TL;DR: Director reinvested dividends to acquire small incremental share amounts; transactions are routine and disclosed under Section 16.

The Form 4 documents two dividend reinvestment purchases on 07/15/2025 totaling 187.794 shares cumulatively added across two reported entries (51.254 and 136.54 shares) at approximately $63.50 per share and resulting in reported beneficial holdings near 47.5k shares. These purchases are reported under a Rule 16a-11 exempt reinvestment process, indicating automated reinvestment rather than discretionary open-market trades. For investors, this is a routine insider activity that updates beneficial ownership but contains no new operational or financial information about MAIN.
