 Shares of Molson Coors Beverage Co. sank 3.1 in premarket trading Thursday, after the beer brewer reported a fourth-quarter adjusted profit and sales that missed expectations, weighed by weakness in Europe amid further on-premise restrictions in the U.K. amid a surge in COVID-19 cases. On a net basis, the company swung to a net loss of 1.37 billion, or 6.32 a share, from income of 163.7 million, or 75 cents a share, in the year-ago period.
