This study aims to analyze the financial impact of the COVID-19 pandemic on the airline and healthcare industries in OECD countries from a comparative perspective. The pandemic has created a crisis that has reshaped economic and sectoral dynamics globally. In this context, the study analyzes the key indicators affecting the financial performance of publicly traded companies operating in the airline and healthcare industries. In the analysis, stock prices are used as the dependent variable, while independent variables include earnings before interest, taxes, depreciation, and amortization (EBITDA) margin, liquidity ratio, free cash flow, total revenue, asset turnover, return on assets (ROA), and return on equity (ROE).
According to the results of the analysis conducted using the panel data analysis method, the liquidity ratio and total revenue exhibit a positive and statistically significant impact on stock prices in the airline industry. In the healthcare industry, the EBITDA margin and total revenue also demonstrate statistically significant and positive effects on stock prices. In both industries, asset turnover shows a statistically significant negative relationship with stock prices. The remaining variables do not exhibit statistically significant effects.
