Main Street Capital (NYSE: MAIN) boosts 2026 income with Q2 and supplemental dividends

Rhea-AI Filing Summary

Main Street Capital Corporation announced its Board declared regular monthly cash dividends of $0.26 per share for each of April, May and June 2026. These payments total $0.78 per share for the second quarter and match the first quarter level, while being a 4.0% increase from second quarter 2025 regular dividends.

The Board also approved a supplemental cash dividend of $0.30 per share payable in March 2026, funded from undistributed taxable income as of December 31, 2025.

Insights

Dividend and income-focused equities analyst

Main Street combines stable monthly dividends with an additional supplemental payout.

Main Street Capital is reinforcing its income profile by maintaining second quarter 2026 monthly dividends at $0.26 per share and adding a $0.30 supplemental dividend. The company highlights a 4.0% increase versus second quarter 2025 regular dividends and emphasizes consistent, unreduced monthly payouts since its 2007 IPO.

These declarations bring cumulative dividends to $49.015 per share since listing, and imply a 7.6% annualized current yield using the $56.78 share price on February 23, 2026. Sustainability depends on continued taxable income generation and regulatory requirements, as suggested by the reference to undistributed taxable income and future tax character determinations.

Investors relying on this income stream may pay attention to future disclosures on taxable income, dividend coverage, and any updates to the mix of ordinary income, qualified dividends, capital gains, or return of capital in the final 2026 tax reporting.

Including all dividends declared to date, including the second quarter 2026 regular monthly dividends

and the March 2026 supplemental dividend, Main Street will have paid $49.015 per share in

cumulative cash dividends since its October 2007 initial public offering at $15.00 per share. Including

the second quarter 2026 regular monthly dividends and the March 2026 supplemental dividend, these

most recent dividend declarations represent total dividends to Main Street shareholders of $1.08 per

share, representing an annualized current yield of 7.6% based on the closing price of $56.78 per share

The final determination of the tax attributes for dividends each year are made after the close of the tax

year. The final tax attributes for 2026 dividends are currently expected to include a combination of

ordinary taxable income and qualified dividends and may include capital gains and return of capital.

Main Street maintains a dividend reinvestment and direct stock purchase plan (the “Plan”). The

dividend reinvestment feature of the Plan (the “DRIP”) provides for the reinvestment of dividends on

behalf of Main Street’s registered stockholders who hold their shares with Main Street’s transfer agent

and registrar, Equiniti Trust Company, LLC, or certain brokerage firms that have elected to participate

in the DRIP. Under the DRIP, if Main Street declares a dividend, registered stockholders who have not

“opted out” of the DRIP by the dividend record date will have their dividend automatically reinvested

into additional shares of Main Street common stock. The direct stock purchase feature of the Plan (the

“DSPP”) provides investors with a convenient and economical method to purchase shares of Main

Street common stock. More information about the Plan (including the DSPP prospectus) can be found

on the Main Street website (https://ir.mainstcapital.com/dividend-reinvestment-and-direct-stock-

purchase-plan).
