Concentrations
We sell and market our products and services through our field sales force that works closely with our channel partners, which includes a network of distributors and resellers, in developing sales opportunities. We use a two-tiered channel model whereby we sell our products and services to our distributors, which in turn sell to resellers, which then sell to end users. Revenue derived through our channel network comprised 94%, 94% and 93% of revenue in 2025, 2024 and 2023, respectively. One of our distributors accounted for 32%, 34% and 36% of revenue in 2025, 2024 and 2023, respectively. That same distributor accounted for 27% and 29% of accounts receivable at December 31, 2025 and 2024, respectively.
Contract Balances
We generally bill our customers in advance and accounts receivable are recorded when we have the right to invoice the customer. Contract liabilities consist of deferred revenue and include customer billings and payments received in advance of performance under the contract. In 2025, 2024 and 2023, we recognized revenue of $650.0 million, $581.8 million and $502.8 million, respectively, that was included in the deferred revenue balance at the beginning of each respective period.

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.
