Clinical partnership puts Vir Biotechnology in focus

Vir Biotechnology (VIR) has drawn fresh attention after finalizing its collaboration with Astellas Pharma on VIR-5500 for prostate cancer and treating the first patient in an expansion cohort of its Phase 1 metastatic prostate cancer trial.

The recent collaboration news comes against a backdrop of strong momentum, with a 30 day share price return of 10.49% and a year to date share price return of 68.52%. However, the 1 year total shareholder return of 77.80% contrasts with deeper 3 and 5 year total shareholder losses.

With Vir Biotechnology trading at $10.01 against an average analyst price target of $20.78 and recent returns swinging from sharp multi year losses to strong 1 year gains, is this a reset buying opportunity or is the market already pricing in future growth?

Most Popular Narrative: 52% Undervalued

Vir Biotechnology's most followed narrative points to a fair value of $20.78 versus the last close at $10.01. This frames the recent share price rebound in a very different light.

The analysts have a consensus price target of $20.78 for Vir Biotechnology based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $30.0, and the most bearish reporting a price target of just $17.0.

Curious why a loss making company still screens as undervalued here? The core assumptions rest on brisk revenue expansion, margin repair and a premium future earnings multiple that is far from typical for this sector.

Result: Fair Value of $20.78 (UNDERVALUED)

However, investors still face important risks, including reliance on early stage oncology data and ongoing legal disputes, such as the Brii Biosciences arbitration.

Another way to look at Vir Biotechnology's valuation

Analysts see fair value around $20.78, but the current P/S of 23.5x tells a more cautious story. It is above the US Biotechs industry at 10.8x and well above the fair ratio of 0x, even though it sits below the peer average at 30.6x. Is the stock pricing in more success than the fundamentals currently support, or are investors leaning into the oncology and hepatitis delta potential?
