Accuray (ARAY) Telefonkonferenz zu den Ergebnissen des 4. Quartals des Geschäftsjahres 2026: Servicewachstum, Rückgang der Produktumsätze

Wichtigste Erkenntnisse

• Der Umsatz im vierten Quartal des Geschäftsjahres 2026 sank im Jahresvergleich um 21 % auf 100,9 Millionen US-Dollar. Der Gesamtjahresumsatz ging um 12 % auf 402 Millionen US-Dollar zurück, was in erster Linie auf geringere Produktverkäufe zurückzuführen ist.
• Der vierteljährliche Serviceumsatz stieg um 6 % auf 60,1 Millionen US-Dollar, unterstützt durch Preisanpassungen, eine größere installierte Basis und höhere Abrechnungen außerhalb von Serviceverträgen. Die Service-Bruttomarge verbesserte sich von 34,4 % auf 36,8 %.
• Der Produktumsatz im vierten Quartal fiel um 42 % auf 40,8 Millionen US-Dollar. Im Geschäftsjahr 2026 ging der Produktumsatz um 27 % auf 173 Millionen US-Dollar zurück, wovon etwa 58 Millionen US-Dollar des Rückgangs auf China entfielen.
• Das bereinigte EBITDA im vierten Quartal stieg von 9,4 Millionen US-Dollar auf 12,9 Millionen US-Dollar, während das bereinigte EBITDA für das Gesamtjahr von 28,3 Millionen US-Dollar auf 10,6 Millionen US-Dollar fiel.
• Accuray erzielte im Geschäftsjahr 2026 Kosten- und Margeverbesserungen von mehr als 20 Millionen US-Dollar und übertraf damit sein Ziel von 12 Millionen US-Dollar. Das Management erwartet für das Geschäftsjahr 2027 eine zusätzliche jährliche Verbesserung von etwa 15 Millionen US-Dollar, abhängig von Nachfrage, Kosten und makroökonomischen Rahmenbedingungen.
• Das Unternehmen gab aufgrund von Unsicherheiten bezüglich der Produktnachfrage, Zöllen, China, dem Nahen Osten und allgemeinen geopolitischen Rahmenbedingungen keine formelle Prognose für den Umsatz oder das bereinigte EBITDA im Geschäftsjahr 2027 ab.

Wichtige Finanzdaten

Accuray beendete das Quartal mit einem ausgewiesenen Auftragsbestand von etwa 313 Millionen US-Dollar, der nur Aufträge enthält, die jünger als 30 Monate sind. Die liquiden Mittel, Zahlungsmitteläquivalente und Zahlungsmittel mit Verfügungsbeschränkung beliefen sich auf insgesamt 48,8 Millionen US-Dollar, während die Netto-Vorräte im Vergleich zum Vorquartal um 9,6 Millionen US-Dollar auf 147,1 Millionen US-Dollar sanken.

Geschäfts- und operative Entwicklung

Der Servicebereich blieb das primäre Wachstumsfeld von Accuray. Der Serviceumsatz im vierten Quartal profitierte mit rund 1,4 Millionen US-Dollar von Vertragspreisen und mit 1,8 Millionen US-Dollar vom Wachstum der installierten Basis sowie höheren Abrechnungen nach Zeit und Aufwand. Fast 90 % der aktiven Systeme waren weiterhin durch Serviceverträge abgedeckt.

Die Bruttomarge im Servicebereich stieg im vierten Quartal im Jahresvergleich um 2,4 Prozentpunkte auf 36,8 %. Preisanpassungen trugen 2,3 Punkte und geringere Personalkosten im Servicebereich 5,3 Punkte bei, was teilweise durch Zölle sowie Material- und Frachtinflation ausgeglichen wurde. Im Vergleich zum Vorquartal verbesserte sich die Servicemarge um 10,7 Punkte aufgrund von Preisanpassungen, geringerem Ersatzteilverbrauch und niedrigeren Frachtkosten.

Die Produktperformance blieb schwach. Im Geschäftsjahr 2026 sank der Produktumsatz um 65 Millionen US-Dollar, wovon rund 58 Millionen US-Dollar auf geringere Umsätze in China im Zuge geopolitischer Spannungen und Zollunsicherheiten zurückzuführen waren. Die ausgewiesene Bruttomarge für Produkte im vierten Quartal lag bei 31,7 %; ohne zollbedingte positive Effekte von 5,8 Millionen US-Dollar errechnete das Management jedoch eine bereinigte Produkt-Bruttomarge von 17,5 %.

Die kommerzielle Umstrukturierung trug zu einem Book-to-Bill-Verhältnis von 1,1 im Geschäftsjahr 2026 bei, was unter dem vom Management angestrebten gesunden Niveau von 1,2 liegt. Accuray gab bekannt, dass die Neuausrichtung der Vertriebsregionen und Führungswechsel weitgehend abgeschlossen sind, und das Management ist überzeugt, dass eine gestärkte Vertriebsorganisation, Produktverbesserungen und ein höheres Engagement der Vertriebspartner im Geschäftsjahr 2027 einen besseren Auftragseingang unterstützen können.

Accuray tritt in die zweite Phase seines Transformationsprogramms ein, die sich auf differenzierte Technologie, weitere Kostensenkungen, eine erweiterte Marktreichweite sowie höhere Serviceumsätze und -margen konzentriert. Zu den technologischen Prioritäten gehören das Synchrony-Bewegungsmanagement, die volumetrische Bildgebung ClearRT sowie softwaregestützte Planung, Workflows und adaptive Behandlungsmöglichkeiten.

Das Unternehmen hob zudem Partnerschaften hervor, die darauf abzielen, seine Fähigkeiten in den Bereichen Bildgebung, Software, Engineering, KI und Kundensupport auszubauen. Dazu gehören unverbindliche Absichtserklärungen mit Sansoft-HMEAmerica und Forschungslaboren, eine erweiterte Beziehung zu Tata Consultancy Services sowie eine 10-jährige Zusammenarbeit mit der University of Wisconsin School of Medicine and Public Health.

Good day, and welcome to the Accuray Fourth Quarter Fiscal 2026 Financial Results Conference Call. [Operator Instructions] Please note this event is being recorded.

I would now like to turn the conference over to Mr. Steve Monroe, Vice President of Corporate Financial Planning and Analysis. Please go ahead, sir.

Stephen Monroe

Thank you, operator, and good afternoon, everyone. Welcome to Accuray's conference call to review financial results for the fourth quarter of fiscal year 2026, which ended June 30, 2026. During our call this afternoon, management will review recent corporate developments. Joining us on today's call are Steve LaNeve, Accuray's President and Chief Executive Officer; and Ali Pervaiz, Accuray's Chief Financial Officer.

Before we begin, I would like to remind everyone that our discussion today includes forward-looking statements. Actual results may differ materially from those contemplated or implied by these forward-looking statements. Factors that could cause actual results to differ materially are outlined in today's earnings release and in our filings with the Securities and Exchange Commission. We undertake no obligation to update any forward-looking statements, except as required by law.

In addition, we will discuss certain non-GAAP financial measures. Reconciliations to the most directly comparable GAAP measures are provided in today's earnings release. There is also a supplemental slide presentation available on the Investor Relations section of our website.

With that, let me turn the call over to Steve LaNeve.

Stephen LaNeve

Thank you, Steve. Good afternoon, and thank you for joining us. Fiscal 2026 was an important year for Accuray. Last October, we began a comprehensive effort to evaluate every aspect of our business, engage with customers around the world, improve accountability and operating discipline and position Accuray for sustainable long-term success. Over the last several quarters, we have streamlined our organization, strengthened commercial leadership, sharpened our strategic focus and our execution, reduce our cost structure, work towards expanding partnerships and taken significant steps to improve our financial position. These actions were all designed with a common objective in mind, building a stronger, more competitive and more profitable Accuray.

While the operating environment remained challenging throughout much of fiscal 2026 due to geopolitical uncertainty, tariff pressures and regional market volatility. We remain focused on the factors within our control and have executed well against the transformation plan we introduced in December of last year. As a result of these actions, Accuray is fundamentally stronger than it was a year ago. We have strengthened our financial foundation, upgraded our people and processes, focused on core competencies by expanding our ecosystem of strategic partners, advanced key technology platforms and service solutions, improved organizational discipline, increased our installed base and are now entering the next phase of our transformation. which consists of decisive steps to strengthen our competitive position, enhance customer value and drive long-term growth in revenues and margins.

One of the most encouraging developments has been the positive response we are seeing from customers, partners and the broader radiation oncology community. The exceptional engagement we experienced at ESTRO 2026 is illustrative of this response. Our booth remained highly active throughout the event. Our clinical symposium with standing room only and the quality of customer discussions was robust. Together, these interactions reinforced our belief that the market increasingly recognizes the value of Accuray's innovation in precision treatment delivery, adaptive therapy, real-time motion management and intelligent software solutions.

Importantly, clinical data presented at ESTRO by global clinical leaders reinforced the growing role of precision, short-course radiotherapy across multiple disease sites. in prostate cancer, presentations from SunrofIL Scientific Institute Italy and the European Institute of Oncology supported the feasibility and early safety of highly precise motion-managed ultra-hypofractionated treatment approaches using the CyberKnife platform. This data is built on broader published evidence space that includes randomized Phase III prostate SBRT data and mature long-term robotic SBRT outcomes showing favorable relapse-free survival with very low severe toxicity.

In breast cancer, investigators shared encouraging clinical global experience with the treatment delivery on both robotic and helical platforms. The National Institute of Oncology, Hungary, reported institutional experience with partial breast irradiation while researchers from the European Institute of Oncology, Italy, provided an update further supporting the feasibility and safety of this approach. Preliminary outcomes from patients treated on the Radixact platform, incorporating the recent introduced vital hold system represented by CHR Mette and bill frees. highlighting the potential of integrated surface-guided radiotherapy and automated breath hold delivery to support precision treatment delivery.

Additional data across kidney, lung, functional radio surgery and other precision radiotherapy use cases further reinforced the breadth of Accuray's clinical relevance across multiple disease sites. These Estro presentations built upon a broader and expanding body of published clinical evidence supporting Accuray technologies. This includes randomized Phase III prostate SBRT data and mature long-term robotic SBRT outcomes demonstrating favorable disease control and low rates of severe toxicity, further strengthening the evidence base that supports our differentiated approach to radiation therapy.

Lastly, ESTRO 2026 was not simply about visibility. It was about momentum. The event translated strong interest into measurable commercial activity which led to a meaningful increase in qualified leads year-over-year. We also saw encouraging traction from the European debut of Stellar as well as continued interest in the unique capabilities of the CyberKnife System. This engagement reinforces our confidence that the investments we have made in innovation, partnerships and commercial execution are gaining traction in the market and creating opportunities for future growth.

This afternoon, I will discuss our progress across 5 areas: number one, financial foundation; number two, strategic partnerships and our ecosystem; number three, differentiated technology; number four, transformation Phase 2 and number five, the FY '27 outlook. Our financial foundation. Let me begin with what I believe is 1 of the most important developments in the company's recent history. Last month, we announced a comprehensive transaction with TCW Asset Management Company, LLC. that fundamentally strengthens our financial position and enhances our ability to execute our strategy. The transaction includes a conversion of $40 million of existing debt in the preferred equity that is convertible into common shares of more than 100% premium to where the common stock was trading immediately prior to the announcement.

A $15 million cash investment in additional convertible preferred equity, additional liquidity available through a delayed broad facility, a covenant holiday through December 2027 and several governance and capital structure enhancements. I will add that certain elements of the transaction, such as the issuance of convertible preferred equity remains subject to shareholder approval and other customary closing conditions, as fairly described in our related Form 8-K filing.

Collectively, these actions would improve liquidity, reduce leverage, enhance financial flexibility and provide a greater runway to execute our strategic priorities. We appreciate the continued support and confidence demonstrated by our partners at TCW. Importantly, these steps allow us to spend less time managing capital constraints and more time investing in our customers, innovation, commercial execution and profitable growth. This transaction was not simply a financing exercise. It was designed to create a stronger foundation for the next phase of Accuray evolution and beyond.

Strategic partnerships and our ecosystem. The second area I would like to discuss is partnerships in our expanding clinical ecosystem. One of the key conclusions that emerge from our transformation work is an actuation to one's resources to the areas where we create the greatest valve by focusing on core competencies and competitive differentiators while partnering with world-class organizations to further accelerate innovation and execution. We have taken important steps to build exactly that type of ecosystem.

Recently, we entered into nonbinding letters of intent with Sansoft-HMEAmerica and research laboratories while continuing to expand our relationship with Tata Consultancy Services. These relationships are intended to strengthen our capabilities across volumetric imaging, software development, adaptive therapy, engineering and customer support while simultaneously producing operational efficiencies that we could not capture on our own.

Additionally, we announced in May, a landmark 10-year strategic collaboration with the University of Wisconsin School of Medicine and Public Health. This relationship is especially meaningful because it builds upon decades of shared innovation. Many of the technologies that helped establish Accuray's helical platform originated from groundbreaking work conducted at the University of Wisconsin.

Today, we are extending that legacy by creating a framework designed to advance adaptive radiation therapy research, education, training, and the next generation of personalized cancer treatment using our stellar adaptive radiation therapy platform. Together, these relationships are allowing us to build an ecosystem that extends our capabilities while enabling Accuray to remain sharply focused on our core competencies. radiation therapy innovation, clinical excellence, treatment delivery, patient outcomes and customer solutions.

By partnering with world-class organizations across imaging, software, engineering, AI and services, we can accelerate innovation, improve execution and increase efficiency [Audio Gap] without having to build every capability internally ourselves. We believe this approach can accelerate innovation while also improving efficiency and scalability across the business over time. Importantly, this is not a onetime effort. We view strategic partnerships as a key pillar of our operating model going forward. We expect to continue expanding our ecosystem with additional partnerships that further enhance our capabilities and create value for customers and shareholders.

Differentiated technology. Innovation remains central to our strategy. As we look ahead, our product road map, including the CyberKnife and Radixact Systems, is increasingly centered around 3 areas of differentiated technology. First is motion management. Synchrony remains 1 of the most differentiated capabilities in radiation therapy and enables clinicians to track and adapt to patient and tumor motion in real time during treatment. Leveraging Accuray's proprietary software and AI-enabled algorithms, Synchrony helps predict, track and compensate for motion throughout treatment. positioning Accuray at the forefront of Intelligent Motion Management.

As precision medicine continues to evolve, we believe the importance of motion management will only increase. Second is imaging. ClearRT continues to provide high-quality volumetric imaging that supports treatment planning, patient positioning, adaptive workflows and clinical decision-making on our Radixact platform. As the field increasingly emphasizes precision and adaptation, Accuray's innovation road map will continue to prioritize enhanced imaging on the Ratings Act and CyberKnife Systems.

Third is software. In response to our voice of customer findings, we continue to invest in precision. VOLO, workflow enhancements and software-enabled treatment optimization capabilities. We believe software will play an increasingly important role in driving both clinical and operational value. Bolo's advanced optimization engine enables faster, high-quality treatment planning while ongoing investments in workflow automation and adaptive treatment capabilities help improve efficiency, support clinician productivity and further differentiate the Accuray treatment platform.

What gives us confidence is not only the technology itself, but also the growing body of supporting clinical evidence. At ESTRO 2026, data presented by key opinion leaders highlighted compelling outcomes across multiple indications, including impressive kidney treatment results and long-term prostate cancer outcomes demonstrating excellent disease control with low toxicity profiles. These clinical findings reinforce our belief that Accuray's differentiated technology platform remains well positioned as radiation oncology increasingly shifts towards adaptive, precise and personalized treatment approaches.

Our transformation Phase II. The first phase of our transformation program focused primarily on creating a more efficient and competitive operating model and a more agile, responsive and accountable enterprise. We streamlined our organization, simplified decision-making, improved accountability, reduce costs, strengthen commercial focus and improved operational discipline. With the incredible efforts of our team, we were able to exceed the financial benefits of our transformation actions.

As we had previously communicated, we were expecting approximately $12 million of cost and margin improvement in fiscal 2026, which represented roughly $25 million of annualized benefit. Through disciplined execution, we ultimately realized more than $20 million of cost and margin improvement during fiscal 2026 versus a target of $12 million. These realized improvements are expected to support approximately $15 million of incremental annualized cost and margin improvement in fiscal 2027. With the degree of contribution depending on product demand levels, the cost environment and broader business and macro conditions.

Now we are entering transformation Phase II. This next stage of Accuray's transformation focuses on the following priorities: differentiated innovation, investing in technologies and capabilities where Accuray possess unique competitive advantages, continuing to lower our cost structure, driving further efficiency, leveraging technology and partnerships and removing complexity throughout the organization. expanded market reach improving commercial execution, strengthening distributor performance, growing customer and channel partner engagement and expanding market penetration globally.

Service revenue and margin expansion, driving growth in service revenues and margins through price optimization more efficient parts and personnel utilization using remote diagnostics and introduction of value-added solutions our customers have been asking for. We believe these initiatives help position us to improve both revenue growth and profitability over time.

As we enter fiscal 2027, we are doing so from a position of greater strength than a year ago. Our priorities remain clear: executing on our transformation initiatives, improving profitability, expanding recurring revenue and creating long-term shareholder value. At the same time, geopolitical developments, trade policy uncertainty, tariff impacts, conditions in China and the Middle East and broader macroeconomic factors continue to create significant uncertainty around product demand and margins.

Given the long sales cycle inherent in our business, these factors can also affect the timing of orders, installations and revenue recognition. As a result, we are not providing formal revenue or adjusted EBITDA guidance for fiscal 2027. Instead, we expect continued growth in service revenue, improved service margins driven primarily by pricing optimization and operational efficiencies, ongoing operating expense discipline and continued benefits from our transformation initiatives. We also expect strategic partnerships to play an increasingly important role in expanding our capabilities while allowing us to remain focused on our core competencies.

While product revenue and margin performance remain difficult to predict, we believe the actions taken over the past year have strengthened the business and improved our ability to execute in fiscal 2027.

With that, I'll turn the call over to Ali.

Ali Pervaiz

Thank you, Steve, and good afternoon, everyone. I would like to begin by thanking our global teams for their focus, commitment and execution throughout this transformational year. Turning to the financial results for fiscal year 2026, fourth quarter and full fiscal year.

Net revenue for the quarter was $100.9 million, which was down 21% versus the prior year on both a reported and constant currency basis. For the full fiscal year, total revenue was $402 million, down 12% from last year and down 14% on a constant currency basis. The decreases for both periods were driven by lower product revenues partially offset by higher service revenue.

Service revenue for the fourth quarter was $60.1 million, up $3.2 million or 6% from the prior year and up 5% on a constant currency basis. Approximately $1.4 million of that increase was attributable to service contract pricing actions, while the remaining $1.8 million increase was driven by an increase in our global installed base and higher out-of-contract time and material billings.

Full year service revenue was $229 million, up $8.3 million or 4% from last year and up 2% on a constant currency basis. The increase was driven by approximately $5.4 million related to service contract pricing actions, while the remaining $2.9 million increase was driven by an increase in our global installed base and higher out-of-contract time and material billings.

The company's contract capture rate defined as a percentage of active systems covered by a service agreement continues to be at nearly 90% across our active installed base.

Product revenue for the fourth quarter was $40.8 million, down $29.9 million or 42% versus the prior year on both a reported and constant currency basis. For the full year, product revenue was $173 million, down $65 million or 27% as compared to the prior year and down 28% on a constant currency basis. Approximately $58 million of that decline was attributable to lower revenue in China versus prior year, resulting from a sustained geopolitical tension and ongoing tariff uncertainty.

Product gross orders for the fourth quarter were approximately $38 million and represented a book-to-bill ratio of 0.9x. For the full year, gross orders totaled $192 million representing a trailing 12-month book-to-bill ratio of 1.1. We ended the fourth quarter with a reported order backlog of approximately $313 million defined to include only orders younger than 30 months.

As we previously stated, we consider our book-to-bill ratio of 1.2 to be a healthy level for our growing backlog. While we fell short of that target in fiscal 2026 as we implemented significant commercial transformation initiatives, including sales region realignment and leadership changes, those foundational actions are now largely complete.

We have strengthened our commercial organization and developing a healthier pipeline, have introduced product improvements and are improving engagement with our distribution partners. We believe these actions position us to improve order intake as we move through fiscal 2027.

Overall, gross profit for the quarter was $35.1 million, representing gross margin of 34.8% compared to gross margins of 30.6% in the prior year. In the fourth quarter, the company recorded favorability of $5.8 million or 5.7 points related to EPA tariff expenses incurred prior to those tariffs being invalidated by the Supreme Court earlier this year.

Additionally, a nonrecurring write-down of an obsolete component unfavorably impacted fiscal 2026 fourth quarter gross margins by 30.5%. For the full year, overall gross profit was $111 million, representing gross margins of 27.7% compared to gross margins of 32.1% in the prior fiscal year. Note that $5.5 million or 95% of the EPA tariff favorability was related to tariff expense that was recognized in fiscal year 2026.

Service gross profit for the quarter was $22.1 million, representing gross margins of 36.8% compared to gross margins of 34.4% in the prior year. Service contract pricing actions drove margins higher by $1.4 million or 2.3 points and lower overall service labor cost structure improved margins by $3.2 million or 5.3 points as compared to the prior year. Offsetting these items was primarily the impact of tariffs as well as inflationary pressures on materials and freight, which had an unfavorable impact of $2.4 million or 4 points.

On a sequential basis, service gross margins were 10.7 points higher than the third quarter of fiscal 2026 driven by favorable pricing, lower parts consumption and lower freight costs. The fourth quarter improvement reflects the benefits of pricing actions and operational initiatives implemented throughout fiscal 2026, which gained momentum during the second half of the year. For the full year, service gross profit was $71 million, representing gross margins of 31% compared to gross margins of 32.6% in the prior year. Service contract pricing actions drove margins higher by $5.4 million or 2.4 points and lower overall service labor cost structure improved margins by $8.3 million or 3.6 points as compared to prior year.

This favorability was primarily offset by higher net parts consumption of approximately $11.2 million or 4.9 points. Product gross profit in the quarter was $12.9 million, representing 31.7% of gross margins compared to 27.5% in the prior year. As noted above, the EPA tariff favorability of $5.8 million or 1.2 points were recorded in the fourth quarter drove product margins higher. Excluding this favorability, pro forma product gross profit was approximately $7.1 million, representing adjusted product gross margins of 17.5%.

The lower product gross margins were also impacted by the unfavorable obsolete inventory impact, higher non-EPA tariff expense and unfavorable product and region mix of product shipments. For the full year, product gross profit was $40.4 million, representing 23.4% of gross margins compared to 31.6% in the prior year. Excluding the $0.3 million EPA tariff favorability related to prior periods to fiscal year 2026, adjusted product gross profit was approximately $40.1 million representing adjusted product gross margins of 23.2%.

The year-over-year decrease was driven by non-iEPtariff expense and unfavorable product and region mix in particular, significantly fewer CyberKnife system shipments to China. Operating expenses in the fourth quarter were $29.6 million compared to $34.7 million in the prior fiscal year. The current year fourth quarter includes $0.7 million of nonrecurring restructuring expenses, which includes severance costs and other costs directly related to our restructuring and transformation plans.

Excluding these restructuring expenses, fourth quarter 2026 operating expenses decreased $5.9 million or 17% versus the prior year. For the full year, operating expenses were $137.9 million compared to $139.1 million in the prior year, excluding restructuring expenses of $16.2 million operating expenses decreased to $121.7 million, a decrease of 13% year-over-year.

As Steve mentioned earlier, our transformation initiatives continue to deliver measurable results in fiscal 2026 generating more than $20 million in bottom line improvements realized during the fiscal year compared to our previously communicated target of $12 million. These benefits are translating into a higher long-term savings opportunity and are expected to support approximately $15 million of incremental annualized cost and margin improvement in fiscal 2027 with the degree of contribution depending upon product demand levels, the cost environment and broader business and macro conditions.

As noted earlier, we recognized $16.2 million of nonrecurring restructuring expenses in fiscal year 2026. As our transformation plan has progressed over the second half of fiscal 2026, we expect restructuring costs related to our transformation plan to be substantially complete. Operating income for the quarter was $5.5 million compared to $4.2 million in the prior year. Operating income for the full year was a loss of $26.4 million compared to income of $7.8 million in the prior year.

Adjusted EBITDA for the quarter was $12.9 million compared to $9.4 million in the prior year. Adjusted EBITDA for the full year was $10.6 million compared to $28.3 million in the prior year. We described the reconciliation between GAAP net income and adjusted EBITDA in our earnings release issued today.

Turning to the balance sheet. Total cash, cash equivalents and restricted cash as of quarter end amounted to $48.8 million compared to $44.4 million at the end of last quarter. The restricted cash is related to required postings for cash flow hedging and tariffs amounting to $8.1 million in the current quarter as compared to $6.4 million at the end of last quarter. Net accounts receivable were $67.4 million, up $2.8 million from the prior quarter.

Our net inventory balance was $147.1 million, down $9.6 million from the prior quarter as finished goods inventory built early in the second half of fiscal 2026 was monetized in the fourth quarter. At the end of the fourth quarter, we had $5 million outstanding on our revolving credit facility. In May, the company drew the full $18 million under its prior preexisting delayed draw term loan facility and used the proceeds to pay off $18 million of outstanding convertible notes that matured on June 1.

We also recently announced a comprehensive transaction with TCW that will significantly strengthen our balance sheet and liquidity position. Under the agreement, TCW will exchange $40 million of existing term debt for convertible preferred equity with an equivalent liquidation preference. The preferred shares will accrue dividends at 8% annually and are convertible into common stock at a conversion price of $0.50 per share, representing an approximately 105% premium to our share price at announcement.

In addition, TCW has made a $15 million convertible preferred equity investment and has agreed to make available a delayed draw term loan of up to $5 million, providing additional liquidity and financial flexibility. The transaction also includes a covenant holiday with certain financial covenants waived through December 31, 2027, and the first covenant testing date set for March 31, 2028, giving us additional runway to execute our strategic priorities and planned investments.

As Steve mentioned earlier, portions of the TCW transaction remains subject to shareholder approval and other customary closing conditions. We look forward to engaging with shareholders as we move through that process. We're excited to continue our partnership with TCW and appreciate their confidence in our transformation plan and long-term opportunity. In addition, we plan to implement a reverse stock split at a ratio still to be determined and subject to stockholder approval, which we believe will better position the company moving forward.

Collectively, these actions would strengthen our capital structure, improve financial flexibility and support our focus on driving sustainable profitability and long-term shareholder value.

Stephen LaNeve

Thank you, Ali. Fiscal 2026 was a year of transformation. Fiscal 2027 is a year of execution. We are strengthening our financial foundation. We are expanding our partnership ecosystem. We sharpened our focus on differentiated technology, we improve the way we operate, and we established the framework for transformation Phase I.

Most importantly, we remain focused on helping customers deliver exceptional patient care while positioning Accuray to generate sustainable long-term value for shareholders.

I will now turn it back over to the operator For Q&A.
