Shares of

Innodata Isogen

(INOD) - Get Report

were among technology's losers Wednesday, falling 26.1% after the company warned that fourth-quarter earnings results would fall below expectations.

The information management company said that earnings would be hurt by tax regulations that are expected to shave 1 cent to 2 cents from earnings during the quarter. As a result, the company forecast fourth-quarter earnings of 5 cents to 6 cents a share on sales of $13.3 million to $13.6 million. Analysts polled by Thomson First Call had been expecting earnings of 9 cents a share on sales of $14.3 million.

Separately, Innodata announced a 7.5 million-shares offering, of which existing shareholders will sell 3.25 million shares. Shares traded down $2.42 to $6.87.

Input/Output

(IO) - Get Report

fell 17% after the company warned that fourth-quarter earnings would be well below the low end of its previous earnings guidance. In October the company said it would earn between 8 cents and 14 cents a share. Input/Output blamed the shortfall on two transactions that didn't close during the quarter. The deals were in the company's original forecast and amounted to 10 cents a share in earnings and $10 million in sales. Analysts had been expecting earnings of 10 cents a share on sales of $88 million. Looking ahead, Input/Output forecast 2005 earnings of 15 cents to 40 cents a share. Analysts are expecting 41 cents a share. Shares traded down $1.41 to $6.90.

Shares of

Xilinx

(XLNX) - Get Report

fell 3.2% after the chipmaker lowered its third-quarter sales guidance. The company now expects a sequential decline of 11% to 12% during the quarter, instead of a drop of 5% to 8%, which it had originally forecast. The new forecast implies sales of $354.9 million to $358.9 million. Analysts had been expecting sales of $378.4 million. Xilinx said the lowered outlook was the result of "weaker-than-expected turns

orders placed and delivered within the quarter business in the month of December impacting all geographies." Full third-quarter results will be released on Jan. 20. Shares traded down 90 cents to $27.54.

LSI Logic

(LSI) - Get Report

rose 14.1% after the company raised its fourth-quarter sales outlook and said that it expects to turn a profit instead of post a loss. The chipmaker now expects sales of $415 million to $420 million, up significantly from its previous guidance of $360 million to $390 million. Excluding items, LSI now expects to post a fourth-quarter profit of 1 cent to 3 cents a share, compared with its previous guidance of a loss of 2 cents to 5 cents a share. "The growth of our storage and consumer businesses in the fourth quarter serves as a positive indicator that the inventory correction in the supply chain is substantially over in these two markets," the company said. Shares traded up 71 cents to $5.73.
