This follows the previously disclosed resignation of Barbara Larson from her role as Chief Financial Officer and principal financial officer, which was reported earlier under Item 5.02. The amendment mainly clarifies the exact effective date of Padgett’s interim appointment.
SentinelOne, Inc. has reached an Assessment Agreement with the Israeli Tax Authority, resolving transfer pricing and intellectual property valuation disputes for fiscal years ended January 31, 2021 through January 31, 2025. This Agreement, which incorporates principles from a bilateral Advanced Pricing Agreement process with the IRS and the Israeli Tax Authority, fully settles related tax matters for the company and its affiliates.
SentinelOne had previously recorded a $136.0 million long-term tax contingency. It now expects to record an additional $14.0 million tax expense in the fiscal year ending January 31, 2026 tied to the final resolution of its Israeli subsidiary’s intellectual property valuation.

The Agreement provides for installment payments through 2030 at 7.0% annual interest, with an option to extend up to two years. Initial payments, denominated in local currency, are approximately $30 million in the first quarter of fiscal 2027, $10 million in the fourth quarter of fiscal 2027, and $15 million in the fourth quarter of fiscal 2028, with all remaining amounts accelerating upon a change in control.
