On August 19, 2024, the SEC instituted settled cease-and-desist proceedings against Icahn Enterprises L.P., stating: "IEP, a public company, failed to disclose that Carl C. Icahn, its founder, controlling shareholder, and Chairman of the Board of Directors of its general partner, pledged IEP securities as collateral to secure personal margin loans under agreements with various lenders in its Forms 10-K for at least the fiscal years ended December 31, 2018 through December 31, 2020, as required by Item 403(b) of Regulation S-K. IEP’s failures to disclose deprived existing and prospective IEP investors of information required to be disclosed. As a result, IEP violated Section 13(a) of the Exchange Act and Rule 13a-1 thereunder."

On August 19, 2024, the SEC "announced charges against Carl C. Icahn and his publicly traded company, Icahn Enterprises L.P. (IEP), for failing to disclose information relating to Icahn’s pledges of IEP securities as collateral to secure personal margin loans worth billions of dollars under agreements with various lenders. IEP and Icahn agreed to pay $1.5 million and $500,000 in civil penalties, respectively, to settle the SEC’s charges."
