Indian conglomerate Adani Group is reviving plans to seek about $1 billion through a US-listed dollar-denominated bond, according to people familiar with the matter, a move reflecting its intent to return to the US financing market as its legal troubles there ease . The ports-to-power group, controlled by billionaire Gautam Adani , has begun early-stage internal discussions and informal consultations with advisers, the people said, asking not to be identified because the deliberations are private. Any proceeds from the bond sale, carried out by its energy unit Adani Green Energy Ltd., would go toward capital expenditures and refinancing needs, they said.
