Exhibit 99.3

Hercules Capital Announces Fiscal 2021 Supplemental Cash Distribution of $0.28 per Share

Supplemental Cash Distribution is in Addition to the Regular Quarterly Cash Distributions and will be Distributed Equally over Four Quarters Beginning with the First Quarter Distribution Payable in May 2021

PALO ALTO, Calif., April 27, 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, is pleased to announce that its Board of Directors has declared a supplemental cash distribution of $0.07 per share for the first quarter of 2021.

This supplemental cash distribution will be paid out of Hercules Capital’s undistributed taxable income (taxable income in excess of distributions paid) as of March 31, 2021. The following shows the key dates of the supplemental distribution payment:

This supplemental cash distribution is in addition to the previously announced regular quarterly cash distribution that Hercules declared for the first quarter of 2021 of $0.32 per share.

Hercules' Board of Directors maintains a variable distribution policy with the objective of distributing four quarterly distributions in an amount that approximates 90% to 100% of the Company’s taxable quarterly income or potential annual income for a particular year. In addition, during the year, the Company’s Board of Directors may choose to pay additional supplemental distributions, so that the Company may distribute approximately all its annual taxable income in the year it was earned, or it can elect to maintain the option to spill over the excess taxable income into the coming year for future distribution payments.

The determination of the tax attributes of the Company's distributions is made annually as of the end of the Company's fiscal year based upon its taxable income for the full year and distributions paid for the full year. Therefore, a determination made on a quarterly basis may not be representative of the actual tax attributes of its distributions for a full year. Of the distributions declared during the quarter ended March 31, 2021, 100% were distributions derived from the Company’s current and accumulated earnings and profits. There can be no certainty to stockholders that this determination is representative of the tax attributes of the Company’s 2021 full year distributions to stockholders.

Pursuant to Internal Revenue Code Section 871(k), certain funds generate “Qualified Interest Income” (QII) that may be exempt for U.S. withholding tax on foreign accounts. A regulated investment company (“RIC”) is permitted to designated distributions of QII as exempt from U.S. withholding tax when paid to non-U.S. shareholders with proper documentation.

The percentage of QII for distributions declared for the first quarter ended March 31, 2021 on Hercules Capital, Inc.’s common stock is 88.7%.
