Blackpool Pleasure Beach made a bottom-line loss of £524,000 for the financial year ending April 2012.
The Holdings – which includes the amusement park, Big Blue hotel and the South Shore Mutual Insurance Company – suffered the loss despite revenue actually increasing by 7% on last year.
The figures are the first released to include the introduction of the Nickelodeon Land themed area and its new rides in 2011.
A profit of more than £300,000 was recorded in the previous financial year.
Managing director Amanda Thompson said: “Since weather during the key 2011 season was materially worse than that of the 2010 season, this is considered to be the main reason for the shortfall in sales compared to budget.”
TheBusinessDesk.com website reports that a cost-cutting exercise is currently underway, and the company expects to make an even heavier loss for the current financial year.
It is widely expected that some of the less popular attractions are to remain closed during the 2013 season, which begins initially on weekends starting 9 February.
Pleasure Beach has not released visitor numbers since free admission under a pay-per-ride basis was removed in 2009.
