The shadow lender's last funding round in December 2021 was closed at a valuation of 220 billion Indian rupees, roughly $3 billion at the time.
Fidelity and India's HDFC Mutual Fund, among others, are in in talks with Five Star to invest in the so-called anchor book of the IPO but at a company valuation of 160 billion rupees, due to weak market sentiment, the sources said.
Five Star is planning to list in the last week of October, which coincides with Diwali, a popular Indian festival.
Two sources, however, said that the company was closely tracking the ongoing stock market weakness in India before finalising a date.
For the fiscal to March 2022, Five Star recorded a net profit of 4.5 billion Indian rupees ($55.14 million) on a total income of 12.5 billion Indian rupees ($152.74 million), growing about 20% year-on-year, according to its annual report.
