AI summary

ACC Limited board has approved amalgamation with parent Ambuja Cements, both Adani group cement firms. Share swap: 328 Ambuja shares (Rs 2 FV) for every 100 ACC shares (Rs 10 FV). No cash deal. ACC ceases to be a separate listed entity; Ambuja, which already holds 50.05% of ACC, is the surviving company. Subject to stock exchange NOC and NCLT approval. Rationale: manufacturing synergies, cost efficiencies, unified structure. Independent valuers and fairness opinion obtained.

Likely market impact

ACC shareholders other than Ambuja get 3.28 Ambuja shares per ACC share. ACC to delist post-merger; deal awaits NCLT and SEBI approvals.
