1. Nature of Operations

Plug Power is facilitating the paradigm shift to an increasingly electrified world by innovating cutting-edge hydrogen and fuel cell solutions. In our core business, we provide and continue to develop commercially viable hydrogen and fuel cell product solutions to replace lead-acid batteries in electric material handling vehicles and industrial trucks for some of the world’s largest retail-distribution and manufacturing businesses. 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 backup power applications. These products have proven valuable with telecommunications, transportation, and utility customers as robust, reliable, and sustainable power solutions.

Our current products and services include:

GenDrive: GenDrive is our hydrogen fueled Proton Exchange Membrane (“PEM”) fuel cell system providing power to material handling electric vehicles, including class 1, 2, 3 and 6 electric forklifts, Automated Guided Vehicles (“AGVs”) and ground support equipment;

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

GenCare: GenCare is our ongoing ‘internet of things’-based maintenance and on-site service program for GenDrive fuel cell systems, GenSure fuel cell systems, GenFuel hydrogen storage and dispensing products and ProGen fuel cell engines;

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

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;

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

GenFuel Electrolyzers: GenFuel electrolyzers are modular, scalable hydrogen generators optimized for clean hydrogen production. Electrolyzers generate hydrogen from water using electricity and a special membrane and “green” hydrogen is generated by using renewable energy inputs, such as solar or wind power.

We provide our products worldwide through our direct product sales force, and by leveraging relationships with original equipment manufacturers (“OEMs”) and their dealer networks. Plug Power is targeting Asia and Europe for expansion in adoption. Europe has rolled out ambitious targets for the hydrogen economy and Plug Power is executing on its strategy to become one of the European leaders. This includes a targeted account strategy for material handling as well as securing strategic partnerships with European OEMs, energy companies, utility leaders and accelerating our electrolyzer business. We manufacture our commercially viable products in Latham, New York, Rochester, New York and Spokane, Washington and support liquid hydrogen generation and logistics in Charleston, Tennessee.

Our wholly-owned subsidiary, Plug Power France, has created a joint venture with Renault SAS (“Renault”) named HyVia, a French société par actions simplifiée (“HyVia”). HyVia plans to manufacture and sell fuel cell powered electric light commercial vehicles (“FCELCVs”) and to supply hydrogen fuel and fueling stations to support the FCE-LCV market, in each case primarily in Europe. HyVia is owned 50% by Plug Power France and 50% by Renault.

2. Summary of Significant Accounting Policies

Restatement

As previously disclosed in the Explanatory Note to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “2020 10-K”), the Company restated its previously issued audited consolidated financial statements as of and for the years ended December 31, 2019 and 2018 and its unaudited interim condensed consolidated financial statements as of and for each of the quarterly periods ended March 31, 2020 and 2019, June 30, 2020 and 2019, September 30, 2020 and 2019 and December 31, 2019.

Previously filed annual reports on Form 10-K and quarterly reports on Form 10-Q for the periods affected by the restatement have not been amended. Accordingly, investors should not rely upon the Company’s previously released financial statements for these periods and any earnings releases or other communications relating to these periods, and, for these periods, investors should rely solely on the financial statements and other financial data for the relevant periods included in the 2020 10-K. Commencing with our quarterly report on Form 10-Q for the quarterly period ended March 31, 2021, we are including in our quarterly reports for fiscal 2021 restated results for the corresponding interim periods of fiscal 2020.

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 HyVia using the equity method based on our economic ownership interest and our ability to exercise significant influence over the operating and financial decisions of HyVia.

Interim Financial Statements

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

Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s 2020 10-K.

The information presented in the accompanying unaudited interim condensed consolidated balance sheets as of December 31, 2020 has been derived from the Company’s December 31, 2020 audited consolidated financial statements.

There have been no changes in our accounting policies from those reported in our 2020 10-K, except for the adoption of Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), as described in the Recently Adopted Accounting Guidance section. We have also expanded our accounting policy relating to cash equivalents, and available-for-sale securities as follows:

Cash Equivalents

The Company considers all highly-liquid debt securities with original maturities of three months or less to be cash equivalents. At June 30, 2021, cash equivalents consisted of commercial paper and U.S. Treasury securities with original maturities of three months or less, and money market funds. Due to their short-term nature, the carrying amounts reported in the unaudited interim condensed consolidated balance sheets approximate the fair value of cash and cash equivalents.

Table of Contents

Available-for-sale securities

Available-for-sale securities is comprised of commercial paper with original maturities greater than three months, U.S. Treasury securities, municipal debt, certificates of deposit and corporate bonds. We consider these securities to be available for use in our current year operations, and therefore classify them as current even if we do not dispose of the securities in the following year.

Available-for-sale securities are recorded at fair value as of each balance sheet date. As of each balance sheet date, unrealized gains and losses, with the exception of credit related losses, are recorded to accumulated other comprehensive income. Any credit related losses are recognized as a credit loss allowance on the balance sheet with a corresponding adjustment to operations. Realized gains and losses are due to the sale and maturity of securities classified as available-for-sale and represent the net gain (loss) from accumulated other comprehensive income reclassifications for previously unrealized net gains on available-for-sale debt securities.

Equity securities

Equity securities are comprised of fixed income and equity market index mutual funds. Equity securities are valued at fair value with changes in the fair value recognized in our unaudited interim condensed consolidated statement of operations. We consider these securities to be available for use in our current year operations, and therefore classify them as current even if we do not dispose of the securities in the following year.

Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

Other than the adoption of the accounting guidance mentioned in our 2020 10-K and ASU 2020-06, there have been no other significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements.

On January 1, 2021, we early adopted ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) using the modified retrospective approach. Consequently, the Company’s 3.75% Convertible Senior Notes due 2025 (the “3.75% Convertible Senior Notes”) is now accounted for as a single liability measured at its amortized cost. This accounting change removed the impact of recognizing the equity component of the Company’s convertible notes at issuance and the subsequent accounting impact of additional interest expense from debt discount amortization. Future interest expense of the convertible notes will be lower as a result of adoption of this guidance and net loss per share will be computed using the if-converted method for convertible instruments. The cumulative effect of the accounting change upon adoption on January 1, 2021 increased the carrying amount of the 3.75% Convertible Senior Notes by $120.6 million, reduced accumulated deficit by $9.6 million and reduced additional paid-in capital by $130.2 million.

Recent Accounting Guidance Not Yet Effective

All issued but not yet effective accounting and reporting standards as of June 30, 2021 are either not applicable to the Company or are not expected to have a material impact on the Company.

3. Extended Maintenance Contracts

On a quarterly basis, we evaluate any potential losses related to our extended maintenance contracts for fuel cell systems and related infrastructure that has been sold. We measure impairment losses at the customer contract level. The expected revenues and expenses for these contracts include all applicable expected costs of providing services over the remaining term of the contracts and the related unearned net revenue. A loss is recognized if the sum of expected costs of providing services under the contract exceeds related unearned net revenue and is recorded as a provision for loss contracts related to service in the consolidated statements of operations. A key component of these estimates is the expected future service costs. In estimating the expected future costs, the Company considers its current service cost level and applies significant judgment related to expected cost saving initiatives. The expected future cost savings will be primarily dependent upon the success of the Company’s initiatives related to increasing stack life, achieving better economies of

scale for service labor, and improvements in design and operations of infrastructure. If the expected cost saving initiatives are not realized, this will increase the costs of providing services and could adversely affect our estimated contract loss accrual.

The following table shows the rollforward of balance in the accrual for loss contracts, including changes due to the passage of time, additions, and changes in estimates (in thousands):


	Six months ended		Year ended

Released to Provision for Warrants		—		(12,814)
Ending Balance	$	28,412	$	24,013

4. 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. After January 1, 2021, the date of the adoption of ASU 2020-06, 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 equivalents would be considered anti-dilutive and are therefore not included in the determination of diluted earnings per share. Accordingly, basic and diluted loss per share are the same.

The potentially dilutive securities are summarized as follows:


	At June 30,
	2021	2020
Stock options outstanding (1)	9,165,066	16,273,120

9. Long-Term Debt

In March 2019, the Company entered into a loan and security agreement, as amended (the “Loan Agreement”), with Generate Lending, LLC (“Generate Capital”), providing for a secured term loan facility in the amount of $100 million (the “Term Loan Facility”).

During the year ended December 31, 2020, the Company, under another series of amendments to the Loan Agreement, borrowed an incremental $100.0 million. As part of the amendment to the Loan Agreement, the Company’s interest rate on the secured term loan facility was reduced to 9.50% from 12.00% per annum, and the maturity date was extended to October 31, 2025 from October 6, 2022. On June 30, 2021, the outstanding balance under the Term Loan Facility was $150.8 million. In addition to the Term Loan Facility, on June 30, 2021 there was approximately $10.0 million of debt related to United Hydrogen Group, Inc. acquisition.

The Loan Agreement includes covenants, limitations, and events of default customary for similar facilities. Interest and a portion of the principal amount is payable on a quarterly basis. Principal payments are funded in part by releases of restricted cash, as described in Note 19, “Commitments and Contingencies.” Based on the amortization schedule as of June 30, 2021, the aforementioned loan balance under the Term Loan Facility will be fully paid by October 31, 2025. The Company is in compliance with, or has obtained waivers for, all debt covenants.

The Term Loan Facility is secured by substantially all of the Company’s and the guarantor subsidiaries’ assets, including, among other assets, all intellectual property, all securities in domestic subsidiaries and 65% of the securities in foreign subsidiaries, subject to certain exceptions and exclusions.

The Loan Agreement provides that if there is an event of default due to the Company’s insolvency or if the Company fails to perform in any material respect the servicing requirements for fuel cell systems under certain customer agreements, which failure would entitle the customer to terminate such customer agreement, replace the Company or withhold the payment of any material amount to the Company under such customer agreement, then Generate Capital has the right to cause Proton Services Inc., a wholly owned subsidiary of the Company, to replace the Company in performing the maintenance services under such customer agreement.

10. Convertible Senior Notes

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.

At issuance in May 2020, the total net proceeds from the 3.75% Convertible Senior Notes were as follows:


	Amount

Table of Contents

Less initial purchasers' discount		(6,374)
Less cost of related capped calls		(16,253)
Less other issuance costs		(617)
Net proceeds	$	189,219

The 3.75% Convertible Senior Notes bear interest at a rate of 3.75% per year, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2020. The notes will mature on June 1, 2025, unless earlier converted, redeemed or repurchased in accordance with their terms.

The 3.75% Convertible Senior Notes are senior, unsecured obligations of the Company and rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the notes, equal in right of payment to any of the Company’s existing and future liabilities that are not so subordinated, including the Company’s $100 million in aggregate principal amount of the 5.5% Convertible Senior Notes, effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to all indebtedness and other liabilities, including trade payables, of its current or future subsidiaries.

Holders of the 3.75% Convertible Senior Notes may convert their notes at their option at any time prior to the close of the business day immediately preceding December 1, 2024 in the following circumstances:

during any calendar quarter commencing after March 31, 2021 if the last reported sale price of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter;

during the five business days after any five consecutive trading day period (such five consecutive trading day period, the measurement period) in which the trading price per $1,000 principal amount of the 3.75% Convertible Senior Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

if the Company calls any or all of the 3.75% Convertible Senior Notes for redemption, any such notes that have been called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

upon the occurrence of specified corporate events, as described in the indenture governing the 3.75% Convertible Senior Notes.

On or after December 1, 2024, the holders of the 3.75% Convertible Senior Notes may convert all or any portion of their notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions.

The initial conversion rate for the 3.75% Convertible Senior Notes is 198.6196 shares of the Company’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $5.03 per share of the Company’s common stock, subject to adjustment upon the occurrence of specified events. Upon conversion, the Company will pay or deliver, as applicable, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. During the three months ended June 30, 2021, certain conditions allowing holders of the 3.75% Convertible Senior Notes to convert were met. The 3.75% Convertible Senior Notes are therefore convertible during the calendar quarter ending September 30, 2021 at the conversion rate discussed above. During the six months ended June 30, 2021, $15.2 million of the 3.75% Convertible Senior Notes were converted and the Company issued 3.0 million shares of common stock in conjunction with these conversions.

Table of Contents

In addition, following certain corporate events or following issuance of a notice of redemption, the Company will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called for redemption during the related redemption period in certain circumstances.

The 3.75% Convertible Senior Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after June 5, 2023 and before the 41^st scheduled trading day immediately before the maturity date, at a cash redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including at least one of the three trading days immediately preceding the date the Company sends the related redemption notice, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company sends such redemption notice.

If the Company undergoes a “fundamental change” (as defined in the Indenture), holders may require the Company to repurchase their notes for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, to, but excluding, the fundamental change repurchase date.

The Company accounts for the 3.75% Convertible Senior Notes as a liability. We incurred transaction costs related to the issuance of the 3.75% Convertible Senior Notes of approximately $7.0 million, consisting of initial purchasers’ discount of approximately $6.4 million and other issuance costs of $0.6 million which were recorded as debt issuance cost (presented as contra debt in the unaudited interim condensed consolidated balance sheets) and are being amortized to interest expense over the term of the 3.75% Convertible Senior Notes.

Total		2,156

Effective interest rate		4.50%

Based on the closing price of the Company’s common stock of $34.19 on June 30, 2021, the if-converted value of the notes was greater than the principal amount. The estimated fair value of the note at June 30, 2021 was approximately $1.3 billion. The fair value estimation was primarily based on an active stock exchange trade on June 24, 2021 of the 3.75% Senior Convertible Note. See Note 15, “Fair Value Measurements,” for a description of the fair value hierarchy.

Capped Call

Table of Contents

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.

5.5% Convertible Senior Notes

In March 2018, the Company issued $100.0 million in aggregate principal amount of the 5.5% Convertible Senior Notes due on March 15, 2023, in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act.

In May 2020, the Company used a portion of the net proceeds from the issuance of the 3.75% Convertible Senior Notes to finance the cash portion of the partial repurchase of the 5.5% Convertible Senior Notes, which consisted of a repurchase of approximately $66.3 million in aggregate principal amount of the 5.5% Convertible Senior Notes in privately-negotiated transactions for aggregate consideration of $128.9 million, consisting of approximately $90.2 million in cash and approximately 9.4 million shares of the Company’s common stock. The partial repurchase of the 5.5% Convertible Senior Notes resulted in a $13.2 million gain on early debt extinguishment. In the fourth quarter of 2020, $33.5 million of the remaining 5.5% Convertible Senior Notes were converted into 14.6 million shares of common stock which resulted in a gain of approximately $4.5 million which was recorded on the consolidated statement of operations on the gain (loss) on extinguishment of debt line.

On January 7, 2021, the remaining aggregate principal of $160 thousand aggregate principal amount of the 5.5% Convertible Senior Notes were converted into 69,808 shares of common stock. Interest expense and amortization for the period were immaterial.

Capped Call

In conjunction with the pricing of the 5.5% Convertible Senior Notes, the Company entered into privately negotiated capped call transactions (the “5.5% Notes Capped Call”) with certain counterparties at a price of $16.0 million to reduce the potential dilution to the Company’s common stock upon any conversion of the 5.5% Convertible Senior Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted 5.5% Convertible Senior Notes, as the case may be. The net cost incurred in connection with the 5.5% Notes Capped Call has been recorded as a reduction to additional paid-in capital in the unaudited interim condensed consolidated balance sheets.

In conjunction with the pricing of the partial repurchase of the 5.5% Convertible Senior Notes, the Company terminated 100% of the 5.5% Notes Capped Call on June 5, 2020. As a result of the termination, the Company received $24.2 million, which was recorded in additional paid-in capital in the unaudited interim condensed consolidated balance sheets.

Common Stock Forward

In connection with the issuance of the 5.5% Convertible Senior Notes, the Company also 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. In connection with the issuance of the 3.75% Convertible Senior Notes and the partial repurchase of the 5.5% Convertible Senior Notes, the Company amended and extended the maturity of the Common Stock Forward to June 1, 2025. The number of shares of common stock that

Table of Contents

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 5.5% Notes Capped Call and Common Stock Forward are not remeasured.

Amazon Transaction Agreement

On April 4, 2017, the Company and Amazon entered into a Transaction Agreement (the “Amazon Transaction Agreement”), pursuant to which the Company agreed to issue to Amazon.com NV Investment Holdings LLC, a wholly owned subsidiary of Amazon, a warrant (the “Amazon Warrant”) to acquire up to 55,286,696 shares of the Company’s common stock (the “Amazon Warrant Shares”), subject to certain vesting events described below. The Company and Amazon entered into the Amazon Transaction Agreement in connection with existing commercial agreements between the Company and Amazon with respect to the deployment of the Company’s GenKey fuel cell technology at Amazon distribution centers. The existing commercial agreements contemplate, but do not guarantee, future purchase orders for the Company’s fuel cell technology. The vesting of the Amazon Warrant Shares was conditioned upon payments made by Amazon or its affiliates (directly or indirectly through third parties) pursuant to the existing commercial agreements.

Under the terms of the original Amazon Warrant, the first tranche of the 5,819,652 Amazon Warrant Shares vested upon execution of the Amazon Warrant, and the remaining Amazon Warrant Shares vest based on Amazon’s payment of up to $600.0 million to the Company in connection with Amazon’s purchase of goods and services from the Company. The $6.7 million fair value of the first tranche of the Amazon Warrant Shares, was recognized as selling, general and administrative expense upon execution of the Amazon Warrant.

Provision for the second and third tranches of Amazon Warrant Shares is recorded as a reduction of revenue, because they represent consideration payable to a customer.

The fair value of the second tranche of Amazon Warrant Shares was measured at January 1, 2019, upon adoption of ASU 2019-08. The second tranche of 29,098,260 Amazon Warrant Shares vested in 4 equal installments, as Amazon or its affiliates, directly or indirectly through third parties, made an aggregate of $50.0 million in payments for goods and services to the Company, up to payments totaling $200.0 million in the aggregate. The last installment of the second tranche vested on November 2, 2020. Revenue reductions of $9.0 million, $4.1 million and $9.8 million associated with the second tranche of Amazon Warrant Shares were recorded in 2020, 2019 and 2018, respectively, under the terms of the original Amazon Warrant.

Under the terms of the original Amazon Warrant, the third tranche of 20,368,784 Amazon Warrant Shares vests in 8 equal installments, as Amazon or its affiliates, directly or indirectly through third parties, made an aggregate of $50.0 million in payments for goods and services to the Company, up to payments totaling $400.0 million in the aggregate. The measurement date for the third tranche of Amazon Warrant Shares was November 2, 2020, when their exercise price was determined, as discussed further below. The fair value of the third tranche of Amazon Warrant Shares was determined to be $10.57 each. During 2020, revenue reductions of $24.1 million associated with the third tranche Amazon Warrant Shares were recorded under the terms of the original Amazon Warrant, prior to the December 31, 2020 waiver described below.

On December 31, 2020, the Company waived the remaining vesting conditions under the Amazon Warrant, which resulted in the immediate vesting of all the third tranche of the Amazon Warrant Shares and recognition of an additional $399.7 million reduction to revenue.

Table of Contents

The $399.7 million reduction to revenue resulting from the December 31, 2020 waiver was determined based upon a probability assessment of whether the underlying shares would have vested under the terms of the original Amazon Warrant. Based upon the Company’s projections of probable future cash collections from Amazon (i.e., a Type I share based payment modification), a reduction of revenue associated with 5,354,905 Amazon Warrant Shares was recognized at their previously measured November 2, 2020 fair value of $10.57 per warrant. A reduction of revenue associated with the remaining 12,730,490 Amazon Warrant Shares was recognized at their December 31, 2020 fair value of $26.95 each, based upon the Company’s assessment that associated future cash collections from Amazon were not deemed probable (i.e., a Type III share based payment modification).

The $399.7 million reduction to revenue was recognized during the year ended December 31, 2020 because the Company concluded such amount was not recoverable from the margins expected from future purchases by Amazon under the Amazon Warrant, and no exclusivity or other rights were conferred to the Company in connection with the December 31, 2020 waiver. Additionally, for the year ended December 31, 2020, the Company recorded a reduction to the provision for warrants of $12.8 million in connection with the release of the service loss accrual.

At December 31, 2020, all 55,286,696 of the Amazon Warrant Shares had vested. For service contracts entered into prior to December 31, 2020, the warrant charge associated with that revenue was capitalized and is subsequently amortized over the life of the service contract. The total amount of provision for common stock warrants recorded as a reduction of revenue for the Amazon Warrant during the three months ended June 30, 2021 and 2020 was $105 thousand and $3.4 million, respectively. The amount of provision for common stock warrants recorded as a reduction of revenue for the Amazon Warrant during the six months ended June 30, 2021 and 2020 was $209 thousand and $4.7 million, respectively. During the three months ended March 31, 2021 and June 30, 2021, the Amazon Warrant was exercised with respect to 9,214,449 shares of common stock and 4,745,905 shares of common stock. In July 2021, the Amazon Warrant was exercised with respect to an additional 3,501,640 shares of common stock.

The exercise price for the first and second tranches of Amazon Warrant Shares was $1.1893 per share. The exercise price of the third tranche of Amazon Warrant Shares was $13.81 per share, which was determined pursuant to the terms of the Amazon Warrant as an amount equal to 90 percent (90%) of the 30-day volume weighted average share price of the Company’s common stock as of November 2, 2020, the final vesting date of the second tranche of Amazon Warrant Shares. The Amazon Warrant is exercisable through April 4, 2027. The Amazon Warrant provides for net share settlement that, if elected by the holder, will reduce the number of shares issued upon exercise to reflect net settlement of the exercise price. The Amazon Warrant provides for certain adjustments that may be made to the exercise price and the number of shares of common stock issuable upon exercise due to customary anti-dilution provisions based on future events. The Amazon Warrant is classified as an equity instrument.

Fair value of the Amazon Warrant at December 31, 2020 and November 2, 2020 was based on the Black Scholes Option Pricing Model, which is based, in part, upon level 3 unobservable inputs for which there is little or no market data, requiring the Company to develop its own assumptions.

The Company used the following assumptions for its Amazon Warrant:


	December 31, 2020	November 2, 2020
Risk-free interest rate	0.58%	0.58%
Volatility	75.00%	75.00%
Expected average term	6.26	6.42

The first tranche of 5,819,652 Walmart Warrant Shares vested upon the execution of the Walmart Warrant and was fully exercised as of December 31, 2020. Accordingly, $10.9 million, the fair value of the first tranche of Walmart Warrant Shares, was recorded as a provision for common stock warrants and presented as a reduction to revenue on the consolidated statements of operations during 2017. All future provision for common stock warrants is measured based on their grant-date fair value and recorded as a charge against revenue. The second tranche of 29,098,260 Walmart Warrant Shares vests in 4 installments of 7,274,565 Walmart Warrant Shares each time Walmart or its affiliates, directly or indirectly through third parties, make an aggregate of $50.0 million in payments for goods and services to the Company, up to payments totaling $200.0 million in the aggregate. The exercise price for the first and second tranches of Walmart Warrant Shares is $2.1231 per share. After Walmart has made payments to the Company totaling $200.0 million, the third tranche of 20,368,784 Walmart Warrant Shares will vest in 8 installments of 2,546,098 Walmart Warrant Shares each time Walmart or its affiliates, directly or indirectly through third parties, make an aggregate of $50.0 million in payments for goods and services to the Company, up to payments totaling $400.0 million in the aggregate. The exercise price of the third tranche of Walmart Warrant Shares will be an amount per share equal to ninety percent (90%) of the 30-day volume weighted average share price of the common stock as of the final vesting date of the second tranche of Walmart Warrant Shares, provided that, with limited exceptions, the exercise price for the third tranche will be no lower than $1.1893. The Walmart Warrant is exercisable through July 20, 2027.

14. Income Taxes

The Company did 0t record any income tax expense or benefit for the three or six months ended June 30, 2021. The Company recognized an income tax benefit for the three and six months ended June 30, 2020 of $17.4 million. Income tax benefit for the three and six months ended June 30, 2020 included $12.2 million resulting from the intraperiod tax allocation rules under Accounting Standards Codification (“ASC”) Topic 740-20, Intraperiod Tax Allocation, under which the Company recognized an income tax benefit resulting from a source of future taxable income attributable to the net credit to additional paid-in capital related to the issuance of the 3.75% Convertible Senior Notes, offset by the partial extinguishment of the 5.5% Convertible Senior Notes. In addition, the Company recorded $5.2 million of income tax benefit for the three and six months ended June 30, 2020 related to the recognition of net deferred tax liabilities in connection with the Giner, ELX Inc. acquisition, which resulted in a corresponding reduction in our deferred tax asset valuation allowance. The Company has not changed its overall conclusion with respect to the need for a valuation allowance against its net deferred tax assets, which remain fully reserved.

The 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.

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.

The fair values of the Company’s investments are based upon prices provided by an independent pricing service. Management has assessed and concluded that these prices are reasonable and has not adjusted any prices received from the independent provider. 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. There were 0 transfers between Level 1, Level 2, or Level 3 during the six months ended June 30, 2021.

19. Commitments and Contingencies

Restricted Cash

In connection with certain of the above noted sale/leaseback agreements, cash of $243.5 million was required to be restricted as security as of June 30, 2021, which restricted cash will be released over the lease term. As of June 30, 2021, the Company also had certain letters of credit backed by restricted cash totaling $143.7 million that are security for the above noted sale/leaseback agreements.

Litigation

Legal matters are defended and handled in the ordinary course of business. 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. The Company has not recorded any accruals related to any legal matters.

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 $0.25 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 commercial paper, U.S. Treasury securities, municipal debt 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, 2021, 1 customer comprised 78.5% of the total accounts receivable balance. At December 31, 2020, 3 customers comprised 73.9% 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, 2021, 81.3% and 77.7%, of total consolidated revenues were associated with 3 customers, respectively. For the three and six months ended June 30, 2020, 83.9% and 77.9% of total consolidated revenues were associated primarily with 2 customers, respectively.

20. Employee Benefit Plans

2011 Stock Option and Incentive Plan

On May 12, 2011, the Company’s stockholders approved the 2011 Stock Option and Incentive Plan (the “2011 Plan”). The 2011 Plan provided for the issuance of up to a maximum number of shares of common stock equal to the sum of (i) 1,000,000, plus (ii) the number of shares of common stock underlying any grants pursuant to the 2011 Plan or the Plug Power Inc. 1999 Stock Option and Incentive Plan that are forfeited, canceled, repurchased or are terminated (other than by exercise). The shares may be issued pursuant to stock options, stock appreciation rights, restricted stock awards and certain other equity-based awards granted to employees, directors and consultants of the Company. NaN further grants may be made under the 2011 Plan after May 12, 2021. Through various amendments to the 2011 Plan approved by the Company’s stockholders, the number of shares of the Company’s common stock authorized for issuance under the 2011 Plan has been increased to 42.4 million. The Company recorded expense of approximately $11.1 million and $2.5 million, for the three months ended June 30, 2021 and 2020, respectively, in connection with the 2011 Plan. The Company recorded

Table of Contents

expense of approximately $19.6 million and $5.0 million, for the six months ended June 30, 2021 and 2020, respectively, in connection with the 2011 Plan. In July 2021, the 2021 Stock Option Incentive Plan (the “2021 Plan”) was approved by the Company’s stockholders, which provides for the sum of 22,500,000 shares in addition to 473,491 shares of common stock that are available for grant under the 2011 Plan to be issued under the 2021 Plan.

At June 30, 2021, there were outstanding options to purchase approximately 9.2 million shares of common stock. Options for employees issued under this plan generally vest in equal annual installments over three years and expire ten years after issuance. Options granted to members of the Board generally vest one year after issuance. To date, options granted under the 2011 Plan have vesting provisions ranging from one to three years in duration and expire ten years after issuance.

Compensation cost associated with employee stock options represented approximately $4.3 million and $1.5 million of the total share-based payment expense recorded for the three months ended June 30, 2021 and June 30, 2020, respectively. Compensation cost associated with employee stock options represented approximately $7.6 million and $2.9 million of the total share-based payment expense recorded for the six months ended June 30, 2021 and June 30, 2020, respectively. The Company estimates the fair value of stock options using a Black-Scholes valuation model, and the resulting fair value is recorded as compensation cost on a straight-line basis over the option vesting period. Key inputs and assumptions used to estimate the fair value of stock options include the grant price of the award, the expected option term, volatility of the Company’s stock, an appropriate risk-free rate, and the Company’s dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by employees who receive equity awards, and subsequent events are not indicative of the reasonableness of the original estimates of fair value made by the Company. The assumptions made for purposes of estimating fair value under the Black-Scholes model for the 698,500 and 174,649 options granted during the six months ended June 30, 2021 and 2020, respectively, were as follows:


	June 30,	June 30,
	2021	2020
Expected term of options (years)	5	6
Risk free interest rate	0.61% - 1.04%	0.45% - 1.37%
Volatility	72.46% - 73.69%	64.19% - 64.80%

There was 0 expected dividend yield for the employee stock options granted.

The Company has historically used the simplified method in determining its expected term of all its stock option grants in all periods presented. The simplified method was used because the Company did not believe historical exercise data provided a reasonable basis for the expected term of its grants, primarily as a result of the limited number of stock option exercises that have historically occurred. Due to the recent increase in exercise activity at the Company, beginning in the second quarter of 2021, the expected term is based on historical experience. The estimated stock price volatility was derived from the Company’s actual historic stock prices over the past five years, which represents the Company’s best estimate of expected volatility.

Overview

Part of our long-term plan includes Plug Power penetrating the on-road vehicle market and large-scale stationary market. Plug Power’s formation of a joint venture with Renault in Europe and the announced future joint venture with SK

Table of Contents

Group 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. For example, we expect our relationships with Brookfield and Apex to provide us access to low-cost renewable energy, which is critical to produce low-cost green hydrogen.

Our current products and services include:

GenDrive: GenDrive is our hydrogen fueled PEM fuel cell system providing power to material handling electric vehicles, including class 1, 2, 3 and 6 electric forklifts, Automated Guided Vehicles (“AGVs”) and ground support equipment;

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

ProGen: ProGen is our fuel cell stack and engine technology currently used globally in mobility and stationary fuel cell systems, and as engines in electric delivery vans. This includes the Plug “MEA”, a critical component of the fuel cell stack used in zero-emission fuel cell electric vehicle engines; and

We provide our products worldwide through our direct product sales force, and by leveraging relationships with “OEMs” and their dealer networks. Plug Power is targeting Asia and Europe for expansion in adoption. Europe has rolled out ambitious targets for the hydrogen economy and Plug Power is executing on its strategy to become one of the European leaders. This includes a targeted account strategy for material handling as well as securing strategic partnerships with European OEMs, energy companies, utility leaders and accelerating our electrolyzer business. We manufacture our commercially viable products in Latham, New York, Rochester, New York and Spokane, Washington and support liquid hydrogen generation and logistics in Charleston, Tennessee.

Recent Developments

COVID-19 Update

As a result of the COVID-19 pandemic outbreak in March 2020, state governments—including those in New York and Washington, where our manufacturing facilities are located—issued orders requiring businesses that do not conduct essential services to temporarily close their physical workplaces to employees and customers. As a result, we had

Table of Contents

put in place a number of protective measures in response to the COVID-19 outbreak, which included the canceling of all commercial air travel and all other non-critical travel, requesting that employees limit non-essential personal travel, eliminating all but essential third-party access to our facilities, enhancing our facilities’ janitorial and sanitary procedures, encouraging employees to work from home to the extent their job function enabled them to do so, encouraging the use of virtual employee meetings, and providing staggered shifts and social distancing measures for those employees associated with manufacturing and service operations. In May 2021, the Centers for Disease Control and Prevention (the “CDC”) revised guidance for fully vaccinated individuals regarding no longer needing to wear a mask indoors or practicing social distancing, which was subsequently adopted by the state of New York on May 19, 2021.

As a result, effective in June 2021 and in accordance with new CDC guidelines and where permitted by state law, employees who are fully vaccinated against COVID-19 and have been through Plug Power’s certification process may enter Plug Power facilities without a face covering. Individuals inside Plug Power facilities who do not wish to go through the certification process are required to wear proper face coverings and continue to maintain social distancing of 6 feet or greater. In states where the guidelines for face coverings is still government mandated, Plug Power will comply with the state and local jurisdictions and enforce face mask usage, as well as social distancing at our sites.

Plug Power will continue to provide enhanced janitorial and sanitary procedures, encourage employees to work from home to the extent their job function enables them to do so, and encourage the use of virtual employee meetings.

We cannot predict at this time the full extent to which COVID-19 will 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. Although as of the date hereof, we have not observed any material impacts to our supply of components, the situation is fluid. 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. Certain of our customers, such as Walmart, significantly increased their use of units and hydrogen fuel consumption as a result of COVID-19. In the three and six months ended June 30, 2021 and the twelve months ended December 31, 2020, our services and PPA margins were negatively impacted by incremental service costs associated with increased usage of units at some of our primary customer sites. In addition, future changes in applicable government orders or regulations, or changes in the interpretation of existing orders or regulations, could result in further disruptions to our business that may materially and adversely affect our financial condition and results of operations.

Strategic Activities

On June 3, 2021, our wholly-owned subsidiary, Plug Power France, created a joint venture with Renault named HyVia. HyVia plans to manufacture and sell FCELCVs and to supply hydrogen fuel and fueling stations to support the FCE-LCV market, in each case primarily in Europe. HyVia is owned 50% by Plug Power France and 50% by Renault. We include our share of the results of HyVia using the equity method based on our economic ownership interest and our ability to exercise significant influence over the operating and financial decisions of HyVia. We do not control this entity as our ownership is 50%, and as such HyVia is not included within our consolidated financial results for any period presented.

Charter Amendment

On July 30, 2021, our stockholders, upon recommendation of our Board of Directors, approved an amendment to our Amended and Restated Certificate of Incorporation (the “Charter Amendment”) to increase the number of authorized shares of common stock from 750,000,000 shares to 1,500,000,000 shares. The Charter Amendment became effective upon the filing of the Charter Amendment with the Secretary of the State of the State of Delaware on August 2, 2021.

Included within revenue was provision for common stock warrants of zero and $2.5 million for the three months ended June 30, 2021 and 2020, respectively. The main drivers for the increase in revenue were the increase in GenDrive units recognized as revenue, an increase in hydrogen installations and a decrease in the provision for common stock warrants. There were 3,666 GenDrive units recognized as revenue during the three months ended June 30, 2021, compared to 2,683 for the three months ended June 30, 2020. There was hydrogen infrastructure revenue associated with 16 hydrogen sites during the three months ended June 30, 2021, compared to four during the three months ended June 30, 2020.

Revenue from sales of fuel cell systems and related infrastructure for the six months ended June 30, 2021 increased $77.8 million, or 114.1%, to $146.1 million from $68.2 million for the six months ended June 30, 2020. Included within revenue was provision for common stock warrants of $27 thousand and $3.1 million for the three months ended June 30, 2021 and 2020, respectively. The main drivers for the increase in revenue were the increase in GenDrive units recognized as revenue, an increase in hydrogen installations and a decrease in the provision for common stock warrants. There were 4,974 GenDrive units recognized as revenue during the six months ended June 30, 2021, compared to 3,508 for the six months ended June 30, 2020.

Capped Call

Table of Contents

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

The net cost incurred in connection with the 3.75% Notes Capped Call was recorded as a reduction to additional paid-in capital in the unaudited interim condensed consolidated balance sheets.

5.5% Convertible Senior Notes

In May 2020, the Company used a portion of the net proceeds from the issuance of the 3.75% Convertible Senior Notes to finance the cash portion of the partial repurchase of the 5.5% Convertible Senior Notes, which consisted of a repurchase of approximately $66.3 million in aggregate principal amount of the 5.5% Convertible Senior Notes in privately-negotiated transactions for aggregate consideration of $128.9 million, consisting of approximately $90.2 million in cash and approximately 9.4 million shares of the Company’s common stock. The partial repurchase of the 5.5% Convertible Senior Notes resulted in a $13.2 million gain on early debt extinguishment. In the fourth quarter of 2020, $33.5 million of the remaining 5.5% Convertible Senior Notes converted into 14.6 million shares of common stock which resulted in a gain of approximately $4.5 million and was recorded on the unaudited interim condensed consolidated statement of operations on the gain (loss) on extinguishment of debt line.

Fair Value

These levels are:

●

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

●

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

The fair values of the Company’s investments are based upon prices provided by an independent pricing service. Management has assessed and concluded that these prices are reasonable and has not adjusted any prices received from the independent provider. 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. There were no transfers between Level 1, Level 2, or Level 3 during the six months ended June 30, 2021.

Off-Balance Sheet Arrangements

The Company does not have off-balance sheet arrangements that are likely to have a current or future significant effect on the Company’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

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 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 on-going basis, we evaluate our estimates and judgments, including those related to revenue recognition, bad debts, inventories, intangible assets, impairment of long-lived assets and PPA executory contract consideration, accrual for loss on extended maintenance contracts, operating and finance leases, product warranty reserves, 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 2020 10-K.

Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

On January 1, 2021, we early adopted ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) using the modified retrospective approach. Consequently, the Company’s 3.75% Convertible Senior Notes is now accounted for as a single liability measured at its amortized cost. This accounting change removed the impact of recognizing the equity component of the Company’s convertible notes at issuance and the subsequent accounting impact of additional interest expense from debt discount amortization. Future interest expense of the convertible notes will be lower as a result of adoption of this guidance and net loss per share will be computed using the if-converted method for convertible instruments. The cumulative effect of the accounting change upon adoption on January 1, 2021 increased the carrying amount of the 3.75% Convertible Senior Notes by $120.6 million, reduced accumulated deficit by $9.6 million and reduced additional paid-in capital by $130.2 million.

Recent Accounting Guidance Not Yet Effective

All issued but not yet effective accounting and reporting standards as of June 30, 2021 are either not applicable to the Company or are not expected to have a material impact on the Company.

There has been no material change from the information provided in the 2020 10-K “Item 7A: Quantitative and Qualitative Disclosures About Market Risk,” other than those described below.

Table of Contents

During the first six months of 2021, the Company purchased U.S. Treasury securities, corporate bonds, commercial paper, certificates of deposit, money market funds and municipal debt, in which the major components of market risk affecting us are credit risk and interest rate risk. We also purchased equity securities, in which the major component of market risk affecting us is equity risk.

Our exposure to changes in foreign currency rates is primarily related to sourcing inventory from foreign locations and operations of HyPulsion, S.A.S., our French subsidiary that develops and sells hydrogen fuel cell systems for the European material handling market. This practice can give rise to foreign exchange risk resulting from the varying cost of inventory to the receiving location. The Company reviews the level of foreign content as part of its ongoing evaluation of overall sourcing strategies and considers the exposure to be not significant. Our HyPulsion exposure presently is mitigated by low levels of operations and its sourcing is primarily intercompany in nature and denominated in U.S. dollars.

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 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 because of the material weakness in internal control over financial reporting described in Part II, Item 9A “Controls and Procedures” of our 2020 10-K. The material weakness has not been remediated as of June 30, 2021.

Material Weakness identified as of December 31, 2020

Management identified the following deficiency in internal control over financial reporting as of December 31, 2020: 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 activities in the following areas:

(a)

Presentation of operating expenses;

(b)

Accounting for lease-related transactions;

(c)

Identification and evaluation of impairment, accrual for loss contracts, certain expense accruals, and deemed dividends; and

(d)

Timely identification of adjustments to physical inventory in interim periods.

As reported on our 2020 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.

We will design and implement 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.

Table of Contents

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

We will augment 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.

We also intend to deploy new tools and tracking mechanisms to help enhance and maintain the appropriate documentation surrounding our classification of operating expenses.

We will report 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 weakness 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 they are operating effectively.

(b) Changes in internal control over financial reporting.

Exclusive of the steps taken in 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) occurred during the quarter ended June 30, 2021 that has materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1 — Legal Proceedings

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 March and May 2021, Company stockholders, individually and on behalf of all persons who purchased or otherwise acquired Plug securities between November 9, 2020 and March 16, 2021 (the “Class”), filed complaints in the U.S. District Court for the Southern District of New York and U.S. District Court for the Central District of California against the Company, Plug Chief Executive Officer Andrew Marsh, and Plug Chief Financial Officer Paul Middleton (together, the “Defendants”), captioned Dawn Beverly et al. v. Plug Power Inc. et al., Case No. 1:21-cv-02004 (S.D.N.Y.), Smolíček v. Plug Power Inc. et al., Case No. 2:21-cv-02402 (C.D. Cal.) and Tank v. Plug Power Inc. et al., Case No. 1:21-cv-03985 (S.D.N.Y.). The complaints include 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 Exchange Act (against Mr. Marsh and Mr. Middleton). The complaints allege that Defendants failed to disclose that the Company (i) “would be unable to timely file its 2020 annual report due to delays related to the review of classification of certain costs and the recoverability of the right to use assets with certain leases”; and (ii) “was reasonably likely to report material weaknesses

in its internal control over financial reporting[.]” The complaints allege that, a result, “positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis,” causing Class members losses and damages. The complaints seek compensatory damages “in an amount to be proven at trial, including 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 July 22, 2021, the U.S. District Court for the Southern District of New York consolidated the three cases and appointed a lead plaintiff. On July 28, 2021, Tank v. Plug Power, et. al., was voluntarily dismissed.

On March 31, 2021, Company stockholder Junwei Liu, derivatively and on behalf of nominal defendant Plug, filed a complaint in the U.S. District Court for the Southern District of New York against certain Company directors and officers (the “Derivative Defendants”), captioned Liu v. Marsh et al., Case No. 1:21-cv-02753 (S.D.N.Y.) (the “Liu Derivative Complaint”). The Liu Derivative Complaint alleges that, between November 9, 2020 and March 1, 2021, the Derivative Defendants “made, or caused the Company to make, materially false and misleading statements concerning Plug Power’s business, operations, and prospects” by “issu[ing] positive financial information and optimistic guidance, and made assurances that the Company’s internal controls were effective,” when, “[i]n reality, the Company’s internal controls suffered from material deficiencies that rendered them ineffective.” The Liu Derivative Complaint asserts claims for (1) breach of fiduciary duties, (2) unjust enrichment, (3) abuse of control, (4) gross mismanagement, (5) waste of corporate assets, and (6) contribution under Sections 10(b) and 21D of the Exchange Act (as to the named officer defendants). The Liu Derivative Complaint seeks a judgment “[d]eclaring that Plaintiff may maintain this action on behalf of Plug”; “[d]eclaring that the [Derivative] Defendants have breached and/or aided and abetted the breach of their fiduciary duties”; “awarding to Plug Power the damages sustained by it as a result of the violations” set forth in the Liu Derivative Complaint, “together with pre-judgment and post-judgment interest thereon”; “[d]irecting Plug Power and the [Derivative] Defendants to take all necessary actions to reform and improve Plug Power’s corporate governance and internal procedures to comply with applicable laws”; and “[a]warding Plaintiff the costs and disbursements of this action, including reasonable attorneys’ and experts’ fees, costs, and expenses”; and “[s]uch other and further relief as the [c]ourt may deem just and proper.”

On April 5, 2021, Company stockholders Elias Levy and Camerohn X. Withers, derivatively and on behalf of nominal defendant Plug, filed a complaint in the U.S. District Court for the Southern District of New York against the Derivative Defendants named in the Liu Derivative Complaint, captioned Levy et al. v. McNamee et al., Case No. 1:21-cv-02891 (S.D.N.Y.) (the “Levy Derivative Complaint”). The Levy Derivative Complaint alleges that, from November 9, 2020 to April 5, 2021, the Derivative Defendants “breached their duties of loyalty and good faith” by failing to disclose “(1) that the Company would be unable to timely file its 2020 annual report due to delays related to the review of classification of certain costs and the recoverability of the right to use assets with certain leases; (2) that the Company was reasonably likely to report material weaknesses in its internal control over financial reporting; and (3) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.” The Levy Derivative Complaint asserts claims for (1) breach of fiduciary duty (as to the named director defendants), (2) unjust enrichment (as to certain named director defendants), (3) waste of corporate assets (as to the named director defendants), and (4) violations of Sections 10(b) and 21D of the Exchange Act (as to the named officer defendants). The Levy Derivative Complaint seeks a judgment “declaring that Plaintiffs may maintain this action on behalf of the Company”; finding the Derivative Defendants “liable for breaching their fiduciary duties owed to the Company”; directing the Derivative Defendants “to take all necessary actions to reform and improve the Company’s corporate governance, risk management, and internal operating procedures to comply with applicable laws”; “awarding damages to the Company for the harm the Company suffered as a result of Defendants’ wrongful conduct”; “awarding damages to the Company for [the named officer Derivative Defendants’] violations of Sections 10(b) and 21D of the Exchange Act”; “awarding Plaintiffs the costs and disbursements of this action, including attorneys’, accountants’, and experts’ fees”; and “awarding such other and further relief as is just and equitable.” On April 27, 2021, the U.S. District Court for the Southern District of New York consolidated the Liu Derivative Complaint and the Levy Derivative Complaint under Case No. 1:21-cv-02753-ER (the “Consolidated Action”).

On May 13, 2021, Company stockholder Romario St. Clair, derivatively and on behalf of nominal defendant Plug, filed a complaint in the Supreme Court of the State of New York, County of New York against the Derivative Defendants named in the Liu Derivative Complaint, captioned St. Clair v. Plug Power Inc. et al., Index No. 653167/2021 (N.Y. Sup. Ct., N.Y. Cty.) (the “St. Clair Derivative Complaint”). The St. Clair Derivative Complaint alleges that, for

Table of Contents

approximately two years beginning on March 13, 2019, the Company “failed to disclose and misrepresented the following material, adverse facts, which the [Derivative] Defendants knew, consciously disregarded, or were reckless in not knowing,” including: “(a) that the Company was experiencing known but undisclosed material weaknesses in its internal controls over financial reporting; (b) the Company was overstating the carrying amount of certain right of use assets and finance obligations associated with leases; (c) the Company was understating its loss accrual on certain service contracts; (d) the Company would need to take impairment charges relating to certain long-lived assets; (e) the Company was improperly classifying research [and] development costs versus costs of goods sold; and (f) the Company would be unable to file its Annual Report for the 2020 fiscal year due to these errors.” The St. Clair Derivative Complaint asserts claims for (1) breach of fiduciary and (2) unjust enrichment. The St. Clair Derivative Complaint seeks a judgment “for the amount of damages sustained by the Company” as a result of the Derivative Defendants’ breaches of fiduciary duties and unjust enrichment; “[d]irecting Plug Power to take all necessary actions to reform and improve its corporate governance and internal procedures to comply with applicable laws”; for “equitable and/or injunctive relief as permitted by law, equity, and state statutory provisions”; “awarding to Plug Power restitution” and “ordering disgorgement of all profits, benefits, and other compensation obtained” by the Derivative Defendants; “awarding to plaintiff the costs and disbursements of the action, including reasonable attorneys’ fees, accountants’ and experts’ fees, costs, and expenses”; and “granting such other and further relief as the [c]ourt deems just and proper.”
