This study aims to analyze the effect of investment decisions, capital structure, company size on profitability and Sustainable Growth, with profitability as a mediating variable and Financial Flexibility as a moderating variable. Data is obtained from secondary sources, namely audited financial reports from heavy construction and civil engineering subsector companies listed on the Indonesia Stock Exchange (IDX) for the 2019-2023 period. The analysis was carried out using Structural Equation Modeling based on Partial Least Squares (SEM-PLS). The results showed that investment decisions, capital structure, and company size have a significant effect on profitability. However, only company size has a significant effect on Sustainable Growth. Investment decisions and capital structure have no significant effect on Sustainable Growth. Profitability also has an insignificant effect on Sustainable Growth and does not mediate the relationship between variables. In addition, financial flexibility does not moderate the relationship between profitability and sustainable growth. This finding indicates that increased profitability is more influenced by investment strategy, capital structure, and firm scale, but does not necessarily translate directly into Sustainable Growth.

This study aims to analyze the influence of macroeconomic conditions, capital, and good corporate governance on earnings, financial risk, and yield to maturity bond, with bond rating acting as a moderating variable. The research focuses on banking companies listed on the Indonesian Stock Exchange (IDX). A Quantitative approach with a secondary data from Indonesian Stock Exchange (IDX) and Indonesian Bond Market Directory (IDMB) Purposive sampling method was applied, resulting in 102 active banking bond samples listed on the IDX during the 2020–2023 period. The hypotheses were tested using Structural Equation Modeling with Partial Least Squares (SEM-PLS). Out of 14 proposed hypotheses, 4 were supported with statistically significant results, while the remaining 10 were not. The results show that capital has a significant effect on financial risk, while earnings significantly influence both financial risk and bond yield to maturity. Overall, this study shows that internal factors like earnings and capital have a stronger impact on a company’s risk perception and debt cost than implementation good corporate governance and macroeconomic conditions. It also highlights the important role of bond ratings in reflecting a company’s reputation and credit quality in the banking bond market.
