Hindustan Zinc saw a reduction in promoter encumbrance after Vedanta Limited released 5,15,64,666 equity shares from pledge on September 18, 2026.

The release was disclosed by SBICAP Trustee Company Limited, acting as the security trustee for the lenders. The shares were originally pledged by Vedanta to secure facilities granted by lenders. This action reduces the total encumbered holding of Vedanta in the zinc major.

Details of Share Release

The disclosure was made under Regulation 29(2) of the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011. The transaction involved the release of shares carrying voting rights, which were previously held as encumbrance by SBICAP Trustee Company Limited.

Composition of Remaining Encumbrance

Following the release, the remaining encumbrance consists primarily of Non-Disposal Undertakings (NDU). The breakdown of the remaining 1,15,01,47,609 shares is as follows:

• Pledged Shares: 5,15,64,669 equity shares (remaining after partial release)
• Non-Disposal Undertaking: 1,09,85,82,940 equity shares

The NDU component accounts for 26.00% of the paid-up share capital, while the remaining pledged portion constitutes approximately 1.22%.

What the Numbers Show

The data reveals a significant structural shift in how Vedanta’s stake in Hindustan Zinc is secured. While the total encumbrance dropped by 1.22%, the composition changed notably. Prior to this release, the encumbrance was split between 2.44% in pledges and 26.00% in NDUs. Post-release, the pledge component has been reduced to 1.22%, while the NDU remains unchanged at 26.00%. This indicates that the primary security mechanism for the lenders remains the Non-Disposal Undertaking rather than traditional share pledges, suggesting a long-term hold strategy for the majority of the stake.
