Main Street Announces Preliminary Estimate of Fourth Quarter 2023 Operating Results

Announces Federal Tax Treatment of 2023 Dividends

Announces Fourth Quarter and Full Year 2023 Earnings Release and Conference Call Schedule

HOUSTON, Jan. 17, 2024 /PRNewswire/ -- Main Street Capital Corporation (NYSE: MAIN) ("Main Street" or the "Company") is pleased to announce its preliminary operating results for the fourth quarter of 2023, the federal tax treatment of its dividends paid in 2023 and its fourth quarter and full year 2023 earnings release and conference call schedule.

In commenting on the Company's operating results for the fourth quarter of 2023, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are extremely pleased with our performance in the fourth quarter, which closed another record year for Main Street across several key financial metrics. Our fourth quarter performance resulted in net investment income per share and distributable net investment income per share at levels near or above our quarterly records, a new record for net asset value per share for the sixth consecutive quarter and an estimated return on equity of over 22% for the fourth quarter. Our strong performance in the fourth quarter continued our positive performance in the first three quarters of 2023 and resulted in new annual records for net investment income per share and distributable net investment income per share and a return on equity of approximately 19% for the year. These results demonstrate the continued and sustainable strength of our overall platform, the benefits of our differentiated and diversified investment strategies, the unique contributions of our asset management business and the continued underlying strength and quality of our portfolio companies. We are further pleased to be able to generate these returns while intentionally maintaining a very conservative capital structure and liquidity position during 2023."

Mr. Hyzak continued, "The continued positive momentum across our platform in 2023 has allowed us to deliver significantly increased value to our shareholders, with a 25% increase in the total dividends paid to our shareholders in 2023. Despite this significant increase, our estimated distributable net investment income exceeded the monthly dividends paid to our shareholders by over 55% for both the fourth quarter and the year and the total dividends paid to our shareholders by over 13% for the fourth quarter and over 17% for the year. Based upon the continued strength of our performance in the fourth quarter, we expect another meaningful supplemental dividend to be paid in the first quarter of 2024. This would represent our tenth consecutive quarterly supplemental dividend, to go with the seven increases to our regular monthly dividends in the same time period, allowing us to deliver significant value to our shareholders, while continuing to maintain a conservative dividend policy and retain a meaningful portion of our income for the future benefit of our stakeholders."

Preliminary Estimates of Fourth Quarter 2023 Results

Main Street's preliminary estimate of fourth quarter 2023 net investment income ("NII") is $1.06 to $1.08 per share and distributable net investment income ("DNII") is $1.11 to $1.13 per share.⁽¹⁾

Main Street's preliminary estimate of net asset value ("NAV") per share as of December 31, 2023 is $29.17 to $29.23, representing an increase of $0.84 to $0.90 per share, or 3.0% to 3.2%, from the NAV per share of $28.33 as of September 30, 2023, with this increase after the impact of the supplemental dividend paid in December 2023 of $0.275 per share. The estimated increase in NAV per share is primarily due to the net fair value increase on the investment portfolio resulting from the net unrealized appreciation and the net realized losses on portfolio investments, including an increase in the fair value of the wholly-owned asset manager, the accretive impact of equity issuances during the quarter, the estimated record NII, which exceeded the regular monthly dividends of $0.705 per share and supplemental dividend of $0.275 per share paid in the fourth quarter, and a net tax benefit for the quarter.

As a result of Main Street's preliminary estimates of NII and net changes in the fair market value of its investment portfolio as noted above, Main Street estimates that it generated a quarterly annualized return on equity of 22% to 23% for the fourth quarter of 2023⁽²⁾ and approximately 19% for the full year.⁽²⁾

Investment Portfolio Activity

The Company's fourth quarter 2023 operating activities include the following investment activity in the lower middle market ("LMM"), private loan and middle market investment strategies:

• $92.3 million in total LMM portfolio investments, which after aggregate repayments of debt principal and return of invested equity capital from a LMM portfolio investment resulted in a net increase of $65.7 million in the cost basis of the LMM investment portfolio;
• $160.4 million in total private loan investments, which after aggregate repayments from several private loan portfolio investments and a decrease in cost basis due to the realized loss on a private loan portfolio investment resulted in a net decrease of $112.5 million in the cost basis of the private loan investment portfolio; and
• a net decrease of $50.3 million in the cost basis of the middle market investment portfolio.

Federal Tax Treatment of 2023 Dividends

Main Street has posted information regarding the U.S. federal income tax characteristics of its dividends paid in 2023 on its website under "2023 Form 1099 Information" (https://www.mainstcapital.com/investors/listed-securities-information/tax-information).⁽³⁾ Main Street paid dividends totaling $3.695 per share in 2023, with approximately 8% of such dividends taxed as qualified dividends and approximately 92% taxed as ordinary income. Qualified dividends paid to non-corporate taxpayers (including individuals) qualify for favorable tax treatment under the Internal Revenue Code ("IRC") and, for 2023, will generally be subject to a maximum 20% U.S. federal income tax rate (plus a 3.8% Medicare surtax, if applicable).
