Integral to U. S. Steel's ethical culture are its S.T.E.E.L. Principles, an extension of what is widely believed to be the first-ever corporate code of ethics developed more than a century ago by company co-founder Judge Elbert Gary.

"Our S.T.E.E.L. Principles are foundational to the unequivocal ethics we display in our daily business activities and across our organization at every level," said President and Chief Executive Officer of U. S. Steel, David B. Burritt. "That Ethisphere has once again recognized U. S. Steel as one of the World's Most Ethical Companies® reinforces our reputation as a corporation dedicated to promoting a strong ethical culture that builds value for everyone."

Today, as throughout its storied history, U. S. Steel is guided by the integrity, fairness, and accountability prescribed by those principles, and is dedicated to incorporating them in every facet of its business with employees, business partners, investors, and communities.

"As U.S. Steel's Chief Ethics & Compliance Officer, it is my profound honor to acknowledge our recognition as one of Ethisphere's 2025 World's Most Ethical Companies®. This accolade is a testament to how our values and S.T.E.E.L. Principles guide our employees' actions across all our facilities and from one generation to the next," said Duane Holloway, Senior Vice President, General Counsel, and Chief Ethics & Compliance Officer of U. S. Steel.

Victoria McKenney, Deputy General Counsel & Deputy Chief Compliance Officer, adds, "Earning our fourth consecutive designation as a World's Most Ethical Companies Honoree® demonstrates our commitment to continuously improving our leading ethics and compliance program as the bar for excellence keeps being raised, and validates the positive impact we are creating for our stakeholders year after year."

Since 2022, U. S. Steel has been recognized four times, and in 2025, is the only honoree in the Metals, Minerals & Mining industry.

"Congratulations to U. S. Steel for achieving recognition as one of the World's Most Ethical Companies®. Behind this honor is a true dedication and a commitment to advancing business integrity. This approach is good for business – employees and other stakeholders value companies that prioritize the kinds of practices we measure with our process," said Erica Salmon Byrne, Ethisphere's Chief Strategy Officer and Executive Chair.

Ethics & Performance: The Ethics Premium

The listed 2025 World's Most Ethical Companies® Honorees outperformed a comparable index of global companies by 7.8 percentage points from January 2020 to January 2025.

Methodology & Scoring

The World's Most Ethical Companies assessment is grounded in Ethisphere's proprietary Ethics Quotient®, which requires companies to provide 240+ different proof points on practices that support robust ethics and compliance; governance; a culture of ethics; environmental and social impact; and initiatives that support a strong value chain. That data undergoes further qualitative analysis by our panel of experts who spend thousands of hours vetting and evaluating each year's group of applicants. This process serves as an operating framework to capture and codify best-in-class ethics and compliance practices from organizations across industries and from around the world.
