What Ozaltın Holding does

Ozaltın Holding is a privately-held Turkish industrial conglomerate headquartered in Ankara, founded in 1965 by Nuri Özaltın. The group operates across five sectors — construction and contracting, infrastructure investment, mining, tourism and hospitality, and greenhouse agriculture — and employs between 5,001 and 10,000 people.

The construction arm is the historical core and remains the primary revenue driver, executing large-scale public infrastructure projects including motorways, bridges (notably the Osmangazi Bridge), tunnels (Belkahve), railways (Palu-Genç-Muş), and dams and hydroelectric power plants (Kiğı, Upper Beyhan, Upper Kaleköy). Subsidiary Kalehan Energy houses hydroelectric generation and the newly commissioned 60 MW Elmalı Solar Power Plant, signaling diversification into renewables. The group also holds the Gloria Hotels & Resorts brand in luxury hospitality and operates mining and greenhouse-agriculture assets.

The business model blends project-based public-sector contracting with BOT/concession-based infrastructure investment and operational cash flows from energy generation, hospitality occupancy, mining output, and agricultural produce. Government and public-sector entities are the primary customer segment, supplemented by international clients in Romania and the Middle East (Wadi Arab Water System II). Pricing and revenue mechanics reflect large-lump-sum EPC contracts, long-dated concession tariffs, and per-unit-of-sale income from hospitality, mining, and agriculture.

Ozaltın Holding is a Turkish conglomerate that fundamentally executes large-scale infrastructure construction contracts (motorways, bridges, tunnels, railways, dams, hydroelectric power plants) and invests in such projects via BOT concessions. Beyond construction, the group commercially owns and operates the Gloria Hotels & Resorts hospitality brand (including Gloria Serenity Resort, Gloria Golf Club, and Gloria Sports Arena), engages in mining & metals extraction, runs renewable-energy generation assets (60 MW Elmalı SPP and Kalehan Energy hydroelectric plants), and produces greenhouse agricultural goods.

The holding operates through distinct sector divisions and subsidiary brands including Gloria Hotels & Resorts (hospitality), various energy projects (solar, hydro), and infrastructure projects (motorways, bridges, tunnels, railways).
