As a salaried, exempt employee of MarketWise, LLC, you will be expected to work the Company’s normal business hours and additional hours as required by your job duties, and you will not be eligible for overtime pay.

•Annual Incentive Bonus. Each performance year, you will be eligible to receive an annual incentive bonus (the “bonus”) composed of cash and/or equity awards for the services you render under this Letter Agreement. Your bonus structure will be reviewed annually by the Company’s Compensation Committee.

For 2023 and until amended, the cash bonus will be equal to 1.5% of net income* up to a maximum of $2.25 million dollars. You are also eligible for a discretionary bonus

of up to an additional .25% of net income*. Allocation of the discretionary portion of the bonus, if any, will be based on the Compensation Committee’s assessment of any individual goals related to your leadership in the role of CEO. In addition, you will be eligible for an annual equity award of RSUs with a target economic value of 1.25M, subject to vesting requirements set forth in the applicable equity award agreement.
