(1)Represents the Sales Agents’ commission with respect to the shares of common stock being sold in this offering. There is no guarantee that there will be any additional sales of our common stock pursuant to the Prospectus.
(2)The percentage reflects estimated offering expenses for this offering of approximately $2,500,000, of which we have incurred $1,900,000 as of August 5, 2025, and assumes that we sell all $1.0 billion of shares of common stock available under the equity distribution agreements with the Sales Agents.
(3)The expenses of administering our dividend reinvestment plan (“DRIP”) are included in operating expenses. The DRIP does not allow shareholders to sell shares through the DRIP. If a shareholder wishes to sell shares they would be required to select a broker of their choice and pay any fees or other costs associated with the sale.
(4)Operating expenses in this table represent the estimated annual operating expenses of CSWC and its consolidated subsidiaries based on actual operating expenses for the quarter ended June 30, 2025. We do not have an investment adviser and are internally managed by our executive officers under the supervision of our board of directors. As a result, we do not pay investment advisory fees, but instead we pay the operating costs associated with employing investment management professionals including, without limitation, compensation expenses related to salaries, discretionary bonuses and restricted stock grants.
(5)Interest payments on borrowed funds represents (a) our estimated annual interest payments based on actual interest rate terms under our credit facilities, with available commitments of $510 million under the Company's senior secured revolving credit facility (the “Corporate Credit Facility”) and available commitments of $200 million under the Company's special purpose vehicle financing credit facility (the “SPV Credit Facility”), and our anticipated drawdowns from our credit facilities, (b) our actual interest rate terms under the SBA-guaranteed debentures issued by Capital Southwest SBIC I, LP (the "SBA Debentures") and our anticipated drawdowns of the SBA Debentures, and (c) our estimated annual interest payments, based on actual interest rate terms, on the 3.375% notes due 2026 (the “October 2026 Notes”), the 7.75% notes due 2028 (the “August 2028 Notes”), and the 5.125% convertible notes due 2029 (the "2029 Convertible Notes"). As of June 30, 2025, we had 200.0 million outstanding under our Corporate Credit Facility, $112.0 million outstanding under our SPV Credit Facility, $175.0 million outstanding under the SBA Debentures, $150.0 million in aggregate principal of the October 2026 Notes outstanding, $71.9 million in aggregate principal of the August 2028 Notes outstanding, and $230.0 million in aggregate principal of the 2029 Convertible Notes outstanding. Any future issuances of debt securities will be made at the discretion of management and our board of directors after evaluating the investment opportunities and economic situation of the Company and the market as a whole.
Example
The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed we would have no additional leverage and that our annual operating expenses would remain at the levels set forth in the table above. These amounts assume (1) a 1.50% sales load (Sales Agents discounts and commissions) and (2) offering expenses totaling 0.25%.

(1)NAV per share is determined as of the last day in the relevant quarter and therefore may not reflect the NAV per share on the date of the high and low sales prices. The NAVs shown are based on outstanding shares at the end of each period.
(2)Calculated as the respective high or low share price divided by NAV and subtracting 1.
On August 5, 2025, there were approximately 290 holders of record of our common stock, which did not include shareholders for whom shares are held in “nominee” or “street name.” On August 5, 2025, the closing price of our common stock on the Nasdaq Global Select Market was $22.62 per share.
Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. The possibility that our shares of common stock will trade at a discount from NAV per share or at premiums that are unsustainable over the long term are separate and distinct from the risk that our NAV per share will decrease. It is not possible to predict whether our common stock will trade at, above, or below NAV per share.
