On 18 July 2022, Haleon listed as an independent company on the London and New York stock exchanges. Haleon is the result of the combination of three consumer health businesses, GSK, Novartis and Pfizer, over the last decade.

While Haleon is still a young company, some of our brands have over 170 years’ worth of history. The early foundations to what is today Haleon are in a single apothecary shop in London, opened in 1715 by Silvanus Bevan. Over the centuries our legacy companies have been founded, grown, acquired and merged, leading to the creation of Haleon which has one purpose – to deliver better everyday health with humanity.
