Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 19.7% year-over-year, driven by a 25.1% increase in product revenue (systems and consumables) and a 9.0% increase in service revenue.
• Gross Margin Turnaround: The company achieved a positive gross margin of 3.1% in 2025, improving from a negative margin of (0.4)% in 2024. This marks the first full year of positive gross margins in company history.
• Debt Financing: In August 2025, the company entered a Loan and Security Agreement with Trinity Capital Inc., drawing the initial $20.0 million tranche of a $45.0 million facility. This resulted in $1.1 million of interest expense in 2025 compared to negligible interest in 2024.
• Operating Expenses: Research and Development expenses decreased 6.8% and Sales and Marketing expenses decreased 8.9%, primarily due to reduced headcount and lower consulting costs.
• Strategic Partnership: In February 2025, the company signed a Distribution and Collaboration Agreement with MilliporeSigma (Merck KGaA) to distribute Growth Direct systems globally.

Guidance, Outlook, and Risks

• Liquidity: Management believes existing cash, cash equivalents, and investments ($38.3 million) are sufficient to fund operations for at least 12 months. The company aims to achieve positive cash flow without additional financing but notes this is not guaranteed.
• Outlook: Growth is expected to be driven by new customer adoption, expansion within existing customer sites (land-and-expand strategy), and the commercialization of the rapid sterility application launched in 2024.
• Key Risks:
  • Profitability: The company has incurred significant losses since inception with an accumulated deficit of $522.4 million. Future profitability depends on revenue growth and margin expansion.
  • Customer Concentration: Three customers accounted for 29.7% of total revenue in 2024, and significant revenue is derived from a small number of large system orders.
  • Supply Chain: Reliance on single-source suppliers for critical components (e.g., cameras) poses a risk of production delays.
  • Regulatory: While the platform is not directly FDA-regulated, customer adoption depends on regulatory validation and compliance with data integrity standards.

Investor Verification Checklist

• Debt Covenants: Verify the specific commercial and operational milestones required to access the remaining $25.0 million of the Trinity Capital loan facility.
• Margin Sustainability: Confirm whether the 3.1% gross margin is sustainable given the mix of high-cost system sales versus recurring consumable revenue.
• MilliporeSigma Commitments: Review the specific minimum purchase commitments MilliporeSigma has made for the first two years of the distribution agreement.
• Inventory Valuation: Assess the $1.2 million inventory reserve for excess and obsolete items and the risk of further write-downs if demand slows.
• Section 382 Limitations: Understand the limitations on utilizing Net Operating Losses (NOLs) due to prior ownership changes, which may restrict future tax benefits even if the company becomes profitable.
