Page 26 Internally Managed BDC Advantages • We operate under a shareholder friendly Internally Managed structure which: • Aligns management incentives with long term sustainable shareholder value creation • Historically has rewarded performing Internally Managed BDCs with price to book premiums of 0.5x versus Externally Managed peers • Incurs lower operating expenses versus the Externally Managed Structure • Average of 1.9%1 for Internally Managed BDCs vs. 3.0%1 for similarly sized Externally Managed BDCs • Management is targeting a long-term operating expense ratio of less than 2.0% of assets • LTM Operating Leverage of 1.9% as of 3/31/23 • Senior personnel and corporate infrastructure already in place; Management plans to conservatively add junior members to the team in lock step with growth in the asset base • With the passage of the BDC Modernization Act, virtually 100% of incremental levered returns will go directly to shareholders of Internally Managed BDCs in the form of dividends, while only a portion of the incremental levered returns will translate into increased dividends to shareholders of Externally Managed BDCs • Externally Managed BDCs pay incremental management and incentive fees on incremental dollars invested • Internally Managed BDCs do not have management or incentive fee structures (1) Internally managed BDCs include MAIN and HTGC.
