Warehouse Group, the country's biggest listed retailer, cut its guidance on adjusted profit for the current financial year, blaming a squeeze on margins in recent months.
The retailer expects adjusted net profit of between $62 million and $66 million in the year ending July 27, down from a previous forecast of $70 million, it said in a statement.
Net profit will likely be about $80 million, in line with previous guidance.
"Margin pressures experienced in recent months" was to blame for the downgrade, the retailer said.
The profit warning comes a day after Briscoe Group, the home ware and sporting goods chain, boosted fourth-quarter earnings, and flagged annual profit would be at least 25 per cent higher than a year earlier.
