We request you to inform the members of the exchange accordingly. Thank you, Yours faithfully For Atul Limited Lalit Patni Company Secretary and Chief Compliance Officer Encl: as above Press release Clarification on treated effluent discharge from Atul site Atul, October 16, 2026: It has come to the notice of the Company that certain incorrect information and videos concerning the discharge of effluent from Atul site into the Par river are being circulated. The Company uses an approximately 4-km long pipeline, laid entirely within the estuary, to discharge treated effluent into the estuarine zone. Considering the age of the existing pipeline and the need to mitigate potential environmental risks, the Company had proactively initiated the installation of a new pipeline. The necessary approvals have been obtained from the relevant authorities and the work is at an advanced stage. During the period, accidental damage was identified in the existing pipeline at a location approximately 1 km from the effluent treatment plant of the Company, within the estuary. This resulted in the inadvertent release of treated effluent into the estuarine zone for a short period, until the damage was detected. The treated effluent released during this period complied with the prescribed standards of the Gujarat Pollution Control Board. Immediately upon detecting the damage, the Company isolated the affected section of the pipeline and voluntarily suspended effluent discharge through it as a precautionary measure. The necessary repair work has been initiated, and a competent agency has been engaged to undertake the required repairs at the earliest. Discharge through the affected pipeline will remain suspended until the repairs are completed and the pipeline is inspected and confirmed fit for safe operation. The Company does not expect any material impact due this incident. The Company reaffirms its commitment to environmental protection and to complying with all applicable environmental laws, rules and regulatory requirements.
