Mark Kowlzan

Mark Kowlzan has served as Chairman and CEO of Packaging Corporation of America (PCA) since 2010, having spent his entire career at the company starting from engineering roles in PCA's paper mills. His deep operational expertise in paper manufacturing is evident in PCA's consistently best-in-class production costs — PCA's mills are among the most efficient in the U.S. containerboard industry. PCA is the third-largest producer of containerboard and corrugated packaging products in the United States, behind International Paper and WestRock (now Smurfit Westrock). The company operates a vertically integrated model: manufacturing containerboard (linerboard and corrugated medium) at its mills and converting it into corrugated boxes at a network of converting plants. Containerboard is the brown cardboard used to make corrugated shipping boxes — a product that benefits enormously from the structural growth of e-commerce, as every online order requires packaging. Under Kowlzan's leadership, PCA has maintained a disciplined strategy: focusing on operational efficiency at its mills, investing in converting plant capacity to serve growing customer demand, and returning substantial cash to shareholders through dividends and buybacks. The company has avoided the mega-merger temptation that has consolidated much of the industry, preferring organic growth and small bolt-on acquisitions. Key variables for PCA's stock include containerboard pricing (influenced by supply/demand dynamics and input costs like recycled fiber and energy), e-commerce volume growth, industrial production trends, and Kowlzan's continued capital discipline.
