Kumar Mangalam Birla

Kumar Mangalam Birla became the chairman of one of India’s largest business groups at the age of twenty-eight, because his father died. He has spent the three decades since making it much larger, much more global and, in one painful case, much more exposed.

Four Generations

The Birla name has been one of the best known in Indian business for more than a century. His great-grandfather, G. D. Birla, built a large industrial empire in the first half of the twentieth century and was a close supporter of Mahatma Gandhi. The businesses were later divided among branches of the family.

His father, Aditya Vikram Birla, was one of the first Indian industrialists to build factories abroad, setting up plants in Thailand, Indonesia, Malaysia and the Philippines in the 1970s and 1980s. The group that Kumar Mangalam leads is named after him.

Calcutta and Bombay

Kumar Mangalam Birla was born on 14 June 1967 in Calcutta, to Aditya Vikram and Rajashree Birla. He grew up mainly in Bombay.

He took a commerce degree from the University of Bombay and then qualified as a chartered accountant, the demanding professional exam that most Indian businessmen of his background skip. He then went to London Business School for an MBA.

In 1989 he married Neerja Kasliwal. They have three children: Ananya, a singer and businesswoman who founded the microfinance company Svatantra; Aryaman, a former first-class cricketer for Madhya Pradesh who now works in the group; and Advaitesha.

Twenty-Eight

His father was diagnosed with prostate cancer and died in Baltimore on 1 October 1995, aged fifty-one. Kumar Mangalam Birla became chairman of the group almost immediately. He was twenty-eight.

The group he inherited had a turnover of roughly $2 billion. Many of its senior managers had worked for his father for decades, some for his grandfather before that. Plenty of people inside and outside the company doubted that a young accountant could hold it together.

He moved quickly and did not do what many expected. He brought in professional managers from outside the family’s traditional circle, introduced performance-linked pay, and retired some of the older executives. He also began simplifying a sprawling set of companies with overlapping ownership, a process that took years.

He also became, unusually quickly, a voice on how Indian companies should be run. In 1999, at thirty-two, he chaired the committee set up by the market regulator, SEBI, to write India’s first code of corporate governance for listed companies. Its recommendations — independent directors, audit committees, better disclosure — became the basis of the rules that listed Indian companies still follow.

Aluminium and Cement

His strategy was to be large in a few basic industries rather than small in many.

In aluminium, Hindalco bought Indian Aluminium Company (Indal) from Alcan in 2000. In cement, the group bought the cement business of the engineering company Larsen & Toubro in 2003–04 and combined it into UltraTech Cement. Through further purchases, including cement plants from Jaiprakash Associates and, in 2024, a controlling stake in India Cements, UltraTech became by far the largest cement maker in India.

Grasim, the group’s original flagship, remained a major producer of viscose staple fibre, a material made from wood pulp and used in textiles, and the parent of much of the group.

Novelis

The deal that defines his career came in February 2007. Hindalco agreed to buy Novelis, an American-Canadian company that was the world’s largest maker of rolled aluminium products — the sheets used in drinks cans, cars and buildings. The price, including debt, was about $6 billion.

It was an enormous bet. Hindalco was much smaller than the company it was buying, and the deal was financed largely with debt. Shares fell when it was announced, and the financial crisis that followed within eighteen months made it look worse.

Over time the bet paid off. Novelis became a major supplier of aluminium sheet to drinks makers and car companies, including for lightweight vehicle bodies, and grew into the largest part of Hindalco by revenue. It turned an Indian metals company into a global one.

Novelis kept buying. In 2020 it completed the purchase of Aleris, an American aluminium producer, for about $2.8 billion, adding plants in North America, Europe and Asia and strengthening its position in aerospace and car parts.

The group made other foreign purchases in the same years, including Columbian Chemicals, an American maker of carbon black, and Domsjö Fabriker, a Swedish maker of the specialty pulp used to produce viscose fibre, both in 2011. Each deal followed the same logic: buy a leading position in a basic material, then make it more efficient.

The Telecom Wound

Not every bet went well. The group had entered mobile telephony in the 1990s, and its operator, Idea Cellular, grew into one of India’s larger networks.

In 2016 Reliance Jio entered the market with free calls and very cheap data, forcing every rival to cut prices. To survive, Idea merged with Vodafone’s Indian business in 2018, forming Vodafone Idea, at the time the country’s largest operator by subscribers.

In October 2019 the Supreme Court ruled on a long-running dispute about how telecom companies should calculate the fees they owed the government. The ruling left Vodafone Idea with dues running into tens of thousands of crores of rupees. The company lost subscribers and money for years.

In August 2021 Birla wrote to the government offering to hand over his family’s stake to any entity the state chose, to keep the company alive. Soon after, he stepped down as non-executive chairman of Vodafone Idea. The government later converted part of the company’s dues into shares and became its largest shareholder.

It was the most public setback of his career, and he did not hide from it. Supporters point out that the group kept putting money into the company for years when walking away would have been cheaper; critics argue that the merger doubled the group’s exposure to a market it could not win. Both views are fair readings of the same facts.

Into the Shops

In recent years he has pushed the group towards consumers. Aditya Birla Fashion and Retail sells clothing brands. The group launched Birla Opus, a paint business, in 2024, taking on long-established rivals in a crowded market with a multi-billion-dollar investment. It also started Indriya, a jewellery brand, and expanded its financial services under Aditya Birla Capital.

He also finished the long job of simplifying the group’s structure. In 2017 Aditya Birla Nuvo was merged into Grasim, and the financial services business was listed separately as Aditya Birla Capital, giving investors a clearer view of what they owned.

These are businesses that sell to households rather than to factories, and they are a deliberate change from the metals and cement on which the group was built.

What He Built

Under his leadership the group grew from about $2 billion in revenue to more than $60 billion, with operations in dozens of countries. His wife, Neerja Birla, founded Mpower, a mental-health organisation, in 2016. He is chancellor of the Birla Institute of Technology and Science, Pilani, and the Government of India awarded him the Padma Bhushan in 2023. More than half of the group’s revenue now comes from outside India, which was not true of any Birla business when he took over.

The measure of him is the decision he made at twenty-eight: to stop behaving like the heir to a family business and start behaving like the chief executive of a global company. Novelis was the proof that it worked. Vodafone Idea was the reminder that even a good strategy can meet a bad market.
