What OYAK does

OYAK (Ordu Yardımlaşma Kurumu) is Turkey's largest supplementary occupational pension fund, established in 1961 under Law No. 205 to serve Turkish Armed Forces personnel (commissioned officers, non-commissioned officers, military civil servants, and specialized sergeants). The fund serves over 508,000 members through mandatory salary-deducted contributions and provides lifetime pension payments via the Emekli Maaşı Sistemi (EMS) after 10 years of membership, alongside housing loans, healthcare discounts, and a digital lifestyle platform. OYAK has evolved from a pure pension provider into a diversified industrial holding company managing USD $20 billion in assets.

The conglomerate operates 140+ portfolio companies across nine sectors and 24 countries with 38,000+ employees: mining & metallurgy (ERDEMİR and İSDEMİR, producing 8.1 million tons of crude steel annually; Turkey's largest integrated steel producers); automotive (the OYAK-Renault joint venture commanding 44.4% of Turkey's total automobile production in 2025, MAİS distribution with 12.4% market share, and the OYAK HORSE powertrain JV); energy (GüzelEnerji fuel distribution at 1,050+ stations, İSKEN power generation at 1,360 MWe, OYAKPV solar panel manufacturing, Otojet EV charging, OYEN renewables, Milangaz LPG); cement (OYAK Çimento at 24 million tons capacity, Turkey's largest domestic producer); chemicals & agriculture (Akdeniz Chemson as the world's largest PVC stabilizer producer, Almatis as global specialty alumina leader, Kümaş refractories, HEKTAŞ crop protection); logistics (OMSAN, OYAK Liman at 21.72M metric tons handled in 2025, Port Yarımca Ro-Ro terminal); food (Sagra, 90-year-old chocolate brand; TAMEK processed foods); and finance (OYAK Yatırım investment banking, OYAK ANKER Bank in Germany). Six subsidiaries are publicly listed on Borsa Istanbul (EREGL, ISDMR, OYAKC, HEKTS, OYYAT, OYAYO).

OYAK generates revenue through multiple streams: compulsory member contributions (subscription/recurring), investment returns and dividends from its industrial portfolio, and commercial sales of steel, cement, automotive vehicles, fuel, electricity, chemicals, and consumer goods across B2B enterprise channels and B2C networks. Distribution is delivered through owned dealership networks, regional cement facilities, the TotalEnergies-branded station network (770+ stations under license), MAİS automotive dealers, and global chemical distribution (100+ countries). The organization pursues a B2B enterprise sales-led go-to-market across industrial verticals, supplemented by direct institutional distribution to its captive military member base.
