HIGHLIGHTS

MANAGEMENT COMMENTARY

Mr. Raju Vegesna, Chairman, said, “India’s emergence as a global growth hub is no longer a forecast. It is a present-day reality. India is set to become the third-largest economy by 2030-31 with projected annual growth of 6.7%, according to S&P Global.

This growth is underpinned by liberal economic reforms, a vibrant startup ecosystem, and a demographic dividend. With over 1.2 billion mobile phone users and the second-largest internet user base globally, India is now a important test-bed for emerging technologies such as AI, 5G, and cloud computing.

Government initiatives like ‘Digital India’ and ‘Startup India’ have further accelerated tech innovation, with India now home to over 100 unicorns. For global enterprises, the convergence of policy support, digital infrastructure, and deep talent positions India as a growth opportunity that is both immediate and immense.”.

Mr. M P Vijay Kumar, ED & Group CFO, said, “We remain committed to cost efficiency and fiscal discipline, aligning our financial strategies with long-term value creation across all our businesses. While we plan essential investments for future readiness, our current results face multiple headwinds of depreciation, interest expenses, and rising manpower costs. Our approach remains to invest to build resilience, enhance operational agility, and capture emerging opportunities.  The income tax expense includes tax, both current and deferred tax, of Rs.539 Million on profit of its data center subsidiary.

The cash balance at the end of the year was INR 6836 Million”.
