The broadcaster is expected to announce, along with its results, that it is to cut its shareholder dividend as it feels the effects of the slowdown in advertising revenues.
Merrill Lynch analyst Neil Blackley warned yesterday that ITV's revenues could be down 10%-15% on last year, confirming fears that the advertising market is slowing more than anticipated.
The results are also expected to show the impact of the loss of revenues from last month's sale of film-imaging business Technicolor to France's Thomson Multimedia. The business generates around £150m a year in operating profits.
The broadcaster has also increased spending on its joint-venture digital offering ONdigital, which is undergoing an aggressive rebranding and restructuring. The service is to be relaunched as ITV Digital.
Analysts had forecast that the advertising market would stabilise in July at around the same figure as the comparable period last year. ITV's problems, however, look set to continue until September, along with its declining audience.
The broadcaster is hoping to claw back some of its audience share with a raft of new programmes including reality TV show Survivor, which begins on Monday; and the Premier League football highlights
