On 7 June 2021, one of India’s richest men wrote a letter offering to give a business away.

The letter went from Kumar Mangalam Birla to the Cabinet Secretary, Rajiv Gauba. Vodafone Idea, the phone company Birla chaired, owed Rs 1.80 lakh crore and had lost Rs 44,233 crore in a single year. “It is with a sense of duty towards the 27 crore Indians connected by VIL,” he wrote, “I am more than willing to hand over my stake in the company to any entity—public sector/government/domestic financial entity or any other that the government may consider worthy of keeping the company as a going concern.” [89]

Two months later he stepped down as chairman. [90]

Nearly five years later, on 5 May 2026, he took the chair again, days after the telecom department cut the company’s biggest disputed bill by 27%. [98][97]

That swing, from offering to walk away to coming back to finish the job, tells you a good deal about the man. Birla is the heir nobody expected to cope: a 28-year-old handed a group with revenue of about Rs 8,000 crore when his father died in 1995. [53] He has since raised its turnover 33 times, to about US$67 billion, mostly by buying companies that others thought too big or too risky. [13] In September 2026 the M3M Hurun India Rich List ranked “Kumar Mangalam Birla & family” sixth among 1,810 wealthy Indians, with about Rs 2.69 lakh crore. [43][44]

This is the story of how he did it, what it cost him, and the questions that have followed him along the way.

Where it began

Kumar Mangalam Birla was born on 14 June 1967 in Calcutta and grew up in Mumbai. [39] He was born into the most famous business name in India.

The Birlas trace their start to 1857, when Seth Shiv Narayan Birla began trading cotton from Pilani, a small town in the Rajasthan desert. [53] His grandson Ghanshyam Das Birla, born in Pilani in 1894, turned a trading house into an industrial one, starting with a jute mill in 1919. G.D. Birla was also a close confidant of Mahatma Gandhi, who was assassinated at Birla House in Delhi on 30 January 1948. [23]

Two of the companies Kumar Mangalam runs today date from that era. Grasim was incorporated on 25 August 1947, ten days after Independence. [53] Hindalco followed in 1958. [24]

G.D. Birla was Kumar Mangalam’s great-grandfather, and the boy spent a lot of time with him. He died when Kumar was 15. “For me, he was one of my best friends,” Birla told CNN in 2011. [48]

His grandfather, Basant Kumar Birla, chaired Century Textiles [57] and lived with a plainness that is hard to picture in a billionaire family. “He had five kurtas and dhotis and three suits. That was about it,” Birla recalled on Nikhil Kamath’s podcast in December 2024. [55]

His father was a different sort. Aditya Vikram Birla came of age when the licence raj limited how much an Indian business house could grow at home, so he went abroad. In 1969 he set up Indo-Thai Synthetics in Thailand, the group’s first overseas venture. [22] He went on to build 19 companies outside India, in Thailand, Malaysia, Indonesia, the Philippines and Egypt. [53] “My father was more of a risk-taker, wanting to expand his business outside the country more aggressively,” his son said. [55]

A childhood inside the business

Birla went to Campion School in Mumbai and took a commerce degree at H.R. College of Commerce and Economics. [41][39][40] (Some profiles name Sydenham College instead; IIM Ahmedabad’s official profile of him and H.R. College’s own alumni list both say H.R. College.)

What he wanted next was an MBA. What his father wanted was a chartered accountant. On Kaun Banega Crorepati in December 2025, Birla recalled the ruling he was given: without becoming a CA, there would be no place for him in the office. [56] He qualified as a CA, and only then went to London Business School, graduating with the MBA class of 1992. [25][38]

The real schooling happened at home and at work. “It’s like I’ve been in a management school since I was 15 or 16,” he once said. [49] By his own account he worked with his father for “almost seven, eight years”, held independent charge of a couple of businesses, and shadowed him closely for three or four years. [48]

Then the apprenticeship ended without warning. On 1 October 1995, Aditya Vikram Birla died in the United States. [54] He was 51. [48] His only son was 28.

The first break

For an heir, the first break is not a lucky order or a first loan. It is the moment people stop waiting for you to fail.

In October 1995 they were waiting. The companies Aditya Birla controlled had revenue of over Rs 8,000 crore, 55 plants and 75,000 employees. [53] A profile written a decade later recalled that observers had dismissed the new chairman as too young, and expected him to stumble. [50] He has admitted to the fear and pressure of those months. [56] He has also said: “I think I was much better prepared than most people thought I was.” [48]

His first moves were about people, not deals.

In 1996 he brought all the companies under one name, the Aditya Birla Group. [53] He set a retirement age, in a group that had never had a formal one. More than 350 managers above the age of 60 left. [49] They were given notice, a two-year grace period and extra compensation, and a few trusted veterans stayed on to run key companies. [51]

Then he hired outsiders into senior jobs. Santrupt Misra came from Hindustan Lever in February 1996, aged 30, to run human resources for the whole group. [51] “We went in for lateral induction from outside the group,” Birla said later. “Now we have a more diverse basket of skills in the organisation, much more than what we had before.” [49] Asked about those years, he said: “It was a very tough process.” [50]

His grandfather measured the shift precisely. “In terms of management style, the change from GD Birla to me was 10 per cent; from me to Aditya was 25 per cent. But from Aditya to Kumar Mangalam it was 75 per cent,” B.K. Birla said. [49]

Not everything changed. Birla kept parta, the old Marwari system of tracking costs and profit daily. “It is a timeless concept and can be applied even 20 years from now,” he said. [51]

The outside world noticed. In May 1999 SEBI appointed a Committee on Corporate Governance under his chairmanship; he was 31 and a member of the SEBI board. Its recommendations, that at least half of a company’s board be non-executive directors and that every listed company have an independent audit committee, were written into stock-exchange listing rules from 2000-01. [4] Indian companies know the rule that followed as Clause 49.

Then came the first deals. In December 1999 the group bought Madura Garments, the maker of Louis Philippe, Van Heusen, Allen Solly and Peter England. [60] In 2000 Hindalco bought Alcan’s 54.6% stake in Indian Aluminium (Indal) and a further 20% through an open offer, spending over Rs 1,000 crore. [61]

The young man in his father’s chair had shown he could change the old house and add to it. The big bets came next.

Building the empire

Birla’s method has stayed the same for three decades: find an industry where the group can be first or second, then buy scale faster than it can be built. The group counts more than 60 acquisitions under him. [13]

Cement: the L&T gambit and the race to 200 million tonnes

In 2001 Grasim bought a stake of about 10.5% in Larsen & Toubro from the Ambanis’ Reliance. [52] (Mukesh Ambani appears in this story more than once.) It was the opening move in a three-year siege. In 2004 L&T’s cement business was carved out as UltraTech; Grasim bought 8.5% of it from L&T and made an open offer for 30% more, taking control with 51% and a combined capacity of 31 million tonnes a year. [62]

From there UltraTech mostly bought its growth:

• 2017: Jaiprakash Associates’ cement plants, 21.2 million tonnes, for Rs 16,189 crore. [33]
• 2018: Binani Cement, won with a Rs 7,950 crore bid after a court fight with Dalmia Bharat (see below). [63]
• 2024: The India Cements. UltraTech agreed to buy the promoters’ 32.72% for Rs 3,954 crore and took control that December. [64][34]
• 2025: The cement business of Kesoram, a company his grandfather once chaired, lifting capacity to about 183 million tonnes. [35][57]

In April 2026 UltraTech crossed 200 million tonnes of capacity in India. [17] Birla’s speech that day was the clearest statement of his creed. “It took us 36 years to reach 100 million tonnes. The next 50 million followed in five. The 50 after that, in just over two,” he said. And: “Back in 2019, I had said that scale is not everything. It is the only thing.” [18]

The urgency has a name. In 2022 Gautam Adani bought Ambuja Cements and ACC for US$10.5 billion and set a target of 140 million tonnes by 2028. [59][65] Analysts read much of UltraTech’s recent buying as Birla protecting that lead. [59]

Aluminium: Novelis, the deal everyone hated

On 11 February 2007 Hindalco agreed to buy Novelis, a North American maker of rolled aluminium for drink cans and cars, for US$44.93 a share. Including about US$2.4 billion of debt, the price was about US$6 billion. [7] The deal closed on 15 May 2007. [30]

Almost nobody liked it. Forbes later recorded that Hindalco’s shares fell 14% the day after the announcement. [67] Even Hindalco’s own managing director, Debu Bhattacharya, had doubts. “The sheer scale was daunting. I felt we would be biting off more than a mouthful,” he said. [67]

Birla overruled the doubters. He has called it “an intuitive call” and “an entrepreneur’s call”. [48] At the time he said simply: “When you are acquiring a world leader, you will have to pay a premium.” [66]

The next two years nearly proved the critics right (that story is in the next section). But Novelis recovered. By 2011 it was earning US$754 million a year at the operating level, and Birla allowed himself one line: “Our acquisition was written off, but the results are now there for everyone to see.” [67] In 2018 he said the group’s real capital in Novelis had been about US$3 billion, against a value he put at US$11-12 billion. [68]

He doubled down. Novelis bought the US firm Aleris at an enterprise value of US$2.8 billion, closing the deal in April 2020 in the first weeks of the pandemic. [32] By 2025 Birla could say the group had invested over US$15 billion in America, which he said made it the largest Indian investor in the United States. [69]

Telecom, carbon black, fashion and finance

Telecom began as a venture with AT&T and the Tatas. [52] In April 2006 Birla bought out the Tatas’ 48.14% for Rs 4,406 crore. [70] Idea Cellular listed in March 2007, [83] and by early 2015 was worth Rs 58,700 crore on the stock market. [52] What happened after that is the hardest chapter of his career.

Other bets were quieter and worked:

• Carbon black. In 2011 the group paid US$875 million for Columbian Chemicals of the US, doubling its capacity and making Birla Carbon the world’s largest producer of the material that strengthens tyres. [36]
• Fashion. In 2012 it bought Pantaloons for Rs 1,600 crore, adding department stores to the Madura brands. [52]
• Finance. In August 2016 Birla announced the merger of Aditya Birla Nuvo into Grasim and the spin-off of financial services. [71] Aditya Birla Capital listed on 1 September 2017 with a market value of over Rs 55,000 crore. [72]

The consumer turn

For most of its life this was a group that sold to other businesses: metal, fibre, cement, chemicals. “As a group, we were historically more focused on B2B spaces,” Birla wrote in January 2026. [14]

That is changing, and fast.

In February 2024 Grasim launched Birla Opus, a paints business built from scratch with Rs 10,000 crore, six plants and 1,332 million litres of annual capacity. [16] Reuters reported in 2025 that the entry, with deep dealer discounts, had helped pull the market share of leader Asian Paints down to 52% from 59%. [73] At Grasim’s annual meeting in August 2026, Birla said Opus had doubled revenue in a year and reached a revenue share of about 10%. [74]

In July 2024 came Indriya, a jewellery chain backed by Rs 5,000 crore. [75] In February 2025 UltraTech announced Rs 1,800 crore for wires and cables; its own shares fell about 5% on the news. Birla’s answer to the sceptics was the usual one: “We want to be number one or two in every business that we are in or get into.” [76]

Two deals in 2026 show how wide the net now is. In March a consortium of the Aditya Birla Group, the Times of India Group, Bolt Ventures and Blackstone agreed to buy the Royal Challengers Bengaluru cricket franchise from United Spirits for Rs 16,660 crore (about US$1.78 billion), with his son Aryaman named as chairman. [19] The Competition Commission cleared it on 30 June. [77] In July, Aditya Birla Renewables agreed to buy Sprng Energy from Shell at an enterprise value of Rs 17,200 crore, a deal expected to close by 31 December 2026. [78]

Scale, and how the wealth is held

The group today reports turnover of about US$67 billion, a combined market value of about US$112 billion for its listed companies, a presence in 41 countries and 227,500 employees. [13]

Birla’s own wealth is not cash. It is a chain of shareholdings.

• The promoter group owned 43.74% of Grasim on 31 March 2026, mostly through private family companies such as Birla Group Holdings (23.18%) and IGH Holdings (6.64%). [9]
• It owned 34.64% of Hindalco, which owns Novelis outright. [10]
• Grasim in turn owns 56.11% of UltraTech and controls Aditya Birla Capital. [9]

So when UltraTech or Hindalco shares move, the family’s fortune moves with them. From June 2026 there is also a small direct stream: Grasim, Hindalco and Novelis are to pay Birla Group Holdings a brand royalty of 0.25% of revenue, capped at Rs 225 crore a year for each company. [79]

Hurun’s 2026 list valued “Kumar Mangalam Birla & family” at Rs 2,68,700 crore, up 15% in a year. [44] Even so he slipped a place, from fifth in 2025, [45] and now sits one rank behind Roshni Nadar Malhotra. Forbes, which uses a different method, put him at US$22.7 billion in mid-September 2026. [46] A separate Barclays-Hurun study in August 2026 ranked the family’s businesses the second most valuable in India, at Rs 8.1 lakh crore, behind only the Ambanis. [47]

The setbacks and failures

Novelis, 2008: when the bet looked fatal

Hindalco had financed Novelis with a bridge loan of about US$3 billion. [80] To repay part of it, the company launched a Rs 5,047 crore rights issue in 2008, just as markets collapsed. Shareholders took up only about half; the rest fell on the underwriters. [81]

Then the global financial crisis hit demand. Novelis reported a net loss of US$1.8 billion for the December 2008 quarter, including a US$1.5 billion write-down of goodwill. [82] Bhattacharya called the period “a christening by fire”. [67]

Birla did not sell. A cost-cutting programme called Project Sunrise saved US$140 million, and the recovery in demand did the rest. “We have a last-man-standing philosophy that has helped us weather difficult times,” he told Forbes. [67]

Vodafone Idea: the long emergency

Idea was profitable until late 2016, when Mukesh Ambani’s Reliance Jio arrived with a free trial offer and set off a price war. For the quarter ending December 2016, Idea reported its first loss since listing. [83]

Birla’s answer was size. In March 2017 he agreed to merge Idea with Vodafone’s Indian arm. [6] The merger closed on 31 August 2018, creating India’s largest operator by subscribers, with over 408 million of them, Birla as chairman, and net debt of about Rs 1.09 lakh crore. [15]

Then the law landed on it.

On 24 October 2019 the Supreme Court upheld the government’s wide definition of “adjusted gross revenue” (AGR), on which telecom licence fees are charged, and with it years of unpaid fees, interest and penalties. [2] The telecom department’s demand on Vodafone Idea was Rs 58,254 crore. [84] The company reported a quarterly loss of Rs 50,921 crore, described at the time as the worst in Indian corporate history. [85][86] Bloomberg calculated that Birla’s own net worth had fallen by about US$3 billion in two years. [86]

On 6 December 2019 he said publicly what promoters rarely say. “It does not make sense to put good money after bad. That would be end of story for us. We will shut shop,” he told a newspaper summit in Delhi. [87]

The years that followed were a slow negotiation between a sinking company, its two owners and the state:

• September 2020: the Supreme Court gave operators 10 years to pay. [88]
• June-August 2021: Birla’s letter offering his stake to any entity the government chose; his exit as chairman. By then subscribers were down to 267.8 million. [89][90]
• September 2021: the Cabinet’s telecom package: a moratorium of up to four years on dues and an option to pay the interest in shares. [5]
• February 2023: the government converted Rs 16,133 crore of interest into equity, taking about 33%. “We had sought a firm commitment that Aditya Birla Group would run company and bring necessary investments. Birlas have agreed,” said telecom minister Ashwini Vaishnaw. [91] Birla rejoined the board that April. [92]
• April 2024: an Rs 18,000 crore follow-on public offer, the largest India had seen. [93]
• April 2025: a further Rs 36,950 crore of dues converted; the government’s stake rose to 48.99% and the Aditya Birla Group’s fell to about 9.5%. [94]
• May 2025: the Supreme Court dismissed fresh pleas for a waiver as “misconceived”. [84]
• October-December 2025: the Court allowed the Centre to reconsider the dues as a matter of policy; [95] the Cabinet then froze them at Rs 87,695 crore, payable between FY32 and FY41. [96]
• 30 April 2026: after a reassessment, the telecom department fixed the dues at Rs 64,046 crore. [97]

Five days later Birla was chairman again. [98] In June shareholders approved a fresh Rs 4,730 crore from an Aditya Birla Group entity. [99]

“Tough Times Don’t Last. Tough Companies Do,” he wrote in his annual note that January. “For the first time in years, the fog has cleared, allowing the business to look beyond survival.” [14]

The fog has not fully lifted. The company lost Rs 3,754 crore in the April-June 2026 quarter and has about 193 million subscribers, less than half the number it began with. [100] Bloomberg reported on 11 September 2026 that a State Bank of India-led group had agreed to lend about US$3.5 billion, on condition that Birla stays chairman for the life of the loan; the report cited unnamed people and the deal had not been formalised. [101] As of 30 September, Business Standard reported, the funding gap for its Rs 45,000 crore network plan was still to be bridged. [102]

The ventures that did not work

Not every bet was rescued.

• More supermarkets. Launched in 2007, the food retail chain ran up accumulated losses of Rs 5,320 crore over eight years. [103] In a deal announced in September 2018 it was sold to Samara Capital and Amazon at an enterprise value of Rs 4,200 crore. [104]
• Payments bank. Aditya Birla Idea Payments Bank opened in February 2018 and announced its closure in July 2019, citing “unanticipated developments in the business landscape that have made the economic model unviable”. [105]
• abof.com. The online fashion store launched in 2015 and shut on 31 December 2017. [106]
• A full bank. In April 2014 the Reserve Bank gave new bank licences to only two of 25 applicants, IDFC and Bandhan; the Birlas were among those turned down. [107][52]
• The Novelis listing. A US share sale that would have valued Novelis at up to US$12.6 billion was postponed in June 2024, with the company citing market conditions. [108][31]
• Bay Minette. Novelis’s new plant in Alabama was budgeted at US$2.5 billion in 2022. The estimate rose to US$4.1 billion in February 2024, when Hindalco’s shares fell about 14% in a day, and to US$5 billion in November 2025. [109][110]
• Oswego. Two fires, in September and November 2025, shut the hot mill at Novelis’s plant in Oswego, New York; it restarted in June 2026, and Hindalco booked Rs 2,299 crore of related costs, net of insurance, in the April-June 2026 quarter. [111][12]

Controversies and allegations

The coal block case (Talabira-II), 2013-2026

Allegation: In October 2013 the Central Bureau of Investigation (CBI) registered a case naming Birla, former coal secretary P.C. Parakh and officials of Hindalco and the coal ministry. It alleged criminal conspiracy and misuse of official position in the 2005 allocation of the Talabira-II and III coal blocks in Odisha, and searched premises in four cities. [112] The CBI’s case was that a screening committee had recommended the block for a public-sector company, and that the decision was changed to accommodate Hindalco after its representations. The block was finally shared: 70% to Neyveli Lignite, 15% to Mahanadi Coalfields and 15% to Hindalco. [118]

Response: The group denied wrongdoing. [112] The office of the then Prime Minister, Manmohan Singh, who had held the coal portfolio in 2005, confirmed that the final decision differed from the committee’s recommendation “following a representation received in the Prime Minister’s Office from one of the parties”, and said: “The Prime Minister is satisfied that the final decision taken in this regard was entirely appropriate and is based on the merits of the case placed before him.” [113] Hindalco said in 2015 that none of its officials, including Birla, had “pursued any unlawful or inappropriate means for securing the allocation of the coal block”. [118]

What happened next:

• In August 2014 the CBI itself filed a closure report, saying the evidence did not substantiate the allegations. [114]
• In September 2014 the Supreme Court, in separate proceedings, cancelled 214 coal block allocations made since 1993. Hindalco lost its Talabira and Mahan blocks and put the one-time cost at around Rs 500 crore. [115]
• In December 2014 the special court declined to accept the closure report and asked the CBI to record Dr Singh’s statement. [116]
• On 11 March 2015 special judge Bharat Parashar summoned Dr Singh, Birla, Parakh and others as accused, for offences including criminal conspiracy and criminal breach of trust. [117][118]
• On 1 April 2015 the Supreme Court stayed the summons and the trial-court proceedings. [119]
• On 29 July 2026 a Supreme Court bench led by Chief Justice Surya Kant allowed Dr Singh’s appeal, set aside the March 2015 summoning order and accepted the CBI’s closure reports, holding that the trial judge had no good reason to reject them. Dr Singh had died in December 2024. [120]
• Separately, Hindalco disclosed that in another CBI case, over alleged misuse of coal from a de-allocated mine, a special court discharged the company and all other accused on 30 May 2026. [12]

Status: No trial ever began, and Birla has not been convicted of anything in this matter. The July 2026 order was passed in Dr Singh’s appeal. Outlook reported that the CBI told the court that issues concerning other accused might need separate consideration, and the reports available as of 1 October 2026 do not record a separate final order in the appeals filed by Birla and Hindalco. [121]

The 2013 raids and the “Birla-Sahara papers”

Allegation: During the coal-case searches in October 2013, income-tax officials found about Rs 25 crore in unaccounted cash at the Delhi office of Aditya Birla Management Corporation and seized documents and the laptop of a senior group executive, Shubhendu Amitabh. Tax investigators later alleged undisclosed income of Rs 203.18 crore and cash moved through hawala operators. [122][1] One note read “Gujarat CM - 25 cr (12 Done - rest?)”. [123] In 2016 the NGO Common Cause, represented by lawyer Prashant Bhushan, asked the Supreme Court for a court-monitored investigation into these and similar papers seized from the Sahara group. Delhi Chief Minister Arvind Kejriwal and Congress leader Rahul Gandhi alleged that the note recorded a payment to Narendra Modi when he was Chief Minister of Gujarat. [123] This remains an unproven claim.

Response: Amitabh told investigators these were “purely personal notes” and that the entry referred to “a business development at Gujarat Alkali Chemicals”. [1] He also claimed the cash as his own. [122] The group said in January 2015 that reports had been “quoted totally out of context” and that it was “taken aback” and “concerned” about the money. [122] Birla said in December 2016: “I don’t even know about it and I do not wish to talk on that issue. The matter is subjudice.” [124]

What happened next:

• On 11 January 2017 Justices Arun Mishra and Amitava Roy dismissed the plea. They held that the Birla and Sahara materials “are not maintained in regular course of business and thus lack in required reliability to be made the foundation of a police investigation”, and that “no case is made out to direct investigation against any of the persons named in the Birla’s documents”. [1]
• Critics of the ruling, writing in Scroll, noted that the tax department’s own report had not accepted Amitabh’s explanation, and argued that only an investigation could settle the questions. [125]

Status: Closed by the Supreme Court in 2017. No investigation was ordered, so the claim of payments to politicians was never tested and no one was charged. The final outcome of the income-tax proceedings has not been made public.

Cement cartel penalties

Allegation: In an order of 31 August 2016 the Competition Commission of India (CCI) held that cement makers, including UltraTech, had coordinated prices and production through their industry association, in breach of the cartel provisions of the Competition Act. It was a re-hearing of a case first decided in June 2012 and sent back by the appellate tribunal in December 2015. [3] UltraTech’s accounts put its penalty under that order at Rs 1,616.83 crore (including a business it later absorbed), and record a second CCI order, of 19 January 2017, for Rs 68.30 crore. [8]

Response: UltraTech appealed. It says in its 2025-26 accounts that, “backed by legal opinions”, it “believes that it has a good case” and has made no provision. [8]

What happened next:

• The appellate tribunal, NCLAT, rejected the appeal against the 2016 order. On 5 October 2018 the Supreme Court stayed that ruling, subject to a deposit of 10% of the penalty, Rs 161.68 crore. [8]
• A separate CCI investigation into rigging of cement tenders floated by ONGC covers The India Cements for 2017-18, before UltraTech took control in December 2024. UltraTech said in July 2025 that it “is not under investigation” in that case; Reuters reported in March 2026 that a final order was awaited. [126][127]

Status: UltraTech’s appeals were still pending before the Supreme Court in its latest accounts. The penalty is not final.

Grasim and the viscose fibre case

Allegation: On 16 March 2020 the CCI found that Grasim had abused its dominant position in viscose staple fibre between 2012 and 2017, through discriminatory pricing and conditions imposed on buyers, and levied a penalty of Rs 301.61 crore. [9][128]

Response: Grasim appealed, and in November 2020 NCLAT stayed recovery against a 10% deposit. [9]

What happened next:

• On 5 May 2026 NCLAT set the order aside and sent the matter back to the CCI for a fresh hearing. Its reason was procedural: the Commission had differed from its own investigation arm without giving Grasim a chance to respond. The tribunal said it was making “no comment on the merits”. [128]
• In the paints market the roles are reversed. On Grasim’s complaint, the CCI ordered an investigation into Asian Paints over alleged pressure on dealers; in October 2025 the Supreme Court declined to interfere, and Asian Paints withdrew its challenge. [129]

Status: The fibre case is back before the CCI. No fresh order had been reported as of 1 October 2026.

Electoral bonds and the Vodafone Idea rescue

Allegation: On 15 February 2024 the Supreme Court struck down the electoral bonds scheme and ordered donor details to be published. [130] Working from that data, Scroll and its reporting partners calculated that Aditya Birla Group companies bought bonds worth nearly Rs 556 crore between April 2019 and January 2024, of which Rs 285 crore went to the BJP and Rs 264.5 crore to the Biju Janata Dal, then in power in Odisha. The report pointed out that three group companies bought Rs 100 crore of bonds on 12 December 2022, which the BJP encashed, about two months before the government converted Vodafone Idea’s dues into shares. [131] Hindalco’s own accounts confirm Rs 100 crore given through bonds in 2023-24, and Rs 362 crore to the Aditya Birla General Electoral Trust in 2024-25. [11]

Response: Scroll said its questions to the group went unanswered. [131] The donations were legal under the scheme then in force. The option to convert dues into government equity was part of the September 2021 telecom package and was open to all operators, [5] and the minister said the conversion followed the group’s commitment to run and fund the company. [91]

Status: No court or regulator has found any link between the donations and a government decision, and no proceedings on the point are known. The inference from timing is the reporters’ own and is unproven.

The Binani Cement bid, 2018

Allegation: In the insolvency of Binani Cement, lenders first chose a Dalmia Bharat company as the winning bidder. UltraTech then made a higher revised offer. Dalmia argued that it came too late, and that if bids could keep being revised there would be “no finality to the process”. [132]

Response: UltraTech’s position, which the tribunals accepted, was that its offer paid creditors more: Rs 7,950 crore against the rival’s Rs 6,932 crore. [63]

What happened next:

• On 14 November 2018 NCLAT approved UltraTech’s plan and found the rival plan “discriminatory” between creditors. [133]
• On 19 November 2018 the Supreme Court upheld that ruling, and UltraTech completed the Rs 7,950 crore purchase. [132][63]

Status: Concluded in UltraTech’s favour. No court found wrongdoing by the company or by Birla.

As of 1 October 2026, no court has convicted Kumar Mangalam Birla of any offence. The competition penalties on his companies are either under appeal or have been sent back for rehearing.

Giving back

The Birlas have built schools, hospitals and temples for generations, and the family’s giving is still organised more like an institution than a personal cause.

The group’s social work runs through the Aditya Birla Centre for Community Initiatives and Rural Development, chaired by his mother, Rajashree Birla. It reports reaching over 9,000 villages and 11 million people, with 24 hospitals and 54 schools. [28] His wife, Neerja Birla, is the founder and chairperson of Mpower, a mental-health initiative of the Aditya Birla Education Trust. [42]

Education is where Birla himself is most visible:

• The Aditya Birla Scholarships, set up in 1999 in his father’s memory, had supported 781 scholars by their 25th year. [134]
• In 2019 a £15 million endowment created the B.K. Birla Scholars Programme at London Business School, funding 10 MBA students a year. [37]
• He is chancellor of BITS Pilani, the university his great-grandfather founded. [23] It opened a Rs 1,500 crore campus near Mumbai in February 2024, [135] and in July 2025 he announced a Rs 2,200 crore expansion, including an AI-focused campus at Amaravati. [136]

In April 2020 the group committed Rs 500 crore to Covid-19 relief, of which Rs 400 crore went to the PM-CARES fund. [20] The EdelGive Hurun India Philanthropy List 2025 ranked “Kumar Mangalam Birla & family” fourth, with Rs 440 crore given in the year. [137]

“In a corporate context, giving back is not generosity, it is almost a responsibility,” he has said. [58]

The state has returned the compliment. He joined the Reserve Bank of India’s central board in 2006, [138] has chaired the boards of IIM Ahmedabad and IIT Delhi, [13] received the Padma Bhushan in March 2023 [139] and an honorary doctorate from the University of London in November 2025. [140]

In person he remains what a 2006 profile found: a teetotaller and vegetarian who reads management books and enjoys Hindi films. [50]

Succession

Birla is 59 and has announced neither a retirement date nor a successor. What he has done is put the next generation on the boards.

On 30 January 2023 his two elder children, Ananya and Aryaman Vikram, joined the board of Aditya Birla Fashion and Retail and of Aditya Birla Management Corporation, the group’s apex decision-making body. [141] They joined Grasim’s board a week later [29] and Hindalco’s in August 2024. [142]

Both arrived with businesses of their own.

Ananya Birla founded Svatantra Microfin at 17. In August 2023 it bought Chaitanya India Fin Credit for Rs 1,479 crore, becoming the second-largest microfinance company of its kind in the country. [143] In May 2024 she gave up a parallel career in music to concentrate on business, calling it “the hardest decision”. [144]

Aryaman Vikram Birla, a former first-class cricketer, founded Aditya Birla Ventures and now leads the group’s portfolio strategy along with its fashion, renewables, hospitality and venture-capital businesses. [26] He is to chair Royal Challengers Bengaluru under the 2026 deal. [19]

Their father’s public position is that the family is not the point. “Our business is not a family-run business, it is a people-run organization,” he said in 2024. [58] The structure supports the claim: professional “business directors” run each company. [21]

The open question is how control of a pyramid of holding companies will eventually pass to the next generation. Birla has not said. His mother, Rajashree Birla, still sits on the boards of Grasim, Hindalco and UltraTech. [27]

What their journey teaches

1. An inheritance is a starting line, not a finish. Birla received Rs 8,000 crore of revenue and a famous name. Most of what the group is known for today, including Novelis, UltraTech and the consumer brands, was added after 1995. Heirs are judged on what they build with what they were given.

2. Change the people system before you change the portfolio. His first big decisions were a retirement age and outside hiring, not an acquisition. The deals of the 2000s were possible because the managers who would run them were already in place.

3. A bold purchase is only half a decision; the other half is holding it through its worst year. Novelis looked like a mistake in 2008, with a half-subscribed rights issue and a US$1.8 billion quarterly loss. The value came from not selling at the bottom.

4. In a regulated business, say plainly what you will not do. “We will shut shop” and the 2021 letter were not bluster. They told the government exactly where the promoter’s commitment ended. The rescue that followed left the state owning nearly half the company, which is its own lesson about who really controls a licensed industry.

5. Scale is a moat, and a magnet. Being the largest in cement and fibre brought market strength, and also two competition cases that have run for years. A leader should budget for scrutiny the way it budgets for capacity.

6. Keep the old discipline under the new strategy. Birla retired the old guard but kept parta, the daily cost sheet. Modernising did not mean throwing away the habit that made the family careful with money.

On 1 October 1995, exactly 31 years before this profile was written, a 28-year-old lost his father and gained 55 factories. He has since turned them into one of the largest business groups in Asia, lost and regained his footing in telecom, and spent more than a decade answering questions in court. The work of handing it on has only just begun.
