Reason
Canaccord analyst John Newman lowered the firm's price target on Regeneron to $875 from $1,057 and keeps a Buy rating on the shares. The firm updated its model following its Phase 3 study of fianlimab+cemiplimab vs pembrolizumab failed to hit statistical significance on the primary endpoint of progression-free survival (PFS), a surprising and disappointing event.

Wolfe Research analyst Alexandria Hammond lowered the firm's price target on Regeneron to $860 from $900 and keeps an Outperform rating on the shares. The company's LAG-3 trial missed its primary endpoint, and while the opdualag head-to-head trial may presented a path forward through the FDA, the firm is less optimistic, the analyst tells investors in a research note. Commercial execution will be important for Regeneron going forward, while 2H26 catalysts may be underappreciated, the firm adds.
