Here’s a challenge. Using the five clues below, identify the company that is being talked about here.

1 I began my journey about five decades ago, founded by two brothers born to a stock-broking father. Both brothers graduated from the same IIT.

2 My promoters continue to maintain maximum permissible stake despite 10 times growth in my market capitalisation over the last 10 years.

3 Though my net profits have more than doubled over the last five years, my stock price has grown over seven times..

4 Post-listing, I took more than seven years to come above my listing price. Thanks to strong stock performance in recent years, I had a billion-dollar market capitalisation for a week or two only.

5 I have subsidiaries in four out of top five economies of the world and I am globally the second-largest manufacturer of one of my key products.
