The thegentlemen ransomware group listed Yapı Merkezi on its data leak site on 2026-09-07. Country: TR Sector: Manufacturing Domains named: ym.com.tr, rocketreach.co Claim as published on the leak site: ym.com.tr rocketreach.co/yapi-merkezi-profile_b5c7f2fff42e0db7 YM Group is a Turkish family-owned manufacturing and brand house founded in 1986 in Istanbul by Yüksel Mehmet Yıldırım, built on a flexible-packaging plant in Çorlu (Halal-certified, exporting to Europe/MENA). Its crown jewel: it owns and operates the legendary American trail-running brand Ultimate Direction (the 1935 inventor of the hydration pack) — designing, manufacturing in Turkey and distributing it worldwide — plus its own jewelry line Ela by YM and investment arm YM Capital. The group follows the classic ladder: manufacturing → own brands → capital, with Halal certification as a niche edge for Gulf/Asian markets. Small core team (~110), private, low-profile, no public financials. Bottom line: a quiet Turkish industrial family that turned commodity packaging profits into ownership of an iconic American outdoor brand.
