The impact of the financial structure on the company's profitability depends on several factors, including the industry type, company size, and market conditions. If the company uses debt moderately according to its ability to repay it, it can contribute to increasing profitability by achieving higher profit margins due to effective debt utilization. However, if the company is heavily indebted, it may face challenges in repaying debts and incur high financial costs, negatively impacting its profitability. Therefore, companies should manage their financial structures wisely to ensure a balance between achieving profitability and reducing financial risks by choosing suitable financing options that meet their needs and provide sustainable financial stability.otherfinancial structure, financing structure, optimal capital structureThesis
