The study investigated the effect of audit committee structure on timeliness of financial report within the context of listed industrial goods companies in Nigeria. Specifically, the study examined, the frequency of audit committee meetings, the size of the audit committee, and the presence of non-executive directors on financial reporting lag. Employing an ex-post facto research design, the investigation focuses on 13 industrial goods companies listed on the Nigerian Exchange Group (NGX) between 2018 and 2022, drawing from secondary data sources such as annual reports. The study found a positive effect of audit committee meetings on audit reporting lag, suggesting that increased meeting frequency may inadvertently prolong the reporting process. Also, it found the significant effect of audit committee size on reporting lag, indicating that larger committees tend to experience prolonged reporting periods. Lastly, the presence of non-executive directors on the audit committee emerges as a contributing factor to extended reporting delays. Based on these findings, the study recommended that companies to prioritize the efficacy of audit committee operations, carefully deliberate on committee composition, and adhere steadfastly to best practices in corporate governance to streamline audit reporting processes.
