Discussion of Consolidated Results of Operations

The following table sets out the Company’s results of operations for the three and six-month periods ended June 30, 2015 and 2014:

(in millions of pesos)

ANALYSIS FOR THE THREE-MONTH PERIODS ENDED JUNE 30, 2015 AND 2014:

Net income: Net income attributable to the Company’s shareholders totaled 524 in the period under review and 354 in 2014 quarter.

Sales: Sales rose 299 to 5,237 from 4,938 in 2014 quarter, mainly due to increases in the Refining and Distribution, Petrochemical and Gas and Energy business segments of 187, 152 and 87, respectively, with reduced eliminations attributable to intercompany sales amounting to 29. These positive effects were partially offset by a 156 drop in sales in the Oil and Gas Exploration and Production business segment, mainly due to the sale of assets in the Austral basin in the first quarter of 2015.

Gross profit: Gross profit increased 62 to 1,656 in the quarter under review from 1,594 in 2014 quarter, mainly due to improvements in the Refining and Distribution and Petrochemicals business segments, offset by declines in the Oil and Gas Exploration and Production and Gas and Energy business segments. It should be noted that results from intercompany transactions recorded a positive variation of 74, mainly due to a reduction in the refinery’s own crude oil production levels.

Administrative and selling expenses: Administrative and selling expenses totaled 659 in the quarter under review and 589 in 2014 quarter. In 2015 quarter higher tax charges and transportation expenses are attributable to increased sales in the period under review.

Exploration expenses: Exploration expenses are attributable to onshore operations in Argentina and totaled 19 in 2015 quarter and 11 in 2014 quarter.

Other operating income (expenses), net: Other operating expenses totaled losses of 125 and 108 in 2015 and 2014 quarters, respectively.

Share of net profit of equity-accounted investees: Share of net profit of equity-accounted investees improved 192, accounting for a gain of 24 in 2015 quarter compared to a loss of 168 in 2014, which period was adversely affected by the recognition of a loss of 228 attributable to equity interest in OCP.

Operating income: Operating income rose 159 to 877 in the period under review from 718 in 2014 quarter, basically due to the above mentioned improvement in share of net profit of equity-accounted investees, partially offset by higher administrative and selling expenses.

Financial results: Financial results accounted for gains of 11 and 18 in 2015 and 2014 quarters, respectively. Both periods were favorably impacted by the effect of the depreciation of the Argentine peso against the US dollar on the Company’s net monetary asset position.

Income tax: Income tax charge totaled 326 and 344 in 2015 and 2014 quarters, respectively. Higher income tax charges for 2014 quarter are mainly attributable to investments in OCP, with losses not generating the corresponding tax shield. This accounted for an increase in the income tax effective rate in 2014.

Analysis of Gross Profit

Oil and Gas Exploration and Production

Gross profit for this business segment is broken down as follows:

(in millions of pesos)

Sales: In 2015 quarter, sales decreased 156 to 2,414 from 2,570 in 2014, mainly due to lower sales volumes of oil and gas as a consequence of the sale of assets in the Austral basin in the first quarter of 2015, partially offset by an improvement in gas sales prices.

Oil sales decreased 235 million to 1,802 million in 2015 quarter from 2,037 in 2014 quarter, mainly due to the decline in sales volumes resulting from the sale of the Austral basin and, to a lesser extent, the natural decline of mature fields.

Gas sales rose 85 to 590 in 2015 quarter from 505 in 2014 quarter, mainly as a consequence of an improvement in average sales prices for the residential segment, partially offset by a decline in sales volumes, which totaled 198 MMcf/d in 2015 quarter and 252 MMcf/d in 2014 quarter, mainly derived from the sale of the Austral basin. In 2015 quarter, production from the Neuquén basin increased due to the start of production of non-conventional gas wells which allowed to offset the natural decline of mature fields.

Gross profit: Gross profit for this business segment totaled 830 in 2015 quarter and 904 in 2014 quarter, with similar margins on sales in both periods, nearing 35%.

Refining and Distribution

Gross profit for this business segment is broken down as follows:

(in millions of pesos)

Sales: Sales for this business segment rose 187 to 2,942 in 2015 quarter from 2,755 in 2014 quarter, as a result of the combined effect of increased sales volumes and improved refined product sales prices, partially offset by lower crude oil sales volumes in the quarter under review.

Refined product sales volumes totaled 496.2 thousand cubic meters in 2015 quarter and 467.1 thousand cubic meters in 2014 quarter, in line with an increased demand in the period under review.

Gross profit: Gross profit for this business segment totaled 401 in 2015 quarter and 357 in 2014 quarter, with similar margins on sales of 13.6% and 13% in both periods.

Petrochemicals

Gross profit for this business segment is broken down as follows:

(in millions of pesos)

Sales: In 2015 quarter, sales rose 152 to 1,224 from 1,072 in 2014 quarter, mainly due to increased sales from the catalytic reformer plant operations and, to a lesser extent, styrenics.

Sales revenues resulting from the catalytic reformer plant operations rose 138 to 495 from 357, as a consequence of the combined effect of increased sales volumes and higher prices stated in pesos. The rise in volumes is attributable to increased virgin naphtha volumes processed.

Styrenic product sales revenues rose 14 to 729 from 715, as a consequence of increased sales volumes of polystyrene attributable to a higher domestic demand, partially offset by the drop in average sales prices for styrene and synthetic rubber, in line with the drop in international prices.  

Gross profit: Gross profit totaled 227 in 2015 quarter and 199 in 2014 quarter, and margins on sales were similar in both quarters, nearing 18.5%.

Gas and Energy:

Gross profit for this business segment is broken down as follows:

(in millions of pesos)

- Electricity Generation

Sales: In 2015 quarter, sales for electricity generation increased 8 to 396 from 388 in 2014, mainly due to an improvement in average sales prices, partially offset by lower sales volumes, which dropped to 1,559 Gwh from 1,722 Gwh, as a consequence of the scheduled shutdown for maintenance works at Genelba Power Plant in the period under review.

Gross profit: Gross profit totaled 157 in 2015 quarter and 166 in 2014 quarter, with margins on sales of 39.6% and 42.8% in 2015 and 2014 quarters, respectively.

 

Marketing and Transportation of Gas

Sales: In 2015 quarter, natural gas sales revenues rose 88 to 619 from 531, mainly due to an improvement in average sales prices, partially offset by a decline in sales volumes, which totaled 207 million cubic feet in 2015. The rise in average sales prices is mainly attributable to increased volumes of non-conventional gas sold at Gas Plus price and improved prices for the residential and CNG segment.

Gross profit: Gross profit was close to zero, reflecting a loss of 4 in both periods.

ANALYSIS FOR THE SIX–MONTH PERIODS ENDED JUNE 30, 2015 AND 2014:

Net income: Net income attributable to the Company’s shareholders totaled 1,346 in the period under review and 1,052 in 2014 six-month period.

Sales: Sales rose 943 to 10,511 from 9,568 in 2014 six-month period, mainly due to improved average prices which accounted for increases in sales revenues of 744, 244, 151 and 114 in the Refining and Distribution, Gas and Energy, Oil and Gas Exploration and Production and Petrochemicals business segments, respectively. These effects were partially offset by increased  eliminations attributable to intercompany sales amounting to 310 and, to a lesser extent, the sale of assets in the Austral basin in the first quarter of 2015.

Gross profit: Gross profit increased 62 to 3,208 in the period under review from 3,146 in the same period of 2014, with improvements in gross profit for the Refining and Distribution and Gas and Energy business segments, and declines in the Oil and Gas Exploration and Production and Petrochemicals business segments. In addition, the decline in inventory levels at the refinery resulted in a positive variation attributable to intercompany transactions.

Administrative and selling expenses: Administrative and selling expenses totaled 1,353 in the period under review and 1,101 in 2014 six-month period. In 2015 six-month period higher tax charges and transportation expenses derived from increased sales in the period under review.

Exploration expenses: Exploration expenses are attributable to onshore operations in Argentina and totaled 31 in 2015 six-month period and 25 in the same period of previous year.

Other operating income (expense), net:  Other operating income (expense) improved 545, accounting for a gain of 460 in 2015 six-month period, compared to a loss of 86 in the same period of previous year. This improvement is mainly attributable to the sale of assets in the Austral basin in the period under review which resulted in a gain of 674, and to the gain of 181 in the same period of previous year derived from the sale of interest in Puesto Hernández Joint Venture (UTE).  

Share of net profit of equity-accounted investees: Share of net profit of equity-accounted investees improved 185, accounting for a gain of 10 in 2015 six-month period compared to a loss of 175 in the same period of previous year. This improvement is primarily due to the recognition of a loss of 228 in 2014 six-month period attributable to equity interest in OCP.

Operating income: Operating income rose 535 to 2,294 in 2015 six-month period from 1,759 in the same period of previous year, primarily due to the above mentioned improvement in Other operating income (expense), share of net profit of equity-accounted investees and gross profit, partially offset by higher administrative and selling expenses.

Financial results: Financial results accounted for a loss of 15 in 2015 six-month period compared to a gain of 202 in the same period of previous year. Improved results in 2014 six-month period are primarily attributable to the positive effects of higher depreciation of the Argentine peso against the US dollar (25% and 6% in 2014 and 2015, respectively) on the net monetary asset position in foreign currency.

Income tax: Income tax charge totaled 856 and 888 in 2015 and 2014 six-month periods, respectively. Higher income tax charges for 2014 six-month period are mainly attributable to investment in OCP, with losses not generating the corresponding tax shield. This accounted for an increase in the income tax effective rate in the same period of previous year.

Summarized Balance Sheet and Income Statement Structure

Statistical Data

Outlook

Our main goal for 2015 is to consolidate Petrobras Argentina as a robust, flexible, efficient and profitable company that will allow us to overcome the challenges posed by the context. In this respect, the Company plans to enhance development of resources in order to achieve in the short-term a balanced replacement of production from mature reservoirs and grow sustainably.

Concerning the Oil and Gas Exploration and Production business segment, the Company needs to ensure certainty of its operations to move forward with its investment and production plan to generate over time the funds required to finance the development of the Company’s non-conventional resources. In this respect, the Company expects to formalize the agreement for the extension of its exploitation concessions reached with the Province of La Pampa as it did with the Province of Río Negro.

As regards natural gas, the Company participates in the Natural Gas Injection Incentive Program for Companies with reduced Injection (Gas Plan II), which program will contribute to monetize reserves.

Concerning Refining and Distribution activities, in 2015 the Company plans to continue with efficiency and high performance programs at the refinery and maintain the improvements obtained in quality of service to our clients and in logistics cost reduction.

As regards the Petrochemicals business segment, in 2015 we seek to secure availability of basic raw materials at prices in line with those for our products and guarantee plant operations at a cost level required to reach a standard of competitiveness.

In the Gas and Energy business segment, we plan to continue with the high operating performance for which our assets stand out in the power generation sector.

The Company’s results of operations and financial position are sensitive to changes in the exchange rate between the Argentine Peso and certain foreign currencies.

The Company is mainly exposed to changes in the peso exchange rate against the U.S. dollar. Petrobras Argentina’s exposure to currencies other than the US dollar is not significant.

The Company has a net asset position in foreign currency because of the fact that a significant portion of its debt is designated as hedge of investment in foreign currency, so the exchange differences generated by this debt are recognized in “Other comprehensive income”.

The variation in the exchange rate in the quarter ended June 30, 2015 generated a gain of 37 imputed to "Financial Results" (Note 9) and a deferred gain of 1 imputed OCI (Note 23).

REPORT ON REVIEW OF CONDENSED INTERIM CONSOLIDATED FINANCIAL INFORMATION

To the Shareholders, President and Directors of Petrobras Argentina S.A.

Introduction

We have reviewed the accompanying condensed interim consolidated financial statements of Petrobras Argentina S.A. (“PESA" or "the Company") and its subsidiaries, including the consolidated statement of financial position as of June 30, 2015, the consolidated statements of income, the comprehensive income for the three and six-month period then ended, the consolidated statements of changes in shareholders' equity and cash flows for the six-month period then ended and the selected explanatory notes. The balances and other information for the year 2014 and for its interim periods are an integral part of these financial statements and, therefore, they should be considered in relation to those statements.

Board Responsibility

The Company's Board of Directors is responsible for the preparation and presentation of these condensed interim consolidated financial statements in accordance with International Financial Reporting Standards (IFRS), adopted by the Argentine Federation of Professional Councils in Economic Sciences (FACPCE, for its acronym in Spanish) as professional accounting standards and added by the National Securities Commission (CNV, for its acronym in Spanish) to its regulations, as approved by the International Accounting Standard Board (IASB). Therefore, they are responsible for the preparation and presentation of the condensed interim consolidated financial statements mentioned in the first paragraph, in accordance with International Accounting Standard No. 34 "Interim Financial Reporting" (IAS 34).

Scope of review

Our review was limited to the application of the procedures established in the International Standard on Review Engagements 2410, 'Review of interim financial information performed by the independent auditor of the entity', which was adopted as review standard by Technical Pronouncement No. 33 of the FACPCE in Argentina, as approved by the International Auditing and Assurance Standard Board (IAASB). A review of interim financial information consists in making inquiries to the company personnel responsible for the preparation of the information included in the condensed interim consolidated financial statements and in the preparation of analytical and other review procedures. This review is substantially less in scope than an audit conducted in accordance with International Auditing Standards (IAS), and consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion on the consolidated statement of financial position, the consolidated statements of comprehensive income and cash flows of the Company.

Fundamentals of our conclusion with exceptions

We were unable to review the financial information as of June 30, 2015 and 2014 supporting the value recorded for the direct and indirect equity investments in mixed companies in Venezuela, the recorded amount of which totals $ 2,827 million.

Conclusion with exceptions

Based on our review, except for the possible effects of the situation mentioned in paragraph “Fundamentals of our conclusion with exceptions”, no issues have come to our attention that make us believe the condensed interim consolidated financial statements mentioned in the first paragraph have not been prepared, in all material respects, in accordance with IAS 34.
