Today is the day on which Caesars Entertainment (NASDAQ: CZR) investors are voting on the proposed $17.6 billion takeover floated by Tilman Fertitta’s Fertitta Entertainment Inc. (FEI), but prior to the meeting, a party believed to be an investor in the casino giant issued a demand letter requesting access to some financial records.

In a Form 8-K filing with the Securities and Exchange Commission (SEC), Caesars acknowledged that on Tuesday, Sept. 15 it received a demand letter “from a purported stockholder of the company.” Citing Section 220 of the General Corporation Law of the State of Delaware, the potentially disgruntled investor claims that in an August proxy filing , Caesars didn’t disclose that its legal counsel Latham & Watkins LLP also has a relationship with entities tied to FEI.

Put simply, Caesars voluntarily enhanced the proxy filing to avoid delays to the takeover and potentially costly legal proceedings.

While Caesars did bolster its proxy filing, it’s not admitting any wrongdoing nor is the casino operator confirming that the shareholder who issued the demand letter is in the right.

Prior to the Harrah’s operator acknowledging receipt of the demand letter, it was fair to say that the most interesting nugget in the August proxy filing was confirmation that the company had held takeover talks with Carl Icahn and that the discussions dated back to 2025.

The corporate raider offered $34 a share to acquire the Horseshoe operator, but that bid was rejected due to debt-related complexities and lack of support from the Carano family, which controls a significant portion of Caesars equity.

It was revealed last week that two Icahn Enterprises (NYSE: IEP) employees who also served on the Caesars board resigned from those director roles .

Caesars investors are likely to approve the Fertitta offer because the board has recommended they do so and because aside from the Icahn proposal, there’s no known competing bid.
