Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

21. Revenue from Contracts with Customers

The Company deems a contract with a customer to exist when a purchase order is received from a customer for a specified quantity of product or products and the Company acknowledges receipt of such purchase order. In some instances, the Company has entered into manufacturing supply agreements with customers but these agreements typically do not bind a customer to any purchase volume requirements and thus an obligation is not created until the customer submits a purchase order to the Company. The Company’s contracts typically have a single performance obligation that is satisfied at the time product is shipped and control passes to the customer. For a small portion of the business, performance obligations are deemed satisfied when product is delivered to a customer location.

As of December 31, 2025, the Company had $218,000 of contract liabilities and no contract assets. A contract liability would typically arise when an advance or deposit is received from a customer before the Company recognizes revenue. In practice, this is rare

as it would require a customer to make a payment prior to a performance obligation being satisfied. When such situations do arise, the Company maintains a deferred revenue liability until the time a performance obligation has been satisfied. The Company recognized $689,000 of revenue in 2025 from pre-existing contract liabilities at December 31, 2024.

In addition, during 2020 the Company recorded $10,709,000 of long-term deferred revenue associated with a payment received to defray the cost of capital expenditures necessary to service a customer’s future product needs. On December 31, 2025, $2,216,000 was classified as long-term and $2,216,000 was classified as short-term. This deferred revenue will be recognized over the period of the contract and $6,277,000 of revenue has been recognized from the beginning of the contract term through December 31, 2025.
