How Ambuja Cement Turned Two Traders With Zero Manufacturing Knowledge Into India's $10.5 Billion Cement Empire

In 1981, two commodity traders from Mumbai—Narotam Sekhsaria, a 31-year-old cotton trader, and Suresh Kumar Neotia, an established industrialist—made a decision that seemed insane to everyone who knew them.

They would enter the cement manufacturing business.

Neither had manufacturing experience. Neither understood cement production chemistry. Neither had worked in construction or heavy industry. Sekhsaria had built his career trading cotton in Gujarat markets. Neotia had industrial investments but no cement expertise.

When they approached the Gujarat Industrial Investment Corporation (GIIC) seeking support for a cement plant in Kodinar, Gujarat, skeptics questioned their credentials. The cement industry was capital-intensive, technologically complex, and dominated by established players with decades of experience. What could two traders possibly achieve?

On October 20, 1981, they incorporated Gujarat Ambuja Cements Limited. The name "Ambuja"—derived from Sanskrit meaning "born of water"—symbolized purity and growth. In 1983, after securing financing combining promoter equity with term loans from Indian financial institutions, they formally launched operations.

Forty-four years later, in May 2022, Gautam Adani's conglomerate acquired Ambuja Cement and its subsidiary ACC from Holcim for $10.5 billion—India's largest-ever M&A transaction in infrastructure and materials. By April 2025, Ambuja's capacity exceeded 100 million tonnes per annum (MTPA), making it India's second-largest cement manufacturer with targets of 140 MTPA by 2028.

This is the story of how two traders with zero manufacturing knowledge built one of India's most efficient cement companies—and how their "farsightedness" transformed a commodity into a brand synonymous with strength.

The Founders: Cotton Trader Meets Industrialist

Narotam S. Sekhsaria was born in 1950 into a Marwari trading family in Rajasthan and raised in Mumbai. His early career centered on cotton trading in Gujarat—buying from farmers, selling to mills, mastering commodity markets' volatility and margins.

Suresh Kumar Neotia brought complementary strengths: industrial experience, capital access, and business networks. Together, they identified an opportunity: India's infrastructure boom required massive cement quantities, yet the industry remained fragmented with high transport costs, inconsistent quality, and inefficiencies everywhere.

Their insight? Build integrated plants near limestone deposits with captive port facilities, use advanced kiln technology, and prioritize logistics efficiency over production scale alone. This logistics-first, vendor-partnership approach would differentiate Ambuja from competitors.

1981-1986: Building the First Plant

After incorporation in October 1981, Sekhsaria and Neotia focused on their first plant at Kodinar, Gujarat (later renamed Ambujanagar). The location was strategic: abundant limestone reserves, proximity to Gujarat's coast enabling bulk cement transport by sea—unprecedented in India—and GIIC support facilitating land acquisition and initial funding.

But building a cement plant from scratch when you've never manufactured anything proved brutal. Every decision required learning: kiln temperatures, clinker ratios, fuel optimization, environmental controls. Leading chemists told them their vision was impossible. They persisted.

In 1986, the first integrated cement plant commenced operations at Ambujanagar with initial capacity of 0.7 million tonnes per annum (MTPA). The plant achieved over 100% capacity utilization within six months—extraordinary for a greenfield project by first-time manufacturers.

Their secret? Operational efficiency. While competitors focused on maximizing capacity, Ambuja obsessed over minimizing costs per tonne. Low power tariffs, fuel optimization, minimal manpower requirements, and logistics innovation created some of the lowest global production costs by the early 2000s.

1990-1993: Scaling Through Public Markets

By 1990, Ambuja received approval for a second plant—1 MTPA facility at Darlaghat, Himachal Pradesh. In 1993, a second unit at Ambujanagar added another 1 MTPA.

The same year, Ambuja launched its Initial Public Offering (IPO)—India's first cement company to issue Global Depository Receipts (GDRs), raising $60 million. The public listing provided capital for expansion while subjecting Ambuja to market discipline and transparency.

By 1995, annual capacity reached 1.5 million tonnes. The company that skeptics dismissed in 1981 was now a serious player.

The Innovation: Sea Transport Revolution

Ambuja pioneered bulk cement transport by sea in India—a logistics revolution that competitors dismissed as impractical.

Traditional cement distribution relied on trucks and trains, limiting range and increasing costs. Ambuja built captive port facilities at its coastal Gujarat plants, loading cement directly onto ships that delivered to coastal cities across India at a fraction of land transport costs.

This innovation expanded Ambuja's market reach dramatically while maintaining cost leadership—a combination competitors couldn't match.

1990s-2000s: The "I Can" Culture

Beyond logistics, Ambuja pioneered something equally important: brand-building in a commodity business.

Under Sekhsaria's leadership, Ambuja transformed cement from faceless commodity into premium consumer product. The iconic "I Can" slogan emphasized strength, reliability, and quality. Humorous advertisements built emotional connections with end-users—contractors, engineers, individual home builders.

The positioning worked. Ambuja commanded premium pricing despite operating in a commodity market. The brand became synonymous with strength and trust.

Internally, "I Can" became cultural philosophy. "Give a man orders, and he will do the task reasonably well," Sekhsaria explained. "But let him set his own targets, give him freedom and authority, and his task becomes a personal mission."

This empowerment culture attracted talent and drove performance that competitors struggled to replicate.

1999-2005: The ACC Acquisition

In 1999, Ambuja made a bold move: acquiring equity stake in ACC Limited—India's oldest and largest cement manufacturer, previously controlled by Tata Group.

By early 2005, under Narotam Sekhsaria's chairmanship of Gujarat Ambuja Cements Ltd (GACL), the company had acquired controlling stake in ACC. Sekhsaria joined ACC's board, overseeing productivity gains between 1999-2005 that he later documented in his book.

The acquisition demonstrated that the traders who knew nothing about cement in 1981 had learned enough to acquire and improve India's most established cement company.

2006: The Holcim Sale

In January 2006, Holcim—Switzerland's global cement giant—bought 14.8% promoters' stake in Gujarat Ambuja Cements for Rs 2,140 crore. Over subsequent months, Holcim increased its stake until holding 61.62% controlling interest.

Why did Sekhsaria sell?

Multiple factors converged. Sekhsaria had been diagnosed with cancer—creating urgency around succession planning and estate organization. The ACC acquisition had stretched Ambuja's resources. Holcim offered global expertise, technology access, and capital for expansion.

From 2006-2022, Holcim controlled Ambuja while Sekhsaria remained non-executive chairman—first of Ambuja (2006-2009), then both Ambuja and ACC (2009-2022), guiding strategy without day-to-day management.

2015: The Lafarge-Holcim Merger

In 2015, Holcim merged with France's Lafarge to form the world's largest building materials company. In India, this created a dominant player rivaling UltraTech.

But the Competition Commission of India (CCI) required the merged entity to divest 5 MTPA capacity for merger approval. Lafarge's Indian capacity sold to Nirma in 2016 for $1.4 billion, creating another significant cement player.

April 14, 2022: Holcim's Exit Announcement

On April 14, 2022, Holcim announced it would exit the Indian market after 17 years—part of a strategy refocusing on core markets. Holcim listed its stakes in Ambuja Cements and ACC for sale.

The announcement triggered intense bidding. Multiple conglomerates coveted India's second-largest cement platform. But one bidder had deeper pockets than all others combined.

May 15, 2022: The Adani Acquisition

On May 15, 2022, Gautam Adani's Adani Group announced definitive agreements acquiring Holcim's entire stake in Ambuja Cements (63.19%) and ACC (54.53%, of which 50.05% held through Ambuja) for approximately $10.5 billion.

The transaction was transformative:

• Largest-ever acquisition by Adani Group

• India's largest-ever M&A in infrastructure/materials

• Instantly made Adani India's second-largest cement manufacturer with ~70 MTPA combined capacity (Ambuja + ACC)

• Combined market capitalization: $19 billion

On September 16, 2022, the Adani Family, through special purpose vehicle Endeavour Trade and Investment Ltd, completed the acquisition. An open offer for additional 26% from public shareholders followed.

"Our move into the cement business is yet another validation of our belief in our nation's growth story," declared Gautam Adani.

2022-2025: The Adani Expansion Blitz

Under Adani ownership, Ambuja embarked on aggressive expansion:

December 2023: Acquired Sanghi Industries (Saurashtra) for Rs 5,185 crore

June 2024: Acquired Penna Cement (Hyderabad) for Rs 10,422 crore enterprise value, adding 14 MTPA

October 2024: Acquired Orient Cement (CK Birla Group) for Rs 8,100 crore, adding 16.6 MTPA (8.5 MTPA operational + 8.1 MTPA ready-to-implement)

April 2025: Orient Cement acquisition completed, taking total capacity to 100.3 MTPA (88.9 MTPA + 8.5 MTPA Orient + 2.4 MTPA Farakka expansion + 0.5 MTPA debottlenecking)

July 2025: NCLT approved merger of Adani Cementation (AEL subsidiary) with Ambuja, adding limestone reserves of ~275 million tonnes at Lakhpat, Gujarat, plus manufacturing unit at Raigad, Maharashtra

Target: 140 MTPA by FY 2027-28

The Current Scale

As of 2025, Ambuja operates:

• Capacity: 100+ MTPA

• Plants: 24 integrated plants, 22 grinding units

• Market Position: India's second-largest cement manufacturer (after UltraTech's 183 MTPA)

• Parent: Adani Group

• Products: OPC, PPC, blended cements, clinker

The company that started with 0.7 MTPA in 1986 now produces over 100 MTPA—a 143x increase in 39 years.

The Legacy

From Narotam Sekhsaria's cotton trading to 100+ MTPA capacity, from zero manufacturing knowledge to $10.5 billion acquisition value—Ambuja's 44-year journey proves timeless truths.

First, domain expertise isn't prerequisite for success. Sekhsaria and Neotia knew nothing about cement. They learned, hired experts, and built systematically.

Second, logistics matter as much as production. Ambuja's sea transport innovation created competitive moats that outlasted patents.

Third, culture drives performance. The "I Can" philosophy empowered employees to achieve seemingly impossible targets.

Fourth, timing matters. Entering cement in 1981—just as India's infrastructure boom began—positioned Ambuja perfectly for decades of growth.

Finally, knowing when to sell is as important as knowing what to build. Sekhsaria's 2006 Holcim sale and Holcim's 2022 Adani sale both represented pragmatic exits at optimal valuations.

When construction workers use Ambuja cement to build India's roads, bridges, airports, and homes, they're using a brand built by two traders who were told they'd fail because they knew nothing about manufacturing.

Narotam Sekhsaria proved that not knowing how something is "supposed" to be done sometimes allows you to do it better than experts ever imagined.

That's not just building a cement company. That's proving that farsightedness, learning agility, and execution excellence matter more than pedigree—one tonne, one plant, one innovation at a time.
