Acquisition Expected to Strengthen Cirrus Logic’s Leadership Position in Audio ICs and Software for Portable Audio Applications

AUSTIN, Texas & EDINGBURGH, Scotland-- April 29,2014 -- Cirrus Logic, Inc. (NASDAQ : CRUS) and Wolfson Microelectronics plc (LSE : WLF or WLF.L) today announced the terms of a recommended transaction under which Cirrus Logic would acquire Wolfson at a price of £2.35 per share in cash, implying an enterprise value of £278 million, or approximately $467 million.

“The Board of Wolfson believes that this is an attractive offer for Wolfson shareholders,” said Michael Ruettger, Chairman of the Board of Wolfson Microelectronics. “We believe this reflects the hard work that Mike Hickey and his team have put into building Wolfson as a leader in the supply of high performance Audio Hubs and MEMS microphones to the consumer electronics market. Together with Cirrus Logic, we believe this will create a powerful platform for future growth, above and beyond our standalone potential.”
