 see “THE MERGER – No Dissenters’ Rights in the Merger” on page 60. Voting Agreement (page 72) On the date the Merger Agreement was executed, each member of the Board of Directors of First Savings and certain executive officers of First Savings entered into a voting agreement with First Merchants to cause all First Savings common stock owned and controlled by each of them of record or beneficially on such date to be voted in favor of the Merger Proposal. See “THE MERGER AGREEMENT – Voting Agreement” on page 72. As of October 15, 2025, the First Savings shareholders who are parties to the voting agreement had the power to vote, or caused to be voted, an aggregate of 1,009,491 shares of First Savings common stock outstanding, representing 14.5% of the outstanding shares on that date.
