Key Stats
Emerson Electric Co. is an American multinational technology and engineering company headquartered in St. Louis, Missouri. It designs and manufactures automation software, process control systems, valves, measurement instruments, and related solutions for industrial, commercial, and consumer markets worldwide.
Founded in 1890 as a maker of electric motors and fans, Emerson spent much of the 20th century diversifying across industrial segments. Since 2021 the company has been shedding non-core businesses and reorienting itself around industrial automation and software, completing divestitures worth over $17 billion while acquiring National Instruments for $8.2 billion and building a majority stake in AspenTech.
Emerson is a Fortune 500 company and one of the longest-running dividend growers in U.S. history, with more than 40 consecutive years of dividend increases during the tenure of its longest-serving CEO, Charles F. Knight. Its fiscal year ends September 30.

Emerson Electric History
Emerson Electric Acquisitions
Emerson’s acquisition history breaks cleanly into three phases: a mid-century diversification drive that built the company into a multi-industry manufacturer, a strategic consolidation under Chuck Knight that created its process management identity, and a 2021–2025 portfolio reset that is still playing out.
The foundation was laid by W.R. Persons between 1954 and 1973, when he completed 36 acquisitions to move Emerson beyond fans and motors. InSinkErator, Ridge Tool, and Therm-O-Disc all joined the portfolio in this period, as did U.S. Electrical Motors. Persons’ approach — decentralized management, common financial discipline, shared cost reduction targets — became the template that Chuck Knight inherited and refined.
Knight’s additions were larger and more focused. Rosemount in 1976 gave Emerson a strong position in process measurement instruments used across oil and gas, chemical, and pharmaceutical plants. Copeland in 1986 made Emerson the world leader in compressor technology for refrigeration and air conditioning. Fisher Controls, acquired in 1992 for roughly $1.3 billion, added control valves and regulators that are now central to the process management business. David Farr continued this thread after 2000, picking up Avansys in China (2001), Marconi’s outside plant and power systems (2004), and Germany’s Knürr AG (2006) to deepen the network power segment.
The Karsanbhai era has been as notable for what Emerson sold as for what it bought. The InSinkErator sale to Whirlpool and the $14 billion Climate Technologies deal with Blackstone removed two large, hardware-centric businesses that no longer fit the automation focus. In their place came National Instruments ($8.2 billion, 2023), which extended Emerson’s reach into discrete manufacturing, semiconductors, and test-and-measurement software — segments with faster organic growth profiles than Emerson’s traditional process industries. The bid for full control of AspenTech, if completed, would make Emerson one of the largest pure-play industrial software and automation companies in the world.
Emerson Electric Revenue
Revenue declined significantly in FY2022 as Emerson reclassified Climate Technologies as a discontinued operation and completed the InSinkErator sale. The rebound in FY2023 and FY2024 reflects a full year of National Instruments contributing and continued organic growth in process automation. Pre-FY2022 figures include businesses that have since been divested.
Emerson Electric Market Cap
Emerson’s market cap roughly doubled between 2020 and 2021 as investors re-rated the company on expectations of a portfolio transformation. The cap compressed in 2022–2023 as the restructuring created short-term earnings volatility, then rebounded sharply in 2024–2025 as the new automation-focused business model delivered consistent earnings growth.
Emerson Electric Competitors
Emerson competes across two broad arenas. In process automation — control systems, measurement instruments, valves, and related software — its main rivals are Honeywell International, Siemens, ABB, Yokogawa Electric, and Schneider Electric. In industrial automation hardware and software more broadly, Rockwell Automation and Parker Hannifin are also significant competitors. In the industrial software segment, now anchored by AspenTech and NI, Emerson faces a different competitive set that includes software-centric players such as AVEVA, Aspen’s own historical peers, and General Electric’s industrial software businesses.

FAQs
When was Emerson Electric founded?
Emerson Electric was founded on September 24, 1890, in St. Louis, Missouri. It was established as The Emerson Electric Manufacturing Company, backed by financier John Wesley Emerson, with engineering provided by Scottish-born brothers Charles and Alexander Meston. The company made its first electric fans available in North America in 1892.
What does Emerson Electric do?
Emerson designs and sells automation technology and software for industrial customers across oil and gas, chemicals, life sciences, food and beverage, power generation, and discrete manufacturing. Its core products include process control systems (DeltaV), measurement and analytical instruments (Rosemount), control valves (Fisher), and industrial software through its AspenTech and NI holdings. After a multi-year restructuring, the company no longer operates in consumer appliances or climate technologies.
What is Emerson Electric’s annual revenue?
Emerson reported net sales of $17.49 billion for its fiscal year ending September 30, 2024, a 15% increase over FY2023. Fiscal 2025 revenue reached approximately $18.0 billion. The FY2022 figure of $13.8 billion was lower than adjacent years due to the reclassification of Climate Technologies as a discontinued operation and the sale of InSinkErator.
Who are Emerson Electric’s main competitors?
Honeywell International, Siemens, ABB, and Schneider Electric are the most direct rivals across process automation. Rockwell Automation competes in factory and discrete automation, while Yokogawa Electric overlaps significantly in process control for chemical and oil and gas markets.
What major acquisitions has Emerson made recently?
The most significant recent deal was the $8.2 billion acquisition of National Instruments (NI) in October 2023, which added automated test and measurement systems for semiconductor, aerospace, and defense customers. Emerson has also built its AspenTech position — first combining its own industrial software with AspenTech in 2022, then proposing to acquire the remaining shares it does not own for approximately $6.5 billion in 2024–2025.
