Mitsubishi Electric Corporation

Factory AutomationAir ConditioningElevators

Mitsubishi Electric was carved out of one of Japan's oldest corporate empires in 1921, when the Mitsubishi shipyard's electrical equipment division was spun off as an independent company. The Mitsubishi name — three diamonds, chosen by founder Yataro Iwasaki in 1870 — carried enormous weight, and the new company used it to build everything from heavy electrical machinery to the world's best-selling air conditioners. The company's business spans five pillars: energy & industrial systems (generators, transformers, and factory automation), building systems (its air conditioners — the global market leader in split-type ACs under brands like Mr. Slim — and elevators), mobility (car electronics, train systems, and the automotive alternators and starters that go into millions of vehicles), and semiconductor & devices (power modules for EVs and industrial drives). Its factory automation division competes head-to-head with Fanuc and Siemens in robot controllers. Headquartered in Tokyo with about 150,000 employees and annual revenue near ¥5 trillion (US$33 billion), Mitsubishi Electric is a pillar of Japan's keiretsu system, sourcing and selling within the Mitsubishi network while competing globally. Its sustainability push — 'Environmental Vision 2050' — targets carbon neutrality through energy-efficient air conditioning and grid technologies. For builders and manufacturers, Mitsubishi Electric is the brand that cools, moves, and powers modern buildings and factories.

Siemens AG

AutomationElectrificationDigital Industries

Siemens began in 1847 when inventor Werner von Siemens — then an army officer — built an improved pointer telegraph and founded a company with Johann Georg Halske in a Berlin backyard. Within two decades the company was laying telegraph lines from London to Calcutta, and by the early 20th century Siemens was one of the world's first global technology companies — a record of invention that spans the dynamo, the electric locomotive, and the first commercial computer in Germany. Today Siemens is a sprawling technology group with four main businesses: digital industries (factory automation, industrial software like the Simatic PLC and the Xcelerator platform), smart infrastructure (building automation, electrical distribution, charging infrastructure), mobility (trains, rail automation, signaling — its Velaro high-speed trains run in China, Spain, and Turkey), and Siemens Healthineers (medical imaging and diagnostics). Its industrial software and automation form the backbone of Germany's Industry 4.0 push. With about 320,000 employees and annual revenue near €78 billion, Siemens has spent the past decade reshaping itself — selling its energy business (now Siemens Energy), its lighting business, and its gas turbines, while buying industrial software makers like Mentor and Altair. The result is a company that still builds trains and factories, but increasingly sells the software and data platforms that run them — the 175-year-old inventor remade as a digital industrial giant.
