TSX:9684.T 25 September 2025

March 20, 2026, 10:31 AM EDT. Diageo PLC (LSE:DGE) has seen a sharp 22% drop in its share price over the past month, continuing a 16% decline across three months, reflecting investor reassessment of its growth and risk outlook. The stock currently trades at £14.02, about 29% undervalued against a £19.81 fair value estimate based on forecasts including 2.7% annual revenue growth and earnings rising to $4.3 billion by 2028. However, Diageo's price-to-earnings (P/E) ratio stands at 17.3, slightly above industry peers but below the fair ratio of 24.1, suggesting mixed market sentiment. Risks include changing alcohol consumption trends and emerging market volatility from regulatory and taxation pressures. Investors face a nuanced outlook balancing downside risks with potential upside from margin improvements and steady sales growth.
