Marinelli, to serve as a director of the Company, effective immediately. With Mr. Marinelli’s appointment, the USAC board size increases to seven members, five of which are Independent. Mr. Marinelli has also been appointed Chairman of a new board committee formed yesterday, the Finance Committee.

Mr. Marinelli is a seasoned financial executive and investment professional with more than 25 years of experience in capital markets, M&A, and strategic advisory roles, and has an early-career background in technology. He is the Founder and Principal of 1042 Capital Partners, where he manages public and private investments. Previously, he served as Group Head and Managing Director of U.S. Energy at BMO Capital Markets, and before that held senior roles in Deutsche Bank’s Global Banking–Natural Resources Group, the successor to Bankers Trust. Over his career, Mr. Marinelli has advised on more than $285 billion in M&A, public and private equity, and debt transactions. He holds an MBA from Rice University and a BS from Miami University.

Mr. Marinelli will serve until the Company’s next annual meeting of shareholders and until his successor is duly elected and qualified, or until his earlier death, resignation, or removal. There are no arrangements or understandings between Mr. Marinelli and any other person pursuant to which he was selected as a director, and there are no transactions involving Mr. Marinelli that are required to be disclosed under Item 404(a) of Regulation S-K.
