Tata Trusts, the majority shareholder of Tata Sons Pvt., has proposed merging the holding company with two of its unlisted subsidiaries in an effort to avoid a mandatory public listing. The plan, disclosed on Wednesday, involves folding Tata Electronics Systems Solutions Pvt. and Tata Consulting Engineers into Tata Sons, transforming it into a combined holding-operating entity that would not fall under listing requirements.

The proposal, which still requires a no-objection certificate from the Reserve Bank of India (RBI) as well as approval from the Tata Sons board, comes amid ongoing tensions between Noel Tata, who leads the charities that own 66% of Tata Sons, and Natarajan Chandrasekaran, chairman of Tata Sons. The dispute recently escalated during a contentious board meeting on September 17, when the board reappointed Chandrasekaran despite objections from Noel Tata, and moved forward with plans to prepare for a public listing of the holding company.

This confrontation between the RBI-classified “Upper Layer Non-Bank Finance Company” and its largest shareholder puts the future governance of the Tata Group—the Indian conglomerate with annual revenues exceeding $185 billion—at risk. The standoff raises concerns about potential instability among the more than two dozen listed companies controlled by the group. It also threatens to impact key initiatives aligned with Prime Minister Narendra Modi’s ambitions to develop advanced technology capabilities in India.

Tata Trusts stated it has shared the merger idea with the RBI but provided no further details on regulatory feedback. The strategy hinges particularly on including Tata Electronics Systems Solutions Pvt., a rapidly growing unit that manufactures products including iPhones for Apple Inc., in hopes of qualifying Tata Sons as an operating company rather than a holding company subject to mandatory stock market listing.

The outcome of this dispute will be closely watched, as it shapes the governance structure and regulatory compliance of one of India’s largest and most influential business groups.
