**EXPLANATORY NOTE** 

On March 8, 2023, ClearBridge Energy Midstream Opportunity Fund Inc. (the "Fund") filed its Definitive Proxy Statement on Schedule 14A and the related Proxy Card (the "Proxy Statement") with the Securities and Exchange Commission for the Fund's 2023 Annual Meeting of Stockholders to be held at 280 Park Avenue, New York, New York 10017, on April 14, 2023 at 10:30 a.m. New York Time (the "Annual Meeting").

This supplement to the Proxy Statement (the "Supplement") is being filed to supplement and clarify the "Disclosure of Fees Paid to Independent Registered Public Accounting Firm—Tax Fees" section on page 27 of the Proxy Statement.

Other than replacing the "Disclosure of Fees Paid to Independent Registered Public Accounting Firm—Tax Fees" section in its entirety, no other information in the Proxy Statement has been revised, supplemented, updated or amended and the Proxy Statement continues to be in full force and effect as originally filed and the Fund continues to seek the vote of its stockholders for all proposals to be voted on at the Annual Meeting. **The Supplement should be read together with the Proxy Statement.**

If you have already returned your **<u>WHITE</u>** proxy card or voting instruction form or provided voting instructions, you do not need to take any action unless you wish to change your vote.
