On January 24, 2002, Agere Systems announced that it would be closing the Reading Works in 12 to 18 months. The planned changes involved closing the Breinigsville, Pennsylvania plant in Lehigh County, Pennsylvania, which was opened in 1988; selling the Orlando plant in Florida; and consolidating several locations in New Jersey. All operations were consolidated at the Allentown, Pennsylvania, headquarters location and the New Jersey locations. About 1,500 workers were transferred from Reading to Allentown where 3,200 workers were employed prior to the relocation. As Agere was leaving, Legerity, Inc., assumed some of the operations formerly done by the Muhlenberg plant in the old Building 10 on North 13th Street. In this facility Legerity assembled 40 former Agere circuit-design, physical-design, application-design and process development engineers to support the analog line card integrated circuit business it purchased from Agere. Legerity is a design facility that uses other companies foundries to manufacture its products. In May 2003, Agere Systems Inc. ended all manufacturing and began decommissioning its Muhlenberg Township plant. The last 346 manufacturing employees were laid off. About 50 employees — mostly maintenance — remained at the plant until a buyer was found.
