Non-GAAP measures Management uses certain non-GAAP financial measures to develop budgets and forecasts, measure and reward performance against those budgets and forecasts, and enhance comparability to prior periods. These measures are believed to be useful to investors and other external stakeholders as supplemental measures of core operating performance and include Adjusted EBITDA attributable to common shareholders ("Adjusted EBITDA"). However, non-GAAP financial measures should not be considered alternatives to measures determined in accordance with U.S. generally accepted accounting principles (“GAAP”). Any measure that eliminates components of a company’s capital structure, cost of operations or investments, or other results has limitations as a performance measure. In light of these limitations, management also considers GAAP financial measures and does not rely solely on non-GAAP financial measures. Because the company's non-GAAP financial measures are not calculated in accordance with GAAP, they may not be comparable to similarly titled measures used by other companies. Adjustments to GAAP Financial Measures Used to Calculate non-GAAP Financial Measures Net Non-Cash Mortgage Servicing Rights ("MSR") and Mortgage Banking Derivative Activity consists of the balances presented within Revenue composed of (i) derivative gains/losses resulting from mortgage banking loan commitment and warehousing activity and (ii) gains recognized from the retention of MSR upon origination and sale of mortgage loans, offset by (iii) amortization of MSR intangible assets over the period that net servicing income is projected to be received. Non-cash derivative gains/losses resulting from mortgage banking loan commitment and warehousing activity are calculated as the estimated fair value of loan commitments and subsequent changes thereof, primarily represented by the estimated net cash flows associated with future servicing rights. MSR gains and corresponding MSR intangible assets are calculated as the present value of estimated cash flows over the estimated mortgage servicing periods. The above activity is reported entirely within Revenue of the Capital Markets Services segment. Excluding net non-cash MSR and mortgage banking derivative activity reflects how the company manages and evaluates performance because the excluded activity is non-cash in nature. 19 | © 2025 Jones Lang LaSalle IP, Inc.

Non-GAAP measures (cont.) Restructuring and Acquisition Charges primarily consist of: (i) severance and employment-related charges, including those related to external service providers, incurred in conjunction with a structural business shift, which can be represented by a notable change in headcount, change in leadership or transformation of business processes; (ii) acquisition, transaction and integration-related charges, including fair value adjustments, which are generally non-cash in the periods such adjustments are made, to assets and liabilities recorded in purchase accounting such as earn-out liabilities and intangible assets; and (iii) lease exit charges. Such activity is excluded as the amounts are generally either non-cash in nature or the anticipated benefits from the expenditures would not likely be fully realized until future periods. Restructuring and acquisition charges are excluded from segment operating results and therefore are not line items in the segments’ reconciliation to Adjusted EBITDA. Amortization of Acquisition-Related Intangibles is primarily associated with the fair value ascribed at closing of an acquisition to assets such as acquired management contracts, customer backlog and relationships, and trade name. Such activity is excluded as it is non-cash and the change in period-over-period activity is generally the result of longer-term strategic decisions and therefore not necessarily indicative of core operating results. Gain or Loss on Disposition reflects the gain or loss recognized on the sale of businesses. Given the low frequency of business disposals by the company historically, the gain or loss directly associated with such activity is excluded as it is not considered indicative of core operating performance. In 2023, the $0.5 million net loss included $1.8 million of loss related to the disposition of a business in Leasing Advisory, partially offset by a $1.3 million gain related to the disposition of a business in Leasing Advisory and Capital Markets Services. Interest on Employee Loans, Net of Forgiveness reflects interest accrued on employee loans less the amount of accrued interest forgiven. Certain employees (predominantly in our Leasing Advisory and Capital Markets Services businesses) receive cash payments structured as loans, with interest. Employees earn forgiveness of the loan based on performance, generally calculated as a percentage of revenue production. Such forgiven amounts are reflected in Compensation and benefits expense. Given the interest accrued on these employee loans and subsequent forgiveness are non-cash and the amounts perfectly offset over the life of the loan, the activity is not indicative of core operating performance and is excluded from non-GAAP measures. Equity Earnings/Losses (Investment Management and Software and Technology Solutions) primarily reflects valuation changes on investments reported at fair value. Investments reported at fair value are increased or decreased each reporting period by the change in the fair value of the investment. Where the measurement alternative has been elected, our investment is increased or decreased upon observable price changes. Such activity is excluded as the amounts are generally non-cash in nature and not indicative of core operating performance. Note: Equity earnings/losses in the remaining segments represent the results of unconsolidated operating ventures (not investments), and therefore the amounts are included in adjusted profit measures on both a segment and consolidated basis. Credit Losses on Convertible Note Investments reflects credit impairments associated with pre-equity convertible note investments in early-stage proptech enterprises. Such losses are similar to the equity investment-related losses included in equity earnings/losses for Software and Technology Solutions' investments and are therefore consistently excluded from adjusted measures. 20 | © 2025 Jones Lang LaSalle IP, Inc.
