The aim of this research was to analyze the annual financial statements of AD Plastik d.d. In order to determine the financial position and the performance of this divestment. This activity covered the business of AD Plastik in the period from 2013 to 2016. The joint stock company AD Plastik is the largest Croatian manufacturer of plastic parts for the automotive industry. The analysis of the balance sheet and profit and loss account was carried out using horizontal and vertical analyzes. On the basis of the analysis of the balance sheet, buildings, plant and equipment within the long-term assets are the most significant item since they are the most important factor of the production process. Also, the company invests heavily in the development of new products during the observed period of 2013, thus making the intangible asset gained significance. The investment cycle ends in 2014, after which there is no significant increase in profitability due to the serial production of a large number of development products. The Edison project started in 2015 had the greatest impact on the growth in production. In the period from 2013 to 2016, the Company achieved a positive financial result thanks to the increase in revenue from sales of products at new locations and the increase in revenues from the development and production of tools. On the other hand, operating expenses mainly relate to the costs of raw materials and materials and staff costs. Business performance analysis was also carried out using financial indicators. Profitability indicators with operating margin and net profit margins are gradually decreasing. The company is largely financed from its own resources. Liquidity indicators have shown that we are not sure whether this company will have short-term liabilities to settle short-term liabilities.
