The Company's global revenue mix by product category for the year ended December 31, 2025 is laboratory (56% of sales), industrial (39% of sales), and retail (5% of sales).

The payment terms in the Company’s contracts with customers do not exceed one year and therefore contracts do not contain a significant financing component. In most cases, after appropriate credit evaluations, payments are due in arrears and are recognized as receivables. Unbilled revenue is recorded when performance obligations have been satisfied, but not yet billed to the customer. Unbilled revenue as of December 31, 2025 and 2024 was $32.3 million and $32.6 million, respectively, and is included within accounts receivable. Deferred revenue and customer prepayments are recorded when cash payments are received or due in advance of the performance obligation being satisfied. Deferred revenue primarily includes prepaid service contracts, as well as deferred installation.
Changes in the components of deferred revenue and customer prepayments during the period are as follows:
202520242023
Beginning balances as of January 1$204,166 $202,022 $192,759 
Customer prepayments/deferred revenue744,971 656,890 670,178 
Revenue recognized(727,755)(643,067)(663,165)
Foreign currency translation7,996 (11,679)2,250 
Ending balance as of December 31$229,378 $204,166 $202,022 
The Company generally expenses sales commissions when incurred because the contract period is one year or less. These costs are recorded within selling, general, and administrative expenses. The value of unsatisfied performance obligations other than customer prepayments and deferred revenue associated with contracts greater than one year is immaterial.

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.
