Take a look at some of the biggest movers in the premarket:
BioNTech (BNTX) – The drugmaker’s shares slid 3.4% in the premarket despite reporting better-than-expected quarterly profit and revenue. Results were down sharply from a year ago, with both profit and revenue off more than 40% from 2021’s third quarter.
Berkshire Hathaway (BRK.b) – Berkshire Hathaway gained 1.5% in premarket trading after Warren Buffett’s firm reported better-than-expected earnings, with revenue also topping Street forecasts. Berkshire reported an overall loss, however, as a falling stock market ate into the value of its investment portfolio.
Apple (AAPL) – Apple shares slid 1.8% in the premarket after it said Covid-19 restrictions are hindering iPhone production at the Foxconn factory in China. That factory is the world’s biggest iPhone production site.
Yamana Gold (AUY) – Yamana Gold lost 2.7% in the premarket after Gold Fields (GFI) said it would not change the terms of its takeover deal with Yamana. Agnico Eagle Mines (AEM) and Pan American Silver (PAAS) submitted a rival offer Friday, but Gold Fields maintains that its bid is superior.
Ouster (OUST) – The maker of lidar sensors will combine with rival Velodyne (VLDR) in a merger of equals, with Ouster and Velodyne shareholders each owning 50% of the combined company. Ouster jumped 5.1% in premarket action while Velodyne rallied 5.6%.
DoorDash (DASH) – The delivery service’s shares were upgraded to “outperform” from “perform” at Oppenheimer, which pointed to improving margins at U.S. restaurants among other factors. DoorDash gained 2.7% in premarket trading.
Okta (OKTA) – The maker of identity management software jumped 3.9% in the premarket after Guggenheim upgraded the stock to “buy” from “neutral.” It called the stock’s current valuation “too compelling to ignore.”
