JBM Auto and its associated component manufacturing entities, including Jay Bharat Maruti Limited, are promoted and controlled by the Arya family, led by industrialist S.K. Arya, who serves as the founder and chairman of the JBM Group. While the promoter group retains a significant majority and controlling stake in the corporate entities, shares are also publicly traded on Indian stock exchanges, meaning thousands of institutional and retail investors hold ownership stakes alongside the founding promoters.
