PETROBRAS ANNOUNCES RESULTS FOR THE FIRST QUARTER OF 2007
(Rio de Janeiro – May 11 2007) – PETRÓLEO BRASILEIRO S.A. – Petrobras announced today its consolidated results expressed in millions of Brazilian Reais, in accordance with generally accepted accounting practices in Brazil (BR GAAP).



Petrobras posted a consolidated net income of R$ 4.131 million in the first quarter of 2007. Consolidated net operating revenues totaled R$ 38.894 million, 8% higher than in the 1Q-2006 (R$ 35.886 million). At the close of the quarter, the Company’s market capitalization stood at R$ 215.666 million.


* Operating profit, before Financial Result

On a consolidated basis, Petrobras invested a total of R$ 8.300 million during the first quarter, up 40% from the same period a year ago. In line with the 2007-2011 Business Plan, most of the spending was used to expand future oil and natural gas production in Brazil (R$ 3.986 million) and abroad (R$1.737 million). Operating cash flow as measured by EBITDA amounted to R$ 10.993 million, ensuring sufficient resources to cover the Company’s investments.

Statement by the CEO, José Sergio Gabrielli de Azevedo

Dear shareholders,

The first quarter of 2007 was one period of consolidation and challenges, during which we faced, and continue to face, headwinds and adversity. Despite these problems, the Company has demonstrated its ability to adapt and to overcome challenges, as witnessed by our excellent quarterly operating result.

The first quarter is normally marked by a strong seasonal downturn in fuel consumption due to the lower number of calendar and business days in our main market, Brazil.

Additionally our technical team has been confronted with challenges in its upstream operations, as well as in the commercial and corporate areas. In our upstream activities, we are doing everything possible to minimize delays in the delivery of new production units, which unfortunately have slowed output growth in the short term. We are also facing difficulties related to the geology of the Golfinho reserve in Espírito Santo and high acidity levels in the output from the Albacora Leste field.

In the commercial area, we are concentrating our efforts on overcoming the problems in Bolivia and maintaining a secure supply of natural gas from that country.

Our corporate results during the quarter were affected by the appreciation of the Real and its impact on the net financial results. In addition we recognized some one time costs that should prove beneficial to the Company over the long term, such as the premium paid to investors as an incentive to exchange short term high coupon bonds for longer bonds with a lower coupon, and the increase in operating expenses generated by the financial incentive paid to Petros Plan participants (in exchange for amending the Plan).

Thus we began the year 2007 with great challenges, but also with a list of accomplishments, as we solidified our position in the markets where we operated, and completed strategic operations transactions designed to sustain the level of growth and accomplishments of recent years.

In this context, I draw particular attention to our joint acquisition of Grupo Ipiranga’s shares, which, in line with our strategic plan, will increase the value of our petrochemical holdings by contributing to the consolidation of the Southern Petrochemical Complex. It will also consolidate our position in the distribution sector, strengthening our hold in the North/Northeast and Midwest, as well as give us a share in the refining operations of Refinaria de Petróleo Ipiranga.

In exploration and production, despite the production difficulties mentioned above, the year began on a high note with the discovery of saturated light oil reserves with excellent productivity, located under a thick salt layer along the Espírito Santo coastline. This discovery has extended the productive horizon of the Caxaréu Basin, whose commercial potential was reported to the ANP in December 2006.

FPSO Cidade do Rio de Janeiro was installed and began producing during the quarter. Located offshore in the Espadarte Field in the Campos Basin, the platform has a daily production capacity of up to 100 thousand barrels of oil and 2.5 million cubic meters of natural gas. This new platform will help us to fulfill our key strategy of continuing to expand our production.

On the international front, we initiated production from two wells in the Cottonwood field, in the Gulf of Mexico. As a result, Cottonwood has become our biggest productive field in the United States, with daily output of 25 thousand BOE.

2


In the corporate area, we achieved our goal of 2/3’s adherence to the amended regulations of the PETROS Pension Plan. The implementation of these amendments will increase the transparency of the Company’s obligations to PETROS and their approval will also lead to the conclusion of agreements with union representatives aimed at settling and terminating all pending legal disputes related to the Petrobras System’s supplementary pension plan.

In the first quarter, we posted a consolidated net income of R$ 4.131 million. Net operating income amounted to R$ 38.894 million, 8% up year-on-year and the Company’s market capitalization stood at R$ 215.666 million at the end of the period.

In conclusion, I would like to re-emphasize our willingness, desire, and technical capacities, to overcome the challenges of today. We will do so in a sustainable manner, focusing on profitability and social and environmental responsibility. As a company, we will continue striving to make these concepts an integral part of our daily activities. We are fully confident in our ability to succeed during a period that is undoubtedly challenging, but which is also marked by unquestionable progress and new opportunities.

The reduction in net income for 1Q-2007 as compared to 1Q-2006 was primarily due to the decline in average prices for crude oil and petroleum products in Brazil and abroad, influenced by the fall in international oil prices. Below is a breakdown of the factors leading to the reduction in net income:

• A R$ 977 million reduction in gross profit:

• An increase in the following expenses:

• General and administrative expenses (R$ 455 million) expenses from salaries, bonuses and benefits in Brazil (R$ 109 million) and abroad (R$ 29 million) and greater expenditure on third-party services (R$ 115 million), especially IT and consulting support services; personnel training and development programs (R$ 42 million); new companies abroad (R$ 16 million); and leasing, rent and travel (R$ 25 million);

• Exploratory costs (R$ 345 million), particularly those incurred abroad (R$ 235 million);

• Costs with technological research and development (R$ 134 million), primarily to comply with ANP regulations (R$ 116 million);

• Other operating expenses (R$ 1.416 million), largely as a result of amendments to the Petros Plan regulations (R$ 1.040 million), advertising and marketing (R$ 85 million) and the Ibiritermo, Termobahia and Três Lagoas thermoelectric plants being idled(R$ 86 million).

• A negative impact of R$ 506 million on the net financial result, due to:

• Losses from monetary and exchange variations (R$ 1.006 million), given the higher credit balances denominated in U.S. dollars, partially offset by the lower appreciation of the Real in 2007 (R$ 570 million), and the non-recurring adjustment of the exchange variation in the 1Q-2006, totaling R$ 321 million;

• The premium paid to investors in the bond exchange, which occurred in February/2007 (R$ 112 million).

These negative impacts were partially offset by the following:

• Higher returns from domestic financial investments (R$ 269 million), resulting from the reduction in the dollar-denominated portion and the lower appreciation of the Real (4.10% in the 1Q-2007, versus 7.19% in the 1Q-2006);

• The reduction in financial expenses (R$ 149 million), due to lower debt and reduced margins;

The above effects were offset by the following factors:

• An increase in equity income (R$ 342 million), primarily due to reduced foreign exchange losses on the conversion of foreign subsidiaries’ shareholders equity, in turn due to the lower appreciation of the Real against the dollar in 1Q-2007 in comparison to 1Q-2006.

• An improved non-operating result (R$ 120 million) due to the sale of investments abroad and gains from changes in shareholding positions (R$ 35 million), plus the losses in 2006 from the write-off of receivables related to the loss of the P-36 platform (R$ 60 million);

6


Net income for 1Q-2007 (R$ 4.131 million) was 21% below the R$ 5.200 million reported in 4Q-2006.  The gross margin increased from the prior quarter, primarily due to the reduction in the government take, and import costs.  The increased gross margin, however, was more than offset by the non-recurring expense from the financial incentive paid to the pension plan participants, the impact of the exchange variation on the financial result, and the increase in the marginal tax rate relative to the fiscal benefit from interest on own capital declared in the 4Q-2006.  Below is a breakdown of the differences between 1Q-2007 and 4Q-2006:

• R$ 920 million increase in gross profit:

• A reduction in operating expenses (R$ 201 million) versus 4Q 2006 due to:

• Lower exploratory costs (R$ 163 million) when compared to the write-off from dry holes in the 4Q-2006 (R$ 125 million);

• Reduced selling expenses (R$ 135 million), most notably in the distribution and international segments;

• A decline in R&D expenses (R$ 97 million), especially from the adjustment to provisions for research and development expenses in compliance with ANP regulations (R$ 112 million) undertaken by CENPES (Petrobras Research Center);

• These decreases were offset by the increase in other operating expenses (R$ 416 million), largely as a result of the financial incentive paid to Petros Plan affiliates in exchange for accepting the amendments to the regulations (R$ 1.040 million), offset by reduced expenses on institutional relations and cultural projects (R$ 219 million).

• An increase of R$ 878 million versus 4Q 2006 for the net financial result, due to:

• Losses from monetary and exchange variations (R$ 581 million), given the higher appreciation of the Real (4.10% in the 1Q-2007, versus 1.66% in the 4Q-2006) and the monetary restatement of 2006 dividend payable;

• The premium paid to investors in the bond exchange that occurred in February/07 (R$ 112 million);

• Lower returns from financial investments (R$ 47 million), in Reais, due to the reduction in exchange gains and yields from Brazilian government bonds.

• Increase in income tax and social contribution (R$ 1.402 million), in contrast to the fiscal benefit from the interest on own capital payment declared in the 4Q-2006 (R$ 671 million).

Exploration and Production – thousand barrels/day

Domestic oil and NGL production increased by 3% versus 1Q-2006 due to the operational start-up of the platforms P-50 (Albacora Leste), in April 2006, FPSO-Capixaba (Golfinho), in May 2006, P-34 (Jubarte), in December 2006, and FPSO-Cidade do Rio de Janeiro (Espadarte), in January 2007.

Domestic oil and NGL production dipped by 1% in 1Q-2007 versus 4Q-2006, due to the scheduled maintenance stoppage in the P-37 platform (Marlim field) in January.

Consolidated international oil production dropped 30% when compared to 1Q-2006 due to loss participation in Venezuela’s operations as a result of the contractual shift from an operating agreement to a joint venture agreement, in which the Venezuelan government assumed a controlling interest through PDVSA. Consolidated gas production declined by 4% year-on-year, due to the resumption of normal production in the United States, which was adversely affected in 2006 by hurricanes Rita and Katrina.

Consolidated international oil production fell by 3% as compared to the 4Q-2006 due to the interruption of operations in Ecuador caused by popular unrest. Consolidated gas production increase 6% quarter-over-quarter as a result of increased demand for Bolivian gas in Argentina and the operational start-up of the Cottonwood field in the United States.

Refining, Transportation and Supply – thousand barrels/day

The volume of processed crude in domestic refineries during the quarter (primary processing) dipped 1% versus the same period one year earlier, due to scheduled maintenance stoppages in the Replan and Reman refineries and the cleaning of furnaces.

In comparison with 4Q-2006, which had a higher number of maintenance stoppages, domestic processed crude increased by 4%.

Processed crude in the overseas refineries (primary processing) jumped by 100% versus 1Q-2006, due to the inclusion of the Pasadena Refinery (USA) as of October/06 and the increase in Argentine refining capacity.

In relation to the previous quarter, total processed throughput in the overseas refineries dropped by 1%, due to the scheduled maintenance stoppages in Bolivia and the United States, offset by the return to regular operations in the Argentina refinery, as a result of stoppage to increase the implementation of the installed capacity during 4Q-2006.

Costs

Lifting Cost (US$/barrel)

The unit lifting cost in Brazil, excluding government take, increased by 14% in relation to 1Q-2006. Excluding the impact of the 4% appreciation of the Real on lifting costs denominated in Reais, unit lifting costs climbed 11%. The upturn was due to increased expenditure on interventions in wells, preventive and corrective maintenance and the chartering costs of drilling and associated support ships; higher personnel expenses due to wage hikes and the increase in the workforce; and the higher unitary costs of new platforms FPSO-Capixaba (Golfinho), P-34 (Jubarte) and FPSO-Cidade do Rio de Janeiro (Espadarte), which are expected to trend down as they utilize their full capacity.

In comparison with 4Q-2006, the unit domestic lifting cost, excluding government take, decreased by 1% because of less use of repair materials for well intervention and equipment replacement, partially offset by decrease in production due to programmed stoppages in the period.

Including government take, lifting costs fell by 6% over the 1Q-2006 due to the decline in the reference price used to assess government take (tied to the international price), and the lower tax bracket used to calculate Special Participation, particularly in the Marlim and Marlim Sul fields, caused by reduced production related to natural declines, as well as January’s scheduled maintenance stoppage in the P-37 platform.


Including government take, the domestic unit lifting cost dropped by 8% over 4Q-2006, once again due to the decline in the domestic oil reference price (in line with international prices), as well as reduced output from the Marlim field, as a result of the scheduled maintenance stoppage in the P-37 platform, which reduced the tax rate used to assess Special Participation.

The international unit lifting cost increased by 31% in comparison with 1Q-2006, due to increased expenditure in the United States following the return to normal operations which had been affected by hurricanes Rita e Katrina in 2006; the operational start-up of the Cottonwood field in February/07; and higher expenditure in Angola on restructuring, maintenance of the facilities and recovery of mature wells.

12

 


The international unit lifting cost decreased by 11% in 1Q-2007 versus the prior three months, due to reduced expenditure on well repairs in Argentina, as well as on restructuring, maintenance of the facilities and the recovery wells.

Refining Cost (US$/Barrel)


Domestic unit refining costs moved up 34% as compared to the prior year’s first quarter, due to increased operating expenses reflecting the investments to adapt the refineries for heavy oil processing as well as improve the fuel quality to meet more stringent environmental requirements. Additionally, cost increased as a result of the larger number of scheduled maintenance stoppages. Excluding the impact of the 4% appreciation of the Real on Real-denominated refining costs, these costs climbed by 29%.

In relation to 4Q-2006, the unit refining cost fell by 6%, due to reduced personnel expenses (salaries, bonuses and benefits) caused by the recognition of retroactive wage increase granted by the collective bargaining agreement in the prior quarter.

Average unit international refining costs climbed 54% over the first quarter of 2006, due to the inclusion of the Pasadena Refinery (USA). Excluding this impact, refining costs would have fallen by 8%, due to the 9% increase in production.


Average unit international refining costs increased by 16% quarter-over-quarter, due to the maintenance stoppage and the higher cost of materials in the United States.

13


Corporate Overhead – Parent Company (US$ million)

In comparison with 1Q-2006, corporate overhead climbed by 29% in 1Q-2007, reflecting the growth and increased complexity of the Company’s operations. Excluding the impact of the 4% appreciation of the Real (given that all such costs are denominated in Reais), the corporate overhead increased 25% year-on-year due to higher expenses from specialized technical services, sponsorships, marketing and advertising, and increases in salaries, bonuses and benefits as a result of the collective bargaining agreements and larger workforce.

Corporate overhead fell by 13% over the previous quarter, primarily due to higher expenses from cultural sponsorships in 4Q-2006, including those benefiting from the Rouanet Law, and donations to the FIA (Childhood and Adolescence Fund).

Sales Volume – Thousand Barrels/day

Domestic sales volume in 1Q-2007 was up 1,5% versus 1Q-2006, led by fuel oil, LPG and aviation fuel, reflecting higher demand from the manufacturing industry and thermoelectric power plants, population growth, increased earnings among the less favored income groups, the expansion of tourism and GDP growth.

Gasoline volume recorded an increase, triggered by the reduction in the anhydrous alcohol ratio in type “C” gasoline and the increase in consumer income. Diesel sales declined, due to the start-up of thermoelectric plants powered by fuel oil, as well as exceptionally heavy rainfall which reduced transport levels, in turn reducing the level of operations in agricultural, mining and construction machinery.

Export volumes rose by 17%, as a result of increased production and the reduced share of domestic oil production in total processed throughput.

International sales volume climbed by 53% due to the inclusion of the Pasadena Refinery’s operations in October/06, the increase in US output and commercial operations abroad, partially offset by the deconsolidation of operations in Venezuela.

Decrease in the oil products sales when compared with 4Q06, mainly diesel, LPG and gasoline due to the seasonality effect and the distribution companies’ high level inventories.

Especially about diesel the usual decrease because of seasonality was exceptionally caused by reduced activity level in industry and agriculture operations given the remarkably heavy rainfall period and substitution from diesel to fuel oil in the Manaus thermo-plants operations.

The natural gas sales volumes decline because of lower sales for thermoelectric power stations and, in lower level, of gas for other utilities, due to the seasonality.

RESULTS BY BUSINESS AREA

Petrobras is a company that operates in an integrated manner, with the greater part of oil and gas production in the Exploration and Production area being sold or transferred to other Company areas.

The main criteria used to report results per business area are as follows:

a) Net operating revenues: revenues from sales to external clients, plus intra-Company sales and transfers, using internal transfer prices established between the various areas as a benchmark, with assessment methodologies based on market parameters;

b) Operating income: net operating revenues, plus the cost of goods and services sold, which are reported by business area, taking into account the internal transfer price and other operating costs for each area, plus the operating expenses effectively incurred by each area;

c) The entire financial result is allocated to the corporate group;

d) Assets: refers to the assets as identified by each area. Equity accounts of a financial nature are allocated to the corporate group.


E&P: Net income from Exploration and Production totaled R$ 5,096 million in 1Q-2007, down 25% from the first three months of 2006 (R$ 6,774 million), due to the following factors:

      • A R$ 1,904 million reduction in gross profit, due to the decline in average domestic oil prices, partially offset by the 3% upturn in oil and NGL output, lower production costs and higher average transfer prices for natural gas;

      • Expenses of R$ 220 million, comprised of financial incentives to pension plan participants in exchange for accepting amendments to the plan’s regulations.

The spread between the average domestic oil price and the average Brent price widened from US$ 8.07/bbl in 1Q-2006 to US$ 9.96/bbl in 1Q-2007.

In comparison with the previous quarter, net income increased 10% during 1Q-2007 due to lower production costs and higher average transfer prices for natural gas, partially offset by the reduction in oil and NGL output triggered by the scheduled maintenance stoppage in P-37 and the lower average sale/transfer prices for domestic oil.

The spread between the average domestic oil sale/transfer price and the average Brent price narrowed from US$ 10.98/bbl in 4Q-2006 to US$ 9.96/bbl in 1Q-2007.

SUPPLY: The Supply segment recorded a net income of R$ 2,144 million in 1Q-2007, up 7% from the R$ 2,000 million registered during the same period of 2006, reflecting the reduction in the average price of oil acquired, lower prices for oil product imports associated with the 4% appreciation of the Real, and the lower cost of heavy oils, partially offset by:

      • A 2% decline in the average domestic sale price of basic oil products;

      • A 9% reduction in oil product export volumes;

      • The sale of inventories in 1Q-2006 that had been acquired at a lower cost at the end of 2005.

The increase in other operating expenses was primarily due to expenses of R$ 129 million from the financial incentive to pension plan participants in exchange for their acceptance of the amendments to the regulations.

16


In comparison with 4Q-2006, net income increased by 47% during the quarter due to the reduction in the oil acquisition/transfer cost, and the sale, in 4Q-2006, of inventories acquired at a higher cost, partially offset by the 3% decline in domestic oil product sales volume and the narrower spread between heavy and light oils.

 

GAS AND ENERGY: Gas and Energy recorded a loss of R$ 314 million (versus a loss of R$ 78 million in 1Q-2006), generated by the increase in the average domestic transfer cost for natural gas, partially offset by the improvement in the energy sales margin due to the lower energy acquisition cost, in turn caused by the rise in the reservoir levels of Brazil’s hydro plants.

The comparison with the previous quarter was less marked (net loss of R$ 314 million versus a loss of R$ 307 million in 4Q-2006). The difference was the result of:

• The increase in the average transfer cost of domestic natural gas;

• The 10% reduction in natural gas sales volume.

These effects were partially offset by the increase in energy sales volume and the wider sales margin, resulting from lower acquisition costs of electricity.

DISTRIBUTION: The Distribution segment posted a first-quarter net income of R$ 189 million, 16% more than the R$ 163 million declared in 1Q-2006, pushed by the 11% upturn in sales volume.

According to the new criterion, which revised market volume for ethanol, the market share of the fuel distribution business was 33.9% against 31.6% in 1Q06 (equivalent to 32.7% based on the previous criterion).

Net income increased by 45% over 4Q-2006 due to the wider sales margin. This effect was partially offset by a 4% drop in sales volume, reflecting the smaller number of days in comparison with the final three months of 2006, and the decline in the segment’s share of the fuel distribution market from 35.1%, in the 4Q-2006, to 33.9% .

The reduction in selling expenses also contributed to the 1Q-2007 improvement.

INTERNATIONAL: The International segment generated a net loss during the first-quarter 2007 of R$ 259 million, versus net income of R$ 236 million in 1Q-2006.

This reversal was primarily due to:

• A R$ 273 million decrease in gross profit caused by:
     i) The reduced income from Venezuelan operations;
     ii) the increase in government take in Bolivia;
     iii) the decline in international oil prices;
     iv) the impact of the 6% appreciation of the Real against the US dollar on the financial statement currency conversion process.

• A R$ 235 million increase in exploration and drilling expenses from the acquisition of seismic data in Turkey, Angola and United States.

The first-quarter loss of R$ 259 million was very close to the R$ 247 million loss reported in the 4Q-2006.

17


CORPORATE: Corporate activities generated a loss of R$ 2,616 million in 1Q-2007, versus a loss of R$ 1,862 million in 1Q-2006, as a result of:

• Expenses of R$ 632 million as financial incentive to pension plan participants in exchange for their acceptance of the amended plan;

• The R$ 506 million increase in net financial expenses, as detailed on page 6;

• The R$ 190 million increase in G&A expenses resulting from higher third-party services and personnel expenses, the latter due to the expansion of the workforce in 2006 and the collective bargaining agreement.

These effects were partially offset by the reduction in foreign exchange losses from the conversion of equity investments abroad due to the lower appreciation of the Real in relation to 1Q-2006;

The variation between 1Q2007 and 4Q-2006 quarter was even larger (loss of R$ 2,616 million, versus a loss of R$ 798 million in 4Q-2006) mainly due to:

• The R$ 878 million increase in net financial expenses (see page 8);

• Expenses of R$ 632 million from the financial incentive to pension plan participants in exchange for their acceptance of the amended plan;

• The higher tax burden caused by the non-recurrence of the fiscal benefit from provisioning of interest on equity, which totaled R$ 671 million in 4Q-2006.

These effects were partially offset by reduced expenses from institutional relations and cultural projects (R$ 161 million).

Government participation in Brazil declined by 16% in relation to 1Q-2006, due to the 12% decrease in the reference price for local oil, which averaged R$ 98.40 (US$ 46.72), versus R$ 111.80 (US$ 50.93) in 1Q-2006, reflecting the lower average Brent price on the international market, as well as the lower tax rate bracket use to calculate Special Participation, especially in relation to the Marlim and Marlim Sul fields due to the natural decline in production, as well as the scheduled maintenance stoppage in the P-37 (Marlim) platform in January 2007.

4. Reconciliation of Consolidated Shareholders’ Equity and Net Income

    R$ million 
         
    Shareholders' Equity    Result 
. According to PETROBRAS information as of March 31, 2007    103.718    4.336 
. Profit in the sales of products in affiliated inventories    (321)    (321) 
. Reversal of profits on inventory in previous years      438 
. Capitalized interest    (780)    (47) 
. Absorption of negative net worth in affiliated companies *    (267)    (187) 
. Other eliminations    (603)    (88) 
     
. According to consolidated information as of March 31, 2007    101.747    4.131 
     

* Pursuant to CVM Instruction 247/96, losses considered temporary on investments evaluated by the equity method, where the investee shows no signs of stoppage or the need for financial support from the investor, must be limited to the amount of the controlling company’s investment. Thus losses generated by unfunded liabilities (negative shareholders’ equity) of the controlled companies did not affect the results or shareholders’ equity of Petrobras on March 31, 2007, generating a reconciling item between the Financial Statements of Petrobras and the Consolidated Financial Statements.
