Would a major cyberattack make you less trusting of the stores you shop at?
Ahold Delhaize lowered its full-year forecasts after a cyberattack paralyzed many of its IT systems for more than a week in October. The retailer preventively took down online stores, apps and other systems in Europe and the U.S. in mid-October.
Why it matters
The retailer's guidance cut shows how a cyberattack can ripple from technology outages into revenue and profit targets. The impact spans both its European and U.S. operations.
The company estimates a revenue hit of 200 to 250 million euros and an operating profit reduction of 75 to 100 million euros, with an operating margin nearing 4%. Details on how long recovery will take beyond the initial week of paralysis remain unclear.
The players
Ahold Delhaize
A multinational grocery retail group headquartered in the Netherlands that operates supermarket chains across Europe and the United States.
The details
Ahold Delhaize's IT systems were paralyzed for more than a week in October, prompting the preventive takedown of online stores and apps in Europe and the U.S. The retailer performed slightly better than expected in Europe and slightly worse in the U.S. in the third quarter.
Timeline
October 2026: Cyberattack paralyzes IT systems for more than a week.
Mid-October 2026: Online stores and apps taken down preventively in Europe and the U.S.
Third quarter 2026: Results slightly better in Europe, slightly worse in the U.S.
November 4, 2026: Full-year forecasts lowered following the cyberattack.
Big Picture
The preventive shutdown of online channels mirrors a pattern in which large retailers isolate systems to contain attacks, at the cost of short-term sales. The episode illustrates how that containment trade-off can translate directly into lowered annual guidance.
Shoppers who rely on online ordering and grocery apps may have faced interruptions during the outage in Europe and the U.S. Customers of similar chains should expect that digital ordering can become unavailable when retailers take systems offline to contain threats.
The takeaway
Retailers that depend heavily on digital channels face a direct trade-off between containing a cyberattack and maintaining sales. Shoppers may see service gaps when that containment step is taken.
