Divestment to an affiliate of The Carlyle Group in exchange for a minority equity stake in newly-capitalized venture allows MACOM to participate in NewCo's potential long-term value creation

LOWELL, Mass.--(BUSINESS WIRE)-- MACOM Technology Solutions Holdings, Inc. (NASDAQ: MTSI) (MACOM), a leading supplier of high-performance analog RF, microwave, millimeterwave and lightwave semiconductors, today announced that it has entered into an agreement to sell the Compute business it acquired in its AppliedMicro acquisition earlier this year to Project Denver Holdings LLC (NewCo), a new company backed by The Carlyle Group. Under the terms of the sale, MACOM will be issued a minority equity ownership interest in NewCo.

"After a thorough review process, we are very excited about the sale of the Compute business and the opportunity it provides for both the employees of that business and our shareholders," said John Croteau, MACOM's President and Chief Executive Officer. "The Carlyle Group is one of the world's largest and most successful global investment firms, with over $170 billion in assets under management. I believe NewCo's exceptional leadership team and Carlyle's backing combines the necessary elements to make the business a long-term success, and through a minority equity ownership MACOM is positioned to participate in the company's long-term value creation."

Patrick McCarter, Co-head of Carlyle's global Technology, Media & Telecom team, said, "We are excited to partner with MACOM on this investment and look forward to working with the team to create value."

Equity for Carlyle's investment came from Carlyle Partners VI, a $13 billion U.S. buyout fund. The divestment transaction became effective concurrently with the signing of the definitive agreement, with the exception of the transfer of certain assets and entities in jurisdictions outside of the United States, which will be transferred upon receipt of applicable foreign approvals.

Evercore acted as exclusive financial advisor and Ropes & Gray LLP served as legal counsel to MACOM. Carlyle was advised by Alston & Bird LLP.
