LP Reports Second Quarter 2003 Results

July 29, 2003

PORTLAND, Ore.--(BUSINESS WIRE)--July 29, 2003--Louisiana-Pacific Corporation (LP) (NYSE:LPX) today reported a second quarter net loss of $17.2 million, or $0.16 per diluted share, on sales of $479 million. In the second quarter of 2002, LP's net loss was $13.2 million, or $0.13 per diluted share, on sales of $432 million. For the first six months of 2003, LP reported a net loss of $15.7 million, or $0.15 per diluted share, on sales of $892 million compared to a net loss of $22.7 million, or $0.22 per diluted share, on sales of $822 million for the first six months of 2002. All sales figures are from continuing operations only.

For the second quarter of 2003, income from continuing operations was $8.9 million, or $0.09 per share. In the second quarter of 2002, income from continuing operations was $7.5 million, or $0.07 per diluted share. For the first six months of 2003, income from continuing operations before cumulative effect of accounting principle was $10.9 million, or $0.10 per share. For the first six months of 2002, income from continuing operations before cumulative effect of accounting principle was $7.6 million, or $0.07 per share.

"Our continuing businesses showed significant strength exiting the quarter. However, during the first two months, poor weather conditions disrupted construction activity and seasonal demand for building products. In late May and June, demand surged for oriented strand board, siding and engineered wood products. That momentum has continued to build into the third quarter," said Mark A. Suwyn, LP's chairman & CEO.

Suwyn continued, "In addition to poor weather conditions, our operations were negatively impacted by elevated costs, compared to second quarter 2002, in energy, other petroleum-based expenses, and wood costs, and the continued strengthening of the Canadian dollar.

"We are making excellent progress toward achieving the objectives of our divestiture program. During the second quarter, we sold approximately $110 million of timberland. Also, earlier this month we announced a definitive agreement to sell 465,000 acres of timberland, which represents the last significant portion of our timberland that was not under contract or sold," Suwyn stated. "We are on track to divest the remaining assets and generate more than $700 million in total value (including cash, liquidation of working capital and reduction of liabilities) from this program for our shareholders."

LP also announced today that it is moving its remaining lumber and interior decorative panel facilities to discontinued operations, reflecting its intent to divest or discontinue operating these facilities within the next year. LP has signed letters of intent with interested buyers for the majority of the facilities and expects to complete most of the transactions by the end of 2003. As a result of these actions, LP was required to evaluate these facilities for impairment based on expected net sales proceeds. Based on that evaluation, LP recorded impairment charges associated with certain of these planned divestitures and shutdowns during the second quarter.

At 11:00 a.m. EDT (8:00 a.m. PDT) today, LP will host a webcast on its second quarter 2003 financial results. To access the live webcast and accompanying presentation, visit www.lpcorp.com and go to the "Investor Relations" section from the main menu.

   Accounting standards require that the estimated effective income
   tax rate (based upon estimated annual amounts of taxable income and
   expense) by income component for the year be applied to year-to-
   date income or loss at the end of each quarter. The primary
   difference between the statutory rate (38%) on continuing
   operations and the calculated rate relates to permanent difference
   associated with certain inter-company debt which is denominated in
   Canadian dollars. The components and associated estimated effective
   income tax rates applied to each period are as follows:

6. Cumulative Effect of Change in Accounting Principles:

   LP adopted Statement of Financial Accounting Standards No. 143,
   "Accounting for Asset Retirement Obligations," as of January 1,
   2003. This statement addresses the retirement of long-lived assets
   and the associated retirement costs. Under this statement, we will
   record both an initial asset and a liability for the present value
   of estimated costs of legal obligations associated with the
   retirement of long-lived assets. These initial assets will be
   depreciated over the expected useful life of the asset. Upon
   adoption of this statement, we changed our accounting for landfill
   closures, reforestation obligations associated with certain timber
   licenses in Canada and other assets. Implementation of this
   standard resulted in income of $0.2 million (or $0.1 million after
   tax) recorded as a "cumulative effect of change in accounting
   principle" as of January 1, 2003.

   LP adopted Statement of Financial Accounting Standards No. 142,
   "Goodwill and other Intangible Assets," as of January 1, 2002. As
   of January 1, 2002, LP discontinued amortization of goodwill. LP
   has determined that $6.3 million of goodwill recorded in the
   Engineered Wood Products business was impaired as of January 1,
   2002, and this amount is recorded net of income tax effects as a
   "cumulative effect of change in accounting principle" as of January
   1, 2002.
