FuelCell Energy Reports Third Quarter of Fiscal 2023 Results

Third Quarter Fiscal 2023 Financial Highlights

(All comparisons are year-over-year unless otherwise noted)

●	Revenues of $25.5 million compared to $43.1 million

●	Gross loss of $(8.2) million compared to $(4.2) million

●	Loss from operations of $(41.4) million compared to $(28.0) million

DANBURY, CT – September 11, 2023 – FuelCell Energy, Inc. (Nasdaq: FCEL) -- a global leader in decarbonizing power and producing hydrogen through its proprietary, state-of-the-art fuel cell platforms to enable a world empowered by clean energy -- today reported financial results for its third quarter ended July 31, 2023.

“For the third quarter of fiscal year 2023, reported revenues were down versus the comparable prior year quarter. This was primarily a result of lower product revenues due to the lack of module sales compared to sales in the comparable prior year quarter of replacement modules to Korea Fuel Cell Co., Ltd. (“KFC”)” said Mr. Jason Few, President and Chief Executive Officer. “Excluding the revenues generated by the sale of modules to KFC in the prior year quarter, overall revenues in the third quarter were up slightly compared to the prior year quarter.”

“We were extremely pleased to announce that we have completed the commissioning of the Toyota Long Beach project, and that our Tri-gen platform is producing power, water and hydrogen that meets the stringent purity specifications required for mobility applications,” added Mr. Few. “At this time, we are only waiting on the receipt of the final fire department and related building permits required to fully declare achievement of commercial operations. This marks a significant accomplishment in our technology development in partnership with Toyota. We believe that our innovative Tri-gen system will help Toyota achieve its decarbonization goals by producing emissions-free hydrogen, electricity, and water every day. We are excited to explore opportunities to apply our Tri-gen technology to additional projects in the future.”

Mr. Few continued, “We extended the term of our Joint Development Agreement with ExxonMobil Technology and Engineering Company (“EMTEC”) through March 2024 to allow us to continue to derisk our Generation 2 Technology fuel cell module demonstration prototype and continue our joint marketing and sales efforts to inform development of a new business framework between the parties beyond the current joint development agreement structure. We look forward to the expected future commercialization of this important technology, which we believe will demonstrate the ability of our technology to help address one of the world’s largest environmental challenges. And, on the project construction front, both projects in Derby, Connecticut being constructed are advancing on schedule, and we are on track to achieve commercial operations on the combined 16.8-megawatt (“MW”) installations in the fourth quarter of calendar year 2023.”

Mr. Few added, “Also during the third quarter, we were very pleased to expand our presence in the Korean market with domestic clean energy electric utilities that had previously installed

FuelCell Energy Third Quarter Fiscal 2023 Results ‌ Page 2

FuelCell Energy power platforms. We executed a long-term service agreement with Noeul Green Energy Co., Ltd. (“Noeul Green”) and a memorandum of understanding with Gyeonggi Green Energy Co., Ltd., and are delighted to have the opportunity to help support stable fuel cell operations and advance eco-friendly power generation in Korea. The 14-year long-term service agreement with Noeul Green has added expected significant long-term recurring revenue to our reported backlog, with a contract value of approximately $73 million.”

“We ended the quarter on July 31, 2023 with a total cash and short-term investment position of approximately $414 million,” added Mr. Few. “During the quarter, we added liquidity to our balance sheet by entering into an $80.5 million non-recourse project financing facility through a multi-bank financing agreement with Investec Bank plc, Bank of Montreal (Chicago Branch), Connecticut Green Bank, Liberty Bank and Amalgamated Bank. The net proceeds from this transaction added approximately $46.1 million to the Company’s unrestricted cash position after repayment of existing project debt obligations and partial repayments of corporate debt obligations, and the related release of certain reserves in connection with such repayments. In addition, we were able to further support our liquidity through sales of shares under our at-the-market offering program, which raised net proceeds of approximately $83.3 million during the quarter.”

Mr. Few concluded, “We continue to execute on our strategy, proving our technologies in critical applications and supporting decarbonization across the globe. We believe that strong and growing demand for clean energy technologies combined with government policy support has generated significant potential in our markets.”

Third Quarter of Fiscal 2023 Results

Note: All comparisons between periods are between the third quarter of fiscal 2023 and the third quarter of fiscal 2022, unless otherwise specified.

Third quarter revenues of $25.5 million represent a decrease of 41% from the comparable prior year quarter primarily due to lower product revenues. A breakdown of revenues for the quarter compared to the comparable prior year quarter follows.

●	Product revenues for the prior year quarter included module sales to KFC, for which the Company recognized $18.0 million compared to no product revenue recorded for the third quarter of fiscal 2023.

FuelCell Energy Third Quarter Fiscal 2023 Results ‌ Page 3

●

Service agreements revenues increased to $9.8 million from $9.0 million. The increase in service agreements revenues for the third quarter of fiscal 2023 was primarily driven by two new module exchanges at the plant owned by Korea Southern Power Company in Korea, which achieved commercial operations in fiscal year 2018, and a module exchange at the plant at Trinity College.

●	Generation revenues were consistent period over period, increasing to $11.0 million from $10.9 million in the prior year period.

●

Advanced Technologies contract revenues decreased to $4.7 million from $5.2 million. Compared to the third quarter of fiscal 2022, Advanced Technologies contract revenues recognized under the Joint Development Agreement with EMTEC were approximately $0.3 million higher during the third quarter of fiscal 2023 and revenue recognized under government and other contracts were approximately $0.8 million lower during the third quarter of fiscal 2023 as a result of the allocation of engineering resources during the quarter.

Gross loss for the third quarter of fiscal 2023 totaled $8.2 million, compared to a gross loss of $4.2 million in the comparable prior year quarter. The gross loss increased for the third quarter of fiscal 2023 primarily due to the fact that there were no module sales during the quarter, compared to the third quarter of fiscal 2022, which included favorable product margins as a result of the module sales to KFC.

Operating expenses for the third quarter of fiscal 2023 increased to $33.2 million from $23.8 million in the third quarter of fiscal 2022. Administrative and selling expenses were higher during the third quarter of fiscal 2023 compared to the third quarter of fiscal 2022, primarily due to an increase in compensation expense resulting from an increase in headcount in support of sales and business expansion. Research and development expenses increased to $15.6 million during the third quarter of fiscal 2023 compared to $9.7 million in the third quarter of fiscal 2022. The increase in research and development expenses is primarily due to an increase in spending on the Company’s ongoing commercial development efforts related to our solid oxide power generation and electrolysis platforms and carbon separation and carbon capture solutions compared to the comparable prior year period.

Net loss was $23.6 million in third quarter of fiscal 2023, compared to net loss of $29.0 million in the third quarter of fiscal 2022.

Adjusted EBITDA totaled $(31.6) million in the third quarter of fiscal 2023, compared to Adjusted EBITDA of $(20.8) million in the third quarter of fiscal 2022. Please see the discussion of non-GAAP financial measures, including Adjusted EBITDA, in the appendix at the end of this release.

The net loss per share attributable to common stockholders in the third quarter of fiscal 2023 was $0.06, compared to $0.08 in the third quarter of fiscal 2022.

Operations Update

In-flight projects: During the quarter, the Company continued to make progress on projects for which we have executed power and/or hydrogen purchase agreements, with updates regarding certain current projects provided below.

Toyota - Port of Long Beach, CA. This 2.8 MW Tri-gen platform produces electricity (at a net output of 2.3 MW), hydrogen and water. The Company has successfully completed the commissioning of this platform, and it is producing power and water and delivering hydrogen that meets the stringent purity specifications required for mobility applications. The plant is currently operating and, at this time, we are only waiting on the receipt of the final fire department and related building permits required to fully declare achievement of commercial operations.

Derby, CT. On-site construction of this 14.0 MW project continues to advance and the Company has largely completed the construction and installation of the majority of the balance of plant components on site as well as all ten modules required for the project. This utility scale fuel cell platform will contain five SureSource 3000 fuel cell systems that will be installed on engineered platforms alongside the Housatonic River. To date, the Company has invested approximately $52.9 million into the project, and our current expectation is that this project will commence commercial operations in the fourth calendar quarter of 2023.

In addition, the on-site civil construction of the 2.8 MW project located in Derby, CT is advancing. Our current expectation is that this project will also commence commercial operations in the fourth calendar quarter of 2023.

FuelCell Energy Third Quarter Fiscal 2023 Results ‌ Page 5

Trinity College. During fiscal year 2022, we entered into a power purchase agreement with Trinity College in Hartford, Connecticut, for our 250 kW solid oxide fuel cell power generation system. Power and heat produced from the platform will be used at Trinity’s campus in Hartford, Connecticut, to lower energy cost and enhance energy reliability and security. This project is currently under development and the solid oxide fuel cell power generation system is expected to be installed in the summer of 2024. Modules for our solid oxide platform are manufactured at our manufacturing and research and development facility in Calgary, Alberta, Canada, and the project will be fully assembled and integrated at our facilities in Connecticut.

Manufacturing Output, Capacity and Expansion: We have made progress in advancing our carbonate and solid oxide platform capacity expansion plans.

Carbonate Platform: During the nine months ended July 31, 2023, we operated at an annualized production rate of approximately 31.9 MW, compared to an annualized production rate for the nine months ended July 31, 2022 of 38.5 MW. This reduction in annualized production rate is primarily due to reduced staffing levels in our Torrington facility. The Company continuously evaluates its production rate and staffing levels and has determined that the current levels are sufficient to satisfy the current demand for carbonate fuel cell modules.

The Company continues to invest in capability with the goal of reducing production bottlenecks and driving productivity, including investments in automation, laser welding, and the construction of additional integrated conditioning capacity. The Company also constructed a SureSource 1500 in Torrington during fiscal year 2022, which operates as a testing facility for qualifying new supplier components and performance testing and validation of continued platform innovations. During fiscal year 2023, the Company is investing to add engineered carbon separation capability to the onsite SureSource 1500. This product enhancement will allow potential customers to observe the operating plant and, given the targeted market of food and beverage companies, will allow for the sampling and testing of separated CO₂ to verify quantity, quality or purity requirements.

Solid Oxide Platform: The Company continues to invest in product development and manufacturing scale up for two solid oxide platforms: power generation and electrolysis. Both platforms are based on the Company’s differentiated thin, lightweight, electrode supported cells, which are configured into compact, lightweight stacks. The thin electrode structure minimizes electrolyte materials, leading to very low use of rare earth minerals compared to other solid oxide technologies, and the electrodes do not require the platinum group materials that lower temperature systems require. The thin electrodes also have very low electrical resistance, leading to high efficiency in both power generation and electrolysis applications. We provide integrated products with the goal of offering complete customer solutions. Our electrolysis platform includes integrated steam generation and hydrogen drying systems, so it will be fed with water, not steam, and will provide dried hydrogen. A steam supply can optionally be used to increase the electrical efficiency of the system from 90% to 100% (based on higher heating value). Our power generation platform can operate on natural gas, biogas, hydrogen, or fuel blends, and is capable of combined heat and power operation at up to 80% efficiency (based on lower heating value).

During the nine months ended July 31, 2023, Versa Power Systems Ltd. (“Versa Ltd.”), a subsidiary of FuelCell Energy, entered into a lease expansion, extension and amending agreement which expanded the space leased by Versa Ltd. in Calgary, Alberta, Canada to include an additional approximately 48,000 square feet, for a total of approximately 80,000

FuelCell Energy Third Quarter Fiscal 2023 Results ‌ Page 6

square feet of space. The Company took possession of part of the additional space on April 1, 2023 and took possession of the rest of the additional space on June 1, 2023 after certain leasehold improvements were made to support increased manufacturing. In addition, long-lead process equipment has been ordered to facilitate the expansion of manufacturing capacity for the solid oxide platforms in Calgary. Upon the completion of the Calgary capacity expansion, the Company expects that it will be able to increase annual production capacity and that it will be capable of delivering up to 40 MW of annualized solid oxide electrolysis cell (“SOEC”) production per year. During the engineering and permitting phase of this initial manufacturing expansion project, the Company has designed in flexibility that would allow us to further increase the cell stack manufacturing capacity at our Calgary facility to facilitate the potential annualized production of up to an additional 40 MW of SOECs per year by leasing additional space and investing in various process optimizations intended to increase throughput and yield. This approach would allow for the potential to increase our total annualized SOEC manufacturing capacity to up to 80 MW per year. Additional investments in our Torrington, CT manufacturing facility could also be undertaken to provide solid oxide module assembly to further enhance overall SOEC manufacturing capacity. The Company has hired and trained additional staff for a 3-shift production operation to support the initial planned expansion to 40 MW and would need to add additional staff as required in the future to realize the potential 80 MW of annualized SOEC production.

During calendar year 2023, our Calgary manufacturing operation was expected to build and deliver four units: two units that will run internally for advanced testing and two production units for delivery externally. Of these commercial units for external delivery, one will be our electrolysis platform for delivery to Idaho National Laboratory (“INL”), and the other will be our distributed power platform for delivery to Trinity College in Hartford, Connecticut for use under a long-term power purchase agreement. All four of these units are in the design, fabrication or manufacturing process, with the INL unit expected to be operational in late calendar year 2023. The other three units are expected to be completed and delivered during calendar year 2024 depending on timing of site readiness, permitting and key component deliveries. If needed to accommodate future commercial orders, the Company may reallocate one or more of its planned internal units for commercial delivery.

The expansion of the Calgary manufacturing facility is phase 1 of the Company’s planned operational expansion of production capability. While this expansion is expected to increase our production capacity from 4 MW per year to 40 MW per year of SOECs, the Company also plans to add an additional 400 MW of solid oxide manufacturing capacity in the United States. Early facility design and engineering requirements have been developed, and the Company has engaged in an extensive search in the United States for a potential location for a new manufacturing facility, which would be incremental to the Calgary facility. We anticipate announcing more details regarding our plans for solid oxide production expansion into the United States later in the near term.

Lastly, the Company is in the process of examining or actively applying for various financial programs offered by both Canada and the United States to provide subsidies, investment tax credits and other assistance with the goal of expanding capacity for clean energy manufacturing.

Backlog


	As of July 31,
(Amounts in thousands)	2023		2022		Change
Product	$	26	$	38,312	$	(38,286)
Service		136,621		112,238		24,383
Generation		915,062		1,103,396		(188,334)
Advanced Technologies		11,552		30,217		(18,665)
Total Backlog	$	1,063,261	$	1,284,163	$	(220,902)

Overall backlog decreased by approximately 17.2% to $1.06 billion as of July 31, 2023, compared to $1.28 billion as of July 31, 2022, as a result of a reduction in generation backlog due to the decision to not move forward with certain generation projects during the fourth quarter of fiscal 2022, and also due, in part, to the timing of revenue recognition under Product, Generation and Service agreements since July 31, 2022. This decline was partially offset by the new service agreement with Noeul Green entered into during the three months ended July 31, 2023.

Backlog represents definitive agreements executed by the Company and our customers. Projects for which we have an executed power purchase agreement (“PPA”) or hydrogen power purchase agreement (“HPPA”) are included in generation backlog, which represents future revenue under long-term PPAs and HPPAs. The Company’s ability to recognize revenue in the future under a PPA or HPPA is subject to the Company’s completion of construction of the project covered by such PPA or HPPA. Should the Company not complete the construction of the project covered by a PPA or HPPA, it will forgo future revenues with respect to the project and may incur penalties and/or impairment charges related to the project. Projects sold to customers (and not retained by the Company) are included in product sales and service agreements backlog, and the related generation backlog is removed upon sale. Together, the service and generation portion of backlog had a weighted average term of approximately 17 years, with weighting based on the dollar amount of backlog and utility service contracts of up to 20 years in duration at inception.

Appendix

Non-GAAP Financial Measures

Financial results are presented in accordance with accounting principles generally accepted in the United States (“GAAP”). Management also uses non-GAAP measures to analyze and make operating decisions on the business. Earnings before interest, taxes, depreciation and amortization (“EBITDA”) and Adjusted EBITDA are non-GAAP measures of operations and operating performance by the Company.

These supplemental non-GAAP measures are provided to assist readers in assessing operating performance. Management believes EBITDA and Adjusted EBITDA are useful in assessing performance and highlighting trends on an overall basis. Management also believes these measures are used by companies in the fuel cell sector and by securities analysts and investors when comparing the results of the Company with those of other companies. EBITDA differs from the most comparable GAAP measure, net loss attributable to the Company, primarily because it does not include finance expense, income taxes and depreciation of property, plant and equipment and project assets. Adjusted EBITDA adjusts EBITDA for stock-based compensation, restructuring charges and other unusual items such as the non-recurring legal expense related to the settlement of the POSCO Energy legal proceedings recorded during the first quarter of fiscal 2022, which are considered either non-cash or non-recurring.

While management believes that these non-GAAP financial measures provide useful supplemental information to investors, there are limitations associated with the use of these measures. The measures are not prepared in accordance with GAAP and may not be directly comparable to similarly titled measures of other companies due to potential differences in the exact method of calculation. The Company’s non-GAAP financial measures are not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP.

The following table calculates EBITDA and Adjusted EBITDA and reconciles these figures to the GAAP financial statement measure Net loss.
