Like-for-like profits are expected to be 0.5% ahead of last year. "Our focus on offering value for money with high service standards in a quality pub environment is generating strong consumer appeal and maximising returns," the group said in a statement.Marston's Beer Company saw beer volumes rise 2% from last year, outperforming a declining market. "Our focus on localness and premium ales contributed to this growth with premium cask ale up 4%," Marston's explained. Net debt and cash flow are in line with company expectations.---CJ
