Overview
The earnings call reveals ongoing financial challenges, including significant net losses and limited liquidity, despite cost reductions. The company's dependence on future revenues from the Energy Base platform, with no substantial revenue expected until 2027, raises concerns. Leadership changes and competitive pressures further add to uncertainties. The Q&A session highlighted management's vague responses on key projects and liquidity plans, which could undermine investor confidence. These factors suggest a negative sentiment, likely leading to a stock price decline of -2% to -8% over the next two weeks.
Key Financial Performance
Revenue for the full year 2025 $1.6 million, down from $6.3 million in 2024. This reflects the deliberate transition away from legacy product lines, the Energy Warehouse and Energy Center, as the company refocuses on the Energy Base.
Gross loss for the year 2025 $27.7 million, an improvement of 39% compared to a loss of $45.4 million in 2024. This improvement is attributed to the organizational reset undertaken by the company.
Total operating expenses for 2025 $29.7 million, down 33% year-over-year from $44.4 million in 2024. This reduction reflects the organizational reset and cost-cutting measures.
Net loss for the full year 2025 $63.4 million compared to $86.2 million in 2024, an improvement of 26%. This improvement is due to significant cost reduction efforts.
Adjusted EBITDA for 2025 Improved 38% to a loss of $44.3 million from a loss of $71.3 million in 2024. This reflects significant cost reduction work across the business, with reductions being structural and not temporary.

Key Q&A
Q:What is the outlook for the ramp-up in revenues associated with the 3 key projects starting in 2027? Could there be any revenue in 2026?
A:The focus for 2026 will be on commercializing the new product, Energy Base, to deliver for Tier 1 customers in 2027 and 2028. These customers represent revenues and megawatts installed that are multiples higher than the company's cumulative achievements since 2021. Most revenues are expected in 2027 and 2028, with a pragmatic approach in 2026 to ensure high-quality product delivery.
Q:What is the update on the ownership structure of the Salt River project and its revenue timeline?
A:The Salt River project is still in the planning phase regarding its financial and structural ownership. The agreement is a 10-year PPA, with recurring revenues expected to start in 2028. The company is exploring options to make it more of an equipment sale rather than just a PPA, but no concrete updates are available yet.
Q:What is the potential for follow-on deployments associated with the Salt River project?
A:There is potential for a much larger follow-on project with SRP. The company aims to have the pilot project operational and provide good data by mid-2028. Execution of the pilot project with high-quality technology and product is critical to setting up for future opportunities. The timeline for follow-on opportunities depends on the successful execution of the pilot.
Q:What are the plans for liquidity, including repayment of promissory notes, use of the ATM, or additional capital raises?
A:The financial runway has significantly improved since November, with a healthier balance sheet due to recent fundraises. While further capital is needed for plans in 2027 and beyond, there is no immediate rush to raise capital. The company plans to be thoughtful and strategic about future capital access, with no immediate plans to use the ATM.
Q:Review of Unclear Management Responses
A:Management avoided providing a direct answer regarding the ownership structure of the Salt River project, stating that it is still in the planning phase and offering no concrete updates. Additionally, while they mentioned exploring options to make the project more of an equipment sale, no specific details or decisions were shared.
