 Perrigo Plc PRGO, -1.00 , the Dublin-based consumer self-care products maker, posted weaker-than-expected third-quarter earnings on Wednesday and issued a profit warning for the full year, after the pandemic added to supply chain issues to leave it with the most unshipped orders ever amid a shortage of trucks and drivers. Perrigo posted a loss of 54 million, or 40 cents a share, for the quarter, after income of 26 million, or 19 cents a share, in the year-earlier period.
