Koppers Named Among America's Most Responsible Companies By Newsweek for Fourth Consecutive Year

PITTSBURGH, Dec. 12, 2023 /PRNewswire/ -- Koppers Holdings Inc. (NYSE: KOP), an integrated global provider of treated wood products, wood treatment chemicals and carbon compounds, has been named as one of America's Most Responsible Companies by Newsweek magazine for the fourth consecutive year in 2024. Koppers ranked No. 124 out of 600 finalists and No. 13 out of 51 companies in the Materials & Chemicals category.

"Koppers is proud to again earn a space on this impressive list – a testament to the ongoing strength of our sustainability strategy, guided by our values of People, Planet and Performance," said Leslie Hyde, Koppers Senior Vice President and Chief Sustainability Officer. "We have continued to take significant steps to embed sustainability more deeply across all aspects of our business operations and achieve a growing sense of ownership among employees at all levels. We thank our 2,100 global employees whose work drives our accomplishments."

In 2023, Koppers released its annual Corporate Sustainability Report along with its first-ever Task Force on Climate-Related Financial Disclosures (TCFD) Report. Highlights outline how Koppers:

• Improved safety performance, with a 5 percent reduction in total recordable incident rate;
• Expanded investment in career growth and continuing education opportunities for employees through Koppers College;
• Reduced greenhouse gas emissions by 49 percent since the baseline year of 2007, nearly achieving the company's goal of a 50 percent reduction by 2030 well ahead of schedule;
• Processed and repurposed nearly 1.7 million end-of-life railroad track ties as the only North American wood tie manufacturer with a complete circularity solution;
• Pursued sustainable end-uses for our enhanced carbon products, including a patented process to produce a coal tar pitch with low impurity content that has the potential to serve the emerging electric vehicle (EV) and lithium-ion (Li-ion) battery markets globally; and
• Achieved record financial results in 2022, with sales of $1.98 billion.

Newsweek partnered with Statista to compile the list based on a vetting process that included research from publicly available key performance indicators and an independent survey among U.S. citizens. The initial analysis focused on a pool of 2,000 of the largest U.S.-based public companies based on revenue. The 2024 list recognized the 600 most responsible companies in the U.S. from across 14 industries.
