Computed values are grepcent-computed from the verified facts above and may differ from ratios the company itself reports. Free cash flow = operating cash flow − capital expenditures. Net margin = net income ÷ revenue. Operating margin = operating income ÷ revenue. Revenue YoY = FY2025 revenue ÷ FY2024 revenue − 1 (consecutive fiscal years only). ROE = net income ÷ period-end stockholders' equity.

Item 2.        Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with (1) our consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q, or this Form 10-Q, and (2) our consolidated financial statements, related notes and management's discussion and analysis of financial condition and results of operations in our Annual Report on Form 10-K for the year ended December 31, 2025, or the 10-K, filed with the Securities and Exchange Commission, or the SEC, on February 27, 2026. This Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. These statements are often identified by the use of words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “will,” “would” or the negative or plural of these words or similar expressions or variations. Such forward-looking statements are subject to a number of risks, uncertainties, assumptions and other factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified herein, and those discussed in the section titled “Risk Factors,” set forth in Part I, Item 1A of the 10-K, in Part II, Item 1A of this Form 10-Q and in our other filings with the SEC. You should not rely upon forward-looking statements as predictions of future events. Furthermore, such forward-looking statements speak only as of the date of this report. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Overview

We are the leading provider of exposure management solutions. Exposure management is an increasingly critical category that extends foundational vulnerability management, capabilities to advance risk assessment and prioritization across the entire attack surface – from IT infrastructure and cloud environments to critical infrastructure and AI. We unify security visibility, insight and action across this attack surface, equipping modern organizations to quickly identify and close the cybersecurity gaps that erode business value, reputation and trust.

Tenable One, our AI-powered exposure management platform, gives enterprises a single, unified view of risk across all types of assets and attack pathways. The platform combines broad, industry-leading vulnerability coverage, spanning IT assets, cloud resources, containers, web apps, identity systems, third-party connectors and AI-related assets and workloads.

Our solutions are primarily sold on a subscription basis with a one-year term, but are increasingly being sold with longer contractual durations. Our subscription terms are generally not longer than three years. These subscriptions are typically invoiced in advance at the beginning of the term, however multi-year subscriptions are increasingly being invoiced annually in installments.

We sell and market our products and services through our field sales force that works closely with our channel network of distributors, resellers and managed security service providers (MSSPs), in developing sales opportunities. We typically use a two-tiered channel model whereby we sell our enterprise platform offerings to our distributors, who in turn sell to our resellers, who then sell to end users, who we call customers.

Recurring revenue, which includes revenue from subscription arrangements for software (both recognized ratably over the subscription term and upon delivery) and cloud-based solutions and maintenance associated with perpetual licenses, represented 95% of revenue in the three months ended June 30, 2026 and 96% of revenue in the three months ended June 30, 2025 and the six months ended June 30, 2026 and 2025.

Operating and Financial Metrics

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use and monitor the following operating and financial metrics, which include non-GAAP financial measures, to understand and evaluate our core operating and financial performance.

Customer Metrics

We believe that our customer base provides a significant opportunity to expand sales of our enterprise platform offerings. We define an enterprise platform customer as a customer that has licensed Tenable One, Tenable Vulnerability Management, Tenable Cloud Security, Tenable Identity Exposure, Tenable OT Security or Tenable Security Center for an annual amount of $5,000 or greater. New enterprise platform customers represent new customer logos during the periods presented and do not include customer conversions from Tenable Nessus Expert to enterprise platforms. The following tables summarize key components of our customer base:

Dollar-Based Net Expansion Rate

Our dollar-based net expansion rate reflects both our customer retention and ability to drive additional sales to our existing customers. Our dollar-based net expansion rate has historically fluctuated and is expected to continue to fluctuate on a quarterly basis as a result of a number of factors, including existing customers' satisfaction with our solutions, existing customer retention, the pricing of our solutions, the availability of competing solutions and the pricing thereof, and the timing of customer renewals. In addition, our sales pipeline opportunities vary from quarter to quarter between new customers and expansion from existing customers, and we do not prioritize one over the other to maximize the dollar-based net expansion rate.

Our dollar-based net expansion rate is evaluated on a last twelve months, or LTM, basis, and is calculated as follows:

19

Table of Contents

•Denominator: To calculate our dollar-based net expansion rate as of the end of a reporting period, we first determine the annual recurring revenue, or ARR, from all active subscriptions (both revenue recognized ratably over the subscription term and upon delivery) and maintenance from perpetual licenses as of the last day of the same reporting period in the prior year. This represents recurring payments that we expect to receive in the next 12-month period from the cohort of customers that existed on the last day of the same reporting period in the prior year.

•Numerator: We measure the ARR for that same cohort of customers representing all subscriptions and maintenance from perpetual licenses based on customer orders as of the end of the reporting period.

We calculate dollar-based net expansion rate by dividing the numerator by the denominator.

The following table presents our dollar-based net expansion rate:

Components of Our Results of Operations

Revenue

We generate revenue from subscription arrangements for our software and cloud-based solutions, perpetual licenses, maintenance associated with perpetual licenses and professional services.

We typically experience seasonality in customer agreement volumes, entering into a significantly higher percentage of new and renewal agreements in the third and fourth quarters of the year. The increase in the third quarter is primarily driven by U.S. government and related agencies, and the increase in the fourth quarter reflects typical large enterprise buying patterns in the software industry. Although the ratable nature of our subscription revenue lessens the financial impact, these historical trends may be impacted by macroeconomic conditions and U.S. policy decisions, which may lengthen purchasing and approval phases of our sales cycle.

Cost of Revenue, Gross Profit and Gross Margin

Cost of revenue includes personnel costs related to our technical support group that provides assistance to customers, including salaries, benefits, bonuses, payroll taxes, stock-based compensation and any ordinary course severance. Cost of revenue also includes cloud infrastructure costs, the costs related to professional services and training, depreciation, amortization of acquired and developed technology, hardware costs and allocated overhead costs, which consist of information technology, facilities and insurance.

We expect our gross profit, or revenue less cost of revenue, to increase in absolute dollars but our gross margin, or gross profit as a percentage of revenue, may fluctuate from period to period, particularly as it relates to cloud infrastructure costs, as we expect revenue from our cloud-based subscriptions to increase as a percentage of revenue.

Operating Expenses

Our operating expenses consist of sales and marketing, research and development, general and administrative and restructuring expenses. Personnel costs are the most significant component of operating expenses and consist of salaries, benefits, bonuses, payroll taxes, stock-based compensation and ordinary course severance. Operating expenses also include depreciation and amortization, allocated overhead costs, including IT and facilities costs, as well as acquisition-related expenses.

Sales and marketing expense consists of personnel costs, sales commissions, marketing programs, travel and entertainment, expenses for conferences, meetings and events, allocated overhead costs and acquisition-related expenses.

Table of Contents

Research and development expense consists of personnel costs, software used to develop our products, travel and entertainment, consulting and professional fees for third-party development resources, allocated overhead and acquisition-related expenses. Our research and development expense supports our efforts to continue to add capabilities to our existing products and enable the continued detection of new network vulnerabilities.

General and administrative expense consists of personnel costs for our executive, finance, legal, human resources and administrative departments. Additional expenses include travel and entertainment, professional fees, insurance, allocated overhead and acquisition-related expenses.

Restructuring expenses consist of non-ordinary course severance, employee related benefits and other charges to reorgan

Our subscription terms are generally not longer than three years. These subscriptions are typically invoiced in advance at the beginning of the term, however multi-year subscriptions are increasingly being invoiced annually in installments.

We sell and market our products and services through our field sales force that works closely with our channel network of distributors, resellers and managed security service providers (MSSPs), in developing sales opportunities. We typically use a two-tiered channel model whereby we sell our enterprise platform offerings to our distributors, who in turn sell to our resellers, who then sell to end users, who we call customers.

Recurring revenue, which includes revenue from subscription arrangements for software (both recognized ratably over the subscription term and upon delivery) and cloud-based solutions and maintenance associated with perpetual licenses, represented 96% of revenue in 2025 and 2024 and 95% of revenue in 2023.

Operating and Financial Metrics

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use and monitor the following operating and financial metrics, which include non-GAAP financial measures, to understand and evaluate our core operating and financial performance.

Calculated Current Billings

Calculated current billings consists of revenue recognized in a period plus the change in current deferred revenue in the corresponding period. Variability in total billings, depending on the timing of large multi-year contracts and the preference for annual billing versus multi-year upfront billing, may distort growth in one period over another.

Calculated current billings may vary from period-to-period for a number of reasons, and therefore has a number of limitations as a quarter-to-quarter or year-over-year comparative measure. Calculated current billings in any one period may be impacted by the timing and amount of new sales transactions, the timing and amount of renewal transactions, including early renewals, the mix of the amount of subscriptions and perpetual licenses and the timing of billing professional services, as well as the timing and amount of multi-year prepaid contracts, all of which could favorably or unfavorably impact quarter-to-quarter and year-over-year comparisons. For example, an increasing number of large sales transactions, for which the timing has and will continue to vary, may occur in quarters subsequent to or in advance of those that we anticipate. Additionally, our calculation of calculated current billings may be different from other companies that report similar financial measures. Because of these and other limitations, you should consider calculated current billings along with revenue and our other GAAP financial results.

Historically we have used calculated current billings as a key metric to measure our periodic performance and to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers. Recently, however, the shift to annual installment billing for larger multi-year transactions is reducing our overall billing duration. We believe this shift creates a negative distortion in calculated current billings that fails to accurately represent the growth of our business and as such we have transitioned away from relying on calculated current billings to monitor performance of our business. We have included calculated current billings for comparative purposes.

The following table presents calculated current billings, including a reconciliation of revenue, the most directly comparable financial measure calculated in accordance with GAAP:

Customer Metrics

We believe that our customer base provides a significant opportunity to expand sales of our enterprise platform offerings. We define an enterprise platform customer as a customer that has licensed Tenable One, Tenable Vulnerability Management, Tenable Cloud Security, Tenable Identity Exposure, Tenable OT Security or Tenable Security Center for an annual amount of $5,000 or greater. New enterprise platform customers represent new customer logos during the periods presented and do not include customer conversions from Tenable Nessus Expert to enterprise platforms. The following tables summarize key components of our customer base:

Dollar-Based Net Expansion Rate

Our dollar-based net expansion rate reflects both our customer retention and ability to drive additional sales to our existing customers. Our dollar-based net expansion rate has historically fluctuated and is expected to continue to fluctuate on a quarterly basis as a result of a number of factors, including existing customers' satisfaction with our solutions, existing customer retention, the pricing of our solutions, the availability of competing solutions and the pricing thereof, and the timing of customer renewals. In addition, our sales pipeline opportunities vary from quarter to quarter between new customers and expansion from existing customers, and we do not prioritize one over the other to maximize the dollar-based net expansion rate.

Our dollar-based net expansion rate is evaluated on a last twelve months, or LTM, basis, and is calculated as follows:

•Denominator: To calculate our dollar-based net expansion rate as of the end of a reporting period, we first determine the annual recurring revenue, or ARR, from all active subscriptions (both revenue recognized ratably over the subscription term and upon delivery) and maintenance from perpetual licenses as of the last day of the same reporting period in the prior year. This represents recurring payments that we expect to receive in the next 12-month period from the cohort of customers that existed on the last day of the same reporting period in the prior year.

•Numerator: We measure the ARR for that same cohort of customers representing all subscriptions and maintenance from perpetual licenses based on customer orders as of the end of the reporting period.

We calculate dollar-based net expansion rate by dividing the numerator by the denominator.

The following table presents our dollar-based net expansion rate:

Components of Our Results of Operations

Revenue

We generate revenue from subscription arrangements for our software and cloud-based solutions, perpetual licenses, maintenance associated with perpetual licenses and professional services. We begin to recognize revenue when control of our software or services is transferred to the customer, which for sales made through our channel network is typically concurrent with the transfer to the end user.

Our subscription arrangements generally have annual or multi-year contractual terms to use our software or cloud-based solutions, including ongoing software updates during the contractual period. For software subscriptions that are dependent on ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities, revenue is
