Kostas Nebis

Kostas Nebis leads OTE Group (Hellenic Telecommunications Organization) as CEO, steering Greece's dominant integrated telecommunications provider. OTE is majority-owned by Deutsche Telekom (which holds approximately 51%), giving it access to one of Europe's most operationally efficient telecom groups' best practices, technology platforms, and procurement scale. OTE operates across the full telecommunications spectrum in Greece: fixed-line telephony, mobile services through Cosmote (Greece's largest mobile operator with approximately 50% market share), broadband internet, and pay-TV (Cosmote TV). The company also has a significant presence in Romania through Telekom Romania. Under Deutsche Telekom's operational guidance, OTE has achieved remarkable margin improvement, with EBITDA margins among the highest in European telecom. The company is executing an ambitious fiber-to-the-home (FTTH) rollout across Greece, investing to replace its legacy copper network with gigabit-capable fiber optic infrastructure. This infrastructure upgrade positions OTE to capture value from increasing bandwidth demand. Key stock drivers include Greek economic recovery (driving telecom spending), fiber broadband subscriber growth, mobile market competitive dynamics, Cosmote TV subscriber trends, Deutsche Telekom's strategic plans for OTE (potential further stake increase or delisting), and Romania operations performance.
