This study
examines the influence of International Financial Reporting Standards (IFRS)
adoption on the earnings performance of publicly listed pharmaceutical firms in
Nigeria. The study adopts an ex-post facto research design using panel data
from five selected firms listed on the Nigerian Exchange Group (NGX) over the
period 2020–2024. Earnings performance is proxied by Return on Assets (ROA),
Return on Equity (ROE), and Earnings per Share (EPS). Data were analyzed using
descriptive statistics, correlation analysis, and panel regression techniques.
The findings reveal that IFRS adoption has a positive but statistically
insignificant effect on earnings performance. Firm size shows a positive and
significant relationship with performance, while leverage negatively affects
profitability. The study concludes that IFRS adoption alone does not guarantee
improved earnings performance without strong institutional enforcement. It
recommends enhanced regulatory compliance and corporate governance mechanisms.
