Notes to Consolidated Financial Statements

(Unaudited)

(Tabular amounts in thousands, except share and per share amounts)

Note 1. Nature of Business and Basis of Presentation

FuelCell Energy, Inc. and subsidiaries (the “Company”, “FuelCell Energy”, “we”, “us”, or “our”) is a leading integrated fuel cell company with a growing global presence. We design, manufacture, install, operate and service ultra-clean, efficient and reliable stationary fuel cell power plants. Our Direct FuelCell power plants produce reliable 24/7 base load electricity and usable high quality heat for commercial, industrial, government and utility customers. We have commercialized our stationary carbonate fuel cells and are also pursuing the complementary development of planar solid oxide fuel cell and other fuel cell technologies. We continue to invest in new product and market development and, as such, we are not currently generating positive cash flow from our operations.  Our operations are funded primarily through cash generated from product sales, service and advanced technologies contracts, license fee income and sales of equity and debt securities. In order to produce positive cash flow from operations, we need to be successful at increasing annual order volume, production and cost reduction efforts.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) 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 (“GAAP”) for complete financial statements. In the opinion of management, all normal and recurring adjustments necessary to fairly present our financial position as of April 30, 2013 have been included. All intercompany accounts and transactions have been eliminated.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted.  The balance sheet as of October 31, 2012 has been derived from the audited financial statements at that date, but it does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.These financial statements should be read in conjunction with our financial statements and notes thereto for the year ended October 31, 2012, which are contained in our Annual Report on Form 10-K previously filed with the Securities and Exchange Commission.  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 year.

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation. Service agreement revenue has been separated from Product sales as current year service agreement revenue exceeds the ten percent threshold of Regulation SX Rule 3-05 and revenues and is now combined with license revenue. Beginning in fiscal year 2013, license fees and royalty income have been included within revenues. This change is a result of the new license agreement entered into on October 31, 2012 for our core technology and the harmonization of the agreements to reflect fees and royalties for the manufacture of complete DFC Power Plants. Classification of license fees and royalty income as revenue is reflective of our Asia market partnership and royalty based strategy having become a significant component of non-product revenue. Additionally, Advanced technologies contract revenues has been renamed from Research and development contracts to better describe the sources of revenue from contract research.

The Company has corrected the presentation of restricted cash balances which had been previously included in cash and cash equivalents. As of October 31, 2012, short-term and long-term restricted cash balances in the amount of $5.3 million and $5.3 million, respectively, have been reclassified to short-term and long-term restricted cash. This revision also impacted net cash used in financing activities. There was no impact on net loss or net cash used in operating activities as a result of the revision.

Use of Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the U.S. 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, excess, slow-moving and obsolete inventories, product warranty costs, reserves on service agreements ("SA"), allowance for uncollectible receivables, depreciation and amortization, impairment of assets, taxes, 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.

Concentrations

We contract with a concentrated number of customers for the sale of products, service and advanced technologies contracts. Significant revenues from individual customers for the three and six months ended April 30, 2013 and 2012 included POSCO

Energy (“POSCO”), which is a related party and owns approximately 16 percent of the outstanding common shares of the Company as of April 30, 2013, Dominion Bridgeport Fuel Cell, LLC and the U.S. Government (primarily the Department of Energy).

The percent of consolidated revenues from each customer is presented below.

Note 2. Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

In December 2011, the FASB issued guidance to enhance a financial statement user’s ability to understand the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this guidance includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This guidance also includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. The adoption of this accounting guidance did not have a material impact on our financial position, results of operations or disclosures.

Note 3. Acquisitions

Versa Power Systems, Inc. (“Versa”), our wholly-owned subsidiary working under the Department of Energy's (“DOE”) large-scale hybrid project to develop a coal-based, multi-megawatt solid oxide fuel cell (“SOFC”) based hybrid system. Versa has been developing advanced SOFC systems for various stationary and mobile applications since 2001. We had a 39 percent ownership interest and historically accounted for Versa under the equity method of accounting. We recognized our share of the income or losses as income/(loss) from equity investment on the consolidated statements of operations.

On December 20, 2012, the Company acquired the remaining 61 percent ownership position of Versa in a stock transaction by exchanging approximately 3.5 million shares of its common stock for the outstanding Versa shares held by the other Versa shareholders.

The transaction has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. Step-acquisition accounting guidance was applied and an impairment charge of $3.6 million relating to the previously held equity investment was recorded in the fourth quarter of 2012.

The following table summarizes the allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed as of the acquisition date. This allocation is preliminary and the Company is still in the process of analyzing and evaluating the acquired deferred tax attributes of Versa, if any.  Completion of this review may result in adjustments to the deferred tax attributes and amounts recorded as a result of this acquisition.

Note 10. Share-Based Compensation Plans

We have shareholder approved equity incentive plans and a shareholder approved Section 423 Stock Purchase Plan (the “ESPP”). We account for stock awards to employees and non-employee directors under the fair value method. We determine the fair value of stock options at the grant date using the Black-Scholes valuation model. The model requires us to make estimates and assumptions regarding the expected life of the award, the risk-free interest rate, the expected volatility of our common stock price and the expected dividend yield. The fair value of restricted stock units ("RSU") and restricted stock awards (“RSA”) is based on the common stock price on the date of grant. The fair value of stock awards is amortized to expense over the vesting period, generally four years.

Share-based compensation reflected in the consolidated statements of operations were as follows:

	Three Months Ended April 30,				Six Months Ended April 30,
	2013		2012		2013		2012
Costs of revenues	$	149	$	93	$	281	$	253

OVERVIEW AND RECENT DEVELOPMENTS

Overview

We are a leading integrated fuel cell company with a growing global presence. We design, manufacture, install, operate and service ultra-clean, efficient and reliable stationary fuel cell power plants. Our power plants offer scalable on-site power and utility grid support, helping customers solve their energy, environmental and business challenges.

Global urban populations are expanding, becoming more industrialized and requiring greater amounts of power to sustain their growth. As policymakers and power producers struggle to find economical and readily available solutions that will alleviate the impact of harmful pollutants and emissions, the market for ultra-clean, efficient and reliable distributed generation is rapidly growing.

With fully commercialized ultra-clean fuel cell power plants and decades of experience in the industry, we are well positioned to grow our installed base of power plants. Our plants are operating in more than 50 locations worldwide and have generated more than 1.6 billion kilowatt hours (kWh) of electricity, which is equivalent to powering more than 145,000 average size U.S. homes for one year. Our installed base and steadily growing backlog exceeds 300 megawatts (MW).

Our diverse and growing customer base includes major utility companies, municipalities, universities, government entities and businesses in a variety of commercial and industrial enterprises. Our leading geographic markets are South Korea and the United States and we are actively pursuing expanding opportunities in Asia, Europe and Canada.

15

We service the power plants for virtually every customer we have globally under long term service agreements. We monitor and operate the power plants around the clock from our technical assistance center located at our Danbury, Connecticut headquarters. We have an extensive service network of FuelCell Energy technicians who provide on-site service and maintenance.

Recent Developments

Operations update

The annual production run-rate at the Torrington, Connecticut production facility was increased to 70 MW as of May 1, 2013 to meet backlog. The change in production levels represented an increase of 25 percent from the production levels of 56 MW annually maintained during the second quarter of 2013.

The Company's supply chain has ramped to keep up with production levels. The Company has also hired direct labor for the Torrington manufacturing facility to support increasing production volumes. Resources are being added to support demand.

Engineering and assembly of fuel cell power plants commenced at the FuelCell Energy Solutions ("FCES") manufacturing facility in Germany during the second quarter of 2013.

Installations Update

Construction of the 14.9 MW fuel cell park in Bridgeport, Connecticut is on schedule to deliver full power by the end of calendar year 2013. The first two fuel cell modules have been delivered to the site with subsequent deliveries scheduled during the summer and early fall. The inter-connection work to connect the fuel cell park to the electric grid via three substations is more than 90 percent complete.

The construction performed by POSCO Energy of the 59 MW fuel cell park in Hwasung City, South Korea continues to progress with twelve of the 2.8 MW DFC3000^® power plants on site and the remaining nine plants to be delivered during the summer and early fall. Commissioning has begun for the initial power plant installations. The fuel cell park will be brought to full power by the end of 2013 or early 2014.

In Europe, the fuel cell power plant purchased by The Crown Estate and installed inside the Regent Street mixed-use office/residential/retail complex in central London, England is undergoing commissioning. Construction of both the 20 Fenchurch office tower in London and the Federal Ministry of Education and Research government complex in Berlin, Germany is progressing. The fuel cell power plant for the Berlin installation is being assembled at the FCES manufacturing facility.

Market Update

A 1.4 MW DFC1500^® power plant was sold during the second quarter of 2013 for installation at a hospital in Hartford, Connecticut. The power plant will be configured for combined heat and power with the heat being supplied to both the hospital and a nearby school. The project is part of the State of Connecticut Low-emission Renewable Energy Credit (LREC) program.

The Company has approximately 18 megawatts of approved projects under the Connecticut Project 150 program. Legislation was recently approved that extended the required start-date of these projects by 24 months. The required start dates now range from May 2015 to September 2015. The Company is seeking project investors to purchase and own the power plants. Similar to the Bridgeport fuel cell park, the Company is developing the projects, will provide the fuel cell power plants, and expects to provide installation/engineering, procurement and construction services, and then operate and maintain the plants over the term of the power purchase agreement.

These are discussed throughout the ‘Results of Operations’ and ‘Liquidity and Capital Resources’ sections.

Comparison of Three Months Ended April 30, 2013 and 2012

Revenues and Costs of revenues

Our revenues and cost of revenues for the three months ended April 30, 2013 and 2012 were as follows:

	Three Months Ended April 30,						Change
	2013			2012			$		%
Total revenues	$	42,436		$	24,153		$	18,283	76

Product sales and service and license revenues

Our product sales and service and license revenues and cost of revenues for the three months ended April 30, 2013 and 2012 were as follows:

	Three Months Ended April 30,					Change
	2013		2012			$			%
Revenues:
Product sales	$	34,375	$	18,657		$	15,718		84
Service agreements and license revenues		4,108		3,454			654		19

Gross profit (loss) from service agreements and license revenues		204		(488	)		692		142
Total	$	2,096	$	30		$	2,066		6,887
Product sales costs-to-revenues ratio (1)	0.94		0.97
Service agreement revenues costs-to-revenues ratio (1)	0.95		1.14

(1) Cost-to-revenue ratio is calculated as cost of revenues divided by revenues.

Product sales and service agreements and license revenues increased $16.4 million, or 74 percent, in the three months ended April 30, 2013 to $38.5 million compared to $22.1 million for the prior year period. The increase reflects higher fuel cell kit sales combined with revenue of approximately $8.9 million from the Bridgeport fuel cell park project. Beginning in the first quarter of 2013, license revenue is being recorded as service agreements and license revenues. This change in prospective classification is due to the new license agreement entered into on October 31, 2012 for our core technology and the harmonization of POSCO licensing and royalty agreements to reflect fees and royalties for the exclusive rights to sell, install, service and repair complete DFC Power Plants in the Asia Market. License revenue in the second quarter of 2013 was approximately $1.0M. Cost of product sales and service and license revenues increased $14.3 million, or 65 percent for the three months ended April 30, 2013 to $36.4 million compared to $22.1 million in the prior year period. Margins in the second quarter of 2013 were favorably impacted by revenue recognition from the construction of complete power plants.

Gross profit for product sales and service agreements and license revenues for the three months ended April 30, 2013 is $2.1 million, compared to gross profit of $0.03 million for the three months ended April 30, 2012. The cost-to-revenue ratio for product sales was 0.94-to-1.00 for the three months ended April 30, 2013 compared to 0.97-to-1.00 for the three months ended April 30, 2012.

Cost of product sales includes costs to design, engineer, manufacture and ship our power plants and power plant components to customers, site engineering and construction costs where we are responsible for power plant system installation, costs for stack module assembly and conditioning equipment sold to POSCO, warranty expense, liquidated damages and inventory excess and obsolescence charges. Cost of service agreements and license revenues include maintenance and stack replacement costs to service power plants for customers with service agreements and operating costs for our units under power purchase agreements (“PPA”).

Product Sales and Cost of Sales

Product sales for the three months ended April 30, 2013 included $29.3 million from the sale of power plants and fuel cell kits and $5.1 million of revenue primarily related to power plant component sales and site engineering and construction services relating to the Bridgeport fuel cell park project. This compared to product sales for the three months of April 30,

18

2012 which included $14.3 million from the sale of power plants and fuel cell kits and $4.4 million of revenue primarily from power plant component sales and site engineering and construction services.

Cost of product sales increased $14.3 million for the three months ended April 30, 2013 to $32.5 million, compared to $18.1 million in the same period the prior year. Gross profit increased $1.4 million to a gross profit of $1.9 million for the three months ended April 30, 2013 compared to a gross profit of $0.5 million for the three months ended April 30, 2012 due to a sales mix that included complete power plants and installation services along with fuel cell kits.

The annual production run-rate at the Torrington, Connecticut production facility was increased to 70MW as of May 1, 2013 to meet backlog. More than 50 direct manufacturing positions have been added since the start of the first quarter to support the production ramp. The Company's headcount globally, including temporary workers, totaled 636 employees. Higher production volumes support increased quarterly revenue in 2013 and is expected to lead to expanding margins from improved absorption of fixed overhead costs and broadening of the revenue mix to include complete power plant sales in North America and Europe.

Service and License Revenues and Cost of Revenues

Revenues for the three months ended April 30, 2013 from service and power purchase agreements and license fee and royalty agreements totaled $4.1 million, compared to $3.5 million for the same period in the prior year. The increase relates to the inclusion of license and royalty income within revenues beginning in the first quarter of fiscal year 2013. The change in classification is a result of the new license and royalty agreement entered into with POSCO on October 31, 2012 for our core technology and the harmonization of the existing agreements to reflect fees and royalties to be earned for the rights to sell, install, service and repair complete DFC Power Plants. Classification of license and royalty income as revenue is reflective of our Asia market partnership and royalty based strategy and this business activity becoming an ongoing significant component of our central operations. Service and license cost of revenues remained at $3.9 million for both periods. The gross profit on service and license agreements increased to $0.2 million for the three months ended April 30, 2013, compared to a gross loss of $0.5 million for the prior year period. The historical loss on service agreements has been due to high maintenance, stack replacement and other costs on older and sub-MW product designs. As more profitable megawatt-class service agreements are executed and as early generation sub-megawatt products are retired or become a smaller overall percentage of the installed fleet, we expect the margins on service agreements to increase.

Advanced technologies contracts

Advanced technologies contracts revenue and related costs for the three months ended April 30, 2013 and 2012 were as follows:

	Three Months Ended April 30,				Change
	2013		2012		$		%
Advanced technologies contracts	$	3,953	$	2,042	$	1,911	94
Cost of advanced technologies contracts		3,735		1,871	1,864		100
Gross profit	$	218	$	171	$	47	27

Advanced technologies contracts revenue for the three months ended April 30, 2013 was $4.0 million, which increased $1.9 million when compared to $2.0 million of revenue for the three months ended April 30, 2012. Cost of advanced technologies contracts increased $1.9 million to $3.7 million for the three months ended April 30, 2013, compared to $1.9 million for the same period in the prior year. Gross profit from advanced technology contracts for the three months ended April 30, 2013 was $0.2 million or 6 percent, compared to $0.2 million or 8 percent for the three months ended April 30, 2012. The decrease in margins is due to the mix of cost share on contracts with activity during the period.

We contract with a concentrated number of customers for the sale of our products and for advanced technology contracts. Refer to Note 1 of notes to consolidated financial statements for more information on customer concentrations.

There can be no assurance that we will continue to achieve historical levels of sales of our products to our largest customers. Even though our customer base is expected to increase and our revenue streams to diversify, a substantial portion of net revenues could continue to depend on sales to a concentrated number of customers. Our agreements with these customers may be canceled if we fail to meet certain product specifications or materially breach the agreements, and our customers may seek to renegotiate the

19

terms of current agreements or renewals. The loss of, or reduction in sales to, one or more of our larger customers, could have a material adverse effect on our business, financial condition and results of operations.

Administrative and selling expenses

Administrative and selling expenses were $5.4 million for the three months ended April 30, 2013 compared to $4.0 million during the three months ended April 30, 2012. Administrative and selling expenses increased as a result of increased business development activity in the European market and administrative costs arising from the consolidation of Versa into the Company's results.

Research and development expenses

Research and development expenses remained relatively consistent at $4.1 million during the three months ended April 30, 2013 when compared to $4.0 million for the same period in 2012. Our internal research and development focus continues to be on initiatives that have near term product implementation potential and product cost reduction opportunities.

Loss from operations

Loss from operations for the three months ended April 30, 2013 was $7.2 million compared to a loss of $7.8 million for the same period in 2012. The decrease was a result of favorable gross profit from product sales and service agreements and license revenue offset by higher business development activity and administrative costs.

Interest expense

Interest expense for the three months ended April 30, 2013 and 2012 was $0.6 million. Interest expense for both periods includes interest for the amortization of the redeemable preferred stock of subsidiary of $0.5 million and $0.6 million, respectively.

Loss from equity investments

A loss of $0.2 million was recorded for our share of Versa's losses for this investment for the three months ended April 30, 2012.

License fee and royalty income

License fee and royalty income for the three month period ended April 30, 2012 was $0.4 million which represents amounts earned from POSCO. Beginning in fiscal year 2013, license fees and royalty income have been included within revenues under service and license revenues. Refer to Critical Accounting Policies and Estimates for further discussion on this change.

Other income (expense), net

Other income (expense), net, was income of $0.2 million for the three month period ended April 30, 2013 compared to an expense of $0.4 million for the same period in 2012.

Provision for income taxes

We have not paid federal or state income taxes in several years due to our history of net operating losses, although we have paid foreign taxes in South Korea. For the three months ended April 30, 2013 our provision for income taxes was insignificant. We have begun manufacturing products that are gross margin profitable on a per unit basis; however, we cannot estimate when production volumes will be sufficient to generate taxable domestic income. Accordingly, no tax benefit has been recognized for these net operating losses or other deferred tax assets as significant uncertainty exists surrounding their recoverability.

Net loss attributable to noncontrolling interest

The net loss attributed to the noncontrolling interest for the three months ended April 30, 2013 and 2012 was $0.3 million and $0.1 million, respectively.

Preferred Stock dividends

Dividends recorded on the Series B Preferred Stock were $0.8 million in each of the three month periods of April 30, 2013, and 2012.

20

Net loss to common shareholders and loss per common share

Net loss to common shareholders represents the net loss for the period less the net loss attributable to noncontrolling interest, less the preferred stock dividends on the Series B Preferred Stock. For the three month periods ended April 30, 2013 and 2012, net loss to common shareholders was $8.2 million and $9.1 million, respectively and loss per common share was $(0.04) and $(0.06), respectively.

Comparison of Six Months Ended April 30, 2013 and 2012

Revenues and Costs of revenues

Product sales and service and license revenues

Our product sales and service and license revenues and cost of revenues for the six months ended April 30, 2013 and 2012 were as follows:

	Six Months Ended April 30,						Change
	2013			2012			$			%
Revenues:
Product sales	$	63,440		$	44,859		$	18,581		41

Service agreement revenues costs-to-revenues ratio (1)	1.14			1.20

(1) Cost-to-revenue ratio is calculated as cost of revenues divided by revenues.

Product sales and service agreements and license revenues increased $20.8 million, or 40 percent, in the six months ended April 30, 2013 to $72.5 million compared to $51.7 million for the prior year period. The increase is due to higher fuel cell kit sales, revenue recognition for the Bridgeport fuel cell park project of approximately $14.7 million and license and royalty income. Cost of product sales and service and license revenues increased $23.1 million, or 46 percent for the six months ended April 30, 2013 to $72.8 million compared to $49.7 million in the same period in the prior year. The Company incurred warranty and after-market costs during fiscal year 2013 as a result of a select number of fuel cell stacks requiring repair. This issue has been thoroughly investigated, process changes implemented, and field repairs undertaken to support the limited number of customers impacted.

Gross loss for product sales and service agreements and license revenues is $0.3 million, compared to gross profit of $2.0 million for the six months ended April 30, 2012. The cost-to-revenue ratio for product sales was .98 -to-1.00 for the six months ended April 30, 2013 compared to 0.93-to-1.00 for the six months ended April 30, 2012.

Product Sales and Cost of Sales

Product sales for the six months ended April 30, 2013 included $54.3 million from the sale of power plants and fuel cell kits and $9.1 million of revenue primarily related to power plant component sales and site engineering and construction services relating to the Bridgeport fuel cell park project. This compared to product sales for the six months ended April 30, 2012 which included $35.2 million from the sale of power plants and fuel cell kits and $9.7 million of revenue primarily from power plant component sales and site engineering and construction services.

Cost of product sales increased $20.9 million for the six months ended April 30, 2013 to $62.4 million, compared to $41.5 million in the same period the prior year. Gross profit decreased $2.3 million to a gross profit of $1.0 million in the six months ended April 30, 2013 compared to a gross profit of $3.4 million for the six months ended April 30, 2012 due to a select number of fuel cell stacks requiring repair and costs related to the Company's undertaking to increase production.

22

The annual production run-rate was increased to 70 MW as of May 1, 2013 to meet backlog. Higher production volumes support increased quarterly revenue in 2013 and will lead to expanding margins from improved absorption of fixed overhead costs and broadening of the revenue mix to include complete power plant sales in North America and Europe.

Service and License Revenues and Cost of Revenues

Revenues for the six months ended April 30, 2013 from service agreements and license fee and royalty agreements totaled $9.1 million, compared to $6.9 million for the same period in the prior year. The increase primarily relates to the inclusion of license and royalty income within revenues beginning in the first quarter of fiscal year 2013. Service agreements and license cost of revenues increased to $10.4 million from $8.2 million for the prior year period. The gross loss on service agreements and license agreements remained consistent at $1.3 million for the six months ended April 30, 2013, compared to $1.4 million for the comparable prior year period. The slight decrease in service and license agreement margins is primarily due to additional costs incurred on service agreements in the 2013 period including the assembly quality issue discussed above under Product Sales and Cost of Sales . The historical loss on service agreements has been due to high maintenance, stack replacement and other costs on older and sub-MW product designs. As profitable megawatt-class service agreements are executed and as early generation sub-megawatt products are retired or become a smaller overall percentage of the installed fleet, we expect the margins on service agreements to increase.

Advanced technologies contracts

Advanced technologies contracts revenue and related costs for the six months ended April 30, 2013 and 2012 were as follows:

	Six Months Ended April 30,				Change
	2013		2012		$			%
Advanced technologies contracts	$	6,277	$	3,779	$	2,498		66
Cost of advanced technologies contracts		5,975		3,444	2,531			73
Gross profit	$	302	$	335	$	(33	)	(10	)

Advanced technologies contracts revenue for the six months ended April 30, 2013 was $6.3 million, which increased $2.5 million when compared to $3.8 million of revenue for the six months ended April 30, 2012. Cost of advanced technologies contracts increased $2.5 million to $6.0 million for the six months ended April 30, 2013, compared to $3.4 million for the same period in the prior year. Gross profit from advanced technologies contracts for the six months ended April 30, 2013 was $0.3 million or 5 percent, compared to $0.3 million or 9 percent for the six months ended April 30, 2012. The decrease in margins is due to the mix of cost share on contracts with activity during the period.

Administrative and selling expenses

Administrative and selling expenses were $10.9 million for the six months ended April 30, 2013 compared to $7.8 million during the six months ended April 30, 2012. Administrative and selling expenses increased primarily as a result of increased business development activity in the U.S. and Europe and consolidation of Versa's results with the Company in fiscal 2013.

Research and development expenses

Research and development expenses decreased $0.3 million to $7.4 million during the six months ended April 30, 2013, compared to $7.7 million for the same period in 2012. The decrease reflects a shift in resources to focus on the previously discussed manufacturing quality issue on a select batch of fuel cell stacks. Our internal research and development focus continues to be on initiatives that have near term product implementation potential and product cost reduction opportunities.

Loss from operations

Loss from operations for the six months ended April 30, 2013 was $18.3 million compared to a loss of $13.2 million for the same period in 2012. The increase was a result of a quality issue identified in a select batch of fuel cell stacks and increased business development activity which increased administrative and selling expenses.

23

Interest expense

Interest expense for the six months ended April 30, 2013 and 2012 was $1.1 million and $1.2 million, resectively. Interest expense for both periods includes interest for the amortization of the redeemable preferred stock of subsidiary of $1.0 million and $1.2 million, respectively.

Income/(loss) from equity investments

Equity in income of $.04 million recorded in the six months ended April 30, 2013 represents our share of Versa's income through the acquisition date. A loss of $0.5 million was recorded for our share of Versa's losses for this investment for the six months ended April 30, 2012.

License fee and royalty income

License fee income for the six month period ended April 30, 2012 was $0.8 million which represents the license fee and royalty income earned from POSCO. Beginning in fiscal year 2013, license fees and royalty income have been included within revenues under service agreements and license revenues. Refer to Critical Accounting Policies and Estimates for further discussion on this change.

Other income (expense), net

Other income (expense), net, was an expense of $0.1 million for the six month period ended April 30, 2013 compared to an expense of $0.2 million for the same period in 2012.

Provision for income taxes

We have not paid federal or state income taxes in several years due to our history of net operating losses, although we have paid foreign taxes in South Korea. For the six months ended April 30, 2013 our provision for income taxes was insignificant. We have begun manufacturing products that are gross margin profitable on a per unit basis; however, we cannot estimate when production volumes will be sufficient to generate taxable domestic income. Accordingly, no tax benefit has been recognized for these net operating losses or other deferred tax assets as significant uncertainty exists surrounding the recoverability of these deferred tax assets.

Net loss attributable to noncontrolling interest

The net loss attributed to the noncontrolling interest for the six months ended April 30, 2013 and October 31, 2012 was $0.5 million and $0.1 million, respectively.

Preferred Stock dividends

Dividends recorded on the Series B Preferred Stock were $1.6 million in each of the six month periods of April 30, 2013 and 2012.

Net loss to common shareholders and loss per common share

Net loss to common shareholders represents the net loss for the period, less the net loss attributable to noncontrolling interest and less the preferred stock dividends on the Series B Preferred Stock. For the six month periods ended April 30, 2013 and 2012, net loss to common shareholders was $20.6 million and $15.8 million, respectively and loss per common share was $(0.11).

LIQUIDITY AND CAPITAL RESOURCES

The Company's future liquidity will be dependent on obtaining the order volumes and cost reductions necessary to achieve profitable operations. The Company expects to generate gross profit from product sales and revenues with production volumes in the range of 50 MW to 55 MW on an annualized basis. Increasing annual order volume and reduced product costs are expected to reduce annual cash use and we expect positive cash flows and net income profitability at an annual production rate of 80 - 90 MW. Actual results will depend on product mix, volume, future service costs and market pricing.

The production capacity at our manufacturing facility is 90 MW with full utilization under its current configuration. Numerous actions were undertaken during the first half of fiscal year 2013 to increase the annual production run-rate at the Torrington, Connecticut facility to 70 MW as a result of increased backlog.

24

The 121.8 MW POSCO order, combined with scheduled re-stacks of existing power plant installations that are currently under service agreements is expected to provide a base level of production of approximately 50 MW per year through 2016 at the Company's production facility in Torrington, Connecticut. As order flow dictates, the Company will ramp up production to meet demand. EBITDA (earnings before interest, taxes, depreciation and amortization) breakeven is expected with annual production volume of approximately 80 MW.

The cell license agreement has multiple benefits for both FuelCell Energy and POSCO. POSCO is currently designing and will construct a cell manufacturing facility in South Korea capacity capable of producing up to 140 MW of product annually. Production in South Korea will improve responsiveness for meeting demand under the Renewable Portfolio Standard. The Company will avoid capital investment for Asian market development and will benefit from market expansion by receiving a royalty payment from POSCO for each power plant sold, with a 15 year royalty term. Establishing a second source of supply for fuel cell modules mitigates a risk factor for prospective customers evaluating long term fuel cell power plant projects that include scheduled replacement stacks. Increased production volume, whether in the USA or South Korea, will reduce the cost of DFC plants, further spurring market adoption.

If demand develops beyond the combined capacity of the Company and POSCO, we have the ability to further expand production capacity at our Torrington facility to approximately 150 MW. This expansion would require the addition of equipment (e.g. furnaces, tape casting and other equipment) to increase the capacity of certain manufacturing operations. Due to the economies of scale and equipment required, we believe it is more cost effective to add capacity in large blocks. We estimate that an expansion of the Company's Torrington facility to 150 MW would require additional capital investments of $30 to $40 million, although this expansion may occur in stages depending on the level of market demand.

In addition to cash flows from operations, we may also pursue raising capital through a combination of; (i) equity or strategic investments, (ii) debt financing (with improving operating results as the business grows, the Company expects to have access to the debt markets to finance capital expansion) and (iii) potential local or state Government loans or grants in return for manufacturing job creation. The timing and size of any financing will depend on multiple factors including market conditions, future order flow and the need to adjust production capacity. If we are unable to raise additional capital, our growth potential may be adversely affected and we may have to modify our plans. We anticipate that our existing capital resources, together with anticipated order, revenues and cash flows, will be adequate to satisfy our financial requirements and agreements through at least the next twelve months.

Cash Flows

Cash and cash equivalents and restricted cash and cash equivalents totaled $71.7 million as of April 30, 2013 compared to $57.5 million as of October 31, 2012. As of April 30, 2013, Restricted cash and cash equivalents was $15.6 million, of which $10.7 million was classified as current and $5.0 million was classified as long-term compared to $10.6 million total restricted cash and cash equivalents as of October 31, 2012, of which $5.3 million was classified as current and $5.3 million was classified as long-term. The key components of our cash inflows and outflows were as follows:

Operating Activities – Net cash provided by operating activities was $16.1 million during the first six months of 2013 compared to $30.1 million net cash used in operating activities during the first six months of 2012. Net cash provided by operating activities for the first six month period of 2013 is a result of an increase in deferred revenues of $19.7 million relating to customer milestone billings, a decrease in accounts receivable of $7.7 million from customer collections and an increase in accounts payable of $6.8 million resulting from the increased production rate. These were partially offset by a decrease in accrued liabilities of $2.4 million. Net cash used of $30.1 million during the first six months of 2012 related to a decrease in deferred revenues of $10.2 million due to lower progress payments on commercial orders, an increase of $12.6 million in inventory relating to the build of inventory for future orders and a decrease in accrued liabilities of $2.7 million partially offset by an increase in accounts receivable.

Investing Activities – Net cash used in investing activities was $2.2 million during the first six months of 2013 compared to net cash provided by investing activities of $10.3 million during the first six months of 2012. The net cash used in investing activities for the first six months of 2013 related to capital expenditures of $2.6 million, partially offset by cash acquired from the Versa acquisition of $0.4 million. Cash provided by investing activities during the first six months of 2012 relates to the maturity of U.S. treasuries of $12.0 million, partially offset by capital expenditures of $1.7 million.

Financing Activities – Net cash used in financing activities was $4.8 million during the first six months of 2013 compared to net cash provided by financing activities of $23.7 million in the prior year period. The net cash used in financing activities during the first six months of 2013 was related to an increase in restricted cash of $5.0 million to for of credit issued to support the Company's obligations under customer contracts and also the payment of preferred dividends and return of capital of $2.2 million offset by proceeds from the CEFIA Loan of $2.6 million. The first six months of 2012 included proceeds from the routine sale of common stock of $2.0 million and net proceeds from the public offering of 23.0 million shares of common stock for proceeds of $32.0 million and an increase in restricted cash of $2.9 million for letters of credit

25

issued to support the Company's obligations under customer contracts offset by the payment of preferred dividends and return of capital of $5.3 million.

Sources and Uses of Cash and Investments

We continue to invest in new product and market development and, as such, we are not currently generating positive cash flow from our operations on a consistent basis. Our operations are funded primarily through cash generated from product sales and advanced technology contracts, license fee income and raising capital. In order to consistently produce positive cash flow from operations, we need to be successful at increasing annual order volume and implementing our cost reduction efforts. Please see our Form 10-K for the fiscal year ended October 31, 2012 for further details.

Commitments and Significant Contractual Obligations

A summary of our significant future commitments and contractual obligations as of April 30, 2013 and the related payments by fiscal year are as follows:

	Payments Due by Period
	Total		Less than 1 Year		1 – 3 Years		3 – 5 Years		More than 5 Years
Purchase commitments (1)	$	94,011	$	81,855	$	12,118	$	38	$	—

Capital and operating lease commitments (3)	5,128		2,087		2,279		571		191
Revolving Credit Facility (4)	4,000		4,000		—		—		—
Series B Preferred dividends payable (5)
Totals	$	123,640	$	89,394	$	17,293	$	3,551	$	13,402

(1) Purchase commitments with suppliers for materials, supplies and services incurred in the normal course of business.

(2) On March 31, 2011, the Company entered into an agreement with Enbridge, Inc. (“Enbridge”) to modify the Class A Cumulative Redeemable Exchangeable Preferred Share Agreement (the “Series 1 Preferred Share Agreement”). The terms of the Series 1 preferred share agreement require payments of (i) an annual amount of Cdn$500,000 for dividends and (ii) an amount of Cdn.$750,000 as return of capital payments payable in cash. These payments commenced on March 31, 2011 and will end on December 31, 2020. Dividends accrue at a 1.25% quarterly rate on the unpaid principal balance, and additional dividends will accrue on the cumulative unpaid dividends (inclusive of the Cdn.$12.5 million unpaid dividend balance as of the modification date) at a rate of 1.25% per quarter, compounded quarterly. On December 31, 2020 the amount of all accrued and unpaid dividends on the Class A Preferred Shares of Cdn$21.1 million and the balance of the principal redemption price of Cdn.$4.4 million will be due to the holders of the Series 1 preferred shares. The Company has the option of making dividend payments in the form of common stock or cash under terms outlined in the preferred share agreement. For purposes of preparing the above table, the final balance of accrued and unpaid dividends due December 31, 2020 of Cdn.$21.1 million is assumed to be paid in the form of common stock and not included in this table.

(3) Future minimum lease payments on capital and operating leases.

(4) The amount represents the amount outstanding as of April 30, 2013 on a $8.0 million revolving credit facility with JPMorgan Chase Bank, N.A. and the Export-Import Bank of the United States. The credit facility is used for working capital to finance the manufacture and production and subsequent export sale of the Company’s products or services. The agreement has a one year term with renewal provisions and the current expiration date is April 2, 2014.  The outstanding principal balance of the facility will bear interest, at the option of the Company of either the one-month LIBOR plus 1.5 percent or the prime rate of JP Morgan Chase. The facility is secured by certain working capital assets and general intangibles, up to the amount of the outstanding facility balance.

(5) We pay $3.2 million in annual dividends on our Series B Preferred Stock. The $3.2 million annual dividend payment has not been included in this table as we cannot reasonably determine the period when or if we will be able to convert the Series B Preferred Stock into shares of our common stock. We may, at our option, convert these shares into the number of shares of our common stock that are issuable at the then prevailing conversion rate if the closing price of our common stock exceeds 150 percent of the then prevailing conversion price ($11.75) for 20 trading days during any consecutive 30 trading day period.

In April 2008, we entered into a 10-year loan agreement with the Connecticut Development Authority allowing for a maximum amount borrowed of $4.0 million. At April 30, 2013, we had an outstanding balance of $3.4 million on this loan. The interest

26

rate is 5 percent and the loan is collateralized by the assets procured under this loan as well as $4.0 million of additional machinery and equipment. Repayment terms require interest and principal payments through May 2018.

On March 5, 2013 the Company closed on a new long-term loan agreement with the Connecticut Clean Energy and Finance Investment Authority (CEFIA) totaling $5.9 million in support of the Bridgeport project. The loan agreement to carries an interest rate of 5.0% and principal repayments will commence on the eighth anniversary of the project's provisional acceptance date, which has yet to be determined, in forty eight equal monthly installments. An advance of $2.6 million was made under the CEFIA Note during the second quarter of 2013. A prior loan from the Connecticut Clean Energy Fund Note in the amount outstanding of $0.9 million was rolled into the new CEFIA Note. The outstanding balance on the CEFIA Note as of April 30, 2013 was $3.5 million.

We have pledged approximately $15.6 million of our cash and cash equivalents as collateral and letters of credit for certain banking requirements and contracts. As of April 30, 2013, outstanding letters of credit totaled $13.1 million. These expire on various dates through April 2019.

As of October 31, 2012, we have uncertain tax positions aggregating $15.7 million and have reduced our net operating loss carryforwards by this amount. Because of the level of net operating losses and valuation allowances, unrecognized tax benefits, even if not resolved in our favor, would not result in any cash payment or obligation and therefore have not been included in the contractual obligation table above.

In addition to the commitments listed in the table above, we have the following outstanding obligations:

Power purchase agreements

In California, we have 1.5 MW of power plant installations under power purchase agreements ranging in duration from five to seven years. As owner of the power plants, we are responsible for all operating costs necessary to maintain, monitor and repair the power plants. Under certain agreements, we are also responsible for procuring fuel to run the power plants.

Service and warranty agreements

We warranty our products for a specific period of time against manufacturing or performance defects. Our standard warranty period is generally 15 months after shipment or 12 months after acceptance of the product. We have agreed to warranty kits and components for 21 months from the date of shipment due to the additional shipping and customer manufacture time required. In addition to the standard product warranty, we have contracted with certain customers to provide services to ensure the power plants meet minimum operating levels for terms ranging from one to 20 years. Our standard and most prevalent services agreement term is five years. Pricing for service contracts is based upon estimates of future costs, which could be materially different from actual expenses. Also see Critical Accounting Policies and Estimates for additional details.

Research and development cost-share contracts (Advanced technologies contracts)

Advanced technologies contract revenues has been renamed from Research and development contracts to better describe the sources of revenue from contract research. We have contracted with various government agencies to conduct research and development as either a prime contractor or sub-contractor under multi-year, cost-reimbursement and/or cost-share type contracts or cooperative agreements. Cost-share terms require that participating contractors share the total cost of the project based on an agreed upon ratio. In many cases, we are reimbursed only a portion of the costs incurred or to be incurred on the contract. While government research and development contracts may extend for many years, funding is often provided incrementally on a year-by-year basis if contract terms are met and Congress authorizes the funds. As of April 30, 2013, Advanced technologies contracts backlog totaled $14.1 million, of which $6.6 million is funded. Should funding be delayed or if business initiatives change, we may choose to devote resources to other activities, including internally funded research and development.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

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. Actual results could differ from those estimates. Estimates are used in accounting for, among other things, revenue recognition, contract loss reserves, excess, slow-moving and obsolete inventories, product warranty costs, reserves on SA's, share-based compensation expense, allowance for doubtful accounts, depreciation and amortization, impairment of long-lived assets, purchase accounting, income taxes 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.

27

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. Our accounting policies are set-forth below.

Revenue Recognition

We earn revenue from (i) the sale and installation of fuel cell power plants and modules (ii) the sale of component part kits and spare parts to customers, (iii) site engineering and construction services (iv) providing services under SA's, (v) the sale of electricity under PPA's as well as incentive revenue from the sale of electricity under PPA's, (vi) license fees and royalty income from manufacturing and technology transfer agreements, and (vii) customer-sponsored advanced technology projects. The Company periodically enters into arrangements with customers that involve multiple elements of the above items. We assess such contracts to evaluate whether there are multiple deliverables, and whether the consideration under the arrangement is being appropriately allocated to each of the deliverables. Our revenue is primarily generated from customers located throughout the U.S. and Asia and from agencies of the U.S. Government. Revenue from product and kit sales, construction services and component part kits revenue is recorded as product sales in the consolidated statements of operations. Revenue from SA's, PPA's, license and royalty revenue and engineering services revenue is recorded as service and license revenues and revenue from customer-sponsored advanced technology from research and development projects is recorded as advanced technologies contract revenues in the consolidated statements of operations.

For customer contracts for complete DFC Power Plants which the Company has adequate cost history and estimating experience and that management believes it can reasonably estimate total contract costs, revenue is recognized under the percentage of completion method of accounting. The use of percentage of completion accounting requires significant judgment relative to estimating total contract costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, anticipated increases in wages and prices for subcontractor services and materials, and the availability of subcontractor services and materials. Our estimates are based upon the professional knowledge and experience of our engineers, program managers and other personnel, who review each long-term contract on a quarterly basis to assess the contract's schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods. Revenues are recognized based on the percentage of the contract value that incurred costs to date bear to estimated total contract costs, after giving effect to estimates of costs to complete based on most recent information. For customer contracts for new or significantly customized products, where management does not believe it has the ability to reasonably estimate total contract costs, revenue is recognized using the completed contract method and therefore all revenue and costs for the contract are deferred and not recognized until installation and acceptance of the power plant is complete. For all types of contracts, we recognize anticipated contract losses as soon as they become known and estimable. We have recorded an estimated contract loss reserve of $0.04 million as of April 30, 2013 and October 31, 2012. Actual results could vary from initial estimates and reserve estimates will be updated as conditions change.

Revenue from component part kits and spare parts sales is recognized upon shipment or title transfer under the terms of the customer contract. Terms for certain contracts provide for a transfer of title and risk of loss to our customers at our factory locations upon completion of our contractual requirement to produce products and prepare the products for shipment. A shipment in place may occur in the event that the customer is unready to take delivery of the products on the contractually specified delivery dates.

Site engineering and construction services revenue is recognized on a percentage of completion basis as costs are incurred.

Revenue from service agreement contracts is generally recorded ratably over the term of the SA, as our performance of routine monitoring and maintenance under these SA's are generally expected to be incurred on a straight-line basis. For SA's where we expect to have a restack at some point during the term (generally SA's in excess of five years), the costs of performance are not expected to be incurred on a straight-line basis, and therefore, a portion of the initial value related to the stack replacement is deferred and is recognized upon such stack replacement event. In the event a restack occurs whereby the stack estimated useful life exceeds the remaining contract term and if the customer agrees at the time of a restack to return the stack to the Company at the end of the term, the cost of the stack is recorded as a long-term asset and depreciated over its expected life, in which case we would record the remaining SA revenue ratably over the remaining term. If the Company does not obtain rights to title from the customer upon a restack, the cost of the stack is expensed.

Under PPA's, revenue from the sale of electricity is recognized as electricity is provided to the customer. Incentive revenue is recognized ratably over the term of the PPA.

The Company receives license fees and royalty income from POSCO as a result of manufacturing and technology transfer agreements entered into in 2007, 2009 and 2012. On October 31, 2012, we entered into a new license agreement; Cell Technology Transfer Agreement which provides POSCO with the technology to manufacture Direct FuelCell power plants in South Korea and the market access to sell power plants throughout Asia. In conjunction with this agreement we amended the 2010-year manufacturing and distribution agreement with POSCO and the 2009 License Agreement. The new 2012 agreement and the amendments contain multiple elements, including the license of technology and market access rights, fuel cell kit product deliverables, as well as professional service deliverables. We have identified these three items as deliverables under the multiple-element arrangement guidance and have evaluated the estimated selling prices to be allocated on a relative fair value basis to these deliverables, as vendor-specific objective evidence and third-party evidence was not available. The Company's determination of estimated selling prices involves the consideration of several factors based on the specific facts and circumstances of each arrangement. Specifically, the Company considers the cost to produce the tangible product and professional service deliverables, the anticipated margin on those deliverables, prices charged when those deliverables are sold on a stand-alone basis in limited sales, and the Company's ongoing pricing strategy and practices used to negotiate and price overall bundled product, service and license arrangements. We are amortizing the consideration allocated to the license of technology and market access rights over the 15 year license term on a straight-line basis, and will recognize the amounts allocated to the kit deliverables and professional service deliverables, when such items are delivered to POSCO. We have also determined that based on the utility to the customer of the fully developed technology that was licensed in the Cell Technology Transfer Agreement, there is stand-alone value for this deliverable.

Beginning in fiscal year 2013, license fees and royalty income have been included within revenues on the consolidated statement of operations. This change is a result of the new license agreement entered into on October 31, 2012 for our core technology and the harmonization of the agreements to reflect fees and royalties for the manufacture of complete DFC Power Plants. Classification as revenue is reflective of our Asia market partnership and royalty based strategy and this business activity has become a significant component of non-product revenue and is expected to continue to grow over time.

Revenue from advanced technology contracts is recognized proportionally as costs are incurred and compared to the estimated total advanced technology costs for each contract. Revenue from customer funded advanced technology programs are generally multi-year, cost-reimbursement and/or cost-shared type contracts or cooperative agreements. We are reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract or cooperative agreement, and on certain contracts we are reimbursed only a portion of the costs incurred. While advanced technology contracts may extend for many years, funding is often provided incrementally on a year-by-year basis if contract terms are met and Congress has authorized the funds.

Inventories and Advance Payments to Vendors

Inventories consist principally of raw materials and work-in-process. In certain circumstances, we will make advance payments to vendors for future inventory deliveries. These advance payments are recorded as other current assets on the consolidated balance sheets.

Inventory is reviewed to determine if valuation adjustments are required for obsolescence (excess, obsolete, and slow-moving inventory). This review includes analyzing inventory levels of individual parts considering the current design of our products and production requirements as well as the expected inventory needs for maintenance on installed power plants.

Warranty and Service Expense Recognition

We warranty our products for a specific period of time against manufacturing or performance defects. Our warranty is limited to a term generally 15 months after shipment or 12 months after acceptance of our products, except for fuel cell kits. We have agreed to warranty fuel cell kits and components for 21 months from the date of shipment due to the additional shipping and customer manufacture time required. We reserve for estimated future warranty costs based on historical experience. We also provide for a specific reserve if there is a known issue requiring repair during the warranty period. Estimates used to record warranty reserves are updated as we gain further operating experience. As of April 30, 2013 and October 31, 2012, the warranty reserve, which is classified in accrued liabilities on the consolidated balance sheet, totaled $1.8 million and $2.3 million, respectively.

In addition to the standard product warranty, we have entered into service agreement contracts with certain customers to provide monitoring, maintenance and repair services for fuel cell power plants. Under the terms of our service agreement, the power plant must meet a minimum operating output during the term. If minimum output falls below the contract requirement, we may be subject to performance penalties or may be required to repair or replace the customer's fuel cell stack. The Company has provided for a reserve for performance guarantees of $1.2 million and $2.2 million as of April 30, 2013 and October 31, 2012.

29

The Company provides for reserves on all SA's when the estimated future stack replacements and service costs exceed the remaining contract value. Reserve estimates for future costs on SA's are determined by a number of factors including the estimated remaining life of the stack, used replacement stacks available, our limit of liability on SA's and future operating plans for the power plant. Our reserve estimates are performed on a contract by contract basis and include cost assumptions based on what we anticipate the service requirements will be to fulfill obligations for each contract. As of April 30, 2013 and October 31, 2013, our reserve on service agreement contracts totaled $5.0 million.

At the end of our SA's, customers are expected to either renew the SA or based on the terms of the contract, the stack module will be returned to the Company as the plant is no longer being monitored or having routine service performed. In situations where we do not expect to have a restack during the term, but a restack is required and if the customer agrees at the time of a restack to return the stack to the Company at the end of the SA term, the cost of the stack is recorded as a long-term asset and depreciated over its expected life. If the Company does not obtain rights to title from the customer the cost of the stack is expensed. As of April 30, 2013, the total remaining stack asset value was $12.0 million compared to $14.3 million as of October 31, 2012. As of April 30, 2013, accumulated depreciation on stack assets totaled approximately $9.8 million compared to $7.6 million at October 31, 2012.

During fiscal year 2011, the Company committed to a repair and upgrade program for a select group of 1.2 megawatt (MW) fuel cell modules produced between 2007 and early 2009. As of April 30, 2013, the accrued obligation balance related to this item was $4.7 million compared to $4.8 million as of October 31, 2012.

The Company has completed the repair activities related to the program. The remaining accrued balance is primarily related to modules which are expected to be deployed as field replacements and will be provided to POSCO per the terms of the commitment when needed.

Share-Based Compensation

We account for restricted stock awards (RSA's) and restricted stock units (RSU's) based on the closing market price of the Company's common stock on the date of grant. We account for stock options awarded to employees and non-employee directors under the fair value method of accounting using the Black-Scholes valuation model to estimate fair value at the grant date. The model requires us to make estimates and assumptions regarding the expected life of the option, the risk-free interest rate, the expected volatility of our common stock price and the expected dividend yield. The fair value of equity awards is amortized to expense over the vesting period, generally four years. Share-based compensation expense was $1.0 million and $0.8 million for the six months ended April 30, 2013 and 2012, respectively.

Income Taxes

Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on net operating loss (“NOL”) carryforwards, research and development credit carryforwards, and differences between financial reporting and income tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates and laws expected to be in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded against deferred tax assets if it is unlikely that some or all of the deferred tax assets will be realized.

We apply the guidance regarding how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that the Company has taken or expects to take on a tax return (including a decision whether to file or not file a return in a particular jurisdiction). The company's financial statements reflect expected future tax consequences of such positions presuming the taxing authorities' full knowledge of the position and all relevant facts.

The evaluation of a tax position is a two-step process. The first step is recognition: the company determines whether it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step is measurement: a tax position that meets the “more likely than not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement.

Certain transactions involving the Company's beneficial ownership occurred during the six months ended April 30, 2013 which may result in a stock ownership change for the purposes of Section 382 of the Internal Revenue Code of 1986, as amended. We are in the process of completing a study to determine if any of our NOL and credit carryovers will be subject to limitation. We completed a detailed Section 382 study in fiscal year 2012 to determine if any of our NOL and credit carryovers will be subject to limitation. Based on that study we have determined that there was no ownership change as of October 31, 2012 under Section 382.

ACCOUNTING GUIDANCE UPDATE

Recently Adopted Accounting Guidance

In December 2011, the FASB issued guidance to enhance a financial statement user’s ability to understand the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this guidance includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This guidance also includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. The adoption of this accounting guidance did not have a material impact on our financial position, results of operations or disclosures.

Recent Accounting Guidance Not Yet Effective

None.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Exposure

We typically invest in U.S. treasury securities with maturities ranging from less than three months to one year or more. We typically hold these investments until maturity and accordingly, these investments are carried at cost and not subject to mark-to-market accounting. At April 30, 2013, we had no U.S. treasury investments. 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 at April 30, 2013, including all interest rate sensitive instruments, a change in interest rates of one percent would not have a material impact on our results of operations.

Foreign Currency Exchange Risk

As of April 30, 2013, approximately 3 percent of our total cash, cash equivalents and investments were in currencies other than U.S. dollars (primarily the Euro, Canadian dollars and South Korean Won). 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.

Derivative Fair Value Exposure

Series 1 Preferred Stock

The conversion feature and the variable dividend obligation of our Series 1 Preferred shares are embedded derivatives that require bifurcation from the host contract. The aggregate fair value of these derivatives included within long-term debt and other liabilities as of April 30, 2013 and October 31, 2012 was $0.7 million, respectively. The fair value was based on valuation models using various assumptions including historical stock price volatility, risk-free interest rate and a credit spread based on the yield indexes of technology high yield bonds, foreign exchange volatility as the Series 1 Preferred security is denominated in Canadian dollars, and the closing price of our common stock. Changes in any of these assumptions would change the underlying fair value with a corresponding charge or credit to earnings. However, any changes to these assumptions would not have a material impact on our results of operations.

31

Item 4. CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures, which are designed to provide reasonable assurance that information required to be disclosed in the Company’s periodic SEC reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules 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.

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. Based on that evaluation, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the Company’s periodic SEC reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules 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.

There has been no change in our internal controls over financial reporting that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

32

PART II. OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

We are involved in legal proceedings, claims and litigation arising out of the ordinary conduct of our business. Although we cannot assure the outcome, management presently believes that the result of such legal proceedings, either individually, or in the aggregate, will not have a material adverse effect on our consolidated financial statements, and no material amounts have been accrued in our consolidated financial statements with respect to these matters.

Item 1A. RISK FACTORS

There have been no material changes with respect to the risk factors disclosed in our Annual Report on Form 10-K for the fiscal year ended October 31, 2012.

Recent Accounting Pronouncements

Recently Adopted Accounting Guidance

In December 2011, the FASB issued guidance to enhance a financial statement user’s ability to understand the effects of netting arrangements on an entity’s financial statements, including financial instruments and derivative instruments that are either offset or subject to an enforceable master netting or similar arrangement. The scope of this guidance includes derivatives, sale and repurchase agreements and reverse sale and repurchase agreements, and securities borrowing and securities lending arrangements. This guidance also includes enhanced disclosure requirements, including both gross and net information about instruments and transactions eligible for offset or subject to an agreement similar to a master netting arrangement. The provisions will be applied retrospectively for interim and annual periods beginning on or after January 1, 2013. The adoption of this accounting guidance did not have a material impact on our financial position, results of operations or disclosures.

The majority of advanced technology contracts are with the U.S. Government. We bill the U.S. Government based on actual recoverable costs incurred, typically in the month subsequent to incurring costs. The remainder of advanced technology contracts are billed based on milestones or costs incurred. Included in Commercial Customers accounts receivable are amounts due from POSCO of $10.9 million and $18.1 million at April 30, 2013 and October 31, 2012, respectively.

Acquisitions

Versa Power Systems, Inc. (“Versa”), our wholly-owned subsidiary working under the Department of Energy's (“DOE”) large-scale hybrid project to develop a coal-based, multi-megawatt solid oxide fuel cell (“SOFC”) based hybrid system. Versa has been developing advanced SOFC systems for various stationary and mobile applications since 2001. We had a 39 percent ownership interest and historically accounted for Versa under the equity method of accounting. We recognized our share of the income or losses as income/(loss) from equity investment on the consolidated statements of operations.

On December 20, 2012, the Company acquired the remaining 61 percent ownership position of Versa in a stock transaction by exchanging approximately 3.5 million shares of its common stock for the outstanding Versa shares held by the other Versa shareholders.

The transaction has been accounted for using the acquisition method of accounting which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. Step-acquisition accounting guidance was applied and an impairment charge of $3.6 million relating to the previously held equity investment was recorded in the fourth quarter of 2012.

The following table summarizes the allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed as of the acquisition date. This allocation is preliminary and the Company is still in the process of analyzing and evaluating the acquired deferred tax attributes of Versa, if any.  Completion of this review may result in adjustments to the deferred tax attributes and amounts recorded as a result of this acquisition.

Acquisition-related costs of $0.1 million were expensed as incurred. These costs were recognized in administrative and selling expenses on the statement of operations and comprehensive income for the six months ended April 30, 2013.

Versa has been fully consolidated into the Company's financial statements as of the acquisition date. Versa receives revenue under a number of research contracts including the U.S. Department of Energy Solid State Energy Conversion Alliance (SECA) coal-based systems program and a research contract with The Boeing Company. Revenue and associated costs are recognized under advanced technologies contract revenues in the consolidated statements of operations.

The decrease in the reserve for performance guarantees penalties was due to certain amounts being reclassed to accounts payable due to the finalization of negotiations of amounts due to POSCO.

Share-Based Compensation Plans

Share-Based Compensation Plans

We have shareholder approved equity incentive plans and a shareholder approved Section 423 Stock Purchase Plan (the “ESPP”). We account for stock awards to employees and non-employee directors under the fair value method. We determine the fair value of stock options at the grant date using the Black-Scholes valuation model. The model requires us to make estimates and assumptions regarding the expected life of the award, the risk-free interest rate, the expected volatility of our common stock price and the expected dividend yield. The fair value of restricted stock units ("RSU") and restricted stock awards (“RSA”) is based on the common stock price on the date of grant. The fair value of stock awards is amortized to expense over the vesting period, generally four years.

Share-based compensation reflected in the consolidated statements of operations were as follows:

	Three Months Ended April 30,				Six Months Ended April 30,
	2013		2012		2013		2012
Costs of revenues	$	149	$	93	$	281	$	253
General and administrative expenses	282		160		597		457
Research and development expenses	79		49		139		132
Total share-based compensation	$	510	$	302	$	1,017	$	842

The following table summarizes stock option activity for the six months ended April 30, 2013:

	Number of options		Weighted average option  price ($)
Outstanding at October 31, 2012	3,120,456		6.96
Granted	279,746		0.94
Canceled	(178,663	)	6.32
Outstanding at April 30, 2013	3,221,539		6.47

As of April 30, 2013, there were 5,127,626 RSA's and RSU's outstanding with a weighted average per share fair value of $1.19. There were 905,645 RSA's and RSU's granted during the six months ended April 30, 2013 and forfeitures totaled 1,850 during this period. During the second quarter of fiscal year 2013, the Company established an international award program to include RSU's for the benefit of certain employees outside the United States.

For the six months ended April 30, 2013, 108,008 shares were issued under the ESPP at a per share cost of $0.79. There were 666,365 shares of common stock reserved for issuance under the ESPP as of April 30, 2013.

Nature of Business and Basis of Presentation

FuelCell Energy, Inc. and subsidiaries (the “Company”, “FuelCell Energy”, “we”, “us”, or “our”) is a leading integrated fuel cell company with a growing global presence. We design, manufacture, install, operate and service ultra-clean, efficient and reliable stationary fuel cell power plants. Our Direct FuelCell power plants produce reliable 24/7 base load electricity and usable high quality heat for commercial, industrial, government and utility customers. We have commercialized our stationary carbonate fuel cells and are also pursuing the complementary development of planar solid oxide fuel cell and other fuel cell technologies. We continue to invest in new product and market development and, as such, we are not currently generating positive cash flow from our operations.  Our operations are funded primarily through cash generated from product sales, service and advanced technologies contracts, license fee income and sales of equity and debt securities. In order to produce positive cash flow from operations, we need to be successful at increasing annual order volume, production and cost reduction efforts.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) 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 (“GAAP”) for complete financial statements. In the opinion of management, all normal and recurring adjustments necessary to fairly present our financial position as of April 30, 2013 have been included. All intercompany accounts and transactions have been eliminated.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted.  The balance sheet as of October 31, 2012 has been derived from the audited financial statements at that date, but it does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.These financial statements should be read in conjunction with our financial statements and notes thereto for the year ended October 31, 2012, which are contained in our Annual Report on Form 10-K previously filed with the Securities and Exchange Commission.  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 year.

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation. Service agreement revenue has been separated from Product sales as current year service agreement revenue exceeds the ten percent threshold of Regulation SX Rule 3-05 and revenues and is now combined with license revenue. Beginning in fiscal year 2013, license fees and royalty income have been included within revenues. This change is a result of the new license agreement entered into on October 31, 2012 for our core technology and the harmonization of the agreements to reflect fees and royalties for the manufacture of complete DFC Power Plants. Classification of license fees and royalty income as revenue is reflective of our Asia market partnership and royalty based strategy having become a significant component of non-product revenue. Additionally, Advanced technologies contract revenues has been renamed from Research and development contracts to better describe the sources of revenue from contract research.

The Company has corrected the presentation of restricted cash balances which had been previously included in cash and cash equivalents. As of October 31, 2012, short-term and long-term restricted cash balances in the amount of $5.3 million and $5.3 million, respectively, have been reclassified to short-term and long-term restricted cash. This revision also impacted net cash used in financing activities. There was no impact on net loss or net cash used in operating activities as a result of the revision.

Use of Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the U.S. 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, excess, slow-moving and obsolete inventories, product warranty costs, reserves on service agreements ("SA"), allowance for uncollectible receivables, depreciation and amortization, impairment of assets, taxes, 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.

Concentrations

We contract with a concentrated number of customers for the sale of products, service and advanced technologies contracts. Significant revenues from individual customers for the three and six months ended April 30, 2013 and 2012 included POSCO Energy (“POSCO”), which is a related party and owns approximately 16 percent of the outstanding common shares of the Company as of April 30, 2013, Dominion Bridgeport Fuel Cell, LLC and the U.S. Government (primarily the Department of Energy).

The percent of consolidated revenues from each customer is presented below.

Note 9. Share-Based Compensation Plans [Abstract]

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

We have shareholder approved equity incentive plans and a shareholder approved Section 423 Stock Purchase Plan (the “ESPP”). We account for stock awards to employees and non-employee directors under the fair value method. We determine the fair value of stock options at the grant date using the Black-Scholes valuation model. The model requires us to make estimates and assumptions regarding the expected life of the award, the risk-free interest rate, the expected volatility of our common stock price and the expected dividend yield. The fair value of restricted stock units ("RSU") and restricted stock awards (“RSA”) is based on the common stock price on the date of grant. The fair value of stock awards is amortized to expense over the vesting period, generally four years.
