These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in PPG's 2022 Annual Report on Form 10-K (the "2022 Form 10-K"). Net sales, expenses, assets and liabilities can vary during each quarter of the year. Accordingly, the results of operations for the three months ended March 31, 2023 and the trends in these unaudited condensed consolidated financial statements may not necessarily be indicative of the results to be expected for the full year. Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on our previously reported Net income, total assets, cash flows or shareholders’ equity.
