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.

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.

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></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;">23</p></div></div>

(&#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 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 $<ix:nonFraction unitRef="Unit_Standard_USD_q3FmhxSKUES2SwH05XjwLA" contextRef="Duration_4_27_2020_To_4_27_2020_srt_MajorCustomersAxis_fcel_PoscoEnergyMember_FiL3-_NOUE6_H5KFgJq8bw" decimals="-5" format="ixt:numdotdecimal" name="us-gaap:LossContingencyDamagesSoughtValue" scale="6" id="Narr_kWNd6WncskytG9zfxDStVQ">3.3</ix:nonFraction> million.

POSCO Energy alleged that it was 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 right-of-use (&#8220;ROU&#8221;) 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;).

SBFC and the Company also entered into a Technology License and Access Agreement with Crestmark on August 25, 2021, which provides Crestmark with certain intellectual property license rights to have access to the Company&#8217;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the Plant in certain circumstances in which the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the Plant.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Pursuant to the Lease, SBFC has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. investment tax credit (&#8220;ITC&#8221;) anticipated to be realized by Crestmark in connection with this sale-leaseback transaction. Such obligation would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the U.S. Internal Revenue Service (&#8220;IRS&#8221;). The Company does not believe that any such obligation is probable based on the facts known as of August 25, 2021. The maximum potential future payments that SBFC could be required to make as a result of this obligation would depend on the difference between the fair value of the fuel cell project sold or financed and the value the IRS would determine as the fair value of the project for purposes of claiming the ITC. The value of the ITC in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS.

Under this partnership flip structure, a partnership, in this case Groton Station Fuel Cell Holdco, LLC (the &#8220;Partnership&#8221;) was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Groton Station Fuel Cell, LLC (the &#8220;Project Company&#8221;) which in turn owns the Groton Project and is the party to the power purchase agreement and all project agreements.

After East West Bank receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations.

The Company also commenced remote work protocol for those employees worldwide that were capable of working from home. 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. All employees that were not able to work from home during the manufacturing facility shutdown due to their job function received full wages and benefits during such time. 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. We established a phased-in return to work schedule commencing March&#160;15, 2021 for those employees working from home which was completed in April 2021, as a result of which all U.S. based employees are now back in the office. We continue to evaluate our ability to operate in the event of a resurgence 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. Given the recent increase of COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta variant, the Company has instituted policies to protect its employees and customers such as mask mandates in our facilities and a mandatory vaccination policy requiring all U.S. employees to be fully vaccinated by November 1, 2021.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:center;margin:0pt 0pt 10pt 0pt;">RESULTS OF OPERATIONS</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Management evaluates our results of operations and cash flows using a variety of key performance indicators, including revenues compared to prior periods and internal forecasts, costs of our products and results of our cost reduction initiatives, and operating cash use.

31, 2021 to $1.9 million, compared to $2.7 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 $1.7 million for the three&#160;months ended July 31, 2021 compared to approximately $2.6 million for the three&#160;months ended July 31, 2020.

The service and license revenues for the three&#160;months ended July 31, 2021 include revenues recorded for module exchanges at several plants and routine maintenance activities. The increase in revenue for the three months ended July 31, 2021 is primarily due to the fact that there were more module exchanges during the three months ended July 31, 2021 (generating approximately $13.4 million of revenue in the three months ended July 31, 2021 compared to revenue of $6.0 million in the comparable prior year period).</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 increased $4.2 million to $13.0 million for the three&#160;months ended July 31, 2021 from $8.8 million for the three&#160;months ended July 31, 2020, resulting, in part, from the fact that there were several new module exchanges in the three&#160;months ended July 31, 2021 compared to two new module exchanges in the three&#160;months ended July 31, 2020. 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 profit from service agreements and license revenues was $1.3 million for the three&#160;months ended July 31, 2021, which represents an increase of $3.0 million from a gross loss of $1.7 million for the three&#160;months ended July 31, 2020. The overall gross margin&#160;was 9.2% for the three&#160;months ended July 31, 2021 compared to a gross margin of (24.2)% in the comparable prior&#160;year period. Gross margin increased during the three&#160;months ended July 31, 2021 primarily due to more new module exchanges for projects with higher margins compared to the three months ended July 31, 2020.

$6.9 million for the three&#160;months ended July 31, 2020. Compared to the three&#160;months ended July 31, 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 $0.1 million higher during the three&#160;months ended July 31, 2021, reflecting continued performance under the EMRE Joint Development Agreement during the quarter. However, the increased revenues under the EMRE Joint Development Agreement were offset by $0.8 million less revenue recognized under government contracts during the three&#160;months ended July 31, 2021 than during the three&#160;months ended July 31, 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 were $4.1&#160;million for the three&#160;months ended July 31, 2021, compared to $4.0 million for the same period in the prior&#160;year. Advanced Technologies contracts for the three&#160;months ended July 31, 2021 generated a gross margin of $2.2 million compared to a gross margin of $2.9 million for the three&#160;months ended July 31, 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 July 31, 2021 compared to the three&#160;months ended July 31, 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 $8.7 million and $6.6&#160;million for the three&#160;months ended July 31, 2021 and 2020, respectively. The three&#160;months ended July 31, 2021 included legal expenses associated with tax equity financings (refer to Note 19. &#8220;Subsequent Events&#8221; to the Consolidated Financial Statements for more information regarding the tax equity financings) and additional expense for share-based compensation of $0.5 million due to the grants made in August&#160;2020 and November&#160;2020 under our new Long Term Incentive Plans (the &#8220;LTI Plans&#8221;) (refer to Note&#160;17. &#8220;Benefit Plans&#8221; to the Consolidated Financial Statements for more information on the November&#160;2020 grants). Also contributing to the increase in administrative and selling expenses for the three months ended July 31, 2021 was increased compensation expense as a result of an increase in staff compared to the comparable prior year period.</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 $3.0 million for the three&#160;months ended July 31, 2021 compared to $1.0 million for the three&#160;months ended July 31, 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. The comparable prior&#160;year period was impacted by restructuring initiatives implemented in 2019 and the reallocation of resources from Company-funded research and development projects 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;">Loss from operations for the three&#160;months ended July 31, 2021 was $10.6 million compared to $10.8 million for the three&#160;months ended July 31, 2020. This decrease was due to a gross profit of $1.1 million in the three months ended July 31, 2021 compared to a gross loss of $3.1 million in the three months ended July 31, 2020, offset by a $4.1 million increase in operating expenses for the three months ended July 31, 2021. As discussed above, impacting gross profit for the quarter were (i) higher service gross margin primarily due to more new module exchanges for projects with higher margins during the quarter, (ii) improved generation gross margin primarily related to an increase in revenues and a decrease in </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>

The decrease in the net loss attributable to common stockholders for the three&#160;months ended July 31, 2021 is primarily due to incurring&#160;a higher gross margin for the three months ended July 31, 2021 compared to the corresponding period in fiscal&#160;year 2020, lower interest expense during the quarter 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 July 31, 2021 offset by&#160;higher operating expenses and the fact that there was no gain on extinguishment of financing obligation recorded in the three months ended July 31, 2021. The lower loss per common share for the three&#160;months ended July 31, 2021 as compared to the three&#160;months ended July 31, 2020 is primarily due to the higher weighted average shares outstanding as of July 31, 2021 as a result of share issuances since July 31, 2020 and the lower net loss attributable to common stockholders.</p><p style="font-family:'Times New

2021 to $6.2 million, compared to $7.5 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 $5.0 million for the nine&#160;months ended July 31, 2021 compared to approximately $7.0 million for the nine&#160;months ended July 31, 2020. The decline in manufacturing variances is primarily the result of increased production volumes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">For the nine&#160;months ended July 31, 2021, we operated at an annualized production rate of approximately 30 MW, which is an increase from the annualized production rate of 14.0 MW for the nine&#160;months ended July 31, 2020. The production rate during the nine months ended July 31, 2020 was impacted by the factory shutdown in response to the COVID-19 pandemic.</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;">36</p></div></div>

license fee and royalty agreements increased marginally by $0.2 million to $19.9 million from $19.7&#160;million for the nine&#160;months ended July 31, 2020. The increase in service and license revenues for the nine&#160;months ended July 31, 2021 is primarily due to an increase in new module exchanges offset by cost estimate adjustments related to changes in the expected timing of future module exchanges. Service and license revenues for the nine&#160;months ended July 31, 2020 includes license revenues of $4.0 million associated with the EMRE Joint Development Agreement, while the nine months ended July 31, 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 $4.6 million to $21.0 million for the nine&#160;months ended July 31, 2021 from $16.4 million for the nine&#160;months ended July 31, 2020. Cost of service and license revenues were higher for the nine months ended July 31, 2021 than for the nine months ended July 31, 2020 primarily due to increases in planned maintenance activities, increased module exchanges and 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 $1.1 million for the nine&#160;months ended July 31, 2021, which represents a decrease of $4.4 million from a gross profit of $3.3 million for the nine&#160;months ended July 31, 2020. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The overall gross margin&#160;was (5.4)% for the nine&#160;months ended July 31, 2021 compared to a gross margin of 16.6% in the comparable prior&#160;year period. Gross margin decreased during the nine&#160;months ended July 31, 2021 primarily due to residual value charges for certain plants which had reached the end of their service terms and an increase in performance guarantees in the nine months ended July 31, 2021, compared to gross margin for the nine&#160;months ended July 31, 2020 which included license revenues associated with the EMRE Joint

from $19.4 million for the nine&#160;months ended July 31, 2020. Compared to the nine&#160;months ended July 31, 2020, Advanced Technologies contract revenues recognized under the EMRE Joint Development Agreement were approximately $0.8 million higher during the nine&#160;months ended July 31, 2021, reflecting continued performance under the EMRE Joint Development Agreement during the nine months ended July 31, 2021. However, the increased revenues under the EMRE Joint Development Agreement were offset by the $1.9 million less revenue recognized under government contracts during the nine&#160;months ended July 31, 2021 than during the nine&#160;months ended July 31, 2020. Cost of Advanced Technologies contract revenues increased $0.4 million to $12.5&#160;million for the nine&#160;months ended July 31, 2021, compared to $12.0 million for the same period in the prior&#160;year. Advanced Technologies contracts for the nine&#160;months ended July 31, 2021 generated a gross margin of $6.0 million compared to a gross margin of $7.3 million for the nine&#160;months ended July 31, 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 nine&#160;months ended July 31, 2021 compared to the nine&#160;months ended July 31, 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 $27.3 million and $19.0&#160;million for the nine&#160;months ended July 31, 2021 and 2020, respectively. The nine&#160;months ended July 31, 2021 included legal expenses for tax equity financings (refer to Note&#160;19. &#8220;Subsequent Events&#8221; to the Consolidated Financial Statements for more information regarding the tax equity financings), additional expense for shared-based compensation of $2.3 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), increased compensation expense and proxy mailing expenses associated with the Company&#8217;s annual stockholder meeting. The comparable prior&#160;year period also 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 $7.8 million for the nine&#160;months ended July 31, 2021 compared to $3.3 million for the nine&#160;months ended July 31, 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. The comparable prior&#160;year period was impacted by restructuring initiatives implemented in 2019 and the reallocation of resources from Company-funded research and development projects to funded Advanced Technologies projects. During the nine months ended July 31, 2021, the Company successfully commenced operation and testing of a prototype solid oxide electrolysis hydrogen platform in Danbury, Connecticut.</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;">38</p></div></div>

This increase was due to a gross loss of $7.3 million and a $12.7 million increase in operating expenses for the nine months ended July 31, 2021. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">As discussed above, impacting gross loss for the nine month period ended July 31, 2021 were (i) lower service gross margin primarily due to residual value charges for certain plants which had reached the end of their service terms and an increase in performance guarantees, whereas gross margin for the nine&#160;months ended July 31, 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 government contracts during the period. These impacts were partially offset by lower manufacturing variances primarily resulting from increased production volumes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></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 nine&#160;months ended July 31, 2021. Administrative and selling expenses included legal expenses for tax equity financings, additional share-based compensation expense under the LTI Plans, 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 nine months ended July 31, 2020 included a $2.2 million legal settlement that offset administrative and selling expenses and there was no comparable gain for the nine months ended July 31, 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 0pt 10pt 0pt;">Interest expense for the nine&#160;months ended July 31, 2021 and 2020 was $5.7 million and $11.0 million, respectively. Interest expense for both periods presented includes interest related to sale-leaseback transactions and on the loans outstanding associated with the Bridgeport Fuel Cell Project. Interest expense for both periods also includes interest for the amortization of the redeemable preferred stock of subsidiary fair value discount. Amounts owed pursuant to the terms of the redeemable preferred stock issued by FCE Ltd. (which is referred to elsewhere herein as the Series 1 Preferred Shares) were paid, in full, in December&#160;2020. The decrease in interest expense for the nine&#160;months ended July 31, 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;">Loss (gain) on extinguishment of debt and financing obligation</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.13;text-align:justify;margin:6pt 0pt 0pt 0pt;">The loss on extinguishment of debt for the nine months ended July 31, 2021 represents costs associated with the repayment of the $80.0 million principal balance outstanding under the Orion Credit Agreement. The loss on extinguishment of debt amount includes an early prepayment penalty of $4.0 million and the write-off of unamortized debt discounts and deferred finance costs of $7.1 million.

The increase in the net loss attributable to common stockholders for the nine&#160;months ended July 31, 2021 is primarily due to incurring (i)&#160;a gross loss for the period compared to a gross profit for the corresponding period in fiscal&#160;year 2020, (ii)&#160;higher operating expenses for the period, (iii)&#160;an $11.2 million loss recorded on the extinguishment of the Orion Facility, and (iv)&#160;a $0.9 million charge for the extinguishment of the Series 1 Preferred Share obligation. These amounts were offset by lower interest expense due to repayment of the Orion Facility and a lower charge for the change in fair value of common stock warrant liability. The net loss attributable to common stockholders for the nine-months ended July 31, 2020 reflected a $1.8 million gain on the extinguishment of a financing obligation. &#160;There was no comparable gain recorded in the nine-months ended July 31, 2021. The lower loss per common share for the nine&#160;months ended July 31, 2021 as compared to the nine&#160;months ended July 31, 2020 is due to the higher weighted average shares outstanding as of July 31, 2021 as a result of share issuances since July 31, 2020.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:center;margin:0pt 0pt 10pt 0pt;">LIQUIDITY AND CAPITAL RESOURCES</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Overview, Cash Position, Sources and Uses</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, 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.

From the date of the Open Market Sale Agreement through July 31, 2021, approximately 44.0 million shares were sold resulting in net proceeds to the Company totaling approximately $369.0 million. Subsequent to July 31, 2021, an additional 0.9 million shares were sold resulting in net proceeds of approximately $0.6 million. The remaining availability under the Open Market Sale Agreement as of the date of filing of this report is approximately $122.8 million. The Company plans to use the net proceeds from this offering to accelerate the development and commercialization of our Advanced Technologies products, including our solid oxide platform, for project development, for internal research and development, to invest in capacity expansion for solid oxide and carbonate fuel cell manufacturing, and for project financing, working capital support, and general corporate purposes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="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;">We believe that our unrestricted cash and cash equivalents, expected receipts from our contracted backlog, and release of short-term restricted cash less expected disbursements over the next twelve&#160;months will be sufficient to allow the Company&#160;to&#160;meet its obligations for at least one&#160;year from the date of issuance of these financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">To date, we have not achieved profitable operations or sustained positive cash flow from operations.

Therefore, from time to time, the Company may consider 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. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Generation/Operating Portfolio, Projects, and Backlog</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">To grow our generation portfolio, the Company will invest in developing and building turn-key fuel cell projects which will be owned by the Company and classified as project assets on the balance sheet. 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 (34.0 MW as of July 31, 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 July 31, 2021, the Company had projects representing an additional 42.1 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 0pt 10pt 0pt;">As of July 31, 2021, net debt outstanding related to project assets was $67.8 million. Future required payments totaled $40.3 million as of July 31, 2021. The outstanding financing obligations under our sale-leaseback transactions, which totaled $48.6 million as of July 31, 2021, include an embedded gain of $31.4 million, which will be recognized at the end of the applicable lease terms. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Our operating portfolio provides us with the full benefit of future cash flows, net of any debt service requirements.</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;">42</p></div></div>

Our team has identified the root cause of the issue and is in the process of applying improvements and preventative upgrades as well as making the necessary repairs to the plant. The issue identified affects unique aspects of this plant and does not affect the rest of our fleet.

East West Bank&#8217;s tax equity commitment totals $15 million. In connection with the initial closing, the Company was able to draw down $3.0 million, of which approximately $0.8 million was used to pay closing costs including appraisal fees, title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation.

production levels, leading to lower costs on a per unit basis. We also continue to invest in new product and market development and, as a result, we are not generating positive cash flow from our operations. Our operations are funded primarily through cash generated from product sales, service contracts, generation assets and Advanced Technologies contracts, as well as sales of equity and equity linked securities, issuances of corporate and project level debt, and monetization of technology through licenses.</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>

In addition to the cash interest, payment-in-kind interest of&#160;2.05% per annum accrued which was added to the outstanding principal balance of the Orion Facility but was paid quarterly in cash to the extent of available cash after payment of the Company&#8217;s operating expenses and the funding of certain reserves for the payment of outstanding indebtedness to the State of Connecticut and Connecticut Green Bank.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">Outstanding principal under the Orion Facility was to be amortized on a straight-line basis over a&#160;seven-year&#160;term, with the initial payment due 21 business&#160;days after the end of the first quarter of fiscal&#160;year 2021. The maturity date of the Orion Facility was&#160;October&#160;31, 2027. The Orion Facility contained an administrative fee of $0.1&#160;million per&#160;year paid on a quarterly basis and also included a prepayment premium of up to&#160;35%. Such prepayment fee was to be reduced over time based on the aggregate amount of principal and interest paid.</p><p style="font-family:'Times New 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 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 </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>

On and effective as of December&#160;19, 2019, the Company and Connecticut Green Bank entered into an amendment to the Green Bank Loan Agreement (the &#8220;Green Bank Amendment&#8221;). Upon the execution of the Green Bank Amendment on December&#160;19, 2019, Connecticut Green Bank made an additional loan to the Company in the aggregate principal amount of $3.0 million (the &#8220;December&#160;2019 Loan&#8221;), which was to be used (i)&#160;first, to pay closing fees related to the May&#160;9, 2019 acquisition of the Bridgeport Fuel Cell Project and the Subordinated Credit Agreement (as defined below), other fees and interest, and (ii)&#160;thereafter, for general corporate purposes.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Green Bank Amendment provides that, until such time as the loan (which includes both the outstanding principal balance of the original loan under the Green Bank Loan Agreement and the outstanding principal amount of the December&#160;2019 Loan) has been repaid in its entirety, interest on the outstanding balance of the loan shall accrue at a rate of 8% per annum, payable by the Company on a&#160;monthly basis in arrears. Interest payments made by the Company after the date of the Green Bank Amendment are to be applied first to interest that has accrued on the outstanding principal balance of the original loan under the Green Bank Loan Agreement and then to interest that has accrued on the December&#160;2019 Loan.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Green Bank Amendment also modifies the repayment and mandatory prepayment terms and extends the maturity date set forth in the original Green Bank Loan Agreement. Under the Green Bank Amendment, to the extent that excess cash flow reserve funds under the BFC Credit Agreement (as defined below) are eligible for disbursement to Bridgeport Fuel Cell, LLC pursuant to Section&#160;6.23(c)&#160;of the BFC Credit Agreement, such funds are to be paid to Connecticut Green Bank until the loans are repaid in full. The Green Bank Amendment further provides that any unpaid balance of the loan and all other obligations due under the Green Bank Loan Agreement will be due and payable on May&#160;9, 2026. Finally, with respect to mandatory prepayments, the Green Bank Amendment provides that, when the Company has closed on the subordinated project term loan pursuant to the Commitment Letter, dated February&#160;6, 2019, issued by Connecticut Green Bank to Groton Station Fuel Cell, LLC (&#8220;Groton Fuel Cell&#8221;) to provide a subordinated project term loan to Groton Fuel Cell in the amount of $5.0 million, the Company will be required to prepay to Connecticut Green Bank the lesser of any then outstanding amount of the December&#160;2019 Loan and the amount of the subordinated project term loan actually advanced by Connecticut Green Bank. The balance under the original Green Bank Loan Agreement and the December&#160;2019 Loan as of July 31, 2021 was $4.8 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Bridgeport Fuel Cell Project Loans</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On May&#160;9, 2019, in connection with the closing of the purchase of the membership interests of Bridgeport Fuel Cell, LLC (&#8220;BFC&#8221;) (and the 14.9 MW Bridgeport Fuel Cell Project), BFC entered into a subordinated credit agreement with the Connecticut Green Bank whereby Connecticut Green Bank provided financing in the amount of $6.0 million (the &#8220;Subordinated Credit Agreement&#8221;). This $6.0 million consisted of $1.8 million in incremental funding that was received by BFC and $4.2 million of funding previously received by FuelCell Energy,&#160;Inc. with respect to which BFC became the primary obligor.

The interest rate under the Subordinated Credit Agreement is 8% per annum. Principal and interest are due&#160;monthly in amounts sufficient to fully amortize the loan over an 84-month period ending in May&#160;2026. The Subordinated Credit Agreement contains customary representations, warranties and covenants. The Subordinated Credit Agreement contains a debt coverage ratio which is required to be maintained and may not be less than&#160;1.10&#160;as of the end of each fiscal quarter, beginning with the quarter ended July&#160;31, 2020. The balance under the Subordinated Credit Agreement as of July 31, 2021 was $4.5 million.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">On May&#160;9, 2019, in connection with the closing of the purchase of the Bridgeport Fuel Cell Project, BFC entered into a Credit Agreement with Liberty Bank, as administrative agent and co-lead arranger, and Fifth Third Bank as co-lead arranger and swap hedger (the &#8220;BFC Credit Agreement&#8221;), whereby (i)&#160;Fifth Third Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition; and (ii)&#160;Liberty Bank provided financing in the amount of $12.5 million towards the purchase price for the BFC acquisition. As security for the BFC Credit Agreement, Liberty Bank and Fifth Third Bank were granted a first priority lien in (i)&#160;all assets of BFC, including BFC&#8217;s cash accounts, fuel cells, and all other personal property, as well as third party contracts including the Energy Purchase Agreement between BFC and Connecticut Light and Power Company dated July&#160;10, 2009, as amended; (ii)&#160;certain fuel cell modules that are intended to be used to replace the Bridgeport Fuel Cell Project&#8217;s fuel cell modules as part of routine operation and maintenance; and (iii)&#160; FuelCell Finance (a wholly-owned subsidiary of the Company and the direct parent of BFC) ownership interest in BFC. The maturity date under the BFC Credit Agreement is May&#160;9, 2025.&#160;Monthly principal and interest are to be paid in arrears in an amount sufficient to fully amortize the term loan over a 72-month period. BFC has the right to make additional principal payments or pay the balance due under the BFC Credit Agreement in full, provided that it pays any associated breakage fees with regard to the interest rate swap agreements fixing the interest rate. The interest rate under the BFC Credit Agreement fluctuates&#160;monthly at the 30-day LIBOR rate plus 275 basis points.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">An interest rate swap agreement was required to be entered into with Fifth Third Bank in connection with the BFC Credit Agreement to protect against movements in the floating LIBOR index. 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. The fair value adjustments for the three&#160;months ended July 31, 2021 and 2020 resulted in a $0.1 million gain and a $0.04 million charge, respectively, and for the nine&#160;months ended July 31, 2021 and 2020 resulted in a $0.3 million gain and a $0.04 million charge, respectively. The fair value of the interest rate swap liability at July 31, 2021 and October&#160;31, 2020 was $0.6 million and $0.9 million, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The BFC Credit Agreement requires BFC to maintain a debt service reserve. Each of Liberty Bank and Fifth Third Bank also has an operation and module exchange reserve (&#8220;O&amp;M Reserve&#8221;) under the BFC Credit Agreement. BFC is required to deposit $100,000 per&#160;month into each O&amp;M Reserve for the first five&#160;years of the BFC Credit Agreement, with such funds to be released at the sole discretion of Liberty Bank and Fifth Third Bank, as applicable. 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;">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 </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;">51</p></div></div>

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 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 first to accelerate the payment of any outstanding fees or interest due and then to accelerate the payment of outstanding principal.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In April&#160;of 2020, as a result of the COVID-19 pandemic, the State of Connecticut agreed to defer&#160;three&#160;months&#160;of principal and interest payments under the Assistance Agreement, beginning with the May&#160;2020 payment.

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 July 31, 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></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>

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 0pt 10pt 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 July 31, 2021 and 2020 resulted in a gain of $0.1 million and a charge of $0.04 million, respectively, and for the nine&#160;months ended July 31, 2021 and 2020 resulted in a gain of $0.3 million and a charge of $0.5 million, respectively.</p><a id="_4fd8efff_38bf_4958_b9ef_3ccfca20e6b5"></a><a id="Item4CONTROLSANDPROCEDURES_379212"></a><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Item&#160;4.&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;CONTROLS AND PROCEDURES</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The Company maintains disclosure controls and procedures, which are designed to provide reasonable assurance that information required to be disclosed in the Company&#8217;s periodic SEC reports is recorded, processed, summarized and reported within the time periods specified in the SEC&#8217;s rules&#160;and forms, and that such information is accumulated and communicated to its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We carried out an evaluation, under the supervision and with the participation of our principal executive officer and principal financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report.

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. As of July 31, 2021, outstanding accounts receivable due from KOSPO were $9.6 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;">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 </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;">55</p></div></div>

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;">In July 2020, the Company 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 alleged that it was 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 sought 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. &#160;On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#8217;s demand to inspect the Company&#8217;s books and records because POSCO Energy lacked a proper purpose. &#160;The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#8217;s purpose in initiating the books and records demand and filing the complaint was not 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 continues to vigorously defend itself against POSCO Energy&#8217;s claims in all forums and believes, as was the case with POSCO Energy&#8217;s books and records demand, that 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;">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. For example, given the recent increase of COVID-19 cases throughout the U.S. as a result of the highly transmissible Delta variant, the Company has instituted policies to protect its employees and customers such as mask mandates in our facilities and a mandatory vaccination policy requiring all U.S. employees to be fully vaccinated by November 1, 2021. &#160;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 </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;">57</p></div></div>

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 recession that has occurred or may occur in the future because of the pandemic, or because the pandemic worsens again. 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></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;">58</p></div></div>

provided that the determination as to the amount or number of shares subject to any long-term incentive awards, and the other terms and conditions of such awards, shall be subject to the sole discretion of the Board or a committee thereof. &#160;For such period that you served as Interim General Counsel until the date of your removal and redesignation as Vice President, Associate General Counsel your target bonus for such fiscal year will be determined by applying (a) a rate of 55% to your earned base salary for such part of the fiscal year that you acted as Interim General Counsel and Corporate Secretary and (b) a rate of 30% to your earned base salary as Vice President, Associate General Counsel for the remainder of such fiscal year, provided that the actual amount of the bonus may be more or less than the target amount, and may be pro rated for any partial year of service. &#160;If such removal and redesignation occurs, then this Agreement will immediately terminate upon such removal and redesignation and your base salary, bonus target and benefits will revert to the levels set forth above. &#160;For the avoidance of doubt, notwithstanding anything to the contrary herein, your removal from the role of Interim General Counsel and Corporate Secretary and redesignation to the role of Vice President, Associate General Counsel, including the related diminutions, shall not constitute Good Reason under this Agreement or under any other compensation plan or arrangement of the Corporation or entitle you, alone or in combination with any other event, to any benefits hereunder or under any other compensation plan or arrangement of the Corporation. &#160;Such removal and redesignation also shall not be deemed a termination of your employment or service with the Corporation and its affiliates for any purpose. &#160;Nothing in this Agreement, however, shall entitle you to continued employment or service with the Corporation and its affiliates. &#160;This Agreement contains the entire understanding of the parties hereto with respect to the subject matter hereof and supersedes any other employment agreement or similar arrangement you may have with the Corporation.</p><table border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:12pt;margin-bottom:12pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="font-family:'Times New Roman';font-size:12pt;text-transform:none;vertical-align:baseline;white-space:nowrap;width:36pt;padding:0pt;">VI.</td><td style="padding:0pt;"><u style="font-family:'Times New Roman','Times','serif';font-size:12pt;font-style:normal;font-weight:normal;text-align:justify;text-decoration:underline;text-decoration-color:#000000;">Compliance with Section 409A of the Code</u><font style="font-family:'Times New Roman','Times','serif';font-size:12pt;font-style:normal;font-weight:normal;text-align:justify;">.</font></td></tr></table><p style="font-family:'Times New Roman','Times','serif';font-size:12pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">To the extent the Corporation in the exercise of its reasonable judgment shall determine that Section 409A of the Internal Revenue Code of 1986, as amended (the &#8220;Code&#8221;) applies to any amounts payable to you hereunder, then any such amounts shall be paid in such fashion and at such times so as to ensure that the Corporation and you are in compliance with Section 409A of the Code;

Accordingly, they do not contain all of the information and footnotes required by accounting principles generally accepted in the United States of America (&#x201c;GAAP&#x201d;) for complete financial statements. In the opinion of management, all normal and recurring adjustments necessary to fairly present the Company&#x2019;s financial position and results of operations as of and for the three and nine&#160;months ended July 31, 2021 and 2020 have been included.

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 (&#x201c;ROU&#x201d;) 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.&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;Liquidity&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 principal sources of cash have been sales of our common stock through public equity offerings, proceeds from third party debt, 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&#x2019;s future liquidity will depend on its ability to (i)&#160;timely complete current projects in process within budget, (ii)&#160;increase cash flows from its generation portfolio, including by meeting conditions required to timely commence operation of new projects, operating its generation portfolio in compliance with minimum performance guarantees and operating its &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;generation portfolio in accordance with revenue expectations, (iii)&#160;obtain financing for project construction, (iv)&#160;obtain permanent financing for its projects once constructed, (v)&#160;increase order and contract volumes, which would lead to additional product sales, service agreements and generation revenues, (vi)&#160;obtain funding for and receive payment for research and development under current and future Advanced Technologies contracts, (vii) successfully commercialize its Advanced Technologies platforms, including its solid oxide, hydrogen and carbon capture platforms, (viii)&#160;implement the product cost reductions necessary to achieve profitable operations, (ix)&#160;manage working capital and the Company&#x2019;s unrestricted cash balance&#160;and (x)&#160;access the capital markets to raise funds through the sale of equity securities, convertible notes, and other equity-linked instruments.&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;We are continually assessing different means by which to accelerate the Company&#x2019;s growth, enter new markets, commercialize new products, and enable capacity expansion. Therefore, from time to time, the Company may consider 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;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

Therefore, from time to time, the Company may consider 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>

These amounts are included on a separate line item as Unbilled receivables for amounts expected to be billed within one year from the balance sheet date, 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.

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. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin: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 &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;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. The Company does 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 July 31, 2021 and 2020 was $0.4 million and $0.2 million, respectively, and for the nine&#160;months ended July 31, 2021 and 2020 was $1.1 million and $0.5 million, respectively. As of July 31, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20&#160;years and the weighted average discount rate was 7.9%. Lease payments made during the three&#160;months ended July 31, 2021 and 2020 were $0.3 million and $0.2 million, respectively, and during the nine months ended July 31, 2021 and 2020 were $0.9 million and $0.7 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

In addition, under the Orion Credit Agreement, on November&#160;22, 2019, the date on which the Company made a second draw of $65.5 million under the Orion Credit Agreement (the &#x201c;Second Funding&#x201d;), the Company issued warrants to the lenders under the Orion Credit Agreement to purchase up to a total of 14,000,000 shares of the Company&#x2019;s common stock, with an exercise price with respect to 8,000,000 of such shares of $0.242 per share and with an exercise price with respect to 6,000,000 of such shares of $0.62 per share (the &#x201c;Second Funding Warrants&#x201d;, and together with the Initial Funding Warrants, the &#x201c;Orion Warrants&#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;During the three&#160;months ended January&#160;31, 2020, the lenders exercised, on a cashless basis, Orion Warrants representing the right to purchase 12,000,000 shares of the Company&#x2019;s common stock. 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 July 31, 2020 based upon a volatility of 111.97%, a risk free rate of 0.39% and the Company&#x2019;s common stock price at July 31, 2020 of $2.23 per share, which resulted in a charge for the three months ended July 31, 2020 of $1.7 million. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin: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 &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;2,700,000 shares of the Company&#x2019;s common stock for an aggregate exercise price of approximately $0.6 million (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 nine months ended July 31, 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. There were no warrants exercised during the three months ended July 31, 2021.

(&#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 $1.8 million during the three-month and nine-month periods ended July 31, 2020, respectively. The Company&#x2019;s payments made during the nine-months ended July 31, 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. $1.1 million for the three months ended July 31, 2020 and Cdn. $0.6 million and Cdn. $2.9 million for the nine&#160;months ended July 31, 2021 and 2020, respectively. There was no interest expense recorded for the three months ended July 31, 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 income (expense), 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 nine months ended July 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;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 0pt 10pt 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 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 and financing obligation 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>

Benefit Plans&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;We have stockholder approved equity incentive plans, a stockholder approved Employee Stock Purchase Plan and an employee tax-deferred savings plan. During the nine&#160;months ended July 31, 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, RSUs 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 0pt 10pt 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 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 was $14.41 per share and the estimated fair value of the 275,626 absolute TSR performance units was $15.36 per share. The performance units and time-based units are 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;"&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 &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;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 style="font-family:'Times New

(&#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 0pt 10pt 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 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 July 31, 2021, outstanding accounts receivable due from KOSPO were $9.6 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;"&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 &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;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;In July 2020, the Company 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 alleged that it was 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 sought 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. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#x2019;s demand to inspect the Company&#x2019;s books and records because POSCO Energy lacked a proper purpose. &#160;The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#x2019;s purpose in initiating the books and records demand and filing the complaint was not 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.

Under these agreements, SBFC sold the 1.4 megawatt (&#x201c;MW&#x201d;) biogas fueled fuel cell power plant (the &#x201c;Plant&#x201d;) located at the San Bernardino wastewater treatment plant in San Bernardino, California to Crestmark for a purchase price of $10.2 million and then leased the Plant back from Crestmark. SBFC sells the power produced by the Plant to a third party under a twenty-year PPA (the &#x201c;San Bernardino PPA&#x201d;). &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"&gt;The Lease has an initial term of ten years but may be extended at the option of SBFC. An initial rental down payment and one quarter&#x2019;s rent totaling $2.2 million was paid using the proceeds from the sale of the Plant. Lease payments are expected to be funded with proceeds from the sale of power under the San Bernardino PPA on a quarterly basis. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"&gt;Reserves covering debt service and future module replacement totaling $2.5 million were also deducted from the proceeds from the sale of the Plant and will be classified as restricted cash of the Company until such time as it meets its performance obligations (such as servicing the Plant and providing module replacements) under the Long Term Service Agreement for the Plant. The Company&#x2019;s net unrestricted cash proceeds from the transaction totaled approximately $5.3 million, which is the purchase price less the initial rent payments, debt and module reserves, and taxes and transaction fees. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;In addition, SBFC and Crestmark entered into an Assignment Agreement on August 25, 2021 (the &#x201c;Assignment Agreement&#x201d;) and FuelCell Energy Finance, LLC (&#x201c;FuelCell Finance&#x201d;, a wholly-owned subsidiary of the Company and the direct parent of SBFC) and Crestmark entered into a Pledge Agreement on August 25, 2021 (the &#x201c;Pledge Agreement&#x201d;) pursuant to which agreements collateral was provided to Crestmark to secure SBFC&#x2019;s obligations under the Lease which includes a security interest in (i) certain agreements relating to the sale-leaseback transaction, (ii) the revenues with respect to the Plant, (iii) a cash module replacement reserve for the Plant, and (iv) FuelCell Finance&#x2019;s equity interest in SBFC. SBFC and the Company also entered into a Technology License and Access Agreement with Crestmark on August 25, 2021, which provides Crestmark with certain intellectual property license rights to have access to the Company&#x2019;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the Plant in certain circumstances in which the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the Plant.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Pursuant to the Lease, SBFC has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. investment tax credit (&#x201c;ITC&#x201d;) anticipated to be realized by Crestmark in connection with this sale-leaseback transaction. Such obligation would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the U.S. Internal Revenue Service (&#x201c;IRS&#x201d;). The Company does not believe that any such obligation is probable based on the facts known as of August 25, 2021. The maximum potential future payments that SBFC could be required to make as a result of this obligation would depend on the difference between the fair value of the fuel cell project sold or financed and the value the IRS would determine as the fair value of the project for purposes of claiming the ITC. The value of the ITC in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS. The Company and Crestmark used a fair value determined with the assistance of an independent third-party appraisal.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The Purchase Agreement and the Lease contain representations and warranties, affirmative and negative covenants, and events of default that entitle Crestmark to cause SBFC&#x2019;s indebtedness under the Lease to become immediately due and payable. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Pursuant to a Guaranty Agreement executed on August 25, 2021 by the Company for the benefit of Crestmark (the &#x201c;Guaranty&#x201d;), the Company has guaranteed the payment and performance of SBFC&#x2019;s obligations under the Lease.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="font-size:12pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;i style="font-style:italic;"&gt;East West Bank Tax Equity Financing Transaction&lt;/i&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:10pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;The Company closed on a tax equity financing transaction in August 2021 with East West Bancorp, Inc. (&#x201c;East West Bank&#x201d;) for the 7.4 MW fuel cell project (the &#x201c;Groton Project&#x201d;) located on the U.S. Navy Submarine Base in Groton, CT, also known as the Submarine Force. East West Bank&#x2019;s tax equity commitment totals $15 million (the &#x201c;Purchase Price&#x201d;).&#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:10pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;This transaction was structured as a "partnership flip," which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case Groton Station Fuel Cell Holdco, LLC (the &#x201c;Partnership&#x201d;) was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Groton Station Fuel Cell, LLC (the &#x201c;Project Company&#x201d;) which in turn owns the Groton Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Partnership is owned by East West Bank, holding Class A Units and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. &#160;The acquisition of the Project Company by the Partnership was funded in part by an initial draw from East West Bank and funds contributed downstream to the Partnership by the Company. The initial closing occurred on August 4, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the Groton Project would be eligible for the ITC under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down $3.0 million, of which approximately $0.8 million was used to pay closing costs including appraisal fees, title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="margin-bottom:10pt;visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Under a partnership flip structure, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, East West Bank will receive substantially all of the non-cash value attributable to the Groton Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the Groton Project), which are paid quarterly. After East West Bank receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Partnership to service the debt. &#160;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;&lt;span style="visibility:hidden;"&gt;&#x200b;&lt;/span&gt;&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;Under this partnership flip structure, we have an option to acquire all of the equity interests that East West Bank holds in the Partnership starting approximately five and a half years (the anticipated &#x201c;flip&#x201d; date) after the Groton Project is operational. If we exercise this option, we are required to pay the greater of the following: (i) the fair market value of East West Bank's equity interest at the time the option is exercised, (ii) 5% of the Purchase Price or (iii) East West Bank&#x2019;s claim in liquidation determined using the hypothetical liquidation at book value method. &lt;/p&gt;</us-gaap:SubsequentEventsTextBlock>

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. Founded in 1969, FuelCell Energy is a manufacturer of clean fuel cell power platforms delivering power and thermal energy and capable of delivering hydrogen, long-duration hydrogen energy storage, and carbon capture applications.

Our leading geographic markets are currently the United States and South Korea, and we are pursuing opportunities in other countries around the world.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;margin:0pt 0pt 10pt 0pt;">Basis of Presentation</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules&#160;and regulations of the Securities and Exchange Commission (&#8220;SEC&#8221;) regarding interim financial information. 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 nine&#160;months ended July 31, 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, 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.

From the date of the Open Market Sale Agreement through July 31, 2021, approximately 44.0 million shares were sold resulting in net proceeds to the Company totaling approximately $369.0 million. The Company plans to use the net proceeds from this offering to accelerate the development and commercialization of our Advanced Technologies products, including our solid oxide platform, for project development, for internal research and development, to invest in capacity expansion for solid oxide and carbonate fuel cell manufacturing, and for project financing, working capital support, and general corporate purposes. See Note 12. &#8220;Stockholders&#8217; Equity and Warrant Liabilities&#8221; for additional information regarding the Open Market Sale Agreement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">We believe that our unrestricted cash and cash equivalents, expected receipts from our contracted backlog, and release of short-term restricted cash less expected disbursements over the next twelve&#160;months will be sufficient to allow the Company&#160;to&#160;meet its obligations for at least one&#160;year from the date of issuance of these financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">To date, we have not achieved profitable operations or sustained positive cash flow from operations. The Company&#8217;s future liquidity will depend on its ability to (i)&#160;timely complete current projects in process within budget, (ii)&#160;increase cash flows from its generation portfolio, including by meeting conditions required to timely commence operation of new projects, operating its generation portfolio in compliance with minimum performance guarantees and operating its </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">generation portfolio in accordance with revenue expectations, (iii)&#160;obtain financing for project construction, (iv)&#160;obtain permanent financing for its projects once constructed, (v)&#160;increase order and contract volumes, which would lead to additional product sales, service agreements and generation revenues, (vi)&#160;obtain funding for and receive payment for research and development under current and future Advanced Technologies contracts, (vii) successfully commercialize its Advanced Technologies platforms, including its solid oxide, hydrogen and carbon capture platforms, (viii)&#160;implement the product cost reductions necessary to achieve profitable operations, (ix)&#160;manage working capital and the Company&#8217;s unrestricted cash balance&#160;and (x)&#160;access the capital markets to raise funds through the sale of equity securities, convertible notes, and other equity-linked instruments.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">We are continually assessing different means by which to accelerate the Company&#8217;s growth, enter new markets, commercialize new products, and enable capacity expansion. Therefore, from time to time, the Company may consider 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. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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.</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 for amounts expected to be billed within one year from the balance sheet date, 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;">Contract liabilities as of July 31, 2021 and October&#160;31, 2020 were $37.4 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. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">In July 2020, the Company 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 July 31, 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 0pt 10pt 0pt;">Remaining performance obligations are the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of July 31, 2021, the Company&#8217;s total remaining performance obligations were: $127.0 million for service agreements, $22.2 million for license agreements and $40.0 million for Advanced Technologies contracts in 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>

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. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin: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 </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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. The Company does 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 July 31, 2021 and 2020 was $0.4 million and $0.2 million, respectively, and for the nine&#160;months ended July 31, 2021 and 2020 was $1.1 million and $0.5 million, respectively. As of July 31, 2021, the weighted average remaining lease term (in&#160;years) was approximately 20&#160;years and the weighted average discount rate was 7.9%. Lease payments made during the three&#160;months ended July 31, 2021 and 2020 were $0.3 million and $0.2 million, respectively, and during the nine months ended July 31, 2021 and 2020 were $0.9

In addition, under the Orion Credit Agreement, on November&#160;22, 2019, the date on which the Company made a second draw of $65.5 million under the Orion Credit Agreement (the &#8220;Second Funding&#8221;), the Company issued warrants to the lenders under the Orion Credit Agreement to purchase up to a total of 14,000,000 shares of the Company&#8217;s common stock, with an exercise price with respect to 8,000,000 of such shares of $0.242 per share and with an exercise price with respect to 6,000,000 of such shares of $0.62 per share (the &#8220;Second Funding Warrants&#8221;, and together with the Initial Funding Warrants, the &#8220;Orion Warrants&#8221;). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">During the three&#160;months ended January&#160;31, 2020, the lenders exercised, on a cashless basis, Orion Warrants representing the right to purchase 12,000,000 shares of the Company&#8217;s common stock. 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 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&#8217;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&#8217;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 July 31, 2020 based upon a volatility of 111.97%, a risk free rate of 0.39% and the Company&#8217;s common stock price at July 31, 2020 of $2.23 per share, which resulted in a charge for the three months ended July 31, 2020 of $1.7 million. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">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.

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 income (expense), 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 nine months ended July 31, 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. 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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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.</p><span></span>

Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 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 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 and financing obligation 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 nine&#160;months ended July 31, 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, RSUs 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 0pt 10pt 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 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. Should the Company&#8217;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 was $14.41 per share and the estimated fair value of the 275,626 absolute TSR performance units was $15.36 per share. The performance units and time-based units are expensed over the three-year service period.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">On April 8, 2021, the Company&#8217;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&#8217;s common stock.

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 July 31, 2021, the Company had unconditional purchase commitments aggregating $78.1 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 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. As of July 31, 2021, outstanding accounts receivable due from KOSPO were $9.6 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;">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 </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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;">In July 2020, the Company 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 alleged that it was 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 sought 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. On July 9, 2021, the Court issued a post-trial ruling denying POSCO Energy&#8217;s demand to inspect the Company&#8217;s books and records because POSCO Energy lacked a proper purpose. &#160;The Court held that the totality of the circumstances, including the fact that this complaint was the seventh legal action POSCO Energy initiated against the Company within the span of nine months, confirmed that POSCO Energy&#8217;s purpose in initiating the books and records demand and filing the complaint was not 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 continues to vigorously defend itself against POSCO Energy&#8217;s claims in all forums and believes, as was the case with POSCO Energy&#8217;s books and records demand, that 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;">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 </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 0pt;">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>

Under these agreements, SBFC sold the 1.4 megawatt (&#8220;MW&#8221;) biogas fueled fuel cell power plant (the &#8220;Plant&#8221;) located at the San Bernardino wastewater treatment plant in San Bernardino, California to Crestmark for a purchase price of $10.2 million and then leased the Plant back from Crestmark. SBFC sells the power produced by the Plant to a third party under a twenty-year PPA (the &#8220;San Bernardino PPA&#8221;). </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;">The Lease has an initial term of ten years but may be extended at the option of SBFC. An initial rental down payment and one quarter&#8217;s rent totaling $2.2 million was paid using the proceeds from the sale of the Plant. Lease payments are expected to be funded with proceeds from the sale of power under the San Bernardino PPA on a quarterly basis. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;">Reserves covering debt service and future module replacement totaling $2.5 million were also deducted from the proceeds from the sale of the Plant and will be classified as restricted cash of the Company until such time as it meets its performance obligations (such as servicing the Plant and providing module replacements) under the Long Term Service Agreement for the Plant. The Company&#8217;s net unrestricted cash proceeds from the transaction totaled approximately $5.3 million, which is the purchase price less the initial rent payments, debt and module reserves, and taxes and transaction fees. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.14;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">In addition, SBFC and Crestmark entered into an Assignment Agreement on August 25, 2021 (the &#8220;Assignment Agreement&#8221;) and FuelCell Energy Finance, LLC (&#8220;FuelCell Finance&#8221;, a wholly-owned subsidiary of the Company and the direct parent of SBFC) and Crestmark entered into a Pledge Agreement on August 25, 2021 (the &#8220;Pledge Agreement&#8221;) pursuant to which agreements collateral was provided to Crestmark to secure SBFC&#8217;s obligations under the Lease which includes a security interest in (i) certain agreements relating to the sale-leaseback transaction, (ii) the revenues with respect to the Plant, (iii) a cash module replacement reserve for the Plant, and (iv) FuelCell Finance&#8217;s equity interest in SBFC. SBFC and the Company also entered into a Technology License and Access Agreement with Crestmark on August 25, 2021, which provides Crestmark with certain intellectual property license rights to have access to the Company&#8217;s proprietary fuel cell technology, but only for the purpose of maintaining and servicing the Plant in certain circumstances in which the Company is not satisfying its obligations under its service agreement with regard to the maintenance and servicing of the Plant.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Pursuant to the Lease, SBFC has an obligation to indemnify Crestmark for the amount of any actual reduction in the U.S. investment tax credit (&#8220;ITC&#8221;) anticipated to be realized by Crestmark in connection with this sale-leaseback transaction. Such obligation would arise as a result of reductions to the value of the underlying fuel cell project as assessed by the U.S. Internal Revenue Service (&#8220;IRS&#8221;). The Company does not believe that any such obligation is probable based on the facts known as of August 25, 2021. The maximum potential future payments that SBFC could be required to make as a result of this obligation would depend on the difference between the fair value of the fuel cell project sold or financed and the value the IRS would determine as the fair value of the project for purposes of claiming the ITC. The value of the ITC in the sale-leaseback agreements is based on guidelines provided by regulations from the IRS. The Company and Crestmark used a fair value determined with the assistance of an independent third-party appraisal.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The Purchase Agreement and the Lease contain representations and warranties, affirmative and negative covenants, and events of default that entitle Crestmark to cause SBFC&#8217;s indebtedness under the Lease to become immediately due and payable. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Pursuant to a Guaranty Agreement executed on August 25, 2021 by the Company for the benefit of Crestmark (the &#8220;Guaranty&#8221;), the Company has guaranteed the payment and performance of SBFC&#8217;s obligations under the Lease.</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;"><i style="font-style:italic;">East West Bank Tax Equity Financing Transaction</i></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:10pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">The Company closed on a tax equity financing transaction in August 2021 with East West Bancorp, Inc. (&#8220;East West Bank&#8221;) for the 7.4 MW fuel cell project (the &#8220;Groton Project&#8221;) located on the U.S. Navy Submarine Base in Groton, CT, also known as the Submarine Force. East West Bank&#8217;s tax equity commitment totals $15 million (the &#8220;Purchase Price&#8221;).&#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:10pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">This transaction was structured as a "partnership flip," which is a structure commonly used by tax equity investors in the financing of renewable energy projects. Under this partnership flip structure, a partnership, in this case Groton Station Fuel Cell Holdco, LLC (the &#8220;Partnership&#8221;) was organized to acquire from FuelCell Energy Finance II, LLC, a wholly-owned subsidiary of the Company, all outstanding equity interests in Groton Station Fuel Cell, LLC (the &#8220;Project Company&#8221;) which in turn owns the Groton Project and is the party to the power purchase agreement and all project agreements. At the closing of the transaction, the Partnership is owned by East West Bank, holding Class A Units and Fuel Cell Energy Finance Holdco, LLC, a subsidiary of FuelCell Energy Finance, LLC, holding Class B Units. &#160;The acquisition of the Project Company by the Partnership was funded in part by an initial draw from East West Bank and funds contributed downstream to the Partnership by the Company. The initial closing occurred on August 4, 2021, upon the satisfaction of certain conditions precedent (including the receipt of an appraisal and confirmation that the Groton Project would be eligible for the ITC under Section 48 of the Internal Revenue Code of 1986, as amended). &#160;In connection with the initial closing, the Company was able to draw down $3.0 million, of which approximately $0.8 million was used to pay closing costs including appraisal fees, title insurance expenses and legal and consulting fees. The Company is eligible to draw the remaining amount of the commitment, approximately $12 million, once the Groton Project achieves commercial operation. &#160;When such funds are drawn down, the funds will be distributed upstream to the Company, as a reimbursement of prior construction costs incurred by the Company.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:10pt;visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under a partnership flip structure, tax equity investors agree to receive a minimum target rate of return, typically on an after-tax basis. Prior to receiving a contractual rate of return or a date specified in the contractual arrangements, East West Bank will receive substantially all of the non-cash value attributable to the Groton Project, which includes accelerated depreciation and Section 48(a) investment tax credits; however, the Company will receive a majority of the cash distributions (based on the operating income of the Groton Project), which are paid quarterly. After East West Bank receives its contractual rate of return, the Company will receive approximately 95% of the cash and tax allocations. The Company (through a separate wholly owned entity) may enter into a back leverage debt financing transaction and use the cash distributions from the Partnership to service the debt. &#160;</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">Under this partnership flip structure, we have an option to acquire all of the equity interests that East West Bank holds in the Partnership starting approximately five and a half years (the anticipated &#8220;flip&#8221; date) after the Groton Project is operational. If we exercise this option, we are required to pay the greater of the following: (i) the fair market value of East West Bank's equity interest at the time the option is exercised, (ii) 5% of the Purchase Price or (iii) East West Bank&#8217;s claim in liquidation determined using the hypothetical liquidation at book value method. </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. Due to the inherent uncertainty involved in making estimates, actual results in future periods may differ from those estimates.</p><span></span>

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>
