Jersey Mike’s Subs saw a decline in its stock price on its first day of trading on the New York Stock Exchange Thursday, following its initial public offering (IPO) Wednesday. The company priced approximately 43.5 million shares at $23 each, but the stock closed down 6% at $21.63.

The restaurant chain’s IPO is among the most notable this year, launching with a market valuation nearing $8 billion. This milestone comes just 18 months after private-equity firm Blackstone acquired a majority stake in the sandwich company. Through the offering, Jersey Mike’s raised around $1 billion.

Founded over 70 years ago, Jersey Mike’s has expanded to more than 3,000 locations across the United States. Despite going public, Blackstone will maintain majority control of the company, retaining the majority of voting power. Following the IPO, shareholders will hold approximately 13.7% of the voting rights.

The offering reflects Jersey Mike’s strategy to leverage its established brand and loyal customer base as it moves into the public market, while Blackstone continues to oversee the company’s operations and growth trajectory.
