📋 What This Means for MAIN Shareholders

Main Street Capital Corporation (MAIN) has a DilutionScore of 65/100, placing it in the High dilution risk tier. This score reflects at least one active dilution mechanism — a shelf registration, ATM program, outstanding warrants, or limited cash runway — that could materially increase the share count over the next 12–18 months. Score as of July 13, 2026, updated from SEC EDGAR data.

Cash runway is a key watch item: MAIN has approximately 1 months of runway at current burn rate. Companies with less than 18 months of runway are statistically more likely to file new shelf registrations or ATM programs within the next two quarters.
