Graphic Packaging Holding Company (NYSE: GPK), a global leader in sustainable consumer packaging, has been recognized among America's leading corporate citizens, ranking No. 5 overall and No. 1 in the materials sector on 3BL's 2026 100 Best Corporate Citizens list. The recognition reflects Graphic Packaging's long-standing commitment to community, environment and governance leadership — an important foundation for the company's next phase of business optimization and growth.

Since 1999, the ranking has assessed the 1,000 largest publicly traded U.S. companies based on their performance and transparency across key areas of corporate citizenship. Graphic Packaging also earned top-five rankings in both environment and human rights, reflecting strong performance in areas including resource efficiency, responsible sourcing and human rights due diligence throughout its value chain.

"We are honored to rank among the top five and first in the materials sector on the 2026 100 Best Corporate Citizens list," said Robbert Rietbroek, president and chief executive officer of Graphic Packaging. "This recognition reflects the high standards our teams uphold and our continued focus on operational excellence as we deliver sustainable packaging that helps our customers advance their environmental and business goals."

The 3BL recognition adds to several independent honors Graphic Packaging received in 2026, including:

• 2026 World's Most Ethical Companies® by Ethisphere
• World's Most Admired Companies by Fortune
• Top 100 companies for 2026 by JUST Capital

While each recognition is based on a distinct methodology, together they reflect a consistent record of performance across ethics, sustainability, transparency and corporate citizenship.
