The share price of PC Mall fell on Thursday after the company disclosed its earnings per share fell 92 percent in the fourth quarter.

The online computer vendor based in Torrance had net earnings of $83,000, or 1 cent per share, in the last three months of 2009. For the fourth quarter of the previous year, it reported earnings of $984,000, or 7 cents per share.

Chairman Frank Khulusi blamed higher costs for the swoon.

“Price pressure resulted in a decline in our gross profit for the quarter,” he said in a statement. “The decline in gross profit, coupled with the investments we have continued to make to position ourselves for future growth, caused our operating income to decline. We remain cautiously optimistic about the demand environment going forward.”

Shares of PC Mall fell 44 cents, or 8 percent, to close at $4.85 on Thursday.
