GTECH S.p.A. LAUNCHES AN OFFER AND A CONSENT SOLICITATION IN RESPECT OF THE SUBORDINATED NOTES DUE 2066

ROME, ITALY and PROVIDENCE, RHODE ISLAND (US), December 18, 2014 — GTECH S.p.A. (formerly known as Lottomatica S.p.A.) (“GTECH” or the “Issuer”) announced today its invitations to holders (the “Holders”) of its €750,000,000 Subordinated Interest-Deferrable Capital Securities due 2066 (Regulation S ISIN XS0254095663 and Rule 144A ISIN XS0254095747) (the “Capital Securities”) to:

(a)                       tender any and all Capital Securities for purchase by the Issuer for cash (the “Offer”); and

(b)                       consider and, if thought fit, approve the Proposals (as defined below), by separate Extraordinary Resolutions pursuant to the Conditions and the Trust Deed (the “Consent Solicitation”).

The Offer and the Consent Solicitation are made on the terms and subject to the conditions set out in the invitation memorandum dated 18 December 2014 (the “Invitation Memorandum”).

* The Total Consideration (which includes the Purchase Price, the Early Tender Premium, Accrued Interest and, if the Payment Condition is satisfied, the Consent Fee) is only available to Holders submitting a Tender Instruction prior to the Early Tender Deadline.

** Subject to the terms and conditions set out herein, Holders are eligible to receive a Consent Fee of 0.25 percent. of the aggregate principal amount of the Capital Securities which are voted in favour of each Extraordinary Resolution.

The Offer

Subject to the offer restrictions set out in this announcement and the Invitation Memorandum, the Offer is being made in respect of any and all of the outstanding Capital Securities. If the Issuer accepts any valid tenders of Capital Securities for purchase pursuant to the Offer, it will accept all such offers that have been made. Capital Securities that are not accepted for purchase pursuant to the Offer will remain outstanding.

The purchase price payable for the Capital Securities accepted for purchase in the Offer (the “Purchase Price”) will be 105.75 percent. of the aggregate principal amount of such Capital Securities. In respect of any Capital Securities accepted for purchase, the Issuer will also pay any interest accrued and unpaid on the relevant Capital Securities from (and including) the interest payment date for such Capital Securities immediately preceding 23 January 2015 (the “Settlement Date”) to (but excluding) the Settlement Date (the “Accrued Interest”). The Purchase Price and the Accrued Interest will be paid on the Settlement Date.

Early Tender Premium

Each Holder which validly offers its Capital Securities for purchase in the Offer by 5:00 p.m. (CET) on 7 January 2015 (the “Early Tender Deadline”) (and does not subsequently revoke such offer) will, if such Capital Securities are accepted for purchase, receive on the Settlement Date a further cash payment (the “Early Tender Premium”) in addition to the Purchase Price and the Accrued Interest, as additional consideration for the purchase of the relevant Capital Securities, of 3.00 percent. of the aggregate principal amount of such Capital Securities.

By offering to tender its Capital Securities, a Holder will vote in favour of both Extraordinary Resolutions at the Meeting provided it has submitted its Tender Instruction by 5:00 p.m. (CET) on 14 January 2014 (the “Consent Expiration Deadline”). Any Tender Instructions received after the Consent Expiration Deadline will be treated as an offer to tender Capital Securities only and any votes included in such Tender Instruction will not be taken into account for the purposes of the Meeting. Any such Holder will not be eligible to receive the Consent Fee.

The Consent Solicitation

Concurrently, the Issuer is soliciting consents from the Holders to approve the Proposals at the Meeting. The Holders of the Capital Securities are called in a meeting on 19 January 2015, on first call, and, if necessary, on 20 January 2015 and 21 January 2015, on second and third call respectively, at 6:00 p.m. (CET) in each case, for the purpose of considering and, if thought fit, passing two Extraordinary Resolutions to:

2

(i)                                     acknowledge that Condition 6.7 (Replacement) of the Capital Securities does not apply in relation to the Offer (“Proposal 1”); and

(ii)                                  approve amendments to the Conditions and the Trust Deed as set out in the draft Supplemental Trust Deed to (a) reflect the change in the jurisdiction of incorporation of the Issuer pursuant to the Merger and to remove provisions which are no longer relevant or applicable as a result of such change of jurisdiction, including but not limited to those only applicable to Italian companies; (b) remove commercial terms that are no longer relevant and amend certain other provisions to align these with the customary terms of similar securities issued under English law (including amendments to the quorum required to pass an Extraordinary Resolution and to incorporate certain protections in favour of the Trustee); and (c) clarify that Condition 6.7 (Replacement) of the Capital Securities is not intended to be a contractual term of the Capital Securities and is instead only an indication of the Issuer’s intention (“Proposal 2” and together with Proposal 1, the “Proposals”).

Subject to the terms and condition specified in the Invitation Memorandum including the Payment Condition being satisfied, the Consent Fee will be payable for votes in favour of each Extraordinary Resolution. In order to be eligible for the Consent Fee, a Holder must deliver or procure the delivery of a valid Tender Instruction or a valid Consent Instruction including a vote in favour of one or both of the Extraordinary Resolutions (which is not validly revoked) by the Consent Expiration Deadline. The Consent Fee will be 0.25 percent. of the aggregate principal amount of the Capital Securities which are voted in favour of each Extraordinary Resolution.

All valid Tender Instructions submitted by the Consent Expiration Deadline will, subject as described in the Invitation Memorandum, include a vote in favour of both Extraordinary Resolutions. As a result, subject always to satisfaction of the Payment Condition, a Holder who validly submits a Tender Instruction by the Consent Expiration Deadline will receive a payment of the Consent Fee in respect of its vote in favour of both Extraordinary Resolutions, provided such instruction is not validly revoked, resulting in an aggregate Consent Fee of 0.5 percent. of the aggregate principal amount of the Capital Securities which are the subject of such Tender Instruction.

The notice of meeting has been published on the website of the Luxembourg Stock Exchange (www.bourse.lu), on the Issuer’s website (www.gtech.com — section entitled “Governance — Documents and Reports — Governance Documents — Shareholders’ and Noteholders’ Meetings — Meeting of Holders of Capital Securities January 19-20-21, 2015”), as well as on the “1info” central storage device (www.1info.it), and has been distributed to the Holders through Euroclear and Clearstream. An extract from the notice has been published in Italian in “Il Sole 24Ore” on 18 December 2014.
