Offer Letter between Barbara Larson and SentinelOne, Inc. dated September 5, 2024

1.Duties and Responsibilities. Your initial assignment will be as Chief Financial Officer reporting to Tomer Weingarten in their capacity as Chief Executive Officer. This offer letter (“Offer”) is for a full-time position. This position is designated as a section 16 Executive Officer. You will provide services at Your Approved Location, which means where you will perform work remotely, in addition to reporting to the office on a regular basis. The Company may change Your Approved Location in its sole discretion; you may not change Your Approved Location unless you satisfy the requirements of the Internal Transfer and Global Mobility Policy and obtain the requisite approvals from the People Team. The position may also require you to travel to other locations as may be necessary to fulfill your responsibilities. You will also be expected to comply with all rules, policies, and procedures of SentinelOne as they may be modified from time to time.

2.Salary. Your initial annual base salary for all hours worked will be $527,000.00, with the actual amount prorated for the actual period of employment and payable in equal installments in accordance with the Company’s customary payroll practices. This position is classified as exempt and is not subject to federal and state overtime and minimum wage requirements. Your salary is subject to periodic review and adjustment by the Company’s management, and any such adjustment is solely within the discretion of the Company’s management.

3.Variable Compensation. You will also be eligible to earn variable bonus compensation as determined in accordance with the Company’s bonus compensation policies as outlined in the Company Global Corporate Cash Bonus Plan (the “Bonus Plan”). Your target annual bonus compensation is 70% of your annual base salary, but this amount is not guaranteed. Bonus payouts are subject to SentinelOne’s sole discretion based on company and individual performance. With respect to any bonus cycles during your first year of employment, to be eligible you must have been employed on or before December 31 to be paid a bonus for that fiscal year (typically paid in April). Bonuses will be prorated based on your hire date. Unless otherwise required by law, you must be employed by SentinelOne and in good standing at the time bonuses are paid out to be eligible to earn a bonus payment. Your participation in the bonus program is subject to the terms and conditions of the Bonus Plan, which is subject to revision from time to time at SentinelOne’s sole discretion. For the avoidance of doubt, any payments made to you under the Plan are purely discretionary and do not form part of your contractual terms or remuneration under this Offer. As part of this offer, the Company is providing three months of temporary housing proximate to our headquarters in Mountain View, CA, not to exceed $20,000.00 or as otherwise agreed by the Company.

4.Benefits and Vacation. You will be eligible for benefits that are generally available to Company employees in similar positions, such as the Company’s 401(K) plan and group health insurance plan, subject to and in accordance with applicable eligibility requirements and the terms and conditions of the specific benefit arrangements. You will be eligible for paid Company holidays and to receive paid vacation under the Company’s vacation plan. Please review the relevant Company policies and/or plan documents for details regarding current benefits, including eligibility requirements. Please note that the Company may modify or eliminate specific benefits from time to time.

5.RSU Grant. The Company will recommend that the Company’s Compensation Committee of the Company’s Board of Directors (the “Committee”) grant you restricted stock units (“RSUs”) and Performance Stock Units (“PSUs”) with an aggregate value of $14,000,000.00 (the “Aggregate Equity Value”), under the Company’s 2021 Equity Incentive Plan (the “Plan”) and a related agreement. The RSU portion of the equity grant is 75% of the Aggregate Equity Value, and the PSU portion is the remaining 25%. The number of shares of the Company’s Class A common stock subject to the RSUs and PSUs will equal the Aggregate Equity Value divided by the trailing 30-calendar day average of the closing price of the Company’s Class A common stock on the New York Stock Exchange immediately preceding the date of grant. RSUs and PSUs are granted at the sole discretion of the Committee and are typically granted on the fifteenth day of next month following your Employment Start Date (defined below). After your formal written acceptance of the RSUs and PSUs and in accordance with the terms and conditions of your award agreements and the Plan, for so long as you provide continuous service to the Company, the RSUs will vest over a total of four years with 25% of the RSUs first vesting on the Vesting Date in the month following the one-year anniversary of your Employment Start Date (the “First Vesting Date”), and thereafter 1/16th of the RSUs will vest on each third Vesting Date following the First Vesting Date. For purposes of this Section 5, a “Vesting Date” is the fifth day of each month.

In regard to the PSUs, the PSUs relate to the Company’s performance for the fiscal years ending January 31, 2025 (“FY2025”), January 31, 2026 (“FY2026”), January 31, 2027 (“FY2027”) and January 31, 2028

(“FY2028”). The PSU performance metric and measurements for FY2025 have been previously approved by the Committee and are applicable to all members of the senior executive team. The PSU performance metric and measurements for FY2026, FY2027 and FY2028 will be subsequently approved by the Committee. After the end of each fiscal year, the Committee will certify the Company’s performance against the applicable metrics and determine the final number of shares that will vest from the PSUs for such fiscal year. So long as you provide continuous service to the Company, eligible PSUs relating to a fiscal year will vest on the date the performance results have been certified by the Committee (which will be no later than April 30 following the end of such fiscal year).

6.Expenses. Expenses related to your employment at the Company are subject to the Company’s Travel & Expenses Policy.

7.Withholdings. All forms of compensation paid to you as an employee of the Company will be less all applicable deductions and withholdings.

You must separately

execute and deliver a signed copy of the Agreement when you return the signed Offer to the Company. Furthermore, as we understand that you may have signed similar agreements with prior employers, we wish to impress upon you that you are absolutely prohibited from using or disclosing to the Company, directly or indirectly, any confidential or proprietary information of others, and fully expect that you will comply with your legally binding obligations to prior employers (as further detailed in the Agreement).

Similarly, the Company is free to conclude its employment relationship with you at any time, with or without cause, and with or without notice. Participation in or receipt of any RSUs, benefit, compensation, or incentive program does not change the nature of the employment relationship, which remains “at-will.” No one other than an authorized officer of the Company has the authority to enter into an agreement for employment for any specified period, or to make any promises or commitments contrary to the Company’s at-will policy. To be valid and enforceable, any employment agreement for a specified term entered into by the Company must be in writing, expressly described therein as an “employment agreement” and signed by an authorized officer of the Company.

10.Termination Benefits. The Company will recommend to the Compensation Committee that you will be eligible to receive change in control and severance payments and benefits under the Change in Control and Severance Agreement (the “Severance Agreement”) attached hereto as Exhibit B.

11.Equal Employment Opportunity.

The Company prohibits unlawful discrimination on the basis of race, color, religion, sex, pregnancy, national origin, citizenship, ancestry, age, physical or mental disability, veteran status, marital status, domestic partner status, sexual orientation, or any other consideration made unlawful by federal, state or local laws.
