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 to replace lead-acid and lithium batteries in electric material handling vehicles and industrial trucks for some of the world’s largest retail-distribution and manufacturing businesses, we have expanded our offerings to support a variety of commercial operations that can be powered with green hydrogen. We also provide electrolyzers that allow customers — such as refineries, producers of chemicals, steel and fertilizer and commercial refueling stations — to generate hydrogen on-site. Additionally, we intend for our electrolyzers to be used to generate green hydrogen within Plug’s own plants that will then be sold to customers. We are focusing our efforts on 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. Additionally, we manufacture and sell fuel cell products to replace batteries and diesel generators in stationary back-up power applications for telecommunications, transportation, and utility customers. Plug supports these markets with an ecosystem of integrated products that make, transport, handle, dispense and use hydrogen.

Of the total earnout consideration, $90 million is related to the achievement of certain financial performance and $40 million is related to the achievement of certain internal operational milestones.

The following table summarizes the preliminary allocation of the purchase price to the estimated fair value of the net assets acquired, excluding goodwill (in thousands):


Current assets	$	2,672
Property, plant and equipment		493
Right of use asset		182
Identifiable intangible assets		60,522
Lease liability		(374)
Current liabilities		(2,612)
Contract liability		(3,818)
Total net assets acquired, excluding goodwill	$	57,065

The preliminary allocation of the purchase price is still considered provisional due to the finalization of the valuation for the assets acquired and liabilities assumed in relation to the Joule acquisition. Therefore, the fair values of the assets acquired and liabilities assumed are subject to change as we obtain additional information for valuation assumptions such as market demand for Joule product lines to support forecasted revenue growth and the likelihood of achieving earnout milestones during the measurement period, which will not exceed 12 months from the date of acquisition. During the three months ended June 30, 2022, the Company recorded an adjustment to goodwill of $136 thousand due to the payment of a hold back liability related to the Joule acquisition and was recorded in accrued expenses in the unaudited interim condensed consolidated balance sheet.

The fair value of the developed technology totaling $59.2 million included in the identifiable intangible assets was calculated using the multi-period excess earnings method (“MPEEM”) approach which is a variant of the income approach. The basic principle of the MPEEM approach is that a single asset, in isolation, is not capable of generating cash flow for an enterprise. Several assets are brought together and exploited to generate cash flow. Therefore, to determine cash flow from the developed technology over its useful life of 15 years, one must deduct the related expenses incurred for the exploitation of other assets used for the generation of overall cash flow. The fair value of the tradename totaling $0.8 million was calculated using the relief from royalty approach which is a variant of the income approach, and was assigned a useful life of four years. The fair value of the non-compete agreements was $0.5 million with a useful life of six years.

In addition to identifiable intangible assets, the fair value of acquired work in process and finished goods inventory, included in inventory, was estimated based on the estimated selling price less costs to be incurred and a market participant profit rate.

In connection with the acquisition, the Company recorded on its consolidated balance sheet a liability of $41.7 million representing the fair value of contingent consideration payable, and is recorded in the unaudited interim condensed consolidated balance sheet in the loss accrual for service contracts and other liabilities. The fair value of this contingent consideration was remeasured to $36.9 million as of June 30, 2022, and as a result a $4.8 million reduction was recorded in the unaudited interim condensed consolidated statement of operations for the three and six months ended June 30, 2022.

Included in the purchase price consideration are contingent earn-out payments as described above. Due to the nature of the earn-outs, a scenario based analysis using the probability of achieving the milestone expectations was used to determine the fair value of the contingent consideration. These fair value measurements were based on unobservable inputs and are considered to be level 3 financial instruments.

The goodwill was primarily attributed to the value of synergies created with the Company’s current and future offerings and the value of the assembled workforce. Goodwill and intangible assets are not deductible for income tax purposes. Goodwill associated with the Joule acquisition was calculated as follows (in thousands):


Consideration paid	$	28,140
Contingent consideration		41,732
Less: net assets acquired		(57,065)
Total goodwill recognized	$	12,807

The acquisition of Joule contributed $2.0 million and $3.3 million to total consolidated revenue for the three and six months ended June 30, 2022, respectively. The Company determined it impractical to report net loss for the Joule acquisition for the three and six months ended June 30, 2022.

Applied Cryo Technologies Acquisition

On November 22, 2021, the Company acquired 100% of the outstanding shares of Applied Cryo Technologies, Inc. (“Applied Cryo”). Applied Cryo is a manufacturer of engineered equipment servicing multiple applications, including cryogenic trailers and mobile storage equipment for the oil and gas markets and equipment for the distribution of liquified hydrogen, oxygen, argon, nitrogen, and other cryogenic gases.

The fair value of consideration paid by the Company in connection with the Applied Cryo acquisition was as follows (in thousands):


Cash	$	98,559
Plug Power Inc. Common Stock		46,697
Contingent consideration		14,000
Settlement of preexisting relationship		2,837
Total consideration	$	162,093

Included in the $98.6 million of cash consideration above, $5.0 million is consideration held by our paying agent in connection with the acquisition and is reported as restricted cash, with a corresponding accrued liability as of June 30, 2022 on the Company’s unaudited interim condensed consolidated balance sheet. We expect that this will be settled in the second half of 2022.

The contingent consideration represents the estimated fair value associated with earn-out payments of up to $30.0 million that the sellers are eligible to receive in cash or shares of the Company’s common stock (at the Company’s election). Of the total earnout consideration, $15.0 million is related to financial performance, and $15.0 million is related to internal operational milestones.

The following table summarizes the preliminary allocation of the purchase price to the estimated fair value of the net assets acquired, excluding goodwill (in thousands):

Deferred tax liability		(16,541)
Deferred revenue		(12,990)
Total net assets acquired, excluding goodwill	$	69,365

The preliminary allocation of the purchase price is still considered provisional due to the tradename, technology, and customer relationship valuations. The Company continues to evaluate valuation assumptions such as the market demand for the Applied Cryo existing product lines to support forecasted revenue growth. Additionally, the Company continues to research the technology and buying power of Applied Cryo and evaluate the likelihood of achieving the additional production capacity needed in a timely manner to meet earnout milestones. During the three months ended June 30, 2022, the Company recorded a measurement period adjustment to goodwill of $0.5 million due to a release of escrow, which was recorded to accrued expenses in the unaudited interim condensed consolidated balance sheet. Any necessary adjustments will be finalized within one year from the date of acquisition.

Identifiable intangible assets consisted of developed technology, tradename, acquired customer relationships, non-compete agreements and backlog. The fair value of the developed technology totaling $26.3 million was calculated using the relief from royalty approach which is a variant of the income approach. The application of the relief from royalty approach involves estimating the value of an intangible asset by quantifying the present value of the stream of market derived royalty payments that the owner of the intangible asset is exempted or ‘relieved’ from paying. The developed technology has a useful life of 15 years. The fair value of the tradename totaling $13.7 million was calculated using the relief from royalty approach with a useful life of 15 years. The fair value of the acquired customer relationships totaling $26.6 million was calculated using the MPEEM approach and has a 15 year useful life. The fair value of the acquired

customer relationships was estimated by discounting the net cash flow derived from the expected revenues attributable to the acquired customer relationships. The fair value of the non-compete agreements was $1.0 million with a useful life of three years. The fair value of the customer backlog was $2.9 million with a useful life of one year.

Included in the purchase price consideration are contingent earn-out payments described above. Due to the nature of the earn-outs, a scenario based analysis using the probability of achieving the milestone expectations was used to value these contingent payments. These fair value measurements were based on unobservable inputs and are considered to be level 3 financial instruments.

In connection with the acquisition, the Company recorded on its consolidated balance sheet a liability of $14.0 million representing the fair value of contingent consideration payable. The fair value of this contingent consideration was remeasured as of June 30, 2022 and was $13.7 million as of June 30, 2022, and reductions of $0.4 million and $0.3 million was recorded in the unaudited interim condensed consolidated statement of operations for the three and six months ended June 30, 2022, respectively.

Included in Applied Cryo’s total net assets acquired, excluding goodwill, were net deferred tax liabilities of $16.5 million. In connection with the acquisition of these net deferred tax liabilities, the Company reduced its valuation allowance by $16.5 million and recognized a tax benefit $16.5 million during the year ended December 31, 2021.

The goodwill was primarily attributed to the value of synergies created with the Company’s current and future offerings and the value of the assembled workforce. Goodwill and intangible assets are not deductible for income tax purposes. Goodwill associated with the Applied Cryo acquisition was calculated as follows (in thousands):


Consideration paid	$	162,093
Less: net assets acquired		(69,365)
Total goodwill recognized	$	92,728

The acquisition of Applied Cryo contributed $16.2 million and $33.1 million to total consolidated revenue for the three and six months ended June 30, 2022, respectively. The Company determined it impractical to report net loss for the Applied Cryo acquisition for the three and six months ended June 30, 2022.

Frames Holding B.V. Acquisition

On December 9, 2021, the Company acquired 100% of the outstanding shares of Frames Holding B.V. (“Frames”). Frames, a leading provider of turnkey hydrogen solutions.

The preliminary allocation of the purchase price is still considered provisional due to outstanding customer valuation analysis. Identifiable intangible assets consisted of developed technology, tradename, acquired customer relationships, non-compete agreements and backlog. Any necessary adjustments will be finalized within one year from the date of acquisition. During the three months ended June 30, 2022, the Company recorded a measurement period adjustment to goodwill of $7.2 million due to the recording of the deferred tax treatment surrounding the tangible and intangible assets acquired, which was recorded to contingent consideration, loss accrual for service contracts, and other liabilities in the unaudited interim condensed consolidated balance sheet.

The fair value of the developed technology totaling $5.3 million was calculated using the relief from royalty approach which is a variant of the income approach, and it has a useful life of eight years. The fair value of the tradename totaling $11.6 million was calculated using the relief from royalty approach, and it has a useful life of eight years. The fair value of the acquired customer relationships totaling $27.2 million was calculated using the MPEEM approach which is a variant of the income approach, and it has a useful life of 17 years. The fair value of the customer relationships was estimated by discounting the net cash flow derived from the expected revenues attributable to the acquired customer relationships. The fair value of the non-compete agreements totaling $4.9 million was calculated using the with and without income approach, and it has a useful life of approximately four years. The fair value of the backlog was $1.4 million, and it has a useful life of one year.

Included in the purchase price consideration are contingent earn-out payments described above. Due to the nature of the earn-outs, a scenario based analysis using the probability of achieving the milestone expectations was used to determine the fair value of the contingent consideration. These fair value measurements were based on unobservable inputs and are considered to be level 3 financial instruments.

In connection with the acquisition, the Company recorded on its consolidated balance sheet a liability of $29.1 million representing the fair value of contingent consideration payable. The fair value of this contingent consideration was remeasured as of June 30, 2022 and was $28.0 million as of June 30, 2022. The change in fair value decline was partially due to a change in the foreign currency translation, partially offset by an increase in the liability. The Company recorded an adjustment of $1.4 million and $1.1 million for the three and six months ended June 30, 2022 in the unaudited interim condensed consolidated statement of operations.

Included in Frames’ total net assets acquired, excluding goodwill, are net deferred tax liabilities of $4.1 million.

5. Earnings Per Share

Basic earnings per common stock are computed by dividing net loss attributable to common stockholders by the weighted average number of common stock outstanding during the reporting period. In periods when we have net income, the shares of our common stock subject to the convertible notes outstanding during the period will be included in our diluted earnings per share under the if-converted method. Since the Company is in a net loss position, all common stock

3.75% Convertible Senior Notes

On May 18, 2020, the Company issued $200.0 million in aggregate principal amount of 3.75% Convertible Senior Notes due June 1, 2025, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). On May 29, 2020, the Company issued an additional $12.5 million in aggregate principal amount of 3.75% Convertible Senior Notes. During the three and six months ended June 30, 2022, there were no conversions of the 3.75% Convertible Senior Notes.

The 3.75% Convertible Senior Notes consisted of the following (in thousands):


	June 30,
	2022
Principal amounts:
Principal	$	197,278
Unamortized debt issuance costs (1)		(4,009)
Net carrying amount	$	193,269

Included in the unaudited interim condensed consolidated balance sheets within the 3.75% Convertible Senior Notes, net and amortized over the remaining life of the notes using the effective interest rate method.

The following table summarizes the total interest expense and effective interest rate related to the 3.75% Convertible Senior Notes (in thousands, except for effective interest rate):


	June 30,			June 30,
	2022			2021
Interest expense	$	1,849	$	1,850
Amortization of debt issuance costs		320		306
Total		2,169		2,156

Effective interest rate		4.5%		4.5%

Based on the closing price of the Company’s common stock of $16.57 on June 30, 2022, the if-converted value of the notes was greater than the principal amount. The estimated fair value of the note at June 30, 2022 was approximately $700 million. The fair value estimation was primarily based on an active stock exchange trade on June 14, 2022 of the 3.75% Convertible Senior Notes. See Note 15, “Fair Value Measurements,” for a description of the fair value hierarchy.

Capped Call

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

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

In connection with the issuance of the 5.5% Convertible Senior Notes, the Company entered into a forward stock purchase transaction (the “Common Stock Forward”), pursuant to which the Company agreed to purchase 14,397,906 shares of its common stock for settlement on or about March 15, 2023. On May 18, 2020, the Company amended and extended the maturity of the Common Stock Forward to June 1, 2025. The number of shares of common stock that the Company will ultimately repurchase under the Common Stock Forward is subject to customary anti-dilution adjustments. The Common Stock Forward is subject to early settlement or settlement with alternative consideration in the event of certain corporate transactions.

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

There were no shares of common stock settled in connection with the Common Stock Forward during the three and six months ended June 30, 2022. During the three and six months ended June 30, 2021, the Common Stock Forward was partially settled and 2.2 million shares and 8.1 million shares were received by the Company, respectively.

Contract costs

Contract costs consist of capitalized commission fees and other expenses related to obtaining or fulfilling a contract. Capitalized contract costs at June 30, 2022 and December 31, 2021 were $0.6 million and $0.4 million, respectively.

14. Income Taxes

The Company recorded $0.4 million and $0 of income tax expense for the three months ended June 30, 2022 and 2021, respectively. The Company recorded $9 thousand and $0 of income tax expense for the six months ended June 30, 2022 and 2021, respectively. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its domestic net deferred tax assets, which remain fully reserved.

Table of Contents

The domestic net deferred tax asset generated from the Company’s net operating loss has been offset by a full valuation allowance because it is more likely than not that the tax benefits of the net operating loss carry forward 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.

15. Fair Value Measurements

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

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

These levels are:

●

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

●

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

●

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

Securities reported at fair value utilizing Level 1 inputs represent assets whose fair value is determined based upon observable unadjusted quoted market prices for identical assets in active markets. Level 2 securities represent assets whose fair value is determined using observable market information such as previous day trade prices, quotes from less active markets or quoted prices of securities with similar characteristics. Available-for-sale securities are characterized as Level 2 assets, as their fair values are determined using observable market inputs. Equity securities are characterized as Level 1 assets, as their fair values are determined using active markets for identical assets. There were no transfers between Level 1, Level 2, or Level 3 for the three and six months ended June 30, 2022.

Financial instruments not recorded at fair value on a recurring basis include equity method investments that have not been remeasured or impaired in the current period, such as our investments in HyVia, AccionaPlug S.L., and SK Plug Hyverse Co., Ltd. During the three and six months ended June 30, 2022, the Company contributed approximately $0 and $22.6 million, respectively, to HyVia, AccionaPlug S.L. and SK Plug Hyverse Co., Ltd.

As of June 30, 2022, the remaining estimated fair value of contingent consideration for Giner ELX Inc. is $16.5 million. United Hydrogen Group Inc. was acquired in June 2020, and included in the purchase price was contingent consideration based on the future performance related to the expansion of the liquefication capacity of the Charleston, Tennessee liquid hydrogen plant. The Company’s liability for this contingent consideration was measured at fair value based on the Company’s expectations of achieving the expansion milestone. As of June 30, 2022, the remaining estimated fair value is $1.4 million. In the unaudited interim condensed consolidated

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

pending in the U.S. District Court for the Southern District of New York (the “Class Action”) and appointed a lead plaintiff. For previously reported information about the cases that were consolidated into the Class Action, refer to Part I, Item 3, “Legal Proceedings,” of the Company’s 2021 Form 10-K. On October 6, 2021, lead plaintiff filed a Consolidated Amended Class Action Complaint (the “Class Action Amended Complaint”) which asserts claims individually and on behalf of all persons who purchased or otherwise acquired the Company’s securities between November 9, 2020 and March 9, 2021 (the “Class”). The Class Action Amended Complaint includes two claims, for (1) violation of Section 10(b) of the exchange act and Rule 10b5 promulgated thereunder (against all defendants); and (2) violation of Section 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (against Mr. Marsh and Mr. Middleton). The Class Action Amended Complaint alleges that defendants made “materially false” statements concerning (1) adjusted EBITDA; (2) fuel delivery and research and development expenses; (3) costs related to provision for loss contracts; (4) gross losses; and (5) the effectiveness of internal controls and procedures, and that these alleged misstatements caused Class members losses and damages. The Class Action Amended Complaint seeks compensatory damages “in an amount to be proven at trial, including prejudgment interest thereon”; “reasonable costs and expenses incurred in th[e] action”; and “[s]uch other and further relief as the [c]ourt may deem just and proper.” On December 6, 2021, defendants filed a motion to dismiss the Class Action Amended Complaint. Briefing on the motion to dismiss was completed in March 2022.

On June 13, 2022, alleged Company stockholder Donna Max, derivatively on behalf of nominal defendant Plug, filed a complaint in the United States District Court for the District of Delaware against the derivative defendants named in the Liu Derivative Complaint, captioned Max v. Marsh, et. al., case no. 1:22-cv-00781(D. Del.)(the “Max Derivative Complaint”). The Max Derivative Complaint alleges that, for the years 2018, 2019 and 2020, the defendants did not “assure that a reliable system of financial controls was in place and functioning effectively”; “failed to disclose errors in the Company's accounting primarily relating to (i) the reported book value of right of use assets and related finance obligations, (ii) loss accruals for certain service contracts, (iii) the impairment of certain long-lived assets, and (iv) the classification of certain expenses previously included in research and development costs”; and that certain defendants traded Plug Power stock at “artificially inflated stock prices.” The Max Derivative Complaint asserts claims for (1) breach of fiduciary against all defendants; (2) breach of fiduciary duty for insider trading against certain defendants; and (3) contribution under Sections 10(b) and 21D of the Securities Exchange Act of 1934 against certain defendants. The Max Derivative Complaint seeks an award “for the damages sustained by [the Company]” and related relief. By stipulation approved by the Court, the case has been stayed pending the resolution of the motion to dismiss in the Securities Class action.

On June 29, 2022, alleged Company stockholder Abbas Khambati, derivatively on behalf of nominal defendant Plug, filed a complaint in the Court of Chancery in the State of Delaware against the derivative defendants named in the Liu Derivative Complaint and Gerard A. Conway, Jr. and Keith Schmid, captioned Khambati v. McNamee, et. al., C.A. no. 2022-05691(Del. Ch.)(the “Khambati Derivative Complaint”). The Khambati Derivative Complaint alleges that the defendants “deceive[d] the investing public, including stockholders of Plug Power, regarding the Individual Defendants’ management of Plug Power’s operations and the Company’s compliance with the SEC's accounting rules”; “facilitate[d” certain defendants’ sales of “their personally held shares while in possession of material, nonpublic information”; and “enhance[d] the Individual Defendants’ executive and directorial positions at Plug Power and the profits, power, and prestige that the Individual Defendants enjoyed as a result of holding these positions.” The Khambati Derivative Complaint asserts claims for (1) breach of fiduciary; and (2) disgorgement and unjust enrichment. The Khambati Derivative Complaint seeks an award “for the damages sustained by [the Company] as a result of the breaches” alleged or “disgorgement or restitution”; “disgorgement of insider trading profits” and “all profits, benefits and other compensation obtained by [defendants’] insider trading and further profits flowing therefrom”; an order “[d]irecting the Company to take all necessary actions to reform and improve its corporate governance and internal procedures”; and related relief. By stipulation approved by the Court, the case has been stayed pending the resolution of the motion to dismiss in the Securities Class action.

On July 19, 2022, alleged Company stockholder Anne D. Graziano, as Trustee of the Anne D. Graziano Revocable Living Trust, derivatively on behalf of nominal defendant Plug, filed a complaint in the Court of Chancery in the State of Delaware against the derivative defendants named in the Khambati Derivative Complaint, captioned Graziano v. Marsh, et. al., C.A. no. 2022-0629 (Del. Ch.)(the “Graziano Derivative Complaint”). The Graziano Derivative Complaint alleges that the director defendants (i) “either knowingly or recklessly issued or caused the Company to issue the materially false and misleading statements” concerning “certain critical accounting issues”; (ii) “willfully ignored, or recklessly failed to inform themselves of, the obvious problems with the Company’s internal

Table of Contents

controls, practices, and procedures, and failed to make a good faith effort to correct the problems or prevent their recurrence”; (iii) the members of the Audit Committee failed “to prevent, correct, or inform the Board of the issuance of material misstatements and omissions regarding critical accounting issues and the adequacy of the Company’s internal controls”; (iv) “received payments, benefits, stock options, and other emoluments by virtue of their membership on the Board and their control of the Company; (v) violated Plug’s Code of Conduct because they knowingly or recklessly engaged in and participated in making and/or causing the Company to make the materially false and misleading statements; and (vi) that certain defendants “sold large amounts of Company stock while it was trading at artificially inflated prices.” The Graziano Derivative Complaint asserts claims for (1) breach of fiduciary; (2) breach of fiduciary duty against certain defendants for insider trading; (3) unjust enrichment; (4) aiding and abetting breach of fiduciary duty; and (5) waste of corporate assets. The Graziano Derivative Complaint seeks an award of “the amount of damages sustained by the Company”; seeks an order “[d]irecting Plug Power to take all necessary actions to reform and improve its corporate governance and internal procedures to comply with applicable laws and to protect Plug Power and its stockholders from a repeat of the damaging events described herein”; and related relief. The parties to the Graziano Derivative Complaint and Khambati Derivative Complaint have agreed to consolidate their actions and have filed a stipulation with the Court to that effect and for a stay of the Graziano Derivative Complaint pending the resolution of the motion to dismiss in the Securities Class action.

As previously disclosed, on August 28, 2018, a lawsuit was filed on behalf of multiple individuals against the Company and five corporate co-defendants in the 9th Judicial District Court, Rapides Parish, Louisiana. The lawsuit relates to the previously disclosed May 2018 accident involving a forklift powered by the Company’s fuel cell at a Procter & Gamble facility in Louisiana. The lawsuit alleges claims against the Company and co-defendants, including Structural Composites Industries, Deep South Equipment Co., Air Products and Chemicals, Inc., and Hyster-Yale Group, Inc. for claims under the Louisiana Product Liability Act (“LPLA”) including defect in construction and/or composition, design defect, inadequate warning, breach of express warranty and negligence for wrongful death and personal injuries, among other damages. Procter & Gamble has intervened in that suit to recover worker’s compensation benefits paid to or for the employees/dependents. Procter & Gamble has also filed suit for property damage, business interruption, loss of revenue, expenses, and other damages. Procter & Gamble alleges theories under the LPLA, breach of warranty and quasi-contractual claims under Louisiana law. Defendants include the Company and several of the same co-defendants from the August 2018 lawsuit, including Structural Composites Industries, Deep South Equipment Co., and Hyster-Yale Group, Inc. In April 2022, Plug reached a settlement with respect to the individual plaintiffs on terms well below the Company’s commercial liability insurance limits and continues to vigorously defend the remaining lawsuit against Proctor & Gamble.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash, cash equivalents, restricted cash, accounts receivable and marketable securities. Cash and restricted cash are maintained in accounts with financial institutions, which, at times may exceed the Federal depository insurance coverage of $0.3 million. The Company has not experienced losses on these accounts and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant. The Company’s available-for-sale securities consists primarily of investments in U.S. Treasury securities and short-term high credit quality corporate debt securities. Equity securities are comprised of fixed income and equity market index mutual funds.

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

At June 30, 2022, two customers comprised 36.4% of the total accounts receivable balance. At December 31, 2021, one customer comprised approximately 46.6% of the total accounts receivable balance.

For purposes of assigning a customer to a sale/leaseback transaction completed with a financial institution, the Company considers the end user of the assets to be the ultimate customer. For the three and six months ended June 30, 2022, 38.0% and 35.5% of total consolidated revenues were associated with two customers, respectively. For the three and six months ended June 30, 2021, 81.3% and 77.7% of total consolidated revenues were associated primarily with three customers, respectively.

21. Segment Reporting

Our organization is managed from a sales perspective on the basis of “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 fuel cells and hydrogen producing equipment. Our chief executive officer was identified as the chief operating decision maker (CODM). All significant operating decisions made by management are largely based upon the analysis of Plug Power Inc. on a total company basis.

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.

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 to replace lead-acid and lithium batteries in electric material handling vehicles and industrial trucks for some of the world’s largest retail-distribution and manufacturing businesses, we have expanded our offerings to support a variety of commercial operations that can be powered with green hydrogen. We also provide electrolyzers that allow customers — such as refineries, producers of chemicals, steel and fertilizer and commercial refueling stations — to generate hydrogen on-site. Additionally, we intend for our electrolyzers to be used to generate green hydrogen within Plug’s own plants that will then be sold to customers. We are focusing our efforts on 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. Additionally, we manufacture and sell fuel cell products to replace batteries and diesel generators in stationary back-up

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. Europe has rolled out ambitious targets for the hydrogen economy and Plug is seeking to execute on its strategy to become one of the European leaders. This includes a targeted account strategy for material handling, securing strategic partnerships with European OEMs, energy companies, utility leaders and accelerating our electrolyzer business. Our global strategy includes leveraging a network of integrators or contract manufacturers. We manufacture our commercially viable products in Latham, New York, Rochester, New York, Houston, Texas and Spokane, Washington and support liquid hydrogen generation and logistics in Charleston, Tennessee.

Part of our long-term plan includes Plug penetrating the on-road vehicle market and large-scale stationary market. Plug’s formation of joint ventures with HyVia and Acciona Plug S.L. in Europe and SK Plug Hyverse Co., Ltd., in Asia not only support this goal but are expected to provide us with a more global footprint. Plug has been successful with acquisitions, strategic partnerships and joint ventures, and we plan to continue this mix.

Recent Developments

COVID-19 Update

Starting on January 3, 2022, all U.S. based employees, including temporary employees were required to either be vaccinated against COVID-19, or be subject to weekly COVID-19 testing in an effort to stop the spread of COVID-19 and continue to protect our workforce. As of February 28, 2022, we discontinued the weekly testing for unvaccinated employees and removed the mask requirement for fully vaccinated employees. Our positive cases declined significantly;

and that, combined with guidance from state and federal agencies resulted in the change in practice. We continue to monitor the situation, and remain prepared to adjust accordingly. On March 25, 2022, we transitioned our face-covering requirement to voluntary for all employees and visitors. Additionally, we removed our daily COVID-19 questionnaire and discontinued temperature monitoring as a daily requirement at our facilities. Employees are still expected to remain home if they are not feeling well and should contact our COVID team for future guidance. Furthermore, we have resumed all commercial air travel and all other non-critical travel, while also allowing employees to resume their personal travel. We have enabled third-party access to our facilities, and are continuing our normal janitorial and sanitary procedures. We no longer are requiring staggered shifts in our manufacturing facilities and are offering hybrid work schedules to those whose job function enabled them to do so.

We cannot predict at this time the full extent to which COVID-19 and its related variants will continue to impact our business, results, and financial condition, which will depend on many factors. We are staying in close communication with our manufacturing facilities, employees, customers, suppliers, and partners, and acting to mitigate the impact of this dynamic and evolving situation, but there is no guarantee that we will be able to do so. Many of the parts for our products are sourced from suppliers in China and the manufacturing situation in China remains variable. Supply chain disruptions could reduce the availability of key components, increase prices or both, as the COVID-19 pandemic has caused significant challenges for global supply chains resulting primarily in transportation delays. These transportation delays have caused incremental freight charges, which have negatively impacted our results of operations. We expect that these challenges will continue to have an impact on our businesses for the foreseeable future.

We continue to take proactive steps to limit the impact of these challenges and are working closely with our suppliers and transportation vendors to ensure availability of products and implement other cost savings initiatives. In addition, we continue to invest in our supply chain to improve its resilience with a focus on automation, dual sourcing of critical components and localized manufacturing when feasible. To date, there has been limited disruption to the availability of our products, though it is possible that more significant disruptions could occur if these supply chain challenges continue.

Inflation, Material Availability and Labor Shortages

In the first half of 2022, we continued to experience higher than expected commodity costs and supply chain costs, including logistics, procurement, and manufacturing costs, largely due to inflationary pressures. We expect this cost inflation to remain elevated through at least the remainder of 2022.

Our operations require significant amounts of necessary parts and raw materials. From time to time, the Company may encounter difficulties in obtaining certain raw materials or components necessary for production due to supply chain constraints and logistical challenges, which may also negatively impact the pricing of materials and components sourced or used by the Company. Additionally, conflicts abroad, such as the Russia-Ukraine conflict, may potentially contribute to issues related to supply chain disruptions and inflation impacts. While the Company does not currently anticipate any significant, broad-based difficulties in obtaining raw materials or components necessary for production, there have been supply chain and logistical challenges that have resulted in supply constraints and commodity price increases on certain raw materials and components used by the Company in production, as well as increased prices for freight and logistics, including air, sea and ground freight. Consequently, the Company may experience supply shortages for raw materials or components in the future, which could be further exacerbated by increased commodity prices as a result of additional inflationary pressures. Although we have offset a portion of these increased costs through price increases and operational efficiencies to date, there can be no assurance that we will be able to continue to do so. If we are unable to manage fluctuations through pricing actions, cost savings projects, and sourcing decisions as well as through productivity improvements, it may adversely impact our gross margins in future periods.

Additionally, we have observed an increasingly competitive labor market. Tight labor markets have resulted in labor inflation and longer times to fill open positions. Increased employee turnover, changes in the availability of our workers, including as a result of COVID-19-related absences, and labor shortages in our supply chain have resulted in, and could continue to result in, increased costs which could negatively affect our financial condition, results of operations, or cash flows.

This increase was primarily related to increased headcount, which resulted in increased salaries and stock-based compensation, as well as branding expenses.

Selling, general and administrative expenses for the six months ended June 30, 2022, increased $112.6 million, or 175.3%, to $176.8 million from $64.2 million for the six months ended June 30, 2021. This increase was primarily related to increased headcount, which resulted in increased salaries and stock-based compensation, as well as branding expenses.

Contingent consideration. The fair value of the contingent consideration related to the Giner ELX, Inc., United Hydrogen Group Inc, Frames, Applied Cryo and Joule acquisitions was remeasured as of June 30, 2022, which resulted in a $5.1 million benefit for the three months ended June 30, 2022 and a $2.6 million benefit for the six months ended June 30, 2022, both of which are reflected in the unaudited interim condensed consolidated statement of operations for the three and six months ended June 30, 2022, 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 and six months ended June 30, 2022 increased $2.4 million and $4.4 million, respectively, as compared to the three and six months ended June 30, 2021. The increase is primarily related to the increase in the investment portfolio during 2022.

Interest expense. Interest expense consists of interest expense related to our long-term debt, convertible senior notes, obligations under finance leases and our finance obligations. Interest expense for the three months ended June 30, 2022 decreased $0.5 million compared to the three months ended June 30, 2021, primarily related to a decrease in long-term debt and an increase in capitalized interest, offset by an increase in finance obligations. Interest expense for the six months ended June 30, 2022 decreased $4.2 million compared to the six months ended June 30, 2021, primarily related to a decrease in long-term debt and an increase in capitalized interest, offset by an increase in finance obligations.

Critical Accounting Estimates

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these unaudited interim condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of and during the reporting period. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, bad debts, inventories, goodwill and intangible assets, valuation of long-lived assets, accrual for service loss contracts, operating and finance leases, product warranty accruals, unbilled revenue, common stock warrants, income taxes, 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.

There have been no changes in our critical accounting estimates from those reported in our 2021 Form 10-K.

Item 3 — Quantitative and Qualitative Disclosures about Market Risk

There has been no material change from the information provided in the Company’s 2021 Form 10-K under the section titled “Item 7A: Quantitative and Qualitative Disclosures About Market Risk.”

Item 4 — Controls and Procedures

(a)

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

Table of Contents

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 the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective in 2018, 2019, 2020 and 2021 because of the material weaknesses in internal control over financial reporting described in Part II, Item 9A “Controls and Procedures” of our 2021 Form 10-K. The material weaknesses have not been remediated as of June 30, 2022.

Material Weakness

Management identified that the following deficiency existed in internal control over financial reporting in 2018, 2019, 2020 and 2021: the Company did not maintain a sufficient complement of trained, knowledgeable resources to execute its responsibilities with respect to internal control over financial reporting for certain financial statement accounts and disclosures. As a consequence, the Company did not conduct an effective risk assessment process that was responsive to changes in the Company's operating environment and did not design and implement effective process-level controls in the following areas:

(a)

presentation of operating expenses;

(b)

accrual for loss contracts related to service; and

(c)

identification of adjustments to physical inventory.

As of December 31, 2021, management identified additional deficiencies which were also the result of the Company not maintaining a sufficient complement of trained, knowledgeable resources to execute its responsibilities and conduct an effective risk assessment. Specifically, the process-level controls to ensure proper capitalization of inventory costs were not performed with an appropriate level of precision to detect and prevent a material misstatement. Additionally, management identified ineffective general information technology control activities over an information technology system that is used in calculating fuel billings, due to the ineffective risk assessment in identifying the relevant system. Management did not design and implement general information technology control activities in response to the current year growth in fuel delivered to customers.

The control deficiency, related to the accrual for loss contracts related to service, resulted in a material misstatement that was corrected prior to the filing of the 2021 Form 10-K. We did not identify any other material misstatements to the consolidated financial statements and there were no changes to previously issued financial results as a result of the other control deficiencies; however, the control deficiencies described above created a reasonable possibility that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis. As a result, we concluded the deficiencies described above represent material weaknesses in our internal control over financial reporting, and our internal control over financial reporting was not effective as of December 31, 2021.

The Company acquired Applied Cryo Technologies and Frames Holdings B.V. (together, the “Acquired Companies”) during 2021, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, the Acquired Companies’ internal control over financial reporting associated with total assets of $369.1 million and total revenues of $15.8 million included in the consolidated financial statements of the Company as of and the year ended December 31, 2021.

Table of Contents

Remediation Activities

As reported on our 2021 Form 10-K, we continue to take steps to remediate this material weakness and will continue to take further steps until such remediation is complete. These steps include the following:

Hiring additional resources, including third-party resources, with the appropriate technical accounting expertise, and strengthening internal training, to assist us in identifying and addressing any complex technical accounting issues that affect our consolidated financial statements.

Designing and implementing a comprehensive and continuous risk assessment process to identify and assess risks of material misstatements, and ensure that the impacted financial reporting processes and related internal controls are properly designed, maintained, and documented to respond to those risks in our financial reporting.

Implementing more structured analysis and review procedures and documentation for the application of GAAP, complex accounting matters, and key accounting policies.

Augmenting our current estimation policies and procedures to be more robust and in-line with overall market dynamics, including an evaluation of our operating environment, in order to ensure operating effectiveness of certain process-level control activities.

Deploying new tools and tracking mechanisms to help enhance and maintain the appropriate documentation surrounding our classification of operating expenses.

Further enhancing our policies, procedures, and controls related to physical inventory counting both in interim periods and at year-end.

Implementing general information technology controls over our information technology system used in calculating fuel billings.

Implementing structured analysis and review procedures around the manual processes related to capitalization of inventory costs.

Reporting regularly to the Company’s Audit Committee on the progress and results of the remediation plan, including the identification, status, and resolution of internal control deficiencies.

As we work to improve our internal control over financial reporting, we may modify our remediation plan and may implement additional measures as we continue to review, optimize, and enhance our financial reporting controls and procedures in the ordinary course. The material weaknesses will not be considered remediated until the remediated controls have been operating for a sufficient period of time and can be evidenced through testing that these controls are operating effectively.

(c) Changes in internal control over financial reporting

Exclusive of the steps taken as part of the remediation activities, there were no changes in the Company’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2022 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
