EXHIBIT 99 Contact: Johnna Freeman MCMS, Inc. (208) 898-2600 jfreeman@mcms.com MSL TO ACQUIRE MCMS San Jose, Calif. - September 18, 2001 - MCMS, Inc., a global leading electronics manufacturing services provider announced today that it has reached an agreement to sell substantially all of its operating assets to Manufacturers' Services Limited ("MSL"). MSL is also a global leading supplier in the electronics manufacturing services industry with headquarters in Concord, Massachusetts. Rick Rowe, Chief Executive Officer of MCMS, said, "MCMS is very pleased to have a company like MSL acquiring its business operations." He added "given MSL's size and strong global presence, I believe this proposed transaction offers great opportunities for MCMS's customers, employees, and suppliers." MSL President and Chief Operating Officer, Bob Donahue stated, "The acquisition of MCMS meets several of our long range strategic objectives, principally in gaining a presence in Mexico and also strengthening our West Coast and Asian operations. Also, MCMS adds depth in the area of optics and radio frequency technology while increasing the diversity of our customer portfolio." Simultaneously, MCMS announced that it, and its two U.S. subsidiaries, have voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware in Wilmington to implement the sale. During the bankruptcy process, MCMS will have the opportunity to consider other offers for the operating assets. The Chapter 11 cases do not involve MCMS's foreign subsidiaries with the exception of its Belgium subsidiary, which filed for Judicial Composition on September 5, 2001 under the applicable laws of Belgium. The terms and conditions of the definitive agreement entered into between MCMS and MSL relating to the asset sale, including a purchase price of approximately $43.5 million, subject to certain adjustments and the assumption of certain liabilities, will be described in the Form 8-K to be filed by MCMS with the Securities and Exchange Commission. MCMS also announced today that it has secured a commitment for Debtor-in-Possession (DIP) financing from a consortium of banks led by PNC Bank, subject to bankruptcy court approval. MCMS emphasized that during the voluntary restructuring and sale process, day-to-day operations will continue uninterrupted. MCMS believes that the financing package and the other court orders that MCMS is requesting will, among other things, provide ample funding to pay all amounts due to its employees, maintain all employee benefit plans, and maintain normalized business with its suppliers post-petition allowing uninterrupted manufacturing services to its customers. The closing of the sale is expected to occur in November 2001, subject to regulatory and Bankruptcy Court approval. ABOUT MCMS, INC.
