This study examined the relationship between CEO tenure, sex, level of education, and organizational performance across 229 U.S. publicly traded pharmaceutical and biopharmaceutical companies. The Upper Echelons Theory was used to guide this research on how CEO characteristics could impact organizational performance. Fifteen hypotheses were developed and tested to evaluate the statistically significant relationship between CEO tenure, sex, level of education, and the organizational performance demonstrated in the abnormal stock return valuation and the number of FDA-approved drug products in clinical trial phases (phases 1, 2, and 3) for each company. This quantitative, non-experimental, and cross-sectional study was completed by conducting Multiple Linear Regression analysis and Negative Binomial Regression analysis to quantitative secondary data representing CEOs’ characteristics and their organizations. Study findings suggest that the length of CEO tenure had a positive statistically significant relationship with organizational performance. Our results showed that as a CEO’s tenure increases by one year, the abnormal stock return increases by 0.92%, and the number of drug products in the pipeline in phase 3 increases by a factor of 1.03 (3%). iv CEO sex and level of education did not indicate any statistically significant relationship with the abnormal stock return or the number of FDA-approved drug products in clinical trial phases (phases 1, 2, and 3).
