Overview
Chemtura was an American specialty chemicals company that supplied additives, intermediates, performance materials, and other formulation ingredients to industrial manufacturers. The company was headquartered in Philadelphia, Pennsylvania, and maintained another principal executive office in Middlebury, Connecticut. It operated manufacturing, research, logistics, sales, and administrative activities across North America, Latin America, Europe, and Asia, with production plants in 11 countries and approximately 2,500 employees before its acquisition by Lanxess. Chemtura's corporate lineage combined several older industrial and chemical businesses. Its immediate predecessor, Crompton & Knowles Corporation, was incorporated in Massachusetts in 1900 and entered specialty chemicals manufacturing in the 1950s. The wider lineage reached back to nineteenth-century textile-machinery companies, including Crompton Loom Works and Knowles Loom Works, as well as the rubber and chemicals businesses that later became associated with Uniroyal. In 1996, Uniroyal Chemical Corporation merged with Crompton & Knowles. A further merger with Witco Corporation in 1999 created Crompton Corporation. Crompton's 2005 acquisition of Great Lakes Chemical Company produced Chemtura Corporation, with Great Lakes Chemical continuing as a subsidiary. The company organized its operations into two principal reporting segments. Industrial Performance Products included synthetic lubricants and greases, synthetic base stocks, lubricant additives, and urethanes. Industrial Engineered Products included brominated performance products, flame retardants, fumigants, and organometallic specialties. These materials were sold mainly business-to-business for use in automotive and transportation products, lubricants, plastics, construction materials, electronics, packaging, and other durable and nondurable goods. Chemtura expanded and reshaped its portfolio through acquisitions, divestitures, and asset transactions. It acquired Kaufman Holdings in 2007 and purchased bromine and bromine-chemical assets from Solaris ChemTech and Avantha Holdings in 2012. It also consolidated its ownership of DayStar Materials in 2013. During the same period, the company sold its antioxidant business to SK Blue Holdings and Addivant, divested its consumer-products operations, including BioLab, to KIK Custom Products, and sold Chemtura AgroSolutions to Platform Specialty Products. These transactions narrowed the business toward industrial performance and engineered chemicals. Chemtura entered debtor-in-possession proceedings under the protection of the United States Bankruptcy Court for the Southern District of New York in March 2009 and emerged from that process in November 2010. In later years it reported global core-segment revenue of $1.61 billion for 2015. The company was led by Craig A. Rogerson as chairman, president, and chief executive officer during the period described in the reference material. In September 2016, Chemtura accepted an all-cash acquisition offer from Germany's Lanxess AG. Following regulatory clearance and shareholder approval, Lanxess completed the acquisition on April 21, 2017. The transaction was reported as a $2.1 billion cash acquisition, and Lanxess absorbed Chemtura's employees and sites. Chemtura therefore ceased to operate as an independent company, with its former businesses and locations becoming part of Lanxess.
History
Chemtura Corporation emerged from a group of textile, rubber, and chemical businesses whose roots extended into the nineteenth century. Crompton Loom Works and Knowles Loom Works were major textile-machinery companies in Worcester, Massachusetts, and merged in 1879. Another part of the lineage came through the rubber industry, including businesses associated with the United States Rubber Company and Uniroyal. Uniroyal Chemical Company was formed in 1986, acquired by Uniroyal Chemical Corporation investors in 1989, and became a public company before merging with Crompton & Knowles Corporation in 1996. Crompton & Knowles had been incorporated in Massachusetts in 1900 and began specialty chemicals manufacturing in 1954. Its merger with Witco Corporation in 1999 formed Crompton Corporation. In 2005, Crompton acquired Great Lakes Chemical Company, creating Chemtura Corporation. Great Lakes Chemical remained a subsidiary and became central to Chemtura's bromine, flame-retardant, and engineered-products activities. Chemtura developed as a global supplier to industrial manufacturers rather than as a consumer-facing chemical brand. Its materials were used as additives, ingredients, and intermediates in transportation, automotive, energy, electronics, construction, packaging, plastics, and lubricant applications. The business was divided into Industrial Performance Products and Industrial Engineered Products. The first segment covered synthetic lubricants, greases, base stocks, lubricant additives, and urethanes. The second covered brominated performance products, flame retardants, fumigants, and organometallic specialties. The company pursued both expansion and portfolio simplification. It completed the acquisition of Kaufman Holdings in 2007. In 2009 it entered debtor-in-possession proceedings in the United States Bankruptcy Court for the Southern District of New York, remaining under court protection until November 2010. In 2012 it agreed to acquire bromine and bromine-chemical assets from Solaris ChemTech Industries and Avantha Holdings. In 2013 it bought the remaining interest in DayStar Materials, while also selling its antioxidant business to SK Blue Holdings and Addivant and its consumer-products business, including BioLab, to KIK Custom Products. In 2014, Chemtura agreed to sell Chemtura AgroSolutions to Platform Specialty Products. The sale closed later that year and removed a major agricultural-chemicals activity from the portfolio. Chemtura subsequently concentrated on industrial performance and engineered chemicals. The company reported global core-segment revenue of $1.61 billion for 2015 and operated plants in 11 countries, with activities across the Americas, Europe, and Asia. Chemtura also faced legal and regulatory controversy over brominated flame retardants, particularly Firemaster 550, a product marketed for use in polyurethane foam in upholstered furniture. Investigative reporting and cited research raised questions about potential human exposure and health effects. California's effort to revise furniture flammability standards led Chemtura to file lawsuits in 2013 and 2014. California ultimately adopted revised standards and later required labeling concerning toxic flame-retardant chemicals. In September 2016, Chemtura accepted Lanxess AG's all-cash acquisition offer. U.S. antitrust approval followed in December, and shareholders approved the transaction in February 2017. Lanxess completed the acquisition on April 21, 2017, reportedly paying $2.1 billion in cash and absorbing approximately 2,500 employees at 20 sites in 11 countries. Chemtura thereafter ceased to exist as an independent corporation.
