Evaluation of state support, its fairness and eligibility of criteria are quite common topics frequently investigated and discussed. Slovakia and similar after-transition countries use more or less direct aid to businesses in order to attract the attention of foreign investors or to support domestic ones. Following study focuses on effects of such aid in Slovakia, uses median values of financial indicators for description of the sample of supported businesses, indexes for analysis of dynamics in results and sources and Pearson’s correlation coefficients for expressing common relations between the size of aid and generated effects. Analysis revealed that companies benefiting from aid experienced initial growth in assets, sales, and profitability but these effects later faded. The correlation between the size of aid and financial ratios was rather insignificant, only in the case of sales, share of personnel cost and depreciation on added value confirmed positive and statistically significant correlation. Regional distribution of aid proved that the least developed regions received significantly less financial contribution, and incentives are not fully motivational in order to transfer investments to such regions.
