Sanofi ADR looks cheaper on two of the three valuation measures in this snapshot. BeiGene has the lower PEG and higher return on equity, so the comparison isn’t one-sided.

Sanofi ADR (SNY) and BeiGene, Ltd. (ONC) are both in Health Care, within Pharmaceuticals, Biotechnology & Life Sciences. At the October 30, 2026 adjusted close, SNY was US$44.34, with a market cap of US$106.2B. ONC was US$370.33, with a market cap of US$42.1B. Share prices alone don’t show which company is cheaper. The valuation multiples offer a more useful, though incomplete, comparison.

Investor takeaway: Sanofi has the lower P/E and P/B, while BeiGene has the lower PEG. Sanofi comes out ahead on two of the three available multiples. That doesn’t prove SNY is undervalued, ONC is overvalued, or either stock will outperform. The measures reflect different aspects of valuation and should be considered alongside each company’s performance and risks.

Sanofi is cheaper on two of three supplied multiples

SNY has the lower P/E (22.1 versus 66.2) and P/B (1.30 versus 8.09). ONC has the lower PEG (0.78 versus 31.46). Sanofi looks cheaper on more of these measures, but the split shows why no single multiple can settle the question of value.

Bull case

Sanofi’s lower P/E of 22.1 and P/B of 1.30 may appeal to investors comparing these multiples. Its analyst consensus is Buy, with a target price of US$53.61.

Bear case

Sanofi’s PEG is 31.46, well above BeiGene’s 0.78. Its trailing return on equity is also lower: 5.7% versus 14.7% for BeiGene. These figures add context to Sanofi’s lower P/E and P/B, but this snapshot doesn’t explain the differences.

The valuation table mostly favours Sanofi

Sanofi has the lower P/E and P/B: 22.1 versus 66.2 for P/E, and 1.30 versus 8.09 for P/B. The PEG comparison favours BeiGene, at 0.78 versus Sanofi’s 31.46. Sanofi therefore looks cheaper on two of the three multiples, but these measures don’t establish either company’s intrinsic value or capture every difference between them.

Returns, analyst ratings and company size add context

BeiGene’s trailing return on equity is 14.7%, compared with 5.7% for Sanofi. That difference may matter when weighing Sanofi’s lower P/E and P/B against BeiGene’s lower PEG. The snapshot doesn’t explain what’s driving the figures or how they may change. Both stocks have a dividend yield of 0.00%.

The analyst consensus ratings are Buy for Sanofi and Strong Buy for BeiGene. Their target prices are US$53.61 and US$436.46, respectively. These are estimates from this snapshot, not guarantees of future prices. Sanofi’s market cap is US$106.2B, compared with BeiGene’s US$42.1B. For company details, see Sanofi ADR and BeiGene.
