CAPITAL STRUCTURE AND PROFITABILITY OF SMALL PHARMACEUTICAL FIRMS: EVIDENCE FROM THE ALTERNATIVE INVESTMENT MARKET
Abstract
The relationship between capital structure and profitability remains
a critical issue for finance scholars and corporate decision-makers. While
prior studies have examined this relationship in the pharmaceutical
sector, limited attention has been given to small pharmaceutical firms.
This study investigates the impact of capital structure on the
profitability of small pharmaceutical companies listed on the
Alternative Investment Market (AIM) of the London Stock Exchange (LSE).
Using a five-year panel dataset (2018-2022), three regression models
(Ordinary Least Squares, Fixed Effects, and Random Effects) were
estimated with R statistical software. Profitability was measured by
return on assets (ROA) and return on equity (ROE), while capital
structure was captured through debt-to-equity ratio, short-term debt, and
long-term debt, with firm size included as a control variable. The
findings reveal a significant negative relationship between short-term
debt and ROA, and between debt-to-equity and ROE, while firm size
exhibits a positive relationship with both profitability measures. This
study extends existing literature by focusing on small pharmaceutical
firms, offering insights into their capital structure decisions
and the
implications for firm performance.
