Main Street Announces Preliminary Estimate of First Quarter 2023 Operating Results

Announces First Quarter 2023 Earnings Release and Conference Call Schedule

HOUSTON, April 18, 2023 /PRNewswire/ -- Main Street Capital Corporation (NYSE: MAIN) ("Main Street" or the "Company") is pleased to announce its preliminary operating results for the first quarter of 2023 and its first quarter 2023 earnings release and conference call schedule.

In commenting on the Company's operating results for the first quarter of 2023, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are very pleased with our performance in the first quarter, which resulted in new quarterly records for net investment income per share, distributable net investment income per share and net asset value per share for the third consecutive quarter and a return on equity of over 14%. Our performance included positive results from our lower middle market and private loan investment strategies and significant contributions from our asset management business, continuing our positive momentum from the last few quarters. 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 underlying quality of our portfolio companies. We are also pleased that we ended the first quarter with an attractive pipeline of investment opportunities in our lower middle market and private loan investment strategies, which we expect will be helpful as we work to maintain our positive momentum from the last few quarters."

Mr. Hyzak continued, "Our distributable net investment income in the first quarter exceeded the monthly dividends paid to our shareholders by over 55% and the total dividends paid to our shareholders by over 20%, allowing us to deliver significant value to our shareholders while still conservatively retaining a meaningful portion of our income. Our continued positive performance over the last few quarters has allowed us to deliver significantly increased value to our shareholders through the two sequential quarterly increases to our regular monthly dividends in the fourth quarter of 2022 and the first quarter of 2023 and the consistent payment of meaningful quarterly supplemental dividends. In addition, based on our strong first quarter results, we expect another meaningful supplemental dividend to be paid in the second quarter of 2023, which would represent our seventh consecutive quarterly supplemental dividend and would result in another quarter in which we provide significant additional value to our shareholders."

Preliminary Estimates of First Quarter 2023 Results

Main Street's preliminary estimates of first quarter 2023 net investment income ("NII") is $1.01 to $1.03 per share and distributable net investment income ("DNII"), which is NII before non-cash compensation expenses, is $1.06 to $1.08 per share.⁽¹⁾

Main Street's preliminary estimate of net asset value ("NAV") per share as of March 31, 2023 is $27.20 to $27.26, representing an increase of $0.34 to $0.40 per share, or 1.3% to 1.5%, from the NAV per share of $26.86 as of December 31, 2022, with this increase after the impact of the supplemental dividend paid in March 2023 of $0.175 per share. The estimated increase in NAV per share is primarily due to the record estimated NII, which exceeded the regular monthly dividends of $0.675 per share and supplemental dividend of $0.175 per share paid in the first quarter, the accretive impact from equity issuances during the quarter and the net fair value increase on the investment portfolio resulting from the net unrealized appreciation on our portfolio investments, partially offset by net realized losses on our portfolio investments and the tax provision resulting from the net realized and unrealized fair value changes on our investment portfolio.

As a result of Main Street's preliminary estimates of net investment income 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 for the first quarter of 2023 of 14% to 15%.⁽²⁾

Investment Portfolio Activity

The Company's first quarter 2023 operating activities include the following investment activity in our LMM, private loan and middle market investment strategies:

$58.7 million in total LMM portfolio investments, which after aggregate repayments of debt principal from several LMM portfolio investments and a decrease in cost basis due to the realized loss on a LMM portfolio investment resulted in a net increase of $7.6 million in the cost basis of our LMM investment portfolio;
$43.7 million in total private loan investments, which after aggregate repayments resulted in a net increase of $23.6 million in the cost basis of our private loan investment portfolio; and
a net decrease of $12.2 million in the cost basis of our middle market investment portfolio.

Although its management believes that the expectations reflected in those forward-looking statements are reasonable, Main Street can give no assurance that those expectations will prove to be correct. Those forward-looking statements are made based on various underlying assumptions and are subject to numerous uncertainties and risks, including, without limitation, such factors described under the captions "Cautionary Statement Concerning Forward-Looking Statements" and "Risk Factors" included in Main Street's filings with the Securities and Exchange Commission (the "SEC") (www.sec.gov).

As a result, actual results could differ materially from the current preliminary estimates based on adjustments made during Main Street's quarter-end closing and review procedures and third-party review, and Main Street's reported information in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 may differ from this information, and any such differences may be material.

End Notes

(1)	Distributable net investment income is net investment income as determined in accordance with U.S. Generally Accepted Accounting Principles, or U.S. GAAP, excluding the impact of non-cash compensation expenses, which includes both share-based compensation expenses and deferred compensation expense or benefit. Main Street believes presenting distributable net investment income per share is useful and appropriate supplemental disclosure for analyzing its financial performance, since share-based compensation does not require settlement in cash and deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement. However, distributable net investment income is a non-U.S. GAAP measure and should not be considered as a replacement for net investment income and other earnings measures presented in accordance with U.S. GAAP. Instead, distributable net investment income should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. In order to reconcile estimated distributable net investment income per share to estimated net investment income per share in accordance with U.S. GAAP for the first quarter of 2023, $0.05 to $0.06 per share of estimated non-cash compensation expenses are added back to calculate estimated distributable net investment income per share.

(2)	Return on equity equals the net increase in net assets resulting from operations divided by the average quarterly total net assets.

(3)	No information contained on our website or disclosed on the May 5, 2023 conference call, including the webcast and the archived versions, is incorporated by reference in this press release or any of our filings with the SEC, and you should not consider that information to be part of this press release or any other such filing.
