Exhibit 99.2

Hercules Technology Growth Capital Announces Intention to Partially Redeem

its 7.00% Senior Unsecured Notes due September 2019

Palo Alto, Calif., November 4, 2015 – Hercules Technology Growth Capital, Inc. (NYSE: HTGC)(“Hercules” or the “Company”), the leading specialty financing provider to innovative venture growth stage companies backed by leading venture capital firms, today announced it intends to redeem $40.0 million (face value) of the $85.9 million in issued and outstanding aggregate principal amount of the Company’s 7.00% Senior Unsecured Notes due September 2019 (CUSIP No. 427096870) (the “Notes”), which were issued pursuant to the indenture (the “Base Indenture”) dated as of March 6, 2012, between the Company and U.S. National Bank Association, as trustee, as supplemented by the second supplemental indenture dated as of September 24, 2012 (together with the Base Indenture, the “Indenture”). The partial redemption of the Notes will result in interest expense savings if the Notes were otherwise left outstanding through maturity, but will also accelerate the amortization of certain underwriting fees and other debt issuance costs resulting in an increase in related expenses in the period the Notes are redeemed. Hercules currently intends to make additional redemptions on the Notes throughout calendar year 2016, depending on its anticipated liquidity position. The Company will provide notice for, and complete all, redemptions in compliance with the terms of the Indenture.
