Broad incumbents

• Huawei: Global telecom equipment vendor with end-to-end 5G, base station, and network infrastructure solutions. Comparable as a major competitor to Mikrolink in 5G smart pole, base station deployment, and telecom infrastructure projects across MENA and Central Asia.
• Ericsson: Global telecom infrastructure provider for 4G/5G networks. Açık Holding already partners with Ericsson Systems for 4G/5G projects in Qatar and UAE, making it a direct competitor and partner in the same telecom network deployment category.
• Schneider Electric: Global specialist in energy management and data center infrastructure including cooling, PDUs, and monitoring. Comparable to Boreas and Exagate offerings, and a likely competitor in data center projects where Serban also operates.
• ENKA İnşaat: Major Turkish engineering and construction firm with power generation, real estate, and retail operations. Comparable for the Serban data center construction and engineering EPC+ activities, with a similar international project delivery model.
• Koç Holding: Largest diversified Turkish industrial conglomerate spanning automotive, consumer durables, energy, and finance. Comparable as a Turkish holding with a similar conglomerate structure and global ambitions, though much larger and more diversified than Açık Holding.
• Sabancı Holding: Diversified Turkish conglomerate with operations in industry, financial services, and energy. Directly comparable as a multi-vertical Turkish holding company operating across B2B industrial and consumer segments with global footprint.
• Tekfen Holding: Turkish conglomerate active in construction, agriculture, and real estate with significant international operations. Comparable for diversified industrial holding structure and overseas project execution capabilities.
• Aselsan: Turkey's largest defense electronics company with a broad portfolio across military electronics, radar, and communications. Comparable as a leading Turkish defense firm operating within the same domestic defense ecosystem and government customer base.

Direct peers

• Vertiv: Specialized data center critical infrastructure provider (cooling, power, monitoring). Directly comparable to Boreas (HVAC/cooling) and Exagate (smart PDU/monitoring) product lines for data center operators globally.

Regional players

• Roketsan: Turkish defense industry company producing rockets, missiles, and advanced defense systems. Comparable as a Turkish defense player benefiting from the same localization trend driving CES's ballistic and composite materials business.
