A spattering of after-hours earnings reports -- some strong, some disappointing -- moved several names after the market close Thursday.

Verigy ( VRGY) led the way, climbing some 11% after the maker of semiconductor-testing equipment swung to a profit in its fiscal second quarter and guided above estimates for the third.

The Singapore-based company reported non-GAAP earnings of $24 million, or 40 cents a share, on revenue of $183 million. Analysts were looking for EPS of 36 cents on sales of $176.2 million, according to Thomson First Call Data.

Looking ahead, Verigy expects to report net income in the third quarter of $27 million to $30 million, or 45 cents to 50 cents a share, on sales of $195 million to $205 million. Analysts are looking for 39 cents a share on $173.6 million in sales. Shares of Verigy were recently up $2.70 at $27.33.

Aruba Networks ( ARUN) also moved higher after swinging to a fiscal third-quarter profit, when the costs of stock-based warrants were discounted.

The wireless-periphals provider reported non-GAAP earnings of $1 million, or a penny a share, compared with a loss of $1.1 million, or 10 cents a share, last year. Sales rose 65% to $34.7 million. Analysts were looking for a loss of 4 cents a share. The stock was rising $1.03, or 6.8%, to $16.19.

Another winner was Red Robin Gourmet Burgers ( RRGB), which was lately rising 6.3% after reporting a slight rise in fiscal first-quarter profit. The Colorado-based restaurant chain reported earnings of $7.5 million, or 44 cents a share, including stock compensation expense. Last year the company reported $7.4 million, or 44 cents a share. Sales rose to $212.3 million from $170.5 million a year ago. The stock was lately $2.48 higher at $42.

Another after-hours climber was Citi Trends ( CTRN), which was lately rising 1.67% to $39, after the clothing retailer posted a penny-per-share beat in the fiscal first quarter and despite lowering its 2007 guidance.

Among those trading lower after hours was Peerless Systems ( PRLS), which was lately losing some 13% after the digital technology company swung to a first-quarter loss of $829,000, or 5 cents a share. Last year it generated net income of $2 million, or 11 cents a share. Sales fell to $4.7 million from $8.8 million a year ago. Shares were down 38 cents, at $22.50

Another swinging lower was Wave Systems ( WAVX), which was down 11 cents, or 4.4%, at $2.39 in after-hours trading. The computer-products maker will sell 7.3 million common shares for $2.05 each under a $25 million shelf statement and plans to use the net proceeds, roughly $14.2 million, to fund Wave's ongoing operations.
