Reporting Period: Quarter ended September 30, 2025 (Q3 2025)

Key Financial Metrics

Note: Net Loss attributable to common shareholders includes significant non-cash charges related to the remeasurement of preferred stock and changes in fair value of warrants and derivatives.

Material Changes vs. Prior Period

• Revenue Surge: Revenue increased 3,473% year-over-year in Q3 2025 and 573% for the nine-month period, driven by higher product sales volume and pricing as the company scales commercial deliveries.
• Loss Expansion: Net loss widened significantly due to non-cash fair value adjustments on warrants and derivatives, as well as the remeasurement of Series B Preferred Stock. Operating losses increased due to higher costs of goods sold associated with scaling production.
• Debt Restructuring: The company fully funded its $210.5 million Delayed Draw Term Loan (DDTL) with Cerberus. It also issued $250 million in 2025 Convertible Notes and repaid the 2021 Convertible Notes, resulting in a $52.7 million loss on debt extinguishment for the nine months ended September 30, 2025.
• DOE Loan Facility: The company drew down the full $90.9 million commitment for Tranche 1 of the DOE Loan Facility to fund the first automated manufacturing line.

Guidance, Outlook, and Risks

• Going Concern: Management has raised substantial doubt about the company's ability to continue as a going concern without additional capital, citing significant accumulated deficits and negative operating cash flows. However, recent financing (Cerberus DDTL, DOE Loan, Convertible Notes, and Equity Offering) is intended to provide a path to sustainability.
• Operational Milestones: The company satisfied its final performance milestones (Sales Milestone 4) under the Cerberus Credit Agreement in October 2025, preventing further equity dilution to the lender.
• Capital Expenditures: Significant investments are ongoing for manufacturing expansion, including new lease agreements for office and manufacturing space in Pennsylvania totaling approximately $58.8 million in minimum lease payments.
• Risks: Key risks include the ability to convert backlog to revenue, supply chain disruptions, compliance with financial covenants (Minimum Liquidity is currently the only active covenant), and the impact of changing energy policies (e.g., the "One Big Beautiful Bill Act").

Investor Verification Checklist

• Cash Burn Rate: Verify the sustainability of operations given the $160.9 million negative operating cash flow for the nine months ended September 30, 2025, against the $58.7 million unrestricted cash balance.
• Debt Covenants: Confirm ongoing compliance with the Minimum Liquidity covenant and monitor the deferred Revenue and EBITDA covenants effective March 31, 2027.
• Revenue Quality: Assess customer concentration; one customer accounted for 82.1% of Q3 2025 revenue, and three customers accounted for 73.0% of the nine-month revenue.
• Non-Cash Charges: Distinguish between operational losses and non-cash fair value adjustments (warrants, derivatives, preferred stock) which heavily impacted the reported net loss.
• DOE Loan Tranches: Monitor the achievement of conditions required to draw down Tranches 2, 3, and 4 of the DOE Loan Facility, which are critical for funding future production lines.
