Exhibit 99.1

Cohu, Inc.

Unaudited Pro Forma Condensed Consolidated Financial Statements

Description of Transaction

On June 10, 2015, Cohu, Inc. (referred to as “Cohu”, “we” and “our”) announced that we entered into a Stock Purchase Agreement (the “Purchase Agreement”) with an affiliate of StoneCalibre, LLC (“StoneCalibre”), a privately funded investment firm headquartered in Century City, California, pursuant to which StoneCalibre through its affiliate acquired all of the outstanding stock of Cohu’s wholly owned subsidiary Broadcast Microwave Services, Inc. (“BMS”), herein referred to as the “Transaction”. BMS develops, manufactures and sells mobile microwave communications equipment to government agencies, law enforcement, public safety organizations and other commercial entities.

Under the terms of the Purchase Agreement, the total sale price was $8.0 million, comprised of a $5.5 million cash payment on closing plus up to $2.5 million of contingent cash consideration in the form of an earn-out based on future BMS revenues over the two-year calendar period ending December 2017. The final purchase price is subject to a net working capital adjustment to be settled following the closing and the final valuation of the contingent consideration which may result in adjustments to the loss on sale recognized in the second quarter of 2015 that is currently estimated to be approximately $3.0 million. In connection with the closing of the transaction, BMS entered into a twelve-month lease, subject to certain early termination rights, with Cohu that enables the business to continue to operate at its current location in Poway, California.

The unaudited pro forma condensed consolidated balance sheet presents our historical financial position as if the Transaction occurred on March 28, 2015, and the unaudited pro forma condensed consolidated statements of operations were prepared as if the Transaction occurred on January 1, 2012. The accompanying unaudited pro forma condensed consolidated financial statements are provided for informational purposes only and are not necessarily indicative of the consolidated financial position or results of operations of Cohu that would have been reported had the sale been completed at the dates indicated herein nor are they indicative of Cohu’s future consolidated financial position or results of operations. Amounts reported in future financial statements with the Securities and Exchange Commission (“SEC”) for the periods presented herein could differ from these pro forma condensed consolidated financial statements. Accordingly, the historical consolidated financial information has been adjusted to give effect to the impact of the consideration received in connection with the Transaction and to give effect to pro forma events that are (i) directly attributable to the Transaction, and (ii) factually supportable.

The unaudited pro forma condensed consolidated financial statements have been developed from financial information prepared in accordance with Accounting Principles Generally Accepted in the United States of America from the following sources:

Cohu’s unaudited consolidated balance sheet as of March 28, 2015 and unaudited statement of operations for the three months ended March 28, 2015 were derived from Cohu’s Quarterly Report on Form 10-Q for the interim period ended March 28, 2015 filed with the SEC on May 4, 2015.

Cohu’s audited consolidated statement of operations for the years ended December 24, 2014, December 28, 2013 and December 29, 2012 were derived from Cohu’s Annual Report on Form 10-K for the year ended December 27, 2014 filed with the SEC on February 24, 2015.
