London, Jan 19, 2026, 12:33 GMT — Regular session ongoing.
- Haleon shares fell roughly 0.7% as London stocks pulled back amid new tariff news
- Haleon has appointed Jon Workman as President for Europe, effective immediately
- Attention turns to full-year results on Feb. 25 and updates on U.S.-Europe trade tensions
Haleon (HLN.L) slipped 0.7% to 361.4 pence by 1218 GMT, with investors retreating from UK stocks amid fresh trade concerns. (SharePrices)
The stock plunged amid a wider selloff in London, triggered by U.S. President Donald Trump’s tariff threat against Britain and seven other European countries—unless the U.S. can purchase Greenland. The FTSE 100 dropped 0.6% at 1038 GMT, according to a Reuters report. (Reuters)
This matters because the tariff plan kicks in at 10% on Feb. 1, then jumps to 25% on June 1 unless a deal is struck, according to the Guardian. For Haleon, the macro noise hits as its full-year 2025 results are due Feb. 25—a key date that usually resets expectations around guidance and cash returns. (The Guardian)
“UK and European markets are mirroring the downward trend seen in Asian markets,” Derren Nathan, head of equity research at Hargreaves Lansdown, noted at Monday’s open. He said investors are increasingly cautious over tariff brinkmanship, especially with markets hovering near record highs. (Voxmarkets)
Haleon made a notable move, naming Jon Workman as President, Europe, with immediate effect. This appointment brings Europe onto its executive team and extends Workman’s oversight to include the UK business. “Europe is an important market for Haleon and self-care is a high-priority for people in the region,” Workman said.

Earlier this month, the company announced changes to its operating model aimed at boosting growth and agility. It also promised to provide more details with its preliminary full-year results. (Haleon Corporate)
Trading showed some jitteriness. Haleon shares bounced between 360.9p and 366.8p on Monday, with roughly 1.15 million shares changing hands. That’s down from about 16.5 million on Friday, per Investing.com data. (Investing)
The tariff debate could swing either way for a defensive player like Haleon. If tensions ease, the recent risk-off selling might reverse quickly. But if things heat up, investors will likely brace for softer consumer demand and more complicated cost pressures.
Investors are now focused on any official moves that could alter the tariff schedule. They’ll also be scrutinizing Haleon’s Feb. 25 results for clues on how the strategy is unfolding and what the 2026 guidance looks like.
