### Footnotes:

(1) Pursuant to the Agreement and Plan of Merger ("Merger Agreement"), dated as of November 10, 2025, by and among TreeHouse Foods, Inc. ("TreeHouse"), Industrial F&B Investments II, Inc. ("Parent"), and Industrial F&B Investments III, Inc. ("Merger Sub"), Merger Sub merged with and into TreeHouse, with TreeHouse surviving the merger as a wholly owned subsidiary of Parent (the "Merger"). At the effective time of the Merger (the "Effective Time"), each share of TreeHouse's common stock, par value $0.01 per share, that was issued and outstanding immediately prior to the Effective Time was automatically canceled and converted into the right to receive (i) $22.50 in cash, less applicable taxes and withholding and (ii) one contractual contingent value right, which represents the right to receive a portion of the net proceeds, if any, resulting from certain litigation relating to part of TreeHouse's coffee business (clauses (i) and (ii) collectively, the "Merger Consideration").

(2) Reflects vested restricted stock units ("RSUs") further described in footnote three below.

(3) Each RSU represents a contingent right to receive one share of common stock of TreeHouse. Pursuant to the Merger Agreement, each RSU that was outstanding as of immediately prior to the Effective Time became fully vested and was automatically canceled and converted into the right to receive the Merger Consideration, less applicable taxes and withholding.

(4) Pursuant to the Merger Agreement, each performance share unit ("PSU") with respect to TreeHouse common stock subject to performance-based vesting conditions  that was outstanding as of immediately prior to the Effective Time became vested in the number of shares of TreeHouse common stock assuming that 130% of target level of performance had been achieved, and each such PSU was automatically canceled and converted into the right to receive the Merger Consideration, less applicable taxes and withholding, and any unvested portion was automatically canceled for no consideration.
