(*) Calculated as Reported less the Inventory effects and other non-operating items 32 1Q19 HIGHLIGHTS Good performance despite weaker environment

• Refining margins deteriorated q-o-q and y-o-y – Med complex benchmark refining margins at the lowest level in 4.5 years – Tighter crude availability on supply logistics issues and geopolitical developments leading to negative B-U spread – Higher demand in Greek domestic market due to heating gasoil

• 1Q19 Adj. EBITDA at €123m (-18%) – Reduced refineries utilization due to certain units maintenance shut-downs in 1Q19 – Overperformance sustained at high levels, partly offsetting weaker benchmarks – Strong US$ supported 1Q19 results – New IFRS 16 positive impact of €9m on Adj. EBITDA (mostly Marketing) included in 2019 accounts

• Adj. Net Income at €37m (-40%) with 1Q19 IFRS NI at €47m; further decline in financing costs – IFRS Reported results supported by crude oil price recovery; inventory valuation gains in 1Q at €19m – Like-for-like financing costs further reduced by 16% (excl. IFRS16 impact) – Increased Elpedison profitability drives higher Associates contribution; DESFA no longer included in Group results

• Balance sheet improved vs 1Q18 – Net Debt at €1.5bn and gearing at 38% – Plan to fully repay €325m Eurobond, which matures on 4 July 2019, out of own cash reserves

Forward looking statements HELLENIC PETROLEUM do not in general publish forecasts regarding their future financial results. The financial forecasts contained in this document are based on a series of assumptions, which are subject to the occurrence of events that can neither be reasonably foreseen by HELLENIC PETROLEUM, nor are within HELLENIC PETROLEUM's control. The said forecasts represent management's estimates and should be treated as mere estimates. There is no certainty that the actual financial results of HELLENIC PETROLEUM will be in line with the forecasted ones.

In particular, the actual results may differ (even materially) from the forecasted ones due to, among other reasons, changes in the financial conditions within Greece, fluctuations in the prices of crude oil and oil products in general, as well as fluctuations in foreign currencies rates, international petrochemicals prices, changes in supply and demand and changes of weather conditions. Consequently, it should be stressed that HELLENIC PETROLEUM do not, and could not reasonably be expected to, provide any representation or guarantee, with respect to the creditworthiness of the forecasts.

This presentation also contains certain financial information and key performance indicators which are primarily focused at providing a “business” perspective and as a consequence may not be presented in accordance with International Financial Reporting Standards (IFRS).
