As part of a thorough review of Board refreshment best practices and policies that began over two years ago, Crown Castle’s Board has unanimously approved an amendment to the Company’s Corporate Governance Guidelines to institute a mandatory Board retirement policy, pursuant to which the Board will not nominate any non-employee director who has reached 72 years of age. Under a transition plan approved by the Board in connection with the retirement policy, Robert E. Garrison II, Edward “Chap” Hutcheson, Jr. and Robert F. McKenzie will not be renominated for re-election at the Company’s 2021 Annual Meeting of Shareholders. In addition, Lee W. Hogan and J. Landis “Lanny” Martin will not be renominated for re-election at the Company’s 2022 Annual Meeting of Shareholders, at which time the Board will select a new independent Board Chair.
