GE Company Introduction
General Electric Company (GE) is a renowned multinational conglomerate with diversified businesses spanning energy, aviation, healthcare, renewable energy, and digital industries. Below are its key details:
1. Company Overview
- Founded: 1892 (merger of Edison Electric Light Company and Thomson-Houston Electric Company)
- Headquarters: Boston, Massachusetts, USA
- Founders: Thomas Edison (technical pioneer), Charles Coffin (business integrator)
- Current CEO: Larry Culp (since 2018)
- Market Cap: ~$120 billion (2023 data, adjusted after spin-offs)
2. Core Business Segments
After strategic restructuring, GE now focuses on three main sectors:
- Aviation (GE Aerospace)
A global leader in aircraft engines and systems, including CFM International’s (joint venture with Safran) LEAP engines. - Healthcare (GE HealthCare)
Spun off in 2023, specializing in medical imaging, ultrasound, and life care equipment (e.g., CT, MRI machines). - Energy Transition (GE Vernova)
Launched in 2024, combining renewable energy (wind, hydro), gas power, and grid solutions.
3. Historical Milestones
- Early 1900s: Pioneered electrification, inventing the first commercial incandescent lamp and X-ray machine.
- 1970s: Entered aviation with the GE90 jet engine.
- Post-2008: Restructured after the financial crisis, divesting GE Capital.
- 2015-2020: Pushed digital transformation with the Predix industrial IoT platform.
- 2020s: Spun off non-core assets (e.g., appliances, biopharma) to focus on advanced manufacturing.
4. Presence in China
Since 1906, GE has contributed to projects like the Three Gorges Dam and COMAC C919, with multiple R&D and manufacturing sites (e.g., Beijing, Shanghai, Wuxi).
5. Recent Developments (2023-2024)
- Completed spin-offs of GE HealthCare and GE Vernova, leaving GE Aerospace as the remaining public entity.
- Accelerated sustainable tech R&D, including hydrogen-powered turbines and hybrid-electric aircraft engines.
