The leisure giant has suffered from a weak euro and lower numbers at Alton Towers after a crash on its Smiler rollercoaster left five people seriously injured last summer.
Helal Miah, investment research analyst at The Share Centre, said: “Merlin’s place in the top 100 could be at risk after a troubled year. The serious accident at Alton Towers last June continues to impact the group’s profitability, while it has also had to contend with a weak euro and a tough London market.”
The group, which runs 110 attractions in 23 countries, said last February that like-for-like sales at the group’s resort theme parks division, which includes Alton Towers, fell 12.4 per cent in the year to 26 December. Overall, pre-tax profits at Merlin edged 0.3 per cent higher to £250 million.
