This letter documents your appointment to Chief Financial Officer of Jones Lang LaSalle, Inc. (“JLL”) effective July 1, 2025 (the “Effective Date”). In this role you will report to the Chief Executive Officer, Christian Ulbrich, and be a member of the GEB.

As of the Effective Date, your annualized base salary will be $600,000, paid every other Friday in arrears less applicable payroll deductions. In future years, your base salary will be subject to review by the Compensation Committee of JLL’s Board of Directors in accordance with the procedures followed for all GEB members. We do not guarantee any base salary increases.

You will be eligible for the GEB Annual Incentive Plan (“GEB AIP”). Your 2025 annualized GEB AIP target bonus is $1,000,000, which will be prorated for the time in your new role after the Effective Date. Bonus payout levels will vary from year to year. Your actual bonus will be based on (i) your performance against the specific individual goals you will develop with your manager and (ii) JLL’s overall performance. Upon consideration of these factors and others, you may receive more than, less than, or none of your target bonus amount. Bonuses are considered annually and are typically paid in March of the following year subject to all other terms and conditions of eligibility.

Bonus payments are discretionary. You must be employed on the date bonuses are paid to receive a bonus payment. If you leave JLL for any reason before the payment date, you will not receive a bonus payout, pro rata or otherwise.

Following the Effective Date, you will be eligible for the GEB Long-Term Incentive Plan (“GEB LTIP”). Your GEB LTIP target is $1,500,000. The first anticipated grant at your new target level is expected to occur in 1Q 2026 and be delivered in a mix of Performance Stock Units (“PSUs”) and Restricted Stock Units (“RSUs”).

PSUs are subject to JLL’s firm-wide performance metrics as determined by the JLL Board of Directors and will vary the number of Units you receive up or down based on performance against set targets. Awards are subject to approval by the JLL Board of Directors. All terms of this award will be governed by the Jones Lang LaSalle 2019 Amended and Restated Stock Award and Incentive Plan (“SAIP”) and your award agreement. JLL reserves the right to alter the GEB LTIP from time to time in its sole discretion, which may include target award and equity vehicle changes.

You will be eligible for a one-time grant of Restricted Stock Units (RSUs) in the amount of $675,000 in September 2025. The number of shares will be determined based on the trailing 20-day average closing price of JLL stock, starting on the sixth (6th) trading day prior to the grant date and working backward 20 consecutive trading days. The shares will vest ratably over three years on each anniversary of the grant date through 2028. Awards are subject to approval by the JLL Board of Directors and all terms of this award will be governed by the SAIP and your award agreement.

As a GEB member, you are required to maintain JLL share ownership (inclusive of unvested RSUs) at least equal to the lesser of (i) one time your annual long-term incentive grant, or (ii) four times your annual base salary. Members of the GEB must also retain 75% of all shares acquired on the vesting of equity awards or the exercise of stock options until compliance with the minimum ownership requirement is achieved. After you attain the minimum required ownership level, you must hold 50% of any shares acquired on the vesting of equity awards or the exercise of stock options for two years following such vesting or exercise. Requirements are subject to change based on the normal review process of the Compensation Committee of the JLL Board of Directors.
