Plum Creek Reports Results for Fourth Quarter and Full Year 2008

SEATTLE – Plum Creek Timber Company, Inc. (NYSE: PCL) today announced fourth quarter earnings of $95 million, or $0.57 per diluted share, on revenues of $461 million. Earnings for the fourth quarter of 2007 were $118 million, or $0.68 per diluted share, on revenues of $504 million.

Earnings for the fourth quarter of 2008 included an $11 million, $0.07 per diluted share, after-tax gain from the early retirement of debt and $3 million, $0.02 per diluted share, of severance costs primarily associated with the company’s plans to reduce manufacturing production. Earnings for the fourth quarter of 2007 included an after-tax gain of $43 million, or $0.25 per share, from the sale of nearly 100,000 acres of large, non-strategic timberlands in Wisconsin for approximately $70 million.

Earnings for 2008 were $233 million, or $1.37 per diluted share, on revenues of $1.61 billion. Earnings for the full year of 2007 were $282 million, or $1.61 per diluted share, on revenues of $1.68 billion.

Results for 2008 included the gain from the early retirement of debt, the severance costs, and the effect of a $6 million after-tax ($10 million pre-tax) impairment charge related to the company’s lumber manufacturing business recognized during the second quarter. The impairment charge reduced net income by $0.04 per diluted share. Results for the full year of 2007 included the income from the Wisconsin sale mentioned above.

“Plum Creek ended the year with a busy quarter,” said Rick Holley, president and chief executive officer. “We completed the formation of our Southern timberland joint venture, completed the first phase of the Montana conservation sale, retired more than $420 million of debt and repurchased over $200 million of common stock. We ended 2008 well positioned with a strong balance sheet and $370 million in cash. Our broad asset base diversifies our market risks and continues to provide excellent operational flexibility. We’re well positioned to weather the challenging economic times facing the country and expect to generate cash flow well beyond that required for our dividend.

“We are maintaining our value discipline. In 2009 we’ll continue to defer harvests in weak markets to protect value. Our value focus is evident in our Real Estate segment as well. We’ve removed listings from weak markets such as Florida and responded to attractive markets in other regions such as Mississippi. We’ve also made tough decisions in our manufacturing business, announcing the permanent closure of one sawmill and the curtailment of others.

“We’re not allowing the current state of the markets to distract us from our focus on developing long-term growth opportunities. These include growth of our non-timber natural resource business and our work aimed at serving emerging wood-based renewable energy markets.”

Summary of 2008 Results

Net income declined approximately 17 percent from 2007’s results as income from the company’s Resources and Manufacturing segments were impacted by the significant decline in residential construction and a weakening economy. Income from the balance of the company’s business segments was similar to 2007.

In the timber resource segments, the company’s results were affected by weak sawlog markets as lumber manufacturers reduced demand in light of very weak lumber pricing. The company reduced its total sawlog harvests 11 percent to their lowest recorded levels, choosing to allow a portion of the timber to grow rather than sell the trees into weak markets. Average sawlog prices were down 6 percent in the Northern Resources segment and 14 percent in the Southern Resources segment. Good demand for pulpwood from pulp and paper mill customers provided a modest offset to the difficult sawlog markets. Average pulpwood prices increased 15 percent in the Northern Resources segment and 17 percent in the Southern Resources segment. The company sustained its pulpwood harvest at elevated levels to take advantage of the attractive pricing.

In the Real Estate segment, the company reported income of $245 million during 2008 compared with $250 million during 2007. The 2008 results include $74 million of income from the conservation sale of approximately 130,000 acres of Montana timberlands to The Nature Conservancy and The Trust for Public Land. The balance of the income was generated from the sale of approximately 92,000 acres of lower-productivity timberlands and approximately 46,000 acres of recreation properties.

The company’s Manufacturing segment reported a $44 million loss for 2008 compared with a $2 million profit for 2007. The reported loss includes the impact of $10 million of asset impairments and $2 million of severance costs associated with production curtailments and a lumber mill closure. In addition, the company wrote down the value of purchased log commitments by $9 million, and wrote down log and finished goods inventories by $7 million.

The company continued to grow the contribution from its non-timber natural resources business, increasing operating income by $6 million, to a total of $23 million for 2008.

Review of Quarterly Operations

The Northern Resources segment reported fourth quarter operating profit of $8 million, compared with operating profit of $17 million reported in the fourth quarter of 2007. The decline in segment profits was driven primarily by a planned 20 percent reduction in sawlog harvest volume. During the quarter, the company limited its sawlog harvests in response to low sawlog prices and extended holiday downtime at lumber mills across the region. Average sawlog prices were approximately 5 percent lower than the same period of 2007. Good pulpwood demand in the northeast and lake states provided a modest offset to the difficult sawlog markets. Average pulpwood prices increased 16 percent compared with the fourth quarter of 2007, while the company’s pulpwood harvest was similar to the same period of 2007.

The Southern Resources segment reported fourth quarter operating profit of $25 million, compared with a $35 million operating profit reported during the fourth quarter of 2007. The decline in operating profit was primarily driven by lower harvest volumes compared with the same period of 2007. During the fourth quarter of 2008, the company contributed approximately 454,000 acres of timberlands to a venture with The Campbell Group. The company reduced its fourth quarter sawlog harvest approximately 380,000 tons, or 27 percent, from the same period of 2007. The lands contributed to the timberland venture accounted for 145,000 tons of the sawlog harvest in the prior-year period. The balance of the Southern sawlog harvest decline resulted from harvest deferrals as sawlog prices were 13 percent lower than the prior-year period. By contrast, pulpwood markets remained attractive, with pulpwood prices averaging 29 percent higher than the fourth quarter of 2007. The company reduced its fourth quarter pulpwood harvest by approximately 280,000 tons, or 14 percent, from the same period of 2007. The lands contributed to the timberland venture accounted for 130,000 tons of the pulpwood harvest in the prior-year period.

The Real Estate segment reported revenue of $215 million and operating profit of $104 million in the fourth quarter of 2008. These results include $150 million of revenue and $74 million of operating income from the Montana conservation sale mentioned above. The segment reported $198 million of revenue and $121 million of operating profit for the fourth quarter of 2007. The 2007 results included the $70 million large, non-strategic Wisconsin sale mentioned above.

During the fourth quarter, the company sold approximately 190,000 acres of land. These sales included the 130,000-acre conservation sale mentioned above. The company’s small, non-strategic timberland sales were concentrated in Michigan’s Upper Peninsula. The 47,000 acres of lands sold captured an average price of $750 per acre. Approximately 7,500 acres of recreation property sold at an average price of approximately $3,000 per acre.

The Manufacturing segment reported a $20 million loss for the fourth quarter of 2008, compared with a $1 million loss during the same period of 2007. These results include approximately $8 million of write-down for certain purchased log commitments and inventories, as well as approximately $2 million of severance costs related to the company’s

plans to reduce manufacturing production. Profitability in each manufacturing product line suffered as demand sharply declined during the fourth quarter. Sales volumes declined 19 percent for lumber, 40 percent for plywood and 47 percent for medium density fiberboard (MDF) products compared with the same period of 2007. Average prices declined 10 percent for lumber and 4 percent for plywood products compared with the same period of 2007. MDF prices increased approximately 16 percent over the past year, as increases in raw material costs drove MDF prices higher.

Formation of Southern Timberland Venture

On October 1, the company completed the formation of a previously announced timberland venture with The Campbell Group LLC. The transaction valued approximately 454,000 acres of Southern timberlands contributed into the venture by Plum Creek, at $1,725 per acre.

Also on October 1, the company received $783 million from the venture in the form of a loan. The interest on the loan is largely offset by the receipt of preferred dividends from the timberland venture. The company utilized a portion of these funds to retire existing debt and repurchase common stock during the fourth quarter.

Principal Repayment and Early Debt Retirement

During the quarter the company retired a total of approximately $421 million in debt as follows:

• Paid down $201 million on the line of credit;

• Retired $100 million private-placement debt that matured during the quarter as scheduled;

• Pre-paid $58 million of private debt at par;

• Executed open-market purchases of its publicly traded bonds. Bonds with a face value of $62 million were redeemed for $50 million. The bonds carried a coupon of 5.875 percent and were scheduled to mature in 2015. As a result, the company recorded an $11 million gain on the early extinguishment of debt during the fourth quarter.

Share Repurchases

During the fourth quarter, the company repurchased approximately $213 million, or approximately 5.6 million shares, of common stock at an average price of $38.15 per share.

For the full year, the company reduced total shares outstanding by approximately 3.7 percent. In total, the company repurchased $264 million, or 6.9 million shares, of common stock at an average price of approximately $38.53 per share. As of Dec. 31, 2008, the company had approximately 166 million shares outstanding and $137 million remaining under its current repurchase authorization.

Outlook

“Our long-term planning is at the heart of our strategies designed to protect and create shareholder value,” continued Holley. “Our operating plans for 2009 take into consideration the difficult market conditions we are likely to face for most of this year, as well as our positive long-term view of timber and rural land markets.”

Over the past year, lumber customers serving residential construction markets continued to reduce production in light of the unprecedented low level of residential construction activity. Recent industry reports estimate that U.S. lumber mills are operating at approximately 60 percent of capacity and recent lumber prices have reached levels not seen since the 1980s. The company anticipates that residential construction markets will remain very weak for most of 2009, and expects sawlog customers to remain extremely cautious.

While sawlog markets have been weak for the past year, pulpwood markets remained attractive throughout the year. Pulp and paper manufacturers sought pulpwood to replace a dwindling supply of residual chips from lumber mills. However, as the broader economic downturn accelerated during the fourth quarter of 2008, paper mills have reduced production and the prospects for continued strong pulpwood demand from this customer group has moderated.

Taking these conditions into consideration, the company expects to harvest between 16 million and 17 million tons of timber during 2009. The company expects to reduce sawlog production in both its Northern Resource and Southern Resource segments during 2009, deferring some harvest due to expected weak pricing. In late 2006, the company increased the pace of its forest thinning, particularly in the South, bringing to market previously deferred pulpwood volume in response to attractive pulpwood pricing and increased demand. The company maintained this pace throughout 2007 and 2008 as demand remained strong and pulpwood prices continued to rise. During 2009, the company plans to reduce the pace of its Southern pulpwood harvest to approximately 5.8 million tons, a level consistent with its long-term harvest plans.

The company expects Real Estate segment sales for the year to be between $430 million and $460 million. The company expects to close on the $250 million second phase of its three-phase conservation sale, in Montana during the first quarter. As a result, Real Estate segment sales are expected to be between $265 million and $275 million during the first quarter.

On January 8, the company announced its plans to curtail production in its manufacturing operations in order to match production with customer orders. As a result, the company expects the segment to narrow its losses during 2009 and provide cash flow neutral performance.

Reflecting all of these factors, the company expects 2009 earnings to be between $1.38 and $1.63 per share. The company anticipates first quarter earnings will be between $0.94 and $0.99 per share.

“Looking ahead in 2009, we are planning conservatively and do not expect meaningful near-term improvement in the economy or in our land and timber markets. Our approach in 2009 will be to further capitalize on our ability to exercise operational flexibility. We have a strong balance sheet and are responding appropriately to market conditions, ready to move quickly when markets show improvement. Our asset diversification, financial capability and strategic focus have Plum Creek well positioned to benefit from the opportunities that lie ahead,” concluded Holley.
