In a filing to the Bombay Stock Exchange, Satyam said post-acquisition of additional 19,86,58,498 shares in the subsequent preferential allotment, Tech Mahindra's stake in the company would go up to 50.42 per cent.

Tech Mahindra, which acquired a 31 per cent stake in Satyam Computer for about Rs 1,756 crore in April, had launched an open offer to buy up to 20 per cent at Rs 58 a share that received poor response from public shareholders.

Only 4,20,915 Satyam shares or 0.04 per cent stake were tendered in the offer as the offer price was 30 per cent below the prevailing market price at that time, thus necessitating the beleaguered IT firm to make a preferential allotment to Tech Mahindra.

Satyam, now rebranded as Mahindra Satyam, had received the Company Law Board's approval for allotment of an additional 19.86 crore shares at Rs 56 a piece on preferential basis, aggregating to Rs 1,112.48 crore, to its new owner.
