REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of SentinelOne, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SentinelOne, Inc. and subsidiaries (the “Company”) as of January 31, 2025 and 2024, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows, for each of the three years in the period ended January 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of January 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended January 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of January 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 26, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition — Refer to Notes 2 and 3 to the financial statements

Critical Audit Matter Description

The Company generates most of its revenue by selling subscriptions to its Singularity Platform. This includes subscription, premium support and maintenance, and other Singularity Modules, which are distinct performance obligations and are recognized (i) ratably over the subscription term as the performance obligations are satisfied, (ii) based on transaction volume, or (iii) based on certain usage-based measures. To determine the amount and pattern of revenue recognition, management identifies and evaluates the relevant contractual terms in its customer contracts based on its accounting policy (collectively “contract terms and conditions”).

Given the significance of the proper identification and evaluation of contract terms and conditions to the amount and pattern of revenue recognition, performing audit procedures to evaluate whether management properly identified the relevant contract terms and conditions that impact the amount and pattern of revenue recognition required a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the evaluation of management’s identification of the relevant contract terms and conditions that impact the amount and pattern of revenue recognition included the following, among others:

•We assessed management’s significant accounting policies related to revenue recognition for compliance with Accounting Standards Codification 606, Revenue from Contracts with Customers.

•We selected a sample of recorded revenue transactions and contracts entered during the year and performed the following procedures:

◦Obtained and read customer source documents and the contract, including master agreements and related amendments, to evaluate if relevant contract terms and conditions have been appropriately identified by management.

◦Evaluated the appropriateness of management’s determination of the impact of those terms and conditions on the amount and pattern of revenue recognition.
