The company operates globally with a portfolio including analytics software (Exensio), connectivity solutions (Cimetrix, secureWISE), and hardware systems (DirectScan, Characterization Vehicle).

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Total revenue increased 22% year-over-year. Volume-based revenue surged 70% driven by Gainshare, secureWISE data usage, and Cimetrix runtime licenses. Platform revenue grew 15%, aided by fixed fees from CV systems and secureWISE, offset by declines in perpetual licenses and DirectScan systems.
• Profitability Decline: Despite revenue growth, the company reported a net loss of $0.6 million in 2025 compared to net income of $4.1 million in 2024. This was primarily due to increased operating expenses (personnel, subcontractors, legal fees related to arbitration), interest expense from new debt, and higher income tax expenses.
• Acquisition Impact: The acquisition of SecureWise in March 2025 resulted in significant goodwill ($81.7 million) and intangible assets ($46.2 million), leading to a 300% increase in amortization of acquired intangible assets.
• Debt Financing: The company entered a Credit Agreement in March 2025, securing a $45 million revolving facility and a $25 million term loan to finance the SecureWise acquisition. This introduced $3.96 million in interest expense for the year.

Guidance, Outlook, Risks, and Unusual Items

• Outlook: Management expects continued investment in R&D and headcount to support product development. The company anticipates that existing cash resources and funds from operations will satisfy requirements for at least the next 12 months.
• Legal Contingency: The company won an arbitration award against SMIC New Technology Research & Development (Shanghai) Corporation in November 2025. However, no payments have been received, and SMIC filed an application to set the award aside in February 2026. No amounts have been recognized in the financial statements.
• Customer Concentration: Three customers accounted for 53% of total revenues in 2025. Two customers accounted for 64% of gross accounts receivable as of December 31, 2025.
• Regulatory Risks: The company faces risks from U.S. export controls (BIS Entity List), trade tariffs, and evolving AI regulations globally. Changes in these regulations could restrict sales to certain customers, particularly in China.
• Tax Legislation: The "One Big Beautiful Bill Act" (OBBBA) enacted in July 2025 provided a favorable cash tax benefit of approximately $1.3 million and reduced the effective tax rate by 40% in 2025.

Investor Verification Checklist

• SMIC Arbitration Recovery: Verify the status of the enforcement of the arbitration award against SMIC and the likelihood of collecting the unpaid fees.
• SecureWise Integration: Assess the progress of integrating SecureWise operations and whether the anticipated revenue synergies are materializing.
• Customer Concentration: Monitor the stability of the top three customers, which represent over half of the company's revenue.
• Debt Covenants: Confirm continued compliance with the Credit Agreement covenants, specifically the consolidated total net leverage ratio (max 3.00:1.00) and fixed charge coverage ratio (min 1.25:1.00).
• Export Control Impact: Evaluate the potential impact of evolving U.S. export restrictions on revenue from Chinese semiconductor manufacturers.
