Overview
U.S. Sugar Corporation is a privately held agricultural company headquartered in Clewiston, Florida, at the southern end of Lake Okeechobee. Founded in 1931 by industrialist and philanthropist Charles Stewart Mott, the company was created from assets acquired from the failed Southern Sugar Company and became one of the central agricultural businesses in South Florida. Its core activity is the cultivation and processing of sugarcane, making it the largest sugarcane producer in the United States by volume according to the referenced encyclopedia material. The company has also operated in citrus, vegetables, cattle, and related agricultural and transportation activities. The company's principal landholdings and farming operations extend across more than 230,000 acres in Hendry, Glades, Martin, and Palm Beach counties. Its production base is concentrated in and around the Everglades Agricultural Area, where U.S. Sugar is one of the major participants commonly grouped with Florida Crystals and the Sugar Cane Growers Cooperative of Florida as South Florida's "Big Sugar." The company has been an important employer in the Glades region, with more than 2,500 employees cited in the reference material. U.S. Sugar's history reflects the changing economics and technology of American agriculture. It expanded processing capacity during the postwar period and opened the Bryant Sugar House in 1962. At the time, that mill was described as the world's largest and most advanced sugarcane-processing facility, with a nominal capacity of 5,000 tons of cane per day. When sugar prices weakened during the 1970s and food manufacturers increasingly adopted corn syrup, the company diversified into cattle, citrus, and vegetables. It acquired South Bay Growers in 1980, entering large-scale production of lettuce, celery, and other leafy vegetables, and began planting orange trees in the mid-1980s. The ownership structure also changed substantially. In 1983, U.S. Sugar established an employee stock ownership plan as part of a move to take the company private. The transaction involved substantial long-term borrowing and was challenged by some shareholders who believed the offer undervalued their shares. In October 1987, a tender offer for the remaining publicly held voting shares completed the privatization and reduced the company's public reporting obligations. Later disputes over the ESOP valuation and alleged outside acquisition offers led to litigation in 2008. The company has faced labor, technology, environmental, and public-policy controversies. Historical reference material states that U.S. Sugar was charged with slavery-related violations during the 1940s. In the 1990s, the adoption of mechanized cane harvesting displaced field workers, leading to a class action that was settled with a payment of more than $5 million in 1998. U.S. Sugar also closed or reduced some vegetable and sugar operations as businesses became unprofitable, including the closure of the Bryant mill in 2007. The company's land and water footprint has made it a major participant in Everglades restoration debates. In 2008, Florida proposed purchasing most of U.S. Sugar's land and manufacturing assets under the Comprehensive Everglades Restoration Plan. The proposal was later revised to retain some sugar operations. In 2010, U.S. Sugar sold 26,800 acres to the South Florida Water Management District for the River of Grass restoration project. Despite these transactions, the company remains an operating agribusiness centered on sugarcane, with additional production of refined sugar, sweet corn, oranges, and other agricultural products.
History
U.S. Sugar was established in 1931 after Charles Stewart Mott acquired agricultural and industrial assets near Clewiston, Florida, from the failed Southern Sugar Company. The new corporation became part of the rapid development of commercial sugarcane agriculture around Lake Okeechobee and ultimately developed into one of the largest sugarcane businesses in the United States. During the 1940s, the company faced charges described in reference material as slavery violations. The episode forms part of the difficult labor history of South Florida agriculture. Mott later transferred shares connected with the company to the Charles Stewart Mott Foundation. After the Tax Reform Act of 1969 restricted the percentage of a corporation that a private family foundation could hold, the foundation transferred a substantial block of shares to the Mott Children's Health Center, a charitable medical organization founded in Flint, Michigan. U.S. Sugar expanded its industrial base in 1962 with the opening of the Bryant Sugar House. Its stated processing capacity was 5,000 tons of sugarcane per day, making it a major facility by contemporary standards. Following the death of Charles Stewart Mott in 1973, his son C.S. Harding Mott became chairman. The company then responded to changing commodity economics. Sugar prices weakened during the 1970s, while food manufacturers increasingly used corn syrup, encouraging U.S. Sugar to diversify beyond sugarcane into cattle, citrus, and vegetables. In 1980, the company acquired South Bay Growers, a large vegetable producer associated with lettuce, celery, and other leafy vegetables. In the middle of the decade it began establishing orange groves. The diversification strategy later encountered financial pressure: most of South Bay Growers was closed in 1994 after repeated annual losses, although a salad-processing operation serving large restaurant customers continued while a new owner was sought. The company also closed a sugar mill in 2004 and ended operations at the Bryant mill in 2007. The ownership structure changed through an employee stock ownership plan formed in 1983. U.S. Sugar borrowed heavily to support the transaction, and some shareholders brought a class-action lawsuit because they believed the price offered for their shares was too low. In October 1987, the Mott-related ownership group and the employee plan offered to purchase the remaining voting shares held by public investors. The resulting transaction took the company private and reduced its reporting obligations. The move toward mechanized cane harvesting during the early 1990s had significant labor consequences. Workers who lost field jobs filed a class action, and the company paid more than $5 million in 1998 according to the cited material. A separate dispute emerged in 2008, when employees sued Chief Executive Officer Robert Buker, Chairman William S. White, members of White's family, and the Charles Stewart Mott Foundation. The employees alleged that the employee stock ownership plan had not received full value after outside parties were said to have made higher offers for the company. U.S. Sugar disputed the claim that those offers represented the company's fair market value. The company's landholdings also placed it at the center of Everglades policy. In June 2008, Florida announced negotiations to purchase approximately 187,000 acres and associated production assets for an estimated $1.7 billion under the Comprehensive Everglades Restoration Plan. A revised proposal later reduced the reported offer to $1.34 billion and allowed the Clewiston sugar mills to remain in operation. Critics argued that the revised structure would prolong sugarcane cultivation in the Everglades Agricultural Area. In October 2010, U.S. Sugar sold 26,800 acres to the South Florida Water Management District for the River of Grass restoration project. Today, U.S. Sugar remains a privately held agribusiness based in Clewiston. Its operations cover more than 230,000 acres across several South Florida counties and include sugarcane, refined sugar, citrus, sweet corn, and other agricultural activities. The company remains one of the largest employers in the Glades region and an important participant in the economics, labor debates, water-management disputes, and environmental policy of South Florida.
