Dear Sir/Madam With reference to your e-mail dated 23rd June, 2026 bearing Ref. No. L/SURV/ONL/PV/GG/ 2026-2027 / 176, seeking clarification regarding the significant increase in the volume of trading in the Company's securities across the stock exchanges in the recent past, we wish to clarify that, the Company is in compliance with the provisions of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 ("SEBI LODR Regulations"), and has been promptly disseminating to the Stock Exchanges all material events, information, and disclosures that may have a bearing on the operations or performance of the Company, including all price-sensitive information, as and when required. We would like to further clarify that there is no undisclosed price-sensitive information, pending announcement, or corporate action that, in our opinion, requires disclosure to the Stock Exchanges at this point in time and that may have any bearing on the price or volume movement of the Company's securities. Accordingly, the increase in the trading volume of the Company's securities appears to be purely market- driven and attributable to prevailing market conditions. The Company has no control over, nor any specific knowledge of, the reasons for such market activity. We further assure you that the Company shall continue to comply with all applicable provisions of the SEBI LODR Regulations and will promptly disclose to the Stock Exchanges any material event, information, or development as and when required. We request you to kindly take the above clarification on record. Thanking You. For Clean Science and Technology Limited Ruchita Vij Company Secretary and Compliance Officer
