Commitments and Contingencies Guarantees, Commitments, Letters of Credit, and Surety Bonds
As of September 30, 2025, the Company had outstanding bank guarantees, parent company guarantees, letters of credit, and surety bonds issued as performance security arrangements associated with a number of our customer projects. In addition, we have a limited number of parent company guarantees issued as payment security to certain vendors. These contractual commitments are all accounted for off-balance sheet. In the event that we fail to perform under a project backstopped by such credit support, the customer or vendor, respectively, may demand performance and/or payment, as applicable, pursuant to the terms of the project contract or vendor contract and applicable credit support instrument from the Company, surety, or bank, as the case may be. Our relationship with our sureties is such that we will indemnify the sureties for any damages and expenses they incur in connection with any of the bonds they issue on our behalf and we may be required to post collateral to support the bonds. With respect to letters of credit, in the event of non-performance under a contract, direct obligations to repay the banks may arise. The Company expects that its performance and payment obligations secured by these bank guarantees, parent company guarantees, letters of credit, and surety bonds will generally be completed in the ordinary course of business and in accordance with the applicable contractual terms.
The following table summarizes contractual obligations as of September 30, 2025. Amounts presented in the following table represent the Company's current undiscounted exposure to guarantees, commitments, letters of credit, and surety bonds and the range of maximum undiscounted potential exposure. The maximum exposure is not reduced by the amounts, if any, that could be recovered under the recourse or collateralization provisions in the guarantees, commitments, letters of credit, and surety bonds.

Purchase Commitments
The Company has commitments for minimum volumes or spend under master supply agreements with our vendors. The majority of the commitments are for purchases of battery cells and modules. Liquidated damages apply if the minimum purchase volumes or spend are not met. The Company currently expects to meet the minimum committed volumes of purchases and spend. The following table presents our future minimum purchase commitments by fiscal year, primarily for battery cells and modules, and liquidated damages, if the minimum purchase volumes or spend are not met, as of September 30, 2025.

The Company makes advance payments as capacity guarantees pursuant to purchase agreements with our suppliers. As of September 30, 2025, $53.3 million is recorded within “Advances to suppliers” and $54.6 million is recorded within “Other non-current assets” on the consolidated balance sheets.
Product Performance Guarantees
Typical energy storage products and solutions contracts and long-term service agreements contain provisions for performance liquidated damages payments if the energy storage solution fails to meet the guaranteed performance thresholds at completion of the project or throughout the service agreement period.
Warranties
The Company provides both assurance and service-type warranties to its customers. The Company recognizes revenue for service-type warranties, which are referred to as extended warranties, using a straight-line approach over the service period.
The Company provides assurance-type warranties, apart from the service-type warranties described above, related to the successful operation of battery-based energy storage solutions which typically extend from one to five years, beginning at the commercial operation date or substantial completion date, depending on the contract terms. The warranties are considered assurance-type warranties which provide a guarantee of quality of the products. The Company records an estimate of future warranty cost over the period of construction, consistent with transfer of control and revenue recognition. Additionally, we accrue estimated liability cost of specific reserves or recalls when they are probable and estimable if identified. Warranty expense is recorded as a component of “Cost of goods and services” in the Company’s consolidated statements of operations.
The Company’s assurance-type warranties are often backed by supplier covered warranties for major original equipment manufacturers (OEMs) such as batteries and inverters, which is included in our estimated warranty liability. For warranty obligations covered by supplier warranties, the Company records a corresponding asset for the contractually recoverable amounts due to the fact that the contracts are enforceable, the suppliers are financially viable, and we have a history of satisfying claims with our suppliers. The asset is recorded within “Other current assets” and “Other non-current assets” on the consolidated balance sheets.
As of September 30, 2025 and 2024, the Company accrued the below estimated warranty liabilities:
| | | | | | | | | | | |
| In thousands | September 30, |
| 2025 | | 2024 |
| Warranty balance, beginning | $ | 40,242 | | | $ | 26,909 | |
Warranties issued and assumed in period | 22,409 | | | 19,554 | |
Change in estimates | 3,173 | | | (1,692) | |
Net changes in liability for warranty expirations, costs incurred, and foreign exchange impact | (14,017) | | | (4,529) | |
| Warranty balance, ending | $ | 51,807 | | | $ | 40,242 | |
Less: Recoverable warranty costs from suppliers | 23,578 | | | 12,704 | |
Warranty balance, net of recoverable warranty costs from suppliers, at end of period | $ | 28,229 | | | $ | 27,538 | |
The key inputs and assumptions used to estimate our warranty liability are: (1) the expected failure rate, representing the number of units projected to fail or require repair; and (2) the per unit cost to repair or replace, including shipping, labor, and equipment costs.
The assurance warranty liability and related warranty asset are reviewed quarterly and may be adjusted based on actual results, performance trends, or other qualitative factors. These estimates are subject to uncertainty, and differences between the actual failure rates or replacement costs and our assumptions may result in material changes.
Legal Contingencies
From time to time, the Company may be involved in litigation, government investigations, and other regulatory or legal proceedings relating to claims that arise out of our operations and businesses and that cover a wide range of matters, including, but not limited to, securities litigation, intellectual property matters, commercial and contract disputes, insurance and property damage claims, labor and employment claims, torts and personal injury claims, product liability claims, environmental claims, fire safety claims, and warranty claims. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. It is reasonably possible that some matters could have an unfavorable result to the Company and could require the Company to pay damages or make expenditures in amounts that could be material.
2021 Overheating Event at Customer Facility
On September 4, 2021, a 300 MW energy storage facility owned by one of our customers experienced an overheating event. Fluence served as the energy storage technology provider and designed and installed portions of the facility, which was completed in the fiscal year ended September 30, 2021. No injuries were reported from the incident. The facility was taken offline as teams from Fluence, our customer, and the battery designer/manufacturer investigated the incident. Our customer released initial findings in the second fiscal quarter of 2022 on what it contends is the root cause of the incident. The customer’s stated findings, if ultimately confirmed and proven, could relate to certain scopes of work for which Fluence or its subcontractors could be responsible. The customer’s stated findings, however, could also relate to certain scopes of work for which other parties were responsible and/or relate to other causes, including the design and installation of portions of the facility over which Fluence did not have responsibility or control. The customer has alleged that Fluence is liable for the incident. At this time, Fluence cannot accept the customer’s stated findings and has denied liability. No formal legal proceedings have been commenced, but it is reasonably possible that litigation may result from this matter if a resolution cannot be achieved. Any such dispute would also likely include claims by Fluence and counterclaims by the customer relating to disputed costs arising from the original design and construction of the facility. The customer announced in July of 2022 that a large portion of the facility was back online. We are currently not able to estimate the impact that this incident may have on our financial results. To date, we do not believe that this incident has impacted the market’s adoption of our products and solutions.
2023 Project-Related Litigation
In October 2023, Fluence filed a complaint in the Superior Court of California, Contra Costa County, against Diablo Energy Storage, LLC, Empire Business Park, LLC, the Bank of New York Mellon and others, seeking approximately $37.0 million in damages arising from the supply and construction of an energy storage facility for the defendants, including for the defendants’ nonpayment of contractual amounts owed. On or about November 10, 2023, Defendant Diablo Energy Storage, LLC filed a cross-complaint against Fluence, seeking a minimum of $25.0 million of alleged damages and disgorgement of all compensation received by Fluence for the project, in the amount of approximately $230.0 million. The disgorgement claim was based upon an alleged deficiency in Fluence’s contractor license. Fluence denies the allegations in the cross-complaint and intends to vigorously defend against them and to enforce our claims against the defendants. We are currently not able to estimate the impact, if any, that this litigation may have on our reputation or financial results, or on market adoption of our products and solutions.
SEC Investigation
On February 22, 2024, as previously disclosed, a short-seller report was published about the Company (the “Short Seller Report”). In response to the Short Seller Report, the Audit Committee of the Company’s Board of Directors completed an internal investigation, with the assistance of outside counsel and forensic accountants, into the allegations in the Short Seller Report. The Company has been informed that the SEC is conducting a formal investigation and asking for certain information regarding our financial reporting. The Company is fully cooperating with the SEC’s investigation. While we are unable to predict the likely outcome of this matter or the potential cost, exposure or duration of the process, based on the information we currently possess, we do not expect the total potential cost to be material to our financial condition.
Securities Class Actions
On March 11, 2025, a putative federal securities class action complaint captioned Abramov v. Fluence Energy, Inc. et al. (Case No. 1:25-cv-00444) was filed in the United States District Court, Eastern District of Virginia, against the Company and certain of the Company’s executive officers. On April 15, 2025, a putative federal securities class action complaint captioned Kramer v. Fluence Energy, Inc. et al. (Case No. 1:25-cv-00634) was filed in the United States District Court, Eastern District of Virginia, against the Company, certain of the Company’s current and former executive officers, AES Grid Stability, and AES. Both actions purported to be brought on behalf of a purported class of stockholders, and asserted violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Rule 10b-5 promulgated thereunder. The complaints sought unspecified damages and other relief. On May 30, 2025, the United States District Court, Eastern District of Virginia ordered the consolidation of the Abramov and Kramer cases, captioned the consolidated matter In re Fluence Energy, Inc. Securities Litigation (Case No. 1:25-cv-00444-PTG-IDD) and appointed a lead plaintiff and lead counsel. The court-appointed lead plaintiff subsequently filed a consolidated complaint that asserts claims under Sections 10(b) and 20(a) of the Exchange Act, and Rule 10b-5 promulgated thereunder against the Company, AES Grid Stability, AES, and certain of the Company’s former and current executive officers. The consolidated complaint seeks unspecified damages and other relief. The defendants moved to dismiss the consolidated complaint on July 11, 2025. The Company does not believe the consolidated complaint states any meritorious claim and intends to defend this case vigorously.
Shareholder Derivative Actions
On March 25, 2025, a purported stockholder, Raffi Elmajian, filed a shareholder derivative complaint captioned Elmajian v. Nebreda et al. in the United States District Court, Eastern District of Virginia (Case No. 1:25-cv-521) against current and former officers and directors of the Company, naming the Company as a nominal defendant. On April 3, 2025, a purported stockholder, Diaa Al Amad, filed a second shareholder derivative complaint captioned Al Amad v. Nebreda et al. in the United States District Court, Eastern District of Virginia (Case No. 1:25-cv-577) against current and former officers and directors of the Company, naming the Company as a nominal defendant. Both derivative complaints allege claims under Section 14(a) of the Exchange Act and Rule 14-9 promulgated thereunder, and breaches of fiduciary duties, among other claims. The actions purport to be brought derivatively on behalf of the Company and seek damages and other various relief. On April 22, 2025, the United States District Court, Eastern District of Virginia ordered the consolidation of the Elmajian and Al Amad cases, captioned In re Fluence Energy, Inc. Shareholder Derivative Litigation (Case No.: 1:25-cv-00521). On July 21, 2025, the United States District Court, Eastern District of Virginia ordered a stay on all proceedings and deadlines in the consolidated derivative matter until resolution of the consolidated securities class action detailed above. The Company believes the claims in the complaints are without merit and intends to defend the matter vigorously.
