In commenting on the Company's operating results for the fourth quarter and full year 2022, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are very pleased with our fourth quarter, which closed another record year for Main Street across several key performance indicators with significant positive momentum for 2023. Our results include new quarterly records for net investment income per share and distributable net investment income per share, significantly exceeding our new records achieved in the prior quarter. 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. The positive results include contributions from our lower middle market and private loan investment strategies and our asset management business, providing us confidence about the recurring nature of these positive results in the future. As a result of our strong performance, our quarterly distributable net investment income per share exceeded $1 per share for the first time and exceeded our regular monthly dividends by over 56% for the quarter. We continue to be pleased with the performance of our lower middle market portfolio companies, which resulted in another quarter of meaningful fair value appreciation in the equity investments in this portfolio, and we are excited about the $151.6 million in new and follow-on investments we made in lower middle market portfolio companies during the quarter. Our positive fourth quarter results and our favorable outlook for the first quarter resulted in the declaration of another supplemental dividend of $0.175 per share to be paid in March, representing our largest and sixth consecutive quarterly supplemental dividend."

Mr. Hyzak continued, "We are also pleased with the strong results for the year which also included record net investment income per share and distributable net investment income per share and allowed us to end the year at a record net asset value per share. Our total investment portfolio grew by over half a billion dollars in 2022, or over 15%. Additionally, with our new lending relationships that we added in 2022 and the continued support from our long-term lender relationships, we enter the new year with strong liquidity and a conservative leverage profile. We continue to be very encouraged with the continued favorable performance of our diversified lower middle market and private loan investment strategies and remain confident that these strategies, together with the benefits of our asset management business and our cost efficient operating structure, will allow us to continue to deliver superior results for our shareholders."

Fourth Quarter 2022 Operating Results

The following table provides a summary of our operating results for the fourth quarter of 2022:

The $31.7 million increase in total investment income in the fourth quarter of 2022 from the comparable period of the prior year was principally attributable to (i) a $32.5 million increase in interest income, primarily due to higher average levels of investment portfolio debt investments, and an increase in interest rates on floating rate investment portfolio debt investments primarily resulting from increases in benchmark index rates during the year and also due to an increase in interest rate spreads on the new investments over the last year and (ii) a $0.6 million increase in dividend income, primarily due to an increase in dividend income from the External Investment Manager (as defined below). These increases were partially offset by a $1.4 million decrease in fee income. The $31.7 million increase in total investment income in the fourth quarter of 2022 includes comparable amounts of investment income considered less consistent or non-recurring in nature to such items included in total investment income in 2021.

Total cash expenses⁽²⁾ increased 23.0%, or $6.3 million, to $33.9 million in the fourth quarter of 2022 from $27.5 million for the same period in 2021. This increase in total cash expenses was principally attributable to (i) a $7.1 million increase in interest expense and (ii) a $1.5 million increase in general and administrative expense, partially offset by (i) a $1.6 million decrease in cash compensation expenses⁽²⁾ and (ii) a $0.8 million increase in expenses allocated to the External Investment Manager. The increase in interest expense is primarily related to (i) increased average outstanding borrowings to fund our investment activity and support the growth of our investment portfolio over the last year and (ii) the increased average interest rate on our Credit Facilities resulting from an increase in the interest rate on our Corporate Facility due to increases in benchmark index rates and the addition of the SPV Facility to our capital structure at a higher floating interest rate than our Corporate Facility. The decrease in cash compensation expenses⁽²⁾ is primarily related to decreased incentive compensation accruals, partially offset by increases in base compensation rates and headcount to support our growing investment portfolio and asset management activities.

Non-cash compensation expenses⁽²⁾ increased $0.7 million in the fourth quarter of 2022 from the comparable period of the prior year, principally attributable to a $0.7 million increase in share-based compensation, resulting from an increase in incentive based grants related to incentive compensation awards for 2021.

Our Operating Expenses to Assets Ratio (which includes non-cash compensation expenses⁽²⁾) was 1.4% for the fourth quarter of 2022, on an annualized basis, as compared to 1.7% for the same period in 2021, and 1.4% for the full year 2022, as compared to 1.5% for the full year 2021.

The $24.7 million increase in net investment income and the $25.4 million increase in distributable net investment income⁽¹⁾ in the fourth quarter of 2022 from the comparable period of the prior year were principally attributable to the increase in total investment income, partially offset by increased expenses, each as discussed above.

Net investment income and distributable net investment income⁽¹⁾ on a per share basis for the fourth quarter of 2022 each increased by $0.25 per share, compared to the fourth quarter of 2021, to $0.98 per share and $1.03 per share, respectively. These increases include the impact of an 11.0% increase in the average shares outstanding compared to the fourth quarter of 2021 primarily due to (i) shares issued through our public offering in August 2022 and through our at-the-market ("ATM") program over the last twelve months, (ii) shares issued through our equity incentive plans and (iii) shares issued through our dividend reinvestment plan. Net investment income and distributable net investment income⁽¹⁾ on a per share basis in the fourth quarter of 2022 each include comparable amounts of investment income and non-cash compensation expense considered less consistent or non-recurring in nature to such items included in net investment income and distributable net investment income in the fourth quarter of 2021.

The $106.3 million net increase in net assets resulting from operations in the fourth quarter of 2022 represents a $12.0 million increase from the fourth quarter of 2021. This increase was primarily the result of (i) a $26.2 million increase in net unrealized appreciation from portfolio investments (including the impact of accounting reversals relating to realized gains/income (losses)) resulting from a net unrealized appreciation of $44.7 million in the fourth quarter of 2022 compared to a net unrealized appreciation of $18.6 million in the fourth quarter of 2021, (ii) a $24.7 million increase in net investment income as discussed above and (iii) a $4.3 million decrease in income tax provision, partially offset by a $43.3 million decrease in net realized gain from investments resulting from a net realized loss of $8.5 million in the fourth quarter of 2022 compared to a net realized gain of $34.8 million in the fourth quarter of 2021. The $8.5 million net realized loss from investments for the fourth quarter of 2022 was primarily the result of (i) an $8.4 million net realized loss from the restructure of two private loan investments and (ii) a $1.2 million realized loss from the full exit of one middle market investment, partially offset by a $1.2 million realized gain on the partial exit of a LMM investment.

The following table provides a summary of the total net unrealized appreciation of $44.7 million for the fourth quarter of 2022:

Liquidity and Capital Resources

As of December 31, 2022, we had aggregate liquidity of $617.1 million, including (i) $49.1 million in cash and cash equivalents and (ii) $568.0 million of unused capacity under our Credit Facilities, which we maintain to support our investment and operating activities.

Subsequent to December 31, 2022, we further diversified our capital structure and expanded our liquidity by amending our Corporate Facility to add an additional lender and expand the total commitments by $60.0 million to $980.0 million in total commitments and by issuing an additional $50.0 million of the December 2025 Notes bearing interest at 7.53%.

Several details regarding our capital structure as of December 31, 2022 are as follows:

• Our Corporate Facility included $920.0 million in total commitments from a diversified group of 18 participating lenders, plus an accordion feature that allows us to request an increase in the total commitments under the facility to up to $1.4 billion.
• $407.0 million in outstanding borrowings under our Corporate Facility, with an interest rate of 6.1% based on SOFR effective for the contractual reset date of January 1, 2023.

These debentures, which are guaranteed by the U.S. Small Business Administration, had a weighted-average annual fixed interest rate of 2.9% and mature ten years from original issuance. The first maturity related to our existing SBIC debentures occurs in the first quarter of 2023, and the weighted-average remaining duration was 5.1 years.
• $500.0 million of notes outstanding that bear interest at a rate of 3.00% per year (the "July 2026 Notes"). The July 2026 Notes mature on July 14, 2026 and may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions.
• $450.0 million of notes outstanding that bear interest at a rate of 5.20% per year (the "May 2024 Notes"). The May 2024 Notes mature on May 1, 2024 and may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions.
• $100.0 million of the December 2025 Notes outstanding that bear interest at a rate of 7.84% per year. The December 2025 Notes mature on December 23, 2025 and may be redeemed in whole or in part at any time at our option subject to certain make-whole provisions.

Investment Portfolio Information as of December 31, 2022⁽⁴⁾

The following table provides a summary of the investments in our LMM portfolio, private loan portfolio and middle market portfolio as of December 31, 2022:

The fair value of our LMM portfolio company equity investments was 190% of the cost of such equity investments, and our LMM portfolio companies had a median net senior debt (senior interest-bearing debt through our debt position less cash and cash equivalents) to EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) ratio of 3.1 to 1.0 and a median total EBITDA to senior interest expense ratio of 2.6 to 1.0. Including all debt that is junior in priority to our debt position, these median ratios were 3.1 to 1.0 and 2.5 to 1.0, respectively.^{(4) (5)}

As of December 31, 2022, our investment portfolio also included:

• Other portfolio investments in 14 companies, collectively totaling $116.3 million in fair value and $120.4 million in cost basis, which comprised 2.8% and 3.2% of our investment portfolio at fair value and cost, respectively; and
• Our investment in the External Investment Manager, with a fair value of $122.9 million and a cost basis of $29.5 million, which comprised 3.0% and 0.8% of our investment portfolio at fair value and cost, respectively.

As of December 31, 2022, we had 12 investments on non-accrual status, which comprised 0.6% of the total investment portfolio at fair value and 3.7% at cost, and our total portfolio investments at fair value were 109% of the related cost basis.

External Investment Manager

MSC Adviser I, LLC is a wholly owned portfolio company and registered investment adviser that provides investment management services to external parties (the "External Investment Manager"). We share employees with the External Investment Manager and allocate costs related to such shared employees and other operating expenses to the External Investment Manager. The total contribution of the External Investment Manager to our net investment income consists of the combination of the expenses we allocate to the External Investment Manager and the dividend income we earn from the External Investment Manager. During the fourth quarter of 2022, the External Investment Manager earned $5.4 million of management fee income, an increase of $0.5 million from the fourth quarter of 2021, and incentive fees of $2.5 million, an increase of $1.9 million from the fourth quarter of 2021. In addition, we allocated $3.4 million of total expenses to the External Investment Manager, an increase of $0.8 million from the fourth quarter of 2021. The increases in management fee income and expenses allocated were primarily related to an increase in assets under management. The increase in incentive fees was attributable to the favorable performance and improved operating results from the assets managed for the clients. The combination of the dividend income we earned from the External Investment Manager and expenses we allocated to it resulted in a total contribution to our net investment income of $7.0 million, representing an increase of $2.1 million from the fourth quarter of 2021. The External Investment Manager ended the fourth quarter of 2022 with total assets under management of $1.4 billion.

Endnotes

(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⁽²⁾. Main Street believes presenting distributable net investment income and the related per share amount is useful and appropriate supplemental disclosure for analyzing its financial performance since non-cash compensation expenses⁽²⁾ do 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 or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. A reconciliation of net investment income in accordance with U.S. GAAP to distributable net investment income is detailed in the financial tables included with this press release.

(2) Non-cash compensation expenses consist of (i) share-based compensation and (ii) deferred compensation expense or benefit, both of which are non-cash in nature. Share-based compensation does not require settlement in cash. Deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement. The appreciation (depreciation) in the fair value of deferred compensation plan assets is reflected in Main Street's Consolidated Statements of Operations as unrealized appreciation (depreciation) and an increase (decrease) in compensation expenses, respectively. Cash compensation expenses are total compensation expenses as determined in accordance with U.S. GAAP, less non-cash compensation expenses. Total cash expenses are total expenses, as determined in accordance with U.S. GAAP, excluding non-cash compensation expenses. Main Street believes presenting cash compensation expenses, non-cash compensation expenses and total cash expenses is useful and appropriate supplemental disclosure for analyzing its financial performance since non-cash compensation expenses do not result in a net cash impact to Main Street upon settlement. However, cash compensation expenses, non-cash compensation expenses and total cash expenses are non-U.S. GAAP measures and should not be considered as a replacement for compensation expenses, total expenses or other earnings measures presented in accordance with U.S. GAAP and should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. A reconciliation of compensation expenses and total expenses in accordance with U.S. GAAP to cash compensation expenses, non-cash compensation expenses and total cash expenses is detailed in the financial tables included with this press release.

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

(4) Portfolio company financial information has not been independently verified by Main Street.

(5) These credit statistics exclude portfolio companies on non-accrual or for which EBITDA is not a meaningful metric.
