(Nasdaq: PDFS) the leading provider of process-design integration technologies to enhance IC manufacturability, today announced financial results for its first fiscal quarter ended March 31, 2004. Revenue for the first fiscal quarter of 2004 totaled a record $12.7 million, an increase of 40%, compared with revenue of $9.1 million for the first fiscal quarter of 2003. On a GAAP basis, net loss for the first fiscal quarter of 2004 totaled $1.8 million, or $0.07 per diluted share, compared with a net loss of $1.3 million, or $0.06 per diluted share, for the first fiscal quarter of 2003. In addition to using GAAP results in evaluating PDF's business, management also believes it useful to measure results using a non-GAAP measure of net income (loss), which excludes amortization of stock-based compensation and acquired intangible assets. Using this non-GAAP measure, net loss for the first fiscal quarter of 2004 totaled approximately $373,000, or $0.01 per diluted share, compared with a non-GAAP net loss of approximately $658,000, or $0.03 per diluted share, for the first fiscal quarter of 2003. As previously announced, the company will hold a live conference call beginning at 3:00 p.m. PDT/6:00 p.m. EDT today to discuss the quarterly results. A live webcast of this conference call will be available on the company's website at http://ir.pdf.com/medialist.cfm. A replay of the call will be available at the same website address beginning approximately two hours after completion of the live call. Further, a copy of this press release, including the disclosure and reconciliation of certain non-GAAP financial measures to the most directly comparable GAAP measure, which non-GAAP measures may be used periodically by the company's management when discussing financial results with investors and analysts, will be available on the company's website at http://www.pdf.com/news_archive.phtml following the date of this release.
