Fourth Quarter Fiscal Year 2019 Operating Results

For the quarter ended March 31, 2019, Capital Southwest reported total investment income of $14.3 million, compared to $13.9 million in the prior quarter. The increase in total investment income was attributable to an increase in average debt investments outstanding.

For the quarter ended March 31, 2019, interest expense remained flat at $3.3 million as compared to the prior quarter.

The Company’s NAV per share at March 31, 2019 was $18.62, as compared to $18.43 at December 31, 2018. The increase in NAV per share from the prior quarter is due primarily to net unrealized appreciation on the investment portfolio.

Fiscal Year 2019 Operating Results

For the year ended March 31, 2019, Capital Southwest reported total investment income of $51.9 million, compared to $35.1 million in the prior year. The increase in investment income was attributable primarily to an increase in average debt investments outstanding.

For the year ended March 31, 2019, total operating expenses (excluding interest expense) were $14.9 million, compared to $13.8 million in the prior year.  The increase in operating expenses was primarily due to an increase in cash and stock-based compensation due to additional headcount.

For the year ended March 31, 2019, there was interest expense of $12.2 million, compared to $4.9 million in the prior year. The increase in interest expense during the year was due to increased average debt outstanding on our senior secured credit facility (the "Credit Facility"), as well as an increase in the average 5.95% Notes due 2022 (the "December 2022 Notes") outstanding.

For the year ended March 31, 2019, total pre-tax net investment income was $24.8 million, compared to $16.4 million in the prior year.

For the year ended March 31, 2019, there was tax expense of $1.0 million recorded, compared to $0.2 million in the prior year. The increase in tax expense versus the prior year was due primarily to an increase in excise tax.

The Company’s NAV per share at March 31, 2019 was $18.62, as compared to $19.08 at March 31, 2018.  The decrease in NAV per share from the prior year was primarily due to $0.90 per share in supplemental dividends paid during the year, partially offset by $0.53 per share in net realized and unrealized appreciation on the investment portfolio.

Liquidity and Capital Resources

At March 31, 2019, Capital Southwest had approximately $9.9 million in unrestricted cash and money market balances, $141 million of total debt outstanding on the Credit Facility and $75.1 million, net of unamortized debt issuance costs, of the December 2022 Notes outstanding.

On December 21, 2018, the Company entered into the Amended and Restated Senior Secured Revolving Credit Agreement (the "Credit Agreement"), and a related Amended and Restated Guarantee, Pledge and Security Agreement, to amend and restate the Credit Facility. The Credit Agreement (1) increased the total commitments by $60 million from $210 million to an aggregate total of $270 million, provided by a diversified group of nine lenders, (2) increased the Credit Facility's accordion feature to $350 million under the Credit Facility from new and existing lenders on the same terms and conditions as the existing commitments, (3) reduced the interest rate on borrowings from LIBOR plus 3.00% to LIBOR plus 2.50%, subject to certain conditions as outlined in the Credit Agreement, (4) reduced the minimum asset coverage with respect to senior securities representing indebtedness from 200% to 150% after the date on which such minimum asset coverage is permitted to be reduced by the Company under applicable law, and (5) extended the Credit Facility's revolving period from November 16, 2020 to December 21, 2022 and the final maturity from November 16, 2021 to December 21, 2023.

On May 23, 2019, the Company entered into an Incremental Assumption Agreement, which increased the total commitments under the Credit Facility by $25 million. The increase was executed under the accordion feature of the Credit Facility and increased total commitments from $270 million to $295 million.

On June 11, 2018, the Company entered into an "At-The-Market" ("ATM") debt distribution agreement, pursuant to which it may offer for sale, from time to time, up to $50 million in aggregate principal amount of the December 2022 Notes through B. Riley FBR, Inc., acting as its sales agent. Sales of the December 2022 Notes may be made in negotiated transactions or transactions that are deemed to be "at the market offerings" as defined in Rule 415 under the Securities Act of 1933, as amended, including sales made directly on The Nasdaq Global Select Market, or similar securities exchanges or sales made through a market maker other than on an exchange at prices related to prevailing market prices or at negotiated prices.

During the year ended March 31, 2019, the Company sold a total of 785,447 of the December 2022 Notes under the ATM debt distribution agreement, generating approximately $19.9 million in gross proceeds at an effective

yield of 5.86%. At this time, the Company does not intend to issue additional December 2022 Notes under this ATM debt distribution agreement.

On October 4, 2018, the Company issued an aggregate of 700,000 shares of the Company's common stock at a net price of $18.90 per share. The total net proceeds of the offerings, before expenses, was approximately $13.2 million. The shares were sold at a 1.9% discount to the prior day closing price and above then current NAV of $18.87.

On March 4, 2019, the Company entered into separate equity distribution agreements with certain sales agents through which it may offer and sell, from time to time, shares of its common stock having an aggregate offering price of up to $50,000,000 (the "Equity ATM Program"). During the year ended March 31, 2019, the Company sold 263,656 shares of its common stock under the Equity ATM Program at a weighted-average price of $21.47 per share, raising $5.7 million of gross proceeds. Net proceeds were $5.5 million after commissions to the sales agents on shares sold.

Additionally, I-45 SLF has total commitments outstanding of $165 million from a group of four bank lenders in its Deutsche Bank led credit facility, which is scheduled to mature in July 2022. As of March 31, 2019, I-45 SLF had $160 million in borrowings outstanding under its credit facility.

Share Repurchase Program

On January 25, 2016, Capital Southwest announced that its Board of Directors (the "Board") authorized the repurchase of up to $10 million of its common stock at prices below the Company’s NAV per share as reported in its most recent financial statements. The Board authorized the share repurchase program because it believes that the Company’s common stock may be undervalued from time to time due to market volatility.

During the year ended March 31, 2019, the Company repurchased 10,452 shares of common stock at an average price of $17.72 per share, including commissions paid. Cumulative to date, the Company has repurchased a total of 46,363 shares at an average price of $16.67 per share, including commissions paid. The Company currently has approximately $9.2 million available for additional repurchases under the program.

Declared Dividend of $0.49 Per Share for Quarter Ended June 30, 2019

On May 30, 2019, the Board declared a total dividend of $0.49 per share for the quarter ended June 30, 2019, comprised of a regular dividend of $0.39 per share and a supplemental dividend of $0.10 per share.

The Company's dividend will be payable as follows:

June 30, 2019 Dividend

Amount Per Share: $0.49

Ex-Dividend Date: June 13, 2019

Record Date: June 14, 2019

Payment Date: June 28, 2019

When declaring dividends, the Board reviews estimates of taxable income available for distribution, which may differ from net investment income under generally accepted accounting principles. The final determination of taxable income for each year, as well as the tax attributes for dividends in such year, will be made after the close of the tax year. 

Capital Southwest maintains a dividend reinvestment plan ("DRIP") that provides for the reinvestment of dividends on behalf of its registered stockholders who hold their shares with Capital Southwest’s transfer agent and registrar, American Stock Transfer and Trust Company.  Under the DRIP, if the Company declares a dividend, registered stockholders who have opted into the DRIP by the dividend record date will have their dividend automatically reinvested into additional shares of Capital Southwest common stock.

The 2019 Annual Meeting of Shareholders of Capital Southwest Corporation will be held at the Hilton Dallas Lincoln Centre, 5410 LBJ Freeway, Dallas, Texas 75240 in the Madison Conference Room on Wednesday, July 31, 2019, at 9:00 a.m. (Central Time) for shareholders of record as of the close of business on June 3, 2019.
