Internal debates regarding the corporate structure and possible public market listing of Tata Sons have resurfaced at the highest levels of the conglomerate. Darius Khambata, a senior advocate and prominent trustee at Tata Trusts, has decided against seeking another term. In a formal communication sent on November 2, 2026, addressed to Tata Trusts Chairman Noel Tata and Chief Executive Officer Siddharth Sharma, Khambata confirmed his departure while raising substantial reservations about how discussions with the Reserve Bank of India (RBI) have been managed. He noted that these regulatory deliberations have failed to clarify how Tata Sons can achieve listed-company transparency and institutional reporting benchmarks without actually floating its shares on the equity markets.
Independence and the Decision Against Term Extension
Khambata has been serving on the boards of both the Sir Dorabji Tata Trust (SDTT) and the Sir Ratan Tata Trust, with his formal tenure set to conclude on November 9, 2026. His letter revealed that both Noel Tata and Siddharth Sharma favored his continuation as trustee. However, securing a renewal required seeking formal concurrence from the remaining trustees. Khambata expressed that he was unwilling to compromise his personal independence by actively requesting consent from fellow board members for another term, choosing instead to conclude his tenure.
In the communication, Khambata emphasized that his duties as a trustee had consistently centered on independent judgment and safeguarding the institution's core mission. He recalled joining the trusts following a personal request from the late Ratan Tata, underscoring that the ethical principles established by Ratan Tata had continually steered his decision making throughout his time on the board.
Questions Over RBI Engagement and Disclosure Norms
A key focus of Khambata's correspondence was his dissatisfaction with the dialogue between Tata Sons and the central bank. He pointed out that the engagement did not satisfactorily demonstrate how the holding entity, even if it surrenders its core investment company (CIC) status or reorganizes its operating setup, would implement the rigorous transparency and reporting systems expected of listed corporations. His primary concern remains whether there is any valid structural pathway for Tata Sons to satisfy public disclosure obligations while remaining an unlisted private entity.
As the principal investment holding firm of the conglomerate, Tata Sons commands substantial ownership stakes across the group's major industrial and commercial enterprises. A public listing would open share ownership to institutional and retail investors, while obligating the company to disclose detailed financial results and operational matters to the public. Khambata has consistently maintained that such a transition could alter the ownership equilibrium of the conglomerate, previously categorizing the listing prospect as an existential question concerning the very foundation and autonomy of Tata Trusts.
Regulatory Mandates Under Upper Layer NBFC Framework
The regulatory friction originates from the updated oversight guidelines instituted by the Reserve Bank of India for non-banking financial companies (NBFCs). In October 2021, the RBI rolled out its scale-based regulatory architecture to address systemic exposure across the non-banking financial sector. Under this system, major entities that carry systemic scale and prominence are placed in the upper layer category, which imposes a mandatory requirement to list shares on public exchanges within a prescribed timeframe.
The central bank classified Tata Sons as an upper layer NBFC in September 2022, establishing an initial deadline of September 2025 for completing a market listing. Tata Sons sought to avert going public by clearing debt liabilities and initiating the surrender of its certificate of registration as a core investment company. Nevertheless, the banking regulator classified Tata Sons as an upper layer NBFC once more in August 2026, while indicating that the company's application to deregister remains under evaluation. That ongoing review has maintained regulatory pressure regarding the listing mandate.
Divergent Perspectives Within Tata Trusts
With Tata Trusts controlling approximately 66 percent of Tata Sons, the trust board holds considerable authority over the strategic direction of the parent company. Differing viewpoints on the listing question have created identifiable camps within the trusts. Leaders such as Noel Tata and Darius Khambata have consistently favored retaining Tata Sons as an unlisted private entity, contending that this setup protects the conglomerate's dedicated philanthropic model and shields long-term decision making from immediate market pressures.
Conversely, other trustees, including Venu Srinivasan and Vijay Singh, have previously expressed openness toward a public listing, viewing enhanced market disclosure and external scrutiny as avenues to strengthen corporate governance and accountability. In his letter, Khambata highlighted a board resolution passed on July 28, 2025. That decision unanimously affirmed the stance against listing Tata Sons and entrusted Tata Sons Chairman N Chandrasekaran with conducting ongoing dialogue with the banking regulator. Khambata's exit highlights the unresolved tensions surrounding this regulatory crossroads.
