EMC president and chief executive officer Joe Tucci said that sales were down because customers are "underspending their existing budgets, striving to balance expenses in order to offset their own revenue shortfalls".
Sales for EMC during the quarter, which ended 30 September, totalled $1.26bn (£0.8bn), a 4% increase over last year's third quarter, but a drop of 9% from the second quarter of 2002. The company reported net income of $21m (£14m) this quarter.
"As a result, we are taking further steps to align our costs with the realities of this painful economy," Tucci said.
Bill Teuber, EMC's chief financial officer, said the company would "extend" its cost reductions, which include laying off 1,350 employees, dropping its total number of workers to 17,000. EMC announced the latest layoffs earlier this month.
"We expect the majority of this reduction will be completed during the fourth quarter of 2002," Teuber said.
EMC has been focusing its attention on the midrange marketplace. In the past few months, it launched two arrays that will be sold by partner Dell Computer.
Salomon Smith Barney research analyst Clinton Vaughan said that EMC has gained share in the midrange market this quarter while losing ground on its high-end Symmetrix arrays "due to tempered demand in front of its upcoming Symmetrix 6 product launch".
Overall, EMC lost about 1.7% in market share quarter over quarter, while IBM and Hitachi each gained about 1%, Vaughan said.
"Both IBM and Hitachi recently launched new high-end storage products which gave them a boost in [the third quarter] after eroding/stalling their shares in [the first half of 2001]," Vaughan said.
