Subscription revenue is comprised primarily of go-to-market business intelligence tools that allow our customers to access our SaaS to support sales, marketing, and recruiting processes, which include data, analytics, and insights to provide accurate and comprehensive intelligence on organizations and professionals. Our customers use our platform to identify target customers and decision makers, obtain continually updated predictive lead and company scoring, monitor buying signals and other attributes of target companies, craft messages, engage via automated sales tools, and track progress through the deal cycle.
Usage-based revenue is comprised largely of email verification and facilitation of online advertisements, which are charged to our customers on a per unit basis based on their usage. We regularly observe that customers integrate our usage-based services into their internal workflows and use our services on an ongoing basis. We recognize usage-based revenue at the point in time the services are consumed by the customer, thereby satisfying our performance obligation.
Other revenue is comprised largely of implementation and professional services fees. We recognize other revenue as services are delivered.
Of the total revenue recognized in the years ended December 31, 2025, 2024, and 2023, $462.6 million, $424.9 million, and $403.1 million were included in the unearned revenue balance as of December 31, 2024, 2023, and 2022, respectively. Revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods was not material.
Contract Assets and Unearned Revenue
The Company’s standard billing terms typically require payment at the beginning of each annual, semi-annual, or quarterly period. Subscription revenue is generally recognized ratably over the contract term starting with when our service is made available to the customer. Usage-based revenue is recognized in the period services are utilized by our customers. The amount of revenue recognized reflects the consideration the Company expects to be entitled to receive in exchange for these services.
The Company records a contract asset when revenue recognized on a contract exceeds the billings to date for that contract. Unearned revenue results from cash received or amounts billed to customers in advance of revenue recognized upon the satisfaction of performance obligations. The unearned revenue balance is influenced by several factors, including seasonality, the compounding effects of renewals, invoice duration, invoice timing, dollar size, and new business timing within the quarter. The unearned revenue balance does not represent the total contract value of annual or multi-year, non-cancelable subscription agreements.
As of December 31, 2025 and 2024, the Company had contract assets of $5.2 million and $5.0 million, respectively, which are recorded within Prepaid expenses and other current assets on our Consolidated Balance Sheets. As of December 31, 2025 and 2024, the Company had unearned revenue of $477.8 million and $477.9 million, respectively.
ASC 606 requires the allocation of the transaction price to the remaining performance obligations of a contract. Transaction price allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes unearned revenue and unbilled amounts that will be recognized as revenue in future periods. Transaction price allocated to remaining performance obligations is influenced by several factors, including seasonality, the timing of renewals, and disparate contract terms. Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes unearned revenue and backlog. The Company's backlog represents installment billings for periods beyond the current billing cycle. The majority of the Company’s noncurrent remaining performance obligations will be recognized in the next 13 to 36 months.
The remaining performance obligations consisted of the following:

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.
