with up to an additional approximately USD50 million of gross proceeds upon cash exercise of warrants, before deducting 
placement agent fees and offering expenses. 
 
The PIPE financing was led by a leading biotechnology investor associated with one of the largest alternative asset

HARPOON THERAPEUTICS ANNOUNCES UP TO USD150 MILLION PRIVATE PLACEMENT 
 
SOUTH SAN FRANCISCO, Calif., Oct. 23, 2023 (GLOBE NEWSWIRE) -- Harpoon Therapeutics, Inc. (NASDAQ: HARP) (the 
"Company"), a clinical-stage immunotherapy company developing novel T cell engagers, today announced that it has 
entered into a securities purchase agreement for a private placement in public equity ("PIPE") financing that is 
expected to result in upfront gross proceeds of approximately USD100 million, with up to an additional approximately USD50 
million of gross proceeds upon cash exercise of warrants, before deducting placement agent fees and offering expenses. 
The PIPE financing was led by a leading biotechnology investor associated with one of the largest alternative asset

Pursuant to terms of the securities purchase agreement, at the closing of the financing, the Company will issue an 
aggregate of 17,167,350 shares of its common stock (or pre-funded warrants in lieu thereof) and accompanying warrants 
to purchase up to an aggregate of 8,583,675 shares of its common stock, at a combined purchase price of USD5.8345 per 
share and accompanying warrant. Each full warrant will represent the right to purchase one share of the Company's 
common stock at an exercise price of USD5.8345 per share. In lieu of shares of common stock, certain investors are 
purchasing pre-funded warrants at a combined purchase price of USD5.8344 per share and accompanying warrant, which equals 
the purchase price per share of common stock and accompanying warrant, less the USD0.0001 per share exercise price of 
each pre-funded. The accompanying warrants will be exercisable upon issuance for a period of three years following the 
date of issuance. The accompanying warrants are only exercisable in cash. The PIPE financing is being conducted in

ongoing as well as future late-stage clinical studies of HPN328. The proceeds will also be used for working capital and 
other general corporate purposes. The aggregate proceeds from this financing, combined with current cash and cash 
equivalents, are expected to be sufficient to fund the current operating plan into 2026. 
 
TD Cowen is acting as the lead placement agent for the PIPE financing. Canaccord Genuity and H.C. Wainwright & Co. are 
also acting as placement agents for the PIPE financing.

About Harpoon Therapeutics 
Harpoon Therapeutics is a clinical-stage immunotherapy company developing a novel class of T cell engagers that harness 
the power of the body's immune system to treat patients suffering from cancer and other diseases. T cell engagers are 
engineered proteins that direct a patient's own T cells to kill target cells that express specific proteins, or 
antigens, carried by the target cells. Using its proprietary Tri- specific T cell Activating Construct (TriTAC®) 
platform, Harpoon is developing a pipeline of novel TriTACs initially focused on the treatment of solid tumors and 
hematologic malignancies. Harpoon has also developed a proprietary ProTriTACT platform, which applies a prodrug concept 
to its TriTAC platform to create a therapeutic T cell engager that remains inactive until it reaches the tumor. 
Harpoon's third proprietary technology platform, extended release TriTAC-XR, is designed to mitigate cytokine release 
syndrome. For additional information about Harpoon Therapeutics, please visit www.harpoontx.com.
