3B BlackBio Dx Limited has submitted its annual regulatory disclosure to BSE Limited, confirming that its promoter group maintained clean shareholding throughout the financial year ended March 31, 2026. The disclosure, filed under SEBI Takeover Regulations, demonstrates the company's commitment to regulatory compliance and transparency.

Regulatory Compliance Declaration

The disclosure was filed by Nikhil Kuber Dubey, a key promoter of the company, who submitted the declaration on behalf of the entire promoter and promoter group along with persons acting in concert. Company Secretary and Compliance Officer Navneet Kaur (ACS No.29130) facilitated the filing to BSE Limited on April 4, 2026.

Share Encumbrance Status

The promoter group has declared that no encumbrance or pledge of shares was made directly or indirectly during the financial year ended March 31, 2026. This declaration covers all members of the promoter and promoter group, including persons acting in concert with the company.

The clean shareholding status indicates that promoters have maintained full ownership rights over their shareholding without creating any security interests or pledges against their equity stakes. This transparency measure is mandated under SEBI regulations to protect investor interests and maintain market integrity.

Corporate Governance Framework

The filing represents part of the company's ongoing compliance with SEBI's substantial acquisition and takeover regulations. These annual disclosures ensure that stakeholders remain informed about any changes in promoter shareholding patterns and encumbrance status.

The company operates from its registered office at 7C, Industrial Area, Govindpura, Bhopal-462023, and the disclosure has been copied to the Chairman of the Audit Committee as part of internal governance protocols. This filing reinforces the company's commitment to maintaining transparent corporate governance standards and regulatory compliance.
