This Agreement (the “Agreement”) confirms the agreement between Simon Khalaf (“you”) and Marqeta, Inc. (the “Company”) (jointly referred to as the “Parties” or individually referred to as a “Party”) regarding the separation of your employment with the Company. You will have until March 17, 2025 to execute this Agreement and receive the Severance Benefits described below.

B. As of February 24, 2025 (the “Transition Date”), you resigned as the Company’s Chief Executive Officer and a member of the Company’s board of directors (the “Board”), and from any other officer or director positions you occupied with the Company or any subsidiary or affiliate of the Company immediately prior to the Transition Date.

C. The Parties wish by this Agreement to fully and finally resolve, settle, and compromise any and all issues, disputes, differences, claims, and/or liabilities arising out of or relating to your employment with the Company.

1. Consideration. You acknowledge that you will only receive the consideration provided in this Section 1 if you (i) return all Company property on or before the Effective Date (as defined below); and (ii) have signed this Agreement. Contingent upon your compliance with (i)-(ii) in the foregoing sentence, the Company agrees to provide you with the following consideration: (i) a single lump payment in an amount equal to twelve (12) months of your base salary (which amount is $600,000), plus one hundred (100%) of your annual target bonus in effect as of the Separation Date (which amount is $600,000), for a total payment of $1,200,000, less all applicable withholdings and (ii) reimburse you for the payments you make for COBRA coverage for you and your covered dependents as of the Separation Date for a period of up to the first twelve (12) full calendar months that occur after the Separation Date or until you have secured health insurance coverage through another employer, whichever occurs first ((i)-(ii), the “Severance Benefits”); and (iii) the Company will not contest your eligibility for unemployment insurance benefits following your separation, but reserves the right to truthfully and fully answer any inquiries from any government agency regarding your application for unemployment benefits. The Company will make the separation payment described in clause (i) above on the next standard payday following the Effective Date via direct deposit.

2. Payment of Compensation and Receipt of All Benefits. Between the Transition Date and the Separation Date, you continued your at-will employment with the Company in a non-executive capacity and continued to receive your same compensation and benefits as in effect immediately prior to the Transition Date. You acknowledge and represent that as of the Separation Date, the Company has paid or provided all salary, wages, bonuses, vacation/paid time off, premiums, leaves, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, stock, stock options, vesting, and any and all other benefits and compensation due to you. You acknowledge that, prior to the execution of this Agreement, you were not entitled to receive any additional money from the Company and that the only payments and benefits that you are entitled to receive from the Company in the future are those specified in this Agreement. You acknowledge that (i) your annual bonus for fiscal year 2024 of $504,600, which is based on actual achievement as determined by the Board or its Compensation Committee in its sole discretion, is being paid to you prior to the Separation Date at the same time as bonuses for fiscal year 2024 are being paid to the Company’s other senior executives and (ii) your outstanding Company equity awards that otherwise are scheduled to vest on March 1, 2025 have vested in accordance with their terms on

such date, and that you will not be entitled to additional vesting of your Company equity awards following the Separation Date, including with respect to any earned, but unvested performance-based restricted stock units granted in fiscal 2024.

3. Benefits. Your health insurance benefits ceased on the last day of the month in which the Separation Date occurs (except as otherwise set forth in the Company’s applicable benefit plan(s)), subject to your right to continue your health insurance under COBRA (if any). Your participation in all benefits and incidents of employment, including, but not limited to, vesting in stock options, and the accrual of bonuses, vacation, and paid time off, ceased as of the Separation Date.

4. Acknowledgments. By signing this Agreement, you understand and acknowledge: (a) you are receiving the benefits set forth herein because you have entered into this Agreement and would not otherwise be entitled to receive them otherwise; (b) your signing of and your agreement to this Agreement is knowing and voluntary and that you have not been coerced or threatened; (c) except as otherwise provided in this Agreement, you are not entitled to receive compensation or benefits of any kind from the Company on or after the Separation Date; (d) the Company has properly provided you any leave of absence because of your or a family member’s health condition or military service and you have not been subjected to any improper treatment, conduct or actions due to a request for or taking such leave; (e) you have not suffered or incurred any workplace injury in the course of your employment with the Company on or before the date of your signing this Agreement, other than any injury that was the subject of an injury report or workers’ compensation claim on or before that date; (f) you having had the opportunity to provide the Company with written notice of any and all concerns regarding suspected ethical and compliance issues or violations on the part of the Company or any other Released Party; and (g) you have not filed any complaint, charge, lawsuit, or other legal action that is now pending against the Company or any other Released Party.

5. Release of Claims. In consideration for receiving the benefits described above, to the fullest extent permitted by law, you and your heirs, executors, beneficiaries, successors, assignees, immediate family members, and any other person or entity who could now or hereafter assert a claim in your name or on your behalf waive, release, and forever discharge the Company or its predecessors, successors or past or present subsidiaries, stockholders, directors, officers, former or current employees, consultants, attorneys, agents, assigns and employee benefit plans (“Released Parties”) with respect to any matter, from any and all past, present, or future claims, lawsuits, demands, actions, or causes of actions, whether or not now known (collectively “Claims”), including (without limitation) any matter related to your employment with the Company and/or the termination of that employment. The claims which you agree to release and settle include, but are not limited to: (i) any claim of alleged discrimination, harassment, or retaliation, under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866, the Americans With Disabilities Act, the Equal Pay Act, the Rehabilitation Act, the Genetic Information Nondiscrimination Act, or any other federal, state, or local statute or common law which forbids discrimination, harassment, or retaliation in any aspect of employment; (ii) any claim of negligence, breach of an express or implied employment contract, violation of public policy, wrongful discharge, conspiracy, fraud, infliction of emotional distress, mental or physical injury, or defamation; (iii) any claim for benefits under any of the Company’s employee benefits plans; (iv) any claim for wages, bonuses, commissions, vacation pay, sick pay, severance or compensation of any kind; (v) any claim or violation under any other federal, state, or local statute or common law that may apply in the context of your employment with the Company, including, but not limited to, the Employee Retirement Income Security Act, the False Claims Act, and the federal Worker Adjustment and Retraining Notification Act (WARN Act) or any similar state or local law governing plant closings or mass layoffs; and (vi) any claim for reinstatement, equitable relief, or damages of any kind whatsoever. The scope of what you release in this Agreement includes, but is not limited to, a full general release of any and all Claims or potential Claims that you may have against the Company and/or against any of the other Released Parties, for any and all injunctive relief, declaratory relief, physical injury, personal injury, and injury of any and all other kinds, and/or any and all other kinds of alleged

damages, or other monetary obligation, or obligation of any other sort, including but not limited to, any and all compensatory damages, emotional distress damages, punitive damages, costs, attorneys’ fees, and any and all other kinds of damages that are based in whole or in part on any act or omission occurring before this Agreement becomes effective. However, this release covers only those claims that arose prior to the execution of this Agreement. Execution of this Agreement does not bar any claim that arises hereafter, including (without limitation) a claim for breach of this Agreement. This release of claims does not affect your vested rights in and to any benefit plan to which you may be entitled upon your separation.

6. Waiver. You expressly waive and release any and all rights and benefits under Section 1542 of the California Civil Code (or any analogous law of any other state), which reads as follows:

A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.

You expressly waive and release any and all rights and benefits under Section 1542 of the California Civil Code (or any analogous law of any other state) with respect to the claims released hereby to the full extent allowed by applicable law. In connection with such waiver and release, you acknowledge and agree that you may hereafter discover claims or facts in addition to or different from those which you now know or believe to be true with respect to the matters released herein, but that it is your intention to fully, finally and forever, waive, release and relinquish all such matters and all such claims relative thereto which do exist, may exist, or heretofore have existed. In furtherance of such intention, the release given herein shall be and remain in effect as the full and complete general release of any such additional or different claims or facts relative thereto.

complaint, claim or action seeking to challenge the validity of, or alleging a breach of this Agreement by the Company. In addition, nothing in this Agreement including but not limited to the acknowledgments, release of claims, proprietary information, confidentiality, cooperation, and non-disparagement provisions waives your right to testify in an administrative, legislative, or judicial proceeding concerning alleged criminal conduct or alleged sexual harassment on the part of the Company, or on the part of the agents or employees of the Company, when you have been required or requested to attend such a proceeding pursuant to a court order, subpoena, or written request from an administrative agency or the legislature.

Notwithstanding your confidentiality and non-disclosure obligations in this Agreement and otherwise, you understand that as provided by the Federal Defend Trade Secrets Act, you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret made: (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.

At all times in the future, you will remain bound by your At-Will Employment, Confidential Information, Invention Assignment, and Arbitration Agreement with the Company that you signed on May 25, 2022 (to the extent applicable) (the “Confidentiality Agreement”).

You represent that you have not relied upon any representations or statement in entering into this Agreement which are not specifically set forth in this Agreement.

11. Severability. If any term of this Agreement, with the exception of Section 5, is held to be invalid, void or unenforceable, the remainder of this Agreement will remain in full force and effect and will in no way be affected, and the parties will use their best efforts to find an alternate way to achieve the same result.

12. No Reliance. The parties represent and acknowledge that, in executing this Agreement, they do not rely and have not relied upon any representation or statement made by any of the parties or by any of the parties’ agents, attorneys, or representatives with regard to the subject matter, basis, or effect of this Agreement or otherwise, other than those specifically stated in this written Agreement. In exchange for severance and other promises contained in this Agreement, you are entering into this Agreement voluntarily, deliberately, and with all information needed to make an informed decision to enter this Agreement, and you agree that have been given the opportunity to ask any questions regarding this Agreement and given notice of and an opportunity to retain an attorney or is already represented by an attorney.

13. Section 409A. Notwithstanding anything herein to the contrary, (i) if at the time of your termination of employment with the Company you are a “specified employee” as defined in Section 409A of the Code (and any related regulations or other pronouncements there under) and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in such payments or benefits ultimately paid or provided to you) until the date that is six months following your termination of employment with the Company (or the earliest date as is permitted under Section 409A of the Code) and (ii) if any other payments of money or other benefits due to you hereunder could cause the application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be deferred if deferral will make such payment or other benefits compliant under Section 409A of the Code, or otherwise such payment or other benefits shall be restructured, to the extent possible, in a manner, determined by the Company, that does not cause such an accelerated or additional tax. Each payment made under this Agreement shall be designated as a “separate payment” within the meaning of Section 409A of the Code. The Company shall consult with you in good faith regarding the implementation of the provisions of this Section; provided that neither the Company nor any the Released Parties shall have any liability to you with respect thereto.

14. No Disparagement. Without otherwise limiting your right to participate in protected activity as set forth below, you agree that you will not make any negative or disparaging statements (orally or in writing) about the Company or its directors, officers, investors, customers, employees, products, services or business practices, except as required by law. This Paragraph does not, in any way, restrict or impede you from exercising protected rights to the extent that such rights cannot be waived by agreement or from complying with any applicable law or regulation or a valid order of a court of competent jurisdiction or an authorized government agency, provided that such compliance does not exceed that required by the law, regulation or order. You shall promptly provide written notice of any such order to Company’s Legal Counsel (notices@marqeta.com).

15. No Cooperation. Subject to the Protected Activity provision, you agree that you will not knowingly encourage, counsel, or assist any attorneys or their clients in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints by any third party against any of the Released Parties, unless under a subpoena or other court order to do so or upon written request from an administrative agency or the legislature or as related directly to the ADEA waiver in this Agreement. You agree both to immediately notify the Company upon receipt of any such subpoena or court order or written request from an administrative agency or the legislature, and to furnish, within three (3) business days of its receipt, a copy of such subpoena or other court order or written request from an administrative agency or the legislature. If approached by anyone for counsel or assistance in the presentation or prosecution of any disputes, differences, grievances, claims, charges, or complaints against any of the Released Parties, you shall state no more than that you cannot provide counsel or assistance.
