Electronics group Philips is expected to reveal cost-cutting measures along with a fall in profits.
Phillips will report on a difficult quarter on Tuesday and may announce major restructuring in a bid to calm investors.
In March Philips joined other chipmakers in warning that the US economic slowdown and weaknesses in the telecoms sector would hit its profits.
The Dutch-based company says its chipmaking division will report disappointing first quarter figures, echoing similar warnings from competitors Intel and ASM Lithography.
Philips says like-for-like profits from its semiconductor division will drop by 10% in the first three months of 2001, although revenues will rise by 7%.
The company is expected to record a fall in first quarter net profits from continuing operations to between £127m and £230m, compared to around £704m last time.
Analysts believe Philips announce plans to cut-costs as the sector continues to suffer from problems in the US.
