Lakshmi’s father, Mohanlal Mittal, ran a steel business, Nippon Denro Ispat.[21] In 1976, due to the curb of steel production by the Indian government, the 26-year-old Mittal opened his first steel factory PT Ispat Indo in East Java, Indonesia. In 1989 Mittal purchased the state-owned steel works in Trinidad and Tobago, which were operating at an enormous loss. He turned them into profitable ventures in a year. Until the 1990s, the family’s main assets in India were a cold-rolling mill for sheet steels in Nagpur and an alloy steels plant near Pune. Prior to December 2001, Mittal had acquired assets which he renamed Ispat Mexicana and his Kazahkstani operation Ispat Karmet. That month he renamed Sidex Galati to Ispat Sidex, which he had acquired in November 2001.

In October 2003, the LNM Group succeeded in concluding the $155 million transaction to pry loose the Romanian government from the control of steel assets Siderurgica Hunedoara and Petrotub Roman, the day after it took over the PHS Steel Group which include Huta Sendzimira, Huta Katowice, Huta Florian and Huta Cedler from the Polish government. Mittal successfully employed Marek Dochnal’s consultancy to influence Polish officials in the 2003 privatisation of PHS steel group, which was then Poland’s largest. In 2006-07, Mittal succeeded in a hostile takeover bid for Arcelor, which he renamed Arcelor Mittal. In so doing he obtained control of amongst others the Usinor steel assets of France, the Arbed steel assets of Luxembourg, and the Aceralia steel assets of Spain.

In 2009, the Foundation along with Bharatiya Vidya Bhavan founded the Usha Lakshmi Mittal Institute of Management in New Delhi. SNDT Women’s University renamed the Institute of Technology for Women (ITW) as Usha Mittal Institute of Technology after a large donation from the Lakshmi Niwas Mittal Foundation.
