Stocks represent the fundamental type of long-term securities with a developed secondary market. In this thesis, the financial statements of the Croatian tourism companies – Valamar Riviera d.d., Maistra d.d. and Jadran d.d. were examined, focusing on their adaptability and resilience during the COVID-19 pandemic. By analyzing key financial indicators such as liquidity, profitability and investments, the overall financial situation of each company was examined. It also examined the implications of these analyzes for investors, including potential investment opportunities and risks. Using the discounted cash flow method (DCF method), the intrinsic value of the observed companies stocks was estimated and compared with the current market price, providing investors with a better insight into their potential value. The financial statements were analyzed to determine the companies' ability to adapt to the challenges of the pandemic and their financial stability in the post-pandemic period. It also examined how the companies managed to maintain stability and profitability despite unfavorable conditions. Ultimately, it was determined how safe the companies are for investment and whether they have potential for growth and development. Based on a detailed analysis, investors were given an insight into the intrinsic value and profitability of an investment in the shares of the tourism companies monitored. In particular, Valamar Riviera d.d. was identified as the safest company to invest in, with the potential for a good return in the future. Maistra d.d. also offers a safe investment, but with potentially limited returns, as the intrinsic value of the share is lower than the current market price. Jadran d.d., on the other hand, requires a more cautious investment approach and a willingness to take a higher risk.
