Human Capital Development Disclosure and Financial Performance of Quoted Telecommunications Firms in Nigeria (2010-2022)

This study examined the relationship between human capital development disclosure and financial performance of quoted telecommunications firms in Nigeria from 2010 to 2022. The purpose was to address the gap in empirical evidence on whether Training and Development Disclosure (TDD) and Health, Safety, and Welfare Disclosure (HSWD) affect financial performance in the Nigerian telecommunications sector. The study adopted a longitudinal ex-post facto design with a census sample comprising MTN Nigeria Communications Plc and Airtel Africa Plc over 13 years (2010–2022), yielding 26 firm-year observations. TDD and HSWD were measured using content analysis based on sentence counts, while financial performance was measured by Return on Assets (ROA). Data were analysed using descriptive statistics, a correlation matrix, and pooled Ordinary Least Squares regression with diagnostic tests conducted using EViews 11. The key findings reveal that neither TDD nor HSWD has a statistically significant effect on ROA, leading to rejection of both hypotheses. Severe multicollinearity between TDD and HSWD (r = 0.998) indicates that Nigerian telecommunications firms do not distinguish between these disclosure categories in practice. The model explains only 8 percent of variation in ROA, suggesting other factors are more influential drivers of financial performance. The practical implications are that managers should improve disclosure quality by providing quantitative, outcome-orientated metrics; investors should use HCD disclosure as a soft signal for long-term value creation; and regulators should mandate standardised, comparable HCD metrics in annual reports.
