Associated British Foods has announced the demerger of its retail arm, Primark, from its diversified foods portfolio. The split creates two pure‑play FTSE 100 entities – a fast‑fashion chain and a conglomerate of brands ranging from Twinings tea to sugar. Investors have pressed for the move for years, and the separation mirrors recent conglomerate break‑ups across Europe.

Analysts peg Primark’s value around £13.4bn, using an estimated £1.7bn EBITDA and an eight‑times H&M multiple. Despite a 5.6% dip in European sales, the chain could approach Next’s 11‑times EBITDA, adding roughly £5bn to its worth. The foods division, likened to Premier Foods, is valued near £8.5bn, pushing the combined split to about £22bn, well above ABF’s £16.4bn market cap.

The de‑merger eliminates operational overlap, allowing each business to focus capital on its core strengths. Primark can accelerate technology upgrades, expand e‑commerce and sharpen pricing, while the foods arm must address under‑performing assets such as its sugar unit. Shareholders stand to gain from clearer valuations and potential dividend lifts as the two entities trade independently.

Market reaction has been upbeat, with FTSE 100 indices ticking higher as investors price in the unlocking of value. Comparable splits at Unilever and Danone showed similar premium lifts, reinforcing the case for pure‑play structures. The split also positions Primark to compete more aggressively with H&M and Zara on price and digital reach.
