Contract Balances
Our contracts with milestone payments have, in the aggregate, a significant impact on the contract asset and the contract liability balances. Milestones are contractually agreed with customers and relate to significant events across the contract lives. Some milestones are achieved before revenue is recognized, resulting in a contract liability, while other milestones are achieved after revenue is recognized resulting in a contract asset.
The following table provides information about contract assets and contract liabilities from contracts with customers.

Performance Obligations
As of December 31, 2025, the aggregate amount of the transaction price allocated to remaining performance obligations that were unsatisfied (or partially unsatisfied) was $396 million. In arriving at this value, we have used two expedients available to us and are not disclosing amounts in relation to performance obligations: (1) that are part of contracts with an original expected duration of one year or less; or (2) on contracts where we recognize revenue in line with the billing. Of this amount, we expect to recognize revenue of $309 million over the next 12 months, $86 million within the next 24 months, and substantially all of the remaining balance of $1.2 million within the next 36 months.
In our Manufactured Products and ADTech segments, we have long-term contracts that extend beyond one year, and these make up the majority of the performance obligations balance reported as of December 31, 2025. We also have shorter-term product contracts with an expected original duration of one year or less that have been excluded.
Where appropriate, we have made estimates within the transaction price of elements of variable consideration within the contracts and constrained those amounts to a level where we consider it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The amount of revenue recognized in the years ended December 31, 2025 and 2024 that was associated with performance obligations completed or partially completed in prior periods was not significant.
As of December 31, 2025, there were no significant outstanding liability balances for refunds or returns due to the nature of our contracts and the services and products we provide. Our warranties are limited to assurance warranties that are of a standard length and are not considered to be material rights. The majority of our contracts consist of a single performance obligation. While our contracts predominantly only contain one performance obligation and a limited number have variable consideration, when there are multiple obligations, we look for observable evidence of stand-alone selling prices on which to base the allocation. This involves judgment as to the
appropriateness of the observable evidence relating to the facts and circumstances of the contract. If we do not have observable evidence, we estimate stand-alone selling prices by taking a cost-plus-margin approach, using typical margins from the type of product or service, customer and regional geography involved.
Costs to Obtain or Fulfill a Contract
In line with the available practical expedient, we capitalize incremental costs to obtain a contract that would not have been incurred if the contract had not been obtained when those amounts are significant and the contract is expected at inception to exceed one year in duration. Our costs to obtain a contract primarily consist of bid and proposal costs, which are generally expensed in the period incurred. There were no balances or amortization of costs to obtain a contract in the current reporting periods.
Costs to fulfill a contract primarily consist of certain mobilization costs incurred to provide services or products to our customers. These costs are deferred and amortized over the period of contract performance. The closing balance of costs to fulfill a contract was $2.1 million and $3.2 million as of December 31, 2025 and 2024, respectively. For the years ended December 31, 2025, 2024 and 2023, we recorded amortization expense of $2.9 million, $4.9 million, and $5.8 million, respectively. No impairment costs were recognized.

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.
