Hercules Capital Receives Baa3 Investment Grade Credit and Corporate Rating from Moody’s Investors Service

PALO ALTO, Calif., March 8, 2021 - Hercules Capital, Inc. (NYSE: HTGC) (“Hercules” or the “Company”), the largest and leading specialty financing provider to innovative venture, growth and established stage companies backed by some of the leading and top-tier venture capital and select private equity firms, today announced that Moody’s Investors Service, Inc. (“Moody’s”) has assigned Hercules an investment grade credit and corporate rating of Baa3 with a stable outlook.

“We are very pleased that Moody’s has initiated coverage with a Baa3 investment grade credit and corporate rating,” stated Scott Bluestein, chief executive officer and chief investment officer of Hercules. “This rating reflects our differentiated and diversified venture and growth stage lending and commitment to disciplined underwriting, as well as the depth and experience of our management and investment teams.”

The Baa3 rating reflects the Company’s strong earnings profile with a longer operating history than most rated business development company (“BDC”) peers, solid underwriting and risk management as evidenced by low loan loss history, adequate liquidity profile, and low leverage with ample cushion against the minimum regulatory 150% asset coverage ratio. The rating also reflects Hercules’ high proportion of first lien senior secured debt investments.
