Expansion highlights5 records

Broad incumbents

• Marsh (Greece): Global insurance brokerage and risk advisory firm with a Greek presence. Comparable because it competes for the same large enterprise risk-management mandates in specialty lines (credit, surety, cyber, D&O) that NAK targets, although at significantly greater scale and geographic reach.
• Lockton: Largest independent global insurance brokerage. Comparable as a specialty-focused broker competing for large and complex enterprise accounts across similar specialty lines (D&O, cyber, M&A, surety).
• Aon (Greece): Global insurance and reinsurance broker operating in Greece. Direct competitor for enterprise insurance placement across the same specialty and commercial lines as NAK, with deeper multinational servicing capability.
• Willis Towers Watson (WTW): Global advisory, broking, and solutions firm with insurance brokerage operations in Greece. Comparable as it serves large Greek corporates across specialty lines (including D&O, M&A, construction) where NAK also operates.
• Arthur J. Gallagher & Co. Global insurance brokerage and risk management services company. Comparable for competing in specialty insurance placements for mid-to-large enterprises, including credit, surety, and construction risks where NAK is active.
• Howden: International insurance broker group with growing Southern European presence. Comparable because it competes in specialty commercial lines and has been expanding its specialty platform across Europe in a similar manner to NAK's specialty focus.

Direct peers

• Atradius: Global trade credit insurance provider and NAK's primary credit insurance partner. Comparable because it both underwrites and distributes credit insurance that NAK brokers in Greece — making it both partner and adjacent competitor in the credit insurance value chain.
• Coface: Global trade credit insurance provider. Comparable because it competes directly in the same Greek credit insurance market where NAK holds 12%+ share, offering overlapping products to similar enterprise clients.
• Interamerican (Achmea Group): Greek insurer and insurance group that is both NAK's strategic partner (for Surety Bonds since 2017) and a competing distributor in Greek commercial insurance. Comparable as a hybrid carrier-broker operating in the same Greek specialty lines.
• Generali Greece: Greek subsidiary of Generali Group, NAK's aquaculture insurance partner since 2012. Comparable as both a carrier partner and competing distributor in Greek commercial and specialty insurance, including aquaculture, where NAK holds 50% share.
