Coal India 2026: SECL, MCL stake sale plans cleared

Key development at the March 23 board meeting

Coal India Limited (CIL) has granted in-principle approval to partially divest stakes in two key subsidiaries, South Eastern Coalfields Limited (SECL) and Mahanadi Coalfields Limited (MCL). The decisions were taken at the CIL board meeting held on March 23, 2026, and disclosed through filings to the stock exchanges. The moves are positioned as part of Coal India’s broader push to list subsidiaries and deepen capital market participation. In SECL’s case, the plan combines a secondary sale by Coal India with a fresh issuance of shares by the subsidiary. For MCL, the company has approved a stake sale from Coal India’s existing holding, with listing routes that can include IPO-related mechanisms. The proposals are to be executed in the domestic market and can be carried out in one or more tranches.

What Coal India approved for South Eastern Coalfields (SECL)

For SECL, Coal India’s board approved divestment of up to 25% of the equity shares held by CIL through an Offer for Sale (OFS). Alongside the OFS, SECL may issue fresh equity shares aggregating up to 10% of SECL’s post-issue paid-up equity share capital. Coal India stated that this combined divestment and fresh issue would aggregate up to 35% of SECL’s post-issue paid-up equity capital. The company indicated that the transaction may be executed in one or more tranches. The stated routes include an Initial Public Offer (IPO) and/or other permissible market routes in the domestic market. SECL was described as among the highest coal-producing subsidiary companies of Coal India.

What Coal India approved for Mahanadi Coalfields (MCL)

In a separate filing, Coal India said its board granted in-principle approval for divesting up to 25% of its equity stake in MCL. MCL is currently a wholly owned subsidiary, as referenced in the provided information. The proposed divestment is expected to be executed through an OFS mechanism in one or more tranches. Coal India also noted that the divestment will be executed via IPO or other permissible market routes in the domestic market, reflecting flexibility on the final structure. The plan builds on earlier steps taken toward MCL’s listing, and is framed as part of value unlocking and improving market participation.

OFS, fresh issue, and tranches: how the structure works

The SECL proposal has two components: a sale by the parent (OFS) and a fresh issue by the subsidiary. An OFS typically involves an existing shareholder selling shares to public investors, while a fresh issue increases the company’s outstanding shares by issuing new equity. Coal India’s filing specifically references an OFS for up to 25% in SECL, plus a fresh issuance of up to 10% by SECL. For MCL, the proposal is a divestment of up to 25% via OFS, with listing to be executed via IPO and/or other permissible routes. In both cases, the company has kept room to execute the transactions in multiple tranches, which links timing to market conditions and readiness.

Roadmap context: earlier approvals in December 2025

Coal India had previously authorised the separate listings of both subsidiaries through distinct resolutions in December 2025. The article text also refers to an earlier in-principle approval to list MCL, indicating a phased approach rather than a single-step transaction. This sequencing matters because it signals that the March 2026 decision is an advancement of a pre-announced listing roadmap, rather than a standalone announcement. The latest approvals focus on the specific stake-sale and issuance structure that could be used for eventual public market participation. While the board approvals are in-principle, the company has clearly outlined the range of permissible mechanisms. The execution timeline, however, is dependent on subsequent approvals and conditions.

Approvals and next steps: Ministry of Coal, DIPAM, regulators

Coal India indicated that the proposal will be forwarded to the Ministry of Coal for further submission to DIPAM. Final implementation is contingent on regulatory approvals and government authorisations. The process will involve coordination with the Ministry of Coal and other relevant authorities, as stated in the provided text. The company also noted that the proposed transaction remains subject to necessary approvals and the completion of required formalities. As a result, the actual timing of an OFS or IPO-led process is not fixed at this stage. Coal India also referenced compliance with regulatory frameworks as part of its approach.

Market reaction: Coal India stock falls after the announcement

Following the announcement of the in-principle approvals, Coal India shares declined. As of March 24, 2026, at 10:25 AM, the stock was trading at ₹440.80 per share, down 3.17% from the previous closing price, according to the included update. Separately, the stock was also reported to have fallen nearly 4% on Tuesday, March 24, hitting an intraday low of ₹439 on the NSE. The decline came after the board approved the partial disinvestment and listing plans for SECL and MCL. The coverage also noted the move followed a surge in previous sessions, though no specific percentage for prior gains was provided.

Why the listing push matters for investors

Coal India has described the effort as part of a broader initiative to monetise subsidiary assets while strengthening its capital market presence. The text also links the listing approach to improving transparency and operational benchmarking for subsidiaries in public markets. For investors, the key data points are the approved stake-sale limits and the combination of OFS and fresh issue contemplated for SECL. The structure also indicates that Coal India is keeping options open on the exact route, including IPO-linked mechanisms, rather than committing to a single format immediately. At this stage, the information is limited to in-principle approvals and process routing. Any valuation, pricing, or issue size beyond the percentage limits has not been disclosed in the provided material.

Conclusion

Coal India’s board has approved in-principle plans to divest stakes in SECL and MCL, with SECL’s proposal combining up to 25% OFS and up to 10% fresh issue, and MCL’s proposal allowing up to 25% divestment via OFS with IPO-linked routes. The proposals will be forwarded to the Ministry of Coal for submission to DIPAM, and final execution depends on regulatory and government approvals, along with market conditions. Investors will likely track subsequent filings for clarity on transaction structure, tranching decisions, and regulatory progress.
