Abstract
The research investigated how the size of a company's board of directors influences the
connection between financial leverage and profitability in listed oil and gas firms in Nigeria. The
study included eight out of the nine oil and gas companies that were publicly listed as of
December 31, 2024.The data used in the analysis were collected from the audited annual reports
and financial statements of these selected firms over a span of thirteen years, from 2012 to 2024.
Various regression models were applied, all based on the Ordinary Least Squares (OLS)
method. The findings indicate that the ratio of long-term debt to total assets has a statistically
significant negative effect on profitability, which was measured using return on assets (ROA).
Furthermore, the study found that board size does not significantly influence the relationship
between financial leverage and profitability, which suggests that board size functions more as a
moderating rather than a direct factor. These results highlight that excessive reliance on debt
can harm a company's profitability and emphasize the importance of prudent debt management
within Nigeria's oil and gas sector. By focusing on the oil and gas industry in Nigeria, this study
contributes to the body of knowledge in this specific context. The research recommends that
companies in this sector should work towards enhancing their financial performance through
better debt management practices and ongoing monitoring.
