In-N-Out may expand to these 3 states next, owner Lynsi Snyder says, as the 445-location burger chain pushes farther east

In-N-Out is considering expanding into Arkansas, Mississippi and Oklahoma, where its existing Texas-based supply route could support new locations; the chain also plans to open in New Mexico next year and expand in California. It operates 445 restaurants across 10 states, including 289 in California, and reported domestic sales growth of about 10% last year versus 2024, according to the Wall Street Journal citing Technomic.

Analysis

The key economic signal is route density, not the possibility of three new state entries by itself. If In-N-Out can serve additional locations from its existing Texas-linked network, incremental volume could improve distribution utilization and make nearby markets more attractive; that advantage is conditional on capacity, freshness requirements, and actual restaurant commitments. Conversely, entering new markets still entails local build-out and operating costs, so a reported sales-growth figure does not establish attractive unit economics.

For SHAK, this is a competitive watch item rather than a near-term earnings shock: the article provides no store-level overlap, opening schedule, or evidence that the two chains target the same customer occasion. A stronger regional burger category could validate demand, while In-N-Out’s potential footprint could raise the bar for traffic and value perceptions where they eventually compete. Do not infer a SHAK revenue or margin impact until overlap and customer substitution are measurable.

Days: limited investable information; the expansion is under consideration, not a disclosed rollout. Over 1–3 months, watch for confirmed sites, timing, and distribution-capacity details. Over 6–18 months, execution and repeatable unit economics matter more than announcements. The thesis weakens if the company does not commit to locations, or if SHAK reports resilient traffic and guidance despite confirmed local competition.

Key Decisions for Investors

• No immediate directional SHAK trade: the report lacks confirmed locations, timing, and evidence of direct market overlap.
• Set an alert for confirmed In-N-Out openings in markets where SHAK operates; then assess local traffic, pricing, and comparable-sales commentary before sizing any relative-value position.
• For any eventual SHAK short thesis, require corroboration in traffic or comparable-sales deterioration and/or guidance revision—not expansion headlines alone. Falsifier: SHAK maintains or raises comparable-sales and traffic outlook after overlap is established.
• Track whether new locations can be supplied through existing distribution infrastructure and whether openings proceed on schedule; delays or added network investment would weaken the route-density advantage.
