1 Q2 FY2027 Earnings Presentation August 27, 2026

2SentinelOne® Safe Harbor This presentation includes express and implied “forward-looking statements”, including forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that are not historical facts, and in some cases, can be identified by terms such as “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “should,” “will,” “would,” or the negative of these terms, and similar expressions that concern our expectations, strategy, plans or intentions. Forward-looking statements contained in this presentation include, but are not limited to, statements concerning our estimates of market size and opportunity, our strategic plans or objectives, our growth prospects, projections (including our long-term model), actual or perceived defects, errors or vulnerabilities in our platform; our ability to successfully integrate any acquisitions and strategic investments; risks associated with managing our rapid growth; general global political, economic, and macroeconomic climate, intense competition in the market we compete in, fluctuations in our operating results, our ability to attract new and retain existing customers, or renew and expand our relationships with them; the ability of our platform to effectively interoperate within our customers’ IT infrastructure; disruptions or other business interruptions that affect the availability of our platform including cybersecurity incidents; the failure to timely develop and achieve market acceptance of new products and subscriptions as well as existing products, subscriptions and support offerings; rapidly evolving technological developments in the market for security products and subscription and support offerings; length of sales cycles; and risks of securities class action litigation. By their nature, these statements are subject to numerous risks and uncertainties, including factors beyond our control, that could cause actual results, performance or achievement to differ materially and adversely from those anticipated or implied in the statements. Such risks and uncertainties are described in the “Risk Factors” of our most recent Form 10-K, most recent Form 10-Q, and subsequent filings with the Securities and Exchange Commission. Although our management believes that the expectations reflected in our statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances described in the forward-looking statements will be achieved or occur. Recipients are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date such statements are made and should not be construed as statements of fact. Except to the extent required by federal securities laws, we undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date hereof, or to reflect the occurrence of unanticipated events. Certain information contained in this presentation and statements made orally during this presentation relate to or are based on studies, publications, surveys and other data obtained from third-party sources and SentinelOne’s own internal estimates and research. While SentinelOne believes these third-party studies, publications, surveys and other data to be reliable as of the date of this presentation, it has not independently verified, and makes no representations as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party sources. In addition, no independent source has evaluated the reasonableness or accuracy of SentinelOne’s internal estimates or research and no reliance should be made on any information or statements made in this presentation relating to or based on such internal estimates and research.

3SentinelOne® Financial Information Use of Non-GAAP Financial Measures In addition to our results determined in accordance with U.S. generally accepted accounting principles (“GAAP”), we believe non-GAAP measures used in this presentation, such as non-GAAP Gross Margin, non-GAAP Operating Margin, non-GAAP Net Income Margin, Free Cash Flow Margin, and Adjusted Free Cash Flow Margin are useful in evaluating our operating performance. We use such non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. In addition, the utility of Free Cash Flow Margin and Adjusted Free Cash Flow Margin as a measure of our liquidity are limited as it does not represent the total increase or decrease in our cash balance for a given period. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business. Please see the appendix included at the end of this presentation for a discussion of non-GAAP financial measures and a reconciliation of historical non-GAAP measures to historical GAAP measures. Our Fiscal Year Our fiscal year end is January 31, and our fiscal quarters end on April 30, July 31, October 31 and January 31.

Guidance

31 Appendix

32 Appendix Key Business Metrics We monitor the following key metrics to help us evaluate our business, identify trends affecting our business, formulate business plans and make strategic decisions. Annualized Recurring Revenue (ARR) We believe that ARR is a key operating metric to measure our business because it is driven by our ability to acquire new subscription, consumption and usage-based customers, and to maintain and expand our relationship with existing customers. ARR represents the annualized revenue run rate of our subscription and consumption and usage-based agreements at the end of a reporting period, assuming contracts are renewed on their existing terms for customers that are under contracts with us. ARR is not a forecast of future revenue, which can be impacted by contract start and end dates, usage, renewal rates, and other contractual terms. Customers with ARR of $100,000 or More We believe that our ability to increase the number of customers with ARR of $100,000 or more is an indicator of our market penetration and strategic demand for our platform. Definitions Customers: We define a customer as an entity that has an active subscription for access to our platform. We count Managed Service Providers (MSPs), Managed Security Service Providers (MSSPs), Managed Detection & Response firms (MDRs), and Original Equipment Manufacturers (OEMs), who may purchase our products on behalf of multiple companies, as a single customer. We do not count our reseller or distributor channel partners as customers.

33 Appendix (Cont’d) Non-GAAP Gross Margin We define non-GAAP gross margin as GAAP gross margin, excluding stock-based compensation (SBC) expense, employer payroll tax on employee stock transactions, amortization of acquired intangible assets and acquisition-related compensation costs. Non-GAAP Operating Margin We define non-GAAP operating margin as GAAP operating margin, excluding SBC expense, employer payroll tax on employee stock transactions, amortization of acquired intangible assets, acquisition-related compensation costs and restructuring charges. Non-GAAP Net Income, Non-GAAP Net Income Margin and Non-GAAP Net Income per Share, Basic and Diluted We define non-GAAP net income as GAAP net loss excluding SBC expense, employer payroll tax on employee stock transactions, amortization of acquired intangible assets, acquisition-related compensation costs, restructuring charges, gains and losses on strategic investments and provision for income taxes. We define non-GAAP net income per share, basic and diluted, as non-GAAP net income divided by the weighted average common shares outstanding, which includes the effect of dilutive shares applying the treasury stock method. Free Cash Flow and Adjusted Free Cash Flow Free cash flow and adjusted free cash flow are non-GAAP financial measures. We define free cash flow as cash (used in) provided by operating activities less purchases of property and equipment and capitalized internal-use software costs. We define adjusted free cash flow as free cash flow, excluding the impact of discrete cash payments made under the final Assessment Agreement entered into with the Israeli Tax Authority, which is a discrete event. We believe free cash flow and adjusted free cash flow are useful indicators of liquidity that provides our management, board of directors, and investors with information about our future ability to generate or use cash to enhance the strength of our balance sheet and further invest in our business and pursue potential strategic initiatives.

(1) Effective in the first quarter of fiscal year 2027, the Company adopted a long-term projected non-GAAP tax rate of 17% to calculate non-GAAP net income. The projected rate reflects the Company’s expectations of its long-term tax structure and jurisdictional mix of income. (2) For periods in which we had diluted non-GAAP net income per share, the sum of the impact of individual reconciling items may not total to diluted non-GAAP net income per share because the basic share counts used to calculate GAAP net loss per share differ from the diluted share counts used to calculate non-GAAP net income per share, and because of rounding differences. The GAAP net loss per share calculation uses a lower share count as it excludes dilutive shares which are included in calculating the non-GAAP net income per share.
