Delivery of this Letter of Transmittal to an address other than as set forth above will not constitute a valid delivery to Broadridge Corporate Issuer Solutions, LLC (the “Depositary and Paying Agent”). You must sign this Letter of Transmittal in the appropriate space provided therefor below, with signature guaranteed, if required, and complete and sign the Internal Revenue Service (the “IRS”) Form W-9 included in this Letter of Transmittal, if the stockholder is a U.S. person. Stockholders who are not U.S. persons should submit a properly completed and signed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or other appropriate IRS Form W-8. Failure to provide the information on IRS Form W-9 or an appropriate IRS Form W-8, as applicable, may subject you to U.S. backup withholding on any payments made to you pursuant to the Offer (as defined below). The instructions set forth in this Letter of Transmittal should be read carefully before you tender any of your Shares (as defined below) into the Offer (as defined below).

The Offer is being made to all holders of the Shares. Purchaser is not aware of any jurisdiction in which the making of the Offer or the acceptance thereof would be prohibited by securities, “blue sky” or other valid laws or regulations of such jurisdiction. If Purchaser becomes aware of any U.S. state in which the making of the Offer or the acceptance of Shares pursuant thereto would not be in compliance with an administrative or judicial action taken pursuant to a U.S. state statute, Purchaser will make a good faith effort to comply with any such law or regulation. If, after such good faith effort, Purchaser cannot comply with any such law or regulation, the Offer will not be made to (nor will tenders be accepted from or on behalf of) the holders of Shares in such state. In any jurisdictions where applicable laws or regulations require the Offer to be made by a licensed broker or dealer, the Offer shall be deemed to be made on behalf of Purchaser by one or more registered brokers or dealers licensed under the laws or regulations of such jurisdiction to be designated by Purchaser.

This Letter of Transmittal is to be used by stockholders of Kronos Bio, Inc. (“Kronos”) if certificates (“Certificates”) for shares of common stock, par value $0.001 per share, of Kronos (the “Shares”) are to be forwarded herewith.

The undersigned hereby tenders to Concentra Merger Sub IV, Inc., a Delaware corporation (“Purchaser”) and a wholly owned subsidiary of Concentra Biosciences, LLC, a Delaware limited liability company (“Parent”), the above described shares of common stock, par value $0.001 per share (the “Shares”), of Kronos Bio, Inc., a Delaware corporation (“Kronos”), pursuant to Purchaser’s offer to purchase each outstanding Share that is validly tendered and not properly withdrawn, for: (i) $0.57 per Share in cash (the “Cash Amount”); and (ii) one non-transferable contractual contingent value right for each Share (each, a “CVR,” and each CVR together with the Cash Amount, the “Offer Price”), subject to the terms and conditions described in the Offer to Purchase, dated May 15, 2025 (together with any amendments or supplements thereto, the “Offer to Purchase”) and in this Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal” which, together with the Offer to Purchase, as each may be amended and supplemented from time to time, collectively constitute the “Offer”), receipt of which is hereby acknowledged.

Upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of any such extension or amendment), and effective upon acceptance for payment of the Shares validly tendered herewith and not properly withdrawn on or prior to the Expiration Date in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to or upon the order of Purchaser all right, title and interest in and to all of the Shares that are being tendered hereby (and any and all dividends, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after the date hereof (collectively, “Distributions”)) and irrevocably constitutes and appoints Broadridge Corporate Issuer Solutions, LLC (the “Depositary and Paying Agent”) the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and any and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest in the Shares tendered by this Letter of Transmittal), to: (i) deliver Certificates for such Shares (and any and all Distributions) or transfer ownership of such Shares (and any and all Distributions) on the account books maintained by The Depository Trust Company (“DTC”) or otherwise held in book-entry form, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser; (ii) present such Shares (and any and all Distributions) for transfer on the books of Kronos; and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any and all Distributions), all in accordance with the terms and subject to the conditions of the Offer.

By executing this Letter of Transmittal, the undersigned hereby irrevocably appoints Kevin Tang, the designee of Purchaser, the attorney-in-fact and proxy of the undersigned, with full power of substitution, to: (i) vote at any annual or special meeting of Kronos stockholders or any adjournment or postponement thereof or otherwise in such manner as such attorney-in-fact and proxy or his substitute shall in his, her or its sole discretion deem proper with respect to; (ii) execute any written consent concerning any matter as such attorney-in-fact and proxy or his substitute shall in his, her or its sole discretion deem proper with respect to; and (iii) otherwise act as such attorney-in-fact and proxy or his substitute shall in his, her or its sole discretion deem proper with respect to, all of the Shares (and any and all Distributions) tendered hereby and accepted for payment by Purchaser. This appointment will be effective if and when, and only to the extent that, Purchaser accepts such Shares tendered with this Letter of Transmittal for payment pursuant to the Offer. This power of attorney and proxy are irrevocable and are granted in consideration of the acceptance for payment of such Shares in accordance with the terms of the Offer. Such acceptance for payment shall, without further action, revoke any prior powers of attorney and proxies granted by the undersigned at any time with respect to such Shares (and any and all Distributions), and no subsequent powers of attorney, proxies, consents or revocations may be given by the undersigned with respect thereto (and, if given, will not be deemed effective). Purchaser reserves the right to require that, in order for the Shares to be deemed validly tendered, immediately upon Purchaser’s acceptance for payment of such Shares, Purchaser or its designees must be able to exercise full voting, consent and other rights with respect to such Shares (and any and all Distributions), including voting at any meeting of Kronos stockholders or executing a written consent concerning any matter.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer any and all of the Shares tendered hereby (and any and all Distributions) and that, when the same are accepted for payment by Purchaser, Purchaser will acquire good, marketable and unencumbered title to such Shares (and such Distributions), free and clear of all liens, restrictions, charges and encumbrances and the same will not be subject to any adverse claims. The undersigned hereby represents and warrants that the

undersigned is the registered owner of the Shares. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary and Paying Agent or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby (and any and all Distributions). In addition, the undersigned shall remit and transfer promptly to the Depositary and Paying Agent for the account of Purchaser all Distributions in respect of any and all of the Shares tendered hereby, and, pending such remittance and transfer or appropriate assurance thereof, Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire Offer Price of the Shares tendered hereby or deduct from such Offer Price the amount or value of such Distribution as determined by Purchaser in its sole discretion.

All authority conferred or agreed to be conferred pursuant to this Letter of Transmittal shall not be affected by, and shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, successors and assigns of the undersigned. Except as stated in the Offer to Purchase, this tender is irrevocable.

It is understood that the undersigned will not receive payment for the Shares unless and until the Shares are accepted for payment and until the Certificate(s) owned by the undersigned are received by the Depositary and Paying Agent at the address set forth above, together with such additional documents as the Depositary and Paying Agent may require, and until the same are processed for payment by the Depositary and Paying Agent.

The undersigned hereby acknowledges that delivery of any Certificate shall be effected, and risk of loss and title to such Certificate shall pass, only upon the proper delivery of such Certificate to the Depositary and Paying Agent.

The undersigned understands that the valid tender of Shares pursuant to any of the procedures described in the Offer to Purchase and in the instructions hereto will constitute the undersigned’s acceptance of the terms and conditions of the Offer. Purchaser’s acceptance of such Shares for payment will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms and conditions of such extension or amendment). The undersigned recognizes that under certain circumstances set forth in the Offer, Purchaser may not be required to accept for payment any Shares tendered hereby.

The undersigned understands that the CVRs will not be transferable except: (a) upon death of the holder by will or intestacy; (b) pursuant to a court order; (c) by operation of law (including by consolidation or merger) or without consideration in connection with the dissolution, liquidation or termination of any corporation, limited liability company, partnership or other entity; (d) in the case of CVRs held in book-entry or other similar nominee form, from a nominee to a beneficial owner and, if applicable, through an intermediary, to the extent allowable by the Depository Trust Company (“DTC”)); or (e) that CVRs may be abandoned by transferring such CVR to Purchaser or Parent without consideration therefor. The undersigned further understands that the CVRs will not have any voting or dividend rights, or accrue interest and will not represent any equity or ownership interests in the Purchaser, Parent or Kronos. The undersigned understands that the CVRs will be registered in the name of the undersigned.

Unless otherwise indicated under “Special Payment Instructions,” a check will be issued for the Cash Amount of all Shares purchased and, if appropriate, Certificates not tendered or accepted for payment in the name(s) of the registered holder(s) appearing above under “Description of Shares Tendered” will be returned. Similarly, unless otherwise indicated under “Special Delivery Instructions,” the check for the Cash Amount of all Shares purchased will be mailed and, if appropriate, any Certificates not tendered or not accepted for payment (and any accompanying documents, as appropriate) will be returned to the address(es) of the registered holder(s) appearing above under “Description of Shares Tendered.” In the event that the boxes entitled “Special Payment Instructions” and “Special Delivery Instructions” are both completed, the check for the Cash Amount of all Shares purchased will be issued and, if appropriate, any Certificates not tendered or not accepted for payment (and any accompanying documents, as appropriate) will be returned in the name(s) of, and deliver such check and, if appropriate, return any Certificates (and any accompanying documents, as appropriate) to, the person(s) so indicated. The undersigned recognizes that Purchaser has no obligation, pursuant to the “Special Payment Instructions,” to transfer any Shares from the name of the registered holder thereof if Purchaser does not accept for payment any of the Shares so tendered. Subject to the terms of the CVR Agreement, please make all payments regarding the CVRs as directed herein for payment of the cash consideration and enter in the CVR register to be maintained by the rights agent pursuant to the CVR Agreement the name(s) and address(es)

appearing on the cover page of this Letter of Transmittal for each registered holder.

The method of delivery of Shares, Certificate(s), this Letter of Transmittal, and all other required documents, is at the election and risk of the tendering stockholder. Shares will be deemed delivered (and the risk of loss of Certificates will pass) only when actually received by the Depositary and Paying Agent.

No fractional Shares will be purchased. By executing this Letter of Transmittal, the tendering stockholder waives any right to receive any notice of the acceptance for payment of Shares.

3. INADEQUATE SPACE. If the space provided herein is inadequate, Certificate numbers, the number of Shares represented by such Certificates and/or the number of Shares tendered should be listed on a separate signed schedule attached hereto.

4. PARTIAL TENDERS (NOT APPLICABLE TO STOCKHOLDERS WHO TENDER BY BOOK-ENTRY TRANSFER). If fewer than all the Shares represented by any Certificate delivered to the Depositary and Paying Agent are to be tendered, fill in the number of Shares which are to be tendered in the box entitled “Total Number of Shares Tendered.” In such case, a new Certificate for the remainder of the Shares represented by the old Certificate will be sent to the person(s) signing this Letter of Transmittal, unless otherwise provided in the appropriate box on this Letter of Transmittal, as promptly as practicable following the expiration or termination of the Offer.

6. STOCK TRANSFER TAXES.

If, however, consideration is to be paid to, or if Certificate(s) for Shares not tendered or not accepted for payment are to be registered in the name of, any person(s) other than the registered holder(s), or if tendered Certificate(s) for Share(s) are registered in the name of any person(s) other than the person(s) signing this Letter of Transmittal, Purchaser or any successor entity thereto will not be responsible for any stock transfer or similar taxes (whether imposed on the registered holder(s) or such other person(s) or otherwise) payable on account of the transfer to such other person(s) and no consideration shall be paid in respect of such Share(s) unless evidence satisfactory to Purchaser or any successor entity thereto of the payment of such taxes, or the inapplicability of such taxes, is submitted.

7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.

8. TAX WITHHOLDING. Under U.S. federal income tax laws, the Depositary and Paying Agent may be required to withhold a portion of any payments made to certain stockholders pursuant to the Offer. To avoid such backup withholding, a tendering stockholder that is a U.S. person (as defined for in the instructions to IRS Form W-9, a “U.S. person”), and, if applicable, each other U.S. payee, is required to: (a) provide the Depositary and Paying Agent with a correct Taxpayer Identification Number (“TIN”) on IRS Form W-9, which is included herein, and to certify, under penalty of perjury, that such number is correct and that such stockholder or payee is not subject to backup withholding of U.S. federal income tax; or (b) otherwise establish a basis for exemption from backup withholding. Failure to provide the information on the IRS Form W-9 may subject the tendering stockholder or payee to backup withholding at the then applicable rate (currently 24%), and such stockholder or payee may be subject to a penalty imposed by the IRS. See the enclosed IRS Form W-9 and the instructions thereto for additional information.

Certain stockholders or payees (including, among others, corporations) may not be subject to backup withholding. Exempt stockholders or payees that are U.S. persons should furnish their TIN, check the appropriate box on the IRS Form W-9 and sign, date and return the IRS Form W-9 to the Depositary and Paying Agent in order to avoid backup withholding. A stockholder or other payee that is not a U.S. person can establish an exemption from backup withholding: (a) by providing the Depositary and Paying Agent with a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or other appropriate IRS Form W-8, signed under penalties of perjury, attesting to such stockholder’s or payee’s foreign status; or (b) by otherwise establishing an exemption. An appropriate IRS Form W-8 may be obtained from the Depositary and Paying Agent or the IRS website (www.irs.gov). The Depositary and Paying Agent may withhold tax at a 30% rate (subject to certain exceptions) on payments made to non-U.S. stockholders pursuant to the Offer, unless the Depositary and Paying Agent determines that a reduced rate under an applicable income tax treaty or exemption from withholding is applicable. See “The Tender Offer—Section 3. Procedures for Tendering Shares” and “Special Factors—Section 6. Material U.S. Federal Income Tax Consequences of the Offer and the Merger” of the Offer to Purchase.

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund or credit may be obtained from the IRS if eligibility is established and appropriate procedure is followed. Stockholders are urged to consult their tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the IRS refund procedure.

9. IRREGULARITIES. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by the Depositary and Paying Agent, in its sole discretion, which determination shall be final and binding on all parties. Purchaser reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance for payment of which may, in the opinion of its counsel, be unlawful. Purchaser also reserves the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been waived or cured within such time as Purchaser shall determine. None of Parent, Purchaser, the Depositary and Paying Agent, the Information Agent or any other person will be under any duty to give notice of any defects or irregularities in tenders or incur any liability for failure to give any such notice. Purchaser’s interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and the instructions thereto) will be final and binding.

10. QUESTIONS AND REQUESTS FOR ADDITIONAL COPIES. The Information Agent may be contacted at the address and telephone number set forth on the last page of this Letter of Transmittal for questions and/or requests for additional copies of the Offer to Purchase, this Letter of Transmittal and other tender offer materials. You may also contact your broker, dealer, commercial bank, trust company or other nominee for assistance. Such copies will be furnished promptly at Purchaser’s expense.

11. LOST, STOLEN DESTROYED OR MUTILATED CERTIFICATES. If any Certificate has been lost, stolen, destroyed or mutilated, the stockholder should promptly notify the Transfer Agent toll-free at 1-800-937-5449. The stockholder will then be instructed as to the steps that must be taken in order to replace such Certificates. You may be required to post a bond to secure against the risk that the Certificate(s) may be subsequently recirculated. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed or stolen certificates have been followed. You are urged to contact the Transfer Agent immediately in order to receive further instructions and for a determination of whether you will need to post a bond and to permit timely processing of this documentation. This Letter of Transmittal and related documents cannot be processed until the procedures for replacing lost, destroyed, mutilated or stolen Certificates have been followed.

Certificates evidencing tendered Shares, as well as this Letter of Transmittal, properly completed and duly executed, with any required signature guarantees, and any other documents required by this Letter of Transmittal, must be received before the Expiration Date.

Under federal income tax law, a stockholder who is a U.S. person (as defined in the instructions to IRS Form W-9) surrendering Shares must, unless an exemption applies, provide the Depositary (as payer) with the stockholder’s correct TIN on IRS Form W-9, a copy of which is included in this Letter of Transmittal. If the stockholder is an individual, then the stockholder’s TIN is generally such stockholder’s Social Security number. If the correct TIN is not provided, then the stockholder may be subject to a penalty imposed by the IRS and payments of cash to the stockholder (or other payee) pursuant to the Offer may be subject to U.S. federal backup withholding at the then applicable rate (currently imposed at a rate of 24%).

Certain stockholders (including, among others, certain corporations and certain foreign individuals and entities) may not be subject to backup withholding and reporting requirements. In order for an exempt stockholder who is not a U.S. person (as defined in the instructions to IRS Form W-9) to avoid backup withholding, such person should complete, sign and submit an appropriate IRS Form W-8 signed under penalties of perjury, attesting to his, her or its exempt status. IRS Forms W-8 can be obtained from the Depositary, or from the IRS website at: http://www.irs.gov/w8. Such stockholders should consult a tax advisor to determine which version of IRS Form W-8 is appropriate. Exempt stockholders who are U.S. persons should furnish their TIN, check the “Exempt payee” box on the IRS Form W-9 and sign, date and return the IRS Form W-9 to the Depositary in order to avoid erroneous backup withholding. See the instructions enclosed with the IRS Form W-9 included in this Letter of Transmittal for additional instructions.

If backup withholding applies, the Depositary is required to withhold and pay over to the IRS a portion of any payment made to a stockholder. Backup withholding is not an additional tax. Rather, the federal income tax liability of persons subject to backup withholding may be reduced by the amount of tax withheld provided the required information is timely provided to the IRS. If backup withholding results in an overpayment of taxes, a refund may be obtained from the IRS provided the required information is timely provided to the IRS.

EACH STOCKHOLDER IS URGED TO CONSULT WITH HIS, HER OR ITS TAX ADVISOR REGARDING THE TAX CONSEQUENCES OF THE TRANSACTION IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

To prevent backup withholding on payments that are made to a stockholder with respect to Shares purchased pursuant to the Offer, the stockholder is required to notify the Depositary of the stockholder’s correct TIN by completing the IRS Form W-9 included in this Letter of Transmittal certifying that (1) the TIN provided on the IRS Form W-9 is correct (or that such stockholder is awaiting a TIN), (2) the stockholder is not subject to backup withholding because (i) the stockholder is exempt from backup withholding, (ii) the stockholder has not been notified by the IRS that the stockholder is subject to backup withholding as a result of a failure to report all interest and dividends or (iii) the IRS has notified the stockholder that the stockholder is no longer subject to backup withholding, and (3) the stockholder is a U.S. person (as defined in the instructions to IRS Form W-9).

The tendering stockholder is required to give the Depositary the TIN, generally the Social Security number or employer identification number, of the record holder of all Shares tendered hereby. If such Shares are in more than one name or are not in the name of the actual owner, consult the instructions enclosed with the IRS Form W-9 included in this Letter of Transmittal for additional guidance on which number to report. If the tendering stockholder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, such stockholder should write “Applied For” in the space for the TIN on the IRS Form W-9, sign and date the IRS Form W-9 and sign and date the Certificate of Awaiting Taxpayer Identification Number below. If the tendering stockholder writes “Applied For” in the space for the TIN and the Depositary is not provided with a TIN by the time of payment, the Depositary will withhold a portion of all payments of the purchase price, which will be refunded if a TIN is provided to the Depositary within sixty days of the Depositary’s receipt of the Certificate of Awaiting Taxpayer Identification Number. If the Depositary is provided with an incorrect TIN in connection with such payments, then the stockholder may be subject to a penalty imposed by the IRS.

NOTE: FAILURE TO COMPLETE AND RETURN THE IRS FORM W-9 INCLUDED IN THIS LETTER OF TRANSMITTAL MAY RESULT IN BACKUP WITHHOLDING OF A PORTION OF ANY PAYMENTS

MADE TO YOU PURSUANT TO THE OFFER. PLEASE REVIEW THE INSTRUCTIONS ENCLOSED WITH THE IRS FORM W-9 INCLUDED IN THIS LETTER OF TRANSMITTAL FOR ADDITIONAL DETAILS. YOU MUST COMPLETE THE FOLLOWING CERTIFICATE IF YOU WROTE “APPLIED FOR” IN THE SPACE FOR THE TIN ON THE IRS FORM W-9.
