Logica has warned investors that the boom in text messaging is slowing down.
In a generally upbeat trading statement, the British IT services company said that it expected to continue to achieve strong revenue growth and "continued margin improvement" this year.
However, it admitted that the slowdown in the mobile market would have an impact on the company.
"Our mobile networks business remains powerfully positioned globally and is by far the fastest growing business organically... however, we are not seeing the stellar growth rates of the recent past," said Andrew Given, Logica's finance director.
Given predicted that Logica's mobile networking business would continue to grow year-on-year.
Logica, a major supplier of text messaging software to the mobile industry, has benefited strongly from the explosion in SMS messaging.
