Excluding items, the San Jose, Calif.-based company earned $205.4 million, or 33 cents a share, on sales of $935.8 million. Analysts polled by Thomson First Call were expecting earnings of 34 cents a share on sales of $934.4 million. Looking ahead, eBay forecast first-quarter earnings of 34 cents to 35 cents a share, well below analysts' expectations of 40 cents a share. Sales, according to eBay, are expected to come in at $1.01 billion to $1.03 billion, below the $1.05 billion in sales that analysts had been expecting.

For the full year, eBay expects 2005 earnings of $1.48 to $1.52 a share on sales of $4.25 billion to $4.35 billion. Analysts had been expecting earnings of $1.61 a share on sales of $4.37 billion. Finally, eBay announced a 2-for-1 stock split, payable Feb. 16 to shareholders of record as of Jan. 31. Shares traded down $19.72 to $83.33 on volume of nearly 86 million shares, or almost nine times its daily average.

rose 21.8% after the company posted in-line third-quarter earnings on better-than-expected sales and said fourth-quarter sales would top forecasts. Excluding items, the software company posted a third-quarter profit of $16 million, or 21 cents a share, on sales of $108.6 million. Analysts were expecting earnings of 21 cents a share on sales of $106.8 million. A year ago the company earned $12.9 million, or 18 cents a share, on sales of $94.8 million. Looking ahead, Macromedia forecast fourth-quarter sales of $108 million to $113 million. Analysts had been expecting sales of $107.8 million. Macromedia said that fiscal 2006 sales would exceed $500 million, which is well above the $479.3 million that analysts had been expecting.

Separately, Macromedia announced the promotion of Stephen Elop to the position of CEO. He'll replace Rob Burgess, who served as CEO and chairman for the past eight years.

(SWKS) - Get Report

fell 4.4% after the chipmaker turned in mixed first-quarter results and warned that second-quarter sales would fall below analysts' expectations. Excluding items, second-quarter earnings came in at 13 cents a share, in line with expectations, on sales of $220.2 million, which fell slightly below expectations of $221.7 million. Looking ahead, Skyworks forecast second-quarter sales of $190 million. Analysts had been expecting sales of $210.8 million. Skyworks attributed the sales shortfall to a "one-time revenue impact" that relates to consignment inventory agreements with two of the company's largest customers.

Planar Systems

(PLNR)

fell 6.9% after the company's first-quarter earnings and sales fell below expectations. The flat-panel display maker posted break-even earnings on sales of $63.1 million. Analysts were expecting earnings of 3 cents a share on sales of $65.6 million. Looking ahead, Planar said second-quarter earnings and sales would be similar to just-completed first-quarter results. Analysts had been expecting a profit of 5 cents a share on sales of $67.2 million. "In the balance of fiscal 2005, profitability will continue to be constrained by planned, incremental increases in operating expenses to further penetrate European and Asian markets and to continue development of new software-rich products and services," the company said. Shares traded down 67 cents to $9.08.
