Jefferies raises Regeneron price target to $930 on new $1B Sanofi partnership for antibody drugs

Jefferies increased its price target for Regeneron to $930, citing an expanded partnership with Sanofi to develop four new long-acting antibodies targeting inflammatory pathways. Sanofi will pay Regeneron $1 billion upfront, with potential milestone payments up to $7 billion, aiming to secure future revenue beyond Dupixent's exclusivity. This deal strengthens their pipeline with drugs expected to launch from 2030, supporting long-term growth amid competitive pressures. Regeneron's stock currently trades about 25.5% below the new target, reflecting significant upside potential.

Following Jefferies' price target increase for Regeneron, the stock trades at USD 740.17 on Pluang as of Oct 02, 2026 02:31 WIB, down 2.39% for the day and below its 52-week high of USD 852.03. Sanofi shares are priced at USD 40.87, down 0.89%, near their 52-week low of USD 40.74. On Pluang, Regeneron sees a buying interest with 71% of orders as of the same time.
