Principles of Consolidation

​

The unaudited consolidated financial statements reflect our accounts and operations and those of our subsidiaries in which we have a controlling financial interest. We use a qualitative approach in assessing the consolidation requirement for each of our variable interest entities ("VIEs"), which are tax equity partnerships further described in Note 3. “Tax Equity Financings.” This approach focuses on determining whether we have the power to direct those activities of the tax equity partnerships that most significantly affect their economic performance and whether we have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the tax equity partnerships. For all periods presented, we have determined that we are the primary beneficiary in all of our tax equity partnerships. We evaluate our tax equity partnerships on an ongoing basis to ensure that we continue to be the primary beneficiary.

Liquidity

Our principal sources of cash have been proceeds from the sale of our products and projects, electricity generation revenues, research and development and service agreements with third parties, sales of our common stock through public equity offerings, and proceeds from debt, project financing and tax monetization transactions. We have utilized this cash to accelerate the commercialization of our solid oxide platforms, develop new capabilities to separate and capture carbon, develop and construct project assets, invest in capital improvements and expansion of our operations, perform research and development, pay down existing outstanding indebtedness, and meet our other cash and liquidity needs.

​

As of April 30, 2026, unrestricted cash and cash equivalents totaled $373.2 million compared to $278.1 million as of October 31, 2025. There were no outstanding U.S. Treasury Securities as of April 30, 2026 or October 31, 2025, as all U.S. Treasury Securities that were outstanding during the three and six month periods ended April 30, 2025 matured prior to October 31, 2025.

​

During the first quarter of fiscal year 2026, the Company received the third and final annual funding from East West Bancorp, Inc. (“East West Bank”) under the tax equity financing transaction between the Company and East West Bank and, as a result, the Company received a $4.0 million contribution which is recorded as noncontrolling interest on the Consolidated Balance Sheets.

​

On April 10, 2024, the Company entered into Amendment No. 1 to the Open Market Sale Agreement, dated July 12, 2022 (as amended, the “Sales Agreement”), with Jefferies LLC, B. Riley Securities, Inc., Barclays Capital Inc., BMO Capital Markets Corp., BofA Securities, Inc., Canaccord Genuity LLC, Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Loop Capital Markets LLC (each, an “Agent” and together, the “Agents”), with respect to an at the market offering program under which the Company could, from time to time, offer and sell shares of its common stock having an aggregate offering price of up to $300.0 million (exclusive of any amounts previously sold under the Sales Agreement prior to its amendment). On December 27, 2024, the Company entered into Amendment No. 2 to the Sales Agreement, which removed certain representations and warranties relating to the Company’s status as a well-known seasoned issuer. Following the sale of substantially all of the $300.0 million of shares previously available under the Sales Agreement, on December 30, 2025, the Company entered into Amendment No. 3 to the Sales Agreement, which removed J.P. Morgan Securities LLC as an Agent and increased the amount of shares that may be sold by the Company under the Sales Agreement to $200.0 million (exclusive of any amounts previously sold under the Sales Agreement prior to the date of Amendment No. 3). During the three months ended April 30, 2026, approximately 10.9 million shares of the Company’s common stock were sold under the Sales Agreement at an average sale price of $9.45 per share, resulting in gross proceeds of approximately $102.6 million before deducting sales commissions and fees, and net proceeds to the Company of approximately $100.4 million after deducting sales commissions totaling approximately $2.1 million and fees totaling approximately $0.1 million. During the six months ended April 30, 2026, approximately 17.2 million shares of the Company’s common stock were sold under the Sales Agreement at an average sale price of $9.22 per share, resulting in gross proceeds of approximately $158.9 million before deducting sales commissions and fees, and net proceeds to the Company of approximately $155.3 million after deducting sales commissions totaling approximately $3.2 million and fees totaling approximately $0.4 million. See Note 12. “Stockholders’ Equity” for additional information regarding the Sales Agreement and Note 20. “Subsequent Events” for additional information regarding sales made subsequent to April 30, 2026 under the Sales Agreement.

​

We believe that our unrestricted cash and cash equivalents, expected receipts from our contracted backlog and release of short-term restricted cash less expected disbursements over the next twelve months will be sufficient to allow the Company to meet its obligations for at least one year from the date of issuance of these financial statements.

​

To date, we have not achieved profitable operations or sustained positive cash flow from operations. The Company’s future liquidity, for the remainder of fiscal year 2026 and in the long-term, will depend on its ability to (i) timely complete current projects in process within budget, (ii) increase cash flows from its generation portfolio, including by meeting conditions required to timely commence operation of new projects, operating its generation portfolio in compliance with minimum performance guarantees and operating its generation portfolio in accordance with revenue expectations, (iii) obtain financing for project construction and manufacturing expansion, (iv) obtain permanent financing for its projects once constructed, (v) increase order and contract volumes, which would lead to additional product sales, service agreements and generation revenues, (vi) obtain funding for and receive payment for research and development under current and future Advanced Technologies contracts, (vii) successfully advance the commercialization of its solid oxide and carbon capture platforms through partnerships with third parties, (viii) implement capacity expansion for its carbonate products, (ix) seek partnerships for solid oxide product commercialization and manufacturing, (x) implement the product cost reductions necessary to achieve profitable operations, (xi) manage working capital and the Company’s unrestricted cash balance and (xii) access the capital markets to raise funds through the sale of debt and equity securities, convertible notes, and other equity-linked instruments.

​

We are continually assessing different means by which to accelerate the Company’s growth, enter new markets, commercialize new products, and enable capacity expansion. Therefore, from time to time, the Company may consider and enter into agreements for one or more of the following: negotiated financial transactions, minority investments, collaborative ventures, technology sharing, transfer or other technology license arrangements, joint ventures, partnerships, acquisitions or other business transactions for the purpose(s) of geographic or manufacturing expansion and/or new product or technology development and commercialization, including hydrogen production through our carbonate and solid oxide platforms and storage and carbon capture, sequestration and utilization technologies.

​

Our business model requires substantial outside financing arrangements and satisfaction of the conditions of such arrangements to construct and deploy our projects to facilitate the growth of our business. The Company has invested capital raised from sales of its common stock to build out its project portfolio. The Company has also utilized and expects to continue to utilize a combination of long-term debt and tax equity financing (e.g., sale-leaseback transactions, partnership flip transactions and the monetization and/or transfer of eligible investment and production tax credits) to finance its project asset portfolio as these projects commence commercial operations. The Company may also seek to undertake private placements of debt securities to finance its project asset portfolio. The Company is also pursuing financing to support its commercial efforts, which include deployment of modules to the repowering opportunities in the South Korean market including the GGE (as defined elsewhere herein) project. The proceeds of any such financing, if obtained, may allow the Company to reinvest capital back into the business and to fund other projects. We also expect to seek additional financing in both the debt and equity markets in the future. If financing is not available to us on acceptable terms if and when needed, or on terms acceptable to us or our lenders, if we do not satisfy the conditions of our financing arrangements, if we spend more than the financing approved for projects, if project costs exceed an amount that the Company can finance, or if we do not generate sufficient revenues or obtain capital sufficient for our corporate needs, we may be required to further reduce or slow planned spending, further reduce staffing, sell assets, seek alternative financing and take other measures, any of which could have a material adverse effect on our financial condition and operations.
