Diamines & Chemicals Limited has issued an important notice to shareholders regarding regulatory compliance and investor protection initiatives. The company has published newspaper advertisements in Business Standard (English) and Vadodara Samachar (Gujarati) to inform stakeholders about two significant developments.

Special Window for Physical Share Transfers

In compliance with SEBI circular no. HO/38/11(12) 2026-MIRSD-POD/I/3750/2026 dated January 30, 2026, the company has opened another special window for transfer and dematerialization of physical securities. This initiative specifically targets securities that were sold or purchased prior to April 1, 2019.

The special window also accommodates transfer requests that were previously rejected, returned, or unattended due to document deficiencies or procedural issues. Shareholders must submit their transfer requests along with requisite documents to the company's Registrar and Share Transfer Agent (RTA).

Registrar and Transfer Agent Details

Shareholders can submit their documents to MUFG Intime India Private Limited at the following address:

• Location: "Geetakunj" 1, Bhakti Nagar Society, Behind ABS Tower, Old Padra Road, Vadodara - 390015
• Phone: 0265-3566768
• Email: vadodara@in.mpsm.mufg.com

Second 100-Day Saksham Niveshak Campaign

Following the Investor Education and Protection Fund Authority (IEPFA) directive dated March 27, 2026, the company has initiated the second 100-day "Saksham Niveshak" campaign.

Campaign Objectives and Benefits

The Saksham Niveshak campaign aims to help shareholders who have not claimed their dividends or updated their KYC and nomination details. The proactive initiative specifically reaches out to shareholders to:

• Update KYC details including PAN, email address, and contact numbers
• Refresh bank mandates and nomination information
• Claim unpaid or unclaimed dividends
• Prevent transfer of shares and dividend amounts to IEPF

Important Compliance Notes

Shareholders should note several critical compliance requirements. Securities re-lodged for transfer will be credited to the transferee only in demat mode and remain under lock-in for one year from the registration date. During this lock-in period, such securities cannot be transferred, lien-marked, or pledged.

Transfer requests submitted after February 4, 2027, will not be accepted by the company or RTA. The company emphasizes that both initiatives are designed to protect shareholder interests and ensure regulatory compliance while providing adequate time for necessary documentation and procedural completion.

The notice was signed by Company Secretary Hemaxi Pawar (Membership No.: A52581) and digitally authenticated on April 16, 2026, demonstrating the company's commitment to transparent communication with its stakeholders.
