Centaur, which recently closed direct marketing title Precision Marketing, said trading in February has, to date, shown no signs of improvement.
The business-to-business publisher is due to report its half-year results next Thursday, 26 February, but has issued a trading statement saying: "We anticipate our performance for the year to June 2009 to be significantly below the Board's expectations."
However, the group added that "it is confident the fundamental strengths of the group remain unchanged".
The profit warning follows the closure of several titles at the group. Public Private Finance, Brand Strategy and Precision Marketing have closed.
The group has also overhauled Marketing Week, installing a new editorial team, and repositioned the title as a more features-based offering.
