Table of Contents

$9 thousand ~~and $0~~ of income tax expense for the six months ended June 30, 2023 and 2022, ~~and 2021,~~ respectively. The tax benefit for the six months ended June 30, 2023 was due to foreign income taxes. 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~~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~~carryforward will not be realized. The Company recognizes accrued interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense.

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 0no transfers between Level 1, Level 2, or Level 3 for the three and six months ended June 30, ~~2022.~~2023.

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.~~Hyverse. During the three and six months ended June 30, ~~2022,~~2023, the Company contributed approximately $0$0.8 million and ~~$22.6~~$40.9 million, respectively, to HyVia, AccionaPlug ~~S.L.~~ and SK Plug ~~Hyverse Co., Ltd.~~Hyverse.

17. Operating and Finance Lease Liabilities

As of June 30, ~~2022,~~2023, the Company had operating leases, as lessee, primarily associated with sale/leaseback transactions that are partially secured by restricted cash and security deposits ~~and pledged escrows~~ (see also Note ~~1, “Nature of Operations”~~19, “Commitments and Contingencies”) as summarized below. These leases expire over the next one to nine years. Minimum rent payments under operating leases are recognized on a straight-line basis over the term of the lease.

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

The Company has finance leases associated with its property and equipment in Latham, New York and at fueling customer locations. The fair value of this finance obligation approximated the carrying value as of June 30, ~~2022.~~

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

Table of Contents

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, 2~~2023, two customers comprised ~~36.4%~~33.7% of the total accounts receivable balance. At December 31, ~~2021, 1~~2022, one customer comprised approximately ~~46.6%~~24.9% 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, 2023, 63.0% and 41.9% of total consolidated revenues were associated with two customers, respectively. For the three and six months ended June 30, 2022, 38.0% and 35.5% of total consolidated revenues were associated with 2two customers, respectively. ~~For~~

On May 30, 2023, HyVia entered into a government grant agreement with Bpifrance. As part of the ~~three~~agreement, our wholly-owned subsidiary, Plug Power France, was required to issue a guarantee to Bpifrance in the amount of €20 million through the end of January 2027. Plug Power France is liable to the extent of the guarantee for sums due to Bpifrance from HyVia under the agreement based on the difference between the total amount paid by Bpifrance and ~~six months ended~~the final amount certified by HyVia and Bpifrance. As part of the agreement, there are certain milestones that HyVia is required to meet, and the non-performance of these milestones or termination of this agreement could result in this guarantee being called upon. As of June 30, ~~2021, 81.3%~~2023, no payments related to this guarantee have been made by the Company, and ~~77.7%~~Plug Power France did not record a liability for this guarantee as the likelihood of ~~total consolidated revenues were associated~~the guarantee being called upon as of June 30, 2023 is remote.

Unconditional purchase obligations

The Company has entered into certain off–balance sheet commitments that require the future purchase of goods or services (“unconditional purchase obligations”). The Company’s unconditional purchase obligations primarily consist of supplier arrangements, take or pay contracts and service agreements. For certain vendors, the Company’s unconditional obligation to purchase a minimum quantity of raw materials at an agreed upon price is fixed and determinable; while certain other raw material costs will vary due to product forecasting and future economic conditions. Future payments under non-cancelable unconditional purchase obligations with ~~3 customers, respectively.~~a remaining term in excess of one year as of June 30, 2023, are as follows (in thousands):

20. Employee Benefit Plans

2011 and 2021 Stock Option and Incentive Plan

The Company has issued stock-based awards to employees and members of its Board of Directors (the “Board”) consisting of stock options and restricted stock and restricted stock unit awards. The Company accounts for all stock-based awards to employees and members of the Board as compensation costs in the consolidated financial statements based on their fair values measured as of the date of grant. These costs are recognized over the requisite service period. Stock-based compensation costs recognized, excluding the Company’s matching contributions of $3.0 million to the Plug Power Inc. 401(k) Savings & Retirement Plan and quarterly Board compensation, were ~~$42.6~~$36.9 million and ~~$11.1~~$42.6 million for the three months ended June 30, ~~2022~~2023 and June 30, ~~2021,~~2022, respectively. Stock-based compensation costs recognized, excluding the Company’s matching contributions of $6.0 million to the Plug Power Inc. 401(k) Savings & Retirement Plan and quarterly Board compensation, were ~~$83.5~~$77.0 million and ~~$19.6~~$83.5 million for the six months ended June 30, ~~2022~~2023 and June 30, ~~2021,~~2022, respectively. The methods and assumptions used in the determination of the fair value of stock-based awards are consistent with those described in our ~~2021~~2022 Form 10-K.

The components and classification of stock-based compensation expense, excluding the Company’s matching contributions to the Plug Power Inc. 401(k) Savings & Retirement Plan and quarterly Board compensation, were as follows (in thousands):

Compensation cost associated with service stock options represented approximately ~~$6.5~~$6.9 million and ~~$4.3~~$6.5 million of the total share-based payment expense recorded for the three months ended June 30, ~~2022~~2023 and ~~2021,~~2022, respectively. Compensation cost associated with service stock options represented approximately ~~$12.4~~$15.2 million and ~~$7.6~~$12.4 million of the total share-based payment expense recorded for the six months ended June 30, ~~2022~~2023 and ~~2021,~~2022, respectively. As of June 30, ~~2022,~~2023, there was approximately ~~$43.6~~$40.7 million of unrecognized compensation cost related to service stock option awards to be recognized over the weighted average remaining period of ~~1.96~~1.84 years.

Performance Stock Option Awards

In May 2023, the Compensation Committee approved the grant of performance stock options to the Company’s Chief Executive Officer and certain other executive officers. These performance stock options are subject to both performance based conditions, tied to the achievement of stock price hurdles, and time-based vesting; therefore, a Monte Carlo Simulation was utilized to determine the grant date fair value with the associated expense recognized over the requisite service period. Up to one third (1/3) the performance stock options will vest and become exercisable on each of the first three anniversaries of the grant date, provided that the volume weighted average price of the Company’s common stock during any 30 consecutive trading day period in the three year performance period following the grant date of the stock options (“VWAP”) equals or exceeds certain levels.

There will be no interpolation for the performance stock option granted on May 18, 2023 if the VWAP falls between any two stock price hurdles, unless in the event of a change in control. For the Chief Executive Officer and executive officers, 33.33% of the performance stock options will be deemed to have satisfied the performance-based condition and will be eligible to be exercised if the VWAP equals $9.84; an additional 33.33% of the options will be deemed to have satisfied the performance-based condition and will be eligible to be exercised if the VWAP equals $11.81; and the remaining 33.34% of the options will be deemed to have satisfied the performance-based condition and will be eligible to be exercised if the VWAP equals or exceeds $13.77.

Failure to achieve any of the stock price hurdles applicable to a performance stock option during the three-year performance period will result in the applicable options not becoming exercisable. The performance-based stock options have a maximum term of seven years from the grant date.

Key inputs and assumptions used to estimate the fair value of performance stock options include the grant price of the awards, the expected option term, VWAP hurdle rates, 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 following table presents key assumptions used to estimate the fair value of the performance stock option awards granted in 2023:


		Six Months Ended
		June 30, 2023
Remaining VWAP performance period (years)		3
Risk-free interest rate		3.60%
Expected volatility		75.00%
Closing stock price on grant date		$ 7.87

Recent Developments

Cybersecurity Update

In or around March 2023, an unauthorized actor accessed our computer network and executed a ransomware attack, resulting in the encryption of certain of our computer systems, including systems used to store proprietary and confidential data, and exfiltration of limited data sets. Upon detection, we took immediate steps to contain, assess and remediate the incident, including engaging outside legal counsel and external forensic investigators. Necessarily, the Company has incurred costs in addressing the incident, including related to investigation, containment, restoration, and remediation. As a result of the unauthorized access, the Company’s employees experienced interruption of access to the internal network, which created temporary disruption of certain internal operations and automated processes. As of the date of the filing for the Form 10-Q for the quarter ended March 31, 2023, the Company had restored the affected systems and throughout this restoration period the Company’s business remained fully operational with no material disruption. Based on information available to date, we do not believe the ransomware event has had a material impact on our business as of and for the six-month period ended June 30, 2023.

COVID-19 Update

~~Starting on January 3, 2022, all U.S. based employees, including temporary employees were required to either be vaccinated against~~

While we no longer enforce our prior COVID-19 ~~or be subject~~policies with respect to weekly COVID-19 testing, ~~in an effort to stop the spread of~~face coverings, or daily COVID-19 ~~and~~questionnaires, we continue to ~~protect~~monitor the COVID-19 pandemic and emerging variants and remain prepared to adjust our ~~workforce. As of February 28, 2022, we discontinued the weekly testing for unvaccinated employees~~policies and ~~removed the mask requirement for fully vaccinated employees. Our positive cases declined significantly;~~

~~and that, combined~~safety protocols in line 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.agencies. 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 are no longer ~~are~~ requiring staggered shifts in our manufacturing facilities and are offering hybrid work schedules to ~~those whose~~certain employees depending on business needs and 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.requirements.

~~We continue~~Inflation, Material Availability and Labor Shortages

Most components essential to ~~take proactive steps to limit the impact of these challenges and~~our business are ~~working closely with our~~generally available from multiple sources; however, we believe there are some component suppliers and ~~transportation~~manufacturing vendors, particularly those suppliers and vendors that supply materials in very limited supply worldwide or supply commodities that have high degree of volatility, whose loss to ~~ensure availability of products~~us or general unavailability could have a material adverse effect upon our business and ~~implement other cost savings initiatives.~~financial condition. Furthermore, global commodity pricing is very volatile and influenced by political events and worldwide economic trends, which may impact our sourcing strategies resulting in adverse impacts on our business and financial condition. We are mitigating these potential risks by introducing alternate system architectures that we expect will allow us to diversify our supply chain with multiple fuel cell, electrolyzer stack and air supply component vendors. 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~~We are also working closely with these vendors and other key suppliers on coordinated product introduction plans, product and sales forecasting, strategic inventories, and internal and external manufacturing schedules and levels; however, changes to our products designs, new product serviceability trends, or incorrect forecasting could present challenges to those strategies despite best efforts in leveraging supplier relationship and capabilities.

cost pressures from global energy prices and inflation have negatively impacted access to our key raw materials. Additionally, our regionally diverse supply chain could result in price shifts from one region to another region that may affect our costs and strategic initiatives. In cases where we have single sourced suppliers (typically due to new technology and products or worldwide shortages due to global demand), we work to engineer alternatives in our product design or develop new supply sources while covering short- and medium-term risks with supply contracts, building up inventory, and development partnerships. However, if we, or the industry or economy at large, were to experience a recession, then we may have a large stock of pre-purchased inventory that could be unused and aging for a period of time. We continue to take proactive steps through our supply chain team to limit the impact of suppliers challenges generally and we continue to work closely with our suppliers and transportation vendors to ensure 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~~implement other cost savings initiatives.

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,~~January 2023, the Company ~~may encounter difficulties~~entered into a strategic partnership with Johnson Matthey Hydrogen Technologies Limited, a subsidiary of Johnson Matthey PLC and a global leader in ~~obtaining certain raw materials or components necessary for production due~~sustainable technologies (“JM”), pursuant to ~~supply chain constraints and logistical challenges,~~ which may also negatively impact the pricing of materials and components sourced or used by the Company.

While~~ the Company ~~does not currently anticipate any significant, broad-based difficulties~~catalyst coated membrane for use in ~~obtaining raw materials or components necessary for~~the 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,~~of fuel cells as well as ~~increased prices~~catalysts and membranes for ~~freight and logistics, including air, sea and ground freight.

In addition, the Company ~~may experience supply shortages for raw materials or components~~and JM intend to develop their existing and new technology and commercial products and co-invest in a manufacturing facility 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.United States.

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

Results of Operations

Our primary sources of revenue are from sales of fuel cell systems, related infrastructure and equipment, services performed on fuel cell systems and related infrastructure, Power Purchase Agreements (PPAs), and fuel delivered to customers. A certain portion of our sales result from acquisitions in legacy markets, which we are working to transition to renewable solutions. Revenue from sales of fuel cell systems, related infrastructure and equipment represents sales of our GenDrive units, GenSure stationary backup power units, cryogenic stationary and ~~onroad~~on road storage, electrolyzers and hydrogen fueling infrastructure. Revenue from services performed on fuel cell systems and related infrastructure represents revenue earned on our service and maintenance contracts and sales of spare parts. Revenue from PPAs primarily represents payments received from customers who make monthly payments to access the Company’s GenKey solution. Revenue associated with fuel delivered to customers represents the sale of hydrogen to customers that has been purchased by the Company from a third party or generated on site.

~~Based on historical experience,~~Provision for Common Stock Warrants

On August 24, 2022, the Company ~~experiences seasonality~~and Amazon entered into the 2022 Transaction Agreement, under which the Company concurrently issued to Amazon.com NV Investment Holdings LLC, a wholly owned subsidiary of Amazon, the Amazon Warrant, to acquire the Amazon Warrant Shares, subject to certain vesting events described below. The Company and Amazon entered into the 2022 Transaction Agreement in connection with ~~respect~~a concurrent commercial arrangement under which Amazon agreed to ~~its~~purchase hydrogen fuel from the Company through August 24, 2029.

In 2017, in separate transactions, the Company issued to each of Amazon.com NV Investment Holdings LLC and Walmart warrants to purchase shares of the Company’s common stock. The Company recorded a portion of the estimated fair value of the warrants as a reduction of revenue ~~with more~~based upon the projected number of shares of common stock expected to vest under the warrants, the proportion of purchases by Amazon, Walmart and their affiliates within the period relative to the aggregate purchase levels required for vesting of the respective warrants, and the then-current fair value of the warrants. For the third tranche of the shares under Walmart’s warrant, the exercise price will be determined once the second tranche vests. For the third tranche of the Amazon Warrant Shares, see below for the exercise price and measurement dates used.

The Company and Amazon entered into the 2022 Transaction Agreement in connection with a concurrent commercial arrangement under which Amazon agreed to purchase hydrogen fuel from the Company through August 24, 2029.

Upon the consummation of certain change of control transactions (as defined in the applicable warrant) prior to the vesting of at least 60% of the aggregate Amazon Warrant Shares, the Amazon Warrant will automatically vest and become exercisable with respect to an additional number of Amazon Warrant Shares such that 60% of the aggregate Amazon Warrant Shares shall have vested. If a change of control transaction is consummated after the vesting of at least 60% of the aggregate Amazon Warrant Shares, then no acceleration of vesting will occur with respect to any of the unvested Amazon Warrant Shares as a result of the transaction. The exercise price and the Amazon Warrant Shares issuable upon exercise of the Amazon Warrant are subject to customary antidilution adjustments.

Upon issuance, 1,000,000 of the Amazon Warrant Shares issued pursuant to the 2022 Transaction Agreement vested. The warrant fair value associated with the vested shares of $20.4 million was capitalized to contract assets in our unaudited interim condensed consolidated financial statements based on the grant date fair value and is subsequently amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement.

Because the exercise price has yet to be determined, the fair value of tranche 4 will be remeasured at each reporting period end and amortized ratably as a reduction to revenue based on the Company’s estimate of revenue over the term of the agreement. 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, 2023 and 2022 was $1.5 and $0.1 million, respectively.

As part of the agreement, our wholly-owned subsidiary, Plug Power France, was required to issue a guarantee to Bpifrance in the amount of €20 million through the end of January 2027. Plug Power France is liable to the extent of the guarantee for sums due to Bpifrance from HyVia under the agreement based on the difference between the total amount paid by Bpifrance and the final amount certified by HyVia and Bpifrance. As part of the agreement, there are certain milestones that HyVia is required to meet, and the non-performance of these milestones or termination of this agreement could result in this guarantee being called upon. As of June 30, 2023, no payments related to this guarantee have been made by the Company, and Plug Power France did not record a liability for this guarantee as the likelihood of the guarantee being called upon as of June 30, 2023 is remote.

Unconditional purchase obligations

The Company has entered into certain off–balance sheet commitments that require the future purchase of goods or services (“unconditional purchase obligations”). The Company’s unconditional purchase obligations primarily consist of supplier arrangements, take or pay contracts and service agreements. For certain vendors, the Company’s unconditional obligation to purchase a minimum quantity of raw materials at an agreed upon price is fixed and determinable; while certain other raw material costs will vary due to product forecasting and future economic conditions. Future payments under non-cancelable unconditional purchase obligations with a remaining term in excess of one year as of June 30, 2023, are as follows (in thousands):

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~~on-going 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.~~warrants. 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~~2022 Form 10-K.

Evaluation of Disclosure 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, isare 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.~~June 30, 2023. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of June 30, 2023, 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~~2022 Form 10-K. The material weaknesses have not been remediated as of June 30, ~~2022.~~2023.

~~Material Weakness~~Changes in Internal Control over Financial Reporting

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 thereThere were no changes ~~to previously issued financial results as a result of~~during 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 weaknessesquarter ended June 30, 2023 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~~our internal control over financial reporting.

The Inflation Reduction Act of 2022 (“IRA”) contains tax credits and incentives for clean hydrogen, fuel cells, and other clean energy technologies. The Company’s ability to benefit from these incentives, in particular the Section 45V Credit for the Production of Clean Hydrogen, is not guaranteed and is dependent upon the federal government’s forthcoming and ongoing implementation, guidance, regulations, and/or rulemakings that have been the subject of substantial public interest and debate.

In August 2022, President Biden signed the IRA into law. The IRA contains hundreds of billions in credits and incentives for the development of renewable energy, clean hydrogen, clean fuels, electric vehicles and supporting infrastructure and carbon capture and sequestration, among other provisions. The IRA contains numerous credits and tax incentives that may be relevant to us, including: (i) an extension and amendment of the Section 48 Investment Tax Credit for Qualified Fuel Cell Properties, which provides a tax credit based on capital investment in a variety of renewable and conventional energy technologies to incentive investment in new energy resources and more efficient use of fuel, including fuel cell technology; (ii) a new Section 48 Investment Tax Credit for Energy Storage Technologies, which expands the applicability of the investment tax credit to include standalone energy storage projects, among other things; (iii) a new Section 45V Credit for the Production of Clean Hydrogen, which provides a production tax credit of up to $3 per kg of qualified clean hydrogen over a 10-year credit period for the production of qualified clean hydrogen at a qualified facility in the United States; (iv) an amended Section 48C Qualified Advanced Energy Project Credit, which provides an investment tax credit through a competitive application process administered through the Department of Energy equal to 6% or 30% of the investment with respect to advanced energy projects; (v) a new Section 45X Advanced Manufacturing Production Credit, which provides varying credit amounts with respect to the production of certain components manufactured in the United States; and (vi) a new Section 48E Clean Electricity Investment Tax Credit, which provides a tax credit for investment in facilities that generate clean electricity, among other provisions.

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

generation projects. Specifically, guidance, rules, or regulations limiting a hydrogen production facility’s use of renewable energy credits, environmental attributes, and grid electricity could limit the Company’s ability to benefit from the Section 45V Credit for the Production of Clean Hydrogen. As the Company has endeavored numerous hydrogen generation projects prior to the promulgation of Section 45V’s guidance, there is no guarantee that the Company’s projects will comply with the final eligibility requirements of Section 45V. As a result, the final interpretation and implementation of the provisions in the IRA could have a material adverse impact on the Company – both in our ability to leverage Section 45V and compete with other hydrogen generation projects more closely aligned with potential IRA requirements. Furthermore, future legislative enactments or administrative actions could limit, amend, repeal, or terminate IRA policies or other incentives that the Company currently hopes to leverage. Any reduction, elimination, or discriminatory application or expiration of the IRA may result in the Company’s diminished economic competitiveness and could materially and adversely affect the Company’s future operating results and liquidity.
