Eni: fourth quarter and full year 2021 results

Eni's Board of Directors, chaired by Lucia Calvosa, yesterday approved the unaudited consolidated results for the full year and the fourth quarter of 2021. Eni CEO Claudio Descalzi said:

“During 2021, we delivered excellent results and accelerated the pace of our transformation strategy, which leverages the integration of technologies, new business models and valuable relationships with our stakeholders. The strict financial discipline and cost efficiencies we implemented to withstand the downturn have allowed us to best capture the strong economic recovery of 2021. On the one hand, our upstream segment has kept generating the financial resources needed to fund our decarbonization strategy while, on the other, the new energy transition businesses, like those combined under our new entity Plenitude, have performed strongly. In this way, we have reached a Group EBIT of €9.7 bln and adjusted net profit of €4.7 bln, our best performance since 2012, a time when Brent crude oil prices exceeded the $110-a-barrel mark. Robust cash generation, underpinned by a selective approach to making investment decisions, has freed €7.6 bln of organic free cash flow, which we used to: boost the growth of green businesses; fund dividends and a share buy-back at pre-pandemic levels; and deleverage the balance sheet - achieving an indebtedness ratio of 20% vs 31% a year ago. Our portfolio restructuring has moved on to unlock value from our businesses, optimize our cost of capital and maximize growth. The listing of Plenitude, which combines renewables, customers and e-mobility, will enable us to fulfil our goal of cutting Scope 3 emissions for our retail customers. The upstream portfolio has also proven to be a value driver in the energy transition, as demonstrated by the success of the Vår Energi listing on the Norwegian stock exchange, the largest IPO of an O&G company of the last decade, as well as the upcoming creation of a strategic joint venture in Angola with BP that will combine the two partners’ operations in the Country. Finally, we are developing a full range of solutions to reduce GHG emission for our plants and industrial clients through: the HyNet CCS project in the UK; agro-biofeedstock hubs to supply our refineries; and the successful magnetic fusion test performed by CFS of which we are the main shareholder. All in all, our performance in 2021 highlighted the efficacy of the strategy launched at the start of the pandemic, which enabled us to return to pre-crisis balance sheet strength in just a few months while simultaneously enhancing our transition plans.”

Q4 2021 scenario

In the fourth quarter of 2021, the Brent price averaged 80 $/bbl, up 9% sequentially and almost double YoY. In January 2022, the Brent price reached its highest level since 2014.

Q4 2021 financial highlights

The Group financial outlook, its business prospects and the key industrial and profitability targets in the short, medium and long term will be disclosed during the Capital Markets Day scheduled on March 18, 2022. A press release illustrating the Group’s strategy will be issued on the same day and disseminated through the Company’s website (eni.com) and other public channels as required by applicable listing standards.

Exploration & Production

Growth was fueled by continued production ramp-ups at the giant Zohr (Egypt) and Merakes (Indonesia) gas fields, with the latter achieving first gas last April.

In the full year 2021, production fell compared to the full year 2020 due to greater maintenance activity (in Norway, Italy and the UK), lower activity in Nigeria and mature fields decline.

Start-ups and ramp-ups added 70 kboe/d (on average in the full year of 2021) mainly due to Merakes in Indonesia, Berkine in Algeria, the Mahani gas project in the Sharjah Emirate (UAE), as well as the tie-in of the satellite discoveries of Cuica and Cabaca North in Block 15/06, offshore Angola.

¹ It includes the estimated Vår Energi result for the fourth quarter of 2021.

In the full year of 2021, the adjusted operating profit was €9,303 million, an increase of €7.8 billion compared to the same period of 2020 (up 501%) due to materially higher realized prices (up 80% and 77% vs. the full year of 2020 for liquids and gas, respectively) partly offset by lower production volumes.

Adjusted results

Special items

The breakdown of special items recorded in operating profit by segment (a net gains of €1,083 million in the full year of 2021, €1,406 million in the fourth quarter 2021) is as follows:

In the full year the reclassification to adjusted operating profit of the positive balance of €206 million (€52 million in the quarter) related to derivative financial instruments used to manage margin exposure to foreign currency exchange rate movements and exchange translation differences of commercial payables and receivables.

The other special items in the fourth quarter of 2021 were related to: (i) impairment reversals of equity investments related to joint ventures in the E&P segment; (ii) alignment with the current values of the raw materials and products inventory as well as write-downs and extraordinary charges of the ADNOC refinery.

Net borrowings and cash flow from operations

Net cash provided by operating activities for the full year of 2021 was €12,851 million, an increase of €8 billion compared to the full year of 2020, driven by a better scenario in the upstream segment.

The cash flow benefitted from trade receivables (€2 billion) due in subsequent reporting periods divested to financing institutions, up by approximately €0.7 billion compared to the fourth quarter 2020.

The outflow related to the working capital of approximately €3.2 billion was due to the change in the value of inventory holding, the use of advances received by Egyptian state-owned companies for financing the Zohr project, which were netted against invoices for gas supplies and the adjustment of the derivatives fair value.

The dividends received by equity investments mainly related to Vår Energi.

Cash flow from operations before changes in working capital at replacement cost was €12,713 million. This non-GAAP measure includes net cash provided by operating activities before changes in working capital excluding inventory holding gains or losses relating to oil and products and provisions for extraordinary credit losses and other charges, as well as the fair value of commodity derivatives lacking the formal criteria to be designated as hedges.

A reconciliation of cash flow from operations before changes in working capital at replacement cost to net cash provided by operating activities for the fourth quarter and the full year of 2021 and 2020 is provided below:

Organic capex was €5.8 billion, in line with the guidance, and included the utilization of trade advances cashed by Egyptian partners in previous reporting periods in relation to the financing of the Zohr project (approximately €500 million). They were fully funded by the adjusted cash flow.

Cash outflows for acquisitions net of divestments were €2.1 billion (to which €0.8 billion of net finance debt are to added) and related to the acquisition of a 20% stake in the Dogger Bank A/B offshore wind project in the North Sea, the 100% stake in Aldro Energía in the retail gas business, the 100% stake in Fri-El Biogas Holding engaged in the bioenergy business in Italy, a company engaged in the installation and management of a network of charging stations for electric vehicles, Be Power, for which half of the price will be paid in 2022, as well as a portfolio of renewables assets operational/under construction in Italy (wind power assets) and in Spain and France (operations related to Dhamma Energy Group and Azora Capital with wind and photovoltaic assets).

Net financial borrowings before IFRS16 decreased by around €2.6 billion mainly due to issuances of hybrid bonds for €2 billion and the free cash flow provided by operating activities (approximately €5.6 billion), partly offset by the payment of dividends to Eni’s shareholders of approximately €2.4 billion (the 2020 balance dividend of €0.24 per share for a total amount of approximately €0.8 billion and the 2021 interim dividend of €0.43 per share for a total amount of €1.5 billion), the €400 million buy-back program, the payment of lease liabilities for €0.9 billion and the consolidation of debt of acquired subsidiaries (€0.8 billion).

As of December 31, 2021, fixed assets of €74.6 billion increased by €4.7 billion from December 31, 2020: capital expenditures and acquisitions during the period and the positive impact of exchange rate differences were partly offset by DD&A (the period-end exchange rate of EUR vs. USD was 1.133, down 7.7% compared to 1.227 at December 31, 2020).

Net working capital (-€14.8 billion) was substantially unchanged compared to December 31, 2020: the increased value of oil and product inventories due to the weighted-average cost method of accounting in an environment of rising prices were partly offset by the recognition of income taxes for the period of €1.6 billion and by the increase of the other current assets and liabilities (€0.7 billion).

Shareholders’ equity (€44.8 billion) increased by approximately €7.3 billion compared to December 31, 2020 due to the net profit for the period (€6.15 billion), the issuance in May, 2021 of hybrid bonds for €2 billion and positive foreign currency translation differences (about €2.83 billion) reflecting the appreciation of the US dollar vs. the euro as of December 31, 2021 vs. December 31, 2020, partly offset by the payment of dividends to Eni shareholders (balance dividend 2020 of €0.86 billion and the 2021 interim dividend of €1.53 billion), the buy-back (€0.4 billion) as well as a negative change in the cash flow hedge reserve of €1.26 billion reflecting trends in gas prices.

Net borrowings² before lease liabilities as of December 31, 2021 were €8.99 billion, down €2.58 billion from December 31, 2020. Leverage³ – the ratio of the borrowings to total equity calculated before the impact of IFRS 16 - was 0.20 at December 31, 2021, lower than December 31, 2020 (0.31).

² Details on net borrowings are furnished on page 29.

Disclaimer

This press release contains certain forward-looking statements particularly those regarding capital expenditure, development and management of oil and gas resources, dividends, share repurchases, allocation of future cash flow from operations, future operating performance, gearing, targets of production and sales growth, new markets and the progress and timing of projects. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that will or may occur in the future. Actual results may differ from those expressed in such statements, depending on a variety of factors, including the impact of the pandemic disease, the timing of bringing new fields on stream; management’s ability in carrying out industrial plans and in succeeding in commercial transactions; future levels of industry product supply; demand and pricing; operational issues; general economic conditions; political stability and economic growth in relevant areas of the world; changes in laws and governmental regulations; development and use of new technology; changes in public expectations and other changes in business conditions; the actions of competitors and other factors discussed elsewhere in this document. Due to the seasonality in demand for natural gas and certain refined products and the changes in a number of external factors affecting Eni’s operations, such as prices and margins of hydrocarbons and refined products, Eni’s results from operations and changes in net borrowings for the quarter of the year cannot be extrapolated on an annual basis.

The all sources reserves replacement ratio disclosed elsewhere in this press release is calculated as ratio of changes in proved reserves for the year resulting from revisions of previously reported reserves, improved recovery, extensions, discoveries and sales or purchases of minerals in place, to production for the year. A ratio higher than 100% indicates that more proved reserves were added than produced in a year. The reserves replacement ratio (RRR) is a measure used by management to indicate the extent to which production is replaced by proved oil and gas reserves. The RRR is not an indicator of future production because the ultimate development and production of reserves is subject to a number of risks and uncertainties. These include the risks associated with the successful completion of large-scale projects, including addressing ongoing regulatory issues and completion of infrastructure, as well as changes in oil and gas prices, political risks and geological and other environmental risks.

Adjustments to preliminary results will follow the accounting of Saipem’s result for the fourth quarter, the adjustment for the accounting of Vår Energi’s result for the fourth quarter and the completion of the approval of Eni four-year strategic plan.

This press release for the fourth quarter and the full year of 2021 results (not subject to audit) is also available on Eni’s website eni.com.

Management evaluates underlying business performance on the basis of Non-GAAP financial measures, which are not provided by IFRS (“Alternative performance measures”), such as adjusted operating profit, adjusted net profit, which are arrived at by excluding from reported results certain gains and losses, defined special items, which include, among others, asset impairments, including impairments of deferred tax assets, gains on disposals, risk provisions, restructuring charges, the accounting effect of fair-valued derivatives used to hedge exposure to the commodity, exchange rate and interest rate risks, which lack the formal criteria to be accounted as hedges, and analogously evaluation effects of assets and liabilities utilized in a relation of natural hedge of the above mentioned market risks. Furthermore, in determining the business segments’ adjusted results, finance charges on finance debt and interest income are excluded (see below). In determining adjusted results, inventory holding gains or losses are excluded from base business performance, which is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting as required by IFRS, except in those business segments where inventories are utilized as a lever to optimize margins.

Finally, the same special charges/gains are excluded from the Eni’s share of results at JVs and other equity accounted entities, including any profit/loss on inventory holding.

Management is disclosing Non-GAAP measures of performance to facilitate a comparison of base business performance across periods, and to allow financial analysts to evaluate Eni’s trading performance on the basis of their forecasting models.

Non-GAAP financial measures should be read together with information determined by applying IFRS and do not stand in for them. Other companies may adopt different methodologies to determine Non-GAAP measures.

Follows the description of the main alternative performance measures adopted by Eni. The measures reported below refer to the performance of the reporting periods disclosed in this press release:

Adjusted operating and net profit

Adjusted operating profit and adjusted net profit are determined by excluding inventory holding gains or losses, special items and, in determining the business segments’ adjusted results, finance charges on finance debt and interest income. The adjusted operating profit of each business segment reports gains and losses on derivative financial instruments entered into to manage exposure to movements in foreign currency exchange rates, which impact industrial margins and translation of commercial payables and receivables. Accordingly, also currency translation effects recorded through profit and loss are reported within business segments’ adjusted operating profit. The taxation effect of the items excluded from adjusted operating or net profit is determined based on the specific rate of taxes applicable to each of them.

Finance charges or income related to net borrowings excluded from the adjusted net profit of business segments are comprised of interest charges on finance debt and interest income earned on cash and cash equivalents not related to operations. Therefore, the adjusted net profit of business segments includes finance charges or income deriving from certain segment operated assets, i.e., interest income on certain receivable financing and securities related to operations and finance charge pertaining to the accretion of certain provisions recorded on a discounted basis (as in the case of the asset retirement obligations in the Exploration & Production segment).

Inventory holding gain or loss

This is the difference between the cost of sales of the volumes sold in the period based on the cost of supplies of the same period and the cost of sales of the volumes sold calculated using the weighted average cost method of inventory accounting as required by IFRS.

Special items

These include certain significant income or charges pertaining to either: (i) infrequent or unusual events and transactions, being identified as non-recurring items under such circumstances; (ii) certain events or transactions which are not considered to be representative of the ordinary course of business, as in the case of environmental provisions, restructuring charges, asset impairments or write ups and gains or losses on divestments even though they occurred in past periods or are likely to occur in future ones. Exchange rate differences and derivatives relating to industrial activities and commercial payables and receivables, particularly exchange rate derivatives to manage commodity pricing formulas which are quoted in a currency other than the functional currency are reclassified in operating profit with a corresponding adjustment to net finance charges, notwithstanding the handling of foreign currency exchange risks is made centrally by netting off naturally-occurring opposite positions and then dealing with any residual risk exposure in the derivative market. Finally, special items include the accounting effects of fair-valued commodity derivatives relating to commercial exposures, in addition to those which lack the criteria to be designed as hedges, also those which are not eligible for the own use exemption, including the ineffective portion of cash flow hedges, as well as the accounting effects of settled commodity and exchange rates derivatives whenever it is deemed that the underlying transaction is expected to occur in future reporting periods.

Correspondently, special charges/gains also include the evaluation effects relating to assets/liabilities utilized in a natural hedge relation to offset a market risk, as in the case of accrued currency differences at finance debt denominated in a currency other than the reporting currency, where the cash outflows for the reimbursement are matched by highly probable cash inflows in the same currency. The deferral of both the unrealized portion of fair-valued commodity and other derivatives and evaluation effects are reversed to future reporting periods when the underlying transaction occurs.

As provided for in Decision No. 15519 of July 27, 2006 of the Italian market regulator (CONSOB), non-recurring material income or charges are to be clearly reported in the management’s discussion and financial tables.

Leverage

Leverage is a Non-GAAP measure of the Company’s financial condition, calculated as the ratio between net borrowings and shareholders’ equity, including non-controlling interest. Leverage is the reference ratio to assess the solidity and efficiency of the Group balance sheet in terms of incidence of funding sources including third-party funding and equity as well as to carry out benchmark analysis with industry standards.

Gearing

Gearing is calculated as the ratio between net borrowings and capital employed net and measures how much of capital employed net is financed recurring to third-party funding.

Cash flow from operations before changes in working capital at replacement cost

This is defined as net cash provided from operating activities before changes in working capital at replacement cost. It also excludes certain non-recurring charges such as extraordinary credit allowances and, considering the high market volatility, changes in the fair value of commodity derivatives lacking the formal criteria to be designed as hedges, including derivatives which were not eligible for the own use exemption, the ineffective portion of cash flow hedges, as well as the effects of certain settled commodity derivatives whenever it is deemed that the underlying transaction is expected to occur in future reporting periods.

Free cash flow

Free cash flow represents the link existing between changes in cash and cash equivalents (deriving from the statutory cash flows statement) and in net borrowings (deriving from the summarized cash flow statement) that occurred from the beginning of the period to the end of period. Free cash flow is the cash in excess of capital expenditure needs. Starting from free cash flow it is possible to determine either: (i) changes in cash and cash equivalents for the period by adding/deducting cash flows relating to financing debts/receivables (issuance/repayment of debt and receivables related to financing activities), shareholders’ equity (dividends paid, net repurchase of own shares, capital issuance) and the effect of changes in consolidation and of exchange rate differences; (ii) changes in net borrowings for the period by adding/deducting cash flows relating to shareholders’ equity and the effect of changes in consolidation and of exchange rate differences.

Net borrowings

Net borrowings is calculated as total finance debt less cash, cash equivalents and certain very liquid investments not related to operations, including among others non-operating financing receivables. Financial activities are qualified as “not related to operations” when these are not strictly related to the business operations.
