This is a regulatory disclosure made by Hindusthan Insulators & Industries Limited to the BSE Limited, intimating them about the issuance of a second reminder letter to shareholders for the dematerialization of physically held shares.

The action is undertaken pursuant to SEBI Gazette Notification no. SEBI/HO/MIRSD/MIRSD_RTAMB/P/CIR/2022/8 dated January 25, 2022. The company's Registrar and Transfer Agent (RTA), Skyline Financial Services Pvt. Ltd, is handling the communication with shareholders.

A 'Letter of Confirmation' was first issued to all relevant shareholders on March 20, 2026. This letter is valid for a period of 120 days from its date of issuance, within which a shareholder must submit a dematerialization request to their Depository Participant.

The RTA issued a first reminder letter on May 06, 2026, after 45 days had elapsed from the issuance of the initial Letter of Confirmation. This filing concerns the issuance of a second reminder letter on June 18, 2026, as 90 days have now elapsed without the company receiving the dematerialization request from the shareholder example provided, Nutan Prashant Parekh (Folio No. 1682).

The disclosure explicitly states that after the expiry of the 120-day period (from March 20, 2026), requests for dematerialization will not be entertained. As per SEBI operating guidelines, the physical shares for which no demat request is received will be transferred to a Suspense Escrow Demat Account of the company.

The financial impact of this procedural action is not quantified in the disclosure.
