This paper examines how C-suite attributes influence firms' financial performance and assesses the mediating role of supply chain finance. Using panel data from 156 non-financial firms listed on the Pakistan Stock Exchange (2016–2024) and 2,646 observations, Fixed Effects and Random Effects Modelling techniques were applied. Results show that C-suite attributes significantly shape performance, with industry experience emerging as the most influential factor. Leverage and firm age negatively affected performance, whereas corporate governance strengthened profitability. The study highlights how executive traits translate into financial outcomes through operational finance pathways. This study contributes to finance literature by showing that C-suite attributes influence firm performance in varied ways across accounting and market-based measures. Executive networks and financial education enhance market valuation but do not necessarily improve profitability, while industry experience consistently supports efficiency and firm value. The study integrates supply chain finance into performance models, highlighting working capital efficiency and liquidity as key transmission channels. Overall, it extends Upper Echelons Theory by showing how executive traits shape performance through signaling and operational mechanisms. This study is unique in exploring the C Suite attributes with a mediating role of supply chain finance, using panel data from Pakistan.
