Nowadays, the analysis and management of enterprise performance is getting more and more attention than in the past due to the constantly changing global business environment bringing new, modern approaches to solve the issue in question. The main aim of this paper is to evaluate the financial performance of the health spa sector in Slovakia over the years 2012 – 2016 with use of selected modern financial methods. Based on the results, relatively identical values were achieved within the application of both modern methods (EVA in € and RONA in %). When evaluating the performance of Slovak spa sector as a whole, the best results were achieved in year 2015 and, on the contrary, year 2012 was identified as the worst-performing one. In this regard, a positive continuous performance growth was recorded over the period of 2012 − 2015, but this optimistic trend was influenced negatively by a sharp drop in net profit in the following year 2016. According to the results of EVA and RONA application, the best-performing enterprises within the analysed spa sector were Spa Bojnice, Spa Lúčky, Spa Dudince and Spa Štós. Contrary, the worst-performing enterprises over the years 2012 – 2016 were Spa Brusno, Spa Sliač, Horezza and Spa Číž. To conclude, some recommendations for improving the current financial performance of the selected group of spa enterprises in Slovakia were formulated.
