Regeneron Pharmaceuticals Inc (REGN) Valuation

GoodMoat Analysis

Based on data as of March 26, 2026

Regeneron appears deeply undervalued based on the GoodMoat Target, offering a significant margin of safety. However, its current valuation multiples are low relative to its historical average and the sector, which may reflect concerns about near-term growth. The assessment is favourable from a price perspective but requires caution regarding the business's growth trajectory.

Read full analysis
From a valuation perspective, Regeneron presents a compelling case. The current price of $749.47 is approximately 46% below the GoodMoat Target of $1,382.84. According to the framework's DCF bands, a margin of safety greater than 40% qualifies as 'Deeply Undervalued,' making the current price appear highly favourable. The P/E ratio of 17.5x is notably below the broader biotechnology sector average, which often trades above 20x, and is likely at the lower end of Regeneron's own historical range, suggesting the stock is cheap on an earnings basis. The Free Cash Flow Yield of 5.2% also indicates solid cash generation relative to its market price. However, this low valuation exists alongside a modest revenue growth rate of 2.5% YoY. For a value investor, the key question is whether this low price adequately compensates for the potential growth challenges. The stock is cheap on an absolute and relative basis, but its quality as a growth investment is muted by the current growth metrics. The valuation is favourable, but the investment thesis hinges on the durability of its earnings and potential for re-acceleration, not just the low multiple.
