This study aims to determine the influence of good corporate governance on firm fundamental performance, stock performance, and firm value of companies (main and comparing samples) during the period of 2012-2020 (9 years). The good corporate governance is proxied by using ASEAN Corporate Governance Scorecard explained in The Globe and Mail guidelines, where the score is taken from the firm’s annual report. There was a total of 18 main and 8 comparing samples selected purposively. The data was analyzed using panel data regression. The results show that partially indicators of good corporate governance have significant value to Return on Asset and Firm Value, but indicators of good corporate governance have no significant value to Stock Performance.
