B&M European Value Retail SA (LSE:BME) shares fell 8.4% to 266.41p as the discounter sounded the alarm over profit this year and flagged the departure of chief executive Alex Russo.
Russo, who has been in charge since 2022, will leave at the end of April, with the process of recruiting a replacement in the “advanced stages”.
Adjusted pre-tax earnings were now guided to sit between £605 million and £625 million for its 2025 financial year, a statement said, down from £620 million to £650 million previously.
The FTSE 250-listed group said the lower profit guidance reflected “the current trading performance of the business, an uncertain economic outlook and the potential impact of exchange rate volatility”.
Chair Tiffany Hall hailed Russo for increasing the chain's store footprint in the UK and France and driving "a relentless focus on high operational standards and low costs".
The board has decided to allow him to remain eligible for an annual bonus for the current financial year and to retain his awards under the company's share plans.
