Segments | Note 15. Segments We are engaged in the development, design, production, construction, operation and servicing of high temperature fuel cells for clean electric power generation. Critical to the success of our business is, among other things, our research and development efforts, both through customer-sponsored projects and Company-sponsored projects. The research and development activities are viewed as another product line that contributes to the development, design, production and sale of fuel cell products, however, it is not considered a separate operating segment. Our Chief Operating Decision Maker (“CODM”) is our President and Chief Executive Officer. The CODM does not review and assess financial information at a discrete enough level to be able to assess performance of research and development activities as if they operated as a standalone business segment. The CODM is provided with and reviews on a regular basis the Company’s consolidated Net loss, which is our reported measure of segment profit and loss, when making decisions about allocating resources and assessing the performance of the Company. Therefore, the Company has identified one reportable segment: fuel cell power plant production and research. Significant segment expenses that are provided to the CODM on a regular basis and are included within consolidated Net loss, which is our reported measure of segment profit and loss are: •Cost of product revenues, •Cost of service agreements revenues, •Cost of generation revenues, •Cost of Advanced Technologies contract revenues, •Administrative and selling expenses, and •Research and development expenses. ​ Other segment items are represented by Interest expense, Interest income, Other income (expense), net, Provision for income taxes and unusual items from time to time, such as Restructuring expense and Impairment expense. The CODM is not regularly provided a measure of segment assets. Please refer to the Consolidated Statements of Operations and Comprehensive Loss for the three and six months ended April 30, 2026 and 2025 for significant segment expenses and other segment items.
