Shares of Merge Technologies ( MRGE) were among technology's losers Friday, tumbling 19% after the software company delayed the release of its fourth-quarter results and warned that sales for the period would be well below Wall Street's forecast.

The company, which does business as Merge Healthcare, expects to report fourth-quarter sales of $23 million to $26 million. Analysts polled by Thomson First Call project sales of $35.4 million. The company attributed the shortfall to certain large sales contracts signed during the fourth quarter that would be recorded as deferred revenue.

Merge blamed the delay in posting its full results on accounting issues surrounding fourth-quarter sales. "As a result of the complexities associated with accounting for sales transactions in the fourth quarter, our year-end audit has not been sufficiently completed and, accordingly, we are not publishing complete financial results at this time," the company said. Shares were trading down $4.55 to $19.95.

Syniverse ( SVR) sank 28% after the networking-services company posted in-line fourth-quarter earnings but projected first-quarter sales well below expectations. The company reported adjusted earnings of $14.8 million, or 22 cents a share, on sales of $83.6 million. Analysts expected earnings of 22 cents a share and sales of $83.9 million. A year earlier, the company recorded a loss of $3.9 million, or 10 cents a share, on sales of $88.3 million.

Looking ahead, Syniverse sees first-quarter earnings of $10 million to $12 million, before items, on sales of $71 million to $73 million. Analysts project earnings of $14.5 million, or 21 cents a share, and sales of $84.1 million. Shares were down $6.03 to $15.27.

Shares of Linktone ( LTON) rose modestly after the Chinese maker of wireless entertainment products announced the departure of its chief executive. The company didn't offer a specific reason for Raymond Yang's resignation, but said that Chief Financial Officer Colin Sung will serve as acting CEO until a permanent replacement is found. Yang's departure comes less than a month after the company slashed its fourth-quarter and full-year earnings guidance below Wall Street's expectation. Shares were trading up 9 cents to $7.10.

NetEase.com ( NTES) jumped 14% after the China-based Internet and wireless services company reported better-than-expected fourth-quarter results. The company earned $34.3 million, or 96 cents per American depository share, on sales of $60.4 million. Analysts expected earnings of 88 cents a share and sales of about $55 million. A year earlier, NetEase earned 45 cents a share and had sales of $33.6 million, according to First Call. Shares were up $10.46 to $85.96.

Shares of Marvell Technology ( MRVL) traded actively after the chipmaker posted better-than-expected fourth-quarter results. The company earned $97.5 million, or 30 cents a share, on sales of $489 million. Excluding items, the company earned $134.6 million, or 42 cents a share. Analysts expected earnings of 41 cents a share, before items, with sales of $485.8 million. During the year-earlier period, the company earned $54.9 million, or 18 cents a share, on sales of $340.3 million. Year-earlier adjusted earnings were $75.2 million, or 24 cents a share.

Marvell also announced a 2-for-1 stock split, subject to shareholder approval. If holders vote to increase Marvell's authorized share capital at the company's annual meeting in June, Marvell expects a stock split would take place within 30 days of the meeting. Shares were trading down 78 cents to $62.05 on volume of about 10 million shares, more than twice its normal daily volume.
