Arq, Inc. (NASDAQ: ARQ)

This investigation is for anyone who acquired securities in Arq, Inc. (NASDAQ: ARQ) prior to March 9, 2026.

The Law Offices of Howard G. Smith believes that the Company and certain of its executives violated federal law. Specifically, the Law Offices of Howard G. Smith believes that the Company misled investors regarding its financial condition. More specifically, the Law Offices of Howard G. Smith believes that the Company misled investors by failing to timely inform investors of major design flaws at the Company’s granular activated carbon (“GAC”) facility in Corbin, Kentucky which cause the facility to operate well below capacity.

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, the price of the Company’s stock dropped precipitously on unusually heavy trading volume. 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, the price of the Company’s stock again dropped precipitously on unusually heavy trading volume.
