Ambuja Cements Limited
Ambuja Cements makes and sells cement, the powder that gets mixed with sand, gravel, and water to make concrete for buildings, roads, and bridges.
Ambuja Cements is one of India's biggest cement makers. It sells the grey powder that holds together almost everything people build — homes, offices, roads, and bridges. Builders, construction contractors, and ordinary people mixing cement for a small project all buy it. The company sells under the Ambuja brand, along with ACC and a few specialty products, and it also sells ready-mix concrete that arrives at a site already mixed and ready to pour.
Cement is a heavy, cheap-per-bag product, so the business is really a logistics game. A bag of cement costs little but weighs a lot, which means it is expensive to truck very far. That is why cement makers fight to own plants spread across the country and to keep transport distances short. Ambuja runs limestone mines and factories mostly in northern and western India, and being close to both the raw rock and the customer is a big part of whether a plant makes money. The other huge cost is energy — coal and power to fire the kilns that turn limestone into cement. When fuel prices jump, profits get squeezed, which is why the company keeps investing in ways to run its plants more cheaply. The industry itself is a bit of an oligopoly. A handful of large players dominate, including UltraTech Cement and Shree Cement, and they compete hard on price while also watching each other's capacity plans. Because cement demand tracks construction, the business rises and falls with the economy: busy building years mean strong sales, slow years mean price wars. In recent years the sector has been consolidating, with big groups buying smaller ones to gain scale and bargaining power over fuel and freight. Ambuja itself went through a major ownership change. It was long part of the Holcim group, a global building-materials giant based in Switzerland. In 2022, India's Adani Group bought Holcim's controlling stake in Ambuja and ACC, making Adani the new owner and turning Ambuja into a key piece of a much larger Indian infrastructure empire. Since then the company has been pushing to expand capacity and cut costs, aiming to compete at the very top of the Indian cement market, where UltraTech is the clear leader.
Cement is a simple product with a simple pitch: it is essential, hard to substitute, and sold in enormous volumes. The catch is that it is also a commodity — one bag is much like another — so the winners are usually the ones with the lowest costs, the best plant locations, and the strongest distribution networks. Ambuja's bet is that scale, smart logistics, and its new parent's deep pockets can keep it in that winners' circle as India keeps building.

BIG PICTURE
Ultratech sells nearly twice as much cement in India as Ambuja and ACC combined
- 15% Ambuja and ACC
- 29% Ultratech
- 8% Shree Cement
- 8% Dalmia Bharat
- 40% Others
In India's cement market, Ultratech holds 29% while Ambuja and its sister brand ACC together hold 14 to 16%, with the midpoint at 15%. Shree Cement and Dalmia Bharat each control 8 to 9%, taken as 8% here, and the rest of the market is split among smaller players. Ambuja mainly earns money selling cement in India, so this gap with the market leader is the central fact of its competitive position. Source: LinkedIn post by Fabian Warislohner, data from 2026
Timeline
A Cement Business Takes Shape
In 1981, a group of promoters including N.S. Sekhsaria and the state industrial corporation set up Ambuja Cements as a private company. They signed equipment agreements with Krupp Polysius, the German engineering firm, which gave the young venture the machinery it needed to build its first cement plant. The idea was simple: India needed cement, and someone had to make it.
Going Public as Gujarat Ambuja
Two years later the company became a public limited company and took the name Gujarat Ambuja Cements. Going public was a way to raise money from outside investors — a bigger pool of capital than a private promoter group could provide on its own.
The First Bag of Cement
In 1986 the company finally started producing cement. Until then it had been a plan and a set of contracts; now it was a real cement maker with a plant running and a product to sell.
Holcim Takes Control
In 2006, Holcim, one of the world's biggest cement companies, bought management control and raised its stake past half of the company. That put the Indian cement maker inside a global giant's fold — and it would stay there for the next 16 years, a rivalry-tinged chapter in Indian cement that would help shape the industry.
A Shorter Name
A year later the company dropped "Gujarat" from its name, becoming simply Ambuja Cements. It was a small change but a deliberate one: the shorter name matched the brand people already used, "Ambuja", and travelled better outside its home state.
Ambuja Buys into ACC
In 2013, Ambuja's board approved a plan to acquire just over half of ACC, another large Indian cement company. The mechanics were two-step: Ambuja would first buy a 24% stake in Holcim India, then merge Holcim India into itself. The result was that Holcim's Indian cement operations were consolidated under Ambuja — two brands, one owner.
Holcim Exits, Adani Arrives
In 2022, Holcim announced it would leave India after 17 years and put its stakes in Ambuja and ACC up for sale. The Adani Group bought those stakes for about 10.5 billion US dollars, and Ambuja changed hands — from a Swiss cement major to an Indian conglomerate building an empire.
The Hindenburg Shock
The new ownership was barely settled when, in January 2023, a short-seller called Hindenburg Research published a report accusing the Adani Group of stock manipulation and accounting fraud. Ambuja's share price plunged around 25% in a single day, its biggest fall since 2006. The story of who owned the company had suddenly become the story of how much investors trusted the owner.
Buying Sanghi Industries
Later that year, Ambuja bought Sanghi Industries for a little over 5,000 crore rupees. The point was size: the deal pushed its cement-making capacity up to about 75 million tonnes a year, a step toward becoming one of the country's largest producers.
A Southern Buying Spree
In 2024, Ambuja kept spending. It bought Hyderabad-based Penna Cement for about 10,400 crore rupees, extending its reach into southern India, and then bought CK Birla Group's Orient Cement for roughly 8,100 crore rupees. Together with the earlier deals, these purchases made Ambuja the centre of an aggressively consolidating Adani cement platform — a roll-up of Indian cement assets under one roof.
New Leadership and One Platform
In 2026, Managing Director Ajay Kapur retired, and Vinod Bahety took over as CEO as the company reorganized its leadership. The parent announced it would merge ACC and other cement businesses into Ambuja, creating a single unified "One Cement Platform" instead of a set of separately listed companies.
The 155 Million Tonne Plan
With the platform assembled, Ambuja announced a 14,500 crore rupee expansion plan to reach 155 million tonnes of capacity by fiscal 2030. It was starting from 113.5 million tonnes, with 119 million expected by early 2027, and the plan called for new grinding and clinker plants across six states in fast-growing markets. In four decades the company had gone from one planned plant to a national building machine.
