The total amount of the transaction shall be Ch$111.453.169.600 (one hundred and eleven billion four hundred fifty three million one hundred sixty nine thousand six hundred pesos, national currency) in the event of the acquisition of the 16,390,172 shares that represent 4.44% approximately of the currently issued, subscribed and paid-up shares of the Company, at a price of Ch$6,800 (six thousand eight hundred pesos, national currency) for each share of the Company sold under the Offer.

Should the number of shares subject to acceptance of the Offer be less than such amount, the total amount of the transaction will be the result of multiplying the number of shares received (including those resulting from the conversion of American Depositary Shares (“ADS”) with respect to the which the offer has been accepted in the United States of America) by the price contemplated in the Offer for each share.

3.2. Shares underlying the Offer and markets in which it is simultaneously carried out

The Offer is made for 16,390,172 shares of the Company, which to date approximately amount to 4.44% of its equity capital (a percentage that is calculated including those currently represented by ADSs).

The Offer is only one and is simultaneously made on the local market (Chile) managed by the Chilean Tender Agent and in the United States of America managed by the U.S. Tender Agent (as these terms are defined below). For the purposes of the Offer in the United States of America, a tender offer statement in English

language will be filed with the US Securities and Exchange Commission and distributed in such jurisdiction the day following the date of publication of this notice of commencement. (the “U.S. Offer Document”). A copy of the US Offer Document together with the annexes thereto, as well as a free translation thereof into Spanish, will be made available to the public and those interested in the Offer at the same information places referred to in the Section 11 (“Information Places”) of this notice of commencement, in the same day in which it is distributed in the United States of America. The Offer is made, in Chile, in accordance with the provisions set forth in the Securities Market Law and other applicable regulations, and in the United States of America in accordance with Regulation 14D and Regulation 14E, both of the U.S. Securities Exchange Act of 1934.

Those who are holders of ADSs or shares in CCU and wish to participate in the Offer in the United States of America must follow the procedures to be established in the US Offer Document. In the case of the ADSs, such procedures will entail the cancellation of the ADSs and the withdrawal of the common shares represented by ADSs from CCU's ADS program; in order that the Offeror shall receive and exclusively acquire CCU common shares.

For the purposes of managing the Offer in the United States of America, the Offeror has hired Goldman Sachs & Co. LLC as Dealer Manager and U.S. Settlement Agent (in the latter capacity, the “U.S. Settlement Agent”), Computershare Trust Company, N.A. and Computershare Inc., both as U.S. Share Tender Agent (in such capacity, the “US Share Tender Agent”), and as ADS Tender Agent (in such capacity, the “ADS Tender Agent”, and in both capacities as the “U.S. Tender Agent”), and Georgeson LLC as Information Agent. For all purposes of the Offer, the U.S. Tender Agent has been hired by the Offeror to facilitate the tendering of shares and ADSs in the United States of America, and thus, given that it is duly authorized to provide such service in such country, it shall be understood that it will act, both in its capacity as U.S. Share Tender Agent and in its capacity as ADS Tender Agent, on account of Banchile Corredores de Bolsa S.A, who acts as tender agent for purposes of the Securities Market Law (the “Chilean Tender Agent”) and ultimately on account of the Offeror.

3.3. Proration mechanism

In the event that the number of shares contemplated in the acceptances of this Offer, considering both common shares in CCU and those represented by ADS, exceeds the 16,390,172 issued, subscribed and paid-up shares in CCU, the Offeror shall buy the shares offered on a pro rata basis from each of the accepting shareholders (including those who have accepted the Offer by delivering their shares or ADSs to the US Tender Agent), applying the apportionment factor that will be determined immediately after the Expiration Date.

The apportionment factor applicable to the shares accepted in the Offer will be the result from dividing (i) the total number of shares offered by the Offeror to acquire (16,390,172 shares in CCU), by (ii) the total number of shares that CCU shareholders agree to sell in this Offer, both in Chile and in the United States of America (including the total number of shares represented by ADSs that the ADS holders agree to sell according to the procedure to be described in the US Offer Document). In turn, the number of shares to be acquired by IRSA from each shareholder who accept the Offer will be the whole number of shares resulting from multiplying the total number of shares offered to sell in the Offer by the respective shareholder by the apportionment factor. The fractions of shares resulting from the application of the formula described above will not be considered, except insofar as it is necessary to ensure the materialization of the Offer for the total of the 16,390,172 shares offered to acquire, in which case such fractions will be considered for assign, among the accepting holders (including, for such purposes, the holders who have delivered their ADSs in acceptance), in decreasing order of magnitude of the fractions, the shares that are necessary to reach such number.

With respect to the holders of ADSs, considering that each ADS represents two shares in CCU, if the apportionment mechanism explained above results in a fraction or in an odd whole number of shares with respect to a holder of ADSs, then the number of shares with respect to that holder of ADSs will be rounded to an even whole number. The fractions and even whole numbers of shares resulting from the application of the described formula will not be considered, except insofar as it necessary to ensure the materialization of the Offer for the total of the 16,390,172 shares offered to acquire as indicated in the preceding paragraph.

Only those ADSs that, in accordance to the above, represent the shares accepted to purchase under the Offer will be delivered by the ADS Tender Agent to JPMorgan Chase Bank, NA, as depositary of the ADS under the ADS program of CCU, so that it cancel them and deliver the underlying shares to the account of the ADS Tender Agent with the US Settlement Agent (through its sub-custodian in Chile) so that the latter, in turn, delivers them to the Chilean Tender Agent for the settlement and payment of the offer. Those ADSs representing shares that,

due to the application of the apportionment factor described above, are not finally sold to the Offeror, will be returned to their holders as explained in Section 5.4 “Return of Securities” of this notice of commencement and as will be further explained in the US Offer Document.

3.4. Effective Term of the Offer

4.1. Price per share

The price to be paid for each CCU share will be Ch$6,800 (six thousand eight hundred pesos, national currency). For those who participate in the Chilean Offer or in the US Offer by offering shares to the U.S. Share Tender Agent, the price will be payable in pesos, national currency.

For those who participate in the US Offer offering ADSs that represent shares of CCU to the ADS Tender Agent, the price will also be payable in pesos, national currency. However, in this case, the Offeror has instructed the U.S. Settlement Agent to coordinate with Banco de Chile (the “FX Agent”) for the US dollars (“Dollars”) conversion of such pesos, upon instruction of the ADS Tender Agent and on the account of the ADSs holders who participate in the Offer in the United States of America and whose shares (underlying the ADS) are accepted in sale. To effect this exchange, the FX Agent and the U.S. Settlement Agent have agreed to arrange for the conversions of the pesos into Dollars at the exchange rate resulting from adding Ch$0.22 (twenty-two cents of peso, national currency) to the “dólar observado” exchange rate published by the Central Bank of Chile in the Official Gazette for the Payment Date (as defined below); provided, however, that such conversion may have to be executed at a different exchange rate in certain events further described in the U.S. Offer Document.

If the price per share of this Offer of Ch$6,800 is compared to the weighted average price of the stock transactions carried out between the ninetieth trading day and the thirtieth trading day prior to this date (which is equal to Ch$6,419.81), such premium amounts to approximately 5.92%. If the price per share of this Offer of Ch$6,800 is compared to the weighted average price of the stock transactions

carried out between the ninetieth trading day and the thirtieth trading day prior to this date, but deducting from such result the dividend of $139.16548 per share, announced by CCU on March 3, 2021 and paid to who were shareholders of CCU as of April 17 2021 (which is equal to $6,280.64), such premium amounts to 8.27%.

To those shareholders who sell their shares in Chile by virtue of acceptances given to the Chilean Tender Agent, by electronic transfer of immediately available funds in pesos, national currency, to the account that such shareholder had indicated in writing on or before the Expiration Date or by means of a nominative vale vista (bank check) that will remain at their disposal and may be withdrawn in the offices of the Chilean Tender Agent (located for these purposes at Agustinas No. 975, 2^nd Floor, borough and city of Santiago, Metropolitan region, Chile)during banking hours (Monday to Friday between 9:00 a.m. and 02:00 p.m. (Santiago, Chile time), except holidays);

To those shareholders who sell shares represented by ADSs by virtue of acceptances given to the ADS Tender Agent in the United States of America, the price will also be paid in pesos, national currency.

With respect to paragraph (ii) above, the term “Agent’s Message” means a message, transmitted by the Depository Trust Company (the “Account Entry Transfer Center”) to the ADSs Tender Agent and received by the latter, which is part of an account entry confirmation in which it is indicated that the Account Entry Transfer Center has received an express acknowledgment of receipt from the participant who offers the ADSs subject matter of said account entry confirmation, acknowledging that said participant has received and agrees to be bound by the terms of the ADSs Transmittal Letter, and that the Offeror may enforce said agreement against said participant.

The holders of ADSs should be aware that the Offer is only in respect of shares, and that by accepting the Offer in respect of the ADSs held by them, such holders will be authorizing the ADSs Tender Agent to instruct the U.S. Settlement Agent (acting through its sub-custodian in Chile) to communicate and transmit its acceptance to the Offer with respect to the shares underlying such ADSs to the Chilean Tender Agent, in order that, after the delivery of the Result Notice publication of the Result Ad, it instructs JPMorgan Chase Bank, NA, as depositary of the ADSs, to cancel them and deliver the underlying shares to be acquired by means of the Offer to the account of the ADS Tender Agent with the U.S. Settlement Agent (through its sub-custodian in Chile) for the latter, in turn, deliver them to the Chilean Tender Agent for the settlement and payment of the Offer.

Direct participation in the Offer as a shareholder. As an alternative to offering shares represented by ADSs for sale through the ADSs Tender Agent, a holder of ADSs can also deliver them to JPMorgan Chase Bank, NA, as depositary of the ADSs, have them canceled, and withdraw the CCU shares underlying the ADSs of the ADSs program, and then directly participate in the Offer as a shareholder, either by delivering its shares to the US Tender Agent as indicated in the first paragraph of this Section 5.3, or by instructing a local intermediary to offer them for sale in the Offer or by delivering the shares directly to the Chilean Tender Agent in Chile together with the documents listed in Section 5.2 (“Formalities and documents necessary for the acceptance of the Offer in Chile”) of this notice of commencement.

To withdraw the CCU shares underlying the ADSs from the ADS program, such holder must cancel them by: (i) delivering to the ADSs representing the shares the holder wish to offer for sale to JPMorgan Chase Bank, N.A., as depositary of ADSs, at the corresponding address according to the deposit agreement entered into between JP Morgan Chase Bank, N.A. and CCU on July 13, 2013; (ii) paying a commission to the depositary of ADSs of US$ 0.05 for each ADS; and (iii) paying any tax or charge due in connection with the withdrawal of the shares from the ADSs program, and complying with any other terms and conditions of the deposit agreement between JP Morgan Chase Bank, N.A. and CCU described above.

In any case, the ADS Tender Agent will give notice to the U.S. Settlement Agent of the acceptances it receives of the Offer, and will instruct it to deliver them (either directly or through its sub-custodian in Chile) to the Chilean Tender Agent, by submitting an acceptance letter of the Offer to the Chilean Tender Agent, regarding the shares represented by ADSs whose acceptances have been delivered to the ADSs Tender Agent. Finally, the Chilean Tender Agent will proceed to the settlement and payment of the Offer as indicated in Sections 4.3 and 5.2 of this notice of commencement.
