· Domestic NPE stock reduction continues for 10 straight quarters

· NPE stock down €2.4bn during the past 12 months

· Net NPE reduction of €5.6bn since end-Q4.15 reflects organic negative formation (€2.1bn) and write-offs (€3.5bn), c€2bn of which subsequently sold

· NPE and NPL coverage of 60% and 84% combined with NPE and NPL ratios of 43% and 30% in Greece; total coverage including collateral is well above 100% across all business lines

· Q3.18 domestic CoR sustained at 109bps compared with an adjusted for one offs Q2.18 CoR of 107bps

· Domestic deposits reach €40bn

· Domestic deposits continued to increase in Q3.18, driving L:D ratio to 71% in Greece

· Zero impact on liquidity and funding cost from ECB’s waiver removal on the back of NBG issued investment grade covered bonds replacing sovereign bonds

· Eurosystem funding at just €2.3bn from €2.8bn in Q2.18, following the repayment of €0.5bn of TLTRO-I in September

· LCR and NSFR ratios at 124% and 103% respectively, exceeding the 100% regulatory threshold

· CET1 ratio at 16.4%

· CET1 ratio at 16.4% including Banca Romaneasca (BROM) impairment charge

· Pro forma for the 9M.18 PAT and the reduction in RWAs following the completion of South African Bank of Athens (SABA) sale in October, CET1 at 16.6% and 13.1%, taking into account the IFRS 9 full impact

· Group PAT from continuing operations at €48m in 9M.18 against losses of €103m in 9M.17

· Operating profit of €62m in Greece against losses of €100m in 9M.17 is driven by CoR de-escalation (-143bps yoy), fully offsetting core revenue reduction

· Q3.18 domestic NII troughs at €253m (-1% qoq); 9M.18 NII at €776m (-22% yoy) on the back of the IFRS 9 FTA impact, the repricing of part of the mortgage book linked with Greek 12-month T-bills during 1H, as well as restructurings and deleveraging on the retail book

· 9M.18 OpEx at €658m in Greece (+3% yoy), driven by G&As (+7% yoy). The ongoing VRS (>500 FTEs in 2018) is expected to reduce personnel expenses by at least €25m in FY.19

· Domestic PAT from continuing operations at €33m vs losses of €122m in 9M.17

Athens November 29, 2018

Economic conditions are steadily improving in Greece, and these developments should support NBG’s organic profitability as well as organic NPE reduction going forward. It will also facilitate NPE sales, especially as these will include loans with real estate collaterals. Indeed, house prices are up by 3.7% yoy in Q3.18. In this environment NBG’s comparative advantage of a high provision coverage of 60% will allow it to be more aggressive. NBG submitted recently a new NPE strategy to the SSM, committing to a reduction of €10bn by the end of 2021.

Our operating profitability performance in the 9M.18 stood at €84m, contrasting sharply with a loss of €75m in the 9M.17. This notable improvement has been achieved due to a sustainable reduction in credit risk charges to c110bps, after achieving high provision coverage ratios. Following a sharp drop in NII, due to both deleveraging as well as new accounting standards, NII reached a trough in the past two quarters and is expected to begin to recover as corporate lending disbursements accelerate in 4Q to a level in excess of €1bn. At the same time, NII quality has improved retaining a limited reliance on NPE interest. Operating costs will quickly benefit from the ongoing VRS, which will exceed 500 FTEs in 2018 as well as the ongoing programme of branch footprint optimization. Looking ahead, the implementation of the Transformation Programme — to be announced in Q1.19 — will lead profitability to substantially higher levels.

Asset Quality

NPE reduction continues in Q3.18, driven by marginally negative organic NPE formation and reduced write offs. The NPE stock (SSM perimeter) amounted to €15.9bn in Q3.18, with the total NPE reduction achieved since the beginning of the SSM program amounting to €5.6bn. The latter is a function of organic actions driving an NPE reduction of €2.1bn, as well as fully provided write offs (€3.5bn), c€2bn of which were subsequently sold.

The NPE ratio in Greece decreased by 10bps qoq to 42.5% in Q3.18, due to sustained deleveraging, with NPE coverage settling at 59.8%.

Domestic 90dpd formation (SSM perimeter) remained in negative territory in Q3.18 (-€53m from -€199m in Q2.18). Domestic 90dpd ratio settled at 30.4% (flat qoq) on coverage of 83.5% (82.4% at the Group level).

In SE Europe(1), the 90dpd ratio settled at 31.3% on coverage of 63.5%.

Liquidity

Group deposits increased by 1.9% qoq to €42.0bn in Q3.18, driven by the domestic market. Deposits in Greece amounted to €40.0bn on quarterly inflows of €757m. In SE Europe(1), deposits were up by 1.4% qoq to €2.0bn. On an annual basis, Group deposits grew by 8.9% yoy, reflecting deposit inflows of €3.3bn in Greece, despite continuous capital control uplifts.

As a result, NBG’s L:D ratio settled at 71% in Greece (73% in Q2.18) and 72% at the Group level.

Eurosystem amounts to €2.3bn currently from €2.8bn at end-Q2.18, comprising of TLTRO funding from the ECB, with the Bank enjoying a large liquidity buffer. In 9M.18 our LCR and NSFR ratios settled at 124% and 103% respectively, exceeding the minimum regulatory requirement of 100%.

The removal of ECB’s waiver in August 2018 had zero impact on liquidity and funding cost on the back of NBG issued investment grade covered bonds replacing Greek sovereign paper.

Capital

CET1 ratio of 16.4% in Q3.18, including the impairment charge for the sale of Banca Romaneasca, stands comfortably above regulatory requirements.

Pro forma for the 9M.18 PAT and the reduction in RWAs following the completion of SABA sale in October, CET1 stands at 16.6% and 13.1%, taking into account the IFRS 9 full impact.

CET1 ratio

Profitability

Greece:

PAT from continued operations amounted to €33m in 9M.18 against sizable losses of €122m in 9M.17, reflecting mainly the sharp de-escalation in CoR (-143bps yoy), which brought operating result to positive territory (€62m) vs losses in 9M.17 (€100m).

NII amounted to €253m in Q3.18 from €255m the previous quarter, with the impact of restructurings and deleveraging in the retail book largely offset by higher average corporate balances and bond NII. NIM decreased by 7bps qoq to 260bps, reflecting further lending yield drop. In 9M.18, NII declined by 22% yoy to €776m, negatively affected by the IFRS 9 adoption and the one-off impact from the repricing of part of the mortgage book linked with Greek 12-month T-bills during H1.18, as well as the impact of restructurings and deleveraging on the retail book.

Net fee and commission income remained flat qoq at €54m. On an annual basis, net fees grew by 4% yoy, driven by the elimination of ELA-related fees.

Trading income rebounded to €17m in Q3.18 vs the losses of €9m in Q2.18, due to gains of €9m from derivatives vs losses of €4m in Q2.18. In 9M.18, the trading line was positive, generating gains of €43m.

Q3.18 operating expenses amounted to €226m from €220m in Q2.18, reflecting the 6.9% qoq rise in G&As, mainly on increased consulting fees. Personnel expenses remained broadly stable at €137m (+1.0% qoq). On an annual basis, OpEx settled at €658m (+3.0% yoy), driven by G&As (+7.2% yoy) again on higher costs related to professional services. Personel expenses were also up 2.1% yoy, yet incorporated €6.7m arising from the one-off performance-based pay for Special units and a retrospective salary payment. Operating expenses are expected to return to negative growth rates post the completion of the ongoing Voluntary Exit Scheme (VES) benefiting personnel expenses in FY.19, with the full cost borne in Q2.18.

Loan impairments amounted to €78m in Q3.18 from €35m the previous quarter, as the latter was aided by recoveries related to the €2bn unsecured NPL disposal. CoR settled at 109bps from 48bps in Q2.18, yet was stable qoq on a like-for-like basis. 9M.18 CoR settled at 108bps from 251bps in 9M.17, constituting the key driver for our return to operating profitability.

SE Europe: (1)

In SE Europe(1), PAT from continued operations reached €2m in Q3.18 (€3m in Q2.18). At the end of September 2018, PAT from continued operations amounted to €16m from €19m in 9M.17.
