America's Top Mergers & Acquisition (M&A) Lawyers 2025

In the rarefied world of mega-mergers and acquisitions, a cadre of elite lawyers shepherd the biggest and most complex deals in America. They are the strategists and tacticians who advise CEOs, private equity firms and corporate boards on the transactions that reshape industries and change the business landscape. It’s a high pressure field with tight timelines and high-stakes negotiations. But with great risk comes great reward: M&A practices at the country’s largest firms earn billions of dollars a year.

This sort of ROI has made the field a financial foundation for Big Law, with strong markets and accessible capital fueling a relentless churn of multibillion dollar deals. But as businesses face macroeconomic, regulatory and geopolitical uncertainty, dealmakers have become more selective and chary. They are looking to their legal advisors not only to close business, but to help divine shifting markets and accurately assess risk versus opportunity.

Forbes’ inaugural list of America’s Top M&A Lawyers spotlights counselors with these transcendental abilities; they combine legal precision with business judgment, prescience with practicality, and exceptional capability during boom markets and bad. Forbes’ short list of the best in the field parlay years of industry expertise in deal structuring, acquisitions, dispositions, financing arrangements and activist takeover and defense—across all business sectors and all borders. They don’t just make deals, they are the architects of transactions whose strategic insight have made them indispensable.
