Check out the companies making headlines in the premarket Friday:
Amazon — A U.K. regulator is looking into the e-commerce giant’s investment in food-delivery start-up Deliveroo. The Competition and Markets Authority said Friday it has “reasonable grounds” for suspecting the two companies could “cease to be distinct. ” This would give the regulator the authority to block Amazon’s $575 million investment.
Qualcomm, Micron Technology — Chipmakers fell broadly in the premarket after Samsung warned its second-quarter earnings likely plunged more than 50% from the previous year. Samsung cited weak demand for memory chips for the grim guidance.
Alexion Pharmaceuticals — The company announced the European Commission approved marketing for ULTOMIRIS, a drug used to treat paroxysmal nocturnal hemoglobinuria in adults. The U.S. Food and Drug Administration approved Alexion’s drug in December of last year.
