Check out the companies making headlines in premarket trading: Bristol-Myers Squibb — The biopharmaceutical stock jumped 5.3% after the U.S. Food and Drug Administration approved Cobenfy as a treatment of schizophrenia for adults. It marks the first new type of treatment for the mental disorder in several decades. Novo Nordisk — U.S.-listed shares of the Danish health-care company slid 2.9% after JPMorgan said to expect a lower sales figure than Wall Street expects for the third quarter. The bank said that is due in part to its weaker-than-typical forecast for blockbuster weight-loss drug Wegovy. Costco Wholesale — The membership-only retailer saw shares dip about 1% after the company missed expectations for fiscal fourth-quarter revenue. Revenue came in at $79.70 billion, below an analyst average estimate of $79.97 billion, per LSEG. Costco was hurt by cautious consumer spending on pricier items as well as falling gasoline prices. Super Micro Computer — Shares of the artificial intelligence beneficiary slipped 2%, adding to their 12% loss in the previous session.
