For each of the business segments, the chief operating decision maker (CODM) reviews internal management reports on at least a quarterly basis. The operations in each of the Group’s reportable segments are as follows; Segment 1 Upstream (including Refinery, Aromatics and Olefins) Segment 2 Intermediates (including EO-Based Performance, Phenol and others) Segment 3 Polymers and Chemicals Segment 4 Bio and Circularity Segment 5 Performance Chemicals Segment 6 Service and Others Performance of each reportable segment is measured based on profit before finance cost, income tax, depreciation, amortisation and others which are included in the internal management reports that are reviewed by the Group’s CODM. Management believes that using profit before finance cost, income tax, depreciation, amortisation and others to measure performance is the most relevant in evaluating the results of certain segments relative to other entities that operate within these industries. 327 PTT GLOBAL CHEMICAL PUBLIC COMPANY LIMITED Form 56-1 One Report 2023
