Exhibit 99.1

Cohu Reports First Quarter 2014 Operating Results

POWAY, Calif., April 30, 2014 — Cohu, Inc. (NASDAQ:COHU) today reported fiscal 2014 first quarter net sales of $68.4 million and GAAP net loss of $3.3 million or $0.13 per share. The Company also reported non-GAAP results, with first quarter 2014 net income of $0.5 million or $0.02 per share.

Sales of semiconductor equipment accounted for 88% of fiscal 2014 first quarter sales. Microwave communications and video equipment contributed 7% and 5%, respectively, for the same period.

Orders were $81.6 million for the first quarter of 2014 and $76.0 million for the fourth quarter of 2013. Orders for semiconductor equipment were $74.3 million in the first quarter of 2014 compared to $68.3 million in the fourth quarter of 2013. Total consolidated backlog was $101.6 million at March 29, 2014 compared to $88.4 million at December 28, 2013. Cohu expects second quarter 2014 sales of $72 million to $80 million.

James A. Donahue, Chairman, President and Chief Executive Officer stated, “Cohu’s first quarter 2014 sales were above our guidance. The order momentum that began late last year continued to build throughout Q1 and demand for our semiconductor equipment was broad based across market segments and customers.”

Donahue concluded, “We are benefitting from improved conditions in the backend semiconductor industry, competitive wins driven by our new products and from cross selling synergies among our three IC handler businesses. First quarter financial results reflect favorable product mix, initial benefits from the transition of manufacturing to Asia and lower operating expenses, primarily due to product development programs that have concluded or are nearing completion, as planned.”

Use of Non-GAAP Financial Information:

Included within this press release are non-GAAP financial measures that supplement the Company’s Condensed Consolidated Statements of Operations prepared under generally accepted accounting principles (GAAP). 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, the amortization of acquired intangible assets, manufacturing transition costs, employee severance costs, other acquisition costs and the purchase accounting inventory step-up included in cost of goods sold. Reconciliations of GAAP to non-GAAP amounts for the periods presented herein are provided in schedules accompanying this release and should be considered together with the Condensed Consolidated Statements of Operations.

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 Cohu’s financial performance using some of the same measures as management. However, the non-GAAP financial measures should not be regarded as a replacement for (or superior to) corresponding, similarly captioned, GAAP measures.

Forward-Looking Statements:

Certain matters discussed in this release, including statements regarding expectations of business and market conditions, orders, sales, revenues and operating results are forward-looking statements that are subject to risks and uncertainties that could cause actual results to differ materially from those projected or forecasted. Such risks and uncertainties include, but are not limited to, risks associated with acquisitions, inventory, goodwill and other intangible asset write-downs; our ability to convert new products under development into production on a timely basis, support product development and meet customer delivery and acceptance requirements for next generation equipment; our reliance on third-party contract manufacturers; failure to obtain customer acceptance resulting in the inability to recognize revenue and accounts receivable collection problems; customer orders may be canceled or delayed; the concentration of our revenues from a limited number of customers; intense competition in the semiconductor test handler industry; our reliance on patents and intellectual property; compliance with U.S. export regulations; and the cyclical and unpredictable nature of capital expenditures by semiconductor manufacturers. These and other risks and uncertainties are discussed more fully in Cohu’s filings with the Securities and Exchange Commission, including the most recently filed Form 10-K and Form 10-Q. Cohu assumes no obligation to update the information in this release.

Supplemental Reconciliation of GAAP Results to Non-GAAP Financial Measures (Unaudited)

(in thousands, except per share amounts)

Management believes the presentation of these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provides meaningful supplemental information regarding the Company’s operating performance. Our management uses these non-GAAP financial measures in assessing the Company’s operating results, as well as when planning, forecasting and analyzing future periods and these non-GAAP measures allow investors to evaluate the Company’s financial performance using some of the same measures as management. Management views share-based compensation as an expense that is unrelated to the Company’s operational performance as it does not require cash payments and can vary in amount from period to period and the elimination of amortization charges provides better comparability of pre and post-acquisition operating results and to results of businesses utilizing internally developed intangible assets. Manufacturing transition costs relate principally to employee severance expenses incurred as a result of moving certain manufacturing activities to Asia as part of our cost reduction efforts and employee severance are costs incurred in conjunction with the termination of certain employees to streamline our operations and reduce costs. Management has excluded these costs primarily because they are not reflective of the ongoing operating results and they are not used to assess ongoing operational performance. Other acquisition costs and inventory step-up have been excluded by management as they are unrelated to the core operating activities of the Company and the frequency and variability in the nature of the charges can vary significantly from period to period. Excluding this data provides investors with a basis to compare Cohu’s performance against the performance of other companies without this variability. However, the non-GAAP financial measures should not be regarded as a replacement for corresponding, similarly captioned, GAAP measures. The presentation of non-GAAP financial measures above may not be comparable to similarly titled measures reported by other companies and investors should be careful when comparing our non-GAAP financial measures to those of other companies.
