<![CDATA[P urpose – This research focuses on examining how company size, audit quality, and operational efficiency impact the financial performance of firms within the LQ45 index on the Indonesia Stock Exchange, which includes firms with the largest market capitalization and liquidity in Indonesia. Novelty – The uniqueness of this research is attributed to the concurrent use of audit tenure as an indicator of audit quality and Total Asset Turnover as a measure of operational efficiency, focused specifically on LQ45 companies during the 2022–2024 timeframe, which covers the post-pandemic recovery and the present economic environment. Method – This research utilizes a quantitative associative method by leveraging secondary data obtained from the annual financial reports of companies available on the official Indonesia Stock Exchange website. Samples were chosen through purposive sampling and examined using panel data multiple linear regression, with the Random Effect Model identified as the most suitable model. Findings – The findings suggest that company size and audit quality do not substantially influence financial performance, whereas operational efficiency has a significant and beneficial impact. At the same time, all three variables collectively have a substantial impact on the financial performance of LQ45 companies. Limitations and Implications – This research focuses exclusively on firms included in the LQ45 index, and its results may not apply to other industries or types of companies. The outcomes of this research can act as a guide for corporate leaders and policymakers in focusing on effective asset management as a crucial approach to enhancing financial performance.]]>
