Inside the Ambuja–ACC–Orient Merger

Ambuja Cements’ board has approved a major consolidation that will merge ACC Ltd and Orient Cement Ltd into Ambuja, creating a single pan-India cement platform under the Adani Group. The board approved two separate schemes of amalgamation on December 22, 2025; the transaction is subject to statutory and shareholder approvals and is expected to be completed within about a year.

The Mechanics: How Shareholders Will Swap

The company’s official release sets out precise share-exchange ratios. For every 100 equity shares of ACC (face value ₹10 each), Ambuja will issue 328 equity shares of Ambuja (face value ₹2 each). For every 100 equity shares of Orient Cement (face value Re.1 each), Ambuja will issue 33 equity shares of Ambuja (face value ₹2 each). These ratios determine the relative ownership that ACC and Orient shareholders will hold in the enlarged Ambuja.

Why the Deal Now: Scale, Simplification and Cost Savings

Adani’s stated the rationale is straightforward: simplify the corporate structure, unify brands and networks, and extract operating synergies from pooled manufacturing and logistics. Management expects to save at least ₹100 per tonne through optimisation of manufacturing sites, distribution networks, sales and marketing spends, and other overheads, a material benefit in a business where margins per tonne matter. Ambuja says the consolidation will also strengthen the balance sheet and support planned capacity expansion.

Ambuja has also highlighted an ambition to increase cement production capacity from 107 million tonnes per annum (MTPA) to 155 MTPA by FY28.

Market Reaction and Investor Takeaways

Markets reacted quickly. Orient Cement shares surged after the announcement, reflecting the premium implicit in the swap for smaller listed peers; some trading desks reported rallies of around 9–10% for Orient. Ambuja’s stock also moved higher (reports cited a gain of about 4% at one stage), while ACC’s market response was more muted, and the share price fell by 1.21% on the National Stock Exchange because ACC shareholders receive a comparatively larger number of Ambuja shares, which can dilute earnings per share for existing Ambuja holders in the short term.

Timetable, Approvals and Advisers

Ambuja says the schemes will move through the usual regulatory and shareholder approval steps, including National Company Law Tribunal (NCLT) hearings and SEBI/stock-exchange filings where applicable; the company expects the full process to take up to a year. Independent joint valuers and fairness opinion providers have been engaged—GT Valuation Advisors and BDO Valuation Advisory as joint valuers, and IDBI Capital and SBI Capital Markets as fairness opinion providers. Legal counsel includes Cyril Amarchand Mangaldas and Singhi & Co.

Risks and What to Watch Next

While the company sees the merger as a profitable venture, there are multiple integration risks that should not be overlooked. Common hurdles include aligning plant footprints, rationalising routes to market, and merging workforces and IT systems. Realisation of the ₹100 per tonne synergy is an estimate and will depend on execution, commodity prices such as fuel, pet coke, and shipping, and demand trends in construction.

Regulators will also scrutinise the scheme for minority shareholder protections and valuation fairness.

Investors should watch forthcoming scheme documents, NCLT hearings, and detailed financial models from brokerages that quantify EPS and balance-sheet impacts.
