Summary of Significant Accounting Policies and Estimates | Summary of Significant Accounting Policies and Estimates Principles of Accounting and Consolidation The accompanying condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and under the rules of the U.S. Securities and Exchange Commission (the “SEC”). The accompanying condensed consolidated financial statements include the accounts of Fluence Energy, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Non-Controlling Interest As the sole managing member of Fluence Energy, LLC, Fluence Energy, Inc. operates and controls all the business and affairs of Fluence Energy, LLC and, through Fluence Energy, LLC and its direct and indirect subsidiaries, conducts the Co mpany’s business. Fluence Energy, LLC is a variable interest entity, of which Fluence Energy, Inc. beneficially owns a 71.45% inte rest as of June 30, 2024. For accounting purposes, Fluence Energy, Inc. is considered the primary beneficiary and therefore consolidates the results of Fluence Energy, LLC and its direct and indirect subsidiaries. The table below summarizes the ownership structure at the end of each respective period: June 30, 2024 September 30, 2023 Controlling Interest Ownership 71.45 % 66.99 % Non-Controlling Interest Ownership (AES) 28.55 % 33.01 % Unaudited Interim Financial Information The accompanying condensed consolidated financial statements as of June 30, 2024, and for the three and nine months ended June 30, 2024 and 2023 are unaudited. These financial statements should be read in conjunction with the Company’s audited financial statements included in our Annual Report on Form 10-K for the year ended September 30, 2023 filed with the SEC on November 29, 2023 (the “2023 Annual Report”). In our opinion, such unaudited financial statements reflect all adjustments, including normal recurring items, that are necessary for the fair statement of the Company’s financial position as of June 30, 2024, the results of its operations for the three and nine months ended June 30, 2024 and 2023, and its cash flows for the nine months ended June 30, 2024 and 2023. The financial data and other information disclosed in these notes related to the three and nine months ended June 30, 2024 and 2023 are also unaudited. The results for the three and nine months ended June 30, 2024 and 2023 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; transaction price estimates with variable consideration; accrued bonuses; and various project-related provisions including, but not limited to, estimated losses, warranty obligations. 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. in thousands June 30, 2024 September 30, 2023 Cash and cash equivalents $ 388,242 $ 345,896 Restricted cash 101,988 106,835 Restricted cash included in “Other non-current assets” 23,078 10,000 Total cash, cash equivalents and restricted cash $ 513,308 $ 462,731 Restricted cash at the end of each respective period consisted of the following: in thousands June 30, 2024 September 30, 2023 Collateral for credit card program $ 2,795 $ 2,644 Collateral for outstanding bank guarantees 88,087 102,586 Collateral for surety program 9,428 — Term deposits 1,678 1,605 Collateral for surety program included in “Other non-current assets” 23,078 10,000 Total restricted cash $ 125,066 $ 116,835 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 June 30, 2024, 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 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. 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 a customer’s project. Due to the significance of the costs associated with cubes, our judgment 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 future 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. 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. 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 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 of the consideration to be received. As of June 30, 2024 and September 30, 2023, transaction prices have been reduced to reflect estimates of variable consideration primarily related to liquidated damages of $75.5 million and $84.1 million, respectively. 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 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. For the three months and nine months ended June 30, 2024, we recognized approximately $8.9 million and $16.3 million, respectively, in revenue from changes in transaction prices during the period, in which the performance obligations were substantially satisfied in previous quarterly periods. Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities. 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 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 extended warranty, maintenance, monitoring, and other services. The Company accounts for the services as separate performance obligations from the battery-based energy storage products and solutions. The extended warranty services are typically considered a separate performance obligation from the maintenance, monitoring and other services. We typically recognize revenue ratably over the terms of the services using a straight-line recognition method. The Company believes using a time-based method to measure progress is appropriate as the performance obligations are satisfied evenly over the terms of services. Revenue is recognized for each of the performance obligations by dividing the allocated transaction price over the service period. Some of these agreements also provide a commitment to perform certain augmentation activities which could require us to install 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 other contracts provide a fixed number of augmentations over a contract term. Augmentation arrangements that require us to maintain battery capacity above established thresholds for a given term may be considered service-type warranties depending on the respective contract terms. These represent a stand-ready obligation in which the customer benefits evenly overtime, for 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”) offerings through several market facing applications. These applications currently include Fluence Mosaic and Fluence Nispera. Fluence Mosaic is an intelligent bidding software for utility-scale storage and renewable assets, helping to enable 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 an asset performance management software that helps customers monitor, analyze, forecast, and optimize the performance of their renewable energy assets. Fluence Nispera 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 Digital software applications is separately identifiable from other promises that the Company offers to its customers. As such, Fluence Digital applications are accounted for as separate performance obligations when combined with other Fluence products, solutions, 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 a 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 primarily consists of cubes, batteries and related 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 Cost s 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 nine months ended June 30, 2024 and June 30, 2023, the Company capitalized $7.0 million and $5.5 million, respectively, of internal-use software. 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 non-current assets” on the consolidated balance sheets and are amortized to “General and administrative” once ready for intended use over the estimated useful life of the hosted software. The useful life of our internal-use software development costs associated with hosting arrangements is generally the period the Company expects to benefit from its right to access the hosted software plus consideration for any renewal or cancellation periods. During the nine months ended June 30, 2024 and June 30, 2023, the Company capitalized $24.6 million and $0.0 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 nine months ended June 30, 2024 and June 30, 2023, the Company capitalized $1.6 million and $1.8 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 cash on hand and highly liquid investments readily convertible to cash, with an original maturity of 90 days or less when purchased. Fair value of cash equivalents approximates the carrying amount. The carrying amounts of trade receivables, accounts payable and short-term debt obligations such as current portion of borrowings against note receivable - pledged as collateral, approximate fair values due to their short maturities. The fair value of the Company’s foreign currency derivatives is measured on a recurring basis by comparing the contracted forward exchange rate to the current market exchange rate. The foreign currency derivatives are categorized as Level 2 in the fair value hierarchy, as the inputs to the derivative pricing model are generally observable and do not contain a high level of subjectivity. Refer to “Note 18 – Derivatives and Hedging” for details regarding the Company’s derivatives and hedging activities. Derivatives and Hedging The Company records all derivatives at their gross fair values on the condensed consolidated balance sheets. The accounting for the gains or losses resulting from changes in the fair value of derivatives depends on the intended use of the derivatives, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. The gains or losses from designated cash flow hedges are deferred in accumulated other comprehensive income and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The gains or losses will be presented in the same income statement line item as the earnings effect of the hedged item. The effectiveness of cash flow hedges is assessed at inception and quarterly thereafter. The change in fair value of the components excluded from the assessment of effectiveness are recognized in current period earnings. The changes in fair value of derivatives that are not designated for hedge accounting are recognized in current period earnings. Income (Loss) per Share As of June 30, 2024, the Company’s Amended and Restated Certificate of Incorporation authorizes three classes of common stock: Class A, Class B-1, and Class B-2. Income (loss) per share is calculated and reported under the “two-class” method. The “two-class” method is an earnings allocation method under which income (loss) per share is calculated for each class of common stock considering both distributions declared or accumulated and participation rights in undistributed income (losses) as if all such income (loss) had been distributed during the period. Basic income (loss) per share of Class A common stock is computed by dividing net income (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 income (loss) per share of Class A common stock is computed by adjusting the net income (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 income (loss) per share. In periods in which we have a loss, 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 income (loss) per share: Three Months Ended June 30, Nine Months Ended June 30, 2024 2023 2024 2023 Class B-1 common stock — 58,586,695 51,499,195 58,586,695 Outstanding pre-IPO options issued pursuant to the 2020 Unit Option Plan 445,959 5,911,672 3,492,867 5,911,672 Outstanding pre-IPO phantom units — 256,935 — 256,935 Outstanding restricted stock units (“RSUs”) 1,076,589 1,963,673 1,887,787 1,963,673 Outstanding performance share units (“PSUs”) 356,973 — 386,373 — Outstanding non-qualified stock options (“NQSOs”) 165,521 — 165,521 — Outstanding restricted stock (“Nispera equity”) 37,221 354,134 177,067 354,134 Basic and diluted net income (loss) per share of Class A common stock for the three and nine months ended June 30, 2024 and 2023, respectively, have been computed as follows: Three Months Ended June 30, Nine Months Ended June 30, In thousands, except share and per share amounts 2024 2023 2024 2023 Net income (loss) $ 1,075 $ (35,045) $ (37,357) $ (109,636) Less: Net income (loss) attributable to the non-controlling interest 290 (11,655) (12,230) (36,748) Net income (loss) attributable to Fluence Energy, Inc. $ 785 $ (23,390) $ (25,127) $ (72,888) Weighted average number of Class A common stock: Basic 127,910,081 117,456,282 125,273,648 116,368,987 Diluted 184,219,065 117,456,282 125,273,648 116,368,987 Net income (loss) per share of Class A common stock: Basic $ 0.01 $ (0.20) $ (0.20) $ (0.63) Diluted $ — $ (0.20) $ (0.20) $ (0.63) Recent Accounting Standards Adopted The following table presents accounting standards adopted during the nine months ended June 30, 2024. Standard Description Period of Adoption Effect on the financial statements and other significant matters Accounting Standards Update (“ASU”) No. 2022-04: Liabilities-Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations ASU 2022-04 requires entities to disclose the key terms of supplier finance programs they use in connection with the purchase of goods and services, along with the amount of obligations outstanding at the end of each period and an annual roll forward of such obligations. This standard does not affect the recognition, measurement, or financial statement presentation of supplier finance program obligations. As of the three months ended December 31, 2023. The Company presented the key terms of its supply chain financing programs along with a roll forward of activity in “Footnote 16 - Supply Chain Financing.” There was no impact as a result of the adoption on financial statement presentation or results of operations for any period presented. Recent Accounting Standards Not Yet Adopted The following table presents accounting standards not yet adopted: Standard Description Required date of adoption Effect on the financial statements and other significant matters ASU No. 2023-07: Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. The update requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances.
