"The Greek economy entered 202c supported by strong carry effects and solid fundamentals, remaining firmly on track for another year of solid growth outperformance relative to the euro area. In the face of renewed geopolitical uncertainty, Greece benefits from enhanced adaptability, supported by solid fiscal buffers and strengthened financial positions across the private sector. Key positive catalysts include peak Recovery and Resilience Facility (RRF) deployment, supportive financing conditions and a strong pipeline of investment projects. At the same time, structural improvements in the energy sector as well as export and tourism diversification further reinforce resilience against emerging risks, allowing Greece to remain in the expansionary phase of the investment cycle.

Within this backdrop, our solid performance in the first three months of 202c underscores the strength of the Greek economy and our Balance Sheet, setting the stage towards achieving our FY2c guidance. Our 1Ǫ2c PAT

amounted to €0.34b1, translating into an earnings per share of €1.431,2, with the return on tangible equity (RoTE) at 15.3%1,2, or 20.0% adjusting for excess capital. This performance reflects accelerating NII recovery, leveraging our recent healthy credit expansion, complemented by continued strength in fee and non-interest income generation.

Our capital position remains a key comparative advantage, balancing superior shareholder returns with strong capital buffers in an uncertain geopolitical environment, providing resilience as well as significant strategic optionality. With our capital build-up phase now behind us, we are shifting our focus towards the active deployment of our excess capital. Consistent with this strategy, our CET1 settled at 17.4%3 in 1Ǫ2c, incorporating class leading distributions to our shareholders totaling €1b4 through cash and buybacks, reaffirming our commitment to gradually utilize our capital buffers.

At the same time, we have taken a significant step in enhancing our fee-generating capabilities, singing an MoU that sets out our intention to enter into a long-term strategic partnership with leading global insurer Allianz. This has been complemented by the signing of an MoU that sets our intention to acquire a 30% minority stake in Allianz European Reliance, subject to regulatory approvals. This strategic partnership is expected to drive a meaningful uplift in our insurance income (c4x), supported by access to a comprehensive, market-leading product suite, whilst leveraging Allianz's expertise in products and sales as well as advanced digital capabilities, facilitating the transition and new

product offerings. From a financial perspective, the partnership is set to add more than 50bps in our RoTE, delivering an EPS accretion of +4%. Moreover, it strengthens our ability to deliver enhanced, customer-centric insurance solutions while maintaining a capital-light model, contributing to sustainable earnings growth and long-term value creation for our shareholders.

In an environment defined by heightened geopolitical uncertainty, our strategic priority remains unequivocal: to strengthen our role as a trustworthy financial partner to the Greek economy while continuing to evolve as a forward-looking, technologically advanced institution. As we complete the migration to our new Core Banking System, we are positioned well ahead of our European peers, enabling fast product innovation and greater operational resilience. At the same time, our sustained investment in our people and digital transformation enhances execution across all levels of the organization, ensuring that we deliver high end services to our clients. These efforts strengthen our capacity to expand lending in a disciplined manner, support households and businesses more effectively and navigate geopolitical volatility with confidence, creating value for our customers and shareholders."

Profitability

Group PAT1 amounted to €344m in 1Q26, up by +23% qoq, reflecting sustained NII recovery and continued strength in our fee and non-interest income.

NII continued on a recovery trend, increasing by 2% qoq to €541m in 1Q26, on the back of recent healthy asset growth, while NIM has broadly stabilized as spread compression has waned. These trends will continue, while base rate upward tendency, if maintained, will provide further support. Sustained balance sheet expansion supports a favorable NII trajectory in the coming quarters, reinforcing our confidence in delivering our FY26 guidance.

Fee and commission income increased by +8% yoy to €114m in 1Q26, driven by the retail segment (+20% yoy), spearheaded by the strong momentum in investment products, up by nearly +60% yoy, underscoring the effectiveness of our cross-selling strategy and increasing customer engagement. As a result, we have delivered impressive mutual fund market share gains of +0.7ppts ytd and +7.0ppts since YE23, reflecting the strength of our product offering and growing client confidence in our wealth management capabilities. On a quarterly basis, the decline reflects negative base effect due to high 4Q25 seasonal loan origination.

Operating expenses increased by +8% yoy to €246m in 1Q26, largely on the back of personnel expenses, reflecting increased remuneration mainly driven by collective agreements as well as our investment in human capital through variable pay and the onboarding of new talent and skills through hires, leveraging on VES offerings. Higher GCAs were driven by spending that enhanced customer experience, while depreciation charges derive from our sector-leading investments in technology and digital infrastructure exceeding €1b since 2020. These investments, notably the replacement of our Core Banking System, are translating into tangible gains in our productivity, commercial effectiveness, digital offering and cyber risk security. Alongside these strategic investments, our cost discipline remains intact, with 1Q26 C:I settling at 35.7%2 (34.3% reported), comfortably within our FY26 guidance.

Loan impairments stood at €39m in 1Q26, with the provisioning rate normalizing to 39bps from 46bps in 1Q25, boding well with our <40bps FY26 guidance. This reflects benign asset quality conditions despite geopolitical uncertainty, while our sector-leading coverage across stages provides an additional layer of resilience.

Liquidity

Group deposits increased by +€2.0b yoy to €58.5b in Mar26, comprising nearly 90% of our total net funding. In Greece, deposits were up by +€1.8b yoy to €56.0b, driven by sustained core deposit growth (+€2.0b yoy), leading to a positive mix effect, with more than 80% of our deposits being sight and savings accounts. At the same time, the migration of time deposits to mutual funds remains strong, with retail FuMs increasing by +€2.0b yoy. This trend reflects growing customer appetite for higher-yielding solutions and highlights our ability to successfully capture these flows, delivering impressive market share gains, while supporting fee income generation and optimizing our funding mix and cost.

Our liquidity profile remains robust, manifested by our class leading LCR and L:D ratio of 237% and 69% in Mar26, respectively.

ΕSMA Alternative Performance Measures (APMs), definition of financial data and ratios used

The 1Q26 Results Press Release presents the Financial Results and other basic financial information of National Bank of Greece S.A. (the "Bank") (together with its consolidated subsidiaries (the "Group")) for the period ended 31 March, 2026, and has been prepared, in all material respects, from the underlying accounting and financial records of the Group and the accounting policies applied by the Group in the preparation of its annual financial statements in accordance with International Accounting Standard 34 "Interim Financial Reporting" and International Financial Reporting Standards ("IFRSs"), as endorsed by the EU. The Financial Results and the basic Financial Information presented in this document refer to unaudited financial figures and include the estimates of the Management and provisions relating to financial data or other events of the period ended 31 March, 2026.

The 1Q26 Results Press Release contains financial data, which is compiled as a normal part of our financial reporting and management information systems. For instance, financial items are categorized as foreign or domestic on the basis of the jurisdiction of organization of the individual Group entity, whose separate financial statements record such items. Moreover, it contains references to certain measures which are not defined under IFRS, including "pre-provision income" ("PPI"), "net interest margin" and others, as defined below. These are non-IFRS financial measures. A non-IFRS financial measure is one that measures historical or future financial performance, financial position or cash flows but which excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. The Group believes that the non-IFRS financial measures it presents allow a more meaningful analysis of the Group's financial condition and results of operations. However, the non-IFRS financial measures presented are not a substitute for IFRS measures.

Disclaimer

The information, statements and opinions set out in the Press Release have been provided by National Bank of Greece S.A. (the "Bank") together with its consolidated subsidiaries (the "Group"). They serve informational purposes only and should not be considered as advice or a recommendation to investors or potential investors in relation to holding, purchasing, or selling securities or other financial products or instruments and do not take into account particular investment objectives, financial situation or needs. It is not a research report, a trade confirmation or an offer or solicitation of an offer to buy/sell any financial instruments.

Accuracy of Information and Limitation of Liability

Whilst reasonable care has been taken to ensure that its contents are true and accurate, no representations or warranties, express or implied are given in, or in respect of the accuracy or completeness of any information included in the Press Release. To the fullest extent permitted by law in no circumstances will the Bank, or any of its respective subsidiaries, shareholders, affiliates, representatives, directors, officers, employees, advisers or agents be responsible or liable for any direct, indirect or consequential loss or loss of profit arising from the use of the Press Release, its contents (including the internal economic models), its omissions, reliance on the information contained within it, or on opinions communicated in relation thereto or otherwise arising in connection therewith.

Recipients of the Press Release are not to construe its contents, or any prior or subsequent communications from or with the Bank or its representatives as financial, investment, legal, tax, business, or other professional advice. In addition, the Press Release does not purport to be all-inclusive or to contain all the information that may be required to make a full analysis of the Bank. Recipients of the Press Release should consult with their own advisers and should each make their own evaluation of the Bank and of the relevance and adequacy of the information.

The Press Release includes certain non-IFRS financial measures. These measures are presented in this section under "ESMA Alternative Performance Measures (APMs), definition of financial data and ratios used" and may not be comparable to those of other credit institutions. Reference to these non-IFRS financial measures should be considered in addition to IFRS financial measures but should not be considered a substitute for results that are presented in accordance with IFRS. Due to rounding, numbers presented throughout the Press Release may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figure.

Forward Looking Statements

The Press Release contains forward-looking statements relating to Management's intent, belief, or current expectations with respect to, inter alia, the Bank's businesses and operations, market conditions, results of operation and financial condition, capital adequacy, risk management practices, liquidity, prospects, growth and strategies ("Forward Looking Statements"). Forward Looking Statements concern future circumstances and results and other statements that are not historical facts, sometimes identified by the words "may", "will", "believes", "expects", "predicts", "intends", "projects", "plans", "estimates", "aims", "foresees", "anticipates", "targets", "would", "could" or similar expressions or the negative thereof.

Forward Looking Statements reflect knowledge and information available at the date of the Press Release and are subject to inherent uncertainties and qualifications and are based on numerous assumptions, in each case whether or not identified in the Press Release. Although Forward Looking Statements contained in the Press Release are based upon what Management of the Bank believes are reasonable assumptions, because these assumptions are inherently subject to significant uncertainties and contingencies, including risks that are difficult or impossible to predict and are beyond the Bank's control, no assurance can be provided that the Bank will achieve or accomplish these expectations, beliefs or projections. Risks to the outlook are primarily related to persistent geopolitical tensions at the global level, including the ongoing conflict in the Middle East, which has contributed to renewed upward pressures on energy prices, accelerating inflation, and heightened energy-supply risks. Moreover, a potential resurgence of tariff-related uncertainty, together with a possible re-pricing of risk in global financial markets, could adversely affect investor sentiment and financing conditions. Financial asset valuations could also prove sensitive to uncertainty surrounding AI, particularly if returns on related investments fall short of initial expectations or key assumptions - notably with respect to the future trajectory of monetary policy rates and credit risk premia - deviate materially from baseline scenarios. Moreover, a number of developed and emerging economies are facing increasing fiscal challenges, which could result in abrupt increases in long-term sovereign bond yields, tighter financial conditions, and a rise in debt-servicing burdens. Finally, uncertainty over the scope of actions that may be required by us, governments, and others to achieve goals relating to climate, environmental and social matters, as well as the evolving nature of underlying technological and industrial and governmental standards and regulation.

Therefore, these events constitute additional factors that could cause actual results to differ materially from the ones included in the Forward Looking Statements. Forward Looking Statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. The Bank's actual results may differ materially from those discussed in the Forward Looking Statements. Some important factors that could cause actual results to differ materially from those in any Forward Looking Statements could include, inter alia, changes in domestic and foreign business, market, financial, political and legal conditions including changing industry regulation, adverse decisions by domestic or international regulatory and supervisory authorities, the impact of market size reduction, the ability to maintain credit ratings, capital resources and capital expenditures, adverse litigation and dispute outcomes, and the effect of such outcomes on the Group's financial condition. There can be no assurance that any Forward Looking Statement will be realized, and the Bank expressly disclaims any obligation or undertaking to release any updates or revisions to any Forward Looking Statement to reflect any change in the Bank's expectations with regard thereto or any changes in events, conditions, or circumstances on which any Forward Looking Statement is based. Accordingly, the reader is cautioned not to place undue reliance on Forward Looking Statement.

No Updates

Unless otherwise specified all information in Press Release is as of the date of the Press Release. Neither the delivery of the Press Release nor any other communication with its recipients shall, under any circumstances, create any implication that there has been no change in the Bank's affairs since such date. Except as otherwise noted herein, the Bank does not intend to, nor will it assume any obligation to, update the Press Release or any of the information included herein.

The Press Release is subject to Greek law, and any dispute arising in respect of the Press Release is subject to the exclusive jurisdiction of the Courts of Athens.
