Hercules Technology Growth Capital Announces Intention to Partially Redeem its 7.00% Senior Unsecured Notes due 2019

Hercules Technology Growth Capital, Inc. (NYSE: HTGC) (“Hercules” or the “Company”), the leading specialty finance company focused on providing senior secured loans to venture capital-backed companies in technology-related markets, including technology, biotechnology, life science, and energy & renewable technology, at all stages of development, today announced its intent to redeem $20.0 million (face value) of the $84.5 million in issued and outstanding aggregate principal amount of the Company’s 7.00% Senior Unsecured Notes due 2019 (CUSIP No. 427096888) (the “Notes”), which were issued pursuant to the indenture dated as of March 6, 2012, between the Company and U.S. National Bank Association, as trustee, as supplemented by the First Supplemental Indenture dated as of April 17, 2012 (the “Indenture”). The partial retirement of the Notes will result in certain interest savings if the Notes were otherwise left outstanding through maturity but will also accelerate the amortization of certain underwriting fees 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 2015, depending on its anticipated cash needs. The Company will provide notice for and complete all redemptions in compliance with the terms of the Indenture.
