PDF Solutions Reports Third Quarter 2007 Results

Quarterly Gain Share a Strong Contributor to Overall Revenue Growth


SAN JOSE, Calif., Oct. 31, 2007 (PRIME NEWSWIRE) -- PDF Solutions, Inc. (Nasdaq:PDFS) the leading provider of yield improvement technologies and services for the integrated circuit (IC) manufacturing process lifecycle, today announced financial results for its third fiscal quarter ended September 30, 2007.

Revenue for the third fiscal quarter of 2007 totaled $24.1 million, an increase of 24%, compared with revenue of $19.4 million for the third fiscal quarter of 2006. Gain share revenue for the third fiscal quarter of 2007 totaled $6.8 million, an increase of 55%, compared to $4.4 million for the third fiscal quarter of 2006. On a GAAP basis, net loss for the third fiscal quarter of 2007 totaled approximately $939,000, or $0.03 per basic share, compared with net income of approximately $570,000, or $0.02 per basic and diluted share, for the third fiscal quarter of 2006.

In addition to using GAAP results in evaluating PDF Solutions' business, management also believes it is useful to measure results using a non-GAAP measure of net income, which excludes stock-based compensation expense, amortization of acquired intangible assets and their related income tax effects. Using this non-GAAP measure, net income for the third fiscal quarter of 2007 totaled approximately $5.3 million, or $0.19 per diluted share, compared with non-GAAP net income of approximately $3.6 million, or $0.13 per diluted share, for the third fiscal quarter of 2006.

Additionally, during the third quarter ended September 30, 2007, PDF Solutions utilized the remaining balance available under the $10 million share repurchase plan previously authorized by its Board of Directors. During the quarter, PDF Solutions repurchased 437,287 of its shares on the open market at a weighted average cost of $10.18, for a total repurchase value of approximately $4.5 million. On October 29, 2007, PDF Solutions' Board of Directors authorized an additional $10.0 million share repurchase, to be utilized over the upcoming three years.

As previously announced, PDF will discuss these results on a live conference call beginning at 3:00 p.m. Pacific Time/6:00 p.m. Eastern Time today. The call will be simultaneously web cast on PDF Solutions' website at http://ir.pdf.com/medialist.cfm. A replay of the web cast 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 comparable GAAP measure, which non-GAAP measures may be used periodically by PDF Solutions' management when discussing financial results with investors and analysts, will be available on PDF Solutions' website at http://www.pdf.com/news_archive.phtml following the date of this release.

Information Regarding Use of Non-GAAP Financial Measures

In addition to providing results that are determined in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP), PDF Solutions also provides certain non-GAAP financial measures that exclude the effects of stock-based compensation expense, amortization of acquired intangible assets, and their related income tax effects. PDF Solutions' management believes that the presentation of these measures provides useful supplemental information to investors regarding PDF's operating results. These non-GAAP financial measures are used by management internally to measure the company's profitability and performance. PDF's management believes that excluding the effects of stock-based compensation expense, amortization of acquired intangible assets, and their related income tax effects, provides a useful supplemental measure of the company's ongoing operations in light of the fact that neither category of expense has a current effect on the future uses of cash nor do they have use with regards to the generation of current or future revenues. These non-GAAP results should not be considered an alternative to, or a substitute for, GAAP financial information, and may be different from similarly titled non-GAAP measures used by other companies. In particular, these non-GAAP financial measures are not a substitute for GAAP measures of income as a measure of performance, or to cash flows from operating, investing and financing activities as a measure of liquidity. Since management uses these non-GAAP financial measures internally to measure profitability and performance, PDF has included these non-GAAP measures to give investors an opportunity to see the company's financial results as viewed by management. A reconciliation of the non-GAAP financial measures to the comparable GAAP financial measure is provided at the end of the company's financial statements presented below.
