Exploring the Joint Impact of Board Characteristics on Financial Performance and Corporate Sustainability

This paper explores how board characteristics influence financial performance and sustainability outcomes, combining four theories from management literature with an empirical analysis of 98 companies listed in the FTSE All-World Europe Index. The paper offers a short theoretical insight from Agency, Stakeholder, Stewardship, and Resource Dependence theories, offering details how board traits such as gender diversity, board size, independence, non-executive membership, CEO Chairman duality, and sustainability audit committees affect financial and sustainability outcomes. Rather than focusing on a specific industry or country, the review adopts an intersectoral and general perspective, showing how scholars conceptualize the governance–performance relationship. The empirical analysis evaluates the 98 companies to identify which board characteristics are most consistently associated with financial and sustainability performance and which theories best explain these patterns. Through the representative data obtained, but also through the correlation of theoretical knowledge, the study emphasizes the role of the board as being seen as an important component of corporate governance, a strategic factor of the company, and a key provider of results. The findings support the understanding of how governance systems can balance short-term financial goals with long-term environmental and social responsibilities, offering guidance for future research and practical governance implementation.
