Valamar Riviera d.d. is the largest hospitality and tourism company in Croatia, and tourism contributes significantly to the inflow of foreign capital each year, accounting for approximately one-fifth of the gross domestic product of the Republic of Croatia. During the observed period, the world was struck by the global COVID-19 pandemic, which particularly impacted the tourism sector. By analyzing the financial indicators of Valamar Riviera d.d. and conducting statistical data processing, this paper aims to present the impact of the global crisis on the company's operations, as well as its resilience to these challenges. Using statistical methods such as descriptive statistics and time series, the average revenue growth rates, variability of operating expenses, and changes in the liability structure will be calculated and interpreted. All results will be supported by tabular presentations of the calculations. In addition to the effects of the global pandemic, the paper aims to depict the seasonality of Croatian coastal tourism through the lens of the analyzed company, relying on available quarterly reports and tabular presentations of the calculations of indices and rates of changes in revenues, expenses, variations in liabilities and assets, quarterly revenue growth rates, indebtedness, and operating costs. Through the statistical analysis of time series, it will be shown in which quarter the company’s economic activity reaches its peak and whether this trend continues throughout all the years of the analyzed period. Based on the conclusions derived from the indicator analyses and statistical analyses conducted, the COVID-19 pandemic had a significant impact on the intensity of operations and revenue generation, as well as on the rapid recovery of highly liquid companies. Additionally, the pronounced seasonality of the company's operations in a specific quarter with a recurring trend in each year has been confirmed.
