Vir Biotechnology is a clinical-stage company with extraordinary analyst upside of 150% and an asymmetry ratio of 10.95x, but it has missed earnings in three of four recent quarters, burns cash at negative 328% of revenue, and scores below the minimum quality threshold at 1.9 out of 10, making it a speculative bet on late-stage clinical pipeline success.

About Vir Biotechnology, Inc.
About Vir Biotechnology, Inc.
Vir Biotechnology's most advanced program, the tobevibart-elebsiran antibody-siRNA combination for chronic hepatitis delta, entered registrational Phase 3 trials (ECLIPSE 1, 2, and 3) in March 2025, with topline results expected in the fourth quarter of 2026 and first quarter of 2027. The company also advances three Phase 1 T-cell engager oncology candidates and an HIV cure program. Vir held $781.6 million in cash and investments at December 31, 2025, following a $438.0 million net loss for the year and a $1.2 billion accumulated deficit.
Vir has no approved products generating meaningful revenue today; its combination of tobevibart and elebsiran for chronic hepatitis delta incorporates Xencor's Xtend Fc-extension technology and Vir's proprietary antibody engineering, while three oncology T-cell engager candidates (VIR-5500, VIR-5818, VIR-5525) rely on the exclusive PRO-XTEN masking platform in-licensed from Sanofi's Amunix Pharmaceuticals unit for worldwide oncology and infectious-disease rights. The company has out-licensed regional commercial rights for the CHD combination to Norgine (Europe, Australia, New Zealand) and granted Brii Biosciences an option for Greater China rights, while its HIV broadly neutralizing antibody program builds on antibodies in-licensed from Togontech GmbH with support from the Gates Foundation. Vir relies on third parties to manufacture clinical and, if approved, commercial drug supply, and to conduct and monitor its preclinical and clinical studies.
Show full overview
Vir's oncology ambitions run through a single external license: all three of its clinical-stage T-cell engagers depend on the PRO-XTEN masking technology that Vir exclusively in-licensed from Sanofi's Amunix unit, meaning a breach, dispute, or termination of that agreement could simultaneously impair VIR-5500, VIR-5818, and VIR-5525 rather than just one program. The 10-K's risk factors explicitly warn that breaching license agreements underlying acquired intellectual property could cost the company the ability to continue developing and commercializing the related candidates. That concentrates Vir's oncology pipeline risk in a counterparty relationship rather than in Vir's own proprietary science, a different risk profile than its infectious-disease programs, which rely more heavily on internally engineered antibodies.
