(10) Segment Information
The Company’s reportable segments are reported in a manner consistent with the way management evaluates the businesses. The results of operations are regularly reviewed by the Company's chief operating decision maker ("CODM"), the Chief Executive Officer. The Company identifies its reportable business segments based on differences in products and services. The accounting policies of the business segments are the same as those described in the summary of significant accounting policies. In order to evaluate each reportable segment's performance, the CODM uses income from operations as a measure of profit and loss. The CODM compares operational performance against management expectations when making decisions regarding allocation of operating and capital resources to each segment.
In 2026, the Company has five reportable segments which include: Theranostics Products, Cobalt Products, Calibration & Reference Products, Medical Device Products, and Fluorine Products.
