Krispy Kreme’s public stock debut is generating some pretty sweet news on the Nasdaq market despite low expectations.

The doughnut chain, which began trading under the DNUT symbol on Thursday, had priced its initial public offering at $17 per share, hoping to raise about $500 million. At the close, shares were trading at $21.

Krispy Kreme has headquarters operations in Charlotte and Winston-Salem. J.P. Morgan, Morgan Stanley and Citigroup are some of the major banks underwriting the stock.

The 84-year-old company announced in May it was, once again, going public. Krispy Kreme delisted its stock in 2016 after it went private following a $1.35 billion purchase from JAB Holding Company, a private firm that invests in food and beverage brands. It had previously gone public in 2000, and had some difficult years before the 2016 acquisition.

The company has been working to remodel its stores in recent years and has also opened lavish locations showcasing its sugary treats. Last year, Krisy Kreme opened a 4,500-square-foot location in New York City’s Time Square with a glaze waterfall and a 24-hour street-side pickup window.

Krispy Kreme has around 400 locations in the United States. In total, there are 1,400 shops in 33 countries.
