OPG Power Ventures Plc

("OPG", the "Group" or the "Company")

Share Buyback Offer Deadline

OPG Power Ventures plc (AIM: OPG), a leading developer and operator of power generation assets in India, reminds Shareholders that following the passing of all resolutions at the Company's Annual General Meeting on 3 December 2025, the Share Buyback Offer remains open for acceptance by Qualifying Shareholders until 1.00 p.m. on 12 December 2025. The Share Buyback Offer Price is 6.27 pence per Ordinary Share and Qualifying Shareholders may tender some, all or none of their Ordinary Shares. 

The latest time and date for receipt of (i) Share Buyback Forms for certificated Ordinary Shares (together with share certificate(s) and/or other document(s) of title) and (ii) Transfer to Escrow ("TTE") Instructions for uncertificated Ordinary Shares, in relation to the Share Buyback Offer is 1.00 p.m. on 12 December 2025.

If Shareholders wish to continue holding Ordinary Shares in the Company, they do not need to take any action but should refer to the Circular in respect of the changes to the Company's Articles of Association and the implications of being a shareholder in a private company.

The Company will use the authority granted at the AGM to buy back up to 157.7 million Ordinary Shares.  The Family Concert Party is interested in 206,507,166 Ordinary Shares representing 51.53 per cent of the Company's issued share capital and has confirmed that it will not tender any of its respective Ordinary Shares pursuant to the Share Buyback Offer.

The resolutions passed at the AGM give the Company the authority to purchase up to 182 million Ordinary Shares.  However, the Board has resolved, as announced on 1 December 2025, to limit the Share Buyback Offer to up to 157.7 million Ordinary Shares, representing approximately 39.4 per cent. of the Existing Ordinary Shares.  The Board took this decision in order to address concerns regarding the potential concentration of ownership of the Company should the Share Buyback Offer be taken up in full. 

To the extent that tenders are received from Qualifying Shareholders by the Company in respect of less than 157.7 million Ordinary Shares then each Qualifying Shareholder who has validly tendered Ordinary Shares will have their tender accepted in full.

Announcement of the results of the Share Buyback Offer is expected on 15 December 2025.

Unless otherwise defined, capitalised terms in this announcement shall have the meaning set out in the Circular.
