In commenting on Main Street'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 was highlighted by a return on equity of 14.9% and includes 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. Our strong performance included continued positive results from our lower middle market and private loan investment strategies and significant contributions from our asset management business. 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've seen our pipeline of investment opportunities in both our lower middle market and private loan investment strategies continue to grow over the last month. This attractive investment pipeline, together with our conservative liquidity position and capital structure, provides us a continued favorable outlook for the second quarter."

Mr. Hyzak continued, "Our distributable net investment income in the first quarter exceeded the monthly dividends paid to our shareholders by 59% and the total dividends paid to our shareholders by 26%. This strong performance allowed us to deliver significant value to our shareholders, while still conservatively retaining a meaningful portion of our income and growing our net asset value per share. In addition, our strong first quarter results and favorable outlook for the second quarter resulted in the declaration of an increase to our monthly dividends for the third quarter of 2023 and a $0.225 per share supplemental dividend to be paid in June 2023. This June 2023 supplemental dividend represents our largest and seventh consecutive quarterly supplemental dividend and results in a 25% increase in the total dividends paid in the second quarter when compared to prior year."

First Quarter 2023 Operating Results

The following table provides a summary of our operating results for the first quarter of 2023:

	Three Months Ended March 31,
	2023	2022	Change ($)	Change (%)
Interest income	$ 93,392	$ 59,441	$ 33,951	57 %
Dividend income	24,222	16,622	7,600	46 %
Fee income	2,640	3,332	(692)	(21) %
Total investment income	$ 120,254	$ 79,395	$ 40,859	51 %

Net investment income	$ 80,967	$ 52,212	$ 28,755	55 %
Net investment income per share	$ 1.02	$ 0.73	$ 0.29	40 %

Distributable net investment income⁽¹⁾	$ 85,443	$ 54,654	$ 30,789	56 %
Distributable net investment income per share⁽¹⁾	$ 1.07	$ 0.76	$ 0.31	41 %

Net increase in net assets resulting from operations	$ 79,592	$ 65,203	$ 14,389	22 %
Net increase in net assets resulting from operations per share	$ 1.00	$ 0.91	$ 0.09	10 %

The $40.9 million increase in total investment income in the first quarter of 2023 from the comparable period of the prior year was principally attributable to (i) a $34.0 million increase in interest income, primarily due to higher average levels of investment portfolio debt investments, an increase in interest rates on floating rate investment portfolio debt investments primarily resulting from increases in benchmark index rates and an increase in interest rate spreads on new investments over the last year and (ii) a $7.6 million increase in dividend income, primarily due to an increase in dividend income from the External Investment Manager (as defined below) and increased dividends received from our LMM portfolio companies. These increases were partially offset by a $0.7 million decrease in fee income. The $40.9 million increase in total investment income in the first quarter of 2023 includes the impact of an increase of $8.1 million in certain income considered less consistent or non-recurring, including a $7.4 million increase of such dividend income as referenced above and a $0.7 million increase in income from accelerated prepayment, repricing and other activity related to portfolio debt investments, in both cases when compared to the same period in 2022.

Total cash expenses⁽³⁾ increased 40.7%, or $10.1 million, to $34.8 million in the first quarter of 2023 from $24.7 million for the same period in 2022. This increase in total cash expenses was principally attributable to (i) a $8.3 million increase in interest expense, (ii) a $3.1 million increase in cash compensation expenses⁽³⁾and (iii) a $0.9 million increase in general and administrative expense, partially offset by a $2.2 million increase in expenses allocated to the External Investment Manager. The increase in interest expense is primarily related to (i) an increased weighted average interest rate on our debt obligations resulting from the addition of the special purpose vehicle revolving credit facility (the "SPV Facility" and, together with the Corporate Facility, the "Credit Facilities") and the December 2025 Notes at higher contractual interest rates and an increased average interest rate on our Corporate Facility due to increases in benchmark index rates and (ii) increased average outstanding borrowings to fund our investment activity and support the growth of our investment portfolio. The increase in cash compensation expenses⁽³⁾is primarily related to (i) increased incentive compensation accruals, (ii) increased base compensation rates and (iii) increased headcount to support our growing investment portfolio and asset management activities.

Non-cash compensation expenses⁽³⁾ increased $2.1 million in the first quarter of 2023 from the comparable period of the prior year, resulting from a $1.3 million increase in share-based compensation and a $0.8 million increase in deferred compensation expense.

Our Operating Expenses to Assets Ratio (which includes non-cash compensation expenses⁽³⁾) was 1.3% for the first quarter of 2023, on an annualized basis, as compared to 1.1% for the same period in 2022.

The $28.8 million increase in net investment income and the $30.8 million increase in distributable net investment income⁽¹⁾ in the first quarter of 2023 from the comparable period of the prior year were both 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 first quarter of 2023 increased by $0.29 per share and $0.31 per share, respectively, compared to the first quarter of 2022, to $1.02 per share and $1.07 per share, respectively. These increases include the impact of an 10.9% increase in the average shares outstanding compared to the first quarter of 2022 primarily due to shares issued over the last twelve months (i) through our public offering in August 2022 and through our at-the-market ("ATM") program, (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 first quarter of 2023 include a $0.09 per share increase in investment income and non-cash compensation expense considered less consistent or non-recurring in nature compared to the first quarter of 2022, as discussed above.

The $79.6 million net increase in net assets resulting from operations in the first quarter of 2023 represents a $14.4 million increase from the first quarter of 2022. This increase was primarily the result of (i) a $20.4 million increase in net unrealized appreciation from portfolio investments (including the impact of accounting reversals relating to realized gains/income (losses)) and (ii) a $28.8 million increase in net investment income as discussed above, partially offset by (i) a $31.7 million change in net realized gain (loss) from investments resulting from a net realized loss of $28.4 million in the first quarter of 2023 compared to a net realized gain of $3.3 million in the first quarter of 2022 and (ii) a $3.0 million increase in income tax provision. The $28.4 million net realized loss from investments for the first quarter of 2023 was primarily the result of (i) a $29.5 million net realized loss from the full exit of one LMM debt investment and (ii) a $3.6 million net realized loss from the restructure of one LMM investment, partially offset by (i) a $3.2 million realized gain from the full exit of one middle market investment, (ii) a $0.9 million net realized gain from the full exit of one private loan investment and (iii) a $0.6 million net realized gain on an other portfolio investment.

The following table provides a summary of the total net unrealized appreciation of $35.1 million for the first quarter of 2023:

	Three Months Ended March 31, 2023
	LMM (a)	Private Loan	Middle Market	Other		Total
			(dollars in millions)
Accounting reversals of net unrealized (appreciation) depreciation recognized in prior periods due to net realized (gains / income) losses recognized during the current period	$ 32.9	$ 0.1	$ (3.2)	$ (0.7)		$ 29.1
Net unrealized appreciation (depreciation) relating to portfolio investments	11.2	(7.5)	(8.9)	11.2	(b)	$ 6.0
Total net unrealized appreciation (depreciation) relating to portfolio investments	$ 44.1	$ (7.4)	$ (12.1)	$ 10.5		$ 35.1

(a)	LMM includes unrealized appreciation on 29 LMM portfolio investments and unrealized depreciation on 23 LMM portfolio investments.
(b)	Other includes (i) $9.7 million of unrealized appreciation relating to the External Investment Manager, (ii) $0.4 million of unrealized appreciation relating to Main Street's deferred compensation plan assets and (iii) $1.1 million of net unrealized appreciation relating to the other portfolio.

Liquidity and Capital Resources

As of March 31, 2023, we had aggregate liquidity of $710.8 million, including (i) $39.8 million in cash and cash equivalents and (ii) $671.0 million of unused capacity under our Credit Facilities, which we maintain to support our investment and operating activities.

Several details regarding our capital structure as of March 31, 2023 are as follows:

Our Corporate Facility included $980.0 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.
$394.0 million in outstanding borrowings under our Corporate Facility, with an interest rate of 6.6% based on SOFR effective for the contractual reset date of April 1, 2023.

$170.0 million in outstanding borrowings under our SPV Facility, with an interest rate of 7.3% based on SOFR effective for the contractual reset date of April 1, 2023.
$334.0 million of outstanding Small Business Investment Company ("SBIC") debentures through our wholly owned SBIC subsidiaries. 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 2024, 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.

Investment Portfolio Information as of March 31, 2023⁽⁴⁾

The following table provides a summary of the investments in our LMM portfolio, private loan portfolio and middle market portfolio as of March 31, 2023:

	As of March 31, 2023
	LMM (a)	Private Loan	Middle Market
		(dollars in millions)
Number of portfolio companies	79	86	30
Fair value	$ 2,112.6	$ 1,491.4	$ 306.2
Cost	$ 1,727.9	$ 1,527.6	$ 391.0
Debt investments as a % of portfolio (at cost)	72.9 %	97.1 %	93.6 %
Equity investments as a % of portfolio (at cost)	27.1 %	2.9 %	6.4 %
% of debt investments at cost secured by first priority lien	99.2 %	99.5 %	99.3 %
Weighted-average annual effective yield (b)	12.6 %	12.4 %	11.8 %
Average EBITDA (c)	$ 8.3	$ 38.1	$ 65.4

(a)	We had equity ownership in all of our LMM portfolio companies, and our average fully diluted equity ownership in those portfolio companies was 41%.
(b)	The weighted-average annual effective yields were computed using the effective interest rates for all debt investments at cost, including amortization of deferred debt origination fees and accretion of original issue discount but excluding fees payable upon repayment of the debt instruments and any debt investments on non-accrual status.
(c)	The average EBITDA is calculated using a simple average for the LMM portfolio and a weighted-average for the private loan and middle market portfolios. These calculations exclude certain portfolio companies, including four LMM portfolio companies and two private loan portfolio companies, as EBITDA is not a meaningful valuation metric for our investments in these portfolio companies, and those portfolio companies whose primary purpose is to own real estate.

The fair value of our LMM portfolio company equity investments was 191% 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 2.9 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 2.6 to 1.0, respectively.^{(4) (5)}

As of March 31, 2023, our investment portfolio also included:

Other portfolio investments in 14 companies, collectively totaling $116.1 million in fair value and $119.7 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 $132.7 million and a cost basis of $29.5 million, which comprised 3.2% and 0.8% of our investment portfolio at fair value and cost, respectively.

As of March 31, 2023, we had 13 investments on non-accrual status, which comprised 0.6% of the total investment portfolio at fair value and 3.2% at cost, and our total portfolio investments at fair value were 110% 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 first quarter of 2023, the External Investment Manager earned $5.5 million of management fee income, an increase of $0.1 million from the first quarter of 2022, and incentive fees of $3.3 million, an increase of $3.2 million from the first quarter of 2022. In addition, we allocated $5.0 million of total expenses to the External Investment Manager, an increase of $2.2 million from the first quarter of 2022. The increase in management fee income was attributable 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 clients. The increase in expenses allocated to the External Investment Manager was primarily related to increased overall operating costs at Main Street, an increase in assets under management and the positive operating results from the assets managed for 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 $8.1 million, representing an increase of $3.0 million from the first quarter of 2022. The External Investment Manager ended the first quarter of 2023 with total assets under management of $1.4 billion.

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

(3) 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.

(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.
