Corporate rebrand and NASDAQ ticker change to "ARQ" effective February 1, 2024

GREENWOOD VILLAGE, Colo., Jan. 23, 2024 (GLOBE NEWSWIRE) -- Advanced Emissions Solutions, Inc. (NASDAQ:ADES) (the "Company" or "ADES"), a producer of activated carbon and other environmentally efficient carbon products for use in purification and sustainable materials, today announced a corporate rebrand to Arq, Inc. ("Arq"), expected to be effective before market open on Thursday, February 1, 2024. This corporate rebrand follows ADES's completed acquisition of substantially all of the assets of Arq Limited and all of its subsidiaries in February 2023, which enabled the Company's expansion to becoming an environmental technology company, developing high-performing patented products that help industrial customers accelerate to a cleaner, more sustainable future.

"We are excited to mark the one-year anniversary of our transformational acquisition with a corporate rebrand that best reflects our expansion and evolution to a leading North American environmental technology company," said Bob Rasmus, Chief Executive Officer of ADES. "Today's announcement demonstrates our success in driving an efficient integration of the two platforms over the past 12-months, which delivers greater stakeholder value, diversifies our portfolio for customers and meaningfully expands our growth opportunities."

Mr. Rasmus continued, "We are more confident than ever in the value of the strategic steps we have taken to evolve ADES's legacy position as an industrial manufacturing company servicing a stable market, to adding on a technology-driven platform in a high-growth sector with sustainable, attractive economics. By adding Arq's proprietary feedstock base of bituminous coal waste to our proven operational foundation, we will turbocharge our growth and profitability, materially reduce our carbon footprint, and further solidify our leadership position in the activated carbon market. We are proud of the progress we have made to date and look forward to driving further value for all stakeholders."

"As Arq, we are committed to partnering with our customers to provide solutions that make the air we breathe, the water we drink and the soil our children play on safer and healthier," said Garrett Chandler, Arq's Vice President of Sales. "We are excited about our ability to drive growth and execution on our newly rebranded platform."
