Shares of

Acxiom

(ACXM)

were among the

Nasdaq's

losers Tuesday, falling 7% after the company warned that first-quarter results would fall short of Wall Street expectations.

The software company expects earnings of 6 cents a share on sales of $310 million. Analysts surveyed by Thomson First Call had been expecting earnings of 16 cents a share on sales of $324.2 million. The company said that its earnings were dragged down by sales erosion in Europe, which led to a reduction of about $4 million in profit compared with a year ago.

In an attempt to rein in costs, Acxiom said that it is in the process of an expense-reduction program that will result in the elimination of jobs in the U.S. and Europe. The job cuts are expected to reduce payroll costs by about 4%, or $16 million annually. In total, the company expects job cuts and other expense-reducing initiatives to result in savings of about $14 million to $16 million a quarter by the time the plan has been fully implemented, which is expected during the fourth quarter. Shares were trading down $1.34 to $20.17.
