Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 2% to a record $20.9 million, driven by a 91% surge in Integrated Coating Systems and a 54% increase in Medical market sales.
• Margin Expansion: Gross margin improved to 51% from 48%, attributed to a favorable product mix (higher average selling price systems) and a higher concentration of domestic shipments which reduce distributor expenses.
• Market Shifts:
  • Medical: Sales rose 54% ($1.75M increase) due to demand for drug-eluting balloon and stent coating systems.
  • Alternative Energy: Sales declined 19% ($1.86M decrease) primarily due to reduced demand for electrolysis-related applications following government policy changes, partially offset by solar shipments.
  • Geography: US/Canada sales increased 12%, while international sales (33% of total) declined due to regional demand variability.
• Operating Expenses: Total operating expenses remained flat ($8.74M). Research and Development (R&D) decreased 6% due to personnel changes and reduced material costs. General and Administrative (G&A) expenses increased 14% due to higher salaries and stock-based compensation.
• Tax Impact: Income tax expense increased to $461k (from $261k) due to higher pre-tax income, though the effective rate was mitigated by the "One Big Beautiful Bill Act" (OBBBA), which allowed for the retroactive expensing of R&D costs previously capitalized.

Guidance, Outlook, Risks, and Contingencies

• Outlook: Management expects continued growth driven by the transition to higher-value, production-scale systems. The company anticipates increased marketing and sales expenses in Fiscal 2027 to support new business opportunities.
• Key Risks:
  • Customer Concentration: One customer accounted for 28% of net sales in Fiscal 2026 (up from 11% in 2025). Three customers accounted for 61% of accounts receivable.
  • Geopolitical Instability: The filing highlights risks associated with the ongoing military conflict between the US and Iran, including potential supply chain disruptions, energy price spikes, and increased cybersecurity threats.
  • Trade Policy: Exposure to US trade policy changes, tariffs, and trade restrictions that could increase costs or reduce demand.
  • Single Facility: All manufacturing and assembly occur at one facility in Milton, NY, creating operational risk in the event of disruption.
• Contingencies: No material legal proceedings or off-balance sheet arrangements were reported. The company resolved a California sales tax accrual in the prior year, with no remaining uncertain tax positions as of February 28, 2026.

Investor Verification Checklist

• Customer Concentration: Verify the identity and financial stability of the single customer representing 28% of revenue to assess dependency risk.
• Backlog Conversion: Monitor the conversion rate of the $9.12 million backlog into recognized revenue in upcoming quarters.
• Alternative Energy Exposure: Assess the long-term impact of reduced government incentives on the Alternative Energy segment, which saw a 19% decline.
• Geopolitical Impact: Evaluate the company's specific exposure to supply chain disruptions related to the US-Iran conflict and potential tariff increases.
• Stock Repurchase Plan: Note that the $2 million stock repurchase plan terminated in January 2026; verify if a new plan will be authorized.
