MILPITAS, CA--(Marketwired - Nov 18, 2015) - Pericom Semiconductor Corporation ("Pericom" or the "Company") (NASDAQ: PSEM) announced today that its Board of Directors issued an open letter to Pericom shareholders urging them to take advantage of the opportunity to lock in a substantial and near-certain premium by voting the WHITE proxy card "FOR" the Agreement and Plan of Merger between Diodes Incorporated ("Diodes") (NASDAQ: DIOD) and Pericom, dated September 2, 2015, as amended November 5, 2015 (the "Diodes Merger Agreement"). The Company's Special Meeting of Shareholders is scheduled for November 20, 2015.

The full text of the letter is as follows:

November 18, 2015

Dear Shareholders,

As you know, our Special Meeting of Shareholders (the "Special Meeting") will be held on Friday, November 20, 2015 at 9:00 a.m. PT. The Special Meeting is being called primarily to seek shareholder approval of the acquisition of Pericom by Diodes Incorporated ("Diodes") (NASDAQ: DIOD), pursuant to the Agreement and Plan of Merger between Diodes and Pericom, dated September 2, 2015, as amended November 5, 2015 (the "Diodes Merger Agreement" or the "Agreement").

With the Special Meeting only days away, it is urgent that you vote on the WHITE proxy card "FOR" the Diodes Merger Agreement, which will ensure your prompt receipt of the $17.75 per share cash purchase price offered by Diodes. This purchase price represents a 46% premium to the per share closing price of Pericom shares on September 2, 2015, exceeds the five-year trading high in Pericom shares by 8%, and is backed by a rock-solid, fully-funded term loan from a U.S. bank. Subject only to your approval at the Special Meeting, the Diodes transaction offers not only a substantial per share cash premium, but also near-term closing certainty -- the value of which cannot be discounted.

TIME IS SHORT - RECEIVE CERTAIN AND SUBSTANTIAL CASH IN DAYS - VOTE THE WHITE PROXY
CARD "FOR" A TRANSACTION WITH DIODES BY PHONE OR INTERNET TODAY!

Pericom's upcoming Special Meeting is only a few days away, and it is important for you to take action promptly to achieve what your Board believes is the best outcome for Pericom's shareholders. Pericom's Board and senior management team collectively own more than 10% of Pericom's outstanding shares, and our interests in achieving the best possible outcome are fully aligned with your interests. Thus, the Pericom Board continues to unanimously recommend that you vote "FOR" the Diodes Merger Agreement on the WHITE proxy card -- a recommendation that is strongly supported by three leading independent proxy advisory firms.

Time remains to vote your shares and lock in the substantial premium that would be realized upon the prompt closing of the Diodes Merger Agreement. You may vote the WHITE proxy card by telephone or internet at any time leading up to the Special Meeting. If you have already voted a different color proxy card, you can change your vote by internet or phone using the information on your WHITE proxy card -- only your latest dated proxy card will be counted.

If you have any questions or need assistance voting "FOR" the Diodes Merger Agreement on the WHITE proxy card, please call Mackenzie Partners, Inc., Pericom's proxy solicitor, at (212) 929-5500 or toll free at (800) 322-2885.

We thank you for your continued support of Pericom and hope to see you at Friday's Special Meeting.

Regards,
Pericom Semiconductor Corporation Board of Directors
