RALEIGH, N.C.--(BUSINESS WIRE)--March 23, 2011--Red Hat, Inc. (NYSE: RHT), the world's leading provider of open source solutions, today announced financial results for its fiscal fourth quarter and fiscal year ended February 28, 2011.

Total revenue for the quarter was $244.8 million, an increase of 25% from the year ago quarter. Subscription revenue for the quarter was $209.3 million, up 24% year-over-year. For the full year, total revenue was $909.3 million, an increase of 22% over the prior year, and subscription revenue was $773.4 million, up 21% year-over-year.

“With record bookings and billings in the fourth quarter, we are on a run rate to become the first pure-play open source company to achieve a billion dollars in revenues next fiscal year, a milestone achievement for Red Hat and the open source community,” stated Jim Whitehurst, President and Chief Executive Officer of Red Hat. “We believe the strong demand we experienced was largely driven by customers who are modernizing their data centers and preparing their infrastructure for cloud computing. The comprehensive portfolio that Red Hat has developed with platform, virtualization and middleware products provides enterprise customers with a foundation to deploy the next generation infrastructure.”

GAAP operating income for the fourth quarter and the full fiscal year 2011 was $39.4 million and $145.7 million, respectively. GAAP operating margin was 16.1% in the fourth quarter and 16.0% for the full year. After adjusting for stock compensation, amortization expenses, and in the prior year, the charge for a litigation settlement as detailed in the tables below, non-GAAP operating income for the quarter was $61.0 million, or a 24.9% operating margin, and full year non-GAAP operating income was $225.2 million. Full year non-GAAP operating margin was 24.8%, representing an increase of 110 basis points from the prior year.

GAAP net income for the fourth quarter was $33.5 million, or $0.17 per diluted share, compared with $26.0 million, or $0.13 per diluted share, for the prior quarter and $23.4 million, or $0.12 per diluted share, in the year ago quarter. Non-GAAP adjusted net income for the fourth quarter was $51.4 million, or $0.26 per diluted share, after adjusting for stock compensation and amortization expenses as detailed in the tables below. This compares to non-GAAP adjusted net income of $39.1 million, or $0.20 per diluted share in the prior quarter and $36.5 million, or $0.19 per diluted share in the year ago quarter.

For the full year, GAAP net income was $107.3 million or $0.55 per diluted share, compared with $87.3 million or $0.45 per diluted share in the prior year. After adjusting for stock compensation, amortization expenses, and in the prior year, the charge for a litigation settlement, as detailed in the tables below, non-GAAP adjusted net income for the year was $162.8 million or $0.83 per diluted share, compared to $138.1 million and $0.71 per diluted share for the fiscal year ended February 28, 2010.

Fourth quarter GAAP and non-GAAP net income benefited by approximately $0.02/share as a result of the retroactive reenactment in December 2010, of the research tax credit into US tax law. This, together with other tax benefits, including additional US foreign tax credits, reduced the fourth quarter fiscal 2011 effective tax rate for both GAAP and non-GAAP to 17%. The resulting full year effective tax rate for both GAAP and non-GAAP for fiscal 2011 is 30%.

GAAP operating cash flow totaled $95.0 million for the fourth quarter and $290.7 million for the full year. At year end, the company’s total deferred revenue balance was $772.3 million, an increase of 20% on a year-over-year basis and 13% sequentially. Cash and investments at February 28, 2011 totaled $1.2 billion after repurchasing approximately $11 million, or approximately 250,000 shares, of common stock in the quarter. For the full fiscal year, Red Hat repurchased approximately $90 million, or 2.9 million shares, of common stock.

“Our fourth quarter results were strong and capped off a year of accelerated billings growth. Broad- based, global demand for our products and services, coupled with strong execution by our associates, resulted in over 30% year-over-year growth in billings this quarter; our fastest billings growth in 12 quarters,” stated Charlie Peters, Executive Vice President and Chief Financial Officer of Red Hat. “This year we focused on growth with aggressive hiring for sales and engineering, launched major product releases and invested in technologies focused on cloud computing. These investments produced greater than 20% growth in revenues and non-GAAP operating income for both the quarter and the year. At the same time, we increased non-GAAP operating margins by 110 basis points and improved cash flow. It was a good year.”
