Service revenue is projected to be about $5 million and license and royalty revenue are expected to be about $1 million. We are clearly disappointed with our revenue this quarter, said Tim Barabe, executive vice president and CFO.

During the second quarter we experienced decreased sales to academic customers across all regions, particularly in North America. Our consumable revenue was down by about 10% from last year, said Andrew Last, Affymetrix executive vice president and chief commercial officer. The company will report second quarter financial results after the close of the market on July 27.

The company lowered its second quarter revenue guidance to about $71 million from previous forecast of $75.5 million to $78.5 million, while Street predicts $77.05 million. The company reduced its revenue guidance due to lower-than-expected Micro-electronics revenue, and lower shipments of DRAM units during the first quarter. We recognize Micro-electronics revenue one quarter in arrears and the first quarter actual data came in lower than expectations, which impacted our second quarter financials, said Robert Young, chief executive officer and president, Tessera.
