Arq Inc's stock plummeted 48.13% as it crossed below the 5-day SMA, following the announcement of a production halt at its GAC facility and significant financial losses.
On March 9, 2026, Arq announced a pause in operations at its Corbin, Kentucky granular activated carbon (GAC) facility, limiting annual production capacity to approximately 15 million pounds. This directly affects the company's revenue and market confidence. Additionally, Arq disclosed a $44.8 million impairment charge related to the GAC project, which raises concerns about potential investor losses and legal liabilities. The company is also engaged in litigation with the engineering consultant responsible for the plant's design, further complicating its financial outlook.
The combination of halted production and disappointing financial results has shaken investor confidence, leading to a sharp decline in stock price. With the company's 2026 financial guidance projecting revenues between $120 million and $125 million, significantly below analyst expectations, the outlook remains uncertain, impacting future growth prospects.
