Source and what to watch
The figures and dividend declarations are from Main Street Capital’s Q3 results release and its 5 November Form 8-K, checked on 6 November 2026. Dividend eligibility and payment mechanics should be read from the issuer’s official notices.
Readers comparing the figures should not add the supplemental dividend to the regular monthly dividend amount as though they were the same recurring payment. The release identifies the supplemental amount separately.
