Global professional services firm Alvarez & Marsal’s (A&M) continued the expansion of its corporate transaction group (CTG) with the appointments of new managing directors, Joe Deegan and Lyna Sun.
Deegan brings over 30 years of experience advising controlling shareholders, company boards and senior executives, focusing on accelerating accretive growth through acquisitions, alliances, divestitures and joint ventures. He has worked on global projects in more than 60 countries, helping clients in consumer goods, healthcare and manufacturing achieve enterprise and stakeholder value throughout the M&A lifecycle with a focus on enterprise and operational transformation as well as employee engagement, productivity and performance. Deegan was previously a partner/principal at EY and served in client leadership roles within its transaction advisory services and people advisory services practices.
Sun brings over 20 years of experience leading complex buy- and sell-side transactions, spin-offs, IPO divestitures and joint ventures. Specializing in operational due diligence, synergy realization, culture, communications, organizational design and cross-border transaction execution, she has advised on deals ranging from $100 million to $50 billion across 125 countries and industries including life sciences, healthcare, energy, financial services and consumer and retail. Prior to A&M, Sun served as KPMG’s U.S. national practice leader for people strategy and HR transactions and held leadership roles at EY’s transaction advisory services and in-house M&A functions in healthcare and life sciences.
“The market’s quick and positive response to CTG’s offering reinforces the need for an integrated end-to-end M&A solution; A&M saw this gap for corporate clients and we built and continue to scale a solution,” Paul Aversano, managing director and global transaction advisory group practice leader, who oversees CTG, said. “In an increasingly complex corporate transactions marketplace, CTG already stands apart against its competitors, bringing unrivaled senior market talent like Joe and Lyna into its ranks and backed with the operational, industry and functional expertise within a globally integrated platform that A&M is known for.”
“As the market prepares for an expected 2025 deal-making surge, we anticipate an increasingly competitive M&A environment with mounting valuation and operational challenges facing corporates,” Preston Parker, managing director and U.S. practice leader of CTG, said. “Joe and Lyna’s joining deepens our talent bench and bolsters our ability to provide an alternative pathway for generating value and driving growth that traditional Big Four approaches can’t deliver and can’t duplicate. Their collective experience will augment our delivery of bespoke solutions required by corporates and strategics for a successful transaction outcome.”
“CTG’s ability to advise on wide ranging issues and its practitioners’ in-depth industry expertise serve as the engine powering the group’s holistic offering,” Deegan said. “Solving for corporates’ current and future M&A concerns requires the fact-based, innovative and hands-on approach that CTG delivers for clients.”
“The team’s collective cross-border M&A, diligence, carve-out, integration, transaction execution, operational turnaround and performance improvement expertise complements the firm’s integrated platform and bolsters its global network of transaction professionals,” Sun said.
