Health-care companies fell after a surprisingly weak report from one global drug-store chain.

Walgreens Boots Alliance slid to a seven-year low after the pharmacy chain said it plans to cut about 4,000 jobs in the U.K. and suspend stock buybacks, citing a hit to demand from the Covid-19 pandemic.

The pharmacy chain said the pandemic reduced sales by $700 million to $750 million for the quarter ended May 31. Shares of NanoViricides fell after the drug developer sold shares in a follow-on offering.
