AMD reported first quarter 2007 revenue of $1.233 billion, an operating loss of $504 million, and a net loss of $611 million. These results include ATI acquisition-related and integration charges of $113 million, or $0.21 per share, and employee stock-based compensation expense of $28 million, or $0.05 per share. In the fourth quarter of 2006, AMD reported revenue of $1.773 billion and an operating loss of $529 million. In the first quarter of 2006, AMD reported revenue of $1.332 billion and operating income of $259 million. "After more than three years of successfully executing our customer expansion strategy and significantly growing our unit and revenue base, our first quarter performance is disappointing and unacceptable," said Robert J. Rivet, AMD’s chief financial officer. "We are aggressively addressing the issues that led to our significant revenue decline. We are aligning our business model, capital expenditures and cost structure with the goal of accelerating our return to profitability. Lastly, our customer relationships remain solid, reflecting their confidence in our strategic direction, current and new products, and technology roadmaps." First quarter 2007 gross margin was 31 percent, excluding stock-based compensation expense and acquisition-related charges, compared to 40 percent in the fourth quarter of 2006 and 59 percent in the first quarter of 2006. The decrease from the prior quarter was largely due to significantly lower microprocessor unit shipments, lower microprocessor average selling prices (ASPs), and the inclusion of the former ATI operations, which generally have lower-margin products, for the entire quarter.
