Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and right-of-use (&#8220;ROU&#8221;) assets, and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p></ix:nonNumeric></ix:nonNumeric></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">9</p></div></div>

As most of the Company&#8217;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#8217;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#8217;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities, to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense.

(&#8220;POSCO Energy&#8221;) to develop and grow the South Korean and Asian markets for our products and services. We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February&#160;7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February&#160;7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October&#160;27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October&#160;31, 2012 (and the amendments thereto), which are collectively referred to herein as the &#8220;License Agreements.&#8221;&#160;The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#8220;KFC&#8221;), without the Company&#8217;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#8217;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#8217;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#8217;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#8217;s failure to pay royalties required to be paid in connection with certain module exchanges.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore alleging certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and seeking combined damages of approximately $<ix:nonFraction unitRef="Unit_Standard_USD_vloxz5lR7EKmOTOF1zSjFg" contextRef="Duration_4_27_2020_To_4_27_2020_srt_MajorCustomersAxis_fcel_PoscoEnergyMember_4ovgBhTrp0WL-DP9mAjQlQ" decimals="-5" format="ixt:numdotdecimal" name="us-gaap:LossContingencyDamagesSoughtValue" scale="6" id="Narr_9aSSvSiyXk6s2YBzDHYSAA">3.3</ix:nonFraction> million.

POSCO Energy alleges that it is seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#8217;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith.

The preparation of financial statements and related disclosures requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities, as well as management&#8217;s assessment of the Company&#8217;s ability to meet its obligations as they come due over the next twelve&#160;months. Actual results could differ from those estimates. Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and ROU assets, and contingencies, and in management&#8217;s assessment of the Company&#8217;s ability to meet its obligations as they come due over the next twelve&#160;months. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates. The following discussion should be read in conjunction with information included in our Annual Report on Form&#160;10-K for the fiscal&#160;year ended October&#160;31, 2020 filed with the Securities and Exchange Commission (&#8220;SEC&#8221;).

The Company took these actions to secure the safety of the Company&#8217;s employees, our corporate community as a whole, and the communities in which our team members live, and to adhere to Centers for Disease Control (CDC) recommendations of social distancing and limited public exposure in connection with the COVID-19 pandemic.

We did not implement any furlough, layoff or shared work program during such time. The Company resumed manufacturing in June&#160;2020 and the Torrington, Connecticut manufacturing facility employees returned to work.

decreased $6.3 million to $0.7 million from $7.0&#160;million for the three&#160;months ended April&#160;30, 2020. The service and license revenues for the three&#160;months ended April&#160;30, 2021 include revenues recorded for routine maintenance activities offset by performance guarantees recorded. The decline in revenue for the three months ended April 30, 2021 is primarily due to the fact that there were no new module exchanges during the quarter (while new module exchanges generated approximately $5.5 million of revenue in the prior year quarter) combined with cost estimate adjustments related to changes in the expected timing of future module exchanges (which reduced revenue recognition in the quarter by approximately $0.8 million).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"> <span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Cost of service agreements and license revenues decreased $3.1 million to $2.9 million for the three&#160;months ended April&#160;30, 2021 from $6.0 million for the three&#160;months ended April&#160;30, 2020, resulting, in part, from the fact that there were two new module exchanges in the three&#160;months ended April&#160;30, 2020 compared to two used module exchanges in the three&#160;months ended April&#160;30, 2021. Also cost of sales recorded for planned maintenance and adjustments to the loss accrual to account for changes in the expected timing of future module exchanges were higher than in the three months ended April 30, 2020 due to continued investment in the service fleet in order to improve performance. Cost of service agreements includes maintenance and operating costs and module exchanges.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Overall gross loss from service agreements and license revenues was $2.2 million for the three&#160;months ended April&#160;30, 2021, which represents a decrease of $3.2 million from a gross profit of $1.0 million for the three&#160;months ended April&#160;30, 2020. The overall gross margin&#160;was (334.4)% for the three&#160;months ended April&#160;30, 2021 compared to a gross margin of 14.4% in the comparable prior&#160;year period. Gross margin decreased during the three&#160;months ended April&#160;30, 2021 primarily due to fewer new module exchanges compared to the three months ended April 30, 2020, additional performance guarantees recorded and adjustments to the loss accrual to account for changes in the expected timing of future module exchanges based on the Company&#8217;s current service schedule in order to

Generation revenues for the three&#160;months ended April&#160;30, 2021 and 2020 reflect revenue from electricity generated under our power purchase agreements (&#8220;PPAs&#8221;) as well as sales of renewable energy credits. The increase in generation revenues in the three months ended April 30, 2021 is primarily due to higher operating output of the generation fleet portfolio (which resulted in an increase in generation revenues of approximately $0.8 million) and sales of renewable energy credits (which also resulted in an increase in generation revenues of approximately $0.8 million). </p><a id="_Hlk73534402"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Cost of generation revenues totaled $9.4 million in the three&#160;months ended April&#160;30, 2021. The increase from the comparable prior&#160;year period was primarily due to an increase in maintenance activities undertaken in the three months ended April 30, 2021 in order to improve operating output. Cost of generation revenues included depreciation and amortization of approximately $3.6 million and $3.2 million for the three&#160;months ended April&#160;30, 2021 and 2020, respectively. </p><p

from $7.3 million for the three&#160;months ended April&#160;30, 2020. Compared to the three&#160;months ended April&#160;30, 2020, Advanced Technologies contract revenues recognized under the Joint Development Agreement entered into with ExxonMobil&#160;Research and&#160;Engineering Company (&#8220;EMRE&#8221;)&#160;on November 5, 2019&#160;(the &#8220;EMRE Joint Development Agreement&#8221;) were approximately $0.4 million higher during the three&#160;months ended April&#160;30, 2021, reflecting continued performance under our Joint Development Agreement with EMRE on fuel cell carbon capture solutions during the quarter. However, the increased revenues under the EMRE Joint Development Agreement were offset by the $0.6 million less revenue recognized under government contracts during the three&#160;months ended April&#160;30, 2021 than during the three&#160;months ended April&#160;30, 2020. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Cost of Advanced Technologies contract revenues increased $0.3 million to $4.5&#160;million for the three&#160;months ended April&#160;30, 2021, compared to $4.2 million for the same period in the prior&#160;year. Advanced Technologies contracts for the three&#160;months ended April&#160;30, 2021 generated a gross margin of $2.6 million compared to a gross margin of $3.1 million for the three&#160;months ended April&#160;30, 2020. The decrease in Advanced Technologies contract gross margin is primarily related to the mix of government contracts which resulted in a higher cost share incurred by the Company on such contracts in the three&#160;months ended April&#160;30, 2021 compared to the three&#160;months ended April&#160;30, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Administrative and selling expenses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Administrative and selling expenses were $9.7 million and $7.2&#160;million for the three&#160;months ended April&#160;30, 2021 and 2020, respectively. The three&#160;months ended April&#160;30, 2021 included additional expense for share-based compensation of $0.8 million due to the grants made in August&#160;2020 and November&#160;2020 under our new Long Term Incentive Plans (the </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">30</p></div></div>

The increase relates to an increase in spending on the Company&#8217;s hydrogen commercialization initiatives compared to the comparable prior&#160;year period, which prior&#160;year period was also impacted by restructuring initiatives implemented in 2019 as resources were instead allocated to funded Advanced Technologies projects.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Loss from operations</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Loss from operations for the three&#160;months ended April&#160;30, 2021 was $17.4 million compared to $8.1 million for the three&#160;months ended April&#160;30, 2020. This increase was due to higher gross loss of $4.8 million and higher operating expenses of $4.3 million for the three months ended April 30, 2021. As discussed above, impacting gross loss for the quarter were (i) lower service gross margin due to the fact that no new module exchanges took place during the quarter and due to adjustments to the loss accrual reserves to account for changes in the expected timing of future module exchanges in the second quarter of 2021, (ii) lower generation gross margin related to higher costs for plant maintenance as we continue to invest in efforts to improve fleet performance, and (iii) lower advanced technologies gross margin given the mix of activities in the quarter. These impacts were partially offset by lower manufacturing variances as a result of the increase in the annualized factory production rate.<span style="font-family:'Arial','Helvetica','sans-serif';font-size:11pt;"> </span>Operating expenses were higher in the period as (a) administrative and selling expenses for the three&#160;months ended April&#160;30, 2021 were higher and included additional share-based compensation expense under the LTI Plans and an increase in compensation expense and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting and (b) research and development expenses were higher due to an increase in spending on the Company&#8217;s hydrogen commercialization initiatives compared to the comparable prior&#160;year period.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"><b style="font-weight:bold;">Interest expense</b></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Interest expense for the three&#160;months ended April&#160;30, 2021 and 2020 was $1.6 million and $3.6 million, respectively.

The decrease in interest expense for the three&#160;months ended April&#160;30, 2021 is primarily due to the repayment of the $80.0 million principal balance outstanding under the Orion Credit Agreement (as defined below), which was fully repaid in December&#160;2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Change in fair value of common stock warrant liability</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The $3.4 million expense for the three&#160;months ended April&#160;30, 2020 represents an adjustment to the estimated fair value of the Orion Warrants (as defined below) still outstanding as of April 30, 2020. &#160;The expense was primarily a result of an increase in the price of the Company&#8217;s common stock during the quarter ended April 30, 2020.

For the three-month periods ended April&#160;30, 2021 and 2020, net loss attributable to common stockholders was $19.7 million and $15.6 million, respectively, and loss per common share was $0.06 and $0.07, respectively. The increase in the net loss attributable to common stockholders for the three&#160;months ended April&#160;30, 2021 is primarily due to incurring (i)&#160;a higher gross loss for the current year period compared to the corresponding period in fiscal&#160;year 2020, and (ii)&#160;higher operating expenses for the period including additional share-based compensation expenses under the LTI Plans. These amounts were offset by lower interest expense as a result of the repayment of the Orion Facility (as defined below) and the fact that there was no charge for the change in fair value of common stock warrant liability during the three months ended April 30, 2021. The lower loss per common share for the three&#160;months ended April&#160;30, 2021 as compared to the three&#160;months ended April&#160;30, 2020 is due to the higher weighted average shares

April&#160;30, 2021 to $4.3 million, compared to $4.9 million in the same period in the prior&#160;year. Both periods were impacted by the under-absorption of fixed overhead costs due to low production volumes. Manufacturing variances, primarily related to low production volumes and unabsorbed overhead costs, totaled approximately $3.4 million for the six&#160;months ended April&#160;30, 2021 compared to approximately $4.4 million for the six&#160;months ended April&#160;30, 2020.

As of April&#160;30, 2021 and April&#160;30, 2020, there was no product sales backlog. The production rate during the six months ended April 30, 2020 was impacted by the factory shutdown in response to the COVID-19 pandemic.</p><p style="font-family:'Times New

The decline in service and license revenues for the six&#160;months ended April&#160;30, 2021 is primarily due to fewer new module exchanges, cost estimate adjustments related to changes in the expected timing of future module exchanges which impacted revenue recognition and the fact that the six&#160;months ended April&#160;30, 2020 includes license revenues of $4.0 million associated with the EMRE Joint Development Agreement, while the six months ended April 30, 2021 does not include comparable license revenues. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Cost of service and license revenues increased $0.4 million to $8.0 million for the six&#160;months ended April&#160;30, 2021 from $7.6 million for the six&#160;months ended April&#160;30, 2020.

renewable energy credits. Generation revenues for the six&#160;months ended April&#160;30, 2021 and 2020 reflect revenue from electricity generated under our PPAs. Generation revenues for the six months ended April 30, 2021 also reflect the sale of renewable energy credits. The increase in generation revenues in the six months ended April 30, 2021 is primarily due to the improved operating output of the generation fleet portfolio and sales of renewable energy credits. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Cost of generation revenues totaled $16.5 million in the six&#160;months ended April&#160;30, 2021, which represents an increase from the comparable prior&#160;year period primarily due to increases in plant maintenance costs in 2021 in order to improve operating output and an increase depreciation and amortization expense related to a higher installed base of operating assets for the 2021 period compared to the prior year period. Cost of generation revenues included depreciation and amortization of approximately $8.0 million and $6.4 million for the six&#160;months ended April&#160;30, 2021 and 2020, respectively, and the

million for the six&#160;months ended April&#160;30, 2020. Compared to the six&#160;months ended April&#160;30, 2020, Advanced Technologies contract revenues recognized under the EMRE Joint Development Agreement were approximately $0.7 million higher during the six&#160;months ended April&#160;30, 2021, reflecting continued performance under our Joint Development Agreement with EMRE on fuel cell carbon capture solutions during the quarter. However, the increased revenues under the EMRE Joint Development Agreement were offset by the $1.0 million less revenue recognized under government contracts during the six&#160;months ended April&#160;30, 2021 than during the six&#160;months ended April&#160;30, 2020. Cost of Advanced Technologies contract revenues increased $0.4 million to $8.4&#160;million for the six&#160;months ended April&#160;30, 2021, compared </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">34</p></div></div>

Advanced Technologies contracts for the six&#160;months ended April&#160;30, 2021 generated a gross margin of $3.8 million compared to a gross margin of $4.5 million for the six&#160;months ended April&#160;30, 2020. The decrease in Advanced Technologies contract gross margin is related to the mix of government contracts which resulted in a higher cost share incurred by the Company on such contracts in the six&#160;months ended April&#160;30, 2021 compared to the six&#160;months ended April&#160;30, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Administrative and selling expenses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Administrative and selling expenses were $18.6 million and $12.4&#160;million for the six&#160;months ended April&#160;30, 2021 and 2020, respectively. The six&#160;months ended April&#160;30, 2021 included additional expense for shared-based compensation of $1.7 million due to the grants made in August&#160;2020 and November&#160;2020 under our new LTI Plans (refer to Note&#160;17. &#8220;Benefit Plans&#8221; to the Consolidated Financial Statements for more information on the November&#160;2020 grants), an increase in the value of a deferred director compensation liability due to an increase in the Company&#8217;s share price and increased compensation expense and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting. The comparable prior&#160;year period included a legal settlement of $2.2 million which was recorded as an offset to administrative and selling expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Research and development expenses</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Research and development expenses increased to $4.8 million for the six&#160;months ended April&#160;30, 2021 compared to $2.3 million for the six&#160;months ended April&#160;30, 2020. The increase relates to an increase in spending on the Company&#8217;s hydrogen commercialization initiatives compared to the comparable prior&#160;year period, which prior&#160;year period was also impacted by restructuring initiatives implemented in 2019 as resources were instead allocated to funded Advanced Technologies projects. During the six months ended April&#160;30, 2021, the Company successfully commenced operation and testing of a prototype solid oxide electrolysis hydrogen platform in Danbury, Connecticut.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Loss from operations</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Loss from operations for the six&#160;months ended April&#160;30, 2021 was $31.8 million compared to $11.3 million for the six&#160;months ended April&#160;30, 2020. This increase was due to a higher gross loss of $11.8 million and higher operating expenses of $8.7 million for the three months ended April 30, 2021. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">As discussed above, impacting gross loss for the six month period ended April 30, 2021 were (i) lower service gross margin due to residual value charges for certain plants which had reached the end of their service terms, fewer new module exchanges and an increase in performance guarantees, whereas gross margin for the six&#160;months ended April&#160;30, 2020 included license revenues associated with the EMRE Joint Development Agreement which resulted in positive margins, (ii) lower generation revenues gross margin primarily related to higher plant maintenance costs and depreciation expense and (iii) lower advanced technologies gross margin related to the mix of activities under government contracts during the period. These impacts were partially offset by lower manufacturing variances as a result of the increase in the annualized factory production rate.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Operating expenses were higher in the period as administrative and selling expenses and research and development expenses both increased for the six&#160;months ended April&#160;30, 2021. Administrative and selling expenses included additional share-based compensation expense under the LTI Plans,<span style="background-color:#ffffff;font-size:11pt;"> </span>an increase in the value of a deferred director compensation liability due to an increase in the Company&#8217;s share price, and an increase in compensation expense and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting. In addition, administrative and selling expenses for the six months ended April 30, 2020 included a $2.2 million legal settlement that offset administrative and selling expenses and there was no comparable gain for the six months ended April 30, 2021. Research and development expenses were higher due to an increase in spending on the Company&#8217;s hydrogen commercialization initiatives compared to the comparable prior&#160;year period. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-size:12pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Interest expense</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Interest expense for the six&#160;months ended April&#160;30, 2021 and 2020 was $4.1 million and $6.9 million, respectively.

This strategy requires liquidity and the Company expects to continue to have increasing liquidity requirements as project sizes increase and more projects are added to backlog. We may commence building project assets upon the award of a project or execution of a multi-year PPA with an end-user that has a strong credit profile. Project development and construction cycles, which span the time between securing a PPA and commercial operation of the platform, vary substantially and can take&#160;years. As a result of these project cycles and strategic decisions to finance the construction of certain projects, we may need to make significant up-front investments of resources in advance of the receipt of any cash from the sale or long-term financing of such projects. To make these up-front investments, we may use our working capital, seek to raise funds through the sale of equity or debt securities, or seek other financing arrangements. Delays in construction progress and completing current projects in process within budget, or in completing financing or the sale of our projects may impact our liquidity in a material way.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Our operating portfolio (32.6 MW as of April&#160;30, 2021) contributes higher long-term cash flows to the Company than if these projects had been sold. These projects currently generate approximately $19.9 million per&#160;year in annual revenue, but this amount may fluctuate from&#160;year to&#160;year depending on platform output, operational performance and management and site conditions. The Company plans to continue to grow this portfolio while also selling projects to investors. As of April&#160;30, 2021, the Company had projects representing an additional 43.5 MW in various stages of development and construction, which projects are expected to generate operating cash flows in future periods, if completed. Retaining long-term cash flow positive projects, combined with our service fleet, is expected to result in reduced reliance on new project sales to achieve cash flow positive operations, however, operations and performance issues could impact results. We have worked with and are continuing to work with lenders and financial institutions to secure construction financing, long-term debt, tax equity and sale-leasebacks for our project asset portfolio, but there can be no assurance that such financing can be attained, or that, if attained, it will be retained and sufficient.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">As of April&#160;30, 2021, net debt outstanding related to project assets was $68.9 million. Future required payments totaled $42.3 million as of April&#160;30, 2021.

Accordingly, on May&#160;16, 2019, an interest rate swap agreement (the &#8220;Swap Agreement&#8221;) was entered into with Fifth Third Bank in connection with the BFC Credit Agreement for the term of the loan. The net interest rate across the BFC Credit Agreement and the swap transaction results in a fixed rate of 5.09%. The interest rate swap is adjusted to fair value on a quarterly basis. The estimated fair value is based on Level 2 inputs including primarily the forward LIBOR curve available to swap dealers. The valuation methodology involves comparison of (i)&#160;the sum of the present value of all&#160;monthly variable rate payments based on a reset rate using the forward LIBOR curve and (ii)&#160;the sum of the present value of all&#160;monthly fixed rate payments on the notional amount, which is equivalent to the outstanding principal amount of the loan.

BFC is also required to maintain excess cash flow reserve accounts at each of Liberty Bank and Fifth Third Bank. Excess cash flow consists of cash generated by BFC from the Bridgeport Fuel Cell Project after payment of all expenses (including after payment of intercompany service fees to the Company), debt service to Liberty Bank and Fifth Third Bank, the funding of all required reserves, and payments to Connecticut Green Bank for the subordinated facility. BFC is also required to maintain a debt service coverage ratio of not less than 1.20, measured for the trailing&#160;year based on fiscal quarters beginning with the quarter ended July&#160;31, 2020. The Company has certain quarterly and annual financial reporting requirements under the BFC Credit Agreement. The annual financial statements to be provided pursuant to such requirements are to be audited and accompanied by a report of an independent certified public accountant, which report shall not include a &#8220;going concern&#8221; matter of emphasis or any qualification as to the scope of such audit.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">State of Connecticut Loan</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In October&#160;2015, the Company closed on a definitive Assistance Agreement with the State of Connecticut (the &#8220;Assistance Agreement&#8221;) and received a disbursement of $10.0 million, which was used for the first phase of the expansion of the Company&#8217;s Torrington, Connecticut manufacturing facility. In conjunction with this financing, the Company entered into a $10.0 million promissory note and related security agreements securing the loan with equipment liens and a mortgage on its Danbury, Connecticut location. Interest accrues at a fixed interest rate of 2.0%, and the loan is repayable over 15&#160;years from the date of the first advance, which occurred in October&#160;of 2015. Principal payments were deferred for four&#160;years from disbursement and began on December&#160;1, 2019. Under the Assistance Agreement, the Company was eligible for up to $5.0 million in loan forgiveness if the Company created 165 full-time positions and retained 538 full-time positions for two consecutive&#160;years (the &#8220;Employment Obligation&#8221;) as measured on October&#160;28, 2017 (the &#8220;Target Date&#8221;). The Assistance Agreement was subsequently amended in April&#160;2017 to extend the Target Date by two&#160;years to October&#160;28, 2019.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">In January&#160;2019, the Company and the State of Connecticut entered into a Second Amendment to the Assistance Agreement (the &#8220;Second Amendment&#8221;). The Second Amendment extended the Target Date to October&#160;31, 2022 and amended the Employment Obligation to require the Company to continuously maintain a minimum of 538 full-time positions for 24 consecutive&#160;months. If the Company meets the Employment Obligation, as modified by the Second Amendment, and creates an additional 91 full-time positions, the Company may receive a credit in the amount of $2.0 million to be applied against the outstanding balance of the loan. However, based on the Company&#8217;s current headcount and plans for fiscal&#160;year 2021 and beyond, it will not meet this requirement or receive this credit. A job audit will be performed within 90&#160;days of the Target Date. If the Company does not meet the Employment Obligation, then an accelerated payment penalty will be assessed at a rate of $18,587.36 multiplied by the number of employees below the number of employees required by the Employment Obligation. Such penalty is immediately payable and will be applied </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">47</p></div></div>

These deferred payments will be added at the end of the loan, thus extending out the maturity date by three&#160;months.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Restricted Cash</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We have pledged approximately $32.1 million of our cash and cash equivalents as performance security and for letters of credit for certain banking requirements and contracts. As of April&#160;30, 2021, outstanding letters of credit totaled $6.5 million. These expire on various dates through August&#160;2028. Under the terms of certain contracts, we will provide performance security for future contractual obligations. The restricted cash balance as of April&#160;30, 2021 also included $15.0 million primarily to support obligations under the power purchase and service agreements related to the PNC sale-leaseback transactions and $11.4 million relating to future obligations associated with the Bridgeport Fuel Cell Project. Refer to Note&#160;15. &#8220;Restricted Cash&#8221; for a detailed discussion of the Company&#8217;s restricted cash balance.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Power purchase agreements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Under the terms of our PPAs, customers agree to purchase power from our fuel cell power plants at negotiated rates. Electricity rates are generally a function of the customers&#8217; current and estimated future electricity pricing available from the grid. We are responsible for all operating costs necessary to maintain, monitor and repair our fuel cell power plants. Under certain agreements, we are also responsible for procuring fuel, generally natural gas or biogas, to run our fuel cell power platforms. In addition, under certain agreements, we are required to produce minimum amounts of power under our PPAs and we have the right to terminate PPAs by giving written notice to the customer, subject to certain exit costs. As of April&#160;30, 2021, our operating portfolio was 32.6 MW.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Service and warranty agreements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We warranty our products for a specific period of time against manufacturing or performance defects. Our standard U.S. warranty period is generally 15&#160;months after shipment or 12&#160;months after acceptance of the product. In addition to the standard product warranty, we have contracted with certain customers to provide services to ensure the power plants meet minimum operating levels for terms of up to 20&#160;years. Pricing for service contracts is based upon estimates of future costs, which could be materially different from actual expenses. Refer to &#8220;Critical Accounting Policies and Estimates&#8221; for additional details.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Advanced Technologies contracts</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We have contracted with various government agencies and certain companies from private industry to conduct research and development as either a prime contractor or sub-contractor under multi-year, cost-reimbursement and/or cost-share type contracts or cooperative agreements.&#160;Cost-share terms require that participating contractors share the total cost of the project based on an agreed upon ratio.&#160;In many cases, we are reimbursed only a portion of the costs incurred or to be incurred on the contract. While government research and development contracts may extend for many&#160;years, funding is often provided incrementally on a&#160;year-by-year basis if contract terms are met and Congress authorizes the funds. As of April&#160;30, 2021, Advanced Technologies contract backlog totaled $45.0 million, of which $28.3 million is non-U.S. Government-funded, $16.5 million is U.S. Government-funded and $0.2 million is U.S. Government-unfunded. The amount that is non-U.S. Government-funded includes $10.0 million of milestone payments under the EMRE Joint Development Agreement that are contingent upon achieving technical milestones.&#160;If funding is terminated or delayed or if business initiatives change, we may choose to devote resources to other activities, including internally funded research and development.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Off-Balance Sheet Arrangements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We have no off-balance sheet debt or similar obligations which are not classified as debt.

Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and right-of-use (&#8220;ROU&#8221;) assets, and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Our critical accounting policies are those that are both most important to our financial condition and results of operations and require the most difficult, subjective or complex judgments on the part of management in their application, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. For a complete description of our critical accounting policies that affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements, refer to our Annual Report on Form&#160;10-K for the&#160;year ended October&#160;31, 2020 filed with the SEC.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:center;margin:0pt 0pt 10pt 0pt;">ACCOUNTING GUIDANCE UPDATE</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">See Note&#160;2. &#8220;Recent Accounting Pronouncements,&#8221; to our Consolidated Financial Statements included in this Quarterly Report on Form&#160;10-Q for a summary of recently adopted accounting guidance.</p><a id="_94751bc9_b922_405a_a814_7ca9c00ea081"></a><a id="Item3QUANTITATIVEANDQUALITATIVEDISCLOSUR"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Item&#160;3.&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Interest Rate Exposure</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Cash is invested overnight with high credit quality financial institutions and therefore we are not exposed to market risk on our cash holdings from changing interest rates. Based on our overall interest rate exposure as of April&#160;30, 2021, including all interest rate sensitive instruments, a change in interest rates of 1% would not have a material impact on our results of operations.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Foreign Currency Exchange Risk</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">As of April&#160;30, 2021, approximately 1.0% of our total cash and cash equivalents were in currencies other than U.S. dollars (primarily the Euro, Canadian dollars and South Korean Won) and we have no plans of repatriation. We make purchases from certain vendors in currencies other than U.S. dollars. Although we have not experienced significant foreign exchange rate losses to date, we may in the future, especially to the extent that we do not engage in currency hedging activities. The economic impact of currency exchange rate movements on our operating results is complex because such changes are often linked to variability in real growth, inflation, interest rates, governmental actions and other factors. These changes, if material, may cause us to adjust our financing and operating strategies.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Derivative Fair Value Exposure Risk</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Interest Rate Swap</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On May&#160;16, 2019, an interest rate swap agreement (the &#8220;Swap Agreement&#8221;) was entered into with Fifth Third Bank in connection with the BFC Credit Agreement for the term of the loan. The net interest rate across the BFC Credit Agreement and the swap transaction results in a fixed rate of 5.09%. The interest rate swap will be adjusted to fair value on a quarterly basis. The estimated fair value is based on Level 2 inputs including primarily the forward LIBOR curve available to swap dealers. The valuation methodology involves comparison of (i)&#160;the sum of the present value of all&#160;monthly variable rate payments based on a reset rate using the forward LIBOR curve and (ii)&#160;the sum of the present value of all&#160;monthly fixed rate payments on the notional amount, which is equivalent to the outstanding principal amount of the loan. The fair value adjustments for the three&#160;months ended April&#160;30, 2021 and 2020 resulted in a gain of $0.1 million and a charge of $0.5 </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">49</p></div></div>

We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February&#160;7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February&#160;7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October&#160;27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October&#160;31, 2012 (and the amendments thereto), which are collectively referred to herein as the &#8220;License Agreements.&#8221;&#160;The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#8220;KFC&#8221;), without the Company&#8217;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#8217;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#8217;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#8217;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#8217;s failure to pay royalties required to be paid in connection with certain module exchanges.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore alleging certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and seeking combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (&#8220;KOSPO&#8221;) as part of such warranty claims, which has delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims not yet filed in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million.

The Company has requested that the arbitral tribunal (a)&#160;confirm through declaration that POSCO Energy&#8217;s exclusive license to market the Company&#8217;s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company has the right to pursue direct sales in these markets, (b)&#160;order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c)&#160;order POSCO Energy and KFC to pay the Company&#8217;s arbitration costs, including counsel fees and expenses. The Company has retained outside counsel on a contingency basis to pursue its claims, and outside counsel has entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October&#160;2020, POSCO Energy filed a counterclaim in the arbitration (x)&#160;seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y)&#160;seeking a declaration that the License Agreements remain in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy&#8217;s exclusive rights under the License Agreements and (z)&#160;seeking an order that the Company pay POSCO Energy&#8217;s arbitration costs, including counsel fees and expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company has discontinued revenue recognition of the deferred license revenue related to the terminated License Agreements given the pending arbitration and will continue to evaluate this deferred revenue in future periods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On August&#160;28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#8220;Court&#8221;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#8217;s subsidiaries pursuant to Section&#160;220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleges that it is seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#8217;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy seeks an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#8217;s fees incurred in connection with the matter, and granting such other and further relief as the Court deems just and proper.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company does not believe that any of the arbitrations or legal proceedings brought against the Company by POSCO Energy are for a proper purpose. Further, the Company believes that all such arbitrations and legal proceedings are in fact simply fulfillment of POSCO Energy&#8217;s prior threats to file a series of actions against the Company and are attempts to obtain leverage over the Company and, in certain proceedings, gain advantage in the pending arbitration filed by the Company against POSCO Energy. The Company will vigorously defend itself against POSCO Energy&#8217;s claims in all forums and believes it will be apparent at the conclusion of each matter that each action was filed for an improper purpose.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Other Legal Proceedings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (&#8220;Other Legal Proceedings&#8221;).

Those risk factors continue to be relevant to an understanding of our business, financial condition and operating results and, accordingly, you should review and consider such risk factors in making any investment decision with respect to our securities. The following risk factors are being provided to supplement and to update the risk factors set forth in Part&#160;I, Item&#160;1A, &#8220;Risk Factors&#8221; of our most recently filed Annual Report on Form&#160;10-K for the fiscal&#160;year ended October&#160;31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Our business and operations have been and may continue to be adversely affected by the 2019 novel coronavirus (COVID-19) outbreak or other similar outbreaks.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Any outbreaks of contagious diseases, including the recent outbreak of the 2019 novel coronavirus (&#8220;COVID-19&#8221;) that was first detected in Wuhan, China in December&#160;2019 and has since developed into a global pandemic, and other adverse public health developments in countries where we and our suppliers operate, could have a material and adverse effect on our business, financial condition and results of operations. These effects could include disruptions to or restrictions on our employees&#8217; ability to travel, as well as temporary closures of our facilities or the facilities of our customers, suppliers, or other vendors in our supply chain. In addition, COVID-19 has resulted in a widespread health crisis that has adversely affected, and may continue to adversely affect, the economies and financial markets of many countries, resulting in an economic downturn that could affect demand for our products or our ability to obtain financing for our business or projects. COVID-19 may impact the health of our team members, directors or customers, reduce the availability of our workforce or those of companies with which we do business, or otherwise cause human impacts that may negatively impact our business. Any of these events, which may result in disruptions to our supply chain or customer demand, could materially and adversely affect our business and our financial results. The extent to which COVID-19 will impact our business and our financial results will depend on future developments, which are highly uncertain and cannot be predicted. Such developments may include the geographic spread of COVID-19, the severity of the disease, the duration of the outbreak, the actions that may be taken by various governmental authorities in response to the outbreak, such as quarantine or &#8220;shelter-in-place&#8221; orders and business closures imposed by various states within the United States, and the impact on the U.S. or global economy. For example, on March&#160;18, 2020, in response to the escalating global COVID-19 outbreak, we temporarily suspended operations at our Torrington, Connecticut manufacturing facility, and also ordered those employees that could work from home to do so. We resumed operations in the manufacturing facility on June&#160;22, 2020, and we established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home that was completed April 19, 2021 with all U.S.-based employees being back in the office. However, we continue to evaluate our ability to operate in the event of resurgences of COVID-19 and the advisability of continuing operations, based on federal, state and local guidance, evolving data concerning the pandemic and the best interests of our employees, customers and stockholders. Accordingly, there can be no assurance that any of our facilities will remain open (in full or in part) or that our other operations will continue at full or limited capacity. If we again have to shut down production either due to a resurgence of the COVID-19 pandemic or due to an outbreak in one of our facilities, our project schedules and associated financing could be adversely affected. Further, we have experienced, and may continue to experience, increased costs and expenses, including as a result of (i)&#160;conducting daily &#8220;fitness-for-duty&#8221; assessments for employees, including symptom checks and providing personal protective equipment, (ii)&#160;the expansion of benefits to our employees, including the provision of additional time off for employees who have contracted COVID-19 or are required to be quarantined or who are unable to obtain childcare to return to work, and the reimbursement of expenses incurred while working from home, (iii)&#160;implementing increased health and safety protocols at all of our facilities, including increased cleaning/sanitization of workspaces, restricting visitor access, mandating social distancing guidelines and increasing the availability of sanitization products, and (iv)&#160;the increased cost of personal protective equipment. Although we believe the Company is currently considered an &#8220;essential&#8221; business in its operating markets, if any of the applicable exceptions or exemptions are curtailed or revoked in the future, or any of these exemptions or exceptions do not extend to any of our key suppliers, our business, operating results and financial condition could be adversely impacted. While we have attempted to continue business development activities during the pandemic, state and local shutdowns, shelter-in-place orders and travel restrictions have impeded our ability to meet with customers and solicit new business, and certain bids and solicitations in which we typically participate have been postponed. As a result, at this time, it is impossible to predict the overall impact of COVID-19 on our business, liquidity, capital resources, supply chain and financial results or its effect on clean energy demand, capital budgets of our customers, or demand for our products. Additionally, while we have continued to prioritize the health and safety of our team members and customers as we continue to operate during the pandemic, we face an increased risk of litigation related to our operating environments. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">53</p></div></div>

Additional public health crises could also emerge in the future, including other pandemics or epidemics. Any such public health crisis could pose further risks to us and could also have a material adverse effect on our business, results of operations and financial position.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Our PPP Loan may subject us to challenges regarding qualification for the PPP Loan, enforcement actions, fines and penalties, and has resulted in an informal SEC inquiry into our financial disclosures.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On April&#160;20, 2020, we entered into a Paycheck Protection Program Promissory Note, dated April&#160;16, 2020 (the &#8220;PPP Note&#8221;), evidencing a loan to the Company from Liberty Bank under the CARES Act. Pursuant to the PPP Note, we received total proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#8220;PPP Loan&#8221;). In accordance with the requirements of the CARES Act, as amended by the Paycheck Protection Program Flexibility Act of 2020 (the &#8220;PPP Flexibility Act&#8221;), the PPP Loan may have been fully forgiven if (i)&#160;proceeds were used to pay eligible payroll costs, rent, mortgage interest and utilities and (ii)&#160;full-time employee headcount and salaries were either maintained during the 24-week period following disbursement of the PPP Loan or restored by December&#160;31, 2020. If not so maintained or restored, forgiveness of the PPP Loan would have been reduced in accordance with regulations issued by the SBA. In order to obtain the consent of the Orion Agent and the lenders under the Orion Credit Agreement (each as defined elsewhere in this document) to enter into the PPP Note, the Orion Agent and such lenders required us to apply for forgiveness within 30&#160;days after the last day of the loan forgiveness period as designated under regulations in effect as of June&#160;6, 2020. We used 100% of the proceeds of the PPP Loan to pay eligible payroll costs, and on October&#160;29, 2020, we applied for forgiveness of the PPP Loan. However, with the repayment in full of all amounts owed to the Orion Agent and lenders in December 2020, the Company was no longer required to pursue forgiveness of the PPP Loan. Additionally, since the time of the application for forgiveness, the Company&#8217;s financial circumstances changed substantially, such that the Company was no longer in need of forgiveness of the PPP Loan. While we believe we met all of the requirements of the CARES Act, as amended by the PPP Flexibility Act, for forgiveness, on February&#160;11, 2021, we withdrew our application for forgiveness and repaid all amounts outstanding under the PPP Note, together with all accrued interest.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In addition, based on guidance from the United States Department of the Treasury, since the total PPP Loan proceeds exceeded $2.0 million, our forgiveness application is subject to audit by the SBA, including with respect to our certification that the economic uncertainty at the time of our application made our request for a PPP Loan necessary to support our ongoing operations. If we are found to have been ineligible to receive the PPP Loan under the PPP Note, or in violation of any of the laws or regulations that may apply to us in connection with the PPP Note, including the False Claims Act, we may be subject to enforcement actions, fines and penalties, including significant civil, criminal and administrative penalties. In addition, our receipt of the PPP Loan, our submission of a forgiveness application, and our withdrawal of our forgiveness application may result in adverse publicity and damage to our reputation, governmental investigations, inquiries, reviews and audits, such as the SEC inquiry described below, which could consume significant financial and management resources. Any of these events could harm our business, results of operations and financial condition.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On or about May&#160;11, 2020, the Division of Enforcement of the SEC sent the Company an inquiry requesting that we voluntarily provide information to the SEC pertaining to our application and resulting PPP Loan and how the need for the PPP Loan compares with our filings, disclosures and financial condition. While this request for information is voluntary and the Company was not obligated to respond, we are cooperating and have provided information to the SEC.</p><a id="_f497fc66_de4e_4bf8_b001_5ea5d0aeb2cf"></a><a id="Item2UNREGISTEREDSALESOFEQUITYSECURITIES"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Item&#160;2.&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS</p><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:10pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:24.5pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:24pt;padding:0pt;">(a)</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">None.</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:10pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:24.5pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:24pt;padding:0pt;">(b)</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Not applicable.</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:24.5pt;"></td><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:24pt;padding:0pt;">(c)</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Stock Repurchases</span></td></tr></table><div style="margin-top:10pt;"></div></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">54</p></div></div>

Therefore, from time to time, the Company may consider &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;and enter into agreements for one or more of the following: negotiated financial transactions, minority investments, collaborative ventures, license arrangements, joint ventures or other business transactions for the purpose(s) of geographic or manufacturing expansion and/or new product or technology development and commercialization. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Our business model requires substantial outside financing arrangements and satisfaction of the conditions of such financing arrangements to construct and deploy our projects and facilitate the growth of our business. The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future. If financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to reduce or slow planned spending, reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.&lt;/p&gt;</fcel:LiquidityPolicyTextBlock>

The contract assets relate to the Company&#x2019;s rights to consideration for work performed but not billed. These amounts are included on a separate line item as Unbilled receivables, and balances expected to be billed later than one&#160;year from the balance sheet date are included within Other assets on the accompanying Consolidated Balance Sheets.

The contract liabilities relate to the advance billings to customers for services that will be recognized over time and in some instances for deferred revenue relating to license performance obligations that will be recognized at a future point in time. The Company has discontinued revenue recognition of the deferred license revenue related to the terminated POSCO Energy License Agreements (as defined elsewhere herein) given the pending arbitration, described in Part II, Item 1, &#x201c;Legal Proceedings,&#x201d; and will continue to evaluate this deferred revenue in future periods (for more information, refer to Note&#160;18. &#x201c;Commitments and Contingencies&#x201d;). As of April&#160;30, 2021, $22.2 million related to the terminated POSCO Energy License Agreements is included within Long-term deferred revenue on the accompanying Consolidated Balance Sheets. The net change in contract liabilities represents customer billings offset by revenue recognized.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;"&gt;Remaining Performance Obligations&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Remaining performance obligations are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied.

Leases&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;The Company enters into operating and finance lease agreements for the use of real estate, vehicles, information technology equipment, and certain other equipment. We determine if an arrangement contains a lease at inception, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. Operating leases are included in Operating lease right-of-use assets, net, Operating lease liabilities, and Long-term operating lease liabilities in the Company&#x2019;s Consolidated Balance Sheets. Finance leases are not considered significant to the Company&#x2019;s Consolidated Balance Sheets or Consolidated Statements of Operations and Comprehensive Loss. Finance lease right of use (&#x201c;ROU&#x201d;) assets at April&#160;30, 2021 and October&#160;31, 2020 of $0.1 million and $0.04 million, respectively, are included in Property, plant and equipment, net in the Company&#x2019;s Consolidated Balance Sheets. Finance lease liabilities at April&#160;30, 2021 and October&#160;31, 2020 of $0.1 million and $0.04 million, respectively, are included in Current portion of long-term debt and Long-term debt and other liabilities in the Company&#x2019;s Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;ROU assets represent the Company&#x2019;s right to use an underlying asset for the lease term and lease liabilities represent the present value of the Company&#x2019;s obligation to make lease payments arising from the lease over the lease term at the commencement date of the lease. As most of the Company&#x2019;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#x2019;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#x2019;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities, to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense. The Company&#x2019;s leases generally have remaining lease terms of 1 to 26&#160;years, some of which include options to extend leases. The exercise of lease renewal options is at the Company&#x2019;s sole discretion and the Company&#x2019;s lease ROU assets and liabilities reflect only the options the Company is reasonably certain that it will exercise. We do not have leases with residual value guarantees or similar covenants.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Operating lease expense for the three&#160;months ended April&#160;30, 2021 and 2020 was $0.4 million and $0.1 million, respectively, and for the six&#160;months ended April&#160;30, 2021 and 2020 was $0.8 million and $0.3 million, respectively. As of April&#160;30, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20&#160;years and the weighted average discount rate was 7.8%. Lease payments made during the three&#160;months ended April&#160;30, 2021 and 2020 were $0.3 million and $0.2 million, respectively, and during the six months ended April 30, 2021 and 2020 were $0.6 million and $0.5 million, respectively.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Undiscounted maturities of

Because these Orion Warrants were exercised on a cashless basis, the Company issued in the aggregate 9,396,320 shares of the Company&#x2019;s common stock. The Orion Warrants that were converted were remeasured to fair value immediately preceding the conversion based upon volatility of 103.7%, a risk free rate of 1.81% and the Company&#x2019;s common stock price of $2.29 on January&#160;8, 2020, which resulted in a $23.7 million charge for the three&#160;months ended January&#160;31, 2020. The revised estimated fair value of the converted Orion Warrants as of the date of conversion of $26.0 million was reclassified to Additional paid in capital. The remaining Orion Warrants as of January&#160;31, 2020 were remeasured to estimated fair value based upon a volatility of 104.9%, a risk free rate of 1.45% and the Company&#x2019;s common stock price at January&#160;31, 2020 of $1.59 per share, which resulted in a charge for the three&#160;months ended January&#160;31, 2020 of $10.5 million. &#160;The Company remeasured the remaining Orion Warrants again at April 30, 2020 based upon a volatility of 107.4%, a risk free rate of 0.57% and the Company&#x2019;s common stock price at April 30, 2020 of $2.02 per share, which resulted in a charge for the three months ended April 30, 2020 of $3.4 million. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;During fiscal&#160;year 2020, the lenders exercised all of the Orion Warrants, except for Orion Warrants to purchase 2,700,000 shares of common stock. On December&#160;7, 2020, all remaining Orion Warrants were exercised to purchase a total of 2,700,000 shares of the Company&#x2019;s common stock for an aggregate exercise price of $653,400 (or $0.242 per share). The Orion Warrants that were converted on December&#160;7, 2020 were remeasured to fair value immediately preceding the conversion based upon volatility of 117.02%, a risk free rate of 0.70% and the Company&#x2019;s common stock price of $7.95 on December&#160;4, 2020, which resulted in a $16.0 million charge for the three&#160;months ended January&#160;31, 2021. The estimated fair value of the converted Orion Warrants as of the December 7, 2020 date of conversion of $21.2 million was reclassified to Additional paid in capital.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 10pt 0pt;"&gt;&lt;span style="text-decoration:underline;"&gt;Other Warrants&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On May&#160;3, 2017, the Company completed an underwritten public offering that included the offering and sale of: (i)&#160;1,000,000 shares of its common stock, and (ii)&#160;Series&#160;C warrants to purchase 1,000,000 shares of its common stock that have an exercise price of $19.20 per share and a term of five&#160;years. During the three and six months ended April 30, 2021, Series C warrants were exercised to purchase a total of 14,026 shares of the Company&#x2019;s common stock resulting in cash proceeds to the Company of $0.3 million.

(&#x201c;Enbridge&#x201d;). Dividends and return of capital payments were due quarterly based on calendar quarters. The Company made payments of Cdn. $0.3 million and $1.5 million during the three-month and six-month periods ended April&#160;30, 2020, respectively. The Company&#x2019;s payments made during the six-months ended April&#160;30, 2020 included the payments which were not made previously for the calendar quarters ended on March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. The Company recorded interest expense, which reflects the amortization of the fair value discount of approximately Cdn. $0.7 million for the three months ended April 30, 2020 and Cdn. $0.6 million and Cdn. $1.3 million for the six&#160;months ended April&#160;30, 2021 and 2020, respectively. There was no interest expense recorded for the three months ended April 30, 2021. As of October&#160;31, 2020, the carrying value of the Series&#160;1 Preferred Shares was Cdn. $25.6 million (U.S. $19.2 million) and was classified as a preferred stock obligation of a subsidiary on the Consolidated Balance Sheets.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On January&#160;20, 2020, the Company, FCE&#160;Ltd. and Enbridge entered into a letter agreement (the &#x201c;January&#160;2020 Letter Agreement&#x201d;), pursuant to which they agreed to amend the articles of FCE&#160;Ltd. relating to and setting forth the terms of the Series&#160;1 Preferred Shares to: (i)&#160;remove the provisions of the articles permitting or requiring the issuance of shares of the Company&#x2019;s common stock in exchange for the Series&#160;1 Preferred Shares or as payment of amounts due to the holders of the Series&#160;1 Preferred Shares, (ii)&#160;remove certain provisions of the articles relating to the redemption of the Series&#160;1 Preferred Shares, (iii)&#160;increase the annual dividend rate, commencing on January&#160;1, 2020, to 15%, (iv)&#160;extend the final payment date for all accrued and unpaid dividends and all return of capital payments (i.e., payments of the principal redemption price) from December&#160;31, 2020 to December&#160;31, 2021, (v)&#160;clarify when dividend and return of capital payments are to be made in the future and extend the quarterly dividend and return of capital payments through December&#160;31, 2021 (which were previously to be paid each quarter through December&#160;31, 2020), (vi)&#160;remove certain terms and provisions of the articles that were no longer applicable, and (vii)&#160;make other conforming changes to the articles. In addition, the parties agreed to amend the Company&#x2019;s guarantee in favor of Enbridge (the &#x201c;Guarantee&#x201d;) as necessary or as the parties may mutually agree, in either case, in order to be consistent with such amended articles and to maintain the Company&#x2019;s guarantee of FCE&#160;Ltd.&#x2019;s obligations under the Series&#160;1 Preferred Shares. The articles of FCE&#160;Ltd. were amended and filed in accordance with the provisions of the January&#160;2020 Letter Agreement on March&#160;26, 2020. Under the terms of the January&#160;2020 Letter Agreement, the Company was still required to make (i)&#160;annual dividend payments of Cdn. $500,000 and (ii)&#160;annual return of capital payments of Cdn. $750,000. Dividend and return of capital payments were to be made on a quarterly basis and were scheduled to end on December&#160;31, 2021 unless these obligations were satisfied in advance of such date.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;The amendment to the Series&#160;1 Preferred Shares resulted in an extinguishment of the prior Series&#160;1 Preferred Shares for accounting purposes. A revised fair value was estimated using a discounted cash flow model resulting in a revised carrying value being recorded for the amended Series&#160;1 Preferred Shares which resulted in a loss of Cdn. $0.2 million (U.S. $0.2 million) recorded in Other (expense) income, net on the Consolidated Statements of Operations and Comprehensive Loss during the three&#160;months ended January&#160;31, 2020.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Prior to the amendment, the Company bifurcated embedded derivatives related to the conversion feature and a variable dividend feature. As a result of the January&#160;2020 Letter Agreement, both features were removed from the Series&#160;1 Preferred Shares which resulted in the Company recognizing a gain of U.S. $0.6 million related to the extinguishment of the embedded derivatives during the six&#160;months ended April&#160;30, 2020.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;In December&#160;2020, the Company, FCE&#160;Ltd., and Enbridge entered into a payoff letter, pursuant to which the Company paid all amounts owed to Enbridge under the terms of the Series&#160;1 Preferred Shares. As of the date of the payoff letter, the amount owed to Enbridge under the Series&#160;1 Preferred Shares totaled Cdn. $27.4 million, which included Cdn. $4.3 million of principal and Cdn. $23.1 million of accrued dividends.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On December&#160;18, 2020, the Company remitted payment totaling&#160;Cdn. $27.4 million, or approximately U.S. $21.5 million, to Enbridge. Upon making the payment, the Company recorded a loss on extinguishment for the Series&#160;1 Preferred Shares of $0.9 million. Concurrent with receipt of the payment from the Company, Enbridge surrendered its Series&#160;1 Preferred Shares in FCE&#160;Ltd., and the Guarantee and the January&#160;2020 Letter Agreement were terminated. All obligations related to the Series&#160;1 Preferred Shares were extinguished upon payment.&lt;/p&gt;</us-gaap:PreferredStockTextBlock>

Partners Investment Agent, LLC Credit Agreement&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On November&#160;30, 2020, the Company, its subsidiary guarantors, and the Orion Agent entered into a payoff letter with respect to the Orion Credit Agreement (the &#x201c;Orion Payoff Letter&#x201d;). Pursuant to the Orion Payoff Letter, on December&#160;7, 2020, the Company paid a total of $87.3 million to the Orion Agent, representing the outstanding principal, accrued but unpaid interest, prepayment premium, fees, costs and other expenses due and owing under the Orion Facility and the Orion Credit Agreement and related loan documents, in full repayment of the Company&#x2019;s outstanding indebtedness under the &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Orion Facility and the Orion Credit Agreement and related loan documents. In accordance with the Orion Payoff Letter, the aggregate prepayment premium set forth in the Orion Credit Agreement was reduced from approximately $14.9 million to $4.0 million and the Orion Agent, on behalf of itself and the lenders, agreed that any portion of the prepayment premium that would otherwise be required to be paid pursuant to the Orion Credit Agreement in excess of $4.0 million was waived by the Orion Agent and the lenders. The Company expensed the remaining deferred finance costs and debt discount of $7.1 million. The Company has classified the $4.0 million prepayment premium and the deferred finance costs and debt discount expense as Loss on extinguishment of debt on the Consolidated Statements of Operations and Comprehensive Loss.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Concurrently with the Orion Agent&#x2019;s receipt of full payment pursuant to the Orion Payoff Letter, the Orion Agent released all of the collateral from the liens granted under the security documents associated with the Orion Facility (which included the release of $11.2 million of restricted cash to the Company, which became unrestricted cash), and the Company and its subsidiaries were unconditionally released from their respective obligations under the Orion Credit Agreement (and related loan documents) and the Orion Facility without further action. With the termination of the Orion Facility and the Orion Credit Agreement and related loan documents, the lenders no longer have the right to appoint representatives to attend the Company&#x2019;s Board of Director meetings as observers.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;"&gt;Liberty Bank Promissory Note&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On April&#160;20, 2020, the Company entered into the PPP Note (as defined elsewhere herein), dated April&#160;16, 2020, evidencing a loan to the Company from Liberty Bank under the CARES Act (as defined elsewhere herein), administered by the U.S. Small Business Administration. Pursuant to the PPP Note, the Company received total loan proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#x201c;PPP Loan&#x201d;).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;As required by the Orion Agent and its affiliated lenders (collectively, &#x201c;Orion&#x201d;) under the Company&#x2019;s (now former) senior secured credit facility, the Company applied for forgiveness of the PPP Loan in October 2020.&#160;However, with the repayment in full of all amounts owed to Orion in December 2020, the Company was no longer required to pursue forgiveness of the PPP Loan. Additionally, since the time of the application for forgiveness, the Company&#x2019;s financial circumstances changed substantially, such that the Company was no longer in need of forgiveness of the PPP Loan. Accordingly, on February 11, 2021, the Company withdrew its application for forgiveness and repaid all amounts outstanding under the PPP Note.&lt;/p&gt;</us-gaap:DebtDisclosureTextBlock>

During the six&#160;months ended April&#160;30, 2021, the Company approved a sub-plan to its 2018 Omnibus Incentive Plan, as amended and restated, which is described in more detail below.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;"&gt;2018 Omnibus Incentive Plan&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;The Company&#x2019;s 2018 Omnibus Incentive Plan (as amended and restated from time to time, the &#x201c;2018 Incentive Plan&#x201d;) authorizes grants of stock options, stock appreciation rights (&#x201c;SARs&#x201d;), restricted stock awards (&#x201c;RSAs&#x201d;), restricted stock units (&#x201c;RSUs&#x201d;), performance shares, performance units and incentive awards to employees, directors, consultants and advisors. Stock options, RSAs and SARs have restrictions as to transferability. Stock option exercise prices are fixed by the Company&#x2019;s Board of Directors but shall not be less than the fair market value of our common stock on the date of the grant. SARs may be granted in conjunction with stock options.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On November&#160;24, 2020, the Company&#x2019;s Board of Directors approved a Long Term Incentive Plan (the &#x201c;LTI Plan&#x201d;) as a sub-plan consisting of awards made under the 2018 Incentive Plan.&#160;The participants in the LTI Plan are members of senior management and include the Company&#x2019;s named executive officers (as identified in the definitive proxy statement filed by the Company on February&#160;19, 2021). The LTI Plan consists of three award components: (1)&#160;relative total shareholder return (&#x201c;TSR&#x201d;) performance units, (2)&#160;absolute TSR performance units, and (3)&#160;time-vesting restricted stock units.&#160;The performance units granted during the three&#160;months ended January&#160;31, 2021 will be earned over the performance period ending on October&#160;31, 2023, but will remain subject to a continued service-based vesting requirement until the third anniversary of the date of grant.&#160;The performance measure for the relative TSR performance units is the TSR of the &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Company relative to the TSR of the Russell 2000 from November&#160;1, 2020 through October&#160;31, 2023.&#160;The performance measure for the absolute TSR performance units is an increase in the Company&#x2019;s stock price during the performance period of November&#160;1, 2020 through October&#160;31, 2023.&#160;The time-vesting RSUs granted during the three&#160;months ended January&#160;31, 2021 will vest at a rate of one-third of the total number of RSUs on each of the first three anniversaries of the date of grant.&#160;None of the awards granted as part of the LTI Plan include any dividend equivalent or other stockholder rights.&#160;To the extent the awards are earned, they may be settled in shares or cash of an equivalent value at the Company&#x2019;s option.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On November&#160;24, 2020, 848,078 RSUs were awarded under the LTI Plan, which include 551,252 performance units and 296,826 time-based units. Should the Company&#x2019;s share price achieve the 200% performance level, awardees will receive up to 551,252 additional RSUs. The performance units were valued based on a Monte-Carlo Simulation, and the estimated fair value of the 275,626 relative TSR performance units are $14.41 per share and the estimated fair value of the 275,626 absolute TSR performance units are $15.36 per share. The performance units and time-based units will be expensed over the three-year service period.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On April 8, 2021, the Company&#x2019;s stockholders approved an amendment and restatement of the 2018 Incentive Plan to authorize the Company to issue up to 8,000,000 additional shares of the Company&#x2019;s common stock.  Following the approval of the amendment and restatement, the Company has the authority to issue a total of 12,333,333 shares of the Company&#x2019;s common stock.&lt;/p&gt;&lt;p

Under the terms of such service agreements, the particular power plant must meet a minimum operating output during defined periods of the term. If minimum output falls below the contract requirement, the Company may be subject to performance penalties and/or may be required to repair or replace the customer&#x2019;s fuel cell module(s).&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;"&gt;Power Purchase Agreements&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;Under the terms of the Company&#x2019;s PPAs, customers agree to purchase power from the Company&#x2019;s fuel cell power plants at negotiated rates.

As owner or lessee of the power plants, the Company is responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, the Company is also responsible for procuring fuel, generally natural gas or biogas, to run the power plants.

(&#x201c;POSCO Energy&#x201d;) to develop and grow the South Korean and Asian markets for our products and services. We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February&#160;7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February&#160;7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October&#160;27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October&#160;31, 2012 (and the amendments thereto), which are collectively referred to herein as the &#x201c;License Agreements.&#x201d;&#160;The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#x201c;KFC&#x201d;), without the Company&#x2019;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#x2019;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#x2019;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#x2019;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#x2019;s failure to pay royalties required to be paid in connection with certain module exchanges.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore alleging certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and seeking combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (&#x201c;KOSPO&#x201d;) as part &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;of such warranty claims, which has delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims not yet filed in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of April&#160;30, 2021, outstanding accounts receivable due from KOSPO were $8.0 million. POSCO Energy posted a bond in the amount of $46 million to secure any damages to the Company resulting from the attachments.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On June&#160;28, 2020, the Company terminated the License Agreements with POSCO Energy and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy&#x2019;s (i)&#160;failure to exercise commercially reasonable efforts to sell the Company&#x2019;s technology in the South Korean and Asian markets, (ii)&#160;disclosure of the Company&#x2019;s proprietary information to third parties, (iii)&#160;attack on the Company&#x2019;s stock price and (iv)&#160;spin-off of POSCO Energy&#x2019;s fuel cell business into KFC without the Company&#x2019;s consent. The Company has requested that the arbitral tribunal (a)&#160;confirm through declaration that POSCO Energy&#x2019;s exclusive license to market the Company&#x2019;s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company has the right to pursue direct sales in these markets, (b)&#160;order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c)&#160;order POSCO Energy and KFC to pay the Company&#x2019;s arbitration costs, including counsel fees and expenses. The Company has retained outside counsel on a contingency basis to pursue its claims, and outside counsel has entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October&#160;2020, POSCO Energy filed a counterclaim in the arbitration (x)&#160;seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y)&#160;seeking a declaration that the License Agreements remain in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy&#x2019;s exclusive rights under the License Agreements and (z)&#160;seeking an order that the Company pay POSCO Energy&#x2019;s arbitration costs, including counsel fees and expenses.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;The Company has discontinued revenue recognition of the deferred license revenue related to the terminated License Agreements given the pending arbitration and will continue to evaluate this deferred revenue in future periods.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On August&#160;28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#x201c;Court&#x201d;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#x2019;s subsidiaries pursuant to Section&#160;220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleges that it is seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#x2019;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy seeks an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#x2019;s fees incurred in connection with the matter, and granting such other and further relief as the Court deems just and proper.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1 million.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;The Company does not believe that any of the arbitrations or legal proceedings brought against the Company by POSCO Energy are for a proper purpose. Further, the Company believes that all such arbitrations and legal proceedings are in fact simply fulfillment of POSCO Energy&#x2019;s prior threats to file a series of actions against the Company and are attempts to obtain leverage over the Company and, in certain proceedings, gain advantage in the pending arbitration filed by the Company against POSCO Energy. The Company will vigorously defend itself against POSCO Energy&#x2019;s claims in all forums and believes it will be apparent at the conclusion of each matter that each action was filed for an improper purpose.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;"&gt;Other Legal Proceedings&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;"&gt;From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (&#x201c;Other Legal Proceedings&#x201d;). Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company&#x2019;s consolidated financial statements, and no material amounts have been accrued in the Company&#x2019;s consolidated financial statements with respect to these matters.&lt;/p&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

Nature of Business and Basis of Presentation</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">FuelCell Energy,&#160;Inc., together with its subsidiaries (the &#8220;Company&#8221;, &#8220;FuelCell Energy&#8221;, &#8220;we&#8221;, &#8220;us&#8221;, or &#8220;our&#8221;), is a leading integrated fuel cell company.

Accordingly, they do not contain all of the information and footnotes required by accounting principles generally accepted in the United States of America (&#8220;GAAP&#8221;) for complete financial statements. In the opinion of management, all normal and recurring adjustments necessary to fairly present the Company&#8217;s financial position and results of operations as of and for the three and six&#160;months ended April&#160;30, 2021 and 2020 have been included. All intercompany accounts and transactions have been eliminated.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The balance sheet as of October&#160;31, 2020 has been derived from the audited financial statements at that date, but it does not include all of the information and footnotes required by GAAP for complete financial statements.&#160;These financial statements should be read in conjunction with the Company&#8217;s financial statements and notes thereto for the fiscal&#160;year ended October&#160;31, 2020, which are contained in the Company&#8217;s Annual Report on Form&#160;10-K previously filed with the SEC. The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for any other interim period or for the full fiscal&#160;year.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Use of Estimates</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and right-of-use (&#8220;ROU&#8221;) assets, and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Liquidity</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Our principal sources of cash have been sales of our common stock through public equity offerings, proceeds from third party debt such as borrowings under our credit facilities, project financing and tax monetization transactions, proceeds from the sale of our projects as well as research and development and service and license agreements with third parties.

The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future. If financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to reduce or slow planned spending, reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.</p><span></span>

The contract assets relate to the Company&#8217;s rights to consideration for work performed but not billed. These amounts are included on a separate line item as Unbilled receivables, and balances expected to be billed later than one&#160;year from the balance sheet date are included within Other assets on the accompanying Consolidated Balance Sheets. The net change in contract assets represents amounts recognized as revenue offset by customer billings.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Contract liabilities as of April&#160;30, 2021 and October&#160;31, 2020 were $44.2 million and $41.9 million, respectively. The contract liabilities relate to the advance billings to customers for services that will be recognized over time and in some instances for deferred revenue relating to license performance obligations that will be recognized at a future point in time. The Company has discontinued revenue recognition of the deferred license revenue related to the terminated POSCO Energy License Agreements (as defined elsewhere herein) given the pending arbitration, described in Part II, Item 1, &#8220;Legal Proceedings,&#8221; and will continue to evaluate this deferred revenue in future periods (for more information, refer to Note&#160;18. &#8220;Commitments and Contingencies&#8221;). As of April&#160;30, 2021, $22.2 million related to the terminated POSCO Energy License Agreements is included within Long-term deferred revenue on the accompanying Consolidated Balance Sheets. The net change in contract liabilities represents customer billings offset by revenue recognized.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Remaining Performance Obligations</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Remaining performance obligations are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of April&#160;30, 2021, the Company&#8217;s total remaining performance obligations were: $141.4 million for service agreements, $22.2 million for license agreements and $45.0 million for Advanced Technologies contracts in </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">the aggregate. Service revenue in periods in which there are no module exchanges is expected to be relatively consistent from period to period, whereas module exchanges will result in an increase in revenue when exchanges occur.</p><span></span>

Certain of these assets are the subject of sale-leaseback arrangements with PNC Energy Capital, LLC (&#8220;PNC&#8221;) and Crestmark Equipment Finance (&#8220;Crestmark&#8221;). Project asset depreciation was approximately $3.3 million and $2.8 million for the three&#160;months ended April&#160;30, 2021 and 2020, respectively, and $7.3 million and $5.8 million for the six&#160;months ended April&#160;30, 2021 and 2020, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Project assets as of April&#160;30, 2021 and October&#160;31, 2020 also include installations with carrying values of $97.9 million and $91.3 million, respectively, which are being developed and constructed by the Company in connection with projects for which we have entered into PPAs or projects for which we expect to secure PPAs or otherwise recover the asset value and which have not yet been placed in service. Of these totals, as of each of April&#160;30, 2021 and October&#160;31, 2020, approximately $4.8 million relates to projects for which we expect to secure long-term contracts and/or otherwise recover the asset value and which have not yet been placed in service.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Project construction costs incurred for long-term project assets are reported as investing activities in the Consolidated Statements of Cash Flows. The proceeds received from the sale and subsequent leaseback of project assets are classified as &#8220;Cash flows from financing activities&#8221; within the Consolidated Statements of Cash Flows and are classified as a financing obligation within &#8220;Current portion of long-term debt&#8221; and &#8220;Long-term debt and other liabilities&#8221; on the Consolidated Balance Sheets (refer to Note&#160;16. &#8220;Debt&#8221; for more information).</p><span></span>

<td class="text"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Note&#160;11. Leases</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company enters into operating and finance lease agreements for the use of real estate, vehicles, information technology equipment, and certain other equipment. We determine if an arrangement contains a lease at inception, which is the date on which the terms of the contract are agreed to and the agreement creates enforceable rights and obligations. Operating leases are included in Operating lease right-of-use assets, net, Operating lease liabilities, and Long-term operating lease liabilities in the Company&#8217;s Consolidated Balance Sheets. Finance leases are not considered significant to the Company&#8217;s Consolidated Balance Sheets or Consolidated Statements of Operations and Comprehensive Loss. Finance lease right of use (&#8220;ROU&#8221;) assets at April&#160;30, 2021 and October&#160;31, 2020 of $0.1 million and $0.04 million, respectively, are included in Property, plant and equipment, net in the Company&#8217;s Consolidated Balance Sheets. Finance lease liabilities at April&#160;30, 2021 and October&#160;31, 2020 of $0.1 million and $0.04 million, respectively, are included in Current portion of long-term debt and Long-term debt and other liabilities in the Company&#8217;s Consolidated Balance Sheets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">ROU assets represent the Company&#8217;s right to use an underlying asset for the lease term and lease liabilities represent the present value of the Company&#8217;s obligation to make lease payments arising from the lease over the lease term at the commencement date of the lease. As most of the Company&#8217;s leases do not provide an implicit rate, the Company estimated the incremental borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company&#8217;s operating lease ROU assets also include any lease pre-payments and exclude lease incentives. Certain of the Company&#8217;s leases include variable payments, which may vary based upon changes in facts or circumstances after the start of the lease. The Company excludes variable payments from lease ROU assets and lease liabilities, to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. Variable lease expense and lease expense for short term contracts are not material components of lease expense. The Company&#8217;s leases generally have remaining lease terms of 1 to 26&#160;years, some of which include options to extend leases. The exercise of lease renewal options is at the Company&#8217;s sole discretion and the Company&#8217;s lease ROU assets and liabilities reflect only the options the Company is reasonably certain that it will exercise. We do not have leases with residual value guarantees or similar covenants.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Operating lease expense for the three&#160;months ended April&#160;30, 2021 and 2020 was $0.4 million and $0.1 million, respectively, and for the six&#160;months ended April&#160;30, 2021 and 2020 was $0.8 million and $0.3 million, respectively. As of April&#160;30, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20&#160;years and the weighted average discount rate was 7.8%. Lease payments made during the three&#160;months ended April&#160;30, 2021 and 2020 were $0.3 million and $0.2 million, respectively, and during the six months ended April 30, 2021 and 2020 were $0.6 million and $0.5 million, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Undiscounted maturities of operating

Because these Orion Warrants were exercised on a cashless basis, the Company issued in the aggregate 9,396,320 shares of the Company&#8217;s common stock.

The revised estimated fair value of the converted Orion Warrants as of the date of conversion of $26.0 million was reclassified to Additional paid in capital.

The Company made payments of Cdn. $0.3 million and $1.5 million during the three-month and six-month periods ended April&#160;30, 2020, respectively. The Company&#8217;s payments made during the six-months ended April&#160;30, 2020 included the payments which were not made previously for the calendar quarters ended on March&#160;31, 2019, June&#160;30, 2019 and September&#160;30, 2019. The Company recorded interest expense, which reflects the amortization of the fair value discount of approximately Cdn. $0.7 million for the three months ended April 30, 2020 and Cdn. $0.6 million and Cdn. $1.3 million for the six&#160;months ended April&#160;30, 2021 and 2020, respectively. There was no interest expense recorded for the three months ended April 30, 2021. As of October&#160;31, 2020, the carrying value of the Series&#160;1 Preferred Shares was Cdn. $25.6 million (U.S. $19.2 million) and was classified as a preferred stock obligation of a subsidiary on the Consolidated Balance Sheets.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On January&#160;20, 2020, the Company, FCE&#160;Ltd. and Enbridge entered into a letter agreement (the &#8220;January&#160;2020 Letter Agreement&#8221;), pursuant to which they agreed to amend the articles of FCE&#160;Ltd. relating to and setting forth the terms of the Series&#160;1 Preferred Shares to: (i)&#160;remove the provisions of the articles permitting or requiring the issuance of shares of the Company&#8217;s common stock in exchange for the Series&#160;1 Preferred Shares or as payment of amounts due to the holders of the Series&#160;1 Preferred Shares, (ii)&#160;remove certain provisions of the articles relating to the redemption of the Series&#160;1 Preferred Shares, (iii)&#160;increase the annual dividend rate, commencing on January&#160;1, 2020, to 15%, (iv)&#160;extend the final payment date for all accrued and unpaid dividends and all return of capital payments (i.e., payments of the principal redemption price) from December&#160;31, 2020 to December&#160;31, 2021, (v)&#160;clarify when dividend and return of capital payments are to be made in the future and extend the quarterly dividend and return of capital payments through December&#160;31, 2021 (which were previously to be paid each quarter through December&#160;31, 2020), (vi)&#160;remove certain terms and provisions of the articles that were no longer applicable, and (vii)&#160;make other conforming changes to the articles. In addition, the parties agreed to amend the Company&#8217;s guarantee in favor of Enbridge (the &#8220;Guarantee&#8221;) as necessary or as the parties may mutually agree, in either case, in order to be consistent with such amended articles and to maintain the Company&#8217;s guarantee of FCE&#160;Ltd.&#8217;s obligations under the Series&#160;1 Preferred Shares. The articles of FCE&#160;Ltd. were amended and filed in accordance with the provisions of the January&#160;2020 Letter Agreement on March&#160;26, 2020. Under the terms of the January&#160;2020 Letter Agreement, the Company was still required to make (i)&#160;annual dividend payments of Cdn. $500,000 and (ii)&#160;annual return of capital payments of Cdn. $750,000. Dividend and return of capital payments were to be made on a quarterly basis and were scheduled to end on December&#160;31, 2021 unless these obligations were satisfied in advance of such date.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The amendment to the Series&#160;1 Preferred Shares resulted in an extinguishment of the prior Series&#160;1 Preferred Shares for accounting purposes. A revised fair value was estimated using a discounted cash flow model resulting in a revised carrying value being recorded for the amended Series&#160;1 Preferred Shares which resulted in a loss of Cdn. $0.2 million (U.S. $0.2 million) recorded in Other (expense) income, net on the Consolidated Statements of Operations and Comprehensive Loss during the three&#160;months ended January&#160;31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Prior to the amendment, the Company bifurcated embedded derivatives related to the conversion feature and a variable dividend feature. As a result of the January&#160;2020 Letter Agreement, both features were removed from the Series&#160;1 Preferred Shares which resulted in the Company recognizing a gain of U.S. $0.6 million related to the extinguishment of the embedded derivatives during the six&#160;months ended April&#160;30, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In December&#160;2020, the Company, FCE&#160;Ltd., and Enbridge entered into a payoff letter, pursuant to which the Company paid all amounts owed to Enbridge under the terms of the Series&#160;1 Preferred Shares.

Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On November&#160;30, 2020, the Company, its subsidiary guarantors, and the Orion Agent entered into a payoff letter with respect to the Orion Credit Agreement (the &#8220;Orion Payoff Letter&#8221;). Pursuant to the Orion Payoff Letter, on December&#160;7, 2020, the Company paid a total of $87.3 million to the Orion Agent, representing the outstanding principal, accrued but unpaid interest, prepayment premium, fees, costs and other expenses due and owing under the Orion Facility and the Orion Credit Agreement and related loan documents, in full repayment of the Company&#8217;s outstanding indebtedness under the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Orion Facility and the Orion Credit Agreement and related loan documents. In accordance with the Orion Payoff Letter, the aggregate prepayment premium set forth in the Orion Credit Agreement was reduced from approximately $14.9 million to $4.0 million and the Orion Agent, on behalf of itself and the lenders, agreed that any portion of the prepayment premium that would otherwise be required to be paid pursuant to the Orion Credit Agreement in excess of $4.0 million was waived by the Orion Agent and the lenders. The Company expensed the remaining deferred finance costs and debt discount of $7.1 million. The Company has classified the $4.0 million prepayment premium and the deferred finance costs and debt discount expense as Loss on extinguishment of debt on the Consolidated Statements of Operations and Comprehensive Loss.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Concurrently with the Orion Agent&#8217;s receipt of full payment pursuant to the Orion Payoff Letter, the Orion Agent released all of the collateral from the liens granted under the security documents associated with the Orion Facility (which included the release of $11.2 million of restricted cash to the Company, which became unrestricted cash), and the Company and its subsidiaries were unconditionally released from their respective obligations under the Orion Credit Agreement (and related loan documents) and the Orion Facility without further action. With the termination of the Orion Facility and the Orion Credit Agreement and related loan documents, the lenders no longer have the right to appoint representatives to attend the Company&#8217;s Board of Director meetings as observers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Liberty Bank Promissory Note</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On April&#160;20, 2020, the Company entered into the PPP Note (as defined elsewhere herein), dated April&#160;16, 2020, evidencing a loan to the Company from Liberty Bank under the CARES Act (as defined elsewhere herein), administered by the U.S. Small Business Administration. Pursuant to the PPP Note, the Company received total loan proceeds of approximately $6.5 million on April&#160;24, 2020 (the &#8220;PPP Loan&#8221;).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">As required by the Orion Agent and its affiliated lenders (collectively, &#8220;Orion&#8221;) under the Company&#8217;s (now former) senior secured credit facility, the Company applied for forgiveness of the PPP Loan in October 2020.&#160;However, with the repayment in full of all amounts owed to Orion in December 2020, the Company was no longer required to pursue forgiveness of the PPP Loan. Additionally, since the time of the application for forgiveness, the Company&#8217;s financial circumstances changed substantially, such that the Company was no longer in need of forgiveness of the PPP Loan. Accordingly, on February 11, 2021, the Company withdrew its application for forgiveness and repaid all amounts outstanding under the PPP Note.</p><span></span>

During the six&#160;months ended April&#160;30, 2021, the Company approved a sub-plan to its 2018 Omnibus Incentive Plan, as amended and restated, which is described in more detail below.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">2018 Omnibus Incentive Plan</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company&#8217;s 2018 Omnibus Incentive Plan (as amended and restated from time to time, the &#8220;2018 Incentive Plan&#8221;) authorizes grants of stock options, stock appreciation rights (&#8220;SARs&#8221;), restricted stock awards (&#8220;RSAs&#8221;), restricted stock units (&#8220;RSUs&#8221;), performance shares, performance units and incentive awards to employees, directors, consultants and advisors. Stock options, RSAs and SARs have restrictions as to transferability. Stock option exercise prices are fixed by the Company&#8217;s Board of Directors but shall not be less than the fair market value of our common stock on the date of the grant. SARs may be granted in conjunction with stock options.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On November&#160;24, 2020, the Company&#8217;s Board of Directors approved a Long Term Incentive Plan (the &#8220;LTI Plan&#8221;) as a sub-plan consisting of awards made under the 2018 Incentive Plan.&#160;The participants in the LTI Plan are members of senior management and include the Company&#8217;s named executive officers (as identified in the definitive proxy statement filed by the Company on February&#160;19, 2021). The LTI Plan consists of three award components: (1)&#160;relative total shareholder return (&#8220;TSR&#8221;) performance units, (2)&#160;absolute TSR performance units, and (3)&#160;time-vesting restricted stock units.&#160;The performance units granted during the three&#160;months ended January&#160;31, 2021 will be earned over the performance period ending on October&#160;31, 2023, but will remain subject to a continued service-based vesting requirement until the third anniversary of the date of grant.&#160;The performance measure for the relative TSR performance units is the TSR of the </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Company relative to the TSR of the Russell 2000 from November&#160;1, 2020 through October&#160;31, 2023.&#160;The performance measure for the absolute TSR performance units is an increase in the Company&#8217;s stock price during the performance period of November&#160;1, 2020 through October&#160;31, 2023.&#160;The time-vesting RSUs granted during the three&#160;months ended January&#160;31, 2021 will vest at a rate of one-third of the total number of RSUs on each of the first three anniversaries of the date of grant.&#160;None of the awards granted as part of the LTI Plan include any dividend equivalent or other stockholder rights.&#160;To the extent the awards are earned, they may be settled in shares or cash of an equivalent value at the Company&#8217;s option.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On November&#160;24, 2020, 848,078 RSUs were awarded under the LTI Plan, which include 551,252 performance units and 296,826 time-based units.

Under the terms of such service agreements, the particular power plant must meet a minimum operating output during defined periods of the term. If minimum output falls below the contract requirement, the Company may be subject to performance penalties and/or may be required to repair or replace the customer&#8217;s fuel cell module(s).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Power Purchase Agreements</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Under the terms of the Company&#8217;s PPAs, customers agree to purchase power from the Company&#8217;s fuel cell power plants at negotiated rates. Electricity rates are generally a function of the customers&#8217; current and estimated future electricity pricing available from the grid. As owner or lessee of the power plants, the Company is responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, the Company is also responsible for procuring fuel, generally natural gas or biogas, to run the power plants. In addition, under the terms of some of the PPAs, the Company may be subject to a performance penalty if the Company does not meet certain performance requirements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Other</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">As of April&#160;30, 2021, the Company had unconditional purchase commitments aggregating $73.9 million, for materials, supplies and services in the normal course of business.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Legal Proceedings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">POSCO Energy Matters</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">From approximately 2007 through 2015, we relied on POSCO Energy Co., Ltd. (&#8220;POSCO Energy&#8221;) to develop and grow the South Korean and Asian markets for our products and services. We received upfront license payments and were entitled to receive royalty income from POSCO Energy pursuant to certain manufacturing and technology transfer agreements, including the Alliance Agreement dated February&#160;7, 2007 (and the amendments thereto), the Technology Transfer, License and Distribution Agreement dated February&#160;7, 2007 (and the amendments thereto), the Stack Technology Transfer and License Agreement dated October&#160;27, 2009 (and the amendments thereto), and the Cell Technology Transfer and License Agreement dated October&#160;31, 2012 (and the amendments thereto), which are collectively referred to herein as the &#8220;License Agreements.&#8221;&#160;The License Agreements provided POSCO Energy with the exclusive technology rights to manufacture, sell, distribute and service our SureSource 300, SureSource 1500 and SureSource 3000 fuel cell technology in the South Korean and broader Asian markets. Due to certain actions and inactions of POSCO Energy, the Company has not realized any new material revenues, royalties or new projects developed by POSCO Energy since late 2015.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In November&#160;2019, POSCO Energy spun-off its fuel cell business into a new entity, Korea Fuel Cell Co.,&#160;Ltd. (&#8220;KFC&#8221;), without the Company&#8217;s consent. As part of the spin-off, POSCO Energy transferred manufacturing and service rights under the License Agreements to KFC, but retained distribution rights and severed its own liability under the License Agreements. The Company formally objected to POSCO Energy&#8217;s spin-off, and POSCO Energy posted a bond to secure any liabilities to the Company arising out of the spin-off. In September&#160;2020, the Korean Electricity Regulatory Committee found that POSCO Energy&#8217;s spin-off of the fuel cell business to KFC may have been done in violation of South Korean law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On February&#160;19, 2020, the Company notified POSCO Energy in writing that it was in material breach of the License Agreements by (i)&#160;its actions in connection with the spin-off of the fuel cell business to KFC, (ii)&#160;its suspension of performance through its cessation of all sales activities since late 2015 and its abandonment of its fuel cell business in Asia, and (iii)&#160;its disclosure of material nonpublic information to third parties and its public pronouncements about the fuel cell business on television and in print media that have caused reputational damage to the fuel cell business, the Company and its products. The Company also notified POSCO Energy that, under the terms of the License Agreements, it had 60&#160;days to fully cure its breaches to the Company&#8217;s satisfaction and that failure to so cure would lead to termination of the License Agreements. Further, on March&#160;27, 2020, the Company notified POSCO Energy of additional instances of its material breach of the License Agreements based on POSCO Energy&#8217;s failure to pay royalties required to be paid in connection with certain module exchanges.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On April&#160;27, 2020, POSCO Energy initiated a series of three arbitration demands against the Company at the International Court of Arbitration of the International Chamber of Commerce seated in Singapore alleging certain warranty defects in a sub-megawatt conditioning facility at its facility in Pohang, South Korea and seeking combined damages of approximately $3.3 million. Prior to filing the arbitrations, POSCO Energy obtained provisional attachments from the Seoul Central District Court attaching certain revenues owed to the Company by Korea Southern Power Company (&#8220;KOSPO&#8221;) as part </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">of such warranty claims, which has delayed receipt of certain payments owed to the Company. POSCO Energy subsequently sought additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on unspecified warranty claims not yet filed in an additional amount of approximately $7 million, and additional provisional attachments on KOSPO revenues from the Seoul Central District Court based on its alleged counterclaims in the license termination arbitration described below in an additional amount of approximately $110 million. As of April&#160;30, 2021, outstanding accounts receivable due from KOSPO were $8.0 million. POSCO Energy posted a bond in the amount of $46 million to secure any damages to the Company resulting from the attachments.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On June&#160;28, 2020, the Company terminated the License Agreements with POSCO Energy and filed a demand for arbitration against POSCO Energy and KFC in the International Court of Arbitration of the International Chamber of Commerce based on POSCO Energy&#8217;s (i)&#160;failure to exercise commercially reasonable efforts to sell the Company&#8217;s technology in the South Korean and Asian markets, (ii)&#160;disclosure of the Company&#8217;s proprietary information to third parties, (iii)&#160;attack on the Company&#8217;s stock price and (iv)&#160;spin-off of POSCO Energy&#8217;s fuel cell business into KFC without the Company&#8217;s consent. The Company has requested that the arbitral tribunal (a)&#160;confirm through declaration that POSCO Energy&#8217;s exclusive license to market the Company&#8217;s technology and products in South Korea and Asia is null and void as a result of the breaches of the License Agreements and that the Company has the right to pursue direct sales in these markets, (b)&#160;order POSCO Energy and KFC to compensate the Company for losses and damages suffered in the amount of more than $200 million, and (c)&#160;order POSCO Energy and KFC to pay the Company&#8217;s arbitration costs, including counsel fees and expenses. The Company has retained outside counsel on a contingency basis to pursue its claims, and outside counsel has entered into an agreement with a litigation finance provider to fund the legal fees and expenses of the arbitration. In October&#160;2020, POSCO Energy filed a counterclaim in the arbitration (x)&#160;seeking approximately $880 million in damages based on allegations that the Company misrepresented the capabilities of its fuel cell technology to induce POSCO Energy to enter into the License Agreements and failed to turn over know-how sufficient for POSCO Energy to successfully operate its business; (y)&#160;seeking a declaration that the License Agreements remain in full force and effect and requesting the arbitral tribunal enjoin the Company from interfering in POSCO Energy&#8217;s exclusive rights under the License Agreements and (z)&#160;seeking an order that the Company pay POSCO Energy&#8217;s arbitration costs, including counsel fees and expenses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company has discontinued revenue recognition of the deferred license revenue related to the terminated License Agreements given the pending arbitration and will continue to evaluate this deferred revenue in future periods.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On August&#160;28, 2020, POSCO Energy filed a complaint in the Court of Chancery of the State of Delaware (the &#8220;Court&#8221;) purportedly seeking to enforce its rights as a stockholder of the Company to inspect and make copies and extracts of certain books and records of the Company and/or the Company&#8217;s subsidiaries pursuant to Section&#160;220 of the Delaware General Corporation Law and/or Delaware common law. POSCO Energy alleges that it is seeking to inspect these documents for a proper purpose reasonably related to its interests as a stockholder of the Company, including investigating whether the Company&#8217;s Board of Directors and its management breached their fiduciary duties of loyalty, due care, and good faith. POSCO Energy seeks an order of the Court permitting POSCO Energy to inspect and copy the demanded books and records, awarding POSCO Energy reasonable costs and expenses, including reasonable attorney&#8217;s fees incurred in connection with the matter, and granting such other and further relief as the Court deems just and proper.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On September&#160;14, 2020, POSCO Energy filed a complaint in the United States District Court for the Southern District of New York alleging that the Company delayed the removal of restrictive legends on certain share certificates held by POSCO Energy in 2018, thus precluding POSCO Energy from selling the shares and resulting in claimed losses in excess of $1 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company does not believe that any of the arbitrations or legal proceedings brought against the Company by POSCO Energy are for a proper purpose. Further, the Company believes that all such arbitrations and legal proceedings are in fact simply fulfillment of POSCO Energy&#8217;s prior threats to file a series of actions against the Company and are attempts to obtain leverage over the Company and, in certain proceedings, gain advantage in the pending arbitration filed by the Company against POSCO Energy. The Company will vigorously defend itself against POSCO Energy&#8217;s claims in all forums and believes it will be apparent at the conclusion of each matter that each action was filed for an improper purpose.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 10pt 0pt;">Other Legal Proceedings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">From time to time, the Company is involved in other legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (&#8220;Other Legal Proceedings&#8221;). Although the Company cannot assure the outcome of such Other Legal Proceedings, management presently believes that the result of such Other Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company&#8217;s consolidated financial statements, and no material amounts have been accrued in the Company&#8217;s consolidated financial statements with respect to these matters.</p><span></span>

Estimates are used in accounting for, among other things, revenue recognition, contract loss accruals, excess, slow-moving and obsolete inventories, product warranty accruals, loss accruals on service agreements, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of goodwill and in-process research and development intangible assets, impairment of long-lived assets (including project assets), lease liabilities and right-of-use (&#8220;ROU&#8221;) assets, and contingencies. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary.

The Company expects to seek long-term debt and tax equity (e.g., sale-leaseback and partnership transactions) for its project asset portfolio as these projects commence commercial operations. The proceeds of any such financing, if obtained, may allow the Company to fund other projects. We may also seek to obtain additional financing in both the debt and equity markets in the future. If financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to reduce or slow planned spending, reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.</p><span></span>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame.
