Other Recent Operational Highlights

“While I am disappointed in our quarterly results where we faced challenges as a result of multiple factors, including a delay in product shipments and slower than expected U.S. installations, we remain confident in our growth strategy and our ability to offer value to our customers globally,” said Suzanne Winter, Chief Executive Officer. “Fiscal 2024 is an important year for the company as we start to make major advances in long-term growth and profitability drivers, which we highlighted at our investor day this past fall. We remain focused on executing on our plan to advance care with innovative solutions, improving patient access by penetrating higher growth emerging markets and investing in our service business.

Fiscal Year 2024 Financial Guidance

Accuray’s financial guidance is based on current expectations. The following statements are forward-looking and actual results could differ materially depending on market and economic conditions, supply chain disruption, and the factors set forth under “Safe Harbor Statement” below.

The company is adjusting its guidance for fiscal year 2024 as follows:

Guidance for non-GAAP financial measures excludes depreciation and amortization, stock-based compensation, interest expense, provision for income taxes, and ERP and ERP related expenditures. For more information regarding the non-GAAP financial measures discussed in this press release, please see "Use of Non-GAAP Financial Measures" below.

An archived webcast will also be available on Accuray’s website until Accuray announces its results for the fourth quarter of fiscal 2024.

Use of Non-GAAP Financial Measures

Accuray reports its financial results in accordance with generally accepted accounting principles in the United States (“GAAP”) and the rules of the SEC. To supplement its financial statements prepared and presented in accordance with GAAP, Accuray uses certain non-GAAP financial measures, such as adjusted EBITDA, and net revenue on a constant currency basis.

Accuray has supplemented its GAAP net income (loss) with a non-GAAP measure of adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation, ERP and ERP related expenditures and restructuring charges (“adjusted EBITDA”). The calculation of adjusted EBITDA also excludes certain non-recurring, irregular and one-time items. Management believes that this non-GAAP financial measure provides useful supplemental information to management and investors regarding the performance of the company and facilitates a meaningful comparison of results for current periods with previous operating results. A reconciliation of GAAP net income (loss) (the most directly comparable GAAP measure) to non-GAAP adjusted EBITDA is provided in the schedules below.

Accuray has also reported certain operating results on a constant currency basis in order to facilitate period-to-period comparisons of its results without regard to the impact of foreign currency exchange rate fluctuations. Management believes disclosure of non-GAAP constant currency results is helpful to investors because it facilitates period-to-period comparisons of the company’s results by increasing the transparency of the underlying performance by excluding the impact of foreign currency exchange rate fluctuations. The GAAP measure most directly comparable to net revenue on a constant currency basis is revenue. Accuray calculates the constant currency amounts by translating local currency amounts in the current period using the same foreign translation rate used in the prior period being compared against rather than the actual exchange rate in effect during the current period.

There are limitations in using these non-GAAP financial measures because they are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for GAAP financial measures. Investors and potential investors should consider non-GAAP financial measures only in conjunction with the company’s consolidated financial statements prepared in accordance with GAAP.
