Contract Balances

 

The timing of revenue recognition and billings can result in unbilled receivables (contract assets). The Company’s contract liabilities consist of deferred revenues which represent advance payment from customers in advance of the completion of the Company’s performance obligation. The following table represents changes in our contract asset and contract liabilities balances for the periods noted:

 

           Year-to-date   Year-to-date 
(In thousands)  December 31, 2025   December 31, 2024   Change ($)   Change (%) 
Contract assets                    
Unbilled receivables - current  $8,781   $4,990   $3,791    76.0%
                     
Contract liabilities                    
Deferred revenue  $7,007   $6,711   $296    4.4%

 

The increase in unbilled receivables from 2024 to 2025 was primarily due to timing difference between completion of revenue recognition and agreed upon invoicing terms at one of our Treatment facilities.

 

           Year-to-date   Year-to-date 
(In thousands)  December 31, 2024   December 31, 2023   Change ($)   Change (%) 
Contract assets                    
Unbilled receivables - current  $4,990   $8,432   $(3,442)   (40.8)%
                     
Contract liabilities                    
Deferred revenue  $6,711   $6,815   $(104)   (1.5)%

 

The reduction in unbilled receivables from 2023 to 2024 was primarily due to invoicing in 2024 of two large Services Segment projects that were primarily completed by the end of 2023.

 

During the twelve months ended December 31, 2025, and 2024, the Company recognized revenue of $5,365,000 and $5,887,000, respectively, related to untreated waste that was in the Company’s control as of the beginning of each respective year. Revenue recognized in each period relates to performance obligations satisfied within the respective period.
