FINANCIAL REPORT

2017 RESULTS

Consolidated financial information audited by independent auditors, prepared in accordance with International Financial Reporting Standards - IFRS.

Rio de Janeiro – March 15 ^th , 2018

▪

Results

Petrobras reported a loss of R$ 446 million in 2017, determined by the following factors:

o	class action Agreement in the USA, in the amount of R$ 11,198 million; and

o	Adhesion to Brazilian federal settlement programs, totaling R$ 10,433 million.

Compared to 2016, there was an improvement in the operating profit due to the following factors:

o	Higher net exports of oil at higher prices;

o	Reduced personnel costs;

o	Lower expenses with dry wells and equipment idleness;

o	Gain from the sale of NTS in 2Q-2017 ; and

o	Lower impairment and depreciation of assets.

Excluding the class action agreement, the Company would have presented net income of R$ 7,089 million.

Free Cash Flow* remained positive for the eleventh consecutive quarter, reaching R$ 44,064 million in 2017, 6% higher than the previous year. This result reflects the reduction in investments.

▪	Metric - Net Debt / Adjusted EBITDA

Net debt* reached R$ 280,752 million or US$ 84,871 million, representing a decrease of 11% and 12% respectively, compared to 2016. In addition, liability management made it possible to increase the average duration of 7.46 years to 8.62 years, simultaneously with the reduction of the average rate of 6.2% p.a. to 6.1% p.a..

Adjusted EBITDA* decreased by 14% in 2017 to R$ 76,557 million and the Adjusted EBITDA Margin* was 27%, due to the above mentioned factors (class action agreement and Brazilian federal settlement agreements).

In view of that, the net debt to Adjusted EBITDA* ^* ratio reached 3.67 in 12/31/2017, after having reached 3.16 as of 09/30/2017. Leverage* decreased from 55% to 51% in the year.

Excluding the class action effect, Adjusted EBITDA would be R$ 87,755 million and the net debt/Adjusted EBITDA index would reach 3.20.

▪	Operating highlights

Total crude oil and natural gas production reached 2,767 thousand barrels of oil equivalent per day (boed) in 2017, being 2,655 thousand boed in Brazil, stable compared to 2016.

Output of domestic oil products in Brazil decreased by 5% while its sales dropped 6% when compared to 2016, to 1,800 thousand bpd and 1,940 thousand bpd respectively.

The Company sustained the position of net exporter, with 361 thousand bpd of balance in 2017 (vs. 167 thousand bpd in 2016), due to the increase in exports of 32% and reduction in imports of 18%

2017 x 2016 Results * :

The Company improved its operational profit in 2017, due to the increase in Brent prices, as well as in volume and margin of oil exports and increase in natural gas sales, reduction in personnel expenses and with costs attributable to writ-offs of dry and/or subcommercial wells and to equipment idleness, gains with the sale of NTS and drop in impairment and in depreciation. On the other hand, there were lower volumes of oil products sales in the domestic market and higher expenses with government participation. Altogether those factors resulted in an operating income of R$ 35,624 million, 108% higher than 2016.

During 2017, with the objective of eliminating risks and uncertainties related to litigation, the Company signed an agreement to finish the class action, in the total amount of R$ 11,198 million (including taxes), and joined four Brazilian federal settlement programs, which affected the Company’s results, generating a net loss of R$ 446 million and a reduction of the Adjusted EBITDA, from R$ 88,693 million in 2016 to R$ 76,557 million in 2017.

The Brazilian federal settlement programs also affected the net finance expenses, being offset by the reduction in interest expenses, as a result of the liability management, that reduced debt’s amount and cost. However, the higher depreciation of dollar over the net negative exposure in pound and euro in the period led to worse financial result.

Free Cash Flow increased 6%, in view of the reduction in investments.

4Q-2017 Results**:

In the 4Q-2017, there was improvement in the margins, both in exports and in domestic sales, as a result of the increase in Brent prices and of the pricing policy, contributing to a gross profit 19% higher (R$ 25,203 million), despite the lower sales volume.

On the other hand, the Company signed the agreement to finish the class action and adhered to the tax settlement program related to administrative and judicial disputes related to income tax. Those agreements resulted in increase of operational expenses, reflecting the fall of 32% in Adjusted EBITDA, totaling R$ 12,986 million in the quarter.

Those agreements, in conjunction with the impairment, in the amount of R$ 3,511 million, led to the net loss of R$ 5,477 million.

Free Cash Flow was positive for the eleventh quarter in a row, reaching R$ 6,608 million. Despite higher margins in the domestic sales and exports, the operating cash flow was affected by the increase in judicial deposits, resulting in its reduction by 19%. Besides that, investments were 40% higher due to the signature bonuses related to the last three ANP Bidding Rounds.

RESULT BY BUSINESS SEGMENT

EXPLORATION & PRODUCTION

2017 x 2016		4Q-2017 x 3Q-2017
Results
Gross profit increased due to higher oil Brent prices, lower costs with depreciation, partially offset by increase in production taxes. This improvement in the operational performance, together with lower impairment expenses and lower equipment idleness, resulted in the increase of operational income.		Higher oil prices led to revenues increase and, on the other hand, to a rise production taxes, resulting in higher gross profit. Operating income was even better, due to the gains with the revaluation of costs forecast related to abandonment and reversal of impairment. These factors were offset by the decision to join the tax settlement program related to income tax.

Operating Results

Production

Domestic crude oil and NGL production remained stable.

Natural gas production increased 3% mainly due to the start-up of production of P‑66 and the ramp-up of FPSOs Cid. de Saquarema, Cidade de Maricá and Cidade de Itaguaí.

The production of crude oil, NGL and natural gas abroad declined due to PESA’s sale in 2016.

Domestic crude oil and NGL production remained stable.

Domestic natural gas production decreased 2% due to more interventions on onshore fields compressions systems.

International crude oil, NGL and natural gas production reduced due to operational reasons in the USA mainly related to the Hadrian South filed that stopped production on October/2017.

Lifting Cost

Lifting cost increased mainly due to the foreign exchange effects related to expenses denominated in Brazilian Real.

Additionally, higher production taxes were caused by higher oil prices and increased pre-salt production.

The indicator in US dollar decreased due to the apreciation of the domestic currency in the costs .

Additionally, there were higher production taxes caused by the increase in oil prices.

Lifting cost abroad increased mainly in the U.S.A, due to higher interventions in Lucius field.

REFINING, TRANSPORTATION AND MARKETING

2017 x 2016		4Q-2017 x 3Q-2017
Results
Gross profit decreased mainly due to reduction of margins, mainly diesel and gasoline, higher Brent and domestic oil prices, as well as reduction in oil products sales volume in the domestic market. The operating profit also reduced, although there has been reduction in expenses associated with sales, voluntary separation plan and impairment.		The increase in gross profit is due to higher revenues in the domestic market, mainly with gasoline and LPG, impacted by the pricing policy, as well as higher oil products exports. On the other hand, the appreciation of Brent had a lower impact on costs due to inventories formed at lower prices. Operating income increased less due to the impact of impairment.

Operating Performance

Imports and Exports of Crude Oil and Oil Products

Net crude oil exports increased because of decrease in volume processed in refineries, both domestic and imported.

The reduction in net oil products imports, especially diesel and gasoline, is due to lower domestic sales along with the increase in market share of our competitors in the Brazilian market.

Net crude oil exports decreased because of ongoing exports.

The improvement in the net balance of oil products was due to the reduction in imports, mainly of diesel and naphtha, and in the increase of exports, mainly of diesel and gasoline.

Refining Operations

Processed feedstock was lower, mainly due to increase in imports by third parties.

Processed feedstock remained stable.

Refining Cost
Refining cost was higher mainly reflecting a decrease in processed feedstock.		Refining cost decreased to lower personnel expenses and third party services.

GAS & POWER

2017 x 2016

4Q-2017 x 3Q-2017

Results

Gross profit was higher due to increase in natural gas sales and in the participation of national gas in the sales mix. Those factors, aligned with to the gain with the sale of Company’s interest in NTS resulted in higher operating income, partially offset by lower impairment.

The increase of gross profit was due to higher margins with energy, natural gas and LPG sales. Despite this, there was operating loss due to decrease in impairment.

Operating Performance

Physical and Financial Indicators

The increase in the national gas supply led to reduction in imports of natural gas from Bolivia and of LNG.

Electric generation rose due to the reduction in hydrologic volume, which led to higher prices in the spot market.

The increased supply of domestic gas made it possible to reduce imports of Bolivian natural gas.

The reduction of energy sales in the Free Contracting Environment (ACL) occurred due to the seasonal demand and the reduction of energy generation was a reflection of the improvement of the hydrological conditions.

DISTRIBUTION

2017 x 2016		4Q-2017 x 3Q-2017
Results
The decrease in gross profit reflected the drop in sales and market share, mainly due to the lower volume sold to the thermoelectric plants, as well as the greater competition of regional players, partially offset by the increase in margins. The operating income increased mainly reflecting the lower losses with receivables from the electricity sector, with administrative and judicial claims, as well as the reversal of expenses with voluntary separation plan, provisioned in 2016		Gross profit remained stable, reflecting the increase in sales margins offset by the reduction in sales volume. The operating income reduced due to the effects of adherence to a tax settlement agreement, associated with the reversal of tax credits provision in JET A1 commercialization in Bahia, due to the change in legislation, both occurred in the last quarter.

Operating Performance

The market share reduction is due to the decrease in the diesel sales volume, mainly to thermoelectric plants, result of the maintenance of the policy to keep the margins and maximize profitability, which led to a higher sales selectivity. Besides that, there was an increase in competition in the oil products markets, associated with lower direct consumer market.

The reduction in market share is explained by the drop in sales of diesel, mainly in the consumer segment. It was verified, an increase in competition, associated with the reduction of the direct consumer market.

ADDITIONAL INFORMATION

Reconciliation of Adjusted EBITDA

Our Adjusted EBITDA is a performance measure computed by using the EBITDA (net income before net finance income (expense), income taxes, depreciation, depletion and amortization). Petrobras presents the EBITDA according to Instrução CVM nº 527 of October 4, 2012, adjusted by items not considered as part of Company’s primary business, which include results in equity-accounted investments, impairment, cumulative foreign exchange adjustments reclassified to the income statement and results from disposal and write-offs of assets.

The LTM Adjusted EBITDA reflects the sum of the last twelve months of Adjusted EBITDA and represents an alternative measure to our net cash provided by operating activities. This measure is used to calculate the metric Net Debt/LTM Adjusted EBITDA, which is established in the Business Plan 2018-2022, to support management’s assessment of liquidity and leverage.

EBITDA, Adjusted EBITDA and LTM Adjusted EBITDA are not defined in the International Financial Reporting Standards – IFRS. Our calculation may not be comparable to the calculation of Adjusted EBITDA by other companies and it should not be considered as a substitute for any measure calculated in accordance with IFRS. These measures must be considered in conjunction with other measures and indicators for a better understanding of the Company's operational performance and financial conditions.

The reclassification of foreign exchange variation expense from Shareholders’ Equity to the Income Statement in 2017 was R$ 10,067 million, a reduction of 1% compared to 2016 due to the exchange rate.

The higher reclassification of foreign exchange variation expense from OCI to the Statement of Income in the 4Q-2017 was R$ 2,692 million, compared to the 3Q-2017 (R$ 2,569 million), mainly as a result of the occurrence of hedged transactions (exports hedged by debt denominated in U.S. dollars), with higher spread of foreign exchange rate (R$/US$) between the date the cash flow hedge relationship was designated and the date the export transactions were made.

Additional hedging relationships may be revoked or additional reclassification adjustments from equity to the income statement may occur as a result of changes in forecast export prices and export volumes following a review of the Company’s business plan. Based on a sensitivity analysis considering a US$ 10/barrel decrease in Brent prices stress scenario, when compared to the Brent price projections in our most recent update of the 2018-2022 Business and Management Plan ( Plano de Negócios e Gestão – PNG), no reclassification adjustment from equity to the income statement would occur.

The expected annual realization of the foreign exchange variation balance in shareholders’ equity, on December 31, 2017, is set out below:

ADDITIONAL INFORMATION

Assets and Liabilities subject to Exchange Variation

The Company has assets and liabilities subject to foreign exchange rate variation, for which the main gross exposures are the Brazilian Real relative to the U.S. dollar and the U.S. dollar relative to the Euro. Beginning in mid-May 2013, the Company extended the use of hedge accounting to hedge highly probable future exports.

The Company designates hedging relationships between exports and its long-term debt obligations (denominated in U.S. dollars) to, simultaneously, recognize the effects of the existing natural foreign exchange hedge between those operations in its financial statements. Through the extension of the hedge accounting practice, foreign exchange gains or losses, generated by foreign exchange variation, are recognized in our shareholders’ equity and will only affect the statement of income at the moment of future exports realization.

During 2017, Petrobras, through its affiliate Petrobras Global Trading B.V. (PGT), made a cross currency swap derivative, aiming to protect the exposure to pounds against U.S. dollar, in view of the bond with notional value of GBP 700 million and GBP 600 million with maturity to December, 2026 and 2034 respectively. The Company does not have the intention to liquidate those transactions before the maturity date.

The balances of assets and liabilities in foreign currency of our foreign subsidiaries are not included in our foreign exchange rate variation exposure below when transacted in a currency equivalent to their respective functional currencies.

As of December 31, 2017, the Company had a net liability exposure to foreign exchange rates, of which the main exposure is the relationship between the U.S. dollar and the euro.

ADDITIONAL INFORMATION

2017 compared to 2016:

Sales revenues of R$ 283,695 million, an R$ 1,106 increase when compared to 2016 (R$ 282,589 million), due to:

•

Higher export revenues (R$ 12,814 million), mainly due to the increase in crude oil volume exported as a result of a higher availability due to lower domestic demand of oil products because of higher placement by importers in the domestic market. The higher international prices of crude oil and oil product was also a contributing factor to the increase in export revenues.

•	Lower revenues from operations abroad (R$ 10,789 million), due to the disposal of interests in Petrobras Argentina S.A. (PESA) and in Petrobras Chile Distribución Ltda (PCD); and

•	Decreased domestic revenues (R$ 919 million), as a result of:

✓

Lower oil products revenues, due to increase in imports from third parties, mainly for diesel (R$ 7,339 milhões) and gasoline (R$ 2,610 milhões);

✓

Increased eletricity revenues (R$ 4,805 million), due to higher thermoelectric dispatches, at higher prices in the spot market, because of worse hydrological conditions;

✓

Higher natural gas sales to attend the increase of thermoelectric dispatches, with higher prices (R$ 2,738 million); and

✓

higher average price of oil products, highlighting the readjustment of LPG prices (R$ 2,059 million), Jet Fuel reflecting the increase in international prices (R$ 1,146 million) partially offset by the reduction of diesel prices (R$ 1,418 million) and gasoline (R$ 396 million).

Cost of sales were R$ 192,100 million, R$ 511 million lower than 2016 (R$ 192,611 million), reflecting:

•	Decreased depreciation expenses, as a result of the impairment provision expenses occurred in 2016;

•	Lower import costs of oil and oil products due to the increase in domestic crude oil share on the feedstock processed and the lower oil product sales volume in the domestic market and of natural gas, as a result of the higher participation of the domestic natural gas in the sales mix;

•	Decreased costs from operations abroad mainly attributable to the sale of PESA and Petrobras Chile.

•	Higher production taxes due to the increase in international prices and higher production from Lula field that has a higher Special Participation Tax rate;

•	Increased electricity expenses, because of higher prices in the spot market.

Selling expenses were R$ 14,510 million, a 5% increase compared to 2016 (R$ 13,825 million), influenced by the increase in logistical expenses due to the use of gas pipelines since the sale of NTS, partially offset by the lower allowance for doubtful accounts receivable from the electricity sector and the effect of the divestment of PESA and PCD.

General and administrative expenses were R$ 9,314 million, a 19% decrease compared to R$ 11,482 million in 2016, mainly due to lower personnel expenses, attributable to the separations of employees due to the Voluntary Separation Incentive Plan 2014/2016 and to lower third-party service expenses, mainly related to administrative services.

Exploration costs were R$ 2,563 million, a 58% decrease compared to 2016 (R$ 6,056 million), mainly due to lower exploration expenditures written off as dry hole or sub-commercial wells (R$ 3,471 million).

Tax expenses were R$ 5,921 million, which were R$ 3,465 million higher compared to 2016 (R$ 2,456 million), mainly as a result of the Company’s decision to adhere to the Tax Settlement Programs (R$ 2,841 million).

Other operating expenses of R$ 17,970 million 2017, a 6% increase compared to 2016 (R$ 16,925), mainly due to:

•	Higher provision for losses and contingencies with lawsuits (R$ 9,216 million), basically due to the effect of class action's closing agreement (R$ 11,198 million), compared to R$ 1,215 million with individual agreements in 2016, ongoing in the United States;

•	Lower gains related to decommissioning of returned/abandoned areas of R$ 3,771 million;

•	Increase in the expense of pension and health plans due to the revision of the balance of the net actuarial obligation (R$ 1,160 million)

•	Lower Voluntary Separation Incentive Plan (PIDV) expenses (R$ 4,839 million), due to the partial reversion of PIDV provision, due to cancellation of enrollments by some employees in 2017 (R$ 757 million), compared to the PIDV expenses in 2016 (R$ 4,082 million);

•	Decreased reclassification of foreign exchange losses of R$ 3,577 million, resulting from the divestment of assets, mainly PESA, in 3Q‑2016 (R$ 3,627 million), from exchange depreciation previously recognized in the shareholder’s equity;

•	Higher foreign exchange and inflation indexation charges on the net debt (R$ 4,677 million), generated by:

✓

Foreign exchange losses of R$ 2.295 million driven by the impact of a 13.7% depreciation of the U.S. dollar against the Euro on the Company’s net debt in 2017, compared to the foreign exchange gains of R$ 464 million due to the 3.1% appreciation on the net debt in 2016 (R$ 2,759 million);

✓

Foreign exchange losses of R$ 123 million due to the 9.1% depreciation of the U.S. dollar against the the Pound Sterling over the average net debt in Pound Sterling in 2017, compared to the foreign exchange gains of R$ 1,422 million due to the 16.5% appreciation on the net debt in 2016 (R$ 1,545 million);

✓

✓

Finance charges arisen from the Company’s decision to adhere to the Brazilian federal settlement programs (R$ 2,693 million).

ACL – Ambiente de Contratação Livre (Free contracting market) in the electricity system.

ACR - Ambiente de Contratação Regulada (Regulated contracting market) in the electricity system.

Adjusted cash and cash equivalents - Sum of cash and cash equivalents, government bonds and time deposits from highly rated financial institutions abroad with maturities of more than 3 months from the date of acquisition, considering the expected realization of those financial investments in the short-term. This measure is not defined under the International Financial Reporting Standards – IFRS and should not be considered in isolation or as a substitute for cash and cash equivalents computed in accordance with IFRS. It may not be comparable to adjusted cash and cash equivalents of other companies, however management believes that it is an appropriate supplemental measure to assess our liquidity and supports leverage management.

Adjusted EBITDA – Net income plus net finance income (expense); income taxes; depreciation, depletion and amortization; results in equity-accounted investments; impairment, cumulative translation adjustment and gains/losses on disposal/write-offs of assets. Adjusted EBITDA is not a measure defined by IFRS and it is possible that it may not be comparable to similar measures reported by other companies, however management believes that it is an appropriate supplemental measure to assess our profitability. Adjusted EBITDA shall be considered in conjunction with other metrics for a better understanding on our performance.

Adjusted EBITDA Margin - Adjusted EBITDA divided by sales revenues.

ANP - Brazilian National Petroleum, Natural Gas and Biofuels Agency.

Basic and diluted earnings (losses) per share - calculated based on the weighted average number of shares.

Consolidated Structured Entities - Entities that have been designated so that voting or similar rights are not the determining factor that decides who controls the entity. Petrobras has no share of earnings in investments in certain structured entities that are consolidated in the financial statements, but the control is determined by the power it has over its relevant operating activities.

Feedstock processed (excluding NGL) - Daily volume of crude oil processed in the Company´s refineries in Brazil and is factored into the calculation of the Refining Plants Utilization Factor.

Feedstock processed – Brazil – Daily volume of crude oil and NGL processed.

Free cash flow - Net cash provided by operating activities less capital expenditures and investments in investees. Free cash flow is not defined under the International Financial Reporting Standards – IFRS and should not be considered in isolation or as a substitute for cash and cash equivalents calculated in accordance with IFRS.

Gross Margin – Gross profit over sales revenues.

Jet fuel – Aviation fuel.

Leverage – Ratio between the Net Debt and the sum of Net Debt and Shareholders’ Equity. Leverage is not a measure defined in the International Standards - IFRS and it is possible that it may not be comparable to similar measures reported by other companies,. however management believes that it is an appropriate supplemental measure to assess our liquidity.

Lifting Cost - Crude oil and natural gas lifting cost indicator, which considers expenditures occurred in the period.

LNG – Liquified natural gas.

LPG – Liquified crude oil gas.

LTM Adjusted EBITDA – sum of the last 12 months (Last Twelve Months) of Adjusted EBITDA. LTM Adjusted EBITDA is not a measure defined by IFRS and it is possible that it may not be comparable to similar measures reported by other companies, however management believes that it is an appropriate supplemental measure to assess our liquidity and supports leverage management.
