Ecovyst Inc.

What they do

Ecovyst produces and regenerates sulfuric acid and provides related services, including regenerated sulfuric acid for alkylation in refineries, virgin sulfuric acid for mining and industrial use, and sulfur dioxide and derivatives. The company completed the sale of its Advanced Materials & Catalysts business (including the Zeolyst joint venture) to Technip Energies on December 31, 2025, and now operates as a pure-play sulfuric acid and sulfur-based products business.

Revenue drivers

• Regenerated sulfuric acid — Core service for refinery alkylation; demand tied to refinery utilization and alkylate economics. In Q2 2026, volumes increased on high refinery utilization and positive alkylate economics.
• Virgin sulfuric acid — Used in mining, industrial, and chemical applications. Q2 2026 volumes grew double digits, helped by the Waggaman plant acquired in May 2025 and positive demand fundamentals.
• Sulfur dioxide and derivatives — Acquired from INEOS Enterprises on June 30, 2026; expands presence in mining, water treatment, and adjacent applications like food processing and pharmaceuticals. Expected to contribute in second half of 2026.

Recent performance

For Q2 2026, sales grew 42% year-over-year to $250.0 million (from $176.1 million), driven by higher volume and pricing, including a ~$55 million pass-through of higher sulfur costs. Net income was $10.7 million (margin 4.3%), versus $5.0 million a year earlier. Adjusted EBITDA rose 27% to $53.1 million. Six-month cash flow from operations was $55.2 million, up from $25.3 million. Full-year 2025 revenue (continuing operations) was $723.5 million; net loss was $71.1 million, largely reflecting discontinued operations.

Strategy

Management focuses on growing sales in attractive end-use segments, maintaining high margins, and pursuing synergistic acquisitions to expand sulfur-based solutions. The company completed the Calabrian acquisition in June 2026 to broaden its platform and expects to realize meaningful synergies from integration. It also prioritizes efficient capital deployment and generating consistent free cash flow, while leveraging its nine-facility network for competitive advantage.

Risks

• Economic cyclicality — Demand for sulfuric acid is tied to refinery utilization, mining activity, and industrial production, which can decline during economic downturns.
• Raw material cost pass-through — Sulfur and natural gas price fluctuations impact costs; inability to pass through increases could compress margins.
• Customer concentration — A limited number of customers account for a meaningful portion of revenue; loss of any could materially affect results.
• Integration risk — The Calabrian acquisition may not achieve expected synergies or be integrated successfully, which could harm financial results.

Outlook

Management raised full-year 2026 Adjusted EBITDA guidance to a range of $195 million to $207 million, reflecting strong first-half performance and the anticipated contribution of Calabrian in the second half. They expect continued demand for regenerated and virgin sulfuric acid, with high refinery utilization and positive alkylate economics supporting volumes. The company believes it has adequate liquidity to fund working capital, capex, and debt service for at least the next twelve months.
