"We had a solid first quarter as we continued our strong run of new wins, including at Petroleum Geo-Services, which selected an XC40 and Cray storage to power its most advanced seismic imaging efforts", stated Peter Ungaro, president and CEO of Cray. "We also installed our first XC supercomputer in Poland at Stalprodukt, a leading advanced steel manufacturer. Looking toward the future, we recently outlined our plans for our next-generation supercomputer, code-named 'Shasta', targeted for 2018. A Shasta-based system was selected by Argonne National Laboratory along with Cray storage and an XC system for the Department of Energy's CORAL project, and we're excited to be partnering with Intel to deliver these powerful new systems. This is a significant validation of our product roadmap as Shasta will deliver on our Adaptive Supercomputing vision to bridge the world of supercomputing with data analytics."
The company anticipates revenue for 2015 to be in the range of $715 million. Revenue is expected to ramp quarterly during 2015, with about $130 million in the second quarter and roughly 40-45% of the total year in the fourth quarter.
