Forbes India has released the list of India's top 50 private sector companies based on several parameters.

The list, compiled by Forbes India in collaboration with PricewaterhouseCoopers India, does not rank but calls out companies measured over three years on these metrics — performance of stocks, sales growth and profitability of companies.

Customer-centric approach and strategic acquisitions have also been named as crucial common threads connecting the companies in the list.

Tech Companies Shareholders return in % Sales growth in % Return on equity %
HCL Tech 116 19 34
Infosys 76 16 25
Mindtree 202 26 29
TCS 70 20 42
Tech Mahindra 84 57 30

Mindtree provided the highest shareholders return, which indicates the full return on shares owned by investors over the three year period considered by Forbes, while Tech Mahindra registered the maximum growth in sales volume of its IT services export and TCS recorded the highest profitability from shareholders' investment.

Forbes highlighted HCL Technologies for narrowing the difference in revenue growth when compared to rival Wipro, and Infosys for re-inventing its services based on artificial intelligence. While HCL Technologies posted a 34 percent year-on-year growth in rupees for FY 2016, Wipro achieved a 9 percent revenue growth for the same fiscal.

"Efficiency of capital, the obsessive desire to stay differentiated from the clutter, the need to keep the customer at the centre of all they do and a keen eye on profitability bind this disparate group of companies," said Sourav Majumdar, editor of Forbes India.

The list features companies from vectors as diverse as IT, pharmaceuticals, banks and NBFCs, consumer goods, among others.
