A big drop in profits is spurring Walgreens Boots Alliance — which was already trying to reinvent itself before COVID-19 — to enhance pickup options for the drugstore chain’s customers and again withhold full bonuses from employees.

The Deerfield-based company said Thursday that it earned $373 million in its fiscal fourth quarter that ended Aug. 31, down nearly 45% from the year-ago period. That was an improvement, however, from the third quarter, in which Walgreens lost $1.7 billion during the early months of COVID-19.
