The drop in the crude oil price led to the stock loss of Baht 2,488 million or USD 1.02 per barrel against a reversal on Net Realizable Value (NRV) of Baht 1,026 million or USD 0.42 per barrel. Nevertheless, the company recorded the realized gain from oil hedging of Baht 339 million or USD 0.14 per barrel. All previous mentioned resulted in net inventory loss of Baht 1,123 million or USD 0.46 per barrel. Therefore, the Accounting Gross Integrated Margin (Accounting GIM) was Baht 18,221 million or USD 7.44 per barrel rising by 5% from that last year. Moreover, the earnings before interest, tax, depreciation and amortization (EBITDA) of Baht 5,754 million escalated by Baht 1,767 million or by 44%. In 2023, there was a gain on impairment and disposal of assets amounting to Baht 822 million, mainly owing to the reversal impairment on spare part. As a result, the company recorded the net loss of Baht 2,923 million in 2023 being less than the 2022 net loss by 33%. Net Sales Operating Performance 1.
