The retailer's out-of-town stores have struck a chord with consumers during the COVID-19 pandemic and its stores have been allowed to stay open through the restrictions because they also sell food.

Third-quarter sales rose to 1.40 billion pounds, from 1.14 billion pounds a year earlier.

The retailer, however, flagged uncertainties ahead as Britain headed into a fresh lockdown to fight a new variant of the novel coronavirus.

B&M narrowed its adjusted core profit forecast to a range of 540 million pounds to 570 million pounds for the year ending March 27, after it let go of 80 million pounds ($109 million) of property tax relief offered by the UK government in early December.

The move followed a similar decision by major supermarket groups after criticism from lawmakers and media for paying dividends while receiving the relief.

B&M said in December it expected core profit of 600-650 million pounds, but that figure did not include the impact of the 80 million pound business rate payment.

B&M said it would pay a special dividend of 20 pence per share, worth about 200 million pounds in total, towards the end of this month.
