CompanyPolicies and Handbook

As a condition of your employment, you agree to comply with all Company policies, procedures, and standards of conduct, including those set forth in the Company’s employee handbook, as may be amended from time to time.

Attachment A

Compensation Plan and Benefits Package


Title	Chief Executive Officer
Salary/Wage	$730,000 per annum
Location	Hybrid, San Jose, CA
Status	Full-time Regular Exempt
Incentive Compensation Plan (“ICP”)	Target of 100% of base salary with the bonus amount based upon the Company’s achievement of its financial objectives and upon the achievement of individual objectives in accordance with the ICP. For 2026, the bonus amount will be prorated from your Start Date.
Benefits	When you join Adeia, you will be eligible to participate in certain benefit plans and programs that are generally afforded to U.S. Adeia employees and executives (including medical, dental, vision, 401(k), and life insurance), in accordance with and subject to the terms and conditions applicable to those plans and programs. All benefit plans and programs to which you are eligible to participate (and the policies associated therewith) may be modified, supplemented, changed or terminated (including with prospective effect) at any time. Some or all of these plans may require contributions from you and may also be subject to waiting periods for new employees. The People Team will provide you with details of the plans and programs to which you are eligible on or prior to your start date and you will be able to select benefits during your first 30 days of employment.


Equity Awards	You will be granted new hire equity awards under Adeia’s Amended and Restated 2020 Equity Incentive Plan with a target grant value of $11,000,000. The new hire equity awards will be issued as two grants: (i) a new hire restricted stock unit (“RSU”) award with a grant date value of $4,400,000, which shall be composed entirely of time-based RSU shares (vesting over four years per the Company’s standard vesting terms), and (ii) a performance-based RSU (“PRSU”) award with a target grant date value of $6,600,000 (vesting based on terms and conditions described below). The grant date of the new hire equity awards shall be your Start Date. In order to vest a portion of an award on a given vesting date, you must be employed by Adeia on such vesting date. The amount of shares subject to the new hire RSUs and the target amount of shares subject to the new hire PRSUs will be determined based upon the average closing price of Adeia common stock for the 30 trading day period ending on the last trading day before the grant date, rounded up or down to the nearest 10 shares and such new hire equity awards will vest in accordance with the terms and conditions of the applicable grant notice and agreement, which will be delivered under separate cover. The new hire PRSUs will be earned based on the Company's EBITDA (excluding litigation) achievement measured annually over a three-year performance period commencing on your employment start date, with each calendar year during the performance period having earned shares banked at 0% (below threshold), 50% (threshold), 100% (target) or 200% (maximum) of that calendar year's target banking opportunity (using linear interpolation between those points and prorated as applicable for partial calendar years 2026 and 2029 that occur during the performance period), and the aggregate banked shares further adjusted, up or down, by up to 33% based on the Company's relative total shareholder return (rTSR) over the performance period, subject to an overall payout range of 0% to 200% of target. Shares banked in respect of each performance year will not vest until the end of the three-year performance period, at which time all banked (and rTSR-adjusted) shares will vest, if at all, in a single vesting event, subject to continued employment through the vesting date and certification by the Compensation Committee. You will also be eligible to receive Adeia’s next annual merit/refresh equity grant in 2027, consistent with Adeia’s practice for other senior executives.
Severance	You will enter into a CEO severance agreement, including any customary attachments, in a form acceptable to Adeia.
Legal Expenses	The Company agrees to reimburse up to $20,000 of your out-of-pocket legal expenses incurred in connection with the evaluation and consideration of your employment with the Company.
