In the fiscal quarter ended June 30, 2026 (the “June 2026 quarter”), revenue increased 17.5% compared to the fiscal quarter ended March 31, 2026 (the “March 2026 quarter”), primarily due to higher sales of inspection and metrology systems supporting advanced packaging and advanced node semiconductor…
Gross profit as a percentage of revenue for the June 2026 quarter increased by 330 basis points compared to the March 2026 quarter. This margin increase was primarily driven by a favorable shift in sales mix as product sales move toward high-margin inspection and metrology product lines.
Operating expenses for the June 2026 quarter increased by 6.1% compared to the March 2026 quarter. This increase was driven by higher compensation-related costs, increased headcount, and engineering spend related to product development activities.

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
