Your vote is important and still needed. Please vote your shares today. R44527-LTR Dear Fellow Shareholders: We have adjourned the voting, until September 1, 2026, on the proposal to increase the number of authorized shares to allow shareholders more time to submit their vote. Please help save the Company additional solicitation costs by voting your proxy today. The previously disseminated formal notice of the Annual Meeting and our proxy statement outline the proposals being considered for a shareholder vote. Of particular importance, you will be asked to vote upon a proposed amendment to our charter to increase the number of authorized shares from 75,000,000 to 135,000,000 shares. We believe that the additional authorized shares of common stock will allow us to continue our strong track re- cord of growing our asset base by pursuing attractive investment opportunities consistent with our investment strategy over the next 5 to 10 years. Since 2015, Capital Southwest has grown total balance sheet assets from approximately $290 million to ap- proximately $2.2 billion as of March 31, 2026. During the past 10 years of asset growth, Capital Southwest has raised approximately $929 million in gross equity proceeds at a weighted average premium of 130% to the prevailing net asset value per share. Although the Company has no specific plans at this time for the use of additional shares of common stock, having additional authorized shares of common stock available for issuance in the future would give the Com- pany greater capital markets flexibility. Your vote is very important to us, regardless of the number of shares you hold. It is extremely important we reach the required voting threshold to approve the charter amendment. We have hired Georgeson LLC, a proxy solici- tor who may contact you prior to the adjourned - meeting date to assist you in the voting process. You may also reach Georgeson by contacting them toll-free at: 877-576-4833 or outside the US and Canada call: 570-218-9186. Once your vote has been received, your account will be removed from solicitation efforts. On behalf of management and our Board of Directors, we thank you for your continued support of Capital Southwest Corporation. Sincerely, Michael Sarner President and Chief Executive Officer PROXY QUESTIONS?
