Ambuja Cements merger: NCLT timeline, swap ratios 2026

What Ambuja Cements has proposed

Ambuja Cements Limited, part of the Adani Group, has moved to consolidate key cement assets under a single listed entity. The company’s board approved two separate Schemes of Amalgamation to merge ACC Limited and Orient Cement Limited into Ambuja Cements, creating what it described as a consolidated “One Cement Platform”. The approvals were taken at the board meeting held on December 22, 2025.

The consolidation is structured as mergers into Ambuja Cements, rather than a cash acquisition. The schemes are subject to statutory and shareholder approvals, and the company has indicated the overall process could take up to about a year, depending on regulatory steps.

Board approvals and the “One Cement Platform” plan

The board approvals on December 22, 2025 set the formal process in motion for merging both ACC and Orient Cement with and into Ambuja Cements. The stated objective is to streamline operations and unlock synergies through a single pan-India cement platform.

Alongside the merger plan, the available disclosures also reference that the transaction will move through the normal regulatory pathway, including filings with stock exchanges and the involvement of the National Company Law Tribunal (NCLT) where applicable. The merger has been proposed under Sections 230 to 232 of the Companies Act, 2013, and the disclosures were made to NSE and BSE.

NCLT milestone for ACC-Ambuja shareholder approvals

A key regulatory milestone came from the National Company Law Tribunal, Ahmedabad Bench. On July 29, 2026, the NCLT directed ACC Limited and Ambuja Cements Limited to convene separate equity shareholder meetings on September 29, 2026 to approve the proposed Scheme of Amalgamation.

The order also notes that meetings of unsecured creditors were dispensed with because no compromise is offered. This direction is part of the formal court-led process required for schemes under the Companies Act.

Key dates investors should track

The NCLT process includes defined dates for shareholder participation and notice timelines. The cut-off date for determining eligibility to vote has been set as September 22, 2026. The record date mentioned for dispatch of notices is August 14, 2026.

These dates matter because they determine which shareholders can participate in voting and how the procedural steps for the meeting are carried out. The shareholder meetings on September 29, 2026 are a central step toward completing the scheme, subject to the remaining approval process.

Appointed Date and what “effective” means in the scheme

The ACC scheme envisages merging ACC Limited with and into Ambuja Cements Limited as a going concern. The Appointed Date specified is January 1, 2026. Upon the scheme becoming effective, ACC Limited would be dissolved without winding up, and Ambuja would issue new equity shares to ACC shareholders as per the share exchange ratio.

An appointed date is part of the legal structure of a scheme. It is used to define the point from which the merger is treated as effective for the purposes of the arrangement, once the scheme receives the required approvals.

Share swap ratios: ACC and Orient Cement

Ambuja’s official release sets out the exchange ratios that will apply for eligible shareholders. For ACC shareholders, the swap is based on ACC’s face value of ₹10 per share, while Ambuja’s shares in the scheme have a face value of ₹2 each. For Orient Cement shareholders, Orient’s face value is Re. 1 per share, and the Ambuja shares issued would also be ₹2 face value.

The disclosures also specify that the deal does not involve any cash payments, reflecting a pure share-swap structure for the ACC merger as described in the filings.

Timeline of the consolidation process

The consolidation has progressed through multiple steps across 2025 and 2026, including separate schemes and tribunal directions.

Related tribunal approval: Sanghi Industries scheme

Separately, Ambuja Cements has also disclosed that the Ahmedabad bench of the NCLT approved the merger scheme with its subsidiary Sanghi Industries. The NCLT order described the scheme as the amalgamation, by way of merger, of Sanghi Industries Ltd into Ambuja Cements Ltd with an Appointed Date of 01.04.2024.

Ambuja had earlier said in December 2024 that, after the merger of the two companies, it would issue 12 equity shares of face value ₹2 each for every 100 Sanghi Industries shares of face value ₹10 held by Sanghi shareholders.

Market impact: what is confirmed so far

From the disclosed terms, the most concrete market-relevant inputs are the exchange ratios, the scheduled shareholder-meeting date, and the scheme mechanics. The structure is share-based and, for the ACC merger, explicitly described as involving no cash payments. The NCLT’s direction to hold shareholder meetings indicates the scheme has advanced within the tribunal process.

Beyond that, the companies have positioned the merger as a step to streamline operations and unlock economies of scale. However, the disclosures provided do not quantify expected cost savings, capacity additions, or profit impact, so the financial effect cannot be stated beyond the procedural and structural details already announced.

Why this consolidation matters for shareholders

For shareholders, the merger terms translate into a defined share swap and a clear voting timeline. ACC shareholders will receive Ambuja equity as per the 328-for-100 ratio if the scheme becomes effective, and Orient Cement shareholders are set to receive Ambuja equity as per the 33-for-100 ratio under the Orient scheme.

The next immediate checkpoint is the equity shareholder meetings on September 29, 2026. The company has also indicated that, subject to requisite approvals, the broader consolidation process is expected to be completed over the next one year.

Conclusion

Ambuja Cements’ plan to merge ACC and Orient Cement into Ambuja has moved into an important procedural phase, with the NCLT directing shareholder meetings for September 29, 2026 and the company disclosing fixed share-swap ratios. The next steps are the shareholder votes and the remaining statutory and regulatory approvals, including the NCLT process, as the schemes move toward effectiveness.
