EXHIBIT 99.1 PRESS RELEASE DATED DECEMBER 23, 2002 GLATFELTER ANNOUNCES IMPLEMENTATION OF COST REDUCTION INITIATIVES York, Pa. (December 23, 2002) - Glatfelter has announced plans to implement cost reduction initiatives in its operations. Key action items of this operational plan include streamlining costs, realigning the organizational structure, and focusing on the cash flow of the operations. In conjunction with these cost reduction initiatives, there will be a 3% reduction in its workforce, including positions that were or will be eliminated by not filling vacant positions. "Continued weakness in the US economy, depressed pricing for our products and poor market conditions demand that we reassess our cost structure," said George H. Glatfelter II, Chairman and Chief Executive Officer. "We have adjusted spending levels across the board, but unfortunately, we cannot ignore the necessity of a reduction in force." The Company has targeted a workforce reduction of 76 positions. In January 2003, 40 employees at its U.S. operations will be directly impacted. The remaining 36 positions are expected to be absorbed by attrition and not filling already vacant positions. Costs associated with this workforce reduction are expected to be approximately $4.0 million, which will be recorded in the fourth quarter of 2002. These actions are expected to reduce 2003 operating costs by approximately $2.7 million and ongoing operating costs by approximately $3.6 million on an annualized basis. Headquartered in York, Pennsylvania, Glatfelter is a global manufacturer of specialty papers and engineered products. U.S. operations include facilities in Spring Grove, PA and Neenah, WI. International operations include facilities in Germany, France and the Philippines.
