American Woodmark Corp., a Winchester maker of wood cabinets, said sales jumped more than it had expected in its fourth quarter as more homeowners remodeled and housing starts remained strong.

Profit rose to $8.4 million ($1 per share) in the fourth quarter ended April 30, compared with $7.6 million (91 cents) the year before. Sales jumped 25 percent, to $180.4 million from $144.3 million.

For the year, though, profit fell to $31.7 million ($3.80), compared with $32.7 million ($3.89). The company blamed higher material costs, especially hardwood lumber and plywood, and employee benefit expenses.

Sales rose 18 percent, to $667.5 million from $563.5 million the year before.

* Smithfield Foods Inc., the world's largest hog producer and processor, said fourth-quarter profit rose 24-fold on soaring demand for pork -- thanks in part to the low-carbohydrate diet trend -- and the sale of a Canadian meat business.

Net income rose to $122.7 million ($1.09 a share) for the fourth quarter of the fiscal year ended May 2, from $5.1 million (5 cents) a year earlier. Revenue rose 46 percent, to $2.52 billion from $1.75 billion.

The Smithfield company bought the pork business of Farmland Industries Inc., the sixth-largest U.S. producer. Smithfield, the maker of John Morrell processed meats, became the largest U.S. producer of branded bacon as demand surged with the popularity of high-protein diets.

For the year, net income jumped to $227.1 million ($2.03) from $26.3 million (24 cents) a year earlier. Sales rose 30 percent, to $9.27 billion from $7.13 billion.

* Williams Industries Inc., Manassas bridge builder, swung to a profit of $119,000 (3 cents a share) during the third quarter of its fiscal year ended April 30, from a loss of $356,000 (10 cents). Revenue rose to $14.9 million from $12.2 million.

For the first nine months, the company lost $321,000 (9 cents) on revenue of $40.5 million, compared with a loss of $912,000 (25 cents) on revenue of $38.9 million.

Also, the company said it reached an agreement with the Virginia Department of Transportation over the Springfield Interchange project, a multimillion-dollar contract that Williams had considered rejecting because of increases in the cost of steel.
