What Guinness Knows That the Rest of the Diageo Portfolio Does Not

In February 2026, Diageo published its interim results for the six months ended 31 December 2025. The document runs to dozens of pages and contains a significant amount of bad news. US Spirits down 9.3% organically. Don Julio down 20.9%. Casamigos down 30.9%. The interim dividend cut by 51%. Net debt of $21.7 billion. A new Chief Executive, Sir Dave Lewis, describing the work ahead as significant.

Inside the same document, largely unremarked upon in the coverage that followed, was a brand growing 10.9% organically and delivering growth in every region it operates in apart from Asia Pacific.

That brand is Guinness. And the contrast between its performance and the rest of the Diageo portfolio is not a coincidence. It is an argument.
