AB Foods to split Primark and food business into two FTSE 100 companies

The split should narrow the valuation discount created by conglomerate complexity, but the bigger second-order effect is that each business will be forced to compete on its own balance sheet and capital allocation discipline. That usually benefits the higher-quality growth asset first: a pure-play retail format can get a cleaner multiple if investors believe unit economics are durable, while the food arm may actually de-rate initially as it loses the internal subsidy of being paired with a faster-growing consumer brand.

The hidden winner may be landlords and suppliers rather than the new listed entities. A standalone retail business is more likely to push harder on lease resets, working-capital terms, and inventory turns, which can compress margins across the apparel supply chain over the next 2-3 reporting cycles. If Primark is the more visible equity story, competitors in value apparel could face multiple compression even without direct share loss, because investors will benchmark them against a more transparent, capital-light peer.

The main risk is that the demerger is a structural event, but the rerating is not immediate. In the next 1-3 months, execution risk around separation costs, stranded overhead, and index mechanics can dominate fundamentals; over 12-18 months, the key determinant is whether each business can sustain returns without cross-subsidy. If consumer demand softens, the market may conclude the split merely exposed two slower-growth businesses instead of unlocking value.

Consensus likely underestimates how much optionality this creates for future M&A. Once separated, either piece becomes a cleaner acquisition target: Primark as a strategic bolt-on for a global apparel platform, or FoodCo as a defensive staple asset for a domestic or international food group. That takeover optionality is real, but it only matters if management keeps leverage modest and avoids using the transaction to mask weak operating momentum.
