For 41 years, CERAC has proudly built relationships with all of you based on strong commitments to quality, integrity, safety, and community and environmental stewardship. This tradition of pride and commitment continues as CERAC enters into a new era.

We are pleased to announce that CERAC has been acquired by Williams Advanced Materials Inc. (WAM) of Buffalo, NY, a subsidiary of publicly held Brush Engineered Materials Inc. (NYSE: BW). CERAC will operate as a wholly owned subsidiary of WAM, continuing to manufacture specialty inorganic chemicals and thin film materials under the CERAC name at our facility in Milwaukee, WI. The experienced and dedicated CERAC workforce also remains in place, so your contacts at CERAC will not change. Bart Ott, CERAC's former V.P. of Sales and Marketing, has been appointed V.P and General Manager.

CERAC and WAM have worked together in a reciprocal customer-supplier relationship for many years, and combining our products, services and resources offers many advantages. Both companies have extensive experience in the thin film industry, each leaders in the markets they serve. Our customers and suppliers will benefit from a broader product line, new deposition services, access to expanded technical knowledge and added global sales and service channels. Our continuous improvement efforts and community interests will be strengthened with added resources available for technology and facility upgrades.
