• China Communication Construction Company (CCCC): State-linked infrastructure company involved in China's expressway and toll-road construction and operations; comparable as a major state-aligned entity delivering motorway build-and-operate programs at scale.
• Abertis: World's largest toll-road operator managing a global portfolio of motorways with free-flow electronic tolling; comparable in large-scale toll-road operations and infrastructure asset management.
