The trailing 4-week (28-day) average of year-over-year (YoY) sales growth for June 2026 came in at:
| Segment | YoY Sales Growth (28-day avg.) |

Looking at the 7-day moving average, both segments posted positive growth for most of the month. Growth peaked around Father's Day and Juneteenth weekend, when Fast Casual hit +3% and Full Service reached +8% — the strongest single-week performance of the month for both segments.
