On December 29, 2023, National Storage Affiliates Trust (the “Company”) amended and restated the LTIP Unit Award Agreements for the Company’s executive officers with respect to awards granted pursuant to agreements dated (i) February 26, 2021 (the “2021 Agreements”), (ii) March 15, 2022 and August 26, 2022 (the “2022 Agreements”), and (iii) February 27, 2023 and June 5, 2023 (the “2023 Agreements,” and together with the 2021 Agreements and the 2022 Agreements, the “Executive Award Agreements”). The Executive Award Agreements contain, among other things, performance-based vesting for a portion of the awards under which vesting is based in part on the Company’s three-year total shareholder return (“TSR”), relative to the TSRs of its four stock exchange-listed company self storage peers (such group, the “Peer Group” and such performance-based component, the “Peer TSR Component”).

As a result of a merger between two members of the Peer Group in July 2023 (the “Merger”) , one member of the Peer Group was eliminated as a standalone company and therefore, since the closing of the Merger the Peer Group includes only three other stock exchange-listed self storage companies. Accordingly, as the measurement period of the Peer TSR Component is over a three-year period, and each Peer Group member must be part of the Peer Group for the entirety of the measurement period, the Company’s Compensation, Nominating and Corporate Governance Committee (the “CNCG Committee”) determined that it would be appropriate to amend certain aspects of the Executive Award Agreements in which the Company’s performance was compared to the Peer Group for purposes of determining the portions of the awards that vest.

With respect to the amendment and restatement of the 2022 Agreements and the 2023 Agreements (the “Amended and Restated 2022 and 2023 Agreements”), the CNCG Committee revised these agreements to, among other things: (i) account for one less member in the Peer Group as with the amendment and restatement of the 2021 Agreements; (ii) modify the potential award under each of the 2022 Agreements and 2023 Agreements to now compare the Company’s TSR to the cumulative three-year weighted average of the Peer Group’s TSR (“Peer Group Weighted Average TSR”) plus or minus a certain number of basis points (previously the Company’s three-year relative TSR was compared to the three-year relative TSR of the Peer Group, with payout determined by achieving either fourth place for the minimum award, 110% of the Peer Group’s average TSR for the target award, or first place for the maximum award); and (iii) modify the allocation of performance-based long term incentive performance units (“LTIPs”) such that 30% (previously 50%) of the potential award is based on the Peer TSR Component and 70% (previously 50%) of the potential award vests based on a comparison of the Company’s three-year TSR relative to the MSCI US REIT Index, which allocation percentages would be subject to a 10% decrease (in the case of the Peer TSR Component) and a 10% increase (in the case of the component based on the MSCI US REIT Index) if another peer is removed from the SS Peer Group. As a result of these modifications, the fair value of the awards (on an accounting basis) in the Executive Award Agreements as of the accounting modification date of such agreements has decreased as compared to the fair value of the awards prior to modification.
