In connection with your separation from your role as Senior Vice President and Chief Digital Officer of Fluence Energy, LLC (“Fluence” and, together with its affiliated and related entities, the “Company”), we believe it is mutually beneficial to put in writing the terms of such separation. This letter (this “Agreement”), upon your signature, will constitute an agreement between us regarding the terms and conditions of your separation from the Company.

Effective January 1, 2024, you shall cease serving as Senior Vice President of the Company but shall remain as Chief Digital Officer of the Company, provided that such role shall immediately transition into that of non-officer employee role at the Company and you hereby resign from all roles as an officer of the Company and its subsidiaries effective January 1, 2024 (and shall take all actions requested by the Company to effect such resignations). From January 1, 2024 to January 31, 2024 (the “Transition Period”), you shall provide the transition services to the Company from time to time, as reasonably requested by you by the President and Chief Executive Officer and Chief Financial Officer (such services, the “Transition Services”), provided that the parties acknowledge and agree that the level of Transition Services to be provided to the Company is reasonably anticipated to be no less than 20% of the average level of services performed during the immediately preceding 36-month period. In consideration of the Transition Services, the Company will provide you with your annual base salary through January 31, 2024, your annual cash incentive opportunity and welfare benefits consistent with the terms thereof as provided to you as of the date hereof. Further any outstanding equity awards held by you shall continue to be eligible to vest through the end of the Transition Period. For all severance plans and in all benefit plans, you will be treated as though you retained the position as Senior Vice President and Chief Digital Officer through the end of the Transition Period.

Unless otherwise determined by the Company, your employment will terminate effective January 31, 2024 (the “Termination Date”). Subject to your compliance with this letter (including, without limitation, the provision of Transition Services through the end of the Transition Period) you shall be eligible to receive the severance payments and benefits payable upon an Involuntary Termination (as defined in the Fluence Energy, Inc. Executive Severance Plan (the “Executive Severance Plan”)) outside of the CIC Period (as defined in the Executive Severance Plan), on the terms and conditions set forth in the Executive Severance Plan (including, without limitation, the requirement to execute and not revoke a release, a copy of which attached hereto as Exhibit A, within 21 days of the Termination Date). However, at your request, the Company has agreed to pay for expenses related to specific training programs in such amount not to exceed $25,000 in lieu of any outplacement benefits you may have been provided under the terms of the Executive Severance Plan and in consideration for such payment by the Company for specific training programs, you have agreed to expressly waive and relinquish all rights and benefits to any outplacement benefits available under the Executive Severance Plan.

e.The Company is providing you with the Consideration solely to ease the impact of your separation from employment with the Company. The fact that the Company is offering Consideration to you should not be understood as nor is it intended to be an admission that any of the Released Parties has violated your rights (or the rights of anyone else) in any manner whatsoever.
