Keith Cozza has resigned from the board of Caesars Entertainement. The CEO of Icahn Enterprises left abruptly after a Monday morning announcement with the Securities and Exchange Commission.

The July 27 announcement stated:

“On July 24, 2020, Keith Cozza informed the Executive Chairman of the Board of Directors (the “Board”) of Caesars Entertainment, Inc., a Delaware corporation (the “Company”), that he is resigning from the Board effective immediately. Mr. Cozza’s resignation was not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.”

Cozza was one of three representatives for Carl Icahn on Caesars’ board. The 83-year-old billionaire gained the largest stake of any shareholder in the company in early 2019, and was an important player in arranging the sale of the company to Eldorado. He remains the largest shareholder in the new combined company.
