Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Revenue increased 35.3% year-over-year (YoY) for the quarter and 22.1% YoY for the six-month period. Growth was driven by higher sales of inspection and metrology systems for advanced packaging and node applications.
• Margin Expansion: Gross margin improved to 53.4% in Q2 2026 from 48.2% in Q2 2025, attributed to a favorable sales mix shift toward high-margin products and lower restructuring expenses compared to the prior year.
• Operating Expenses: Total operating expenses rose to $119.7 million (Q2 2026) from $89.9 million (Q2 2025). Increases were driven by higher compensation costs, increased headcount, and significant amortization of intangible assets ($19.7 million) related to the Semilab USA acquisition.
• Capital Structure: The company issued $1.5 billion in 0.00% Convertible Senior Notes due 2031 in May 2026. Proceeds were used to fund capped call transactions ($88.9 million), repurchase 805,000 shares of common stock ($204.9 million), and for general corporate purposes.

Outlook, Risks, and Unusual Items

• Acquisitions:
  • Semilab USA: Completed in November 2025. Contributed $20.7 million in revenue and a $4.5 million operating loss in Q2 2026. Significant intangible asset amortization is impacting operating income.
  • Rigaku Transaction: Entered into an agreement in April 2026 to acquire 27% of Rigaku Holdings Corporation for approximately $710 million. Expected to close in H2 2026.
• Debt and Liquidity: The company terminated a $500 million bridge loan commitment in May 2026 following the successful Notes issuance. Total cash, cash equivalents, and marketable securities stood at $1.88 billion as of June 30, 2026.
• Risks: Key risks include the ability to fund cash payments upon conversion of the 2031 Notes, potential dilution to shareholders, and counterparty risk associated with the Capped Call Transactions. The company also faces standard semiconductor industry risks regarding customer capital spending and supply chain constraints.
• Restructuring: Restructuring and other expenses were $3.8 million for the quarter, primarily related to employee severance and business transformation projects.

Investor Verification Checklist

• Convertible Note Terms: Verify the conversion price ($381.80) and the conditions under which the 2031 Notes become convertible or redeemable, as this impacts future dilution and liquidity.
• Amortization Impact: Assess the duration and magnitude of amortization expenses from the Semilab USA acquisition ($210 million in intangibles) to understand its drag on future operating margins.
• Rigaku Closing: Monitor the closing timeline and integration plan for the Rigaku investment, including the use of remaining cash reserves or additional financing.
• Customer Concentration: Note that five customers accounted for approximately 64.3% of accounts receivable, indicating high concentration risk.
• Fiscal Year Change: Confirm how the shift to a calendar fiscal year-end affects future quarterly comparability and reporting cycles.
