What Global Investment Holdings does

Global Investment Holdings (GIH; legal name Global Yatırım Holding Anonim Şirketi) is a publicly listed Turkish diversified investment holding company headquartered in Şişli, Istanbul, founded in 1990 as a brokerage firm and operating as a holding structure since 2005. The company is listed on Borsa İstanbul under ticker GLYHO (listed since 2004) and manages six business lines through majority- or wholly-owned subsidiaries: Port Infrastructure via Global Ports Holding (the world's largest independent cruise port operator, 35 ports across 20 countries, 20M+ passengers annually); Finance via İstanbul Asset Management (Turkey's largest independent asset manager), Global Securities, and Global MD Asset Management; Gas via Naturelgaz (Turkey's leading non-piped CNG/LNG distributor); Power Generation via Consus Enerji (biomass, solar, co/trigeneration); Mining via Straton Mining (feldspar, in a country holding ~15% of global reserves); and Real Estate via Ardus Real Estate Investments (Van Shopping Center, Rıhtım51/Karaköy). GIH operates across 4 continents and 20+ countries with 501–1,000 employees.

The company makes money through a mix of transaction-based and recurring revenue mechanics: port concession fees and passenger-related charges at cruise ports; management fees and brokerage commissions in financial services; CNG/LNG bulk sales in gas distribution; power sales and energy services in generation; mineral sales in mining; and rental/lease income in real estate. Customer segments span major cruise lines and shipping companies (enterprise B2B), domestic and international retail and institutional investors (B2C/B2B financial services), and industrial/commercial gas and energy buyers. GIH's go-to-market is sales-led and direct, supplemented by a structured investor relations program (quarterly financial presentations, annual reports, teleconferences) and a digital presence across LinkedIn, Facebook, Instagram, and X. The company's stated technology posture is anchored in an ISO/IEC 27001-certified Information Security Management System and KVKK (Turkish GDPR-equivalent) compliance, rather than in proprietary software or platform IP. The conglomerate pursues first-mover positions in nascent or high-growth sectors and reports a corporate governance rating of 9.41/10 (Kobirate, Nov 2025) and credit ratings of A- (tr) national / BB international (JCR Eurasia, Dec 2025).
