Greece's gas imports correspond to only 1.4% of total euro area consumption - • The amount coming from Russia around 8% of final energy consumption, mainly used for electricity production can be replaced, by a temporary increase in lignite powered electricity plants until LNG and Renewables capacity catches up; renewables already at c40% of electricity generation National Bank of Greece 2Q22 results Key Highlights NATIONAL BANK OF GREECE 8#10NATIONAL BANK OF GREECE 2 Financial Results#11Accelerating core income recovery (+5% yoy) and CoR normalization lift 1H22 COP up 40% to €280m NATIONAL BANK OF GREECE € m 1H22 1H21 YoY 2Q22 QoQ NII 600 596 +1% 312 +8% Net fee & commission income Core Income 170 138 +23% 86 +1% 770 734 +5% 398 +7% Trading & other income 301 449 -33% 181 +50% Total Income 1 072 1 183 -9% 579 +17% Operating Expenses (386) (383) +1% (194) +1% 384 351 +9% 204 +13% 686 800 -14% 385 +28% Loan Impairments (104) (151) -31% (49) -13% Core Operating Profit 280 200 +40% 155 +24% Operating Profit 582 649 -10% 336 +37% Taxes (91) (5) > 100% (54) +44% PAT (cont. ops) 490 645 -24% 282 +36% Disc. ops, minorities & other PAT attributable (69) n/m (96) n/m 546 575 -5% 186 -48% P&L Highlights 1H22 Group PAT (cont. ops.) reaches €490m, supported by solid core operating trends, with COP up by 40% to €280m.

Additionally, it 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. NATIONAL BANK OF GREECE 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.

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 related to increased geopolitical tensions, 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.

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, impact of Covid-19 and the effect of such outcomes on the Group's financial condition.
