Main Street Capital stands out as a top-performing BDC, driven by its internally managed structure and focus on the lower middle market. MAIN consistently compounds NAV per share and delivers robust ROE, recently pre-announcing 17%+ annualized ROE and distributable net investment income above consensus. The firm's differentiated model—equity participation, conservative balance sheet, and a growing fee-based asset management business—justifies its premium 1.8x price-to-NAV valuation.
