Segment Reporting and Geographic Information:

The Company is organized and operates as one operating and reportable segment; the design, development, manufacture and support of high-performance control metrology, defect inspection, lithography and data analysis systems used by microelectronics device manufacturers. This determination is based on the management approach which designates internal information regularly available to the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of determination of the Company’s reportable segments. The Company’s CODM, the Chief

Executive Officer, reviews financial information presented on a consolidated basis for the purpose of making operating decisions and assessing financial performance.

The CODM uses net income as the measure of profit or loss to allocate resources and assess performance. The CODM regularly reviews net income as reported on the Company’s consolidated statements of operations. Financial forecasts and budget to actual results used by the CODM to assess performance and allocate resources, as well as those used for strategic decisions related to headcount and capital expenditures are also reviewed on a consolidated basis. The CODM considers the impact of the significant segment expenses in the table below on net income when deciding whether to reinvest profits, propose share repurchase, or pursue strategic mergers and acquisitions.

The measure of segment assets is reported on the balance sheet as total assets. The CODM does not review segment assets at a level other than that presented in the Company’s consolidated balance sheets.

The table below presents the Company’s consolidated operating results including significant segment expenses:

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
