Semtech Corp. said late Monday that a Nasdaq panel has postponed a decision to delist its shares because of its inability to file financial reports as the company reviews its stock option practices.

The Camarillo-based microchip maker announced in May that it had received a letter of informal inquiry from the Securities and Exchange Commission seeking information related to stock options granted since Jan. 1, 1997. It is one of nearly 200 public companies reviewing possible backdating of stock options to maximize executive gains.

The company later said it would restate its financial results for fiscal years 2002 through 2006 to record additional material stock compensation expenses uncovered by its inquiry. The company had until Monday to file the restatements and regain compliance with the Nasdaq’s listing requirements, but it missed the deadline.

Semtech said it will release fiscal third-quarter 2007 revenue and other selected results after the closing bell on Nov. 30.

Semtech shares were off 2 cents to $12.54 in early trading Tuesday.
