Associated British Foods stock (ISIN GB0006731235) dropped sharply in London trading on September 10, 2026, with the shares down about 9 to 10 percent after the group’s latest fourth-quarter trading update highlighted weaker Primark like-for-like sales and a worsening outlook for its Sugar division.

Q4 trading update puts Primark and Sugar in focus

Associated British Foods plc, the owner of Primark, published a trading update for the fourth quarter of its 2026 financial year, which ends on September 12, 2026, outlining expectations for the full year and key divisional trends.Associated British Foods said group adjusted operating profit for the 2026 financial year is expected to be broadly in line with previous expectations, while adjusted earnings per share for the year is now expected to be ahead of earlier forecasts.

In retail, the company indicated that for the 2026 financial year Primark’s total sales are expected to grow around 2 percent, supported by new store openings and its franchise model.Associated British Foods also flagged that Primark’s like-for-like sales are expected to fall around 2.6 percent for the full year 2026, pointing to pressure from weak consumer confidence in continental Europe and weather effects in key markets.

Heatwave and consumer demand weigh on sales

The trading update and related coverage highlighted how summer weather patterns and demand dynamics have affected performance in several AB Foods businesses. As AJ Bell reported on September 10, 2026, AB Foods noted that the prolonged summer heatwave dented sales in its Primark stores and in tea, contributing to the weaker like-for-like performance and putting pressure on parts of its Grocery division.

Within Grocery, Twinings and Ovaltine were singled out as areas of short-term weakness. According to FoodNavigator on September 10, 2026, the company expects Grocery’s adjusted operating profit for the 2026 financial year to be below its earlier expectations, mainly due to reduced Twinings tea sales from the hot summer and softer Ovaltine performance.

In contrast, the Ingredients division is expected to deliver solid growth. The same FoodNavigator report noted that AB Foods expects Ingredients sales in the fourth quarter of 2026 to increase by approximately 10 percent compared with the prior-year period, underlining how some industrial and specialty ingredients businesses are benefiting from robust customer demand despite broader consumer headwinds.

Sugar loss guidance shifts to upper end of range

For the Sugar division, the trading update pointed to a more challenging picture. AB Foods now expects Sugar to post an adjusted operating loss for the 2026 financial year toward the upper end of its previously guided range of GBP 25 million to GBP 60 million.Investing.com linked this higher loss guidance to lower European sugar prices, increased gas costs and provisions for onerous contracts.

The same Investing.com coverage reported that AB Foods is already guiding for a wider adjusted operating loss in Sugar in 2027, with a range of GBP 70 million to GBP 170 million, citing potential risks including higher gas costs and weather impacts in Africa. For investors, this widening loss range in Sugar is a key risk factor that now sits alongside Primark’s weaker like-for-like trends.

AB Foods also referenced its July 2026 acquisition of Hovis in the trading update, noting that the newly acquired bread and bakery business is expected to dilute profits in 2027 before cost synergies and integration benefits are realised.FoodNavigator pointed out that this adds another layer of execution risk at a time when AB Foods is balancing investments in Primark and its food operations.

Share price reaction and market metrics

Market reaction to the update was immediate and negative. Investing.com reported that AB Foods shares fell more than 9 percent in early London trading on September 10, 2026, after the company detailed the expected 3 percent decline in Primark like-for-like sales in the fourth quarter and the higher Sugar loss guidance.Investing.com indicated that by around 07:08 GMT the shares were down more than 9 percent in the London market.

A separate winners-and-losers overview from Morningstar via Alliance News on September 10, 2026 noted AB Foods down 10 percent at 1,808.5 pence, with a 12-month trading range between 1,729.45 pence and 2,359.00 pence. That pricing shows the stock moving close to the lower end of its 52-week range after the update, underlining the scale of the market’s repricing of the Primark and Sugar outlook.

Later in the morning, AJ Bell reported that AB Foods shares were down 9.7 percent to 1,824.00 pence in London on September 10, 2026, reinforcing the picture of a high single-digit to low double-digit percentage drop on the day.AJ Bell also highlighted that AB Foods plans to launch a home-delivery offering for Primark, a strategic response that could help offset some of the pressure on store-based sales over time.

Analyst and investor perspective

The sharp move in Associated British Foods stock came against a backdrop of cautious analyst sentiment. A recent overview on MarketBeat notes that AB Foods has a consensus rating of Reduce, based on a mix of hold and sell recommendations from covering analysts. The same overview cites a consensus price target of 1,808.57 pence, implying downside of about 10.5 percent from a reference price of 2,020 pence given in that analyst compilation.

That earlier consensus price target and rating context helps explain why the market reaction to the Q4 trading update was so pronounced. With Primark like-for-like sales expected to decline around 2.6 percent in the 2026 financial year and the Sugar loss range shifting toward the upper end of GBP 25 million to GBP 60 million, the trading update reinforced concerns that had already been reflected in cautious analyst views.Invezz reported that AB Foods stock fell more than 11 percent on September 10, 2026 at one point during trading as investors reassessed the pace of any turnaround in Primark and the duration of Sugar headwinds.

At the same time, the trading update’s guidance that group adjusted operating profit for 2026 should be broadly in line with previous expectations, and that adjusted earnings per share are expected to be ahead, offers a degree of support for the investment case.Associated British Foods is signalling that despite divisional pressures, the overall group is on track to deliver earnings that exceed earlier expectations, helped by contributions from Ingredients and parts of its Grocery and Agriculture operations.

Next results date and what investors watch

Looking ahead, Associated British Foods has scheduled the announcement of its full-year results for the 52 weeks to September 12, 2026 for November 3, 2026.Associated British Foods said an investor and analyst call will be held at 08:00 on that day, offering shareholders and analysts a detailed view of divisional performance, margin trends and the outlook into the 2027 financial year.

For investors following AB Foods stock into that full-year release, several numeric checkpoints from the Q4 update stand out. One is how close Primark’s like-for-like sales decline for the quarter and for the year lands relative to the indicated 3 percent drop for the fourth quarter and the around 2.6 percent decline for the full year 2026.Investing.com underscored that Primark’s like-for-like sales in the fourth quarter to September 12, 2026 are expected to fall 3 percent, with United Kingdom and Ireland like-for-like sales up 0.4 percent and continental Europe down 4.3 percent.

A second checkpoint is the eventual adjusted operating loss recorded for Sugar in the 2026 financial year versus the guided GBP 25 million to GBP 60 million range and the early view for a GBP 70 million to GBP 170 million loss in 2027.Investing.com highlighted the risk that this part of the business could see larger losses as gas prices, sugar prices and weather-related issues in Africa evolve.

Stock trades near lower end of its range

As of the September 10, 2026 trading session referenced in Alliance News via Morningstar, AB Foods stock was quoted around 1,808.5 pence on the London Stock Exchange, down about 10 percent on the day and close to the lower bound of its 12-month range of 1,729.45 pence to 2,359.00 pence.Morningstar via Alliance News described AB Foods as one of the notable decliners in a session where consumer stocks retreated.

For shareholders, that positioning near the bottom of the 52-week range sets the stage for the November 3, 2026 full-year report to act as a potential catalyst. If AB Foods confirms that group adjusted operating profit is indeed in line with previous expectations and adjusted earnings per share is ahead, while offering clearer paths to stabilise Primark like-for-like sales and narrow Sugar losses, the stock’s valuation and the Reduce-rated analyst consensus could be reassessed. Until then, the numbers embedded in the latest trading update – a 2 percent expected rise in Primark’s full-year sales, a roughly 2.6 percent decline in Primark like-for-like sales for 2026, and a Sugar loss at the upper end of GBP 25 million to GBP 60 million – will remain central to how the market values AB Foods stock.
