The undersigned understands that the acceptance for payment by Tether of Shares tendered pursuant to one of the procedures described in Section 2 of the Offer to Purchase and in the instructions hereto will constitute a binding agreement between the undersigned and Tether upon the terms and subject to the conditions of the Offer, which agreement will be governed by, and construed in accordance with, the laws of the State of New York.

The undersigned understands that all Shares properly tendered and not properly withdrawn will be purchased at the Purchase Price, less any applicable withholding taxes and without interest, upon the terms and subject to the conditions of the Offer, including the proration provisions as described in the Offer to Purchase.

Guarantee of Signatures.   Except as otherwise provided below, all signatures on this Letter of Transmittal must be guaranteed by a financial institution (including most commercial banks, savings and loan associations and brokerage houses) that is a member in good standing of a recognized Medallion Program approved by the Securities Transfer Association, Inc., including the (i) Security Transfer Agents Medallion Program, (ii) the New York Stock Exchange Medallion Signature Program and (iii) the Stock Exchanges Medallion Program (each, an “Eligible Institution”). Signatures on this Letter of Transmittal need not be guaranteed (a) if this Letter of Transmittal is signed by the registered holder(s) (which term, for purposes of this document, includes any shareholder registered on the books of the Company’s transfer agent) of Shares tendered herewith and such registered holder has not completed the box titled “Special Payment Instructions” or the box titled “Special Delivery Instructions” on this Letter of Transmittal or (b) if such Shares are tendered for the account of an Eligible Institution. See Instruction 5.

2. Delivery of Letter of Transmittal and Certificates or Book-Entry Confirmations.   This Letter of Transmittal is to be completed by registered shareholders if Share Certificates are to be forwarded herewith. If tenders are to be made pursuant to the procedures for tender by book-entry transfer set forth in Section 3 of the Offer to Purchase, an Agent’s Message must be utilized. Share Certificates representing all physically tendered Shares, or confirmation of any book-entry transfer into the Depositary’s account at DTC of Shares tendered by book-entry transfer (“Book-Entry Confirmation”), as well as this Letter of Transmittal properly completed and duly executed with any required signature guarantees, or an Agent’s Message in the case of a book-entry transfer, and any other documents required by this Letter of Transmittal, must be received by the Depositary at its address set forth herein prior to the Expiration Time. Please do not send your Share Certificates directly to Tether.

A properly completed and duly executed Letter of Transmittal must accompany each such delivery of Share Certificates to the Depositary.

The term “Agent’s Message” means a message transmitted by the book-entry transfer facility to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, stating that the book-entry transfer facility has received an express acknowledgment from the participant tendering Shares through the book-entry transfer facility that the participant has received and agrees to be bound by the terms of this Letter of Transmittal and that Tether may enforce that agreement against that participant.

THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC, IS AT THE SOLE ELECTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF YOU PLAN TO MAKE DELIVERY BY MAIL, IT IS RECOMMENDED THAT YOU DELIVER BY REGISTERED MAIL WITH RETURN RECEIPT REQUESTED AND OBTAIN PROPER INSURANCE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

LETTERS OF TRANSMITTAL MUST BE RECEIVED IN THE OFFICE OF THE DEPOSITARY BY THE EXPIRATION TIME. DELIVERY OF THESE DOCUMENTS TO THE DEPOSITARY’S P.O. BOX ON APRIL 24, 2025 DOES NOT CONSTITUTE RECEIPT BY THE DEPOSITARY. TIMELINESS OF RECEIPT OF ALL DOCUMENTS SHALL BE DETERMINED BY THE DEPOSITARY IN ITS SOLE DISCRETION.

No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be purchased. All tendering shareholders, by execution of this Letter of Transmittal, waive any right to receive any notice of the acceptance of their Shares for payment.

All questions as to the number of Shares to be accepted, the price to be paid for Shares and the validity, form, eligibility (including time of receipt) and acceptance for payment of any Shares will be determined by Tether, in its sole discretion, and its determination will be final and binding on all parties, subject to an Offer participant’s right to dispute such determination in a court of competent jurisdiction. Tether reserves the absolute right to reject any or all tenders it determines not to be in proper form or the

acceptance for payment of or payment for which may, in the opinion of the Tether’s counsel, be unlawful. Tether also reserves the absolute right to waive any conditions of the Offer with respect to all shareholders or any defect or irregularity in any tender with respect to any particular Shares or any particular shareholder whether or not Tether waives similar defects or irregularities in the case of other shareholders. No tender of Shares will be deemed to have been properly made until all defects or irregularities relating thereto have been cured or waived. None of Tether, the Company, the Depositary or the Information Agent will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Tether’s interpretation of the terms of and conditions to the Offer, including this Letter of Transmittal and the instructions thereto, will be final and binding on all parties, subject to an Offer participant’s right to dispute such determination in a court of competent jurisdiction.

3. Inadequate Space.   If the space provided herein is inadequate, the certificate numbers and/or the number of Shares should be listed on a separate schedule attached hereto and separately signed on each page thereof in the same manner as this Letter of Transmittal is signed.

4. Partial Tenders (Applicable to Certificate Shareholders Only).   If fewer than all the Shares evidenced by any Share Certificate delivered to the Depositary are to be tendered, fill in the number of Shares which are to be tendered in the column titled “Number of Shares Tendered” in the box titled “Description of Shares Surrendered.” In such cases, new book entry shares for the remainder of the Shares that were evidenced by the old certificate(s) but not tendered will be credited to the registered holder, unless otherwise provided in the appropriate box on this Letter of Transmittal, as soon as practicable after the Expiration Time. All Shares represented by Share Certificates delivered to the Depositary will be deemed to have been tendered unless otherwise indicated.

5. Signatures on Letter of Transmittal; Stock Powers and Endorsements.   If this Letter of Transmittal is signed by the registered holder(s) of the Shares tendered hereby, the signature(s) must correspond with the name(s) as written on the face of the Share Certificate(s) without alteration or any other change whatsoever.

If any Shares tendered hereby are owned of record by two or more joint owners, all such persons must sign this Letter of Transmittal.

If any tendered Shares are registered in the names of different holder(s), it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles thereof) as there are different registrations of such Shares.

If this Letter of Transmittal or any certificates or stock powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing, and proper evidence satisfactory to Tether of their authority so to act must be submitted.

If this Letter of Transmittal is signed by the registered holder(s) of the Shares listed and transmitted hereby, no endorsements of Share Certificates or separate stock powers are required unless payment is to be made to, or Share Certificates representing Shares not tendered or accepted for payment are to be issued in the name of, a person other than the registered holder(s), in which case the Share Certificates representing the Shares tendered by this Letter of Transmittal must be endorsed or accompanied by appropriate stock powers, in either case, signed exactly as the name(s) of the registered holder(s) appear(s) on the Share Certificates. Signatures on such Share Certificates or stock powers must be guaranteed by an Eligible Institution.

If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Share(s) listed, the Share Certificate(s) must be endorsed or accompanied by the appropriate stock powers, in either case, signed exactly as the name or names of the registered holder(s) appear(s) on the Share Certificate(s). Signatures on such Share Certificates or stock powers must be guaranteed by an Eligible Institution.

6. Transfer Taxes.   Tether will pay all stock transfer taxes, if any, payable on the transfer to Tether of Shares purchased pursuant to the Offer (for the avoidance of doubt, transfer taxes do not include United States federal income or backup withholding taxes). If, however, payment of the Purchase Price is to be made to, or (in the circumstances permitted by the Offer) if unpurchased Shares are to be registered in the name

of, any person other than the registered holder, or if tendered certificates are registered in the name of any person other than the person signing this Letter of Transmittal, the amount of all stock transfer taxes, if any (whether imposed on the registered holder or the other person), payable on account of the transfer to the person will be deducted from the Purchase Price unless satisfactory evidence of the payment of the stock transfer taxes, or exemption from payment of the stock transfer taxes, is submitted.

Except as provided in this Instruction 6, it will not be necessary for transfer tax stamps to be affixed to the Share Certificates listed in this Letter of Transmittal.

7. Special Payment and Delivery Instructions.   If a check for the Purchase Price is to be issued, and/or Share Certificates representing Shares not tendered or accepted for payment are to be issued or returned to, a person other than the signer(s) of this Letter of Transmittal or to an address other than that shown in the box titled “Description of Shares Surrendered” above, the appropriate boxes on this Letter of Transmittal should be completed. Shareholders delivering Shares tendered hereby or by Agent’s Message by book-entry transfer may request that Shares not purchased be credited to an account maintained at DTC as such shareholder may designate in the box titled “Special Payment Instructions” herein. If no such instructions are given, all such Shares not purchased will be returned by crediting the same account at DTC as the account from which such Shares were delivered.

8. Requests for Assistance or Additional Copies.   Questions or requests for assistance may be directed to the Information Agent at the address and telephone number set forth below or to your broker, dealer, commercial bank or trust company. Additional copies of the Offer to Purchase, this Letter of Transmittal and other tender offer materials may be obtained from the Information Agent as set forth below, and will be furnished at Tether’s expense.

9. Tax Identification Number and Backup Withholding.   For additional information on applicable withholding tax, see Section 3 of the Offer to Purchase. To prevent backup withholding, each U.S. Holder (as defined below) should either (x) provide his, her or its correct taxpayer identification number (“TIN”) by completing the copy of the Substitute Form W-9 (the “Form W-9”) attached to this Letter of Transmittal, certifying that (1) he, she or it is a “United States person” ​(as defined in section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), (2) the TIN provided is correct (or that such U.S. Holder is awaiting a TIN) and (3) that the U.S. Holder is not subject to backup withholding because (i) the holder is exempt from backup withholding, (ii) the holder has not been notified by the Internal Revenue Service (the “IRS”) that he, she or it is subject to backup withholding as a result of a failure to report all interest or dividends or (iii) the IRS has notified the U.S. Holder that he, she or it is no longer subject to backup withholding, or (y) otherwise establish an exemption. If you do not provide the Depositary (or other applicable withholding agent) with the correct TIN or an adequate basis for exemption, you may be subject to a $50 penalty imposed by the IRS, and payments made to you pursuant to the Offer may be subject to backup withholding at a rate of 24%. If withholding results in an overpayment of taxes, a refund may be obtained, provided the required information is timely furnished to the IRS. Backup withholding is not an additional tax. Taxpayers may use amounts withheld as a credit against their U.S. federal income tax liability or claim a refund of such amounts if they timely provide certain required information to the IRS.

To prevent backup withholding, a Non-U.S. Holder (as defined below) should (i) submit a properly completed IRS Form W-8BEN or W-8BEN-E, as appropriate (or other applicable IRS Form W-8), to the Depositary (or other applicable withholding agent), certifying under penalties of perjury to the holder’s exempt status or (ii) otherwise establish an exemption. IRS Forms W-8BEN and W-8BEN-E (and other applicable IRS Forms W-8) may be obtained from the Depositary or on the web at www.irs.gov. Certain holders (including, among others, corporations) and certain Non-U.S. Holders are exempt recipients generally not subject to these backup withholding requirements. Exempt recipients that are U.S. Holders should refer to the enclosed Form W-9 for additional information regarding exempt recipients. To avoid possible erroneous backup withholding, exempt U.S. Holders, while not required to file Form W-9, should complete and return the Form W-9 and provide their proper “Exempt payee code” on its face. In order for a Non-U.S. Holder (as defined below) to qualify as an exempt recipient, that shareholder must submit an IRS Form W-8BEN or W-8BEN-E (or other applicable IRS Form W-8), signed under penalties of perjury, attesting to that shareholder’s non-U.S. status. The applicable form can be obtained from the Depositary or on the web at www.irs.gov.

For the purposes of these instructions, a “U.S. Holder” is (i) an individual who is a citizen or resident alien of the United States, (ii) a corporation (including an entity taxable as a corporation) created under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income tax regardless of its source or (iv) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person. Holders that are, or hold their Shares through, partnerships and other pass-through entities should consult their tax advisors regarding their treatment for purposes of these instructions. A “Non-U.S. Holder” is any holder (other than a holder that is, or holds its Shares through, a partnership or other pass-through entity) that is not a U.S. Holder. See the enclosed Form W-9 for additional information and instructions.

HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF U.S. FEDERAL INCOME TAX WITHHOLDING AND BACKUP WITHHOLDING, INCLUDING THE COMPLETION OF IRS FORM W-9, IRS FORM W-8BEN OR OTHER APPROPRIATE IRS FORM W-8. ELIGIBILITY FOR A WITHHOLDING TAX REDUCTION OR EXEMPTION, AND THE REFUND PROCEDURE.

10. Waiver of Conditions.   Subject to the terms and conditions of the Transaction Agreement (as defined in the Offer to Purchase) and the applicable rules and regulations of the Securities and Exchange Commission, the conditions of the Offer may be waived by Tether in whole or in part at any time and from time to time in its sole discretion, subject to certain conditions that may be waived only with the consent of the Company.

IMPORTANT: THIS LETTER OF TRANSMITTAL OR AN AGENT’S MESSAGE, TOGETHER WITH SHARE CERTIFICATE(S) OR BOOK-ENTRY CONFIRMATION AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION TIME.

NOTE: FAILURE TO COMPLETE AND RETURN THIS FORM MAY RESULT IN BACKUP WITHHOLDING OF A PORTION OF ANY PAYMENT MADE TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE ENCLOSED GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 FOR ADDITIONAL DETAILS.

12. Lost, Destroyed or Stolen Certificates.   If any certificate representing Shares has been lost, destroyed or stolen, the shareholder should promptly notify the transfer agent for Adecoagro common shares, Computershare Trust Company, N.A., at 800 522 6645. The shareholder will then be instructed as to the steps that must be taken in order to replace such certificate. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost or destroyed certificates have been completed.

IMPORTANT TAX INFORMATION

Under current U.S. federal income tax law, a U.S. Holder who tenders Adecoagro stock certificates that are accepted for exchange may be subject to backup withholding. In order to avoid such backup withholding, such shareholder must provide the Depositary with such shareholder’s correct taxpayer identification number and certify that such shareholder is not subject to such backup withholding by completing Substitute Form W-9 (“Form W-9”) provided herewith. In general, if a shareholder is an individual, the taxpayer identification number is the Social Security number of such individual. If the Depositary is not provided with the correct taxpayer identification number, the shareholder may be subject to a $50 penalty imposed by the Internal Revenue Service (the “IRS”). For further information concerning backup withholding and instructions for completing Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete Form W-9 if the Adecoagro stock certificates are held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Form W-9.

Certain shareholders (including, among others, all domestic corporations and certain Non-U.S. Holders) are not subject to these backup withholding and reporting requirements. In order to satisfy the Depositary that a foreign individual qualifies as an exempt recipient, such shareholder must submit a statement, signed under penalties of perjury, attesting to that individual’s exempt status, on a properly completed Form W-8BEN, Form W-8BEN-E, or other applicable IRS Form or successor form. Such statements can be obtained from the Depositary or on the web at www.irs.gov.

Failure to complete Form W-9 or appropriate Form W-8, as applicable, will not, by itself, cause Adecoagro stock certificates to be deemed invalidly tendered, but may require the Depositary to withhold a portion of the amount of any payments made pursuant to the Offer. Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is furnished to the IRS.

Privacy Act Notice. — Section 6109 requires most recipients of dividend, interest, or certain other income to give taxpayer identification numbers to payers who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of tax returns. The IRS may also provide this information to the Department of Justice for civil and criminal litigation and to cities, states and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold a portion of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties
