Wausau Paper Announces Revised Earnings Estimate, Printing & Writing Downtime

MOSINEE, Wis.–(BUSINESS WIRE)–Dec. 21, 2005–Wausau Paper (NYSE:WPP) today announced revised fourth-quarter earnings guidance, primarily reflecting weaker-than-expected Printing & Writing results.

For the fourth quarter ending December 31, the Company is projecting losses of $0.13 – $0.15 per share, excluding timberland sales gains and charges related to the closure of its sulfite pulp mill in Brokaw, Wisconsin. The Company had earlier anticipated near-breakeven results on the same basis.

The majority of the earnings shortfall is attributable to further weakness in uncoated freesheet markets, reducing Printing & Writing segment sales and resulting in downtime at two of its three paper mills. Beginning December 24, the Company plans to take nine days of downtime at each of its Printing & Writing mills in Brokaw and Groveton, New Hampshire. Also contributing to the revised guidance are operating difficulties associated with the sulfite pulp mill closure at Brokaw and a $0.02 per share charge related to the disposal of two idle laminators at Specialty Products.

On a GAAP basis, fourth-quarter net losses of $0.20 – $0.23 per share are expected compared with third-quarter net losses of $0.18 per share.

“While disappointed with the performance of our Printing & Writing business, we remain optimistic about our long-term prospects,” said Thomas J. Howatt, president and CEO. “We continue to take a disciplined approach to managing our Printing & Writing business, taking approximately 18,000 tons of production downtime during the quarter. Printing & Writing results are expected to improve as the benefits of recently announced price increases and restructuring initiatives are fully realized.”
