At a staff briefing yesterday, the group said that the national newspaper division Guardian News & Media (GNM) is expected to announce a loss of £35m in the year to the end of March 2009.
In line with the rest of the publishing industry, GNM display advertising revenues fell 30% year-on-year during the past financial year.
GMG Regional Media, the company's regional newspaper publisher, is expected to make a profit, albeit less than £1m, down on the £14.3m profit made in 2008.
Elsewhere, the group's other ventures had slightly more positive news – publishing and events company Emap, in which the Guardian has a 30% stake, will announce a £100m profit, as will Trader Media Group, of which GMG is the majority owner.
However, money from both businesses will go towards paying off debts rather than being passed back to GMG.
According the website, chief executive Carolyn McCall told staff the company had "exchanged short-term profit for long-term security" with the Trader Media Group and Emap.
The group's full results will be announced in August.
