Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

The following analysis provides information that management believes is relevant to an assessment and understanding of the consolidated financial condition and results of operations of Fluence and should be read in conjunction with the accompanying unaudited consolidated financial statements and related notes thereto included in this Report and in conjunction with our audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2025, filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 25, 2025 (the “2025 Annual Report”). In addition to historical data, this discussion contains forward-looking statements about our business, results of operations, cash flows, financial condition, and prospects based on current expectations that involve risks, uncertainties, and assumptions. Our actual results could differ materially from such forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those discussed in Part I, Item 1A. “Risk Factors” of the 2025 Annual Report and the section titled “Cautionary Statement Regarding Forward-Looking Information” included elsewhere in this Report. Additionally, our historical results are not necessarily indicative of the results that may be expected for any period in the future.

Fluence Energy, Inc. is a holding company whose sole material assets are the limited liability interests in Fluence Energy, LLC (the “LLC Interests”). 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. 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.

Our fiscal year begins on October 1 and ends on September 30. References to “fiscal year 2025,” and “fiscal year 2026” refer to the twelve months ended September 30, 2025 and ending September 30, 2026, respectively.

Key Factors, Trends, and Uncertainties 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 in Part I, Item 1. “Business” and in Part I, Item 1A. “Risk Factors” within our 2025 Annual Report.

Industry Outlook

The utility-scale battery storage industry continues to experience unprecedented growth fueled in large part by: (i) the global transition toward renewable energy, (ii) heightened focus on grid resilience, (iii) overall declining lithium-ion battery prices in the last decade or so, (iv) increased electricity demand, and (v) supportive regulatory frameworks. BloombergNEF estimated in its 2H 2025 Energy Storage Market Outlook published on October 20, 2025 that the global utility scale market, excluding China, will add approximately 3,201 GWh between 2024 and 2035.

Growth of the battery storage industry and the continued adoption of energy storage solutions by our customers has been driven in part by the overall decrease in cost of lithium-ion energy storage hardware, mainly the cost of lithium-ion batteries, over the last decade or so. However, we have recently seen an increase in prices of lithium carbonate and other commodities since December 2025. The market for energy storage continues to rapidly evolve and while we believe lithium-ion battery costs will continue to decline over the long-term, they may not decline or decline at the rates we expect, if at all over the long-term. Our revenue growth is directly tied to the continued adoption of energy storage products by our customers, which may be affected by commodity raw material price fluctuations and component price fluctuations. As we have not historically been the buyer of raw materials for our components and energy storage products, we have not historically entered into hedging arrangements to mitigate commodity risk. Significant price changes or reduced availability for our raw materials and components has had and may in the future have a deleterious effect on our business, financial condition, and results of operations.

Regulatory and Supply Chain Updates

Our energy storage business is supported by a strategically diversified global supply chain. We continue to work to align our U.S. procurement strategy with the Inflation Reduction Act of 2022 (the “IRA”) and the One Big Beautiful Bill Act (“OBBBA”) as well as related agency guidance relating thereto. We believe that continued expansion and emphasis on domestic content under the IRA, as

modified by the OBBBA, will provide Fluence with a competitive advantage. As of the date of this Report, we believe that under the current language of the OBBBA, which is subject to Treasury guidance issued on February 12, 2026 and any future regulations, our U.S. domestic suppliers are in compliance with the new applicable prohibited foreign entity (“PFE”) restrictions set forth in the OBBBA. Our procurement operations, however, remain subject to a complex and evolving supply chain and regulatory landscape. For more information about the potential risks relating to regulation and compliance and our supply chain, see Part I, Item 1A. “Risk Factors” in our 2025 Annual Report.

Our energy storage solutions incorporate many components and materials sourced from a variety of countries, resulting in exposure to international supply chain risks and logistics disruptions. Uncertain potential actions, policies, and legislation of various government authorities on international and domestic trade, including new or increased tariffs or quotas, border taxes, embargoes, safeguards, duties arising out of various governmental investigations, trade controls, and customs restrictions may impact our ability to manage our costs of production which may then impact our business and results of operations. For example, on February 20, 2026, the U.S. Supreme Court invalidated tariffs imposed by the U.S. government under the International Emergency Economic Powers Act (“IEEPA”). In March 2026, the U.S. Court of International Trade ruled that the U.S. Customs and Border Protection (“CBP”) must refund duties imposed under IEEPA. In response, CBP launched the Consolidated Administration and Processing of Entries portal within the Automated Commercial Environment on April 20, 2026, and the Company has filed a claim for a refund of IEEPA tariffs previously paid. In addition, immediately after issuance of the decision regarding the IEEPA tariffs, the U.S. government initiated new tariffs under alternative authorities. There remains substantial uncertainty regarding the duration of existing and newly announced tariffs and surcharges, potential changes or pauses to such tariffs, the tariff refund process and timing related thereto, tariff levels, and whether further additional tariffs or other retaliatory actions may be imposed, modified, or suspended, and the impacts of such actions on Fluence’s business. Fluence continues to monitor and evaluate these developments and assess their potential impact on our business, financial condition, and results of operations. See Part I, Item 1A. “Risk Factors” in our 2025 Annual Report for further discussion on risks relating to changes in the trade environment.

Legal Proceedings and Legal Contingencies

The results of any current or future litigation, government investigations, or other regulatory or legal proceedings to which we are a party 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, litigation, government investigations, and other regulatory or legal proceedings.

For a description of our material pending legal contingencies, please see “Note 14 - Commitments and Contingencies”, to the unaudited condensed consolidated financial statements included elsewhere in this Report.

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.

We cannot guarantee that our contracted backlog will result in actual revenue in the originally anticipated period or at all. Contracted backlog may not generate margins equal to our historical operating results. 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 fails to result in revenue as anticipated or in a timely manner, we could experience a reduction in revenue, profitability, and liquidity.

Contracted/Order Intake

Contracted, which we use interchangeably with “order intake”, represents new energy storage product and solutions 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 and solutions, 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 pipeline will result in actual revenue in the originally anticipated period or at all. Even if our pipeline generates revenue, it may not generate margins equal to our historical operating results. Among other factors, our pipeline may be impacted by customer project delays or cancelled orders as a result of external market factors and economic or other factors beyond our control. If our pipeline fails to result in revenue or margins as anticipated or in a timely manner, we could experience a reduction in anticipated revenue, profitability, and liquidity.

Key Components of Our Results of Operations

The following discussion describes certain line items in our consolidated statements of operations.

Total Revenue

We generate revenue from battery-based energy storage solutions, service agreements with customers to provide operational services related to battery-based energy storage solutions, 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 battery-based energy storage solutions. Generally, we must design the project, as each energy storage solution is customized depending on a customer’s energy needs, procure the major equipment, obtain manufacturing slots from our contract manufacturers, coordinate the logistics, and assemble the solution prior to delivery and installation at our customer project sites. The Company recognizes revenue over time when we have enforceable right to payment for work performed to date and the solution, in its completed state, does not have an alternative use to the Company.

Our revenue from selling battery-based energy storage solutions is affected by volume fulfilled, which is dependent on customer schedules and demand, changes in price, which is primarily dependent on the cost of lithium-ion energy storage hardware, and mix of products and solutions purchased by 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 include both direct labor costs as well as costs attributable activities related to the transformation of raw materials or component parts into finished goods or the

70

transportation of materials to the customer. Cost of goods and services are recognized when services are performed or when goods are included in our measure of progress as progress relevant costs, which is when they are restricted to a specific customer’s project.

Our product costs are affected by the underlying cost of raw materials, such as lithium-ion, and components to our solutions including inverters. Our product costs are also affected by 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 directly 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 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 are primarily affected by our volume fulfilled, product prices, product costs and project execution.

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.

Research and Development Expenses

Research and development expenses consist primarily 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 and costs of materials and services procured for research and development projects. Engineering competencies include data science, machine learning, software development, network and cybersecurity, 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: 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, a testing facility located in Erlangen, Germany, and a deployment center located in Long Beach, California. We have established 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 as we continue to invest in R&D 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, employee benefits and factoring discounts on receivables sold. 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, developed technology, and capitalized software 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 Expense (Income), net

Interest expense (income), net consists primarily 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

71

against notes receivable pledged as collateral, interest on the 2030 Convertible Senior Notes, unused line fees and commitment fees related to credit facilities, and amortization of debt issuance costs.

Other Income, net

Other income, net primarily consists of expense or income from foreign currency exchange gains and losses on monetary assets and liabilities, factoring income from sale of receivables, and income or expense due to estimated payments to be made to related parties under the Tax Receivable Agreement, dated October 27, 2021, by and among Fluence Energy, Inc., Fluence Energy, LLC, Siemens Industry, Inc. and AES Grid Stability, LLC (the “Tax Receivable Agreement”).

Income Tax Expense

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 that 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.

Net Income (Loss)

Net income (loss) may vary from quarter to quarter and is primarily affected by our gross profit and operating expenses as defined above.

Total Revenue

Total revenue decreased by $435.7 million, or 16.1%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The decrease in total revenue for the fiscal year ended September 30, 2025 was mainly attributable to a $475.7 million decrease in revenue from our energy storage solutions which was primarily driven by lower average price per GWh of our newer Gridstack Pro solutions projects as the cost of lithium-ion batteries has continued to decline, as described above in “Part I, Item 1, Business,” while the total volume of solutions projects fulfilled was relatively consistent year over year. Notwithstanding this consistency, volume was less than expected, primarily due to (i) delays in signing large contracts in Australia that were expected to be signed at the beginning of the year, (ii) delays in fulfilling certain projects in the U.S. due to tariff uncertainties and (iii) delays due to

72

our contract manufacturer scaling newly commissioned U.S. production facility in Arizona. The decrease in revenue from our energy storage solutions was partially offset by a $39.1 million increase of services revenue primarily due to additional energy storage solutions being deployed and transitioned to assets under management and increases in augmentation activities performed for certain projects.

Cost of Goods and Services

Cost of goods and services decreased by $390.4 million, or 16.6%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The decrease in cost of goods and services for the fiscal year ended September 30, 2025 was primarily attributable to (i) a decrease in related cost of lithium-ion batteries while the total volume of solutions project fulfilled remained consistent year over year as described above in “Total Revenue,” and (ii) improved operational efficiencies on our legacy Gridstack solutions projects. The improved operational efficiencies were reflected by the net improvement of gross margins on the portfolio of Gridstack solutions projects in the current period. The cost decrease was slightly offset by a corresponding increase in services costs related to the increases in services revenue described above in “Total Revenue.”

Gross Profit and Gross Profit Margin

Gross profit decreased by $45.3 million, or 13.3%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The decrease in gross profit for the fiscal year ended September 30, 2025, was primarily due to decrease in related cost of lithium-ion batteries in connection with fulfilling consistent volumes of solutions projects year over year as described above in “Revenue” and “Cost of Goods and Services.” However, as described above the total volumes of solutions projects fulfilled were lower than expected. The reduction in costs due to the improved operational efficiencies on legacy Gridstack solutions projects were the primary driver of the improvement in gross profit margin.

Research and Development Expenses

Research and development increased by $20.0 million, or 30.2% in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The increase in research and development expenses for the fiscal year ended September 30, 2025 was primarily attributable to (i) a $16.1 million increase in expenditures for materials and supplies and consulting services related to Smartstack and Gridstack Pro product lines and (ii) a $4.1 million increase in salaries and personnel-related expenses, including stock-based compensation, due to an increase in headcount.

Sales and Marketing Expenses

Sales and marketing expenses increased by $15.6 million, or 24.5%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The increase in sales and marketing expenses for the fiscal year ended September 30, 2025 was primarily attributable to a $12.0 million increase in salaries and personnel-related expenses, including stock-based compensation, due to an increase in headcount to support our growth.

General and Administrative Expenses

General and administrative expenses decreased by $9.9 million, or 5.7%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The decrease in general and administrative expenses for the fiscal year ended September 30, 2025 was primarily attributable to a $23.7 million decrease in salaries and personnel-related expenses, including stock-based compensation, due to less bonus accruals recognized and a decrease in headcount, partially offset by (i) a $7.4 million increase in insurance costs due to higher corporate coverage and (ii) a $5.8 million increase in amortization of the capitalized software development costs associated with hosting arrangements.

Depreciation and Amortization

Depreciation and amortization increased by $1.9 million, or 16.8%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024, primarily attributable to an increase in amortization of capitalized software.

Interest Expense (Income), Net

Interest expense (income), net increased by $9.8 million in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024, primarily attributable to interest expense of $8.6 million recognized for the 2030 Convertible Senior Notes.

Other Income, Net

Other income, net decreased by $1.9 million, or 26.1%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The decrease in other income, net was primarily attributable to a $2.7 million net decrease in favorable foreign currency exchange gains on monetary assets and liabilities compared to the prior period.

73

Income Tax Expense

Income tax expense increased by $13.7 million, or 148.9%, in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The increase in tax expense is primarily due to increased profitability at the Company’s foreign subsidiaries in the United Kingdom, Germany and Australia.

Net (Loss) Income

Net loss increased by $98.4 million in the fiscal year ended September 30, 2025, as compared to the fiscal year ended September 30, 2024. The increase is primarily attributable to (i) a decrease in “Gross profit,” (ii) an increase in “Research and development expenses,” and (iii) an increase in “Sales and marketing expenses,” each as described above.

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 expense (income), net, (ii) income taxes, (iii) depreciation and amortization, (iv) stock-based compensation, and (v) other non-recurring income or expenses. Adjusted EBITDA also includes amounts impacting net income related to estimated payments due to related parties pursuant to the Tax Receivable Agreement.

Adjusted Gross Profit is calculated using gross profit, adjusted to exclude (i) stock-based compensation expenses, (ii) depreciation and amortization, and (iii) other 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.

These non-GAAP measures are intended as supplemental measures of performance and/or liquidity that are neither required by, nor presented in accordance with, U.S. generally accepted accounting principles (“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 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. With respect to Free Cash Flow, limitations on its use include that (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.

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

Liquidity and Capital Resources

Since inception and through September 30, 2025, our principal sources of liquidity have been the proceeds from our IPO, our cash and cash equivalents from operations, short-term borrowings, borrowings available under our debt agreements, proceeds from the issuance of the 2030 Convertible Senior Notes (as defined below), supply chain financing, capital contributions from AES Grid Stability, LLC (“AES Grid Stability”) and Siemens Industry, LLC (“Siemens Industry”) and proceeds from the investment by QIA Florence Holdings, LLC, an affiliate of Qatar Holding LLC in 2021, proceeds from short term investments, borrowings against note receivables, and proceeds from sale of accounts receivable under the MRPA (as defined below).

We believe our existing cash and cash equivalents, which includes proceeds from our IPO, cash flows from operations, and proceeds from the issuance of the 2030 Convertible Senior Notes, in addition to our supply chain financing arrangements, and availability under our 2024 Revolver (as defined below) will be sufficient to meet our expense and capital requirements for at least the next 12 months following the filing of this Annual Report.

Our capital requirements, and ability to generate cash flow, have been and may in the future vary materially from those planned and will depend on many factors, including our rate of revenue growth, the timing and extent of our growth initiatives, our introduction of new products, services, and digital application offerings and related costs and expenses, and overall regulatory and macroeconomic conditions, including, among others, factors relating to inflation, interest rate environment, impacts of tariffs and trade restrictions, labor shortages, supply chain disruptions, changing consumer behavior, increased competition, and pandemics like COVID-19. 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.

2030 Convertible Senior Notes

In December 2024, the Company issued $400.0 million aggregate principal amount of 2.25% convertible senior notes due 2030. The 2030 Convertible Senior Notes were issued pursuant to, and are governed by, an indenture, dated as of December 12, 2024,

75

between the Company and UMB Bank, National Association, as trustee (the “Indenture”). The net proceeds from the issuance of the 2030 Convertible Senior Notes were $389.4 million, net of $10.6 million of debt issuance costs.

In connection with the 2030 Convertible Senior Notes, the Company entered into privately negotiated capped call transactions with certain financial institutions pursuant to capped call confirmations (collectively the “Capped Calls”). The premiums paid for the purchases of the Capped Calls were $29.0 million. The Capped Calls have an initial strike price of approximately $21.35 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2030 Convertible Senior Notes. The Capped Calls have an initial cap price of $28.74 per share, subject to certain adjustments substantially similar to those applicable to the corresponding 2030 Convertible Senior Notes.

For further discussion of the 2030 Convertible Senior Notes and the Capped Calls, refer to “Note 13 - Convertible Senior Notes, Net” to our condensed consolidated financial statements included elsewhere in this Annual Report.

Supply Chain Financing

We provide certain of our suppliers with access to two different supply chain financing programs through two different third-party financing institutions (each a “SCF Bank”). These supply chain financing (“SCF”) programs 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 either program and reaches an agreement with the respective SCF Bank, the supplier elects which individual invoices to sell to the respective SCF Bank. We then pay the respective SCF Bank on the applicable due date. We have no economic interest in a supplier’s decision to sell a receivable to the SCF Banks. The agreements between our suppliers and the SCF Banks are solely at their discretion and are negotiated directly between them. Under our original supply chain financing arrangement (the “Original SCF Facility”), our suppliers’ ability to continue using such agreements is primarily dependent upon the strength of our financial condition and guarantees issued by The AES Corporation and Siemens Corporation, a subsidiary of Siemens AG, pursuant to the terms of the Credit Support and Reimbursement Agreement (as defined below). As of September 30, 2025, The AES Corporation and Siemens Corporation issued guarantees of $50.0 million each, for a total of $100.0 million, to the original SCF Bank on our behalf.

The Company entered into a new $150.0 million supply chain financing arrangement (the “New SCF Facility”) with a third-party financial institution (the “New SCF Bank”) on August 8, 2025. This New SCF Facility allows the Company 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. Such sales are at the sole discretion of the supplier, and on terms and conditions that are negotiated between the supplier and the New SCF Bank. The Company is not a party to the arrangement between its suppliers and the New SCF Bank and the Company has no economic interest in a supplier’s decision to sell an underlying receivable to the New SCF Bank. The Company does not provide secured legal assets or other forms of guarantees under this arrangement, nor do any of the Company’s affiliates. Under the New SCF Facility, we are required to maintain a liquidity ratio of 2:1 as of the last day of each calendar month. Liquidity ratio is defined as the ratio of (i) liquidity to (ii) the sum of (x) the aggregate outstanding notional amount of all receivables, bills of exchange or similar negotiable instruments purchased by the original SCF Bank under the existing supply chain financing arrangement described above and (y) the aggregate outstanding notional amount of payables outstanding under this New SCF Facility. Liquidity under the New SCF Facility includes the Company’s cash and cash equivalents and aggregate availability under the Company’s committed credit facilities, including the 2024 Revolver. As of September 30, 2025, no suppliers participated in the New SCF Facility, and the Company had no outstanding payment obligations to the New SCF Bank.

Shelf Registration Statement

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, subject to our continued eligibility to use such form. 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.

76

Revolving Credit Facility

On November 1, 2021, we entered into a credit agreement for a revolving credit facility (the “Revolver”), by and among Fluence Energy, LLC, as 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 (as amended, the “Revolving Credit Agreement”). The aggregate amount of commitments was $200.0 million. The Revolving Credit Agreement was terminated effective November 22, 2023, in conjunction with the entry into the ABL Credit Agreement (as further described below), and at such time, the Company prepaid all amounts outstanding under the Revolver and terminated all commitments thereunder. No penalties were required to be paid as a result of the termination.

For further discussion of the Revolver, refer to “Note 12 - Debt” to our condensed consolidated financial statements included elsewhere in this Annual Report.

Asset-Based Lending Facility

On November 22, 2023, the Company entered into an asset-based syndicated credit agreement (the “ABL Credit Agreement”) 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, as administrative agent, which was amended by the Master Assignment and Assumption and Issuing Bank Joinder, effective December 15, 2023 (the “ABL Joinder”), Amendment No. 1, dated April 8, 2024 (“Amendment No. 1”), and Amendment No. 2, dated May 8, 2024 (“Amendment No. 2”), which provided for revolving commitments in an aggregate principal amount of $400.0 million (the "ABL Facility"). The ABL Facility was 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 were scheduled to mature, and lending commitments thereunder would terminate, on November 22, 2027, which remains the maturity date of borrowings under the 2024 Revolver. As of the time of our entry into Amendment No. 3 to the ABL Credit Agreement (as discussed below), there were no outstanding borrowings under the ABL Facility or letters of credit outstanding.

For further discussion of the ABL Credit Agreement, refer to “Note 12 - Debt” to our consolidated financial statements included elsewhere in this Annual Report.

2024 Revolver

On August 6, 2024 (the "Amendment Effective Date"), Fluence Energy, Inc. entered into Amendment Number Three ("Amendment No. 3") to that certain ABL Credit Agreement by and among Fluence Energy, LLC, as parent borrower, the Company, as parent, the other borrowers party thereto, the other guarantors party thereto, the lenders party thereto, and Citibank, N.A., as administrative agent (as successor to Barclays Bank PLC) (such agreement, as so amended, the "2024 Credit Agreement") in order to (i) convert the existing ABL Facility to a senior secured cash flow revolving credit facility in an initial aggregate principal amount of up to $500.0 million (the "2024 Revolver"), (ii) replace Barclays Bank PLC as administrative agent under the 2024 Credit Agreement with Citibank, N.A., and (iii) make certain other modifications to the 2024 Credit Agreement as set forth therein. Capitalized terms used in this subsection that are not otherwise defined are defined in the 2024 Credit Agreement.

The 2024 Revolver is secured by (i) a first priority pledge of the Company's equity interests in Fluence Energy, LLC and Fluence Energy Global Production Operation, LLC, (ii) first priority security interests in substantially all tangible and intangible personal property of the Company, Fluence Energy, LLC, Fluence Energy Global Production Operation, LLC and certain of its foreign subsidiaries, in each case, subject to customary exceptions and limitations, and (iii) a pledge of the Company's equity interests in certain of its foreign subsidiaries and security interests in certain assets of such foreign subsidiaries.

The 2024 Credit Agreement sets forth that (i) loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus 2.00%, (ii) loans comprising each Term Benchmark Borrowing shall bear interest at the Term SOFR Rate or the Adjusted EURIBOR Rate, as applicable, plus 3.00%, and (iii) the loans comprising each RFR Borrowing shall bear interest at the Daily Simple RFR plus 3.00%, 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 lenders a commitment fee on the average daily unused portion of the commitments through maturity, which shall accrue at the rate of 0.50% per annum. The 2024 Credit Agreement provides for a cash draw sublimit of $150.0 million as well as a letter of credit sublimit in the amount of $500.0 million if certain conditions are met.

The 2024 Credit Agreement contains customary covenants for this type of financing, including, but not limited to, covenants that restrict our and certain of our subsidiaries’ 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 2024 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 2024 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 the

77

Company, subject to certain exceptions. In addition, we are required to maintain (i) from the Amendment Effective Date through December 31, 2025, Total Liquidity of no less than $150,000,000, (ii) from January 1, 2026 and thereafter, Total Liquidity of no less than $100,000,000 or a Consolidated Leverage Ratio as of the last day of any Measurement Period not to exceed 3.50:1.00, and (iii) certain other financial requirements at each Guarantor Coverage Test Date. Such covenants are tested on a quarterly basis and upon the occurrence of other certain restricted payments, the incurrence of indebtedness, certain dispositions, and other specified transactions. As of September 30, 2025, we were in compliance with all such covenants.

The 2024 Credit Agreement contains customary events of default for this type of financing. If an event of default occurs with respect to a borrower, the lenders will be able to, among other things, terminate the commitments immediately, cash collateralize any outstanding letters of credit, declare any loans outstanding to be due and payable in whole or in part, and exercise other rights and remedies. The maturity date and the date of termination of lending commitments under the 2024 Credit Agreement is November 22, 2027. As of September 30, 2025, there are no cash borrowings under the 2024 Revolver, and there are $194.4 million letters of credit outstanding under the 2024 Revolver, with remaining availability of $305.6 million, net of letters of credit issued.

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 a maturity date of September 30, 2024. In April 2023, we 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 with a maturity date of December 27, 2024. These transactions were treated as secured borrowings as we did not transfer the entire note receivables due from the customer to SCB. We continued to receive quarterly interest income from the customer, while SCB was responsible for collecting payments on the principal balances which represented the initial receivable balances from the customer. We had no other continuing involvement or exposure related to the underlying receivables. On September 16, 2024 and December 27, 2024, $24.3 million and $30.9 million of receivables, respectively, were paid in full, resulting in the release of the corresponding notes and borrowings.

Sale of Receivables under Master Receivables Purchase Agreement

On February 27, 2024, Fluence Energy, LLC entered into a Master Receivables Purchase Agreement (the “MRPA”), by and among Fluence Energy, LLC and any other seller from time to time party thereto, as sellers and servicers, and Credit Agricole Corporate and Investment Bank ("CACIB"), as purchaser. Pursuant to the MRPA, Fluence Energy, LLC may sell certain receivables (the “Purchased Receivables”) to CACIB from time to time, and CACIB may agree to purchase the Purchased Receivables in each case, on an uncommitted basis. The MRPA provides that the outstanding amount of all purchased receivables under the MRPA will not exceed $75.0 million, with sublimits for each account debtor and for certain kinds of receivables. The MRPA may be terminated by either party at any time by 30 days’ prior written notice. Fluence Energy, LLC has granted CACIB a security interest in the purchased receivables, and proceeds thereof, as more fully described in the MRPA, in order to perfect CACIB’s ownership interest in the purchased receivables and secure the payment and performance of all obligations of Fluence Energy, LLC to CACIB under the MRPA. The MRPA contains other customary representations and warranties and covenants.

When receivables are sold under the MRPA, they are sold without recourse, and our continuing involvement is limited to their servicing, for which the Company receives a fee commensurate with the service provided and therefore no servicing asset or liability related to these receivables was recognized for any period presented. The fair value of the sold receivables approximated their book value due to their short-term nature.

Credit Support and Reimbursement Agreement

We are party to an Amended and Restated Credit Support and Reimbursement Agreement, dated June 9, 2021, with The AES Corporation (“AES”) and Siemens Industry (the “Credit Support and Reimbursement Agreement”) 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, reimbursement of actual costs and expenses incurred in having a credit support instrument issued and maintained, and reimbursement for all amounts paid to our lenders or other counterparties, payable upon demand. The Amended and Restated Credit Support and Reimbursement Agreement had an initial expiration date of June 9, 2025 (the “initial expiration date”), but will automatically and indefinitely continue thereafter pursuant to its terms until either AES or Siemens Industry terminates the agreement upon six months’ prior notice. No notice of termination has been provided by the time of filing of this Annual Report. 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.

78

Currently, the Company has outstanding performance guarantees provided by AES and Siemens Industry and their respective affiliates that guarantee Fluence’s performance obligations under certain contracts with Fluence’s customers. These performance guarantees are issued pursuant to the terms of the Credit Support and Reimbursement Agreement. Fluence paid performance guarantee fees to its affiliates in exchange for guaranteeing Fluence’s performance obligations under certain contracts with Fluence’s customers. The guarantee fees are included in “Cost of goods and services” on Fluence’s condensed consolidated statements of operations. Guarantees are also issued by AES and Siemens Corporation, pursuant to the terms of the Credit Support and Reimbursement Agreement, in connection with one of our supplier chain financing programs (as described in greater detail above).

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. 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 the Third Amended and Restated Limited Liability Agreement of Fluence Energy, LLC, dated October 27, 2021, as may be amended from time to time (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 our Class B-1 common stock, par value $0.00001 per share (“Class B-1 common stock”). On December 8, 2023, AES Grid Stability exercised its redemption right pursuant to the terms of the 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 our Class B-1 common stock.

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 Internal Revenue Service 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 $137.6 million. The Founders will be entitled to receive payments under the Tax Receivable Agreement equaling 85% of such amount, or $117 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.

With the exception of an estimated $0.3 million of Tax Receivable Agreement payment realized as of September 30, 2025, 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 remaining liability. Should we determine that the additional 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.

Commitments, Contingencies, and Off-Balance Sheet Arrangements

As of September 30, 2025, 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. In addition, we have a limited number of parent company guarantees and letters of credit issued as payment security to certain vendors. The Company also has certain battery purchase

79

obligations and spending requirements under our master supply agreement with suppliers. We are also party to both assurance and service-type warranties for various lengths of time. Refer to “Note 15 - Commitments and Contingencies” to our condensed consolidated financial statements included elsewhere in this Annual Report for more information regarding our contingent obligations, including off-balance sheet arrangements, and legal contingencies.

Net cash flows used in operating activities was $145.5 million for the fiscal year ended September 30, 2025, compared to net cash provided by operating activities of $79.7 million for the fiscal year ended September 30, 2024. The $225.2 million increase in net cash used in operating activities compared to last year was primarily due to a decrease in working capital balances of $134.6 million and an increase of $98.4 million in net loss. Below we describe in more detail the cash flows (used in) provided by operating activities for each period:

•Net cash flows used in operating activities of $145.5 million for the fiscal year ended September 30, 2025, was primarily due to (i) net loss of $68.0 million, (ii) increases in inventory balances of $278.7 million due to cash expenditures on inventory, and (iii) decreases in accounts payable of $119.2 million and current accruals and provisions of $93.6 million due to the timing of purchases and payments to various vendors. These cash outflows were partially offset by net effects of changes in customer contract assets and liabilities. Specifically, deferred revenue, inclusive of related parties, increased in aggregate by $403.6 million, due to timing of various customer project billings and cash collections in accordance with contract milestone payment schedules.

•Net cash flows provided by operating activities of $79.7 million for the fiscal year ended September 30, 2024, were primarily due to (i) net income of $30.4 million and (ii) increases in accounts payable of $370.1 million and current accruals and provisions of $160.2 million due to the timing of purchases and payments to various vendors. These cash inflows were partially offset by net effects of changes in customer contract assets and liabilities. Specifically, receivables, inclusive of trade, unbilled accounts receivable and receivables from related parties, increasing in aggregate by $393.8 million and (ii) deferred revenue, inclusive of related parties, decreasing in aggregate by $82.0 million, due to timing of various customer project billings and cash collections in accordance with contract milestone payment schedules.

Net cash flows used in investing activities were $29.8 million for the fiscal year ended September 30, 2025 which were primarily due to capital expenditures on software of $14.9 million and purchases of property and equipment of $14.9 million.

Net cash flows used in investing activities were $19.0 million for the fiscal year ended September 30, 2024 which were primarily due to capital expenditures on software of $10.9 million and purchases of property and equipment of $8.1 million.

Net cash flows provided by financing activities were $356.9 million for the fiscal year ended September 30, 2025, which were primarily related to the proceeds received from the issuance of the 2030 Convertible Senior Notes of $400.0 million, partially offset by (i) premiums paid for the purchases of the Capped Calls of $29.0 million and (ii) payments for the debt issuance costs of $12.1 million primarily related to the 2030 Convertible Senior Notes.

Net cash flows used in financing activities were $8.7 million for the fiscal year ended September 30, 2024, which were primarily driven by (i) $8.5 million in payments related to debt issuance costs for the ABL Facility and 2024 Revolver, (ii) $3.9 million in payments for a previously acquired company (Nispera), and (iii) $1.7 million related to Class A common stock withheld related to settlement of employee taxes for stock-based compensation awards, partially offset by $5.3 million of proceeds from the exercise of stock options during the period.

Critical Accounting Policies and Use of Estimates

Our financial statements have been prepared in accordance with 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. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Revenue Recognition - Sale of 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. Our projects have a lead time from date of contract execution to substantial completion, typically ranging from approximately twelve up to eighteen months. Generally, we must design the project, as each storage solution is customized depending on the customer’s energy needs, procure the major equipment, obtain manufacturing slots from our contract manufacturers, coordinate the logistics, and assemble the solution prior to delivery and installation at our customer project sites. These actions must be completed timely to adhere to customer schedules and milestones. Depending on the scope of the project we may be responsible for the installation of the equipment. After the equipment is installed, we are responsible for commissioning. The Company recognizes revenue over time when we have enforceable right to payment for work performed to date and the solution, in its completed state, does not have an alternative use to the Company. Revenue is recognized using the percentage of completion (“POC”) method based on actual cost incurred as a percentage of total estimated contract costs. Standard inventory materials (including batteries, enclosures, chillers, and others, which are assembled into “integrated systems”) are included in our measure of progress when they are restricted to a specific customer’s project such that we no longer have the ability to direct their use for other purposes. Contract costs include all direct material and labor costs related to contract performance. As the cost of the assembled integrated systems comprise a substantial portion of the total estimated contract costs, our pattern of revenue recognition may vary materially from period to period. Our judgment on when costs should be included in the measure of progress may have a material impact on revenue recognition.

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. The Company determines the transaction price based on the consideration expected to be received which includes estimates of variable consideration that are included in the transaction price in accordance with ASC 606. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. For our 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 transaction price 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. Generally, our revenues recognized are not sensitive to the Company’s determination of standalone selling prices. We assess any variable consideration using an expected value method which computes a weighted average amount based on a range of potential outcomes. 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 or if we will not meet certain performance specifications per the contract.

Our contracts generally provide our customers the right to liquidated damages (“LDs”) 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 LD amount when recognizing revenue. The existence and measurement of LDs may also be impacted by our judgments 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 method.

Fluence may incur additional costs to execute on the performance of a contract. When this happens, we typically attempt to recover 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 proportionate revenue, since costs are recognized immediately when incurred and the revenue is recognized based upon the transaction price, which is usually increased upon signing a respective change order with the customer.

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.

Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities.

81

Customer payments are due upon meeting certain milestones as defined in the contract, which are generally consistent with contract-specific phases of a project.

Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Generally, pre-contract costs are not material.
