The Retailer's Private-Label Pivot
Larkfield Grocers operates 240 stores in a mature market where like-for-like sales have fallen 1.8% for three years. Gross margin is 24%, squeezed by discounters who price 15-20% below on comparable baskets. Management proposes shifting from 40% to 60% private-label penetration within two years, cutting national-brand ranges by a third, and investing £40m in own-brand development and packaging. The commercial director warns that national brands drive footfall and that delisting them risks losing 5-8% of sales. The supply chain director notes that own-brand suppliers are concentrated: two firms make 55% of current private-label volume. Customer research shows shoppers trust Larkfield's quality but see no reason to switch from discounters for staples. The CFO wants a payback calculation before committing.
1. Evaluate the strategic logic of the private-label pivot and the principal risks it creates.
Read the worked answer
The logic is coherent: with like-for-like sales falling and discounters 15-20% cheaper, Larkfield cannot win a price war on national brands whose margins are thin and whose prices it does not control. Private label raises margin per unit, differentiates the offer, and builds customer loyalty that discounters' copycat ranges cannot easily replicate. Moving from 40% to 60% is ambitious but directionally sensible for a mature-market grocer seeking margin rather than volume growth.
The risks are specific. Footfall risk: the commercial director's 5-8% sales loss estimate is plausible if brands are traffic drivers, so range cuts should target low-velocity brands rather than blanket delisting. Supply concentration is the sharpest risk: two suppliers making 55% of own-brand volume creates single-point failure and bargaining exposure, and scaling to 60% penetration without supplier diversification would deepen dependence. Capability risk: £40m on development and packaging is necessary but insufficient if quality consistency and innovation pipelines are weak. Demand risk: research says shoppers see no reason to switch for staples, so the pivot must target categories where quality differentiation is credible, not staples where discounters win on price. The pivot is defensible only as a selective, category-by-category programme with supplier diversification and a staged payback test, not a blanket two-year target.
2. Advise the CFO on what the payback appraisal should include beyond the £40m investment.

A narrow payback on £40m would mislead. The appraisal should model the full economics. Benefits: margin uplift on converted volume, using category-level gross margin differentials rather than an average; incremental loyalty and basket effects where evidence supports them; and reduced promotional spend as own-brand dependence on national-brand promotions falls. Costs: the £40m investment; delisting costs including lost sales and any contractual exit payments; supplier development and dual-sourcing costs to reduce concentration; marketing to overcome the 'no reason to switch' finding; and possible price investment to close the discounter gap on staples.
The appraisal should be scenario-based rather than single-point. A base case, a downside case with the commercial director's 5-8% sales loss, and a supply-disruption case should be modelled, with payback and net present value for each. Sensitivity analysis should identify which assumption drives the answer, likely the sales-loss rate and the margin differential. The CFO should also require stage gates: release funding by category cohort so evidence from early conversions informs later commitments. Finally, the appraisal should state what would make the programme stop, a pre-agreed trigger such as footfall decline beyond a threshold, so the decision is reversible.
