Computer maker Dell may well be feeling competition from Apple, Acer and Lenovo, as the company expects sales to dip 7pc to US$14.9bn in the first quarter.
Analyst estimates had pegged sales for the period at an average of US$15.1bn, according to data compiled by Bloomberg.
Decreasing demand for PCs also affected growth.
Dell, however, reported a slight increase in revenue for its fourth fiscal quarter and full fiscal year 2012.
Revenue for Q4, which ended 3 February, amounted to US$16bn, up 2pc over the US$15.7bn from the same period in 2011. That 2pc sales increases is partly the result of an extra week in the fourth quarter of fiscal 2012 compared to the year-ago period.
Also for its fourth quarter, Dell reported earnings of US$764m, down 18pc over the US$927m from the same period last year. That amounts 43 cents per share, a decrease of 10pc compared to last year.
For the full fiscal year, Dell reported revenue of US$62.1bn, up 1pc compared to last year. The company also reported income of US$3.4bn, up 33pc over last year, with earnings per share rising during the period by 39pc to US$1.88.
