Item 2.02 Results of Operations and Financial Condition.

On April 25, 2012, Cohu, Inc. (the “Company”) issued a press release regarding its financial results for the first quarter ended March 31, 2012. The Company’s press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein.

The information in this Item 2.02 of this Current Report on Form 8-K and the Exhibit attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of any general incorporation language in such filing.

In addition to financial results determined in accordance with generally accepted accounting principles (“GAAP”), the earnings press release also contains financial information determined by methods other than in accordance with GAAP. The Company’s management uses these non-GAAP measures in their analysis of the Company’s performance. These non-GAAP financial measures adjust the Company’s actual results prepared under GAAP to exclude charges and the related income tax effect for share-based compensation and the amortization of acquired intangible assets. These non-GAAP measures are not meant as a substitute for GAAP, but are included solely for informational and comparative purposes. The Company’s management believes that this information can assist investors in evaluating the Company’s operational trends, financial performance, and cash generating capacity. Management believes these non-GAAP measures allow investors to evaluate the Company’s financial performance using some of the same measures as management. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

Shay Torton, Senior Vice President, Operations of Cohu, Inc.’s wholly owned subsidiary Delta Design, Inc. (“Delta”), will be resigning effective May 17, 2012.
