Vivo Bio Tech Limited has announced the expiry of 483 convertible equity warrants. These warrants, originally issued at Rs. 45 each to Antique Infotech Private Limited as part of a 26 lakh total issuance, were not exercised within their 18-month tenure. This development means the company will not realize the funds from these specific warrants, although it represents a very small portion of the total warrants issued.
