Note 3.  Revenue from Contracts with Customers
 
The Company's revenues are primarily derived from the sale of products in product lines within our Consumer & Specialties and Engineered Solutions businesses.
 
Our primary performance obligation (the sale of products) is satisfied upon shipment or delivery to our customers based on written sales terms, which is also when control is transferred. In most of our contracts in our Specialty Additives product line, which is in our Consumer & Specialties segment, the price per ton is based upon the total number of tons sold to the customer during the year. Under these contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual volume that will be sold to such customer. Revenues are adjusted at the end of each year to reflect the actual volume sold.
 
Revenue from sales of equipment, primarily in our High-Temperature Technologies product line within our Engineered Solutions segment, is recorded upon completion of installation and control is transferred to the customer. Revenue from services is recorded when the services have been performed. Included within our High-Temperature Technologies product line are certain consignment arrangements with certain customers in our Engineered Solutions segment. Revenues for these transactions are recorded when the consigned products are consumed by the customer and control is transferred.
 
Revenue where our performance obligations are satisfied in phases is recognized over time using certain input measures based on the measurement of the value transferred to the customer, including milestones achieved.
 
The following table disaggregates our revenue by major source (product line) for the years ended December 31, 2025, 2024, and 2023:

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
