Subsequent Events	Note 19. Subsequent Events On June 4, 2025, the Board approved a global restructuring plan to further reduce operating costs, realign resources toward advancing the Company’s core carbonate technologies, and protect the Company’s competitive position amid slower-than-expected market investments in clean energy. This plan includes: (i) a workforce reduction of 122 employees, or approximately 22% of our workforce across the U.S., Canada and Germany (which reduction was implemented on June 5, 2025), (ii) a significant reduction of discretionary overhead spending, (iii) recalibration of the Torrington manufacturing facility production schedule to align with contracted demand, rather than forecasted demand, which, without continued growth in our closed order book, would result in a decrease in our annualized production rate, (iv) the deferral of certain compensation and benefit obligations, (v) the cessation of the majority of development efforts with respect to our solid oxide technology, and (vi) other targeted cost-saving measures. These steps reflect our commitment to strategic discipline and focus, with the goal of ensuring we continue to advance our most commercially viable technology while preserving the long-term optionality of our broader platform innovations. The actions under this restructuring plan are expected to be substantially completed by the end of fiscal year 2025. In connection with this restructuring plan and workforce reduction, the Company estimates it will incur aggregate restructuring-related costs and charges of approximately $3.5 million to $4.5 million in cash costs related to severance payments and other employee termination benefits. The majority of these charges are expected to be recorded in the third quarter of fiscal year 2025. In conjunction with this restructuring plan, the Company is evaluating certain assets for impairment including Goodwill and in-process research and development (“IPR&D”) intangible assets, with a net book value of $13.8 million as of April 30, 2025 related to the Company’s prior investments in solid oxide technology, related property, plant and equipment located in Calgary, Canada with a net book value of $38.8 million as of April 30, 2025 and solid oxide inventory with a net book value of $8.8 million as of April 30, 2025. As of June 6, 2025, the Company believes the likelihood of an impairment charge in the third quarter of fiscal year 2025 is more likely than not, but is unable to estimate the recovery value of such assets, if any, at this time.
