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; and (b) production of hydrogen. 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 has continued to experience negative cash flows from operations and net losses. The Company incurred net losses of approximately $228.7 million and $262.3 million during the three months ended June 30, 2025 and 2024, respectively. The Company incurred net losses of approximately $425.6 million and $558.1 million during the six months ended June 30, 2025 and 2024, respectively. The Company’s working capital was $494.2 million as of June 30, 2025, which included unrestricted cash and cash equivalents of $140.7 million and current restricted cash of $195.4 million, and the Company had an accumulated deficit of $7.0 billion.
The future use of our available liquidity will be based upon the ongoing review of the funding needs of our businesses, the optimal allocation of our resources, and the timing of cash flow generation. To the extent that we desire to access alternative sources of capital, market conditions could adversely impact our ability to do so at that time and at terms favorable to the Company.
The Company has an “at-the-market” equity offering program 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 under a sales agreement. The “at-the-market” equity offering program will terminate upon the earliest of (a) December 31, 2025 with respect to principal transactions and January 17, 2026 with respect to agency transactions, (b) the sale of all shares of common stock under the program or (c) termination of the sales agreement. During the three months ended June 30, 2025, the Company sold no shares of common stock and during the six months ended June 30, 2025, the Company sold 5,154,177 shares of common stock at a weighted-average sales price of $1.69 per share for gross proceeds of $8.7 million with related issuance costs of $0.2 million through the “at-the-market” equity offering program. As of June 30, 2025, the Company had $986.2 million of aggregate gross sales price of shares available to be sold under the “at-the-market” equity offering program.
The Company has also entered into a Standby Equity Purchase Agreement (the “SEPA”) with Yorkville, pursuant to which the Company has the right, at its option, to sell to Yorkville up to $1.0 billion in the aggregate gross sales price of its common stock, subject to certain limitations and conditions set forth therein. The Company has the right, but not the obligation, from time to time at its sole discretion to direct Yorkville to purchase directly from the Company up to $10.0 million in the aggregate gross sales price of its common stock on any trading day. The SEPA expires on February 10, 2027. During the three and six months ended June 30, 2025, the Company sold no shares of common stock pursuant to the SEPA.
On March 20, 2025, the Company sold 46,500,000 shares of its common stock, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 138,930,464 shares of its common stock and accompanying warrants (the “Common Warrants”) to purchase 185,430,464 shares of its common stock (the “Offering”) in a registered direct offering pursuant to an underwriting agreement with several underwriters. The Company received net proceeds from the Offering of $267.5 million, after deducting the underwriting discount and related expenses and excluding the proceeds, if any, from the exercise of the warrants. The Pre-Funded Warrants became exercisable immediately follow the closing date of the Offering with a term of three years and an exercise price of $0.001 per share of common stock. During the three and six months
ended June 30, 2025, the Pre-Funded Warrants were exercised for 138,930,464 shares of common stock at an exercise price of $0.001 per share. The Common Warrants are exercisable at any time on or after six months after the date of issuance with a term of three years and an exercise price of $2.00 per share of common stock. If all of the Common Warrants in the Offering were to be exercised in cash at their exercise price, the Company would receive additional gross proceeds of approximately $371.0 million.
On May 5, 2025, the Company issued the initial tranche of secured debentures (the “15.00% Secured Debenture”) in the aggregate principal amount of $210.0 million pursuant to the Secured Debenture Purchase Agreement (the “Secured Debenture Purchase Agreement”) with Yorkville for a purchase price of $199.5 million. Under the Secured Debenture Purchase Agreement, Yorkville is committed to purchase a second tranche of secured debentures in an aggregate principal amount of up to $105.0 million for a purchase price of $99.8 million subject to the satisfaction of the closing conditions set forth therein. The Secured Debenture Purchase Agreement also permits the Company to sell to Yorkville a third uncommitted tranche of secured debentures in an aggregate principal amount of up to $210.0 million. All secured debentures issued under the Secured Debenture Purchase Agreement will incur interest at a rate of 15% per annum, which interest will increase to 25% per annum upon the occurrence of an Event of Default (as defined in the Secured Debenture Purchase Agreement) for so long as such event remains uncured and unwaived. The Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the Company’s 6.00% Convertible Debenture. On July 8, 2025, the Company issued to Yorkville a warrant to purchase 31,500,000 shares of common stock (“15.00% Secured Debenture Warrant”). The exercise price of the 15.00% Secured Debenture Warrant was determined at the time of the issuance of the 15.00% Secured Debenture Warrant and equaled $1.37, the lower of (i) the closing price of the Company’s common stock immediately preceding the issuance of the 15.00% Secured Debenture Warrant or (ii) the average closing price of the Company’s common stock for the five trading days immediately preceding the issuance of the 15.00% Secured Debenture Warrant. The 15.00% Secured Debenture Warrant is exercisable at any time on or after the date of issuance and will expire on July 10, 2028.
In addition to the proceeds described above, the Company expects to have savings resulting from the restructuring plan announced in March 2025 (the “2025 Restructuring Plan”). The 2025 Restructuring Plan includes initiatives to reduce our workforce, realign the Company’s manufacturing footprint and streamline the organization to enhance operational efficiency and improve overall liquidity. The expected annual savings from the 2025 Restructuring Plan are expected to be significant and began to be realized in the second half of 2025.
The Company believes that its working capital, cash position and restricted cash to be released over the next 12 months, together with other key assumptions, support the Company’s conclusion that they have sufficient capital 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. Key assumptions are based on factors such as forecasted sales and costs, amortization requirements of the Company’s finance obligations, the Company’s right to direct B. Riley to purchase shares from the Company under the “at-the-market” equity offering program, the Company’s right to direct Yorkville to purchase shares from the Company under the SEPA, the Company’s ability to access sufficient shares within the next twelve months by implementing a reverse stock split, which was approved by its stockholders at the Company’s annual meeting of stockholders on July 3, 2025, and the Company’s ability to access additional debt pursuant to the Secured Debenture Purchase Agreement with Yorkville.

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
In May 2025, Accounting Standards Update 2025-04 (“ASU 2025-04”), Clarifications to Share-Based Consideration Payable to a Customer, was issued to reduce diversity in practice and improve the decision usefulness and operability of the guidance for share-based consideration payable to a customer in conjunction with selling goods or services. This standard is effective for annual periods, including interim reporting periods within annual reporting periods, beginning after December 15, 2026 with early adoption permitted. The Company has not yet adopted ASU 2025-04 and is still evaluating the impact of the adoption on its unaudited interim condensed consolidated financial statements.
In July 2025, Accounting Standards Update 2025-05 (“ASU 2025-05”), Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, was issued to address challenges encountered when applying the guidance in Topic 326 to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. This standard introduces a practical expedient for entities that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This standard is effective for annual periods, including interim reporting periods within annual reporting periods, beginning after December
10
15, 2025 with early adoption permitted. The Company has not yet adopted ASU 2025-05 and is still evaluating the impact of the adoption on its unaudited interim condensed consolidated financial statements.
Other than the accounting standards mentioned above and in our 2024 Form 10-K, all issued but not yet effective accounting and reporting standards as of June 30, 2025 are either not applicable to the Company or are not expected to have a material impact on the Company.
3. 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.
As of June 30, 2025 and 2024, the Company had potentially dilutive shares of common stock totaling 340,788,077 and 175,347,759, respectively.

During the second quarter of 2025, the Company performed an evaluation of one of its equity method investments due to a decline in market conditions and determined that an other-than-temporary impairment exists as of June 30, 2025. The Company determined that its ability and intent to retain the investment for a period of time sufficient to allow for any
12
anticipated recovery in fair value resulted in an other-than-temporary impairment. The estimated fair value was based largely on the future cash flows expected to be generated by the investment using unobservable data points.
As a result, the Company recorded a loss of $42.5 million to the loss on equity method investments financial statement line item in the unaudited interim condensed consolidated statement of operations, which reduced the investments in non-consolidated entities and non-marketable equity securities financial statement line item on the unaudited interim condensed balance sheet as of June 30, 2025.
During the three months ended June 30, 2025, the Company contributed approximately $0.3 million, $0 and $0 to AccionaPlug S.L., SK Plug Hyverse and Clean H2 Infra Fund, respectively. During the three months ended June 30, 2024, the Company contributed approximately $16.1 million, $0, $16.0 million and $9.7 million to HyVia, AccionaPlug S.L., SK Plug Hyverse and Clean H2 Infra Fund, respectively.
During the six months ended June 30, 2025, the Company contributed approximately $0.8 million, $0 and $0 to AccionaPlug S.L., SK Plug Hyverse and Clean H2 Infra Fund, respectively. During the six months ended June 30, 2024, the Company contributed approximately $32.3 million, $1.7 million, $16.0 million and $13.7 million to HyVia, AccionaPlug S.L., SK Plug Hyverse and Clean H2 Infra Fund, respectively.
The Company’s capital commitments related to its equity method investments as of June 30, 2025 was $0.3 million, all of which is expected to be paid during the remainder of 2025.
7. 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:
There were no transfers between Level 1, Level 2, or Level 3 during the six months ended June 30, 2025. 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 AccionaPlug S.L. and Clean H2 Infra Fund. For the one equity method investment that was measured at fair value on a nonrecurring basis, refer to Note 6, “Investments”, for further information.
The following table summarizes the carrying amount and estimated fair value of the Company’s financial instruments as of June 30, 2025 and December 31, 2024 (in thousands):

60,746
The liabilities measured at fair value on a recurring basis that have unobservable inputs and are therefore categorized as Level 3 are related to the 15.00% Secured Debenture, contingent consideration and the 6.00% Convertible Debenture.
The fair value of the 15.00% Secured Debenture as of June 30, 2025 was comprised of a single financial liability in which the Company elected the fair value option under ASC 825, Financial Instruments (“ASC 825”), with changes in fair value recorded in change in fair value of debt in the unaudited interim condensed consolidated statements of operations. There was no change in the instrument-specific credit risk during the three months ended June 30, 2025.
The Company estimated and recorded the fair value of the 15.00% Secured Debenture upon its issuance date of May 5, 2025. The fair value of the 15.00% Secured Debenture as of June 30, 2025 was based on a Probability-Weighted Expected Return Method (“PWERM”). The PWERM includes the Discounted Cash Flow (“DCF”) method corresponding to the relevant amortization schedule in each scenario and a Black-Scholes Option Pricing Model was utilized to estimate the fair value of the 15.00% Secured Debenture Warrant. Additionally, based on the fair value of the 15.00% Secured Debenture and the purchase price of the initial tranche, we estimated the implied yield at the valuation date. The valuation utilized significant Level 3 unobservable inputs, including implied yield, volatility, and risky discount rate. Other significant assumptions include risk-free rate, principal value, the Company’s common stock price and maturity date. Significant judgment is required in selecting the significant inputs and assumptions. Actual assumptions may differ from our current estimates and such differences could materially impact the fair value of the 15.00% Secured Debenture.
Refer to Note 8, “Long Term Debt”, for the change in the carrying amount of the 15.00% Secured Debenture during the three months ended June 30, 2025.
The fair value of contingent consideration as of June 30, 2025 and December 31, 2024 is related to the Joule Processing LLC (“Joule”) acquisition in 2022 and the Frames Holding B.V. (“Frames”) acquisition in 2021.
In the unaudited interim condensed consolidated balance sheets, contingent consideration was recorded in the contingent consideration, loss accrual for service contracts, and other current liabilities and contingent consideration, loss accrual for service contracts, and other liabilities financial statement line items and was comprised of the following unobservable inputs as of June 30, 2025:

In the unaudited interim condensed consolidated balance sheets, contingent consideration was recorded in the contingent consideration, loss accrual for service contracts, and other current liabilities and contingent consideration, loss accrual for service contracts, and other liabilities financial statement line items and was comprised of the following unobservable inputs as of December 31, 2024:
11.83%
15.91% - 16.00%

The fair value of the 6.00% Convertible Debenture as of June 30, 2025 was comprised of a single financial liability in which the Company elected the fair value option under ASC 825, Financial Instruments (“ASC 825”), with changes in fair value recorded in changes in fair value of convertible debenture in the unaudited interim condensed consolidated statements of operations. There was no change in the instrument-specific credit risk during the three and six months ended June 30, 2025.
The fair value of the 6.00% Convertible Debenture as of June 30, 2025 was based on a Monte Carlo simulation of stock price of the Company on a daily basis and a discounted cash flow model that incorporates the amortization schedule, contingent on the daily simulated stock price. The valuation utilized significant Level 3 unobservable inputs, including implied yield, volatility, and risky discount rate. Other significant assumptions include risk-free rate, principal value, the Company’s common stock price, maturity date and the various conversion features and prices per the agreement. Significant judgment is required in selecting the significant inputs and assumptions. Actual assumptions may differ from our current estimates and such differences could materially impact the fair value of the convertible note.
Refer to Note 9, “Convertible Debt Instruments”, for the change in the carrying amount of the 6.00% Convertible Debenture for the three and six months ended June 30, 2025.
8. Long Term Debt
On May 5, 2025, the Company issued the initial tranche of the 15.00% Secured Debenture in the aggregate principal amount of $210.0 million pursuant to the Secured Debenture Purchase Agreement with Yorkville for a purchase price of $199.5 million with a discount of $10.5 million. The 15.00% Secured Debenture was issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The initial tranche of the 15.00% Secured Debenture is subject to an amortization schedule which is scheduled to result in
payment in full on April 30, 2027; however, Yorkville is permitted to defer amortization payments under the Secured Debenture Purchase Agreement, in which case such deferred amortization payments will be paid on the final maturity date of May 1, 2028. Under the Secured Debenture Purchase Agreement, Yorkville is committed to purchase a second tranche of the 15.00% Secured Debenture in an aggregate principal amount of up to $105.0 million for a purchase price of $99.8 million subject to the satisfaction of the closing conditions set forth therein, which expires on May 6, 2026. The Secured Debenture Purchase Agreement also permits the Company to sell to Yorkville a third uncommitted tranche of the 15.00% Secured Debenture in an aggregate principal amount of up to $210.0 million. All secured debentures issued under the Secured Debenture Purchase Agreement will incur interest at a rate of 15% per annum, which interest will increase to 25% per annum upon the occurrence of an Event of Default (as defined in the Secured Debenture Purchase Agreement) for so long as such event remains uncured and unwaived. The Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the 6.00% Convertible Debenture. Refer to Note 9, “Convertible Debt Instruments”, for additional information.
In connection with the closing of the Secured Debenture Purchase Agreement, within five days of the date on which the Company obtains stockholder approval to increase the number of its authorized shares of common stock or to complete a reverse stock split, the Company agreed to issue to Yorkville the 15.00% Secured Debenture Warrant to purchase 31,500,000 shares of common stock.

9. Convertible Debt Instruments
On November 11, 2024, the Company entered into the Debenture Purchase Agreement pursuant to which the Company issued to Yorkville the 6.00% Convertible Debenture in exchange for the payment of $190.0 million. The 6.00% Convertible Debenture was issued in a private placement in reliance upon an exemption from registration provided by Section 4(a)(2) of the Securities Act. The 6.00% Convertible Debenture ranks pari passu in right of payment with all other outstanding and future senior indebtedness of the Company.
In certain circumstances, Yorkville is permitted to convert up to $22.5 million aggregate principal amount of the 6.00% Convertible Debenture plus accrued and unpaid interest thereon, each calendar month beginning with December 2024, at a conversion price equal to the lower of the (1) $2.90 (which was reset to $1.51 in connection with the Offering (the “Fixed Price”)) and (2) 97.25% of the lowest daily volume-weighted average price for the Company’s common stock during the three trading days immediately preceding the applicable conversion date; provided that such Market Price is not less than $0.3941 (the “Floor Price”). During the three months ended June 30, 2025, the Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the 6.00% Convertible Debenture. During the three months ended June 30, 2025, Yorkville converted $82.5 million aggregate principal amount of the 6.00% Convertible Debenture into cash and $20.0 million aggregate principal amount of the 6.00% Convertible Debenture into 28,295,151 shares of the Company’s common stock.

The 15.00% Secured Debenture Warrant was accounted for as permanent equity in accordance with ASC 815, Derivatives and Hedging (“ASC 815”), and was recorded at fair value at inception. The fair value of the warrant was determined using a Black-Scholes Option pricing model, with each scenario weighted based on the probability the warrant will become issuable. The 15.00% Secured Debenture Warrant was recorded to equity at the fair value of $6.1 million on the date of the funding of the initial tranche of the 15.00% Secured Debenture under the Secured Debenture Purchase Agreement.

March 2025 Offering
On March 20, 2025, the Company sold to several underwriters in a registered direct offering 46,500,000 shares of its common stock, Pre-Funded Warrants to purchase 138,930,464 shares of its common stock and accompanying Common Warrants to purchase 185,430,464 shares of its common stock for aggregate gross proceeds of $279.9 million with $11.9 million of underwriting discounts and $0.5 million of related issuance costs.
The Pre-Funded Warrants became exercisable immediately following the closing date of the Offering with a term of three years and an exercise price of $0.001 per share of common stock. During the three and six months ended June 30, 2025, the Pre-Funded Warrants were exercised for 138,930,464 shares of common stock at an exercise price of $0.001 per share for total proceeds of $0.1 million. The Common Warrants are exercisable at any time on or after six months after the date of issuance with a term of three years and an exercise price of $2.00 per share of common stock. If all of the Common Warrants in the Offering were to be exercised in cash at their exercise price, the Company would receive additional gross proceeds of approximately $371.0 million.
Each Common Warrant or Pre-Funded Warrant is exercisable solely by means of a cash exercise, except that a Common Warrant or Pre-Funded Warrant will be exercisable via cashless exercise if at the time of exercise, a registration statement registering the issuance of the shares of common stock underlying the Common Warrants and Pre-Funded Warrants under the Securities Act is not then effective or the prospectus contained therein is not available. The Common Warrants and Pre-Funded Warrants include certain rights upon “fundamental transactions” as described in the Common Warrants and Pre-Funded Warrants, including the right of the holders thereof to receive from the Company or a successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the holders of common stock in such fundamental transaction with respect to the unexercised portion of the applicable Common Warrants or Pre-Funded Warrants immediately prior to such fundamental transaction. Alternatively, the holder of a Common Warrant shall have the right to receive the cash value of the remaining unexercised portion of its Common Warrants upon a fundamental transaction, such value to be calculated using the Black-Scholes Option Pricing Model, as described in the Common Warrants. A holder of the Common Warrants or Pre-Funded Warrants (together with its affiliates) may not exercise any portion of a Common Warrant or Pre-Funded Warrant to the extent that the holder would beneficially own more than 4.99% (or, as may be increased upon written notice at the election of the holder, up to 9.99%) of the Company’s outstanding Common Stock immediately after exercise.
The Pre-Funded Warrants and Common Warrants are freestanding financial instruments that are legally detachable and separately exercisable from the shares of common stock with which they were issued, do not embody an obligation for the Company to repurchase its shares, and permit the holders to receive a fixed number of shares of common stock upon exercise.
As of the issuance date, the common stock was valued at $73.5 million based on the Company’s stock price. The Pre-Funded Warrants and Common Warrants were valued at $219.4 million and $162.5 million, respectively, using the following Black-Scholes assumptions:

Contract balances
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 unaudited interim condensed consolidated balance sheets.
The deferred revenue and other 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 other contract liabilities also include advance consideration received from
22
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 $12 thousand of income tax expense and $0.4 million of income tax benefit during the three months ended June 30, 2025 and 2024, respectively. The Company recorded $12 thousand of income tax expense and $0.2 million of income tax benefit during the six months ended June 30, 2025 and 2024, respectively. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its net deferred tax assets in the U.S., which remain fully reserved. With the exception of a few service entities mainly in Europe, all domestic and foreign deferred tax assets are offset by a full valuation allowance because it is more likely than not that the tax benefits
23
of the net operating loss carryforwards and other deferred tax assets 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.
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law, modifying various federal clean energy tax provisions of the Inflation Reduction Act of 2022 (the “IRA”), including the allowance of immediate expensing of qualifying research and development expenses and permanent extensions of certain provisions within the Tax Cuts and Jobs Act of 2017. The most significant impacts of the OBBBA to the Company are related to Section 45V Credit for Production of Clean Hydrogen, which will be available for clean hydrogen facilities beginning construction before January 1, 2028 and the Section 48E Investment Tax Credit which provides for a 30% investment tax credit for “qualified fuel cell property” from 2026 to 2032. The Company is evaluating the provisions of the OBBBA and its impact on its business.

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 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. 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. In a memorandum opinion and order entered on May 2, 2025, the Court granted all defendants’ motion to dismiss the complaint for failure to make a demand or to adequately alleged demand futility. Plaintiffs initially filed a notice of appeal from that decision, but on June 25, 2025, plaintiffs voluntarily dismissed their appeal.
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. On February 4, 2025, the Court issued an opinion and order dismissing the consolidated
27
complaint, with leave to replead. The plaintiffs filed an amended complaint on February 25, 2025, in which they no longer name Mr. Mindnich, but otherwise substantially release the previous claims. The Company and the other defendants filed a Motion to Dismiss on April 30, 2025 and briefing was completed on July 23, 2025.
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. 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). Appeals from an order appointing lead plaintiffs were denied on July 11, 2025. The Court has directed the lead plaintiffs to file their consolidated amended complaint by August 25, 2025.
Other Litigation
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 discovery deadline was February 28, 2025. Plug Power submitted a motion for summary judgment on April 18, 2025. The parties entered into a settlement agreement that resolves this suit, and the parties filed a stipulation of dismissal with prejudice on June 4, 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.
DOE Loan Guarantee
On January 16, 2025, Plug Power Energy Loan Borrower LLC, a wholly owned indirect subsidiary of the Company, finalized a loan guarantee of up to $1.66 billion with the U.S. Department of Energy (the “DOE”) through the DOE’s Loan Program Office to finance the development, construction, and ownership of up to six green hydrogen production facilities. The Company incurred $15.2 million of closing fees, of which the Company recorded amortization of $0.8 million and $1.4 million during the three and six months ended June 30, 2025, respectively. Of the net $13.8
28
million capitalized closing fees, $2.9 million and $10.9 million are included in prepaid expenses, tax credits, and other current assets and other assets, respectively, on the unaudited interim condensed consolidated balance sheets as of June 30, 2025.
Guarantee
On May 30, 2023, 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 €20.0 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 were certain milestones that HyVia was 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, 2025, no payments related to this guarantee have been made, however the Company recorded a liability of $2.2 million related to this guarantee based on the Company’s estimate of the guarantee being called upon.
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 and take or pay contracts. 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-cancellable unconditional purchase obligations with a remaining term in excess of one year as of June 30, 2025 were as follows (in thousands):
20,692
50,782
64,852
136,326
The Company is renegotiating a supplier arrangement and expects that it will pay a fee in connection with such renegotiation. In connection, the Company has recorded approximately $12.0 million to the selling, general and administrative line in the unaudited interim condensed consolidated statements of operations during the six months ended June 30, 2025.
17. Segment 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 based upon analysis of Plug on a total company basis, including assessments related to our incentive compensation plans. The accounting policies of the segment are the same as those described in the summary of significant accounting policies.
The information regularly provided to the CODM used to assess performance and allocate resources is the same as the Company’s consolidated financial statements. The measure of segment profit or loss used by the CODM in assessing
segment performance and how to allocate resources is consolidated net loss which is presented in the unaudited interim condensed consolidated statements of operations. The CODM uses net loss in strategic planning, for example, decision making of whether to allocate resources towards strengthening sales channels, investing in research and development, focusing on cost-down initiatives, and/or analyzing Company overhead in respect to specific products and service lines. Net loss is also used to monitor budget versus actual results and is considered in assessments related to company-wide incentive compensation. The significant segment expenses included within the segment measure of profit or loss are total costs of revenue, research and development expense, selling, general and administrative expense, and impairment expense. Other segment items are comprised of restructuring, change in fair value of contingent consideration, interest income, interest expense, other income/(expense), net, loss on extinguishment of convertible debt instruments and debt, change in fair value of convertible debenture, change in fair value of debt, loss on equity method investments, income tax (expense)/benefit and net loss attributable to non-controlling interest, which are presented in the unaudited interim condensed consolidated statements of operations. The CODM is not regularly provided a measure of segment assets.

19. Restructuring
In March 2025, the Company announced the 2025 Restructuring Plan, which included initiatives to reduce our workforce, realign the Company’s manufacturing footprint and streamline the organization to enhance operational efficiency and improve overall liquidity. We began executing the 2025 Restructuring Plan in March 2025 and expect the 2025 Restructuring Plan to be completed in the second half of 2025, subject to local law and consultation requirements.
In February 2024, the Company announced a restructuring plan (the “2024 Restructuring Plan”). The 2024 Restructuring Plan included strategic moves to enhance our financial performance and ensure long-term value creation in a competitive market. We began executing the 2024 Restructuring Plan in February 2024 and it was effectively completed during the fourth quarter of 2024.
During the three months ended June 30, 2025 and 2024, the Company incurred $2.9 million and $1.6 million in restructuring costs, respectively, which were recorded in the restructuring financial statement line item in the unaudited interim condensed consolidated statements of operations. During the six months ended June 30, 2025 and 2024, the Company incurred $20.1 million and $7.6 million in restructuring costs, respectively, which were recorded in the restructuring financial statement line item in the unaudited interim condensed consolidated statements of operations. The following table reflects the category of restructuring charges incurred during the three and six months ended June 30, 2025 and 2024 (in thousands):

As of June 30, 2025, total accrued expenses related to restructuring activities were comprised of (1) $4.5 million of employee severance and benefit arrangements and (2) $0.2 million of legal and professional services costs.
We estimate that we will incur future restructuring costs of $0.4 million related to employee severance and benefit arrangements. In addition, we expect to incur future restructuring costs related to facility exit costs during 2025; however, the Company cannot estimate the total amount expected to be incurred as cost reduction actions continue to be evaluated. The Company anticipates completing these restructuring activities in the second half of 2025. 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.

20. Variable Interest Entities
Hidrogenii
In the third quarter of 2022, our wholly-owned subsidiary, Plug Power LA JV, LLC, created a joint venture with Niloco Hydrogen Holdings LLC, a wholly-owned subsidiary of Olin, named Hidrogenii to support reliability of supply and speed to market for hydrogen throughout North America and set the foundation for broader collaboration between Plug and Olin. During the second quarter of 2025, Hidrogenii placed into service a 15-ton-per-day hydrogen plant in St. Gabriel, Louisiana. Hidrogenii is owned 50% by Plug Power LA JV, LLC and 50% by Niloco Hydrogen Holdings LLC.
The Company has determined Hidrogenii to be a VIE, and the Company is considered to be the VIE’s primary beneficiary, as we determined we have both the power to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. On an ongoing basis, we are contractually obligated to certain operational funding. We consolidated the joint venture’s results within our single consolidated reportable segment. Hidrogenii has similar risks to those described in Item 1A, “Risk Factors”, in the Company’s 2024 Form 10-K.
The VIE’s assets can be used to settle only the VIE’s obligations and the creditors related to the VIE’s liabilities have no recourse against the general credit of the Company. The table below summarizes balances associated with Hidrogenii as reflected on our unaudited interim condensed consolidated balance sheets as of June 30, 2025 and December 31, 2024 (in thousands):

21. Subsequent Events
On July 8, 2025, the Company issued the 15.00% Secured Debenture Warrant to Yorkville. The exercise price of the 15.00% Secured Debenture Warrant was determined at the time of the issuance of the 15.00% Secured Debenture Warrant and equaled $1.37, the lower of (i) the closing price of the Company’s common stock immediately preceding the issuance of the 15.00% Secured Debenture Warrant or (ii) the average closing price of the Company’s common stock for the five trading days immediately preceding the issuance of the 15.00% Secured Debenture Warrant. The 15.00% Secured Debenture Warrant is exercisable at any time on or after the date of issuance and will expire on July 10, 2028.
32
Subsequent to issuance on July 8, 2025, the 15.00% Secured Debenture Warrant was partially exercised for 6,500,000 shares of the Company’s common stock for gross proceeds of $8.9 million.

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with our accompanying unaudited interim condensed consolidated financial statements and notes thereto included within this Quarterly Report on Form 10-Q, and our audited consolidated financial statements and notes thereto included in our 2024 Form 10-K. In addition to historical information, this Quarterly Report on Form 10-Q and the following discussion contain statements that are not historical facts and are considered forward-looking within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. These forward-looking statements contain projections of our future results of operations or of our financial position or state other forward-looking information. In some cases, you can identify these statements by forward-looking words such as “anticipate,” “believe,” “could,” “continue,” “estimate,” “expect,” “forecast,” “intend,” “may,” “should,” “will,” “would,” “plan,” “potential,” “project” or the negative of such words or other similar words or phrases. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to accurately predict or control and that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Investors are cautioned not to unduly rely on forward-looking statements because they involve risks and uncertainties, and actual results may differ materially from those discussed as a result of various factors, including, but not limited to:
The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks discussed in the section titled “Risk Factors” included under Part I, Item 1A, in our 2024 Form 10-K and supplemented by Part II, Item 1A of the Quarterly Report on Form 10-Q for the quarter ended March 31, 2025. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for management to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from these contained in any forward-looking statements. While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. These forward-looking statements speak only as of the date on which the statements were made. Except as may be required by applicable law, we do not undertake or intend to update any forward-looking statements after the date of this Quarterly Report on Form 10-Q.
References in this Quarterly Report on Form 10-Q to “Plug”, the “Company”, “we”, “our” or “us” refer to Plug Power Inc., including as the context requires, its subsidiaries.

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; and (b) production of hydrogen. 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 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 applications on both a small and large power scale. For smaller applications, Plug’s Low Power GenSure supports backup and grid-support application of the telecommunications, transportation, and utility sectors. Our High Power GenSure product line supports large scale stationary power, EV charging infrastructure, and data center markets.
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 and GenFuel hydrogen storage and dispensing products.
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.
GenEco 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.
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.
36
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.
Currently, we manufacture and/or assemble our products at our manufacturing facilities in Rochester, New York; Slingerlands, New York; Houston, Texas; and Lafayette, Indiana; and have an expanded customer service center in Dayton, Ohio. In addition, we have hydrogen production plants in Charleston, Tennessee; Kingsland, Georgia; and St. Gabriel, Louisiana.
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 delivery and 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 plants.
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 (“Amazon”), a warrant (the “Amazon Warrant”) to acquire up to 16,000,000 shares of the Company’s 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 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 amount of provision for the Amazon and Walmart warrants recorded as a reduction of revenue during the three and six months ended June 30, 2025 and 2024, respectively, is shown in the table below (in thousands):

The increase in loss on equity method investments was primarily due to the Company recording an other-than-temporary impairment loss of $42.5 million related to the Company’s investment in one of its equity method investments due to a decline in market conditions.
For the six months ended June 30, 2025, the Company recorded a loss of $48.2 million on equity method investments compared to a loss of $20.4 million for the six months ended June 30, 2024. The increase in loss on equity method investments was primarily due to the Company recording an other-than-temporary impairment loss of $42.5 million related to the Company’s investment in one of its equity method investments due to a decline in market conditions. The increase in loss on equity method investments was partially offset by the Company recording no losses related to HyVia during the six months ended June 30, 2025 as the joint venture entered into receivership proceedings during the fourth quarter of 2024.
Income Taxes
The Company recorded $12 thousand of income tax expense and $0.4 million of income tax benefit during the three months ended June 30, 2025 and 2024, respectively. The Company recorded $12 thousand of income tax expense and $0.2 million of income tax benefit during the six months ended June 30, 2025 and 2024, respectively. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its net deferred tax assets in the U.S., which remain fully reserved. With the exception of a few service entities mainly in Europe, all domestic and foreign deferred tax assets are offset by a full valuation allowance because it is more likely than not that the tax benefits of the net operating loss carryforwards and other deferred tax assets 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.
A summary of our consolidated sources and uses of cash, cash equivalents and restricted cash was as follows (in thousands):
Net cash (used in)/provided by:
Operating Activities
The net cash used in operating activities during the six months ended June 30, 2025 and 2024 was $297.4 million and $422.5 million, respectively. The decrease in net cash used in operating activities was primarily due to the decrease in net loss during the six months ended June 30, 2025 compared to the six months ended June 30, 2024. Other changes to net cash used in operating activities include an increase in cash provided by inventory and prepaid expenses and other assets. Those changes were partially offset by a decrease in cash provided by accounts receivable, a decrease in non-cash inventory valuation adjustments and a recovery on service contracts during the six months ended June 30, 2025 compared to a loss on service contracts during the six months ended June 30, 2024.
Investing Activities
The net cash used in investing activities during the six months ended June 30, 2025 and 2024 was $87.3 million and $268.7 million, respectively. The decrease in net cash used in investing activities was primarily due to a decrease in purchases of property, plant and equipment as well as a decrease in contributions to equity method investments during the six months ended June 30, 2025.
Financing Activities
The net cash provided by financing activities during the six months ended June 30, 2025 and 2024 was $226.1 million and $526.8 million, respectively. The decrease in cash provided by financing activities was primarily driven by a
45
decrease in proceeds from public and private offerings and an increase in principal payments on convertible debentures, partially offset by an increase in proceeds from debt issuance.
The Company has also entered into a Standby Equity Purchase Agreement (the “SEPA”) with Yorkville, pursuant to which the Company has the right, at its option, to sell to Yorkville up to $1.0 billion in the aggregate gross sales price of its common stock, subject to certain limitations and conditions set forth therein. The Company has the right, but not the obligation, from time to time at its sole discretion to direct Yorkville to purchase directly from the Company up to $10.0 million in the aggregate gross price sales of its common stock on any trading day. The SEPA expires on February 10, 2027. During the three and six months ended June 30, 2025, the Company sold no shares of common stock pursuant to the SEPA.
On March 20, 2025, the Company sold 46,500,000 shares of its common stock, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 138,930,464 shares of its common stock and accompanying warrants (the “Common Warrants”) to purchase 185,430,464 shares of its common stock (the “Offering”) in a registered direct offering pursuant to an underwriting agreement with several underwriters. The Company received net proceeds from the Offering of $267.5 million, after deducting the underwriting discount and related expenses and excluding the proceeds, if any, from the exercise of the warrants. The Pre-Funded Warrants became exercisable immediately follow the closing date of the Offering with a term of three years and an exercise price of $0.001 per share of common stock. During the three and six months ended June 30, 2025, the Pre-Funded Warrants were exercised for 138,930,464 shares of common stock at an exercise price of $0.001 per share. The Common Warrants are exercisable at any time on or after six months after the date of issuance with a term of three years and an exercise price of $2.00 per share of common stock. If all of the Common Warrants in the Offering were to be exercised in cash at their exercise price, the Company would receive additional gross proceeds of approximately $371.0 million.
On May 5, 2025, the Company issued the initial tranche of secured debentures (the “15.00% Secured Debenture”) in the aggregate principal amount of $210.0 million pursuant to the Secured Debenture Purchase Agreement (the “Secured Debenture Purchase Agreement”) with Yorkville for a purchase price of $199.5 million. Under the Secured Debenture Purchase Agreement, Yorkville is committed to purchase a second tranche of secured debentures in an aggregate principal amount of up to $105.0 million for a purchase price of $99.8 million subject to the satisfaction of the closing conditions set forth therein. The Secured Debenture Purchase Agreement also permits the Company to sell to Yorkville a third
46
uncommitted tranche of secured debentures in an aggregate principal amount of up to $210.0 million. All secured debentures issued under the Secured Debenture Purchase Agreement will incur interest at a rate of 15% per annum, which interest will increase to 25% per annum upon the occurrence of an Event of Default (as defined in the Secured Debenture Purchase Agreement) for so long as such event remains uncured and unwaived. The Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the Company’s 6.00% Convertible Debenture. On July 8, 2025, the Company issued to Yorkville a warrant to purchase 31,500,000 shares of common stock (“15.00% Secured Debenture Warrant”). The exercise price of the 15.00% Secured Debenture Warrant was determined at the time of the issuance of the 15.00% Secured Debenture Warrant and equaled $1.37, the lower of (i) the closing price of the Company’s common stock immediately preceding the issuance of the 15.00% Secured Debenture Warrant or (ii) the average closing price of the Company’s common stock for the five trading days immediately preceding the issuance of the 15.00% Secured Debenture Warrant. The 15.00% Secured Debenture Warrant is exercisable at any time on or after the date of issuance and will expire on July 10, 2028.
The Company’s significant obligations consisted of the following as of June 30, 2025:
47
Public and Private Offerings of Equity and Debt
Each Common Warrant or Pre-Funded Warrant is exercisable solely by means of a cash exercise, except that a Common Warrant or Pre-Funded Warrant will be exercisable via cashless exercise if at the time of exercise, a registration statement registering the issuance of the shares of common stock underlying the Common Warrants and Pre-Funded Warrants under the Securities Act is not then effective or the prospectus contained therein is not available. The Common Warrants and Pre-Funded Warrants include certain rights upon “fundamental transactions” as described in the Common
48
Warrants and Pre-Funded Warrants, including the right of the holders thereof to receive from the Company or a successor entity the same type or form of consideration (and in the same proportion) that is being offered and paid to the holders of common stock in such fundamental transaction with respect to the unexercised portion of the applicable Common Warrants or Pre-Funded Warrants immediately prior to such fundamental transaction. Alternatively, the holder of a Common Warrant shall have the right to receive the cash value of the remaining unexercised portion of its Common Warrants upon a fundamental transaction, such value to be calculated using the Black-Scholes Option Pricing Model, as described in the Common Warrants. A holder of the Common Warrants or Pre-Funded Warrants (together with its affiliates) may not exercise any portion of a Common Warrant or Pre-Funded Warrant to the extent that the holder would beneficially own more than 4.99% (or, as may be increased upon written notice at the election of the holder, up to 9.99%) of the Company’s outstanding Common Stock immediately after exercise.
As of the issuance date, the common stock was valued at $73.5 million based on the Company’s stock price.
The Pre-Funded Warrants and Common Warrants were valued at $219.4 million and $162.5 million, respectively, using the following Black-Scholes assumptions:
“At-the-Market” Equity Offering Program
On May 5, 2025, the Company issued the initial tranche of the 15.00% Secured Debenture in the aggregate principal amount of $210.0 million pursuant to the Secured Debenture Purchase Agreement with Yorkville for a purchase price of $199.5 million with a discount of $10.5 million. The 15.00% Secured Debenture was issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The initial tranche of the 15.00% Secured Debenture is subject to an amortization schedule which is scheduled to result in payment in full on April 30, 2027; however, Yorkville is permitted to defer amortization payments under the Secured Debenture Purchase Agreement, in which case such deferred amortization payments will be paid on the final maturity date of May 1, 2028. Under the Secured Debenture Purchase Agreement, Yorkville is committed to purchase a second tranche of the 15.00% Secured Debenture in an aggregate principal amount of up to $105.0 million for a purchase price of $99.8
million subject to the satisfaction of the closing conditions set forth therein, which expires on May 6, 2026. The Secured Debenture Purchase Agreement also permits the Company to sell to Yorkville a third uncommitted tranche of the 15.00% Secured Debenture in an aggregate principal amount of up to $210.0 million. All secured debentures issued under the Secured Debenture Purchase Agreement will incur interest at a rate of 15% per annum, which interest will increase to 25% per annum upon the occurrence of an Event of Default (as defined in the Secured Debenture Purchase Agreement) for so long as such event remains uncured and unwaived. The Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the 6.00% Convertible Debenture. Refer to Note 9, “Convertible Debt Instruments”, for additional information.
50
In certain circumstances, Yorkville is permitted to convert up to $22.5 million aggregate principal amount of the 6.00% Convertible Debenture plus accrued and unpaid interest thereon, each calendar month beginning with December 2024, at a conversion price equal to the lower of (1) $2.90 (which was reset to $1.51 in connection with the Offering (the “Fixed Price”)) and (2) 97.25% of the lowest daily volume-weighted average price for the Company’s common stock during the three trading days immediately preceding the applicable conversion date; provided that such Market Price is not less than $0.3941 (the “Floor Price”). During the three months ended June 30, 2025, the Company used a portion of the net proceeds from the initial tranche of the 15.00% Secured Debenture to retire $60.0 million of principal on the 6.00% Convertible Debenture. During the three months ended June 30, 2025, Yorkville converted $82.5 million aggregate principal amount of the 6.00% Convertible Debenture into cash and $20.0 million aggregate principal amount of the 6.00% Convertible Debenture into 28,295,151 shares of the Company’s common stock. During the six months ended June 30, 2025, Yorkville converted $127.5 million aggregate principal amount of the 6.00% Convertible Debenture into cash and $50.0 million aggregate principal amount of the 6.00% Convertible Debenture into 38,736,057 shares of the Company’s common stock. The 6.00% Convertible Debenture was fully settled as of June 30, 2025.

On January 16, 2025, Plug Power Energy Loan Borrower LLC, a wholly owned indirect subsidiary of the Company, finalized a loan guarantee of up to $1.66 billion with the U.S. Department of Energy (the “DOE”) through the DOE’s Loan Program Office to finance the development, construction, and ownership of up to six green hydrogen production facilities.

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 and intangible assets, valuation of long-lived assets, valuation of equity method investments, accrual for service loss contracts, operating and finance leases, allowance for credit losses, 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
56
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 2024 Form 10-K.
Recently Issued and Not Yet Adopted Accounting Pronouncements
In July 2025, Accounting Standards Update 2025-05 (“ASU 2025-05”), Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, was issued to address challenges encountered when applying the guidance in Topic 326 to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. This standard introduces a practical expedient for entities that assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. This standard is effective for annual periods, including interim reporting periods within annual reporting periods, beginning after December 15, 2025 with early adoption permitted. The Company has not yet adopted ASU 2025-05 and is still evaluating the impact of the adoption on its unaudited interim condensed consolidated financial statements.
Item 3 — Quantitative and Qualitative Disclosures about Market Risk
There has been no material change from the information provided in the Company’s 2024 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 is 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, 2025. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer
have concluded that as of June 30, 2025, our disclosure controls and procedures were effective. We continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.
Changes in Internal Control over Financial Reporting
There were no changes to the internal control over financial reporting of the Company identified in connection with the Company’s evaluation referred to above that occurred during the quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds
The Warrant was issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). The shares of common stock that may be issued upon exercise of the Warrant will be issued pursuant to the same exemption or pursuant to the exemption provided by Section 3(a)(9) of the Securities Act.
On July 9, 2025, the Company filed a prospectus supplement to its automatic shelf registration statement on Form S-3 (File No. 333-287577) relating to the resale by YA II PN, Ltd. of the common stock issuable upon exercise of the Warrant. If the Warrant is exercised on a cash basis for all 31,500,000 shares of common stock, the Company will receive proceeds of approximately $43.2 million. The Company expects to use any such proceeds primarily for working capital and general corporate purposes. In the event that at the time of exercise of the Warrant, there is no effective registration statement, or the prospectus contained therein is not available for the issuance or resale of the shares of common stock, YA II PN, Ltd. may exercise the Warrant on a “cashless basis” which, if elected by YA II PN, Ltd., will reduce the number of shares of common stock issued upon exercise of the Warrant in lieu of cash payment.
