Calabrian

Wayne, Pa. – November 05, 2026 -- Ecovyst Inc. (NYSE: ECVT) reported third-quarter 2026 sales from continuing operations of $308.6 million, up 51% from $204.9 million a year earlier, and raised its full-year Adjusted EBITDA guidance to $208 million-$212 million from $195 million-$207 million.

Calabrian acquisition and sulfur pass-through drive the revenue increase

Sales rose $103.7 million year over year. Higher volumes and pricing contributed, as did the Calabrian sulfur dioxide business acquired on June 30, 2026. Average selling prices climbed mainly because of roughly $67 million in pass-through of higher sulfur costs and favorable contractual pricing for regenerated sulfuric acid. Regenerated sulfuric acid volumes grew on strong demand and less customer downtime.
