Arq Publishes its First-Ever ESG Report

Arq, Inc. (NASDAQ: ARQ) (the "Company" or "Arq"), a producer of activated carbon and other environmentally efficient carbon products, today announced the publication of its inaugural Environmental, Social, and Governance (ESG) Report. This report builds upon the Company’s previously published 2023 ESG Overview Tear Sheet and provides a comprehensive assessment of Arq’s ongoing efforts to drive positive environmental impact, employee well-being, and responsible governance.

"The release of our 2023 ESG Report further illustrates our unwavering commitment to the environmental technology sector and reflects where we are and the strides we've made in addressing key environmental and social challenges," said Bob Rasmus, CEO of Arq. "As we look ahead, we remain committed to refining our ESG practices, improving operational efficiencies, and enhancing the experience we offer our employees and stakeholders."

Key Highlights from the report include:

Environmental Impact:

• Arq has developed a proprietary process to reclaim, purify, and recycle waste coal fines, ensuring sustainability from sourcing to product impact.
