Purpose: The study examines the effect of internal communication on employee performance in Malian companies, with organizational commitment as a mediating factor. It specifically investigated how communication practices influence employee attitudes and performance outcomes through commitment.

Methodology/Design: A quantitative research design was employed using a cross-sectional survey of 300 employees across multiple sectors in Mali. Data were analyzed using Structural Equation Modeling (SEM) to test both direct and indirect relationships between internal communication, organizational commitment, and employee performance.

Findings: Results revealed that internal communication significantly influenced employee performance (β = 0.312, p < 0.001) and organizational commitment (β = 0.457, p < 0.001). Organizational commitment also partially mediated the relationship between internal communication and employee performance (indirect β = 0.214, p < 0.001), confirming its role as a critical pathway linking communication to performance outcomes.

Implications: The study provides practical guidance for managers and HR practitioners in Malian companies to improve employee performance through effective communication systems, two-way feedback, and policies that foster organizational commitment.
