Here are 1-2 brief analogies to describe Ecovyst (ECVT):

• The Intel Inside for industrial processes, supplying the critical catalysts that enable plastic manufacturing and natural gas purification.
• Like Corning, but providing specialized catalysts and materials for industries ranging from plastics production to environmental purification.

• Sulfuric Acid Regeneration Services: Regenerates spent sulfuric acid for petroleum refiners and other industries, enabling its reuse.
• Virgin Sulfuric Acid: Manufactures and supplies high-purity sulfuric acid for various industrial applications.
• Polyolefin Catalysts: Provides specialized catalysts essential for the production of polyethylene and polypropylene plastics.
• Emission Control Catalysts: Develops catalysts used to reduce harmful emissions from industrial processes and diesel engines.
• Silica-based Materials: Offers advanced silica products used as catalyst supports, chromatography media, and adsorbents in diverse industries.

Ecovyst (ECVT) primarily sells its products and services to other companies (B2B model), rather than directly to individuals.

According to Ecovyst's public filings, including its most recent 10-K report for the fiscal year ended December 31, 2023, no single customer accounted for more than 10% of its consolidated net revenue for the years ended December 31, 2023, 2022, and 2021. Therefore, specific "major customers" by name are not individually disclosed as substantial revenue contributors requiring identification. Instead, Ecovyst serves a diverse customer base across various industries globally.

The primary categories of customer companies that Ecovyst serves include:

• Refining Companies: These customers utilize Ecovyst's sulfuric acid regeneration services and various catalysts in their petroleum refining processes, particularly for alkylation units.
• Petrochemical Companies: Customers in the petrochemical industry use Ecovyst's catalysts for the production of a wide range of basic chemicals and intermediates.
• Chemical Manufacturers: This broad category includes companies producing specialty chemicals and other industrial chemicals that rely on Ecovyst's catalysts and chemical products.
• Companies in the Emissions Control Sector: Ecovyst supplies catalysts used in systems designed to reduce emissions from automotive, industrial, and other sources.

Paul Whittleston has an extensive international career in the chemical industry. His prior experience includes leadership positions with companies such as Allied Colloids, CIBA Specialty Chemicals, BASF Corporation, TI Fluid Systems, and SI Group.

The accelerating global energy transition, characterized by the rapid adoption of electric vehicles and increasing regulatory and consumer shifts away from fossil fuels, poses a significant emerging threat to Ecovyst's core business segments reliant on traditional petroleum refining. This trend is expected to lead to a long-term decline in demand for gasoline and diesel, directly impacting the market for Ecovyst's Fluid Catalytic Cracking (FCC) and hydrocracking catalysts.

Ecovyst (ECVT) operates primarily in two business segments: Ecoservices and Advanced Materials & Catalysts. The Advanced Materials & Catalysts segment, however, is being sold to Technip Energies, with the transaction anticipated to close in the first quarter of 2026.

Ecoservices

Ecoservices provides sulfuric acid recycling to the North American refining industry and supplies virgin sulfuric acid for applications in water treatment, mining, and other industrial uses. Information regarding the specific addressable market size for sulfuric acid recycling services to the North American refining industry or the market for virgin sulfuric acid in water treatment, mining, and general industrial applications is not available in the provided search results.
