What happened

Regeneron (REGN) stock jumped about 11.5% to roughly $913 on Friday after reporting a third-quarter earnings beat and raising its 2026 outlook, driven by Dupixent sales. Revenue rose 36% from a year ago to $5.1 billion, well above the $4.6 billion analysts expected. Adjusted profit per share was $20.07, versus $16.25 expected. Dupixent, an asthma and eczema drug sold with partner Sanofi, brought in $6.5 billion worldwide, up 35%. Regeneron also raised its own forecast (guidance) for 2026 profit margin on product sales to about 86%, from 84%–85%.

Why it matters

Regeneron's quarter shows its biggest drug, Dupixent, is still growing fast, and more cash is on the way. A widened deal with Sanofi brings $1.0 billion up front in the fourth quarter, plus up to $7.0 billion more if goals are met. Its newer eye drug, EYLEA HD, rose 62% while the older version lost sales to cheaper copies. If the gain holds, the stock would reach its highest level since October 2024.
