Accuray Generates 10% Year-Over-Year Gross Order Growth in First Quarter

Commercial Momentum Continues; Management Reaffirms Fiscal 2016 Guidance

SUNNYVALE, Calif., October 29, 2015 — Accuray Incorporated (NASDAQ: ARAY) announced today financial results for the fiscal first quarter ended September 30, 2015.

Fiscal First Quarter Highlights

· Gross orders were $64.9 million, representing 10 percent year-over-year growth or 18 percent on a constant currency basis

· Total revenue was $89.6 million, an increase of 9 percent year-over-year or 12 percent on a constant currency basis

· Gross profit margin expanded to 38 percent from 34 percent in the prior year period, driven by both improved product and service margins

· Adjusted EBITDA was a positive $2.3 million compared to a negative $8.5 million in the prior year, representing a $10.8 million improvement

· Cash and investments increased $9.2 million compared to a $19.2 million decrease in the prior year quarter

· Single and dual vault sites comprised more than 50 percent of total TomoTherapy® System orders

“We executed on our commercial strategies during the first quarter, resulting in continued momentum in order activity and improvements in overall financial performance,” said Joshua H. Levine, president and chief executive officer of Accuray. “Our team focused on positioning the TomoTherapy System as a mainstream device, which led to more than 50 percent of its orders during the quarter being placed by sites with single or dual vaults. At the same time, we continued to see order momentum for the CyberKnife® M6™ with the InCise™ Multileaf Collimator as our first installation sites demonstrated its ability to provide extremely precise treatments in significantly reduced time for an expanded patient population.”

Financial Highlights

Gross product orders totaled $64.9 million for the 2016 fiscal first quarter, an increase of $6.1 million or 10 percent from the first quarter of the prior fiscal year. On a constant currency basis, gross product orders increased 18 percent from the prior fiscal year first quarter. Ending product backlog was $379.8 million, approximately 4 percent higher than backlog at the end of the prior fiscal year first quarter.

Total revenue was $89.6 million, an improvement of 9 percent from the prior fiscal year first quarter and an increase of 12 percent on a constant currency basis. The Americas region total revenue was $45.3 million and total revenue outside of the Americas region was $44.3 million. Product revenue increased 21 percent to $40.0 million while service revenue totaled $49.6 million, which was a slight increase compared to the prior year.

Total gross profit for the fiscal first quarter of 2016 was $33.9 million or 37.8 percent of sales, comprised of product gross margin of 42.5 percent and service gross margin of 34.1 percent. This compares to total gross margin of 33.7 percent, product gross margin of 37.4 percent and service gross margin of 31.3 percent for the prior fiscal year first quarter. On a constant currency basis, total gross margin for the first quarter of fiscal 2016 was 38.6 percent.

Operating expenses were $37.7 million, a decrease of 12 percent compared with $43.1 million in the prior fiscal first quarter. The decrease was primarily because of timing of tradeshow related expenses in sales and marketing, as well as reduced compensation related expenses in sales and marketing and general and administrative functions, offset by a slight increase in research and development to support ongoing product development efforts.

Net loss improved to $9.6 million, or $0.12 per share, for the first quarter of fiscal 2016, compared to a net loss of $21.7 million, or $0.28 per share, for the first quarter of fiscal 2015.

Adjusted EBITDA for the first quarter of fiscal 2016 was a positive $2.3 million, compared to an $8.5 million loss in the first quarter of the prior fiscal year.

Cash, cash equivalents, and investments were $153.1 million as of September 30, 2015, an increase of $9.2 million from June 30, 2015.

2016 Financial Guidance

Accuray reaffirmed its financial guidance for fiscal 2016 on total revenue of $395 million to $410 million and adjusted EBITDA of $25 million to $35 million.

This financial guidance is unchanged from that provided on August 20, 2015.

Use of Non-GAAP Financial Measures

Accuray 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. A reconciliation of GAAP net loss (the most directly comparable GAAP measure) to non-GAAP adjusted EBITDA is provided in the schedule below.

Accuray presents certain measures, such as period-over-period revenue growth, on a constant currency basis, which excludes the effects of foreign currency translation. Due to the continuing strengthening of the U.S. dollar against foreign currencies and the overall variability of foreign exchange rates from period to period, management uses these measures on a constant currency basis to evaluate period-over-period operating performance. Measures presented on a constant currency basis are calculated by translating current period results at prior period monthly average exchange rates.

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.
