Electronics retailer Darty has issued a warning on its full-year profits.

The retailer said if conditions continue, “adjusted profit before tax for the year to April 30 is unlikely to meet the lower end of expectations”. Darty’s total revenue in the third quarter to January 31 fell 2.5%, and like-for-like sales slid 0.5%.

Activist investor Knight Vinke, which holds a 25% stake in Darty, has said it will exercise its contractual right to place a representative on Darty’s board immediately.
