EBITDA for the 1st half of 2017 was negative in 1.8 million euros, penalized by non-recurrent events - the sale of 50 % of the subsidiary M-City Gliwice in – and by the foreign exchange effect in Angola.

07 | NOTES TO THE INTERIM CONSOLIDATED FINANCIAL STATEMENTS

INTRODUCTORY NOTE

Martifer SGPS, S.A., with its registered head office at Zona Industrial, town of Oliveira de Frades, in Portugal (‘Martifer SGPS’ or ‘Company’), and its group of companies (all denominated ‘Group’), have as their main activities metallic constructions (steel structures, aluminium and glass façades and infrastructures for oil & gas), the naval industry and the promotion and development of renewable energy projects (Note 3).

Martifer SGPS was incorporated on 29th October 2004, having its share capital been realized through the delivery of market valued shares that the shareholders held in Martifer Construções, S.A., a company that was incorporated in 1990 and which at that time was the holding company of the current Martifer Group.

As of the Initial Public Offering in June 2007, Martifer SGPS, S.A. shares have been listed on Euronext Lisbon.

In September 2014, Martifer SGPS’s Board of Directors decided, following the strategy to focus on the metallic constructions area, to sell its stake in Martifer Solar (composed by Martifer Solar S.A. and its subsidiaries, 55 % held by the Group). As the sale was highly likely, and the requirements of IFRS 5 were fulfilled, Martifer Solar’s assets and liabilities were classified as “non-current assets held for sale” and “liabilities associated to non-current assets held for sale”, respectively, being Martifer Solar’s Net Profit presented as “discontinued operations’ result” (Note 20). In August 2016, Martifer Solar, SA and its subsidiaries were sold, except for Martifer Solar Inc. and Martifer Silverado Fund LLC, which have been subsidiaries of the company Duelobrigatório, SA since July 2016, and this company is 55 % owned by the Group. But in relation to which there is a shareholders agreement that determines the shared control, therefore, it was included in the consolidation by the equity method.

On 30th June 2017, the Group develops its activity mainly in Western Europe (in Portugal, in Spain, in France and in the United Kingdom), in Eastern Europe (in Poland and in Romania), in the Middle East (in Saudi Arabia), in Latin America (in Colombia and in Brazil), in the Sub-Saharan Africa (in Angola and in Mozambique) and in Algeria.

The following notes have been selected in order to contribute to the understanding of the most significant changes in the consolidated financial position of the Group and its performance compared to the last annual reporting date with reference to 31st December 2016.

All the amounts presented in these notes are expressed in euros (rounded to the unit), unless otherwise indicated.

These financial statements have not been audited.

1) This company started to be consolidated using the equity method because Martifer Beteiligungsverwaltungs GmbH had sold its shares to MMC (47.8 %) and APCL Invest, S.A (50 %). 2) In July 2016, these companies were no longer part of Martifer Solar Group and were acquired by Duelobrigatório, SA, which is 55 % owned by Martifer SGPS. However, there is a loss of control caused by this operation so they are no longer consolidated by the full method. Now these companies are consolidated by the equity method.

CHANGES IN THE CONSOLIDATION METHOD

In the 1st Half 2017:

M City Gliwice Sp. Zo.o - from full consolidation method to equity method. This company ceased to be fully consolidated because Martifer Beteiligungsverwaltungs GmbH had sold its shares to Martifer Metallic Constructions SGPS (47.8 %) and APCL Invest, SA (50 %), and the last one doesn’t belong to Martifer Group.

In 2016:

Martifer Solar Inc. and MT Silverado Fund LLC - from full consolidation method to equity method. In July 2016 these companies stopped being part of the Martifer Solar Group and were acquired by Duelobrigatório, S.A., 55 % owned by Martifer SGPS, but there was a loss of control in the scope of this operation.

OTHER CHANGES IN THE CONSOLIDATION PERIMETER

In the 1st Half 2017:

Cedilhas ao Vento S.A. – Shared capital is now held by Martifer Renewables Italy BV by 91 %, by Martifer Renewables Brasil Ltda by 5 % and by MSPAR Energia e Participações, SA by 4 %. In 2016 Cedilhas ao Vento S.A. was 100 % owned by Martifer Renewables Italy BV.

In 2016:

Martifer Energy Systems SGPS, S.A. and Martifer Global SGPS, S.A. were merged into Martifer Metallic Constructions SGPS, S.A. and as a consequence the first two were extinguished.

FW Warta Sp. Z.o.o - increase in shareholding from 25 % to 50 %.

The companies Martifer Inovação e Gestão, S.A., Martifer Gestão de Investimentos, S.A., Nagatel Viseu - Promoção Imobiliária, S.A. and Gebox, S.A. were merged into Martifer Construções Metalomecânicas, S.A., and as a consequence the first four were extinguished.

Duelobrigatório, S.A. - was 100 % owned by Martifer SGPS which subsequently sold 45 %, with 55 % of the latter being held.

Despite the sale of the 55 % stake held in Martifer Solar, S.A., its entities in the US will continue to be owned by Martifer Group (owned by the company Duelobrigatório).

3. OPERATIONAL SEGMENTS

The Group bases its disclosure of information on the main segments of its internal organisation for management purposes.

The Group is organised in three business areas: ‘Metallic Constructions’, ‘Naval Industry’ and ‘Renewables’ and all are coordinated and supported by Martifer SGPS.

The ‘Metallic Constructions’ business area includes all the construction activities involving metal mechanical constructions, aluminium and glass façades and infrastructures for oil & gas. ‘Naval Industry’ includes shipbuilding, ship repair services and ship reconversions. The ‘Renewables’ segment includes the promotion and development of renewable energy projects, with special emphasis on the wind sector.

Until 2016, the 'Metallic Constructions' segment included ‘Naval Industry’, but considering the characteristics of this industry and the weight it already has in the Group's total activity, from 2017 onwards it became an operating segment itself and was reported as such. Martifer Metallic Constructions, SGPS, S.A. remains as the sub holding aggregator of the operational segments 'Metallic Constructions' and 'Naval Industry'. The information for 2016 has been disaggregated to allow its comparability with the 2017 information.

The amounts presented in ‘Others’ are related to the services rendered by Martifer SGPS, S.A..

The accounting policies used in the preparation of the information by each business segment is the same as the ones used in the preparation of the attached financial statements (Note 1).

On 30th June 2017 and 2016, the breakdown of sales and services rendered by operational segments is as follows:

SALES TO EXTERNAL CUSTOMERS INTERSEGMENT SALES TOTAL 6M' 2017 6M' 2016 6M' 2017 6M' 2016 6M' 2017 6M' 2016 Metallic Constructions 57,144,999 74,424,570 8,243,683 6,823,895 65,388,682 81,248,465 Naval Industry 30,452,264 18,041,060 507,181 531,502 30,959,445 18,572,562 Renewables 6,116,267 5,368,167 400,488 325,744 6,516,755 5,693,911 Others - - 250,640 541,564 250,640 541,564 93,713,529 97,833,797 9,401,992 8,222,705 103,115,522 106,056,503 Intersegment eliminations (9,401,991) (8,222,706) 93,713,531 97,833,797

Sales and services rendered to external customers, by geographical origin and by segment were as follows on 30th June 2017 and 2016:

6M' 2017 6M' 2016

Iberian Peninsula Metallic Constructions 18,110,235 31,315,211 Naval Industry 30,452,264 18,041,060 Renewables 2,301,211 2,122,021 Central Europe Metallic Constructions 13,217,742 24,154,288 Renewables 3,021,693 2,935,124 Other markets Metallic Constructions 25,817,021 18,955,071 Renewables 793,363 311,023 93,713,531 97,833,797

In the 1st half of 2017, the sales and services rendered decreased by around 4 million euros compared to the same period last year. There was a reduction of around 23 % in Metallic Constructions, due to the slowdown of activity in some geographies, especially in Portugal, in Angola and in Romania, combined with the delay in starting new projects in France and in the United Kingdom, despite the fact that there was an increase in activity in Saudi Arabia. During the 1st half of 2016, there was a significant activity in Portugal due to the implementation of the Âncora Wind project and the Faro Airport, hence the sales and services rendered were significantly higher in this period.

On 30th June 2017 and 2016 the earnings before interest, taxes, amortizations, provisions and impairment losses (EBITDA) and earnings before interest and taxes (EBIT) by primary segments were as follows:

EBITDA EBIT 6M' 2017 6M' 2016 6M' 2017 6M' 2016 Metallic Constructions (1,785,563) (234,328) (3,064,154) (2,214,571) Naval Industry 3,435,509 1,819,585 3,026,473 1,419,797 Renewables 1,382,909 2,410,461 (11,952,241) (960,479) Others (68,370) 407,556 (588,870) (141,843) 2,964,485 4,403,275 (12,578,792) (1,897,095)

In the 1st half of 2017, the consolidated EBITDA recorded a positive value of 3 million euros, for which contributed the Naval Industry segment with 3.4 million euros and the Renewables segment with 1.4 million euros. The decrease in EBITDA in Metallic Constructions is due to the sale of 50 % of the subsidiary M-City Gliwice in Poland and due to the reduction in activity and the exchange rate effect in Angola. The increase in the Naval Industry is mainly due to the positive variation of the volume of activity and the increase of efficiency, reflecting a period of marked growth that the activity crosses nowadays. In what concerns Renewables, the EBITDA results from the activity of solar parks and wind farms in operation in Spain and Romania.

The Renewables segment registered in the 1st half of 2017 impairment of tangible fixed assets for the assets Babadag 1 and Babadag 2 (in Romania) wind farms amounting to around 9 million euros as a result of public regulatory changes in Romania, with impact on its EBIT.

The Group’s capital expenditures (acquisition of tangible and intangible assets) and depreciation/amortizations, by operating segments, until 30th June 2017 and 2016 were as follows:

The amount recorded in Ventinveste, S.A. results essentially from the gain on the sale of wind farm projects during the 1st half of 2017.

The information on associate companies and joint ventures is included in Note 16.

14. INCOME TAX

On 30th June 2017 and 2016, the reconciliation between current tax and income tax of each period is summarized as follows:

6M' 2017 6M' 2016

Current tax 1,427,970 948,031 Deferred tax - tax loss recognition - 225,530 Deferred tax - 225,530 Income tax 1,427,970 1,173,561

15. EARNINGS PER SHARE

Martifer SGPS only issued ordinary shares, and as such, no shares have special voting or dividend rights.

Martifer has just one type of potential ordinary dilutive shares: stock options. In order to calculate diluted earnings per share it is necessary to determine whether these stock options, independently of being or not exercisable, are diluted, which happens when the exercise price of the opting is lower than the average market price of the shares.

Since the average market price of Martifer’s shares, during the period between 1st January 2017 and 30th June 2017 was 0.25 euros, below that of the exercise price of the stock options (3.84 euros), these stock options are non-diluting because, if the options were to be exercised, the number of outstanding shares would be reduced.

Therefore, on 30th June 2017 there is no difference between the basic and diluted earnings per share. The share capital of Martifer SGPS, SA is represented by 100,000,000 ordinary shares, fully paid, representing a share capital of 50,000,000 euros.

The weighted average number of shares outstanding is deducted of 2,215,910 treasury stocks acquired by Martifer SGPS.

On 30th June 2017 and 2016, the basic and diluted earnings per share can be summarised as follows:

6M' 2017 6M' 2016

Profit for the year (I) 5,678,227 (3,238,863) Weighted average number of shares outstanding (II) 97,784,090 97,784,090 Basic and diluted earnings per share (I) / (II) 0.0581 (0.0331) from continuing operations 0.0581 (0.0134) from Assets held for sale - (0.0198)

1) The amount of the financial investment includes Goodwill of 667,240 euros on 30th June 2017 and of 639,342 euros on 31st December 2016. 2) At the end of 2016, the Group's holding in Duelobrigatório SA was considered totally impaired by prudence, since no return is expected due to the uncertainty on the recovery of its US investment.

In 2016, the acquisition of FW Warta, the incorporation of CNA Chantier Naval d'Arzew and the constitution of the company Duelobrigatório (that holds US companies in the Solar segment that were not sold to Voltalia Group) stand out. In the case of Duelobrigatório, although Martifer SGPS, SA owns 55 % of its share capital, the control is shared with the other shareholder as a result of a shareholder agreement. During the 1st half of 2017, M City Gliwice Sp. Zo.o. started to be consolidated using the equity method (Note 2).

20. NON-CURRENT ASSETS HELD FOR SALE AND LIABILITIES ASSOCIATED WITH THE ASSETS

Martifer SGPS, SA decided in September 2014, to focus the Group’s activity in Metallic Constructions (steel structures, aluminium and glass façades, oil & gas infrastructures and naval industry) and fulfil the active sale plan of its 55 % share of Martifer Solar. As the sale was highly likely, Martifer Solar’s assets and liabilities were classified as “non-current assets held for sale” and “liabilities associated to non-current assets held for sale” respectively, being Martifer Solar’s Net Profit presented as “result of discontinued operations”.

In August 2016, Martifer Solar, SA and its subsidiaries were sold to Voltalia Group, except for Martifer Solar Inc. and Martifer Silverado Fund LLC. These two companies became part of the company Duelobrigatório, SA in July 2016. Duelobrigatório is 55 % owned by Martifer SGPS, and for which there is shared control with the shareholder holding the remaining 45 %. Thus, both on 30th June 2017 and on 31st December 2016 there were no non-current assets held for sale.

22. BORROWINGS

On 30th June 2017 and on 31st December 2016 the borrowings can be analysed as follows:

BETWEEN 1 AND 3 BETWEEN 3 AND 5 MORE THAN 5 30th JUNE 2017 UNTIL 1 YEAR TOTAL YEARS YEARS YEARS Financial institutions borrowings: Bank loans 11,552,706 13,859,509 137,221,380 72,443,711 235,077,306 Bank overdrafts 711,367 - - - 711,367 Authorized overdrafts 3,303,829 - - - 3,303,829 Other borrowings: Other borrowings 528,715 11,166 548,874 286,140 1,374,895 16,096,617 13,870,675 137,770,254 72,729,851 240,467,397

In the 1st half of 2017, there was a 13 % reduction in debt, largely driven by the repayment of the Holding's debt as a result of the sale of the wind parks included in the Âncora Wind project. This sale was in line with the Group's strategic plan which includes the disposal of non-core assets within the scope of the consolidated debt reduction objective.

23. TRADE PAYABLES AND OTHER PAYABLES

On 30th June 2017 and on 31st December 2016, trade payables and other payables can be analysed as follows:

NON-CURRENT CURRENT 30th JUNE 2017 31st DECEMBER 2016 30th JUNE 2017 31st DECEMBER 2016 Trade payables 3,675,960 11,222,036 54,269,400 59,908,138 Other Creditors: Fixed assets suppliers 37,996 - 220,091 284,506 Related companies and other shareholders 7,851,482 7,021 469,754 983,428 Advanced payments received from customers - - 9,808,005 8,024,226 Other creditors - 1,500 2,988,314 2,370,390 Other payables 7,889,478 8,521 13,486,164 11,662,550

Total 11,565,438 11,230,557 67,755,563 71,570,688

The value of non-current suppliers on 31st December 2016 is mainly related to a partnership celebrated in the past for the development of real estate projects in Poland and the settlement of the balance will be done in accordance with the disposal of the said projects, thus not having a specific maturity date. The variation verified is mainly due to M City Gliwice Sp. Zo.o.’s change its consolidation method, to the equity method.

On 30th June 2017 and on 31st December 2016, the caption ‘Related companies and other shareholders’ includes balances payable to suppliers resulting from the Group’s operating activities, as well as from tangible and intangible asset acquisitions. The Board of Directors believes that the carrying amount of these balances is very similar to their fair value and that the effect of the financial discounts of these amounts is not material

The increase on ‘Related companies and other shareholders’ as of 31st December 2016 is related to the change in the method of consolidation of the company M City Gliwice Sp. Zo.o, which start to be consolidated using the equity method and its balances with other Group companies ceased to be eliminated in the consolidation process.

24. PROVISIONS

The information related with ‘Provisions’ on 30th June 2017 and on 31st December 2016 can be detailed as follows:

The amount of the transfers in the caption 'Contractual obligations' on 30th June 2017 is essentially related to the provision constituted referring to Duelobrigatório.

25. OTHER CURRENT LIABILITIES

On 30th June 2017 and on 31st December 2016, other current liabilities are as follows:

30th JUNE 2017 31st DECEMBER 2016

Accrued expenses Accrued Expenses - Work in progress 5,678,178 - Holiday pay and bonuses 3,458,476 3,357,129 Interest borne but not yet overdue 369,385 874,408 Production performed by third parties not yet invoiced 27,452 68,797 Other accrued expenses 1,995,554 2,124,402 11,529,045 6,424,736 Deferred income Production invoiced and not yet performed 46,236,832 46,032,883 Subsidies / Government grants 360,918 387,293 Other deferred income 7,608,308 6,364,838 54,206,058 52,785,014

65,735,102 59,209,750

The caption ' Accrued Expenses - Work in progress ' is related essentially to work done on the construction contracts in progress for which invoices have not yet been received.

The 'Other accrued expenses' correspond to other supplies and services rendered by third parties until 30th June 2017 for which invoices were received after this date.

The caption 'Other deferred income' as of 30th June 2017, as well as on 31st December 2016, results essentially from the recognition of the deferred income attributed to the green certificates in Eviva Nalbant S.R.L..

26. CONTINGENT ASSETS AND LIABILITIES

On 30th June 2017, the contingent liabilities are as follows:

a) 1. On 29th October 2009, Martifer Polska, in consortium with Ocekon Engenharia sro (Slovakia), entered into an agreement with Energomontaz-Poludnie SA for the works, whose purpose was to manufacture, execute, deliver and mount the steel roof of the Baltic Arena stadium in Gdansk, Poland, worth approximately 11.3 million euros. On 2nd September 2010, Martifer received from Energomontaz a notice of immediate termination of the agreement, without prior notice. The reason for the breach of contract was the delay in the execution of the work, which in Martifer's opinion is totally unfounded and ineffective. On 17th December 2010, Martifer filed a lawsuit against Energomontaz, requiring a value of approximately 12.6 million euros, including interest, cost of capital involved and total damage caused to Martifer due to lack of cooperation. This lawsuit was suspended due to the Energomontaz - Poludnie S.A’s insolvency proceedings.

2. On 17th January 2012, Energomontaz filed a lawsuit against Martifer and Ocekon Engenharia sro for a total amount of 5.7 million euros. The hearings are in progress and witnesses were examined in 2015. In March 2017, the court dismissed the case against Ocekon Engenharia sro, as it was removed from the commercial register. More audiences are scheduled for 2017.

3. Meanwhile, Energomontaz has entered into bankruptcy proceedings. In April 2013, the list of claims by Martifer in the amount of 16.9 million euros was submitted to the insolvency administrator. However, the court did not recognise the list of the claims submitted by Martifer, so the claim was neither recognized nor accepted by the Court.

Martifer Group has recognized in its financial statements the risk of losses related to accounts receivable, increase in income from work in progress and from the bank guarantee executed. Therefore, it considers that the framework of this process is duly reflected in the financial statements.

b) The Romanian subsidiary, Martifer Constructii, acquired on 9th March 2007 a plot of land in Aricesti, Prahova province, in Romania, for approximately 8.2 million RON. The referred acquisition is under a judicial dispute, currently pending judicial action, with its terms running under appeal, being expected one of two outcomes:

1. The Court rules a decision under which the land is maintained in property of the Romanian State, initial owner, in which Martifer Constructii shall have the right to an indemnity, at least, in an equivalent amount to the price paid for the land when it was acquired;

2. The Court rules a decision under which the land transits to Martifer Constructii’s assets, with Martifer Constructii acquiring the totality of the rights of the land.

According to the developments on the current judicial action, Martifer considers as most probable the happening of the scenario presented in 1), with a high probability of recovery of the amount paid when the land was acquired.

The Group's expectation is that no losses will occur with these processes over and above the ones already recognized in its financial statements.

27. COMMITMENTS

28. RELATED PARTIES

Group companies have commercial relations with each other that qualify them as related party transactions. All of these transactions are performed on an arm’s length basis.

Consequently, all these transactions are eliminated, since the consolidated financial statements disclose information regarding the holding company and its subsidiaries as if they were a single entity.

The balances resulting from the transactions performed with associate and jointly controlled companies, accounted through the equity method, are not eliminated. The amount of the balances not eliminated is approximately 53 million euros, with special regard to the accounts receivable from Ventinveste and some companies in Poland in the Metallic Constructions segment.

Besides current transactions, some relating to civil construction works done with the Mota-Engil Group and others associated with real estate management projects under way done by Estia Group, there are no other significant balances and transactions performed with related parties during the period ended on 30th June 2017 that significantly affected the financial position or performance of the Group.

29. SUBSEQUENT EVENTS

Since the reference date of the results, no facts that affect the released financial information occurred.

30. APPROVAL OF THE FINANCIAL STATEMENTS

The accompanying consolidated financial statements were approved by the Board of Directors on 28th August 2017.
