In this regard, we wish to inform you that, following a comprehensive review of the Company’s evolving business environment and overall manufacturing strategy, the Board has reconsidered the proposal and decided to pursue an alternative approach to the proposed setting up of the manufacturing facility. Accordingly, instead of the Company setting up and funding the new manufacturing facility directly, the facility will now be set up by Borosil Scientific Limited (“BSL”) at Bharuch, Gujarat, with the capital expenditure for the facility to be incurred by BSL, subject to the requisite approvals. The Company’s long-term requirements for the relevant glassware products will continue to be supported through the existing manufacturing arrangement between the Company and BSL. The Company remains committed to pursuing its growth plans, expanding its market presence and strengthening its position across its key glassware categories, in alignment with its strategic priorities. This intimation is also available on the Company’s website at www.borosil.com. Thanking you. Yours faithfully, For Borosil Limited Pradeep Joshi Company Secretary & Compliance Officer FCS - 4959
