Financial Performance of State-Owned Enterprises in Nigeria: Evidence from the South South Zone

State-owned enterprises occupy a significant role in Nigeria's mixed economy, serving as instruments of industrial policy, employment generation, and essential service delivery. However, their financial performance has consistently attracted criticism from policymakers, auditors, and development analysts. This study evaluates the financial performance of selected state-owned enterprises in the South South geopolitical zone, focusing on firms operating in the energy, transportation, and hospitality sectors. Using secondary data from audited financial statements and government enterprise performance reports for the period 2018 to 2022, the study employs financial ratio analysis and data envelopment analysis to measure efficiency, profitability, liquidity, and solvency. The theoretical framework draws on agency theory and the public choice theory to explain the governance deficiencies that commonly underlie state enterprise underperformance. The study reviews the impact of political interference in management appointment, poor revenue collection systems, and inadequate performance-based remuneration on organisational outcomes. Three case studies from Delta, Rivers, and Cross River States provide the primary empirical anchors. Existing literature consistently points to governance failures as the primary driver of poor state enterprise performance in sub-Saharan Africa, and this study tests whether structural reform measures in Nigeria's South South states have produced measurable improvements. Findings are expected to inform the Bureau of Public Enterprises, state governments, and development finance institutions supporting enterprise reform.
