Store Brands: The Customer as CompetitorNarrow moat

Procter & Gamble (PG) — moat facet

P&G's fastest-growing customers also sell their own brands beside Tide and Pampers, and P&G spends 70 basis points of margin a year staying visibly better.

The competitor P&G meets on every shelf is the store that owns the shelf. Its 10-K lists "retailers' private-label brands" among its competitors1, and its categories are sold in price tiers, "super-premium, premium, mid-tier and value-tier"2, partly so that a shopper looking for something cheaper can find a P&G product before she reaches the store's own.

The pressure shows in paper and in the cost of staying better.

This is the only competitor that also decides where P&G's products sit, what promotions they get and how much space they receive. The retailers are growing more important to P&G every year: the top ten customers were 35% of net sales in fiscal 2017 and 43% in fiscal 202634, and Walmart alone about 16%5. The Major Clients page covers that concentration; the point here is that the same customers sell products that compete with P&G's.

P&G's defence is performance. Its strategy is built on categories where performance drives brand choice and on superiority in product, package, communication, retail execution and value6. In fiscal 2026 it spent 70 basis points of gross margin on product and package improvements7, the maintenance cost of staying visibly better than the store brand.

The pressure shows most where products are least differentiated. In North American family care, P&G lowered pricing through merchandising investment and still lost 0.7 points of share8.

The battle is sharpest in paper, where family care pricing fell in fiscal 20269, and least visible in razors, where Grooming still took 2% of price10. Where performance is easy to see, the store brand struggles; where a roll of paper looks much like another, it gains.

Call it a permanent competitor that P&G holds off by being worth the difference. The figure that would show it failing is margin: core gross margin was flat at 49.1% in the June 2026 quarter11, and a sustained fall with shares slipping in paper and detergent would mean the store brand is setting P&G's price.

Moat trajectory: Narrowing

Top ten customers 35% to 43% of sales; family care share lost despite price investment.

The number that tests this moat

Core gross margin, latest quarter
49.1%, flat (Q4 FY2026)

The premium P&G still earns over cheaper alternatives; a sustained fall with share loss would mean store brands set the price.
