MICHAEL VIGNONE
Partner
Michael (“Mike”) Vignone advises private equity sponsors, strategic acquirers, investors, founders, established companies, emerging growth businesses, and management teams on sophisticated mergers and acquisitions, private equity investments, venture capital transactions, and other transformative corporate matters. He leads high-value, complex domestic and cross-border transactions involving innovative deal structures, representing clients in matters ranging from less than $1 million to more than $5 billion.
Mike represents clients across a broad range of industries, including business and professional services, consumer products, financial services, healthcare, and technology, among others. His practice includes acquisitions, divestitures, leveraged buyouts, growth equity and venture capital investments, minority and strategic investments, recapitalizations, and other strategic transactions. He also advises institutional investors, portfolio companies, entrepreneurs, and executive and management teams through every phase of a transaction.
A hands-on deal strategist, Mike regularly counsels clients on transactions involving complex structuring and financing arrangements, management rollovers, earnouts, carve-outs, and multijurisdictional acquisitions and divestitures. He works closely with clients to identify critical business and legal issues early, develop practical solutions, allocate risk effectively, and coordinate diligence, documentation, financing, execution, and post-closing planning. Known for his responsiveness, practical judgment, and commercial perspective, Mike guides transactions efficiently from strategy through closing.
In addition to his transactional practice, Mike advises companies at every stage of growth on entity formation, early-stage planning, venture financings, corporate governance, and general corporate matters. He often serves as an ongoing outside corporate adviser, helping clients address day-to-day business issues while positioning them for future growth, investment, or exit opportunities.
Before joining CROKE FAIRCHILD DUARTE & BERES LLC, Mike practiced at Goodwin Procter LLP, where he advised public and private companies, private equity sponsors, startups, and portfolio companies on mergers and acquisitions, leveraged buyouts, growth equity investments, and other strategic transactions. He began his legal career in the Chicago office of Sidley Austin LLP, focusing on mergers and acquisitions, private equity and venture capital matters, and general corporate counseling.
