Updates Financial Guidance

SUNNYVALE, Calif., April 30, 2014 — Accuray Incorporated (Nasdaq: ARAY) announced today financial results for the third fiscal quarter and nine months ended March 31, 2014.

Third Quarter Highlights

·                  Gross orders of $45.2 million

·                  Total revenue of $97.1 million increases 38% from the third fiscal quarter 2013

·                  Gross profit margin expands to 40.9%

·                  Achieves adjusted EBITDA of $7.8 million and positive cash flow from operations of $13.7 million

“The third quarter was marked by EBITDA profitability and positive cash flow from operations, driven by revenue growth and margin expansion.  Our upwardly revised revenue guidance range reflects continued momentum in the business,” said Joshua H. Levine, president and chief executive officer of Accuray.  “As expected, net order funnel management was challenging and resulted in fewer orders this quarter, but we are confident in the downstream impact of our commercial execution improvements, including the focus on developing a high leverage GPO contract portfolio as we have separately reported today with the announcement of our contract with Novation.”

“We remain focused on our strategic growth agenda and believe our improving operational and commercial execution, coupled with fiscal discipline, will continue to create value for our stakeholders,” continued Mr. Levine.  “We are confident that our efforts to ensure customers realize the value of our precise, innovative tumor treatments and the service and support we provide to them are the right strategies to drive long-term growth for Accuray.”

Use of Non-GAAP Financial Measures

The company has supplemented its GAAP net loss with a non-GAAP measure of adjusted earnings before interest, taxes, depreciation, amortization and stock-based compensation (“adjusted EBITDA”). 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 more meaningful comparison of results for current periods with previous operating results.  Additionally, it will assist management in analyzing future trends, making strategic and business decisions and establishing internal budgets and forecasts. A reconciliation of non-GAAP adjusted EBITDA to GAAP net loss (the most directly comparable GAAP measure) is provided in the schedule below.

There are limitations in using this non-GAAP financial measure because it is not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies.  This non-GAAP financial measure 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 and the reconciliations of the non-GAAP financial measure provided in the schedule below.
