Diageo has revised its financial forecasts downwards after experiencing unsuccessful sales performance globally, with particular weakness evident in the US and Chinese markets.
The drinks giant has also encountered supply chain challenges, with stock shortages preventing the company from fulfilling customer demand.
These difficulties have contributed to a significant decline in Diageo's stock price, as investor confidence in the beverage manufacturer wavers.
Declining performance across key markets
Diageo stands as a global leader in premium spirits, running numerous whisky distilleries worldwide.
The company manages more than 200 brands, combining innovative new products with established names. Its portfolio includes brands such as Don Julio tequila, Smirnoff Vodka, Johnnie Walker whisky and Guinness.
The company's most recent financial report, covering the six-month period ending 31 December 2025, revealed declines in both net sales and operating profit.
The results highlighted the scale of challenges facing new CEO Sir Dave Lewis, whilst also undoing progress the company had achieved previously.
Reported net sales fell by 4%, attributed to organic net sales decline combined with the negative effect of disposals.
Whilst Europe, Latin America and the Caribbean (LAC) and Africa showed organic net sales growth, overall organic net sales still declined by 2.8%. Reported operating profit decreased by 1.2%.
Additionally, net cash flow from operating activities dropped by US$202m to US$2.1bn.
Free cash flow fell by US$164m to US$1.5bn.
Dave says: "Our performance in the first half of fiscal 26 was mixed. Strong performance in Europe, LAC and Africa, was offset by a weakening performance in North America (NAM) and continued weakness in Chinese white spirits in Asia Pacific (APAC).
"Only several weeks in I can already see significant opportunities for Diageo to act more decisively to enhance its competitiveness and broaden the portfolio offering leading to higher growth.
"To deliver on these opportunities, we need to create more financial flexibility. Accordingly, the Board has taken the difficult decision to reduce the dividend to a more appropriate level which will accelerate the strengthening of our balance sheet."
After the report's publication, Diageo shares dropped 13% by market close.
This represents the company's worst single trading session since its formation in 1997, when Guinness merged with Grand Metropolitan.
Market value takes substantial hit
Diageo's market value decreased by more than £5bn (US$6.69bn) following the financial announcement.
The board's decision to reduce its dividend to US$0.20 per share represents a dramatic cut from US$40.5 in the previous year.
Whilst Diageo faces significant challenges this year, the broader drinks sector has experienced pressure from inflation and evolving consumer behaviour.
According to Morningstar, Gen Z consumers drink 20% less alcohol than millennials, indicating a shift in consumption patterns and a contracting customer base.
Furthermore, tariff increases and global inflation have driven wider changes in consumer spending habits as individuals tighten budgets and reassess priorities.
Sir Dave suggests that consumers are drinking less frequently when they choose to consume alcohol at all, which will influence a strategic shift.
Moving forward, Diageo plans to offer smaller pack sizes that could satisfy customer preferences whilst acknowledging their constrained budgets.
Guinness demand outstrips availability
Although sales of certain spirits categories have experienced declines, Guinness has been identified as a strong performer within the brand, demonstrating substantial growth across North America and maintaining ongoing popularity throughout the UK.
The beverage, once primarily consumed by an older demographic, has now been embraced by younger drinkers.
This expansion has created supply challenges, with growing difficulties in meeting demand.
London has particularly experienced Guinness supply shortages – attracting attention when Diageo launched a Guinness experience venue recently.
Notwithstanding Guinness' increasing success, the company faces a challenging position.
Repeated failure to meet demand could result in customer losses, potentially undermining even Guinness' ability to support the drinks company's performance.
Whilst the dividend reduction was designed to help protect the organisation, the sharp sales decline will have a more substantial impact on the company, potentially making recovery more challenging than initially expected.
Dave, however, has already developed a recovery plan and, given his experience in implementing cost-saving measures for brands, this may prove sufficient to help Diageo's supply chain resume normal operations.
