These Greek publicly traded companies are primarily large, well-established firms. The list is dominated by financial services, with Eurobank, Piraeus, National Bank of Greece, and Alpha Bank all being major players. Other significant sectors include utilities with PPC S.A., and construction with Aktor Group and GEK TERNA Group.
A notable pattern is the concentration of headquarters in Athens, indicating its role as the commercial and financial hub of Greece. While many companies like National Bank of Greece (founded 1841) have a long history, some, such as Aegean Airlines (founded 1999) and Sani/Ikos Group (founded 2015), represent more recent ventures.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
