**DANBURY, Conn., September 9, 2025** (GLOBE NEWSWIRE) -- FuelCell Energy, Inc. (NASDAQ: FCEL) today reported financial results for its third quarter ended July 31, 2025.

"In our third fiscal quarter, we delivered meaningful revenue growth while advancing execution of our long-term strategy," said Jason Few, President and Chief Executive Officer. "We improved our core carbonate platform by increasing efficiency above 50% and focused on working to expand our opportunities in distributed generation and deepen our sales pipeline by leveraging our large-scale deployments to engage prospective data center customers.

**Third Quarter of Fiscal 2025 Results**

*(All comparisons are between third quarter of fiscal 2025 and third quarter of fiscal 2024 unless otherwise noted)*

Third quarter revenue of $46.7 million represents an increase of 97% from the comparable prior year

quarter.

● **Product** revenues were $26.0 million compared to $0.3 million in the comparable prior year period. The increase was primarily driven by $24.0 million of revenue recognized under the Company's long-term service agreement with Gyeonggi Green Energy Co., Ltd. ("GGE") for the delivery and commissioning of eight fuel cell modules for GGE's 58.8 MW fuel cell power plant platform in Hwaseong-si, Korea, and $2.0 million of revenue recognized under the Company's sales contract with Ameresco, Inc.

● **Service agreements** revenues increased to $3.1 million from $1.4 million. The increase in service agreements revenues during the three months ended July 31, 2025 was primarily driven by revenue recognized under the Company's long-term service agreement with GGE for service provided by the Company to GGE's 58.8 MW fuel cell power plant platform in Hwaseong-si, Korea.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

● **Generation** revenues decreased to $12.4 million from $13.4 million. The decrease in generation revenues for the three months ended July 31, 2025 reflects lower output from plants in the Company's generation operating portfolio resulting from routine maintenance activities during the quarter.

● **Advanced Technologies** contract revenues decreased to $5.3 million from $8.6 million. Advanced Technologies contract revenues recognized under our Joint Development Agreement with ExxonMobil Technology and Engineering Company ("EMTEC") were approximately $3.1 million, revenues arising from the purchase order received from Esso Nederland B.V. ("Esso"), an affiliate of EMTEC and Exxon Mobil Corporation, related to the Rotterdam project were approximately $1.4 million and revenue recognized under government contracts and other contracts were approximately $0.8 million for the three months ended July 31, 2025. This compares to Advanced Technologies contract revenues recognized under our Joint Development Agreement with EMTEC of approximately $1.8 million, revenue recognized under the Esso purchase order of approximately $3.5 million and revenue recognized under government contracts and other contracts of approximately $3.3 million for the three months ended July 31, 2024.

Gross loss for the third quarter of fiscal 2025 totaled $(5.1) million, compared to a gross loss of $(6.2) million in the comparable prior year quarter. The decrease in gross loss for the third quarter of fiscal 2025 was primarily related to decreased gross loss from generation revenues and product revenues, partially offset by reduced gross margin on Advanced Technologies contract revenues and service agreements revenues during the third quarter of fiscal 2025.

Operating expenses for the third quarter of fiscal 2025 increased to $90.2 million from $27.4 million in the third quarter of fiscal 2024, primarily due to non-cash impairment expenses of $64.5 million and restructuring expenses of $4.1 million recognized in third quarter of fiscal 2025, compared to no such expenses in the third quarter of fiscal 2024.

Administrative and selling expenses decreased to $14.1 million during the third quarter of fiscal 2025 from $14.6 million during the third quarter of fiscal 2024. The decrease in administrative and selling expenses is primarily due to lower compensation expense resulting from the restructuring actions taken in September 2024, November 2024, and June 2025.

Research and development expenses decreased to $7.6 million during the third quarter of fiscal 2025 compared to $12.8 million in the third quarter of fiscal 2024. The decrease in research and development expenses is primarily due to a decrease in spending on the Company's commercial development efforts related to our solid oxide power generation and electrolysis platforms and carbon separation and carbon recovery solutions compared to the comparable prior year period.

In connection with our June 2025 restructuring plan, the Company evaluated certain asset groups for impairment in the third quarter of fiscal 2025. As a result of this analysis, the Company recorded total non-cash impairment expenses of $64.5 million, consisting of approximately $42.1 million related to property, plant and equipment, approximately $9.0 million related to inventory, approximately $9.3 million related to in-process research and development intangible assets, and approximately $4.1 million related to goodwill.

------

Net loss was $(91.9) million in the third quarter of fiscal 2025, compared to net loss of $(35.1) million in the third quarter of fiscal 2024.

Net loss attributable to common stockholders was $(92.5) million in the third quarter of fiscal 2025, compared to net loss attributable to common stockholders $(33.5) million in the third quarter of fiscal 2024.

Adjusted EBITDA totaled $(16.4) million in the third quarter of fiscal 2025, compared to Adjusted EBITDA of $(20.1) million in the third quarter of fiscal 2024. Adjusted net loss attributable to common stockholders totaled $(23.2) million in the third quarter of fiscal 2025, compared to Adjusted net loss attributable to common stockholders of $(29.2) million in the third quarter of fiscal 2024. Please see the discussion of non-GAAP financial measures, including Adjusted EBITDA and Adjusted net loss attributable to common stockholders, in the appendix at the end of this release. We believe that this improvement in Adjusted EBITDA and Adjusted net loss attributable to common stockholders reflects the early benefits of our cost-saving actions and our sharper focus on our core carbonate platform under our restructuring plan.

The net loss per share attributable to common stockholders in the third quarter of fiscal 2025 was $(3.78), compared to $(1.99) in the third quarter of fiscal 2024. The increase in net loss per share attributable to common stockholders is primarily due to the non-cash impairment expenses and restructuring expenses recognized during the third quarter of fiscal 2025, partially offset by the benefit of the higher number of weighted average shares outstanding due to share issuances since July 31, 2024. Non-cash impairment expenses and restructuring expenses negatively impacted net loss per share attributable to common stockholders by $(2.80) for the third quarter of fiscal 2025 and, excluding these expenses and other non-cash expenses, Adjusted net loss per share attributable to common stockholders in the third quarter of fiscal 2025 was $(0.95). Please see the discussion of non-GAAP financial measures, including Adjusted net loss per share attributable to common stockholders, in the appendix at the end of this release.

**Cash, Restricted Cash and Short-Term Investments**

Cash and cash equivalents, restricted cash and cash equivalents, and short-term investments totaled $236.9 million as of July 31, 2025, compared to $318.0 million as of October 31, 2024. Of the $236.9 million as of July 31, 2025, unrestricted cash and cash equivalents totaled $174.7 million and restricted cash and cash equivalents totaled $62.2 million. Of the $318.0 million total as of October 31, 2024, unrestricted cash and cash equivalents totaled $148.1 million, short-term investments totaled $109.1 million and restricted cash and cash equivalents totaled $60.8 million. Short-term investments represented the amortized cost of U.S. Treasury Securities outstanding and held by the Company as of October 31, 2024.

During the three months ended July 31, 2025, approximately 6.8 million shares of the Company's common stock were sold under the Company's Open Market Sale Agreement, as amended, at an average sale price of $5.70 per share, resulting in gross proceeds of approximately $39.0 million before deducting sales commissions and fees, and net proceeds to the Company of approximately $38.1 million after deducting sales commissions and fees totaling approximately $0.9 million. Subsequent to

------

the end of the quarter, approximately 2.7 million shares of the Company's common stock were sold under the Company's Open Market Sale Agreement, as amended, at an average sale price of $4.55 per share, resulting in gross proceeds of approximately $12.1 million before deducting sales commissions and fees, and net proceeds to the Company of approximately $11.8 million after deducting sales commissions and fees totaling approximately $0.3 million.

---

Overall, backlog increased by approximately 4.0% to $1.24 billion as of July 31, 2025, compared to $1.20 billion as of July 31, 2024, primarily as a result of the Hartford Project (as defined below), the long term service agreement ("LTSA") with CGN-Yulchon Generation Co., Ltd. ("CGN") with respect to CGN's Yulchon facility in Korea (the "CGN Platform") and the LTSA with GGE (the "GGE LTSA") with respect to GGE's 58.8 MW fuel cell power platform in Hwaseong-si, Korea (the "GGE Platform"). Backlog by revenue category is as follows:

● Service agreements backlog totaled $169.4 million as of July 31, 2025, compared to $178.4 million as of July 31, 2024. Service agreements backlog includes future contracted revenue from maintenance and scheduled module exchanges for power plants under service agreements. During the three months ended July 31, 2025, the Company entered into a LTSA with CGN (the "CGN LTSA") for the CGN Platform. The contract value of the CGN LTSA totaled approximately $31.7 million, of which approximately $7.7 million was allocated to service backlog at the time of the execution of the CGN LTSA and will be recognized as revenue as the Company performs service at the CGN Platform over the term of the CGN LTSA. During the fourth quarter of fiscal year 2024, the Company entered into the GGE LTSA with respect to the GGE Platform. The contract value of the GGE LTSA totaled approximately $159.6 million, of which approximately $33.6 million was allocated to service backlog at the time of the execution of the GGE LTSA and is being recognized as revenue as the Company performs service at the GGE Platform over the term of the GGE LTSA.

● Generation backlog totaled $955.0 million as of July 31, 2025, compared to $839.5 million as of July 31, 2024. Generation backlog represents future contracted energy sales under power purchase agreements ("PPAs") or approved utility tariffs. During the nine months ended July 31, 2025, the Company entered into a 20-year PPA with Eversource and United Illuminating, pursuant to which the Company will build and operate a 7.4 MW carbonate fuel cell power plant in Hartford, Connecticut (the "Hartford Project"). The electricity generated by the plant will be sold to Eversource and United Illuminating. The revenue over the contract term is expected to total approximately $167.4 million, which has been added to Generation backlog.

● Product backlog totaled $96.2 million as of July 31, 2025, compared to $136.7 million as of July 31, 2024. Product backlog decreased during the period ended July 31, 2025 primarily as a result of the product backlog that was recognized as revenue as the Company completed commissioning of replacement modules for the GGE Platform. Under the GGE LTSA, commissioning of the first six 1.4-MW replacement fuel cell modules was completed in the fourth quarter of fiscal year 2024, and commissioning of an additional twelve 1.4-MW

------

replacement fuel cell modules was completed in the first nine months of fiscal year 2025. An additional eight 1.4-MW replacement fuel cell modules are expected to be commissioned throughout the remainder of fiscal year 2025, and the remaining 16 1.4-MW replacement fuel cell modules are expected to be commissioned in fiscal year 2026. Partially offsetting this decrease was the CGN LTSA, which added $24.0 million to product backlog during the third quarter of fiscal year 2025.

● Advanced Technologies contract backlog totaled $24.3 million as of July 31, 2025, compared to $42.5 million as of July 31, 2024. Advanced Technologies contract backlog primarily represents remaining revenue under our Joint Development Agreement with EMTEC, revenue under a purchase order from Esso valued at $15.6 million (which includes a $4.0 million increase due to two change orders executed during the first nine months of fiscal year 2025), and remaining revenue under our government contracts.

The CGN Platform is comprised of four SureSource 3000 molten carbonate fuel cells (each a "CGN Plant"). Each CGN Plant is comprised of two carbonate fuel cell modules. Pursuant to the CGN LTSA, CGN and the Company have agreed that (i) CGN will purchase from the Company eight carbonate fuel cell modules to replace existing fuel cell modules at the CGN Platform, (ii) the Company will provide certain balance of plant replacement components if and to the extent the parties reasonably determine existing components should be replaced, and (iii) the Company will provide long term operations and maintenance services for the CGN Platform. The total amount payable by CGN under the CGN LTSA for the eight replacement fuel cell modules, balance of plant replacement components, and service is $31.7 million USD, with payments to be made over time as such replacement fuel cell modules are commissioned and the service obligations under the CGN LTSA for such CGN Plants commence. This amount was recorded as backlog concurrent with the execution of the CGN LTSA on July 30, 2025.

The GGE Platform is comprised of 21 SureSource 3000 molten carbonate fuel cells (each a "GGE Plant"). Each GGE Plant is comprised of two 1.4-MW carbonate fuel cell modules. Pursuant to the GGE LTSA, GGE and the Company have agreed that (i) GGE will purchase from the Company 42 1.4-MW carbonate fuel cell modules to replace existing fuel cell modules at the GGE Platform, (ii) the Company will provide certain balance of plant replacement components if and to the extent the parties reasonably determine existing components should be replaced, and (iii) the Company will provide long term operations and maintenance services for the GGE Platform. The total amount payable by GGE under the GGE LTSA for the 42 replacement fuel cell modules, balance of plant replacement components, and service was $159.6 million USD, with payments being made and to be made over time as such replacement fuel cell modules are commissioned and the service obligations under the GGE LTSA for such GGE Plants commence. This amount was recorded as backlog concurrent with the execution of the GGE LTSA on May 28, 2024, and has since been reduced as revenue has been recognized under the GGE LTSA which commenced in the fourth quarter of fiscal year 2024.

Backlog represents definitive agreements executed by the Company and our customers. Projects for which we have an executed PPA are included in generation backlog, which represents future revenue under long-term PPAs. The Company's ability to recognize revenue in the future under a PPA is subject to the Company's completion of construction of the project covered by such PPA. Should the Company not complete the construction of the project covered by a PPA, it will forgo future revenues with respect to the project and may incur penalties and/or impairment expenses 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 16 years as of July 31,

------

2025, 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"), Adjusted EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders 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, Adjusted EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders 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, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, which are considered either non-cash or non-recurring. Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders differ from the most comparable GAAP measures, Net loss attributable to common stockholders and Net loss per share attributable to common stockholders, primarily because they do not include stock-based compensation, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes depreciation and amortization on our Generation portfolio of $7.7 million and $24.4 million for the three and nine months ended July 31, 2025, respectively, and $7.3 million and $21.3 million for the three and nine months ended July 31, 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) Other (income) expense, net includes gains and losses from transactions denominated in foreign currencies, interest rate swap income earned from investments and other items incurred periodically, which are not the result of the Company's normal business operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) The Company recorded a mark-to-market net gain of $1.0 million and $2.0 million for the three and nine months ended July 31, 2025, respectively, and a mark-to-market net loss of $0.9 million and $5.1 million for the three and nine months ended July 31, 2024, respectively, related to natural gas purchase contracts as a result of net settling certain natural gas purchases under previous normal purchase normal sale contract designations, which resulted in a change to mark-to-market accounting. These gains and losses are classified as Generation cost of sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) The Company recorded a non-cash impairment expense of $64.5 million for the three and nine months ended July 31, 2025 related to the Company's prior investments in solid oxide technology, related goodwill and in-process research and development intangible assets, property, plant and equipment and solid oxide inventory.

Earnings before interest, taxes, depreciation and amortization EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders 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, Adjusted EBITDA, Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders 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, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, which are considered either non-cash or non-recurring. Adjusted net loss attributable to common stockholders and Adjusted net loss per share attributable to common stockholders differ from the most comparable GAAP measures, Net loss attributable to common stockholders and Net loss per share attributable to common stockholders, primarily because they do not include stock-based compensation, impairment and restructuring expenses, non-cash (gain) loss on derivative instruments and other unusual items, 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 - 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 th financial statements prepared in accordance with GAAP. On the following slides, we calculate EBITDA and Adjusted EBITDA and reconcile these figures to the GAAP financial statement measure Net loss; we calculate Adjusted net loss attributable to common stockholders and reconcile that figure to the GAAP financial statement measure Net loss attributable to common stockholders; and we calculate Adjusted net loss per share attributable to common stockholders. |
