Management statement

Optima Bank continued its growth trajectory in the third quarter of 2025, delivering a solid set of results that underscore the strength of our franchise, the effectiveness of our execution, and our ability to capitalize on favorable macroeconomic conditions and sustained demand for credit.

Commercial momentum remained strong, fully aligned with our 2025 guidance. Deposit growth accelerated in Q3, with total deposits increasing by €456mn on a quarterly basis — a 9% quarter-on-quarter rise and an impressive 37% year-on-year increase. They reached €5.6bn, reflecting the deep trust of our customers and our competitive positioning in the market.

Assets under management followed a similar trend, reaching €5.6bn — up 9% from the previous quarter and 29% year-on-year. Our loan book also expanded, growing 5% quarter-on-quarter and 34% year-on-year to €4.4bn.

We continued to deliver strong financial performance, with net interest income increasing sequentially, offsetting the impact of lower base rates through higher volumes. Fee income remained robust, growing 10% quarter-on-quarter. Our net interest margin for the first nine months stood at 3.34%, while our net fee margin reached 0.87% — both well ahead of domestic peers.

We maintained a disciplined approach to cost management, while our cost of risk declined compared to Q2, further supporting bottom-line performance. Despite the declining rate environment, we grew our nine-month net profit by 14% to €123.4mn, and we remain confident in achieving our full-year 2025 net profit target of over €160mn.

We continue to deploy capital selectively, with a clear focus on retaining high returns. This quarter, we delivered a Return on Tangible Equity of 25.3%, showcasing once more the structural strength of our franchise on delivering high double-digit returns.

The macroeconomic backdrop remains supportive, with continued GDP growth, subdued inflation, and declining unemployment. We continue to invest on digital transformation, risk management, and customer experience to ensure long-term competitiveness and growth.

Finally, it is always an honour to receive an award and recently, Optima bank was named "Best commercial bank – Greece 2025" by International Banker. This is a recognition of the efforts of all our people here at Optima, the consistent growth and the health of the business. We remain committed on sustaining this momentum, enhancing profitability, and delivering strong returns for our shareholders.
