The foregoing Compensation Committee Report shall not be deemed under the Securities Act or the Exchange Act to be (i) "soliciting material" or "filed" or (ii) incorporated by reference by any general statement into any filing made by us with the SEC, except to the extent that we specifically incorporate such report by reference.

### PAY-RELATED VOTE

#### PROPOSAL 3 ON EXECUTIVE COMPENSATION
<div align='center'>PROPOSAL 3: NON-BINDING VOTE ON EXECUTIVE COMPENSATION</div>

We are requesting that our shareholders approve, on an advisory (non-binding) basis, the compensation of our NEOs as disclosed in this Proxy Statement, by voting on the following resolution:

"RESOLVED, that our shareholders approve, on an advisory basis, the compensation of our NEOs as described in this Proxy Statement for the 2025 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the Summary Compensation

| NATIONAL STORAGE AFFILIATES 2025 PROXY STATEMENT |     | 45 |

Table and the other related tables and narrative disclosure."

Because your vote is advisory, it will not be binding upon us or our Board. However, the CNCG Committee, which is responsible for designing and administering our executive compensation programs, values your opinion and has and will continue to take into account the outcome of the vote when considering future executive compensation arrangements.

If a quorum is present, the affirmative vote of a majority of the votes cast on the proposal at the Annual Meeting is required to approve, on an advisory basis, the compensation of our NEOs. Proxies solicited by our Board will be voted FOR this proposal, unless otherwise instructed. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote, although they will be considered present for the purposes of determining the presence of a quorum.

Our Board recommends a vote FOR approval of the compensation of our NEOs as described in the Compensation Discussion and Analysis, the compensation tables and other narrative disclosure in this Proxy Statement
