Purpose This study aims to examine the moderating role of chief executive officer (CEO) power on the relationship between divestiture strategy and firm performance by framing the relationship under the agency and power circulation theories. Design/methodology/approach This study focuses on a sample of 319 non-financial public-listed companies in Malaysia from the year 2012–2016 and estimates the model under two-step generalized method of moments panel regression to eliminate the endogeneity issue. Findings The results show that divestiture strategy decreased the firm performance. Meanwhile, greater CEO power changed that divestiture effect but still failed to increase the performance. This study also indicates the CEO power strengthens the relationship between firm performance and divestiture. Research limitations/implications The overall findings show that the positive moderating role of CEO power on the relationship between divestiture and performance. This research confirmed the agency and power circulation theories by showing that CEO power can make divestiture strategy works. However, the moderating plot tells different. CEO power may strengthen the relationship between divestiture and performance; it fails to boost up the performance in overall. Therefore, this study is about CEO power on the strategic decision and gives a good implication for corporate governance concerning the impact of CEO power on the organization’s alignment process. Originality/value This study examines the effect of CEO power on the performance of divestiture strategy implementation by contesting the agency and power circulation theories within an emerging country context.
