The CEO of PPG Industries, Michael H. McGarry, said, "As we communicated in early September, supply-chain disruptions worsened during the quarter as various commodity and component shortages restricted both our manufacturing output and that of certain customers. Several of our businesses, including automotive refinish, protective and marine, and packaging coatings delivered above-market volume performance despite the procurement challenges. In addition, demand recovery continued in our aerospace coatings business, primarily in the aftermarket." (See PPG stock chart on TipRanks)
