Abstract:
The objective of this study is to examine the impact of financial leverage on corporate
growth among firms listed on the Colombo Stock Exchange (CSE) in Sri Lanka. This
research is important, as limited empirical studies have addressed the leverage–
growth relationship in the Sri Lankan context, where firms face unique challenges
such as underdeveloped capital markets and high reliance on debt financing. Financial
leverage is assessed using the total debt-to-equity ratio (TDTE) and the debt-to-total assets ratio (TDTA), while corporate growth is measured through sales growth, asset
growth, market capitalization growth, return on assets growth, and return on equity
growth. A quantitative approach was adopted, utilizing panel data from 38 high market-capitalization firms across 20 industries over the period 2020–2024.
Descriptive statistics, correlation analysis, and panel regression models were
employed to analyze the data. The findings indicate that TDTE has a statistically
significant positive impact on market capitalization growth, while TDTA exerts a
significant negative influence on sales growth and market capitalization growth.
However, neither leverage measure shows a significant effect on asset growth, ROA
growth, or ROE growth. These mixed results suggest that while equity-based leverage
can enhance market valuation, excessive asset-linked debt constrains revenue
generation and investor confidence. The study contributes to the existing literature by
providing empirical evidence from an emerging market context where research is
scarce. It further emphasizes the importance of balanced debt management for
corporate managers and highlights policy implications, encouraging regulators to
improve access to equity financing and strengthen capital market mechanisms to
support sustainable capital structures.
