What Is The Investigation About?

On November 5, 2025, Arq released its third quarter 2025 financial results. Among other items, Arq reported a net loss of $0.7 million, and EPS of -$0.01, missing consensus estimates. Further, the Company disclosed that Arq’s granular activated carbon (“GAC”) facility in Corbin, Kentucky operated “well below capacity, which significantly reduced [the Company’s] financial results,” due to “design issues.” Management revealed it would “now expect to reach full GAC capacity sometime around mid-2026.”

On this news, Arq’s stock price fell $2.25, or 35.4%, to close at $4.10 per share on November 6, 2025, thereby injuring investors.

Then, on March 9, 2026, Arq released its fourth quarter and full year 2025 financial results, reporting a net loss of $50 million, and an EPS of -$0.11, missing consensus estimates. Further, the Company disclosed that it had decided "to pause [its] GAC production project to conduct a comprehensive engineering and production process optimization review” and, as a result, “there will be no GAC production in 2026.” Management further described “fundamental design flaws in the plant.”

On this news, Arq’s stock price fell $1.56, or 48.8%, to close at $1.64 per share on March 10, 2026, thereby injuring investors further.
