Black Box

Essar-controlled network and data centre integrator

Overview

Black Box reported consolidated FY2026 revenue of ₹6,322 crore, up 5.9% from ₹5,967 crore a year earlier[20]. The listed company was incorporated in 1986 by Tata Telecom to manufacture telecommunications equipment, later became AGC Networks, and now describes itself as an information and communication technology solutions provider and integrator[20]. The Essar Group held about 70% as of March 2026[20]. Black Box is an infrastructure-led outsourcer: much of its work involves designing, building and supporting networks and data centres rather than application development. It ranks 17th of the 50 companies here, behind KPIT Technologies, with revenue equal to 2.4% of that of TCS. Its year-on-year revenue change ranks 39th of the 47 companies for which a prior-year figure was available.
