Gardner Denver

Gardner Denver was an American industrial machinery company whose origins extended back to 1859, when Robert Gardner established the Gardner Governor Company in Quincy, Illinois. The company initially became known for governors used to regulate the speed of steam engines. Its early success gave it a foundation in mechanical engineering and industrial equipment, and by the turn of the twentieth century it had sold more than 150,000 governors in the United States and Canada. The business developed beyond engine governors as industrial customers adopted compressed-air, pumping, drilling, and other machinery. In 1927, the Gardner Governor Company merged with Denver Rock Drill Company, creating Gardner-Denver. The combination linked Gardner's expertise in mechanical controls with Denver Rock Drill's drilling-equipment heritage and helped establish the company's later identity as a diversified industrial machinery supplier. During the twentieth century, Gardner Denver expanded through product development and corporate transactions. Its portfolio came to include air compressors, vacuum pumps, blowers, pumps, drilling equipment, and related equipment and services used in manufacturing, construction, mining, energy, transportation, and other industrial applications. The company was first listed on the New York Stock Exchange in 1943. Negotiations concerning possible combinations with Dresser Industries and Cooper-Bessemer in the late 1950s did not produce agreements, but Gardner Denver later became part of Cooper Industries in 1979. Cooper Industries reorganized its operations in 1994, spinning off the Gardner Denver Industrial Machinery Division as an independent public company. Gardner Denver subsequently operated as Gardner Denver Inc. and continued to build its business around engineered equipment for air compression, vacuum generation, fluid handling, drilling, and industrial process applications. Its customers generally purchased equipment as part of larger operating systems rather than as consumer products, making reliability, maintenance, energy use, and application-specific engineering central to the brand's market position. In 2013, private-equity firm Kohlberg Kravis Roberts & Co. acquired Gardner Denver for a reported $3.9 billion. The company returned to the public markets through an initial public offering in 2017, while KKR retained a substantial minority interest. The transaction also included an employee-equity initiative for approximately 6,000 permanent employees; the related deferred stock units were reported to have reached an approximate value of $100 million after the IPO. Gardner Denver ceased to exist as an independent corporate entity in 2020. Its business was combined with the industrial segment spun off from Ingersoll-Rand plc in a Reverse Morris Trust transaction. The resulting company adopted the Ingersoll Rand name, while the former Ingersoll-Rand HVAC operations became Trane Technologies. The transaction left Gardner Denver and Ingersoll Rand industrial-segment shareholders with approximately 49.9% and 50.1% of the new Ingersoll Rand, respectively. Gardner Denver's product technologies, brands, facilities, employees, and customer relationships therefore continued within Ingersoll Rand rather than under Gardner Denver as a standalone company.

Gardner Denver's corporate history began in 1859 with Robert Gardner's Gardner Governor Company in Quincy, Illinois. Gardner developed an effective flyball governor for controlling steam-engine speed. The company sold more than 150,000 governors in the United States and Canada by the beginning of the twentieth century, establishing an early reputation in industrial mechanical engineering. The company broadened its activities into machinery related to compressed air and other industrial applications. In 1927, Gardner Governor merged with Denver Rock Drill Company and became Gardner-Denver. The merger combined the governor business with a company associated with drilling and rock-excavation equipment. Over subsequent decades, Gardner Denver developed and acquired capabilities in compressors, pumps, vacuum equipment, blowers, and drilling machinery. Gardner Denver became a New York Stock Exchange company in 1943. Merger discussions with Dresser Industries and Cooper-Bessemer during the late 1950s did not result in completed combinations. In 1979, however, Gardner Denver was acquired by Cooper Industries. Cooper later spun off the Gardner Denver Industrial Machinery Division in 1994, creating an independent Gardner Denver company. As an independent public company, Gardner Denver served industrial, construction, mining, energy, transportation, and manufacturing customers. Its equipment was typically sold into production systems and infrastructure projects, with recurring demand for maintenance, replacement parts, and technical support. The company consequently operated as an industrial technology and machinery supplier rather than a consumer-facing brand. KKR acquired Gardner Denver in 2013 for a reported $3.9 billion, taking the company private. Gardner Denver subsequently returned to the public markets through a 2017 IPO. KKR retained an approximately 35% interest, and the company also created a deferred-stock-unit program for permanent employees. The employee awards were described as part of KKR's employee-engagement strategy and were reported to have reached an approximate value of $100 million following the IPO. The independent Gardner Denver corporate era ended in 2020. The company combined with the industrial segment separated from Ingersoll-Rand plc in a Reverse Morris Trust transaction. The new company adopted the Ingersoll Rand name, while the former parent company's HVAC business became Trane Technologies. Shareholders of Gardner Denver and the separated Ingersoll Rand industrial business received approximately 49.9% and 50.1% of the combined company, respectively. Gardner Denver's operations and product heritage therefore continued inside Ingersoll Rand, but Gardner Denver was no longer a separate listed company or standalone corporate group.
