NEWS RELEASE April 30, 2008

Operating expenses in the quarter were $10.2 million, up slightly from $10.1 million in the previous quarter and up from $9.4 million in the comparable period last year. Operating expenses in the nine-month period ending March 29, 2008 were $30.2 million, up from $28.1 million in the comparable period last year. Stock-based compensation expense in the quarter was $585,000, down from $650,000 in the previous quarter and up from $443,000 in the comparable period last year. Stock based compensation expense for the nine-month period ended March 29, 2008 was $1.7 million, up from $1.5 million in the comparable prior year period.

Net income in the quarter was $4.1 million, or $0.16 per diluted share, compared with net income of $4.4 million, or $0.16 per diluted share in the second quarter and net income of $2.6 million, or $0.10 per diluted share, in the same period a year ago. Net income in the nine-month period ending March 29, 2008 was $12.4 million, or $0.47 per diluted share, up from $6.5 million, or $0.24 per diluted share in the comparable prior year period.

“Continued strength in high-growth end markets, especially in digital video and high-performance PCs and servers, allowed us to achieve strong financial results during the quarter,” said Alex Hui, President and Chief Executive Officer. “Revenues from high-speed serial protocol solutions increased 80% sequentially and accounted for 9% of total revenue.”

“While the broader consumer spending environment has become increasingly challenging, our design win pipeline is strong and we believe our products position us well to sustain revenue and earnings growth going forward. We believe that our end markets are in the early stages of high growth phases and accordingly, are less affected by consumer spending patterns,” concluded Hui.

New Products

Expanding on our Digital Video solutions, Pericom launched two 'Industry First' products using both PCI Express® Gen2 and the new DisplayPort’ technologies. The two new switches allow next generation computing platforms using dual function (both PCIe Gen2 and DP) graphics ports to be switched between either of the high speed protocols, enabling PC manufacturers to build just one, rather than two, base motherboards.

Continuing our focus on Serial Signal Conditioning, Pericom launched three new HDMI signal conditioning products targeting consumer and computing platforms such as DTV and PC using HDMI signaling. This new ReDriver product family enables marginal HDMI/DVI designs to now pass compliance testing easily, thus speeding time to market and lowering overall design costs.

NEWS RELEASE April 30, 2008

Further expanding our Timing portfolio, Pericom introduced a very low jitter (<0.2ps) clock oscillator/buffer, targeted to Gigabit Ethernet applications in communications and computing market segments. The new product provides exceptionally good performance in multi-port switches, where a very low clock jitter source is essential to good performance.

Share Repurchase Update

In April 2007, Pericom's board of directors authorized a share repurchase program to buy up to 2.0 million shares of its common stock. During the quarter, the Company spent approximately $14.9 million to repurchase approximately 1.09 million shares of Pericom common stock at an average price of $13.68. The company has purchased a total of approximately 1.86 million shares under this program at an average price of $12.49.

Fiscal Q4 Outlook

The following statements are based on current expectations. These statements are forward looking, and actual results may differ materially.

·	Revenues in the fourth fiscal quarter are expected to be in the range of $42.0 million to $43.2 million.

·	Gross margins are expected to be in the 36.8 to 37.8 percent range. Margins are influenced by the product mix of turns business and sales, if any, of previously reserved inventory.
