Jersey Mike’s Subs made a shaky debut on the public market, with the Blackstone-backed company’s shares falling after its $1 billion US initial public offering. Bloomberg’s report says the stock dropped 8.7% after the listing, signaling a weak start for the sandwich chain as a newly public company.

The IPO raised about $1 billion from the company and certain existing shareholders. The offering was priced at the midpoint of its marketed range, suggesting the deal came together without pushing above expectations set during the roadshow.

A first-day decline after an IPO can reflect cautious investor sentiment, and Jersey Mike’s early trading appeared to show limited enthusiasm despite the size of the deal. The drop also stood out because the company entered the market with backing from Blackstone, one of the best-known investment firms tied to consumer and restaurant businesses.

The debut now puts attention on how Jersey Mike’s performs in the sessions ahead, as investors weigh its growth story against the pressure that can follow a major public listing. For now, the company’s stock market launch was marked more by the post-IPO slide than by the capital it raised.
