Broad incumbents

• Bilfinger: German industrial services provider with engineering, maintenance and consulting across process industries (chemicals, refining, power). Overlaps with HGH on plant engineering and EI&C but operates a much broader portfolio at significantly larger scale.
• KBR: Global engineering, procurement and construction firm with deep refining, petrochemical and chemical expertise. Directly overlaps HGH's process engineering and revamp services at far larger scale; competes for refinery turnaround scopes.
• Worley: Australian-headquartered global engineering services firm serving energy, chemicals and resources. Comparable in target customers (refining, petrochemical, chemical) but at significantly larger scale with global execution capability.
• Wood Group (Wood plc): UK-based global engineering and consulting firm focused on energy and the built environment. Directly comparable end markets (refining, chemicals, power) with engineering services overlapping HGH's process and EI&C scope.
• TÜV SÜD: German testing, certification and engineering services firm serving process industries. Comparable in regulatory and qualification expertise (ATEX, IEC, ASME) that HGH cites as a moat, but with much broader scope including testing and certification.
• Technip Energies: Global EPC leader for chemical, petrochemical and refining projects. HGH has executed engineering scope for Technip on Kazakhstan and Vietnam projects; Technip competes for the same full-scope work that HGH also targets.
• Fluor Corporation: US-based global EPC contractor with strong refining, petrochemical and chemical plant expertise. Comparable end markets and capability set, but operates at much larger scale with integrated construction execution.
• Jacobs Solutions: US-based global professional services firm with critical-infrastructure engineering for chemicals, advanced facilities and life sciences. Comparable across pharmaceutical plant engineering, but operates globally at significantly larger scale.

Direct peers

• ThyssenKrupp Uhde: German EPC contractor for chemical, petrochemical and fertilizer plants. Directly comparable as HGH has subcontracted engineering scope to Uhde on electrolysis and other projects, but operates at much larger scale.
• ILF Consulting Engineers: Austrian-German engineering consultancy specializing in industrial plant, energy and oil & gas engineering. Closest comparable peer in terms of consulting-style engineering services for process plant owners across multiple geographies.
