The Adani Group in India recently approved a plan to consolidate its cement business, merging ACC Limited and Orient Cement Limited into Ambuja Cements to create a unified "One Cement" operating platform.

According to filings submitted to the stock exchange on December 22, 2025, the board of Ambuja Cements has approved the merger. This move is part of a series of measures by the group to streamline operations, eliminate overlapping corporate structures, and enhance competitiveness in the Indian cement market. The consolidation follows the group's acquisition of Holcim's Indian cement assets in 2022. The group expects the merger to generate synergies in areas such as production, manufacturing, logistics, sales, and marketing, leading to improved profit margins.

Karan Adani, Non-Executive Director of the Adani Group, stated that the merger will build a more resilient balance sheet, thereby supporting accelerated capacity expansion. Under the plan, the Ambuja and ACC brands will continue to be sold independently after the merger to preserve their respective brand values and eligibility for local incentive policies, while simplifying corporate governance and reporting structures. Analysts from JM Financial noted that the transaction will provide a premium for minority shareholders of Orient Cement and help improve business transparency.

The merger is expected to be completed within 12 months, subject to approval from shareholders and the National Company Law Tribunal of India. The effective date for ACC's merger is proposed to be January 1, 2026, while Orient Cement's merger will be retroactive to May 1, 2025.
