Main Street Announces Preliminary Estimate of Fourth Quarter 2022 Operating Results

Announces Federal Tax Treatment of 2022 Dividends

Announces Fourth Quarter and Full Year 2022 Earnings Release and Conference Call Schedule

HOUSTON, Jan. 17, 2023 /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 2022, the federal tax treatment of its 2022 dividends and its fourth quarter and full year 2022 earnings release and conference call schedule.

In commenting on the Company's operating results for the fourth quarter of 2022, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are very pleased with our fourth quarter results, which closed another record year for Main Street across several key performance indicators with significant positive momentum for 2023. These results demonstrate the continued and sustainable strength of our overall platform, the benefits of our differentiated and diversified investment strategies and the underlying quality of our portfolio companies. Our unique lower middle market investment strategy continues to provide benefits with a robust fourth quarter concluding another strong year of investment activity with originations totaling $373 million for the year. During the year, we executed 5 new platform investments and follow-on investments in 13 of our existing lower middle market portfolio companies to support their acquisition and organic growth strategies and other investor value creation events. Our private loan investment strategy also had another successful year resulting in growth in our private loan portfolio of $335 million and continued growth of assets under management in our asset management business. Together, the investment activity in our lower middle market and private loan investment strategies resulted in a net increase in our total investment portfolio of $515 million on a cost basis during the year, to a record total investment portfolio of $3.8 billion on a cost basis at year end."

Mr. Hyzak continued, "The benefits of the positive performance from our existing investment portfolio and our strong investment activity, combined with the benefits of our strong capital structure, efficient operating model and accretive asset management business, resulted in another quarterly and annual record for distributable net investment income per share. As a result, our quarterly distributable net investment income exceeded $1 per share for the first time and exceeded the monthly dividends paid to our shareholders by over 56% for the quarter and over 33% for the year. Our strong overall operating performance resulted in a quarterly return on equity on an annualized basis of over 20%. This continued positive momentum across our platform has delivered significant increased value to our shareholders as evidenced by two sequential quarterly increases in our regular monthly dividends in the fourth quarter of 2022 and the first quarter of 2023. In addition, based upon these record fourth quarter results, we expect another meaningful supplemental dividend to be paid in the first quarter of 2023, continuing the additional value we've been providing to our shareholders through the payment of $0.35 per share in supplemental dividends during 2022."

Main Street's preliminary estimate of fourth quarter 2022 net investment income ("NII") is $0.97 to $0.99 per share. Main Street's preliminary estimate of fourth quarter 2022 distributable net investment income ("DNII"), which is NII before non-cash compensation expenses, is $1.02 to $1.04 per share.⁽¹⁾

Main Street's preliminary estimate of net asset value ("NAV") per share as of December 31, 2022 is $26.83 to $26.89, representing an increase of $0.89 to $0.95 per share, or 3.4% to 3.7%, from the NAV per share of $25.94 as of September 30, 2022, with this increase after the impact of the supplemental dividend paid in December 2022 of $0.10 per share. The estimated increase in NAV per share is primarily due to the net fair value increases from the unrealized appreciation in the fair value of our lower middle market ("LMM") investments, our wholly owned asset management business and our private loan portfolio investments, partially offset by realized losses on our private loan portfolio investments and unrealized depreciation and realized losses on our middle market portfolio investments; the accretive impact from equity issuances during the quarter; and the record estimated NII, which exceeded the regular monthly dividends of $0.66 per share and supplemental dividend of $0.10 per share paid in the fourth quarter.

The Company's fourth quarter 2022 operating activities include the following investment activity in its LMM, private loan and middle market investment strategies:

• $151.6 million in total LMM portfolio investments, which after aggregate repayments of debt principal and return of invested equity capital from several LMM portfolio investments resulted in a net increase of $126.6 million in the cost basis of our LMM investment portfolio;
• $86.4 million in total private loan investments, which after aggregate repayments and sales resulted in a net decrease of $26.1 million in the cost basis of our private loan investment portfolio; and
• a net decrease of $19.4 million in the cost basis of our middle market investment portfolio.
