unlevered free cash flow financial
"Unlevered free cash flow of $88.6 million, compared to $86.8 million"
Unlevered free cash flow is the cash a company generates from its core business after paying operating costs and reinvesting in the business, but before any interest or debt repayments. It shows how much cash would be available to all providers of capital—owners and lenders alike—and helps investors compare underlying business performance and value companies without the distortion of different debt levels, like judging a car’s fuel efficiency before adding cargo weight.
remaining performance obligations financial
"Remaining performance obligations, short-term $712,864 and long-term $300,340"
Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.
non-GAAP operating margin financial
"Non-GAAP operating margin was 23.6%, compared to 20.4%"
Non-GAAP operating margin is a way companies show how much profit they make from their main business activities, excluding certain expenses or income they consider unusual or non-recurring. It helps investors see how well the company is performing in its normal operations, without the effects of one-time costs or gains that might distort the picture.
stock-based compensation financial
"Includes stock-based compensation as follows ... Total stock-based compensation $43,854"
Stock-based compensation is when a company pays employees, directors or consultants with shares or the right to buy shares instead of or in addition to cash. It matters to investors because issuing stock or options spreads ownership thinner (like cutting a pie into more slices), which can reduce each existing share’s claim on profits and can also change reported earnings; investors watch it to assess true cost of running the business and how management is incentivized.
exposure management technical
"Tenable is the exposure management company, exposing and closing cybersecurity gaps"
Exposure management is the ongoing process a business or investor uses to find, measure, and control the ways losses could happen from market moves, counterparty problems, cash shortages or operational failures. It matters because it reduces the chance that an unexpected event wipes out value—like steering a ship to avoid storms—so investors can better predict potential losses, protect returns, and align risk with their goals and rules.
Magic Quadrant market
"Named a Challenger in the 2026 Gartner Magic Quadrant for CPS Protection Platforms"
A magic quadrant is a two-dimensional chart that places companies in a market into four groups based on how well they perform today and how strong their future plans look; think of it like a map that shows who is leading, who is catching up, who specializes in niches, and who has big ideas but unproven delivery. Investors use it to quickly gauge competitive position, credibility, and potential growth or risk when comparing companies in the same industry.
Revenue $262.1 million +9.6% year-over-year
GAAP net income $1.4 million vs. $22.9 million loss in Q1 2025
Non-GAAP net income $55.6 million vs. $44.3 million in Q1 2025
Non-GAAP diluted EPS $0.47 vs. $0.36 in Q1 2025
Guidance

For Q2 2026, revenue is expected at $263.0–$266.0 million with non-GAAP diluted EPS of $0.46–$0.48. For full-year 2026, revenue is projected at $1.068–$1.078 billion and non-GAAP diluted EPS at $1.90–$1.98, with forecast unlevered free cash flow of $285.0–$295.0 million.

All statements contained in this press release other than statements of historical fact, including statements regarding our future results of operations and financial position, our platform's ability to help our customer base prepare for the significant increase of threats and vulnerabilities associated with the use of artificial intelligence technologies, our ability to accelerate global market opportunities for AI Exposure Management, our business strategy, market opportunity and plans and objectives for future operations, are forward-looking statements and represent our views as of the date of this press release. The words “anticipate,” "believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “will” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of assumptions and risks and uncertainties, many of which involve factors or circumstances that are beyond our control that could affect our financial results. These risks and uncertainties are detailed in the sections titled "Risk Factors" 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 and other filings that we make from time to time with the SEC, which are available on the SEC's website at sec.gov. Moreover, we operate in a very competitive and rapidly changing environment. New risks

emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this press release may not occur and actual results could differ materially and adversely from those anticipated or implied in any forward-looking statements. Except as required by law, we are under no obligation to update these forward-looking statements subsequent to the date of this press release, or to update the reasons if actual results differ materially from those anticipated in the forward-looking statements.
Non-GAAP Financial Measures
To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use certain non-GAAP financial measures, as described below, to understand and evaluate our core operating performance. These non-GAAP financial measures, which may be different than similarly titled measures used by other companies, are presented to enhance the overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.
We believe that these non-GAAP financial measures provide useful information about our financial performance, enhance the overall understanding of our past performance and future prospects and are helpful to investors in comparing our financial results over multiple periods with other companies in our industry.
Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the financial tables accompanying this press release.
Free Cash Flow and Unlevered Free Cash Flow: We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less purchases of property and equipment and capitalized software development costs. We believe free cash flow is an important liquidity measure of the cash that is available (if any), after purchases of property and equipment and capitalized software development costs, for investment in our business and to make acquisitions. We believe that free cash flow is useful as a liquidity measure because it measures our ability to generate cash. We define unlevered free cash flow as free cash flow plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures the cash that is available to invest in our business and meet our current debt obligations and future financing needs. However, given our debt obligations, non-cancelable commitments and other contractual obligations, unlevered free cash flow does not represent residual cash flow available for discretionary expenses.
Non-GAAP Income from Operations and Non-GAAP Operating Margin: We define these non-GAAP financial measures as their respective GAAP measures, excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses, costs related to the intra-entity asset transfers resulting from the internal restructuring of legal entities, and amortization of acquired intangible assets. Acquisition-related expenses include transaction and integration expenses, as well as costs related to the intercompany transfer of acquired intellectual property. Restructuring expenses include non-ordinary course severance, employee related benefits, and other charges to reorganize business operations. We believe that the exclusion of these expenses provides for a useful comparison of our operating results to prior periods and to our peer companies, which commonly exclude restructuring expenses.
Non-GAAP Net Income and Non-GAAP Earnings Per Share: We define non-GAAP net income as GAAP net income (loss), excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses and amortization of acquired intangible assets, including the applicable tax impacts. In addition, we exclude the tax impact and related costs of intra-entity asset transfers resulting from the internal restructuring of legal entities as well as deferred income tax benefits recognized in connection with acquisitions. We use non-GAAP net income to calculate non-GAAP earnings per share.
Non-GAAP Gross Profit and Non-GAAP Gross Margin: We define non-GAAP gross profit as GAAP gross profit, excluding the effect of stock-based compensation and amortization of acquired intangible assets. Non-GAAP gross margin is defined as non-GAAP gross profit as a percentage of revenue.
Non-GAAP Sales and Marketing Expense, Non-GAAP Research and Development Expense and Non-GAAP General and Administrative Expense: We define these non-GAAP measures as their respective GAAP measures, excluding stock-based compensation, acquisition-related expenses and costs related to intra-entity asset transfers resulting from the internal restructuring of legal entities.
