KM&T Investment Holdings, LLC ("KM&T Investment") is beneficially owned by Koch Minerals & Trading, LLC ("KM&T "), KM&T is beneficially owned by Koch Solutions, LLC ("Koch Solutions") and Koch Solutions is beneficially owned by Koch Industries, Inc. ("Koch Industries"), in each case by means of ownership of all voting equity instruments. Koch Industries, Koch Solutions and KM&T may be deemed to beneficially own the shares of Common Stock of Compass Minerals International, Inc. (the "Issuer") held by KM&T Investment by virtue of (i) Koch Industries' beneficial ownership of Koch Solutions, (ii) Koch Solutions' beneficial ownership of KM&T and (iii) KM&T's beneficial ownership of KM&T Investment.

Remarks:
Pursuant to the Stock Purchase Agreement, dated September 14, 2022, between the Issuer and KM&T, KM&T Investment has the right to designate two directors to the Issuer's board of directors and, therefore, KM&T Investment and Koch Industries may each be deemed a "director by deputization" of the Issuer.
