Key Terms

net investment income, distributable net investment income, net asset value, non-accrual status, +4 more

8 terms

net investment income financial

"Main Street's preliminary estimate of fourth quarter 2025 net investment income ("NII") is $1.01..."

Net investment income is the money an investor or fund actually keeps from its investments after subtracting the costs of running those investments (like management fees, interest, and losses). Think of it as your paycheck from owning assets: gross returns minus the bills needed to earn them. Investors watch it because it shows how profitable the investment activities are, influences dividend payouts and cash available for growth, and helps compare true performance across funds or companies.

distributable net investment income financial

"distributable net investment income ("DNII")(1) is $1.07 to $1.11 per share..."

Distributable net investment income is the portion of a fund’s or investment vehicle’s earnings from interest, dividends and other investment returns, after operating costs and required adjustments, that is available to be paid out to shareholders. It matters to investors because it signals the likely size and sustainability of cash distributions or dividends—think of it as the household budget left over for paying regular allowances after bills are paid.

net asset value financial

"Main Street's preliminary estimate of net asset value ("NAV") per share as of December 31, 2025..."

Net asset value is the total value of an investment fund's assets minus any liabilities, divided by the number of shares or units outstanding. It represents the per-share worth of the fund, similar to how the value of a house is determined by its total worth after debts are subtracted. Investors use it to gauge the true value of their holdings and to compare different investment options.

non-accrual status financial

"investments on non-accrual status comprised 1.0% of the total investment portfolio..."

A loan or credit account is placed in non-accrual status when the lender stops recording expected interest income because the borrower is not making scheduled payments or repayment is doubtful. Think of it like a landlord who stops counting unpaid rent as future income once a tenant stops paying; it signals rising credit problems and potential losses. For investors, non-accrual levels indicate loan quality and can foreshadow write-downs, lower earnings, and increased risk to a lender’s balance sheet.

return on equity financial

"resulted in an estimated return on equity of over 17% for the quarter and for the full year."

Return on equity shows how effectively a company uses its shareholders' money to generate profit. It is calculated by dividing the company's net profit by its shareholders' equity, indicating how much profit is earned for each dollar invested by owners. Higher return on equity suggests the company is good at turning investments into earnings, which can be an important factor for investors assessing its profitability and efficiency.

qualified dividends financial

"approximately 8% of such dividends taxed as qualified dividends and approximately 92% taxed..."

Dividends that meet tax rules allowing them to be taxed at the lower long-term capital gains rates instead of higher ordinary income rates. For investors, that means more of the payment stays in your pocket; it influences which dividend-paying stocks you buy and how long you hold them, similar to getting a discount for meeting a store’s membership conditions.

ordinary income financial

"approximately 8% of such dividends taxed as qualified dividends and approximately 92% taxed as ordinary income."

Ordinary income is the money you earn regularly from jobs, business activities, or investments like interest and rental income. It’s important because it’s the main amount you report to the government for taxes and helps determine how much you owe. Think of it as your paycheck or steady earnings that come in regularly.

regulated investment company regulatory

"Non-U.S. resident and foreign corporation shareholders ("Non-U.S. Shareholders") in a Regulated Investment Company ("RIC"), such as Main Street..."

A regulated investment company is a type of pooled investment (like a mutual fund or ETF) that meets specific tax-law rules allowing it to pass most income, gains and losses directly to shareholders instead of being taxed at the company level. For investors this matters because it affects how distributions are taxed, how often income is paid, and the overall net return—think of it like a collective account that funnels earnings straight to owners rather than keeping profits inside a separate corporate layer.

Announces Federal Tax Treatment of 2025 Dividends

Announces Fourth Quarter and Full Year 2025 Earnings Release and Conference Call Schedule

HOUSTON, Jan. 15, 2026 /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 2025, the federal tax treatment of its dividends paid in 2025 and its fourth quarter and full year 2025 earnings release and conference call schedule.

In commenting on the Company's preliminary operating results for the fourth quarter of 2025, Dwayne L. Hyzak, Main Street's Chief Executive Officer, stated, "We are extremely pleased with our continued strong performance in the fourth quarter, which closed another great year for Main Street across our key financial metrics, including several new quarterly and annual records. Our preliminary operating results highlight that our fourth quarter performance resulted in another quarter of strong operating results, including favorable distributable net investment income per share and a new record for net asset value per share for the fourteenth consecutive quarter, primarily driven by a significant net fair value increase and including the benefits of material net realized gains in both our lower middle market and private loan investment portfolios. We also produced extremely strong fourth quarter investment activity in our unique lower middle market investment strategy, resulting in an annual record for gross investments of approximately $700 million in 2025. Our fourth quarter results continued our positive performance over the last few years and resulted in an estimated return on equity of over 17% for the quarter and for the full year. We look forward to sharing the full details of our fourth quarter and full year 2025 results in late February."

Preliminary Estimates of Fourth Quarter 2025 Results

Main Street's preliminary estimate of fourth quarter 2025 net investment income ("NII") is $1.01 to $1.05 per share, distributable net investment income ("DNII")⁽¹⁾ is $1.07 to $1.11 per share and DNII before taxes⁽²⁾ is $1.09 to $1.13 per share.

Main Street's preliminary estimate of net asset value ("NAV") per share as of December 31, 2025 is $33.29 to $33.37, representing an increase of $0.51 to $0.59 per share, or 1.5% to 1.8%, from the NAV per share of $32.78 as of September 30, 2025, with this increase after the impact of the supplemental dividend paid in December 2025 of $0.30 per share. The estimated NAV per share increase is primarily due to the net fair value increase of the investment portfolio and the accretive impact of equity issuances, partially offset by the net tax provision for the quarter. The net fair value increase of the existing investment portfolio is primarily the result of net fair value increases of the existing lower middle market ("LMM") and private loan investment portfolios, partially offset by net fair value decreases of the wholly-owned asset manager and the residual middle market investment portfolio.

As a result of Main Street's preliminary estimates of NII, the net changes in the fair value of the investment portfolio and the net tax provision as noted above, Main Street estimates that it generated a return on equity of over 17% for both the fourth quarter on an annualized basis and for the full year of 2025.⁽³⁾

Main Street preliminarily estimates that investments on non-accrual status comprised 1.0% of the total investment portfolio at fair value and 3.3% at cost as of December 31, 2025.

Investment Portfolio Activity

The Company's fourth quarter 2025 operating activities include the following investment activity in the LMM and private loan investment strategies:

• $300.0 million in total LMM portfolio investments, which after aggregate repayments and return of invested equity capital, including a decrease in cost basis associated with the exits of several LMM portfolio investments, resulted in a net increase of $253.1 million in the total cost basis of the LMM investment portfolio; and
• $231.4 million in total private loan portfolio investments, which after aggregate repayments, return of invested equity capital associated with the exit of two private loan portfolio investments and a decrease in cost basis due to a realized loss on a private loan portfolio investment resulted in a net increase of $108.8 million in the total cost basis of the private loan investment portfolio.

Federal Tax Treatment of 2025 Dividends

Main Street has posted information regarding the U.S. federal income tax characteristics of its dividends paid in 2025 on its website under "2025 Form 1099 Information" (https://www.mainstcapital.com/investors/listed-securities-information/tax-information).⁽⁴⁾ Main Street paid dividends totaling $4.23 per share in 2025, 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 2025, will generally be subject to a maximum 20% U.S. federal income tax rate (plus a 3.8% Medicare surtax, if applicable).

Federal Tax Treatment of 2025 Dividends – Non-U.S. Shareholders

Non-U.S. resident and foreign corporation shareholders ("Non-U.S. Shareholders") in a Regulated Investment Company ("RIC"), such as Main Street, are exempt from U.S. withholding tax on both "interest-related" dividends and short-term capital gains in accordance with the IRC Sections 871(k) and 881(e). In addition, Non-U.S. Shareholders in a RIC are also exempt from U.S. withholding tax on long-term capital gains. Main Street paid dividends totaling $4.23 per share in 2025, with approximately 47% of such dividends relating to "interest-related" dividends and short-term capital gains. See "Tax Treatment of 2025 Dividends to Non-U.S. Shareholders" posted on Main Street's website for more details (https://www.mainstcapital.com/investors/listed-securities-information/tax-information).⁽⁴⁾

To the extent Non-U.S. Shareholder taxes were withheld on dividends distributed, this information may be considered in connection with any claims for refund on taxes made with the U.S. Internal Revenue Service. Non-U.S. Shareholders should contact their tax advisor with any questions regarding this information.

Endnotes

(1)  DNII is NII 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 DNII per share is useful and appropriate supplemental disclosure for analyzing its financial performance since (i) share-based compensation does not require settlement in cash and (ii) deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement. However, DNII is a non-U.S. GAAP measure and should not be considered as a replacement for NII and other earnings measures presented in accordance with U.S. GAAP. Instead, DNII should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. In order to reconcile estimated DNII per share to estimated NII per share in accordance with U.S. GAAP for the fourth quarter of 2025, an estimated $0.07 per share of non-cash compensation expenses are added back to estimated NII to calculate estimated DNII per share.

(2)  DNII before taxes is NII before taxes as determined in accordance with 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 DNII before taxes per share is useful and appropriate supplemental disclosure for analyzing its financial performance since (i) share-based compensation does not require settlement in cash, (ii) deferred compensation expense or benefit does not result in a net cash impact to Main Street upon settlement and (iii) tax expenses may include (a) excise tax expense, which is not solely attributable to NII, and (b) deferred taxes, which are not payable in the current period. However, DNII before taxes is a non-U.S. GAAP measure and should not be considered as a replacement for NII, NII before taxes and other earnings measures presented in accordance with U.S. GAAP. Instead, DNII before taxes should be reviewed only in connection with such U.S. GAAP measures in analyzing Main Street's financial performance. In order to reconcile estimated DNII before taxes per share to estimated NII per share in accordance with U.S. GAAP for the fourth quarter of 2025, an estimated $0.07 per share of non-cash compensation expenses and an estimated $0.02 per share of NII related tax expenses are added back to estimated NII to calculate estimated DNII before taxes per share.

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

(4)  No information contained on the Company's website or disclosed on the February 27, 2026 conference call, including the webcast and the archived versions, is incorporated by reference in this press release or any of the Company's filings with the SEC, and you should not consider that information to be part of this press release or any other such filing.
