Exhibit 99.1 WAUSAU PAPER REPORTS THIRD-QUARTER RESULTS, EXPANDED TIMBERLAND SALES PROGRAM MOSINEE, WIS...OCTOBER 24, 2005...Wausau Paper (NYSE:WPP) today reported a net loss for the third quarter of $9.0 million, or $0.18 per diluted share, compared to net earnings of $8.1 million, or $0.16 per diluted share, last year. Net sales rose 9 percent to $285.6 million, and shipments increased 7 percent to 229,000 tons. Third-quarter operating results included after-tax charges of $13.6 million, or $0.26 per diluted share, related to the previously announced closure of Printing & Writing's sulfite pulp mill in Brokaw, Wisconsin, and an after-tax gain of $0.7 million, or $0.01 per diluted share, from the sale of timberlands. For the first nine months, the Company reported a net loss of $9.7 million, or $0.19 per diluted share, compared with net earnings of $15.3 million, or $0.29 per diluted share, during the same period in 2004. In addition to sulfite pulp mill closure charges of $0.38 per diluted share, results for the first nine months included losses of $0.15 per diluted share at the Brainerd, Minnesota, paper mill; a gain on the sale of timberlands of $0.02 per diluted share, and stock incentive credits of $0.03 per diluted share. Prior-year results included stock incentive charges of $0.02 per diluted share. Net sales increased 6 percent to $828.7 million and shipments increased 3 percent to 672,000 tons. "Net sales and shipments increased to record levels in the third quarter despite soft demand in printing and specialty paper markets," said Thomas J. Howatt, president and CEO. "We continue to gain share in our target markets as recently introduced products - such as our new OptiServ (trademark) brand hands-free towel dispensing system - build in popularity with customers. Our progress in improving production efficiencies has been masked by sharply higher energy-related costs - most notably natural gas, transportation, and fuel oil. In total, the Company's energy-related costs increased the equivalent of $0.03 per diluted share in September compared with August, in large part because of the production and supply disruptions caused by Hurricane Katrina. In the third quarter, energy-related prices were approximately $0.06 per diluted share higher than last year." Specialty Products reported third-quarter operating profits of $4.3 million, compared with $6.3 million last year. Current-quarter results included a $1.0 million gain from the sale of timberlands. Net sales increased 1 percent while shipments declined slightly. "Third-quarter revenues increased despite highly competitive specialty markets and a continued decline in paper mill packaging volumes," commented Mr. Howatt. "Sales mix improvements, productivity gains, and somewhat lower fiber prices only partially offset higher manufacturing costs, including energy and transportation." Printing & Writing reported third-quarter operating losses of $23.1 million, compared with operating profits of $4.0 million last year. Net sales and shipments increased 13 percent and 16 percent, respectively. Third-quarter results included pre-tax pulp mill closure charges of $20.8 million, consisting primarily of non-cash charges related to accelerated depreciation of long-lived assets. Results also included operating losses of $2.8 million at Brainerd, equal to $1.8 million, or $0.04 per diluted share on an after-tax basis, and a $0.2 million gain from the sale of timberlands. "Market conditions remain very weak with uncoated freesheet demand down 4 percent from a year ago. Chronically oversupplied markets continued to severely limit pricing leverage and our ability to pass through increased costs," Mr. Howatt stated. "Despite these conditions, Printing & Writing increased third-quarter sales and upgraded its sales mix with the introduction of Exact Ice (trademark) and Exact Digital (trademark) brand products. We remain focused on improving the long- term profitability of this business and further penetrating attractive niche markets by leveraging our strong brands and broad manufacturing capabilities." During the third quarter, Printing & Writing reduced production by approximately 5,000 tons, taking four days of downtime at Brainerd and nearly one month of downtime on a 50,000 ton-per-year paper machine at Brokaw, with the latter remaining temporarily idled. "These moves allow Printing & Writing to more closely match production capacity with current demand and optimize production efficiencies and distribution costs," said Mr. Howatt. Towel & Tissue's third-quarter operating profits increased 37 percent to a record $10.8 million from $7.9 million last year. Net sales and shipments also reached record levels, increasing 19 percent and 9 percent, respectively. "We are pleased with the continued growth - both revenue and operating profit - achieved by our Towel & Tissue business," Mr. Howatt commented. "Selling price increases and product mix improvements are continuing to drive profitability, offsetting increased energy and transportation costs." Commenting on the fourth quarter, Mr. Howatt said, "As we enter the seasonally slower fourth quarter, underlying business conditions remain strong for our Towel & Tissue business but particularly challenging in Specialty Products and Printing & Writing. Despite unsettled markets and significant cost pressures, we are actively pursuing our core strategies - product leadership, niche market focus, customer service, and operational excellence - to drive long-term success. In the short term, energy-related prices are expected to further pressure margins in the fourth quarter, increasing the equivalent of $0.10 per share compared with the third quarter. As a result, we expect near break-even results in the fourth quarter, excluding sulfite pulp mill charges and timberland sales gains." Discussing the Company's timberland sales program, Mr. Howatt said, "Nearly one-third of the timberlands the Company holds would have been used for pulpwood at Brokaw's sulfite pulp mill. With the fourth-quarter closure of that facility those lands are no longer strategic to our operations. As a result, we are expanding our previously announced timberland divestiture program to 42,000 acres from 12,000 acres, generating estimated after-tax earnings of $29 million, or $0.57 per share, over the next three to four years."

Pulp Mill Closure In July 2005, the Company announced plans to permanently close the sulfite pulp mill at its Brokaw, Wisconsin, facility. The pulp mill closure is expected to be substantially completed by the end of 2005 and will result in the elimination of approximately 60 jobs, or 11 percent of the facility's workforce. The related long-lived assets will be abandoned. The cost of sales for the three months and nine months ended September 30, 2005, as reflected in the Condensed Consolidated Statements of Operations, include $20.6 million and $29.9 million, respectively, in pre-tax charges for accelerated depreciation and an adjustment of pulp mill inventory to net realizable value. Pre-tax restructuring expense related to certain assets disposed as a direct result of the closure and other associated costs were $0.2 million and $0.4 million for the three months and nine months ended September 30, 2005, respectively. Additional pre- tax closure charges of approximately $12.1 million are expected to be recognized over the next three quarters, with $11.5 million in the fourth quarter of 2005, and $0.6 million in the first half of 2006. Note 3. Interim Segment Information The Company has reclassified certain prior-year interim segment information to conform to the 2005 presentation. The reclassification is the result of a reporting change, effective January 1, 2005, for two converting facilities from the Printing & Writing segment to the Specialty Products segment. The Company's operations are classified into three principal reportable segments: Specialty Products, Printing & Writing, and Towel & Tissue, each providing different products. Separate management of each segment is required because each business unit is subject to different marketing, production, and technology strategies. Specialty Products produces specialty papers at its manufacturing facilities in Rhinelander, Wisconsin; Mosinee, Wisconsin; and Jay, Maine. Specialty Products also includes two converting facilities that produce laminated roll wrap and related specialty finishing and packaging products. Printing & Writing produces a broad line of premium printing and writing grades at manufacturing facilities in Brokaw, Wisconsin; Groveton, New Hampshire; and Brainerd, Minnesota. Printing & Writing also includes a converting facility that converts printing and writing grades. Towel & Tissue produces a complete line of towel and tissue products that are marketed along with soap and dispensing systems for the "away-from-home market." Towel & Tissue operates a paper mill in Middletown, Ohio and a converting facility in Harrodsburg, Kentucky. Sales, operating profit, and asset information by segment is as follows: (in thousands, except ton data) SEPTEMBER 30, December 31, 2005 2004 Segment assets (Note 1) Specialty Products $337,423 $342,724 Printing & Writing 271,496 281,378 Towel & Tissue 174,852 171,080 Corporate & Unallocated* 50,270 87,052 $834,041 $882,234 Three Months Nine Months Ended September 30, Ended September 30, 2005 2004 2005 2004 Net sales external customers (unaudited) Specialty Products $115,461 $114,580 $347,806 $347,245 Printing & Writing 100,549 89,361 288,399 264,680 Towel & Tissue 69,614 58,487 192,451 166,427 $285,624 $262,428 $828,656 $778,352 Operating (loss) profit (unaudited) Specialty Products $ 4,260 $ 6,330 $12,029 $16,073 Printing & Writing (23,103) 3,998 (40,772) 5,603 Towel & Tissue 10,776 7,855 28,582 21,287 Corporate & Eliminations (3,125) (2,896) (7,130) (11,480) $ 11,192) $ 15,287 $ (7,291) $ 31,483 Depreciation, depletion and amortization (unaudited) Specialty Products $ 6,164 $ 6,240 $ 18,581 $ 18,824 Printing & Writing 24,752 3,834 36,176 11,600 Towel & Tissue 4,939 4,548 14,619 13,550 Corporate & Unallocated 296 308 867 878 $ 36,151 $ 14,930 $ 70,243 $ 44,852 Tons sold (unaudited) Specialty Products 101,385 101,547 306,577 317,886 Printing & Writing 84,194 72,287 244,765 218,380 Towel & Tissue 43,196 39,459 120,749 113,592 228,775 213,293 672,091 649,858 <FN> *Segment assets do not include intersegment accounts receivable, cash, deferred tax assets and certain other assets which are not identifiable with the segments. {00080674.TXT/1}
