Organization and Basis of Presentation
Organization and Basis of Presentation	1. Organization JBG SMITH Properties ("JBG SMITH"), a Maryland real estate investment trust, owns, operates, invests in and develops mixed-use properties in high growth and high barrier-to-entry submarkets in and around Washington, D.C., most notably National Landing. Through an intense focus on placemaking, JBG SMITH cultivates vibrant, amenity-rich, walkable neighborhoods throughout the Washington, D.C. metropolitan area. Approximately 75.0% of our holdings are in the National Landing submarket in Northern Virginia, which is anchored by four key demand drivers: Amazon.com, Inc.'s ("Amazon") new headquarters; Virginia Tech's under-construction $1 billion Innovation Campus; the submarket’s proximity to the Pentagon; and our retail and digital placemaking initiatives and public infrastructure improvements. In addition, our third-party asset management and real estate services business provides fee-based real estate services to the legacy funds formerly organized by The JBG Companies ("JBG") (the "JBG Legacy Funds") and other third parties. Substantially all our assets are held by, and our operations are conducted through, JBG SMITH Properties LP ("JBG SMITH LP"), our operating partnership. As of September 30, 2024, JBG SMITH, as its sole general partner, controlled JBG SMITH LP and owned 85.8% of its OP Units, after giving effect to the conversion of certain vested long-term incentive partnership units ("LTIP Units") that are convertible into OP Units. JBG SMITH is referred to herein as "we," "us," "our" or other similar terms. References to "our share" refer to our ownership percentage of consolidated and unconsolidated assets in real estate ventures, but exclude our: (i) 10.0% subordinated interest in one commercial building, (ii) 33.5% subordinated interest in four commercial buildings (the "Fortress Assets") and (iii) 49.0% interest in three commercial buildings (the "L'Enfant Plaza Assets"), as well as the associated non-recourse mortgage loans, held through unconsolidated real estate ventures; these interests and debt are excluded because our investment in each real estate venture is zero, we do not anticipate receiving any near-term cash flow distributions from the real estate ventures, and we have not guaranteed their obligations or otherwise committed to providing financial support. We were organized for the purpose of receiving, via the spin-off on July 17, 2017 (the "Separation"), substantially all of the assets and liabilities of Vornado Realty Trust's ("Vornado") Washington, D.C. segment. On July 18, 2017, we acquired the management business, and certain assets and liabilities of JBG (the "Combination"). The Separation and the Combination are collectively referred to as the "Formation Transaction." As of September 30, 2024, our Operating Portfolio consisted of 41 operating assets comprising 16 multifamily assets totaling 6,781 units (6,781 units at our share), 23 commercial assets totaling 7.2 million square feet (6.9 million square feet at our share) and two wholly owned land assets for which we are the ground lessor. Additionally, we have one under-construction multifamily asset with 775 units (775 units at our share) and 18 assets in the development pipeline totaling 11.4 million square feet (9.3 million square feet at our share) of estimated potential development density. We derive our revenue primarily from leases with multifamily and commercial tenants. Our commercial leases include fixed and percentage rents, and reimbursements from tenants for certain expenses such as real estate taxes, property operating expenses, and repairs and maintenance. In addition, our third-party asset management and real estate services business provides fee-based real estate services. Basis of Presentation The accompanying unaudited condensed consolidated financial statements and notes are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not contain certain information required in annual financial statements and notes as required under GAAP. In our opinion, all adjustments considered necessary for a fair presentation have been included, and all such adjustments are of a normal recurring nature. All intercompany transactions and balances have been eliminated. The results of operations for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of the results that may be expected for a full year. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission ("SEC") on February 20, 2024 ("Annual Report"). The accompanying condensed consolidated financial statements include our accounts and those of our wholly owned subsidiaries and consolidated variable interest entities ("VIEs"), including JBG SMITH LP. See Note 5 for additional information. The portions of the equity and net income (loss) of consolidated entities that are not attributable to us are presented separately as amounts attributable to noncontrolling interests in our condensed consolidated financial statements. References to our financial statements refer to our unaudited condensed consolidated financial statements as of September 30, 2024 and December 31, 2023, and for the three and nine months ended September 30, 2024 and 2023. References to our balance sheets refer to our condensed consolidated balance sheets as of September 30, 2024 and December 31, 2023. References to our statements of operations refer to our condensed consolidated statements of operations for the three and nine months ended September 30, 2024 and 2023. References to our statements of comprehensive loss refer to our condensed consolidated statements of comprehensive loss for the three and nine months ended September 30, 2024 and 2023. Income Taxes We have elected to be taxed as a real estate investment trust ("REIT") under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"). Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. We currently adhere and intend to continue to adhere to these requirements and to maintain our REIT status in future periods. We also participate in the activities conducted by our subsidiary entities that have elected to be treated as taxable REIT subsidiaries under the Code. As such, we are subject to federal, state and local taxes on the income from those activities.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Significant Accounting Policies There were no material changes to our significant accounting policies disclosed in our Annual Report. Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Recent Accounting Pronouncements Standards Not Yet Adopted Climate-Related Disclosures In March 2024, the SEC issued final rules on the enhancement and standardization of climate-related disclosures. The rules require disclosure of, among other things, (i) actual and potential material impacts of climate-related risks on our strategy, business model and outlook, (ii) climate-related targets and goals that have materially affected or are reasonably likely to materially affect our business, results of operations or financial condition, (iii) governance and management of climate-related risks and (iv) material Scope 1 and Scope 2 greenhouse gas emissions. Additionally, the rules require disclosures in the notes to the financial statements regarding the effects of severe weather events and other natural conditions, subject to certain materiality thresholds, and certain carbon offsets and renewable energy certificates. The rules are effective on a phased-in timeline beginning in the annual reports for the year ended December 31, 2025. In April 2024, the SEC announced a stay of these climate disclosure rules pending judicial review. We are currently evaluating the potential impact of adopting these new rules on our disclosures. Income Taxes In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("Topic 740"). Topic 740 modifies the rules on income tax disclosures to require entities to disclose (i) specific categories in the rate reconciliation, (ii) the income (loss) from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (iii) income tax expense or benefit from continuing operations (separated by federal, state and foreign). Topic 740 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. This guidance should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the potential impact of adopting this new guidance on our financial statement disclosures. Segment Reporting In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segments Disclosures" ("Topic 280"). Topic 280 enhances disclosures of significant segment expenses and other segment items regularly provided to the chief operating decision maker ("CODM"), extends certain annual disclosures to interim periods and permits more than one measure of segment profit (loss) to be reported under certain conditions. Topic 280 does not change the existing guidance on how a public entity identifies and determines its reportable segments. The amendments are effective in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Retrospective adoption to all periods presented is required, and early adoption of the amendments is permitted. We are currently evaluating the potential impact of adopting this new guidance on our financial statement disclosures.

Variable Interest Entities

Variable Interest Entities	9 Months Ended

Variable Interest Entities
Variable Interest Entities	5. We hold various interests in entities deemed to be VIEs, which we evaluate at acquisition, formation, after a change in the ownership agreement, after a change in the entity's economics or after any other reconsideration event to determine if the VIE should be consolidated in our financial statements or should no longer be considered a VIE. An entity is a VIE because it is in the development stage and/or does not hold sufficient equity at risk or conducts substantially all its operations on behalf of an investor with disproportionately few voting rights. We will consolidate a VIE if we are the primary beneficiary of the VIE, which entails having the power to direct the activities that most significantly impact the VIE’s economic performance. Certain criteria we assess in determining whether we are the primary beneficiary of the VIE include our influence over significant business activities, our voting rights and any noncontrolling interest kick-out or participating rights. Unconsolidated VIEs As of September 30, 2024 and December 31, 2023, we had interests in entities deemed to be VIEs. Although we may be responsible for managing the day-to-day operations of these investees, we are not the primary beneficiary of these VIEs, as we do not hold unilateral power over activities that, when taken together, most significantly impact the respective VIE's economic performance. We account for our investment in these entities under the equity method. As of September 30, 2024 and December 31, 2023, the net carrying amounts of our investment in these entities were $88.6 million and $87.3 million, which were included in "Investments in unconsolidated real estate ventures" in our balance sheets. Our equity in the income of unconsolidated VIEs was included in "Income (loss) from unconsolidated real estate ventures, net" in our statements of operations. Our maximum loss exposure in these entities is limited to our investments, construction commitments and debt guarantees. See Note 17 for additional information. Consolidated VIEs JBG SMITH LP is our most significant consolidated VIE. We hold 85.8% of the limited partnership interest in JBG SMITH LP, act as the general partner and exercise full responsibility, discretion and control over its day-to-day management. The noncontrolling interests of JBG SMITH LP do not have substantive liquidation rights, substantive kick-out rights without cause or substantive participating rights that could be exercised by a simple majority of noncontrolling interest limited partners (including by such a limited partner unilaterally). Because the noncontrolling interest holders do not have these rights, JBG SMITH LP is a VIE. As general partner, we have the power to direct the activities of JBG SMITH LP that most significantly affect its economic performance, and through our majority interest, we have both the right to receive benefits from and the obligation to absorb losses of JBG SMITH LP. Accordingly, we are the primary beneficiary of JBG SMITH LP and consolidate it in our financial statements. Because we conduct our business through JBG SMITH LP, its total assets and liabilities comprise substantially all our consolidated assets and liabilities. In March 2021, we leased the land underlying 1900 Crystal Drive located in National Landing to a lessee, which constructed an 808-unit multifamily asset comprising two towers, The Grace and Reva, with ground floor retail. The ground lessee engaged us to be the development manager for the construction of 1900 Crystal Drive, and separately, we were the lessee in a master lease of the asset. We determined that 1900 Crystal Drive was a VIE and that we were the primary beneficiary of the VIE. Accordingly, we consolidated the VIE with the lessee's ownership interest shown as "Noncontrolling interests" in our balance sheet. In June 2024, we acquired the ground lessee's interest in 1900 Crystal Drive for $26.6 million of which $4.7 million was a reduction of "Noncontrolling interests" in our balance sheet. As a result of the transaction, 1900 Crystal Drive is no longer a VIE. As of September 30, 2024, excluding JBG SMITH LP, we consolidated one VIE (2000/2001 South Bell Street) with total assets of $271.4 million and liabilities of $173.1 million, and as of December 31, 2023, excluding JBG SMITH LP, we consolidated two VIEs (1900 Crystal Drive and 2000/2001 South Bell Street) with total assets of $503.2 million and liabilities of $293.3 million. VIE assets primarily consisted of construction in progress and VIE liabilities primarily consisted of mortgage loans. The assets of the VIEs can only be used to settle the obligations of the VIEs, and the liabilities include third-party liabilities of the VIEs for which the creditors or beneficial interest holders do not have recourse against us. In October 2024, we provided notice of our intent to exercise our option to acquire the ground lessee’s interest in 2000/2001 South Bell Street which we anticipate will close in the fourth quarter of 2024.

As of September 30, 2024 and December 31, 2023, the net carrying value of real estate collateralizing our mortgage loans totaled $2.1 billion and $2.2 billion. Our mortgage loans contain covenants that limit our ability to incur additional indebtedness on these properties and, in certain circumstances, require lender approval of tenant leases and/or yield maintenance upon repayment prior to maturity. In September 2024, we repaid the $83.3 million mortgage loan collateralized by 201 12th Street S., 200 12th Street S., and 251 18th Street S. As of September 30, 2024 and December 31, 2023, we had various interest rate swap and cap agreements on certain mortgage loans with an aggregate notional value of $1.7 billion. See Note 15 for additional information.

Share-Based Payments	11. LTIP Units and Time-Based LTIP Units In January 2024, we granted to certain employees 974,140 LTIP Units with time-based vesting requirements ("Time-Based LTIP Units") and a weighted average grant-date fair value of $15.93 per unit that primarily vest ratably over four years subject to continued employment. Compensation expense for these units is primarily being recognized over a four-year period. In January 2024, we granted 209,047 fully vested LTIP Units to certain employees, who elected to receive all or a portion of their cash bonuses related to 2023 service as LTIP Units. The LTIP units had a grant-date fair value of $14.27 per unit. Compensation expense totaling $3.0 million for these LTIP Units was recognized in 2023. In April 2024, as part of their annual compensation, we granted to non-employee trustees a total of 141,422 fully vested LTIP Units with a grant-date fair value of $12.40 per unit, which includes LTIP Units elected in lieu of cash retainers. The LTIP Units may not be sold while a trustee is serving on the Board of Trustees. The aggregate grant-date fair value of the Time-Based LTIP Units and the LTIP Units granted during the nine months ended September 30, 2024 was $20.3 million. The Time-Based LTIP Units and the LTIP Units were valued based on the closing common share price on the grant date, less a discount for post-grant restrictions. The discount was determined using Monte Carlo simulations based on the following significant assumptions: ​ ​ ​ ​ Expected volatility 33.0 % to 35.0% Risk-free interest rate 4.4% to 4.8% Post-grant restriction periods 2 to 6 years ​ Appreciation-Only LTIP Units ("AO LTIP Units") In January 2024, we granted to certain employees 1.9 million performance-based AO LTIP Units with a grant-date fair value of $3.79 per unit. The AO LTIP Units provide for a share of appreciation determined by the increase in the value of a common share at the time of conversion over the participation threshold of $18.93. The AO LTIP Units are subject to a TSR modifier whereby the number of AO LTIP Units that will ultimately be earned will be increased or reduced by 25%. The AO LTIP Units have a three-year performance period with 50% of the AO LTIP Units earned vesting at the end of the three-year performance period and the remaining 50% vesting on the fourth anniversary of the grant date, subject to continued employment. The AO LTIP Units expire on the ten The aggregate grant-date fair value of the AO LTIP Units granted during the nine months ended September 30, 2024 was $7.1 million, valued using Monte Carlo simulations based on the following significant assumptions: ​ ​ ​ ​ Expected volatility 32.0% Dividend yield 3.2% Risk-free interest rate 4.1% ​ Restricted Share Units ("RSUs") In January 2024, we granted to certain non-executive employees 74,842 time-based RSUs ("Time-Based RSUs") with a grant-date fair value of $17.21 per unit. Vesting requirements and compensation expense recognition for the Time-Based RSUs are primarily consistent with those of the Time-Based LTIP Units granted in 2024. The aggregate grant-date fair value of the RSUs granted during the nine months ended September 30, 2024 was $1.3 million. The Time-Based RSUs were valued based on the closing common share price on the date of grant. ESPP Pursuant to the ESPP, employees purchased 60,185 common shares for $792,000 during the nine months ended September 30, 2024, valued using the Black-Scholes model based on the following significant assumptions: ​ ​ ​ ​ Expected volatility 26.0% to 48.0% Dividend yield 4.2% to 4.6% Risk-free interest rate 5.3% to 5.6% Expected life ​ 3 months ​ Share-Based Compensation Expense The following is a summary of share-based compensation expense: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ 2024 2023 X 2024 2023 ​ (In thousands) Time-Based LTIP Units ​ $ 3,191 ​ $ 3,517 ​ $ 14,548 ​ $ 14,373 AO LTIP Units and Performance-Based LTIP Units ​ 1,233 ​ 2,440 ​ 8,187 ​ 9,382 LTIP Units ​ — ​ — ​ 1,552 ​ 1,000 Other equity awards (1) ​ 1,082 ​ 912 ​ 3,294 ​ 3,710 Share-based compensation expense - other ​ 5,506 ​ 6,869 ​ 27,581 ​ 28,465 Share-based compensation related to Formation Transaction and special equity awards (2) ​ — ​ 46 ​ — ​ 397 Total share-based compensation expense ​ 5,506 ​ 6,915 ​ 27,581 ​ 28,862 Less: amount capitalized ​ (377) ​ (418) ​ (1,423) ​ (1,851) Share-based compensation expense ​ $ 5,129 ​ $ 6,497 ​ $ 26,158 ​ $ 27,011 (1) Primarily comprising compensation expense for: (i) fully vested LTIP Units issued to certain employees in lieu of all or a portion of any cash bonuses earned, (ii) RSUs and (iii) shares issued under our ESPP.

Shareholders' Equity and Loss Per Common Share	14. Common Shares Repurchased Our Board of Trustees has authorized the repurchase of up to $1.5 billion of our outstanding common shares. During the three and nine months ended September 30, 2024, we repurchased and retired 3.1 million and 10.8 million common shares for $50.2 million and $168.3 million, a weighted average purchase price per share of $16.23 and $15.61. During the three and nine months ended September 30, 2023, we repurchased and retired 7.9 million and 18.4 million common shares for $120.8 million and $276.7 million, a weighted average purchase price per share of $15.24 and $14.98. Since we began the share repurchase program through September 30, 2024, we have repurchased and retired 56.6 million common shares for $1.1 billion, a weighted average purchase price per share of $19.88. Loss Per Common Share Basic earnings (loss) per common share is computed by dividing net income (loss) available to common shareholders by the weighted average common shares outstanding during the period. Unvested share-based compensation awards that entitle holders to receive non-forfeitable distributions are considered participating securities. Consequently, we are required to apply the two-class method of computing basic and diluted earnings (loss) that would otherwise have been available to common shareholders. Under the two-class method, earnings for the period are allocated between common shareholders and participating securities based on their respective rights to receive dividends. During periods of net loss, losses are allocated only to the extent the participating securities are required to absorb their share of such losses. Distributions to participating securities in excess of their allocated income or loss are shown as a reduction to net income (loss) attributable to common shareholders. Diluted earnings (loss) per common share reflects the potential dilution of the assumed exchange of various unit and share-based compensation awards into common shares to the extent they are dilutive. The following is a summary of the calculation of basic and diluted loss per common share and a reconciliation of net loss to the amounts of net loss available to common shareholders used in calculating basic and diluted loss per common share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended September 30, ​ Nine Months Ended September 30, ​ ​ 2024 2023 X 2024 2023 ​ ​ (In thousands, except per share amounts) Net loss ​ $ (31,309) ​ $ (66,101) ​ $ (106,913) ​ $ (54,045) Net loss attributable to redeemable noncontrolling interests ​ ​ 4,365 ​ 7,926 ​ 12,353 ​ 5,961 Net (income) loss attributable to noncontrolling interests ​ ​ (36) ​ 168 ​ 10,931 ​ 703 Net loss attributable to common shareholders ​ ​ (26,980) ​ ​ (58,007) ​ ​ (83,629) ​ ​ (47,381) Distributions to participating securities ​ ​ (439) ​ ​ (689) ​ (1,596) ​ (1,406) Net loss available to common shareholders - basic and diluted ​ $ (27,419) ​ $ (58,696) ​ $ (85,225) ​ $ (48,787) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted average number of common shares outstanding - basic and diluted ​ ​ 85,292 ​ ​ 101,445 ​ 89,637 ​ 108,351 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loss per common share - basic and diluted ​ $ (0.32) ​ $ (0.58) ​ $ (0.95) ​ $ (0.45) ​ The effect of the redemption of OP Units, Time-Based LTIP Units, fully vested LTIP Units and special equity awards that were outstanding as of September 30, 2024 and 2023 is excluded in the computation of diluted loss per common share as the assumed exchange of such units for common shares on a one-for-one basis was antidilutive (the assumed redemption of these units would have no impact on the determination of diluted loss per share). Since OP Units, Time-Based LTIP Units, LTIP Units and special equity awards, which are held by noncontrolling interests, are attributed gains at an identical proportion to the common shareholders, the gains attributable and their equivalent weighted average impact are excluded from loss available to common shareholders and from the weighted average number of common shares outstanding in calculating diluted loss per common share. AO LTIP Units, Performance-Based LTIP Units, formation awards and RSUs, which totaled 7.9 million for the three and nine months ended September 30, 2024, and 6.6 million and 6.9 million for the three and nine months ended September 30, 2023, were excluded from the calculation of diluted loss per common share as they were antidilutive, but potentially could be dilutive in the future. ​ Dividends Declared in October 2024 On October 24, 2024, our Board of Trustees declared a quarterly dividend of $0.175 per common share, payable on November 22, 2024 to shareholders of record as of November 7, 2024.

Fair Value Measurements
Fair Value Measurements	15. Fair Value Measurements on a Recurring Basis To manage or hedge our exposure to interest rate risk, we follow established risk management policies and procedures, including the use of a variety of derivative financial instruments. As of September 30, 2024 and December 31, 2023, we had various derivative financial instruments consisting of interest rate swap and cap agreements that are measured at fair value on a recurring basis. The net unrealized gain (loss) on our derivative financial instruments designated as effective hedges was ($1.8) million and $22.7 million as of September 30, 2024 and December 31, 2023 and was recorded in "Accumulated other comprehensive income (loss)" in our balance sheets, of which a portion was allocated to "Redeemable noncontrolling interests." Within the next 12 months, we expect to reclassify $3.5 million of the net unrealized gain as a decrease to interest expense. Accounting Standards Codification 820 ("Topic 820"), Fair Value Measurement and Disclosures, defines fair value and establishes a framework for measuring fair value. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 — quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 — observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 — unobservable inputs that are used when little or no market data is available. The fair values of the derivative financial instruments are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and observable inputs. The derivative financial instruments are classified within Level 2 of the valuation hierarchy. The following is a summary of assets and liabilities measured at fair value on a recurring basis: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements ​ Total Level 1 Level 2 Level 3 ​ ​ (In thousands) September 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivative financial instruments designated as effective hedges: ​ ​ ​ ​ Classified as assets in "Other assets, net" ​ $ 15,857 ​ ​ — ​ $ 15,857 ​ ​ — Classified as liabilities in "Other liabilities, net" ​ ​ 10,649 ​ — ​ ​ 10,649 ​ — Non-designated derivatives: ​ ​ ​ ​ Classified as assets in "Other assets, net" ​ 3,120 ​ — ​ 3,120 ​ — Classified as liabilities in "Other liabilities, net" ​ 3,104 ​ — ​ 3,104 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ Derivative financial instruments designated as effective hedges: ​ ​ ​ ​ Classified as assets in "Other assets, net" ​ $ 35,632 ​ ​ — ​ $ 35,632 ​ ​ — Classified as liabilities in "Other liabilities, net" ​ ​ 7,936 ​ — ​ ​ 7,936 ​ — Non-designated derivatives: ​ ​ ​ ​ Classified as assets in "Other assets, net" ​ 6,709 ​ — ​ 6,709 ​ — Classified as liabilities in "Other liabilities, net" ​ 6,508 ​ — ​ 6,508 ​ — ​ The fair values of our derivative financial instruments were determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of the derivative financial instrument. This analysis reflected the contractual terms of the derivative, including the period to maturity, and used observable market-based inputs, including interest rate market data and implied volatilities in such interest rates. While it was determined that the majority of the inputs used to value the derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the derivatives also utilized Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default. However, as of September 30, 2024 and December 31, 2023, the significance of the impact of the credit valuation adjustments on the overall valuation of the derivative financial instruments was assessed, and it was determined that these adjustments were not significant to the overall valuation of the derivative financial instruments. As a result, it was determined that the derivative financial instruments in their entirety should be classified in Level 2 of the fair value hierarchy. The net unrealized gains (losses) included in "Total other comprehensive income (loss)" in our statements of comprehensive loss for the three and nine months ended September 30, 2024 and 2023 were attributable to the net change in unrealized gains or losses related to effective derivative financial instruments that were outstanding during those periods, none of which were reported in our statements of operations as the derivative financial instruments were documented and qualified as hedging instruments. Realized and unrealized gains (losses) related to non-designated hedges are included in "Interest expense" in our statements of operations. Fair Value Measurements on a Nonrecurring Basis Our real estate assets are reviewed for impairment whenever there are changes in circumstances or indicators that the carrying amount of the assets may not be recoverable. This assessment resulted in the impairment of two development parcels, which had an estimated fair value of $24.7 million based on a market approach and were classified as Level 2 in the fair value hierarchy. The impairment loss totaled $18.2 million, which was included in "Impairment loss" in our statement of operations for the nine months ended September 30, 2024. Financial Assets and Liabilities Not Measured at Fair Value As of September 30, 2024 and December 31, 2023, all financial assets and liabilities were reflected in our balance sheets at amounts which, in our estimation, reasonably approximated their fair values, except for the following: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2024 ​ December 31, 2023 ​ Carrying ​ Carrying ​ ​ ​ Amount (1) ​ Fair Value ​ Amount (1) ​ Fair Value ​ (In thousands) Financial liabilities: ​ ​ ​ ​ Mortgage loans ​ $ 1,828,923 ​ $ 1,801,041 ​ $ 1,798,225 ​ $ 1,753,251 Revolving credit facility ​ 90,000 ​ 89,934 ​ 62,000 ​ 62,000 Term loans ​ 720,000 ​ 715,679 ​ 720,000 ​ 715,950 (1) The carrying amount consists of principal only. The fair values of the mortgage loans, revolving credit facility and term loans were determined using Level 2 inputs of the fair value hierarchy. The fair value of our mortgage loans is estimated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit profiles based on market sources. The fair value of our revolving credit facility and term loans is calculated based on the net present value of payments over the term of the facilities using estimated market rates for similar notes and remaining terms.

Segment Information
Segment Information	16. We review operating and financial data for each property on an individual basis; therefore, each of our individual properties is a separate operating segment. We define our reportable segments to be aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our CODM makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (multifamily, commercial, and third-party asset management and real estate services) based on the economic characteristics and nature of our assets and services. The CODM measures and evaluates the performance of our operating segments, with the exception of the third-party asset management and real estate services business, based on the net operating income ("NOI") of properties within each segment. NOI includes property rental revenue and parking revenue and deducts property operating expenses and real estate taxes. With respect to the third-party asset management and real estate services business, the CODM reviews revenue streams generated by this segment ("Third-party real estate services, including reimbursements"), as well as the expenses attributable to the segment ("General and administrative: third-party real estate services"), which are both disclosed separately in our statements of operations.

Commitments and Contingencies

Commitments and Contingencies
Commitments and Contingencies	17. Insurance We maintain general liability insurance with limits of $150.0 million per occurrence and in the aggregate, and property and rental value insurance coverage with limits of $1.0 billion per occurrence, with sub-limits for certain perils such as floods and earthquakes on each of our properties. We also maintain coverage, through our wholly owned captive insurance subsidiary, for a portion of the first loss on the above limits and for both conventional terrorist acts and for nuclear, biological, chemical or radiological terrorism events with limits of $2.0 billion per occurrence. These policies are partially reinsured by third-party insurance providers. We will continue to monitor the state of the insurance market, and the scope and costs of coverage for acts of terrorism. We cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for deductibles and losses in excess of the insurance coverage, which could be material. Our debt, consisting of mortgage loans secured by our properties, a revolving credit facility and term loans, contains customary covenants requiring adequate insurance coverage. Although we believe that we currently have adequate insurance coverage, we may not be able to obtain an equivalent amount of coverage at a reasonable cost in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance or refinance our properties. Construction Commitments As of September 30, 2024, we had an asset under construction that, based on our current plans and estimates, requires an additional $51.1 million to complete, which we anticipate will be primarily expended over the next year Environmental Matters Most of our assets have been subject, at some point, to environmental assessments that are intended to evaluate the environmental condition of the subject and surrounding assets. These environmental assessments generally have included a historical review, a public records review, a visual inspection of the site and surrounding assets, visual or historical evidence of underground storage tanks and other features, and the preparation and issuance of a written report. Soil, soil vapor and/or groundwater subsurface testing is conducted at our assets, when necessary, to further investigate any issues raised by the initial assessment that could reasonably be expected to pose a material concern to the property or result in us incurring material environmental liabilities as a result of redevelopment. The tests may not, however, have included extensive sampling or subsurface investigations. In each case where the environmental assessments have identified conditions requiring remedial actions required by law, we have initiated appropriate actions. The environmental assessments have not revealed any material environmental contamination that we believe would have a material adverse effect on our overall business, financial condition or results of operations, or that have not been anticipated and remediated during site redevelopment as required by law. Nevertheless, there can be no assurance that the identification of new areas of contamination, changes in the extent or known scope of contamination, the discovery of additional sites or changes in cleanup requirements would not result in significant cost to us. Environmental liabilities totaled $17.5 million and $17.6 million as of September 30, 2024 and December 31, 2023, and are included in "Other liabilities, net" in our balance sheets. Legal Proceedings In November 2023, the District of Columbia filed a lawsuit in the Superior Court of the District of Columbia alleging violations of its antitrust laws by RealPage, Inc., a seller of revenue management software products, and a number of large apartment community owners and operators, including JBG Associates, L.L.C., one of our subsidiaries. The lawsuit alleges collusion among the defendants to illegally fix and inflate the pricing of multifamily rents and seeks monetary damages, attorneys’ fees and costs, and injunctive relief. We believe there are defenses, both factual and legal, to the allegations in this proceeding, and we plan to vigorously defend the litigation. At this stage in the proceeding, it is not possible to predict any outcome or estimate the amount of loss, if any, which could be associated with any adverse decision. While we do not believe that these proceedings will have a material adverse effect on our financial condition, we cannot give assurance that the proceedings will not have a material effect on our results of operations or cash flows in the event of a negative outcome. There are various other legal actions against us in the ordinary course of business. In our opinion, the outcome of such matters will not have a material adverse effect on our financial condition, results of operations or cash flows. Other As of September 30, 2024, we had committed tenant-related obligations totaling $43.3 million ($43.2 million related to our consolidated entities and $126,000 related to our unconsolidated real estate ventures at our share). The timing and amounts of payments for tenant-related obligations are uncertain and may only be due upon satisfactory performance of certain conditions. From time to time, we (or ventures in which we have an ownership interest) have agreed, and may in the future agree with respect to unconsolidated real estate ventures, to (i) guarantee portions of the principal, interest and other amounts in connection with borrowings, (ii) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with borrowings, or (iii) provide guarantees to lenders and other third parties for the completion of development projects. We customarily have agreements with our outside venture partners whereby the partners agree to reimburse the real estate venture or us for their share of any payments made under certain of these guarantees. At times, we also have agreements with certain of our outside venture partners whereby we agree to either indemnify the partners and/or the associated ventures with respect to certain contingent liabilities associated with operating assets or to reimburse our partner for its share of any payments made by them under certain guarantees. Guarantees (excluding environmental) customarily terminate either upon the satisfaction of specified circumstances or repayment of the underlying debt. Amounts that we may be required to pay in future periods in relation to guarantees associated with budget overruns or operating losses are not estimable. As of September 30, 2024, we had additional capital commitments and certain recorded guarantees to our unconsolidated real estate ventures and other investments totaling $57.4 million. As of September 30, 2024, we had no debt principal payment guarantees related to our unconsolidated real estate ventures. ​ Additionally, with respect to borrowings of our consolidated entities, we may agree to (i) guarantee portions of the principal, interest and other amounts, (ii) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) or (iii) provide guarantees to lenders, tenants and other third parties for the completion of development projects. In connection with the Formation Transaction, we have an agreement with Vornado regarding tax matters (the "Tax Matters Agreement") that provides special rules that allocate tax liabilities if the distribution of JBG SMITH shares by Vornado, together with certain related transactions, is determined not to be tax-free. Under the Tax Matters Agreement, we may be required to indemnify Vornado against any taxes and related amounts and costs resulting from a violation by us of the Tax Matters Agreement.

Transactions with Related Parties
Transactions with Related Parties	18. Our third-party asset management and real estate services business provides fee-based real estate services to the JBG Legacy Funds and other third parties. In connection with the contribution to us of certain assets formerly owned by the JBG Legacy Funds as part of the Formation Transaction, the general partner and managing member interests in the JBG Legacy Funds that were held by certain former JBG executives (and who became members of our management team and/or Board of Trustees) were not transferred to us and remain under the control of these individuals. In addition, certain members of our senior management team and Board of Trustees have ownership interests in the JBG Legacy Funds, and own carried interests in each fund and in certain of our real estate ventures that entitle them to receive cash payments if the fund or real estate venture achieves certain return thresholds. During the second quarter of 2024, we combined our existing impact investing activities, including the Washington Housing Initiative ("WHI") formed with the Federal City Council in 2018, with the newly formed LEO Impact Capital ("LEO"), our workforce housing investment management platform. LEO aims to acquire, operate and preserve middle-income housing in rapidly growing neighborhoods vulnerable to rising housing costs. The WHI Impact Pool completed fundraising in 2020 with capital commitments totaling $114.4 million, which included a commitment from us of $11.2 million. As of September 30, 2024, our remaining unfunded commitment was $2.9 million. The third-party real estate services revenue, including expense reimbursements, from the JBG Legacy Funds and the WHI Impact Pool and its affiliates was $3.2 million and $10.3 million for the three and nine months ended September 30, 2024, and $4.8 million and $15.7 million for the three and nine months ended September 30, 2023. As of September 30, 2024 and December 31, 2023, we had receivables from the JBG Legacy Funds and the WHI Impact Pool and its affiliates totaling $2.3 million and $3.5 million for such services. Commencing in March 2023, in connection with the sale of an 80.0% interest in 4747 Bethesda Avenue in 2023, we leased our corporate offices from an unconsolidated real estate venture and incurred $1.3 million and $4.1 million of rent expense for the three and nine months ended September 30, 2024, and $1.6 million and $3.4 million of rent expense for the three and nine months ended September 30, 2023, which was included in "General and administrative expense" in our statements of operations. We have agreements with Building Maintenance Services ("BMS"), an entity in which we have a minor preferred interest, to supervise cleaning, engineering and security services at our properties. We paid BMS $2.5 million and $7.2 million for the three and nine months ended September 30, 2024, and $2.3 million and $7.0 million for the three and nine months ended September 30, 2023, which was included in "Property operating expenses" in our statements of operations.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements and notes are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not contain certain information required in annual financial statements and notes as required under GAAP. In our opinion, all adjustments considered necessary for a fair presentation have been included, and all such adjustments are of a normal recurring nature. All intercompany transactions and balances have been eliminated. The results of operations for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of the results that may be expected for a full year. These condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission ("SEC") on February 20, 2024 ("Annual Report"). The accompanying condensed consolidated financial statements include our accounts and those of our wholly owned subsidiaries and consolidated variable interest entities ("VIEs"), including JBG SMITH LP. See Note 5 for additional information. The portions of the equity and net income (loss) of consolidated entities that are not attributable to us are presented separately as amounts attributable to noncontrolling interests in our condensed consolidated financial statements. References to our financial statements refer to our unaudited condensed consolidated financial statements as of September 30, 2024 and December 31, 2023, and for the three and nine months ended September 30, 2024 and 2023. References to our balance sheets refer to our condensed consolidated balance sheets as of September 30, 2024 and December 31, 2023. References to our statements of operations refer to our condensed consolidated statements of operations for the three and nine months ended September 30, 2024 and 2023. References to our statements of comprehensive loss refer to our condensed consolidated statements of comprehensive loss for the three and nine months ended September 30, 2024 and 2023.
Income Taxes	Income Taxes We have elected to be taxed as a real estate investment trust ("REIT") under sections 856-860 of the Internal Revenue Code of 1986, as amended (the "Code"). Under those sections, a REIT which distributes at least 90% of its REIT taxable income as dividends to its shareholders each year and which meets certain other conditions will not be taxed on that portion of its taxable income which is distributed to its shareholders. We currently adhere and intend to continue to adhere to these requirements and to maintain our REIT status in future periods. We also participate in the activities conducted by our subsidiary entities that have elected to be treated as taxable REIT subsidiaries under the Code. As such, we are subject to federal, state and local taxes on the income from those activities.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Standards Not Yet Adopted Climate-Related Disclosures In March 2024, the SEC issued final rules on the enhancement and standardization of climate-related disclosures. The rules require disclosure of, among other things, (i) actual and potential material impacts of climate-related risks on our strategy, business model and outlook, (ii) climate-related targets and goals that have materially affected or are reasonably likely to materially affect our business, results of operations or financial condition, (iii) governance and management of climate-related risks and (iv) material Scope 1 and Scope 2 greenhouse gas emissions. Additionally, the rules require disclosures in the notes to the financial statements regarding the effects of severe weather events and other natural conditions, subject to certain materiality thresholds, and certain carbon offsets and renewable energy certificates. The rules are effective on a phased-in timeline beginning in the annual reports for the year ended December 31, 2025. In April 2024, the SEC announced a stay of these climate disclosure rules pending judicial review. We are currently evaluating the potential impact of adopting these new rules on our disclosures. Income Taxes In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("Topic 740"). Topic 740 modifies the rules on income tax disclosures to require entities to disclose (i) specific categories in the rate reconciliation, (ii) the income (loss) from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (iii) income tax expense or benefit from continuing operations (separated by federal, state and foreign). Topic 740 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. This guidance should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the potential impact of adopting this new guidance on our financial statement disclosures. Segment Reporting In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segments Disclosures" ("Topic 280"). Topic 280 enhances disclosures of significant segment expenses and other segment items regularly provided to the chief operating decision maker ("CODM"), extends certain annual disclosures to interim periods and permits more than one measure of segment profit (loss) to be reported under certain conditions. Topic 280 does not change the existing guidance on how a public entity identifies and determines its reportable segments. The amendments are effective in fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Retrospective adoption to all periods presented is required, and early adoption of the amendments is permitted. We are currently evaluating the potential impact of adopting this new guidance on our financial statement disclosures.
