Main Street’s preliminary estimate of net asset value (“NAV”) per share as of June 30, 2025 is
$32.27 to $32.33, representing an increase of $0.24 to $0.30 per share, or 0.7% to 0.9%, from the
NAV per share of $32.03 as of March 31, 2025, with this increase after the impact of the
supplemental dividend paid in June 2025 of $0.30 per share. The estimated increase in NAV per
share is primarily due to the net fair value increase on the investment portfolio and the accretive
impact of equity issuances, partially offset by a decrease due to the issuance of restricted stock.
The net fair value increase on the investment portfolio is the result of net fair value increases on
the wholly-owned asset manager and the lower middle market (“LMM”) investment portfolio,
partially offset by net fair value decreases on the private loan and middle market investment
portfolios.
As a result of Main Street’s preliminary estimates of NII and the net changes in the fair value of
its investment portfolio as noted above, Main Street estimates that it generated a quarterly
annualized return on equity of over 17% for the second quarter of 2025.(3)
Main Street preliminarily estimates that investments on non-accrual status comprised 2.1% of the
total investment portfolio at fair value and 5.0% at cost as of June 30, 2025.
