Impact of capital structure and free cash flow on the efficiency of energy firms in Saudi Arabia

Several studies have examined the relationship between inventory management and firm performance. However, most of these studies ignore the impact of inventory types on the relationship. Moreover, the relationship is influenced by some factors such as cost of capital which has not been considered. This study examines the moderating effect of cost of capital on the relationship between inventory types and firm performance. The data of 48 firms for the period 2010-2016 which formed 279 firm-year observations were used in this study. With the use of Pearson correlation and panel Generalized Method of Moments (GMM) estimation, the findings show that inventory management with consideration of its types influence firm performance in the long term. In addition, it is also found that cost of capital moderates the relationship between inventory management and firm performance. However, the interaction between cost of capital and inventory types has different implications. It is suggested that firms should consider cost of capital when making decision on inventory types and align their inventory control to fit in to the changes in their business environment.

Due to the uniqueness of the services sector in terms of its characteristics and profitability, as well as the lack of studies on this sector, this study is considered to be the first to improve the knowledge of the key factors that play an important role in the profitability of the Jordanian services sector. This study investigates the effect of financial characteristics and capital structure on the profitability of all 46 services companies listed on the Amman Stock Exchange over the period 2014–2018. This study applies fixed and random effects models to panel data variables, namely, size, tangible assets, growth, business risk, debt to equity ratio and debt to assets ratio as independent variables. At the same time, profitability was measured by operating profits (earnings before interest and tax divided by total assets), return on assets (ROA), and return on equity (ROE), which acted as the dependent variables. This study reveals the first evidence that the debt to assets ratio has a negative and significant impact on the profitability of services companies in Jordan. In line with the pecking order theory, this finding suggests that more profitable services companies tend to prioritize the use of retained earnings in financing business activities rather than in financing debt. This study shows that profitability is significantly and positively affected by size and business risk, while ROA is negatively affected by business risk. It also shows that tangible assets have a negative and significant effect on profitability, while growth has a positive and significant effect on operating profits.

The aim of the article was to find out the optimal capital structure of the companies in relation to their maximum performance. To reach this aim, the data of the companies operating in the field of heat industry of the Slovak Republic were used. As the first method, a correlation matrix was applied. It was found out that there is statistically significant relationship between capital structure indicators and performance of the companies. Due to the lack of data in time series, the authors were not able to apply multiple regression model to assess the impact of these indicators on performance. Therefore, a method of modelling was used to analyze the impact of the change in capital structure on performance. Modelling was based on the principle of a gradual change in the capital structure in favor of debt. By the increase in debt, it was confirmed that there was a change in the values of selected indicators. In the course of analysis, it was confirmed that the value of EVA equity increased with the rising indebtedness by which the proposition I of the modified MM theory was supported. The performance expressed by EVA entity indicator is at its minimum when the capital structure is 90:10 in favor of equity. By increasing the debt, EVA entity rises. Based on these results, it can be stated that the performance of selected companies increases when the share of debt also rises, even when taking into account the rising financial risks.
