Retirement Agreement and General Release of Claims by and between Nasdaq, Inc. and Michael Ptasznik, dated October 21, 2020

This General Release and Retirement Agreement (“Agreement”), reflects our mutual agreement and understanding concerning your retirement from Nasdaq, Inc. or any of its subsidiaries or affiliates (the “Company”), as set forth below. Please review the following information and address any questions you may have concerning this notice to the Chief People Officer, Bryan Smith. This Agreement becomes valid upon the Company’s receipt of your signed and dated copy.

a.As of February 28, 2021 (“Retirement Date”), you will retire from your service as an employee of the Company. Between October 21, 2020 (“Transition Date”) and your Retirement Date (the “Transition Period”), you agree to perform the duties of Executive Vice President, Strategy and Chief Financial Officer as assigned by the President and CEO. During the Transition Period, your regular salary will remain unchanged at $625,000 per annum and you shall remain fully eligible for participation in the Company’s benefits plans in which you now participate through the Retirement Date. You will also be paid for all accrued but unused vacation and any unreimbursed business expenses (in accordance with Company policy), after your Retirement Date (or earlier separation).

You will receive a bonus payment under the Executive Incentive Plan for 2020 based upon your performance and target bonus opportunity of $937,500. The 2020 bonus will be paid on or about March 2, 2021. If Nasdaq terminates your employment due to gross misconduct or gross negligence, or you voluntarily resign before December 31, 2020, you will not be entitled to any part of the 2020 CIP bonus. You will receive a bonus payment under the Executive Incentive Plan for 2021 based upon your target bonus opportunity of $937,500, prorated for the period of January 1, 2021 though the Retirement Date. The 2021 bonus will be paid on or about March 2, 2021. All equity grants normally scheduled to vest prior to the Retirement Date shall vest on schedule.

If you do not execute this Agreement, your health benefits provided through the Company will continue through the end of the last month of your employment. Pursuant to federal law, and independent of this Agreement, you and your eligible dependents will be eligible to elect benefits continuation coverage if you timely apply for COBRA benefits. Information regarding your rights under COBRA will be provided to you in a separate mailing. If you choose to accept the offer of separation and

benefits set forth in Paragraph 2 of this Agreement, your group health, vision, and dental benefits will end on the Retirement Date. You will be separately notified of your benefit conversion privileges and COBRA rights.

In consideration for signing this Agreement, in full settlement of any compensation and benefits to which you would otherwise be entitled, and in exchange for the promises, covenants, releases, and waivers set forth herein:

a.The Company agrees to continue to pay the employer’s share of your medical, dental and vision premiums for 12 months after your Retirement Date. You will still be responsible for paying the employee share of the premium, which will be the same contribution paid as an active employee would pay for this coverage, as specified by the plan administrator.

b.Unless your employment ends any time before February 28, 2021 due to your resignation, gross misconduct, or gross negligence, you will remain eligible for (i) continued vesting and payment of the ThreeYear Performance Share Units (“PSU's”) granted on April 1, 2019 ("2019 Grant") and on April 1, 2020 ("2020 Grant"), and (ii) vesting of the RSUs granted on April 1, 2020 (“2020 RSU Grant), with accelerated vesting of any unvested RSUs within 60 days from your Retirement Date. To the extent this Agreement conflicts with all relevant PSU and RSU Agreements, this Agreement will apply, provided that the time and form of settlement of the PSU's shall be governed by the terms of the applicable award agreement and governing plan document. Consistent with the Nasdaq Equity Plan, in the event a change in control event occurs after your Retirement Date, all unvested awards shall vest immediately, at target, prior to the effective time of such change in control. Upon termination of employment due to death, your Estate shall be entitled to receive accelerated vesting of all unvested equity compensation awarded to you as of that date. All other benefits, if any, due to your estate shall be determined in accordance with the plans, policies and practices of the Company in effect at that time.

c.The Company will continue to provide, following your Retirement Date, financial and tax services (currently provided by PWC) for tax years 2020, 2021, 2022 and 2023, and executive physical exams (currently provided by EHE International) for 1 year.

d.The Company will reimburse reasonable and customary expenses to move back to your home country, Canada, up to $10,000.

e.If you accept another position with the Company, or materially violate the terms of any employment restrictions noted herein and such violation remains uncured after written notice from the Company, while you are receiving separation payments and benefits under this paragraph, you will not receive any additional separation payments and benefits following your start date in the new position or date of such material violation.
