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 $862.8 million as of June 30, 2024, which included unrestricted cash and cash equivalents of $62.4 million and restricted cash of $956.5 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 offering 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 (the “Amendment” and, together with the Original ATM Agreement, the “ATM Agreement”) to increase the aggregate offering 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, for a period of 18 months, 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”) and up to $55.0 million of shares in any calendar week (the “Maximum Commitment Advance Purchase Amount Cap”). On and after June 1, 2024, so long as the Company’s market capitalization is no less than $1.0 billion, the Maximum Commitment Advance Purchase Amount will remain $11.0 million and the Maximum Commitment Advance Purchase Amount Cap will remain $55.0 million. If the Company’s market capitalization is less than $1.0 billion on and after June 1, 2024, the Maximum Commitment Advance Purchase Amount will be decreased to $10.0 million and the Maximum Commitment Advance Purchase Amount Cap will be decreased to $30.0 million. Since January 17, 2024, the Company has sold 189,411,442 shares of common stock for gross proceeds of $611.5 million. As of the date of filing of this Quarterly Report on Form 10-Q, the Company has a remaining $690.6 million available under the ATM Agreement.

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 deduction of the underwriting discount and related offering expenses in an underwritten public offering with Morgan Stanley & Co. LLC. The Company granted the underwriter a 30-day option to purchase up to an additional 11,811,023 shares of common stock at the public offering price, less the underwriting discount.

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 ATM Agreement and its public offering of common stock completed in July 2024, 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.

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):


	Six months ended		Year ended
	June 30, 2024		December 31, 2023
Beginning balance	$	137,853	$	81,066
Provision for loss accrual		32,135		85,375
Releases to service cost of sales		(24,937)		(29,713)
Increase to loss accrual related to customer warrants		94		971
Foreign currency translation adjustment		(149)		154
Ending balance	$	144,996	$	137,853

The Company increased its loss accrual to $145.0 million for the six months ended June 30, 2024 primarily due to continued cost increases of GenDrive labor, parts and related overhead coupled with new GenDrive contracts entered into requiring provisions to be set up. As a result, the Company increased its estimated projected costs.

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.

The potentially dilutive securities are summarized as follows:


	As of June 30,
	2024	2023
Stock options outstanding (1)	42,380,705	33,821,392
Restricted stock and restricted stock units outstanding (2)	6,282,815	5,529,831
Common stock warrants (3)	82,022,634	78,561,263

During the second quarter of 2024, the Company began repaying principal and interest on a $2.0 million allowance for tenant work related to its manufacturing facility in Slingerlands, NY. In accordance with ASC 842, Leases (“ASC 842”), the allowance is treated as a freestanding financial instrument separate from the facility lease and is accounted for as long-term debt.

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.

Subject to certain exceptions and subject to certain conditions, holders of the 7.00% Convertible Senior Notes may require the Company to repurchase their 7.00% Convertible Senior Notes upon the occurrence of a “Fundamental Change” (as defined in the Indenture) prior to maturity for cash at a repurchase price equal to 100% of the principal amount of the 7.00% Convertible Senior Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

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.

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. The book value of the 3.75% Notes Capped Call is not remeasured.

customary anti-dilution adjustments. The Common Stock Forward is subject to early settlement or settlement with alternative consideration in the event of certain corporate transactions.

The net cost incurred in connection with the Common Stock Forward of $27.5 million was recorded as an increase in treasury stock in the unaudited interim condensed consolidated balance sheets. The related shares were accounted for as a repurchase of common stock. The book value of the Common Stock Forward is not remeasured.

There were no shares of common stock that settled in connection with the Common Stock Forward during the three and six months ended June 30, 2024 and 2023.

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 June 30, 2024 the balance of the contract asset related to tranche 1 was $19.0 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 June 30, 2024 the balance of the contract asset related to tranche 2 was $19.0 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 June 30, 2024 the balance of the contract asset related to tranche 3 was $1.5 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 June 30, 2024 and December 31, 2023, 2,500,000 and 2,000,000 of the 2022 Amazon Warrant Shares had vested, respectively, and the 2022 Amazon Warrant had not been exercised. During the three and six months ended June 30, 2024 and 2023, there were no exercises with respect to the 2022 Amazon Warrant. 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 June 30, 2024 and 2023 was $1.7 million and $1.5 million, respectively. The total amount of provision for common stock warrants recorded as a reduction of revenue for the 2022 Amazon Warrant during the six months ended June 30, 2024 and 2023 was $2.4 million and $2.6 million, respectively.

Amazon Transaction Agreement in 2017

On April 4, 2017, the Company and Amazon entered into a Transaction Agreement (the “2017 Amazon Transaction Agreement”), pursuant to which the Company agreed to issue to Amazon.com NV Investment Holdings LLC, a warrant (the “2017 Amazon Warrant”) to acquire up to 55,286,696 shares (the “2017 Amazon Warrant Shares”), subject to certain vesting events. The Company and Amazon entered into the 2017 Amazon Transaction Agreement in connection with existing commercial agreements between the Company and Amazon with respect to the deployment of the Company’s GenKey fuel cell technology at Amazon distribution centers. The vesting of the 2017 Amazon Warrant Shares was conditioned upon payments made by Amazon or its affiliates (directly or indirectly through third parties) pursuant to existing commercial agreements. On December 31, 2020, the Company waived the remaining vesting conditions under the 2017 Amazon Warrant, which resulted in the immediate vesting of all of the third tranche of the 2017 Amazon Warrant Shares.

As of June 30, 2024 and 2023, all 55,286,696 of the 2017 Amazon Warrant Shares had vested and the 2017 Amazon Warrant was exercised with respect to 34,917,912 shares of the Company’s common stock. During the three and six months ended June 30, 2024 and 2023, there were no exercises with respect to the 2017 Amazon Warrant. The total amount of provision for common stock warrants recorded as a reduction of revenue for the 2017 Amazon Warrant during the three months ended June 30, 2024 and 2023 was $0.1 million and $0.1 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

Table of Contents

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 June 30, 2024, the balance of the contract asset related to the Walmart Warrant was $5.4 million.

As of June 30, 2024 and December 31, 2023, 37,464,010 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 six months ended June 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 June 30, 2024 was $4.0 million compared to a negative provision for common stock warrants recorded as an addition to revenue of $1.5 million for the three months ended June 30, 2023. The total amount of provision for common stock warrants recorded as a reduction of revenue for the Walmart Warrant during the six months ended June 30, 2024 and 2023 was $7.7 million and $11.5 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

14. Income Taxes

The Company recorded $0.4 million of income tax benefit and $0.9 million of income tax benefit for the three months ended June 30, 2024 and 2023, respectively. The Company recorded $0.2 million of income tax benefit and $2.2 million of income tax benefit for the six months ended June 30, 2024 and 2023, respectively. The income tax benefit for the six months ended June 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

Table of Contents

against its domestic net deferred tax assets, which remain fully reserved, and its valuation allowances recorded in foreign jurisdictions.

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.

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. 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 June 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 six months ended June 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 June 30, 2024
		Carrying		Fair		Fair Value Measurements
		Amount		Value		Level 1		Level 2		Level 3

Table of Contents

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 June 30, 2024 of $90.6 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.

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 $61.4 million and $75.5 million as of June 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. A decrease of $4.1 million was recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the six months ended June 30, 2024, partially offset by an increase of $3.4 million for the three months ended June 30, 2024.

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 $29.2 million and $31.8 million as of June 30, 2024 and December 31, 2023, respectively. The decrease compared to the year ended December 31, 2023 was primarily due to a decrease of $1.6 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the six months ended June 30, 2024, partially offset by an increase of $0.9 million for the three months ended June 30, 2024. A further decrease of $0.3 million and $1.0 million for the three and six months ended June 30, 2024 was due to foreign currency translation gains.

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 fair value of this contingent consideration was $0 and $0.9 million as of June 30, 2024 and December 31, 2023, respectively. The decrease of $0.9 million was due to payments that reduced the fair value of the liability by $1.0 million during the three months ended June 30, 2024. Partially offsetting this decrease was an increase of $0 and $0.1 million recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations during the three and six months ended June 30, 2024, respectively. 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 fair value of this contingent consideration was $0 million and $18.0 million as of June 30, 2024 and December 31, 2023, respectively. The decrease of $18.0 million was due to payments that reduced the fair value of the liability by $18.2 million during the three months ended June 30, 2024. Furthermore, an increase of $0.2 million was recorded in change in fair value of contingent consideration in the unaudited interim condensed consolidated statement of operations for the six months ended June 30, 2024, partially offset by a decrease of $0.5 million for the three months ended June 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 purchase the Company’s shares of common stock and the Company filed a prospectus supplement registering for resale up to 3,461,371 shares of the Company’s common stock issuable upon exercise of the warrants that were issued in connection with such earn-out obligation. The warrants have not been exercised as of June 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 June 30, 2024:


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

17. Operating and Finance Lease Liabilities

As of June 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 Latham, New York and at fueling customer locations.

Litigation

Legal matters are defended and 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. We describe below those legal matters for which a material loss is either (i) possible but not probable, and/or (ii) not reasonably estimable at this time. Liabilities for loss contingencies arising

Table of Contents

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 estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. The Company has not recorded any accruals related to any legal matters.

Securities Litigation and Related Stockholder Derivative Litigation

2021 Securities Action and Related Derivative Litigation

Two actions are pending in which alleged stockholders of the Company assert claims derivatively, on the Company’s behalf, based on allegations and claims that had been asserted in a putative securities class action, In re Plug Power, Inc. Securities Litigation, No. 1:21-cv-2004 (S.D.N.Y. (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 consolidated 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 in which claims have been asserted 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. Based on allegations in the first and second amended complaints 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 has been scheduled on the motion to be held on September 20, 2024.

On May 13, 2021, alleged stockholder Romario St. Clair filed a complaint in the Supreme Court of the State of New York, County of New York, asserting claims derivatively on behalf of the Company against certain current or former directors and officers of the Company. The action is styled St. Clair v. Plug Power Inc. et al., Index No. 653167/2021 (N.Y. Sup. Ct., N.Y. Cty.). By stipulation and order, the action was stayed until motions to dismiss were finally resolved in the 2021 Securities Action. On March 25, 2024, the alleged stockholder plaintiff filed an amended complaint in which claims have been asserted against Mr. Marsh, Mr. Middleton, Mr. McNamee, Mr. Willis, Ms. Helmer, Mr. Kenausis, Mr. Roth, Mr. Schneider, and Mr. Silver, with the Company named as nominal defendant. As had been alleged in the 2021 Securities Action, the amended complaint alleges that the individual defendants knew or consciously disregarded that the Company was experiencing known but undisclosed material weaknesses in its internal controls over financial reporting and had made certain accounting errors later corrected in the Company’s financial restatement in 2021. The complaint further alleges that Mr. Marsh and Mr. Middleton engaged in transactions in the Company’s securities before these issues were disclosed. The plaintiff asserts claims against the individual defendants, derivatively on behalf of the Company, for breach of fiduciary and unjust enrichment. On July 12, 2024, the parties filed a stipulation of discontinuance of the action without prejudice, which the Court approved in an order entered on the same date.

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

Table of Contents

Shrestha, and former officer David Mindnich, on behalf of a putative class of purchasers of Plug Power 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 that “the Company was unable to effectively manage its supply chain and product manufacturing, resulting in reduced revenues and margins, increased inventory levels, and several large deals being delayed until at least 2023, among other issues 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 and on behalf of the Company against certain former and current Company officers and directors based on the claims asserted 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. Schneider, Mr. Silver, Mr. Willis, and current or former directors Jean Bua, Kavita Mahtani, and Kyungyeol Song.

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 Plug 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 allegations in the 2024 Securities Action are substantially similar to those in the consolidated 2023 Securities Action but cover a different putative class period that extends into 2024. 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 Plug Power 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 Plug Power Inc. The complaint alleges misappropriation of trade secrets under both the federal Defend Trade Secrets Act of 2016, 18 U.S.C. § 1836, and the Texas Uniform Trade Secrets Act, three breach of contract claims, and four common law claims under Texas law. On December 5, 2023, the Court granted, in part, the partial motion to dismiss filed by Joule Processing, LLC and Plug Power Inc., and the Court dismissed with prejudice one of the breach of contract claims and the four common law claims. The Court also transferred another of the breach of contract claims to the United States District Court for the Northern District of New York, Case No. 1:23-cv-01528. That claim was dismissed without prejudice, and that matter was closed on April 4, 2024. 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 (the “Amended Application for Injunctive Relief”). Joule Processing, LLC and Plug Power Inc. filed their Response in Opposition to the Amended Application for Injunctive Relief on March 27, 2024, and Jacob Thomas and JTurbo Engineering & Technology, LLC filed their Reply in Support of the Amended Application for Injunctive Relief on April 4, 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.

Plug disagrees with plaintiff’s representations about his time at Plug 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 October 22, 2024.

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.

As of June 30, 2024, one customer comprised approximately 15.2% of the Company’s consolidated accounts receivable balance. At December 31, 2023, one customer comprised approximately 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 June 30, 2024 and 2023, three and two customers accounted for 46.8% and 63.0% of total consolidated revenues, respectively. For the six months ended June 30, 2024 and 2023, two customers accounted for 39.9% and 41.9% of total consolidated revenues, respectively.

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 June 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.

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 second half 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 June 30, 2024, we incurred $1.6 million in restructuring costs recorded as severance expenses of $1.6 million and other restructuring costs of $49 thousand in the restructuring financial statement line item in the unaudited interim condensed consolidated statement of operations. During the six months ended June 30, 2024, we incurred $7.6 million in restructuring costs recorded as severance expenses of $6.8 million and other restructuring costs of $0.8 million in the restructuring financial statement line item in the unaudited interim condensed consolidated statement of operations. We expect to incur another $0.1 million in restructuring costs in subsequent quarters, which are primarily related to severance expenses, and are expected to be incurred during the third quarter of 2024. 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 six months ended June 30, 2024 in accordance with ASC 420 was a result of the separation of full-time employees associated with the Restructuring Plan. As of June 30, 2024, $1.6 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 third quarter of 2024. Other costs are represented by (1) $0.2 million of legal and professional services costs, and (2) $0.6 million of other one-time employee termination benefits. As of June 30, 2024, $28 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 third 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.

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

Table of Contents

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.

Provision for Common Stock Warrants

On August 24, 2022, the Company 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, par value $.01 per share (the “common stock”), subject to certain vesting events described below under “Common Stock Transactions – Amazon Transaction Agreement in 2022”.

In 2017, in separate transactions, the Company issued a warrant to each of Amazon.com NV Investment Holdings LLC and Walmart to purchase up to 55,286,696 shares of the Company’s common stock, subject to certain vesting events described below under “Common Stock Transactions – Amazon Transaction Agreement in 2017” and “Common Stock Transactions – Walmart Transaction Agreement”. The Company recorded a portion of the estimated fair value of the warrants as a reduction of revenue based upon the projected number of shares of common stock expected to vest under the warrants, the proportion of purchases by Amazon, Walmart and their affiliates within the period relative to the aggregate purchase levels required for vesting of the respective warrants, and the then-current fair value of the warrants.

The Company has continued to experience negative cash flows from operations and net losses. The Company incurred net losses of $558.2 million and $443.0 million for the six months ended June 30, 2024 and 2023, respectively, and had an accumulated deficit of $5.0 billion as of June 30, 2024.

A summary of our consolidated sources and uses of cash, cash equivalents and restricted cash was as follows (in thousands):


	Six months ended
	June 30, 2024		June 30, 2023
Net cash (used in) provided by:
Operating activities	$	(422,466)	$	(625,011)
Investing activities		(268,658)		605,487
Financing activities		526,751		25,644
	$	(164,373)	$	6,120

Operating Activities

The net cash used in operating activities for the six months ended June 30, 2024 and 2023 was $422.5 million and $625.0 million, respectively. This decrease in net cash used in operating activities was primarily due to a larger decrease in accounts receivable and a smaller increase in inventory, partially offset by an increase in net loss and an increase in inventory valuation adjustments. The Company’s working capital was $862.8 million as of June 30, 2024, which included unrestricted cash and cash equivalents of $62.4 million.

Investing Activities

The net cash (used in)/provided by investing activities for the six months ended June 30, 2024 and 2023 was ($268.7) million and $605.5 million, respectively. The change from cash inflow to cash outflow from investing activities is primarily due to a decrease in proceeds from maturities of available-for-sale securities during the six months ended June 30, 2024 as the Company no longer holds available-for-sale securities.

Financing Activities

The net cash provided by financing activities for the six months ended June 30, 2024 and 2023 was $526.8 million and $25.6 million, respectively. The increase in cash provided by financing activities was primarily driven by proceeds from the At Market Issuance Sales Agreement during the six months ended June 30, 2024, partially offset by a decrease in proceeds from finance obligations.

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.

There has been no material change from the information provided in the Company’s 2023 Form 10-K under the section titled Item 7A, “Quantitative and Qualitative Disclosures About Market Risk”.

Item 4 — Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports that we file or submit under the Exchange Act, are recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer) as appropriate, to allow for timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of June 30, 2024.

Remediation of Material Weaknesses

In late 2023 and during the first six months of 2024, with the oversight of the Audit Committee of the Board of Directors, the Company executed its remediation plan to address the material weaknesses identified in Item 9A of our annual report on Form 10-K for the year ended December 31, 2023 related to (1) inventory reserves, specifically surrounding the calculation of excess and obsolete inventory and the lower of cost or net realizable value adjustments of inventory, and (2) long-lived asset impairment related to the review and calculation of the carrying value of asset groupings and projections used as a basis for performing our impairment assessments of certain asset groups.

The Company took the following actions during the execution of its remediation plan:

●

Implemented inventory valuation controls at all locations and communicated the requirements for effectively operating such controls to all businesses; and

●

Implemented controls over the review of the calculations associated with the Company’s long-lived asset impairment assessment at a more precise level of operation.

Management has determined, through its current year testing, that these controls have been designed and implemented effectively and that these controls operated effectively for a sufficient period of time to conclude that the previously disclosed material weaknesses related to inventory valuation and long-lived asset impairment identified as of December 31, 2023 have been remediated as of the date of the filing of this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

Item 1A – Risk Factors

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors that could materially affect the Company’s business, financial condition or future results discussed in the Company’s 2023 Form 10-K in Part I, Item 1A “Risk Factors” and the Company’s Form 10-Q for the quarter ended March 31, 2024 in Part II, Item 1A “Risk Factors”. The risks described in the 2023 Form 10-K and the Form 10-Q for the quarter ended March 31, 2024 are not the only risks that could affect the Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect our business, financial condition and/or operating results in the future. As a supplement to the risk factors identified in the 2023 Form 10-K and the Form 10-Q for the quarter ended March 31, 2024, below we have set forth an updated risk factor. Other than as provided below, there have been no material changes to the risk factors identified in the 2023 Form 10-K and the Form 10-Q for the quarter ended March 31, 2024.

The reduction or elimination of government subsidies and economic incentives for alternative energy technologies, or the failure to renew such subsidies and incentives, could reduce demand for our products, lead to a reduction in our revenues, and adversely impact our operating results and liquidity. The Company’s ability to benefit from these subsidies and incentives, in particular the Section 45V Credit for Production of Clean Hydrogen and the Section 48E Clean Electricity Investment Credit, is not guaranteed and is dependent upon the federal government’s forthcoming and ongoing implementation, guidance, regulations, and/or rulemakings that have been the subject of substantial public interest and debate.

We believe that the near term growth of alternative energy technologies will be affected by the availability and size of government and economic incentives. Many of these government incentives expire, phase out over time, may be reduced or discontinued, no longer have available funding, may be implemented differently by changes in administrative agencies, or require renewal by the applicable authority. For example, in August 2022, President Biden signed the IRA into law. The IRA contains hundreds of billions in credits and incentives for the development of renewable energy, clean hydrogen, clean fuels, EVs and supporting infrastructure and carbon capture and sequestration, among other provisions. The IRA contains numerous credits and tax incentives that may be relevant to us, including: (i) a new Section 45V Credit for Production of Clean Hydrogen, which provides a production tax credit of up to $3 per kg of qualified clean hydrogen over a 10-year credit period for the production of qualified clean hydrogen at a qualified facility in the United States; (ii) an extension and amendment of the Section 48 Investment Tax Credit (“ITC”) for Qualified Fuel Cell Properties, including fuel cell technology; (iii) a new Section 48 Investment Tax Credit for Energy Storage Technologies, which expands the applicability of the investment tax credit to include standalone energy storage projects, among other things; and (iv) a new Section 48E Clean Electricity Investment Tax Credit, which provides a tax credit for investment in facilities that generate clean electricity, among other provisions.

There is uncertainty as to how the provisions under the IRA will be interpreted and implemented. The Company’s ability to ultimately benefit from IRA tax credits and incentives, including the aforementioned, is not guaranteed and is dependent upon the implementation, guidance, rulemakings, and/or regulations from the federal government. Several of these credits and tax incentives, in particular the new Section 45V Credit for Production of Clean Hydrogen, have received substantial public interest and have been subject to debate, and divergent views on potential implementation, guidance, rules, and regulatory principles by a diverse group of interested parties - some of whom are advocating for limitations to

Table of Contents

Section 45V that could be materially adverse to the Company and its near term hydrogen generation projects. Specifically, guidance, rules, or regulations limiting a hydrogen production facility’s use of renewable energy credits, environmental attributes, and grid electricity could limit the Company’s ability to benefit from the Section 45V Credit for Production of Clean Hydrogen. As the Company has endeavored numerous hydrogen generation projects prior to the promulgation of Section 45V’s guidance, there is no guarantee that the Company’s projects will comply with the final eligibility requirements of Section 45V. Furthermore, the U.S. Department of Treasury issued a notice of proposed rulemaking on the Section 45V Credit for Production of Clean Hydrogen in December 2023. The notice contained draft regulatory requirements that, if finalized, could have material adverse impacts to the Company’s hydrogen generation projects - both current and planned. In particular, the draft regulation contains numerous provisions unfavorable for the use of grid electricity and renewable energy credits, which are essential to the Company’s ability to claim the Section 45V credit for hydrogen produced at our projects. Relatedly, draft regulations on the Section 48 Investment Tax Credit for Energy Storage Technology contain provisions preventing taxpayers from claiming the energy storage credit for hydrogen storage property not exclusively used for energy-related purposes; and further, draft regulations on the Section 48E Clean Electricity Investment Credit propose burdensome requirements for fuel cells to be eligible for this credit, specifically examination of the greenhouse gas emissions of hydrogen used by the fuel cell system. There is no guarantee that the U.S. Treasury Department’s final regulations will be more advantageous for the Company; and in fact, the final regulatory requirements could become less favorable than the draft regulation in the notice of proposed rulemaking. The effect of the final regulations on our business is not yet known but if we are not able to comply with the final eligibility requirements and our competitors are able to do so, our business may be adversely affected.

Furthermore, future political administration changes, legislative enactments, administrative actions, expiration or changes to clean energy tax credits, policies, or other incentives might be more favorable to other technologies or could limit, amend, repeal, or terminate policies or other incentives that the Company currently hopes to leverage, such as the U.S. Department of Energy Loan Programs Office Loan Guarantee. For example, the Section 48 ITC for qualified fuel cell properties is scheduled to expire for fuel cell properties beginning construction after December 31, 2024, and if not extended, there is no guarantee that Plug’s fuel cell product will qualify for any federal tax credit thereafter. Any reduction, elimination, or discriminatory application of expiration of tax incentives or other government subsidies and economic incentives, or the failure to renew such tax credits, governmental subsidies, or economic incentives, may result in the diminished economic competitiveness of our products to our customers and could materially and adversely affect the growth of alternative energy technologies, including our products, as well as our future operating results and liquidity.
