This study aims to examine the financial performance of the energy sector, which holds a significant position in the Turkish economy, in terms of selected indicators. The study utilizes financial statement data from 24 energy companies listed on Borsa Istanbul, whose data for 2023 is regularly accessible. The 2023 data of these energy sector companies is analyzed using the PSI method, one of the multi-criteria decision-making techniques. According to the PSI method, the alternatives were ranked, and ARESE was found to be the most successful company financially. The findings of this study suggest that when more criteria are included in performance evaluation studies, the differences in results can be observed in closer ranges and with greater sensitivity.
