January 26, 2026
FOR IMMEDIATE RELEASE
NEWPORT BEACH—January 26, 2026—O’Melveny announced today that seasoned corporate dealmaker and adviser Matt O’Loughlin has joined the firm’s Newport Beach office as a partner in the Mergers & Acquisitions Practice Group, strengthening O’Melveny’s West Coast M&A, public company, and transactional capabilities and expanding its nationwide roster of corporate lawyers.
O’Loughlin brings more than 20 years of experience handling complex public and private M&A deals, advising on private equity and venture capital transactions, and counseling public company boards of directors on financing and governance issues, SEC reporting, and transactional strategy. He guides successful entrepreneurs and closely held businesses through their liquidity events. O’Loughlin also has deep industry knowledge in a wide range of areas—including life sciences, tech, venture capital, financial services, asset management, consumer products, and food and agriculture—having led buy-side and sell-side mergers and acquisitions, joint ventures, and venture and growth financings, as well as securities offerings in those sectors.
O’Loughlin joins O’Melveny from the Los Angeles office of Proskauer Rose, where he was a partner in that firm’s Mergers and Acquisitions Group.
“Matt is a highly accomplished and trusted M&A adviser with a superb track record across a broad array of sophisticated transactions,” said O’Melveny chair Bradley J. Butwin. “His experience in life sciences, tech, and other dynamic sectors will help us continue advancing our strategic objectives both in Southern California and across our platform. We are delighted to welcome him to our firm.”
“I have long admired O’Melveny for its reputation as a premier firm, its high-profile work across transactional areas, its incredible depth and breadth in South California, and its renowned collaborative culture,” O’Loughlin said. “The firm’s multidisciplinary teams and outstanding bench of talent in areas crucial to my clients make it an ideal fit. I’m thrilled to be joining and look forward to contributing to the firm’s continued corporate expansion.”
O’Loughlin’s arrival bolsters O’Melveny’s growing Corporate Department and accelerates the firm’s strategic growth. He is the 43rd lateral partner to join O’Melveny since 2023. That includes 26 corporate partners spanning offices from New York, Los Angeles, Century City, Newport Beach, Dallas, and Houston to London and Singapore.
O’Loughlin earned his Bachelor of Arts (Hons) and Bachelor of Laws (LL.B.) from the University of Otago, in New Zealand, and his LL.M. from the University of California, Berkeley School of Law.
