In its own words
What could break it.
Customer concentration
- largest customer (~12% of sales)medium
Ecovyst's top ten customers represented ~61% of 2025 sales; one customer (unnamed 'Customer A') individually exceeded 10%, representing approximately 12% (~$89 million) of total sales (12.3%/14.0%/13.2% across 2025/2024/2023). Loss of this customer would be material.
“our top ten customers in 2025 representing approximately 61% of our sales for the year ended December 31, 2025, of which one customer had more than 10% of our total sales. This customer represented 12% or $89 million of our sales during this period.”

Geographic concentration
- Gulf Coast and California refining-region facilitiesmedium
Ecovyst's manufacturing network is concentrated in the U.S. Gulf Coast and California — regions where ~64% of U.S. refining capacity is located — tying its sulfuric-acid regeneration and virgin acid business to those refining hubs and exposing it to region-specific disruptions.
“Our network of facilities is concentrated in the Gulf Coast and the state of California, where approximately 64% of the United States refining capacity is located.”
