Colruyt Shares Fall Nearly 10% After Profit Warning

Shares in Colruyt Group, Belgium’s largest supermarket retailer, slumped nearly 10% on the Brussels stock exchange on Thursday after the family-controlled company told shareholders it expects operating profit to decline in its 2026-2027 financial year. The warning, issued at the group’s annual general meeting in Halle on Wednesday evening, rattled investors already concerned about the retailer’s shrinking market share.

Intraday quotes showed Colruyt stock trading at €36.10, down 8.19%, by midday on Thursday, according to market data provider Trivano. The drop approached 10% at its widest, prompting La Libre Belgique to headline the move as a “near 10%” fall.

A Profit Warning After Years of Pressure

At the AGM on 30 September, Colruyt directors said operating result for the split financial year 2026-2027 would see “a slight decline compared with the previous financial year,” with the aim of “limiting this decline as much as possible,” as reported by Made in Vlaams-Brabant. The previous year’s operating result had been broadly stable at €465 million, while net profit fell 4.3% to €337 million.

The group attributed the deterioration to a mismatch between its cost base and its selling prices. “Because of low food inflation and higher general inflation, costs are increasing faster than revenue,” Colruyt said, pointing specifically to energy, logistics and staff costs driven by Belgium’s automatic wage indexation. As DHnet noted, the group expects the squeeze to be more pronounced in the second half of the year, producing an “asymmetric” profit profile.

Market Share Keeps Slipping

The profit warning landed alongside more unwelcome news on market share. The combined share of Colruyt, Okay and Spar slipped to 28.3% in the first five months of the new financial year (April to September), down from 28.5% for the whole of 2025-2026, according to RetailDetail. A year earlier the figure stood at 29%.

Colruyt blames a changing competitive dynamic, singling out the expansion of Sunday openings, longer trading hours and the scrapping of the compulsory rest day. “As a result, the combined market share of Colruyt, Okay and Spar is falling in the new financial year,” the company said. The erosion is widely attributed to the flagship Colruyt Laagste Prijzen chain, which generates the bulk of the group’s food revenue. The Okay convenience format began opening on Sunday mornings in early 2026, and the company says that move has since improved its position.

The Sunday-Opening Battle

The warning crystallises a structural problem Colruyt has flagged for over a year. At last year’s results presentation, the group reported that its combined market share had fallen to 28.5%, and warned its position would remain “under pressure” — a forecast that has now materialised, as VRT NWS reported.

CEO Stefan Goethaert has repeatedly argued that Colruyt competes on an uneven playing field. “We are the last fully Belgian retailer … we see that this gives us a competitive disadvantage, because our wage costs are higher,” he told VRT NWS in September 2025. Because Colruyt operates its Okay stores directly while rivals increasingly franchise their networks, he said, the wage-cost gap reaches around 30%, and on Sundays “the wage cost for us at Colruyt is even 300%. Simply unachievable.”

Goethaert renewed that call after this week’s AGM. “The differences between the joint committees and the increasing flexibilisation of the market call for a coherent framework that is workable for employees, companies and customers,” he said, according to RetailDetail. Trade unions have backed the push to simplify Belgium’s paritary-committee system.

Analyst Caution and a Familiar Pattern

The market reaction reflects both the substance of the warning and a history of sharp moves. Analyst consensus recommends holding the stock, with a median price target of €35.00 — slightly below Thursday’s share price, according to Trivano. The shares are down about 8% over the past month but up nearly 10% over the year.

This is not the first time a Colruyt profit warning has triggered a steep sell-off. In late September 2022, the stock fell more than 20% in a single day after a similar warning of a significant profit decline, illustrating how sensitive investors remain to the group’s thin margin model.

The group also faces a shifting portfolio. Carrefour and Intermarché have bid for Codifrance, Colruyt’s French wholesale subsidiary, in a move that would mark the retailer’s exit from France, while the sale of its stake in marine survey firm GEOxyz is expected to deliver a one-off gain of €25–30 million.

What to Watch

Colruyt’s AGM approved a gross dividend of €1.38 per share, payable from 6 October, and renewed board mandates for four years, including those of chairman Jef Colruyt and directors Wim and Lisa Colruyt. That continuity signals a family willing to ride out the storm — but the company’s near-term outlook remains clouded.

The key questions now are whether the second-half cost squeeze proves as severe as feared, whether the group can arrest its market-share decline as rivals keep extending opening hours, and whether Belgium’s fragmented wage-regulation system will finally be reformed in a way that narrows Colruyt’s structural cost disadvantage. For investors, the retailer’s famous “lowest price” guarantee has rarely looked so costly.
