## Overview

Ecovyst Inc. is a U.S.-based industrial chemicals company built around sulfuric acid regeneration, virgin sulfuric acid, and related treatment services. Its business model is tied to long-term contracts with industrial customers, especially refineries and other process industries that rely on its products as critical inputs rather than large end-product cost items.

## Products & services

• Virgin sulfuric acid production
• Sulfuric acid regeneration services
• Acid treatment and handling services
• Industrial sulfur-based process solutions
• Catalyst-related products and services (discontinued in 2025)

- **Ecoservices** (95%) — Sulfuric acid regeneration, virgin sulfuric acid, and related treatment services sold under long-term industrial contracts.
- **Industrial sulfuric acid products** (35%) — Virgin sulfuric acid and sulfur-based products used in refining and industrial processing.
- **Regeneration and treatment services** (50%) — Collection, regeneration, and processing services that recycle spent sulfuric acid for reuse.
- **Other industrial applications** (5%) — Smaller end-use applications across mining, automotive, and other industrial markets.
- **Advanced Materials & Catalysts** (5%) — Catalyst-related products and affiliated investments that were sold and treated as discontinued operations in 2025.

- Sulfuric acid regeneration services
- Acid treatment and handling services
- Industrial sulfur-based process solutions
- Catalyst-related products and services (discontinued in 2025)

## Customers

Ecovyst sells primarily to large industrial customers, including refineries and multinational manufacturers, that use sulfuric acid and regeneration services in continuous process operations. These customers buy because Ecovyst’s products are critical to their production processes, often under multi-year contracts with pass-through pricing and volume protections. The customer base is concentrated, with the top ten customers representing a majority of sales and one customer accounting for more than 10% of revenue in 2025.

- **Refining customers** (primary) — Buy regeneration services and sulfuric acid used in refinery processes, often under take-or-pay and pass-through contracts.
- **Industrial manufacturers** (primary) — Buy virgin sulfuric acid and related services for continuous industrial processing and chemical applications.
- **Mining and automotive end markets** (secondary) — Use sulfur-based products in industrial applications where reliability and pricing stability matter.
- **Multinational process-industry customers** (secondary) — Buy across geographies and value Ecovyst’s long operating history, service reliability, and contract structure.

- Refineries buying regeneration services and sulfuric acid for process operations
- Large industrial companies needing reliable acid supply and handling
- Customers seeking pass-through pricing to reduce input-cost volatility
- Long-term contract customers valuing supply reliability and logistics network
- End users in industrial, mining, and automotive applications

## Geography

Ecovyst is primarily a U.S.-centered industrial business, with operations and manufacturing concentrated in strategically located facilities and only modest foreign-currency exposure. The company reported about 5% of sales in currencies other than the U.S. dollar, with the British pound called out as the most significant FX exposure. Its footprint matters because sulfuric acid regeneration and handling are logistics-intensive and depend on proximity to customers and industrial infrastructure.

- U.S. is the core market and reporting currency is USD
- About 5% of sales are in non-U.S. dollar currencies
- British pound is the most significant foreign exchange exposure
- Nine manufacturing facilities support regional supply and logistics
- Facility proximity matters because acid transport is costly and regulated

## Strategy

Ecovyst’s strategy is to use its installed manufacturing network, long customer relationships, and contract structure to preserve margins and generate steady free cash flow. Management is also focused on capital efficiency, debt reduction, and selective growth projects such as facility expansions and capacity optimization. The 2025 sale of Advanced Materials & Catalysts sharpened the portfolio around the core Ecoservices platform.

- **Strengthen the core Ecoservices business** (short-term) — The company’s economics are anchored in sulfuric acid regeneration and related services, which generate most sales.
- **Deploy capital efficiently and reduce debt** (short-term) — Lower leverage improves flexibility and supports consistent free cash flow generation.
- **Expand capacity where demand is durable** (medium-term) — Targeted growth projects can support sales growth without changing the core business model.

- Focus capital on core sulfuric acid regeneration and virgin acid platform
- Use long-term contracts and pass-through clauses to protect margins
- Expand capacity selectively where customer demand is visible
- Reduce leverage and improve financial flexibility after asset sale
- Maintain reliability and service quality to defend supply position

## Risks

Ecovyst’s main risks come from customer concentration, industrial operating hazards, and exposure to commodity and energy costs even though many contracts include pass-through mechanisms. The business also faces plant disruption, environmental and safety liabilities, and foreign exchange volatility, while the recent divestiture of Advanced Materials & Catalysts changes the earnings mix and increases reliance on the core services platform.

- **Customer concentration** [high] — Top ten customers represented about 61% of 2025 sales, and one customer was 12% of sales.
- **Operational and process safety disruption** [high] — Manufacturing, storage, and transport of hazardous chemicals can be interrupted by leaks, fires, weather, or equipment failure.
- **Raw material and energy volatility** [medium] — Sulfur, natural gas, labor, and freight costs can move quickly, and pass-through timing may not fully offset lag.
- **Foreign exchange exposure** [medium] — About 5% of sales are in non-U.S. dollar currencies, with the British pound the largest exposure.
- **Portfolio transition after divestiture** [medium] — The sale of Advanced Materials & Catalysts increases dependence on the Ecoservices platform.

- Customer concentration could hurt sales if a major refinery or industrial buyer leaves
- Plant outages, leaks, fires, or weather events can interrupt production and shipments
- Commodity, energy, and freight volatility can pressure margins if pass-through lags
- Environmental, health, and safety incidents can create liabilities and downtime
- FX swings can affect reported results because some sales are outside the U.S. dollar

## Accounting

Ecovyst’s accounting is shaped by revenue recognition under multi-element industrial contracts, pass-through pricing, and the treatment of seasonal demand swings in regeneration services. Investors should also watch goodwill and indefinite-lived intangible impairment testing, debt modification and extinguishment costs, and the classification of the sold Advanced Materials & Catalysts segment as discontinued operations. These items can materially affect reported margins, operating income, and comparability across periods.

- **Revenue recognition under industrial contracts** — Can shift reported revenue and gross margin between periods.
- **Seasonality in regeneration services** — Quarterly results are not directly comparable across the year.
- **Goodwill and indefinite-lived intangible impairment** — A valuation shortfall could create a non-cash impairment charge.
- **Debt modification and extinguishment costs** — Can create one-time charges that distort operating trend analysis.
- **Discontinued operations accounting** — Changes revenue and earnings comparability versus prior periods.

- Revenue recognition depends on contract terms and when performance obligations are satisfied
- Pass-through pricing and quarterly adjustments affect revenue timing and margin stability
- Regeneration services are seasonal, with higher second- and third-quarter demand
- Goodwill and indefinite-lived intangibles require annual impairment testing
- Debt refinancing or repricing can create modification and extinguishment costs
- Discontinued operations from the 2025 divestiture affect comparability
