Sebi has given exemption from open offer requirements with respect to the six lenders through six separate but similarly-worded orders.
According to the regulator, there would be no change in control of the banks pursuant to the proposed acquisition of additional shares by the government.
"Further, there will be no change in the number of equity shares held in the target company by the public shareholders, pursuant to the proposed transactions," Sebi said in the order regarding Punjab National Bank.
According to the orders, the infusion of additional capital by the government is stated to enable the six banks to meet regulatory capital norms. It would also provide them with additional leverage for raising further equity capital at a later date as and when the need arises, the regulator said.
Pursuant to the capital infusion, the government's stake would rise by 5.21 per cent in Punjab National Bank, 6.25 per cent in Canara Bank and 9.73 per cent in Syndicate Bank.
In the case of Vijaya Bank, the shareholding would go up by 5.48 per cent while it would be additional stakes of 5.33 per cent and 11.91 per cent in Bank of Baroda and Union Bank of India, respectively.
The acquisition is on preferential allotment basis for the financial year 2017-18.
In February, the six lenders had filed separate applications on behalf of Indian government seeking exemption from the applicability of Regulation 3(2) of the SAST (Substantial Acquisition of Shares and Takeovers) Regulations.
Regulation 3(2) requires an acquirer to making a public announcement of an open offer for acquiring shares in case the existing stake goes beyond a certain threshold.
In January this year, the government had proposed infusion to the tune of Rs 54.73 billion in Punjab National Bank, Rs 48.65 billion in Canara Bank and Rs 28.39 billion in Syndicate Bank.
Besides, capital infusions of Rs 12.77 billion in Vijaya Bank, Rs 53.75 billion in Bank of Baroda and Rs 45.24 billion in Union Bank of India were proposed.
