International Paper Co.'s (IP) third-quarter profit more than doubled on a pre-tax credit, exceeding expectations, but the company still posted weakened sales as demand from its customers continued to struggle.

Chairman and Chief Executive John Faraci said in July that it appeared the worst of the economic downturn had passed, but the paper and packaging company last week shuttered three of its U.S. mills to cut capacity for freesheet paper by 19%, paperboard by 7% and containerboard by 12% in the face of waning demand. It also said it doesn't expect demand to return to 2008 levels "in the near future."

"At the end of the third quarter, we began to see some modest improvements in demand in some segments of our paper and packaging businesses," Faraci said Wednesday.

International Paper reported profit of $371 million, or 87 cents a share, up from $149 million, or 35 cents, a year earlier. Earnings from continuing operations, excluding items such as a $525 million pre-tax alternative fuel credit, were 37 cents a share compared with 84 cents a year earlier, when the company saw items including pre-tax charges of $107 million and $155 million.

Revenue fell 13% to $5.9 billion.

Analysts polled by Thomson Reuters recently forecast earnings of 24 cents a share on $5.89 billion in sales.

Gross margin rose to 36.5% from 24.3%.

The company's industrial packaging segment saw revenue fall 3.9%, its printing papers segment saw sales decline 18%, and its distribution segment saw revenues slide 20%.

Operating profit, which excludes items, more than quadrupled in industrial packaging, more than tripled in its printing papers segment and fell by 40% in its distribution segment.

Shares closed at $22.63 Tuesday and didn't trade premarket Wednesday. As of Tuesday's close, shares have nearly doubled this year.
