LONDON, Nov 9 (Reuters) - British discount retailer B&M on Thursday raised its full-year profit guidance as it reported a 16.1% rise in first half core earnings, saying it has strong trading momentum.

B&M, which sells everything from toys to frozen food and garden furniture and has a bigger market capitalisation than Marks & Spencer, said it now expected 2023/24 adjusted EBITDA of 620-630 million pounds ($761-$774 million), up from 573 million pounds made in 2022/23.

It was previously forecasting the 2023/24 outcome would be higher than 2022/23's.

For the first half to Sept. 23, adjusted EBITDA was 269 million pounds, with revenue up 10.4% to 2.55 billion pounds as B&M's products and prices chimed with consumers in an ongoing cost of living crisis. ($1 = 0.8142 pounds) (Reporting by James Davey; editing by Sarah Young)
