INFORMATION DOCUMENT

CAPITAL INCREASE CHARGED TO RESERVES

ACS, ACTIVIDADES DE CONSTRUCCIÓN Y

SERVICIOS, S.A.

9 January 2019

This Information Document has been prepared pursuant to the provisions in articles 26.1 d) and 41.1d) of Royal Decree 1310/2005.

• 1 Object

  The Annual General Meeting of Shareholders of ACS, Actividades de Construcción y Servicios, S.A. ("ACS" or the "Company") held on 8 May 2018 resolved to increase the share capital of ACS charged to voluntary reserves in an amount to be determined according to the terms established in the agreement itself (the "Capital Increase"), "), as well as to simultaneously reduce the share capital of the Company by an maximum amount equal to the amount of the share capital that is actually issued as a consequence of the Capital Increase (the Capital Increase and this reduction are the "Resolution"), delegating the execution of the resolution to the Board of Directors (with express powers of substitution) (the "Resolution" pursuant to article 297.1.a) of the Capital Companies Act, approved by Legislative Royal Decree 1/2010, of 2 July (the "Capital Companies Act").

  According to the terms of the Resolution, the maximum reference fair value of the Capital Increase is 441 million euros and it may be exercised within the year following the date of the Resolution on one or two occasions at the very most, and the reference fair value is not to exceed 299 million euros in the First Execution, or 142 million euros in the second execution, in the event it is carried out.

  The Board of Directors of the Company, at its meeting held on 13 December 2018, among, and using the powers of delegation in the Resolution, resolved to carry out a Second Execution of the Capital Increase delegate indiscriminately to the Executive Commission, the Chairman of the Board of Directors and the Director and Secretary so that they may carry out any actions they deem appropriate or necessary for the execution of everything contained in the Resolution and they may sign any documents required or considered appropriate for the above-mentioned purposes.

  By virtue thereof, on 9 January 2019, resolved to carry out a Second Execution of the Capital Increase (the "Second Execution") setting the maximum reference value of said Second Execution (Amount of the Executed Option) at 142 million euros. In the event (a mere theoretical possibility) that none of the shareholders were to choose to sell their rights to the Company pursuant to the Purchase Commitment (section 2.2 below) and that the PreCot (quoted price, the reference Price used to determine the number of shares to be issued, see also section 2.2 below) coincides with the closing share price of the day before the date of this document, this Second Execution would determine a capital increase of approximately 1.30 %. However, as a consequence of the simultaneous capital reduction by means of the amortisation of shares that is mentioned in section 2.1 below, in any event following the increase and the reduction, the current share capital amount will remain unchanged.

  Pursuant to the provisions in articles 26.1.e) and 41.1.d) of Royal Decree 1310/2005, of 4 November, it is not necessary to prepare and publish a prospectus in respect of the issuance and Listing of the shares issued as a consequence of the Second Execution insofar as the existence of this information document means that a document is available with information on the number and nature of the shares and the reasons for and details of the offer.

  The purpose of this information document is to furnish the information among that mentioned above which is available as of the present date. Once the First Execution is executed and the remaining information is available, it will be disclosed as a supplement to this information document. The disclosure of the Second Execution of the Capital Increase and of the particulars thereof that are yet to be concretised by means of a supplement to this information document is scheduled to take place on 17 January 2019.

• 2 Purpose and functioning of the Capital Increase

• 2.1 Purpose

  The purpose of the transaction forming the object of this Informative Document is to offer the shareholders of the Company, in lieu of what would be an interim cash dividend, fully paid-up shares with the possibility of immediately monetising the free allotment rights corresponding to said shares through their sale to the Company at a pre-defined price.

The transaction is in line with similar transactions carried out by ACS, since 2012, and with the practices of other important listed companies in recent years. It involves remunerating the shareholder in accordance with a flexible "optional dividend" which enables to receive and retain the shares o the receipt of money in conditions which are equivalent, including as regards taxation, to those of an actual dividend.

Likewise, at the time of the Second Execution, has resolved to partially execute the capital reduction by means of the amortisation of treasury shares established in the Resolution in a nominal amount maximum equal to the actual nominal amount of the Second Execution, simultaneously thereto. With this reduction, the shareholders who decide to transfer their free allocation rights as a consequence of the Second Execution will not be subject to a dilution of their ownership interest in the Company.

2.2

Functioning

The shareholders of the Company will receive a free allocation right for each ACS share in their possession. These shall be negotiable rights, and therefore they may be transferred on the Madrid, Barcelona, Bilbao and Valencia Stock Exchanges during a term of 15 calendar days, after which the rights will automatically become newly issued shares of ACS, and they will be attributed to those who at the time are holders of free allocation rights.

Therefore, at the time of the Second Execution, the shareholders of ACS will be free to choose between:

• (a) Not transferring their free allocation rights. In such event, at the end of each trading period the shareholder will receive the fully liberated new shares to which he is entitled. This allocation of shares is not subject to withholding for tax purposes.

• (b) Transferring the entirety or part of their free allocation rights to ACS by virtue of the Purchase Commitment assumed by ACS at a guaranteed fixed price for the Second Execution (the "Purchase Commitment"). In this way, a shareholder would choose to monetise his rights, receiving the Executed Option in cash rather than receiving shares. Rights that were acquired on the secondary market cannot be transferred. The free allocation rights may only be transferred to the Company by virtue of the Purchase Commitment by the shareholders who had acquired their shares until 21 January 2019 (on the date of publication of the announcement of the Second Execution in the Mercantile Registry Official Gazette, BORME) and whose transactions had been settled until 23 January 2019 to the Sociedad de Gestión de los Sistemas de Registro, Compensación y Liquidación de Valores, S.A.U (Iberclear), both inclusive. The tax regime applying to the amount received as a consequence of choosing this option is the same as for cash dividends, therefore the amount payable to shareholders shall be subject to the relevant withholding.

• (c) Transferring the entirety or part of his free allocation rights on the market. In this case a shareholder would also choose to monetise his rights, but he would not receive a guaranteed fixed price, because the consideration for the rights would depend on the market conditions in general and on the quoted Price of those rights in particular. Amounts obtained from the sale of rights on the market will be considered as equity gain and will be subject to the corresponding withholding in accordance with the rules established in the regulations in force for taxpayers subject to Income Tax of Individuals.

Also, shareholders may combine the above options (that is, they may choose one or more of them in respect of the entirety or part of the rights and shares to which they are entitled in the Second Execution of the Capital Increase), depending on what they freely decide.

Shareholders who do not communicate a specific decision will receive the number of new shares to which they are entitled.

As stated above, shareholders will receive a free allocation right for each share of ACS of which they are holders. The number of rights required to receive a new share and the guaranteed price at whichACS shall undertake to buy the rights from those choosing to receive cash by virtue of the Purchase Commitment will depend on the quoted price of the ACS share on the days prior to the Second Execution of the Capital Increase and on the number of shares outstanding at the time. The number of rights and the final price of the Purchase Commitment are scheduled to be disclosed on 17 January 2019, by means of a supplement to this information document, and said data will be calculated by applying the formulas established in the Resolution approved by the Meeting (available at the ACS website (www.grupoacs.com) and at the CNMV website(www.cnmv.es), said formulas being laid out below.

In any event, the number of shares to be issued shall be such that the fair value of those shares calculated according to the quoted Price of the ACS share on the days before the Second Execution of the Capital Increase shall be 142 million euros. Said amount has been established pursuant to the provisions in the Resolution of the Annual General Meeting of Shareholders.

In this way, the approximate value of each free allocation right is 0.449 euros. This shall also be the approximate price of the ACS Purchase Commitment.

Specifically, the number of rights required in order to receive a new share and the price of the Purchase Commitment in respect of those rights shall be calculated as follows:

No. of rights = NTAcc/ (142,000,000/PreCot), (rounded to the next highest whole number).

Where,

"No. of rights" shall be the number of rights required in order to receive a new share of ACS in the Second Execution.

"NTAcc" shall be the number of shares outstanding on the date of the Second Execution of the Capital Increase (as of the date of this document, 314.664.594 shares). For the purpose herein, the date of the Second Execution shall be that on which the Executive Commission, the Chairman of the Board of Directors or the Director-Secretary General, by virtue of the delegation of powers executed by the Board of Directors at its meeting of 19 December 2018, carries out the arithmetical operations resulting from the application of the formulas mentioned herein, in order to calculate the provisional number of shares to be issued, the number of free allocation rights required for the allocation of a share, the "PreCot" (quoted price) and the maximum nominal amount of the Capital Increase as a result of the Second Execution, which is scheduled to take place on 17 January 2019;

"PreCot" shall be the (simple) arithmetic mean of the weighted average quoted prices of the Company share on the Madrid, Barcelona, Bilbao and Valencia Stock Exchanges in the 5 stock exchange sessions of 10, 11, 14, 15 and 16 January 2019, rounded to the nearest thousandth of euro and, if there is a half thousandth euro, it will be rounded to immediately higher thousandth of euro

If necessary, ACS shall waive the number of free allocation rights required to guarantee that the number of shares to be issued in the Second Execution and the number of rights required to receive a share is a whole number rather than a fraction.

"Fixed price of the Purchase Commitment" = PreCot / No. of rights rounded to the nearest thousandth of euro and, if there is a half thousandth euro, it will be rounded to immediately higher thousandth of euro.

Where "PreCot" and "No. of rights" have the meanings stated above.
