Indonesia's economic development in 2017 grew 5.07% higher than in 2016 which was only 5.03%. Especially growth in the transportation sub-sector experienced a growth of 8.49% on an annual basis. Economic development in the transportation sub-sector will certainly invite investors to invest, therefore information about a company's financial statements is needed. Information about the condition of the company's financial statements is very necessary to determine the company's financial performance. This study aims to examine the effect of liquidity, solvency and company size on the company's financial performance in transportation sub-sector companies for the period 2015-2017. The financial performance of the company is the dependent variable in this study, while the liquidity, solvency and size of the company are independent variables. The sampling method used is a sampling method with certain considerations (purposive sampling). The research method in this study is associative, while the analytical technique used in this study is multiple linear regression analysis. The results of the regression test show that 34.1% of the factors that affect the company's financial performance can be explained by the variables of liquidity, solvency and company size. The remaining 65.9% was explained by other factors not studied in the study. The existence of the F test shows that simultaneously the variables of liquidity, solvency and company size simultaneously have a significant effect on the company's financial performance. The results of the t test showed that liquidity and solvency variables did not have a significant effect on the company's financial performance with the calculated analysis values of (1.951) and (-0.602) respectively which were smaller than the table (2.01954). While the variable size of the company has a significant effect on the company's financial performance with a calculated analysis value (4,773) or greater than the table. Thus, the larger the size of the company, the company's financial performance will increase.
