Risks

• Ability to leverage resources to improve position in core markets.
• Ability to weather difficult economic environments.
• Ability to open new market opportunities and target high-margin markets.
• Strength or weakness of the back-end and/or front-end semiconductor market segments.
• Fluctuations in customer capital spending.
• Ability to effectively manage its supply chain and adequately source components from suppliers to meet customer demand.
• Effects of political, economic, legal, and regulatory changes, including tariffs and trade disputes, or conflicts on global operations.
• Ability to adequately protect intellectual property rights and maintain data security.
• Effects of natural disasters or public health emergencies on the global economy and on customers, suppliers, employees, and business.

Future Outlook

The company anticipates the third fiscal quarter of 2025 to be a low watermark for the year in terms of revenue. However, it expects an acceleration in AI packaging spend in the fourth quarter, which should return total fourth quarter revenue to levels consistent with the first and second quarters of 2025, with continued momentum projected into 2026. The acquisition of Semilab product lines is expected to add over $130 million in annual revenue and be immediately accretive to earnings per share, further increasing the breadth and depth of the company's portfolio.

Management Comments

• We continue to increase our value to customers through innovative development across our product platforms as evidenced by an expected near doubling of revenue in 2025 in advanced nodes markets, expanded positions in Dragonfly's 3Di interconnect metrology, and validated sensitivity and scan time performance in our next generation inspection Dragonfly system.
• The new material characterization capabilities from the pending Semilab acquisition further increases the breadth and depth of our portfolio.
• While third quarter revenue will likely represent a low watermark for the year, we expect an acceleration in AI packaging spend in the fourth quarter which should return total fourth quarter revenue to a level consistent with what we reported in the first and second quarters of this year with continued momentum into 2026.
