Yes — Roysters Bubbled Chips is ultra-processed.
Ultra-processed; best enjoyed occasionally rather than as an everyday snack.
This product is ultra-processed because it contains several industrial additives and refined ingredients: dried yeast extract (a flavor enhancer), glucose syrup and maltodextrin (industrially processed sugars), natural flavoring, and emulsifier mono- and diglycerides of fatty acids. The rice flour, sunflower oil, sugar, spices, dried vegetables, and fortified wheat flour are not independently UPF under the stated criteria, but the identified additives make the finished product UPF.
Other crisps, snacks & nuts Nomi has checked — these ones aren't ultra-processed.

The classification is based on the NOVA system used by researchers and dietitians worldwide.
