Jersey Mike's Subs is a leading fast-casual restaurant chain specializing in submarine sandwiches. Founded in 1956 and headquartered in New Jersey, the company has grown to over 3,300 locations primarily across the United States, with a growing international presence in Canada and planned expansions into the UK and Ireland. Jersey Mike's operates an asset-light, 99%-franchised business model. Its revenue is primarily generated through royalties and advertising fees tied to systemwide sales, which exceeded $4.2 billion in 2025. The company's corporate team oversees franchise relationships, brand standards, real estate development, and supply chain logistics, while independent franchise owners are responsible for staffing and running individual locations. Jersey Mike's differentiates itself through its commitment to high-quality ingredients, including fresh-sliced meats and cheeses, bread baked in-store daily, and produce prepared on-site. The brand boasts strong unit economics, with an average unit volume (AUV) of approximately $1.4 million in 2025. Backed by private equity firm Blackstone, which acquired a majority stake in 2024, Jersey Mike's filed for an initial public offering in July 2026 to further accelerate its domestic and international expansion.
