** Jefferies cuts Belgian biopharmaceutical group UCB UCB.BR to "underperform" from "buy", citing signs of slowing growth for its inflammation drug Bimzelx
** The broker sees 10%-15% downside to Bimzelx estimates from 2026 and beyond, due to recent slowing of U.S. volumes trends and a lower dynamic of the hidradenitis suppurativa, a chronic skin disease, market
** It notes the stock almost exclusively trades around Bimzelx's trajectory with 50% of the revenues in the 2030 consensus derived from the product
** "The stock is too expensive to tolerate a slowdown in growth, but granular volume analysis suggests Bimzelx-driven upgrades are unlikely in the near term," it adds
** Out of 21 analysts that cover UCB, 17 rate the stock "strong buy" or "buy, "three rate it "hold" and one rates the stock "strong sell" - LSEG data
