Cineworld shares fell 3.4%, or 7.25p to 202p after it said profits were almost flat as the World Cup drew Britons away from its cinemas.
Operating profit in the 26 weeks to July 1st fell to £14.8m, from £15.2m in the year-earlier period, the company said.
"We are pleased to announce good growth in first half revenues and EBITDA despite the impact of the World Cup which, as anticipated, resulted in a quiet June," chief executive Stephen Wiener said in a statement.
"The second half of the financial year has started strongly for the Group, with an excellent range of blockbusters and 3D films. The fourth quarter looks equally strong and brings an exciting line up of releases with titles such as "Wall Street: Money Never Sleeps" and "Little Fockers."
