Incepta said that current indications do not show any evidence of significant improvement in the market, but assured investors that "gross revenues appear to be stabilising".
Shares in Incepta fell by 9.3% when the market opened this morning to trade at 19.5p.
Incepta, headed by executive chairman David Wright, has been hit by the drop in merger and acquisition activity -- a staple revenue provider in financial public relations. However, it said that its US technology PR business had returned to profitability, after being hard hit by the dotcom crash.
In a statement, the company said: "Our marketing services businesses continue to trade strongly and show growth, demonstrating their resilience in difficult markets.
"Our specialist financial advertising business continues to operate in weak markets and we have also recently seen weakness in our continental European corporate advertising businesses."
Incepta will publish its interim results on October 9.
