1. Nature of Operations

Plug Power Inc. (the “Company”, “Plug”, “we” or “our”) is facilitating the paradigm shift to an increasingly electrified world by innovating cutting-edge hydrogen and fuel cell solutions. While we continue to develop commercially viable hydrogen and fuel cell product solutions, we have expanded our offerings to support a variety of commercial operations that can be powered with clean hydrogen. We provide electrolyzers that allow customers — such as refineries, producers of chemicals, steel, fertilizer and commercial refueling stations — to generate hydrogen on-site. We are focusing our efforts on (a) industrial mobility applications, including electric forklifts and electric industrial vehicles, at multi shift high volume manufacturing and high throughput distribution sites where we believe our products and services provide a unique combination of productivity, flexibility, and environmental benefits; (b) production of hydrogen; and (c) stationary power systems that will support critical operations, such as data centers, microgrids, and generation facilities, in either a backup power or continuous power role, and replace batteries, diesel generators or the grid for telecommunication logistics, transportation, and utility customers. Plug expects to support these products and customers with an ecosystem of vertically integrated products that produce, transport, store and handle, dispense, and use hydrogen for mobility and power applications.

Liquidity and Capital Resources

The Company’s working capital was $847.1 million as of September 30, 2024, which included unrestricted cash and cash equivalents of $93.9 million and restricted cash of $906.3 million. On January 17, 2024, the Company entered into the At Market Issuance Sales Agreement (the “Original ATM Agreement”) with B. Riley Securities, Inc. (“B. Riley”), pursuant to which the Company may, from time to time, offer and sell through or to B. Riley, as sales agent or principal, shares of the Company’s common stock, having an aggregate gross sales price of up to $1.0 billion. As of February 23, 2024, the Company had $697.9 million remaining authorized for issuance under the Original ATM Agreement. On February 23, 2024, the Company and B. Riley entered into Amendment No. 1 to the Original ATM Agreement (“Amendment No. 1” and, together with the Original ATM Agreement, the “ATM Agreement”) to increase the aggregate gross sales price of shares of the Company’s common stock available for future issuance under the Original ATM Agreement to $1.0 billion. Under the ATM Agreement, the Company has the right at its sole discretion to direct B. Riley to act on a principal basis and purchase directly from the Company up to $11.0 million of shares of its common stock on any trading day (the “Maximum Commitment Advance Purchase Amount”) if the Company’s market capitalization is more than $1.0 billion (or up to $10.0 million if the Company’s market capitalization is less than $1.0 billion) and up to $55.0 million of shares in any calendar week (the “Maximum Commitment Advance Purchase Amount Cap”) if the Company’s market capitalization is more than $1.0 billion (or up to $30.0 million if the Company’s market capitalization is less than $1.0 billion). As of November 7, 2024, the Company had offered and sold 219,835,221 shares of common stock having an aggregate gross sales price of approximately $677.2 million under the ATM Agreement and shares of the Company’s common stock having an aggregate gross sales price of approximately $624.8 million remained available for issuance and sale under the ATM Agreement.

On November 7, 2024, the Company entered into Amendment No. 2 to the Original ATM Agreement (“Amendment No. 2” and together with the ATM Agreement, the “Amended ATM Agreement”) with B. Riley. Amendment No. 2 increased the aggregate gross sales price of the Company’s common stock the Company may offer and sell pursuant to the Amended ATM Agreement by approximately $375.2 million to $1.0 billion. From and after November 7, 2024, through and including February 7, 2025, the Company has the right at its sole discretion to direct B. Riley to act on a principal basis and purchase from the Company up to the Maximum Commitment Advance Purchase Amount of $11.0 million and up to the Maximum Commitment Advance Purchase Amount Cap of $55.0 million (including any shares sold by B. Riley in agency transactions) in any calendar week. If the Company’s market capitalization is less than $1.0 billion on and after February 8, 2025, the Maximum Commitment Advance Purchase Amount shall be decreased to $10.0 million and the Maximum Commitment Advance Purchase Amount Cap shall be decreased to $30.0 million.

On November 11, 2024, the Company entered into a Debenture Purchase Agreement with YA II PN, Ltd. under which the Company agreed to sell and issue to the Investor an unsecured convertible debenture in aggregate principal amount of $200.0 million in exchange for the payment by the Investor to the Company of $190.0 million. The Company

Table of Contents

expects to close the issuance of the Convertible Debenture on or about November 12, 2024, subject to customary closing conditions. For more information, see Note 24, “Subsequent Events”.

On July 22, 2024, the Company sold 78,740,157 shares of its common stock at a public offering price of $2.54 per share for net proceeds of $191.0 million after deducting the underwriting discount and related offering expenses.

The Company believes that its working capital and cash position, together with its right to direct B. Riley to purchase shares directly from the Company under the Amended ATM Agreement, will be sufficient to fund its on-going operations for a period of at least 12 months subsequent to the issuance of the accompanying unaudited interim condensed consolidated financial statements.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The unaudited interim condensed consolidated financial statements include the financial statements of the Company and its wholly-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. In addition, we include our share of the results of our joint ventures with Renault SAS (“Renault”) named HyVia SAS, a French société par actions simplifiée (“HyVia”), AccionaPlug S.L. (“AccionaPlug”), and SK Plug Hyverse Co., Ltd. (“SK Plug Hyverse”), and our investment in Clean H2 Infra Fund, using the equity method based on our economic ownership interest and our ability to exercise significant influence over the operating and financial decisions of HyVia, AccionaPlug, SK Plug Hyverse and Clean H2 Infra Fund.

Interim Financial Statements

The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, which consist solely of normal recurring adjustments, necessary to present fairly, in accordance with U.S. generally accepted accounting principles (“GAAP”), the financial position, results of operations and cash flows for all periods presented, have been made. The results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for the full year.

Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “2023 Form 10-K”).

The information presented in the accompanying unaudited interim condensed consolidated balance sheets as of December 31, 2023 has been derived from the Company’s 2023 audited consolidated financial statements.

The unaudited interim condensed consolidated financial statements contained herein should be read in conjunction with our 2023 Form 10-K.

Clean Hydrogen Production Tax Credit

Beginning in the second quarter of 2024, the Company determined that it qualifies for the clean hydrogen production tax credit (“PTC”) under Section 45V as part of the Inflation Reduction Act of 2022 (“IRA”) resulting from operation of the Company’s hydrogen production plant located in Georgia. The PTC is available for qualified clean hydrogen produced and sold during the 10-year period beginning on the date the qualified clean hydrogen production facility was originally placed in service. The Company has chosen elective pay, also referred to as direct pay, for the 2024 taxable year. This election makes the PTC refundable, as the Company can receive the full value of the credit from the Internal Revenue Service. This election will apply to the 2024 taxable year and the four subsequent taxable years unless

Table of Contents

revoked. During the remaining five years of the 10-year period to receive the PTC, the Company can elect to transfer all or a portion of the PTC to a third party buyer in exchange for cash. The Company has analogized the accounting of the PTC to accounting for government grants due to the ability to receive payment for the credit regardless of whether the Company has an income tax liability. As a result, the Company recorded approximately $1.6 million and $2.9 million for the three and nine months ended September 30, 2024, respectively, as a reduction to the “fuel delivered to customers and related equipment” costs of revenue financial statement line item in the unaudited interim condensed consolidated statement of operations and $3.3 million as of September 30, 2024 as an increase to the “other assets” financial statement line item in the unaudited interim condensed consolidated balance sheet.

Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

There have been no significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements.

Recent Accounting Guidance Not Yet Effective

Other than the standards mentioned in our 2023 Form 10-K, all issued but not yet effective accounting and reporting standards as of September 30, 2024 are either not applicable to the Company or are not expected to have a material impact on the Company.

3. Extended Maintenance Contracts

On a quarterly basis, we evaluate any potential losses related to our extended maintenance contracts for sales of equipment, related infrastructure and other that have been sold. The following table shows the roll forward of balances in the accrual for loss contracts, including changes due to the provision for loss accrual, releases to service cost of sales, increase to loss accrual related to customer warrants, and foreign currency translation adjustment (in thousands):


	Nine months ended		Year ended

4. Earnings Per Share

Basic earnings per common stock are computed by dividing net loss by the weighted average number of common stock outstanding during the reporting period. Since the Company is in a net loss position, all common stock equivalents would be considered anti-dilutive and are therefore not included in the determination of diluted earnings per share. Accordingly, basic and diluted loss per share are the same.

10. Convertible Senior Notes

7.00% Convertible Senior Notes

On March 20, 2024, the Company entered into separate, privately negotiated exchange agreements with certain holders of the Company’s outstanding 3.75% Convertible Senior Notes pursuant to which the Company exchanged $138.8 million in aggregate principal amount of the 3.75% Convertible Senior Notes, and accrued and unpaid interest of $1.6 million on such notes to, but excluding, March 20, 2024, for $140.4 million in aggregate principal amount of the Company’s new 7.00% Convertible Senior Notes due 2026, in each case, pursuant to the exemption from registration provided by Section 4(a)(2) under the Securities Act of 1933, as amended (the “Securities Act”). Following the exchange, approximately $58.5 million in aggregate principal amount of the 3.75% Convertible Senior Notes remained outstanding with terms unchanged.

This transaction was accounted for as an extinguishment of debt. As a result, the Company recorded a loss on extinguishment of debt of $14.0 million in the unaudited interim condensed consolidated statement of operations during the first quarter of 2024. Loss on extinguishment of debt arises from the difference between the net carrying amount of the Company’s debt and the fair value of the assets transferred to extinguish the debt.

The 7.00% Convertible Senior Notes are the Company’s senior, unsecured obligations and are governed by the terms of an Indenture (the “Indenture”), dated as of March 20, 2024, entered into between the Company and Wilmington Trust, National Association, as trustee. The 7.00% Convertible Senior Notes bear cash interest at the rate of 7.00% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1, 2024, to holders of record at the close of business on the preceding May 15 and November 15, respectively. The 7.00% Convertible Senior Notes mature on June 1, 2026, unless earlier converted or redeemed or repurchased by the Company.

The conversion rate for the 7.00% Convertible Senior Notes is initially 235.4049 shares of the Company’s common stock per $1,000 principal amount of 7.00% Convertible Senior Notes, which is equivalent to an initial conversion price of approximately $4.25 per share of common stock, which represents a premium of approximately 20% over the last reported sale price of Plug’s common stock on the Nasdaq Capital Market on March 12, 2024. The conversion rate and conversion price are subject to customary adjustments upon the occurrence of certain events. Prior to the close of business on the business day immediately preceding December 1, 2025, the 7.00% Convertible Senior Notes will be convertible at the option of the holders of the 7.00% Convertible Senior Notes only upon the satisfaction of specified conditions and during certain periods. On or after December 1, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, the 7.00% Convertible Senior Notes will be convertible at the option of the holders of the 7.00% Convertible Senior Notes at any time regardless of these conditions. Conversions of the 7.00% Convertible Senior Notes will be settled in cash, shares of the Company’s common stock, or a combination thereof, at the Company’s election.

The 7.00% Convertible Senior Notes will be redeemable, in whole or in part, at the Company’s option at any time on or after June 5, 2025, at a cash redemption price equal to the principal amount of the 7.00% Convertible Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the then-applicable conversion price then in effect for at least 20 trading days (whether or not consecutive), including at least one of the three trading days immediately preceding the date the Company sends the related redemption notice, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company sends such redemption notice.

In certain circumstances, conversions of 7.00% Convertible Senior Notes in connection with “Make-Whole Fundamental Changes” (as defined in the Indenture) or conversions of 7.00% Convertible Senior Notes called for redemption may result in an increase to the conversion rate, provided that the conversion rate will not exceed 282.4859 shares of the Company’s common stock per $1,000 principal amount of 7.00% Convertible Senior Notes, subject to adjustment. In such circumstance, a maximum of 39,659,890 shares of common stock, subject to adjustment, may be issued upon conversion of the 7.00% Convertible Senior Notes. There were no conversions of the 7.00% Convertible Senior Notes during the three and nine months ended September 30, 2024.

Capped Call

In conjunction with the pricing of the 3.75% Convertible Senior Notes, the Company entered into privately negotiated capped call transactions (the “3.75% Notes Capped Call”) with certain counterparties at a price of $16.2 million. The 3.75% Notes Capped Call covers, subject to anti-dilution adjustments, the aggregate number of shares of the Company’s common stock that underlie the initial 3.75% Convertible Senior Notes and is generally expected to reduce potential dilution to the Company’s common stock upon any conversion of the 3.75% Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The cap price of the 3.75% Notes Capped Call is initially $6.7560 per share, which represents a premium of approximately 60%over the last then-reported sale price of the Company’s common stock of $4.11 per share on the date of the transaction and is subject to certain adjustments under the terms of the 3.75% Notes Capped Call. The 3.75% Notes Capped Call becomes exercisable if the conversion option is exercised.

The net cost incurred in connection with the 3.75% Notes Capped Call was recorded as a reduction to additional paid-in capital in the unaudited interim condensed consolidated balance sheets at the time the transactions were entered into. The book value of the 3.75% Notes Capped Call is not remeasured.

12. Warrant Transaction Agreements

Amazon Transaction Agreement in 2022

On August 24, 2022, the Company and Amazon entered into a Transaction Agreement (the “2022 Amazon Transaction Agreement”), under which the Company concurrently issued to Amazon.com NV Investment Holdings LLC, a wholly owned subsidiary of Amazon, a warrant (the “2022 Amazon Warrant”) to acquire up to 16,000,000 shares (the “2022 Amazon Warrant Shares”) of the Company’s common stock, subject to certain vesting events described below. The Company and Amazon entered into the 2022 Amazon Transaction Agreement in connection with a concurrent commercial arrangement under which Amazon agreed to purchase hydrogen fuel from the Company through August 24, 2029.

1,000,000 of the 2022 Amazon Warrant Shares vested immediately upon issuance of the 2022 Amazon Warrant. 15,000,000 of the 2022 Amazon Warrant Shares will vest in multiple tranches over the 7-year term of the 2022 Amazon Warrant based on payments made to the Company directly by Amazon or its affiliates, or indirectly through third parties, with 15,000,000 of the 2022 Amazon Warrant Shares fully vesting if Amazon-related payments of $2.1 billion are made in the aggregate. The exercise price for the first 9,000,000 2022 Amazon Warrant Shares is $22.9841 per share and the fair value on the grant date was $20.36. The exercise price for the remaining 7,000,000 2022 Amazon Warrant Shares will be an amount per share equal to 90% of the 30-day volume weighted average share price of the Company’s common stock as of the final vesting event that results in full vesting of the first 9,000,000 2022 Amazon Warrant Shares. The 2022 Amazon Warrant is exercisable through August 24, 2029.

Upon the consummation of certain change of control transactions (as defined in the 2022 Amazon Warrant) prior to the vesting of at least 60% of the aggregate 2022 Amazon Warrant Shares, the 2022 Amazon Warrant will automatically vest and become exercisable with respect to an additional number of 2022 Amazon Warrant Shares such that 60% of the aggregate 2022 Amazon Warrant Shares shall have vested. If a change of control transaction is consummated after the vesting of at least 60% of the aggregate 2022 Amazon Warrant Shares, then no acceleration of vesting will occur with respect to any of the unvested 2022 Amazon Warrant Shares as a result of the transaction. The exercise price and the 2022 Amazon Warrant Shares issuable upon exercise of the 2022 Amazon Warrant are subject to customary antidilution adjustments.

On August 24, 2022, 1,000,000 of the 2022 Amazon Warrant Shares associated with tranche 1 vested. The warrant fair value associated with the vested shares of tranche 1 of $20.4 million was capitalized to contract assets based on the grant date fair value and is subsequently amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement. As of September 30, 2024, the balance of the contract asset related to tranche 1 was $18.8 million which is recorded in contract assets in the Company’s unaudited interim condensed consolidated balance sheet. During the second quarter of 2023, all 1,000,000 of the 2022 Amazon Warrant Shares associated with tranche 2 vested. The warrant fair value associated with the vested shares of tranche 2 was $20.4 million and was determined on the grant date of August 24, 2022. As of September 30, 2024, the balance of the contract asset related to tranche 2 was $18.8 million. Tranche 3 will vest over the next $1.0 billion of collections from Amazon and its affiliates. The grant date fair value of tranche 3 will also be amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement. As of September 30, 2024, the balance of the contract asset related to tranche 3 was $3.6 million. Because the exercise price has yet to be determined, the fair value of tranche 4 will be remeasured at each reporting period end and amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement.

As of September 30, 2024 and December 31, 2023, 2,500,000 and 2,000,000 of the 2022 Amazon Warrant Shares had vested, respectively, and none of the 2022 Amazon Warrant Shares had been exercised. The total amount of provision for common stock warrants recorded as a reduction of revenue for the 2022 Amazon Warrant during the three months ended September 30, 2024 and 2023 was $2.0 million and $1.6 million, respectively. The total amount of provision for common stock warrants recorded as a reduction of revenue for the 2022 Amazon Warrant during the nine months ended September 30, 2024 and 2023 was $4.4 million and $4.3 million, respectively.

Walmart Transaction Agreement

On July 20, 2017, the Company and Walmart entered into a Transaction Agreement (the “Walmart Transaction Agreement”), pursuant to which the Company agreed to issue to Walmart a warrant (the “Walmart Warrant”) to acquire up to 55,286,696 shares of the Company’s common stock, subject to certain vesting events (the “Walmart Warrant Shares”). The Company and Walmart entered into the Walmart Transaction Agreement in connection with existing commercial agreements between the Company and Walmart with respect to the deployment of the Company’s GenKey fuel cell technology across various Walmart distribution centers. The existing commercial agreements contemplate, but do not guarantee, future purchase orders for the Company’s fuel cell technology. The vesting of the warrant shares was conditioned upon payments made by Walmart or its affiliates (directly or indirectly through third parties) pursuant to transactions entered into after January 1, 2017 under existing commercial agreements.

The exercise price for the first and second tranches of Walmart Warrant Shares was $2.1231 per share. After Walmart has made payments to the Company totaling $200.0 million, the third tranche of 20,368,784 Walmart Warrant Shares will vest in eight installments of 2,546,098 Walmart Warrant Shares each time Walmart or its affiliates, directly or indirectly through third parties, make an aggregate of $50.0 million in payments for goods and services to the Company, up to payments totaling $400.0 million in the aggregate. The exercise price of the third tranche of the Walmart Warrant Shares is $6.28 per share, which was determined pursuant to the terms of the Walmart Warrant as an amount equal to 90% of the 30-day volume weighted average share price of the Company’s common stock as of October 30, 2023, the final vesting date of the second tranche of the Walmart Warrant Shares. The Walmart Warrant is exercisable through July 20, 2027. The Walmart Warrant provides for net share settlement that, if elected by the holder, will reduce the number of shares issued upon exercise to reflect net settlement of the exercise price. The Walmart Warrant provides for certain adjustments that may be made to the exercise price and the number of shares of common stock issuable upon exercise due to customary anti-dilution provisions based on future events. The Walmart Warrant is classified as an equity instrument. As of September 30, 2024, the balance of the contract asset related to the Walmart Warrant was $5.4 million.

As of September 30, 2024 and December 31, 2023, 40,010,108 and 34,917,912 of the Walmart Warrant Shares had vested, respectively, and the Walmart Warrant was exercised with respect to 13,094,217 shares of the Company’s common stock. During the three and nine months ended September 30, 2024 and 2023, there were no exercises with respect to the Walmart Warrant. The total amount of provision for common stock warrants recorded as a reduction of revenue for the Walmart Warrant during the three months ended September 30, 2024 was $3.9 million compared to a negative provision for common stock warrants recorded as an addition to revenue of $3.1 million for the three months ended September 30, 2023. The total amount of provision for common stock warrants recorded as a reduction of revenue for the Walmart Warrant during the nine months ended September 30, 2024 and 2023 was $11.6 million and $8.4 million, respectively.

Contract assets primarily relate to contracts for which revenue is recognized on a straight-line basis; however, billings escalate over the life of a contract. Contract assets also include amounts recognized as revenue in advance of billings to customers, which are dependent upon the satisfaction of another performance obligation. These amounts are included in contract assets on the accompanying unaudited interim condensed consolidated balance sheets.

The deferred revenue and contract liabilities relate to the advance consideration received from customers for services that will be recognized over time (primarily fuel cell and related infrastructure services and electrolyzer systems and solutions). Deferred revenue and contract liabilities also include advance consideration received from customers prior to delivery of products. These amounts are included within deferred revenue and other contract liabilities on the unaudited interim condensed consolidated balance sheets.

14. Income Taxes

The Company recorded $0.1 million of income tax expense and $4.7 million of income tax benefit for the three months ended September 30, 2024 and 2023, respectively. The Company recorded $0.1 million of income tax benefit and $6.9 million of income tax benefit for the nine months ended September 30, 2024 and 2023, respectively. The income tax benefit for the nine months ended September 30, 2024 was due to an incremental change to the valuation allowance recorded in foreign jurisdictions. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its domestic net deferred tax assets, which remain fully reserved, and its valuation allowances recorded in foreign jurisdictions.

be realized. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.

The Organization for Economic Co-operation and Development Inclusive Framework on Base Erosion and Profit Shifting has proposed a global minimum corporate tax rate of 15% on multi-national corporations, commonly referred to as the Pillar Two rules that has been agreed upon in principle by over 140 countries. While the United States has not adopted the Pillar Two rules, numerous foreign countries have enacted legislation to implement the Pillar Two rules, effective beginning January 1, 2024, or are expected to enact similar legislation. As of September 30, 2024, the Company did not meet the consolidated revenue threshold and is not subject to the GloBE Rules under Pillar Two. The Company will continue to monitor the implementation of rules in the jurisdictions in which it operates.

15. Fair Value Measurements

The Company records the fair value of assets and liabilities in accordance with ASC 820, Fair Value Measurement (“ASC 820”). ASC 820 defines fair value as the price received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity.

In addition to defining fair value, ASC 820 expands the disclosure requirements around fair value and establishes a fair value hierarchy for valuation inputs. The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of the three levels, which is determined by the lowest level input that is significant to the fair value measurement in its entirety.

These levels are:

●

Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities.

●

Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.

●

Level 3 — unobservable inputs reflecting management’s own assumptions about the inputs used in pricing the asset or liability at fair value.

There were no transfers between Level 1, Level 2, or Level 3 during the nine months ended September 30, 2024. Financial instruments not recorded at fair value on a recurring basis include equity method investments that have not been remeasured or impaired in the current period, such as our investments in HyVia, AccionaPlug, SK Plug Hyverse and Clean H2 Infra Fund.

Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands):


		As of September 30, 2024
		Carrying		Fair		Fair Value Measurements

The liabilities measured at fair value on a recurring basis that have unobservable inputs and are therefore categorized as level 3 are related to contingent consideration. The fair value as of September 30, 2024 of $92.0 million is comprised of contingent consideration related to the Joule Processing LLC (“Joule”) acquisition in 2022 and the Frames Holding B.V. (“Frames”) acquisition in 2021.

Table of Contents

In connection with the Joule acquisition, the Company initially recorded on its unaudited interim condensed consolidated balance sheet a liability of $41.7 million representing the fair value of contingent consideration payable. The fair value of this contingent consideration was $60.0 million and $75.5 million as of September 30, 2024 and December 31, 2023, respectively. The decrease compared to the year ended December 31, 2023 was primarily due to payments that reduced the fair value of the liability by $10.0 million during the first quarter of 2024 and by $57 thousand during the third quarter of 2024. A decrease of $1.4 million and $5.5 million was recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the three and nine months ended September 30, 2024, respectively.

In connection with the Frames acquisition, the Company initially recorded on its unaudited interim condensed consolidated balance sheet a liability of $29.1 million representing the fair value of contingent consideration payable. The fair value of this contingent consideration was $32.0 million and $31.8 million as of September 30, 2024 and December 31, 2023, respectively. The increase compared to the year ended December 31, 2023 was primarily due to an increase in foreign currency translation losses of $1.3 million and $0.3 million for the three and nine months ended September 30, 2024, respectively. The increase was partially offset by a decrease of $0.1 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the nine months ended September 30, 2024, partially offset by an increase of $1.5 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the three months ended September 30, 2024.

In connection with the United Hydrogen Group Inc. (“UHG”) acquisition, the Company initially recorded on its unaudited interim condensed consolidated balance sheet a liability of $1.1 million representing the fair value of contingent consideration payable. The contingent consideration was fully settled during the second quarter of 2024 and the fair value of this contingent consideration was $0.9 million as of December 31, 2023. The decrease of $0.9 million was due to payments that reduced the fair value of the liability by $1.0 million during the second quarter of 2024. Partially offsetting this decrease was an increase of $0.1 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations during the nine months ended September 30, 2024. The $1.0 million payment made during the second quarter of 2024 settled the remaining earn-out obligation.

In connection with the Giner acquisition, the Company initially recorded on its unaudited interim condensed consolidated balance sheet a liability of $16.0 million representing the fair value of contingent consideration payable. The contingent consideration was fully settled during the second quarter of 2024 and the fair value of this contingent consideration was $18.0 million as of December 31, 2023. The decrease of $18.0 million was due to payments that reduced the fair value of the liability by $18.2 million during the second quarter of 2024. Partially offsetting this decrease was an increase of $0.2 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations during the nine months ended September 30, 2024. The $18.2 million payment during the second quarter of 2024 was paid in common stock and warrants and settled the remaining obligation of the earn-out. As part of the $18.2 million settlement of Giner’s earn-out obligation on May 24, 2024, the Company issued warrants to the sellers of Giner and the Company registered for resale up to 3,461,371 shares of the Company’s common stock issuable upon exercise of the warrants. The warrants had not been exercised as of September 30, 2024.

In the unaudited interim condensed consolidated balance sheets, contingent consideration is recorded in the contingent consideration, loss accrual for service contracts, and other current liabilities financial statement line item, and was comprised of the following unobservable inputs as of September 30, 2024:


Financial Instrument	Fair Value		Valuation Technique	Unobservable Input	Range (weighted average)

17. Operating and Finance Lease Liabilities

As of September 30, 2024, the Company had operating leases, as lessee, primarily associated with sale/leaseback transactions that are partially secured by restricted cash and security deposits (see also Note 19, “Commitments and Contingencies”) as summarized below. These leases expire over the next one to seven years. Minimum rent payments under operating leases are recognized on a straight-line basis over the term of the lease.

Leases contain termination clauses with associated penalties, the amount of which cause the likelihood of cancellation to be remote. At the end of the lease term, the leased assets may be returned to the lessor by the Company, the Company may negotiate with the lessor to purchase the assets at fair market value, or the Company may negotiate with the lessor to renew the lease at market rental rates. No residual value guarantees are contained in the leases. No financial covenants are contained within the lease; however, the lease contains customary operational covenants such as the requirement that the Company properly maintain the leased assets and carry appropriate insurance. The leases include credit support in the form of either cash, collateral or letters of credit. See Note 19, “Commitments and Contingencies”, for a description of cash held as security associated with the leases.

The Company has finance leases associated with its property and equipment in Slingerlands, New York and at customer fueling locations.

Litigation

Legal matters are handled in the ordinary course of business. The outcome of any such matters, regardless of the merits, is inherently uncertain; therefore, assessing the likelihood of loss and any estimated damages is difficult and subject to considerable judgment. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably

Table of Contents

estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. While we are not in a position to accurately predict the outcome of any legal or other proceedings, where there is at least a reasonable possibility that a loss may be incurred, GAAP requires us to disclose an estimate of the reasonably possible loss or range of loss, if material, or make a statement that such an estimate cannot be made. Except for a $0.6 million accrual relating to a settled matter subject to pending court approval, which has not been paid as of September 30, 2024, a reasonably possible loss or range of loss associated with any individual legal proceeding cannot be currently estimated.

Securities Litigation and Related Stockholder Derivative Litigation

2021 Securities Action and Related Derivative Litigation

One action is pending in which alleged stockholders of the Company assert claims derivatively, on the Company’s behalf, based on allegations and claims that were asserted in In re Plug Power, Inc. Securities Litigation, No. 1:21-cv-2004 (S.D.N.Y.), an earlier putative securities class action that is no longer pending (the “2021 Securities Action”). In an opinion and order entered in August 2023, the district court dismissed the 2021 Securities Action with prejudice, and the plaintiffs in that action did not appeal.

A consolidated stockholder derivative action relating to the claims and allegations in the 2021 Securities Action is pending in the Court of Chancery for the State of Delaware, styled In re Plug Power Inc. Stockholder Derivative Litigation, Cons. C.A. No. 2022-0569-KSJM (Del. Ch.). By stipulation and order, the action was stayed until motions to dismiss were finally resolved in the 2021 Securities Action. On March 8, 2024, the alleged stockholder plaintiffs filed a consolidated amended complaint asserting claims against our officers Andrew J. Marsh, Paul B. Middleton, Gerard L. Conway, Jr., and Keith Schmid, and against our current or former directors George C. McNamee, Gary K. Willis, Maureen O. Helmer, Johannes M. Roth, Gregory L. Kenausis, Lucas Schneider, and Jonathan Silver. The Company is named as nominal defendant. Primarily based on allegations in the 2021 Securities Action, the plaintiffs assert claims against the individual defendants for alleged breaches of fiduciary duty, disgorgement, and unjust enrichment based on alleged transactions in the Company’s securities while allegedly in possession of material non-public information concerning (i) the Company’s financial accounting prior to the announcement that the Company would need to restate certain financial statements and (ii) the potential amendment and termination of a warrant agreement between the Company and a significant customer. On May 10, 2024, the Company, as nominal defendant, and all of the individual defendants filed a motion to dismiss (a) for failure to make a pre-suit demand or to adequately allege demand futility and (b) by the individual defendants, for failure to state a claim. Oral argument on the motion was held on November 4, 2024.

2023 Securities Action and Related Derivative Litigation

A consolidated action is pending in the United States District Court for the District of Delaware asserting claims under the federal securities laws against the Company and certain of its senior officers on behalf of a putative class of purchasers of the Company’s securities, styled In re Plug Power, Inc. Securities Litigation, No. 1:23-cv-00576-MN (the “2023 Securities Action”). The plaintiffs filed a consolidated complaint on September 28, 2023, in which they assert claims under the federal securities laws against the Company and four of its senior officers, Mr. Marsh, Mr. Middleton, Sanjay Shrestha, and former officer David Mindnich, on behalf of a putative class of purchasers of the Company’s common stock between January 19, 2022 and March 1, 2023. The complaint alleges that the defendants made “materially false and/or misleading statements” about the Company’s business and operations, including the Company’s revenue goals for 2022, its ability to effectively manage its supply chain and product manufacturing, and its progress in construction of new hydrogen production capacity. The defendants filed a motion to dismiss the complaint on December 14, 2023, and briefing was completed in March 2024. All proceedings are stayed pending resolution of the motion to dismiss.

Beginning on September 13, 2023, three separate actions were filed in the U.S. District Court for the District of Delaware and in the U.S. District Court for the Southern District of New York asserting claims derivatively, on behalf of the Company, against certain former and current Company officers and directors based on the allegations and claims in the 2023 Securities Action. Those cases have been consolidated in the District of Delaware under the caption In re Plug Power, Inc. Stockholder Deriv. Litig., No. 1:23-cv-01007-MN (D. Del.). The defendants named in the constituent complaint were Mr. Marsh, Mr. Middleton, Mr. Mindnich, Martin Hull, Ms. Helmer, Mr. Kenausis, Mr. McNamee, Mr.

Table of Contents

Schneider, Mr. Silver, Mr. Willis, and current or former directors Jean Bua, Kavita Mahtani, and Kyungyeol Song. In an order entered on April 26, 2024, the Court approved the parties’ stipulation to stay all proceedings until motions to dismiss have been resolved in the 2023 Securities Action.

2024 Securities Litigation

On March 22, 2024, Ete Adote filed a complaint in the United States District Court for the Northern District of New York asserting claims under the federal securities laws against the Company, Mr. Marsh, and Mr. Middleton, on behalf of an alleged class of purchasers of the Company’s common stock between May 9, 2023 and January 16, 2024, styled Adote v. Plug Power, Inc. et al., No. 1:24-cv-00406-MAD-DJS (N.D.N.Y.). The complaint alleges that the defendants made misstatements concerning the Company’s progress in construction of new hydrogen production capacity and its ability to effectively manage its supply chain. On April 30, 2024, a second complaint asserting substantially similar claims against the same defendants, but on behalf of a putative class of purchasers of the Company’s common stock between March 1, 2023 and January 16, 2024, was filed in the Northern District of New York, styled Lee v. Plug Power, et al., No. 1:24;cv-0598-MAD-DJS (N.D.N.Y.). The Court has approved stipulations in both actions extending the time for all defendants to respond to any pleading until after the Court appoints lead plaintiff(s).

Other Litigation

On May 2, 2023, a lawsuit entitled Jacob Thomas and JTurbo Engineering & Technology, LLC v. Joule Processing, LLC and Plug Power Inc., Case No. 4:23-cv-01615, was filed in the United States District Court for the Southern District of Texas against Joule Processing, LLC and the Company. The only claims that remain are misappropriation of trade secrets under the federal Defend Trade Secrets Act of 2016, 18 U.S.C. § 1836, misappropriation of trade secrets under the Texas Uniform Trade Secrets Act, and breach of contract. Currently pending before the United States District Court for the Southern District of Texas is Plaintiff[s’] Verified Amended Application for Temporary Restraining Order, Preliminary Injunction and Permanent Injunctive Relief, which was filed on November 17, 2023. Also pending is Defendants Joule Processing, LLC’s and the Company’s Motion for Summary Judgment, which was filed on August 19, 2024, and Plaintiffs’ Amended Motion for Partial Summary Judgment, which was filed on October 1, 2024.

On July 24, 2023, an action entitled Felton v. Plug Power, Inc., Case No. 1:23-cv-887, was filed in the U.S. District Court for the Northern District of New York asserting claims against the Company pursuant to the New York State Human Rights Law. The complaint asserts that the plaintiff is seeking damages to redress injuries suffered as a result of harassment and discrimination on the basis of his race, together with creating a hostile work environment, and retaliation. The Company disagrees with plaintiff’s representations about his time at the Company and intends to vigorously defend against his allegations. Plaintiff’s counsel moved to withdraw from the case, which the court approved on March 18, 2024, and therefore plaintiff is now pro se. The current discovery deadline is January 31, 2025.

On October 23, 2024, a case entitled First Solar, Inc. v. Plug Power Inc., Index No. 655610/2024 was filed in the New York State Supreme Court, New York County, asserting a claim for breach of contract associated with a purchase order for solar panels manufactured by First Solar to be purchased by the Company. The complaint seeks monetary relief along with pre-judgment interest.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, restricted cash and accounts receivable. Cash and restricted cash are maintained in accounts with financial institutions, which, at times may exceed the Federal depository insurance coverage of $250 thousand. The Company has not experienced losses on these accounts and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant.

Concentrations of credit risk with respect to receivables exist due to the limited number of select customers with whom the Company has commercial sales arrangements. To mitigate credit risk, the Company performs appropriate evaluation of a prospective customer’s financial condition.

Table of Contents

As of September 30, 2024, one customer individually exceeded 10% of total consolidated accounts receivable balance with a balance of $34.1 million, or 20.4%, of the Company’s consolidated accounts receivable balance. At December 31, 2023, one customer individually exceeded 10% of total consolidated accounts receivable balance with a balance of $52.4 million, or 21.5%, of the Company’s consolidated accounts receivable balance.

For purposes of assigning a customer to a sale/leaseback transaction completed with a financial institution, the Company considers the end user of the assets to be the ultimate customer. For the three months ended September 30, 2024, two customers individually exceeded 10% of total consolidated revenues. One of the customers accounted for $29.0 million, or 16.7%, and one of the customers accounted for $24.6 million, or 14.2%, of total consolidated revenues. For the three months ended September 30, 2023, three customers individually exceeded 10% of total consolidated revenues. One of the customers accounted for $35.1 million, or 17.7%, one of the customers accounted for $30.7 million, or 15.4%, and one of the customers accounted for $22.2 million, or 11.2%, of total consolidated revenues.

For the nine months ended September 30, 2024, two customers individually exceeded 10% of total consolidated revenues.

Guarantee

On May 30, 2023, our joint venture, HyVia, entered into a government grant agreement with Bpifrance. As part of the agreement, our wholly-owned subsidiary, Plug Power France, was required to issue a guarantee to Bpifrance in the amount of €20 million through the end of January 2027. Plug Power France is liable to the extent of the guarantee for sums due to Bpifrance from HyVia under the agreement based on the difference between the total amount paid by Bpifrance and the final amount certified by HyVia and Bpifrance. As part of the agreement, there are certain milestones that HyVia is required to meet, and the nonperformance of these milestones or termination of this agreement could result in this guarantee being called upon. As of September 30, 2024, no payments related to this guarantee have been made by the Company and Plug Power France did not record a liability for this guarantee as the likelihood of the guarantee being called upon is remote.

Unconditional Purchase Obligations

The Company has entered into certain off–balance sheet commitments that require the future purchase of goods or services (“unconditional purchase obligations”). The Company’s unconditional purchase obligations primarily consist of supplier arrangements, take or pay contracts and service agreements. For certain vendors, the Company’s unconditional obligation to purchase a minimum quantity of raw materials at an agreed upon price is fixed and determinable; while certain other raw material costs will vary due to product forecasting and future economic conditions.

Future payments under non-cancelable unconditional purchase obligations with a remaining term in excess of one year as of September 30, 2024, were as follows (in thousands):

21. Segment and Geographic Area Reporting

Our organization is managed from a sales perspective based on “go-to-market” sales channels, emphasizing shared learning across end-user applications and common supplier/vendor relationships. These sales channels are structured to serve a range of customers for our products and services. As a result of this structure, we concluded that we have one operating and reportable segment — the design, development and sale of hydrogen products and solutions that help customers meet their business goals while decarbonizing their operations. Our chief executive officer was identified as the chief operating decision maker (CODM). All significant operating decisions made by management are largely based upon the analysis of Plug Power Inc. on a total company basis, including assessments related to our incentive compensation plans.

23. Restructuring

In February 2024, in a strategic move to enhance our financial performance and ensure long-term value creation in a competitive market, we approved a comprehensive initiative that encompasses a broad range of measures, including operational consolidation, strategic workforce adjustments, and various other cost-saving actions (the “Restructuring Plan”). These measures are aimed at increasing efficiency, improving scalability, and maintaining our leadership position in the renewable energy industry. We began executing the Restructuring Plan in February 2024 and expect the Restructuring Plan to be completed in the fourth quarter of 2024, subject to local law and consultation requirements.

The determination of when we accrue for involuntary termination benefits under restructuring plans depends on whether the termination benefits are provided under an ongoing benefit arrangement or under a one-time benefit arrangement. We account for involuntary termination benefits that are provided pursuant to one-time benefit arrangements in accordance with ASC 420, Exit or Disposal Cost Obligations (“ASC 420”) whereas involuntary termination benefits that are part of an ongoing written or substantive plan are accounted for in accordance with ASC 712, Nonretirement Postemployment Benefits (“ASC 712”). We accrue a liability for termination benefits under ASC 420 in the period in which the plan is communicated to the employees and the plan is not expected to change significantly. For ongoing benefit arrangements, inclusive of statutory requirements, we accrue a liability for termination benefits under ASC 712 when the existing situation or set of circumstances indicates that an obligation has been incurred, it is probable the benefits will be paid, and the amount can be reasonably estimated. The restructuring charges that have been incurred but not yet paid are recorded in accrued expenses and other current liabilities in our unaudited interim condensed consolidated balance sheets, as they are expected to be paid within the next twelve months.

During the three months ended September 30, 2024, we incurred $0.6 million in restructuring costs recorded as severance expenses of $0.1 million and other restructuring costs of $0.5 million in the restructuring financial statement line item in the unaudited interim condensed consolidated statement of operations. During the nine months ended September 30, 2024, we incurred $8.2 million in restructuring costs recorded as severance expenses of $6.9 million and other restructuring costs of $1.3 million in the restructuring financial statement line item in the unaudited interim condensed consolidated statement of operations. Future restructuring costs are not expected to be material in subsequent quarters. The actual timing and amount of costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material.

Severance expense recorded during the three and nine months ended September 30, 2024 in accordance with ASC 420 was a result of the separation of full-time employees associated with the Restructuring Plan. As of September 30, 2024, $0.1 million of accrued severance-related costs were included in accrued expenses in our unaudited interim condensed consolidated balance sheets and are expected to be paid during the fourth quarter of 2024. For the three months ended September 30, 2024, other costs were represented by $0.5 million of other one-time employee termination benefits. For the nine months ended September 30, 2024, other costs were represented by (1) $0.2 million of legal and professional services costs, and (2) $1.1 million of other one-time employee termination benefits. As of September 30, 2024, $29 thousand of accrued other costs were included in accrued expenses in our unaudited interim condensed consolidated balance sheets and are expected to be paid during the fourth quarter of 2024.

Overview

Plug is facilitating the paradigm shift to an increasingly electrified world by innovating cutting-edge hydrogen and fuel cell solutions.

While we continue to develop commercially viable hydrogen and fuel cell product solutions, we have expanded our offerings to support a variety of commercial operations that can be powered with clean hydrogen. We provide electrolyzers that allow customers — such as refineries, producers of chemicals, steel, fertilizer and commercial refueling stations — to generate hydrogen on-site. We are focusing our efforts on (a) industrial mobility applications, including electric forklifts and electric industrial vehicles, at multi shift high volume manufacturing and high throughput distribution sites where we believe our products and services provide a unique combination of productivity, flexibility, and environmental benefits; (b) production of hydrogen; and (c) stationary power systems that will support critical operations, such as data centers, microgrids, and generation facilities, in either a backup power or continuous power role, and replace batteries, diesel generators or the grid for telecommunication logistics, transportation, and utility customers. Plug expects to support these products and customers with an ecosystem of vertically integrated products that produce, transport, store and handle, dispense, and use hydrogen for mobility and power applications.

Our current product and service portfolio includes:

GenDrive: GenDrive is our hydrogen fueled PEM fuel cell system, providing power to material handling electric vehicles (“EVs”), including Class 1, 2, 3 and 6 electric forklifts, automated guided vehicles, and ground support equipment.

GenSure: GenSure is our stationary fuel cell solution providing scalable, modular PEM fuel cell power to support the backup and grid-support power requirements of the telecommunications, transportation, and utility sectors; our GenSure High Power Fuel Cell Platform supports large scale stationary power and data center markets.

ProGen: ProGen is our fuel cell stack and engine technology currently used globally in mobility and stationary fuel cell systems, and as engines in electric delivery vans. This includes Plug’s membrane electrode assembly (“MEA”), a critical component of the fuel cell stack used in zero-emission fuel cell EV engines.

GenFuel: GenFuel is our liquid hydrogen fueling, delivery, generation, storage, and dispensing system.

GenCare: GenCare is our ongoing “Internet of Things”-based maintenance and on-site service program for GenDrive fuel cell systems, GenSure fuel cell systems, GenFuel hydrogen storage and dispensing products and ProGen fuel cell engines.

GenKey: GenKey is our vertically integrated “turn-key” solution combining either GenDrive or GenSure fuel cell power with GenFuel fuel and GenCare aftermarket service, offering complete simplicity to customers transitioning to fuel cell power.

Electrolyzers: The design and implementation of 5MW and 10MW electrolyzer systems that are modular, scalable hydrogen generators optimized for clean hydrogen production. Electrolyzers generate hydrogen from water using electricity and a special membrane and “green” hydrogen is generated by using renewable energy inputs, such as solar or wind power.

Liquefaction Systems: Plug’s 15 ton-per-day and 30 ton-per-day liquefiers are engineered for high efficiency, reliability, and operational flexibility — providing consistent liquid hydrogen to customers. This design increases plant reliability and availability while minimizing parasitic losses like heat leak and seal gas losses.

Table of Contents

Cryogenic Equipment: Engineered equipment including trailers and mobile storage equipment for the distribution of liquified hydrogen, oxygen, argon, nitrogen and other cryogenic gases.

Liquid Hydrogen: Liquid hydrogen provides an efficient fuel alternative to fossil-based energy. We produce liquid hydrogen through our electrolyzer systems and liquefaction systems. Liquid hydrogen supply will be used by customers in material handling operations, fuel cell electric vehicle fleets, and stationary power applications.

We provide our products and solutions worldwide through our direct sales force, and by leveraging relationships with original equipment manufacturers (“OEMs”) and their dealer networks. Plug is currently targeting Asia, Australia, Europe, Middle East and North America for expansion in adoption. The European Union has rolled out ambitious targets for the hydrogen economy, with the United Kingdom also taking steps in this direction, and Plug is seeking to execute on our strategy to become one of the European leaders in the hydrogen economy. This includes a targeted account strategy for material handling, securing strategic partnerships with European OEMs, energy companies, utility leaders and accelerating our electrolyzer business.

We manufacture our commercially viable products in Latham, New York; Rochester, New York; Slingerlands, New York; Houston, Texas; Lafayette, Indiana; and Spokane, Washington, and support liquid hydrogen production and logistics in Charleston, Tennessee and Kingsland, Georgia.

Results of Operations

Our primary sources of revenue are from sales of equipment, related infrastructure and other, services performed on fuel cell systems and related infrastructure, power purchase agreements, and fuel delivered to customers and related equipment. A certain portion of our sales result from acquisitions in legacy markets, which we are working to transition to renewable solutions. Revenue from sales of equipment, related infrastructure and other represents sales of our GenDrive units, GenSure stationary backup power units, cryogenic stationary and on road storage, hydrogen liquefaction systems, electrolyzers and hydrogen fueling infrastructure. Revenue from services performed on fuel cell systems and related infrastructure represents revenue earned on our service and maintenance contracts and sales of spare parts. Revenue from power purchase agreements primarily represent payments received from customers who make monthly payments to access the Company’s GenKey solution. Revenue associated with fuel delivered to customers and related equipment represents the sale of hydrogen to customers that has been purchased by the Company from a third party or generated at our hydrogen production plant.

including general management, finance and accounting, human resources, selling and marketing, information technology and legal services.

The decrease was primarily due to a decrease in stock compensation as certain market-condition awards near the end of their vesting period as well as stock compensation forfeitures.

Selling, general and administrative expenses for the nine months ended September 30, 2024 decreased $55.9 million, or 18.0%, to $254.7 million from $310.6 million for the nine months ended September 30, 2023. The decrease was primarily due to a decrease in stock compensation expense related to stock compensation forfeitures resulting from the Restructuring Plan announced in February 2024 as well as certain market-condition awards nearing the end of their vesting period.

Restructuring. Expenses related to the Restructuring Plan for the three months ended September 30, 2024 was $0.5 million. The increase was due to severance and benefits related to the Restructuring Plan the Company announced in February 2024.

Expenses related to the Restructuring Plan for the nine months ended September 30, 2024 was $8.2 million. The increase was due to severance and benefits related to the Restructuring Plan the Company announced in February 2024.

Impairment. Impairment for the three months ended September 30, 2024 increased $3.5 million, or 500.0%, to $4.2 million from $0.7 million for the three months ended September 30, 2023. The increase was primarily related to the Company recording a higher impairment charge on long-lived assets due to the cancellation of certain projects during the three months ended September 30, 2024.

Impairment for the nine months ended September 30, 2024 decreased $3.3 million, or 28.2%, to $8.4 million from $11.7 million for the nine months ended September 30, 2023.

Change in fair value of contingent consideration. The change in fair value of contingent consideration is related to earnouts for the Joule Processing LLC (“Joule”) and Frames Holding B.V. (“Frames”) acquisitions. The change in fair value of contingent consideration for the three months ended September 30, 2024 and 2023 was $0.1 million and $2.2 million, respectively. The decrease was primarily due to the Giner ELX, Inc. (“Giner”) and Universal Hydrogen Group Inc. (“UHG”) earn-outs that were still outstanding during the three months ended September 30, 2023 but subsequently settled during the second quarter of 2024. In addition, the fair value of contingent consideration for Joule’s earn-out increased by $2.9 million during the three months ended September 30, 2023 due to passage of time.

The change in fair value of contingent consideration for the nine months ended September 30, 2024 and 2023 was ($5.3) million and $26.3 million, respectively. The decrease was primarily due to changes in assumptions related to future earn-out payments due to renegotiated agreements during the first quarter of 2024 as well as the settlement of the UHG and Giner earn-outs.

Interest income. Interest income primarily consists of income generated by our investment holdings, restricted cash escrow accounts, and money market accounts.

The decrease during the three months ended September 30, 2024 compared to September 30, 2023 was primarily due to the maturities and sale of the Company’s available-for-sale portfolio of higher-yielding U.S. treasury securities during 2023.

Interest income for the nine months ended September 30, 2024 decreased $19.9 million compared to the nine months ended September 30, 2023.

Other-than-temporary impairment of available-for-sale securities. For the three and nine months ended September 30, 2023, the Company recorded an other-than-temporary impairment charge of $10.8 million on the Company's available-for-sale securities due to a change in the Company's ability and intent to retain the investments for a period of time sufficient to allow for any anticipated recovery in the fair value. The other-than-temporary charge was realized when the Company sold its remaining available-for-sale securities and equity securities during the fourth quarter of 2023.

These losses are driven from the start-up activities for commercial and production operations of the aforementioned investments.

Loss on extinguishment of convertible senior notes. Loss on extinguishment of convertible senior notes arises from the difference between the net carrying amount of the Company’s Convertible Senior Notes and the fair value of the assets transferred to extinguish the Convertible Senior Notes. For the three months ended September 30, 2024 and September 30, 2023, the Company did not record a loss on extinguishment of convertible senior notes.

For the nine months ended September 30, 2024, the Company recorded a loss of $14.0 million on extinguishment of convertible senior notes. These losses are driven from the exchange of $138.8 million in aggregate principal amount of

Income Taxes

The domestic net deferred tax asset generated from the Company’s net operating loss has been offset by a full valuation allowance because it is more likely than not that the tax benefits of the net operating loss carryforward will not be realized. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.

Liquidity and Capital Resources

As of September 30, 2024 and December 31, 2023, the Company had $93.9 million and $135.0 million, respectively, of cash and cash equivalents and $906.3 million of restricted cash as of September 30, 2024.

Operating Activities

The net cash used in operating activities for the nine months ended September 30, 2024 and 2023 was $597.4 million and $863.9 million, respectively. This decrease in net cash used in operating activities was primarily due to cash inflows related to the Company’s accounts receivables and inventory, partially offset by an increase in net loss, a decrease in accounts payable, accrued expenses, and other liabilities and a decrease in deferred revenue and other contract liabilities.

Financing Activities

The net cash provided by financing activities for the nine months ended September 30, 2024 and 2023 was $779.2 million and $14.4 million, respectively.

During the second quarter of 2023, all 1,000,000 of the 2022 Amazon Warrant Shares associated with tranche 2 vested. The warrant fair value associated with the vested shares of tranche 2 was $20.4 million and was determined on the grant date of August 24, 2022. As of September 30, 2024, the balance of the contract asset related to tranche 2 was $18.8 million. Tranche 3 will vest over the next $1.0 billion of collections from Amazon and its affiliates. The grant date fair value of tranche 3 will also be amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement. As of September 30, 2024, the balance of the contract asset related to tranche 3 was $3.6 million. Because the exercise price has yet to be determined, the fair value of tranche 4 will be remeasured at each reporting period end and amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement.

The assumptions used to calculate the valuations of the 2022 Amazon Warrant as of August 24, 2022 and September 30, 2024 are as follows:

Critical Accounting Estimates

The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an on-going basis, we evaluate our estimates and judgments, including but not limited to those related to revenue recognition, valuation of inventories, intangible assets, valuation of long-lived assets, accrual for service loss contracts, operating and finance leases, allowance for doubtful accounts receivable, unbilled revenue, common stock warrants, stock-based compensation, income taxes, and contingencies. We base our estimates and judgments on historical experience and on various other factors and assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about (1) the carrying values of assets and liabilities and (2) the amount of revenue and expenses realized that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There have been no changes in our critical accounting estimates from those reported in our 2023 Form 10-K.

As previously announced, the Company received a conditional commitment for an up to $1.66 billion loan guarantee from the Department of Energy’s (“DOE”) Loan Programs Office to finance the development, construction, and ownership of up to six green hydrogen production facilities. Our ability to benefit from this loan guarantee is subject to

certain technical, legal, environmental and financial conditions, including negotiation of definitive financing documents, to be satisfied before funding of the loan guarantee. Whether and when our DOE loan guarantee will be funded is subject to a number of factors outside of our control, including political administration changes, legislative enactments, administrative actions. The funding of such loan guarantee may take longer than we expect, and if we are not able to satisfy all of the technical, legal, environmental or financial conditions acceptable to the DOE to receive the loan guarantee, our business may be adversely affected.

We are subject to legal proceedings and legal compliance risks that could harm our business.

We are currently, and in the future may continue to be, subject to legal proceedings and similar disputes. In connection with any disputes or litigation in which we are involved, we may incur costs and expenses in connection with defending ourselves or in connection with the payment of any settlement or judgment or compliance with any ruling in connection therewith. It is often challenging to predict the outcome of legal proceedings and similar disputes with certainty. Determining reserves for any litigation is a complex and fact-intensive process that requires significant judgment calls. There can be no assurance that our expectations will prove correct, and even if these matters are resolved in our favor or without significant cash settlements, these matters, and the time and resources necessary to litigate or resolve them, including diversion of management resources, could have a material adverse effect on our business, results of operations, financial condition and cash flows.
