PPG Industries (PPG) Stock Analysis & Winston Score

PPG Industries makes paints, coatings, and specialty materials used on cars, airplanes, buildings, and industrial equipment. Its products protect surfaces from rust, weather, and wear. PPG sells to automakers, aerospace companies, construction firms, and everyday consumers through brands like PPG, Glidden, and Olympic. The company earns money by selling its coatings and paints to manufacturers and through retail stores across more than 70 countries. PPG is one of the largest coatings companies in the world, competing mainly with Sherwin-Williams and AkzoNobel. Its moat comes from long-term customer relationships, proprietary formulas, and the high cost of switching suppliers in industries like aerospace and automotive. The main risk PPG faces is that its raw material costs — especially resins and solvents derived from oil — can rise quickly, squeezing profit margins when the company cannot pass those costs on to customers fast enough.
