Hercules Announces That an Additional $23.1 Million of Its 6.00% Convertible Senior Notes Due 2016 Have Converted

Approximately $17.8 million of the notes remain outstanding

Hercules Technology Growth Capital, Inc. (NYSE:HTGC), 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 industries, at all stages of development, announced today that holders of an additional $23.1 million of its 6.00% Convertible Senior Notes due 2016 have exercised their conversion rights.

The trustee for the 6.00% Convertible Senior Notes due 2016 has informed Hercules that the additional $23.1 million brings the total principal amount of the notes that holders have exercised their conversion rights on to approximately $57.2 million. Conversion will be settled pursuant to the terms of the indenture. Hercules has elected to settle the outstanding principal amount of the tendered notes in cash, and Hercules will issue shares of its common stock for the remainder of the settlement amount. As a result of these additional conversions in the fourth quarter, Hercules expects to incur a negative impact to earnings.

Upon meeting the stock trading price conversion requirement during the three months ended September 30, 2014, the Convertible Senior Notes continue to be convertible through December 31, 2014.

Remaining holders of outstanding Convertible Senior Notes interested in converting should follow the conversion procedures set forth in the indenture, which include, as applicable, providing notices and following the procedures required by the depository and the trustee.
