How Diageo makes money
Diageo makes money by producing branded alcoholic drinks and selling them through distribution channels in markets worldwide. Much of its revenue comes from a portfolio of well-known brands that it builds through marketing.
What Diageo does
Diageo is a London-based drinks company. It was incorporated in 1886 and was known as Guinness plc until it changed its name in February 1998. Its portfolio covers most major drink types: Scotch, Irish, Canadian, US, Indian and Chinese whisky, vodka, gin, rum, tequila, brandy, cachaça, raki, liqueurs, beer and wine. It also sells ready-to-drink and non-alcoholic products. The business is built on a set of well-known brands. These include Johnnie Walker and Buchanan's Scotch, Guinness stout, Smirnoff vodka, Baileys liqueur, Captain Morgan rum, Crown Royal Canadian whisky, and Don Julio and Casamigos tequila. It also owns brands aimed at specific regions, such as McDowell's in India and Shui Jing Fang Chinese white spirit. Diageo sells in every major region, so its results depend on consumer drinking habits around the world.

What is Diageo worth?
On an owner-earnings DCF, Diageo's most-likely value is about $77 versus a recent price near $87 (12% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$41) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
⚠ High leverage — net debt is 9.3× annual cash flow. Net debt is subtracted from this fair value, but refinancing at higher rates, principal timing, and share dilution aren’t modeled — the equity can be worth far less if cash flow weakens.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
