アキュレイ（ARAY）2026年度第4四半期決算説明会：サービス事業の成長と製品売上高の減少

主な要点

• 2026年度第4四半期の売上高は前年同期比21%減の1億90万ドルとなりました。 通期売上高は主に製品販売の減少により、前年比12%減の4億200万ドルとなりました。
• 四半期のサービス売上高は、価格改定、設置台数の拡大、および契約外請求の増加に支えられ、前年同期比6%増の6,010万ドルとなりました。 サービス粗利益率は前年同期の34.4%から36.8%に改善しました。
• 第4四半期の製品売上高は42%減の4,080万ドルとなりました。2026年度通期の製品売上高は27%減の1億7,300万ドルとなり、減少額のうち約5,800万ドルは中国市場に起因するものでした。
• 第4四半期の調整後EBITDAは前年同期の940万ドルから1,290万ドルに増加した一方、通期の調整後EBITDAは前年の2,830万ドルから1,060万ドルに減少しました。
• アキュレイは2026年度に、1,200万ドルの目標を超える2,000万ドル以上のコストおよび粗利益改善を達成しました。 経営陣は、需要、コスト、マクロ経済状況に左右されるものの、2027年度には年換算で約1,500万ドルの追加改善を見込んでいます。
• 同社は、製品需要、関税、中国、中東、およびより広範な地政学的状況を巡る不確実性を理由に、2027年度の売上高および調整後EBITDAの公式業績予想（ガイダンス）を提示しませんでした。

主要財務データ

アキュレイの当四半期末における報告ベースの受注残高は約3億1,300万ドルとなり、これには受注から30ヶ月未満の注文のみが含まれています。 現金・現金同等物および拘束性預金の合計は4,880万ドルとなり、純在庫は前四半期比で960万ドル減少して1億4,710万ドルとなりました。

事業および業績

サービス事業は引き続きアキュレイの主要な成長分野でした。第4四半期のサービス売上高は、契約価格の改定により約140万ドル、設置台数の拡大および実費請求（タイム・アンド・マテリアル）の増加により180万ドルのプラス効果を得ました。稼働中のシステムの90%近くが引き続きサービス契約でカバーされています。

第4四半期のサービス粗利益率は、前年同期比で2.4ポイント上昇し36.8%となりました。価格改定が2.3ポイント、サービス人件費の削減が5.3ポイントの寄与となりましたが、関税や部材・運賃のインフレにより一部相殺されました。前四半期比では、価格改定、部品消費量の減少、および運賃コストの低減により、サービス利益率は10.7ポイント改善しました。

製品業績は引き続き低迷しました。2026年度の製品売上高は6,500万ドル減少しましたが、これには地政学的緊張や関税を巡る不確実性を背景とした中国での売上減少分約5,800万ドルが含まれます。第4四半期の報告ベース製品粗利益率は31.7%でしたが、関税関連のプラス効果580万ドルを除外した場合、経営陣が試算した調整後製品粗利益率は17.5%となりました。

商業部門の再編が寄与し、2026年度のBBレシオ（ブック・ツー・ビル・レシオ）は1.1となりましたが、経営陣が健全とする水準である1.2を下回りました。アキュレイは、販売地域の再編とリーダーシップの交代が概ね完了したとしており、経営陣は営業組織の強化、製品の改善、および代理店との連携強化により、2027年度中の受注獲得状況が改善すると見込んでいます。

アキュレイは事業変革プログラムの第2段階に入りつつあり、差別化された技術、更なるコスト削減、市場アクセスの拡大、そしてサービス売上高と利益率の向上に注力しています。技術的な優先事項には、Synchrony動体追従技術、ClearRT3次元画像撮影、およびソフトウェア主導の計画、ワークフロー、適応放射線治療機能が含まれます。

同社はまた、画像診断、ソフトウェア、エンジニアリング、AI、カスタマーサポート機能の拡張を目指したパートナーシップを強調しました。これには、Sansoft-HMEAmericaおよび研究機関との法的拘束力のない基本合意書（LOI）、タタ・コンサルタンシー・サービシズとの提携強化、ならびにウィスコンシン大学医学公衆衛生学研究科との10年間にわたる共同研究が含まれます。

資本構造

アキュレイは、流動性の強化と負債削減を目的としたTCWアセット・マネジメント（TCW Asset Management Company, LLC）との取引を発表しました。株主承認および一般的な完了条件を満たすことを前提として、TCWは4,000万ドルのタームローン債務を転換優先株と交換し、さらに1,500万ドルを転換優先株に投資します。

優先株の年配当率は8%で、普通株1株当たり0.50ドルで転換可能です。これは発表時の株価を約105%上回る水準です。TCWはまた、最大500万ドルのディレイドドロー・タームローン（分割実行型借入）の提供にも合意しました。一部の財務制限条項（コベナント）は2027年12月31日まで免除され、2028年3月31日からテストが再開される予定です。

アキュレイはまた、株主の承認を前提として、比率は未定であるものの株式併合を計画しています。

業績見通し

経営陣は2027年度の公式な売上高および調整後EBITDAの見通しを発表しませんでした。同社は、継続的なサービス売上高の成長、価格改定と業務効率化によるサービス利益率の改善、規律ある営業費用、および事業変革イニシアチブからのさらなる成果を見込んでいます。

アキュレイは、2027年度に年換算で約1,500万ドルの追加的なコストおよび利益率の改善を見込んでいます。経営陣は、実現する貢献度は製品需要、コスト環境、ならびに広範なビジネスおよびマクロ経済状況に依存すると警告しました。

リスクおよび注視点

• 特に中国および中東において、製品需要と利益率の予測が引き続き困難となっています。
• 地政学的動向、貿易政策、関税を巡る不確実性が、受注、コスト、地域別売上高に影響を与える可能性があります。
• 営業サイクルが長期にわたることで、受注、設置、および売上計上のタイミングがずれる可能性があります。
• 製品および地域の構成比、非EPA関税、部品コスト、運賃、インフレが利益率を圧迫する可能性があります。
• TCWとの取引の一部および提案された株式併合には、株主の承認およびその他の完了条件が必要です。

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.
