(Bloomberg) -- Interloop Ltd., which makes socks for Nike and Adidas, is planning Pakistan’s biggest ever initial public offering by a private firm.

The company plans to raise as much as 6.8 billion rupees ($51 million) to expand its sock manufacturing capacity by around 20 percent and enter the denim business, said Chairman and Co-Founder Musadaq Zulqarnain. It will offer 12.5 percent of the business in the sale, likely to take place in January, and is aiming to lift revenue by 77 percent over five years, he said.

“Our capacity is already full,” Zulqarnain said in an interview at the company’s head office in Faisalabad. Interloop can see more growth, so will “take that risk” to expand, he said.

The listing comes as Prime Minister Imran Khan tries so spark an export revival to make up ground that Pakistan has lost to low-cost manufacturing destinations like Vietnam and Bangladesh. The new government has announced plans to cut gas and electricity prices to support companies selling abroad, although the push has been criticized for relying too much on subsidies.

The Interloop offer will surpass the previous record for a private company, when Pakistan Stock Exchange Ltd. raised 4.5 billion rupees two years ago. There have been larger sales by state-controlled companies in Pakistan.

Interloop was founded in the early 1990s by Zulqarnain and his brother, Chief Executive Officer Navid Fazil. The company now employs around 16,000 people and makes more than half a billion pairs of socks a year. Revenue for the 12 months through June was 31 billion rupees, according to Zulqarnain.

“They are one of the most well-managed companies in Pakistan, so they should not have a problem with demand,” said Amjad Waheed, chief executive officer at NBP Fund Management Ltd. in Karachi. “Investors are sitting with cash on the sidelines after the market drop over the past year.”
