According to people familiar with the matter, Adani Group is in talks with a group of international lenders about obtaining an offshore loan of up to $750 million for its airport unit.

According to the people, lenders include Barclays Plc, First Abu Dhabi Bank PJSC, and Standard Chartered Bank Plc. They asked not to be identified because the information is not public. The proceeds would be used to fund capital expenditures and refinance dollar debt maturing in September. The unit intends to complete the debt raise by early May, they added.

Adani Airport Holdings Ltd. manages seven major airports in India and is preparing to open a new $2 billion international hub on the outskirts of Mumbai.

The loan will most likely be for less than five years, though the terms have yet to be finalized and may change, according to the people.

If successful, the borrowing would be Adani's second major offshore fund raise in less than a month. It is the latest sign that overseas lenders are becoming more comfortable lending to the conglomerate as the US Department of Justice conducts a bribery investigation into its billionaire founder, Gautam Adani.

Representatives from Barclays Plc and First Abu Dhabi Bank did not immediately respond.

Adani recently raised approximately $750 million through an offshore private placement bond. In that transaction, BlackRock Inc. purchased approximately one-third of the bonds issued to fund the acquisition of a construction firm.

In March, the state-owned Power Finance Corporation Ltd. refinanced an Adani Green construction loan worth $1 billion.
