reported in the comparable period last year. Net income in the quarter was $2.3

"We are very pleased to have reported a strong sequential increase in both
operating and net profit this quarter," said Alex Hui, president and chief

comparison with the same quarter of last year, through the increasing adoption
of our high-speed serial connectivity solutions for USB, Gigabit Ethernet,
wireless LAN, HDMI and PCI-Express applications. We expect to sustain this

  Q2 NEW PRODUCTS

the industry's only PCIe 1.1 compliant bridge to receive PCISIG certification to
date. Target applications include servers, HBA and NIC cards, networking,

and digital TVs,  further  enhancing  Pericom's  product  positioning in digital
video platforms.

FISCAL Q3 2007 OUTLOOK

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

     o    The company continues to be in a high turns environment and therefore
          revenue visibility remains limited. Depending upon the strength of
          turns orders, revenues in the third fiscal quarter are expected to be
          in the range of $29.5 million to $31.0 million. Gross margins are
          expected to be in the 35 to 36 percent range. Margins are influenced
          by the product mix of turns business and sales, if any, of previously
          written down inventory.
     o    Operating expenses are expected to be in the range of $9.3 to $9.8
          million.
     o    Other income is expected to be approximately $1.1 million, consisting
          primarily of interest income.
     o    Equity in net income (loss) of investees is expected to be
          approximately $100,000.
