Adani Properties has acquired the shares from Mauritius based Bid Services Division and ACSA Global Ltd.
As per the combination notice filed with CCI, the transaction involves acquisition of shares through two separate share purchase agreements.
While Adani is buying 13.5 per cent stake in Mumbai International Airport from Bid Services Division, the rest 10 per cent has been acquired from ACSA, as per the notice said.
In a separate tweet, Competition Commission of India (CCI) said it "approves merger of the BNP Paribas Mutual Fund and the Baroda Mutual Fund".
Bank of Baroda and BNP Paribas Asset Management in a joint statement in October had said they entered into binding agreements.
The strategic alliance would allow both companies to leverage each other's strengths to offer products specially designed for retail and institutional clients in India, they had said.
Baroda Asset Management is a wholly-owned subsidiary of Bank of Baroda, while BNP Paribas Asset Management India is an entity of BNP Paribas Asset Management Asia.
The regulator has also given nod to "secondary acquisition of additional 3.28 per cent of the issued and paid up share capital of Delhivery Private Limited by SVF Doorbell (Cayman) Ltd".
In February 2019, CCI had approved SVFD's subscription to compulsorily convertible preference shares amounting to 22.44 per cent of the total shareholding of DPL (Delhivery Pvt Ltd) on a fully diluted basis.
"Accordingly, subsequent to the investment, SVFD will hold up to approximately 25.72 per cent the issued and paid up share capital of DPL on a fully diluted basis," CCI said.
Further, in another tweet, the regulator approved "subscription to securities of Ecom Express Private Limited by CDC Group plc".
CDC is a development finance institution, wholly owned by the UK government, which provides scarce and patient capital to private sector entrepreneurs in developing countries, the combination notice said.
Besides, Ecom Express is engaged in third party logistics services including delivery services and e-KYC facilitation for the customers of banks, NBFCs and other companies that require such services among others, it added. SRS BAL
