Plug Power (NASDAQ: PLUG) grows Q1 2026 revenue but posts larger loss
Plug Power Inc. reported first-quarter 2026 results showing higher sales but wider losses. Net revenue reached $163.5M, up from $133.7M a year earlier, driven mainly by electrolyzer, hydrogen infrastructure and fuel sales. Gross loss improved to $21.6M from $73.9M as costs fell.
Net loss attributable to Plug Power widened to $245.3M (basic and diluted loss per share $0.18) from $196.7M (loss per share $0.21). Cash, cash equivalents and restricted cash totaled $802.0M, and working capital was $734.1M. The company continues to post negative operating cash flow but believes existing liquidity, plus at-the-market and standby equity facilities, will fund operations for at least 12 months.

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 $
The Company’s primary sources of liquidity have historically included cash on hand, proceeds from equity and debt financings, and operating cash flows. The Company continues to evaluate opportunities to strengthen its balance sheet and enhance financial flexibility. As part of its ongoing initiatives to strengthen the balance sheet and enhance liquidity, the Company initiated an infrastructure optimization initiative as described in Note 29, “Subsequent Events,” of the notes to the Company’s consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Form 10-K”). If completed as expected, the initiative is reasonably likely to improve the Company’s near-term liquidity position. However, the timing and ultimate magnitude of the impact will depend on execution, satisfaction of closing conditions, market conditions and other factors.
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 $
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 $

2027. During the three months ended March 31, 2026, the Company sold
The Company believes that its working capital, cash position and restricted cash to be released over the next 12 months, and amortization requirements of the Company’s finance obligations, together with other key assumptions, support the Company’s conclusion that it has 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, the Company’s right to direct B. Riley and Yorkville to purchase shares from the Company under the “at-the-market” equity offering program, and the Company’s right to direct Yorkville to purchase shares from the Company under the SEPA.
2. Summary of Significant Accounting Policies
Principles of Consolidation
The unaudited interim condensed consolidated financial statements include the financial statements of the Company and its wholly-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. In addition, we include our share of the results of our joint venture with Acciona Generación Renovable, S.A. in Spain, named AccionaPlug S.L., our investment in Clean H2 Infra Fund and our former joint venture with SK Innovation Co., Ltd, successor in interest to SK E&S Co., Ltd. in South Korea, named SK Plug Hyverse (prior period only), using the equity method based on our economic ownership interest and our ability to exercise significant influence over the operating and financial decisions of AccionaPlug S.L., Clean H2 Infra Fund and SK Plug Hyverse. Additionally, we consolidated the results of Hidrogenii, LLC (“Hidrogenii”), our joint venture with Niloco Hydrogen Holdings LLC, a wholly-owned subsidiary of Olin Corporation (“Olin”).
Interim Financial Statements
The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, which consist solely of normal recurring adjustments, necessary to present fairly, in accordance with U.S. generally accepted accounting principles (“GAAP”), the financial position, results of operations and cash flows for all periods presented, have been made. The results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for the full year.
Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the 2025 Form 10-K.
The information presented in the accompanying unaudited interim condensed consolidated balance sheets as of December 31, 2025 has been derived from the Company’s 2025 audited consolidated financial statements.
Recent Accounting Pronouncements
Recently Adopted Accounting Guidance
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

6. 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.
11
Table of Contents
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. |
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.
The following table summarizes the carrying amount and estimated fair value of the Company’s financial instruments as of March 31, 2026 and December 31, 2025 (in thousands):

15. 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 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, net, gain/(loss) on extinguishment of convertible debt instruments and finance obligations, change in fair value of convertible debt instruments, change in fair value of warrant liabilities, loss on equity method investments, income tax expense and net loss attributable to non-controlling interest, which are presented in the unaudited interim condensed consolidated statements of operations.

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. Except for below, 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
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 complaint, with leave to replead. The plaintiffs filed an amended complaint on February 25, 2025, in which they no longer name Mr. Mindnich. Defendants filed a motion to dismiss the second amended complaint on April 30, 2025. On April 20, 2026, the court issued an opinion and order granting in part and denying in part defendants’ motion to dismiss. Defendants’ responsive pleadings to the complaint are due on May 21, 2026.

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.).

styled Adote v. Plug Power, Inc. et al., No. 1:24-cv-00406-MAD-DJS (N.D.N.Y.) (the "Adote Action"). 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.

Plug Power Inc., et al., No. 1:26-cv-165-MAD-DJS (the "2026 Securities Action"). The complaint alleges that the defendants made misstatements concerning the Company’s business and operations in connection with a loan from the United States Department of Energy’s Loan Program Office for the construction of facilities that would produce and liquefy zero or low-carbon hydrogen. On April 3, 2026, five competing applications were filed by putative class members seeking to be appointed lead plaintiff.
Other Litigation
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.

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.
GenFuel: GenFuel is our liquid hydrogen fueling, delivery, generation, storage, and dispensing system.
28
Table of Contents
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.
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 can produce “green” hydrogen when powered by 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 liquefied hydrogen, oxygen, argon, nitrogen and other cryogenic gases.
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 applications 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.
Liquid Hydrogen: Liquid hydrogen provides an efficient fuel alternative to fossil-based energy. We produce liquid hydrogen at our production facilities in Tennessee, Georgia and Louisiana and through third-party supply arrangements, utilizing electrolyzer systems and liquefaction systems. Liquid hydrogen supply is 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 Europe, Australia, North America and select international markets (including parts of Asia) for expansion in adoption of its hydrogen and electrolyzer solutions.
Currently, we manufacture and/or assemble our products at our manufacturing facilities in Slingerlands, New York; Rochester, New York; Houston, Texas; and Lafayette, Indiana; and have an expanded customer service center in Miamisburg, 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 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 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 “2022 Amazon Warrant”) to acquire up to 16,000,000 shares of the Company’s common stock, subject to certain vesting events, described in Note 10, “Stockholders’ Equity - Share-Based Consideration Payable to a Customer.”
In 2017, the Company issued a warrant to Walmart (the “2017 Walmart Warrant”) to purchase up to 55,286,696 shares of the Company’s common stock, subject to certain vesting events, described in Note 10, “Stockholders’ Equity - Share-Based Consideration Payable to a Customer.” The Company recorded a portion of the estimated fair value of the 2017 Walmart Warrant as a reduction of revenue based upon the projected number of shares of common stock expected to vest under the 2017 Walmart Warrant, the proportion of purchases by Walmart and their affiliates within the period relative to the aggregate purchase levels required for vesting of the 2017 Walmart Warrant, and the then-current fair value of the 2017 Walmart Warrant. On December 30, 2025, the Company entered into an agreement with Walmart in which Walmart agreed to forfeit all vested shares of the Company’s common stock related to the 2017 Walmart Warrant and the unvested portions of the 2017 Walmart Warrant were cancelled. Accordingly, no shares of common stock will become issuable by the Company in connection with the 2017 Walmart Warrant.
The amount of provision for the 2022 Amazon Warrant and 2017 Walmart Warrant recorded as a reduction of revenue during the three months ended March 31, 2026 and 2025, respectively, is shown in the table below (in thousands):

The decrease in cost of revenue was primarily due to improved stack reliability and decreased labor and overhead costs, partially offset by the increase in volume of average number of GenDrive units described above. Gross margin increased to 34.4% for the three months ended March 31, 2026 compared to 14.3% for the three months ended March 31, 2025. The increase in gross margin was primarily due to improved stack reliability and decreased labor and overhead costs.
Cost of revenue – (benefit)/provision for loss contracts related to service. The Company recorded a benefit for loss contracts related to service of ($7.8) million during the three months ended March 31, 2026 compared to a provision for loss contracts related to service of $8.9 million during the three months ended March 31, 2025. The Company recorded a benefit primarily due to improved pricing structure as well as reductions in cost to service our GenDrive units due to improved stack reliability and increased labor utilization.
Cost of revenue – power purchase agreements. Cost of revenue from PPAs includes depreciation of assets utilized and service costs to fulfill PPA obligations and interest costs associated with certain financial institutions for leased equipment. Cost of revenue from PPAs during the three months ended March 31, 2026 decreased $9.8 million, or 19.6%, to $40.1 million from $49.9 million during the three months ended March 31, 2025. The decrease in cost during the three months ended March 31, 2026 was primarily due to improved stack reliability and decreased labor and overhead costs compared to the three months ended March 31, 2025. Gross loss decreased to (52.7%) during the three months ended March 31, 2026 compared to (115.1%) during the three months ended March 31, 2025. The decrease in gross loss was primarily due to improved pricing and the reduction in cost described above.
Cost of revenue – fuel delivered to customers and related equipment. Cost of revenue from fuel delivered to customers and related equipment represents the purchase of hydrogen from suppliers and internally produced hydrogen that is ultimately sold to customers. Cost of revenue from fuel delivered to customers during the three months ended March 31, 2026 decreased $6.5 million, or 10.9%, to $52.9 million from $59.4 million during the three months ended March 31, 2025. The decrease in cost of revenue was primarily due to a decrease in the average cost of purchased fuel during the three months ended March 31, 2026 compared to the three months ended March 31, 2025. Gross loss decreased to (47.8%) during the three months ended March 31, 2026 compared to (101.5%) during the three months ended March 31, 2025. The decrease in gross loss was primarily due to an increase in the average selling price of fuel, decreased cost of purchased fuel and an increase in internal fuel production, which inherently costs less than purchased fuel.

activities. Research and development expense for the three months ended March 31, 2026 decreased $5.3 million, or 30.2%, to $12.1 million from $17.4 million for the three months ended March 31, 2025. The decrease was primarily due to headcount reductions resulting from the Company’s 2025 Restructuring Plan as well as a decrease in research and development project expenses.
Selling, general and administrative. Selling, general and administrative expenses include cash and non-cash stock compensation, benefits, amortization of intangible assets and related costs in support of our general corporate functions, including general management, finance and accounting, human resources, selling and marketing, information technology and legal services. Selling, general and administrative expenses for the three months ended March 31, 2026 decreased $10.6 million, or 13.2%, to $70.2 million from $80.8 million for the three months ended March 31, 2025. The decrease was primarily due to a decrease in contract termination fees, a decrease in professional fees and reductions to the Company’s depreciation and amortization expenses resulting from the Company’s impairment recorded during the fourth quarter of 2025.
Restructuring. Expenses related to restructuring activities for the three months ended March 31, 2026 decreased $15.8 million, or 91.7%, to $1.4 million from $17.2 million for the three months ended March 31, 2025. The decrease was due to lower severance and benefits expenses resulting from restructuring activities during the three months ended March 31, 2026, which impacted less employees than from restructuring activities during the three months ended March 31, 2025.
Impairment. Impairment for the three months ended March 31, 2026 increased $2.8 million, or 262.4%, to $3.9 million from $1.1 million for the three months ended March 31, 2025. The increase was primarily related to the Company recording a higher impairment charge on long-lived assets designated for internal use during the three months ended March 31, 2026.
Change in fair value of contingent consideration. The change in fair value of contingent consideration is related to earn-outs for the Joule Processing LLC (“Joule”) acquisition and Frames Holding B.V. (“Frames”) acquisition (prior period only). The change in fair value of contingent consideration for the three months ended March 31, 2026 and 2025 was $0.3 million and ($11.8) million, respectively.
Interest income. Interest income primarily consists of income generated by our investment holdings, restricted cash escrow accounts, and money market accounts. Interest income for the three months ended March 31, 2026 decreased $1.4 million compared to the three months ended March 31, 2025. The decrease was primarily due to the decrease in the Company’s average restricted cash balance during the first quarter of 2026.
Interest expense. Interest expense consists of interest expense related to our long-term debt, convertible debt instruments, obligations under finance leases and our finance obligations. Interest expense for the three months ended March 31, 2026 increased $5.9 million compared to the three months ended March 31, 2025. The increase was primarily due to interest expense incurred related to the 6.75% Convertible Senior Notes, which was entered into during the fourth quarter of 2025.
Other income, net. Other income, net primarily consists of gains and losses related to energy contracts and foreign currency transactions. Other income, net during the three months ended March 31, 2026 decreased to $1.1 million compared to $1.3 million during the three months ended March 31, 2025.
Gain/(loss) on extinguishment of convertible debt instruments and finance obligations. Gain/(loss) on extinguishment of convertible debt instruments and finance obligations consists of losses that arise from retirement of the Company’s convertible debt instruments and finance obligations before maturity. During the three months ended March 31, 2026 and 2025, the Company recorded a gain/(loss) on extinguishment of convertible debt instruments and finance obligations of $1.8 million and ($3.7) million, respectively. The gain on extinguishment of convertible debt instruments and finance obligations recorded during the three months ended March 31, 2026 was due to a gain on the extinguishment of a finance obligation.

Change in fair value of convertible debt instruments. Change in fair value of convertible debt instruments consists of gains/(losses) that arise from the changes in fair value of the Company’s convertible debt instruments. During the three months ended March 31, 2026, the Company recorded a change in fair value of convertible debt instruments of ($70.8) million compared to a change in fair value of convertible debt instruments of ($7.3) million for the three months ended March 31, 2025. The increase in losses on change in fair value of convertible debt instruments during the three months ended March 31, 2026 was primarily due to an increase in the Company’s common stock price, an increase in the Company’s volatility as well as a larger principal balance of the 6.75% Convertible Senior Notes compared to the principal balance of the Company’s convertible debt instruments held during the three months ended March 31, 2025.
Change in fair value of warrant liabilities. Change in fair value of warrant liabilities consists of gains/(losses) that arise from the changes in fair value of the Company’s $7.75 Warrants. During the three months ended March 31, 2026, the Company recorded a change in fair value of warrant liabilities of ($54.6) million primarily due to an increase in the Company’s common stock price and an increase in the Company’s stock price volatility compared to no change in fair value of warrant liabilities during the three months ended March 31, 2025, as the $7.75 Warrants were issued during the fourth quarter of 2025.
Loss on equity method investments. Loss on equity method investments consists of our interest in AccionaPlug S.L., which is our 50/50 joint venture with Acciona Generación Renovable, S.A. and Clean H2 Infra Fund. Prior to the fourth quarter of 2025, we also held a 49% interest in SK Plug Hyverse, our joint venture with SK Innovation Co., Ltd., successor in interest to SK E&S Co., Ltd. For the three months ended March 31, 2026, the Company recorded a loss of $0.5 million on equity method investments compared to a loss of $2.4 million for the three months ended March 31, 2025. The decrease in loss on equity method investments was primarily due to the Company not recognizing losses related to SK Plug Hyverse during the three months ended March 31, 2026 as the Company sold its entire 49% equity interest in SK Plug Hyverse during the fourth quarter of 2025.
Income Taxes
The Company recorded income tax expense of $41 thousand and $0 during the three months ended March 31, 2026 and 2025, respectively. The income tax expense for the three months ended March 31, 2026 was primarily attributable to current tax incurred in foreign jurisdictions. 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 United States, which remain fully reserved. Except for a few service entities mainly in Europe, all 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. As of March 31, 2026, the Company’s Netherlands subsidiary maintains a full valuation allowance on its deferred tax assets that will not be realized.
Liquidity and Capital Resources
A summary of our consolidated sources and uses of cash, cash equivalents and restricted cash was as follows (in thousands):
| | | | | |
| Three months ended March 31, | ||||
| 2026 | | 2025 | ||
Net cash (used in)/provided by: | | | | | |
Operating activities | $ | (150,041) | | $ | (105,568) |
Investing activities | | (8,481) | | | (46,573) |
Financing activities | | (31,742) | | | 193,232 |
Operating Activities
The net cash used in operating activities during the three months ended March 31, 2026 and 2025 was $150.0 million and $105.6 million, respectively. The increase in net cash used in operating activities was primarily due to an increase in cash used in prepaid expenses and other assets and accounts payable, accrued expenses, and other liabilities as well as an increase in payments of operating lease liabilities, net resulting from strategic buy-outs of the Company’s
34
Table of Contents
operating lease liabilities of $6.9 million during the first quarter of 2026. Those changes were partially offset by a decrease in cash used in inventory and deferred revenue and other contract liabilities as well as an increase in cash provided by accounts receivable.
Investing Activities
The net cash used in investing activities during the three months ended March 31, 2026 and 2025 was $8.5 million and $46.6 million, respectively. The decrease in net cash used in investing activities was primarily due to a decrease in purchases of property, plant and equipment.
Financing Activities
The net cash (used in)/provided by financing activities during the three months ended March 31, 2026 and 2025 was ($31.7) million and $193.2 million, respectively. The decrease from cash provided by financing activities to cash used in financing activities was primarily driven by a decrease in proceeds from public and private offerings as well as an increase in principal repayments of finance obligations and finance leases resulting from strategic buy-outs of the Company’s finance obligations and finance lease liabilities of $8.3 million during the first quarter of 2026. These activities were partially offset by a decrease in principal payments on convertible debt instruments.
Liquidity
The Company has continued to experience negative cash flows from operations and net losses. The Company incurred net losses of approximately $246.0 million and $196.9 million during the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, the Company’s working capital was $734.1 million, which included unrestricted cash and cash equivalents of $223.2 million and current restricted cash of $183.7 million, and the Company had an accumulated deficit of $8.5 billion.
The Company’s primary sources of liquidity have historically included cash on hand, proceeds from equity and debt financings, and operating cash flows. The Company continues to evaluate opportunities to strengthen its balance sheet and enhance financial flexibility. As part of its ongoing initiatives to strengthen the balance sheet and enhance liquidity, the Company initiated an infrastructure optimization initiative as described in Note 29, “Subsequent Events,” of the notes to the Company’s consolidated financial statements in the 2025 Form 10-K. If completed as expected, the initiative is reasonably likely to improve the Company’s near-term liquidity position. However, the timing and ultimate magnitude of the impact will depend on execution, satisfaction of closing conditions, market conditions and other factors.
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. On August 15, 2025, the Company and B. Riley amended the “at-the-market” equity offering program to extend the term. The “at-the-market” equity offering program will terminate upon the earliest of (a) August 15, 2027, with respect to principal and agency transactions, (b) the sale of all shares of common stock under the program or (c) termination of the sales agreement. On September 29, 2025, the Company and B. Riley amended the “at-the-market” equity offering program to add Yorkville Securities, LLC (“Yorkville”) as an additional sales agent and/or principal through which the Company may offer and sell shares pursuant to the “at-the-market” equity offering program. As of March 31, 2026, the Company had $944.1 million of aggregate gross sales price of shares available to be sold under the “at-the-market” equity offering program.
35
Table of Contents
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 months ended March 31, 2026, the Company sold no shares of common stock pursuant to the SEPA.
The Company believes that its working capital, cash position and restricted cash to be released over the next 12 months, and amortization requirements of the Company’s finance obligations, together with other key assumptions, support the Company’s conclusion that it has 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, the Company’s right to direct B. Riley and Yorkville to purchase shares from the Company under the “at-the-market” equity offering program, and the Company’s right to direct Yorkville to purchase shares from the Company under the SEPA.
The Company’s significant obligations consisted of the following as of March 31, 2026:
| (i) | Operating and finance leases totaling $238.5 million and $24.8 million, respectively, of which $63.2 million and $10.1 million, respectively, are due within the next 12 months. These leases are primarily related to sale/leaseback agreements entered into with various financial institutions to facilitate the Company’s commercial transactions with key customers. |
| (ii) | Finance obligations totaling $239.9 million, of which approximately $66.4 million is due within the next 12 months. Finance obligations consist primarily of debt associated with the sale of future revenues and failed sale/leaseback transactions. |
| (iii) | Long-term debt totaling $1.7 million, of which $0.4 million is due within the next twelve months. |
| (iv) | Convertible senior notes totaling $505.3 million, of which $2.5 million is due within the next twelve months. See Note 8, “Convertible Senior Notes,” for more details. |
| (v) | Warrant liabilities totaling $107.0 million, of which none is expected to be due within the next twelve months. See Note 7, “Warrant Liabilities,” for more details. |
| (vi) | Future payments under non-cancellable unconditional purchase obligations with a remaining term in excess of one year totaling $101.5 million, of which $34.5 million is due within the next 12 months. See Note 17, “Commitments and Contingencies,” for more details. |
| (vii) | Contingent consideration with an estimated fair value of approximately $7.8 million, of which $0.6 million is due within the next 12 months. See Note 6, “Fair Value Measurements,” for more details. |
Public and Private Offerings of Equity and Debt
$7.75 Warrants
On March 20, 2025, the Company sold 46,500,000 shares of its common stock, pre-funded warrants to purchase 138,930,464 shares of its common stock and warrants (the “Common Warrants”) to purchase 185,430,464 shares of its common stock in a registered direct offering pursuant to an underwriting agreement with several underwriters.
On October 8, 2025, the Company entered into a warrant exercise inducement agreement with the holder of the Common Warrants, whereby in consideration for exercising the 185,430,464 outstanding Common Warrants at the
36
Table of Contents
exercise price as set forth in the Common Warrants of $2.00 per share, the Company agreed to provide new Common Warrants to the holder to purchase up to 185,430,464 shares of the Company’s common stock at $7.75 per share (the “$7.75 Warrants”). In addition, under the warrant exercise inducement agreement, the holder was permitted to receive, upon exercise, in lieu of 154,430,464 common shares, new pre-funded warrants to purchase 154,430,464 shares of the Company’s common stock at $0.0001 per share.
The $7.75 Warrants contain a provision pursuant to which, upon a Change of Control (as defined in the $7.75 Warrants), the holder may elect to require the Company (or the successor entity) to purchase the warrant for cash equal to its Black-Scholes value (a “Change of Control Cash Election”). The Company has classified the $7.75 Warrants as a liability on the consolidated balance sheets because the Change of Control Cash Election represents a conditional obligation that could require the Company to settle the warrants in cash upon the occurrence of a Change of Control, which precludes equity classification under ASC 815, Derivatives and Hedging (“ASC 815”). The $7.75 Warrants became exercisable on February 28, 2026 and expire on March 20, 2028.
As of March 31, 2026 and December 31, 2025, the $7.75 Warrants were valued at $107.0 million and $52.3 million, respectively, using the following Black-Scholes assumptions:

6.75% Convertible Senior Notes
On November 21, 2025, the Company issued $431.3 million aggregate principal amount of 6.75% convertible senior notes due December 1, 2033 (the “6.75% Convertible Senior Notes”), including the exercise in full of the initial purchasers’ option to purchase up to an additional $56.3 million principal amount of the notes. The notes were issued pursuant to an indenture, dated November 21, 2025 (the “Indenture”).
The notes are convertible at the option of the holders at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock, or a combination of cash and shares of common stock, at the Company’s election, in the manner and subject to the terms and conditions provided in the Indenture; provided that unless and until the reserved share effective date occurs, the Company will settle conversion of notes solely with cash. There were no conversions of the 6.75% Convertible Senior Notes during the three months ended March 31, 2026. As of March 31, 2026, the Company was in compliance with all debt covenants associated with the 6.75% Convertible Senior Notes.

Restricted Cash
In connection with certain of the noted sale/leaseback agreements, cash of $328.0 million and $352.3 million was required to be restricted as security as of March 31, 2026 and December 31, 2025, respectively, which will be released over the lease term. As of March 31, 2026 and December 31, 2025, the Company also had bank guarantees backed by security deposits totaling $170.7 million and $193.1 million, respectively, of which $137.6 million and $159.6 million are security for the noted sale/leaseback agreements, respectively, and $33.1 million and $33.5 million are customs-related letters of credit and bank guarantees, respectively.
As of March 31, 2026 and December 31, 2025, the Company had $62.0 million held in escrow related to the construction of the Texas hydrogen production plant and the Company had $18.1 million and $18.0 million, respectively, held in escrow related to the construction of the Georgia hydrogen production plant.
Guarantee
On February 24, 2026, our joint venture, AccionaPlug S.L., entered into a subsidy agreement with the European Hydrogen Bank, which is managed by Instituto para la Diversificación y Ahorro de la Energía (“IDAE”), a Spanish governing body, to subsidize a renewable hydrogen production project in Spain. In connection with the subsidy agreement, AccionaPlug S.L. is required to meet certain performance targets. The Company has provided a guarantee of €7.5M which can be called by IDAE if the joint venture fails to meet its performance targets under the subsidy agreement. As of March 31, 2026, no payments related to this guarantee have been made by the Company, and the Company did not record a liability for this guarantee as the likelihood of the guarantee being called upon is remote.
Government Tax Credits
Section 48 Investment Tax Credit for Qualified Fuel Cell Properties of Energy Storage Technologies
As of March 31, 2026, the Company determined that it qualified for the Section 48 Investment Tax Credit (“ITC”) for Qualified Fuel Cell Properties of Energy Storage Technologies related to its hydrogen storage and liquefaction assets at its Louisiana hydrogen plant owned by Hidrogenii, the Company’s joint venture with Olin. A base rate credit of 6% is available to qualified energy storage property in the year that it is placed in-service, with availability of increased credit rates if the property qualifies. The Company determined that it qualified for a rate credit of 30%. As the ITC is considered a transferable tax credit, the Company accounts for it as a grant related to assets. Therefore, the ITC was recognized as a reduction to the Louisiana hydrogen production plant’s cost-basis, recognized within property, plant, and equipment, net
38
Table of Contents
in the unaudited interim condensed consolidated balance sheets, which will reduce future depreciation over the next 30 years. As of March 31, 2026, the balance of the ITC was $39.2 million and was recognized in prepaid expenses, tax credits, and other current assets in the unaudited interim condensed consolidated balance sheets.
Unconditional Purchase Obligations
The Company has entered into certain off–balance sheet commitments that require the future purchase of goods or services (“unconditional purchase obligations”). The Company’s unconditional purchase obligations primarily consist of supplier arrangements, take or pay contracts and service agreements. For certain vendors, the Company’s unconditional obligation to purchase a minimum quantity of raw materials at an agreed upon price is fixed and determinable; while certain other raw material costs will vary due to product forecasting and future economic conditions.
Future payments under non-cancellable unconditional purchase obligations with a remaining term in excess of one year as of March 31, 2026 were as follows (in thousands):

During 2025, the Company finalized the renegotiation of a supplier arrangement that previously contained minimum purchase requirements. As of March 31, 2026 and December 31, 2025, the Company had a remaining liability of $19.8 million and $27.2 million, respectively, which was recorded in contingent consideration, loss accrual for service contracts, and other current liabilities. During the three months ended March 31, 2026, the Company made payments of $6.8 million that reduced the liability.
Restructuring
In January 2026, the Company initiated reductions to its workforce (the “2026 Restructuring Plan”). We began executing the 2026 Restructuring Plan in January 2026 and expect the 2026 Restructuring Plan to be substantially completed in the second quarter of 2026, subject to local law and consultation requirements.
In March 2025, the Company announced initiatives to reduce its workforce, realign its manufacturing footprint and streamline its organization to enhance operational efficiency and improve overall liquidity (the “2025 Restructuring Plan”). We began executing the 2025 Restructuring Plan in March 2025 and it was effectively completed during the fourth quarter of 2025.
During the three months ended March 31, 2026 and 2025, the Company incurred $1.4 million and $17.2 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 months ended March 31, 2026 and 2025 (in thousands):

As of March 31, 2026, total accrued expenses related to restructuring activities were comprised of $1.1 million of employee severance and benefit arrangements.
We estimate that we will incur future restructuring costs of $0.2 million related to employee severance and benefit arrangements during the second half of 2026. The actual timing and amount of such costs associated may differ from our current expectations and estimates and such differences may be material.
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 (in thousands):
| | | | | | |

Foreign currency translation adjustment | | | (113) | | | 1,115 |
Ending balance | | $ | 53,189 | | $ | 67,987 |
Product Warranty Reserve
On a quarterly basis, we evaluate our product warranty reserve. The Company applies a failure rate based on product type on total products under warranty identified through a contract-by-contract review to determine its product warranty reserve liability. The Company’s product warranty reserve liability balance as of March 31, 2026 and December 31, 2025 was $22.8 million and $23.0 million, respectively.
Critical Accounting Estimates
The unaudited interim condensed 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, valuation of long-lived assets, valuation of investments, valuation of convertible senior notes and long-term debt, accrual for service loss contracts, operating and finance leases, common stock warrants, stock-based compensation 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.

Recent Accounting Pronouncements
Recently Adopted Accounting Guidance
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 adopted this guidance on January 1, 2026, with no material effect on the Company’s financial position or results of operations.
In November 2024, ASU 2024-04, Debt with Conversion and Other Options (“ASU 2024-04”), was issued to improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20. This standard is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years. The Company adopted this guidance on January 1, 2026, with no material effect on the Company’s financial position or results of operations.
Recent Accounting Guidance Not Yet Effective
Other than the accounting standards mentioned in our 2025 Form 10-K, all issued but not yet effective accounting and reporting standards as of March 31, 2026 are either not applicable to the Company or are not expected to have a material impact on the Company.

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 March 31, 2026. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of March 31, 2026, 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.

Part II. OTHER INFORMATION
Item 1 – Legal Proceedings
See Note 17, “Commitments and Contingencies,” within Part I, Item 1 of this Quarterly Report on Form 10-Q for a discussion regarding material legal proceedings.
Except as otherwise noted, there have been no material developments in legal proceedings. For previously reported information about legal proceedings, refer to Note 25, “Commitments and Contingencies,” of the notes to the Company’s consolidated financial statements in the 2025 Form 10-K.
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 2025 Form 10-K in Part I, Item 1A “Risk Factors.” The risks described in the 2025 Form 10-K 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 2025 Form 10-K, 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 2025 Form 10-K.
Disruptions to international shipping routes and regional instability, including in and around the Strait of Hormuz, may delay deliveries, increase costs, and adversely affect our ability to fulfill customer orders and recognize revenue.
We rely on global logistics, including shipping routes through the Middle East and other key transit networks, to deliver products to our customers. Disruptions affecting these supply chain routes, including geopolitical tensions, military activity, or other instability, may delay, restrict, or prevent the movement of goods, increase transit times, or significantly increase freight, insurance, and security costs. For example, we have experienced and may continue to experience delays in delivering customer orders due to disruptions in and around critical chokepoints such as the Strait of Hormuz. In response, we have utilized, and may continue to utilize, alternative logistics solutions, including overland transportation and rerouting through other ports, which has increased our logistics costs and extended delivery timelines. However, such alternatives may be limited, less reliable, more costly, or unavailable on commercially reasonable terms. They may also introduce additional risks, including damage to products, loss in transit, customs or border delays, and reduced visibility into shipment status.
These types of disruptions may impair our ability to fulfill customer orders in a timely manner, delay commissioning and installation, and defer revenue recognition and cash collections. In addition, we may incur incremental costs such as additional freight, storage, or contractual penalties, and we may be required to provide concessions or other accommodations to customers. Prolonged or severe disruptions could also result in order cancellations, reduced demand, or damage to customer relationships. If we are unable to effectively manage these logistics and transportation risks or adapt our supply chain and delivery methods in a timely and cost-effective manner, our business, financial condition, results of operations, and cash flows could be materially adversely affected.
