AECOM (NYSE:ACM), the trusted global infrastructure leader, announced today that it has been recognized as one of the 2026 World's Most Ethical Companies® by Ethisphere, a global leader in defining and advancing the standards of ethical business practices. AECOM has received this recognition six years in a row and ten times overall, demonstrating the Company's commitment to operating with ethics and integrity.

"We are honored to be named one of the World's Most Ethical Companies® for the tenth time," said Troy Rudd, AECOM's chairman and chief executive officer. "At AECOM, safety, ethics and quality guide how we work and how we serve our clients. Our 100 percent completion of our annual Code of Conduct training and our industry-leading safety metrics reflect the shared commitment of our global teams to upholding the highest standards of integrity and accountability."

AECOM's Code of Conduct outlines a robust, cross-functional ethics and compliance program focused on preventing issues from occurring, detecting them if they happen, and resolving them appropriately. The program also features global and regional ethics committees driven by Company leaders, an annual Code of Conduct training for employees, and supplemental ethics and compliance training courses for new employees and managers.

As we mark the 20th class of honorees, this group continues to raise the bar for business integrity by embedding ethics into everyday decision-making and long-term strategy. Companies with strong ethics, compliance, and governance programs are built for better long-term performance," said Erica Salmon Byrne, Ethisphere's Chief Strategy Officer and Executive Chair.
