                Potlatch Reports Third Quarter Results

    SPOKANE, Wash.--(BUSINESS WIRE)--Oct. 25, 2007--Potlatch
Corporation (NYSE:PCH) today reported financial results for the third
quarter ended September 30, 2007.

    Q3 2007 FINANCIAL SUMMARY

- -- Earnings from continuing operations for the quarter were $41.2
    million, or $1.04 per diluted common share, compared to $31.1
    million, or $0.80 per diluted common share for the third quarter
    of 2006.

- -- Net earnings for the quarter were $41.0 million, or $1.04 per
    diluted common share, compared to $25.7 million, or $0.66 per
    diluted common share for the third quarter of 2006.

   -- Included in net earnings were net losses of $0.2 million and
       $5.4 million for the third quarters of 2007 and 2006,
       respectively, related to the company's former hybrid poplar
       tree farm, which are classified as discontinued operations in
       the Statements of Operations and Comprehensive Income. The tree
       farm was sold in the first half of 2007.

- --  Cash provided by operating activities from continuing operations
     for the nine months ended September 30, 2007, was $125.1 million.

    "During the third quarter, our Resource segment continued to
benefit from selling additional volume at improved pricing, compared
to 2006 when we partially curtailed harvest levels due to poor log
markets. Improved markets in the southern region, particularly for
pulpwood, and increased harvest levels in both the northern and
southern regions also helped to build a strong quarter for the
segment," said Michael J. Covey, chairman, president and chief
executive officer.

    "Potlatch is on course to achieve our goal of selling
15,000-20,000 acres of non-strategic land by year end. In conjunction
with the purchase of 179,000 acres in Idaho, we have cued up all
planned land sales to match as many closings as possible with 1031
like-kind exchange opportunities.

    "Pulp and Paperboard results remained very strong throughout the
third quarter. Paperboard pricing in the high-end folding carton
segment that we serve was strong due to very high operating rates and
the weak U.S. dollar. We had outstanding operating performance during
the quarter at both paperboard mills.

    "During the quarter, our Consumer Products segment experienced
record converting production and finished goods sales. These
production improvements helped to offset the continued high cost of
pulp for the segment.

    "Although we faced a continued slump in housing and weak lumber
pricing, we continued to generate positive income and cash flow from
our Wood Products segment, mainly due to our positioning in industrial
and specialty niche markets, including cedar siding and decking,"
concluded Mr. Covey.

    THIRD QUARTER 2007 BUSINESS PERFORMANCE

    Resource

 -- Operating income for the segment was $38.2 million, compared to
     $24.8 million earned in the third quarter of 2006.

 -- During the third quarter, Potlatch announced the acquisition of
     179,000 acres of timberland in central Idaho.

     --  The purchase price was approximately $215 million, or roughly
          $1,200 per acre.

     --  The acquisition is being made in two phases, the first of
          which involved the majority of the timberlands and closed in
          September 2007. The acquisition of the remaining lands is
          expected to close in January 2008.

     --  The acquired land is located in the heart of the central
          Idaho outdoor recreational corridor. It consists of stocked
          forests of ponderosa pine and mixed fir that complement
          Potlatch's core timberland base. In addition, the company
          believes that the acreage has exceptional recreational
          amenities and real estate value.

 -- Potlatch continued to capitalize on improving markets in the
     southern region and sold more volume compared to 2006, when
     harvest levels were partially curtailed due to poor market
     conditions.

     --  Fee harvest levels in the southern region increased 77
          percent in the quarter compared to the third quarter of
          2006, and increased 4.9 percent compared to the second
          quarter of 2007.

     --  Overall sales prices rose 37.5 percent compared to the third
          quarter of 2006, and 4.8 percent compared to the second
          quarter of 2007, primarily due to strong pulpwood markets.

 -- Harvest levels in the northern region were up overall compared to
     the same period last year. The primary reasons for the better
     performance were increased harvest levels in Idaho and harvested
     timber from the Wisconsin timberland, which Potlatch acquired
     earlier this year.

     --  Fee harvest in the northern region increased 31 percent over
          the third quarter of 2006 and rose 83 percent over second
          quarter 2007 levels, primarily due to normal seasonal
          logging curtailments in the second quarter.

     --  Prices declined 4.7 percent compared to the third quarter of
          2006 due to general market price erosion in Minnesota,
          however, prices rose 3.8 percent in the northern region
          compared to second quarter 2007.

    Real Estate

    (formerly known as Land Sales and Development)

- -- Operating income for the segment was $2.4 million, compared with
    $0.8 million for the third quarter of 2006. The improved results
    were attributable primarily to the sale of more acres of non-
    strategic lands.

- -- During the third quarter, Potlatch deferred approximately $1
    million in built-in-gain taxes from REIT land sales by using
    forward and reverse 1031 exchanges within the allowable periods,
    such as the purchase of the central Idaho timberland.

    Upon completion of the acquisition in central Idaho, Potlatch will
own approximately 1.7 million acres of timberland in the U.S. In
accordance with its intensive land value stratification process,
announced in December 2006, the company intends to stratify the newly
acquired central Idaho acreage into core timberland for growing
merchantable timber and non-core and higher and better use (HBU) lands
for real estate sales. Through the stratification process, Potlatch
has identified 250,000-300,000 acres over its entire ownership that
are non-strategic to its core forestland operations and which the
company expects to sell over the next 10 years.

    Wood Products

- -- Operating income for the segment was $2.4 million, compared to an
    operating loss of $5.2 million for the third quarter of 2006.

- -- Lumber results continued to be positively impacted by strong sales
    of inland red cedar.

- -- Improved operating efficiencies at the company's lumber facilities
    helped to lower conversion costs and increase production over the
    third quarter of 2006.

- -- Wood costs for the lumber operations were lower compared to last
    year's third quarter. Cedar log costs were higher, but the
    increase was more than offset by reduced costs for southern yellow
    pine sawlogs and mixed species sawlogs in Idaho.

    Pulp and Paperboard

- -- Operating income for the segment was $17.6 million, compared to
    $16.8 million for the third quarter of 2006.

- -- Market prices for both pulp and paperboard products increased in
    the third quarter compared to the same period in 2006. Pulp prices
    rose 12 percent and paperboard prices increased 4 percent compared
    to the third quarter of 2006.

- -- The weaker U.S. dollar and general global demand for pulp created
    the best global pulp market in approximately a decade.

- -- Exports of paperboard to Europe increased during the third quarter.

- -- The company's two paperboard mills, in Arkansas and Idaho, ran
    exceptionally well with near record production attained during the
    quarter.

   -- The Idaho mill's chip supply was ample during the quarter,
       resulting in an 8 percent reduction in pricing compared to the
       second quarter of 2007, but still 33 percent higher than the
       third quarter of 2006.

    Consumer Products (or "Tissue")

- -- Operating income for the segment was $5.1 million for the third
    quarter of 2007, compared to $6.2 million for the same period last
    year.

- -- Pulp prices increased by 14 percent, resulting in a $3.8 million
    negative cost impact for the third quarter compared to the same
    period last year.

    As the company continued to ramp up production at its midwest
converting facility, it has reduced less profitable parent roll sales
and reduced its midwest and total freight expenses. Despite the
increase in pulp costs, pricing of tissue products in the marketplace
remained very competitive, as additional competitive paper machine
tonnage has come on line and the company has been unable to increase
pricing without negatively impacting sales volume.

    Other Items

    In the third quarter of 2007, the company recorded an income tax
benefit of $2.6 million related to continuing operations. The income
tax benefit was the result of a favorable adjustment of $3.5 million
due to the final determination of amounts owed to the Internal Revenue
Service for the years 1995-2004. Excluding this benefit, the company
recorded an income tax provision of $0.9 million for the third quarter
of 2007, which was largely related to pre-tax income from the
company's taxable REIT subsidiary.

    Dividend Distribution

    During the third quarter, Potlatch paid a regular quarterly
distribution on the company's common stock of $0.49 per share.

    OUTLOOK

    "We believe we are well positioned through the balance of this
year to capture strong demand for rural recreational real estate and
we expect continued outstanding performance from our pulp and
paperboard segment. Log prices are expected to stay strong for cedar
and southern pulpwood, however, we do not expect a recovery in housing
starts or a bounce in lumber prices for several quarters," concluded
Mr. Covey.
