Due to the terms of certain contractual arrangements, Wesco bills or receives payment from its customers in advance of satisfying the respective performance obligation. Such advance billings or payments are recorded as deferred revenue and recognized as revenue when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Revenue associated with these arrangements is generally recognized within a year or less from the date of the advance billing or payment receipt. At December 31, 2025 and 2024, $151.4 million and $141.8 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Consolidated Balance Sheets. The Company recognized $102.0 million, $76.9 million and $74.0 million of revenue during the years ended December 31, 2025, 2024 and 2023 respectively, that was included in the deferred revenue balances of $141.8 million, $111.9 million and $99.6 million as of December 31, 2024, 2023 and 2022 respectively.
Wesco’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns and discounts. Wesco measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data, as well as current and forecasted information. Variable consideration is reviewed by management on a monthly basis and revenue is adjusted as necessary. Variable consideration reduced revenue for the years ended December 31, 2025, 2024 and 2023 by approximately $452.4 million, $436.2 million and $427.8 million, respectively. As of December 31, 2025 and 2024, the Company’s estimated product return obligation was $33.7 million and $41.0 million, respectively.
Billings to customers for shipping and handling are recognized in net sales. Wesco has elected to recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, general and administrative expenses totaled $335.4 million, $303.3 million and $306.8 million for the years ended December 31, 2025, 2024 and 2023, respectively.

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.
