Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Decline: Total revenue decreased 40% quarter-over-quarter and 8% year-over-year (YTD). The decline is attributed to fewer equipment deliveries and a shift in revenue recognition timing.
• Cost Reduction: Cost of revenue decreased significantly (61% QoQ, 41% YTD) due to fewer deliveries and lower inventory write-downs. Operating expenses also dropped substantially, with R&D down 62% QoQ and Sales & Marketing down 86% QoQ, driven by workforce reductions and furloughs implemented in May 2025.
• Financing Activity: The company entered into a Sale-Leaseback agreement with UOP (Honeywell affiliate) in July 2025, creating a $10.5 million financing obligation. Additionally, the company raised capital through a Standby Equity Purchase Agreement (SEPA), selling shares for $3.6 million in Q3 and completing the full $25 million offering in October 2025.
• Inventory: Inventory levels decreased from $5.6 million to $4.7 million, with a net realizable value adjustment of $15.5 million remaining on the balance sheet.

Outlook, Risks, and Contingencies

• Going Concern Warning: Management has expressed substantial doubt about the company's ability to continue as a going concern for 12 months from the filing date due to recurring losses and insufficient cash to fund operations without additional financing.
• Capital Raising: The company is actively pursuing additional debt or equity financing. Subsequent to the quarter end, the company entered into a $40 million Promissory Note (with $15 million repaid as of the report date) and completed the $25 million SEPA offering.
• NYSE Listing Compliance: The company received notice from the NYSE in March 2025 regarding non-compliance with minimum market capitalization and stockholders' equity standards. A cure plan was submitted, but failure to comply could result in delisting.
• Cybersecurity Incident: On November 1, 2025, the company experienced a cybersecurity incident involving unauthorized access, resulting in system unavailability. An investigation is ongoing, and the material impact is currently undetermined.
• Regulatory Changes: The company is evaluating the impact of the "One Big Beautiful Bill Act" (OBBB) signed in July 2025, which modifies tax credits under the Inflation Reduction Act (IRA).

Investor Verification Checklist

• Liquidity Runway: Verify the sufficiency of the $3.5 million unrestricted cash balance against the $36.4 million YTD operating cash burn rate.
• Financing Terms: Review the specific terms of the $40 million Promissory Note and the $25 million SEPA, including dilution effects and repayment schedules.
• NYSE Status: Monitor the status of the NYSE compliance plan and the risk of potential delisting.
• Cybersecurity Impact: Assess the final outcome of the November 2025 cybersecurity incident regarding data loss, operational downtime, and remediation costs.
• Related Party Transactions: Scrutinize the $2.4 million in related party revenue (primarily Honeywell/UOP) and the $10.5 million sale-leaseback financing obligation.
• Inventory Valuation: Confirm the validity of the $15.5 million inventory write-down and the remaining net realizable value of inventory.
