We verify the moderating effect of managerial ambidexterity on the relationship between intellectual capital and financial performance of small manufacturing companies in Peru. The study used a quantitative, non-experimental, cross-sectional design. The sample consisted of 506 small manufacturing firms. To determine the hypothesised model's validity and reliability, we performed an exploratory factor analysis using a rotated component matrix to group questions within their corresponding constructs. Next, we assessed convergent and discriminant validity using measures such as Cronbach's alpha, composite reliability, and average variance extracted. Finally, we tested the model hypotheses using structural equation modelling. SPSS 27 and AMOS 24 were used for all analyses. The study showed that there is a partial moderating effect of managerial ambidexterity on the relationship between intellectual capital and financial performance of small manufacturing firms in Peru. Additionally, statistical analysis showed that managerial ambidexterity moderates the direct relationship between structural capital and relational capital with financial performance, while no moderation effect was observed for human capital. This study provides valuable information for academia and management as it is the first to analyse the relationship between intellectual capital and financial performance, considering the moderating effect of managerial ambidexterity in small manufacturing firms in Peru. This innovative approach makes a significant contribution to scientific knowledge by investigating how managerial ambidexterity affects the financial performance of businesses in emerging economies, an area that has received little prior research.
