Investment Thesis

Harpoon Therapeutics presents a notable research candidate due to its innovative TriTAC platform and promising clinical pipeline. The company's lead product candidates, including HPN328, HPN217, and HPN536, are in Phase I/II clinical trials, demonstrating initial safety and efficacy signals. The collaboration with AbbVie Biotechnology Ltd. validates the potential of the TriTAC platform and provides financial resources for further development. With a gross margin of 90.3%, Harpoon has the potential for significant profitability upon commercialization of its products. The current market cap of $0.87 billion may undervalue the long-term potential of the company's pipeline and technology. Upcoming clinical trial results and potential partnerships could serve as catalysts for stock appreciation.
