Piraeus (ATHEX: TPEIR) and Accenture (NYSE:ACN) announced a significant expansion of their long-standing collaboration with the launch of a dedicated AI Hub – supported by Anthropic – designed to accelerate Piraeus' enterprise-wide AI transformation and set a benchmark for AI-driven banking in Greece.

The AI Hub will act as a central engine for designing, developing and scaling advanced AI capabilities across Piraeus' full value chain. By bringing together Accenture's industry and AI expertise, including its Data & AI Center of Excellence in Athens, with Piraeus' strategic AI roadmap, the Hub will drive the reinvention of banking processes across operations, customer experience, risk, and compliance, and modernize the technology backbone.

In parallel, the Hub will strengthen Piraeus' long-term AI capabilities by attracting, developing and upskilling specialized talent through targeted recruitment and structured learning programs, including Udacity, Accenture's AI-native learning and training platform. This approach supports the Bank's ambition to embed AI skills and ways of working deeply across the organization.

A key focus of the collaboration will be the development of secure, responsible and human-centric AI solutions, designed to autonomously support decision making, streamline complex processes and enhance both customer and employee experiences. Piraeus and Accenture, with its newly-formed Anthropic Business Group, will leverage the power of Anthropic AI models and platforms and its deep grounding in ethical AI principles to drive innovation in a responsible manner, ensuring that advanced AI solutions are aligned with the bank's values and regulatory requirements. This approach will support the development of secure, trustworthy, and scalable AI applications, to elevate human performance and the quality of banking services.

"The AI Hub represents a strategic inflection point for Piraeus," said Harry Margaritis, Group Chief Operating Officer, Piraeus. "We are advancing from individual AI deployments to a unified, enterprise-level capability that is deeply embedded in how the Bank operates. Our collaboration with Accenture, together with the integration of Anthropic's AI technology, enables us to scale advanced AI responsibly, anchored in strong governance, transparency and human control. This initiative empowers our people, reinforces trust with our customers and regulators, and builds a resilient, future-ready foundation for banking in Greece."

"This collaboration reflects the deep and longstanding relationship between Piraeus and Accenture, built on trust, value creation and shared ambition," stated George Pallioudis, Financial Services Lead at Accenture. "It's a testament to Piraeus' leadership commitment to AI adoption and a recognition of Accenture's leading role in AI-powered reinvention at scale."

Thomas Remy, Head of Southern Europe, Middle East & Africa for Anthropic, commented: "AI is transforming how banks operate, and it's vital that modern AI systems meet strong governance and regulatory requirements. Claude is built with the safety, reliability and transparency that highly regulated industries like banking demand. In partnering with Anthropic to power a new AI hub for Greek banking, Piraeus and Accenture have underscored our shared commitment to safe, responsible AI deployment."

The AI Hub builds on Piraeus' successful collaboration with Accenture to adopt a cloud first operating model, which has already accelerated digital service delivery, enhanced security and compliance, improved operational efficiency and supported the Bank's broader sustainability and modernization objectives.
