We wish to inform you that the work on the third double-wall line is currently in progress, and the commencement of commercial production from the said line is now expected by January 2027. The revised timeline is primarily attributable to certain logistical and supply- chain constraints in the receipt of imported equipment from China, coupled with the scheduling and availability of the supplier’s technical personnel for installation and commissioning. The Company is closely coordinating with the supplier to expedite the balance activities relating to installation and commissioning and is taking necessary steps to ensure completion of the pending activities in line with the revised timeline. This is for your information and record, please. This intimation is also being uploaded on the Company's website at www.borosil.com. Thank you. Yours faithfully, For Borosil Limited Pradeep Joshi Company Secretary & Compliance Officer FCS – 4959
