 Meeting.  You may also vote electronically at the Annual Meeting if you hold your Common Shares in street name by following the instructions provided by your intermediary. To vote electronically at the Annual Meeting, you will need the 16-digit control number included in your Notice, on your proxy card or on the instructions that accompany your proxy materials. |

Even if you plan to attend the Annual Meeting via the live webcast, your plans may change, so we recommend you vote in advance of the meeting.

#### How to Revoke a Proxy
Any common shareholder of record submitting a proxy retains the power to revoke such proxy at any time prior to its exercise at the Annual Meeting by (i) delivering at or prior to the Annual Meeting a written notice of revocation to our corporate secretary at National Storage Affiliates Trust, 8400 East Prentice Avenue, 9th Floor, Greenwood Village, CO 80111, (ii) submitting a later-dated proxy or (iii) voting electronically at the Annual Meeting. Attending the Annual Meeting via the live webcast will not automatically revoke your previously submitted proxy unless you vote electronically at the Annual Meeting. If your shares are held in "street name" through an intermediary and you desire to change your vote, you should contact your intermediary for instructions on how to do so.

#### ANNUAL REPORT
This Proxy Statement is accompanied by our annual report to shareholders (our "Annual Report to Shareholders"), which includes our 2024 Form 10-K.

### OTHER MATTERS
Our Board knows of no other business that may be properly presented at the Annual Meeting. The proxies for the Annual Meeting confer discretionary authority on the persons named therein as proxy holders to vote on any matter proposed by shareholders for consideration at the Annual Meeting. As to any other business which may properly come before the Annual Meeting, the persons named as proxy holders on your proxy card will vote the Common Shares represented by properly submitted proxies in their discretion.

### DELIVERY OF MATERIALS
In accordance with SEC rules, instead of mailing a printed copy of our proxy materials to our shareholders, we are, except as described below, furnishing proxy materials, including this Proxy Statement and our 2024 Annual Report to Shareholders, by providing access to these documents on the Internet. Accordingly, on or about March 28, 2025, the Notice will be sent to our beneficial owners of shares (i.e., those who hold in street name through an intermediary). The Notice provides instructions for accessing our proxy materials on the Internet and instructions for
