Notable Mentions

  • Law360, " No Sign Of A Summer M&A Slowdown In Sight" – Quoted in an article regarding the M&A climate in the summer of 2021. "We're in a sweet spot for M&A activity,” noting the continuing prevalence of representation and warranty insurance, pent-up demand from deal-hungry corporations, and the hefty pile of private equity dry powder as just a few of the factors driving this year's M&A boom. "There are five or so ingredients right now that all add up to an extremely active M&A market," he said. "But if you change two or three of those ingredients — whether that's tax reform or increasing antitrust scrutiny under the Biden administration — that might no longer be the case."
  • Mergers and Acquisitions, " Aon-Willis Failed Merger Signals More Antitrust Scrutiny for Big Deals" – Quoted in an article regarding increased antitrust scrutiny on M&A transactions. “Recent developments shouldn’t be surprising as it relates to regulatory scrutiny of deals—particularly larger deals where there is perceived market concentration. Regulatory developments often follow a predictable path. An expectation arises, as it did after the election, then official pronouncements are made, as illustrated by the recent presidential order. Then specific actions manifest themselves, as has happened with some recent deals being questioned, with some being abandoned.”
