Revenue Recognition
Our primary source of revenue is from contracts with and purchase orders from customers. In most instances, our contract with a customer is the customer’s purchase order. Upon acceptance of the purchase
order, a contract exists with a customer, as a sales agreement indicates the approval and commitment of the parties, identifies the rights of both parties, identifies the payment terms, and has commercial substance. At this point, we believe it is probable that we will collect the consideration to which we will be entitled in exchange for the goods transferred to the customer.
For certain customers, we may also enter into a sales agreement that outlines pricing considerations as well as the framework of terms and conditions that apply to future purchase orders for that customer. In these situations, our contract with the customer is both the sales agreement as well as the specific customer purchase order. As our contract with a customer is typically for a single transaction or customer purchase order, the duration of the contract is typically one year or less. As a result, we have elected to apply certain practical expedients and omit certain disclosures of remaining performance obligations for contracts that have an initial term of one year or less as permitted by GAAP.
Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied, in an amount representing the consideration the Company expects to receive in exchange for selling products to its customers. We estimate the transaction price at the inception of a contract or upon fulfilling a purchase order, including any variable consideration, and will update the estimate for changes in circumstances.
We record estimates for cash discounts, defective and slow-moving product returns, promotional rebates, core return deposits, and other discounts in the period the related product revenue is recognized (“Customer Credits”). The provision for Customer Credits is recorded as a reduction from gross sales and reserves for Customer Credits are shown as an increase in accrued customer rebates and returns. Customer Credits are estimated based on contractual provisions, historical experience, and our assessment of current market conditions. Actual Customer Credits have not differed materially from estimated amounts for each period presented. Amounts billed to customers for shipping and handling are included in net sales. Costs associated with shipping and handling are included in cost of goods sold. We have concluded that our estimates of variable consideration are not constrained according to the definition in the standard.
All of our revenue was recognized under the point-in-time approach during the years ended December 31, 2025, 2024, and 2023. Also, we do not have significant financing arrangements with our customers. Our credit terms are all less than one year. Lastly, we do not receive noncash consideration (such as materials or equipment) from our customers to facilitate the fulfillment of our contracts.
Practical Expedients and Accounting Policy Elections
We have made certain accounting policy elections and are using certain practical expedients permitted under GAAP, as follows:
Do not adjust the promised amount of consideration for the effects of a significant financing component as we expect, at contract inception, that the period between when we transfer a promised good or service to the customer and when the customer pays for that good or service will be one year or less.
Expense costs to obtain a contract as incurred when the expected period of benefit, and therefore the amortization period, is one year or less.
Exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity for a customer, including sales, use, value-added, excise, and various other taxes.
Account for shipping and handling activities that occur after the customer has obtained control of a good as a fulfillment activity rather than a separate performance obligation.
Disaggregated Revenue
For disaggregation of net sales by operating segments, refer to Note 7, "Segment Information", to the Consolidated Financial Statements.
The following table presents our disaggregated net sales by geography.
For the Year Ended December 31,
(in thousands)202520242023
Net Sales to U.S. Customers$1,966,330 $1,848,420 $1,772,092 
Net Sales to Non-U.S. Customers163,989 160,777 157,696 
Net Sales$2,130,319 $2,009,197 $1,929,788 
During the years ended December 31, 2025, and December 31, 2024, two customers each accounted for more than 10% of net sales, and in the aggregate, these two customers accounted for 40% and 39% of net sales, respectively. For the year ended December 31, 2023, three customers each accounted for more than 10% of net sales, and in the aggregate, these three customers accounted for 44% of net sales. Sales to these customers are included in the Light Duty segment.

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.
