LP Reports Third Quarter 2003 Profits

October 22, 2003

PORTLAND, Ore.--(BUSINESS WIRE)--Oct. 22, 2003--Louisiana-Pacific Corporation (LP) (NYSE:LPX) reported today third quarter net income of $124.5 million, or $1.17 per diluted share, on sales from continuing operations of $675 million. In the third quarter of 2002, LP's net income was $3.3 million, or $0.03 per diluted share, on sales from continuing operations of $415 million. For the first nine months of 2003, LP reported net income of $108.8 million, or $1.03 per diluted share, on sales from continuing operations of $1.6 billion compared to a net loss of $19.4 million, or $0.19 per diluted share, on sales from continuing operations of $1.2 billion for the first nine months of 2002.

For the third quarter of 2003, income from continuing operations was $109.9 million, or $1.03 per diluted share. In the third quarter of 2002, LP's income from continuing operations was $17.8 million, or $0.17 per diluted share. For the first nine months of 2003, income from continuing operations before cumulative effect of accounting principle was $120.8 million, or $1.14 per diluted share. For the first nine months of 2002, income from continuing operations before cumulative effect of accounting principle was $25.4 million, or $0.24 per diluted share.

"Strong demand for oriented strand board (OSB) panels had a tremendous impact on our results as pricing reached record levels. This demand has continued into the fourth quarter," said Mark A. Suwyn, LP's chairman & CEO. "With the added production of our Chambord, Quebec and Woodland, Maine mills, we set a new quarterly production record -- producing more than 1.45 billion square feet of OSB."

"We are wrapping up our divesture program. During the quarter, we sold more than $90 million of timberland and other assets. Also, we recently announced the sale of our remaining 463,000 acres of Texas timberland for approximately $290 million," Suwyn stated. "These funds will further enhance our liquidity and increase our financial flexibility."

Suwyn continued, "Once we complete the sale of the few remaining assets in the program, we expect to generate more than $750 million in total value (including cash, liquidation of working capital and reduction of liabilities) from this program for our shareholders."

   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
   taxes) 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.
