Former Mayer Brown M&A lawyer Frederick "Fritz" Lark last week moved his energy deal-making practice to McDermott Will & Emery, citing a desire to take advantage of the firm's recent investments in a "one-stop" energy practice.

Lark started as a partner in McDermott's transactions practice last Friday, just days before the largest federal cash infusion into the U.S. clean energy market in history via the Inflation Reduction Act. Signed into law Tuesday, attorneys say the IRA legislation will stimulate energy M&A due to the tax credits and investments in renewable energy infrastructure provided by the bill.

The latest addition to the firm's transactions practice in New York bolsters McDermott's initiative to build out the corporate bench strength necessary to aid clients in navigating the shifting energy landscape to renewables and the "historic" impact on the U.S. energy market of the IRA.
