Ecovyst Inc. reported a strong turnaround for the three months ended March 31, 2026, with continuing-operations sales rising to $215.0 million from $143.1 million and net income from continuing operations improving to $5.7 million from a loss of $8.1 million a year earlier.
Gross profit nearly doubled to $36.4 million as higher volumes of virgin and regenerated sulfuric acid, better contract pricing and pass-through of higher sulfur costs more than offset increased manufacturing expenses. Adjusted EBITDA from continuing operations increased to $39.8 million, helped by the Waggaman, Louisiana asset acquisition and strong refining and industrial demand.
The company repurchased 3.2 million shares for about $35.7 million, ending the quarter with $162.6 million in cash and no ABL borrowings against a $397.1 million term loan. Ecovyst also disclosed a signed agreement to acquire INEOS’s Calabrian sulfur derivatives business for $190 million, aiming to expand its sulfur-based product portfolio.
Ecovyst Inc. reported significantly improved first quarter 2026 results and raised its full-year 2026 outlook. Sales from continuing operations were $215.0 million, up 50% from $143.1 million a year earlier, driven by higher sulfuric acid prices and volumes, including contribution from the Waggaman assets.
The company generated net income from continuing operations of $5.7 million, compared with a loss of $8.1 million, and Adjusted EBITDA of $39.8 million, up 87% from $21.3 million, as stronger pricing and demand more than offset higher manufacturing and transportation costs. Operating cash flow from continuing operations increased to $19.6 million from $6.7 million, and Ecovyst repurchased $35.7 million of stock in the quarter.
For 2026, Ecovyst now guides to sales of $890–$970 million and Adjusted EBITDA of $180–$195 million, both higher at the low end than prior guidance. The company expects continued strong demand for regenerated sulfuric acid and higher virgin sulfuric acid sales, while remaining cautious on some industrial applications.
