Singh, to whom current promoters Maran family has agreed to transfer 'ownership, management and control' in the airline, said necessary downsizing will also be undertaken as part of the restructuring plan, but it would be kept at minimum.
At the end of July-September quarter of 2014, for which the latest shareholding pattern is available, Marans held 53.48 per cent stake in Spicejet. Thereafter, their stake rose further to 58.46 per cent pursuant to conversion of warrants.
While Singh did not disclose the names of the foreign investors he was talking to, sources said that they could include US-based JPMorgan.
"The airline has given a revival and restructuring plan to the Civil Aviation Ministry for change in control, which has to be cleared by it. Once they (the Ministry) do it, we will execute the revival plan," Singh told PTI.
Singh said the revival plan would focus on strengthening finances and operational efficiency, among others.
He has also drawn up a five-year plan to rejuvenate the low-cost carrier, which may include phasing out of the Bombardier Q400 fleet.
The original founder has re-boarded SpiceJet amid the carrier facing financial crunch and even curtailing its operations significantly.
In the quarter ended September 30, 2014, SpiceJet reported Rs 310 crore loss, widening from Rs 124 crore in the previous quarter. The losses were, however, lower in the year-ago quarter ended September 30, 2013 at Rs 560 crore.
In response to a query on whether the revival plan also includes some retrenchment, Singh said: "Downsizing has to be done... We will try to keep it at minimum."
SpiceJet has around 5,000 employees.
According to sources, the overall the deal size could be worth Rs 1,500 crore in three tranches.
