April 14, 2026 Suzy Seandel VIA EMAIL RE: Employment Transition and Separation Agreement – CONFIDENTIAL Dear Suzy, This Employment Transition and Separation Agreement (this “Agreement”) is entered into between you, Suzy Seandel (“You” or “Employee”), and 8x8, Inc. (“8x8” or the “Company”), and sets forth the terms and conditions of your transition from full-time to part-time employment and your subsequent separation from the Company. The Company acknowledges and appreciates your significant contributions as Chief Accounting Officer. You have notified the Company of your intention to resign, and both parties wish to ensure a smooth and orderly transition of your duties. This Agreement reflects the mutual understanding reached between you and the Company regarding the terms of your transition and separation. 1. Employment Transition. (a) Full-Time Employment. Your last day of full-time employment with 8x8 will be Friday, April 24, 2026. Through that date, you will continue to perform your duties as Chief Accounting Officer and will cooperate fully in transitioning your responsibilities to your successor or other designees as directed by the Company. (b) Part-Time Employment. Effective Saturday, April 25, 2026, you will transition to part-time, hourly employment with the Company. Your part-time employment will continue through Tuesday, June 16, 2026 (the “Separation Date”). During the part-time period, you will provide transition assistance, answer questions, and support the Company’s accounting and finance functions as reasonably requested. Your hours and schedule during the part-time period will be determined by mutual agreement between you and the Company. (c) Part-Time Compensation. During the part-time period, you will be compensated on an hourly basis at a rate calculated by dividing your current annual base salary by 2,080 hours (the “Hourly Rate”). You will be paid for actual hours worked, subject to the Company’s standard payroll practices and applicable withholdings and deductions. As a non-exempt, hourly employee during the part-time period, you will be entitled to overtime pay in accordance with
applicable California and federal law for any hours worked in excess of the applicable daily or weekly thresholds. (d) Benefits Continuation. You will continue to be eligible for your current Company-sponsored benefits through June 30, 2026, subject to the terms of the applicable benefit plans. Following the termination of your Company-sponsored benefits, you will be eligible for COBRA continuation coverage in accordance with applicable law. Information regarding COBRA enrollment will be provided to you separately. (e) Equity. To the extent you hold any unvested equity awards (including stock options, restricted stock units, or other equity-based awards) under any Company equity incentive plan, vesting will cease as of the Separation Date. Any vested but unexercised stock options must be exercised in accordance with the terms of the applicable equity plan and award agreements. The Company will provide you with a separate statement detailing your vested equity holdings. 2. Separation. Your employment with the Company will terminate effective as of the Separation Date. As of the Separation Date, you will no longer hold any title, office, or position with 8x8, Inc. or any of its subsidiaries or affiliates. You agree to execute any documents reasonably necessary to effectuate your resignation from all officer positions. 3. Consideration. In consideration for your execution of this Agreement and the Release set forth in Section 4 below, the Company agrees to provide you with the following: (a) Continued part-time employment and compensation through the Separation Date as described in Section 1 above; (b) Extended benefits coverage through June 30, 2026 as described in Section 1(d) above; and (c) Payment of any accrued but unused paid time off (“PTO”) in accordance with Company policy and California law, payable on or before the Separation Date. You acknowledge that the consideration described above exceeds any compensation, benefits, or other amounts to which you would otherwise be entitled absent this Agreement, and constitutes good and valuable consideration for the promises and obligations set forth herein. 4. General Release of Claims. (a) In exchange for the consideration provided under this Agreement, you, on behalf of yourself and your heirs, executors, administrators, successors, and assigns, hereby generally and completely release, acquit, and forever discharge the Company, its parent, subsidiaries, and affiliated companies, and each of their respective current and former officers, directors, employees, shareholders, agents, attorneys, insurers, successors, and assigns (collectively, the “Released
