CHAIRMAN'S STATEMENT

Overview

Our financial results incorporating the results of Andes together with its subsidiaries for the year ended 31 December 2012 are set out below.

In 2012 the Group achieved the successful demerger of the utility generating and distribution operations, which has resulted in certain of the comparative figures being re-presented. The results of the utility operations up to the date of the demerger have now been classified as discontinued operations in the comparative income statements and cash flow statement. The balance sheet information for the utility operations at 31 December 2011 is, however, still included in the respective line categories in the balance sheet.

The Group recorded a loss before tax from continuing operations of US$4.4 million for the year compared to a loss before tax and exceptional items of US$2.6 million in 2011. The discontinued utility operations recorded a loss attributable to equity holders of the parent of US$22.9 million compared to a profit of US$3.2 million recorded in 2011. The main reason for this loss is the recognition of a recycled foreign exchange loss of US$26.5 million on the demerger.

During the year, Andes completed the acquisition of Andes Hidrocarburos Investments S.A. ("AHI"). AHI owns; a 100% conventional and unconventional interest in the Repatriación block in the Chaco-Parana basin in Paraguay; a 100% conventional and unconventional interest in the Los Buitres, Mina Baku and La Brea blocks in the Neuquen basin; a 100% interest in the Agrio formation and a 40% carried interest in the other formations in a 296 km2 area of the El Manzano block in the Neuquen basin.

Just before the year end the Board announced the award of eight blocks in Colombia following the Group's participation in the Agencia Nacional de Hidrocarburos ("ANH") 2012 Bidding Process.

Outlook

The successful demerger of the utility operations has resulted in a strong and focused oil and gas Group that is well positioned to develop and enhance the enormous potential of its portfolio of assets with conventional and unconventional prospects.

Following the year end we completed successfully the acquisitions of Kilwer S.A. and Ketsal S.A.. The combination of the Kilwer, Ketsal and Andes assets is strategically very valuable, adding new exploration and production fields and increasing and strengthening our position in a number of licences.

I would also like to welcome Alejandro Jotayan, Rudolph Berends, German Ranftl, Alan Stark, David Jackson, Javier Alvarez and Carolina Landi to the board and at the same time to thank Leandro Carbone, Neil Bleasdale, Luis Alvarez Poli and Marcelo Comba for their valuable contribution during their tenure.

We are confident that we now have the assets and management in place to allow us to increase production, add a further uplift to our resources and reserves and continue with our exploration strategy with a view to adding new discoveries in the short to medium term.

CHIEF EXECUTIVE'S REVIEW

Introduction

The highlights for 2012 are the:

·; successful completion of the demerger of the Group's utility assets

·; award of 8 licence blocks in Colombia in Open Round Colombia 2012 tender

·; discovery of oil and gas in well YPF.NQ.MMO.x-1 in the Vaca Muerta formation in the Mata Mora block. Net prospective resource of 62.75 mmboe attributed to Andes's participation 

·; discovery of oil and gas in well YPF.NQ.Corr.x-1 in the Vaca Muerta formation in the Corralera block. Net prospective resource of 108.41 mmboe attributed to Andes's participation

·; acquisition of AHI with conventional and unconventional interests in Argentina and Paraguay

Oil and Gas Interests

Andes Energia has made substantial progress in expanding its oil and gas portfolio.

As part of our stated objective, we continued to grow and consolidate our oil and gas interests with the aim of creating a unique oil and gas portfolio in Latin America whilst at the same time de-risking the assets.

During 2012 the Group, through the acquisition of AHI, acquired; a 100% conventional and unconventional interest in the Repatriación block in the Chaco-Parana basin in Paraguay; a 100% conventional and unconventional interest in the Los Buitres, Mina Baku and La Brea blocks in the Neuquen basin located in the Province of Mendoza, Argentina; and a 100% interest in the Agrio formation and a 40% carried interest in the other formations in a 296 km2area of the El Manzano block in the Neuquen basin located in the Province of Mendoza, Argentina.

The Group, in consortium (the "Consortium") with Integra Oil and Gas SAS ("Integra"), was also successful in Colombia´s Agencia Nacional de Hidrocarburos 2012 Bidding Process and was awarded 8 blocks. The blocks awarded were: Llanos 2, Llanos 3, Llanos 12, Llanos 28, Llanos 49, Llanos 51, Llanos 79 and VMM 8. Andes has a 70% interest in the Consortium. The Consortium was the most successful bidder for Class 1 blocks in the bidding process and the second most successful bidder overall, after Ecopetrol and its affiliates. The terms of the bids by the Consortium include the lowest royalty, in the range 2-15%, amongst the other successful bidders for Class 1 blocks. Seven of the eight blocks awarded are located in the Llanos basin, the most prolific oil basin in Colombia. These blocks are surrounded by fields that are currently in production. The eighth block, VMM8 is located in the "Valle Medio del Magdalena", which has high potential for conventional and unconventional resources. The total area of the blocks awarded to Andes covers 470,000 acres. Preliminary estimates by the Company indicate that there could be total recoverable resources of over 100 million barrels of oil in the seven blocks. The Consortium has already signed a finance agreement with Integra, under which Integra will fund the exploration program on blocks LLA 3, LLA 12, LLA 51 and LLA 79.

Andes has significantly increased and improved its portfolio through the year, which now includes;

·; 44 licences

·; 7 million of net acres

·; 19 million boe of 2P net reserves

·; 600 million boe of net contingent and prospective resources (management estimate)

(includes interests acquired after the year end)

Vega Grande, La Paloma and Cerro Alquitrán

During the year, 3D seismic re-interpretation was completed in La Paloma and Cerro Alquitrán and four environmental permits to drill were presented.

Corralera and Mata Mora Blocks

The Mata Mora block covers 58,317 acres (236 km²) and is located in the eastern region of Argentina's Neuquén basin.

Well MMo.x-1 was drilled, cased and cemented to a total depth of 3,151 metres and found the target Vaca Muerta shale formation. The top of the Vaca Muerta formation was reached at a depth of 2,990 metres with a total of 136 metres penetrated. A hydraulic fracture stimulation of the Vaca Muerta was performed targeting the following horizons 3,054.3 - 3,055.0 mbgl, 3,065.3 - 3,066.0 mbgl, 3,075.3 - 3,076.0 mbgl, 3,085.0 - 3,085.7 mbgl and 3,100.3 - 3,101.0 mbgl.

The well produced on average 10.3 m³/d of oil and 1,434 m³/d of gas during the production testing period through a 4 mm choke (10/64 inch) at flow pressures of 13.8 kg/cm² and above. Drilling operations were conducted by YPF S.A. ("YPF"), Andes's partner and operator in the Mata Mora block. YPF is Argentina's largest oil and gas development company.

The Corralera block covers 83,027 acres (336 km2) and is located in the North West region of the Neuquén Basin in West Central Argentina. The Corralera block lies west of Chihuido de la Sierra Negra (the largest producing oil field in the country with cumulative production of 555 mmbbls) and east of Filo Morado (cumulative production of 65 mmboe).

Well Corr.x-1 was drilled and cased to a total depth of 2,405 metres and found the target Vaca Muerta shale formation, which displays highly prospective properties that exceed the prognosis made prior to drilling. The top of the Vaca Muerta formation was reached at a depth of 2,058 metres with a total of 346 metres penetrated. The Vaca Muerta shale formation is a thick rich source rock that offers potential for unconventional shale gas and shale oil.

The Vaca Muerta formation is one of two principal source rocks in the Neuquén basin in Argentina. The formation is late Jurassic, early Cretaceous in age, covers an area of approximately 7.41 million acres (30,000 km²), varies in depth between 5,500 to 14,000 feet and in places is up to 1,400 feet thick. In published reports, the U.S. Energy Information Administration has estimated a risked, recoverable resource of 240 trillion cubic feet ("TCF") of shale gas from the Vaca Muerta formation in the Neuquén basin.

Confluencia, San Bernardo, Pampa Salamanca Norte, Buen Pasto, Sierra Cuadrada, Rio Senguerr and Laguna El Loro Blocks

In 2011 we acquired our previous joint venture partner's interest in six blocks in the province of Chubut and one block in the province of Rio Negro in order to stimulate activity on these blocks. In May 2011 we successfully signed a farm-in agreement with YPF for the six blocks in Chubut to explore the vast area of approximately 25,500 km2.

As a result of this farm-in agreement, Andes now holds a 28% carried interest plus a 2% overriding royalty on Confluencia, San Bernardo, Pampa Salamanca Norte, Buen Pasto, Sierra Cuadrada and Rio Senguerr.

La Brea, El Manzano, Mina Baku and Los Buitres Blocks

In the La Brea block two successful workovers in wells PMu7 and PMu2, resulted in a significant increase in production.

On 20 November 2012 well PMu-x7 was producing 6 barrels of oil per day ("bopd") from the Agrio formation prior to a pulling operation. When returned to production, this well reached 100 bopd for the first four days then, after a week, dropped to 13 bopd and after a month, production stabilised at this level.

On 3 December 2012 well PMu-x2, which was producing 22 bopd, was worked-over in the Agrio formation. After a month, following the work over, oil production stabilised at 107 bopd.

The results from these operations indicate an Agrio formation with low-oil-permeability indicative of tight-oil behaviour. When integrated with other field information, it suggests that the Agrio formation could become an important oil producer in a tight-oil formation. Further studies will be conducted to properly address the Agrio formation reservoir behaviour and the well production decline curves.

Ñirihuau Block

As part of its exploratory commitments in Ñirihuau Sur, Chubut Province a first stage geochemical survey was conducted. The object of the program, which was to detect surface hydrocarbon seepage and determine its concentration and composition at a regional scale, was successfully accomplished. The soil gas samples collected were analysed by Geofrontier in Dallas Texas and the results were very promising. In particular an area in the northeast of the block a higher concentration of methane and ethane was detected which indicates the presence of hydrocarbons. This information will be integrated with seismic and geological data to determine the prospectivity of the area to be followed by a second campaign of high resolution geochemical analyses, with the objective of identifying a potential drilling location.

Llanos and Valle Medio del Magdalena

At the end of the year, Andes were awarded and signed contracts for eight exploration blocks in Colombia. Since then, several discoveries have been made in the surrounding areas increasing the potential of the blocks. Four of the eight blocks have been farmed-out and we are in advance discussions with several parties who are interested in the other four blocks.

Other Interests

Andes is also looking for opportunities to further grow in Colombia. After the year end Andes entered into a JV agreement with a company with production and exploration assets in Brazil and also acquired 100% of the issued share capital of Kilwer S.A., Ketsal S.A. and MGM International S.R.L..

1. GENERAL INFORMATION

1.1 Introduction

The financial information set out in this announcement does not comprise the Group's statutory accounts for the years ended 31 December 2012 or 31 December 2011.

The financial information has been extracted from the statutory accounts of the Company for the years ended 31 December 2012 and 31 December 2011. The auditors reported on those accounts; their reports were unqualified and did not contain a statement under Section 498(2) or Section 498(3) of the Companies Act 2006. The auditors' report for the year ended 31 December 2011 did include emphasis of matter paragraphs relating to Empresa Distribuidora de Electricidad de Mendoza S.A.'s ("EDEMSA") ability to continue as a going concern. EDEMSA was a subsidiary of Andes prior to the demerger completed in July 2012 and referred to in note 1.6 below.

The Company has produced its statutory accounts for the year ended 31 December 2012 in accordance with International Financial Reporting Standards as adopted by the European Union and in accordance with the Group's accounting policies that are unchanged from those set out in the 2011 statutory accounts.

The statutory accounts for the year ended 31 December 2011 have been delivered to the Registrar of Companies, whereas those for the year ended 31 December 2012 will be delivered to the Registrar of Companies following the Company's Annual General Meeting.

1.2 Prior period adjustment

After due consideration a determination has been made that a deferred tax provision should have been recognised at the time of the acquisitions of AEN Energy Holdings SPC and Gecoil y Cia. S.A. in 2011. The net assets acquired were recognised at fair values and a deferred tax liability has now been recognised based on the difference between the tax base cost and fair values of the net assets. The impact of these adjustments are summarised below:

The restatement had no impact on the Group's financial position as at 1 January 2011.

1.3 Exceptional items

In 2011, as a result of the acquisitions of Grecoil y Cia S.A. and AEN Energy Holdings SPC, the Group recognised an exceptional gain arising from the difference between the consideration paid and the fair value of the net assets acquired. Following restatement of deferred tax arising on these acquisitions, the restated exceptional gain before tax was US$1,129,497 (US$14,212,497 after tax) as detailed in note 1.2 above.

1.4 Taxation

*See note 1.2

The tax rate used for the 2012 and 2011 reconciliations above is the corporate tax rate of 35% payable by corporate entities in Argentina on taxable profits under tax law in that jurisdiction. There is no tax arising on any items within the consolidated statement of comprehensive income.

The Group is liable to pay a minimum notional income tax at the applicable tax rate (1%), calculated on the amount of computable assets at the closing of the financial year. This tax is supplementary to income tax and the Group's tax liability in each fiscal year will be the higher of the minimum notional income tax and the income tax for the year. If the minimum notional income tax for a given financial year exceeds the amount of income tax, such excess may be carried forward as a partial payment of income tax for any of the ten following fiscal years.

1.5 (Loss)/earnings per share

Basic earnings per share is calculated by dividing the net profit for the year attributable to ordinary shareholders of the Group by the weighted average number of ordinary shares outstanding during the year. The basic and diluted earnings per share are the same as there are no instruments that have a dilutive effect on earnings. Adjusted basic and diluted (loss)/earnings per share are presented after adjustment of exceptional items.

*See note 1.2

1.6 Discontinued operations

On 9 June 2012 the Company announced its intention to separate into two businesses. The separation was effected by a way of a demerger of the utility operations into a new company called Andina plc with the Company remaining the ultimate holding company for the E&P businesses. The demerger was completed on 11 July 2012.

The demerger was effected through a capital reorganisation, capitalisation, and reduction of capital. This involved a consolidation and sub-division of Andes's share capital, a capitalisation of Andes's reserves and a reduction of Andes's capital and share premium.

The net assets transferred totalled US$108,803,645 compared to the IFRIC 17 transfer value of US$116,463,959 resulting in a gain of US$7,660,314.

As a result of the demerger the results of the utility operations have been classified as discontinued operations in these financial statements.

The difference between the fair values of the operations transferred and the carrying amount of the Company's investment in its former subsidiaries is recognised in the Company's income statement as a separate line item.

The assets and liabilities transferred were:

The following amounts are included for the utility operations in the income statement within profit/loss for the year from discontinued operations:

The profit for the year from discontinued operations as presented in the income statement is comprised as follows:

1.7 Post balance sheet events

On 11 March 2013 the Company acquired 100% of the issued share capital of Kilwer S.A. ("Kilwer"). The consideration for the acquisition was satisfied by (i) the issue of 60,676,666 ordinary shares of 10 pence per share in Andes, to the vendors of Kilwer; (ii) the issue of a US$10,000,000 convertible bond with a term of 5 years and an interest rate of 11% per annum; and (iii) the issue of a US$25,000,000 bond with a term of 10 years and an interest rate of 11% per annum.

Based on the unaudited financial statements of the acquiree as at 30 September 2012 and a provisional valuation report the estimated financial effect of the acquisition is summarised below:

On 11 April 2013 the Company acquired 100% of the issued share capital of Ketsal S.A. ("Ketsal"). The consideration for the acquisition was satisfied through (i) the issue of 82,781,457 ordinary shares of 10 pence per share in Andes, to the vendors of Ketsal and (ii) the issue of a US$56,000,000 bond with a term of 10 years and an interest rate of 8% per annum.

Based on the unaudited financial statements of the acquiree as at 31 December 2012 and a provisional valuation report the estimated financial effect of the acquisition is summarised below:

On 29 April 2013 the Company exercised its option to convert the principal amounts of the convertible loans due to the vendors of Kilwer and Ketsal in accordance with the terms of the respective stock purchase agreements.

Under the terms of the Kilwer stock purchase agreement the principal outstanding and interest due for the period from 11 March 2013 to 29 April 2013 on the US$10,000,000 convertible loan, was satisfied by the issue of 19,008,166 new ordinary shares at a price of 35p per share.

Under the terms of the Ketsal stock purchase agreement the principal outstanding and interest due for the period from 11 April 2013 to 29 April 2013 was satisfied by the issue of 115,183,413 new Ordinary Shares at a price of 32p per share.

MGM International S.R.L

On 4 June 2013 the Company acquired 100% of the issued share capital of MGM International S.R.L., which has a 49.92% interest in a joint venture which operates two oil producing fields in the province of Mendoza. The primary reason for the acquisition was to increase Group's reserves and production in Argentina. The initial net production for the Group is 1,089 bopd and net proven reserves are 3.3 million bbls. The initial consideration for the acquisition was satisfied through the issue of 29,533,333 new Andes ordinary shares. Further consideration, up to a maximum of £9,450,666 (US$14,459,519), will become payable if certain conditions are met, including the achievement of minimum production levels. Any additional consideration due will be paid in two tranches in June 2014 and June 2015 and will be satisfied through the issue of Ordinary Shares at 32 pence, subject to adjustment in the event of a capital distribution, re-organisation or re-structure. Due to the proximity of the acquisition to the approval of the financial statements, the directors have been unable to determine the fair values of both the assets and liabilities acquired and the contingent consideration.

On the same day, the Company also entered into a US$10,000,000 convertible facility agreement with Mercuria Energy Asset Management B.V. ("Mercuria"). The loan carries interest at a rate of 11% per annum, which will be capitalised, with the loan principal and accrued interest repayable 5 years from the date of drawdown. Mercuria may, at any time, convert in whole or part, the loan including accrued interest, into Andes ordinary shares at a price of 26 pence per share, subject to adjustment in the event of a capital distribution, re-organisation or re-structure.
