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.
