This Conflict Minerals Report (the “Report”) for Fluence Energy, Inc. (the "Company," "Fluence," "we," "us," or "our") for the reporting period from January 1, 2024 through December 31, 2024 (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, 2024. 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.

The Company was formed on June 21, 2021 and completed an initial public offering on November 1, 2021. We conduct our business operations through Fluence Energy, LLC and its direct and indirect subsidiaries. Fluence Energy, LLC was formed on June 30, 2017, as a joint venture between Siemens Industry, Inc., an indirect subsidiary of Siemens AG, and AES Grid Stability, LLC, an indirect subsidiary of The AES Corporation and commenced operations on January 1, 2018.

Fluence is a global market leader delivering intelligent energy storage and optimization software for renewables and storage. The Company's solutions and operational services are helping to create a more resilient grid and unlock the full potential of renewable portfolios. With gigawatts of projects successfully contracted, deployed, and under management across nearly 50 markets, we believe the Company is transforming the way we power our world for a more sustainable future.

During the Reporting Period, we did not directly manufacture products that contained conflict minerals necessary to the functionality or production of those products. This Report relates solely to those products that we contracted to be manufactured that may contain conflict minerals necessary to their functionality or production (the “covered products”). The covered products during the Reporting Period include our energy storage products and solutions. For a further discussion of our energy storage products and solutions, see our 2024 Annual Report. The information contained in our 2024 Annual Report is not incorporated by reference into this Report nor our Form SD and should not be considered part of this Report nor our Form SD.

We are committed to responsibly sourcing all materials and components that are used in the products contracted to be manufactured by the Company and products that may be manufactured by the Company in the future. Our suppliers are expected to comply with our Code of Conduct for Fluence and Third-Party Intermediaries (the “Supplier Code”). The Supplier Code outlines our expectations for our suppliers and includes both our commitment to conflict-free material sourcing as well as our expectations for suppliers regarding their own respective efforts in avoiding conflict minerals in their respective supply chains. We may ask our suppliers to periodically certify their compliance with the Supplier Code.

We maintain an internal process known as our “Conflict Minerals Due Diligence Program” to identify, track, and trace any potential conflict minerals within our supply chain. This initiative is designed to assess the use, sourcing, and origin of conflict minerals as well as additional raw materials. As part of this initiative, we have developed a Fluence Responsible Sourcing Policy and a Fluence Conflict Minerals Policy, both of which outline our expectations for suppliers regarding responsible sourcing practices and use of conflict minerals. These policies, along with our Supplier Code and other sustainability-related initiatives, are intended to discourage and prevent the use of conflict minerals and other raw materials linked to armed conflict, human rights violations, or environmental harm, irrespective of sourcing location. Fluence expects our suppliers to implement policies, due diligence frameworks, and management systems to ensure supply chain transparency for all materials and components used in our products. Our expectation is that these supplier-adopted due diligence policies, processes, and management systems should align with internationally recognized frameworks, such as the OECD Due

Transparency of sourcing information from our supply chain is critical to our own efforts to source responsibly. Upon request, our suppliers are expected to provide us with information on their respective sourcing, due diligence efforts, and findings for all materials and components, including conflict minerals. For more information and details on our internal responsible sourcing policies, please see our Responsible Sourcing Policy, Conflict Mineral Policy and Supplier Code, all of which are available on our website at https://fluenceenergy.com/sustainability/.

As part of the Company’s RCOI, the Company conducted an internal scoping assessment to identify materials and components that are used in our products that potentially contain conflict minerals and determine which of these materials and components are subject to the Conflict Minerals Rule (the “Scoping Assessment”). This Scoping Assessment helps us focus our RCOI efforts on relevant materials and components within the scope of the Conflict Minerals Rule. Our Responsible Sourcing Team collaborated with Fluence Supply Chain team members to conduct the Scoping Assessment, in an effort to target the correct suppliers who may provide the Company with materials and components that contain conflict minerals. We then worked directly with these targeted suppliers (as defined below) to conduct the RCOI. Due to the complexity of our energy storage solutions, and the depth, breadth, and constant evolution of our supply chain, we do not believe it is practicable to survey all our direct and indirect suppliers.

For 2024, the Company surveyed those suppliers reasonably believed or known to have provided materials, components, or products included in our covered products that may contain conflict minerals (the “targeted suppliers”), which is 42 suppliers and all of our direct suppliers. Approximately 98% of such targeted suppliers either submitted a response to the Conflict Minerals Reporting Template (“CMRT”), made available through the Responsible Minerals Initiative (“RMI”), or responded that the products they supplied to the Company contained no conflict minerals. We continued to seek responses from our remaining targeted suppliers through April 30, 2025 in preparation of this Report. If a targeted supplier did not provide a response or provided a response we believed to be incomplete or inaccurate, the Company sent follow-up requests to individual targeted suppliers pursuant to an escalation process. We reviewed completed targeted supplier responses for completeness and internal consistency. We believe that surveying targeted suppliers using their responses to the CMRT is a reasonable means of determining whether conflict minerals originated from a conflict region or helped finance armed conflict. However, there are inherent limitations in the information provided by third parties, including, but not limited to, potential inaccuracies, incompleteness, or falsified information despite our efforts to review the information. By using our supply chain due diligence processes effectively, working to drive accountability within our supply chain, and continuing our engagement and outreach efforts, we hope to continue to develop transparency into our supply chain.

We designed our due diligence measures with an aim to conform, in all material respects, to the OECD Framework. These due diligence measures take into account the OECD’s recommendations for companies in downstream segments of the supply chain, which typically are several tiers removed from, and have no direct relationship with, smelters or refiners ("SoRs"). We are many steps removed from the

1.Internal Team: The Company has an internal Responsible Sourcing team within its Investor Relations and Sustainability team to lead the supplier due diligence efforts, which includes sending CMRTs to our suppliers, collecting, and evaluating their responses, following up with suppliers who we believe have provided inadequate or incorrect information, sending reminders to suppliers who have not responded, monitoring, and tracking the status of responses, and then rolling up the reports to the Company’s customers. This Responsible Sourcing team reports directly to the Vice President of Investor Relations and Sustainability and works hand-in-hand with other members of the Supply Chain, Legal, and Compliance teams in implementing the Company’s strategy and objectives with respect to responsible sourcing, ethical business practices, and social responsibility and sustainability.

•Our Code of Conduct & Ethics reinforces our commitment to ethical business practices and our expectations that all directors, officers, and employees will adhere to ethical behaviors and will comply with the Code of Conduct & Ethics, as well as Company policies, laws, and regulations that apply to their jobs. The Code of Conduct & Ethics is available on our website at https://ir.fluenceenergy.com/corporate-governance/governance-overview.

contain conflict minerals. The Company surveys targeted suppliers annually about the potential use and origin of conflict minerals in their respective supply chains during the RCOI, including reviewing SoR information and chain of custody information, as appropriate. The Company assesses survey responses to identify sourcing and supplier risks, and follow-up, due diligence, and risk mitigation are completed as necessary. During this assessment, the Company conducts SoR due diligence, including comparing supplier-disclosed SoRs against the RMI's list of facilities identified as conformant under the RMI Responsible Mineral Assurance Process ("RMAP").

The Company conducts RCOI and due diligence on targeted suppliers using the CMRT and assesses supplier responses by analyzing each answer for completeness or inconsistencies within the data reported in the template. We follow up directly with those targeted suppliers who cannot definitively answer these questions, whose answers are ambiguous and require clarification, who fail to identify SoRs, or who fail to respond at all.

For the Reporting Period, the Company surveyed those targeted suppliers reasonably believed or known to have provided materials, components, or products that may contain conflict minerals, which was 42 suppliers, all of our direct suppliers. Approximately 98% of such targeted suppliers submitted a response. Following review of the list of SoRs maintained by the RMI and the RCOI responses received from its targeted suppliers relating to conflict minerals, the Company identified a total of 677 SoRs that may be in our supply chain related to conflict minerals. These SoRs were compared to the RMI’s list of audited SoRs for conflict minerals. Of the 677 SoRs identified that may be in our supply chain, 411 SoRs were RMI listed. Of those 411 SoRs that were RMI listed, 61% were listed as RMI conformant and approximately 1% were listed as active by RMI. Additional information concerning the SoRs identified that may be in our supply chain from our targeted suppliers is provided below.

For those SoRs identified by our targeted suppliers for conflict minerals that were not listed on the RMI list of audited SoRs or for those SoRs which were located in the Covered Countries, we issued high-risk notifications to the respective targeted suppliers utilizing such SoRs. In an effort to help mitigate responsible sourcing risks and enhance responsible sourcing practices, we have recommended that such targeted suppliers obtain independent third-party due diligence reports for any SoRs they have engaged with that fall into these high-risk categories.

We recognize the importance of greater supply chain transparency and are working to foster improvements of responsible sourcing best practices by ourselves and our suppliers. We aim to consistently engage with our suppliers to increase awareness, accountability, and transparency and are actively working to increase SoR participation in RMI and other globally recognized auditing and reporting standards.

Based on our due diligence efforts described herein, we are unable to conclusively determine the country of origin and the chain of custody of all the necessary conflict minerals in our covered products. Some of the respondents in our RCOI and due diligence processes for conflict minerals did not provide SoR information or only provided their responses at a company-wide level, rendering the Company unable to conclude whether conflict minerals from SoRs that may have been identified were actually used in Company's covered products. We also did not receive responses to our CMRT or additional due diligence inquiries from all targeted suppliers. We have therefore determined that a portion of the conflict minerals contained in our covered products may have originated from Covered Countries or may have been from recycled or scrap sources. We are, and plan to continue, working with our targeted suppliers to provide full and complete responses to our due diligence inquiries and the CMRT, as part of our efforts to promote and increase our supply chain transparency.

We anticipate that, over time, the amount of information available globally on the traceability and sourcing of conflict minerals will increase and improve our knowledge and diligence processes. As Fluence continues to conduct due diligence on its products, as discussed above, we expect to continue to refine our responsible sourcing practices and procedures as follows:


Metal	Number of total potential SoRs	Number of RMI Listed SoRs	RMI Conformant SoRs	RMI Active SoRs
Gold	277	190	93	2
Tin	220	108	74	1
Tantalum	83	51	43	0
Tungsten	97	62	39	1
Total	677	411	249	4
