Abstract

This study examines the effect of strategic management accounting (SMA) practices on the sustainable profitability of Nigerian listed companies. Specifically, it investigates the impact of Strategic Cost Management (SCM), Competitor Accounting (CA), and Performance Measurement Systems (PMS) on firm profitability. Using a quantitative approach, secondary data were collected from the annual reports of 10 listed companies over a 10-year period (2015–2025). Descriptive statistics and multiple regression analysis were employed to test the hypotheses. The findings reveal that all three SMA practices have a positive and significant effect on sustainable profitability. SCM improves efficiency and resource allocation, CA enables firms to respond effectively to competitors, and PMS enhances decision-making and operational performance. The regression model explains 67.8% of the variation in profitability, confirming the relevance of SMA practices in the Nigerian context. The study concludes that adopting SMA practices is crucial for achieving financial stability and competitive advantage. Firms are advised to strengthen cost management, monitor competitors, and implement robust performance measurement systems.
