Subsequent Events	20. Subsequent Events Icahn Enterprises Distribution On February 23, 2022, the Board of Directors of the general partner of Icahn Enterprises declared a quarterly distribution in the amount of $2.00 per depositary unit, which will be paid on or about April 27, 2022 to depositary unitholders of record at the close of business on March 18, 2022.

Icahn Enterprises will make a cash payment in lieu of issuing fractional depositary units to any unitholders electing to receive (or who are deemed to have elected to receive) depositary units.
