WE NEED YOUR VOTE

Dear Stockholder:

We recently sent to you proxy materials regarding the upcoming Special Meeting of Stockholders (the “Meeting”) of Kayne Anderson Midstream/Energy Fund, Inc. (“KMF” or the “Fund”) scheduled to be held on October 16, 2015. Our records indicate that we have not received your proxy voting instructions for the Meeting. Please take a moment now to cast your proxy vote so that your shares may be represented. Another copy of your proxy ballot has been enclosed. Your vote is critical to the outcome of this Meeting.

Q. What am I being asked to vote on for this proxy?

A. Stockholders of KMF are being asked to consider and vote to approve a new investment management agreement (the “New KMF Agreement”) with KA Fund Advisors, LLC (the “Adviser”) and to approve any adjournments of the Meeting if there are insufficient votes at the time of the Meeting to constitute a quorum or to approve the New KMF Agreement.

Q. Are there meaningful differences between the current KMF investment management agreement (the “Current Agreement”) and the New KMF Agreement?

A. No. The proposed New KMF Agreement is substantially identical to the Current Agreement, except for the commencement and renewal dates. The amount of the management fee paid to the Adviser by the Fund under its Current Agreement will not change under the New Agreement. The Fund does not expect approval of the applicable New Agreement to negatively impact the level, nature or quality of services provided to the Fund or its stockholders by the Adviser.

Q. Where can I get a copy of the proxy statement?

A. The proxy statement is available on our website at this address:
