SVB FINANCIAL GROUP UPDATES STATUS OF FORM 10-Q FILING FOR SECOND QUARTER

SANTA CLARA, Calif. — August 9, 2005 — SVB Financial Group (Nasdaq: SIVB) today filed with the Securities and Exchange Commission a notice of late filing on Form 12b-25 with respect to its quarterly report on Form 10-Q for the fiscal quarter ended June 30, 2005. Due to changes in the Company’s accounting treatment for warrants dating back to the third quarter of 2001, the Company indicated in the notice that the Form 10-Q for the second quarter would not be filed by the prescribed due date of August 9, 2005, and that the Company did not expect that it would be filed within five days after such due date, as provided under Rule 12b-25 of the Securities Exchange Act of 1934, as amended. The Company currently expects that the Form 10-Q will be filed during the third calendar quarter of 2005.

As previously disclosed, the Company plans to restate its consolidated financial statements for the years 2001, 2002, 2003 and 2004, and the first quarter of 2005, due to a revision in the accounting treatment for its portfolio of unexercised warrant securities in privately-held companies. For more information about this revision, refer to SVB Financial Group’s news release on this matter dated July 21, 2005.

The Company intends to file amendments to its Annual Report on Form 10-K for the year ending December 31, 2004 and its Quarterly Report on Form 10-Q for the quarter ending March 31, 2005, shortly before or simultaneously with the filing of its Quarterly Report on Form 10-Q for the quarter ended June 30, 2005.
