Human Capital Development (HCD) has increasingly become a critical driver of organizational performance, particularly within knowledge-intensive manufacturing sectors. This study adopts an ex post facto research design to investigate how selected publicly quoted manufacturing companies in Nigeria account for and disclose HCD expenditures, and to examine relationships between these investments and financial performance. Using secondary data sourced from annual and sustainability reports of ten listed firms over five years (20182023), the research examines HCD disclosure extent and evaluates relationships between HCD expenditures (training and development, recruitment, and staff costs) and firm performance indicators: Return on Assets (ROA), Return on Equity (ROE), and Tobin's Q. Firm size was included as a control variable to account for organizational differences. Results demonstrate that training and development significantly impact ROA (F = 11.25, p < 0.01), ROE (F = 10.15, p < 0.01), and Tobin's Q (F = 8.95, p < 0.01), whilst recruitment and staff costs proved non-significant. Firm size remained significant only for ROA calculations. Findings reveal that HCD disclosures are generally inconsistent and inadequate across sampled firms, with limited integration into mainstream financial reporting. Despite some positive correlations between HCD spending and performance metrics, most relationships lacked statistical significance beyond training investments. The study highlights the pivotal role of training and development in driving both financial and market performance. It concludes that enhanced transparency, standardized HCD accounting practices, and stronger accountability mechanisms are essential for Nigerian manufacturing firms. Recommendations include regulatory incentives for improved HCD disclosure and further longitudinal research into the impacts of human capital investment on firm sustainability and long-term performance outcomes
