On March 1, 2022, Marianne M. Keler advised the Board of Trustees of CubeSmart of her intention to not stand for re-election to the Board at CubeSmart's 2022 Annual Meeting of Shareholders and her term will therefore end at the conclusion of the 2022 Annual Meeting. Ms. Keler joined the Board in 2007 and her retirement comes after 15 years of distinguished service to CubeSmart, including as Non-Executive Chair of the Board since May 2018. Ms. Keler confirmed to the Board that her determination to not stand for re-election is not the result of any disagreement with CubeSmart relating to its operations, policies or practices.

The Board has determined that, effective at the conclusion of the 2022 Annual Meeting, Deborah R. Salzberg, who has been a Trustee since May 2013, will become Non-Executive Chair of the Board. The Board intends to nominate Jair K. Lynch, age 50, to the Board for election by the shareholders at the 2022 Annual Meeting to fill the vacancy that will arise upon Ms. Keler's retirement.
