Segments and Geographic Information
We operate in two reportable segments consisting of the Probe Cards Segment and the Systems Segment.

Our chief operating decision maker (“CODM”) is our President and Chief Executive Officer, who assesses the reportable segments' performance by using each reportable segment's net contribution to make decisions about allocating resources and assessing performance for the entire company. The CODM uses net contribution for each reportable segment predominantly in the annual budget and forecasting process, as well as consideration of budget-to-actual variances on a quarterly basis when making decisions for assessment of our performance and results of operations. Certain components of net contribution are utilized to determine executive compensation along with other measures.

The following table provides net contribution by reportable segment and includes a reconciliation to income before income taxes (dollars in thousands):

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.
