Walgreens Boots Alliance Inc.’s stock jumped 10% early Friday after the troubled drugstore chain posted another loss but blew past estimates on an adjusted basis and said it would continue to work on a turnaround.

The Deerfield, Illinois-based company WBA had a loss of $265 million, or 31 cents a share, for its fiscal first quarter to Nov. 30, wider than the loss of $67 million, or 8 cents a share, in the year-earlier period.
