Listen to the news

Regeneron Pharmaceuticals (REGN) has drawn investor attention after its recent share price move, with the stock closing at $776.31. That shift is prompting fresh interest in how its fundamentals stack up today.

See our latest analysis for Regeneron Pharmaceuticals.

The recent 1 month share price return of 8.07% and 3 month share price return of 33.10% suggest momentum has been building, while a 1 year total shareholder return of 8.98% points to steadier progress over a longer stretch.

If Regeneron has you looking more closely at healthcare, this could be a good moment to scan healthcare stocks for other names showing solid longer term performance profiles.

With Regeneron trading at $776.31 and an intrinsic value estimate implying roughly a 54% gap, along with annual revenue of US$14.25b and net income of US$4.58b, is the market leaving upside on the table or already pricing in future growth?

Most Popular Narrative: 60% Undervalued

At a last close of $776.31 versus a narrative fair value near $781, the current setup is framed as materially undervalued with modest upside implied.

Regeneron's broad and advancing pipeline including recent or upcoming pivotal data in immunology, oncology (notably Lynozyfic and odronextamab), genetic medicines, and obesity positions the company to benefit from demographic driven increases in demand for advanced therapies and from the rise in personalized and precision medicine, supporting future revenue growth and pipeline driven earnings upside.

Curious what kind of revenue build, margin profile, and future P/E multiple are baked into that fair value line? The narrative leans on steady expansion, disciplined profitability assumptions, and a higher earnings multiple than today. The exact mix of growth, margins, and discount rate is where the story really gets interesting.

Result: Fair Value of $781.13 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, the story could shift quickly if EYLEA headwinds intensify or if regulators delay key EYLEA HD and pipeline approvals that underpin the current upside case.
