What AUMA does

AUMA is a privately held German manufacturer of electric valve actuators and gearboxes, founded in 1960 in Müllheim, Baden-Württemberg, and operating today as AUMA Riester GmbH & Co. KG with approximately 2,900 employees across 35 global locations. The company designs and builds modular electric actuators across three core hardware lines — multi-turn (SA series), part-turn (SQ series), and linear units — complemented by matched gearboxes, AUMA MATIC and AUMATIC control units, and multi-protocol communication interfaces (Profibus, Modbus, Foundation Fieldbus, Profinet, HART, WirelessHART). AUMA serves six critical-infrastructure end-markets: water, power, oil & gas, general industry, marine, and nuclear, with specialized certified services for SIL (IEC 61508), ATEX (EN 60079-17), and nuclear applications. The portfolio is extended through the PROFOX-X intelligent automation platform and the CORALINK digital ecosystem (AUMA Cloud, Assistant App, CDT), and through acquired brands DREHMO, SIPOS Aktorik, AUMA Drives, and AUMA Industry + Marine.

Revenue is generated primarily through project-based hardware sales of actuators, gearboxes, and controls to engineering firms, EPC contractors, and end-user operators, supplemented by professional services (field services, retrofit, Smart Lifetime Services) and an emerging recurring revenue stream from CORALINK subscription licenses and AUMA Academy training (priced €750-€2,050 per course). Go-to-market is direct enterprise field sales through a global footprint anchored by regional HQs in Taicang (China), Canonsburg PA (USA), and Bangalore (India). The company positions itself among the world's top three electric actuator manufacturers alongside Rotork, Flowserve, ABB, Emerson, and Honeywell, operating in a market forecast to reach US$9.54 billion by 2033 at a 6.67% CAGR. AUMA is family-owned with no external private equity or public listing, governed by a six-member managing director board led by Chairman Dr. Jörg Hoffmann.

• Honeywell: US-listed conglomerate whose Process Solutions division offers electric actuators as part of integrated control and safety systems, often bundled with Experion DCS in oil & gas and power projects.
• Siemens: German industrial conglomerate that spun off its electric actuator business in 1999 (which became SIPOS Aktorik, now owned by AUMA); continues to compete indirectly via larger automation systems that integrate actuator controls.
• ABB: Swiss-Swedish industrial automation and electrification major offering electric actuators as part of its process automation portfolio; competes with AUMA in power, water, and oil & gas applications.
• KSB: German pumps, valves, and related systems manufacturer with electric actuator offerings; competes with AUMA in water/wastewater, power, and industrial process applications, primarily in European markets.
• Schneider Electric: French industrial automation and energy management major; competes with AUMA in water/wastewater and power segments through its process automation offerings, often bundled with EcoStruxure platform.
• Spirax Group: UK-listed thermal energy and fluid technology specialist (Spirax Sarco, Gestra, Crosby); competes with AUMA in industrial process steam and power applications where electric actuators are integrated into broader thermal management systems.

Direct peers

• Rotork: UK-listed global market leader in electric actuators and flow control, with overlapping product portfolios (multi-turn, part-turn, linear actuators) and direct head-to-head competition across water, power, and oil & gas segments.
