<![CDATA[Purpose – This study aims to examine the effect of leverage, liquidity, and firm size on the profitability of infrastructure sector companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. Design/methodology/approach – This quantitative study uses secondary data from the financial statements and official websites of infrastructure sector companies listed on the IDX. Census sampling with predetermined criteria resulted in 22 companies, of which 18 were included in the final analysis after outlier testing. Data were analyzed using multiple linear regression with SPSS version 27 following classical assumption tests. Findings – The results indicate that leverage and liquidity have significant effects on profitability, while firm size does not have a significant effect on profitability. Originality/value – This study provides empirical evidence on the determinants of profitability in Indonesia’s infrastructure sector during the post-pandemic recovery period and supports capital structure and trade-off theories in the context of emerging markets.]]>
