For the quarter, higher Adjusted EBITDA and margin were primarily driven by Leasing Advisory and Capital Markets Services, reflecting strong revenue growth, with incremental profit contributions from Real Estate Management Services. In addition, margin expansion reflected enhanced platform leverage. Current-quarter performance also reflected lower loan-related expenses, including the absence of loan loss expense recognized in the prior-year quarter. Refer to the segment performance highlights for additional detail.

For the nine months ended September 30, 2026, the significant year-over-year improvement in operating cash flows was driven by higher cash provided by earnings. The Free Cash Flow increase was attributable to the improvement in operating cash flows and also reflected higher capital expenditures, primarily associated with technology infrastructure and investments in workspace optimization.

Total share repurchases are presented below. As of September 30, 2026, $2.5 billion remained authorized for repurchase.

The lower Net Debt, compared with June 30, 2026, was primarily attributable to positive free cash flow for the third quarter. The Net Debt reduction from September 30, 2025, reflected improved free cash flow over the trailing twelve months ended September 30, 2026, compared with the trailing twelve months ended September 30, 2025.

In addition to the Corporate Liquidity detailed above, we maintain a commercial paper program (the "Program") with $2.5 billion authorized for issuance. As of September 30, 2026, there was $113.5 million outstanding under the Program.

Note: For discussion and reconciliation of non-GAAP financial measures, see the Notes following the Financial Statements in this news release. Percentage variances in the Performance Highlights below are calculated and presented on a local currency basis, unless otherwise noted.

Compared with the prior-year quarter, Real Estate Management Services revenue growth was attributable to continued momentum in Workplace Management and accelerated growth in Project Management. Within Workplace Management, the increase was driven by a largely balanced mix of mandate expansions and new client wins. Project Management's double-digit growth follows a strong third-quarter 2025 (up 38% on a two-year stacked basis) with higher pass-through costs augmenting a mid single-digit management fee increase. This growth was led by the U.S. and India, which outpaced softness in Australia and certain geographies in Europe.

Higher Adjusted EBITDA and margin were primarily attributable to the revenue growth described above and incremental platform leverage.

Note (a): Market volume activity is provided by JLL Research.

Higher Leasing Advisory revenue, compared with the prior-year quarter, was driven by accelerated momentum in the U.S., most notably in the industrial, office and data center asset classes. Geographically, the strong U.S. growth (up 39%) significantly outpaced softness in certain geographies within Europe and Asia Pacific. Broad-based asset class growth across the U.S. was primarily due to a meaningful uptick in average deal size. Office leasing revenue growth outperformed global office volumes (up 9% compared with market volumes(a) up 5%), highlighted by U.S. revenue outperformance (up 18% compared with market volumes(a) up 2%). U.S. industrial leasing revenue growth also outperformed industrial volumes (up 56% compared with market volumes(a) up 38%).

The increase in segment platform operating expenses was primarily attributable to higher commission expense, driven by the revenue growth. Consistent with the first half of 2026, larger average deal size drove a higher average commission rate as higher tiers were achieved earlier this year.

Adjusted EBITDA and margin expansion were driven by revenue growth, net of higher commission expense, coupled with incremental platform leverage.

Note (a): Market volume activity is provided by JLL Research.

Capital Markets Services top-line growth was broad-based across nearly all major geographies and sectors, led by investment sales along with robust debt advisory and equity advisory transactions. Investment sales grew 33% (55% on a two-year stacked basis), while debt advisory was up 13% (61% on a two-year stacked basis) and equity advisory was up 39% (126% on a two-year stacked basis) compared with the prior-year quarter. Geographically, the increase in segment revenue was led by the U.S. and Japan. Investment sales revenue growth of 33% globally and 34% in the U.S. outpaced the broader market(a), which grew 9% and 11%, respectively, over the same period.

Higher segment platform operating expenses were substantially driven by increased commission expense, correlating with the strong revenue growth. The higher average commission rate, versus the comparative period, reflected both the earlier achievement of higher commission tiers and the geographic mix of revenue. Segment platform operating expenses also reflected $6.8 million of lower loan-related expenses, including the absence of loan losses recognized in the prior-year quarter.

Higher Adjusted EBITDA and margin expansion for the quarter were primarily attributable to strong revenue growth, net of higher commission expense, as well as lower loan-related expenses noted above and incremental platform leverage.

Compared with the prior-year quarter, lower Incentive and transaction fees drove the decline in Investment Management revenue. Advisory fees were largely steady, as growth from recent capital raising in the Americas was offset by anticipated lower fees from funds in Asia Pacific, as discussed in recent quarters.

The change in Adjusted EBITDA and margin primarily reflected the lower incentive and transaction fees noted above, net of lower incentive compensation costs.

Assets under management (AUM)3 increased 2% in both USD and local currency during the quarter. Over the trailing twelve months, AUM was flat in USD and increased 2% in local currency. Changes in AUM3 are detailed in the tables below (in billions):

Financial Statement Notes

1. 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 the following:

(i)Adjusted EBITDA attributable to common shareholders ("Adjusted EBITDA"),

(ii)Adjusted net income attributable to common shareholders and Adjusted diluted earnings per share,

(iii)Free Cash Flow (refer to Note 6),

(iv)Net Debt (refer to Note 6) and

(v)Percentage changes against prior periods, presented on a local currency basis.

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.

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 2026, the $0.6 million net gain included a $1.0 million gain related to a business disposition within Real Estate Management Services, partially offset by a $0.4 million loss related to a disposition within Capital Markets Services, both during the second quarter.

Interest on Employee Loans, Net of Forgiveness reflects interest accrued on employee loans less the amount of accrued interest forgiven. Certain employees (predominantly in 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 Proptech Investments) 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 for segments other than Investment Management 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, Net reflects changes in the allowance for credit losses associated with pre-equity convertible note investments in early-stage proptech enterprises. Such activity is similar to the equity investment-related gains and losses included in Equity earnings/losses for Proptech Investments and is therefore consistently excluded from adjusted measures.

(a) This adjustment excludes the noncontrolling interest portion which is not attributable to common shareholders.

(b) For the third quarter of 2026, the tax impact of adjusted items was calculated using the consolidated effective tax rate, as this was deemed to approximate the tax impact of adjusted items calculated using the applicable statutory tax rates. For all other periods presented, the tax impact of adjusted items was calculated using the applicable statutory rates by tax jurisdiction.

Operating Results - Local Currency

In discussing operating results, the company refers to percentage changes in local currency, unless otherwise noted. Amounts presented on a local currency basis are calculated by translating the current period results of foreign operations to U.S. dollars using the foreign currency exchange rates from the comparative period. Management believes this methodology provides a framework for assessing performance and operations excluding the effect of foreign currency fluctuations.

The following table reflects the reconciliation to local currency amounts for consolidated (i) Revenue, (ii) Operating income and (iii) Adjusted EBITDA.

2. n.m.: "not meaningful," typically represented by a percentage change of greater than 1,000%, favorable or unfavorable.

3. Assets under management data is primarily reported on a one-quarter lag. In addition, Investment Management raised $0.4 billion in total capital for the quarter ended September 30, 2026.

4. The company defines "Resilient" revenue as (i) Workplace Management, Project Management, Property Management, and Software and Technology Solutions, within Real Estate Management Services, (ii) Value and Risk Advisory, and Loan Servicing, within Capital Markets Services and (iii) Advisory fees, within Investment Management.

The company defines "Advisory" revenue (previously referred to as "Transactional") as (i) Portfolio Services and Other, within Real Estate Management Services, (ii) Leasing Advisory, (iii) Investment Sales, Debt/Equity Advisory and Other, within Capital Markets Services and (iv) Incentive and transaction fees, within Investment Management.

5. Restructuring and acquisition charges are excluded from the company's measure of segment operating results, although they are included within consolidated Operating income. For purposes of segment operating results, the allocation of Restructuring and acquisition charges to the segments is not a component of management's assessment of segment performance. The table below shows Restructuring and acquisition charges.
