Commencing December 20, 2023, a video message with the following script is expected to be used by Gladstone Capital Corporation to solicit votes in connection with its special meeting of stockholders.

Hello. I’m David Gladstone, Chairman & CEO of Gladstone Capital Corporation and on behalf of the entire Gladstone Group, we’d like to thank you for being a loyal shareholder.

We have an upcoming shareholders’ meeting that we recently adjourned due to lack of shareholder participation and I’m reaching out today because your voice is important.

You really have three options in voting — you can vote FOR, of course, you can vote AGAINST, either of those are fine, and you can vote to ABSTAIN if you want to and that counts for us as well.

By voting, you will remove yourself from all the additional solicitations that we pay for.

I’m really asking you today to please vote your shares.

Voting is quick and easy – you can mail your vote with the proxy card that you got, you can also vote online with your proxy card number by entering the control number. You can also vote by phone through a live representative. Just call 833-786-5515.

Now, once again, on behalf of all of us here at your company, thank you for being a loyal shareholder and I thank you if you’ll vote your shares. Thank you.
