WhiteHorse Finance, Inc. Amends Credit Facility with JP Morgan

Reduces Cash Balance, Supports Long-Term Leverage Target and Portfolio Composition Goals

NEW YORK, Nov. 20, 2018 – WhiteHorse Finance, Inc. (“WhiteHorse Finance” or the "Company") (NASDAQ:WHF) today announced that it has amended its existing credit facility with JP Morgan Chase (“JP Morgan”). The amendment allows for an increased advance rate, a temporary reduction in the minimum funding amount, and a decrease in the concentration of second lien loans. The new terms allow the Company to reduce its outstanding debt on the JP Morgan facility with the cash raised from the recent public offering of $35,000,000 aggregate principal amount of 6.50% notes due 2025. The Company believes this amendment positions the Company to achieve its long-term leverage target and portfolio composition goals.

Stuart Aronson, WhiteHorse Finance's Chief Executive Officer commented, “WhiteHorse Finance remains committed to its disciplined approach of sourcing transactions that generate attractive risk-adjusted returns consistent with the strong track record of our credit portfolio, all with the goal of enhancing value for our shareholders. JP Morgan continues to be a great partner as we position WhiteHorse Finance for growth.”
