Information on the Assurance Statement

The Assurance Provider TÜV AUSTRIA Hellas (‘the Provider’) has been engaged to provide external assurance on the disclosures published in the Corporate Sustainability and Social Responsibility Report 2018 (‘the Report’) of Hellenic Petroleum Group (‘the Company’).

1. Reviewed the Report against the requirements of GRI’s set of Sustainability Reporting Standards and confirmation that the “Comprehensive option” requirements are fulfilled.
2. Verification of the data included in all the chapters of the Report.
3. Site visits at the Company’s Head Offices in Marousi and its refineries located in Aspropyrgos, Eleusina and Thessaloniki, for the implementation of verification and sampling inspections of files in order to evaluate:

• the reliability and accuracy of performance indicators of the Sustainability Report
• the reliability of processes for generating, gathering and managing information included in the Report.

Conclusions

During the assurance engagement, it was confirmed that the data and information are reliable. The accuracy of the disclosed statements and assertions was found to be within acceptable limits. The Company provided a comprehensive and proper presentation of performance on the basis of reasonably documented information as well as that there is an effective data gathering, management and reporting system in place for issues which pertain to sustainable development. The Provider concurs that the GRI STANDARDS “Comprehensive option” requirements have been met, including the Oil and Gas Sector Supplement.

Opportunities for Improvement

Based on the observations and concluding remarks derived from the assurance engagement, the Provider’s recommendations for the improvement of the Company’s future Sustainability Reports are as follows:

• Harmonize the procedures and data collection systems of all companies within the boundaries of the Report.
