Assembly Biosciences stock receives Buy rating from H.C. Wainwright

Investing.com - H.C. Wainwright assumed coverage on Assembly Biosciences (NASDAQ:ASMB) with a Buy rating and a $50.00 price target on Monday. The stock, currently trading at $25.44, has shown remarkable momentum with a 104% gain over the past six months, according to InvestingPro data.

The research firm cited the potential of Assembly’s clinical-stage antiviral pipeline to deliver significant value through its collaboration with Gilead Sciences (NASDAQ:GILD). The pipeline features oral therapies for hepatitis D virus (HDV) and herpes simplex virus (HSV). With a market capitalization of $396 million and impressive revenue growth of 55% in the last twelve months, Assembly is attracting increased investor attention.

H.C. Wainwright highlighted two lead programs: ABI-6250, an oral HDV entry inhibitor for chronic HDV infection, and ABI-5366, an oral long-acting helicase-primase inhibitor for recurrent genital HSV infection. Both programs are advancing through Phase 1 trials with encouraging third-quarter 2025 interim data.

The firm models a 95% probability that Gilead will opt in to ABI-6250 and a 50% probability for ABI-5366, with decisions expected after Phase 2 trials. These opt-ins could provide substantial non-dilutive capital and position Assembly to elect its 40% U.S. profit-share structure.

H.C. Wainwright believes Assembly is well-positioned to generate significant upside from two high-value infectious disease franchises, with its $50 price target implying meaningful upside from current levels. InvestingPro analysis reveals a Strong Buy consensus among analysts, with price targets ranging from $29 to $35.
