenue of $446.6 million, up 2.2% year-over-year. Product revenue, which accounts for around 55% of the total, grew 6.8% to $246.0 million, driven by strong demand for the company's CyberKnife and TomoTherapy systems. However, service revenue declined 1.9% to $200.6 million, reflecting pandemic-related headwinds that have impacted installations and service activations.

On the bottom line, Accuray generated a net loss of $15.5 million in fiscal 2024, compared to a $9.3 million loss the prior year. The company's adjusted EBITDA, a key profitability metric, was $5.7 million, down from $8.4 million in fiscal 2023. Margin pressure stemmed from inflationary cost increases, supply chain disruptions, and investments in R&D and sales/marketing to support the company's growth initiatives.

For the six months ended December 31, 2024, Accuray reported total net revenue of $217.7 million, up 3% year-over-year. Product revenue was $109.6 million, up 4% year-over-year, while service revenue was $108.2 million, up 2% year-over-year. Gross profit for the six-month period was $76.4 million, representing a gross margin of 35.1%. The company's operating expenses were $73.8 million, down 4% compared to the prior year period. Accuray reported a net income of $1.4 million for the six months ended December 31, 2024.

Liquidity and Balance Sheet

Looking at the balance sheet, Accuray ended fiscal 2024 with $68.6 million in cash and cash equivalents, down from $89.4 million a year earlier. As of December 31, 2024, the company had $62.6 million in cash and cash equivalents. Total debt stood at $210.8 million, up from $199.5 million in the prior year, as the company has utilized its credit facilities to fund operations and strategic investments. The company's net debt position of $103.6 million represents a debt-to-EBITDA ratio of 18.2x, indicating a highly leveraged capital structure.

Accuray has a $40 million revolving credit facility and an $80 million term loan facility, with $17 million and $60 million outstanding, respectively, as of December 31, 2024. The company also has $100 million in 3.75% convertible senior notes due 2026 outstanding. The debt-to-equity ratio stands at 4.46, while the current ratio is 1.62 and the quick ratio is 0.88.

From a liquidity perspective, Accuray generated negative free cash flow of $15.5 million in fiscal 2024, compared to positive $2.9 million the prior year. The company's working capital position remains healthy, with $127.9 million in net working capital as of June 30, 2024. The company's order backlog, which represents the value of booked orders that have not yet been recognized as revenue, was $463.1 million at the end of the quarter ended December 31, 2024.

Quarterly Performance and Outlook

In the fiscal second quarter of 2025, which ended December 31, 2024, Accuray reported solid financial results that exceeded market expectations. Total revenue increased 8.0% year-over-year to $116.2 million, driven by 19% growth in product revenue to $61.2 million. This strong product performance was led by robust demand for the company's CyberKnife systems, as well as accelerating sales of the newly-introduced Tomo C system in China through the CIRC joint venture.

Service revenue was relatively flat at $55.0 million, though the company noted that this figure was impacted by the timing of revenue recognition related to its ERP system implementation in the prior year period. Adjusted EBITDA for the quarter was $9.6 million, a significant improvement from $2.0 million in the year-ago quarter, reflecting the impact of pricing actions and operational efficiency initiatives.

Looking at performance by geographic markets, Accuray reports revenue in five regions: the Americas, EIMEA, Japan, China, and Asia Pacific. Revenue from the China region grew over 50% year-over-year, while revenue from Japan grew over 40% compared to the prior year. Revenue from the EIMEA and Americas regions declined compared to the prior year.

Looking ahead, Accuray has raised its full-year fiscal 2025 guidance. The company now expects total revenue in the range of $463 million to $475 million, up from the prior range of $462 million to $472 million. Adjusted EBITDA guidance has also been increased to $28.5 million to $31 million, compared to the previous $28 million to $30 million range.

This guidance reflects Accuray's confidence in continued momentum in its product business, particularly in China, as well as the company's ability to navigate ongoing macroeconomic headwinds impacting the global healthcare industry. The company noted that it expects a more pronounced seasonality in its business this fiscal year, with a larger portion of revenue and earnings coming in the fourth quarter. The guidance assumes minimal impact from tariffs and a gradual recovery in the U.S. market in the second half of fiscal 2025.

Risks and Conclusion

While Accuray has demonstrated its ability to innovate and expand its global footprint, the company faces several risks that could impact its long-term growth trajectory. These include intense competition in the radiotherapy market from major competitors such as Varian Medical Systems, Elekta, RefleXion Medical, and Zap Surgical Systems. The company's success depends on its ability to develop and market innovative products that offer advantages over competing technologies.

Other risks include regulatory hurdles for new product approvals, reimbursement uncertainties that could impact customer purchasing decisions, and ongoing supply chain and inflationary pressures. The company's financial performance can be impacted by factors such as delays in customer installations, changes in government or health insurance reimbursement policies, and competition from new market entrants or existing competitors.

Additionally, Accuray's highly leveraged balance sheet leaves it vulnerable to rising interest rates and potential covenant breaches on its credit facilities. The company's reliance on a small number of large customers, particularly in China, also introduces concentration risk.

Overall, Accuray's strong innovation track record, growing international presence, and improving operational efficiency suggest the company is well-positioned to capitalize on the attractive long-term fundamentals of the radiation oncology market. The company's focus on technological innovation, expanding the capabilities of its radiation therapy platforms, and maintaining a strong order backlog position Accuray well to meet the evolving needs of the cancer treatment market. However, investors should closely monitor the company's ability to navigate near-term macroeconomic headwinds and execute on its strategic growth initiatives in order to drive sustainable profitability and shareholder value creation.
