British newspaper publisher Trinity Mirror said it expected an 11% fall in first-half revenue as print advertising markets continued to remain challenging.
The company owns the Daily Mirror and Sunday Mirror titles.
Print advertising revenue is expected to fall 19% in the period, said the company, which has been battling lower advertising rates at the Daily Mirror and Sunday Mirror.
Trinity Mirror said it was targeting structural cost savings of £20m for the year, compared with the £10m it targeted in March.
The increased cost-savings target would add £5m to restructuring expenses, the company said.
