- Expenses: Research and development declined 10% to $50.7 million; selling, general and administrative expense increased 37% to $62.2 million. SG&A growth chiefly reflected personnel and stock-based compensation costs.
- Cash flow: Operating cash flow was $14.6 million, down from $32.3 million in 2022. Capital expenditures and prepayments for property and equipment were $11.3 million. Cash and cash equivalents were $99.0 million at year-end.

- Other metrics: One customer generated 35% of 2023 revenue; two customers represented 50% of gross receivables. International revenue was 44%, down from 50% in 2022. Stock-based compensation expense was $21.5 million.
Changes versus 2022
- Analytics growth, led by DFI and CV systems (including sales-type leases) and Exensio software licenses, more than offset lower Integrated Yield Ramp revenue. Cimetrix runtime-license revenue declined.
- Integrated Yield Ramp revenue fell primarily because of fewer hours on fixed-fee engagements and lower Gainshare associated with reduced customer wafer shipments at non-leading-edge nodes.
- Net income improved by $6.5 million, supported by higher revenue, interest income and lower R&D and income tax expense. Higher SG&A and cost of revenue partly offset those gains.
- Operating cash flow decreased $17.7 million, largely reflecting payments to vendors and employees, including bonuses. The company completed a $1.8 million net-cash acquisition of Lantern Machinery Analytics, expanding into battery manufacturing analytics.
Outlook, risks and unusual items
- No numerical revenue or earnings guidance is provided. Management believes current cash resources and anticipated operating funds should cover operations, capital expenditures and obligations for at least the next 12 months. It expects R&D and SG&A to vary with project timing and business needs.
- Management cites cautious customer spending, longer purchasing cycles, elevated semiconductor inventories and lower fab utilization. It expects wafer-volume-dependent Gainshare revenue to remain exposed to customer production levels and other factors outside the company’s control.
- Customer concentration is material, and the company identifies a risk that reduced business, payment delays, consolidation or pricing pressure from a major customer could adversely affect results. Two customers accounted for half of gross receivables at year-end; unbilled receivables included in accounts receivable were $16.4 million.
- PDF Solutions is pursuing arbitration against SMIC over unpaid contractual fees; SMIC denies liability, and a decision was expected in 2024. Arbitration-related expense was $2.6 million in 2023. Separately, a provider of enabling software stopped maintenance and support in November 2023; the company took legal action and says the longer-term business impact is unknown.
- Other disclosed risks include evolving U.S.-China export restrictions and geopolitical tensions, reliance on specialized suppliers, cybersecurity and customer-data protection, and the uncertain commercial returns from DFI investment and expansion into battery analytics.
- The independent auditor issued unqualified opinions on the financial statements and internal control over financial reporting. Revenue recognition was identified as a critical audit matter because of judgment in contract allocations, fixed-fee completion estimates and Gainshare accruals.
