Umpqua Bank pulls away from the rest of Banner Bank's top 10 at 0.88 — a gap of more than 12 points to the next nearest neighbor, making this one of the clearest single-neighbor spikes in the data.

The shape is "spike" in the strict sense: one fellow bank dominates, and the remaining nine neighbors scatter across entirely different categories. After Umpqua, the list moves immediately into Miracle-Ear (0.75, Health and Medical Services), Cumberland Farms (0.74, Gas Stations), and Washington Federal (0.73, Banks) — the only other bank in the top 10. From there, the neighbors spread across Home Goods and Furnishings (Floors To Go, 0.72; Flooring America, 0.71), Fitness Centers and Gyms (Anytime Fitness, 0.72), B2B Services (RDO Equipment Co, 0.72), and Health and Medical Services again (Health & Medical Services, 0.71), closing with another Gas Station (Good 2 Go Stores, 0.70). Only two of the ten neighbors share Banner Bank's Banks subcategory; the other eight span six distinct subcategories. The cross-kind character of the cluster — flooring retailers, gas stations, hearing health providers, a gym chain — suggests the audience shape is driven by something structural rather than by financial-services affinity alone.

The dominant Umpqua signal aside, Banner Bank's audience profile is defined less by its own category than by a broad, regionally-rooted consumer pattern that cuts across home, health, and everyday-service brands.
