On June 13, 2016, Mohan Maheswaran, President, Chief Executive Officer and a Director of Semtech Corporation (the “Company”), entered into a written pre-arranged stock trading plan in accordance with guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934 for the sale of a maximum of 18,000 shares of the Company’s common stock. The plan provides for sales of specified numbers of such shares on the open market at prevailing prices on the applicable trading days specified under the plan, subject to a minimum price threshold as specified in the plan.  The plan provides for sales beginning in August 2016 and ending in July 2017.

The plan is consistent with, and will follow, a similar plan entered into by Mr. Maheswaran in April 2015, which expired following the final trade under that plan in March 2016.

Except as may be required by law, the Company does not undertake to report Rule 10b5-1 trading plans established by any other Company employees, officers or directors, nor to report modifications, terminations, or other activities under any publicly announced trading plan.
