What Kalyon Holding does

Kalyon Holding is a privately held Turkish conglomerate headquartered in Üsküdar, Istanbul, with origins dating to 1944 and formal establishment as Kalyon İnşaat in 1974 by the Kalyoncu family. The group operates across four core business areas: construction (highways, airports, railways, pipelines, metro/metrobus, water systems), investment and concessions (build-operate-transfer highway and airport operations including Kuzey Marmara Otoyolu and Istanbul Airport), energy (a 5.6 GW renewable portfolio spanning solar, wind, and hydroelectric generation), and industry (the Kalyon PV vertically integrated solar panel factory producing ingot-to-module at 2 GW capacity).

The group generates revenue through multiple streams: one-time construction contracts (large-scale infrastructure bids), managed-services concession toll revenue, hardware sales of domestically manufactured solar modules (over 90% local content), recurring energy generation offtake, and one-time real estate sales under the Nevbahar brand. Go-to-market is enterprise field sales targeting Turkish government ministries, state-owned enterprises such as BOTAŞ, and international public-sector clients in Qatar, Albania, Saudi Arabia, Iraq, Syria, and Cyprus, supplemented by direct enterprise sales of solar modules to energy companies.

With approximately 35,000 employees, the group has built proprietary assets including the world's first fully integrated solar PV factory under one roof, Turkey's first floating LNG storage and regasification terminal (ETKI Liman FSRU), and the Kalyon Karapınar Solar Power Plant (1,350 MWp, the largest in Turkey and Europe). The corporate structure encompasses wholly owned subsidiaries across construction, energy, real estate, venture capital (Kalyon VC, est. 2021), cultural initiatives (Kalyon Kültür), and education (Hasan Kalyoncu University).
