Whole Foods ( WFMI), purveyor of organic food, announced after the closing bell Wednesday that it will buy out like-minded Wild Oats Markets ( OATS), propelling both stocks upward. Whole Foods will pay $18.50 a share for the Boulder, Colo., company, or about $565 million -- an ample premium to its $15.72 regular-session closing price.

Whole Foods posted income of $53.8 million, or 38 cents a share, in the period ended Jan. 14, down from last year's $58.3 million, or 40 cents a share. Same-store sales rose 7%, compared with a 13% climb the prior year, and total revenue grew 12% to $1.9 billion. Austin-based Whole Foods was trading up $2.23, or 4.9%, to $47.93. Wild Oats was surging $2.61, or 16.6%, to $18.33.

NCI ( NCIT) bounded past fourth-quarter expectations, reporting profits of $3.1 million, or 23 cents a share, on $64.6 million in revenue. Analysts polled by Thomson Financial were seeking 19 cents a share on $58.6 million. The Reston, Va., company, which sells information-technology services to the federal government, guided to the higher end of first-quarter expectations -- 18 cents to 20 cents a share on $58 million to $62 million in revenue. Full-year income should range from 83 cents to 88 cents a share -- at least a nickel above the mean target. Shares were adding $2.12, or 15.3%, to $16.

Marketing-services company ValueClick ( VCLK) said it earned $22.1 million, or 22 cents a share, on sales that shot up 38% year over year to $160.4 million. The Westlake Village, Calif., firm had a year-ago profit of $14.2 million, or 14 cents a share. Analysts were looking for 18 cents a share on revenue of $148.3 million. 2007 should bring in between $645 million and $665 million in sales, which more than covers the upper range of the consensus. Shares were bouncing $2.88, or 10.9%, to $29.35.

General Maritime ( GMR) declared a large one-time dividend of $15 a share in cash, wooing back investors after a regular-session dip caused by slightly subpar fourth-quarter results and a 13% decline in its quarterly dividend. The New York-based shipping company also announced it will now target a 50-cents-a-share dividend every quarter, with actual figures to be determined (at least in part) by the company's financials at the time. Shares were adding $3.63, or 9.1%, to $43.35.

Semiconductor Analog Devices ( ADI) slipped a penny below earnings targets in the first fiscal quarter, with operating income totaling $156.5 million, or 40 cents a share. Revenue, however, came to $691.6 million and flew past the $652 million consensus. Last year, the Northwood, Mass.-based company posted profits of $159.7 million, or 37 cents a share, on sales of $621.3 million. Shares were gaining $1.48, or 4.4%, to $34.80.

Winston Hotels ( WXH) shares rose on word it will be bought by Wilbur Acquisition for $14.10 a share. The deal should close in the second quarter. Shares of the Raleigh, N.C., real estate investment trust were up 35 cents, or 2.6%, to $14.06.

PGT ( PGTI) slumped after it swung to a surprise fourth-quarter loss of $1.3 million (adjusted), or a nickel a share. The Street had projected a dime-a-share profit. Sales also slid 22.6% from last year to $68.2 million, falling $15.6 million short of the mean estimate. The Florida-based company, which makes impact-resistant windows and doors, blames the poor results on the weakened state of the larger housing market, which is seeing less demand for new homes and, therefore, less need for PGT's products.

Chief Financial Officer Jeff Jackson said the company has lowered its operating expenses to match the current climate, and he believes it will "emerge even stronger when the housing cycle rebounds." Shares were off 65 cents, or 5.1%, to $12.02.

PDL BioPharma ( PDLI) said it earned $6.1 million (excluding items), or a nickel a share, in the fourth quarter, missing the 8-cent estimates and retreating a penny a share from last year. The Fremont, Calif., company expects 2007 earnings to range between 38 cents and 54 cents -- at least 10 cents below Wall Street projections. Shares were falling 74 cents, or 3.9%, to $18.40.
