Horizon Technology Finance Announces

Monthly Distributions for July, August and September 2015

Totaling $0.345 Per Share

FARMINGTON, Conn., May 5, 2015 – Horizon Technology Finance Corporation (NASDAQ: HRZN) ("Horizon"), a leading specialty finance company that provides capital in the form of secured loans to venture capital backed companies in the technology, life science, healthcare information and services and cleantech industries, announced today that its board of directors declared monthly cash distributions of $0.115 per share payable in each of July, August and September 2015. These monthly distributions, payable as set forth in the table below, total $0.345 per share. Including the monthly distributions declared in the second quarter of 2015, Horizon has declared $6.995 per share in cumulative distributions since its October 2010 initial public offering.

Monthly Distributions Declared in Second Quarter 2015

When declaring distributions, the Horizon board of directors reviews estimates of taxable income available for distribution, which may differ from consolidated net income under generally accepted accounting principles due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of spillover income carried over from a given year for distribution in the following year. The final determination of taxable income for each tax year, as well as the tax attributes for distributions in such tax year, will be made after the close of the tax year.

Horizon maintains a “Dividend Reinvestment Plan” ("DRIP") that provides for the reinvestment of distributions on behalf of its stockholders, unless a stockholder has elected to receive distributions in cash. As a result, if Horizon declares a distribution, its stockholders who have not "opted out" of the DRIP by the distribution record date will have their distribution automatically reinvested into additional shares of Horizon’s common stock. Horizon has the option to satisfy the share requirements of the DRIP through the issuance of new shares of common stock or through open market purchases of common stock by the DRIP plan administrator. Newly-issued shares will be valued based upon the final closing price of Horizon’s common stock on a specified valuation date for each distribution as determined by Horizon’s board of directors. Shares purchased in the open market to satisfy the DRIP requirements will be valued based upon the average price of the applicable shares purchased by the DRIP plan administrator, before any associated brokerage or other costs, which are borne by Horizon.
