said late Wednesday it will delay filing its first-quarter report due to an informal inquiry of its stock option practices by the

Securities and Exchange Commission

The Camarillo, Calif.-based chip company last week had asked that the due date be extended to June 14.

Semtech also said that two separate stockholder derivative lawsuits have been filed against it related to stock option practices. Additionally, on June 13, the company received a grand jury subpoena from the U.S. District Court, Southern District of New York, with respect to the production of documents relating to its stock option practices.

Shares were down 39 cents, or 2.6%, at $14.40 in recent trading Thursday.
