Arq shares rise 10.37% premarket as CEO Rasmus buys $189,590 in stock.

Arq Inc. surged 10.37% in premarket trading following a significant stock purchase by CEO Robert Rasmus, who acquired 50,000 shares for $189,590. The transaction, reported via SEC filings and analyzed on X, is interpreted as a confidence-boosting signal amid recent volatility. While the company’s third-quarter earnings missed expectations (EPS -$0.02 vs. $0.02) and revenue underperformed, the CEO’s aggressive buying contrasts with broader insider selling and aligns with a "Buy" rating from Canaccord Genuity. The move suggests management’s optimism about Arq’s near-term prospects despite operational challenges in scaling its GAC production, anchoring investor sentiment in premarket activity.
