1.Organization and Basis of Presentation

Organization

JBG SMITH Properties ("JBG SMITH"), a Maryland real estate investment trust ("REIT"), owns and operates a portfolio of commercial and multifamily assets amenitized with ancillary retail. JBG SMITH's portfolio reflects its longstanding strategy of owning and operating assets within Metro-served submarkets in the Washington, D.C. metropolitan area that have high barriers to entry and vibrant urban amenities. Over half of our portfolio is in National Landing in Northern Virginia, where we serve as the exclusive developer for Amazon.com, Inc.'s ("Amazon") new headquarters and where Virginia Tech's under-construction $1 billion Innovation Campus is located. In addition, our third-party asset management and real estate services business provides fee-based real estate services to the Washington Housing Initiative ("WHI") Impact Pool, Amazon, 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, 2021, JBG SMITH, as its sole general partner, controlled JBG SMITH LP and owned 90.8% of its common limited partnership units ("OP Units"). JBG SMITH is hereinafter referred to 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.

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, 2021, our Operating Portfolio consisted of 63 operating assets comprising 42 commercial assets totaling 13.1 million square feet (11.3 million square feet at our share) and 21 multifamily assets totaling 7,776 units (6,125 units at our share). Additionally, we have: (i) one under-construction multifamily asset with 808 units (808 units at our share); (ii) 11 near-term development assets totaling 5.3 million square feet (5.0 million square feet at our share) of estimated potential development density; and (iii) 25 future development assets totaling 14.3 million square feet (11.6 million square feet at our share) of estimated potential development density.

We derive our revenue primarily from leases with commercial and multifamily tenants, which 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.

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, 2021 and 2020 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, 2020, filed with the Securities and Exchange Commission.

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

10

information on our VIEs. 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.

Income Taxes

We have elected to be taxed as a 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 these activities.

2.Summary of Significant Accounting Policies

Significant Accounting Policies

There were no material changes to our significant accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

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 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. The most significant of these estimates include: (i) the underlying cash flows and holding periods used in assessing impairment of long-lived assets; (ii) the determination of useful lives for tangible and intangible assets; and (iii) the assessment of the collectability of receivables, including deferred rent receivables. Longer estimated holding periods for real estate assets directly reduce the likelihood of recording an impairment loss. If there is a change in the strategy for an asset or if market conditions dictate an earlier sale date, an impairment loss may be recognized, and such loss could be material.

In March 2020, the World Health Organization declared a global pandemic related to the novel coronavirus ("COVID-19"). The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the distribution, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. The ultimate adverse impact of COVID-19 is highly uncertain; however, the effects of COVID-19 on us and our tenants have affected estimates used in the preparation of the underlying cash flows used in assessing our long-lived assets for impairment and the assessment of the collectability of receivables from tenants, including deferred rent receivables. We have made what we believe to be appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent these estimates differ from actual results, our consolidated financial statements may be materially affected.

Due to the business disruptions and challenges caused by COVID-19, we have provided rent deferrals and other lease concessions to certain tenants. We have entered into agreements with certain tenants, many of which have been placed on the cash basis of accounting, resulting in the deferral to future periods or abatement of $492,000 of rent that had been contractually due in the third quarter of 2021. We are negotiating additional rent deferrals and other lease concessions with

11

some of our tenants, which have been considered when establishing credit losses against billed and deferred rent receivables. During 2020, we began recognizing revenue from substantially all co-working tenants and retailers except for grocers, pharmacies, essential businesses and certain national credit tenants on the cash basis of accounting.

Recent Accounting Pronouncements

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04, Reference Rate Reform ("Topic 848"). Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in Topic 848 is optional and may be elected over the period of March 12, 2020 through December 31, 2022 as reference rate reform activities occur. During the nine months ended September 30, 2021, we did not make any elections. During the year ended December 31, 2020, we elected to apply the hedge accounting expedients related to (i) the assertion that our hedged forecasted transactions remain probable and (ii) the assessments of effectiveness for future London Interbank Offered Rate ("LIBOR") indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves our past presentation of our derivatives. We will continue to evaluate the impact of the guidance and may apply other elections, as applicable.

3.Acquisition, Dispositions and Assets Held for Sale

Acquisition

We have agreed, subject to customary closing conditions, to acquire The Batley, a 432-unit multifamily asset in the Union Market submarket of Washington, D.C., for a purchase price of approximately $205 million. The building was 90.7% occupied as of September 30, 2021. We expect the acquisition to close in 2021. We intend to use The Batley as a replacement property in a like-kind exchange for the proceeds from the sale of Pen Place to Amazon, which is expected to close during the second quarter of 2022.

Dispositions

In April 2021, we invested cash in and contributed land to two real estate ventures and recognized an $11.3 million gain, which is included in "Gain on sale of real estate" in our statements of operations for the nine months ended September 30, 2021. See Note 4 for additional information.

During the three and nine months ended September 30, 2021, we recognized our proportionate share of the gain from the sale of various assets by our unconsolidated real estate ventures, which is included in "Income (loss) from unconsolidated real estate ventures, net" in our statements of operations. See Note 4 for additional information.

Assets Held for Sale

The amounts included in "Assets held for sale" in our balance sheets primarily represent the carrying value of real estate. The following is a summary of assets held for sale:

			Total	Assets Held

(1) Reflects our effective ownership interests in the underlying real estate as of September 30, 2021. We have multiple investments with certain venture partners with varying ownership interests in the underlying real estate.

(2) J.P. Morgan is the advisor for an institutional investor.

(3) As of September 30, 2021 and December 31, 2020, our total investments in unconsolidated real estate ventures were greater than the net book value of the underlying assets by $20.2 million and $18.9 million, resulting principally from capitalized interest and our zero investment balance in the real estate venture with CPPIB that owns 1101 17th Street.

In April 2021, we entered into two real estate ventures with an institutional investor advised by J.P. Morgan, in which we have 50% ownership interests, to design, develop, manage and own approximately 2.0 million square feet of new mixed-use development located in Potomac Yard, the southern portion of National Landing. Our venture partner contributed a land site that is entitled for 1.3 million square feet of development at Potomac Yard Landbay F, while we contributed cash and adjacent land with over 700,000 square feet of estimated development capacity at Potomac Yard Landbay G. We will also act as pre-developer, developer, property manager and leasing agent for all future commercial and residential properties on the site. We have determined the ventures are VIEs, but we are not the primary beneficiary of the VIEs and, accordingly, we have not consolidated either venture. We recognized an $11.3 million gain on the land contributed to one of the real estate ventures based on the cash received and the remeasurement of our retained interest in the asset, which was included in "Gain on sale of real estate" in our statements of operations for the nine months ended September 30, 2021. As part of the transaction, our venture partner elected to accelerate the monetization of a 2013 promote interest in the land contributed by it to the ventures. During the second quarter of 2021, the total amount of the promote paid was $17.5 million, of which $4.2 million was paid to certain of our non-employee trustees and certain of our executives.

The following is a summary of disposition activity by our unconsolidated real estate ventures for the nine months ended September 30, 2021:

A reconsideration event could cause us to consolidate an unconsolidated real estate venture in the future or deconsolidate a consolidated entity. We evaluate reconsideration events as we become aware of them. Reconsideration events include amendments to real estate venture agreements and changes in our partner's ability to make contributions to the venture. Under certain circumstances, we may purchase our partner's interest.

5.Variable Interest Entities

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, 2021 and December 31, 2020, we had interests in entities deemed to be VIEs. Although we are engaged to act as the managing partner in charge of 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, 2021 and December 31, 2020, the net carrying amount of our investment in these entities was $165.4 million and $116.2 million, which is included in "Investments in unconsolidated real estate ventures" in our balance sheets. Our equity in the income of unconsolidated VIEs is 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 90.8% 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 and hold our assets and liabilities through JBG SMITH LP, its total assets and liabilities comprise substantially all of our consolidated assets and liabilities.

Through the structure of the 1900 Crystal Drive transaction we executed in March 2021, we have the ability to facilitate an exchange out of an asset into 1900 Crystal Drive. We leased the land underlying 1900 Crystal Drive located in National

15

Landing to a lessee, which plans to construct an 808-unit multifamily asset comprising two towers with ground floor retail. The ground lessee has engaged us to be the development manager for the construction of 1900 Crystal Drive, and separately, we are the lessee in a master lease of the asset. We have an option to acquire the asset until a specified period after completion. In March 2021, the ground lessee entered into a mortgage loan collateralized by the leasehold interest with a maximum principal balance of $227.0 million and an interest rate of LIBOR plus 3.0% per annum. As of September 30, 2021, no proceeds had been received from the mortgage loan. In connection with the mortgage loan, we have guaranteed the completion of the asset and provided certain carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy). The ground lessee was obligated to invest $17.5 million of equity funding, all of which has been funded, and we are obligated to provide additional project funding through a mezzanine loan to the ground lessee, of which we have funded $11.7 million as of September 30, 2021. We determined that 1900 Crystal Drive is a VIE and that we are the primary beneficiary of the VIE. Accordingly, we consolidate the VIE with the lessee's ownership interest shown as "Noncontrolling interests" in our balance sheet. The ground lease, the mezzanine loan and the master lease described above are eliminated in consolidation. As of September 30, 2021, the VIE had total assets and liabilities of $29.7 million and $4.5 million. The assets of the VIE can only be used to settle the obligations of the VIE, and the liabilities include third-party liabilities of the VIE for which the creditors or beneficial interest holders do not have recourse against us.

(1) During 2020, we deposited $25.3 million with the Federal Communications Commission in connection with the acquisition of wireless spectrum licenses. In March 2021, we received the licenses. While the licenses are issued for ten years, as long as we act within the requirements and constraints of the regulatory authorities, the renewal and extension of these licenses is reasonably certain at minimal cost. Accordingly, we have concluded that the licenses are indefinite-lived intangible assets.

As of September 30, 2021 and December 31, 2020, the net carrying value of real estate collateralizing our mortgages payable totaled $1.8 billion. Our mortgages payable 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. Certain mortgages payable are recourse to us. See Note 17 for additional information.

In July 2021, we entered into a mortgage loan with a principal balance of $85.0 million, collateralized by 1225 S. Clark Street. The mortgage loan has a seven-year term and an interest rate of LIBOR plus 1.60% per annum.

As of September 30, 2021 and December 31, 2020, we had various interest rate swap and cap agreements on certain mortgages payable with an aggregate notional value of $1.3 billion. See Note 15 for additional information.

9.Redeemable Noncontrolling Interests

JBG SMITH LP

OP Units held by persons other than JBG SMITH are redeemable for cash or, at our election, our common shares, subject to certain limitations. During the nine months ended September 30, 2021 and 2020, unitholders redeemed 829,107 and 1.1 million OP Units, which we elected to redeem for an equivalent number of our common shares. As of September 30, 2021, outstanding OP Units totaled 13.1 million, representing a 9.2% ownership interest in JBG SMITH LP. On our balance sheets, our OP Units and certain vested long-term incentive partnership units ("LTIP Units") are presented at the higher of their redemption value or their carrying value, with adjustments to the redemption value recognized in "Additional paid-in capital." Redemption value per OP Unit is equivalent to the market value of one of our common shares at the end of the period. In October 2021, unitholders redeemed 20,953 OP Units, which we elected to redeem for an equivalent number of our common shares.

Consolidated Real Estate Venture

We are a partner in a consolidated real estate venture that owns a multifamily asset located in Washington, D.C. Pursuant to the terms of the real estate venture agreement, we are obligated to fund all capital contributions until our ownership interest reaches a maximum of 97.0%. Our partner can redeem its interest for cash under certain conditions. As of September 30, 2021, we held a 96.0% ownership interest in the real estate venture.

11.Share-Based Payments

LTIP Units and Time-Based LTIP Units

During the nine months ended September 30, 2021, we granted to certain employees 498,955 LTIP Units with time-based vesting requirements ("Time-Based LTIP Units") with a weighted average grant-date fair value of $29.21 per unit that

19

primarily vest ratably over four years subject to continued employment. Compensation expense for these units is being recognized over a four-year period.

Additionally, in January 2021, we granted 163,065 fully vested LTIP Units to certain employees, who elected to receive all or a portion of their cash bonus, related to 2020 service, as LTIP Units. The LTIP units had a grant-date fair value of $29.54 per unit. Compensation expense totaling $4.8 million for these LTIP Units was recognized in 2020.

In April 2021, as part of their annual compensation, we granted to non-employee trustees a total of 71,792 fully vested LTIP Units with an aggregate grant-date fair value of $1.9 million. The LTIP Units may not be sold while a trustee is serving on the Board of Trustees.

In July 2021, we granted to certain employees 608,325 Time-Based LTIP Units with a weighted average grant-date fair value of $31.73 per unit that vest 50% on the fifth anniversary of the grant date and 25% on each of the sixth and seventh anniversaries of the grant date, subject to continued employment. Compensation expense for these units is being recognized over a seven-year period.

The aggregate grant-date fair value of the Time-Based LTIP Units and LTIP Units granted during the nine months ended September 30, 2021 was $40.6 million. The Time-Based LTIP Units and LTIP Units were valued based on the closing common share price on the date of grant, less a discount for post-grant restrictions. The discount was determined using Monte Carlo simulations, and the following is a summary of the significant assumptions used to value these units:

Expected volatility	34.0% to 39.0%
Risk-free interest rate	0.1% to 0.4%
Post-grant restriction periods	2 to 3 years

Performance-Based LTIP Units

In January 2021, we granted to certain employees 627,874 LTIP Units with performance-based vesting requirements ("Performance-Based LTIP Units") with a weighted average grant-date fair value of $15.14 per unit. Our Performance-Based LTIP Units have a three-year performance period. 50% of any Performance-Based LTIP Units that are earned vest at the end of the three-year performance period and the remaining 50% vest on the fourth anniversary of the date of grant, subject to continued employment. If, however, the Performance-Based LTIP Units do not achieve a positive absolute total shareholder return ("TSR") at the end of the three-year performance period, but satisfy the relative performance criteria thereof, 50% of the units that otherwise could have been earned will be forfeited, and the remaining units that are earned will vest if and when we achieve a positive TSR during the succeeding seven years, measured at the end of each quarter. Compensation expense for these units is generally being recognized over a four-year period. In January 2021, the three-year performance period ended for the Performance-Based LTIP Units granted on February 2, 2018. Based on our relative performance and absolute TSR over the three-year performance period, 100% of the units granted were earned.

In July 2021, we granted to certain employees 844,070 Performance-Based LTIP Units with a weighted average grant-date fair value of $23.08 per unit that vest 50% on the fifth anniversary of the grant date and 25% on each of the sixth and seventh anniversaries of the grant date, subject to continued employment, and earn based on our achievement of four share price targets during the performance period commencing on the first anniversary of the grant date and ending on the sixth anniversary of the grant date. Compensation expense for these units is being recognized over a seven-year period.

The aggregate grant-date fair value of the Performance-Based LTIP Units granted during the nine months ended September 30, 2021 was $29.0 million, valued using Monte Carlo simulations. The following is a summary of the significant assumptions used to value the Performance-Based LTIP Units:

Expected volatility	31.0% - 34.0%
Dividend yield	2.6%
Risk-free interest rate	0.2% - 1.0%

20

Restricted Share Units ("RSUs")

In January 2021, we granted to certain non-executive employees 22,194 RSUs with time-based vesting requirements ("Time-Based RSUs") with a weighted average grant-date fair value of $31.52 per unit and 13,516 RSUs with performance-based vesting requirements ("Performance-Based RSUs") with a weighted average grant-date fair value of $15.16 per unit. Vesting requirements and compensation expense recognition for the Time-Based RSUs and the Performance-Based RSUs are identical to those of the Time-Based LTIP Units and Performance-Based LTIP Units granted in January 2021.

The aggregate grant-date fair value of the RSUs granted during the nine months ended September 30, 2021 was $905,000. The Time-Based RSUs were valued based on the closing common share price on the date of grant and the Performance-Based RSUs were valued using Monte Carlo simulations with the same significant assumptions used to value the Performance-Based LTIP Units above.

ESPP

Pursuant to the ESPP, employees purchased 34,320 common shares for $880,000 during the nine months ended September 30, 2021. The following is a summary of the significant assumptions used to value the ESPP common shares using the Black-Scholes model:

Expected volatility	39.0%
Dividend yield	1.5%
Risk-free interest rate	0.1%
Expected life	6 months

14.Shareholders' Equity and Earnings Per Common Share

Common Shares Repurchased

In March 2020, our Board of Trustees authorized the repurchase of up to $500 million of our outstanding common shares. During three and nine months ended September 30, 2021, we repurchased and retired 2.3 million and 2.9 million common shares for $68.9 million and $88.1 million, an average purchase price of $29.73 and $29.99 per share. During the three and nine months ended September 30, 2020, we repurchased and retired 1.4 million and 2.9 million common shares for $38.4 million and $79.6 million, an average purchase price of $26.64 and $27.82 per share. Since we began the share repurchase program, we have repurchased and retired 6.7 million common shares for $192.9 million, an average purchase price of $28.71 per share.

Earnings (Loss) Per Common Share

The following is a summary of the calculation of basic and diluted earnings (loss) per common share and a reconciliation of the amounts of net income (loss) available to common shareholders used in calculating basic and diluted earnings per common share to net income (loss):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2021		2020		X	2021		2020
	(In thousands, except per share amounts)
Net income (loss)	$	996	$	(25,005)		$	(26,391)	$	(17,093)
Net (income) loss attributable to redeemable noncontrolling interests		(103)		2,212			2,472		445
Net loss attributable to noncontrolling interests		—		—			1,108		—
Net income (loss) attributable to common shareholders		893		(22,793)			(22,811)		(16,648)
Distributions to participating securities		(763)		(822)			(1,497)		(1,729)
Net income (loss) available to common shareholders - basic and diluted	$	130	$	(23,615)		$	(24,308)	$	(18,377)
Weighted average number of common shares outstanding - basic and diluted		131,351		133,620			131,456		133,924
Earnings (loss) per common share - basic and diluted	$	0.00	$	(0.18)		$	(0.18)	$	(0.14)

The effect of the redemption of OP Units, LTIP Units and Time-Based LTIP Units that were outstanding as of September 30, 2021 and 2020 is excluded in the computation of diluted earnings 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 earnings per share). Since OP Units, LTIP Units and Time-Based LTIP Units, 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 OP Units, LTIP Units and Time-Based LTIP Unit impact are excluded from net income (loss) available to common shareholders and from the weighted average number of common shares outstanding in calculating diluted earnings per common share. Performance-Based LTIP Units, Special Performance-Based LTIP Units, Formation Awards and RSUs, which totaled 5.2 million and 4.9 million for the three and nine months ended September 30, 2021, and 4.4 million and 4.9 million for the three and nine months ended September 30, 2020, were excluded from the calculation of diluted earnings per common share as they were antidilutive, but potentially could be dilutive in the future.

Dividends Declared in October 2021

On October 27, 2021, our Board of Trustees declared a quarterly dividend of $0.225 per common share, payable on November 24, 2021 to shareholders of record as of November 10, 2021.

15.Fair Value Measurements

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. We do not enter into derivative financial instruments for speculative purposes.

As of September 30, 2021 and December 31, 2020, 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 loss on our derivative financial instruments designated as cash flow hedges was $27.8 million and $43.9 million as of September 30, 2021 and December 31, 2020 and was recorded in "Accumulated other comprehensive loss" in our balance sheets, of which a portion was reclassified to "Redeemable noncontrolling interests." Within the next 12 months, we expect to reclassify $14.6 million of net unrealized loss as an increase to interest expense.

23

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, 2021
Derivative financial instruments designated as cash flow hedges:
Classified as liabilities in "Other liabilities, net"	$	28,406		—	$	28,406		—
Derivative financial instruments not designated as cash flow hedges:
Classified as assets in "Other assets, net"		266		—		266		—
December 31, 2020
Derivative financial instruments designated as cash flow hedges:
Classified as liabilities in "Other liabilities, net"	$	44,222		—	$	44,222		—
Derivative financial instruments not designated as cash flow hedges:
Classified as assets in "Other assets, net"		35		—		35		—

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 under authoritative accounting guidance, 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, 2021 and December 31, 2020, 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 and losses included in "Other comprehensive income (loss)" in our statements of comprehensive income (loss) for the three and nine months ended September 30, 2021 and 2020 were attributable to the net change in unrealized gains or losses related to the interest rate swaps that were outstanding during those periods, none of which were reported in our statements of operations as the interest rate swaps were documented and qualified as hedging instruments.

24

Financial Assets and Liabilities Not Measured at Fair Value

As of September 30, 2021 and December 31, 2020, 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, 2021				December 31, 2020
	Carrying				Carrying
	Amount (1)		Fair Value		Amount (1)		Fair Value
	(In thousands)
Financial liabilities:
Mortgages payable	$	1,684,407	$	1,739,548	$	1,603,869	$	1,606,470
Unsecured term loans		400,000		400,201		400,000		399,678

(1) The carrying amount consists of principal only.

The fair values of the mortgages payable and unsecured term loans were determined using Level 2 inputs of the fair value hierarchy. The fair value of our mortgages payable 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 unsecured 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.

16.Segment Information

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 Chief Operating Decision Maker ("CODM"), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (commercial, multifamily, 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. The following represents the components of revenue from our third-party real estate services business:

	Three Months Ended September 30,					Nine Months Ended September 30,

(1) Estimated development fee revenue totaling $51.2 million as of September 30, 2021 is expected to be recognized over the next six years as unsatisfied performance obligations are completed.

(2) Represents reimbursement of expenses incurred by us on behalf of third parties, including allocated payroll costs and amounts paid to third-party contractors for construction management projects.

Management company assets primarily consist of management and leasing contracts with a net book value of $21.1 million and $25.5 million as of September 30, 2021 and December 31, 2020, which are classified in "Other assets, net" in our balance sheets. Consistent with internal reporting presented to our CODM and our definition of NOI, the third-party asset management and real estate services operating results are excluded from the NOI data below.

17.Commitments and Contingencies

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 $1.5 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 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 mortgages payable secured by our properties, a revolving credit facility and unsecured 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 reasonable costs 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, 2021, we had assets under construction that will, based on our current plans and estimates, require an additional $320.3 million to complete, which we anticipate will be primarily expended over the next three years. These capital expenditures are generally due as the work is performed, and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, issuance and sale of securities, and available cash.

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 assets. The environmental assessments did not reveal 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 $18.2 million as of September 30, 2021 and December 31, 2020 and are included in "Other liabilities, net" in our balance sheets.

Other

As of September 30, 2021, we had committed tenant-related obligations totaling $76.9 million ($73.6 million related to our consolidated entities and $3.3 million 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.

There are various 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.

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

28

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, 2021, we had additional capital commitments and certain recorded guarantees to our unconsolidated real estate ventures totaling $66.1 million. As of September 30, 2021, we had no principal payment guarantees related to our unconsolidated real estate ventures.

Additionally, with respect to borrowings of our consolidated entities, we have agreed, and may in the future 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. As of September 30, 2021, the aggregate amount of principal payment guarantees was $8.3 million for our consolidated entities.

18.Transactions with Related Parties

Our third-party asset management and real estate services business provides fee-based real estate services to the WHI, Amazon, the JBG Legacy Funds and other third parties. We provide services for the benefit of the JBG Legacy Funds that own interests in the assets retained by the JBG Legacy Funds. In connection with the contribution to us of the 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 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.

We launched the WHI with the Federal City Council in June 2018 as a scalable market-driven model that uses private capital to help address the scarcity of housing for middle income families. We are the manager for the WHI Impact Pool, which is the social impact debt financing vehicle of the WHI. As of September 30, 2021, the WHI Impact Pool had completed closings of capital commitments totaling $114.4 million, which included a commitment from us of $11.2 million. As of September 30, 2021, our remaining commitment was $8.3 million.

The third-party real estate services revenue, including expense reimbursements, from the JBG Legacy Funds and the WHI Impact Pool was $5.6 million and $17.2 million for the three and nine months ended September 30, 2021, and $4.6 million and $17.3 million for the three and nine months ended September 30, 2020. As of September 30, 2021 and December 31, 2020, we had receivables from the JBG Legacy Funds and the WHI Impact Pool totaling $3.5 million and $7.5 million for such services.

We rented our former corporate offices from an unconsolidated real estate venture and made payments totaling $246,000 and $1.0 million for the three and nine months ended September 30, 2021, and $403,000 and $4.1 million for the three and nine months ended September 30, 2020.

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 $4.9 million and $13.4 million during the three and nine months ended September 30, 2021, and $4.0 million and $12.6 million for the three and nine months ended September 30, 2020, which is included in "Property operating expenses" in our statements of operations.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Certain statements contained herein constitute forward-looking statements as such term is defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are not guarantees of future performance. They represent our intentions, plans, expectations and beliefs and are subject to numerous assumptions, risks and uncertainties. Our future results, financial condition and business may differ materially from those expressed in these forward-looking statements. You can find many of these statements by looking for words such as "approximates," "believes," "expects," "anticipates," "estimates," "intends," "plans," "would," "may" or other similar expressions in this Quarterly Report on Form 10-Q. Many of the factors that will determine the outcome of these and our other forward-looking statements are beyond our ability to control or predict. For further discussion of factors that could materially affect the outcome of our forward-looking statements, see "Risk Factors" in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2020 and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2020.

One of the most significant factors that could cause actual outcomes to differ materially from our forward-looking statements is the adverse effect of the current pandemic of the novel coronavirus ("COVID-19") on our financial condition, results of operations, cash flows, performance, tenants, the real estate market, and the global economy and financial markets. The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the distribution, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. Moreover, investors are cautioned to interpret many of the risks identified under the section titled "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 as being heightened as a result of the ongoing and numerous adverse impacts of COVID-19.

For these forward-looking statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. You are cautioned not to place undue reliance on our forward-looking statements, which speak only as of the date of this Quarterly Report on Form 10-Q. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to release publicly any revisions to our forward-looking statements to reflect events or circumstances occurring after the date of this Quarterly Report on Form 10-Q.

Organization and Basis of Presentation

JBG SMITH Properties ("JBG SMITH"), a Maryland real estate investment trust ("REIT"), owns and operates a portfolio of commercial and multifamily assets amenitized with ancillary retail. JBG SMITH's portfolio reflects its longstanding strategy of owning and operating assets within Metro-served submarkets in the Washington, D.C. metropolitan area that have high barriers to entry and vibrant urban amenities. Over half of our portfolio is in National Landing where we serve as the exclusive developer for Amazon.com, Inc.'s ("Amazon") new headquarters and where Virginia Tech's under-construction $1 billion Innovation Campus is located. In addition, our third-party asset management and real estate services business provides fee-based real estate services to the Washington Housing Initiative ("WHI") Impact Pool, Amazon, 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. JBG SMITH is referred to 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.

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."

References to our financial statements refer to our unaudited condensed consolidated financial statements as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. References to our balance sheets refer to our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. References to our statements of operations refer to our condensed consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020. References to our statements of cash flows refer to our condensed consolidated statements of cash flows for the nine months ended September 30, 2021 and 2020.

The accompanying financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), which requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and 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 these estimates.

We have elected to be taxed as a 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 these activities.

We aggregate our operating segments into three reportable segments (commercial, multifamily, and third-party asset management and real estate services) based on the economic characteristics and nature of our assets and services.

Our revenues and expenses are, to some extent, subject to seasonality during the year, which impacts quarterly net earnings, cash flows and funds from operations that affects the sequential comparison of our results in individual quarters over time. For instance, we have historically experienced higher utility costs in the first and third quarters of the year.

We compete with many property owners and developers. Our success depends upon, among other factors, trends affecting national and local economies, the financial condition and operating results of current and prospective tenants, the availability and cost of capital, interest rates, construction and renovation costs, taxes, governmental regulations and legislation, population trends, zoning laws, and our ability to lease, sublease or sell our assets at profitable levels. Our success is also subject to our ability to refinance existing debt on acceptable terms as it comes due.

Overview

As of September 30, 2021, our Operating Portfolio consisted of 63 operating assets comprising 42 commercial assets totaling 13.1 million square feet (11.3 million square feet at our share) and 21 multifamily assets totaling 7,776 units (6,125 units at our share). Additionally, we have: (i) one under-construction multifamily asset with 808 units (808 units at our share); (ii) 11 near-term development assets totaling 5.3 million square feet (5.0 million square feet at our share) of estimated potential development density; and (iii) 25 future development assets totaling 14.3 million square feet (11.6 million square feet at our share) of estimated potential development density. In 2021, we achieved carbon neutrality across our Operating Portfolio through the purchase of verified carbon offsets and renewable energy credits.

We continue to focus on our comprehensive plan to reposition our holdings in National Landing in Northern Virginia by executing a broad array of Placemaking strategies. Our Placemaking strategies include the delivery of new multifamily and office developments, locally sourced amenity retail, and thoughtful improvements to the streetscape, sidewalks, parks and other outdoor gathering spaces. In keeping with our dedication to Placemaking, each new project is intended to contribute to authentic and distinct neighborhoods by creating a vibrant street environment with robust retail offerings and other amenities including improved public spaces. We have also invested in Citizens Broadband Radio Service ("CBRS") wireless spectrum in National Landing as part of our efforts to make National Landing among the first 5G-operable submarkets in the nation.

In November 2018, Amazon announced it had selected sites that we own in National Landing as the location of its new headquarters. We currently have leases with Amazon totaling approximately 1.0 million square feet at six office buildings

31

in National Landing. In March 2019, we executed purchase and sale agreements with Amazon for two of our National Landing development sites, Metropolitan Park and Pen Place, which will serve as the initial phase of construction associated with Amazon's new headquarters at National Landing. In January 2020, we sold Metropolitan Park to Amazon for $155.0 million and began constructing two new office buildings thereon, totaling 2.1 million square feet, inclusive of over 50,000 square feet of street-level retail with new shops and restaurants. We are the developer, property manager and retail leasing agent for Amazon's new headquarters at National Landing.

2021 Outlook

A fundamental component of our strategy to maximize long-term net asset value per share is active capital allocation. Since our inception in 2017, we have completed the sale, recapitalization and/or ground lease of $1.7 billion of primarily office assets, and we intend to opportunistically sell at least another $1.4 billion of non-core office assets and land. We are currently targeting dispositions primarily of office assets in submarkets where we have less concentration and where we anticipate lower growth rates going forward relative to other opportunities within our portfolio. Additionally, we may market select land assets where ground lease or joint venture execution may represent the clearest path to maximizing value. Redeploying the proceeds from any such sales and recapitalizations will not only help fund our planned growth but will also further advance the strategic shift of our portfolio to majority multifamily.

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic and recommended containment and mitigation measures worldwide. On March 13, 2020, a National Emergency was declared in the United States in response to COVID-19. The efforts made by federal, state and local governments to mitigate the spread of COVID-19 included orders requiring the temporary closure of or imposed limitations on the operations of certain non-essential businesses, which adversely affected many tenants, especially tenants in the retail industry.

The pandemic continues to evolve, and while we are optimistic about the future, we remain cautious about the medium-term implications for office assets. Vacancy is still at record highs across the region, and most companies are still not fully back in the office. Occupancy of our commercial portfolio declined by 180 basis points from June 30, 2021, the majority of which was related to pre-pandemic decision making, although we had two civilian agency Government Services Administration tenants that reduced their leased square footage due to a planned shift toward working from home. We expect continued pressure on our office occupancy through the end of the year and into 2022. Although parking revenue increased during the three months ended September 30, 2021 as compared to the same period in 2020, parking revenue in our commercial portfolio was approximately 60% below pre-pandemic levels of approximately $30 million annually due to delayed return-to-the-office plans for many of our office tenants.

We are seeing improvements in our multifamily portfolio, with a 390 basis point increase in the occupancy of our operating multifamily portfolio from June 30, 2021 and an increase in market rents due to increased demand and limited new supply.

The significance, extent and duration of the impact of COVID-19 on our business remains largely uncertain and dependent on future developments that cannot be accurately predicted at this time. These developments include: the continued severity, duration, transmission rate and geographic spread of COVID-19 in the United States, the continued speed of the vaccine distribution, the effectiveness and willingness of people to take COVID-19 vaccines, the duration of associated immunity and the efficacy of vaccines against variants of COVID-19, the extent and effectiveness of other containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in areas in which we operate, as containment measures continue to be lifted, and whether the residential market in the Washington, D.C. region and any of our properties will be materially impacted by the moratoriums on residential evictions, among others. These uncertainties make it difficult to predict operating results for our business for 2021. Therefore, we could experience material declines in revenue, net income, NOI and/or Funds from Operations ("FFO"). For more information, see "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Additionally, investing and financing activity during the nine months ended September 30, 2021 included:

● the lease of the land underlying 1900 Crystal Drive located in National Landing to a lessee, which plans to construct an 808-unit multifamily asset comprising two towers with ground floor retail. Through the structure of the 1900 Crystal Drive transaction, we have the ability to facilitate an exchange out of an asset into 1900 Crystal Drive. The ground lessee has engaged us to be the development manager for the construction of 1900 Crystal Drive, and separately, we are the lessee in a master lease of the asset. We have an option to acquire the asset until a specified period after completion. See Note 5 to the financial statements for additional information;

● an investment in two real estate ventures, in which we have 50% ownership interests, to design, develop, manage and own approximately 2.0 million square feet of new mixed-use development located in Potomac Yard, the southern portion of National Landing. We recognized an $11.3 million gain on the land contributed to one of the real estate ventures based on the cash received and the remeasurement of our retained interest in the asset.

* Not meaningful.

Property rental revenue increased by approximately $7.2 million, or 6.1%, to $125.9 million in 2021 from $118.7 million in 2020. The increase was primarily due to (i) a $5.1 million increase related to the deferral of rent and the write-off of deferred rent receivables for tenants that were placed on the cash basis of accounting in 2020 and a decrease in uncollectable operating lease receivables attributable to COVID-19 in 2021, (ii) a $4.7 million increase related to 4747 Bethesda Avenue,

34

West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (iii) a $2.6 million increase related to 1770 Crystal Drive, which was placed into service in the fourth quarter of 2020, and (iv) a $1.8 million increase related to the commencement of the lease with Amazon at 2100 Crystal Drive. The increase in property rental revenue was partially offset by a $6.4 million decrease related to lower occupancy at the Universal Buildings, 2011 Crystal Drive, 2101 L Street and RTC-West.

Third-party real estate services revenue, including reimbursements, decreased by approximately $1.1 million, or 4.2%, to $25.8 million in 2021 from $27.0 million in 2020. The decrease was primarily due to a $2.0 million decrease in reimbursements revenue, a $705,000 decrease in other service revenue and a $584,000 decrease in construction management fees, partially offset by a $1.4 million increase in development fee revenue primarily related to the timing of development projects and a $736,000 increase in leasing fees.

Depreciation and amortization expense increased by approximately $245,000, or 0.4%, to $56.7 million in 2021 from $56.5 million in 2020. The increase was primarily due to (i) a $1.9 million increase related to 2345 Crystal Drive due to an increase in tenant improvements, (ii) a $1.7 million increase related to 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, and (iii) a $924,000 increase due to 1770 Crystal Drive being placed into service. The increase in depreciation and amortization expense was partially offset by a $4.0 million decrease related to 2000 South Bell Street and 2001 South Bell Street as we commenced construction on two new buildings in 2021.

Property operating expense increased by approximately $2.6 million, or 7.0%, to $40.2 million in 2021 from $37.6 million in 2020. The increase was primarily due to (i) a $1.2 million increase related to 2451 Crystal Drive for costs incurred for construction management services provided to tenants, (ii) an $885,000 increase related to 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (iii) a $576,000 increase due to 1770 Crystal Drive being placed into service and (iv) $535,000 related to 2221 South Clark Street due to higher operating expenses. The increase in property operating expense was partially offset by a $1.5 million decrease related to 1901 South Bell Street due to costs incurred in 2020 for construction management services provided to tenants.

Real estate tax expense increased by approximately $905,000, or 5.2%, to $18.3 million in 2021 from $17.4 million in 2020. The increase was primarily due to a $548,000 increase related to 4747 Bethesda Avenue and The Wren as these properties placed additional space into service, and a $543,000 increase related to 5 M Street Southwest due to an increase in its applicable tax rate in 2021.

General and administrative expense: corporate and other increased by approximately $1.0 million, or 9.2%, to $12.1 million in 2021 from $11.1 million in 2020. The increase was primarily due to a decrease in capitalizable payroll costs related to development projects.

General and administrative expense: third-party real estate services decreased by approximately $2.7 million, or 9.4%, to $25.5 million in 2021 from $28.2 million in 2020. The decrease was primarily due to a decrease in reimbursable expenses.

General and administrative expense: share-based compensation related to Formation Transaction and special equity awards decreased by approximately $3.7 million, or 51.2%, to $3.5 million in 2021 from $7.1 million in 2020. The decrease was primarily due to the graded vesting of certain awards issued in prior years, which resulted in lower expense as portions of the awards vested.

Transaction and other costs of $3.0 million in 2021 primarily included $1.4 million of demolition costs related to 2000 South Bell Street and 2001 South Bell Street and $1.4 million of expenses related to completed, potential and pursued transactions. Transaction and other costs of $845,000 in 2020 consisted of $406,000 of integration and severance costs, $260,000 of expenses related to completed, potential and pursued transactions, and $179,000 of demolition costs related to 223 23rd Street and 2300 Crystal Drive.

Income from unconsolidated real estate ventures increased by approximately $21.5 million to $20.5 million for 2021 from a loss of $965,000 in 2020. The increase was primarily due to the recognition of our proportionate share of the gain from the sale of 500 L'Enfant Plaza of $23.1 million. The increase in income from unconsolidated real estate ventures was

35

partially offset by a $1.4 million impairment of our investment in an unconsolidated real estate venture due to a decrease in the value of the underlying asset.

Interest expense increased by approximately $358,000, or 2.1%, to $17.2 million in 2021 from $16.9 million in 2020. The increase was primarily due to a $1.3 million decrease in capitalized interest primarily due to the placing of additional space into service at 4747 Bethesda Avenue, West Half, The Wren, 901 W Street and 1770 Crystal Drive, and a $293,000 increase due to a new mortgage loan at 1225 S. Clark Street. The increase in interest expense was partially offset by a $1.2 million decrease related to the repayment of a mortgage loan at WestEnd25 in 2020.

Comparison of the Nine Months Ended September 30, 2021 to 2020

Property rental revenue increased by approximately $16.4 million, or 4.6%, to $371.0 million in 2021 from $354.5 million in 2020. The increase was primarily due to (i) a $12.8 million increase related to 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (ii) an $11.1 million increase due to the deferral of rent and the write-off of deferred rent receivable for tenants that were placed on the cash basis of accounting in 2020 and a decrease in uncollectable operating lease receivables attributable to COVID-19, (iii) a $7.4 million increase related to 1770 Crystal Drive, which was placed into service in the fourth quarter of 2020, (iv) a $3.9 million increase related to 1225 S. Clark Street due to the commencement of a lease and (v) a $3.2 million increase related to the additional space leased by Amazon at 2345 Crystal Drive. The increase in property rental revenue was partially offset by (i) a $14.1 million decrease related to lower occupancy at the Universal Buildings, 2011 Crystal Drive, 2101 L Street and RTC-West, (ii) a $4.2 million decrease related to RiverHouse Apartments and The Bartlett due to increased rent concessions and lower market rents, and (iii) a $3.4 million decrease related to 1901 South Bell Street due to tenant reimbursements for construction services in 2020.

Third-party real estate services revenue, including reimbursements, increased by approximately $6.8 million, or 8.1%, to $90.7 million in 2021 from $83.9 million in 2020. The increase was primarily due to a $14.2 million increase in development fees related to the timing of development projects. The increase in third-party real estate services revenue was partially offset by a $3.8 million decrease in reimbursements revenue, a $1.7 million decrease in property and asset management fees due to the sale of assets within the JBG Legacy Funds and a $1.7 million decrease in construction management fees due to the timing of construction projects.

Depreciation and amortization expense increased by approximately $20.5 million, or 13.0%, to $178.1 million in 2021 from $157.6 million in 2020. The increase was primarily due to (i) an $8.1 million increase related to 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (ii) a $6.8 million increase related to the Universal Buildings due to the write-off of certain tenant improvements, (iii) a $6.0 million increase related to 2345 Crystal Drive due to an increase in tenant improvements, (iv) a $2.5 million increase due to 1770

36

Crystal Drive being placed into service, (v) a $1.5 million increase related to 1550 Crystal Drive as additional space was placed into service and (vi) a $1.3 million increase related to RTC-West due to the acceleration of depreciation of certain assets. The increase in depreciation and amortization expense was partially offset by a $5.1 million decrease related to 2000 South Bell Street and 2001 South Bell Street as we commenced construction on two new buildings in 2021.

Property operating expense increased by approximately $4.1 million, or 3.8%, to $109.9 million in 2021 from $105.9 million in 2020. The increase was primarily due to (i) a $3.3 million increase related to 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (ii) a $2.8 million increase related to 2451 Crystal Drive due to costs incurred for construction management services provided to tenants, (iii) a $1.4 million increase due to 1770 Crystal Drive being placed into service and (iv) an $832,000 increase at Courthouse Plaza 1 and 2 related to ground rent expense. The increase in property operating expense was partially offset by a $4.3 million decrease related to 1901 South Bell Street due to costs incurred in 2020 for construction management services provided to tenants.

Real estate tax expense increased by approximately $1.7 million, or 3.2%, to $55.1 million in 2021 from $53.4 million in 2020. The increase was primarily due to (i) a $1.8 million increase at 4747 Bethesda Avenue, West Half, The Wren, 900 W Street and 901 W Street as these properties placed additional space into service, (ii) a $701,000 increase related to 5 M Street Southwest due to an increase in its applicable tax rate in 2021 and (iii) an increase of $533,000 due to 1770 Crystal Drive being placed into service. The increase in real estate tax expense was partially offset by a decrease in real estate tax assessments for various properties located in National Landing.

General and administrative expense: corporate and other increased by approximately $997,000, or 2.7%, to $38.5 million in 2021 from $37.5 million in 2020. The increase was primarily due to a decrease in capitalizable payroll costs related to development projects.

General and administrative expense: third-party real estate services decreased by approximately $6.2 million, or 7.2%, to $80.0 million in 2021 from $86.3 million in 2020. This decrease was primarily due to a decrease in reimbursable expenses and a decrease in share-based compensation expense.

General and administrative expense: share-based compensation related to Formation Transaction and special equity awards decreased by approximately $12.6 million, or 49.4%, to $12.9 million in 2021 from $25.4 million in 2020. The decrease was primarily due to the graded vesting of certain awards issued in prior years, which resulted in lower expense as portions of the awards vested.

Transaction and other costs of $8.9 million in 2021 consisted of $5.4 million of expenses related to completed, potential and pursued transactions, $2.9 million of demolition costs related to 2000 South Bell Street and 2001 South Bell Street and $616,000 of integration and severance costs. Transaction and other costs of $7.5 million in 2020 primarily included $4.0 million of costs related to a charitable commitment to the Washington Housing Conservancy, a non-profit that acquires and owns affordable workforce housing in the Washington, D.C. metropolitan area, and $3.1 million of integration and severance costs.

Income from unconsolidated real estate ventures increased by approximately $40.7 million, or 237.2%, to $23.5 million for 2021 from a loss of $17.1 million in 2020. The increase was primarily due to (i) the recognition of our proportionate share of the gain from the sale of various assets totaling $28.3 million as compared to a $3.0 million loss from the sale of Woodglen in 2020 and (ii) a $6.5 million impairment charge recognized in 2020 related to our investment in a venture that owned The Marriott Wardman Park hotel, and $2.7 million for losses incurred from its COVID-19 related closure. The increase in income from unconsolidated real estate ventures was partially offset by a $1.4 million impairment of our investment in an unconsolidated real estate venture due to a decrease in the value of the underlying asset.

Interest expense increased by approximately $5.7 million, or 12.7%, to $50.3 million in 2021 from $44.7 million in 2020. The increase was primarily due to a $6.7 million decrease in capitalized interest primarily due to the placing of additional space into service at 4747 Bethesda Avenue, West Half, The Wren, 901 W Street and 1770 Crystal Drive and a $5.7 million increase due to new mortgage loans entered into in 2020 at 1221 Van Street, The Bartlett and 220 20^th Street. The increase was also due to higher average outstanding balances under our unsecured term loans. The increase in interest expense was

37

partially offset by a lower outstanding balance under our revolving credit facility and a $3.6 million decrease related to the repayment of a mortgage loan at WestEnd25 in 2020.

Gain on the sale of real estate of $11.3 million in 2021 was based on the cash received and the remeasurement of our retained interest in the land we contributed to one of our unconsolidated real estate ventures. See Note 4 to the financial statements for additional information. Gain on the sale of real estate of $59.5 million in 2020 was due to the sale of Metropolitan Park.

FFO

FFO is a non-GAAP financial measure computed in accordance with the definition established by the National Association of Real Estate Investment Trusts ("NAREIT") in the NAREIT FFO White Paper - 2018 Restatement. NAREIT defines FFO as net income (loss) (computed in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity, including our share of such adjustments for unconsolidated real estate ventures.

We believe FFO is a meaningful non-GAAP financial measure useful in comparing our levered operating performance from period-to-period and as compared to similar real estate companies because FFO excludes real estate depreciation and amortization expense and other non-comparable income and expenses, which implicitly assumes that the value of real estate diminishes predictably over time rather than fluctuating based on market conditions. FFO does not represent cash generated from operating activities and is not necessarily indicative of cash available to fund cash requirements and should not be considered as an alternative to net income (loss) (computed in accordance with GAAP) as a performance measure or cash flow as a liquidity measure. FFO may not be comparable to similarly titled measures used by other companies.

The following is the reconciliation of net income (loss) attributable to common shareholders, the most directly comparable GAAP measure, to FFO:

	Three Months Ended September 30,					Nine Months Ended September 30,

(1) Related to decreases in the value of the underlying assets.

NOI and Same Store NOI

NOI is a non-GAAP financial measure management uses to assess a segment's performance. The most directly comparable GAAP measure is net income (loss) attributable to common shareholders. We use NOI internally as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only property related revenue (which includes base rent, tenant reimbursements and other operating revenue, net

38

of free rent and payments associated with assumed lease liabilities) less operating expenses and ground rent, if applicable. NOI also excludes deferred rent, related party management fees, interest expense, and certain other non-cash adjustments, including the accretion of acquired below-market leases and the amortization of acquired above-market leases and below-market ground lease intangibles. Management uses NOI as a supplemental performance measure of our assets and believes it provides useful information to investors because it reflects only those revenue and expense items that are incurred at the asset level, excluding non-cash items. In addition, NOI is considered by many in the real estate industry to be a useful starting point for determining the value of a real estate asset or group of assets. However, because NOI excludes depreciation and amortization and captures neither the changes in the value of our assets that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our assets, all of which have real economic effect and could materially impact the financial performance of our assets, the utility of NOI as a measure of the operating performance of our assets is limited. NOI presented by us may not be comparable to NOI reported by other REITs that define these measures differently. We believe to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income (loss) attributable to common shareholders as presented in our financial statements. NOI should not be considered as an alternative to net income (loss) attributable to common shareholders as an indication of our performance or to cash flows as a measure of liquidity or our ability to make distributions.

During the three months ended September 30, 2021, our same store pool decreased to 55 properties from 56 properties due to the exclusion of 500 L'Enfant Plaza, which was sold by an unconsolidated real estate venture during the period. During the nine months ended September 30, 2021, our same store pool increased from 52 properties to 55 properties due to the inclusion of 1800 South Bell Street, F1RST Residences, 1221 Van Street and the commercial portion of 2221 S. Clark Street, and the exclusion of Fairway Apartments, which was sold during the period. Information provided on a same store basis includes the results of properties that are owned, operated and in-service for the entirety of both periods being compared, which excludes properties for which significant redevelopment, renovation or repositioning occurred during either of the periods being compared. While there is judgment surrounding changes in designations, a property is removed from the same store pool when the property is considered to be under-construction because it is undergoing significant redevelopment or renovation pursuant to a formal plan or is being repositioned in the market and such renovation or repositioning is expected to have a significant impact on property NOI. A development property or under-construction property is moved to the same store pool once a substantial portion of the growth expected from the development or redevelopment is reflected in both the current and comparable prior year period. Acquisitions are moved into the same store pool once we have owned the property for the entirety of the comparable periods and the property is not under significant development or redevelopment.

Same store NOI remained at $72.7 million for the three months ended September 30, 2021 compared to the same period in 2020. Same Store NOI was positively impacted by a decrease in uncollectable operating lease receivables and rent deferrals, which was offset by lower occupancy in our commercial portfolio, and lower rents and higher concessions for certain of our multifamily assets.

Same store NOI decreased $7.7 million, or 3.3%, to $223.3 million for the nine months ended September 30, 2021 from $231.0 million for the same period in 2020. The decrease was substantially attributable to the COVID-19 pandemic, which commenced at the end of the first quarter of 2020, including (i) higher concessions and lower rents in our multifamily portfolio and (ii) lower occupancy and a decline in parking revenue in our commercial portfolio. These declines were partially offset by a decrease in cleaning expenses across our commercial portfolio.

Reportable Segments

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 defined our reportable segments to be aligned with our method of internal reporting and the way our Chief Executive Officer, who is also our Chief Operating Decision Maker ("CODM"), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (commercial, multifamily, and third-party asset management and real estate services) based on the economic characteristics and nature of our assets and services.

40

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 NOI of properties within each segment.

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. The following represents the components of revenue from our third-party real estate services business:

See discussion of third-party real estate services revenue, including reimbursements, and third-party real estate services expenses for the three and nine months ended September 30, 2021 in the preceding pages under "Results of Operations."

Consistent with internal reporting presented to our CODM and our definition of NOI, the third-party asset management and real estate services operating results are excluded from the NOI data below.

41

Property revenue is calculated as property rental revenue plus parking revenue. Property expense is calculated as property operating expenses plus real estate taxes. Consolidated NOI is calculated as property revenue less property expense. See Note 16 to the financial statements for the reconciliation of net income (loss) attributable to common shareholders to consolidated NOI for the three and nine months ended September 30, 2021 and 2020. The following is a summary of NOI by segment:

Comparison of the Three Months Ended September 30, 2021 to 2020

Commercial: Property rental revenue increased by $3.0 million, or 3.2%, to $96.0 million in 2021 from $93.1 million in 2020. Consolidated NOI increased by $2.7 million, or 4.9%, to $56.9 million in 2021 from $54.2 million in 2020. The increase in property revenue and consolidated NOI was due to (i) a decline in rent deferrals and uncollectable operating lease receivables related to tenants impacted by COVID-19, (ii) increases related to 1770 Crystal Drive as the property was placed into service, and (iii) increases related to 2100 Crystal Drive, 1225 South Clark Street and 2345 Crystal Drive due to higher occupancy. These increases were partially offset by a decrease related to the Universal Buildings and 2101 L Street due to lower occupancy.

Multifamily: Property rental revenue increased by $4.6 million, or 15.1%, to $35.1 million in 2021 from $30.5 million in 2020. Consolidated NOI increased by $3.3 million, or 26.5%, to $16.0 million in 2021 from $12.6 million in 2020. The increase in property revenue and consolidated NOI was due to The Wren, 900 W Street, 901 W Street and West Half as these properties placed additional units into service. These increases were partially offset by lower rents and higher concessions at RiverHouse Apartments and 2221 South Clark Street.

Comparison of the Nine Months Ended September 30, 2021 to 2020

Commercial: Property rental revenue increased by $8.1 million, or 2.9%, to $284.9 million in 2021 from $276.8 million in 2020. Consolidated NOI increased by $11.1 million, or 6.8%, to $172.7 million in 2021 from $161.7 million in 2020. The increase in property revenue and consolidated NOI was due to (i) a decline in rent deferrals and uncollectable operating lease receivables related to tenants impacted by COVID-19, (ii) increases in revenues related to 4747 Bethesda Avenue and 1770 Crystal Drive as these properties were placed into service, and (iii) increases related to 2100 Crystal Drive, 1225 South Clark Street and 2345 Crystal Drive due to higher occupancy. These increases were partially offset by a decrease in parking revenue due to reduced transient and office parking and decreases related to the Universal Buildings, 2101 L Street and RTC-West due to lower occupancy.

42

Multifamily: Property rental revenue increased by $5.5 million, or 5.8%, to $100.6 million in 2021 from $95.1 million in 2020. Consolidated NOI increased by $125,000, or 0.3%, to $46.9 million in 2021 from $46.8 million in 2020. The increase in property revenue and consolidated NOI was due to The Wren, 900 W Street, 901 W Street and West Half as these properties placed additional units into service. These increases were partially offset by lower rents and higher concessions at RiverHouse Apartments and The Bartlett.

Liquidity and Capital Resources

Property rental income is our primary source of operating cash flow and is dependent on many factors including occupancy levels and rental rates, as well as our tenants' ability to pay rent. In addition, our third-party asset management and real estate services business provides fee-based real estate services to the WHI, Amazon, the JBG Legacy Funds and other third parties. Our assets provide a relatively consistent level of cash flow that enables us to pay operating expenses, debt service, recurring capital expenditures, dividends to shareholders and distributions to holders of OP Units. Other sources of liquidity to fund cash requirements include proceeds from financings, recapitalizations, asset sales and the issuance and sale of securities. We anticipate that cash flows from continuing operations and proceeds from financings, recapitalizations and asset sales, together with existing cash balances, will be adequate to fund our business operations, debt amortization, capital expenditures, any dividends to shareholders and distributions to holders of OP Units over the next 12 months.

Financing Activities

The following is a summary of mortgages payable:

	Weighted Average
	Effective
	Interest Rate (1)	September 30, 2021		December 31, 2020

Mortgages payable, net		$	1,674,285	$	1,593,738

(1) Weighted average effective interest rate as of September 30, 2021.

(2) Includes variable rate mortgages payable with interest rate cap agreements.

(3) Includes variable rate mortgages payable with interest rates fixed by interest rate swap agreements.

(4) As of September 30, 2021, net deferred financing costs related to an unfunded mortgage loan totaling $4.0 million were included in "Other assets, net."

As of September 30, 2021 and December 31, 2020, the net carrying value of real estate collateralizing our mortgages payable totaled $1.8 billion. Our mortgages payable 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. Certain mortgages payable are recourse to us. See Note 17 to the financial statements for additional information.

In July 2021, we entered into a mortgage loan with a principal balance of $85.0 million, collateralized by 1225 S. Clark Street. The mortgage loan has a seven-year term and an interest rate of LIBOR plus 1.60% per annum.

As of September 30, 2021 and December 31, 2020, we had various interest rate swap and cap agreements on certain mortgages payable with an aggregate notional value of $1.3 billion. See Note 15 to the financial statements for additional information.

43

Credit Facility

As of September 30, 2021 and December 31, 2020, our $1.4 billion credit facility consisted of a $1.0 billion revolving credit facility maturing in January 2025, a $200.0 million unsecured term loan ("Tranche A-1 Term Loan") maturing in January 2023 and a $200.0 million unsecured term loan ("Tranche A-2 Term Loan") maturing in July 2024. The following is a summary of amounts outstanding under the credit facility:

	Effective
	Interest Rate (1)	September 30, 2021		December 31, 2020
		(In thousands)
Revolving credit facility (2) (3) (4)	1.13%	$	—	$	—

Unsecured term loans			400,000		400,000
Unamortized deferred financing costs, net			(1,507)		(2,021)
Unsecured term loans, net		$	398,493	$	397,979

(1) Effective interest rate as of September 30, 2021.

(2) As of September 30, 2021 and December 31, 2020, letters of credit with an aggregate face amount of $1.4 million and $1.5 million were outstanding under our revolving credit facility.

(3) As of September 30, 2021 and December 31, 2020, net deferred financing costs related to our revolving credit facility totaling $5.4 million and $6.7 million were included in "Other assets, net."

(4) The interest rate for our revolving credit facility excludes a 0.15% facility fee.

(5) As of September 30, 2021 and December 31, 2020, the outstanding balance was fixed by interest rate swap agreements. The interest rate swaps mature concurrently with the respective term loan and provide a weighted average interest rate of 1.39% for the Tranche A-1 Term Loan and 1.34% for the Tranche A-2 Term Loan.

Our existing floating rate debt instruments, including our credit facility, with a principal balance totaling $1.6 billion and our hedging arrangements with a notional value totaling $1.7 billion currently use as a reference rate the U.S. dollar London Interbank Offered Rate ("LIBOR"), and we expect a transition from LIBOR to another reference rate due to plans to phase out the reference rate by the end of 2021, after which point its continuation cannot be assured. Though an alternative reference rate for LIBOR, the Secured Overnight Financing Rate ("SOFR"), exists, significant uncertainties still remain. We can provide no assurance regarding the future of LIBOR and when our LIBOR-based instruments will transition from LIBOR as a reference rate to SOFR or another reference rate. The discontinuation of a benchmark rate or other financial metric, changes in a benchmark rate or other financial metric, or changes in market perceptions of the acceptability of a benchmark rate or other financial metric, including LIBOR, could, among other things, result in increased interest payments, changes to our risk exposures, or require renegotiation of previous transactions. In addition, any such discontinuation or changes, whether actual or anticipated, could result in market volatility, adverse tax or accounting effects, increased compliance, legal and operational costs, and risks associated with contract negotiations.

Common Shares Repurchased

In March 2020, our Board of Trustees authorized the repurchase of up to $500 million of our outstanding common shares. During three and nine months ended September 30, 2021, we repurchased and retired 2.3 million and 2.9 million common shares for $68.9 million and $88.1 million, an average purchase price of $29.73 and $29.99 per share. During the three and nine months ended September 30, 2020, we repurchased and retired 1.4 million and 2.9 million common shares for $38.4 million and $79.6 million, an average purchase price of $26.64 and $27.82 per share. Since we began the share repurchase program, we have repurchased and retired 6.7 million common shares for $192.9 million, an average purchase price of $28.71 per share.

Purchases under the program are made either in the open market or in privately negotiated transactions from time to time as permitted by federal securities laws and other legal requirements. The timing, manner, price and amount of any repurchases will be determined by us at our discretion and will be subject to economic and market conditions, share price,

44

applicable legal requirements and other factors. The program may be suspended or discontinued at our discretion without prior notice.

Liquidity Requirements

Our principal liquidity needs for the next 12 months and beyond include:

● normal recurring expenses;

● debt service and principal repayment obligations, including balloon payments on maturing debt;

● capital expenditures, including major renovations, tenant improvements and leasing costs;

● development expenditures;

● dividends to shareholders and distributions to holders of OP Units;

● common share repurchases; and

● acquisitions of properties, either directly or indirectly through the acquisition of equity interests therein.

We expect to satisfy these needs using one or more of the following:

● cash and cash equivalent balances;

● cash flows from operations;

● distributions from real estate ventures; and

● proceeds from financings, recapitalizations and asset sales.

While we do not expect the need to do so during the next 12 months, we also can issue securities to raise funds.

While we have not experienced a significant impact to date in this regard, we expect COVID-19 to continue to have an adverse impact on our liquidity and capital resources. Future decreases in cash flows from operations resulting from tenant defaults, rent deferrals or decreases in our rents or occupancy, would decrease the cash available for the capital uses described above.

As of September 30, 2021, we had $998.6 million of availability under our credit facility (net of outstanding letters of credit totaling $1.4 million). As of September 30, 2021, we had no debt on a consolidated basis and at our share scheduled to mature in 2021.

Contractual Obligations and Commitments

During the nine months ended September 30, 2021, there were no material changes to the contractual obligation information presented in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2020.

As of September 30, 2021, we had additional capital commitments and certain recorded guarantees to our unconsolidated real estate ventures totaling $66.1 million.

As of September 30, 2021, we had committed tenant-related obligations totaling $76.9 million ($73.6 million related to our consolidated entities and $3.3 million 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.

We launched the WHI with the Federal City Council in June 2018 as a scalable market-driven model that uses private capital to help address the scarcity of housing for middle income families. We are the manager for the WHI Impact Pool, which is the social impact debt financing vehicle of the WHI. As of September 30, 2021, the WHI Impact Pool had

45

completed closings of capital commitments totaling $114.4 million, which included a commitment from us of $11.2 million. As of September 30, 2021, our remaining commitment was $8.3 million.

On October 27, 2021, our Board of Trustees declared a quarterly dividend of $0.225 per common share.

Summary of Cash Flows

The following summary discussion of our cash flows is based on our statements of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows:

	Nine Months Ended September 30,
	2021		2020
	(In thousands)
Net cash provided by operating activities	$	154,412	$	127,855
Net cash used in investing activities		(96,751)		(57,696)
Net cash (used in) provided by financing activities		(91,820)		280,038

Cash Flows for the Nine Months Ended September 30, 2021

Cash and cash equivalents, and restricted cash decreased $34.2 million to $229.2 million as of September 30, 2021, compared to $263.3 million as of December 31, 2020. This decrease resulted from $91.8 million of net cash used in financing activities and $96.8 million of net cash used in investing activities, partially offset by $154.4 million of net cash provided by operating activities. Our outstanding debt was $2.1 billion and $2.0 billion as of September 30, 2021 and December 31, 2020.

Net cash provided by operating activities of $154.4 million primarily comprised: (i) $147.7 million of net income (before $185.4 million of non-cash items and $11.3 million gain on sale of real estate), (ii) $13.2 million of return on capital from unconsolidated real estate ventures and (iii) $6.5 million of net change in operating assets and liabilities. Non-cash income adjustments of $185.4 million primarily include depreciation and amortization expense, share-based compensation expense, net income from unconsolidated real estate ventures, deferred rent and amortization of lease incentives.

Net cash used in investing activities of $96.8 million comprised: (i) $108.4 million of development costs, construction in progress and real estate additions, (ii) $32.7 million of investments in unconsolidated real estate ventures and other, and (iii) $10.3 million of deposits for real estate and other acquisitions, partially offset by (iv) $40.2 million of distributions of capital from unconsolidated real estate ventures and (v) $14.4 million of proceeds from the sale of real estate.

Net cash used in financing activities of $91.8 million primarily comprised: (i) $88.9 million of dividends paid to common shareholders, (ii) $82.3 million of common shares repurchased, (iii) $13.7 million of distributions to redeemable noncontrolling interests, (iv) $5.7 million of debt issuance costs, and (v) $4.5 million of repayments of mortgages payable, partially offset by (vi) $85.0 million of borrowings under mortgages payable and (vii) $17.5 million of contributions from noncontrolling interests.

Off-Balance Sheet Arrangements

Unconsolidated Real Estate Ventures

We consolidate entities in which we have a controlling interest or are the primary beneficiary in a variable interest entity. From time to time, we may have off-balance-sheet unconsolidated real estate ventures and other unconsolidated arrangements with varying structures.

As of September 30, 2021, we have investments in unconsolidated real estate ventures totaling $486.1 million. For these investments, we exercise significant influence over but do not control these entities and, therefore, account for these investments using the equity method of accounting. For a more complete description of our real estate ventures, see Note 4 to the financial statements.

46

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, 2021, we had additional capital commitments and certain recorded guarantees to our unconsolidated real estate ventures totaling $66.1 million. As of September 30, 2021, we had no principal payment guarantees related to our unconsolidated real estate ventures.

A reconsideration event could cause us to consolidate an unconsolidated real estate venture in the future or deconsolidate a consolidated entity. We evaluate reconsideration events as we become aware of them. Reconsideration events include amendments to real estate venture agreements and changes in our partner's ability to make contributions to the venture. Under certain circumstances, we may purchase our partner's interest.

Commitments and Contingencies

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 $1.5 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 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 mortgages payable secured by our properties, a revolving credit facility and unsecured 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 reasonable costs 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, 2021, we had assets under construction that will, based on our current plans and estimates, require an additional $320.3 million to complete, which we anticipate will be primarily expended over the next three years. These capital expenditures are generally due as the work is performed, and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, issuance and sale of securities, and available cash.

Other

As of September 30, 2021, we had committed tenant-related obligations totaling $76.9 million ($73.6 million related to our consolidated entities and $3.3 million related to our unconsolidated real estate ventures at our share). The timing and

47

amounts of payments for tenant-related obligations are uncertain and may only be due upon satisfactory performance of certain conditions.

There are various 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.

With respect to borrowings of our consolidated entities, we have agreed, and may in the future 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. As of September 30, 2021, the aggregate amount of principal payment guarantees was $8.3 million for our consolidated entities.

Environmental Matters

Under various federal, state and local laws, ordinances and regulations, an owner of real estate is liable for the costs of removal or remediation of certain hazardous or toxic substances on such real estate. These laws often impose such liability without regard to whether the owner knew of, or was responsible for, the presence of such hazardous or toxic substances. The costs of remediation or removal of such substances may be substantial and the presence of such substances, or the failure to promptly remediate such substances, may adversely affect the owner's ability to sell such real estate or to borrow using such real estate as collateral. In connection with the ownership and operation of our assets, we may be potentially liable for such costs. The operations of current and former tenants at our assets have involved, or may have involved, the use of hazardous materials or generated hazardous wastes. The release of such hazardous materials and wastes could result in us incurring liabilities to remediate any resulting contamination. The presence of contamination or the failure to remediate contamination at our properties may (i) expose us to third-party liability (e.g., for cleanup costs, natural resource damages, bodily injury or property damage), (ii) subject our properties to liens in favor of the government for damages and costs the government incurs in connection with the contamination, (iii) impose restrictions on the manner in which a property may be used or which businesses may be operated, or (iv) materially adversely affect our ability to sell, lease or develop the real estate or to borrow using the real estate as collateral. In addition, our assets are exposed to the risk of contamination originating from other sources. While a property owner may not be responsible for remediating contamination that has migrated onsite from an identifiable and viable offsite source, the contaminant's presence can have adverse effects on operations and the redevelopment of our assets. To the extent we send contaminated materials to other locations for treatment or disposal, we may be liable for cleanup of those sites if they become contaminated.

Most of our assets have been subject, at some point, to environmental assessments that are intended to evaluate the environmental condition of the 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 the preparation and issuance of a written report. Soil 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. They 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 did not reveal 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. As disclosed in Note 17 to the financial statements, environmental liabilities totaled $18.2 million as of September 30, 2021 and December 31, 2020 and are included in "Other liabilities, net" in our balance sheets.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have exposure to fluctuations in interest rates, which are sensitive to many factors that are beyond our control. The following is a summary of our annual exposure to a change in interest rates:

	September 30, 2021						December 31, 2020
			Weighted						Weighted
			Average		Annual				Average
			Effective		Effect of 1%				Effective
			Interest		Change in				Interest
	Balance		Rate		Base Rates		Balance		Rate
	(Dollars in thousands)
Debt (contractual balances):
Mortgages payable:
Variable rate (1)	$	762,246		2.08%	$	7,728	$	678,346	2.18%
Fixed rate (2)		922,161		4.32%		—		925,523	4.32%

Credit facility:

Pro rata share of debt of unconsolidated real estate ventures (contractual balances):
Variable rate (1)	$	281,752		2.57%	$	2,857	$	319,057	2.47%
Fixed rate (2)		83,707		4.46%		—		79,989	4.36%
	$	365,459			$	2,857	$	399,046

(1) Includes variable rate mortgages payable with interest rate cap agreements.

(2) Includes variable rate mortgages payable with interest rates fixed by interest rate swap agreements.

(3) The interest rate for our revolving credit facility excludes a 0.15% facility fee.

(4) As of September 30, 2021 and December 31, 2020, the outstanding balance was fixed by interest rate swap agreements. The interest rate swaps mature concurrently with the term loan and provide a weighted average interest rate of 1.39% for the Tranche A-1 Term Loan and 1.34% for the Tranche A-2 Term Loan.

The fair value of our mortgages payable 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 unsecured 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. As of September 30, 2021 and December 31, 2020, the estimated fair value of our consolidated debt was $2.1 billion and $2.0 billion. These estimates of fair value, which are made at the end of the reporting period, may be different from the amounts that may ultimately be realized upon the disposition of our financial instruments.

Hedging Activities

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. We do not enter into derivative financial instruments for speculative purposes.

Derivative Financial Instruments Designated as Cash Flow Hedges

Certain derivative financial instruments, consisting of interest rate swap and cap agreements, are designated as cash flow hedges, and are carried at their estimated fair value on a recurring basis. We assess the effectiveness of our cash flow hedges

49

both at inception and on an ongoing basis. If the hedges are deemed to be effective, the fair value is recorded in “Accumulated other comprehensive loss” in our balance sheets and is subsequently reclassified into "Interest expense" in our statements of operations in the period that the hedged forecasted transactions affect earnings. Our cash flow hedges become less than perfectly effective if the critical terms of the hedging instrument and the forecasted transactions do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and interest rates. In addition, we evaluate the default risk of the counterparty by monitoring the creditworthiness of the counterparty. While management believes its judgments are reasonable, a change in a derivative's effectiveness as a hedge could materially affect expenses, net income and equity.

As of September 30, 2021 and December 31, 2020, we had interest rate swap agreements with an aggregate notional value of $862.7 million, which were designated as cash flow hedges. The fair value of our interest rate swaps designated as cash flow hedges consisted of liabilities totaling $28.4 million and $44.2 million as of September 30, 2021 and December 31, 2020, included in "Other liabilities, net" in our balance sheets.

Derivative Financial Instruments Not Designated as Hedges

Certain derivative financial instruments, consisting of interest rate swap and cap agreements, are considered economic hedges, but not designated as accounting hedges, and are carried at their estimated fair value on a recurring basis. Realized and unrealized gains are recorded in "Interest expense" in our statements of operations in the period in which the change occurs. As of September 30, 2021 and December 31, 2020, we had various interest rate cap agreements with an aggregate notional value of $867.7 million, which were not designated as cash flow hedges. The fair value of our interest rate caps not designated as hedges consisted of assets totaling $266,000 and $35,000 as of September 30, 2021 and December 31, 2020, included in "Other assets, net" in our balance sheets.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of September 30, 2021, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are, from time to time, involved in legal actions arising in the ordinary course of business. In our opinion, the outcome of such matters is not expected to have a material adverse effect on our financial position, results of operations or cash flows.

ITEM 1A. RISK FACTORS

There have been no material changes to the risk factors previously disclosed in our Annual Report for the year ended December 31, 2020, filed with the SEC on February 23, 2021.

No. of LTIP Units Awarded:
Grant Date:	July 29, 2021

RECITALS

A.The Employee is an employee of JBG SMITH Properties, a Maryland real estate investment trust (the “Company”) and provides services to JBG SMITH Properties LP, a Delaware limited partnership, through which the Company conducts substantially all of its operations (the “Partnership”).

B.In accordance with the JBG SMITH Properties 2017 Omnibus Share Plan, as it may be amended from time to time (the “Plan”), the Company desires, in connection with the employment of the Employee, to provide the Employee with an opportunity to acquire LTIP Units (as defined in the agreement of limited partnership of the Partnership, as amended (the “Partnership Agreement”)) having the rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption and conversion set forth herein, in the Plan and in the Partnership Agreement, and thereby provide additional incentive for the Employee to promote the progress and success of the business of the Company, the Partnership and its Subsidiaries. Upon the close of business on the Grant Date pursuant to this Performance LTIP Unit Agreement (this “Agreement”), the Employee shall receive the number of LTIP Units specified above (the “Award LTIP Units”), subject to the restrictions and conditions set forth herein, in the Plan and in the Partnership Agreement.

C.The exact number of LTIP Units earned under this award (the “Award”) shall be determined based on the achievement of certain share price hurdles during the Performance Period, as provided herein. Any LTIP Units not earned at the conclusion of the Performance Period will be forfeited.

NOW, THEREFORE, the Company, the Partnership and the Employee agree as follows:

1.Definitions. Capitalized terms used herein without definitions shall have the meanings given to those terms in the Plan. In addition, as used herein:

2

forth in reasonable detail the basis of the event (provided such notice must be given to the Company within 30 days of the Employee becoming aware of such condition).

“Securities Act” means the Securities Act of 1933, as amended.

2.Effectiveness of Award. The Employee shall be admitted as a partner of the Partnership with beneficial ownership of the Award LTIP Units as of the Grant Date by (i) signing and delivering to the Partnership a copy of this Agreement and (ii) signing, as a Limited Partner, and delivering to the Partnership a counterpart signature page to the Partnership Agreement (attached hereto as Exhibit A). Upon execution of this Agreement by the Employee, the Partnership and the Company, the books and records of the Partnership shall reflect the issuance to the Employee of the Award LTIP Units. Thereupon, the Employee shall have all the rights of a Limited Partner of the Partnership with respect to a number of LTIP Units equal to the Award LTIP Units, as set forth in the Partnership Agreement, subject, however, to the restrictions and conditions specified in Section 3 below.

3.Vesting and Earning of Award LTIP Units.

(a)This Award is subject to performance vesting during the Performance Period and service vesting tied to Continuous Service of the Employee thereafter as specified herein.  The Award LTIP Units will be subject to forfeiture based on the Company’s failure to achieve the Hurdle Price Level for a consecutive twenty (20) trading day period during the Performance Period, as set forth in this Section 3, subject to Section 5 hereof in the event of a Change in Control.

3

(b)The number of Award LTIP Units earned will be determined based on the Closing Price over any consecutive twenty (20) trading day period being equal to or greater than the Hurdle Price Levels set forth below.  The date or dates on which such criteria are achieved (which date or dates shall be the twentieth (20^th) consecutive trading day on which such Hurdle Price Level is met) are the “Hurdle Date” or “Hurdle Dates.”

Hurdle Price Level	Percentage of Award LTIP Units Earned (in incremental amounts)
$35	17.5%
$40	22.5%
$45	27.5%
$50	32.5%

The Award will be forfeited in its entirety if the Closing Price fails to reach $35 over a consecutive twenty (20) trading day period during the Performance Period.  For the avoidance of doubt, once a Hurdle Date for a Hurdle Price Level is achieved, the applicable percentage of Award LTIP Units will be earned regardless of whether the Closing Price later falls below such Hurdle Price Level and further provided that Employee can only earn Award LTIP Units once per Hurdle Price Level.  For example, if Shares attain a Closing Price over twenty (20) consecutive trading days of $35, then 17.5% of the Award LTIPs will be considered to have been earned.  No additional Award LTIP Units will be considered to have been earned unless and until the Shares attain a Closing Price over twenty (20) consecutive trading days of $40, at which time an additional 22.5% of the Award LTIP Units will be considered to have been earned.  For the avoidance of doubt, any Award LTIP Units that become earned will be subject to the requirements to remain in Continuous Service through the dates set forth in Section 3(d) below to become vested.

(c)As soon as practicable following the achievement of each Hurdle Date hereunder, if any, the Committee shall:

(i)determine the number of LTIP Units earned by the Employee, which number will be rounded up to the nearest whole number of LTIP Units  (the “Earned Award LTIP Units”), provided that the Employee may not earn more than the number of LTIP Units granted except as set forth in (c)(ii) immediately below.

(ii)determine the number of additional LTIP Units that would have accumulated if the Employee had received all distributions paid by the Partnership from the Grant Date with respect to the Earned LTIP Units determined pursuant to clause (i) (reduced by the distributions actually paid with respect to such Earned Award LTIP Units) and such distributions had been invested in Common Units at a price equal to the fair market value of one Common Unit on the ex-dividend date (referred to as “Distribution Equivalent LTIP Units” and together with the Earned Award LTIP Units determined pursuant to clause (i), the “Earned LTIP Unit Equivalents”). Notwithstanding the foregoing, unless the Committee specifically resolves to issue Distribution Equivalent LTIP Units, the value of the unpaid distributions determined pursuant to the preceding sentence will be paid in cash.  Accordingly, the Earned LTIP Unit Equivalents shall refer only to the Earned Award LTIP

4

Units determined pursuant to clause (i).  The Grant Date of any Distribution Equivalent LTIP Units shall be the date on which the Committee makes the determination provided for in this clause (ii), and the initial Economic Capital Account Balance of the Distribution Equivalent LTIP Units as of the Grant Date thereof shall be zero (0).  The Distribution Equivalent LTIP Units shall be subject to the vesting set forth in Section 3(d) below.  The issuance of the Distribution Equivalent LTIP Units will be subject to the Employee confirming the truth and accuracy of the representations set forth in Section 13 hereof and executing and delivering such documents, comparable to the documents executed and delivered in connection with this Agreement, as the Company and/or the Partnership reasonably request in order to comply with all applicable legal requirements, including, without limitation, federal and state securities laws.

If, at the conclusion of the Performance Period, the number of Earned LTIP Unit Equivalents is smaller than the number of Award LTIP Units previously issued to the Employee, then the Employee, as of the conclusion of the Performance Period, shall forfeit a number of Award LTIP Units equal to the difference without payment of any consideration by the Partnership; thereafter the term Award LTIP Units will refer only to the Earned Award LTIP Units (and any Distribution Equivalent LTIP Units) and neither the Employee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in the LTIP Units that were so forfeited.

(d)If any of the Award LTIP Units have been earned based on performance as provided in Section 3(b), subject to Section 4  and Section 5 hereof, the Earned LTIP Unit Equivalents shall become vested in the following amounts and at the following times, provided that the Continuous Service of the Employee continues through and on the applicable vesting date or the accelerated vesting date provided in Section 4  or Section 5 hereof, as applicable:

(i)On the fifth anniversary of the Grant Date, the lesser of (i) 50% of the Award LTIP Units, and (ii) the Earned LTIP Unit Equivalents shall become vested;

(ii)Following the fifth anniversary of the Grant Date and up to and including the sixth anniversary of the Grant Date, any additional Earned LTIP Unit Equivalents shall become immediately vested subject to the condition that the total vested Earned LTIP Unit Equivalents do not exceed 50% of the Award LTIP Units;

(iii)On the sixth anniversary of the Grant Date, the lesser of (i) 75% of the Award LTIP Units, and (ii) the Earned LTIP Unit Equivalents shall become vested; and

(iv)On the seventh anniversary of the Grant Date, the balance of the Earned LTIP Unit Equivalents shall become vested (each of (i) through (iv), a “Vesting Period”).

(e)Any Award LTIP Units that do not become vested pursuant to Section 3(d),Section 4  or Section 5 hereof shall, without payment of any consideration by the Partnership, automatically and without notice be forfeited and be and become null and void, and neither the Employee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such unvested Award LTIP Units.

4.Termination of Employee’s Service Relationship; Death and Disability.

5

(a)If the Employee is a party to a Service Agreement that addresses treatment of the Award LTIP Units on a termination of employment and ceases to be an employee of the Company or any of its affiliates, the provisions of such Service Agreement that apply to the Award LTIP Unit will govern, provided, however, that this Agreement will govern, solely to determine the number of Award LTIP Units that become vested and not as it pertains to any defined terms, if a Service Agreement provides more favorable treatment than the treatment specified in 4(b)(A) or 4(b)(B). If the Employee is not a party to a Service Agreement that addresses treatment of the Award LTIP Unit on a termination of employment, Sections 4(b) through 4(c) hereof shall govern the treatment of the Employee’s Award LTIP Units exclusively. In the event an entity ceases to be a subsidiary or affiliate of the Company or the Partnership, such action shall be deemed to be a termination of employment of all employees of that entity for purposes of this Agreement, provided that the Committee or the Board, in its sole and absolute discretion, may make provision in such circumstances for lapse of forfeiture restrictions and/or accelerated vesting of some or all of the Employee’s remaining unvested Award LTIP Units that have not previously been forfeited, effective immediately prior to such event.

(b)In the event of a termination of the Employee’s Continuous Service by (A) the Employer without Cause after the one-year anniversary of the Grant Date, (B) the Employee for Good Reason after the one-year anniversary of the Grant Date, (C) the Employee’s Retirement after the one-year anniversary of the Grant Date, (D) the Employee’s death, or (E) the Employee’s Disability (each, a “Qualified Termination”), the Employee will not forfeit the Award LTIP Units upon such termination, and, instead, the Employee’s Earned LTIP Unit Equivalents shall become vested upon such termination and, notwithstanding anything in this Agreement to the contrary, the Employee’s Award LTIP Units shall remain outstanding for the remainder of the Performance Period such that Employee shall remain eligible to earn additional Earned LTIP Unit Equivalents, which additional Earned LTIP Unit Equivalents, if any, shall become vested upon the determination in Section 3(c).

(c)In the event of a termination of the Employee’s Continuous Service other than a Qualified Termination, all Award LTIP Units except for those that, as of the date at such termination, both (i) have ceased to be subject to forfeiture pursuant to Sections 3(b) and (c) hereof and (ii) are vested pursuant to Section 3(d) hereof shall, without payment of any consideration by the Partnership, automatically and without notice terminate, be forfeited and be and become null and void, and neither the Employee nor any of his or her successors, heirs, assigns, or personal representatives will thereafter have any further rights or interests in such Award LTIP Units.

5.Change in Control.

(a)If a Change in Control occurs on or prior to the sixth anniversary of the Grant Date, subject to the Employee’s Continuous Service through the consummation of such Change in Control, the Committee shall, prior to the consummation of the Change in Control, determine whether the intent, economic opportunity and economic value of the Award LTIP Units are capable of being replicated at least at the same level as in effect prior to the Change in Control:  

(i) If the Committee determines that the intent, economic opportunity and economic value of the Award LTIP Units are not capable of being replicated at least at the same level as in effect prior to the Change in Control, (i) the Performance Period shall end as of immediately prior to

the Change in Control, (ii) the provisions of Section 3 shall apply to determine the Earned LTIP Unit Equivalents except that if the Change in Control is a Transactional Change in Control, the fair value, as determined by the Committee, of the total consideration paid or payable in the transaction resulting in the Transactional Change of Control for one Share shall be used to determine if any incremental Award LTIP Units become earned, and the determination shall be made based on such price per Share without regard to the price over the preceding trading days, (iii) the Earned LTIP Unit Equivalents, as well as any Award LTIP Units that previously became Earned LTIP Unit Equivalents, shall become fully vested immediately prior to the consummation of such Change in Control, and (iv) any Award LTIP Units that do not become earned shall be forfeited.

(ii) If the Committee determines that the intent, economic opportunity and economic value of the Award LTIP Units are capable of being replicated at least at the same level as in effect prior to the Change in Control, the Performance Period shall not end as of immediately prior to the Change in Control and the Award LTIP Units shall continue with appropriate adjustments to the Hurdle Price Levels as the Committee deems appropriate.

(b)Notwithstanding anything herein to the contrary, if a Change in Control occurs on or before the first anniversary of the Grant Date, the Award LTIP Units shall be immediately forfeited without payment.

(c)Subject to Section 5(a)(i) (which provides for immediate vesting) and Section 5(d), the Award LTIP Units and Earned LTIP Unit Equivalents determined under Section 3 shall remain subject to satisfaction of the Hurdle Price Levels and vesting tied to Continuous Employment as provided in Section 3(d), as applicable, except that the Employee shall become fully vested in the Earned LTIP Unit Equivalents if he is terminated without Cause or resigns for Good Reason within 18 months following the Change in Control.

(d)Notwithstanding anything in this Agreement to the contrary, including, without limitation, the Committee’s determination in Section 5(a)(i) above, if (a) the Employee holds Earned LTIP Unit Equivalents as of immediately prior to a Change in Control, (b) the Earned LTIP Unit Equivalents are not continued, assumed or substituted in connection with such Change in Control, and (c) the Employee remains in employment as of immediately prior to the consummation of such Change in Control, then the Earned LTIP Unit Equivalents shall vest in full and become convertible into LTIP Units and non-forfeitable as of immediately prior to the consummation of the Change in Control.  The Earned LTIP Unit Equivalents shall be considered “assumed” or “substituted” for purposes of the preceding sentence only if each of the following requirements is satisfied, as determined by the Committee, as constituted immediately before the Change in Control, in its sole discretion: (i) the contractual obligations represented by the Earned LTIP Unit Equivalents are expressly assumed (and not simply by operation of law) by the successor entity or its parent in connection with the Change in Control with appropriate adjustments to the number and type of securities of the successor entity or its parent subject to the converted or substituted award which at least preserves the compensation element of the Earned LTIP Unit Equivalents existing at the time of the Change in Control; (ii) in the case of a substituted award, it must be of the same type of award and have the same tax

7

consequences to the Employee as the Earned LTIP Unit Equivalents; (iii) the vesting terms of the converted or substituted award (including with respect to accelerated vesting upon certain terminations of employment) must be substantially identical to the terms of the Earned LTIP Unit Equivalents; (iv) the converted or substituted award must be convertible or redeemable into another security that is itself convertible or redeemable into shares of a publicly traded company, each in a manner substantially identical to the corresponding terms of the Earned LTIP Unit Equivalents; and (v) all the other terms and conditions of the converted or substituted award must be no less favorable to the Employee than the terms of the Earned LTIP Unit Equivalents (including the provisions that would apply in the event of a subsequent Change in Control).

6.Distribution Participation Date and LTIP Unit Initial Sharing Percentage.

(a)The holder of the Award LTIP Units shall be entitled to receive distributions and allocations with respect to such Award LTIP Units to the extent provided for in the Partnership Agreement, including Exhibit E thereof, as modified hereby.

(b)The Distribution Participation Date with respect to such Award LTIP Units shall be the applicable Hurdle Date.  Accordingly, for the avoidance of doubt, from the Grant Date until the applicable  Distribution Participation Date, the holder of the Award LTIP Units shall only be entitled to certain distributions and allocations described in, and pursuant to, Sections 2.A. and 3 of Exhibit E to the Partnership Agreement with respect to an Award LTIP Unit in an amount equal to the product of the LTIP Unit Initial Sharing Percentage for such Award LTIP Unit and the amount otherwise distributable or allocable with respect to such Award LTIP Unit.

(c)The LTIP Unit Initial Sharing Percentage shall be ten percent (10%). For the avoidance of doubt, after the applicable Hurdle Date, Award LTIP Units, both vested and (until and unless forfeited pursuant to Section 3(d), Section 4(c) or Section 5(a)(i)) unvested, shall be entitled to receive the same distributions payable with respect to Common Units if the payment date for such distributions is after the Distribution Participation Date, even though the record date for such distributions is before the Distribution Participation Date.

(d)The Distribution Participation Date with respect to any Distribution Equivalent LTIPs shall be the Grant Date of such Distribution Equivalent LTIPs.

(e)All distributions paid with respect to Award LTIP Units, both before and after the Distribution Participation Date, shall be fully vested and non-forfeitable when paid, whether or not the underlying LTIP Units have been earned based on performance or have become vested based on the passage of time as provided in Section 3 or Section 4 hereof.

7.Certain Adjustments. The LTIP Units shall be subject to adjustment as provided in the Partnership Agreement, and except as otherwise provided therein, if (i) the Company shall at any time be involved in a merger, consolidation, dissolution, liquidation, reorganization, exchange of shares, sale of all or substantially all of the assets or stock of the Company, spin-off of a Subsidiary, business unit or other transaction similar thereto, (ii) any stock dividend, stock split, reverse stock split, stock combination, reclassification, recapitalization, significant repurchases of stock, or other similar change in the capital structure of the Company, or any extraordinary dividend or other distribution to holders of the Shares or Common Units other than regular dividends shall occur, or (iii) any other

8

event shall occur that in each case in the good faith judgment of the Committee necessitates action by way of appropriate equitable adjustment in the terms of this Agreement, the Plan or the LTIP Units, then the Committee shall take such action as it deems necessary to maintain the Employee’s rights hereunder so that they are substantially proportionate to the rights existing under this Agreement and the terms of the LTIP Units prior to such event, including, without limitation: (A) adjustments in the LTIP Units; and (B) substitution of other awards under the Plan or otherwise. In the event of any change in the outstanding Shares (or corresponding change in the Conversion Factor applicable to Common Units) by reason of any share dividend or split, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other corporate change, or any distribution to common shareholders of the Company other than regular dividends, any Common Units, shares or other securities received by the Employee with respect to the applicable Award LTIP Unit which have not been earned or still subject to a risk of forfeiture will be subject to the same restrictions as the Award LTIP Units with respect to an equivalent number of shares or securities and shall be deposited with the Company.

8.Incorporation of Plan; Interpretation by Administrator. This Agreement is subject to the terms, conditions, limitations and definitions contained in the Plan, to the extent not inconsistent with the terms of this Agreement. In the event of any discrepancy or inconsistency between this Agreement and the Plan, the terms and conditions of this Agreement shall control. The Administrator may make such rules and regulations and establish such procedures for the administration of this Agreement, which are consistent with the terms of this Agreement, as it deems appropriate.

9.Certificates; Legend. Each certificate, if any, issued in respect of the Award LTIP Units awarded under this Agreement shall be registered in the Employee’s name and held by the Company until the expiration of the applicable Vesting Period. If certificates representing the LTIP Units are issued by the Partnership, at the expiration of each Vesting Period, the Company shall deliver to the Employee (or, if applicable, to the Employee’s legal representatives, beneficiaries or heirs) certificates representing the number of LTIP Units that vested upon the expiration of such Vesting Period. The records of the Partnership and any other documentation evidencing the Award LTIP Units shall bear an appropriate legend, as determined by the Partnership in its sole discretion, to the effect that such LTIP Units are subject to restrictions as set forth herein, in the Plan and in the Partnership Agreement.

10.Tax Withholding. The Company or its applicable affiliate (including the Partnership) has the right to withhold from cash compensation payable to the Employee all applicable income and employment taxes due and owing at the time the applicable portion of the Award LTIP Units becomes includible in the Employee’s income (the “Withholding Amount”), and/or to delay delivery of Award LTIP Units until appropriate arrangements have been made for payment of such withholding. In the alternative, the Company has the right to retain and cancel, or sell or otherwise dispose of, such number of Award LTIP Units as have a market value (determined as of the date the applicable LTIP Units vest) approximately equal to the Withholding Amount, with any excess proceeds being paid to Employee.

11.Amendment; Modification. This Agreement may only be modified or amended in a writing signed by the parties hereto, provided that the Employee acknowledges that the Plan may be amended or discontinued in accordance with the provisions thereof and that this Agreement may be amended or canceled by the Administrator, on behalf of the

9

Company and the Partnership, in each case for the purpose of satisfying changes in law or for any other lawful purpose, so long as no such action shall adversely affect the Employee’s rights under this Agreement without the Employee’s written consent. No promises, assurances, commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and whether express or implied, with respect to the subject matter hereof, have been made by the parties which are not set forth expressly in this Agreement. The failure of the Employee or the Company or the Partnership to insist upon strict compliance with any provision of this Agreement, or to assert any right the Employee or the Company or the Partnership, respectively, may have under this Agreement, shall not be deemed to be a waiver of such provision or right or any other provision or right of this Agreement.

12.Complete Agreement. Other than as specifically stated herein or as otherwise set forth in any employment, change in control or other agreement or arrangement to which the Employee is a party which specifically refers to the Award LTIP Units or to the treatment of compensatory equity held by the Employee generally, this Agreement (together with those agreements and documents expressly referred to herein, for the purposes referred to herein) embody the complete and entire agreement and understanding between the parties with respect to the subject matter hereof, and supersede any and all prior promises, assurances, commitments, agreements, undertakings or representations, whether oral, written, electronic or otherwise, and whether express or implied, which may relate to the subject matter hereof in any way.

13.Investment Representation; Registration. The Employee agrees that any resale of the LTIP Units received upon the expiration of the applicable Vesting Period (or the Shares) received upon redemption of or in exchange for LTIP Units or Common Units into which LTIP Units may have been converted) shall not occur during the “blackout periods” forbidding sales of Company securities, as set forth in the then-applicable Company employee manual or insider trading policy. In addition, any resale shall be made in compliance with the registration requirements of the Securities Act, or an applicable exemption therefrom, including, without limitation, the exemption provided by Rule 144 promulgated thereunder (or any successor rule). The Employee hereby makes the covenants, representations and warranties set forth on Exhibit B attached hereto as of the Grant Date. All of such covenants, warranties and representations shall survive the execution and delivery of this Agreement by the Employee. The Employee shall promptly notify the Partnership upon discovering that any of the representations or warranties set forth on Exhibit B was false when made or have, as a result of changes in circumstances, become false. The Partnership will have no obligation to register under the Securities Act any of the Award LTIP Units or any other securities issued pursuant to this Agreement or upon conversion or exchange of the Award LTIP Units into other limited partnership interests of the Partnership.

14.No Right to Employment. Nothing herein contained shall affect the right of the Company or any affiliate to terminate the Employee’s services, responsibilities and duties at any time for any reason whatsoever.

15.No Limit on Other Compensation Arrangements. Nothing contained in this Agreement shall preclude the Company from adopting or continuing in effect other or additional compensation plans, agreements or arrangements, and any such plans, agreements and arrangements may be either generally applicable or applicable only in specific cases or to specific persons.

10

16.Status of Award LTIP Units under the Plan. The Award LTIP Units are both issued as equity securities of the Partnership and granted as “Awards” under the Plan. The Company will have the right at its option, as set forth in the Partnership Agreement, to issue Shares in exchange for partnership units into which Award LTIP Units may have been converted pursuant to the Partnership Agreement, subject to certain limitations set forth in the Partnership Agreement, and such Shares, if issued, will be issued under the Plan. The Employee must be eligible to receive the LTIP Units in compliance with applicable federal and state securities laws and to that effect is required to complete, execute and deliver certain covenants, representations and warranties (attached as Exhibit B). The Employee acknowledges that the Employee will have no right to approve or disapprove such determination by the Company.

17.Severability. If, for any reason, any provision of this Agreement is held invalid, such invalidity shall not affect any other provision of this Agreement not so held invalid, and each such other provision shall to the full extent consistent with law continue in full force and effect. If any provision of this Agreement shall be held invalid in part, such invalidity shall in no way affect the rest of such provision not held so invalid, and the rest of such provision, together with all other provisions of this Agreement, shall to the full extent consistent with law continue in full force and effect.

18.Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to principles of conflict of laws.

22.Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and any successors to the Company and any successors to the Employee by will or the laws of descent and distribution, but this Agreement shall not otherwise be assignable or otherwise subject to hypothecation by the Employee.

23.Transfer; Redemption. None of the LTIP Units shall be sold, assigned, transferred, pledged or otherwise disposed of or encumbered (whether voluntarily or involuntarily or by judgment, levy, attachment, garnishment or other legal or equitable proceeding) (each such action, a “Transfer”), or redeemed in accordance with the Partnership Agreement (a) prior to vesting and (b) unless such Transfer is in compliance with all applicable securities laws (including, without limitation, the Securities Act), and such Transfer is in accordance with the applicable terms and conditions of the Partnership Agreement. Any attempted Transfer of LTIP Units not in accordance with the terms and

11

conditions of this Section 23 shall be null and void, and the Partnership shall not reflect on its records any change in record ownership of any LTIP Units as a result of any such Transfer, and shall otherwise refuse to recognize any such Transfer.

(vii)The Plan.

The Employee also acknowledges that any delivery of the Background Documents and other information relating to the Company and the Partnership prior to the determination by the Partnership of the suitability of the Employee as a holder of Award LTIP Units shall not constitute an offer of Award LTIP Units until such determination of suitability shall be made.

(b)The Employee hereby represents and warrants that:

(i)The Employee either (A) is an “accredited investor” as defined in Rule 501(a) under the Securities Act of 1933, as amended (the “Securities Act”), or (B) by reason of the business and financial experience of the Employee, together with the business and financial experience of those persons, if any, retained by the Employee to represent or advise him with respect to the grant to him of LTIP Units, the potential conversion of LTIP Units into Common Partnership Units of the Partnership (“Common Units”) and the potential redemption of such Common Units for the Company’s common Shares (“REIT Shares”), has such knowledge, sophistication and experience in financial and business matters and in making investment decisions of this type that the Employee (I) is capable of evaluating the merits and risks of an investment in the Partnership and potential investment in the Company and of making an informed investment decision, (II) is capable of protecting his own interest or has engaged representatives or advisors to assist him in protecting his interests, and (III) is capable of bearing the economic risk of such investment.

17

(ii)The Employee understands that (A) the Employee is responsible for consulting his own tax advisors with respect to the application of the U.S. federal income tax laws, and the tax laws of any state, local or other taxing jurisdiction to which the Employee is or by reason of the award of LTIP Units may become subject, to his particular situation; (B) the Employee has not received or relied upon business or tax advice from the Company, the Partnership or any of their respective employees, agents, consultants or advisors, in their capacity as such; (C) the Employee provides services to the Partnership on a regular basis and in such capacity has access to such information, and has such experience of and involvement in the business and operations of the Partnership, as the Employee believes to be necessary and appropriate to make an informed decision to accept this award of LTIP Units; and (D) an investment in the Partnership and/or the Company involves substantial risks. The Employee has been given the opportunity to make a thorough investigation of matters relevant to the LTIP Units and has been furnished with, and has reviewed and understands, materials relating to the Partnership and the Company and their respective activities (including, but not limited to, the Background Documents). The Employee has been afforded the opportunity to obtain any additional information (including any exhibits to the Background Documents) deemed necessary by the Employee to verify the accuracy of information conveyed to the Employee. The Employee confirms that all documents, records, and books pertaining to his receipt of LTIP Units which were requested by the Employee have been made available or delivered to the Employee. The Employee has had an opportunity to ask questions of and receive answers from the Partnership and the Company, or from a person or persons acting on their behalf, concerning the terms and conditions of the LTIP Units. The Employee has relied upon, and is making its decision solely upon, the Background Documents and other written information provided to the Employee by the Partnership or the Company.

(iii)The LTIP Units to be issued, the Common Units issuable upon conversion of the LTIP Units and any REIT Shares issued in connection with the redemption of any such Common Units will be acquired for the account of the Employee for investment only and not with a current view to, or with any intention of, a distribution or resale thereof, in whole or in part, or the grant of any participation therein, without prejudice, however, to the Employee’s right (subject to the terms of the LTIP Units, the Plan and this Agreement) at all times to sell or otherwise dispose of all or any part of his LTIP Units, Common Units or REIT Shares in compliance with the Securities Act, and applicable state securities laws, and subject, nevertheless, to the disposition of his assets being at all times within his control.

(iv)The Employee acknowledges that (A) neither the LTIP Units to be issued, nor the Common Units issuable upon conversion of the LTIP Units, have been registered under the Securities Act or state securities laws by reason of a specific exemption or exemptions from registration under the Securities Act and applicable state securities laws and, if such LTIP Units or Common Units are represented by certificates, such certificates will bear a legend to such effect, (B) the reliance by the Partnership and the Company on such exemptions is predicated in part on the accuracy and completeness of the representations and warranties of the Employee contained herein, (C) such LTIP Units or Common Units, therefore, cannot be resold unless registered under the Securities Act and applicable state securities laws, or unless an exemption from registration is available, (D) there is no public market for such LTIP Units and Common Units and (E) neither the Partnership nor the Company has any obligation or intention to register such LTIP Units or the Common Units issuable upon conversion of the LTIP Units under the Securities Act or any state securities laws or to take any action that would make available any exemption from the registration requirements of such laws, except that, upon the redemption of the Common Units for

18

REIT Shares, the Company may issue such REIT Shares under the Plan and pursuant to a Registration Statement on Form S-8 under the Securities Act, to the extent that (I) the Employee is eligible to receive such REIT Shares under the Plan at the time of such issuance, (II) the Company has filed a Form S-8 Registration Statement with the Securities and Exchange Commission registering the issuance of such REIT Shares and (III) such Form S-8 is effective at the time of the issuance of such REIT Shares.

1.Organization and Basis of Presentation

Organization

JBG SMITH Properties ("JBG SMITH"), a Maryland real estate investment trust ("REIT"), owns and operates a portfolio of commercial and multifamily assets amenitized with ancillary retail. JBG SMITH's portfolio reflects its longstanding strategy of owning and operating assets within Metro-served submarkets in the Washington, D.C. metropolitan area that have high barriers to entry and vibrant urban amenities. Over half of our portfolio is in National Landing in Northern Virginia, where we serve as the exclusive developer for Amazon.com, Inc.'s ("Amazon") new headquarters and where Virginia Tech's under-construction $1 billion Innovation Campus is located. In addition, our third-party asset management and real estate services business provides fee-based real estate services to the Washington Housing Initiative ("WHI") Impact Pool, Amazon, 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, 2021, JBG SMITH, as its sole general partner, controlled JBG SMITH LP and owned 90.8% of its common limited partnership units ("OP Units"). JBG SMITH is hereinafter referred to 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.

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, 2021, our Operating Portfolio consisted of 63 operating assets comprising 42 commercial assets totaling 13.1 million square feet (11.3 million square feet at our share) and 21 multifamily assets totaling 7,776 units (6,125 units at our share). Additionally, we have: (i) one under-construction multifamily asset with 808 units (808 units at our share); (ii) 11 near-term development assets totaling 5.3 million square feet (5.0 million square feet at our share) of estimated potential development density; and (iii) 25 future development assets totaling 14.3 million square feet (11.6 million square feet at our share) of estimated potential development density.

We derive our revenue primarily from leases with commercial and multifamily tenants, which 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, 2021 and 2020 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, 2020, filed with the Securities and Exchange Commission.

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 on our VIEs. 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 condensed consolidated financial statements as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. References to our balance sheets refer to our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. References to our statements of operations refer to our condensed consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020. References to our statements of comprehensive income (loss) refer to our condensed consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2021 and 2020.

Income Taxes

We have elected to be taxed as a 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 these activities.

2.Summary of Significant Accounting Policies

Significant Accounting Policies

There were no material changes to our significant accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020.

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 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. The most significant of these estimates include: (i) the underlying cash flows and holding periods used in assessing impairment of long-lived assets; (ii) the determination of useful lives for tangible and intangible assets; and (iii) the assessment of the collectability of receivables, including deferred rent receivables. Longer estimated holding periods for real estate assets directly reduce the likelihood of recording an impairment loss. If there is a change in the strategy for an asset or if market conditions dictate an earlier sale date, an impairment loss may be recognized, and such loss could be material.

In March 2020, the World Health Organization declared a global pandemic related to the novel coronavirus ("COVID-19"). The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the distribution, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. The ultimate adverse impact of COVID-19 is highly uncertain; however, the effects of COVID-19 on us and our tenants have affected estimates used in the preparation of the underlying cash flows used in assessing our long-lived assets for impairment and the assessment of the collectability of receivables from tenants, including deferred rent receivables. We have made what we believe to be appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent these estimates differ from actual results, our consolidated financial statements may be materially affected.

Due to the business disruptions and challenges caused by COVID-19, we have provided rent deferrals and other lease concessions to certain tenants. We have entered into agreements with certain tenants, many of which have been placed on the cash basis of accounting, resulting in the deferral to future periods or abatement of $492,000 of rent that had been contractually due in the third quarter of 2021. We are negotiating additional rent deferrals and other lease concessions with

some of our tenants, which have been considered when establishing credit losses against billed and deferred rent receivables. During 2020, we began recognizing revenue from substantially all co-working tenants and retailers except for grocers, pharmacies, essential businesses and certain national credit tenants on the cash basis of accounting.

Recent Accounting Pronouncements

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04, Reference Rate Reform ("Topic 848"). Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in Topic 848 is optional and may be elected over the period of March 12, 2020 through December 31, 2022 as reference rate reform activities occur. During the nine months ended September 30, 2021, we did not make any elections. During the year ended December 31, 2020, we elected to apply the hedge accounting expedients related to (i) the assertion that our hedged forecasted transactions remain probable and (ii) the assessments of effectiveness for future London Interbank Offered Rate ("LIBOR") indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves our past presentation of our derivatives. We will continue to evaluate the impact of the guidance and may apply other elections, as applicable.

Acquisition

We have agreed, subject to customary closing conditions, to acquire The Batley, a 432-unit multifamily asset in the Union Market submarket of Washington, D.C., for a purchase price of approximately $205 million. The building was 90.7% occupied as of September 30, 2021. We expect the acquisition to close in 2021. We intend to use The Batley as a replacement property in a like-kind exchange for the proceeds from the sale of Pen Place to Amazon, which is expected to close during the second quarter of 2022.

Dispositions

In April 2021, we invested cash in and contributed land to two real estate ventures and recognized an $11.3 million gain, which is included in "Gain on sale of real estate" in our statements of operations for the nine months ended September 30, 2021. See Note 4 for additional information.

During the three and nine months ended September 30, 2021, we recognized our proportionate share of the gain from the sale of various assets by our unconsolidated real estate ventures, which is included in "Income (loss) from unconsolidated real estate ventures, net" in our statements of operations. See Note 4 for additional information.

(1) Reflects our effective ownership interests in the underlying real estate as of September 30, 2021. We have multiple investments with certain venture partners with varying ownership interests in the underlying real estate.

(2) J.P. Morgan is the advisor for an institutional investor.

(3) As of September 30, 2021 and December 31, 2020, our total investments in unconsolidated real estate ventures were greater than the net book value of the underlying assets by $20.2 million and $18.9 million, resulting principally from capitalized interest and our zero investment balance in the real estate venture with CPPIB that owns 1101 17th Street.

In April 2021, we entered into two real estate ventures with an institutional investor advised by J.P. Morgan, in which we have 50% ownership interests, to design, develop, manage and own approximately 2.0 million square feet of new mixed-use development located in Potomac Yard, the southern portion of National Landing. Our venture partner contributed a land site that is entitled for 1.3 million square feet of development at Potomac Yard Landbay F, while we contributed cash and adjacent land with over 700,000 square feet of estimated development capacity at Potomac Yard Landbay G. We will also act as pre-developer, developer, property manager and leasing agent for all future commercial and residential properties on the site. We have determined the ventures are VIEs, but we are not the primary beneficiary of the VIEs and, accordingly, we have not consolidated either venture. We recognized an $11.3 million gain on the land contributed to one of the real estate ventures based on the cash received and the remeasurement of our retained interest in the asset, which was included in "Gain on sale of real estate" in our statements of operations for the nine months ended September 30, 2021. As part of the transaction, our venture partner elected to accelerate the monetization of a 2013 promote interest in the land contributed by it to the ventures. During the second quarter of 2021, the total amount of the promote paid was $17.5 million, of which $4.2 million was paid to certain of our non-employee trustees and certain of our executives.

A reconsideration event could cause us to consolidate an unconsolidated real estate venture in the future or deconsolidate a consolidated entity. We evaluate reconsideration events as we become aware of them. Reconsideration events include amendments to real estate venture agreements and changes in our partner's ability to make contributions to the venture. Under certain circumstances, we may purchase our partner's interest.

Variable Interest Entities

Variable Interest Entities

Variable Interest Entities

5.Variable Interest Entities

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, 2021 and December 31, 2020, we had interests in entities deemed to be VIEs. Although we are engaged to act as the managing partner in charge of 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, 2021 and December 31, 2020, the net carrying amount of our investment in these entities was $165.4 million and $116.2 million, which is included in "Investments in unconsolidated real estate ventures" in our balance sheets. Our equity in the income of unconsolidated VIEs is 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 90.8% 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 and hold our assets and liabilities through JBG SMITH LP, its total assets and liabilities comprise substantially all of our consolidated assets and liabilities.

Through the structure of the 1900 Crystal Drive transaction we executed in March 2021, we have the ability to facilitate an exchange out of an asset into 1900 Crystal Drive. We leased the land underlying 1900 Crystal Drive located in National

Landing to a lessee, which plans to construct an 808-unit multifamily asset comprising two towers with ground floor retail. The ground lessee has engaged us to be the development manager for the construction of 1900 Crystal Drive, and separately, we are the lessee in a master lease of the asset. We have an option to acquire the asset until a specified period after completion. In March 2021, the ground lessee entered into a mortgage loan collateralized by the leasehold interest with a maximum principal balance of $227.0 million and an interest rate of LIBOR plus 3.0% per annum. As of September 30, 2021, no proceeds had been received from the mortgage loan. In connection with the mortgage loan, we have guaranteed the completion of the asset and provided certain carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy). The ground lessee was obligated to invest $17.5 million of equity funding, all of which has been funded, and we are obligated to provide additional project funding through a mezzanine loan to the ground lessee, of which we have funded $11.7 million as of September 30, 2021. We determined that 1900 Crystal Drive is a VIE and that we are the primary beneficiary of the VIE. Accordingly, we consolidate the VIE with the lessee's ownership interest shown as "Noncontrolling interests" in our balance sheet. The ground lease, the mezzanine loan and the master lease described above are eliminated in consolidation. As of September 30, 2021, the VIE had total assets and liabilities of $29.7 million and $4.5 million. The assets of the VIE can only be used to settle the obligations of the VIE, and the liabilities include third-party liabilities of the VIE for which the creditors or beneficial interest holders do not have recourse against us.

Accordingly, we have concluded that the licenses are indefinite-lived intangible assets.

JBG SMITH LP

OP Units held by persons other than JBG SMITH are redeemable for cash or, at our election, our common shares, subject to certain limitations. During the nine months ended September 30, 2021 and 2020, unitholders redeemed 829,107 and 1.1 million OP Units, which we elected to redeem for an equivalent number of our common shares. As of September 30, 2021, outstanding OP Units totaled 13.1 million, representing a 9.2% ownership interest in JBG SMITH LP. On our balance sheets, our OP Units and certain vested long-term incentive partnership units ("LTIP Units") are presented at the higher of their redemption value or their carrying value, with adjustments to the redemption value recognized in "Additional paid-in capital." Redemption value per OP Unit is equivalent to the market value of one of our common shares at the end of the period. In October 2021, unitholders redeemed 20,953 OP Units, which we elected to redeem for an equivalent number of our common shares.

Consolidated Real Estate Venture

We are a partner in a consolidated real estate venture that owns a multifamily asset located in Washington, D.C. Pursuant to the terms of the real estate venture agreement, we are obligated to fund all capital contributions until our ownership interest reaches a maximum of 97.0%. Our partner can redeem its interest for cash under certain conditions. As of September 30, 2021, we held a 96.0% ownership interest in the real estate venture.

LTIP Units and Time-Based LTIP Units

During the nine months ended September 30, 2021, we granted to certain employees 498,955 LTIP Units with time-based vesting requirements ("Time-Based LTIP Units") with a weighted average grant-date fair value of $29.21 per unit that

primarily vest ratably over four years subject to continued employment. Compensation expense for these units is being recognized over a four-year period.

Additionally, in January 2021, we granted 163,065 fully vested LTIP Units to certain employees, who elected to receive all or a portion of their cash bonus, related to 2020 service, as LTIP Units. The LTIP units had a grant-date fair value of $29.54 per unit. Compensation expense totaling $4.8 million for these LTIP Units was recognized in 2020.

In April 2021, as part of their annual compensation, we granted to non-employee trustees a total of 71,792 fully vested LTIP Units with an aggregate grant-date fair value of $1.9 million. The LTIP Units may not be sold while a trustee is serving on the Board of Trustees.

In July 2021, we granted to certain employees 608,325 Time-Based LTIP Units with a weighted average grant-date fair value of $31.73 per unit that vest 50% on the fifth anniversary of the grant date and 25% on each of the sixth and seventh anniversaries of the grant date, subject to continued employment. Compensation expense for these units is being recognized over a seven-year period.

The aggregate grant-date fair value of the Time-Based LTIP Units and LTIP Units granted during the nine months ended September 30, 2021 was $40.6 million. The Time-Based LTIP Units and LTIP Units were valued based on the closing common share price on the date of grant, less a discount for post-grant restrictions. The discount was determined using Monte Carlo simulations, and the following is a summary of the significant assumptions used to value these units:

Expected volatility	34.0% to 39.0%
Risk-free interest rate	0.1% to 0.4%
Post-grant restriction periods	2 to 3 years

Performance-Based LTIP Units

In January 2021, we granted to certain employees 627,874 LTIP Units with performance-based vesting requirements ("Performance-Based LTIP Units") with a weighted average grant-date fair value of $15.14 per unit. Our Performance-Based LTIP Units have a three-year performance period. 50% of any Performance-Based LTIP Units that are earned vest at the end of the three-year performance period and the remaining 50% vest on the fourth anniversary of the date of grant, subject to continued employment. If, however, the Performance-Based LTIP Units do not achieve a positive absolute total shareholder return ("TSR") at the end of the three-year performance period, but satisfy the relative performance criteria thereof, 50% of the units that otherwise could have been earned will be forfeited, and the remaining units that are earned will vest if and when we achieve a positive TSR during the succeeding seven years, measured at the end of each quarter. Compensation expense for these units is generally being recognized over a four-year period. In January 2021, the three-year performance period ended for the Performance-Based LTIP Units granted on February 2, 2018. Based on our relative performance and absolute TSR over the three-year performance period, 100% of the units granted were earned.

In July 2021, we granted to certain employees 844,070 Performance-Based LTIP Units with a weighted average grant-date fair value of $23.08 per unit that vest 50% on the fifth anniversary of the grant date and 25% on each of the sixth and seventh anniversaries of the grant date, subject to continued employment, and earn based on our achievement of four share price targets during the performance period commencing on the first anniversary of the grant date and ending on the sixth anniversary of the grant date. Compensation expense for these units is being recognized over a seven-year period.

The aggregate grant-date fair value of the Performance-Based LTIP Units granted during the nine months ended September 30, 2021 was $29.0 million, valued using Monte Carlo simulations. The following is a summary of the significant assumptions used to value the Performance-Based LTIP Units:

Expected volatility	31.0% - 34.0%
Dividend yield	2.6%
Risk-free interest rate	0.2% - 1.0%

Restricted Share Units ("RSUs")

In January 2021, we granted to certain non-executive employees 22,194 RSUs with time-based vesting requirements ("Time-Based RSUs") with a weighted average grant-date fair value of $31.52 per unit and 13,516 RSUs with performance-based vesting requirements ("Performance-Based RSUs") with a weighted average grant-date fair value of $15.16 per unit. Vesting requirements and compensation expense recognition for the Time-Based RSUs and the Performance-Based RSUs are identical to those of the Time-Based LTIP Units and Performance-Based LTIP Units granted in January 2021.

The aggregate grant-date fair value of the RSUs granted during the nine months ended September 30, 2021 was $905,000. The Time-Based RSUs were valued based on the closing common share price on the date of grant and the Performance-Based RSUs were valued using Monte Carlo simulations with the same significant assumptions used to value the Performance-Based LTIP Units above.

ESPP

Pursuant to the ESPP, employees purchased 34,320 common shares for $880,000 during the nine months ended September 30, 2021. The following is a summary of the significant assumptions used to value the ESPP common shares using the Black-Scholes model:

The following is a summary of the calculation of basic and diluted earnings (loss) per common share and a reconciliation of the amounts of net income (loss) available to common shareholders used in calculating basic and diluted earnings per common share to net income (loss):

Earnings (loss) per common share - basic and diluted	$	0.00	$	(0.18)		$	(0.18)	$	(0.14)

The effect of the redemption of OP Units, LTIP Units and Time-Based LTIP Units that were outstanding as of September 30, 2021 and 2020 is excluded in the computation of diluted earnings 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 earnings per share). Since OP Units, LTIP Units and Time-Based LTIP Units, 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 OP Units, LTIP Units and Time-Based LTIP Unit impact are excluded from net income (loss) available to common shareholders and from the weighted average number of common shares outstanding in calculating diluted earnings per common share. Performance-Based LTIP Units, Special Performance-Based LTIP Units, Formation Awards and RSUs, which totaled 5.2 million and 4.9 million for the three and nine months ended September 30, 2021, and 4.4 million and 4.9 million for the three and nine months ended September 30, 2020, were excluded from the calculation of diluted earnings per common share as they were antidilutive, but potentially could be dilutive in the future.

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. We do not enter into derivative financial instruments for speculative purposes.

As of September 30, 2021 and December 31, 2020, 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 loss on our derivative financial instruments designated as cash flow hedges was $27.8 million and $43.9 million as of September 30, 2021 and December 31, 2020 and was recorded in "Accumulated other comprehensive loss" in our balance sheets, of which a portion was reclassified to "Redeemable noncontrolling interests." Within the next 12 months, we expect to reclassify $14.6 million of net unrealized loss as an increase 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:

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 under authoritative accounting guidance, 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, 2021 and December 31, 2020, 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 and losses included in "Other comprehensive income (loss)" in our statements of comprehensive income (loss) for the three and nine months ended September 30, 2021 and 2020 were attributable to the net change in unrealized gains or losses related to the interest rate swaps that were outstanding during those periods, none of which were reported in our statements of operations as the interest rate swaps were documented and qualified as hedging instruments.

Financial Assets and Liabilities Not Measured at Fair Value

As of September 30, 2021 and December 31, 2020, 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, 2021				December 31, 2020
	Carrying				Carrying
	Amount (1)		Fair Value		Amount (1)		Fair Value
	(In thousands)
Financial liabilities:
Mortgages payable	$	1,684,407	$	1,739,548	$	1,603,869	$	1,606,470
Unsecured term loans		400,000		400,201		400,000		399,678

(1) The carrying amount consists of principal only.

The fair values of the mortgages payable and unsecured term loans were determined using Level 2 inputs of the fair value hierarchy. The fair value of our mortgages payable 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 unsecured 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.Segment Information

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 Chief Operating Decision Maker ("CODM"), makes key operating decisions, evaluates financial results, allocates resources and manages our business. Accordingly, we aggregate our operating segments into three reportable segments (commercial, multifamily, 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. The following represents the components of revenue from our third-party real estate services business:

(2) Represents reimbursement of expenses incurred by us on behalf of third parties, including allocated payroll costs and amounts paid to third-party contractors for construction management projects.

Management company assets primarily consist of management and leasing contracts with a net book value of $21.1 million and $25.5 million as of September 30, 2021 and December 31, 2020, which are classified in "Other assets, net" in our balance sheets.

Commitments and Contingencies

Commitments and Contingencies

Commitments and Contingencies

17.Commitments and Contingencies

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 $1.5 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 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 mortgages payable secured by our properties, a revolving credit facility and unsecured 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 reasonable costs 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, 2021, we had assets under construction that will, based on our current plans and estimates, require an additional $320.3 million to complete, which we anticipate will be primarily expended over the next three years. These capital expenditures are generally due as the work is performed, and we expect to finance them with debt proceeds, proceeds from asset recapitalizations and sales, issuance and sale of securities, and available cash.

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 assets. The environmental assessments did not reveal 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 $18.2 million as of September 30, 2021 and December 31, 2020 and are included in "Other liabilities, net" in our balance sheets.

Other

As of September 30, 2021, we had committed tenant-related obligations totaling $76.9 million ($73.6 million related to our consolidated entities and $3.3 million 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.

There are various 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.

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, 2021, we had additional capital commitments and certain recorded guarantees to our unconsolidated real estate ventures totaling $66.1 million. As of September 30, 2021, we had no principal payment guarantees related to our unconsolidated real estate ventures.

Additionally, with respect to borrowings of our consolidated entities, we have agreed, and may in the future 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. As of September 30, 2021, the aggregate amount of principal payment guarantees was $8.3 million for our consolidated entities.

Our third-party asset management and real estate services business provides fee-based real estate services to the WHI, Amazon, the JBG Legacy Funds and other third parties. We provide services for the benefit of the JBG Legacy Funds that own interests in the assets retained by the JBG Legacy Funds. In connection with the contribution to us of the 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 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.

We launched the WHI with the Federal City Council in June 2018 as a scalable market-driven model that uses private capital to help address the scarcity of housing for middle income families. We are the manager for the WHI Impact Pool, which is the social impact debt financing vehicle of the WHI. As of September 30, 2021, the WHI Impact Pool had completed closings of capital commitments totaling $114.4 million, which included a commitment from us of $11.2 million. As of September 30, 2021, our remaining commitment was $8.3 million.

The third-party real estate services revenue, including expense reimbursements, from the JBG Legacy Funds and the WHI Impact Pool was $5.6 million and $17.2 million for the three and nine months ended September 30, 2021, and $4.6 million and $17.3 million for the three and nine months ended September 30, 2020. As of September 30, 2021 and December 31, 2020, we had receivables from the JBG Legacy Funds and the WHI Impact Pool totaling $3.5 million and $7.5 million for such services.

We rented our former corporate offices from an unconsolidated real estate venture and made payments totaling $246,000 and $1.0 million for the three and nine months ended September 30, 2021, and $403,000 and $4.1 million for the three and nine months ended September 30, 2020.

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 $4.9 million and $13.4 million during the three and nine months ended September 30, 2021, and $4.0 million and $12.6 million for the three and nine months ended September 30, 2020, which is 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, 2021 and 2020 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, 2020, filed with the Securities and Exchange Commission.

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 on our VIEs. 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 condensed consolidated financial statements as of September 30, 2021 and December 31, 2020, and for the three and nine months ended September 30, 2021 and 2020. References to our balance sheets refer to our condensed consolidated balance sheets as of September 30, 2021 and December 31, 2020. References to our statements of operations refer to our condensed consolidated statements of operations for the three and nine months ended September 30, 2021 and 2020. References to our statements of comprehensive income (loss) refer to our condensed consolidated statements of comprehensive income (loss) for the three and nine months ended September 30, 2021 and 2020.

Income Taxes

Income Taxes

We have elected to be taxed as a 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 these 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 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. The most significant of these estimates include: (i) the underlying cash flows and holding periods used in assessing impairment of long-lived assets; (ii) the determination of useful lives for tangible and intangible assets; and (iii) the assessment of the collectability of receivables, including deferred rent receivables. Longer estimated holding periods for real estate assets directly reduce the likelihood of recording an impairment loss. If there is a change in the strategy for an asset or if market conditions dictate an earlier sale date, an impairment loss may be recognized, and such loss could be material.

In March 2020, the World Health Organization declared a global pandemic related to the novel coronavirus ("COVID-19"). The significance, extent and duration of the impact of COVID-19 on us and our tenants remains largely uncertain and dependent on near-term and future developments that cannot be accurately predicted at this time, such as the continued severity, duration, transmission rate and geographic spread of COVID-19, the distribution, effectiveness and willingness of people to take COVID-19 vaccines, the extent and effectiveness of the containment measures taken, and the response of the overall economy, the financial markets and the population, particularly in the area in which we operate. The ultimate adverse impact of COVID-19 is highly uncertain; however, the effects of COVID-19 on us and our tenants have affected estimates used in the preparation of the underlying cash flows used in assessing our long-lived assets for impairment and the assessment of the collectability of receivables from tenants, including deferred rent receivables. We have made what we believe to be appropriate accounting estimates based on the facts and circumstances available as of the reporting date. To the extent these estimates differ from actual results, our consolidated financial statements may be materially affected.

Due to the business disruptions and challenges caused by COVID-19, we have provided rent deferrals and other lease concessions to certain tenants. We have entered into agreements with certain tenants, many of which have been placed on the cash basis of accounting, resulting in the deferral to future periods or abatement of $492,000 of rent that had been contractually due in the third quarter of 2021. We are negotiating additional rent deferrals and other lease concessions with

some of our tenants, which have been considered when establishing credit losses against billed and deferred rent receivables. During 2020, we began recognizing revenue from substantially all co-working tenants and retailers except for grocers, pharmacies, essential businesses and certain national credit tenants on the cash basis of accounting.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2020-04, Reference Rate Reform ("Topic 848"). Topic 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in Topic 848 is optional and may be elected over the period of March 12, 2020 through December 31, 2022 as reference rate reform activities occur. During the nine months ended September 30, 2021, we did not make any elections. During the year ended December 31, 2020, we elected to apply the hedge accounting expedients related to (i) the assertion that our hedged forecasted transactions remain probable and (ii) the assessments of effectiveness for future London Interbank Offered Rate ("LIBOR") indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves our past presentation of our derivatives. We will continue to evaluate the impact of the guidance and may apply other elections, as applicable.
