PCT shares fell approximately 12.65% intraday, trading near $8.64 after closing at $9.89 in the prior session. The primary catalyst was the company’s announcement of concurrent public offerings of convertible senior notes and common stock.

Shares of ARQ plunged approximately 27.50% in premarket trading on March 10, 2026, from a prior close of $3.20 to roughly $2.32. The primary catalyst was a deeply disappointing Q4 2025 earnings report, which revealed a net loss of $50.0 million for the quarter versus a net loss of $1.3 million in Q4 2024.

Q4 2025 revenue came in strong at about 214–215 million, up mid‑30s percent year over year and a few percent above estimates, but GAAP EPS was only 0.08 versus expectations around 0.31, a roughly 70–75% miss and down from 0.13 a year earlier.

ERII shares have remained resilient, trading near $15.47 ahead of Q4 and full-year 2025 earnings scheduled for February 25, 2026. Q3 2025 results exceeded expectations, with revenue of $32 million and EPS of $0.07, despite year-over-year declines tied to project timing.
