Wabash National Corporation Achieves Certification to the New ISO 14001:2015 Standard for Environmental Management

LAFAYETTE, Ind. - December 18, 2018 -Wabash National Corporation (NYSE: WNC), a diversified industrial manufacturer and a leading producer of semi-trailers, truck bodies and liquid transportation systems, has received certification to the new ISO 14001:2015 standard from the prior ISO 14001:2004 standard at five manufacturing operations.

The ISO 14001:2015 standard provides organizations with the elements of an effective environmental management system that can be integrated with other management requirements to help them achieve environmental and economic goals. The overall aim of this International Standard is to support environmental protection and prevention of pollution in balance with socio-economic needs.

'Our commitment to sustainability is evident at every level of our company, and we continue to make significant strides in reducing our impact on the environment,' said Andrew Frisbie, director, corporate EH&S. 'Achieving the new standard across multiple facilities reflects our promise to upholding world-class environmental standards in our manufacturing operations. I am proud of the entire team for their commitment to our ongoing environmental initiatives.'

Wabash National was the first semi-trailer manufacturer in North America to receive the Environmental Management System Registration in June 2005. New ISO standards are released approximately every 10 years with new requirements, including being expected to show an increased alignment of environmental management within an overall strategic planning process, a greater commitment from leadership and lifecycle thinking.

The company has earned the new ISO 14001:2015 standard at its operations in Lafayette, Indiana; Cadiz, Kentucky; Harrison, Arkansas; Portland, Oregon; and San Jose Iturbide, Guanajuato, Mexico.
