What Solero Technologies does

Solero Technologies is a B2B automotive supplier of advanced controls, solenoids, valves, and actuators serving global vehicle OEMs, Tier 1 suppliers, and system designers across passenger cars, commercial vehicles, and off-highway/special vehicle markets. The company manufactures transmission solenoids, engine solenoids, stop-start accumulators, hydraulic control modules, active suspension components, thermal management valves, ADAS sensor cleaning valves, and mobile hydraulics systems, with the LINNIG sub-brand covering A/C compressor clutches, auxiliary drive clutches, belt drive systems, engine cooling systems, and shutting-speed regulators. Headquartered in Rochester Hills, Michigan, Solero operates seven manufacturing facilities in the United States (Water Valley, MS; Shelby, NC), Germany (Villingen, Markdorf, Malente), the Czech Republic (Prostějov), and Romania (Sibiu), with the Water Valley facility delivering nearly half of global output and Malente producing approximately 5 million units annually.

Solero's technology stack centers on electromagnetic valve engineering, proportional pilot control, linear sensing, active and semi-active damping actuation, and overmolded electronic assemblies, with a stated strong patent and IP portfolio across product categories. The business model is hardware sales to enterprise automotive customers through direct OEM field sales supplemented by an international LINNIG aftermarket distribution partner network spanning 20+ countries; pricing is quote-based B2B with no public disclosure. Solero was formed in February 2022 when Atar Capital completed the December 2021 carve-out acquisition of BorgWarner's North American Controls business and rebranded it under the Solero identity.

In April 2024, Solero announced the acquisition of Kendrion's automotive business, adding five European plants and one U.S. plant and expected to roughly double annual revenue, with product additions in intelligent actuators for EVs and sustainable mobility. The company has also executed defensive restructuring including a December 2025 announcement to close its Shelby, North Carolina plant with 102 layoffs amid auto-parts sector pressures. Solero is privately held by Atar Capital and operates with 1,001-5,000 employees globally.

Broad incumbents

• Aptiv: Aptiv focuses on vehicle electrical architecture, electronic control units, and advanced safety/ADAS components, serving the same OEM customer base with overlapping signal/power management and sensor-cleaning technology adjacencies.
• Denso: Denso manufactures a wide range of automotive electrical and electronic components, sensors, and thermal-management valves that overlap with Solero's solenoid, sensor, and thermal-management valve offerings across passenger and commercial vehicles.
• Continental AG: Continental's Hydraulic Brake Systems and vehicle electronics businesses overlap directly with Solero's solenoid and hydraulic control module portfolio; the Solero CEO previously led Continental's North American Hydraulic Brake Systems business.
• BorgWarner: Solero was carved out of BorgWarner's North American Controls business in 2021; BorgWarner remains a direct competitor in transmission solenoids, hydraulic control modules, and engine solenoids while operating a much broader powertrain and ePropulsion portfolio.
• Schaeffler: Schaeffler's Automotive Technologies division supplies engine, transmission, and chassis components—including variable valve timing systems and mechatronic modules—that compete with Solero's engine and drivetrain solenoid portfolio.
• ZF Friedrichshafen: ZF supplies transmission, driveline, and chassis systems to global OEMs and competes head-to-head with Solero in transmission solenoids, hydraulic control modules, and active/semi-active damping components.
• Robert Bosch: Bosch Mobility is a major Tier 1 with overlapping product lines in automotive electronics, transmission controls, hydraulic components, and ADAS sensor-cleaning technologies, supplying the same global OEM customers as Solero.

Direct peers

• Parker Hannifin: Parker's Motion Systems group produces hydraulic valves, proportional solenoid valves, and motion-control components with comparable specifications to Solero's mobile-hydraulics and active-suspension products, targeting similar industrial and off-highway OEMs.
• Moog Inc. Moog specializes in high-precision motion control, proportional valves, and actuators across industrial, aerospace, and automotive applications—closely analogous to Solero's solenoid/actuator core technology and domain-specialization positioning.
• Eaton: Eaton's Vehicle Group and hydraulics businesses manufacture mobile hydraulic valves and proportional control systems that overlap directly with Solero's NG04/06/10 proportional actuation mobile-hydraulics product family for off-highway and special vehicle markets.
