Accuray Reports Record Revenue in Fiscal Fourth Quarter and Fiscal Year Ended 2007

- Revenue Growth of 166 Percent Year Over Year -
- Total Backlog Reaches Record Level of $619 Million -

SUNNYVALE, Calif., August 16, 2007 — Accuray Incorporated (Nasdaq: ARAY), the global leader in radiosurgery throughout the body, today announced financial results for the fiscal fourth quarter and full fiscal year ended June 30, 2007.

For the fiscal fourth quarter of 2007, Accuray reported total revenue of $44.0 million, compared to fiscal fourth quarter 2006 total revenue of $21.4 million. Revenue for the fiscal year ending June 30, 2007 was $140.5 million, a 166 percent increase over total revenue of $52.9 million for fiscal year 2006.

On a generally accepted accounting principles (GAAP) basis, net income for fiscal fourth quarter 2007 was $0.5 million or $0.01 per basic and diluted share, compared to a net loss of $7.9 million, or a loss of $0.49 per basic and diluted share during the same period in 2006. Net loss for the fiscal year ended June 30, 2007 was $5.6 million, or a loss of $0.18 per basic and diluted share, compared to a net loss of $33.7 million, or a loss of $2.11 per basic and diluted share for fiscal year 2006.

On a non-GAAP basis, which excludes non-cash stock-based compensation charges, net income for the fourth quarter of fiscal 2007 was $3.3 million, or $0.05 per diluted share. Non-GAAP net income for the fiscal year ended June 30, 2007 was $2.6 million, or $0.05 per diluted share.

On a GAAP basis, operating loss for the fourth quarter 2007 was $419,000 and for the fiscal year ended June 30, 2007 was $8.5 million. On a non-GAAP basis which excludes non-cash stock-based compensation charges, operating income was $3.4 million for the fourth quarter of fiscal 2007 and $4.1 million for the fiscal year ended June 30, 2007.

At the end of fiscal 2007, backlog increased to approximately $619 million, with approximately $321 million associated with CyberKnife® System contracts and approximately $298 million associated with services and other recurring revenue. Backlog is defined as signed contracts that the Company believes have a substantially high probability of being booked as revenue.

Services revenue for the fiscal fourth quarter of 2007 was $5.7 million compared with $1.8 million during the fourth quarter in 2006, a 217 percent increase. Full fiscal year 2007 services revenue was $16.9 million, a 248 percent increase over the $4.8 million reported for fiscal year 2006.

“The Accuray team and I are very pleased with our strong financial performance, including record revenue, fourth quarter profitability and record backlog. Accuray’s clinical programs and R&D efforts are rapidly expanding utilization of the CyberKnife System, fueling the impressive momentum that Accuray is experiencing today,” said Euan S. Thomson, Ph.D., president and chief executive officer of Accuray, Incorporated. “The CyberKnife System is the established brand leader in the rapidly expanding radiosurgery market. Its dramatic growth in extracranial usage, particularly for lung and prostate tumors, is driving greater acceptance among the medical community. Our strong fourth quarter provides solid momentum as we start an exciting new fiscal year.”

At the end of fiscal 2007, the Company had increased its cash position to $204.8 million.
