Results at 31 December 2012

The Board of Directors of Maire Tecnimont S.p.A. also examined and approved the draft Company Financial Statements at 31 December 2012 and Group consolidated Financial Statements at 31 December 2012.

Oil, Gas & Petrochemicals BU

At 31 December 2012, the revenues of the Oil, Gas & Petrochemicals BU, that is the Group core business, amount to €1,810.1 million, decreasing (9.5%) versus €2,001 million at 31 December 2011.

The Business profit¹ at 31 December 2012 is equal to €165 million, versus €216.3 million at 31 December 2011, down 23.7%, as a result of the lower production volumes generated and a lower average profitability of projects against 2011, as well as of the budget review for some projects.

At 31 December 2012 the EBITDA amounts to €91.1 million, with an EBITDA margin equal to 5%, down 29.6% against 31 December 2011 when it was equal to €129.4 million (6.5% on revenues), primarily due to the Business Profit downturn.

The Backlog of the Oil, Gas & Petrochemicals BU at 31 December 2012 is equal to €3,141.7 million, down 3.6% versus €3,257.9 million at 31 December 2011. The BU backlog accounts for 59.9% of the Group total backlog. The new contracts record a substantial increase (equal to +51.3%) against the previous year, confirming the Company policy focus on its core business. The main acquisitions were made in the petrochemical sector (Etileno XXI in Mexico, Slovnaft in Slovakia, LDPE Sadara and HDPE Sabic in Saudi Arabia), in oil&gas (Tempa Rossa, Burgas Lukoil, Mostorod ERC refinery in Egypt) and in fertilizers (Iowa USA). The BU engineering services amount to €85.6 million, increasing by approximately 24% versus 2011 when this value was equal to €69.2 million.

Power BU

At 31 December 2012 the revenues of the Power BU amount to €177.5million, decreasing substantially (-61.0%) against €454.8 of the same period of 2011, in line with the business refocus strategy and as a natural consequence of the termination of all EPC contracts in Latin America, as confirmed (i) by the final closing –announced last 27 March 2013 – for the disposal of the special purpose vehicle “Mabe” (contractor of the three Brazilian power projects Pecem I, Pecem II and Itaqui) to MPX Energia SA and EDP Energias do Brasil; (ii) by the general settlement agreement closed in November 2012 with Colbun which led to the conclusion of the relevant arbitration proceeding; (iii) by the termination of the Bocamina contract notified to the client Endesa Chile in December 2012 and by the full booking in the financial year 2012 of the collected guarantees, without prejudice to every Tecnimont’s right.

The Business Profit is negative for €208.8 million against 31 December 2011 when it was negative €372.5 million. Such performance factors in the economic effects of the Latin American projects.

The EBITDA at 31 December 2012 is negative for €216.5 million, improving against 31 December 2011 when it was negative for €390.9 million, factoring in the Business Profit performance.

The Backlog of the Power BU at 31 December 2012 is equal to €30.8 million (down 89.8% versus €301.2 million at 31 December 2011) in line with the strategic focus on the core business. The Backlog of the Power BU accounts for 0.59% of the Group total backlog, primarily attributable to service activities.

Infrastructure & Civil Engineering BU

At 31 December 2012 the revenues of the Infrastructure & Civil Engineering BU amount to€199.2 million, up 4.5% against 31 December 2011, when they were equal to €190.6 million. Such change results from the natural evolution of the BU activity.

The Business Profit at 31 December 2012 is negative for€24.3 million (recording a 30% improvement versus 31 December 2011, when it was negative for €34.7 million).

The EBITDA at 31 December2012 is negative for€33.8 million(improving against 31 December 2011, when it was negative for €43.5 million).

At 31 December 2012 the Backlogis equal to €2,071.8 million,up 60.1% versus €1,293.7 million at 31 December 2011. This increase is attributable to the inclusion in the backlog of the overall value of the Milan-Genoa High Speed/High Capacity railway line project (“Terzo Valico dei Giovi”) assigned to COCIV consortium (of which Tecnimont is a member with a 20% holding equal to €960 million), following to the announced start of the works of the second construction lot on 26 March 2013.

Consolidated operating results at 31 December 2012

Revenues of the Maire Tecnimont Group at 31 December 2012 amount to €2,186.8million, down 17.4% versus €2,646.3 million at 31 December 2011. Such result is primarily attributable to the substantial reduction in the Power BU revenues.

At 31 December 2012, the Business profit is negative for€68.0million, improving (+64.4%) against 31 December 2011 when it was negative for €190.9 million. This result is impacted by the economic effects related to the events regarding the power contracts in South America, as well as by the one-off results of the Infrastructure & Civil Engineering BU. The Business Profit net of such one-off effects would be positive andequal to €173.6 million.

The Business Margin at 31 December 2012 is negative for 3.1%, recording an improvement against the same period of 2011 when it was negative for 7.2%.

The G&A costs at 31 December 2012 amount to €91.0 million, recording a decrease versus €110.1 million at 31 December 2011. Such structural result is ascribable to the benefits deriving from the re-organizations implemented and from the continuous commitment to cost reduction.

The non-capitalized Research & Development costs at 31 December 2012 amount to about €0.2million, versus €4.1 million at 31 December 2011.

At 31 December 2012 the EBITDA is negative for€159.2 million (-7.3% on revenues) substantially improving (+47.8%) against 31 December 2011 when it was negative for €305.1 million (-11.5% on revenues).

After depreciation and amortisation for risks and charges, the EBIT at 31 December 2012 is negative for €187.4 million, down 44.7% against 31 December 2011 when it was negative for €338.7 million.

The Net Financial Income at 31 December 2012 is negative for€45.1 million, against 31 December 2011 when it was negative for €16.7 million. Such result is primarily influenced by the increased interest paid on medium- and long-term loans and by the lower interest collected, as well as by the charges on exchange rate fluctuation hedging instruments.

The tax value is equal to €24.8 million, against €9.2 million recorded at 31 December 2011. This item factors in the loss for period and the consequent booking of deferred tax assets.

The Group Net Result at 31 December 2012 is negative for€207.6 million, with a decreased loss against 31 December 2011, when it was negative for €296.4 million.

At 31 December 2012 the Net Financial Position (“NFP”) is negative for€226.2 million (it was negative for €10.4 million at 31 December 2011), mostly as a result of the cash absorption following to the agreement for the transfer of Mabe special purpose vehicle in Brazil and of the collections of the guarantees by Endesa Chile relatively to Bocamina power project.

The Group Net Equity at 31 December 2012is negative for €121.8 million, recording a downturn against 31 December 2011 when it was positive for €89 millionat 31 December 2011, primarily as a consequence of the result for the period.

The Net Equity of the parent company Maire Tecnimont S.p.A. at 31 December 2012 is positive for €252.9million, against 31 December 2011, when it was equal to €269.5 million.

Backlog

In the course of 2012, the Group’s commercial activity generated new contracts for €2,601.7million, up 25.8% versus €2,068.6million at 31 December 2011. Such new contracts have been almost entirely assigned to the core business Oil, Gas & Petrochemicals while in Infrastructure & Civil Engineering – considering the progress of the Milan-Genoa (Cociv) high speed line project - the overall value of this project has been included in the backlog to the extent of the quota relating to the Group.

The Backlog of the Maire Tecnimont Group at 31 December 2012 amounts to €5,224.4million, up 8.1% versus €4,852.8 million at 31 December 2011.

Moreover, Maire Tecnimont announced the awarding of contracts and supplements for a total value of about €147 million for engineering, licensing and technology packages in the core business, while in the Infrastructure & Civil Engineering the start of the works regarding the second construction lot of the Milan-Genoa project was announced. Finally, Maire Tecnimont announced that the closing relating to the disposal of the special purpose vehicle “Mabe” in Brazil was completed.

Business outlook

The Group envisages for 2013 a return to positive margins. Such result is primarily driven by the positive performance of the Oil, Gas & Petrochemicals BU, in which new contracts are expected, confirming the industrial repositioning and in line with the strategic orientation of pursuing lower risk projects. The Group new strategic assumptions are based on a consolidation of the traditional EPC activities, with higher focus on E and EP components and on the development of the licensing and customer service activity, also as a result of the Group repositioning on new markets.
