Walmart (0.93) and O'Reilly Auto Parts (0.93) sit at nearly identical scores atop Pizza Hut's top 10 — a two-peak structure that places a mass-market big-box retailer and an automotive parts chain as the two anchors of this audience's shape.
The shape is "two-peak," and the gap between those two leaders and the rest of the set is meaningful. Walmart Pharmacy (0.90) extends the big-box cluster, and Big Box Retailers as a category entity (0.88) reinforces it further. The automotive thread continues with Parts & Accessories (0.87) deeper in the set. Together, big-box retail and automotive parts and accessories account for four of the top 10 neighbors — the two dominant subcategory threads. The remaining neighbors span Sonic (0.89, QSR), Aaron's (0.88, furniture stores), George Strait (0.88, musicians and bands), Aéropostale (0.88, fashion), QSR (0.88), and Dr Pepper (0.88, beverages). No other fast casual dining entity — Pizza Hut's own subcategory — appears in the top 10.
The cross-kind character of this neighbor set is the defining signal: Pizza Hut's audience shape is pulled most strongly toward value-oriented retail and automotive consumers, not toward other restaurant brands.
