Conflict Minerals Report

For the Calendar Year Ended December 31, 2025

This Conflict Minerals Report (the "Report") for Fluence Energy, Inc. (the "Company," "Fluence," "we," "us," or "our") for the reporting period from January 1, 2025 through December 31, 2025 (the "Reporting Period") has been prepared pursuant to Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the "Conflict Minerals Rule") and Form SD. The Conflict Minerals Rule was adopted by the Securities and Exchange Commission ("SEC") to implement reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The Conflict Minerals Rule imposes certain reporting obligations on SEC registrants who have a reason to believe that the products they manufacture, or contract to manufacture, contain conflict minerals that are necessary to the functionality or production of those products. Under the Conflict Minerals Rule, "conflict minerals" are defined by the SEC to be cassiterite, columbite-tantalite (coltan), gold, and wolframite, including their derivatives, which are limited to tantalum, tin, and tungsten. Pursuant to the Conflict Minerals Rule, if an SEC registrant has reason to believe that any of those conflict minerals used in their products may have originated in the Democratic Republic of the Congo ("DRC") or an adjoining country (together with the DRC, the "Covered Countries"), or the SEC registrant is unable to determine the country of origin of such conflict minerals, then the SEC registrant is required to submit a Conflict Minerals Report to the SEC that includes a description of the measures it took to exercise due diligence on the conflict minerals' source and chain of custody.

This Report describes our inquiry and the results of the inquiry, along with our due diligence process for conflict minerals for the calendar year ended December 31, 2025. The information in this Report includes the activities of all majority-owned subsidiaries and entities that are required to be consolidated by Fluence under U.S. generally accepted accounting principles.
