Yes — Unsmoked bacon medallions is ultra-processed.
Not ideal for everyday eating because it is an ultra-processed cured meat.
Unsmoked bacon medallions are ultra-processed under the specified NOVA guidance because they contain curing preservatives—sodium nitrite and potassium nitrate—and the antioxidant E301 (sodium ascorbate), which are industrial additives used in a processed meat formulation. The pork, water, and salt themselves do not drive the classification, but the curing additives do.
Other meat & poultry Nomi has checked — these ones aren't ultra-processed.

Ultra-processed foods (UPFs) are industrial formulations made with ingredients and additives you wouldn't find in a home kitchen — such as emulsifiers, artificial flavourings, colourings and modified starches. The classification is based on the NOVA system used by researchers and dietitians worldwide.
