"The file document for rights issue is ready. We will soon approach the SEBI," a senior company official said.
In February, the company's board had given in-principle approval for issuing shares to existing shareholders through the rights issue to raise Rs 725.4 crore.
Under a rights issue, stocks are issued to existing investors of an entity as per their holding at pre-determined price and ratio.
Early last month, Shree Renuka Sugars had issued open offer but it failed because the market price was much higher than the open offer rate of Rs 21.89 per share.
The company had to go for a mandatory open offer after it announced sale of 27 per cent stake in Shree Renuka Sugars to Singapore-based agri-business major Wilmar International for Rs 517 crore through a preferential allotment of fresh equity.
In the open offer, issued by both Wilmar and existing promoters proposed to acquire 24.31 crore shares at Rs 21.89 per share, representing 26 per cent stake.
But the joint-venture partners were able to acquire only 1,750 shares worth Rs 38,307 as the open offer rate was much lower than the market price of around Rs 28-29 per share.
Post open offer, the combined stake of Shree Renuka Sugars and Wilmar stands at little over 55 per cent in the company with both partners having an equal stake.
Renuka Sugars operates 11 sugar mills in India and Brazil with a total crushing capacity of 20.7 million tonne per annum and two port-based refineries with sugar production capacity of 1.7 million tonnes per year.
Wilmar's business activities include oil palm cultivation, oilseeds crushing, edible oils refining, sugar milling and refining, speciality fats, biodiesel and fertilisers manufacturing and grains processing.
