This study explored the interplay between finance cost and shareholders wealth maximization of
listed oil and gas companies in Nigeria. It therefore focused on the positivist paradigm and
adopted the ex post facto method of research design. Four listed oil and gas companies were
randomly selected as samples for investigations. The annual financial statements of these
companies were the source of the secondary data collected for the study. Applying the Pearson
correlation model as the tool of analysis on the data gathered, the investigation showed that
finance cost does not significantly impact on price earnings ratio which indicated a negative
correlation of -0.018 with a significant value of 0.912. The investigation further revealed that
finance cost does not significantly impact EPS with a significant value of 0.614 and correlation
value of 0.082, the correlation is positive but very weak. The study concluded that finance cost
does not significantly impact on price earnings ratio and earnings per share of listed oil and gas
companies in Nigeria. Thus, the research recommended that the management should ensure
optimal gearing that would enhance earnings in order to boost companies P/E ratio without
overshooting debt servicing obligations; and that borrowed funds should be channeled to areas
that will boost profits in order to enhance EPS which is a key performance indicator.
