In an informal guidance, SEBI has told the promoters of Adani Power (APL) that they can acquire additional shares in the company without triggering the open offer norm, as it is exempt according to an earlier scheme of arrangement. Adani Enterprises held 68.99 per cent stake in APL before May 22. Following an arrangement, the latter’s stake in Adani Power was transferred to the former’s promoters on proportionate basis.
