Haleon PLC stock slides on operating model shake-up as investors look to Feb. 25 results

London, Jan 10, 2026, 09:43 GMT — Market closed

Haleon shares closed down 1.18% at 367.50 pence on Friday after the consumer health group set out plans to revamp its operating model, redrawing regional lines and adding new senior roles. A filing showed the changes are due to be in place by mid-2026, even as London’s FTSE 100 logged a record close. 1

The timing matters. Haleon is trying to push its “Win as One” strategy from last year from slides into day-to-day execution, and the market will look for proof in growth and productivity rather than another org chart. Chief executive Brian McNamara said the shift should leave Haleon “a simpler and more agile and efficient organisation.” 2

The “operating model” is corporate shorthand for how the business is run — who owns decisions, and who carries the numbers. Haleon plans six “operating units”, regional businesses accountable for performance, including splitting its EMEA and Latin America set-up into three and making India Subcontinent a stand-alone unit separate from Asia Pacific, the announcement said. 3

Haleon has appointed Filippo Lanzi as Chief Growth Officer and Björn Timelin as Chief Transformation Officer, according to executive team biographies on its website. It also named Kedar Lele to run the new India Subcontinent unit. 4

The stock ranged between 365.90p and 373.90p on Friday and Haleon’s market value stands at about £32.7 billion, according to Hargreaves Lansdown data. It is about 12% below its 52-week high of 419.40p and roughly 13% above the 52-week low of 325.10p. 5

In New York, Haleon’s ADRs closed down 1.29% at $9.91 on Friday. 6

The catch is execution. Haleon did not put numbers on any costs, savings or timing bumps in its announcement, and consultation with employee representatives can stretch timetables or force changes. If the reorganisation distracts from selling toothpaste and pain relief in key markets, the market will not wait around.

The next hard catalyst is Haleon’s full-year 2025 results on Feb. 25, when investors expect more detail on the new set-up and what it changes — if anything — about growth, margins and cash flow. The following marker is its first-quarter trading update on April 29. 7
