Forward Looking Statements This presentation includes forward-looking statements. All statements contained in this presentation other than statements of historical fact, including statements regarding our future results of operations and financial position, business strategy and plans and our objectives for future operations, are forward-looking statements. 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. 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. 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. This presentation contains projected financial information. Such projected financial information constitutes forward-looking information and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive, and other risks and uncertainties as described above. Actual results may differ materially from the results contemplated by the financial forecast information contained herein, and the inclusion of such information in this presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. Except as required by law, we are under no obligation to update these forward-looking statements after the date of this presentation to conform these statements to actual results or revised expectations. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this presentation. This presentation also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. We make no representation or warranty as to the accuracy or completeness of such data and undertake no obligation to update such data after the date of this presentation. In addition, projections, assumptions and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk. By receiving this presentation you acknowledge that you will be solely responsible for your own assessment of the market and our market position and that you will conduct your own analysis and be solely responsible for forming your own view of the potential future performance of our business. This presentation includes non-GAAP financial measures which have certain limitations and should not be considered in isolation, or as alternatives to or substitutes for, financial measures determined in accordance with GAAP. The non-GAAP measures as defined by us may not be comparable to similar non-GAAP measures presented by other companies. Our presentation of such measures, which may include adjustments to exclude unusual or non-recurring items, should not be construed as an inference that our future results will be unaffected by these or other unusual or non-recurring items. See the GAAP to Non-GAAP Reconciliation section for a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures. Any information in this presentation on unreleased services or features is intended to outline our general product direction and should not be relied upon in making a purchasing decision. They are intended for informational purposes only and may not be incorporated into any contract. The development, release, and timing of any features or functionality described for our products remains at our sole discretion. All third-party trademarks, including names, logos and brands, referenced by us in this presentation are property of their respective owners. These references are made solely for identification purposes and should not be construed as an endorsement of our products or services.

Tenable evolution

![](tenbinvestorday052126006.jpg)

● AI accelerates software development and deployment ● Every new AI system embedded is a new entry point ● Attack surface expanding faster than teams can track ● Frontier models find vulnerabilities in minutes, not months ● Attackers gain the same capability simultaneously ● Discovery that was impossible yesterday is trivial today More exposures being created More exposures being discovered Both forces are operating at once across a larger, more interconnected attack surface than ever before.

771 > 1.6 Days to exploit Average time from disclosure to active exploitation - 2021 vs. today 500+ Zero-days found by Opus 4.6 Discovered autonomously in open- source code Thousands Vulnerabilities found by Mythos Discovered in weeks following the April 2026 launch of Mythos Preview 99% Remain unpatched Vendor disclosure processes were not built for AI-scale discovery volumes

9 When volume becomes infinite More findings. More noise. Less clarity. 60% of breaches last year exploited a vulnerability the organization already had a patch for. The problem is not finding what's wrong. It's acting on it fast enough.

Vulnerability Discovery "What code vulnerabilities exist in a piece of code" 1. Asset Discovery "What is in your enterprise?" Discovery Alone Does Not Reduce Risk 4. Remediation "Help me fix it" 2. Assessment "What issues exist in your org?" 3. Prioritization "What issues actually matter?" 5. Validation "Did it actually get fixed?" Exposure ManagementLatest Frontier Models

Appendix Non-GAAP Financial Measures Non-GAAP Income from Operations and Non-GAAP Operating Margin Non-GAAP income from operations and non-GAAP operating margin are defined as GAAP income from operations and GAAP operating margin, excluding stock-based compensation expense, 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. Unlevered Free Cash Flow Unlevered free cash flow is defined as net cash provided by operating activities less purchases of property and equipment and capitalized software development costs, plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures our ability to generate 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.
