In the first quarter of fiscal 2025, the Company adopted the Twin Disc, Incorporated Amended and Restated 2021 Omnibus Incentive Plan (the “Omnibus Plan”), which was subsequently approved by the Company’s shareholders.  The Omnibus Plan amended and restated the Twin Disc, Incorporated 2021 Long-Term Incentive Plan (the “2021 LTI Plan”), and effectively replaced the Twin Disc, Incorporated 2020 Stock Incentive Plan for Non-Employee Directors (the “2020 Directors' Plan”).  Benefits under the Omnibus Plan may be granted, awarded or paid in any one or a combination of stock options, stock appreciation rights, restricted stock awards, restricted stock units, cash-settled restricted stock units, performance stock awards, performance stock unit awards, performance unit awards, and dividend equivalent awards.  The Omnibus Plan is designed to benefit key employees (including officers) of the Company and its subsidiaries, as well as non-employee directors and consultants of the Company.

There is reserved for issuance under the Plan an aggregate of 1,636.6 shares of the Company’s common stock, which consists of the previously-approved 715.0 shares of common stock reserved for issuance under the 2021 LTI Plan prior to its amendment and restatement to become the Omnibus Plan; 521.6 shares of common stock that remained available for issuance under the 2020 Directors' Plan; and 400.0 newly authorized shares of common stock. Shares issued under the Omnibus Plan may be authorized and unissued shares or shares reacquired by the Company in the open market or a combination of both. The aggregate amount is subject to proportionate adjustments for stock dividends, stock splits and similar changes.
