The Shop a 17-Year-Old Bought.
Filed for IPO by PE in 18 Months.

On July 2, 2026, Jersey Mike’s Subs filed its S-1 with the SEC. Founded in 1956, it has 3,300 stores across all 50 U.S. states and Canada — 99% of them franchised. The combined amount its stores ring up (systemwide sales) reaches about $4.3 billion over the twelve months through March 2026.

But the star of this S-1 is not the sandwich. On January 16, 2025, the investment firm Blackstone bought a majority of the company. From there, in about 18 months, Jersey Mike’s files to go public.

The anomaly in the numbers is in net income. It grew to $11 million in 2021 and $21 million in 2023, then fell sharply to $5 million in 2024 (a net margin of 1%), before recovering to $55 million in 2025 — even though revenue rose every year.

What dug the trough was not interest. What swelled in 2024 was founder-era SG&A ($262 million to $349 million); interest expense rose by only $2 million. In 2025 those costs came out, SG&A fell to $233 million, and net income recovered even as interest doubled. Then, in February 2026, part of the proceeds of a newly issued note went to a dividend to Blackstone. Before the listing, the PE firm has begun recovering the capital it put in.

Ten questions. We lay out only what the S-1 says.

Question 1

What is this company, really?

In one line: this is not a company that sells sandwiches, but one that lends out its sign.

What Jersey Mike’s sells is not the sandwich itself. It lends its brand and its system to people who want to open a store — the franchise owners — and collects a fee out of each store’s sales. That is what a franchisor does.

“

We are Jersey Mike’s: A high-growth franchisor of fast casual, submarine-style sandwich restaurants specializing in authentic, hand-crafted, craveable subs.

JERSEY MIKE’S S-1 (JULY 2026) — PROSPECTUS SUMMARY

A “sub” is a submarine sandwich — fillings packed into a long roll shaped like a submarine. Of the 3,300 stores across all 50 states and Canada, only a handful are company-owned; 99% belong to franchisees.

The company has a founding story it keeps retelling. In 1956, a single sub shop was born in a seaside town in New Jersey. Nineteen years later, in 1975, a 17-year-old high-school boy borrowed money from his football coach and bought the shop outright.

That 17-year-old was Peter Cancro, the founder today. He began franchising in 1987 and, in the 50 years since that purchase, grew one shop into 3,300. Then, in 2024, he decided to sell a majority of the company to Blackstone.

Here is the design philosophy that defines the company’s character: the franchisees pay to build the stores, and headquarters spreads nationwide on minimal capital. The prospectus calls this an asset-light model.

The franchisee grills the sandwich; headquarters lends the sign and the recipe.

Question 2

What does it compete on?

There are two battlegrounds: a way of earning that needs almost no capital, and a brand too strong to ignore.

Jersey Mike’s strengths, boiled down, come to two pillars. The first is a revenue structure that takes a thin, broad fee from franchisees. The second is the power of a brand customers ask for by name.

A way of earning that needs no capital — a 6.5% royalty

Headquarters’ main income is a “royalty” — 6.5% of a franchisee’s gross receipts, collected continuously. The franchisee builds the store; headquarters lends the recipe and the sign and skims part of the sales.

“

We employ an asset-light, 99%-franchised business model that generates high operating margins that requires minimal capital expenditures.

JERSEY MIKE’S S-1 (JULY 2026) — COMPETITIVE STRENGTHS

Because of this structure, against total revenue of about $696 million, the Adjusted EBITDA margin reaches 47% — an extraordinarily high level for a restaurant chain.
