Governance as a Financing Signal: Board Formalisation and External-Finance Access Among SMEs in Saudi Arabia

This study examines board formalisation as a credibility signal for external financing among private small and medium-sized enterprises (SMEs) in the Kingdom of Saudi Arabia. Signalling theory suggests that the external-financing relevance of governance mechanisms is dependent on their observability, verifiability and interpretability. An external-finance analytic subsample consisting of 212 Saudi SMEs was derived from an original, bilingual (Arabic/English) survey dataset with 727 Saudi SMEs. The analysis applies bivariate signal heterogeneity tests on seven governance dimensions, six binary logistic regression specifications, and interaction models to condition on the age and size of the firm. SMEs with formal boards exhibit higher financing-access rates in unadjusted comparisons. However, the association weakens and falls just outside the conventional 5% significance threshold after controlling for firm size, age, and ownership generation. The structural governance index reaches nominal significance in the bivariate analysis (p = 0.033), but this association does not survive Holm multiple-comparison correction and is not statistically significant in the adjusted regression model (OR = 1.843, p = 0.361), indicating that governance signals are not uniformly associated with external-finance access. Signal credibility appears to be context-dependent: the board–finance association is stronger for older and larger firms. Causal inference is not justified in the case of a cross-sectional design. The findings have implications for governance support initiatives and financing-readiness programmes in Saudi Arabia and comparable emerging-market settings. These outcomes are components of sustainable economic development aligned with SDG 8 (Decent Work and Economic Growth) and SDG 10 (Reduced Inequalities) and with Saudi Vision 2030’s objectives for private-sector growth and financial inclusion.
