Abstract: The paper analyzes the relationship between ownership structure and corporate governance quality in Croatian joint-stock companies listed on the Zagreb Stock Exchange. The purpose of the research is to determine the extent to which ownership concentration and the type of majority owner influence the level of compliance with the Corporate Governance Code and business performance indicators. The empirical analysis was conducted on a sample of 30 companies using data from annual reports, financial indicators, and corporate governance reports for 2024. Methods of descriptive statistics, correlation analysis, and t-tests were applied. The results show that ownership in the observed companies is highly concentrated, but concentration is not statistically significantly related to the level of formal compliance with the Code. At the same time, the number of independent supervisory board members shows a negative relationship with return on equity (ROE), while the type of owner shows limited but visible influence on governance practices. The contribution of the paper is manifested in the empirical confirmation of contemporary theoretical insights into the role of ownership in shaping governance quality in developing markets such as Croatia.
