Jersey Mike’s (JMKE) Owns the Sub Business. Winning Over Younger Diners is the Next Fight

On September 1, 2026, the Wall Street Journal reported that Jersey Mike's Subs Inc., a Blackstone-backed sandwich chain that went public in July, currently dominates affluent, older customers but faces challenges in appealing to Generation Z, which currently accounts for only 2% of its customer base. CEO Charlie Morrison, a former Wingstop executive, emphasized the importance of proactively targeting younger consumers amid competition from fast-casual chains already leading in that demographic.

The company demonstrated strong unit economics, generating around $1.4 million in average unit volume, far exceeding Subway's estimated $500,000. Second-quarter same-store sales increased by 2.3%, driven by higher transactions, while systemwide sales soared 10% to $1.21 billion. Management anticipates third-quarter same-store sales to climb by 3%-4%, indicating ongoing sales momentum despite the Gen Z challenge.

To address this deficiency, Jersey Mike's has intensified its digital marketing efforts, increasing spend from under 1% to over 20% of total marketing spend. Loyalty registrations also surged by 22% year-to-date. Furthermore, the company observed enhanced engagement among Gen Z and Hispanic consumers, suggesting that these initiatives could broaden its customer base.

However, Jersey Mike's still heavily relies on older customers, with Gen X and Baby Boomers comprising about 70% of its clientele. The company faces profitability pressures, with second-quarter net income dropping 37% to $37 million due to increased general and administrative expenses, advertising costs, and interest expenses. To sustain top-line growth, the company must leverage its digital marketing investments and expand its store network to generate sufficient incremental sales.

The company is yet to prove it can reach its $2 million average-unit-volume target, which requires consistent transaction growth, heightened customer frequency, and successful onboarding of younger customers. If the Gen Z strategy fails to generate lasting traffic, management might struggle to meet its long-term growth projections. While Jersey Mike's boasts robust store profits and rising sales, the company must demonstrate its ability to attract Gen Z customers and translate higher sales into greater profitability.
