Haleon has a Margin Engine
But not a volume engine. And that will be a problem.
H1 2026: gross margin up 140bps CER to 66.5%, against a 50 to 80bps annual target. Organic volume/mix growth: 0.5%. Reckitt and Unilever both grew volume faster.
Haleon’s gross margin rose 140 basis points in H1 2026, at constant exchange rates. Its own annual target was 50 to 80 basis points.
Beating a cost target by roughly double sounds like unambiguous good news. On its own, it rarely is. The question that actually matters is where that margin came from, and where it went once Haleon had it.
The Margin Beat Its Own Target. The Question Is What Funded It.
Group revenue reached £5.6 billion in H1 2026, up 2.6% organically. Price did most of the work, contributing 2.1 percentage points. Volume and mix added only 0.5 points. The quarterly trend improved. Organic growth accelerated from 2.2% in Q1 to 3.1% in Q2, with the mix rebalancing to 1.7% price and 1.4% volume and mix.
Adjusted operating profit reached £1,364 million, up 8.2% at constant currency and 9.7% at actual rates. Adjusted operating margin expanded 120 basis points at constant currency to 24.3%, with a further 40 basis point currency tailwind at actual rates. Reported operating profit told a different story: it fell 2.6% to £1,172 million, dragged down by restructuring charges tied to a new corporate operating model.
That gap between the adjusted and reported numbers is the first thing to sit with. The adjusted figures are the ones management wants read out loud. The reported figures are the ones that actually landed on the P&L.
Free cash flow held up at £769 million, up £35 million year on year, with leverage steady at 2.5x net debt to adjusted EBITDA. Capital allocation went two places. Haleon completed £457 million of a £500 million share buyback programme. It also raised the interim dividend 9% to 2.4p per share. Call this the extraction gap. It is the widening distance between two speeds. One is how efficiently a company pulls margin out of its existing base. The other is how fast it grows that base in the first place. Haleon is excellent at the first half of that equation. The second half grew 0.5% in H1.
