High-profile restaurateur Sanjay Narang is all set to board the initial public offering (IPO) bus.If successful, the public issue of shares by Mars Restaurants Pvt Ltd will be the first-ever IPO by any Indian restaurant chain. Mars will be tapping the stock markets to raise funds for its expansion plans.The Rs 24-crore company plans to issue 55,00,000 shares of Rs 10 each which will constitute 52.42 per cent of the fully diluted post issue paid-up capital of the company. Promoter Narang’s stake will fall to 35 per cent after the IPO hits the markets.But the company has not decided on the timing as the stock market regulator Securities and Exchange Board of India (Sebi) is yet to clear the issue. Interestingly, the company — which operates 16 outlets — has an accumulated loss of Rs 2.55 crore for the fiscal ended March 2004.Analysts say it will be tough for the company to convince investors to put their money in a company whose business model has high failure record. Mars itself has closed 10 restaurants in Mumbai as they were unviable. ‘‘It looks like the issue is very small and the company requires money to meet its fund requirements,’’ says BSE broker Venkatesh Aiyer. ‘‘Its huge losses could be a dampner and risky for investors.’’The IPO will be funding Narang’s expansion project to open more food courts across the country.
