On April 16, 2025, the Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of Uniti Group Inc. (the “Company”) approved new form grant agreements (the “New Grant Agreements”) for time-based restricted shares (“RSAs”) and performance-based restricted stock unit awards (“PBRSUs”), pursuant to which awards may be granted to eligible employees of the Company and its subsidiaries under the Uniti Group 2015 Equity Incentive Plan (the “Plan”). In addition, the Committee approved the amendment and restatement of all existing grant agreements under the Plan pursuant to which awards remain outstanding to reflect the terms of and conditions of the New Grant Agreements, except for those certain grant agreements dated as of May 16, 2024, covering the special grant of awards of RSAs and PBRSUs (the “Special Awards”) granted in connection with the Agreement and Plan of Merger dated as of May 3, 2024 by and between the Company and Windstream Holdings II, LLC, a Delaware limited liability company (the transactions contemplated by such agreement, collectively, the “Merger”). The grant agreements underlying the Special Awards will be amended and restated to reflect the terms of and conditions of the New Grant Agreements following closing of the Merger. The amendments to the existing grant agreements primarily update the terms regarding the vesting of equity awards upon retirement, death, disability and in connection with a change in control in order to align them with the New Grant Agreements. The Committee also approved an amendment to that certain Performance-Based Restricted Stock Unit Agreement dated as of February 23, 2022 by and between the Company and Ronald Mudry, in order to extend the performance period for the awards granted thereunder from February 23, 2025 to February 23, 2028.
