More Tech Firms Post Earnings Warnings

Will the earnings warnings ever stop?

Another batch of tech companies joined the chorus Monday. Among them:

* Mainframe software maker Compuware Corp. (CPWR) said it expects earnings in the range of 4 to 6 cents a share for the quarter, compared with 28 cents a share in the year-earlier period.

“In general, what appears to be happening in the mainframe marketplace is the demand for mainframe computing capacity appears to have slowed pretty dramatically,” said Damian Rinaldi, analyst at FAC Equities.

The stock slid 53 cents to a four-year low of $6.69 on Nasdaq.

* Storage Technology Corp. (STK), the No. 1 maker of corporate computer-tape storage systems, said third-quarter sales were hurt by a shortage of parts for its data-storage tape drives.

The company said it will report revenue of $465 million to $480 million for the quarter, down from $574 million a year earlier. The firm didn’t specifically comment on earnings.

The stock closed at $12.25 on the NYSE, up 6 cents in regular trading. The warning was made after the close.
