"Led by strong margins, we were able to deliver operating profits in 2011 despite delays related to a key component that caused a large acceptance to slip out beyond year-end, but which we have since completed", stated Peter Ungaro, president and CEO of Cray. "We continue to see strength in our high-end supercomputer business with a number of big wins over the past few months, both domestically and abroad. We are making good progress on our three growth initiatives with new offerings in each planned for 2012. These initiatives leverage our core strengths in supercomputing while dramatically expanding our addressable market and growth potential. I expect 2012 to be an outstanding year for the company, breaking the $400 million revenue threshold and refreshing our entire product line top to bottom."
While a wide range of results remains possible for 2012, the company expects 2012 revenue to be in the range of $400-$420 million. Revenue for the first quarter of 2012 is expected to be about $100 million with the balance of the revenue for the year heavily weighted to the fourth quarter. Overall gross margins for 2012 are anticipated to be in the 35 percent range. Total operating expenses for the year are expected to increase to about $120 million, driven primarily by higher investments in our growth initiatives and incentive based compensation. Based on this outlook, Cray expects to be solidly profitable for 2012.
As a result of the partial release of the deferred tax valuation allowance in the fourth quarter of 2011, while volatile and dependent on a number of variables, the company currently projects its 2012 effective income tax rate to be about 40 percent. Due to the company's substantial net operating loss carryforwards the quarterly and annual income tax provision is expected to be largely non-cash.
Actual results for any future period are subject to large fluctuations given the nature of Cray's business.
