CRAY INC. REPORTS 2010 FULL YEAR AND FOURTH QUARTER

RESULTS

Company posts strong profitability and record annual revenue

Seattle, WA – February 16, 2011 – Global supercomputer leader Cray Inc. (Nasdaq GM: CRAY) today announced 2010 financial results for the full-year and fourth quarter. For 2010, Cray reported record revenue of $319.4 million and net income of $15.1 million, or $0.43 per share. For 2009, revenue was $284.0 million and net loss was ($0.6 million), or ($0.02) per share.

Revenue for the fourth quarter of 2010 was $219.4 million compared to $88.2 million in the fourth quarter of 2009. The Company reported net income for the fourth quarter of 2010 of $52.1 million, or $1.46 per share, compared to $3.0 million, or $0.08 per share, in the fourth quarter of 2009.

Overall gross profit margin for 2010 was 34 percent compared to 37 percent in 2009. Product margin for 2010 was 35 percent compared to 34 percent in 2009 and service margin for 2010 was 32 percent compared to 44 percent for 2009. For the fourth quarter of 2010, overall gross profit margin was 37 percent compared to 41 percent in the fourth quarter of 2009.

Operating expenses for 2010 decreased to $92.5 million compared to $106.1 million in 2009. 2010 operating expenses benefited from higher R&D co-funding credits related to the Company’s DARPA contract. Included in the 2010 results were $9.4 million for depreciation and amortization and $4.9 million related to stock compensation.

Operating expenses for the fourth quarter of 2010 were $27.4 million compared to $33.7 million in the prior year period. Included in the fourth quarter 2010 results were non-cash items of $2.6 million for depreciation and amortization and $1.3 million related to stock compensation.

As of December 31, 2010, cash balances totaled $61.3 million and accounts receivable totaled $106.3 million.

“2010 was a remarkable year for the company and I am extremely pleased with our results,” said Peter Ungaro, president and CEO of Cray. “We grew revenue for a third straight year and posted strong profits – both significant achievements of which we are all very proud. Our Custom Engineering business remained on a fast growth pace in 2010, more than doubling revenue over 2009. We launched the Cray XE6 supercomputer in

mid-2010 and total orders for the system have now exceeded over $300 million. I am especially pleased with our execution in 2010 as we successfully developed an industry-leading supercomputer, built and installed a record number of systems over a six-month period, and achieved all of the acceptances necessary to make 2010 a record year.”

Ungaro added, “Our focus now shifts to delivering on our strategic plans for 2011. With two major enhancements planned for the Cray XE6 line and continued momentum in Custom Engineering, we are positioned for continued growth in 2011.”

Outlook

While a wide range of results remains possible for 2011, total revenue for the year is anticipated to be in the range of $320 to $340 million. Revenue in the first quarter of 2011 is expected to be approximately $35 to $40 million, and revenue is expected to ramp through the third quarter with approximately half of the annual revenue being recognized in the fourth quarter. For the year, gross margins are expected to be in the range of 2010 levels and operating expenses are expected to be higher than 2010, driven primarily by lower anticipated R&D co-funding credits. Based on this outlook, we expect to be profitable for 2011.

Cash balances are expected to increase significantly from fourth quarter levels by the end of the first quarter of 2011.

Actual results for any future period are subject to large fluctuations given the nature of Cray’s business.

Recent Highlights

• In November, Cray announced the launch of the Cray XE6m – the latest addition to the Company’s line of Cray XE supercomputers. This midrange version of the Cray XE6 system includes the same innovative features and technologies of the Gemini-based supercomputers while offering both new and existing customers the same functionality at a lower entry point.

• Cray announced several new wins in the university segment during the fourth quarter expanding a growing, worldwide list of academic institutions that have purchased Cray supercomputers. New universities include the City University of New York, George Washington University in Washington D.C., Yokohama City University in Japan, Colorado State University, University of Chicago and University of Stuttgart.

• In the fourth quarter, Cray signed multiple Custom Engineering contracts valued at a combined total of more than $12 million. The various contracts were signed across all three Custom Engineering practices—special purpose systems, knowledge management and data management.

• At the 2010 Supercomputing Conference held in New Orleans, Louisiana, Cray’s new Gemini interconnect was named “Best HPC Interconnect Product or

2

Technology” by the editors of HPCwire. The Cray XE6 and Cray XE6m supercomputers include a mix of features and performance designed specifically for the petascale environment, and it is all made possible by Cray’s Gemini interconnect. Cray is honored to achieve this prestigious award, which is reflective of all the hard work by Cray employees company-wide.

• During the fourth quarter, Cray joined Data Direct Networks, Lawrence Livermore National Laboratory and Oak Ridge National Laboratory in launching Open Scalable File Systems, Inc. (OpenSFS) – a technical organization focused on high-end, open-source file system technologies. This includes Lustre which plays an important role for Cray customers who need high performance I/O capabilities.

• In early 2011, Cray appointed Larry Hoelzeman to the position of vice president of worldwide sales. Hoelzeman previously was vice president of Americas sales and will also continue in that role with the Company.
