KOCH INDUSTRIES LLC is no longer subject to Section 16 filing requirements. Form 4 or Form 5 obligations may continue.
1. Effective on August 1, 2024, pursuant to an internal reorganization, Koch Industries, LLC (formerly known as Koch Industries, Inc.) ("KII") ceased to own equity interests, directly or indirectly, of KM&T Investment Holdings, LLC ("KM&T Investment"), and Koch, Inc. became the indirect ultimate parent company of both KM&T Investment and KII.

(the "Issuer") held by KM&T Investment, nor shall it be deemed a "director by deputization" of the Issuer because of KM&T Investment's designation of each of Vance Holtzman and Shane Wagnon to the Issuer's board of directors.
