SentinelOne, Inc.

Item 1.01 Entry into a Material Definitive Agreement. On November 12, 2026 (the “Effective Date”), SentinelOne, Inc. (the “Company”) entered into a credit agreement (the “Credit Agreement”) by and among the Company, as borrower, Bank of America, N.A., as administrative agent (in such capacity, the “Administrative Agent”), collateral agent and L/C issuer, and the lenders from time to time party thereto (the “Lenders”). The Credit Agreement provides for a senior secured revolving credit facility in an aggregate principal amount of $400.0 million, including a $60.0 million sublimit for the issuance of letters of credit. The Credit Agreement provides that the Company has the right at any time and from time to time to borrow revolving credit loans subject to certain customary conditions precedent and other requirements. The Company may also request incremental revolving commitments and/or incremental term loans, subject to certain conditions and limitations, but the Lenders are not obligated to provide any such incremental loans or commitments. The proceeds of the loans under the Credit Agreement may be used for working capital and general corporate purposes. As of the Effective Date, the Company had no outstanding revolving loans and approximately $0.4 million of outstanding letters of credit under the Credit Agreement. Revolving loans under the Credit Agreement may be borrowed, repaid and reborrowed, without premium or penalty (subject to customary breakage costs), until their maturity date under the Credit Agreement (the “Maturity Date”), at which time all amounts borrowed must be repaid. Revolving loans under the Credit Agreement will mature on November 12, 2031, except that if the outstanding principal amount of any Springing Maturity Debt (as defined in the Credit Agreement) exceeds the greater of $75.0 million and 50% of Consolidated EBITDA (as defined in the Credit Agreement) on any date that is 91 days prior to the final scheduled maturity date of such Springing Maturity Debt and both (i) the Company’s Liquidity (as defined in the Credit Agreement) at such time is not greater than 125% of the aggregate outstanding principal amount of such Springing Maturity Debt and (ii) the Company’s Total Leverage Ratio (as defined in the Credit Agreement) exceeds 2.50:1.00 for the then most recently completed four fiscal quarters, then the Maturity Date will be the date that is 91 days prior to the earliest scheduled maturity date of such Springing Maturity Debt. The loans under the Credit Agreement may be denominated in U.S. dollars, Euros, Sterling or Canadian Dollars. Loans under the Credit Agreement will bear interest (at the Company’s option) at a base rate, a term rate based on the Secured Overnight Financing Rate or an alternative currency term rate, plus, in each case, an applicable margin based upon the Company’s Secured Leverage Ratio (as defined in the Credit Agreement). The Company is required to pay to the Administrative Agent for the account of each Lender a commitment fee on a quarterly basis in an amount equal to 0.25% to 0.35% (depending on the Company’s Secured Leverage Ratio) of unused availability under the revolving credit facility. The Credit Agreement contains customary representations and warranties and affirmative and negative covenants. The negative covenants include restrictions on liens, investments, indebtedness, fundamental changes, restricted payments, transactions with affiliates, prepayments of subordinated debt and other matters, all subject to certain exceptions. The Credit Agreement permits the Company to repurchase shares of its common stock, subject to compliance with specified leverage ratio tests and other customary conditions, and permits the Company to make acquisitions subject to customary conditions. In addition, the Credit Agreement contains financial covenants that require the Company to maintain (i) a Secured Leverage Ratio (generally, secured debt minus up to a specified amount of the Company’s consolidated unrestricted cash, divided by Consolidated EBITDA) of less than or equal to 3.00:1.00 and (ii) a Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) (generally, Consolidated EBITDA divided by consolidated interest expense of the Company and its subsidiaries) of greater than or equal to 3.00:1.00, in each case tested at the end of each fiscal quarter. The Secured Leverage Ratio financial covenant is subject to a 0.50:1.00 step-up for four fiscal quarters following a Material Acquisition (as defined in the Credit Agreement). The obligations under the Credit Agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by substantially all of the assets of the Company and such subsidiary guarantors, subject to customary exceptions. The Credit Agreement includes customary events of default that include, among other things: non-payment of principal, interest or fees; inaccuracy of representations and warranties; violation of certain covenants; cross default to certain other indebtedness; bankruptcy and insolvency events; material judgments; change of control; and certain material ERISA events, subject to thresholds and cure periods as set forth in the Credit Agreement. Upon the occurrence and during the continuance of an event of default, the Lenders may terminate their commitments and accelerate the Company’s obligations under the Credit Agreement and may exercise certain other rights and remedies provided for under the Credit Agreement, the other loan documents and applicable law. Notwithstanding the foregoing, acceleration will be automatic in the case of bankruptcy and insolvency events of default involving the Company. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default under the Credit Agreement at a per annum rate equal to 2.00% above the otherwise applicable interest rate. The Administrative Agent and the Lenders, and certain of their respective affiliates, have provided, and in the future may provide, financial, banking and related services to the Company. These parties have received, and in the future may receive, compensation from the Company for these services. The foregoing description of the Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
