Fluence Energy Inc

There have been no material changes with respect to our risk factors previously disclosed in our 2024 Annual Report, other than as set forth below. You should carefully consider the risks described in Item 1A. "Risk Factors" of our 2024 Annual Report, and all of the other information included in this Report, before making an investment decision. Our business, financial condition, and results of operations could be materially and adversely affected by any of these risks or uncertainties.

Risks Related to the 2030 Convertible Senior Notes

Our indebtedness and liabilities could limit the cash flow available for our operations, expose us to risks that could adversely affect our business, financial condition, and results of operations and impair our ability to satisfy our obligations under the 2030 Convertible Senior Notes.

As of December 31, 2024, we had approximately $400.0 million of indebtedness outstanding under the 2030 Convertible Senior Notes, and no cash borrowings outstanding under the 2024 Revolver (excluding$99.3 million letters of credit outstanding thereunder), with remaining availability of $400.7 million, net of letters of credit issued. All borrowings and obligations under the 2024 Revolver will be effectively senior to our obligations under the 2030 Convertible Senior Notes to the extent of the value of the assets securing such borrowings and obligations, and structurally senior to the 2030 Convertible Senior Notes as the 2030 Convertible Senior Notes are not guaranteed by Fluence Energy, LLC, a borrower under the 2024 Revolver.

We may also incur additional indebtedness to meet future financing needs. Our indebtedness could have significant negative consequences for our security holders and our business, results of operations, and financial condition by, among other things:

•making it more difficult for us to satisfy our obligations with respect to our 2030 Convertible Senior Notes and our other debt;

•increasing our cost of borrowing.

Any additional indebtedness we incur will heighten the potential for the consequences discussed above and could negatively impact our credit ratings, if any, in the future.

Our business may not generate sufficient funds, and we may otherwise be unable to maintain sufficient cash reserves, to pay amounts due under our indebtedness, including the 2030 Convertible Senior Notes, and our cash needs may increase in the future. In addition, the 2024 Revolver contains and any future indebtedness that we may incur may contain, financial and other restrictive covenants that limit our ability to operate our business, raise capital, or make payments under our other indebtedness. If we fail to comply with these covenants or to make payments under our indebtedness when due, then we would be in default under that indebtedness, which could, in turn, result in that and our other indebtedness becoming immediately payable in full.

We conduct all of our operations through our subsidiaries, including Fluence Energy, LLC, and may not be able to receive dividends or other distributions in needed amounts from our subsidiaries; Fluence Energy, Inc. is a holding company.

We conduct all of our operations through our subsidiaries, including Fluence Energy, LLC; Fluence Energy, Inc. is a holding company. Accordingly, payment of interest or repayment of principal on our indebtedness, including the

2030 Convertible Senior Notes, is significantly dependent on the generation of cash flow by our subsidiaries and their ability to make such cash available to us, by dividend, interest payment on debt they owe to us (including interest payments on the 2.25% Intercompany Subordinated Convertible Note issued by Fluence Energy, LLC to Fluence Energy, Inc., dated December 12, 2024 (the “Intercompany Convertible Note”)), debt repayment, or otherwise. None of our subsidiaries will guarantee the 2030 Convertible Senior Notes and our subsidiaries will not have any obligation to pay amounts due on the 2030 Convertible Senior Notes or to make funds available for that purpose. Noteholders are not entitled to rights under the Intercompany Convertible Note. Fluence Energy, LLC’s failure to make interest payments thereunder will not itself constitute a default or event of default under the indenture governing the 2030 Convertible Senior Notes. We have pledged our interest in the Intercompany Convertible Note to secure our obligations under the 2024 Revolver, and the Intercompany Convertible Note is subordinated in right of payment to Fluence Energy, LLC’s obligations under the 2024 Revolver and its other indebtedness. Our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to make payments in respect of our indebtedness, including the 2030 Convertible Senior Notes. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. While the agreement governing our 2024 Revolver limits the ability of certain of our subsidiaries to incur consensual restrictions on their ability to pay dividends or make other intercompany payments to us, these limitations are subject to qualifications and exceptions. Additionally, the agreement governing our 2024 Revolver limits the ability of Fluence Energy, LLC to pay dividends or make other distributions to us, and substantially limits our ability to prepay or repay the principal amount of the 2030 Convertible Senior Notes with cash, upon conversion, maturity or otherwise. Furthermore, other holders of LLC Interests are entitled to participate pro rata with Fluence Energy, Inc. in dividends from Fluence Energy, LLC. In the event that we do not receive distributions from our subsidiaries, we may be unable to make required principal and interest payments on our indebtedness, including the 2030 Convertible Senior Notes.

Higher interest rates could increase the cost of refinancing our indebtedness and could cause our debt service obligations to increase significantly.

The current high interest rate environment could adversely impact us. If interest rates remain at their current elevated levels or continue to increase, this could adversely impact our ability to refinance existing indebtedness or obtain additional debt financing on acceptable terms or at all. In addition, we expect this refinancing effort will, and future debt refinancings may, increase our debt service obligations as we refinance lower interest rate debt with higher interest rate debt.

The conditional conversion feature of the 2030 Convertible Senior Notes, if triggered, may adversely affect our financial condition and results of operations.

In the event the conditional conversion feature of the 2030 Convertible Senior Notes is triggered, noteholders will be entitled to convert the 2030 Convertible Senior Notes at any time during specified periods at their option. If one or more holders elect to convert their 2030 Convertible Senior Notes, we may, to the extent permitted by, and subject to compliance with the terms of, the agreement governing the 2024 Revolver and our other indebtedness in existence at such time, settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity.

The issuance or sale of shares of our Class A common stock, or rights to acquire shares of our Class A common stock, could depress the trading price of our Class A common stock and the 2030 Convertible Senior Notes.

We may conduct future offerings of our Class A common stock, preferred stock, or other securities that are convertible into or exercisable for our Class A common stock to finance our operations, fund acquisitions, or for other purposes. The sale of shares of our Class A common stock or other securities that are convertible into or exercisable for our Class A common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Class A common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. In addition, upon conversion of the 2030 Convertible Senior Notes, we will pay consideration that consists of cash, shares of our Class A common stock, or a combination of cash and shares of our Class A common stock (together with cash in lieu of any fractional shares, if applicable), at our election. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of Class A common stock or other securities. We have also reserved 9,500,000 shares of our Class A common stock for issuance under our 2021 Incentive Award Plan (the “2021 Equity Plan”).

The Indenture governing the 2030 Convertible Senior Notes does not restrict our ability to issue additional equity securities. If we issue additional shares of our Class A common stock or rights to acquire shares of our Class A common stock, if any of our existing stockholders sells a substantial amount of our Class A common stock, or if the market perceives that such issuances or sales may occur, then the trading price of our Class A common stock, and, accordingly, the 2030 Convertible Senior Notes may significantly decline. In addition, our issuance of additional shares of Class A common stock will dilute the ownership interests of our existing common stockholders, including noteholders who have received shares of our Class A common stock upon conversion of their 2030 Convertible Senior Notes, and any Class A common stock issued upon conversion of the 2030 Convertible Senior Notes may dilute the interests of our existing common stockholders.

The accounting method for the 2030 Convertible Senior Notes could adversely affect our reported financial condition and results.

The accounting method for reflecting the 2030 Convertible Senior Notes on our balance sheet, accruing interest expense for the 2030 Convertible Senior Notes and reflecting the underlying shares of our Class A common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition.

In accordance with applicable accounting standards, the 2030 Convertible Senior Notes are reflected as a liability on our balance sheets, with the initial carrying amount equal to the principal amount of the 2030 Convertible Senior Notes, net of issuance costs. The issuance costs are treated as a debt discount for accounting purposes, which will be amortized into interest expense over the term of the 2030 Convertible Senior Notes. As a result of this amortization, the interest expense that we expect to recognize for the 2030 Convertible Senior Notes for accounting purposes will be greater than the cash interest payments we will pay on the 2030 Convertible Senior Notes, which will result in lower reported income.

In addition, the potential dilutive shares underlying the 2030 Convertible Senior Notes are reflected in our diluted earnings per share using the “if converted” method. The denominator of diluted earnings per share for the 2030 Convertible Senior Notes is determined by multiplying the principal amount of the 2030 Convertible Senior Notes by the applicable conversion rate for the reporting period. The after-tax interest expense associated with the 2030 Convertible Senior Notes is added back to the numerator of the diluted earnings per share calculation for these purposes. However, if reflecting the 2030 Convertible Senior Notes in diluted earnings per share in this manner is anti-dilutive, then the shares underlying the 2030 Convertible Senior Notes will not be reflected in our diluted earnings per share. The application of the if-converted method may reduce our reported diluted earnings per share, and accounting standards may change in the future in a manner that may adversely affect our diluted earnings per share.

Furthermore, if any of the conditions to the convertibility of the 2030 Convertible Senior Notes is satisfied, then we may be required under applicable accounting standards to reclassify the liability carrying value of the 2030 Convertible Senior Notes as a current, rather than a long-term liability. This reclassification could be required even if no noteholders convert their 2030 Convertible Senior Notes and could materially reduce our reported working capital.

Provisions in the 2030 Convertible Senior Notes and the Indenture governing the 2030 Convertible Senior Notes could delay or prevent an otherwise beneficial takeover of us.

Certain provisions in the 2030 Convertible Senior Notes and its Indenture could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a “fundamental change”, then noteholders will have the right to require us to repurchase their 2030 Convertible Senior Notes for cash. In addition, if a takeover constitutes a “make-whole fundamental change” (as defined in the Indenture), then we may be required to temporarily increase the conversion rate. In either case, and in other cases, our obligations under the 2030 Convertible Senior Notes and the Indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our Class A common stock may view as favorable.

The capped call transactions may affect the value of the 2030 Convertible Senior Notes and our Class A common stock.

In connection with the 2030 Convertible Senior Notes, we entered into privately negotiated capped call transactions with the option counterparties. The capped call transactions cover, subject to customary adjustments, the number of shares of our Class A common stock underlying the 2030 Convertible Senior Notes. The capped call transactions are expected to offset the potential dilution and/or offset any cash payments we are required to make in excess of the principal amount of converted 2030 Convertible Senior Notes, as the case may be, as a result of conversion of the 2030 Convertible Senior Notes, with such offset subject to a cap.

We have been advised that, in connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates entered into various derivative transactions with respect to our Class A common stock and/or purchased shares of our Class A common stock.

In addition, the counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our Class A common stock and/or purchasing or selling our Class A common stock or other securities of ours in secondary market transactions following the pricing of the 2030 Convertible Senior Notes and prior to the maturity of the 2030 Convertible Senior Notes (and are likely to do so (x) during any observation period related to a conversion of the 2030 Convertible Senior Notes or following any redemption or fundamental change repurchase of the 2030 Convertible Senior Notes, (y) following any other repurchase of the 2030 Convertible Senior Notes if we unwind a corresponding portion of the capped call transactions in connection with such repurchase and (z) if we otherwise unwind all or a portion of the capped call transactions). This activity could also cause or avoid an increase or a decrease in the market price of our Class A common stock.

The counterparties to the capped call transactions are financial institutions, or their affiliates, and we will be subject to the risk that one or more of the counterparties may default or otherwise fail to perform, or may exercise certain rights to terminate, their obligations under the capped call transactions. Our exposure to the credit risk of the counterparties is not secured by any collateral.

Global economic conditions have in the past resulted in the actual or perceived potential failure or financial difficulties of many financial institutions. If a counterparty to one or more capped call transactions becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under such transactions. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our Class A common stock increases. In addition, upon a default or other failure to perform, or a termination of obligations, by a counterparty, the counterparty may fail to deliver the shares of common stock required to be delivered to us under the capped call transactions and we may experience adverse tax consequences and more dilution than we currently anticipate with respect to our Class A common stock. We can provide no assurances as to the financial stability or viability of any of the counterparties.
