A company built on Henry Wellcome’s 1880 foundation sold its own charity to itself — then paid $3 billion to settle the largest healthcare fraud case in US history.
GSK plc is a British multinational pharmaceutical and biotechnology company formed in 2000 by the merger of Glaxo Wellcome and SmithKline Beecham. It traces its origins to Henry Wellcome’s 1880 co-founding of Burroughs Wellcome & Company. GSK developed the first malaria vaccine (RTS,S), markets WHO-listed essential medicines, and reported $42.4 billion in revenue and $9.32 billion in earnings in 2025. In 2012, it pleaded guilty in the US to unlawful drug promotion, failure to report safety data, and physician kickbacks — agreeing to a $3 billion settlement, the largest healthcare fraud case in US history and the largest in the pharmaceutical industry. The Wellcome Foundation Ltd., established by Henry Wellcome in 1924, was later sold to GSK following changes in UK charity law.
GSK’s 2000 formation was the endpoint of over a century of pharmaceutical mergers — beginning with Henry Wellcome’s 1880 co-founding of Burroughs Wellcome & Company.

The Scale
GSK’s scale is measurable: $42.4 billion in revenue and $9.32 billion in earnings in 2025 placed it tenth among global pharma companies.

The Public Health Claim
GSK markets WHO-listed essential medicines and developed the first malaria vaccine — but committed in 2014 to pricing RTS,S at only five per cent above cost in developing countries.

The Settlement
In 2012, GSK pleaded guilty in the US to unlawful drug promotion, safety-data suppression, and physician kickbacks — resulting in a $3 billion settlement, the largest in pharmaceutical history.

The Foundation Sale
Henry Wellcome consolidated his commercial activities under The Wellcome Foundation Ltd. in 1924 — and that foundation was later sold to GSK after UK charity law changed.

The written brief1 min read
What the company or idea is
GSK plc is a British multinational pharmaceutical and biotechnology company formed in 2000 by the merger of Glaxo Wellcome and SmithKline Beecham, itself built from earlier firms including Henry Wellcome’s Burroughs Wellcome & Company (founded 1880).
How it actually makes money
GSK makes money by selling prescription drugs, vaccines, and consumer healthcare products globally. Its 2025 revenues were $42.4 billion, with earnings of $9.32 billion.
What works
GSK developed the first malaria vaccine (RTS,S) and markets WHO-listed essential medicines including amoxicillin, mercaptopurine, pyrimethamine, and zidovudine — all legacy products from predecessor companies.
What does not
Its self-presentation as a public-health steward collapses against its 2012 $3 billion US fraud settlement — the largest in pharmaceutical history — for unlawful promotion, safety-data suppression, and physician kickbacks.
What to take from it
The gap between GSK’s WHO-listed essential medicines and its record-breaking fraud settlement reveals how regulatory enforcement, not corporate intent, shapes real-world health outcomes.
Is it worth your time
Yes — as a case study in how legacy pharmaceutical consolidation produces both essential medicines and systemic compliance failure, without requiring speculation about motives or culture.
