[1] The significant expense categories and amounts align with the segment-level information that is regularly provided to the chief operating decision maker. Intersegment expenses are included within the amounts shown.
[2] Profit or loss from segments below the quantitative thresholds are attributable to four operating segments that include the sales and distribution of semiconductors, and the newly acquired Wecan and Miraex. None of those segments has ever met any of the quantitative thresholds for determining reportable segments. It also includes the holding company SEALSQ Corp, that does not meet the definitions of a reportable segment.
