CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This Quarterly Report on Form 10-Q for the three months ended December 31, 2023 (this “Report”) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Statements regarding our future results of operations and financial position, financial and operational performance, growth and business strategy, future revenue recognition and estimated revenues, future capital expenditures and debt service obligations, projected costs, prospects, plans, and objectives of management for future operations, including, among others, statements regarding expected growth and demand for our energy storage products and services, relationships with new and existing suppliers, introduction of new products, services, and digital application offerings and adoption of such offerings by customers, expectations regarding material weakness remediation, presumptions relating to the Company’s tax receivable agreement, and potential impact from the Inflation Reduction Act of 2022 or any other proposed legislation, are forward-looking statements. In some cases, you may identify forward-looking statements by terms such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “seeks,” “intends,” “targets,” “projects,” “contemplates,” “grows,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

These forward-looking statements are subject to a number of important factors that could cause actual results to differ materially from those in the forward-looking statements, including the factors described under the headings Part I, Item 1A. “Risk Factors” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended September 30, 2023 filed with the Securities and Exchange Commission (the “SEC”) on November 29, 2023 (the “2023 Annual Report”) and Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Report. If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from what we anticipate. Many of the important factors that will determine these results are beyond our ability to control or predict. Accordingly, you should not place undue reliance on any such forward-looking statements. We qualify all forward-looking statements contained in this Report by these cautionary statements. Any forward-looking statement speaks only as of the date on which it is made, and, except as otherwise required by law, we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

FLUENCE ENERGY, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. Organization and Operations

Fluence Energy, Inc., a Delaware corporation (the “Company”), was formed on June 21, 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. (“Siemens Industry”), an indirect subsidiary of Siemens AG (“Siemens”), and AES Grid Stability, LLC (“AES Grid Stability”), an indirect subsidiary of the AES Corporation (“AES”), and commenced operations on January 1, 2018. We refer to Siemens Industry and AES Grid Stability as the “Founders” in this Quarterly Report on Form 10-Q (this “Report”).

Upon the completion of our initial public offering (“IPO”) on November 1, 2021, Fluence Energy, Inc. became a holding company whose sole material assets are the limited liability company interests (the “LLC Interests”) in Fluence Energy, LLC. All of our business is conducted through Fluence Energy, LLC, together with its subsidiaries, and the financial results of Fluence Energy, LLC are consolidated in our financial statements. Fluence Energy, LLC is taxed as a partnership for federal income tax purposes and, as a result, its members, including Fluence Energy, Inc., pay income taxes with respect to their allocable shares of its net taxable income. As of December 31, 2023, Fluence Energy, LLC had subsidiaries operating in Germany, Australia, Philippines, Chile, the Netherlands, the United States, India, Singapore, United Kingdom, Canada, Taiwan, Ireland, and Switzerland. Except where the context clearly indicates otherwise, “Fluence,” “we,” “us,” “our” or the “Company” refers to Fluence Energy, Inc. and all of its direct and indirect subsidiaries, including Fluence Energy, LLC. When used in a historical context that is prior to the completion of the IPO, “we,” “us,” “our” or “the Company” refers to Fluence Energy, LLC and its subsidiaries.

The Company’s fiscal year begins on October 1 and ends on September 30. References to “fiscal year 2022” and “fiscal year 2023” refer to the twelve months ended September 30, 2022 and September 30, 2023, respectively.

The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The Company’s CODM reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one operating segment, which corresponds to one reportable segment.

Siemens Industry Redemption

On June 30, 2022, Siemens Industry exercised its redemption right pursuant to the terms of the Third Amended and Restated Limited Liability Company Agreement of Fluence Energy, LLC (the “LLC Agreement”) with respect to its entire holding of 58,586,695 LLC Interests of Fluence Energy, LLC, together with the corresponding cancellation of an equivalent number of shares of Class B-1 common stock of Fluence Energy, Inc. (the “Siemens Redemption”).

The Company elected to settle the Siemens Redemption through the issuance of 58,586,695 shares of the Company’s Class A common stock. The Siemens Redemption settled on July 7, 2022.

The Siemens Redemption increased the beneficial ownership interest of the Company in Fluence Energy, LLC to 66.08% as of June 30, 2022. The impact of the change in ownership interest did not result in a change in control. The Siemens Redemption has been accounted for as an equity transaction and the carrying amount of non-controlling interest has been adjusted. Refer to “Consolidated statements of changes in stockholders’ equity” included herein.

Secondary Offering and AES Redemption

On December 8, 2023, AES Grid Stability, Siemens Pension-Trust e.V. (“Siemens Pension Trust”), Qatar Holding LLC (“QHL” and together with AES Grid Stability and Siemens Pension Trust in such context, the “Selling Stockholders”) closed an underwritten public offering (the “Offering”) of 18,000,000 shares of Class A common stock of the Company by the Selling Stockholders. The Company did not sell any of its shares of Class A common stock in the Offering and the Company did not receive any of the proceeds from the Offering. Pursuant to the terms of the Company’s Registration Rights Agreement, dated as of November 1, 2021, by and among the Company and the Original Equity Owners (as defined therein), the Company paid $0.7 million in certain expenses of the Selling Stockholders related to the Offering, while the Selling Stockholders paid all applicable underwriting discounts and commissions.

The AES Redemption increased the beneficial ownership interest of the Company in Fluence Energy, LLC to 71.12% as of December 8, 2023. The impact of the change in ownership interest did not result in a change in control. The AES Redemption has been accounted for as an equity transaction and the carrying amount of the non-controlling interest has been adjusted.

The results for the three months ended December 31, 2023 and 2022 are not necessarily indicative of results for the full year ending September 30, 2024 and 2023, any other interim periods, or any future year or period. The balance sheet as of September 30, 2023 included herein was derived from the audited financial statements as of that date. Certain disclosures have been condensed or omitted in the interim financial statements.

For a complete description of our significant accounting policies, refer to “Note 2 - Summary of Significant Accounting Policies and Estimates” in the audited consolidated financial statements included in our 2023 Annual Report.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Items subject to such estimates and assumptions include: the relative fair value allocations to contingencies with multiple elements, the carrying amount and estimated useful lives of long-lived assets; impairment of goodwill, intangible assets, and long-lived assets; valuation allowances for inventories; deferred tax assets; revenue recognized under the percentage-

of-completion method; accrued bonuses; and various project-related provisions including but not limited to estimated losses, warranty obligations, and liquidated damages.

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents include cash on-hand and highly liquid investments readily convertible to cash, with an original maturity of 90 days or less when purchased.

Cash restricted for use as a result of financing or other obligations is classified separately as restricted cash. If the purpose of restricted cash relates to acquiring a long-term asset, liquidating a long-term liability, or is otherwise unavailable for a period longer than one year from the balance sheet date, the restricted cash is included in “other non-current assets.” Otherwise, restricted cash is included as a separate line item on the Company’s consolidated balance sheets.

The Company typically retains cash for operations within one or more bank accounts. These accounts may hold cash in excess of the FDIC limit of $250,000. As a result, we are subject to concentration risk associated with the underlying custodial banks with whom deposits of cash and cash equivalents in excess of the FDIC limits are held. If access to these accounts is delayed or suspended indefinitely, it could have a material adverse impact on the Company’s ability to meet its financial obligations required for operations.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash at the end of each respective period as shown in the Company’s condensed consolidated balance sheets.

Revenue and Cost Recognition

The Company’s revenue recognition policy included herein is based on the application of Accounting Standards Codification - Revenue from Contracts with Customers (ASC 606). As of December 31, 2023, the Company’s revenue was generated primarily from the sale of energy storage products and solutions, providing operational services, and the sale of digital applications and solutions.

Revenue from Energy Storage Products and Solutions: The Company enters into contracts with utility companies, developers, and commercial and industrial customers to design and build battery-based energy storage products. Each storage product is customized depending on the customer’s energy needs. Customer payments are due upon meeting certain milestones that are consistent with contract-specific phases of a project. The Company determines the transaction price based on the consideration expected to be received which includes estimates of liquidated damages (“LDs”) or other variable consideration that are included in the transaction price in accordance with ASC 606. We assess any variable consideration using an expected value method. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. Generally, the Company’s contracts to design and build battery-based storage products are determined to have one performance obligation. When shipping and handling activities are performed after the customer obtains control of the product, we elect to account for shipping and handling as activities to fulfill the promise to transfer the product.

The Company recognizes revenue over time as we transfer control of our product to the customer. This transfer of control to the customer is supported by clauses in the contracts, that provides enforceable rights to payment of the transaction price associated with work performed to date for products that do not have an alternative use to the Company and/or as the project is built and control transfers depending on the contract terms.

Table of Contents

Revenue for these performance obligations is recognized using the percentage of completion method based on cost incurred as a percentage of total estimated contract costs. Standard inventory materials (including batteries, enclosures, chillers, and others, which are assembled into “cubes”) that could be used interchangeably on other projects are included in our measure of progress when they are integrated into, or restricted to, the production of the customer’s project. Due to the significance of the costs associated with cubes, our judgement on when such costs should be included in the measure of progress has a material impact on revenue recognition. Contract costs include all direct material and labor costs related to contract performance. Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Since the revenue recognition of these contracts depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are subject to revisions as the contract progresses to completion. The cumulative effects of revisions of estimated total contract costs and revenues, together with any contract reserves which may be deemed appropriate, are recorded in the period in which they occur. Due to the uncertainties inherent in the estimation process, it is reasonably possible that these estimates will be revised in a different period. When a loss is forecasted for a contract, the full amount of the anticipated loss is recognized in the period in which it is determined that a loss will occur. Refer to “Loss Contracts” below for further discussion.

Our contracts generally provide our customers the right to liquidated damages against Fluence in the event specified milestones are not met on time, or equipment is not delivered according to contract specifications. Liquidated damages are accounted for as variable consideration, and the contract price is reduced by the expected penalty or LD amount when recognizing revenue. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty is resolved. Estimating variable consideration requires certain estimates and assumptions, including whether and by how much a project will be delayed and/or will not meet performance contractual specifications. The existence and measurement of liquidated damages may also be impacted by our judgements about the probability of favorable outcomes of customer disputes involving whether certain events qualify as force majeure or the reason for the events that caused project delays. Variable consideration for liquidated damages is estimated using the expected value of the consideration to be received.

Fluence may incur additional costs to execute on the performance of a contract. When this happens, we typically attempt to recover the revenue associated with these costs via a change order with the customer. When this fact pattern occurs, it can create a timing difference between when we have incurred the cost versus when we record the revenue as costs are recognized immediately when incurred and the revenue from the change order is recognized as an increase to contract price when it is legally enforceable, which is usually upon signing a respective change order or equivalent document confirming the claim acceptance by customer. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities.

For our sale of energy storage products and solutions, services, and digital applications contracts where there are multiple performance obligations in a single contract or we sign separate contracts at or near the same time with the same customer that meet the criteria for combination, the Company allocates the consideration to the various obligations in the contract based on the relative standalone selling price. Standalone selling prices are estimated based on estimated costs plus margin taking into consideration pricing history and market factors.

Revenue from Services: The Company also enters into long-term service agreements with customers to provide operational services related to battery-based energy storage products and solutions. The services include maintenance, monitoring, and other minor services. The Company accounts for the services as a single performance obligation as the services are substantially the same and have the same pattern of transfer to customers. We typically recognize revenue overtime using a straight-line recognition method for these types of services. The Company believes using a time-based method to measure progress is appropriate as the performance obligations are satisfied evenly over time based on the fact that customers receive the services evenly. Revenue is recognized by dividing the total transaction price over the service period.

Some of the agreements also provide a commitment to perform augmentation activities which would typically be represented by installation of additional batteries, and other components as needed, to compensate for partially lost capacity due to degradation of batteries over time. The obligation to perform augmentation activities can take the form of either maintaining battery capacity above a given threshold for a stated term while others provide a fixed number of augmentations over a contract term. Augmentation arrangements that require us to maintain battery capacity above an established thresholds for a given term may be considered service-type warranties depending on the contract terms. These represent a stand-ready obligation in which the customer benefits evenly overtime, of which we recognize revenue for these arrangements using a straight-line recognition method. Alternatively, augmentation arrangements that require us to perform a fixed number of augmentations over a contract term follow the percentage of completion revenue recognition method. Since these arrangements require a fixed number of augmentations we must perform, we use the pattern of cost as a proxy to identify when our obligations are satisfied and to recognize revenue.

Revenue from Digital Applications and Solutions: The Company provides access to proprietary cloud-based Software-as-a-Service (“Saas”) through the Fluence IQ platform. The Fluence IQ platform currently includes Fluence Mosaic and Fluence Nispera. Fluence Mosaic is an intelligent bidding software for utility-scale storage and renewable assets, enabling customers to optimize asset trading in wholesale electricity markets. Fluence Mosaic is currently available in the NEM (Australia), CAISO (California), and ERCOT (Texas) markets. Fluence Nispera is our asset performance management (APM) software, which we acquired in 2022. Fluence Nispera helps customers monitor, analyze, forecast, and optimize the performance and value of renewable energy assets. Its flagship offering is an AI-driven utility-scale asset performance management platform that supports portfolios of energy storage, solar, and wind assets. Customers do not receive legal title or ownership of the applications as a result of these arrangements. The use of the Fluence IQ platform is separately identifiable from other promises that the Company offers to its customers (i.e., it is not highly interrelated or integrated with other solutions). As such, we determined that the Fluence IQ platform is accounted for as a separate performance obligation when combined with other products and services. We consider access to the platform and related support services in a customer contract to be a series of distinct services which comprise a single performance obligation because they are substantially the same and have the same pattern of transfer. We recognize revenue over time using a straight-line recognition method.

Cost of Goods and Services: Cost of goods and services consists primarily of product costs, including purchased materials and supplies, as well as costs related to shipping, customer support, product warranty and personnel. Personnel costs in cost of goods and services includes both direct labor costs as well as costs attributable to any individuals whose activities relate to the transformation of raw materials or component parts into finished goods or the transportation of materials to the customer. Cost of goods and services are recognized when services are performed, or control of goods are transferred to the customers, which is generally based upon International Commercial Terms (commonly referred to as ‘‘incoterms’’) stated in corresponding supply agreements or purchase orders. Standard inventory materials that could be used interchangeably on other projects are included in cost of goods sold when they are integrated into, or restricted to, the production of the customer’s project.

Deferred Revenue: Deferred revenue represents the excess billings to date over the amount of revenue recognized to date. Contract advances represent amounts received by the Company upon signing of the related contracts with customers. The advances are offset proportionately against progress billings. Any outstanding portion is included in deferred revenue on the accompanying consolidated balance sheets.

Loss Contracts: A contract becomes a loss contract when its estimated total costs are expected to exceed its total revenue. The Company accrues the full loss expected in the period a loss contract is identified in “Current liabilities — Accruals and provisions” and “Cost of goods and services” on the Company’s consolidated balance sheets and consolidated statements of operations and comprehensive loss, respectively.

Inventory, Net

Inventory consists of cubes, batteries and equipment, enclosures, inverters, and spare parts which are used in ongoing battery storage projects for sale. Inventory is stated at the lower of cost or net realizable value with cost being determined by the specific identification method. Costs include cost of purchase, costs of conversion and other costs incurred in bringing the inventories to their present location and condition. The Company periodically reviews its inventory for potential obsolescence and write down of its inventory, as appropriate, to net realizable value based on its assessment of usefulness and marketability conditions.

Software Development Costs

Our software development costs primarily relate to three categories: (i) internal-use software development costs, (ii) hosting arrangements which are service contracts, and (iii) external-use software development costs. We capitalize costs incurred to purchase or develop software for internal use and software to be sold or leased externally.

Internal-use software development costs are capitalized during the application development stage in accordance with ASC 350-40, Internal-Use Software. These capitalized costs are reflected in “Intangible assets, net” on the consolidated balance sheets and are amortized over the estimated useful life of the software. Our internal-use software relates to our (i) SaaS customer offerings and is amortized to “Cost of goods and services” and (ii) internally developed solutions and are amortized to “General and administrative.” The useful life of our internal-use software development costs is generally 3 to 5 years.

During the three months ended December 31, 2023 and December 31, 2022, the Company capitalized $0.9 million and $0 million, respectively, of internal-use software.

Table of Contents

Internal-use software development costs associated with hosting arrangements are capitalized during the application development stage. These are generally cloud-computing arrangements that are service contracts. The capitalized costs are reflected in “Other long-term assets” on the consolidated balance sheets and are amortized to “General and administrative” once ready for intended use over the remaining hosting period.

During the three months ended December 31, 2023 and December 31, 2022, the Company capitalized $1.5 million and $0 million, respectively, of development costs related to hosting arrangements.

External-use software development costs developed to be sold or leased externally are capitalized upon the establishment of technological feasibility for a product in accordance with ASC 985-20, Software to be Sold or Leased Externally. These software development costs are reflected in “Intangible assets, net” on our consolidated balance sheets and amortized to “Cost of goods and services” on a product basis by the greater of the straight-line method over the estimated economic life of the product or the ratio that current gross revenues for a product bear to the total current and anticipated future gross revenues for that product. The useful life of our external-use software development costs is generally 5 years.

During the three months ended December 31, 2023 and December 31, 2022, the Company capitalized $0.2 million and $0 million, respectively, of external-use software to be sold.

Fair Value Measurements

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs and to minimize the use of unobservable inputs. The following fair value hierarchy, defined by ASC 820, Fair Value Measurements, is used to classify assets and liabilities based on the observable inputs and unobservable inputs used to value the assets and liabilities:

Level 1—Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2—Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 inputs include those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted prices, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value from the perspective of a market participant. The Company does not have significant recurring Level 3 fair value measurements.

The Company’s cash equivalents include term deposits with original maturity of less than 90 days and are recorded at amortized cost. Fair value of cash equivalents approximates the carrying amount. The carrying amounts of trade receivables, accounts payable and short-term debt obligations approximate fair values due to their short maturities.

Loss per Share

As of December 31, 2023, the Company’s amended and restated certificate of incorporation authorizes three classes of common stock: Class A, Class B-1 and Class B-2. Loss per share is calculated and reported under the “two-class” method. The “two-class” method is an earnings allocation method under which loss per share is calculated for each class of common stock considering both distributions declared or accumulated and participation rights in undistributed losses as if all such loss had been distributed during the period.

Table of Contents

Basic loss per share of Class A common stock is computed by dividing net loss attributable to Class A common stockholders by the weighted average number of shares of Class A common stock outstanding during the period. Diluted net loss per share of Class A common stock is computed by adjusting the net loss available to Class A common stockholders and the weighted average shares of Class A common stock outstanding to give effect to potentially dilutive securities. Shares of our Class B-1 and Class B-2 common stock are not entitled to receive any distributions or dividends. When a common unit of Fluence Energy, LLC is redeemed for cash or Class A common stock, at the Company’s election, by a Founder who holds shares of our Class B-1 or Class B-2 common stock, as applicable, such Founder will be required to surrender a share of Class B-1 or Class B-2 common stock, as the case may be, which we will cancel for no consideration. In the event of cash settlement, the Company is required to issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fully fund the cash settlement. Therefore, we did not include shares of our Class B-1 or Class B-2 common stock in the computation of basic loss per share. As we have incurred losses for all periods presented, diluted loss per share is equal to basic loss per share because the effect of potentially dilutive securities would be antidilutive.

The following table presents the potentially dilutive securities that were excluded from the computation of diluted loss per share:


	Three Months Ended December 31,
	2023	2022
Class B-1 common stock	51,499,195	58,586,695
Outstanding pre-IPO options (“2020 Unit Option Plan”)	4,846,089	7,835,243
Outstanding phantom units	256,935	513,865
Outstanding restricted stock units (“RSUs”)	2,351,121	2,011,690
Outstanding performance share units (“PSUs”)	329,055	—
Outstanding non-qualified stock options (“NQSOs”)	132,524	—
Outstanding restricted stock (“Nispera”)	354,134	531,202

Basic and diluted net loss per share of Class A common stock for the three months ended December 31, 2023 and 2022, respectively, have been computed as follows:

Remaining Performance Obligations

The Company’s remaining performance obligations (“backlog”) represent the unrecognized revenue value of its contractual commitments, which include deferred revenue and amounts that will be billed and recognized as revenue in future periods. The Company’s backlog may vary significantly each reporting period based on the timing of major new contractual commitments and the backlog may fluctuate with currency movements. In addition, under certain circumstances, the Company’s customers have the right to terminate contracts or defer the timing of its services and their payments to the Company.

As of December 31, 2023, the Company had $3.7 billion of remaining performance obligations related to contractual commitments, of which, we expect to recognize in revenue approximately 60% in the next 12 months, with the remainder recognized in revenue in periods thereafter.

Variable Consideration

As of December 31, 2023 and September 30, 2023, transaction prices have been reduced to reflect variable consideration of $89.3 million and $84.1 million, respectively. Variable consideration primarily relates to the Company’s customers’ rights to liquidated damages in the event a specified milestone has not been met or equipment is not delivered to contract specifications. Variable consideration is estimated using the expected-value method which computes a weighted average amount based on a range of potential outcomes. In contracts in which a significant reversal may occur, we constrain the amount of revenue recognized based on our estimations using the expected-value method.

10. Debt

Revolving Credit Facility

On November 1, 2021, the Company entered into a credit agreement for a revolving credit facility (the “Revolver”), by and among Fluence Energy, LLC, as the borrower, Fluence Energy, Inc., as a parent guarantor, the subsidiary guarantors party thereto, the lenders party thereto and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent (the “Credit Agreement”). The Revolver was secured by a (i) first priority pledge of the equity securities of Fluence Energy, LLC and its subsidiaries and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, LLC, the parent guarantor and each subsidiary guarantor party thereto, in each case, subject to customary exceptions and limitations. The initial aggregate amount of commitments was $190.0 million from the lenders party thereto including JP Morgan Chase Bank, N.A., Morgan Stanley Senior Funding, Inc., Bank of America, N.A., Barclays Bank PLC, and five other banks. On June 30, 2022, the Company increased the revolving commitment available under the Revolver by $10.0 million to an aggregate of $200.0 million with the addition of UBS AG, Stamford Branch as an additional lender under the Revolver. On May 19, 2023, the Credit Agreement was amended to replace Adjusted LIBOR with Adjusted Term SOFR as the applicable benchmark interest rate with respect to certain classes of loans. The Revolver was originally scheduled to mature on November 1, 2025. The Revolving Credit Agreement was terminated effective November 22, 2023, in conjunction with the entry into the new ABL Credit Agreement (as further described below).

The Revolver bore interest at either (i) the Adjusted SOFR Rate (as defined in the Revolving Credit Agreement) plus 3.0% or (ii) the Alternate Base Rate (as defined in the Revolving Credit Agreement) plus 2.0% (subject to customary LIBOR replacement provisions and alternative benchmark rates including customary spread adjustments with respect to borrowings in foreign currency), at the option of Fluence Energy, LLC. Fluence Energy, LLC was required to pay to the lenders a commitment fee of 0.55% per annum on the average daily unused portion of the revolving commitments through maturity. The Revolver also provided for up to $200.0 million in letter of credit issuances, which required customary issuance and administration fees, as well as a fronting fee payable to each issuer thereof and a letter of credit participation fee of 2.75% per annum payable to the lenders.

The Revolving Credit Agreement contained covenants that, among other things, restricted our ability to incur additional indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; make dividends, distributions, or other restricted payments; and engage in affiliate transactions. Under the terms of the Revolving Credit Agreement, Fluence Energy, LLC and its subsidiaries were limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions, including among others (i) the ability to make investments of up to the greater of (a) $10,500,000 and (b) 1.5% of the consolidated assets of Fluence Energy, Inc. and its subsidiaries, and (ii) the ability to issue dividends and make other restricted payments (a) if after giving pro forma effect to such dividend or other restricted payment the Total Liquidity (as defined in the Revolving Credit Agreement) of Fluence Energy, Inc. and its subsidiaries party to the Revolving Credit Agreement was at least $600,000,000, or (b) such dividend or other restricted payment was made to reimburse Fluence Energy, Inc. for certain tax distributions under the LLC Agreement and certain payments under the Company’s Tax Receivable Agreement and certain operational expenses incurred in connection with the ownership and management of Fluence Energy, LLC. In addition, we were required to maintain (i) minimum liquidity and gross revenue requirements, in each case, until consolidated EBITDA reached $150.0 million for the most recent four fiscal quarters and we made an election, and (ii) thereafter, a maximum total leverage ratio and a minimum interest coverage ratio. Such covenants were tested on a quarterly basis.

Asset-Based Lending Facility

On November 22, 2023, the Company entered into an asset-based syndicated credit agreement with revolving commitments in an aggregate principal amount of $400.0 million (the "ABL Facility"), by and among Fluence Energy, LLC, as parent borrower, Fluence Energy, Inc., as parent, the other borrowers party thereto, the other guarantors party thereto, the lenders party thereto (the “ABL Lenders”), and Barclays Bank PLC (“Barclays”), as administrative agent (the "ABL Credit Agreement"). The ABL Facility is secured by (i) a first priority pledge of Fluence Energy, Inc.’s equity interests in Fluence Energy, LLC and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, Inc., Fluence Energy, LLC and Fluence Energy Global Production Operation, LLC, in each case, subject to customary exceptions and limitations. Borrowings under the ABL Facility will mature, and lending commitments thereunder will terminate, on November 22, 2027. The Company entered into that certain Master Assignment and Assumption and Issuing Bank Joinder, effective December 15, 2023, with Citibank N.A., the ABL Lenders, and Barclays, adding Citibank N.A. as a lender party to the ABL Facility (the “ABL Joinder”). Borrowing availability under the ABL Facility is determined by a borrowing base calculation that is based on specified percentages of U.S. eligible inventory, net orderly liquidation value of most recent inventory appraisal, and U.S. eligible in-transit inventory, less the aggregate amount of any reserves.

The ABL Credit Agreement provides for a full cash dominion period (a) if an event of default is occurring or (b) beginning on the date on which Excess Availability is less than the greater of (i) 12.5% of the Line Cap and (ii) if the borrowing base then in effect is (A) less than $200.0 million, $25.0 million and (B) greater than or equal to $200.0 million, $50.0 million. Line Cap is defined under the ABL Facility as the lesser of the total commitments of the ABL Lenders and the borrowing base. Excess Availability is defined under the ABL Facility as an amount equal to (a) the lesser of (i) the total commitments of all lenders and (ii) the borrowing base, minus (b) total revolving extensions of credit then outstanding at anytime.

The ABL Credit Agreement sets forth that (i) loans comprising each ABR Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Alternate Base Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability (as defined in the ABL Credit Agreement) during the applicable determination period, (ii) loans comprising each Canadian Prime Loan Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Canadian Prime Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability during the applicable determination period, and (iii) the loans comprising each Term Benchmark Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Adjusted Term SOFR Rate, the Adjusted EURIBOR Rate or Adjusted Term CORRA (each as defined in the ABL Credit Agreement), as applicable, plus an additional margin ranging from 2.00% to 2.50%, depending on the Average Excess Availability during the applicable determination period, in each instance subject to customary benchmark replacement provisions. Fluence Energy, LLC is required to pay to the ABL Lenders a commitment fee on the average daily unused portion of the commitments through maturity, which shall accrue at the rate of (a) until the last day of the first full calendar quarter following the closing of the ABL Facility, 0.450% per annum, and (b) thereafter, 0.450% per annum if average revolving loan utilization is less than or equal to 50% and 0.375% per annum if average revolving loan utilization is greater than 50%. The ABL Facility also provides for a letter of credit sublimit in the amount of $200.0 million, if certain conditions are met. Each letter of credit issuance will be conditioned upon, among other conditions, the payment of certain customary issuance and administration fees, as well as payment of a fronting fee to each issuer thereof and payment of a letter of credit participation fee payable to the ABL Lenders.

The ABL Credit Agreement contains customary covenants for this type of financing, including, but not limited to, covenants that restrict our ability to incur indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; pay dividends, make distributions or other restricted payments; and engage in affiliate transactions. The ABL Credit Agreement limits our ability to make certain payments, including dividends and distributions on Fluence Energy, LLC’s equity, the Company’s equity and other restricted payments. Under the terms of the ABL Credit Agreement, Fluence Energy, LLC and its subsidiaries are currently limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions. In addition, if certain payment conditions under the ABL Credit Agreement are satisfied, including the satisfaction of a minimum excess availability requirement, then additional specified transactions may be made by the Company and its subsidiaries. The Company agreed that it will not, and its subsidiaries will not, permit Total Liquidity (as defined in the ABL Credit Agreement) at any time to be less than the greater of (i) 20% of the Line Cap then in effect and (ii) $64.0 million, and the Company agreed that it will not, and its subsidiaries will not, permit Excess Availability to be less than the greater of (i) $15.0 million and (ii) 10% of the Line Cap then in effect. Such covenants will be tested on a quarterly basis and upon certain restricted payments, the incurrence of indebtedness, certain dispositions and other specified transactions. As of December 31, 2023, we were in compliance with all such covenants or maintained availability above such covenant triggers.

Table of Contents

As of December 31, 2023, we had no borrowings under the ABL Facility and $0 of letters of credit outstanding, and availability under the facility of $75.2 million.

Borrowings Against Note Receivable - Pledged as Collateral

In December 2022, the Company transferred $24.3 million in customer receivables to Standard Chartered Bank (“SCB”) in the Philippines for proceeds of $21.1 million. The receivables all related to our largest customer in that country. The underlying receivables transferred were previously aggregated into a long term note, with interest, and has a maturity date of September 30, 2024. In April 2023, the Company aggregated into an additional long term note and transferred an additional $30.9 million in receivables with the same customer to SCB for proceeds of $27.0 million, upon substantially similar terms as the December 2022 transfer and has a maturity date of December 27, 2024. These transactions are treated as secured borrowings as the Company did not transfer the entire note receivables due from the customer to SCB. The Company continues to receive quarterly interest income from the customer, while SCB is responsible for collecting payments on the principal balances which represent the initial receivable balances from the customer. The Company has no other continuing involvement or exposure related to the underlying receivables. For the three months ended December 31, 2023, the Company recorded net interest income of $0.1 million, which represents the aggregate of $1.2 million in interest income and $1.1 million in interest expense recorded in “Interest income, net.”

Refer to “Note 13 - Related-Party Transactions” for details regarding borrowings from related parties.

11. Income Taxes

The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items.

Income tax benefit was $1.2 million and $0.6 million for the three months ended December 31, 2023 and 2022, respectively. The effective tax rate for the three months ended December 31, 2023 and 2022 was 4.6% and 1.6%, respectively. For the three months ended December 31, 2023, the Company’s effective tax rate differs from the U.S. statutory tax rate of 21% primarily due to valuation allowances. For the three months ended December 31, 2022, the Company’s effective tax rate differs from the U.S. statutory tax rate of 21% primarily due to flow-through losses attributable to the Founders, valuation allowances, and foreign exchange gains.

As of each of December 31, 2023 and September 30, 2023, the Company does not believe it has any significant uncertain tax positions and therefore, has not recorded any unrecognized tax benefits.

The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establishes valuation allowances when it is more-likely-than-not that all or a portion of a deferred tax asset may not be realized. As of December 31, 2023 and September 30, 2023, the Company had recorded a full valuation allowance against deferred tax assets on Fluence Energy, Inc. primarily related to its investment in Fluence Energy, LLC, as well as on certain foreign subsidiaries based on the weight of available evidence, including cumulative losses. In the event that the valuation allowance related to tax benefits associated with the Tax Receivable Agreement is released in a future period, a Tax Receivable Agreement liability will be recorded based on the amounts probable and reasonably estimable in accordance with ASC 450.

12. Commitments and Contingencies

Guarantees, Commitments, Letter of Credits and Surety Bonds

As of December 31, 2023, the Company had outstanding bank guarantees, parent guarantees, letters of credit, and surety bonds issued as performance security arrangements for a number of our customer projects. 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 may demand performance and/or payment, as applicable, pursuant to the terms of the project 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 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. The Company expects that its performance 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.

Typical energy storage products and solutions contracts and long-term service agreements contain provisions for performance liquidated damages payments if the solution fails to meet the guaranteed performance thresholds at completion of the project or throughout the service agreement period.

Table of Contents

The following table summarizes contingent contractual obligations as of December 31, 2023. 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.


	Amount (in $ millions)	Number of Agreements	Maximum Exposure Range for Each Agreement (in $ millions)
Guarantees and commitments	$1,613	50	$0 - 445.8
Letters of credit under the bilateral credit facility (a)	125	32	0 - 29.5
Letters of credit under ABL Credit Agreement	—	—	0 - 0
Surety bonds	389	39	0 - 81.9
Total	$2,127	121

(a) In conjunction with the termination of the Revolving Credit Agreement on November 22, 2023 (as described above in “Note 10 – Debt”), the outstanding letters of credit under the terminated agreement were transferred to a bilateral credit facility with JP Morgan Chase Bank, N.A.

Purchase Commitments

The Company has commitments for minimum volumes of purchases of battery modules under a master supply agreement. Liquidated damages apply if the minimum purchase volumes are not met. The Company expects to meet the minimum committed volumes of purchases. The following table presents our future minimum purchase commitments by fiscal year, primarily for battery modules, and liquidated damages, if the minimum purchase volumes are not met, as of December 31, 2023:


in thousands	Purchase Commitments		Liquidated Damages
2024	$	16,531	$	—
2025	232,107		9,000
2026	757,133		16,200
2027	750,000		16,200
2028 and thereafter	2,250,000		48,600

Total	$	4,005,771	$	90,000

During the three months ended December 31, 2021, the Company made a $60.0 million advance payment as a capacity guarantee pursuant to a purchase agreement with one of our suppliers, of which, as of December 31, 2023, the balance of $12.8 million is recorded within “Advances to suppliers” on the condensed consolidated balance sheets.

Negotiations with our Largest Battery Module Vendor

In December 2021, the Company entered negotiations with our largest battery module vendor to amend the battery supply agreement. As part of the discussions, the vendor sought to renegotiate the price the Company would pay for battery modules purchased in calendar year 2022 as well as those expected to be purchased during the remainder of calendar year 2022 and calendar year 2023. As part of these negotiations, the Company also discussed settlement of contractual claims by Fluence to the vendor. These negotiations continued throughout calendar year 2022. On December 15, 2022, the Company finalized an agreement with the vendor, amending the supply agreement and resolving Fluence’s claims. The approximately $19.5 million settlement for the Company’s claims was recognized as a reduction of costs of goods and services for the three months ended December 31, 2022.

Warranties

The Company is party to both assurance and service-type warranties for various lengths of time. The Company recognizes revenue for service- type warranties using a straight-line approach.

Table of Contents

The Company provides a limited warranty related to the successful operation of battery-based energy storage solutions, apart from the service-type warranties described above and are normally provided for a limited period of time from one to five years, after the commercial operation date or substantial completion depending on the contract terms. The warranties are considered assurance-type warranties which provide a guarantee of quality of the products. For assurance-type warranties, the Company records an estimate of future warranty cost over the period of construction, consistent with transfer of control and revenue recognition on the equipment or battery-based energy storage products. Furthermore, we accrue the estimated liability cost of specific reserves or recalls when they are probable and estimable if identified. Warranty expense is recorded as a component of “Costs of goods and services” in the Company’s condensed 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. The Company records a corresponding asset for a portion of the warranty cost to be covered by the supplier warranty 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 with in “Other current assets” and “Other non-current assets” on the condensed consolidated balance sheet.

As of December 31, 2023 and September 30, 2023, the Company accrued the below estimated warranty liabilities, which the table reflects three months activity and twelve months activity:


In thousands	December 31, 2023		September 30, 2023
Warranty balance, beginning	$	26,909	1,625
Warranties issued and assumed in period	2,517		12,168
Change in estimates	—		8,288
Change in balance sheet presentation	—		10,307
Net changes in liability for warranty expirations, costs incurred, and foreign exchange impact	(887)		(5,479)
Warranty balance, ending	$	28,539	$	26,909
Less: Recoverable warranty costs from suppliers	10,959		10,307
Warranty balance, net of recoverable warranty costs from suppliers, at end of period	$	17,580	$	16,602

Effective March 31, 2023, the Company updated its estimation model for calculating the recurring warranty reserve rate, which is a key input into our estimated assurance-type warranty liability. We then subsequently updated the presentation effective September 30, 2023, to present the full warranty liability and record a corresponding asset for recoverable warranty costs from suppliers.

The key inputs and assumptions used by us to estimate our warranty liability are: (1) the number of units expected to fail or be replaced over time (i.e., failure rate); and (2) the per unit cost of replacement, including shipping, labor costs, and costs for equipment necessary for repair or replacement that are expected to be incurred to replace or repair failed units over time (i.e., repair or replacement cost). The Company’s Safety and Quality department has primary responsibility to determine the estimated failure rates for each generation of product.

The key inputs and assumptions used in calculating the estimated assurance warranty liability are reviewed by management on as needed basis. The Company may make additional adjustments to the estimated assurance warranty liability based on our comparison of actual warranty results to expected results for significant differences or based on performance trends or other qualitative factors. If actual failure rates, or replacement costs differ from our estimates in future periods, changes to these estimates may be required, resulting in increases or decreases in our estimated assurance warranty liability which may be material. As we are in an evolving market, there is a degree of estimation uncertainty regarding our estimated recurring warranty accrual rate.

Legal Contingencies

From time to time, the Company may be involved in litigation relating to claims that arise out of our operations and businesses and that cover a wide range of matters, including, but not limited to, intellectual property matters, contract and employment claims, personal injury claims, product liability 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 designed and installed portions of the facility, which was completed in fiscal year 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. At this time, Fluence cannot comment on or accept the customer’s stated findings. 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 but has not yet demanded a specific amount of compensation nor alleged a particular level of responsibility. Fluence 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.

2022 Overheating Event at Customer Facility

On April 18, 2022, a 10 MW energy storage facility in Chandler, Arizona owned by AES experienced an overheating event. Fluence served as the energy storage technology provider for the facility, which was completed in 2019, and Fluence previously provided maintenance services for the facility. There were no injuries. The facility has been taken offline as teams from Fluence, AES, and the battery manufacturer continue to investigate the incident. We are currently not able to estimate the impact, if any, that this incident may have on our reputation or financial results, or on market adoption of our products.

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.

13. Related-Party Transactions

Related parties are represented by AES and Siemens, their respective subsidiaries and other entities under common control.

14. Stock-Based Compensation

Option Plan

In 2020, the Company established the 2020 Unit Option Plan (the “Option Plan”) under which employees, directors, and consultants, were originally granted non-qualified options to purchase Class A-1 units of Fluence Energy, LLC. As of September 30, 2021, the Company determined that achievement of the performance conditions related to awards granted under the Option Plan was not probable and therefore, no expense was recognized for the non-qualified options during the fiscal year ended September 30, 2021. The completion of the IPO on November 1, 2021 resulted in achievement of the performance condition for the majority of the underlying awards granted under the Option Plan. In connection with the IPO, the non-qualified options were converted into non-qualified stock options to purchase shares of Class A common stock of Fluence Energy, Inc. Non-qualified stock options under the Option Plan have a contractual term of ten years from the date of grant and an exercise price of $2.45. The Company estimated the fair value of the awards using the Black-Scholes option-pricing model. The outstanding awards will continue to be governed by the existing terms under the Option Plan. The Option Plan is accounted for as an equity plan. The Company will not make any further awards under the Option Plan.

As of December 31, 2023, 4,846,089 stock options under the Option Plan remain outstanding with unrecognized stock compensation expense of $0.1 million.

Phantom Units

Employees, directors, and consultants were granted compensation under the Phantom Equity Incentive Plan (the “Phantom Incentive Plan”). As of September 30, 2021, the Company determined that achievement of the performance conditions related to awards granted under the Phantom Incentive Plan was not probable and therefore, no expense was recognized for the phantom units during the fiscal year ended September 30, 2021. The completion of the IPO on November 1, 2021 resulted in achievement of the performance condition for the majority of the underlying awards granted under the Phantom Incentive Plan. At the completion of the IPO, a portion of the awards to the Company’s officers were modified, extending out the vesting period. All outstanding awards relate to those held by the Company’s officers as a result of the modification. The Company will not make any further awards under the Phantom Incentive Plan.

As of December 31, 2023, 256,935 phantom unit awards previously issued remained outstanding with unrecognized stock compensation expense of $0.9 million.

2021 Stock-Based Compensation Plan

During fiscal year 2021, the Company established the 2021 Incentive Award Plan (the “2021 Incentive Plan”) which reserved 9,500,000 shares of Class A common stock of Fluence Energy, Inc. for issuance to management, other employees, consultants, and board members of the Company. The 2021 Incentive Plan governs both equity-based and cash-based awards, including incentive stock options, non-qualified stock options, performance share units (“PSUs”) and restricted stock units (“RSUs”). Employee stock-based awards currently issued pursuant to the 2021 Incentive Plan that are expected to be settled by issuing shares of Class A common stock are recorded as equity awards. The 2021 Incentive Plan is accounted for as an equity plan. The Company accounts for forfeitures as they occur.

Restricted Stock Units

RSUs granted under the 2021 Incentive Plan vest ratably at one-third annually on the anniversary of the grant date over a three-year period pursuant to the terms of their applicable award agreements. The Company generally expenses the grant date fair value of the awards on a straight-line basis over each of the three separately vesting tranches within a given grant. There is no contractual term on the RSUs granted under the 2021 Incentive Plan. The Company estimated the fair value of the awards using the market value of our Class A common stock. The market value of our Class A common stock is calculated using the closing price of our Class A common stock on the date of grant. The following table summarizes activity under the 2021 Incentive Plan for the three months ended December 31, 2023:

Table of Contents


			Number of RSUs
Outstanding as of October 1, 2023			1,843,570
Granted			741,775
Vested			(169,800)
Forfeited			(64,424)
Outstanding as of December 31, 2023			2,351,121

As of December 31, 2023, 2,351,121 restricted stock units previously issued remained outstanding with unrecognized stock compensation expense of $28.8 million.

Non-Qualified Stock Options

During the three months December 31, 2023, the Company granted 132,524 non-qualified stock options to purchase Class A common stock under the 2021 Incentive Plan with an exercise price of $21.93. Non-qualified stock options under the 2021 Incentive Plan have a contractual term of ten years from the date of grant. The Company estimated the fair value of the awards using the Black-Scholes option-pricing model. The non-qualified stock options granted under the 2021 Incentive Plan vest ratably at one-third annually on the anniversary of the grant date over a three-year period pursuant to the terms of their applicable award agreements. The Company generally expenses the grant date fair value of the awards on a straight-line basis over each of the three separately vesting tranches within a given grant.

As of December 31, 2023, 132,524 non-qualified stock options previously issued remained outstanding with unrecognized stock compensation expense of $2.4 million.

Performance Share Units

During the three months ended December 31, 2023, the Company granted 329,055 performance share units redeemable for Class A common stock under the 2021 Incentive Plan. The PSUs are considered fully vested when both the performance and service based requirements are met in accordance with the vesting requirements and will be settled in shares no more than 60 days after September 30, 2026. The performance criteria is based on target revenue and adjusted EBITDA for the performance period set by the Compensation and Human Resources Committee of the Company’s Board of Directors. The awards can be paid out in a range of 50% to 200%, with 0% paid out for below-threshold performance, based on the achievement of the performance criteria and upon continued service through the performance period. The Company estimated the fair value of the awards using the market value of our common stock. The market value of our common stock is calculated using the closing price of our common stock on the date of grant. The Company monitors the achievement of the performance criteria and expenses ratably the grant date fair value of the awards probable to vest over the requisite service period. If there are changes to the amount of probable awards to vest based on achievement of performance criteria, the related stock-based compensation expense may be significantly increased or reduced in the period that our estimate changes.

As of December 31, 2023, 329,055 performance share units previously issued remained outstanding with unrecognized stock compensation expense of $7.0 million.

Other

In connection with the acquisition of Nispera AG in 2022, Fluence issued 531,202 shares of restricted stock to Nispera’s management team. The estimated post combination expense to the Company as a result of the business combination was approximately $6.9 million which will be recognized on a straight-line basis over the remaining service period that was stipulated in each holder’s original restricted stock agreement.

15. Investment in Joint Venture

On August 5, 2022, Fluence Energy Singapore PTE. LTD., a subsidiary of Fluence Energy, LLC, and ReNew Power entered into an agreement to form a partnership in India for an initial investment of $5.0 million, plus a line of credit of $15.0 million each for a 50% interest in the partnership. The Company funded the investment and the joint venture commenced operations in the first quarter of fiscal year 2023. The investment is recorded in “Other non-current assets” on our condensed consolidated balance sheet. The investment is accounted for under the equity method with results being reported by Fluence one quarter in arrears. The joint venture is not considered a variable interest entity and we do not consolidate the joint venture as we do not hold a controlling financial interest. The Company recorded an insignificant equity method loss on the investment for the three months ended December 31, 2023.

16. Supply Chain Financing

The Company has provided certain of our suppliers with access to a supply chain financing program through a third-party financing institution (“SCF Bank”). This program allows the Company to seek extended payment terms up to 120 days with our suppliers and allows our suppliers to monetize their receivables prior to the payment due date, subject to a discount. The Company does not pledge any assets as collateral under the program. Once a supplier elects to participate in the program and reaches an agreement with SCF Bank, the supplier chooses which individual invoices to sell to the SCF Bank. The Company then pays SCF Bank on the invoice due date. The Company has no economic interest in a supplier’s decision to sell an underlying receivable to SCF Bank. The agreements between our suppliers and SCF Bank are solely at their discretion and are negotiated directly between those two parties. Our suppliers’ ability to continue using such agreements is primarily dependent upon the strength of our financial condition and guarantees issued by AES and Siemens. As of December 31, 2023, AES and Siemens issued guarantees of $50 million each, for a total of $100 million, to SCF Bank on our behalf. The Company’s outstanding obligations confirmed as valid under its supplier financing program for periods ended December 31, 2023, and September 30, 2023, are as follows:


In thousands	December 31, 2023		September 30, 2023
Obligations outstanding at the beginning of the period	$	30,001	$	24,728

Invoices paid during the period	(30,357)		(29,842)
Obligations outstanding at the end of the period	$	45,882	$	30,001

As of December 31, 2023, three suppliers were actively participating in the supply chain financing program. All outstanding payments owed under the program are recorded within “Accounts payable” on the condensed consolidated balance sheets.

Refer to “Consolidated statements of changes in stockholders’ equity” included herein.

Negotiations with our Largest Battery Module Vendor

In December 2021, we entered negotiations with our largest battery module vendor to amend our battery supply agreement. As part of the discussions, the vendor sought to renegotiate the price we were to pay for battery modules purchased in calendar year 2022, as well as those expected to be purchased during the remainder of calendar year 2022 and calendar year 2023. As part of these negotiations, we also discussed settlement of contractual claims by Fluence to the vendor. These negotiations continued throughout calendar year 2022. On December 15, 2022, we finalized an agreement with the vendor, amending the supply agreement and resolving our claims. The approximately $19.5 million settlement for our claims was recognized as a reduction of costs of goods and services for the three months ended December 31, 2022.

2021 Cargo Loss Incident

On April 28, 2021, the Company was notified of an emergency aboard a vessel carrying Fluence inventory. This incident (the “Cargo Loss Incident”) resulted in damage to a portion of our cargo aboard the vessel. The Company has recorded $13.0 million provision to its inventory as of September 30, 2021, based on the net realizable value of cargo that was destroyed. During fiscal year 2022, $13.0 million of inventory was written off against the provision. In addition to the inventory losses, we incurred incremental expenses related to the incident, primarily consisting of inspection costs, project cost overruns due to logistical changes, legal fees, fees to dispose of the damaged cargo, and additional cost to replace the damaged cargo. We received an aggregate of $10.0 million in insurance proceeds related to non-disputed claims, $7.5 million of which was collected in October 2021 and the remaining $2.5 million was collected in April 2022. As of December 31, 2023, we expect to continue to incur legal fees as plaintiff in the pending matter relating to this incident.

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 fiscal year 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 but has not yet demanded a specific amount of compensation nor alleged a particular level of responsibility. 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.

2022 Overheating Event at Customer Facility

On April 18, 2022, a 10 MW energy storage facility in Chandler, Arizona owned by AES experienced an overheating event. Fluence served as the energy storage technology provider for the facility, which was completed in 2019, and Fluence currently provides maintenance services for the facility. There were no injuries. The facility has been taken offline as teams from Fluence, AES, and the battery manufacturer investigate the incident. We are currently not able to estimate the impact, if any, that this incident may have on our reputation or financial results, or on market adoption of our products and solutions.

Key Factors and Trends Affecting our Performance

We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including those discussed below and those in Part I, Item 1A. “Risk Factors” in our 2023 Annual Report.

Lithium-ion Battery Cost

Our revenue growth is directly tied to the continued adoption of energy storage products and solutions by our customers. The cost of lithium-ion energy storage hardware has declined significantly in the last decade and has resulted in a large addressable market today.

However, according to BloombergNEF’s 2022 (issued December 2022) battery price survey, higher raw material costs pushed the average price of lithium-ion battery packs up in calendar year 2022. We have seen prices for lithium-ion battery packs decline during calendar year 2023 and in January of 2024. The 2022 price increase marked the first annual increase in price since at least 2018. The market for energy storage is rapidly evolving, and while we believe costs will continue to decline over the long term, there is no guarantee that they will decline or decline at the rates we expect. If costs do not continue to decline long term, this could adversely affect our ability to increase our revenue or grow our business.

Supply Chain

Although we do not rely on any single supplier for the majority of our key components, including our batteries and inverters, we do obtain certain key components from a limited number of suppliers. If one or more suppliers were unable to satisfy our requirements for particular key components, we could experience a disruption to our operations and delays in completing our projects as alternative suppliers are identified and qualified, and new supply arrangements are entered into. Moreover, if one of our suppliers is unable to satisfy our requirements and we turn to another supplier, such replacement supply arrangements may be on less advantageous terms for us and result in higher costs to the Company. In addition, a number of our suppliers are situated outside of the United States, which exposes us to changes in international trade regulations, taxes, tariffs, and/or quotas. As of the date of this Report, we believe that we have adequate access to our key components to meet the needs of our operations. See Part I, Item IA. “Risk Factors” of the 2023 Annual Report for further discussion on supply chain risks for our business.

Increasing Deployment of Renewable Energy

Deployment of renewable energy resources has accelerated over the last decade, and solar and wind have become a low-cost energy source. BloombergNEF estimates that renewable energy is expected to represent 70% of all new global capacity installations over the next ten years. Energy storage is critical to reducing the intermittency and volatility of renewable energy generation. However, there is no guarantee that the deployment of renewable energy will occur at the rate estimated by BloombergNEF or that such renewable energy will rely on lithium-ion battery technology for energy storage. Inflationary pressures, supply chain disruptions, geo-political conflicts, government regulations and incentives, and other factors could result in fluctuations in demand for and deployment of renewable energy resources, adversely affecting our revenue and ability to generate profits in the future. See Part I, Item IA. “Risk Factors” of the 2023 Annual Report for further discussion on these risks.

Competition

The energy storage industry is competitive and continuously evolving. Our energy storage products and solutions, services, and digital applications are highly specialized and specific to the clean energy industry. The unique expertise required to design these offerings as well as integrate these solutions for our customers can be very complex and technical, however, the number of additional companies offering similar products and services is growing every year. In addition, we are continuously engaging in developing new use cases and opening new market segments, which are often less contested. We believe that competitive factors in the energy storage market include, but are not limited to:

•safety, reliability and quality;

•stability in supply chain;

•performance of energy storage products and solutions, services and digital applications;

•historical customer track record (as the market and industry continues to grow);

•experience in the battery energy storage system market (both of the Company and key members of leadership);

•technological expertise and innovation;

•comprehensive solutions and offerings from a single provider;

•brand recognition;

•certain government initiatives, legislation, regulations, and policies;

•ease of integration; and

•seamless hardware and software-enabled service offerings.

Our competition varies by geography, country, grid service, and customer segment. There is a rising demand for energy storage products and solutions globally, and with that growing demand, we see increasing numbers of new entrants and potential entrants in the energy storage space. We believe that a key differentiator for Fluence from our competitors is our ability to identify customer needs and deliver customer-centric products, services, and use cases that can compete in the market either as packages or standalone offerings. We believe we compete favorably based on performance and value-creation, including low total cost of ownership, long-term reliability, varied service options, and convenient and efficient sales and delivery processes.

Seasonality

Through fiscal year 2021, we experienced variability in the timing of our order intake, with higher volumes of orders coming the second half of our fiscal year. However, in fiscal years 2022 and 2023, order intake was relatively consistent across each quarter. In fiscal year 2024, we currently expect to see a higher amount of our order intake in the second half of the fiscal year. The variability in our order intake is primarily driven due to timing of customer approvals which typically coincides with their own internal budgeting processes. The timing of our order intake can be difficult to predict, and could result in significant variation among fiscal quarters.

Government Regulation and Compliance

Governments across the globe have announced and implemented various policies, regulation and legislation to support the transition from fossil fuels to low-carbon forms of energy and to support and accelerate adoption of clean and/or reliable distributed generation technologies. The operation of our business and our customers’ use of our products and services are impacted by these various government actions. For example, in August 2022, the United States passed the Inflation Reduction Act of 2022 (the “IRA”), which consists of a number of provisions aimed directly at confronting the climate change crisis. Among other things, the IRA introduced an investment tax credit (ITC) for standalone energy storage

Table of Contents

and it contains provisions with incentives for grid modernization equipment including domestic battery cell manufacturing, battery module manufacturing and its components, as well as various upstream applications.

Although we generally are not regulated as a utility, federal, state, and local government statutes and regulations concerning electricity heavily influence the market for our product and services. These statutes and regulations, like the IRA, often relate to electricity pricing, transmission and distribution rates, net metering, incentives, taxation, competition with utilities and the interconnection of customer-owned electricity generation. We believe we are well positioned to capture incentives contained in the IRA and that its enactment is favorable to our business and future operations with our forthcoming battery module manufacturing as well as our contract manufacturing facility in Utah and our supply agreement for U.S. manufactured battery cells. However, as this legislation was recently adopted in August 2022 and applicable U.S. Department of Treasury and Internal Revenue Service guidelines were published in the third quarter of fiscal year 2023, we have not yet seen the impact these IRA related incentives may have on our business, operations and financial performance as we go forward and cannot guarantee we will realize anticipated benefits of incentives under the IRA. We are continuing to evaluate the overall impact and applicability of the IRA to our expected results of operations going forward.

Key Components of Our Results of Operations

The following discussion describes certain line items in our condensed consolidated statements of operations and comprehensive loss.

Total Revenue

We generate revenue from energy storage products and solutions, service agreements with customers to provide operational services related to battery-based energy storage products, and from digital application contracts. Fluence enters into contracts with utility companies, developers, and commercial and industrial customers. We derive the majority of our revenue from selling energy storage products and solutions. When we sell a battery-based energy storage product and solution, we enter into a contract with our customers covering the price, specifications, delivery dates and warranty for the products being purchased, among other things. The manner in which a solution is provided to a customer may vary; not all solutions may require Fluence to procure batteries on behalf of a customer. A solution may only require logistics, design, installation and/or commission services depending on customer requirements. We also generate revenue by providing consulting services to AES whereby Fluence has agreed to advise, and in some cases provide support to AES, on procurement, logistics, design, safety, and commissioning of certain of their projects.

Our revenue is affected by changes in the price, volume, and mix of products and services purchased by our customers, which is driven by the demand for our products, geographic mix of our customers, strength of competitors’ product offerings, and availability of government incentives to the end-users of our products. The Company recognizes revenue over time for our energy storage products and solutions as we transfer control of our product to the customer. This transfer of control to the customer is supported by clauses in the contracts that provide enforceable rights to payment of the transaction price associated with work performed to date for products that do not have an alternative use to the Company and/or as the project is built and control transfers depending on the contract terms.

Our revenue growth is dependent on continued growth in the amount of battery-based energy storage products and solutions projects constructed each year and our ability to increase our share of demand in the geographic regions where we currently compete and plan to compete in the future as well as our ability to continue to develop and commercialize new and innovative products that address the changing technology and performance requirements of our customers.

Cost of Goods and Services

Cost of goods and services consists primarily of product costs, including purchased materials and supplies, as well as costs related to shipping, customer support, product warranty, and personnel. Personnel costs in cost of goods and services includes both direct labor costs as well as costs attributable to any individuals whose activities relate to the transformation of raw materials or component parts into finished goods or the transportation of materials to the customer.

Our product costs are affected by the underlying cost of raw materials, including steel and aluminum supply costs, including inverters, casings, fuses, and cable; technological innovation; economies of scale resulting in lower supply costs; and improvements in production processes and automation. We do not currently hedge against changes in the price of raw materials as we do not purchase raw materials; instead, we buy the components of energy storage products from our suppliers and we rely on our suppliers to hedge the underlying raw materials. We generally expect the ratio of cost of

Table of Contents

goods and services to revenue to decrease as sales volumes increase due to economies of scale, however, some of these costs, primarily personnel-related costs, are not directly affected by sales volume.

Gross Profit and Gross Profit Margin

Gross profit and gross profit margin may vary from quarter to quarter and is primarily affected by our sales volume, product prices, product costs, product mix, customer mix, geographical mix, shipping costs, and warranty costs.

Operating Expenses

Operating expenses consist of research and development, sales and marketing and general and administrative expenses as well as depreciation and amortization. Personnel-related expenses are the most significant component of our operating expenses and include salaries, stock-based compensation, and employee benefits. We expect to invest in additional resources to support our growth which will increase our operating expenses in the near future.

Research and Development Expenses

Research and development expenses consist of personnel-related costs across our global research and development (R&D) centers for engineers engaged in the design and development and testing of our integrated products and technologies. Engineering competencies include data science, machine learning, software development, network and cyber security, battery systems engineering, industrial controls, UI / UX, mechanical design, power systems engineering, certification, and more. R&D expenses also support three product testing labs located across the globe, including a system-level testing facility in Pennsylvania that is used for quality assurance and the rapid iteration, testing, and launching of new Fluence energy storage technology and products. We are standing up an additional Hardware in the Loop testing facility which is co-located with our technical team in Bangalore, India. We expect R&D expenses to generally increase in future periods to support our growth and as we continue to invest in research and development activities that are necessary to achieve our technology and product roadmap goals. These expenses may vary from period to period as a percentage of revenue, depending primarily upon when we choose to make more significant investments.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of personnel-related expenses, including salaries, stock-based compensation, and employee benefits. We have and intend to continue to expand our sales presence and marketing efforts to additional countries in the future.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related expenses, including salaries, stock-based compensation, and employee benefits, for our executives, finance, human resources, information technology, engineering and legal organizations that do not relate directly to the sales or research and development functions, as well as travel expenses, facilities costs, bad debt expense, and fees for professional services. Professional services consist of audit, legal, tax, insurance, information technology, and other costs.

Depreciation and Amortization

Depreciation consists of costs associated with property, plant, and equipment (“PP&E”) and amortization of intangibles consisting of patents, licenses, and developed technology over their expected period of use. We expect that as we increase both our revenues and the number of our general and administrative personnel, we will invest in additional PP&E to support our growth resulting in additional depreciation and amortization.

Interest Income, net

Interest income, net consists of interest income net of interest expense. Interest income consists of interest earned on cash deposits and interest on customer notes receivables. Interest expense consists primarily of interest on borrowings against notes receivable pledged as collateral, unused line fees related to the revolving credit facility (the “Revolver”) pursuant to a credit agreement, dated November 1, 2021, by and among Fluence Energy, LLC, as the borrower, Fluence Energy, Inc., as a parent guarantor, the subsidiary guarantors party thereto, the lenders party thereto and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent (the “Revolving Credit Agreement”), which was terminated upon

Table of Contents

repayment in full of all obligations under the Revolver, effective November 22, 2023, and amortization of debt issuance costs. Interest income, net also consists of unused line and commitment fees on the ABL Facility that was entered into on November 22, 2023.

Other Income, Net

Other income, net primarily consists of income or expense from foreign currency exchange gains and losses on monetary assets and liabilities.

Tax Benefit

We are subject to U.S. federal and state income taxes with respect to our allocable share of any taxable income or loss of Fluence Energy, LLC, and are taxed at the prevailing corporate tax rates. We are also subject to foreign income taxes with respect to our foreign subsidiaries and our expectations are valuation allowances will be recorded in certain tax jurisdictions. In addition to tax expenses, we also will incur expenses related to our operations, as well as payments under the Tax Receivable Agreement, which we expect could be significant over time. We will receive a portion of any distributions made by Fluence Energy, LLC. Any cash received from such distributions from our subsidiaries will be first used by us to satisfy any tax liability and then to make payments required under the Tax Receivable Agreement.

Key Operating Metrics

The following tables present our key operating metrics as of December 31, 2023 and September 30, 2023, and order intake for the three months ended December 31, 2023 and 2022. The tables below present the metrics in either Gigawatts

Table of Contents

(GW) or Gigawatt hours (GWh). Our key operating metrics focus on project milestones to measure our performance and designate each project as either “deployed”, “assets under management”, “contracted” or “pipeline”.

Deployed

Deployed represents cumulative energy storage products and solutions that have achieved substantial completion and are not decommissioned. Deployed is monitored by management to measure our performance towards achieving project milestones.

Assets Under Management

Assets under management for service contracts represents our long-term service contracts with customers associated with our completed energy storage system products and solutions. We start providing maintenance, monitoring, or other operational services after the storage product projects are completed. In some cases, services may be commenced for energy storage solutions prior to achievement of substantial completion. This is not limited to energy storage solutions delivered by Fluence. Assets under management for digital software represents contracts signed and active (post go live). Assets under management serves as an indicator of expected revenue from our customers and assists management in forecasting our expected financial performance.

Table of Contents

Contracted Backlog

For our energy storage products and solutions contracts, contracted backlog includes signed customer orders or contracts under execution prior to when substantial completion is achieved. For service contracts, contracted backlog includes signed service agreements associated with our storage product projects that have not been completed and the associated service has not started. For digital applications contracts, contracted backlog includes signed agreements where the associated subscription has not started.

Contracted/Order Intake

Contracted, which we use interchangeably with “Order Intake”, represents new energy storage product contracts, new service contracts and new digital contracts signed during each period presented. We define “Contracted” as a firm and binding purchase order, letter of award, change order or other signed contract (in each case an “Order”) from the customer that is received and accepted by Fluence. Our order intake is intended to convey the dollar amount and gigawatts (operating measure) contracted in the period presented. We believe that order intake provides useful information to investors and management because the order intake provides visibility into future revenue and enables evaluation of the effectiveness of the Company’s sales activity and the attractiveness of its offerings in the market.

Pipeline

Pipeline represents our uncontracted, potential revenue from energy storage products, service, and digital software contracts, which have a reasonable likelihood of contract execution within 24 months. Pipeline is an internal management metric that we construct from market information reported by our global sales force. Pipeline is monitored by management to understand the anticipated growth of our Company and our estimated future revenue related to customer contracts for our battery-based energy storage products and solutions, services and digital software.

We cannot guarantee that our contracted backlog or pipeline will result in actual revenue in the originally anticipated period or at all. Contracted backlog and pipeline may not generate margins equal to our historical operating results. We have only recently begun to track our contracted backlog and pipelines on a consistent basis as performance measures, and as a result, we do not have significant experience in determining the level of realization that we will achieve on these contracts. Our customers may experience project delays or cancel orders as a result of external market factors and economic or other factors beyond our control. If our contracted backlog and pipeline fail to result in revenue as anticipated or in a timely manner, we could experience a reduction in revenue, profitability, and liquidity.

Non-GAAP Financial Measures

This section contains references to certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Gross Profit, Adjusted Gross Profit Margin, and Free Cash Flow.

Adjusted EBITDA is calculated from the consolidated statements of operations using net income (loss) adjusted for (i) interest income, net, (ii) income taxes, (iii) depreciation and amortization, (iv) stock-based compensation, (v) other income or expenses and (vi) non-recurring income or expenses. Adjusted EBITDA may in the future also be adjusted for amounts impacting net income related to the Tax Receivable Agreement liability.

Adjusted Gross Profit is calculated using gross profit, adjusted to exclude (i) stock-based compensation expenses, (ii) amortization, (iii) certain other income or expenses, and (iv) non-recurring income or expenses. Adjusted Gross Profit Margin is calculated using Adjusted Gross Profit divided by total revenue.

Free Cash Flow is calculated from the consolidated statements of cash flows and is defined as net cash provided by (used in) operating activities, less purchase of property and equipment made in the period. We expect our Free Cash Flow to fluctuate in future periods as we invest in our business to support our plans for growth. Limitations on the use of Free Cash Flow include (i) it should not be inferred that the entire Free Cash Flow amount is available for discretionary expenditures (for example, cash is still required to satisfy other working capital needs, including short-term investment policy, restricted cash, and intangible assets); (ii) Free Cash Flow has limitations as an analytical tool, and it should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by operating activities; and (iii) this metric does not reflect our future contractual commitments.

These non-GAAP measures are intended as supplemental measures of performance and/or liquidity that are neither required by, nor presented in accordance with, GAAP. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under GAAP, can be used to better assess our performance from period to

Table of Contents

period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure.

These non-GAAP measures should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP and may not be comparable to similar measures presented by other entities. Readers are cautioned that these non-GAAP measures should not be construed as alternatives to other measures of financial performance calculated in accordance with GAAP. These non-GAAP measures and their reconciliation to GAAP financial measures are shown below.

The following tables present our non-GAAP measures for the periods indicated.

Total Revenue

Total revenue increased by $53.5 million, or 17%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase was mainly attributable to the expansion of sales of our battery-based energy storage products and solutions by $51.1 million. The expansion of sales of our battery-based energy storage products and solutions was primarily driven by increased volumes of Gen6 solutions sold in the Americas and APAC regions offset by (i) a decrease in volumes of Gen6 solutions sold in the EMEA region and (ii) non-recurring favorable impacts in the prior period due to price increase change orders issued during the period where the performance obligations were substantially satisfied in previous periods.

Costs of Goods and Services

Cost of goods and services increased by $29.2 million, or 10%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase in cost of goods and services was mainly attributable to the expansion of volume of Gen6 solutions sold in Americas and APAC regions, offset by a decrease in volume of Gen6 solutions sold in EMEA region. The increase in costs of goods and services was less than the percentage increase in revenue due to an improvement in gross margins on newer Gen6 solutions projects offset by non-recurring favorable impact of a settlement of contractual claims with our largest battery module vendor of $19.5 million in December 2022.

Gross Profit and Gross Profit Margin

Gross profit increased by $24.3 million, or 202%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase in gross profit is primarily due to improvement in gross margins on

Table of Contents

the newer Gen6 solutions projects in the current period offset by non-recurring favorable impacts in the prior period due to (i) a settlement of contractual claims with our largest battery module vendor in December 2022 for $19.5 million and (ii) $10.1 million for price increase change orders issued during the period where the performance obligations were substantially satisfied in previous periods.

Research and Development Expenses

Research and development expenses decreased by $3.7 million, or 19%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The decrease was primarily attributable to (i) a $1.6 million reduction in stock-based compensation expense, and (ii) a $1.3 million decrease in third party services.

Sales and Marketing Expenses

Sales and marketing expenses increased by $1.9 million, or 22%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase was primarily attributable to (i) an increase in IT cost allocations of $1.4 million to support our growth and (ii) spend on conferences, sponsorships and other related advertising of $0.4 million.

General and Administrative Expenses

General and administrative expenses increased by $6.5 million, or 21%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase was primarily attributable to (i) an increase in personnel-related costs of $7.1 million due to higher headcount to support our growth and (ii) a $2.0 million increase in information technology licenses and consulting services related to implementation of new systems to support our growth offset by a reduction in consulting services of $2.6 million, which were mostly indirectly related to the restructuring plan from fiscal year 2023 that was substantially completed.

Depreciation and Amortization

Depreciation and amortization increased by $0.1 million, or 2%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The depreciation increase is primarily attributed to an increase in equipment capitalized.

Interest Income, Net

Interest income, net increased by $1.3 million, or 204%, in the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase was primarily attributable to an increase in interest income of $1.6 million due to higher interest rates on cash deposits and investments offset by additional interest expense of $0.4 million related to writing off a portion of capitalized debt issuance costs related to termination of the Revolver.

Other Income, Net

Other income, net decreased by $10.0 million, or 89%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The decrease in other income, net was primarily attributable to $9.2 million decrease in favorable foreign currency exchange gains for monetary assets and liabilities period over period.

Income Tax Benefit

Income tax benefit increased by $0.6 million, or 101%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The increase in tax benefit is primarily due to a change in the mix of pre-tax losses globally in the three months ended December 31, 2023.

Net Loss

Net loss decreased by $11.6 million, or 31%, for the three months ended December 31, 2023, compared to the three months ended December 31, 2022. The decrease is primarily attributable to (i) increase in “gross profit”, (ii) decrease in “research and development expenses” and (iii) increase in “interest income, net” as described above. This was partially offset by (i) decrease in “other income, net” and (ii) an increase in “general and administrative expenses” as described above.

Liquidity and Capital Resources

Since inception and through December 31, 2023, our principal sources of liquidity were the proceeds from our IPO, our cash and cash equivalents, short-term borrowings, borrowings available under the Revolver, borrowings available under the ABL Credit Facility, supply chain financing, capital contributions from AES Grid Stability and Siemens Industry, proceeds from the investment and borrowings against note receivables.

We believe the proceeds received from our IPO, cash flows from operations, borrowings against notes receivable and borrowings available under the ABL Credit Facility will be sufficient to meet our expense and capital requirements for at least the next 12 months following the filing of this Report.

Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth, the timing and extent of our growth initiatives and our introduction of new products, services, and digital application offerings, and overall economic conditions. To the extent that current and anticipated future sources of liquidity are insufficient to fund our future business activities and cash requirements, we may be required to seek additional equity or debt financing. The sale of additional equity would result in additional dilutions to our stockholders. The incurrence of additional debt financing would result in debt service obligations and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued innovation, we may not be able to compete successfully, which would harm our business, operations and financial condition.

On November 1, 2021, upon the closing of our IPO, we received net proceeds of $935.8 million, after deducting underwriting discounts and offering expenses payable by the Company. The net proceeds from the IPO were used to purchase 35,650,000 newly issued LLC Interests directly from Fluence Energy, LLC at a price per unit equal to the IPO price per share of Class A common stock less the underwriting discount and estimated offering expenses payable by us. Fluence Energy, LLC used the net proceeds from the sale of LLC Interests to Fluence Energy, Inc. to repay all outstanding borrowings relating to a line of credit and promissory notes. The remainder of the proceeds has been used for working capital and other general corporate purposes.

We have provided certain of our suppliers with access to a supply chain financing program through a third-party financing institution (the “SCF Bank”). This program allows us to seek extended payment terms with our suppliers and allows our suppliers to monetize their receivables prior to the payment due date, subject to a discount. Once a supplier elects to participate in the program and reaches an agreement with the SCF Bank, the supplier elects which individual invoices to sell to the SCF Bank. We then pay the SCF Bank on the invoice due date. We have no economic interest in a supplier’s decision to sell a receivable to the SCF Bank. The agreements between our suppliers and the SCF Bank are solely at their discretion and are negotiated directly between them. Our suppliers’ ability to continue using such agreements is primarily dependent upon the strength of our financial condition and guarantees issued by AES and Siemens. As of December 31, 2023, AES and Siemens issued guarantees of $50.0 million each, for a total of $100.0 million, to SCF Bank on our behalf.

As of December 31, 2023, three suppliers were actively participating in the supply chain financing program, and we had $45.9 million of payables outstanding subject to the program. All outstanding payments owed under the program are recorded within “Accounts payable” on the condensed consolidated balance sheets.

On August 11, 2023, we filed an automatic shelf registration statement on Form S-3 with the SEC (the “Form S-3”) which became effective upon filing and will remain effective through August 11, 2026. The Form S-3 allows us to offer and sell from time-to-time Class A common stock, preferred stock, depository shares, debt securities, warrants, purchase contracts or units comprised of any combination of these securities for our own account and allows certain selling stockholders to offer and sell 135,666,665 shares of Class A common stock in one or more offerings.

The Form S-3 is intended to provide us flexibility to conduct registered sales of our securities, subject to market conditions and our future capital needs. The terms of any future offering under the Form S-3 will be established at the time of such offering and will be described in a prospectus supplement filed with the SEC prior to the completion of any such offering.

Revolving Credit Facility

We entered into a Revolving Credit Agreement for a Revolving Credit Facility (the “Revolver”) on November 1, 2021, by and among Fluence Energy, LLC, as the borrower, Fluence Energy Inc., as a parent guarantor, the subsidiary guarantors party thereto, the lenders party thereto and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent. The aggregate amount of commitments was $200.0 million. The Revolver was originally scheduled to mature on November 1, 2025. The Revolving Credit Agreement was terminated effective November 22, 2023, in conjunction with the entry into the new ABL Credit Agreement (as further described below) in connection with which the Company prepaid all amounts outstanding under the Revolver and terminated all Commitments (as defined in the Revolving Credit Agreement) thereunder. No penalties were required to be paid as a result of the termination.

The Revolver was secured by (i) a first priority pledge of the equity securities of Fluence Energy, LLC and its subsidiaries and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, LLC, the parent guarantor and each subsidiary guarantor party thereto, in each case, subject to customary exceptions and limitations. On May 19, 2023, the Revolving Credit Agreement was amended to replace Adjusted LIBOR with Adjusted Term SOFR as the applicable benchmark interest rate with respect to certain classes of loans.

The Revolver bore interest at either (i) the Adjusted SOFR Rate (each as defined in the Revolving Credit Agreement) plus 3.0 % or (ii) the Alternate Base Rate (as defined in the Revolving Credit Agreement) plus 2.0% (subject to customary LIBOR replacement provisions and alternative benchmark rates including customary spread adjustments with respect to borrowings in foreign currency), at the option of Fluence Energy, LLC. Fluence Energy, LLC was required to pay to the lenders a commitment fee of 0.55 % per annum on the average daily unused portion of the revolving commitments through maturity, which was originally scheduled to be the four-year anniversary of the closing date of the Revolver. The Revolver also provided for up to $200.0 million in letter of credit issuances, which required customary issuance and administration fees, as well as a fronting fee payable to each issuer thereof and a letter of credit participation fee of 2.75% per annum payable to the lenders.

The Revolving Credit Agreement contained covenants that, among other things, restricted our ability to incur additional indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; make dividends, distributions, or other restricted payments; and engage in affiliate transactions. The terms of the Revolving Credit Agreement limited our ability to make certain payments, including dividends and distributions on Fluence Energy, LLC’s equity, Fluence Energy, Inc.’s equity and other restricted payments. Under the terms of the Revolving Credit Agreement, Fluence Energy, LLC and its subsidiaries were limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions, including among others (i) the ability to make investments of up to the greater of (a) $10,500,000 and (b) 1.5% of the consolidated assets of Fluence Energy, Inc. and its subsidiaries, and (ii) the ability to issue dividends and make other Restricted Payments (as defined in the Revolving Credit Agreement) (a) if after giving pro forma effect to such dividend or other Restricted Payment the Total Liquidity (as defined in the Revolving Credit Agreement) of Fluence Energy, Inc. and its subsidiaries party to the Revolving Credit Agreement was at least $600,000,000, or (b) such dividend or other Restricted Payment was made to reimburse Fluence Energy, Inc. for certain tax distributions under the Fluence Energy LLC Agreement and certain payments under the Tax Receivable Agreement and certain operational expenses incurred in connection with the ownership and management of Fluence Energy, LLC. In addition, we were required to maintain (i) minimum liquidity and gross revenue requirements, in each case, until consolidated EBITDA reached $150.0 million for the most recent four fiscal quarters and we made an election, and (ii) thereafter, a maximum total leverage ratio and a minimum interest coverage ratio. Such covenants were tested on a quarterly basis.

Asset-Based Lending Facility

Borrowing availability under the ABL Facility is determined by a borrowing base calculation that is based on specified percentages of U.S. eligible inventory, net orderly liquidation value of most recent inventory appraisal, and U.S. eligible in-transit inventory, less the aggregate amount of any reserves. The ABL Credit Agreement provides for a full cash dominion period (a) if an event of default is occurring or (b) beginning on the date on which Excess Availability is less than the greater of (i) 12.5% of the Line Cap and (ii) if the borrowing base then in effect is (A) less than $200.0 million, $25.0 million and (B) greater than or equal to $200.0 million, $50.0 million. Line Cap is defined under the ABL Facility as the lesser of the total commitments of the ABL Lenders and the borrowing base. Excess Availability is defined under the ABL Facility as an amount equal to (a) the lesser of (i) the total commitments of all lenders and (ii) the borrowing base, minus (b) total revolving extensions of credit then outstanding at anytime.

The ABL Credit Agreement sets forth that (i) loans comprising each ABR Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Alternate Base Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability (as defined in the ABL Credit Agreement) during the applicable determination period, (ii) loans comprising each Canadian Prime Loan Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Canadian Prime Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability during the applicable determination period, and (iii) the loans comprising each Term Benchmark Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Adjusted Term SOFR Rate, the Adjusted EURIBOR Rate or Adjusted Term CORRA (each as defined in the ABL Credit Agreement), as applicable, plus an additional margin ranging from 2.00% to 2.50%, depending on the Average Excess Availability during the applicable determination period, in each instance subject to customary benchmark replacement provisions including, but not limited to, alternative benchmark rates, customary spread adjustments with respect to borrowings in foreign currencies and benchmark replacement conforming changes. Fluence Energy, LLC is required to pay to the ABL Lenders a commitment fee on the average daily unused portion of the commitments through maturity, which shall accrue at the rate of (a) until the last day of the first full calendar quarter following the closing of the ABL Facility, 0.450% per annum, and (b) thereafter, 0.450% per annum if average revolving loan utilization is less than or equal to 50% and 0.375% per annum if average revolving loan utilization is greater than 50%. The ABL Facility also provides for a letter of credit sublimit in the amount of $200.0 million, if certain conditions are met. Each letter of credit issuance will be conditioned upon, among other conditions, the payment of certain customary issuance and administration fees, as well as payment of a fronting fee to each issuer thereof and payment of a letter of credit participation fee payable to the ABL Lenders.

Table of Contents

The ABL Credit Agreement contains customary covenants for this type of financing, including, but not limited to, covenants that restrict our ability to incur indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; pay dividends, make distributions or other restricted payments; and engage in affiliate transactions. The ABL Credit Agreement limits our ability to make certain payments, including dividends and distributions on Fluence Energy, LLC’s equity, the Company’s equity and other restricted payments. Under the terms of the ABL Credit Agreement, Fluence Energy, LLC and its subsidiaries are currently limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions. In addition, if certain payment conditions under the ABL Credit Agreement are satisfied, including the satisfaction of a minimum excess availability requirement, then additional specified transactions may be made by the Company and its subsidiaries. The Company agreed that it will not, and its subsidiaries will not, permit Total Liquidity (as defined in the ABL Credit Agreement) at any time to be less than the greater of (i) 20% of the Line Cap then in effect and (ii) $64.0 million, and the Company agreed that it will not, and its subsidiaries will not, permit Excess Availability to be less than the greater of (i) $15.0 million and (ii) 10% of the Line Cap then in effect. Such covenants will be tested on a quarterly basis and upon certain restricted payments, the incurrence of indebtedness, certain dispositions and other Specified Transactions (as defined in the ABL Credit Agreement). As of December 31, 2023, we were in compliance with all such covenants or maintained availability above such covenant triggers.

As of December 31, 2023, we had no borrowings under the ABL Facility and $0 of letters of credit outstanding, and availability under the facility of $75.2 million.

Borrowings Against Note Receivable - Pledged as Collateral

In December 2022, we transferred $24.3 million in customer receivables to Standard Chartered Bank (“SCB”) in the Philippines for proceeds of $21.1 million. The receivables all related to our largest customer in that country. The underlying receivables transferred were previously aggregated into a long term note, with interest, and which has a maturity date of September 30, 2024. In April 2023, we aggregated and transferred an additional $30.9 million in receivables into a second long term note with the same customer to SCB for proceeds of $27.0 million, upon substantially similar terms as the December 2022 transfer and with a maturity date of December 27, 2024. These transactions are treated as secured borrowings as we did not transfer the entire note receivables due from the customer to SCB. We continue to receive quarterly interest income from the customer, while SCB is responsible for collecting payments on the principal balances which represent the initial receivable balances from the customer. We have no other continuing involvement or exposure related to the underlying receivables. For the three months ended December 31, 2023, the Company recorded net interest income of $0.1 million, which represents the aggregate of $1.2 million in interest income and $1.1 million in interest expense recorded in “Interest income, net.”

Credit Support and Reimbursement Agreement

We are party to an Amended and Restated Credit Support and Reimbursement Agreement with AES and Siemens Industry whereby they may, from time to time, agree to furnish credit support to us in the form of direct issuances of credit support to our lenders or other beneficiaries or through their lenders’ provision of letters of credit to backstop our own facilities or obligations. Pursuant to the Amended and Restated Credit Support and Reimbursement Agreement, if AES or Siemens Industry agree to provide a particular credit support (which they are permitted to grant or deny in their sole discretion), they are entitled to receipt of a credit support fee and reimbursement for all amounts paid to our lenders or other counterparties, payable upon demand. The Amended and Restated Credit Support and Reimbursement Agreement initially expires on June 9, 2025 (the “initial expiration date”), and will automatically and indefinitely continue after such date; after such initial expiration date, either AES or Siemens Industry is permitted to terminate the agreement upon six months prior notice. Any credit support under the Credit Support and Reimbursement Agreement will remain in effect after any such termination until such credit support has been replaced by the Company.

Commitments, Guarantees, Letter of Credits, Surety Bonds, Off-Balance Sheet Arrangements

As of December 31, 2023, the Company had outstanding bank guarantees, parent guarantees, letters of credit, and surety bonds issued as performance security arrangements for a large number of customer projects. The Company has certain battery purchase obligations under a master supply agreement with a supplier. We are also party to both assurance and service-type warranties for various lengths of time. Refer to “Note 12 - Commitments and Contingencies” to our unaudited condensed financial statements included elsewhere in this Report for more information regarding our contingent obligations, including off-balance sheet arrangements, and legal contingencies.

Historical Cash Flows

The following table summarizes our cash flows from operating, investing, and financing activities for the periods presented.


	Three Months Ended December 31,				Change		Change %
($ in thousands)	2023		2022
Net cash provided by (used in) operating activities	$	19,363	$	(88,898)	$	108,261	121.8	%
Net cash used in investing activities	$	(2,596)	$	(6,331)	$	3,735	(59.0)	%
Net cash provided by (used in) financing activities	$	(6,359)	$	23,252	$	(29,611)	(127.3)	%

Net cash flows provided by operating activities of $19.4 million for the three months ended December 31, 2023, were primarily driven by increases in (i) payables and deferred revenue with related parties of $148.4 million and (ii) accounts payable of $255.3 million offset by an increase in inventory, impacting cash flow negatively by $336.4 million and net loss of $25.6 million. The increase in payables and deferred revenues with related parties and inventory is primarily driven by timing of payments received and the timing of execution of certain contracts, as we are expecting higher revenues in the last three fiscal quarters of 2024.

Net cash flows used in operating activities of $88.9 million for the three months ended December 31, 2022, were primarily due to (i) net loss of $37.2 million, (ii) purchases of inventory of $430.5 million, (iii) offset by an increase in accounts payable of $200.7 million and an (iv) increase in third party deferred revenue of $196.0 million. We had built up our inventory balance at the end of fiscal year 2022 and continued to do so for the first three months ended December 31, 2022, as a risk mitigation strategy to provide the Company with supply chain assurance. The inventory build up was partially funded by milestone payments from customers driving up our deferred revenue balance and due to timing of payments to our vendors, which caused the increase in our accounts payable balances.

Net cash flows used in investing activities were $2.6 million for the three months ended December 31, 2023, which included $1.5 million purchases of property and equipment, and capital expenditures on internal-use software and software to be sold of $1.1 million.

Net cash flows used in investing activities were $6.4 million for the three months ended December 31, 2022, which included $2.5 million purchases of property and equipment and $5.0 million investment in joint venture offset by proceeds on short term investments.

Net cash flows used in financing activities were approximately $6.4 million for the three months ended December 31, 2023. The net cash flows used in financing activities were primarily related to $3.6 million in payments related to debt issuances costs for the ABL Facility and $3.9 million in payments for a previously acquired company (Nispera) offset by $1.1 million of proceeds from the exercise of stock options.

Net cash flows provided by financing activities were $23.3 million for the three months ended December 31, 2022. The net cash flows provided by financing activities were primarily driven by $21.1 million of proceeds from secured borrowings against notes receivable and $2.4 million of proceeds from the exercise of stock options, offset by $0.3 million related to repurchase of Class A common stock placed in treasury.

Tax Receivable Agreement

In connection with the IPO, we entered into the Tax Receivable Agreement with Fluence Energy, LLC and Siemens Industry and AES Grid Stability (together, the “Founders”). Under the Tax Receivable Agreement, we are required to make cash payments to the Founders equal to 85% of the tax benefits, if any, that we actually realize, or in certain circumstances are deemed to realize, as a result of (1) the increases in our share of the tax basis of assets of Fluence Energy, LLC and its subsidiaries resulting from any redemptions or exchanges of LLC Interests from the Founders and certain distributions (or deemed distributions) by Fluence Energy, LLC; and (2) certain other tax benefits arising from payments under the Tax Receivable Agreement. The payment obligation under the Tax Receivable Agreement is an obligation of Fluence Energy, Inc. and not of Fluence Energy, LLC. We expect to use distributions from Fluence Energy, LLC to fund any payments that we will be required to make under the Tax Receivable Agreement. To the extent we are unable to make timely payments under the Tax Receivable Agreement for any reason, such payments generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement.

Table of Contents

Fluence Energy, Inc. expects to benefit from the remaining 15% of cash tax benefits, if any, it realizes from such tax benefits. For purposes of the Tax Receivable Agreement, the cash tax benefits will be computed by comparing the actual income tax liability of Fluence Energy, Inc. to the amount of such taxes that Fluence Energy, Inc. would have been required to pay had there been no such tax basis adjustments of the assets of Fluence Energy, LLC or its subsidiaries as a result of redemptions or exchanges and had Fluence Energy, Inc. not entered into the Tax Receivable Agreement.

On June 30, 2022, Siemens Industry, Inc. exercised its redemption right pursuant to the terms of LLC Agreement with respect to its entire holding of 58,586,695 LLC Interests of Fluence Energy, LLC, together with the corresponding cancellation of an equivalent number of shares of Class B-1 common stock of Fluence Energy, Inc., par value $0.00001 per share.

On December 8, 2023, AES Grid Stability exercised its redemption right pursuant to the terms of LLC Agreement with respect to 7,087,500 LLC Interests of Fluence Energy, LLC, together with the corresponding cancellation of an equivalent number of shares of Class B-1 common stock of Fluence Energy, Inc., par value $0.00001 per share.

The redemptions resulted in increases in the tax basis of the assets of Fluence Energy, LLC and certain of its subsidiaries. The increases in tax basis and tax basis adjustments increases (for tax purposes) the depreciation and amortization deductions available to Fluence Energy, Inc. and, therefore, may reduce the amount of U.S. federal, state, and local tax that Fluence Energy, Inc. would otherwise be required to pay in the future, although the IRS may challenge all or part of the validity of that tax basis, and a court could sustain such a challenge.

As a result of the tax basis adjustment of the assets of Fluence Energy, LLC and its subsidiaries upon the redemptions and our possible utilization of certain tax attributes, the payments that we may make under the Tax Receivable Agreement will be substantial. The redemptions will result in future tax savings of $138.6 million. AES and Siemens will be entitled to receive payments under the Tax Receivable Agreement equaling 85% of such amount, or $117.8 million; assuming, among other factors, (i) we will have sufficient taxable income to fully utilize the tax benefits; (ii) Fluence Energy, LLC is able to fully depreciate or amortize its assets; and (iii) there are no material changes in applicable tax law. The payments under the Tax Receivable Agreement are not conditioned upon continued ownership of us by the Founders. Although the timing and extent of future payments could vary significantly under the Tax Receivable Agreement, we anticipate funding payments from the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements.

We have determined it is not probable payments under the Tax Receivable Agreement would be made, given the projected inability to fully utilize the related tax benefits over the term of the agreement. Therefore, the Company has not recognized the liability. Should we determine that the Tax Receivable Agreement payment is probable, a corresponding liability will be recorded and as a result, our future results of operations and earnings could be impacted as a result of these matters.

Critical Accounting Policies and Use of Estimates

Our financial statements have been prepared in accordance with U.S. GAAP. In the preparation of these financial statements, we consider an accounting judgment, estimate or assumption to be critical when (1) the estimate or assumption is complex in nature or requires a high degree of judgment and (2) the use of different judgments, estimates, and assumptions could have a material impact on the consolidated financial statements.

During the three months ended December 31, 2023, there were no significant changes in application of our critical accounting policies or estimation procedures from those described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Use of Estimates” in our 2023 Annual Report and the notes to the audited consolidated financial statements appearing elsewhere in the 2023 Annual Report.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes with respect to our exposure to market risk as disclosed in Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” of our 2023 Annual Report.

Table of Contents

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance of achieving the objective that information in our Securities Exchange Act of 1934, as amended (the “Exchange Act”) reports is recorded, processed, summarized and reported within the time periods specified and pursuant to the requirements of the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2023, the end of the period covered by this Report. Based upon that evaluation, and as a result of the material weaknesses described below, management concluded that, as of December 31, 2023, our disclosure controls and procedures were not effective at the reasonable assurance level.

Material Weaknesses and Remediation Measures

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

As of December 31, 2023, a material weakness in the internal control related to the Company’s estimate at completion (“EAC”) process, which is used in the Company’s percentage of completion (“POC”) accounting has not been remediated.

We assessed the material weakness as not remediated as the EAC controls did not consistently operate for a sufficient period of time. Management has enhanced the process and training to control owners during the first quarter of fiscal year 2024. However, additional time is required to ensure the successful implementation of the remediation efforts over a sustained period of time before management can conclude that the material weakness has been remediated.

The actions that we are taking are subject to ongoing senior management review, as well as Audit Committee oversight. We are committed to maintaining a strong internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the material weakness are remediated as soon as possible; we believe our efforts will enable us to successfully remediate our material weakness in fiscal year 2024 however, we cannot provide assurance as to when our further remediation measures will be complete. We will consider the material weakness remediated after the applicable controls operate for a sufficient period of time, and management has concluded, through testing, that the controls are operating effectively.

Changes in Internal Control over Financial Reporting

Other than the changes to our internal control over financial reporting described in “Material Weaknesses and Remediation Measures” above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

From time to time, we may be involved in litigation relating to claims that arise out of our operations and business that cover a wide range of matters, including, among others, intellectual property matters, contract disputes, insurance and property damage claims, employment claims, personal injury claims, product liability claims, environmental claims and warranty claims. Currently, there are no claims or proceedings against us that we believe will have a material adverse effect on our business, financial condition, results of operations or cash flows. However, the results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, we may incur significant costs and experience a diversion of management resources as a result of claims and litigation.

For a description of our material pending legal contingencies, please see “Note 12 - Commitments and Contingencies”, to the unaudited condensed consolidated financial statements included elsewhere in this Report.

MASTER ASSIGNMENT AND ASSUMPTION
AND ISSUING BANK JOINDER

This Master Assignment and Assumption and Issuing Bank Joinder (this “Assignment and Assumption”) is dated as of the Effective Date set forth below and is entered into by and between each of the parties listed on Annex II hereto as an Assignor (each, an “Assignor” and collectively, the “Assignors”) and CITIBANK, N.A. (the “Assignee”). Capitalized terms used but not defined herein shall have the meanings given to them in the Syndicated Facility Agreement identified below (as amended, restated, amended and restated, supplemented, extended and/or otherwise modified from time to time, the “Credit Agreement”), receipt of a copy of which is hereby acknowledged by the Assignee. The Standard Terms and Conditions set forth in Annex I attached hereto are hereby agreed to and incorporated herein by reference and made a part of this Assignment and Assumption as if set forth herein in full.

For an agreed consideration, each Assignor hereby irrevocably sells and assigns to the Assignee, and the Assignee hereby irrevocably purchases and assumes from such Assignor, subject to and in accordance with the Standard Terms and Conditions and the Credit Agreement, as of the Effective Date set forth below (i) all of such Assignor’s rights and obligations in its capacity as a Lender under the Credit Agreement and any other documents or instruments delivered pursuant thereto to the extent related to the amount and percentage interest identified on Annex II hereto of all of such outstanding rights and obligations of such Assignor under the facility identified below (including any letters of credit included in the facility) and (ii) to the extent permitted to be assigned under applicable law, all claims, suits, causes of action and any other right of such Assignor (in its capacity as a Lender) against any Person, whether known or unknown, arising under or in connection with the Credit Agreement, any other documents or instruments delivered pursuant thereto or the loan transactions governed thereby or in any way based on or related to any of the foregoing, including contract claims, tort claims, malpractice claims, statutory claims and all other claims at law or in equity related to the rights and obligations sold and assigned pursuant to clause (i) above (the rights and obligations sold and assigned pursuant to clauses (i) and (ii) above being referred to herein collectively as the “Assigned Interest”). Such sale and assignment is without recourse to any Assignor and, except as expressly provided in this Assignment and Assumption, without representation or warranty by any Assignor.


1.	Assignor:	Each Assignor listed on Annex II hereto
2.	Assignee:	Citibank, N.A.
3.	Parent Borrower:	Fluence Energy, LLC (the “Company”)
4.	Administrative Agent:	Barclays Bank PLC, as administrative agent under the Credit Agreement
5.	Syndicated Facility Agreement:	Syndicated Facility Agreement, dated as of November 22, 2023, among the Company, as Parent Borrower, the other Borrowers party thereto, Fluence Energy, Inc. (the “Parent”), as Parent, the other Guarantors party thereto, the Lenders party thereto and Barclays Bank PLC, as Administrative Agent.

On the Effective Date, each Assignor shall pay, or cause to be paid, to the Administrative Agent, for the account of the Assignee, an upfront fee in the amount set forth with respect to such Assignor on Annex II hereto (each, an “Upfront Fee”). The Upfront Fees shall be fully earned as of the date of execution of this Assignment and Assumption.

The Assignee hereby agrees, as of the Effective Date, to become bound as an Issuing Bank by the terms, conditions and other provisions of, and to assume all of the right, title and interest in and to, and liabilities and obligations under, the Credit Agreement as an Issuing Bank, with all attendant rights, duties and obligations stated therein, with the same force and effect as if originally named therein as a party and as if the Assignee executed the Credit Agreement as of the date thereof. The Assignee further agrees, as of the date first above written, that each reference in the Credit Agreement to an “Issuing Bank” shall also mean and be a reference to the Assignee in its capacity as an Issuing Bank. Notwithstanding anything herein or in the Credit Agreement to the contrary, the Assignee’s commitment to issue Letters of Credit shall equal $40,000,000 in the aggregate (the “Citibank Letter of Credit Sublimit”). For the avoidance of doubt, the Citibank Letter of Credit Sublimit is part of, and not in addition to, the aggregate $200,000,000 Letter of Credit sublimit for all Issuing Banks. Subject to the terms and conditions set forth in the Credit Agreement, from time to time during the Availability Period, the Assignee, in its capacity as an Issuing Bank, may be requested by the Borrowers to issue Letters of Credit denominated in Dollars, Australian Dollars, Canadian Dollars, Euros or Pounds Sterling.

The parties to this Assignment and Assumption (including each Assignee in its capacity as a Lender and a Lender directly affected thereby and collectively constituting Required Lenders) hereby agree that, from and after the Effective Date, (a) notwithstanding anything to the contrary contained in the definition of “Issuing Bank” under the Credit Agreement, each of Barclays Bank PLC, JPMorgan Chase Bank, N.A., Citibank, N.A. Goldman Sachs Bank USA and Morgan Stanley Senior Funding, Inc. shall constitute Issuing Banks for purposes of the

Credit Agreement and other Loan Documents, and (b) Schedule 2.01 of the Credit Agreement is amended by replacing the table set forth therein in its entirety with the table set forth in Annex III hereto.

The Administrative Agent waives the $3,500 processing and recordation fee required pursuant to Section 10.04(b)(ii)(C) of the Credit Agreement with respect to each assignment to be effected under this Assignment and Assumption.

a.Except as otherwise provided in this Section 6(a), you knowingly and voluntarily hereby release, to the fullest extent permitted by law, the Company and all of its past, present and/or future related entities, including but not limited to parents, divisions, affiliates and subsidiaries, and each current and former bonus, pension, welfare, or other benefit plans sponsored by any of the foregoing, and each of the respective officers, directors, members, stockholders, trustees, employees, agents, representatives, administrators, attorneys, insurers, fiduciaries, predecessors, successors and assigns of such entities and/or benefit plans, in their individual and/or representative capacities (hereinafter collectively referred to as the “Released Parties”), from any and all causes of action, suits, agreements, promises, damages, disputes, controversies, contentions, differences, judgments, claims and demands of any kind whatsoever (“Claims”) which you or your heirs, executors, administrators, successors and assigns ever had, now have or may have against the Released Parties, whether known or unknown to you, and whether asserted or unasserted, (i) by reason of your employment and/or cessation of employment with the Company, other than the Consideration in accordance with its terms, or (ii) that otherwise arose or is based on facts which occurred on or prior to the date that you sign this Release.

If your place or places of work with the Company has included California in granting the release herein, which includes claims which may be unknown to you at present, you acknowledge that you have read and understand Section 1542 of the California Civil Code: “A general release does not extend to claims which the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release, and that if known by him or her would have materially affected his or her settlement with the debtor or released party.” You hereby expressly waive and relinquish all rights and benefits under that section and any law of any jurisdiction of similar effect with respect to your release of any unknown or unsuspected claims herein.

Nothing in this Release shall interfere with or waive your right to enforce this Release in a court of competent jurisdiction or seek a judicial determination of the validity of the release of your rights under the Age Discrimination in Employment Act.

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.

7.You further acknowledge and agree that you will not, unless required by law, disclose to anyone other than members of the Fluence Legal department or the Fluence HR department any information regarding the following:

Organization and Operations	Organization and Operations Fluence Energy, Inc., a Delaware corporation (the “Company”), was formed on June 21, 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. (“Siemens Industry”), an indirect subsidiary of Siemens AG (“Siemens”), and AES Grid Stability, LLC (“AES Grid Stability”), an indirect subsidiary of the AES Corporation (“AES”), and commenced operations on January 1, 2018. We refer to Siemens Industry and AES Grid Stability as the “Founders” in this Quarterly Report on Form 10-Q (this “Report”). Upon the completion of our initial public offering (“IPO”) on November 1, 2021, Fluence Energy, Inc. became a holding company whose sole material assets are the limited liability company interests (the “LLC Interests”) in Fluence Energy, LLC. All of our business is conducted through Fluence Energy, LLC, together with its subsidiaries, and the financial results of Fluence Energy, LLC are consolidated in our financial statements. Fluence Energy, LLC is taxed as a partnership for federal income tax purposes and, as a result, its members, including Fluence Energy, Inc., pay income taxes with respect to their allocable shares of its net taxable income. As of December 31, 2023, Fluence Energy, LLC had subsidiaries operating in Germany, Australia, Philippines, Chile, the Netherlands, the United States, India, Singapore, United Kingdom, Canada, Taiwan, Ireland, and Switzerland. Except where the context clearly indicates otherwise, “Fluence,” “we,” “us,” “our” or the “Company” refers to Fluence Energy, Inc. and all of its direct and indirect subsidiaries, including Fluence Energy, LLC. When used in a historical context that is prior to the completion of the IPO, “we,” “us,” “our” or “the Company” refers to Fluence Energy, LLC and its subsidiaries. The Company’s fiscal year begins on October 1 and ends on September 30. References to “fiscal year 2022” and “fiscal year 2023” refer to the twelve months ended September 30, 2022 and September 30, 2023, respectively. The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The Company’s CODM reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one operating segment, which corresponds to one reportable segment. Siemens Industry Redemption On June 30, 2022, Siemens Industry exercised its redemption right pursuant to the terms of the Third Amended and Restated Limited Liability Company Agreement of Fluence Energy, LLC (the “LLC Agreement”) with respect to its entire holding of 58,586,695 LLC Interests of Fluence Energy, LLC, together with the corresponding cancellation of an equivalent number of shares of Class B-1 common stock of Fluence Energy, Inc. (the “Siemens Redemption”). The Company elected to settle the Siemens Redemption through the issuance of 58,586,695 shares of the Company’s Class A common stock. The Siemens Redemption settled on July 7, 2022. The Siemens Redemption increased the beneficial ownership interest of the Company in Fluence Energy, LLC to 66.08% as of June 30, 2022. The impact of the change in ownership interest did not result in a change in control. The Siemens Redemption has been accounted for as an equity transaction and the carrying amount of non-controlling interest has been adjusted. Refer to “Consolidated statements of changes in stockholders’ equity” included herein. Secondary Offering and AES Redemption On December 8, 2023, AES Grid Stability, Siemens Pension-Trust e.V. (“Siemens Pension Trust”), Qatar Holding LLC (“QHL” and together with AES Grid Stability and Siemens Pension Trust in such context, the “Selling Stockholders”) closed an underwritten public offering (the “Offering”) of 18,000,000 shares of Class A common stock of the Company by the Selling Stockholders. The Company did not sell any of its shares of Class A common stock in the Offering and the Company did not receive any of the proceeds from the Offering. Pursuant to the terms of the Company’s Registration Rights Agreement, dated as of November 1, 2021, by and among the Company and the Original Equity Owners (as defined therein), the Company paid $0.7 million in certain expenses of the Selling Stockholders related to the Offering, while the Selling Stockholders paid all applicable underwriting discounts and commissions. In conjunction with the Offering, AES Grid Stability exercised its redemption right pursuant to the terms of the LLC Agreement with respect to 7,087,500 LLC Interests held by AES Grid Stability, together with the corresponding cancellation of an equivalent number of shares of Class B-1 common stock of the Company (the “AES Redemption”).

All of the 7,087,500 shares issued to AES Grid Stability in connection with the AES Redemption were sold in the Offering. The AES Redemption increased the beneficial ownership interest of the Company in Fluence Energy, LLC to 71.12% as of December 8, 2023. The impact of the change in ownership interest did not result in a change in control. The AES Redemption has been accounted for as an equity transaction and the carrying amount of the non-controlling interest has been adjusted.

The Revolver was secured by a (i) first priority pledge of the equity securities of Fluence Energy, LLC and its subsidiaries and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, LLC, the parent guarantor and each subsidiary guarantor party thereto, in each case, subject to customary exceptions and limitations. The initial aggregate amount of commitments was $190.0 million from the lenders party thereto including JP Morgan Chase Bank, N.A., Morgan Stanley Senior Funding, Inc., Bank of America, N.A., Barclays Bank PLC, and five other banks. On June 30, 2022, the Company increased the revolving commitment available under the Revolver by $10.0 million to an aggregate of $200.0 million with the addition of UBS AG, Stamford Branch as an additional lender under the Revolver. On May 19, 2023, the Credit Agreement was amended to replace Adjusted LIBOR with Adjusted Term SOFR as the applicable benchmark interest rate with respect to certain classes of loans. The Revolver was originally scheduled to mature on November 1, 2025. The Revolving Credit Agreement was terminated effective November 22, 2023, in conjunction with the entry into the new ABL Credit Agreement (as further described below). The Revolver bore interest at either (i) the Adjusted SOFR Rate (as defined in the Revolving Credit Agreement) plus 3.0% or (ii) the Alternate Base Rate (as defined in the Revolving Credit Agreement) plus 2.0% (subject to customary LIBOR replacement provisions and alternative benchmark rates including customary spread adjustments with respect to borrowings in foreign currency), at the option of Fluence Energy, LLC. Fluence Energy, LLC was required to pay to the lenders a commitment fee of 0.55% per annum on the average daily unused portion of the revolving commitments through maturity. The Revolver also provided for up to $200.0 million in letter of credit issuances, which required customary issuance and administration fees, as well as a fronting fee payable to each issuer thereof and a letter of credit participation fee of 2.75% per annum payable to the lenders. The Revolving Credit Agreement contained covenants that, among other things, restricted our ability to incur additional indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; make dividends, distributions, or other restricted payments; and engage in affiliate transactions. Under the terms of the Revolving Credit Agreement, Fluence Energy, LLC and its subsidiaries were limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions, including among others (i) the ability to make investments of up to the greater of (a) $10,500,000 and (b) 1.5% of the consolidated assets of Fluence Energy, Inc. and its subsidiaries, and (ii) the ability to issue dividends and make other restricted payments (a) if after giving pro forma effect to such dividend or other restricted payment the Total Liquidity (as defined in the Revolving Credit Agreement) of Fluence Energy, Inc. and its subsidiaries party to the Revolving Credit Agreement was at least $600,000,000, or (b) such dividend or other restricted payment was made to reimburse Fluence Energy, Inc. for certain tax distributions under the LLC Agreement and certain payments under the Company’s Tax Receivable Agreement and certain operational expenses incurred in connection with the ownership and management of Fluence Energy, LLC. In addition, we were required to maintain (i) minimum liquidity and gross revenue requirements, in each case, until consolidated EBITDA reached $150.0 million for the most recent four fiscal quarters and we made an election, and (ii) thereafter, a maximum total leverage ratio and a minimum interest coverage ratio. Such covenants were tested on a quarterly basis. Asset-Based Lending Facility On November 22, 2023, the Company entered into an asset-based syndicated credit agreement with revolving commitments in an aggregate principal amount of $400.0 million (the "ABL Facility"), by and among Fluence Energy, LLC, as parent borrower, Fluence Energy, Inc., as parent, the other borrowers party thereto, the other guarantors party thereto, the lenders party thereto (the “ABL Lenders”), and Barclays Bank PLC (“Barclays”), as administrative agent (the "ABL Credit Agreement"). The ABL Facility is secured by (i) a first priority pledge of Fluence Energy, Inc.’s equity interests in Fluence Energy, LLC and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, Inc., Fluence Energy, LLC and Fluence Energy Global Production Operation, LLC, in each case, subject to customary exceptions and limitations. Borrowings under the ABL Facility will mature, and lending commitments thereunder will terminate, on November 22, 2027. The Company entered into that certain Master Assignment and Assumption and Issuing Bank Joinder, effective December 15, 2023, with Citibank N.A., the ABL Lenders, and Barclays, adding Citibank N.A. as a lender party to the ABL Facility (the “ABL Joinder”). Borrowing availability under the ABL Facility is determined by a borrowing base calculation that is based on specified percentages of U.S. eligible inventory, net orderly liquidation value of most recent inventory appraisal, and U.S. eligible in-transit inventory, less the aggregate amount of any reserves. The ABL Credit Agreement provides for a full cash dominion period (a) if an event of default is occurring or (b) beginning on the date on which Excess Availability is less than the greater of (i) 12.5% of the Line Cap and (ii) if the borrowing base then in effect is (A) less than $200.0 million, $25.0 million and (B) greater than or equal to $200.0 million, $50.0 million. Line Cap is defined under the ABL Facility as the lesser of the total commitments of the ABL Lenders and the borrowing base. Excess Availability is defined under the ABL Facility as an amount equal to (a) the lesser of (i) the total commitments of all lenders and (ii) the borrowing base, minus (b) total revolving extensions of credit then outstanding at anytime. The ABL Credit Agreement sets forth that (i) loans comprising each ABR Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Alternate Base Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability (as defined in the ABL Credit Agreement) during the applicable determination period, (ii) loans comprising each Canadian Prime Loan Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Canadian Prime Rate (as defined in the ABL Credit Agreement) plus an additional margin ranging from 1.00% to 1.50%, depending on the Average Excess Availability during the applicable determination period, and (iii) the loans comprising each Term Benchmark Borrowing (as defined in the ABL Credit Agreement) shall bear interest at the Adjusted Term SOFR Rate, the Adjusted EURIBOR Rate or Adjusted Term CORRA (each as defined in the ABL Credit Agreement), as applicable, plus an additional margin ranging from 2.00% to 2.50%, depending on the Average Excess Availability during the applicable determination period, in each instance subject to customary benchmark replacement provisions. Fluence Energy, LLC is required to pay to the ABL Lenders a commitment fee on the average daily unused portion of the commitments through maturity, which shall accrue at the rate of (a) until the last day of the first full calendar quarter following the closing of the ABL Facility, 0.450% per annum, and (b) thereafter, 0.450% per annum if average revolving loan utilization is less than or equal to 50% and 0.375% per annum if average revolving loan utilization is greater than 50%. The ABL Facility also provides for a letter of credit sublimit in the amount of $200.0 million, if certain conditions are met. Each letter of credit issuance will be conditioned upon, among other conditions, the payment of certain customary issuance and administration fees, as well as payment of a fronting fee to each issuer thereof and payment of a letter of credit participation fee payable to the ABL Lenders. The ABL Credit Agreement contains customary covenants for this type of financing, including, but not limited to, covenants that restrict our ability to incur indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; pay dividends, make distributions or other restricted payments; and engage in affiliate transactions. The ABL Credit Agreement limits our ability to make certain payments, including dividends and distributions on Fluence Energy, LLC’s equity, the Company’s equity and other restricted payments. Under the terms of the ABL Credit Agreement, Fluence Energy, LLC and its subsidiaries are currently limited in their ability to pay cash dividends to, lend to, or make other investments in Fluence Energy, Inc., subject to certain exceptions. In addition, if certain payment conditions under the ABL Credit Agreement are satisfied, including the satisfaction of a minimum excess availability requirement, then additional specified transactions may be made by the Company and its subsidiaries. The Company agreed that it will not, and its subsidiaries will not, permit Total Liquidity (as defined in the ABL Credit Agreement) at any time to be less than the greater of (i) 20% of the Line Cap then in effect and (ii) $64.0 million, and the Company agreed that it will not, and its subsidiaries will not, permit Excess Availability to be less than the greater of (i) $15.0 million and (ii) 10% of the Line Cap then in effect. Such covenants will be tested on a quarterly basis and upon certain restricted payments, the incurrence of indebtedness, certain dispositions and other specified transactions. As of December 31, 2023, we were in compliance with all such covenants or maintained availability above such covenant triggers. As of December 31, 2023, we had no borrowings under the ABL Facility and $0 of letters of credit outstanding, and availability under the facility of $75.2 million. Borrowings Against Note Receivable - Pledged as Collateral In December 2022, the Company transferred $24.3 million in customer receivables to Standard Chartered Bank (“SCB”) in the Philippines for proceeds of $21.1 million. The receivables all related to our largest customer in that country. The underlying receivables transferred were previously aggregated into a long term note, with interest, and has a maturity date of September 30, 2024. In April 2023, the Company aggregated into an additional long term note and transferred an additional $30.9 million in receivables with the same customer to SCB for proceeds of $27.0 million, upon substantially similar terms as the December 2022 transfer and has a maturity date of December 27, 2024. These transactions are treated as secured borrowings as the Company did not transfer the entire note receivables due from the customer to SCB. The Company continues to receive quarterly interest income from the customer, while SCB is responsible for collecting payments on the principal balances which represent the initial receivable balances from the customer. The Company has no other continuing involvement or exposure related to the underlying receivables. For the three months ended December 31, 2023, the Company recorded net interest income of $0.1 million, which represents the aggregate of $1.2 million in interest income and $1.1 million in interest expense recorded in “Interest income, net.” Refer to “Note 13 - Related-Party Transactions” for details regarding borrowings from related parties.

Income Taxes	3 Months Ended
Income Taxes	Dec. 31, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s provision for income taxes is based on the estimated annual effective tax rate, plus discrete items. Income tax benefit was $1.2 million and $0.6 million for the three months ended December 31, 2023 and 2022, respectively. The effective tax rate for the three months ended December 31, 2023 and 2022 was 4.6% and 1.6%, respectively. For the three months ended December 31, 2023, the Company’s effective tax rate differs from the U.S. statutory tax rate of 21% primarily due to valuation allowances. For the three months ended December 31, 2022, the Company’s effective tax rate differs from the U.S. statutory tax rate of 21% primarily due to flow-through losses attributable to the Founders, valuation allowances, and foreign exchange gains. As of each of December 31, 2023 and September 30, 2023, the Company does not believe it has any significant uncertain tax positions and therefore, has not recorded any unrecognized tax benefits. The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establishes valuation allowances when it is more-likely-than-not that all or a portion of a deferred tax asset may not be realized. As of December 31, 2023 and September 30, 2023, the Company had recorded a full valuation allowance against deferred tax assets on Fluence Energy, Inc. primarily related to its investment in Fluence Energy, LLC, as well as on certain foreign subsidiaries based on the weight of available evidence, including cumulative losses. In the event that the valuation allowance related to tax benefits associated with the Tax Receivable Agreement is released in a future period, a Tax Receivable Agreement liability will be recorded based on the amounts probable and reasonably estimable in accordance with ASC 450.
