Caterpillar Inc (CAT  ) is a large scale American manufacturer of construction and mining equipment, engines, industrial gas turbines and diesel-electric locomotives. With the majority of its operations focused on designing, developing, engineering, manufacturing and marketing of machinery, engines and financial products to an international base of customers, Caterpillar currently sits at the top of its industry with over $89 billion USD in assets.

Tracing its origins to a 1925 merger between Holt Manufacturing Company and the C.L Best Company, Caterpillar Inc built the majority of its operations on manufacturing tractors that played an important support role in World War I. Responsible for shipping 1,200 tractors to England, France and Russia, Caterpillar's tractors, despite being designed for agricultural purposes, were sent directly to the battlefront for the purpose of hauling artillery and supplies. After the war, the company pivoted towards road construction equipment during the 1920s after the Federal Aid Highway Act of 1921 funded a US$1 billion federal highway building program. Caterpillar ultimately reorganized into its current form in 1986 when it moved its corporations to Delaware.

On the back of the post war construction boom, Caterpillar grew at a rapid rate, developing into a multinational corporation with noteworthy expansions into developing markets including its $125 million USD Caterpillar Suzhou facility in the People's Republic of China. With factories located in Russia, Germany, India, and China, much of Caterpillar's growth has been through acquisitions domestically and internationally including the recent acquisition of Electro-Motive Diesel for $820 Million USD in 2010. Recent major developments within the company including this acquisition suggest the corporation hope a rebounding US economy accompanies an increased demand for rail cars and manufacturing equipment. Furthermore, they are positioned to capitalize on growth in emerging markets such as India and China with significant investments in manufacturing within the two countries.
