ANNUAL GENERAL MEETING OF SHAREHOLDERS

GENERAL INFORMATION

This Proxy Statement is being provided to solicit proxies on behalf of the Board of Directors of Atento S.A. (the “Company,” “Atento,” “we” or “us”) for use at the 2019 Annual General Meeting of Shareholders (the “Annual Meeting”) to be held on Friday, May 31, 2019, at 10:00 a.m., Central European Time, at the office of Arendt & Medernach SA, 41A avenue JF KennedyL-2082 Luxembourg, and any adjournment or postponement thereof. We expect to first make this Proxy Statement available, together with the Company’s stand-alone and consolidated annual accounts for the financial year ended December 31, 2018 and Annual Report on Form20-F for the year ended December 31, 2018 (the “Annual Report”), to shareholders on or about May 1, 2019.

Foreign Private Issuer

We are a “foreign private issuer” within the meaning of Rule3b-4 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as a result, we are not required to mandatorily comply with U.S. federal proxy requirements.

Internet Availability of Annual Meeting Materials

We have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending a notice regarding Internet availability of proxy materials to our shareholders of record as of the close of business on April 11, 2019 (the “Record Date”). All shareholders will have the ability to access the proxy materials on the website referred to in the notice or to request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the notice. You will not receive a printed copy of the proxy materials unless you request one in the manner set forth in the notice, or unless you are a registered shareholder. This permits us to conserve natural resources and reduces our printing costs, while giving shareholders a convenient and efficient way to access our proxy materials and to exercise the voting rights attendant to their shares at the Annual Meeting.

We intend to mail the notice on or about May 1, 2019 to all shareholders of record. On that same date, we will also mail a printed copy of this Proxy Statement, the Company’s stand-alone and consolidated annual accounts for the financial year ended, Annual Report and form of proxy to shareholders who had previously requested printed copies and to registered shareholders.

Who May Vote

Only holders of record of our ordinary shares at the close of business on the Record Date will be entitled to notice of the Annual Meeting. Holders of record of our ordinary shares at the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the

Record Date, 74,300,199 ordinary shares were issued and outstanding and entitled to vote at the Annual Meeting and 1,106,158 additional ordinary shares were held as treasury shares . Each ordinary share is entitled to one vote at the Annual Meeting.

What Constitutes a Quorum

No quorum is required for any ordinary resolutions to be considered at the Annual Meeting.

BrokerNon-Votes and Abstentions

Brokernon-votes occur when brokers holding shares in street name for beneficial owners do not receive instructions from the beneficial owners about how to vote their shares and the broker is unable to vote the shares in its discretion in the absence of an instruction. An abstention occurs when a shareholder withholds such shareholder’s vote on a particular matter by checking the “ABSTAIN” box on the proxy card.

Under the current New York Stock Exchange rules as applicable to foreign private issuers, your broker will not be able to vote your shares with respect to any of the proposals or other matters considered at the Annual Meeting, in each case unless you have provided instructions to your broker. We strongly encourage you to provide instructions to your broker to vote your shares and exercise your right as a shareholder. A vote will not be cast in cases where a broker has not received an instruction from the beneficial owner.

With respect to all of the proposals or other matters considered at the Annual Meeting, only those votes cast “FOR” or “AGAINST” are counted for the purposes of determining the number of votes cast with respect to each such proposal. Abstentions are not considered votes cast and have no effect on the outcome of any of the proposals.

Voting Process and Revocation of Proxies

If you are a shareholder of record, and you received your proxy materials by mail or if you requested paper copies of the proxy materials, you can vote by mail by marking, dating, signing and returning the proxy card in the postage-paid envelope. Submitting your proxy by mail will not affect your ability to attend the Annual Meetingin-person and vote at the Annual Meeting.

If your shares are held in “street name,” meaning you are a beneficial owner with your shares held through a bank or brokerage firm, you will receive instructions from your bank or brokerage firm. You must follow the instructions of the holder of record in order for your shares to be voted.

The Company will retain an independent tabulator to receive and tabulate the proxies.

If you submit a proxy and direct how your shares will be voted, the individuals named as proxies will vote your shares in the manner you indicate. If you submit a proxy but do not direct how your shares will be voted, the individuals named as proxies will vote your shares “FOR” the election of each of the nominees for director and “FOR” each of the other proposals identified herein.

2

It is not expected that any other matters will be brought before the Annual Meeting. If, however, other matters are properly presented, the individuals named as proxies will vote in accordance with their discretion with respect to such matters, to the extent that such discretion is duly provided for by proxy in accordance with Luxembourg law.

A shareholder who has given a proxy may revoke it at any time before it is exercised at the Annual Meeting by:

• attending the Annual Meeting and voting in person;

• delivering a written notice, at the address given below, bearing a date later than that indicated on the proxy card, but prior to the date of the Annual Meeting, stating that the proxy is revoked; or

• signing and delivering a subsequently dated proxy card prior to the vote at the Annual Meeting.

You should send any written notice or new proxy card to Atento S.A., c/o Broadridge Financial Solutions, Inc., 51 Mercedes Way, Edgewood, New York 11717. If you are a registered holder you may request a new proxy card by contacting our Investor Relations Department at +55 113 2935 926 orshay.chor@atento.com.

Any shareholder owning shares in street name may change or revoke previously given voting instructions by contacting the bank or brokerage firm holding the shares or by obtaining a legal proxy from such bank or brokerage firm and voting in person at the Annual Meeting. Your last vote, prior to or at the Annual Meeting is the vote that will be counted.

To be admitted to the Annual Meeting, you will need a form of photo identification (such as a driver’s license or passport), and if you hold your shares in street name you must also bring valid proof of ownership of your shares on the Record Date or a valid legal proxy from the holder of record. If you are a shareholder of record, you will be admitted to the Annual Meeting only if we are able to verify your shareholder status by checking your name against the list of registered shareholders on the Record Date. If you hold your shares in street name through a bank or brokerage firm, a brokerage statement reflecting your ownership as of the Record Date or a letter from a bank or broker confirming your ownership as of the Record Date is sufficient proof of ownership to be admitted to the Annual Meeting.
