About Company :
Cubic Corporation: A Snapshot
Cubic Corporation is an American technology company specializing in public transportation systems and defense & mission solutions. Headquartered in San Diego, California, it has built a strong reputation over decades for innovation in both transit fare collection and defense, intelligence, training, and related services.
History & Origins
- Founded in 1951 by Walter J. Zable, Cubic began life with its first product—an electronic device for measuring microwave power (a calorimetric wattmeter).
- Over the ensuing decades, it expanded into many areas, including land and off-shore surveying (using products like Electrotape, Autotape, ARGO), electronic scoreboards, and microprocessor-controlled elevator systems.
- In the early 1970s, Cubic moved into mass transit systems, beginning with fare collection and ticketing, a field which remains central to its business today.
Business Units & Main Offerings
Cubic operates primarily through two major segments:
- Cubic Transportation Systems (CTS)
- Provides fare collection infrastructure: smart card readers, ticket machines, gates, back-end systems, operations & revenue processing.
- Works with public transit agencies globally; has deployed many automated fare collection (AFC) systems, mobile ticketing, contactless payments, etc.
- Cubic Mission and Performance Solutions (CMPS) (formerly defense segments)
- Offers capabilities in C4ISR (command, control, communications, computers, intelligence, surveillance, reconnaissance), and training systems.
- Also includes secure communications, support services, live/virtual training, and related mission-critical technology for governmental and allied customers.
Recent Developments & Positioning
- In 2021, Cubic was acquired by Veritas Capital and Elliott Management, transitioning from a public to a private company.
- As of 2025, Stevan Slijepcevic is the CEO, leading business across both transportation and mission solutions.
- They emphasize innovation: simplifying mobility (making public transit safer, more efficient, more convenient), while also helping defense and intelligence clients improve readiness, situational awareness, and performance.
Cubic Corporation remains a key player at the intersection of transportation technology and defense innovation, combining decades of legacy engineering with modern digital and infrastructure challenges.
