In this article, we will list the 5 Best Industrial Automation Stocks to Buy Now. Please visit 10 Best Industrial Automation Stocks to Buy Now if you’d like to see an extended list and the methodology behind it.
5. Lincoln Electric Holdings, Inc. (NASDAQ:LECO)
Lincoln Electric Holdings, Inc. (NASDAQ:LECO) is one of the Best Industrial Automation Stocks to Buy Now. On June 30, Lincoln Electric Automation began its Demo Days 2026 event in Scheifling, Austria, highlighting automated welding, cutting and inspection systems. The product lineup included Linc-Cut, ENSPECTOR automated quality inspection, PythonX structural automation, SBA 400 beam welding with a handling robot, SBA Conti+ high-volume welding automation, the Cooper cobot and proFIT software.
Welding remains one of the clearest areas where industrial companies can use robotics to address labor constraints, quality consistency and throughput. Lincoln Electric is not a pure-play robot maker, and welding consumables still matter to the broader business. But its automation segment gives it a practical role in shop-floor modernization, especially where metal fabrication customers want complete systems rather than standalone machines. The company’s relevance comes from making automation usable in difficult production environments.
Lincoln Electric Holdings, Inc. (NASDAQ:LECO) makes welding, cutting and automation systems used in fabrication, heavy industry and manufacturing.
4. ATS Corporation (NYSE:ATS)
ATS Corporation (NYSE:ATS) is one of the Best Industrial Automation Stocks to Buy Now. On May 28, ATS reported fiscal fourth-quarter results that kept the automation story grounded in actual systems revenue rather than concept-stage technology. Fiscal 2026 revenue rose 17.4% to C$2.973 billion, while adjusted revenue rose 10.8% to C$2.970 billion and adjusted EBITDA increased to C$413.0 million. The company also reported C$744.3 million in adjusted revenue for the fourth quarter.
ATS is a cleaner fit for this topic because it builds automation systems and equipment for customers that need custom production, assembly and testing solutions. Its mix also includes services and spare parts, which can support customer relationships after initial installations. The stock is still exposed to project timing and customer spending cycles, so growth is unlikely to be perfectly smooth. But ATS remains one of the more direct US-traded ways to track demand for industrial automation integration.
ATS Corporation (NYSE:ATS) designs and builds automated manufacturing systems, equipment and services for industrial and regulated markets.
3. Emerson Electric Co. (NYSE:EMR)
Emerson Electric Co. (NYSE:EMR) is one of the Best Industrial Automation Stocks to Buy Now. On June 15, Emerson added combustible gas detection to its core wireless sensor portfolio with the Rosemount 928 wireless gas monitor. The sensor supports percent lower explosive limit monitoring over WirelessHART networks, giving industrial operators another way to detect combustible gas risks without relying only on hardwired infrastructure. This is a relevant automation development because modern process plants increasingly depend on connected sensors, safety data and control systems to run with fewer blind spots.
Emerson is not a narrow factory robotics name, but it is one of the central companies in process automation, measurement, instrumentation and industrial software. The new sensor also fits the broader push toward industrial internet-of-things deployments, where safety and operational data become part of the control environment. Cyclical process markets still matter, but Emerson’s automation focus remains clear, especially in plants where reliability and safety drive spending.
Emerson Electric Co. (NYSE:EMR) provides automation technology, measurement instruments, control systems and industrial software for process and hybrid industries.
2. AMETEK, Inc. (NYSE:AME)
AMETEK, Inc. (NYSE:AME) is one of the Best Industrial Automation Stocks to Buy Now. On June 30, Barron’s discussed Mizuho’s physical AI framework and included AMETEK among preferred companies tied to the automation and component layers of the trend. The fit is less about robots as a headline category and more about the instrumentation, precision motion, sensing and electromechanical systems that make automated equipment useful. AMETEK is not a pure-play automation company, so it needs the edge-case label.
Still, the company describes itself as a supplier of automation and precision motion control solutions, and those capabilities matter in manufacturing, testing, inspection, aerospace, medical and process environments. The stock also brings a steadier industrial technology profile than smaller automation specialists, though that comes with less thematic purity. For this list, AMETEK earns its place because industrial automation depends on accurate measurement and motion control as much as it depends on visible robotics.
AMETEK, Inc. (NYSE:AME) manufactures electronic instruments and electromechanical devices, including precision motion, sensing and automation-related technologies.
1. Parker-Hannifin Corporation (NYSE:PH)
Parker-Hannifin Corporation (NYSE:PH) is one of the Best Industrial Automation Stocks to Buy Now. On June 30, Barron’s discussed Mizuho’s physical AI investment framework and included Parker-Hannifin among companies positioned in the component layer that supports automation. The angle is straightforward: robots, automated lines and smart machines still need motion, control, fluid handling and electromechanical systems to function reliably in the physical world.
Parker-Hannifin is not a pure-play automation stock, and aerospace, mobile hydraulics and other industrial end markets remain important to the company. However, its motion and control technologies are foundational enough that excluding it would make the industry map less honest. Industrial automation is not only software, sensors and AI. It is also the high-spec components that translate instructions into movement, pressure, force and positioning. Parker-Hannifin’s role sits in that less flashy but vital layer of the automation stack, where uptime and precision matter more than marketing vocabulary.
Parker-Hannifin Corporation (NYSE:PH) provides motion and control technologies across industrial, mobile, aerospace and automation-related markets.
While we acknowledge the potential of PH to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.
