India's Adani Group said on Thursday it plans to sell a stake of up to 20% in Adani Wilmar to the public, as the conglomerate looks to comply with minimum public shareholding rules amid plans to exit the consumer goods company.

The Adani Group will raise 71.48 billion rupees ($833 million) by selling up to 20% stake in Mumbai-listed Adani Wilmar Ltd. as it exits non-core activities to focus on the bread-and-butter infrastructure businesses.

The OFS will have a base offer of 13.5% equity and a green shoe option for another 6.5% stake, a company filing said on January 9.

On January 9, the group had announced sale of 17.54 crore shares (13.50 percent equity) in the company on January 10 (to non-retail investors) and on January 13 (to retail investors) at a floor or minimum price of Rs 275 apiece.

The Adani Group will sell its stake in consumer goods firm Adani Wilmar to joint venture partner Wilmar International for 123.14 billion rupees ($1.44 billion) as the Indian conglomerate sharpens its focus on infrastructure projects.

Last month, the conglomerate had said that it will sell its entire 44 per cent stake in Adani Wilmar in a two-step process for $2 billion

Adani Group on Friday raised Rs 4,850 crore from the sale of 13.5 per cent of its stake in Fortune oil maker Adani Wilmar as part of a strategy to exit non-core activities to focus on main infrastructure business.

India's Adani Wilmar fell over 6% in early trade on Tuesday, a day after the Adani Group said it would sell its entire 44% stake in the consumer goods company in a $2 billion deal to focus on strengthening its infrastructure businesses.

The Offer for Sale (OFS) included an option to sell an additional 8.44 crore shares, equivalent to 6.50percent equity.
