Sun Group may have finally finalised an investor for partially or completely offloading its stake in SpiceJet . Sources say talks are in the final stages and a term sheet may be signed by December. As per the talks with investors, SpiceJet is valued at Rs 1500 crore, which is double the company’s market cap. Sun Group and Kalanithi Maran together hold 53.4 percent stake in SpiceJet. It is not yet clear whether SpiceJet promoter and media baron Kalanithi Maran is mulling to exit completely from the low-cost airline. Earlier, the Marans were looking to sell 12-14 percent stake to bring in capital in a bid to bring down debt, which currently stands at Rs 1,486 crore. But currently they may be looking to sell their entire stake in the company. The company is exploring various options to further capitalize. SpiceJet reported a net loss of Rs 310 crore for the second quarter ended September 30, 2014. The airline had posted a net loss of Rs 559 crore in the corresponding quarter of the last financial year, the company said in a BSE filing. SpiceJet witnessed a 15 percent growth in total revenue in comparison to same quarter last year, the company said. Maran has been on the lookout for potential buyers to offload his stake in the loss-making airline. Kapil Kaul, south Asia chief executive of aviation consultancy Centre for Asia Pacific Aviation (Capa) has said that SpiceJet requires around USD 250 million as on March 2014 to bring books in order.
