PPG Acquires AkzoNobel’s North American Architectural Coatings Business Charles E. Bunch – Chairman of the Board and Chief Executive Officer David B. Navikas – Senior Vice President Finance and Chief Financial Officer J. Rich Alexander – Executive Vice President Global Architectural Coatings Information current as of December 14, 2012 Exhibit 99.1

Forward Looking Statement 2 Statements contained herein relating to matters that are not historical facts are forward-looking statements reflecting PPG’s current view with respect to future events and financial performance. These matters within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, involve risks and uncertainties that may affect PPG’s operations, as discussed in PPG’s filings with the Securities and Exchange Commission pursuant to Sections 13(a), 13(c) or 15(d) of the Exchange Act, and the rules and regulations promulgated thereunder. Accordingly, many factors could cause actual results to differ materially from the forward-looking statements contained herein. Such factors include global economic conditions, increasing price and product competition by foreign and domestic competitors, fluctuations in cost and availability of raw materials, the ability to maintain favorable supplier relationships and arrangements, the realization of anticipated cost savings from restructuring initiatives, difficulties in integrating acquired businesses and achieving expected synergies therefrom, economic and political conditions in international markets, the ability to penetrate existing, developing and emerging foreign and domestic markets, foreign exchange rates and fluctuations in such rates, fluctuations in tax rates, the impact of future legislation, the impact of environmental regulations, unexpected business disruptions, and the unpredictability of existing and possible future litigation, including litigation that could result if the asbestos settlement discussed in PPG’s filings with the Securities and Exchange Commission does not become effective. This presentation also contains statements about PPG’s Agreement to purchase the North American architectural coatings business of AkzoNobel (the “Akzo Transaction”) and PPG’s agreement to separate its commodity chemicals business and merge it with a subsidiary of Georgia Gulf Corporation (the “Georgia Gulf Transaction” and together with the Akzo Transaction, the “Transactions”). Many factors could cause actual results to differ materially from the company’s forward-looking statements with respect to the Transactions, including, the parties’ ability to satisfy the conditions to the closing of the Transactions; the parties’ ability to complete the Transactions on anticipated terms and schedule, the ability of Georgia Gulf to obtain shareholder approval of the Georgia Gulf Transaction, the anticipated tax treatment of the Georgia Gulf Transaction; risks relating to the ability of the parties to obtain regulatory approvals for the Transactions, any unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses and future prospects; business and management strategies for the management, expansion and growth of PPG’s operations; PPG’s ability to integrate the North American architectural coatings business of AkzoNobel after the closing and to achieve anticipated synergies; and the risk that disruptions from the Transactions will harm PPG’s business. However, it is not possible to predict or identify all such factors. Consequently, while the list of factors presented here and in PPG’s Form 10-K for the year ended December 31, 2011 are considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on PPG’s consolidated financial condition, results of operations or liquidity. All information in this presentation speaks only as of December 14, 2012, and any distribution of this presentation after that date is not intended and will not be construed as updating or confirming such information. PPG undertakes no obligation to update any forward-looking statement, except as otherwise required by applicable law.
