23 Hizmete Özel Key Financials

24 Hizmete Özel Background and definition of key financial KPIs

 In Turkey, Distribution companies operate under a transfer of operating rights (TOR) agreement, which means no legal ownership of assets; legal and asset ownership remains with TEDAŞ (i.e. the state)

 As a consequence, accounting for all Turkish distribution companies falls under IFRIC 12 “service concession arrangements: government or other body grants contracts for supply of public services”

 Therefore, networks are accounted as financial asset instead of fixed assets in IFRS which need to be recognized at fair value under IFRIC 12

 This has two important implications for the presentation of top financial KPIs: 1. IFRS P&L does not show any asset depreciation and accordingly no income from amortisation allowance (reimbursement of capital)  Enerjisa uses EBITDA + Capex reimbursement as its main operational financial KPI to capture the full regulatory, cash-effective RAB return and to increase comparability with international peers who generally do not have to apply IFRIC12 2. Changes in long-term assumptions (e.g. Regulatory parameters) lead to changes in the fair value of the networks-related financial asset. These changes are IFRS P&L-effective, can be material because they relate to the remaining concession period and are fully non cash-effective. As a result they are treated as exceptional items and adjusted from top financial KPIs in order to avoid time series distortions

 As a result, Enerjisa defines the top financial, P&L-related KPIs as follows:

EBITDA + Capex reimbursements Reported Net Income - Exceptional items - Exceptional items = Operational Earnings = Underlying Net Income

25 Hizmete Özel Operational earnings and cash development in 2014 – 2017

Consolidated Operational Earnings Key Drivers (TLm) Distribution

 Higher financial income driven by higher Capex related RAB and higher WACC in 3rd regulatory period +49% 2.565  Higher outperformance on Capex, Opex and T&L driven by 1.938 efficiency gains as well as more favorable regulatory parameters starting in 2016 (theft accrual & collection) 1.100 2.344 Retail 779 1.650 807  Focus on profitable volumes and flexible optimization of 635 customer segments depending on market conditions 145 280 290 247 2014 2015 2016 2017

 Acquisition of license to operate as transfer of operating rights (TOR) agreement Legal  No transfer of legal ownership of assets; legal and asset ownership remains with TEDAŞ

 Accounting for all Turkish distribution companies falls under IFRIC 12 “service concession arrangements: government or other body grants contracts for supply of public services”

 Networks are accounted as financial asset instead of fixed assets in IFRS which need to be recognized at fair value under IFRIC 12; subsequently changes in fair value are recognized through the P&L and are driven by changes in long-term assumptions impacting financial income

 Therefore, IFRS P&L does not show any asset depreciation and accordingly no income from Accounting amortisation allowance (reimbursement of capital)  Enerjisa uses EBITDA and Capex reimbursement as its main KPI to capture the full regulatory RAB return and to increase comparability with international peers

 In contrast, local GAAP accounts for a fixed asset and therefore P&L shows both a depreciation expense as well as reimbursement of capital expenditure as income which is naturally captured in local GAAP EBITDA

 Local GAAP depreciation expense is calculated until end of concession, while Capex reimbursement period is 10 years. Thus, there is a tax correction in place.

 Başkent: 01.09.2036 TOR Period  Toroslar & Ayedaş: 31.12.2042

 Assets are handed back to TEDAŞ in exchange of reimbursement of unamortised RAB Expiration  A new re-tender of the asset may follow  “Liberalised” retail license is not in the scope of TOR

68 Hizmete Özel Price equalisation mechanism

• EMRA determines the revenue and price caps for distribution and retail companies in each region • Price equalisation mechanism was introduced to balance the inequalities and differences between the 21 distribution regions - Mechanism was determined for inequalities in regional characteristics like distribution of customer segments, theft & loss occurrences and performances - Mechanism was implemented as a result of application of a single tariff throughout Turkey • Price equalisation mechanism makes sure that the distribution companies and the incumbent retail companies obtain their regulated returns, although they charge the same end tariff. • EMRA sets the regulated margin and revenue requirements for regulated sales based on demand and consumption forecasts. However, the actual demand of customers shows some variance from forecasts which leads to imbalances in our electricity purchases. • EMRA compensates for such variances via the price equalisation mechanism two quarters after the occurrence of such variances and guarantees that the incumbent retail company generates a gross margin of 2.38%, independent of its sourcing costs for its regulated customers. • Reconciliation of over or under collections is made by EMRA through TETAŞ on a monthly basis.
