OUR COMPANY

        JBG SMITH is a real estate investment trust that owns, operates, invests in and develops real estate assets concentrated in leading urban infill submarkets in and around Washington, DC. We own and operate a portfolio of high-quality office and multifamily assets, many of which are amenitized with ancillary retail. In addition, our third-party asset management and real estate services platform provides fee-based real estate services to the legacy funds formerly organized by The JBG Companies and other third parties. References to "our share" refer to our ownership percentage of consolidated and unconsolidated assets in real estate ventures. JBG SMITH operates as a real estate investment trust ("REIT") for U.S. federal income tax purposes.

        As of March 31, 2018, our operating portfolio consists of 68 operating assets comprising 50 office assets totaling over 13.7 million square feet (11.8 million square feet at our share), 14 multifamily assets totaling 6,016 units (4,232 units at our share) and four other assets totaling approximately 765,000 square feet (348,000 square feet at our share). Additionally, we have (i) 10 assets under construction comprising four office assets totaling approximately 1.3 million square feet (1.1 million square feet at our share), five multifamily assets totaling 1,767 units (1,568 units at our share) and one other asset totaling approximately 41,100 square feet (4,100 square feet at our share); and (ii) 43 future development assets totaling approximately 21.3 million square feet (17.9 million square feet at our share) of estimated potential development density.

        JBG SMITH was organized by Vornado Realty Trust ("Vornado") as a Maryland real estate investment trust on October 27, 2016 (capitalized on November 22, 2016). JBG SMITH was formed for the purpose of receiving, via the spin-off on July 17, 2017 (the "separation"), substantially all of the assets and liabilities of Vornado's Washington, DC segment, which operated as Vornado / Charles E. Smith, (the "Vornado Included Assets"). On July 18, 2017, JBG SMITH acquired the management business and certain assets and liabilities of The JBG Companies (the "combination"). The separation and the combination are collectively referred to as the "formation transaction." Unless the context otherwise requires, all references to "we," "us," and "our," refer to the Vornado Included Assets (our predecessor and accounting acquirer) for periods prior to the separation and to JBG SMITH for periods after the separation. Substantially all of our assets are held by, and our operations are conducted through, JBG SMITH Properties LP (the "Operating Partnership"), our operating partnership. We act as general partner of the Operating Partnership and exercise full responsibility, discretion and control over its day-to-day management.

Corporate Information

        We are a Maryland real estate investment trust. The address of our principal executive office is 4445 Willard Avenue, Suite 400, Chevy Chase, Maryland 20815. The telephone number for our principal executive office is (240) 333-3600.

INFORMATION ABOUT THE PROGRAM

        The following questions and answers explain and constitute the governing document for JBG SMITH Direct.

Purpose

1.     What is JBG SMITH Direct?

        JBG SMITH Direct is a convenient direct share purchase and dividend reinvestment program available for new investors to make an initial investment in JBG SMITH shares, and for existing shareholders to increase their holdings of JBG SMITH shares. Participants in the program may elect to have dividends automatically reinvested in JBG SMITH shares and/or to make optional cash investments through the program administrator, AST.

        Participation in JBG SMITH Direct is entirely voluntary, and we give no advice regarding your decision to join the program. However, if you decide to participate in this program, an enrollment form and reply envelope are enclosed for your convenience. Enrollment forms are also available by contacting AST at the address listed in Question 26.

        Please retain all account statements for your records. The statements contain important tax and other information.

Eligibility and Enrollment

3.     Who is eligible to participate in JBG SMITH Direct?

        New Investors: If you do not currently own any JBG SMITH shares, you can participate in JBG SMITH Direct by making an initial purchase of common shares through JBG SMITH Direct with a minimum investment of $250.

S-6


Table of Contents

        Record Owners: You are a record owner if you own common shares that are registered in your name with JBG SMITH's transfer agent, AST. If you are a record owner, you may participate directly in any or all of the features of JBG SMITH Direct.

        Beneficial Owners: You are a beneficial owner if you own common shares that are registered in the name of a financial intermediary (i.e., broker, bank or other nominee). If you are a beneficial owner, you must either (i) become a record owner by having one or more shares transferred into your own name, (ii) enroll in the program in the same manner as someone who is not currently a JBG SMITH shareholder with a minimum investment of $250 or (iii) coordinate your dividend reinvestment through the broker, bank or other nominee in whose name your common shares are held.

        All U.S. citizens are eligible to participate in JBG SMITH Direct, whether or not they are currently JBG SMITH shareholders.

        If you are not a U.S. citizen, you can participate in JBG SMITH Direct provided there are no laws or governmental regulations that would prohibit you from participating or laws or governmental regulations that would affect the terms of JBG SMITH Direct. JBG SMITH reserves the right to terminate participation of any shareholder if it deems it advisable under any foreign laws or regulations. All program funds must be in U.S. funds and drawn on a U.S. bank. If you are not in the U.S., contact your bank to verify that they can provide you with a check that clears through a U.S. bank and can print the dollar amount in U.S. funds. Due to the longer clearance period, we are unable to accept checks clearing through non-U.S. banks. Please contact your local bank for details on how to make the transaction.

4.     Are there fees associated with participation?

        There is no cost to you for reinvesting your dividends. JBG SMITH will pay all fees for dividend reinvestments and the annual maintenance cost for your account.

        There is no fee for purchasing shares with optional cash investments by check or with automatic investments and there is no enrollment fee for joining JBG SMITH Direct. However, each participant will pay a pro rata per share broker's commissions incurred in connection with open-market purchases (currently, $0.05 per share which will be deducted from your optional cash investment funds).

        If you instruct AST to sell any of your JBG SMITH shares, you will be charged a service fee of $15.00 plus a $0.12 per share broker's commission, which will be deducted from the proceeds derived from the sale. See Question 22 for more information.

5.     How does a JBG SMITH shareholder enroll in the program?

        If you are already a JBG SMITH shareholder of record (that is, if you own JBG SMITH shares that are registered in your name, not your broker's) but you are not enrolled in JBG SMITH Direct, you may enroll in the program simply by completing and returning the enclosed shareholder enrollment form to AST or by enrolling online through AST's website, www.astfinancial.com/issuer-investor-services. You may obtain additional shareholder enrollment forms at any time upon request to AST.

6.     I already own JBG SMITH shares, but they are held by my bank or broker and registered in "street name." Can I use those shares to participate in the program?

        Yes. To become a participant, you may choose from among the following options:

Dividend Reinvestment Options

        As a participant in the program, you may elect to reinvest all, part or none of the dividends on your JBG SMITH shares for the purchase of additional JBG SMITH shares. The options available to you are as follows:

        The dates on which dividends will be reinvested are described in Question 14. AST will continue to reinvest your dividends as you have indicated on your enrollment form until you specify otherwise.

S-8


Table of Contents

You may change your election at any time by either completing and submitting a new enrollment form, by contacting AST directly at 1-866-673-8056 or by accessing your program account through the Internet at AST's website, www.astfinancial.com/issuer-investor-services. No matter which reinvestment option you have selected, you may make optional cash investments as described in Question 11.

9.     How may I change my dividend reinvestment option or discontinue reinvesting my dividends?

        You may change dividend reinvestment options by instructing AST in writing at its address listed in Question 26, by submitting to AST a new election on an enrollment form, or by accessing your program account through the Internet at AST's website, www.astfinancial.com/issuer-investor-services. To be effective for a specific dividend, any change must be received by AST before the record date for that dividend. See Question 14 for information regarding record dates.

        You may discontinue reinvestment of cash dividends at any time by calling or writing to AST or by accessing your program account through the Internet at AST's website at www.astfinancial.com/issuer-investor-services. If AST receives your request to discontinue dividend reinvestment shortly before, on, or shortly after a record date for a dividend, AST may either pay the dividend in cash or reinvest it under the program on the next investment date on your behalf. If reinvested, AST may sell the JBG SMITH shares purchased and send the proceeds to you, less any service fee, applicable processing fee and any other costs of sale. After processing your request to discontinue dividend reinvestment, any JBG SMITH shares credited to your account under JBG SMITH Direct will continue to be held in book-entry form. Dividends on any JBG SMITH shares held in book-entry form, and on any JBG SMITH shares you hold in certificate form, will be paid in cash by check or direct deposit (at your option). To receive cash dividends by direct deposit, see Question 10.

10.   May I receive dividend payments by direct deposit?

        Yes. Through the program's direct deposit feature, instead of receiving dividend checks, you may elect to have your cash dividends paid by electronic funds transfer to your account at a U.S. bank or financial institution on the dividend payment date. To receive dividends by direct deposit, you must complete, sign and return to AST an authorization for electronic direct deposit form. You may obtain this form by calling AST directly at 1-866-673-8056. You may also elect direct deposit online at www.astfinancial.com/issuer-investor-services.

        Authorization for electronic direct deposit forms will be processed and will become effective as promptly as practicable after receipt of the form by AST. You may change your designated U.S. bank account for direct deposit or discontinue this feature at any time by submitting to AST a new authorization for electronic direct deposit form, by written instruction to AST or online.

Optional Cash Investments

11.   How do I make an additional investment?

        You may make optional cash investments by choosing among the following options:

S-9


Table of Contents

12.   What are the minimum and maximum amounts for additional investments?

        In addition to increasing your holdings of JBG SMITH shares through the reinvestment of dividends, you may make optional cash investments in JBG SMITH shares at any time. Your optional cash investment must be at least $100, up to a maximum of $300,000 per year. Whether participating through the use of a check, online debit or through the monthly recurring automatic deduction feature, the $100 minimum per transaction applies. If you are not a JBG SMITH shareholder and are a first-time investor in the program, your initial investment must be for at least $250 (or, if you wish to authorize automatic deductions, you must authorize at least three consecutive purchases of at least $100 per transaction). See Question 7 for additional information regarding an initial investment.

        Optional cash investments will be returned to you upon your request, provided that AST receives your request at least two business days prior to the investment date.

Common Share Purchases

13.   What is the source of JBG SMITH shares purchased through the program?

        At JBG SMITH's option, shares may be purchased in the open market through a registered broker-dealer or directly from JBG SMITH. Share purchases in the open market may be made on any stock exchange where JBG SMITH shares are traded or on terms as AST may reasonably determine. Neither JBG SMITH nor any participant will have any authority or power to direct the date, time or price at which JBG SMITH shares may be purchased, or the selection of the broker or dealer through or from whom purchases are to be made.

S-10


Table of Contents

14.   When will JBG SMITH shares be purchased under the program?

        General.    Direct purchases from JBG SMITH of authorized but unissued JBG SMITH shares will be made on the relevant "investment date" as described below. Purchases on the open market will begin on the investment date and generally will be completed the same day, but if market conditions do not permit, the purchases will be completed no later than 30 days from that date, except where completion at a later date is necessary or advisable under any applicable federal securities laws.

        Optional Cash Investments.    AST will normally invest any initial and additional cash investments by check, one-time online debit or by automatic deductions from a U.S. bank account, toward the purchase of JBG SMITH shares no later than five business days after receipt of the investment. AST will determine the actual investment date for initial and additional cash investments.

        Dividend Reinvestments.    The investment date for reinvested cash dividends will be the dividend payment date. If the investment date falls on a date when the NYSE is closed, the investment date will be the next day that the NYSE is open. If AST receives your enrollment form requesting reinvestment of dividends on or before the record date established for a particular dividend, reinvestment will commence with that dividend. We expect that record dates for dividends which may be declared on JBG SMITH shares will be approximately two weeks before the end of each quarter and the related payment dates will be on the last day or next to last day of the quarter.

        If your enrollment form is received after the record date for a particular dividend, the reinvestment of dividends will begin on the dividend payment date following the next record date.

15.   At what price will JBG SMITH shares be purchased?

        For JBG SMITH shares purchased on the open market, AST may combine a participant's funds with funds of other participants and generally will batch purchase types (dividend and optional cash investments) for separate execution by its broker. At AST's discretion these batches may be combined and executed by its broker. AST may also direct its broker to execute each purchase type in several batches throughout a trading day. Depending on the number of shares being purchased and current trading volume in the shares, AST's broker may execute purchases for any batch or batches in multiple transactions and over more than one day. If different purchase types are batched, the price per share of the common shares purchased for each participant's account, whether purchased with funds contributed, dividends or both, shall be the weighted average price of the specific batch for such shares purchased by AST's broker on that investment date.

        For JBG SMITH shares purchased directly from JBG SMITH, the price will be the closing price of the JBG SMITH shares as reported on the New York Stock Exchange Composite Transactions list for that investment date. If no trading in JBG SMITH shares occurs on the NYSE for that date, JBG SMITH will determine your price per share on the basis of market quotations as JBG SMITH deems appropriate.

16.   Will fractional JBG SMITH shares be purchased?

        Yes. If any dividend or optional cash investment is not sufficient to purchase a whole JBG SMITH share, a fractional JBG SMITH share equivalent will be credited to your account. All fractional JBG SMITH shares are rounded to six decimal places.

17.   How are payments with "insufficient funds" handled?

        In the event that any check or other deposit is returned unpaid for any reason, or your predesignated U.S. bank account does not have sufficient funds for an automatic debit, AST will consider the request for investment of that purchase null and void and will immediately remove from your account any JBG SMITH shares already purchased in anticipation of receiving those funds. If the

S-11


Table of Contents

net proceeds from the sale of those shares are insufficient to satisfy the balance of the uncollected amounts, AST may sell additional JBG SMITH shares from your account as necessary to satisfy the uncollected balance. There is a fee for any check or other deposit that is returned unpaid by your bank and for any failed automatic deduction from your predesignated U.S. bank account. This fee will be collected by AST through the sale of the number of JBG SMITH shares from your JBG SMITH Direct account necessary to satisfy the fee.

18.   Will interest be paid on the program accounts?

        No. Interest will not be paid on amounts held pending investment.

19.   Who will hold the additional JBG SMITH shares purchased through JBG SMITH Direct?

        JBG SMITH shares purchased through JBG SMITH Direct are credited in book-entry form to your account on AST's records. The number of JBG SMITH shares (including fractional interests) credited to your account will be shown on each account statement.

        If you wish to pledge JBG SMITH shares credited to your account, you must first request AST to issue a certificate for the JBG SMITH shares. To request a certificate, see Question 20.

Share Certificates and Safekeeping

20.   How may I receive a JBG SMITH share certificate?

        You may obtain a certificate at no cost for some or all of the whole JBG SMITH shares credited to your account at any time by simply requesting AST to issue a certificate for the requested number of JBG SMITH shares. You may make such a request by:

        Certificates will be issued to you and registered in your name. Certificates are normally issued to participants within two business days after receipt of the request. No certificates will be issued for a fractional JBG SMITH share. If you request a certificate for all JBG SMITH shares credited to your account, a certificate will be issued for the whole JBG SMITH shares and a cash payment in the form of a check will be made for any remaining fractional JBG SMITH share. That cash payment will be based upon the then-current market price of JBG SMITH shares, less any service fee, any applicable processing fee and any other costs of sale. Issuance of certificates may be subject to an additional fee. Please contact AST to determine if there is a certificate issuance fee.

        Receiving certificated JBG SMITH shares from your account does not affect your dividend reinvestment option. For example, if you authorized the full dividend reinvestment option, cash dividends with respect to JBG SMITH shares issued in certificate form will continue to be reinvested.

21.   May I add my JBG SMITH share certificate to my JBG SMITH Direct account for safekeeping?

        Yes. You may deposit with AST any JBG SMITH share certificate in your possession and registered in your name for credit to your account as book-entry shares at any time, at no cost. JBG SMITH will pay all fees for this service. This safekeeping feature offers two advantages:

        To combine JBG SMITH shares held in certificate form with JBG SMITH shares held in book-entry form through your JBG SMITH Direct account, you must send your request and your certificates to AST. The certificates should not be endorsed. AST will promptly send you a statement confirming each certificate deposit.

        To insure against potential loss resulting from mailing certificates to AST, you should send your certificates to the address listed in Question 26 by registered mail, return receipt requested, and insured for possible mail loss for 3% of the market value. This represents the approximate cost to you for replacing certificates if they are lost in the mail.

Sale and Transfer of Shares

22.   How may I sell JBG SMITH shares I hold through JBG SMITH Direct?

        You can sell some or all of the shares held in your JBG SMITH Direct account at any time by contacting AST and submitting a sale request. See Question 26 for more information on how to contact AST. A batch order is an accumulation of all sale requests for a security submitted together as a collective request. Batch orders are submitted on each market day, assuming there are sale requests to be processed. Sale instructions for batch orders received by AST will be processed no later than five business days after the date on which the order is received (except where deferral is required under applicable federal or state laws or regulations), assuming the applicable market is open for trading and sufficient market liquidity exists. All sales requests received in writing will be submitted as batch order sales. AST will cause your shares to be sold on the open market within five business days of receipt of your request. To maximize cost savings for batch order sales requests, AST may combine each selling program participant's shares with those of other selling program participants. In every case of a batch order sale, the price to each selling program participant shall be the weighted average sale price obtained by AST's broker for each aggregate order placed by AST and executed by the broker, less a service fee of $15.00 and a processing fee of $0.12 per share sold

        Proceeds are normally paid by check, which are distributed within 24 hours after your sale transaction has settled. You should be aware that the price of JBG SMITH common shares may rise or fall during the period between a request for sale, its receipt by AST, and the ultimate sale on the open market. Instructions for a batch order are binding and may not be rescinded. AST may, for various reasons, require a transaction request to be submitted in writing. Please contact AST to determine if there are any limitations applicable to your particular sale request.

        AST reserves the right to decline to process a sale if it determines, in its sole discretion, that supporting legal documentation is required. In addition, no one will have any authority or power to direct the time or price at which JBG SMITH shares for the program are sold, and no one, other than AST, will select the broker(s) or dealer(s) through or from whom sales are to be made.

23.   Can I transfer JBG SMITH shares that I hold in the program to someone else?

        Yes. You may transfer ownership of some or all of your JBG SMITH shares held through JBG SMITH Direct. You may obtain information about transferring your shares AST's website, www.astfinancial.com/issuer-investor-services, which will guide you through the transfer process, assist you in completing the transfer form, and identify other necessary documentation you may need to provide. Alternatively, you may call AST at 1-866-673-8056 for complete transfer instructions. You will be asked to send to AST written transfer instructions. Your signature on the written transfer instructions must be "Medallion Signature Guaranteed" by a financial institution. Most banks and brokers participate in the Medallion Signature Guarantee program. The Medallion Signature Guarantee program ensures that the individual signing is in fact the owner of the shares to be transferred. A notary is not sufficient.

        You may transfer JBG SMITH shares to new or existing JBG SMITH record shareholders. However, if you transfer less than one whole share, a new JBG SMITH Direct account may not be opened for the transferee. If the transferee is not already a participant in JBG SMITH Direct and you transfer more than one whole share, an account will be opened in the name of the transferee and he or she will automatically be enrolled in the program under the full reinvestment option unless you specify differently. After the transfer has been made, the transferee may change the investment option as described in Question 9.

Termination of Participation

24.   How would I terminate my participation in JBG SMITH Direct?

        You may terminate your participation in JBG SMITH Direct at any time by giving notice to AST. To be effective for any given dividend payment, AST must receive notice before the record date for such dividend payment. If AST receives your request to discontinue dividend reinvestment shortly before, on, or shortly after a record date for a dividend, AST may either pay the dividend in cash or reinvest it under the program on the next investment date on your behalf. If reinvested, AST may sell the JBG SMITH shares purchased and send the proceeds to you, less any service fee, applicable processing fee and any other costs of sale. After processing your request to discontinue dividend reinvestment, any JBG SMITH shares credited to your account under JBG SMITH Direct will continue to be held in book-entry form. Dividends on any JBG SMITH shares held in book-entry form, and on any JBG SMITH shares you hold in certificate form, will be paid in cash by check or direct deposit (at your option). To receive cash dividends by direct deposit, see Question 10.

        Upon termination of your JBG SMITH Direct account, at your request you can either continue to have AST hold your whole shares in your account in book-entry form or you can receive a receive a certificate for the whole shares held for you under JBG SMITH Direct. In both instances you will receive cash payment in the form of a check for any remaining fractional JBG SMITH share. That cash payment will be based upon the then-current market price of JBG SMITH shares, less any service fee, any applicable processing fee and any other costs of sale. Issuance of certificates may be subject to an additional fee. Please contact AST to determine if there is a certificate issuance fee. After AST terminates your account, future dividends will be sent directly to you by check or direct deposit (at your option). To receive cash dividends by direct deposit, see Question 10. Alternatively, if you so direct, AST will sell all whole and fractional shares in your JBG SMITH Direct account. See Question 22 "How may I sell JBG SMITH shares I hold through JBG SMITH Direct?" for more information.

        Rejoining the Plan After Withdrawal.    After you withdraw from JBG SMITH Direct, you may rejoin JBG SMITH Direct at any time by enrolling online, or by filing a new enrollment form with AST, and otherwise complying with the terms of JBG SMITH Direct. However, the JBG SMITH or AST has the right to reject the enrollment form if you repeatedly join and withdraw from the JBG SMITH Direct, or for any other reason. AST's exercise of this right is intended to minimize unnecessary administrative

expenses and to encourage use of the JBG SMITH Direct as a long-term shareholder investment service.

27.   What if JBG SMITH issues a JBG SMITH share dividend or declares a JBG SMITH share split?

        Any JBG SMITH share dividends or split JBG SMITH shares distributed by JBG SMITH on JBG SMITH shares credited to your account or on JBG SMITH shares held by you in the form of certificates will be credited to your account. You will receive a statement indicating the number of JBG SMITH shares or dividends earned as a result of the transaction.

28.   How do I vote my JBG SMITH Direct shares at shareholders' meetings?

        In connection with any meeting of JBG SMITH shareholders, you will receive proxy materials, including a proxy card representing both the JBG SMITH shares for which you hold physical certificates and the whole shares held in book-entry form in your JBG SMITH Direct account.

S-15


Table of Contents

29.   How will JBG SMITH interpret and regulate JBG SMITH Direct and can JBG SMITH Direct be changed?

        We may interpret, regulate and take any other action in connection with JBG SMITH Direct that we deem reasonably necessary in our sole discretion to carry out JBG SMITH Direct. As a participant in JBG SMITH Direct, you will be bound by any actions taken by us or AST.

        While JBG SMITH Direct is intended to continue indefinitely, JBG SMITH reserves the right to suspend or terminate the program at any time. JBG SMITH also reserves the right to make modifications to the program. Enrolled participants will be notified of any such suspension, termination or modification.

30.   Can my JBG SMITH Direct account be terminated?

        AST may terminate your JBG SMITH Direct account if you do not own at least one whole JBG SMITH share. In the event that your program account is terminated for this reason, a check for the cash value of the fractional JBG SMITH share based upon the then-current market price, less any service fee, any processing fee and any other costs of sale will be sent to you and your account will be closed.

        Any questions of interpretation that may arise under the program will be determined by JBG SMITH and JBG SMITH's determination will be final.

31.   Are there any risks associated with JBG SMITH Direct?

        Your investment in common shares purchased under JBG SMITH Direct is no different from any investment in JBG SMITH shares that you hold directly. Neither we nor AST can assure you a profit or protect you against a loss on shares that you purchase. You bear the risk of loss and enjoy the benefits of any gain from market price changes with respect to shares purchased under JBG SMITH Direct. See "Risk Factors."

32.   What are the responsibilities of JBG SMITH and AST under the program?

        Neither JBG SMITH nor AST will be liable for any act or omission to act, which was done in good faith, including any claim of liability arising out of the failure to cease reinvestment of dividends for a participant's account upon the participant's death prior to receipt of notice in writing of the death along with a request to cease dividend reinvestment from a qualified representative of the deceased, the prices at which JBG SMITH shares are purchased or sold for participants' accounts, the times when purchases or sales are made, or fluctuations in the market value of JBG SMITH shares.

        Although JBG SMITH currently contemplates the continuation of quarterly dividends, the payment and amount of dividends is subject to the discretion of JBG SMITH's board of trustees and will depend upon future earnings, financial condition and other factors.

33.   What are the federal income tax consequences of participating in the program?

        A summary of the certain U.S. federal income tax consequences of a shareholders' participation in JBG SMITH Direct is set forth in our Current Report on Form 8-K, filed with the SEC on July 2, 2018 (as amended or supplemented from time to time), and incorporated by reference in this prospectus supplement. The summary in our Current Report on Form 8-K is for general information only and does not constitute tax advice. It does not reflect every possible tax outcome or consequence that could result from participation in JBG SMITH Direct. In addition, it does not reflect state, local or non-U.S. tax consequences that may apply to you based on your particular circumstances and residence. We advise you to consult your own tax advisors to determine the tax consequences particular to your situation, including any applicable state, local or foreign income and other tax consequences that may

S-16

result from your participation in JBG SMITH Direct and your subsequent sale of shares acquired pursuant to JBG SMITH Direct.

34.   Where will notices be sent?

        AST will address all of its notices to you at your last known address. You should notify AST promptly, in writing, of any change of address.

35.   What reports will I receive?

        Easy to read statements of your calendar year-to-date account activity will be sent to you after each transaction, which will simplify your record keeping. Each account statement will show the amount invested, the purchase or sale price, the number of JBG SMITH shares purchased or sold and any applicable fees, as well as any activity associated with JBG SMITH share deposits or certificated withdrawals. Please notify AST promptly either in writing or by telephone if your address changes.

USE OF PROCEEDS

        JBG SMITH will receive proceeds from the sale of common shares that AST purchases directly from us. We will not receive proceeds from the sale of common shares that AST purchases in the open market. We intend to use the proceeds of the sale of any newly issued common shares issued under JBG SMITH Direct for general corporate purposes, which may include paying down indebtedness, and funding our under construction assets and future development opportunities. As of March 31, 2018, borrowings under our revolving credit facility bore interest at a weighted average rate of 2.98% per annum and totaled $116 million. The revolving credit facility has a maturity date of July 2021. As of March 31, 2018, borrowings under our unsecured term loan bore interest at 3.32% per annum and totaled $100 million.

        Since the price of the common shares offered under JBG SMITH Direct is based on future market prices, we are unable to make an advance determination of the price at which common shares will be sold to JBG SMITH Direct participants or the proceeds of such sale.

S-18


Table of Contents

PLAN OF DISTRIBUTION

        Except to the extent AST purchases JBG SMITH shares in open market transactions, JBG SMITH will sell JBG SMITH shares acquired under JBG SMITH Direct directly to you through AST. JBG SMITH shares acquired pursuant to JBG SMITH Direct may be resold in market transactions on any national securities exchange on which JBG SMITH shares trade or in privately negotiated transactions. JBG SMITH shares are currently listed on the NYSE under the trading symbol "JBGS."

        JBG SMITH may sell JBG SMITH shares through JBG SMITH Direct to persons (including brokers or dealers) who, in connection with the resale of JBG SMITH shares, may be considered underwriters. In connection with these types of transactions, compliance with Regulation M under the Exchange Act would be required. The difference between the price such persons who may be deemed to be underwriters pay JBG SMITH for JBG SMITH shares acquired under JBG SMITH Direct and the price at which such JBG SMITH shares are resold, may be deemed to constitute underwriting commissions received by such persons in connection with such transactions. JBG SMITH will not give any person any rights or privileges other than those that the person would be entitled to as a participant in JBG SMITH Direct. JBG SMITH will not enter into any agreement with any person regarding the person's purchase, resale or distribution of JBG SMITH shares.

        Subject to the availability of JBG SMITH shares registered for issuance under JBG SMITH Direct, there is no total maximum number of JBG SMITH shares that can be issued pursuant to JBG SMITH Direct. Except for the specific fees described in Question 4 of this prospectus supplement, you are not required to pay any transaction fees, service fees, processing fees or other charges, in connection with the purchase of JBG SMITH shares under JBG SMITH Direct. You will only have to pay fees in connection with your voluntary sale of JBG SMITH shares from your JBG SMITH Direct account. We will pay all other fees in connection with the purchase of JBG SMITH shares under JBG SMITH Direct. See Questions 4 and 22 for more detailed information.

        JBG SMITH shares may not be available under JBG SMITH Direct in all states. This prospectus supplement does not constitute an offer to sell, or a solicitation of an offer to buy, any JBG SMITH shares or other securities in any state or any other jurisdiction to any person to whom it is unlawful to make such offer in such jurisdiction.

ABOUT THIS PROSPECTUS

        This prospectus is part of a registration statement that we filed with the Securities Exchange Commission (the "SEC"), utilizing a "shelf" registration process. Under this shelf registration process, we may, from time to time, sell any combination of the securities described in this prospectus, in one or more offerings. This prospectus provides you with a general description of the securities that we may offer and is not meant to provide a complete description of each security. As a result, each time we offer securities, to the extent required, a prospectus supplement will be provided, and it will be attached to this prospectus. The prospectus supplement will contain specific information about the terms of that offering, including the specific amounts, prices and terms of the securities being offered. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement, together with additional information described below under the headings "Where You Can Find More Information," "Information Incorporated by Reference" and any additional information you may need before making an investment decision.

        You should rely only on the information provided or incorporated by reference in this prospectus or any applicable prospectus supplement.

We have not authorized anyone to provide you with different or additional information. We are not making an offer to sell these securities in any jurisdiction where the offer or sale of these securities is not permitted. You should not assume that the information appearing in this prospectus, any free writing prospectus and any applicable prospectus supplement prepared by us or the documents incorporated by reference herein or therein is accurate as of any date other than their respective dates. Our business, financial condition, liquidity, results of operations and prospects may have changed since those dates.

        You should read carefully the entire prospectus and any applicable prospectus supplement, as well as the documents incorporated by reference in the prospectus and any applicable prospectus supplement, which we have referred you to in "Information Incorporated by Reference" on page 44 of this prospectus, before making an investment decision.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

        This prospectus, the accompanying prospectus supplement and the documents that we incorporate by reference may include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act") and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). 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 identify such statements by looking for words such as "approximates," "believes," "expects," "anticipates," "estimates," "intends," "plans," "would," "may" or other similar expressions in this prospectus. Although we believe that the expectations reflected in such forward-looking statements are based upon reasonable assumptions, beliefs and expectations, such forward-looking statements are not predictions of future events or guarantees of future performance and our actual results could differ materially from those set forth in the forward-looking statements.

OUR COMPANY

        JBG SMITH Properties ("JBG SMITH" or the "Company") is a real estate investment trust that owns, operates, invests in and develops real estate assets concentrated in leading urban infill submarkets in and around Washington, DC. We own and operate a portfolio of high-quality office and multifamily assets, many of which are amenitized with ancillary retail. In addition, our third-party asset management and real estate services platform provides fee-based real estate services to the legacy funds formerly organized by The JBG Companies and other third parties. References to "our share" refer to our ownership percentage of consolidated and unconsolidated assets in real estate ventures. JBG SMITH operates as a real estate investment trust ("REIT") for U.S. federal income tax purposes.

        As of March 31, 2018, our operating portfolio consists of 68 operating assets comprising 50 office assets totaling over 13.7 million square feet (11.8 million square feet at our share), 14 multifamily assets totaling 6,016 units (4,232 units at our share) and four other assets totaling approximately 765,000 square feet (348,000 square feet at our share). Additionally, we have (i) 10 assets under construction comprising four office assets totaling approximately 1.3 million square feet (1.1 million square feet at our share), five multifamily assets totaling 1,767 units (1,568 units at our share) and one other asset totaling approximately 41,100 square feet (4,100 square feet at our share); and (ii) 43 future development assets totaling approximately 21.3 million square feet (17.9 million square feet at our share) of estimated potential development density.

        JBG SMITH was organized by Vornado Realty Trust ("Vornado") as a Maryland real estate investment trust on October 27, 2016 (capitalized on November 22, 2016). JBG SMITH was formed for the purpose of receiving, via the spin-off on July 17, 2017 (the "separation"), substantially all of the assets and liabilities of Vornado's Washington, DC segment, which operated as Vornado / Charles E. Smith, (the "Vornado Included Assets"). On July 18, 2017, JBG SMITH acquired the management business and certain assets and liabilities of The JBG Companies ("JBG") (the "combination"). The separation and the combination are collectively referred to as the "formation transaction." Unless the context otherwise requires, all references to "we," "us," and "our," refer to the Vornado Included Assets (our predecessor and accounting acquirer) for periods prior to the separation and to JBG SMITH for periods after the separation. Substantially all of our assets are held by, and our operations are conducted through, JBG SMITH Properties LP ("JBG SMITH LP" or the "Operating Partnership"), our operating partnership. We act as general partner of the Operating Partnership and exercise full responsibility, discretion and control over its day-to-day management.

Corporate Information

        We are a Maryland real estate investment trust. The address of our principal executive office is 4445 Willard Avenue, Suite 400, Chevy Chase, Maryland 20815. The telephone number for our principal executive office is (240) 333-3600.

DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

        The following is a summary of the material terms of our shares of beneficial interest that are set forth in our declaration of trust and bylaws. The following summary of the material terms of our shares of beneficial interest does not purport to be complete and is subject to and qualified in its entirety by reference to applicable Maryland law and to our declaration of trust and bylaws, copies of which are filed as exhibits to the registration statement of which this prospectus is a part.

General

        Our authorized shares of beneficial interest consist of 500,000,000 common shares, par value $0.01 per share, and 200,000,000 preferred shares, par value $0.01 per share. Our declaration of trust, as permitted by Maryland law, authorizes our board of trustees, with the approval of a majority of the entire board and without any action on the part of our shareholders, to amend our declaration of trust to increase or decrease the aggregate number of shares that we are authorized to issue or the number of authorized shares of any class or series. The authorized common shares and undesignated preferred shares are generally available for future issuance without further action by our shareholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded.

        Maryland's statutory law governing real estate investment trusts formed under Maryland law and our declaration of trust provide that none of our shareholders will be personally liable by reason of such shareholder's status as a shareholder for any of our obligations.

DESCRIPTION OF COMMON SHARES

Authorization and Issuance

        All common shares offered by this prospectus will be duly authorized and, when issued, will be fully paid and nonassessable. As of June 27, 2018, 117,954,877 common shares were issued and outstanding.

Dividend, Voting and Other Rights of Holders of Common Shares

        The holders of common shares are entitled to receive dividends when, if and as authorized by the board of trustees and declared by us out of assets legally available to pay dividends, if receipt of the dividends complies with the provisions in the declaration of trust restricting the ownership and transfer of our shares and the preferential rights of any other class or series of our shares.

        Subject to the provisions of our declaration of trust regarding the restrictions on ownership and transfer of our common shares and except as may otherwise be specified in the terms of any class or series of shares of beneficial interest, the holders of common shares are entitled to one vote for each share on all matters on which shareholders are entitled to vote, including elections of trustees. There is no cumulative voting in the election of trustees, which means that the holders of a majority of the outstanding common shares can elect all of the trustees then standing for election. Generally, the holders of common shares do not have any conversion, sinking fund, redemption, appraisal or preemptive rights to subscribe to any securities. If we are dissolved, liquidated or wound up, holders of common shares will be entitled to share proportionally in any assets remaining after satisfying (i) the prior rights of creditors, including holders of our indebtedness, and (ii) the aggregate liquidation preference of any preferred shares then outstanding.

        Subject to the provisions of our declaration of trust regarding the restrictions on ownership and transfer of our common shares, common shares have equal dividend, distribution, liquidation and other rights and have no preference or exchange rights. The rights, preferences and privileges of the holders of common shares are subject to, and may be adversely affected by, the rights of the holders of shares of any class or series of preferred shares that we may designate and issue in the future.

Preferred Shares and Share Reclassification

        Under the terms of our declaration of trust, our board of trustees may classify any unissued preferred shares, and reclassify any unissued common shares or any previously classified but unissued preferred shares into other classes or series of shares, including one or more classes or series of shares that have priority over our common shares with respect to distributions or upon liquidation, and we are authorized to issue the newly classified shares. Prior to the issuance of shares of each class or series, the board of trustees is required by the Maryland statute governing real estate investment trusts formed under the laws of that state, which we refer to as the Maryland REIT Law, and our declaration of trust to set, subject to the provisions of our declaration of trust regarding the restrictions on ownership and transfer of our shares, the preferences, conversion or other rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption for each such class or series. These actions may be taken without shareholder approval, unless shareholder approval is required by applicable law, the terms of any other class or series of our shares or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. As of the date hereof, no preferred shares are outstanding. Any preferred shares issued will be subject to ownership and transfer restrictions that are similar to the restrictions applicable to common shares (including a prohibition on owning more than 7.5% of the outstanding preferred shares of any class or series).

Table of Contents

Power to Increase Authorized Shares and Issue Additional Common and Preferred Shares

        We believe that the power of our board of trustees, without shareholder approval, to amend our declaration of trust to increase or decrease the aggregate number of authorized shares or the number of shares in any class or series that we have authority to issue, to issue additional authorized but unissued common shares or preferred shares and to classify or reclassify unissued common shares or preferred shares and thereafter to issue such classified or reclassified shares provides us with flexibility in structuring possible future financings and acquisitions and in meeting other needs which might arise. These actions may be taken without shareholder approval, unless shareholder approval is required by applicable law, the terms of any other class or series of our shares or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Although our board of trustees does not currently intend to do so, it could authorize us to issue additional classes or series of common shares or preferred shares that could, depending upon the terms of the particular class or series, delay, defer or prevent a transaction or a change of control of our company, even if such transaction or change of control involves a premium price for our shareholders or shareholders believe that such transaction or change of control may be in their best interests.

Listing

        Our common shares are listed on the NYSE and trade under the symbol "JBGS."

REIT Qualification

        Under our declaration of trust, the board of trustees may revoke or otherwise terminate our REIT election without shareholder approval if it determines that it is no longer in our best interest to continue to qualify as a REIT.

Certain Provisions of Maryland Law and Our Declaration of Trust and Bylaws

        For a description of certain provisions of Maryland law and our declaration of trust and bylaws that may affect the rights and restrictions related to our common shares, see "Certain Provisions of Maryland Law and Our Declaration of Trust and Bylaws."

Transfer Agent and Registrar

        The transfer agent and registrar for our common shares is American Stock Transfer & Trust Company, LLC.

Restrictions on Ownership

        Holders of common shares will be subject to the ownership restrictions of the declaration of trust. See "Restrictions on Ownership and Transfer."

Our declaration of trust authorizes our board of trustees to classify any unissued preferred shares from time to time into one or more classes or series of preferred shares.

DESCRIPTION OF DEPOSITARY SHARES

General

        We may issue receipts for depositary shares, each of which will represent a fractional interest of a preferred share of a particular series, as specified in the applicable prospectus supplement. Preferred shares of each series represented by depositary shares will be deposited under a separate deposit agreement among us, the depositary named therein and the holders from time to time of the depositary receipts. Subject to the terms of the applicable deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest of a preferred share of a particular series represented by the depositary shares evidenced by such depositary receipt, to all the rights and preferences of the preferred shares represented by such depositary shares (including distribution, voting, conversion, redemption and liquidation rights).

        The depositary shares will be evidenced by depositary receipts issued pursuant to the applicable deposit agreement. Immediately following the issuance and delivery of the preferred shares by us to a preferred share depositary, we will cause such preferred shares depositary to issue, on our behalf, the depositary receipts. Copies of the applicable form of deposit agreement and depositary receipt may be obtained from us upon request, and the statements made hereunder relating to the deposit agreement and the depositary receipts to be issued thereunder are summaries of certain provisions thereof and do not purport to be complete and are subject to, and qualified in their entirety by reference to, all of the provisions of the applicable deposit agreement and related depositary receipts.

Dividends and Other Distributions

        The preferred share depositary will distribute all cash dividends or other cash distributions received in respect of the preferred shares to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of such depositary receipts owned by such holders, subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the preferred shares depositary.

        In the event of a distribution other than in cash, the preferred shares depositary will distribute property received by it to the record holders of depositary receipts entitled thereto, subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the preferred shares depositary, unless the preferred shares depositary determines that it is not feasible to make such distribution, in which case the preferred shares depositary may, with our approval, sell such property and distribute the net proceeds from such sale to such holders.

        No distribution will be made in respect of any depositary share to the extent that it represents any preferred shares converted into other securities.

Withdrawal of Preferred Shares

        Upon surrender of the depositary receipts at the corporate trust office of the applicable preferred shares depositary (unless the related depositary shares have previously been called for redemption or converted into other securities), the holders thereof will be entitled to delivery at such office, to or upon such holder's order, of the number of whole or fractional preferred shares and any money or other property represented by the depositary shares evidenced by such depositary receipts. Holders of depositary receipts will be entitled to receive whole or fractional preferred shares on the basis of the proportion of preferred shares represented by each depositary share as specified in the applicable prospectus supplement, but holders of such preferred shares will not thereafter be entitled to receive depositary shares therefor. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the shares to be withdrawn, the preferred shares depositary will deliver to

12


Table of Contents

such holder at the same time a new depositary receipt evidencing such excess number of depositary shares.

Redemption of Depositary Shares

        Whenever we redeem preferred shares held by the preferred shares depositary, the preferred shares depositary will redeem as of the same redemption date the number of depositary shares representing preferred shares so redeemed, provided we shall have paid in full to the preferred shares depositary the redemption price of the preferred shares to be redeemed plus an amount equal to any accrued and unpaid dividends thereon to the date fixed for redemption. The redemption price per depositary share will be equal to the corresponding proportion of the redemption price and any other amounts per share payable with respect to the preferred shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected pro rata (as nearly as may be practicable without creating fractional depositary shares) or by any other equitable method determined by us that will not result in a violation of the ownership restrictions in our declaration of trust. See "Restrictions on Ownership and Transfer."

        From and after the date fixed for redemption, all dividends in respect of the preferred shares so called for redemption will cease to accrue, the depositary shares so called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary receipts evidencing the depositary shares so called for redemption will cease, except the right to receive any moneys payable upon such redemption and any money or other property to which the holders of such depositary receipts were entitled upon such redemption and surrender thereof to the preferred shares depositary.

Voting of the Preferred Shares

        Upon receipt of notice of any meeting at which the holders of the applicable preferred shares are entitled to vote, the preferred shares depositary will mail the information contained in such notice of meeting to the record holders of the depositary receipts evidencing the depositary shares which represent such preferred shares. Each record holder of depositary receipts evidencing depositary shares on the record date (which will be the same date as the record date for the preferred shares) will be entitled to instruct the preferred shares depositary as to the exercise of the voting rights pertaining to the amount of preferred shares represented by such holder's depositary shares. Generally, the preferred shares depositary will vote the amount of preferred shares represented by such depositary shares in accordance with such instructions, and we will agree to take all reasonable action which may be deemed necessary by the preferred shares depositary in order to enable the preferred shares depositary to do so. The preferred shares depositary will abstain from voting the amount of preferred shares represented by such depositary shares to the extent it does not receive specific instructions from the holders of depositary receipts evidencing such depositary shares. The preferred shares depositary shall not be responsible for any failure to carry out any instruction to vote, or for the manner or effect of any such vote made, as long as any such action or non-action is in good faith and does not result from negligence or willful misconduct of the preferred shares depositary.

Liquidation Preference

        In the event of our liquidation, dissolution or winding up, whether voluntary or involuntary, the holders of each depositary receipt will be entitled to the fraction of the liquidation preference accorded each preferred share represented by the depositary shares evidenced by such depositary receipt, as set forth in the applicable prospectus supplement.

13


Table of Contents

Conversion of Preferred Shares

        The depositary shares, as such, are not convertible into common shares or any of our other securities or property. Nevertheless, if so specified in the applicable prospectus supplement relating to an offering of depositary shares, the depositary receipts may be surrendered by holders thereof to the preferred shares depositary with written instructions to the preferred shares depositary to instruct us to cause conversion of the preferred shares represented by the depositary shares evidenced by such depositary receipts into whole common shares or other preferred shares, and we have agreed that upon receipt of such instructions and any amounts payable in respect thereof, we will cause the conversion thereof utilizing the same procedures as those provided for delivery of preferred shares to effect such conversion. If the depositary shares evidenced by a depositary receipt are to be converted in part only, a new depositary receipt or receipts will be issued for any depositary shares not to be converted. No fractional common shares will be issued upon conversion, and if such conversion would result in a fractional share being issued, an amount will be paid in cash by us equal to the value of the fractional interest based upon the closing price of the common shares on the last business day prior to the conversion.

Amendment and Termination of Deposit Agreement

        The form of depositary receipt evidencing the depositary shares which represent the preferred shares and any provision of the deposit agreement may at any time be amended by agreement between us and the preferred shares depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary receipts or that would be materially and adversely inconsistent with the rights granted to the holders of the related preferred shares will not be effective unless such amendment has been approved by the existing holders of at least two-thirds of the applicable depositary shares evidenced by the applicable depositary receipts then outstanding. No amendment shall impair the right, subject to certain exceptions in the deposit agreement, of any holder of depositary receipts to surrender any depositary receipt with instructions to deliver to the holder the related preferred shares and all money and other property, if any, represented thereby, except in order to comply with law. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective shall be deemed, by continuing to hold such receipt, to consent and agree to such amendment and to be bound by the deposit agreement as amended thereby.

        The deposit agreement may be terminated by us upon not less than 30 days' prior written notice to the preferred shares depositary if (a) such termination is necessary to preserve our status as a REIT or (b) a majority of each series of preferred shares affected by such termination consents to such termination, whereupon the preferred shares depositary shall deliver or make available to each holder of depositary receipts, upon surrender of the depositary receipts held by such holder, such number of whole or fractional preferred shares as are represented by the depositary shares evidenced by such depositary receipts together with any other property held by the preferred shares depositary with respect to such depositary receipts. We will agree that if the deposit agreement is terminated to preserve our status as a REIT, then we will use our best efforts to list the preferred shares issued upon surrender of the related depositary shares on a national securities exchange. In addition, the deposit agreement will automatically terminate if (a) all outstanding depositary shares shall have been redeemed, (b) there shall have been a final distribution in respect of the related preferred shares in connection with our liquidation, dissolution or winding up and such distribution shall have been distributed to the holders of depositary receipts evidencing the depositary shares representing such preferred shares or (c) each related preferred share shall have been converted into our securities not so represented by depositary shares.

Charges of Preferred Shares Depositary

        We will pay all transfer and other taxes and governmental charges arising solely from the existence of the deposit agreement. In addition, we will pay the fees and expenses of the preferred shares depositary in connection with the performance of its duties under the deposit agreement. However, holders of depositary receipts will pay the fees and expenses of the preferred shares depositary for any duties requested by such holders to be performed which are outside of those expressly provided for in the deposit agreement.

Resignation and Removal of Depositary

        The preferred shares depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the preferred shares depositary, any such resignation or removal to take effect upon the appointment of a successor preferred shares depositary. A successor preferred shares depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and that meets certain capital and surplus requirements.

Miscellaneous

        The preferred shares depositary will forward to holders of depositary receipts any reports and communications from us which are received by the preferred shares depositary with respect to the related preferred shares.

        Neither we nor the preferred shares depositary will be liable if it is prevented from or delayed in, by law or any circumstances beyond its control, performing its obligations under the deposit agreement. The obligations of us and the preferred shares depositary under the deposit agreement will be limited to performing their duties thereunder in good faith and without negligence (in the case of any action or inaction in the voting of preferred shares represented by the depositary shares), gross negligence or willful misconduct, and we and the preferred shares depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or preferred shares represented thereby unless satisfactory indemnity is furnished. We and the preferred shares depositary may rely on written advice of counsel or accountants, or information provided by persons presenting preferred shares represented thereby for deposit, holders of depositary receipts or other persons believed in good faith to be competent to give such information, and on documents believed in good faith to be genuine and signed by a proper party.

        If the preferred shares depositary receives conflicting claims, requests or instructions from any holders of depositary receipts, on the one hand, and us, on the other hand, the preferred shares depositary shall be entitled to act on such claims, requests or instructions received from us.

Restrictions on Ownership

        Holders of depositary receipts will be subject to the ownership restrictions of the declaration of trust. See "Restrictions on Ownership and Transfer."

CERTAIN PROVISIONS OF MARYLAND LAW AND OF
OUR DECLARATION OF TRUST AND BYLAWS

        The following description of certain provisions of Maryland law and our declaration of trust and bylaws is only a summary and does not purport to be a complete statement of the relevant provisions. The summary is qualified in its entirety by reference to these documents, which you should read (along with the applicable provisions of Maryland law) for complete information on such provisions. Our declaration of trust and bylaws are filed as exhibits to the registration statement of which this prospectus is a part.

The Board of Trustees

        Our declaration of trust and bylaws provide that the number of our trustees may be established, increased or decreased only by a majority of the entire board of trustees but may not be fewer than the number required by the Maryland REIT Law, which is currently one, nor, unless our bylaws are amended, more than 15, provided, however, that the tenure of office of a trustee will not be affected by any decrease in the number of trustees. Our declaration of trust also provides that, except as may be provided by our board of trustees in setting the terms of any class or series of shares, any vacancy may be filled only by a majority of the remaining trustees, even if the remaining trustees do not constitute a quorum, and any trustee elected to fill a vacancy will hold office for the remainder of the full term of the trusteeship in which the vacancy occurred and until a successor is duly elected and qualifies.

        Our declaration of trust initially divides our board of trustees into three classes. The initial term of the first class of trustees expired at the 2018 annual meeting of shareholders, which was held on May 3, 2018, at which each of the trustees in the first class was elected by shareholders to serve for a two-year term. The initial term of the second and third classes will expire at the second and third annual meetings of shareholders, respectively, held following the formation transaction. Shareholders will elect successors to trustees of the second class for a one-year term at our second annual meeting. Commencing with the third annual meeting of shareholders following the formation transaction, which will be held in 2020, all trustees will be elected annually for a term of one year and shall hold office until the next succeeding annual meeting and until their successors are duly elected and qualify. There is no cumulative voting in the election of trustees. Consequently, at each annual meeting of shareholders, the holders of a majority of our common shares will be able to elect all of our trustees standing for election.

        Under our bylaws, a plurality of all the votes cast at a meeting of shareholders duly called and at which a quorum is present is sufficient to elect a trustee. Notwithstanding such vote requirement, our Corporate Governance Guidelines provide that any nominee in an uncontested election who does not receive a greater number of "for" votes than "withhold" votes shall be elected as a trustee but shall promptly tender his or her offer of resignation to the board of trustees following certification of the vote. The Corporate Governance and Nominating Committee (the "Governance Committee") shall consider the offer to resign and shall recommend to the board of trustees the action to be taken in response to the offer, and the board of trustees shall determine whether or not to accept such resignation. The board of trustees shall promptly disclose its decision and the reasons therefor in a Current Report on Form 8-K furnished to the SEC. At such time as our board of trustees ceases to be classified, our board of trustees will amend our bylaws to provide that a majority of all the votes cast at a meeting of shareholders duly called and at which a quorum is present will be required to elect a trustee, unless the election is contested, in which case a plurality will be sufficient.

        For so long as our board remains classified, this provision could have the effect of making the replacement of incumbent trustees more time-consuming and difficult. Until our third annual meeting, at least two annual meetings of shareholders will generally be required to effect a change in a majority of the board of trustees. The staggered terms of trustees may delay, defer or prevent a tender offer or

18


Table of Contents

an attempt to change control, even though the tender offer or change in control might be in the best interest of our shareholders.

        As described in the section entitled "Proposal One: Election of Trustees" of our Definitive Proxy Statement, which is incorporated herein by reference, Vornado and JBG each appointed six of our 12 trustees (the "Vornado Board Designees" and the "JBG Board Designees," respectively). Pursuant to our bylaws and a master transaction agreement, dated as of October 31, 2016 (the "Master Transaction Agreement"), until July 18, 2019, if any Vornado Board Designee or JBG Board Designee is unable or unwilling to serve or is otherwise no longer serving as a trustee, then the remaining Vornado Board Designees or JBG Board Designees, respectively, may designate a replacement designee reasonably satisfactory to the Governance Committee and the board of trustees, who shall promptly be appointed by our board of trustees to fill the vacancy. Our bylaws and the Master Transaction Agreement also require that, until July 18, 2019, to the extent reasonably practicable, the membership of each of the Audit Committee, Compensation Committee, and Governance Committee shall consist of an equal number of Vornado Board Designees and JBG Board Designees (or their respective replacement designees).

Removal of Trustees

        Our declaration of trust provides that, subject to the rights of holders of one or more classes or series of preferred shares to elect or remove one or more trustees, a trustee may be removed only for cause (defined as conviction of a felony or a final judgment of a court of competent jurisdiction holding that such trustee caused demonstrable, material harm to the trust through willful misconduct, bad faith or active and deliberate dishonesty) and only by the affirmative vote of a majority of the shares then outstanding and entitled to vote generally in the election of trustees. This provision, when coupled with the exclusive power of our board of trustees to fill vacancies on our board of trustees, precludes shareholders from removing incumbent trustees, except for cause and upon a majority affirmative vote, and filling the vacancies created by the removal with their own nominees.

Business Combinations

        Under the Maryland Business Combination Act (the "MBCA"), a "business combination" between a Maryland real estate investment trust and an interested shareholder or an affiliate of an interested shareholder is prohibited for five years after the most recent date on which the interested shareholder becomes an interested shareholder. A business combination includes a merger, consolidation, share exchange, or, in circumstances specified in the statute, an asset transfer, issuance or reclassification of equity securities or recapitalization. An interested shareholder is defined as:

        A person is not an interested shareholder under the statute if the board of trustees approved in advance the transaction by which such person otherwise would have become an interested shareholder. In approving a transaction, the board of trustees may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board of trustees.

19


Table of Contents

        After the five-year prohibition, any business combination between the Maryland real estate investment trust and an interested shareholder generally must be recommended by the board of trustees of the real estate investment trust and approved by the affirmative vote of at least:

        These super-majority vote requirements do not apply if, among other conditions, the real estate investment trust's common shareholders receive a minimum price, as defined under the MBCA, for their shares in the form of cash or other consideration in the same form as previously paid by the interested shareholder for its shares.

        The MBCA permits various exemptions from its provisions, including business combinations that are approved or exempted by the board of trustees before the time that the interested shareholder becomes an interested shareholder.

        The MBCA may have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price or otherwise be in the best interest of the shareholders. The MBCA may discourage others from trying to acquire control and increase the difficulty of consummating any offer.

        As permitted by the Maryland General Corporation Law (the "MGCL"), we have elected in our bylaws to opt out of the MBCA. However, we cannot assure you that our board of trustees will not opt to be subject to such provisions in the future, including opting to be subject to such provisions retroactively.

Control Share Acquisitions

        The Maryland Control Share Acquisition Act (the "MCSAA") provides that control shares of a Maryland real estate investment trust acquired in a control share acquisition have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter. Shares owned by the acquiring person, by officers or by employees who are trustees of the real estate investment trust are excluded from shares entitled to vote on the matter. "Control shares" are voting shares which, if aggregated with all other shares owned by the acquiring person or in respect of which the acquiring person is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiring person to exercise voting power in electing trustees within one of the following ranges of voting power:

        Control shares do not include shares that the acquiring person is then entitled to vote as a result of having previously obtained shareholder approval or shares acquired directly from the real estate investment trust. A control share acquisition means the acquisition of control shares, subject to certain exceptions.

        A person who has made or proposes to make a control share acquisition may compel the board of trustees of the real estate investment trust to call a special meeting of shareholders to be held within 50 days of the demand to consider the voting rights of the control shares. The right to compel the

20


Table of Contents

calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the meeting. If no request for a meeting is made, the real estate investment trust may itself present the question at any shareholders meeting.

        If voting rights are not approved at the meeting or if the acquiring person does not deliver an acquiring person statement as required by the MCSAA, then the real estate investment trust may redeem for fair value any or all of the control shares, except those for which voting rights have previously been approved. The right of the real estate investment trust to redeem control shares is subject to certain conditions and limitations. Fair value is determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquiring person or, if a meeting of shareholders is held at which the voting rights of the shares are considered and not approved, as of the date of such meeting. If voting rights for control shares are approved at a shareholders meeting and the acquiring person becomes entitled to vote a majority of the shares entitled to vote, all other shareholders may exercise appraisal rights. The fair value of the shares as determined for purposes of appraisal rights may not be less than the highest price per share paid by the acquiring person in the control share acquisition.

        The MCSAA does not apply to (a) shares acquired in a merger, consolidation or share exchange if the real estate investment trust is a party to the transaction, or (b) acquisitions approved or exempted by the declaration of trust or bylaws of the real estate investment trust.

        Our bylaws contain a provision exempting from the MCSAA any and all acquisitions by any person of our shares. There can be no assurance that this provision will not be amended or eliminated at any time in the future.

Approval of Extraordinary Trust Action; Amendment of Declaration of Trust and Bylaws

        Under the Maryland REIT Law, a Maryland real estate investment trust generally cannot dissolve, amend its declaration of trust or merge with or convert into another entity, unless the action is advised by its board of trustees and approved by the affirmative vote of shareholders holding at least two-thirds of the shares entitled to vote on the matter. However, a Maryland real estate investment trust may provide in its declaration of trust for approval of these matters by a lesser percentage, but not less than a majority of all of the votes entitled to be cast on the matter. Except for certain amendments described in our declaration of trust that require only approval by our board of trustees, our declaration of trust provides for approval of any of these matters by the affirmative vote of not less than a majority of all of the votes entitled to be cast on such matters. However, the partnership agreement of our Operating Partnership provides that certain extraordinary transactions will require, in addition to the consent of our shareholders, "partnership approval" from the limited partners of JBG  SMITH LP, as described below under the section entitled "Partnership Agreement."

        Our bylaws provide that any provision of our bylaws may be amended, altered or repealed, and new bylaws adopted by the board of trustees or by the affirmative vote of holders of shares of JBG SMITH representing not less than a majority of all the votes entitled to be cast on the matter. Until July 18, 2019, certain amendments to our bylaws relating to the composition of our board of trustees require the approval of the majority of the entire board of trustees, including a majority of each of the JBG Board Designees and Vornado Board Designees.

Exclusive Forum

        Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (a) any derivative action or proceeding brought in our right or on our behalf, (b) any action asserting a claim of breach of any duty owed by any of our trustees or officers or other employees or agents to us or to our shareholders, (c) any action asserting a claim against us or any of our trustees or officers or other employees or agents arising pursuant to any provision of the

21


Table of Contents

Maryland REIT Law or our declaration of trust or bylaws or (d) any action asserting a claim against us or any of our trustees or officers or other employees that is governed by the internal affairs doctrine shall be the Circuit Court for Baltimore City, Maryland (and any shareholder that is a party to any action or proceeding pending in such Court shall cooperate in having the action or proceeding assigned to the Business & Technology Case Management Program), or, if that Court does not have jurisdiction, the United States District Court for the District of Maryland, Baltimore Division.

Advance Notice of Trustee Nominations and New Business

        Our bylaws provide that with respect to an annual meeting of shareholders, nominations of persons for election to the board of trustees and the proposal of business to be considered by shareholders may be made only (i) pursuant to our notice of the meeting, (ii) by or at the direction of our board of trustees or (iii) by a shareholder who is a shareholder of record both at the time of giving the advance notice required by the bylaws and at the time of the meeting, who is entitled to vote at the meeting and who has complied with the advance notice procedures of the bylaws. With respect to special meetings of shareholders, only the business specified in our notice of the meeting may be brought before the meeting. Nominations of persons for election to the board of trustees at a special meeting may be made only (i) by the board of trustees or (ii) provided that the special meeting has been called in accordance with the bylaws for the purpose of electing trustees, by a shareholder who is a shareholder of record both at the time of giving the advance notice required by the bylaws and at the time of the meeting, who is entitled to vote at the meeting and who has complied with the advance notice provisions of the bylaws.

Maryland Unsolicited Takeover Act

        Subtitle 8 of Title 3 of the MGCL, commonly referred to as the Maryland Unsolicited Takeovers Act ("MUTA"), permits a Maryland real estate investment trust with a class of equity securities registered under the Exchange Act and at least three independent trustees to elect to be subject, by provision in its declaration of trust or bylaws or a resolution of its board of trustees and notwithstanding any contrary provision in the declaration of trust or bylaws, to any or all of the following five provisions:

        Our declaration of trust prohibits us from electing to be subject to any provision of MUTA unless such election is first approved by our shareholders by the affirmative vote of at least a majority of the votes entitled to vote on the matter. Through provisions in our declaration of trust and bylaws unrelated to Subtitle 8, (1) we have a classified board until the third annual meeting of shareholders following the formation transaction and (2) we vest in the board of trustees the exclusive power to fix the number of trusteeships, subject to limitations set forth in our declaration of trust and bylaws.

Anti-takeover Effect of Certain Provisions of Maryland Law and of Our Declaration of Trust and Bylaws

        The business combination provisions and, if the applicable provision in our bylaws is rescinded, the control share acquisition provisions of Maryland law, the provisions of our declaration of trust on removal of trustees and the advance notice provisions of our bylaws could delay, defer or prevent a transaction or a change in control that might involve a premium price for holders of our common shares or otherwise be in their best interest.

Shareholder Meetings

        Our bylaws provide that annual meetings of our shareholders may only be held each year at a date, time and place determined by our board of trustees. Special meetings of shareholders may be called by the chairman of our board of trustees, our chief executive officer, our president, our board of trustees and our shareholders that hold a majority of all of the votes entitled to be cast on the matter. Only matters set forth in the notice of a special meeting of shareholders may be conducted at such a meeting.

Shareholder Action by Written Consent

        Under our declaration of trust, any action required to be taken at any annual or special meeting of shareholders may be taken without a meeting, without prior notice and without a vote if (i) a unanimous consent setting forth the action is given in writing or by electronic transmission by all shareholders entitled to vote on the matter or (ii) the action is advised and submitted to the shareholders for approval by our board of trustees and a consent in writing or by electronic transmission is given by shareholders entitled to cast not less than the minimum number of votes that would be required to take the action at a meeting of our shareholders.

Limitation of Liability and Indemnification of Trustees and Officers

        Maryland law permits a Maryland real estate investment trust to include in its declaration of trust a provision limiting or eliminating the liability of its trustees and officers to the real estate investment trust and its shareholders for money damages except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) active and deliberate dishonesty that is established by a final judgment and which is material to the cause of action. Our declaration of trust includes such a provision eliminating such liability to the maximum extent permitted by Maryland law.

        Our declaration of trust and bylaws obligate us, to the fullest extent permitted by Maryland law in effect from time to time, to indemnify and to pay or reimburse reasonable expenses in advance of final disposition of a proceeding, without requiring a preliminary determination of the trustee's or officer's ultimate entitlement to indemnification, to (i) any present or former trustee or officer who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity, or (ii) any individual who, while serving as our trustee or officer and at our request, serves or has served as a director, trustee, officer, partner, member or manager of another corporation, real estate investment trust, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity. Our declaration of trust and bylaws also permit us, with the approval of the board of trustees, to indemnify and advance expenses to any person who served one of our predecessors in any of the capacities described above and to any of our employees, agents or predecessors.

        Maryland law requires a Maryland real estate investment trust (unless its declaration of trust provides otherwise, which ours does not) to indemnify a trustee or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason

23


Table of Contents

of his or her service in that capacity. Maryland law permits a real estate investment trust to indemnify its present and former trustees and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the trustee or officer was material to the matter giving rise to the proceeding and (i) was committed in bad faith or (ii) was the result of active and deliberate dishonesty, (b) the trustee or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the trustee or officer had reasonable cause to believe that the act or omission was unlawful. However, under Maryland law, a Maryland real estate investment trust may not indemnify for an adverse judgment in a suit by or in the right of the real estate investment trust or for a judgment of liability on the basis that personal benefit was improperly received, unless in either case a court orders indemnification and then only for expenses. In addition, Maryland law permits a real estate investment trust to advance reasonable expenses to a trustee or officer upon the real estate investment trust's receipt of (a) a written affirmation by the trustee or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the real estate investment trust and (b) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed by the real estate investment trust if it shall ultimately be determined that the standard of conduct was not met.

        We entered into indemnification agreements with each of our trustees and executive officers that provide for indemnification to the maximum extent permitted by Maryland law.

        Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our officers, trustees or controlling persons pursuant to the foregoing provisions or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy and, therefore, unenforceable. We have purchased liability insurance for the purpose of providing a source of funds to pay the indemnification described above.

Business Opportunities

        Our declaration of trust provides that our trustees who are also trustees, officers, employees or agents of Vornado or any of Vornado's affiliates (each such trustee, a "Covered Person") shall have no duty to communicate or present any business opportunity to us, and we renounce any potential interest or expectation in, or right to be offered or to participate in, such business opportunity and waives to the maximum extent permitted from time to time by Maryland law any claim against a Covered Person arising from the fact that he or she does not present, communicate or offer any such business opportunity to us or any of our subsidiaries or pursues such business opportunity or facilitates the pursuit of such business opportunity by others; provided, however, that the foregoing shall not apply in a case in which a Covered Person is presented with a business opportunity in writing expressly in his or her capacity as our trustee. Accordingly, to the maximum extent permitted from time to time by Maryland law and except to the extent such business opportunity is presented to a Covered Person in writing expressly in his or her capacity as our trustee, (a) no Covered Person is required to present, communicate or offer any business opportunity to us and (b) any Covered Person, on his or her own behalf or on behalf of Vornado, shall have the right to hold and exploit any business opportunity, or to direct, recommend, offer, sell, assign or otherwise transfer such business opportunity to any person or entity other than us.

Proxy Access

        Our bylaws permit a shareholder, or group of up to 20 shareholders, owning at least 3% of our outstanding common shares, continuously for at least three years, to nominate and include in the our proxy statement for an annual meeting of shareholders, trustee nominees constituting up to the greater of two nominees or 20% of the board of trustees, provided that the shareholder(s) and the trustee nominee(s) satisfy the requirements specified in the bylaws.

PARTNERSHIP AGREEMENT

        The summary of the limited partnership agreement of JBG SMITH LP, as amended and restated, is subject to and qualified in its entirety by reference to applicable to our limited partnership agreement, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part.

        JBG SMITH LP, our Operating Partnership, is a Delaware limited partnership. We are the sole general partner of this partnership. As of March 31, 2018, we owned, directly or indirectly, approximately 85.6% of the partnership interests in our Operating Partnership. In the future, we may issue additional interests in JBG SMITH LP to third parties.

Management

        Pursuant to the partnership agreement of JBG SMITH LP, we, as the general partner, have full, exclusive and complete responsibility for and discretion in the management, operation and control of the partnership, including the ability to cause the partnership to enter into certain major transactions, including acquisitions, developments and dispositions of assets, borrowings and refinancings of existing indebtedness, and the merger, consolidation, reorganization or other combination of the Operating Partnership or its subsidiaries with or into another person. No limited partner may take part in the operation, management or control of the business of our Operating Partnership by virtue of being a holder of limited partnership units.

        We may not be removed as general partner of the partnership. Upon our bankruptcy or dissolution, the limited partnership shall be dissolved automatically unless, within 90 days after the entry of a final and nonappealable judgment ruling that the general partner is insolvent or a final and nonappealable order for relief against us, a majority in interest of the remaining partners consent in writing to continue the business of the partnership and to the appointment of a substitute general partner.

Fiduciary Responsibilities

        The partnership agreement contains provisions that expressly limit the duties, fiduciary or otherwise, that we, as general partner, owe to the limited partners of the Operating Partnership. Any decisions or actions taken or not taken in accordance with the terms of the partnership agreement will not constitute a breach of any duty owed to the Operating Partnership or its limited partners by law or equity, fiduciary or otherwise. Pursuant to the partnership agreement, we act on behalf of the Operating Partnership and its equityholders, and on behalf of our shareholders, and generally are under no obligation to consider or give priority to the separate interests of the limited partners in the Operating Partnership (including, without limitation, the tax consequences to such limited partners) in deciding whether to cause the Operating Partnership to take (or decline to take) any actions.

Outside Activities of JBG SMITH

        Substantially all of our assets consist of our ownership of limited partnership units of the Operating Partnership. The partnership agreement prohibits us from directly or indirectly entering into or conducting any material business other than in connection with the ownership, acquisition and disposition of limited partnership units of the Operating Partnership and the management of the business of the Operating Partnership. In addition, we may not, without the consent of the holders of a majority of limited partnership units (other than us and our affiliates), own assets other than limited partnership interests in the Operating Partnership and certain other permitted assets.

Transferability of Interests

        The partnership agreement provides that we may not transfer our interest as a general partner except in connection with a transaction permitted under the partnership agreement. We may not withdraw from the partnership or transfer all or any portion of our limited partnership interest (whether by sale, disposition, statutory merger or consolidation, liquidation or otherwise) except (i) in connection with a merger, consolidation or other combination with or into another person following the consummation of which the equityholders of the surviving entity are substantially identical to our shareholders, (ii) with the consent of a majority of our limited partners (excluding us and any limited partners majority owned, directly or indirectly, by us), (iii) to one or more of our controlled affiliates or (iv) in connection with an "extraordinary transaction" as described below. Upon any such transfer, the transferee will become the successor general partner under the partnership agreement.

        We may not engage in a merger, consolidation or other combination with or into another person, a sale of all or substantially all of our assets, or a reclassification, recapitalization or a change in outstanding shares (except for changes in par value, or from par value to no par value, or as a result of a subdivision or combination of our common shares), which we refer to collectively as an "extraordinary transaction," unless (i) we receive "partnership approval" (as defined below) of the extraordinary transaction, in the event that partners will receive consideration for their operating partnership units as described in clause (ii) and we are required to seek approval of our shareholders of the extraordinary transaction, or if we would be required to obtain such shareholder approval but for the fact that a tender offer has been accepted by a sufficient number of shareholders to permit consummation of the extraordinary transaction without such approval, and (ii) each partner receives or has the right to receive in the extraordinary transaction cash, securities or other property for each operating partnership unit owned by such partner in the same form as, and equal to the greatest per-share amount paid to, our shareholder (or equal to a proportional amount, if the common limited partnership units ("OP Units") are no longer redeemable for shares on a one-for-one basis).

        To obtain "partnership approval," we must obtain the consent of our limited partners (including us and any limited partners majority owned, directly or indirectly, by us) representing a percentage interest in JBG SMITH LP that is equal to or greater than the percentage of our outstanding common shares required (or, if there is no shareholder vote with respect to such extraordinary transaction because a tender offer shall have been accepted with respect to a sufficient number of our common shares to permit consummation of the extraordinary transaction without shareholder approval, the percentage of our outstanding common shares that would have been required in the absence of a tender offer) to approve the extraordinary transaction. For purposes of calculating whether this percentage interest in JBG SMITH LP has been obtained, we and any limited partners majority owned, directly or indirectly, by us will be deemed to have provided consent for our partnership units solely in proportion to the percentage of our common shares approving the extraordinary transaction (or, in the case of a tender offer, the percentage of our common shares with respect to which such tender offer shall have been accepted). The "partnership approval" requirement will be satisfied, with respect to such extraordinary transaction when the sum of (i) the percentage interest of limited partners consenting to the extraordinary transaction, plus (ii) the product of (a) the percentage of the outstanding partnership units held by us or by limited partners majority owned, directly or indirectly, by us multiplied by (b) the percentage of our outstanding common shares (or of votes cast, as the case may be) that were cast in favor of the extraordinary transaction (or with respect to which such tender offer shall have been accepted) equals or exceeds the percentage required (or that would have been required in the absence of such tender offer) for our common shareholders to approve the extraordinary transaction.

26


Table of Contents

        The partnership agreement prohibits the transfer (including the sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition) of all or any portion of the limited partnership units without our consent, which we may give or withhold in our sole discretion, except for (i) transfers to affiliates of the transferor limited partner, which are permissible without our consent, and (ii) transfers by an incapacitated limited partner, in which case such incapacitated limited partner may transfer all or any portion of its partnership units, and (iii) certain other permitted transfers.

        The partnership agreement contains other restrictions on transfer if, among other things, that transfer would adversely affect our ability to qualify as a REIT or would subject us to any additional taxes under the Internal Revenue Code of 1986, as amended (the "Code").

Capital Contributions

        Under the partnership agreement, we are obligated to contribute the proceeds of any offering of shares as additional capital to our Operating Partnership. The general partner is authorized to cause the Operating Partnership to issue partnership interests for less than fair market value if we conclude in good faith that such issuance is in both the partnership's and our best interests.

        The partnership agreement provides that we may make additional capital contributions, including assets, to the partnership in exchange for additional partnership units. If we contribute additional capital to the partnership and receive additional partnership interests for such capital contribution, our percentage interests will be increased on a proportionate basis based on the amount of such additional capital contributions and the value of the partnership at the time of such contributions. Conversely, the percentage interests of the other limited partners will be decreased on a proportionate basis. In addition, if we contribute additional capital to the partnership and receive additional partnership interests for such capital contribution, the capital accounts of the partners will be adjusted upward or downward to reflect any unrealized gain or loss attributable to our assets as if there were an actual sale of such assets at the fair market value thereof. Limited partners have no preemptive right to make additional capital contributions.

        The Operating Partnership could also issue preferred partnership interests in connection with the acquisitions of property or otherwise. Any such preferred partnership interests have priority over common limited partnership interests with respect to distributions from the partnership, including the partnership interests that our wholly owned subsidiaries may own.

Redemption Rights

        Subject to certain specified notice requirements, periodic limits and minimum thresholds set forth in the partnership agreement, a limited partner may generally exercise a redemption right to redeem OP Units at any time beginning the later of (1) August 1, 2018, and (2) twelve months from the date of the issuance of the limited partnership units held by the limited partner, subject to certain limitations in terms of timing and the total number of OP Units that can be redeemed in a single year. In addition, we may reduce or waive the holding period.

        Further, if we give the limited partners notice of our intention to make an extraordinary distribution of cash or property to our shareholders or effect a merger, a sale of all or substantially all of our assets, or any other similar extraordinary transaction, each limited partner may exercise its unit redemption right, regardless of the length of time it has held its OP Units.

        A limited partner may not exercise the unit redemption right for fewer than 1,000 OP Units or, if the limited partner holds fewer than 1,000 OP Units, all of the OP Units held by that limited partner.

27


Table of Contents

The redeeming partner will have no right to receive any distributions paid on or after the redemption date with respect to those OP Units redeemed.

        Unless we elect to assume and perform the Operating Partnership's obligation with respect to the unit redemption right, as described below, a limited partner exercising a unit redemption right will receive cash from the Operating Partnership in an amount equal to the market value of our common shares for which the OP Units would have been redeemed if we had assumed and satisfied the Operating Partnership's obligation by paying with our common shares, as described below. The market value of our common shares for this purpose will be equal to the closing price of our common shares on the NYSE on the first business day occurring after the 60th day following the day on which we received the redemption notice.

        In our sole discretion, we may elect to assume and perform the Operating Partnership's obligation to acquire the OP Units being redeemed in exchange for either cash in the amount specified above or a number of our common shares equal to the number of OP Units offered for redemption, adjusted as specified in the partnership agreement to take into account prior share dividends or any subdivisions or combinations of our common shares.

        Notwithstanding the foregoing, a limited partner may not exercise the redemption right to the extent that the delivery of common shares on the redemption date would (i) be prohibited, as determined in our sole discretion, under our declaration of trust, (ii) cause the acquisition of common shares by the limited partner to be "integrated" with any other distribution of common shares for purposes of complying with the Securities Act (iii) would otherwise be prohibited under applicable federal or state securities laws or regulations, or (iv) would violate certain other restrictions, including those related to our intent to prevent the partnership from being treated as a "publicly traded partnership." We may, in our sole discretion, waive these prohibitions.

        Subject to certain exceptions, holders of LTIP Units (as defined below) may not exercise the redemption right for LTIP Units unless and until the LTIP Units are converted into OP Units, provided that the redemption right may not be exercised with respect to any OP Unit issued upon conversion of an LTIP Unit until on or after the date that is two years after the date on which the LTIP Unit was issued. In addition, subject to certain exceptions, holders of Formation Units (as defined below) may not exercise the redemption right for Formation Units unless and until the Formation Units are converted into LTIP Units that subsequently are converted into OP Units, provided that the redemption right may not be exercised with respect to any OP Unit issued upon such conversions until on or after the date that is two years after the date on which the Formation Unit was issued.

Operations

        The partnership agreement requires the partnership to be operated in a manner that enables us to satisfy the requirements for being classified as a REIT, to avoid the imposition of federal income and excise tax liability and to ensure that the partnership will not be classified as a "publicly traded partnership" taxable as a corporation under Section 7704 of the Code.

        In addition to the administrative and operating costs and expenses incurred by the partnership, the partnership pays all of our administrative costs and expenses. These expenses are treated as expenses of the partnership and generally include all expenses relating to our continuity of existence, all expenses relating to offerings and registration of securities, all expenses associated with the preparation and filing of any of our periodic reports under federal, state or local laws or regulations, all expenses associated with our compliance with laws, rules and regulations promulgated by any regulatory body and all of our other operating or administrative costs incurred in the ordinary course of our business on behalf of the partnership.

Issuance of Additional Partnership Interests

        We, as general partner, are authorized to cause the partnership to issue additional limited partnership units or other partnership interests to its partners, including us and our affiliates, or other persons without the approval of any limited partners. These limited partnership units may be issued in one or more classes or in one or more series of any class, with designations, preferences and relative, participating, optional or other special rights, powers and duties, including rights, powers and duties senior to one or more other classes of partnership interests (including limited partnership units held by us), as determined by us in our sole and absolute discretion without the approval of any limited partner, subject to limitations described below.

        No limited partnership unit or interest may be issued to us as general partner or limited partner unless:

Compensatory Partnership Units

        In addition to the OP Units, the partnership may issue compensatory partnership interests in the form of LTIP units, which, in general, are a special class of limited partnership units of the partnership that are structured in a manner intended to qualify as "profits interests" for federal income tax purposes (the "LTIP Units"). LTIP Units may be subject to vesting requirements as determined prior to grant. LTIP Units subject to time-based vesting requirements are referred to by us as "Time-Based LTIP Units." Generally, LTIP Units receive the same quarterly (or other period) per-unit profit distributions as the outstanding OP Units beginning as of the date specified in the vesting agreement pursuant to which the LTIP Units are issued (the "Distribution Participation Date"). Net income and net loss is allocated to each LTIP Unit from the Distribution Participation Date for such LTIP Unit in amounts per LTIP Unit equal to the amounts allocated per OP Unit for the same period, with certain exceptions, including special allocations as provided under the partnership agreement.

        The partnership maintains a capital account balance for each LTIP Unit as of the date of grant, and a corresponding "Book-Up Target," which will generally correspond to the capital account balance of the general partner on a per-unit basis, and the Book-Up Target will be reduced by certain specified allocations and forfeitures until the LTIP Unit capital account balance has reached parity with the capital account balance of the general partner on a per-unit basis (as provided in the partnership agreement), and the Book-Up Target equals zero. The partnership will maintain at all times a one-to-one correspondence between LTIP Units and OP Units for conversion, distribution and other purposes, except as provided in the partnership agreement, and will make corresponding adjustments to the LTIP Units to maintain such correspondence upon the occurrence of certain specified adjustment events. A holder of LTIP Units has the right to convert all or a portion of vested LTIP Units into OP Units, which are then subsequently redeemable for common shares, as provided in the partnership

agreement. Notwithstanding the foregoing, in no event may a holder of LTIP Units convert a vested LTIP Unit the Book-Up Target of which has not been reduced to zero.

        LTIP Units are not entitled to the redemption right described above, but any OP Units into which LTIP Units are converted are entitled to this redemption right. LTIP Units, generally, vote with the OP Units and do not have any separate voting rights except in connection with actions that would materially and adversely affect the rights of the LTIP Units.

        Under the 2017 Omnibus Plan, participants may earn awards in the form of LTIP Units based on the achievement of certain financial goals (the "Performance-Based LTIP Units"), which may include absolute total shareholder return (which we refer to as TSR) and TSR relative to our peer group over a specified measurement period, or other performance metrics.

        Performance-Based LTIP Units are valued by reference to the value of a common share. The employment conditions, the length of the period for vesting and other applicable conditions and restrictions of Performance-Based LTIP Unit awards, including computation of financial metrics and/or achievement of pre-established performance goals, are established prior to grant. Such Performance-Based LTIP Unit awards may provide the holder with rights to distributions or dividend equivalents prior to vesting. It is anticipated that net income and net loss will be allocated to each Performance-Based LTIP Unit from the date of issuance until the Distribution Participation Date for such Performance-Based LTIP Unit in amounts per Performance-Based LTIP Unit equal to 10% of the amounts allocated per OP Unit for the same period, with certain exceptions, including special allocations as provided under the partnership agreement.

        Like LTIP Units, Performance-Based LTIP Unit awards are structured in a manner intended to qualify as "profits interests" for federal income tax purposes, meaning that, under current law, no income will be recognized by the recipient upon grant or vesting, and we will not be entitled to any deduction. The holder of the Performance-Based LTIP Units is entitled to receive distributions with respect to such Performance-Based LTIP Units to the extent that may be provided for in the partnership agreement, as modified by the award agreement, and is not entitled to receive distributions prior to the applicable Distribution Participation Date.

Other Partnership Units

        "Formation Units" are a class of partnership interests in the partnership that were generally granted to certain individuals in connection with the formation transaction. Formation Units are intended to qualify as "profits interests" for federal income tax purposes and are designed to have economics comparable to stock options in that, assuming vesting, they allow the recipient to realize value above a threshold level set at the time of award to be equal to 100% of the then-fair market value of a common share. The value of vested Formation Units is realized through conversion into a number of LTIP Units, and subsequent conversion into OP Units determined on the basis of how much the value of a common share has increased since the award date. The conversion ratio between Formation Units and OP Units, which starts out at zero, is the quotient of (i) the excess of the value of a common share on the conversion date above the per share value at the time the Formation Unit was granted over (ii) the value of a common share as of the date of conversion. This is similar to a "cashless exercise" of stock options, whereby the holder receives a number of shares equal in value to the difference between the full value of the total number of shares for which the option is being exercised and the total exercise price. Like options, Formation Units have a finite term over which their value is allowed to increase and during which they may be converted into LTIP Units (and in turn, OP Units).

30


Table of Contents

        Because the Formation Units are outstanding partnership interests, until conversion to vested LTIP Units, holders of Formation Units will receive special allocations of liquidating gains and liquidating losses as provided under the partnership agreement. Holders of Formation Units will not receive distributions or allocations of net income or net loss prior to vesting and conversion to vested LTIP Units and, as a result, will be required to fund their tax liability relating to any special allocations they receive with respect to their Formation Units from other sources. However, upon conversion of Formation Units to vested LTIP Units, the holder will be entitled to receive a distribution per unit equal to 10% of the per unit distributions received by holders of OP Units during the period from the grant date of the Formation Units through the date of such conversion, or such other fraction as specified in the applicable award agreement. Upon conversion of Formation Units to vested LTIP Units, the holder will receive allocations of net income and net loss such that the ratio of (i) the total amount of net income or net loss with respect to each Formation Unit in such taxable year to (ii) the total amount distributed to that Formation Unit with respect to such period is equal (as nearly as practicable) to the ratio of (i) to (ii) with respect to the general partner's OP Units for such taxable year, with certain exceptions, including any special allocations as provided under the partnership agreement. As a result, assuming that the partnership makes distributions equal to or greater than its taxable income, holders of Formation Units should receive distributions that equal or exceed the amount of any allocations of taxable income they have been allocated.

Preemptive Rights

        Except to the extent expressly granted by the partnership in an agreement other than the partnership agreement, no person or entity, including any partner of the partnership, has any preemptive, preferential or other similar right with respect to additional capital contributions or loans to the partnership or the issuance or sale of any OP Units or other partnership interests.

Distributions

        The partnership agreement provides that the partnership will make cash distributions in amounts and at such times as determined by us in our sole discretion, to us and other limited partners in accordance with the respective percentage interests of the partners in the partnership. Unless otherwise specifically provided for in the partnership agreement (including with respect to the ranking of any units as senior in preference or in priority to other units) or in the terms established for a new class or series of partnership interests in accordance with the partnership agreement, no partnership interest is entitled to a distribution in preference to any other partnership interest. A partner will not in any event receive a distribution of available cash with respect to a limited partnership unit for a quarter or shorter period if the partner is entitled to receive a distribution out of that same available cash with respect to a common share for which that limited partnership unit has been exchanged or redeemed.

        We will make reasonable efforts, as determined by us in our sole discretion and consistent with our qualification as a REIT, to cause the partnership to distribute available cash in an amount sufficient to enable us to pay shareholder dividends that will satisfy the requirements to qualify as a REIT and to avoid any federal income or excise tax liability.

        Upon liquidation of the partnership, after payment of, or adequate provisions for, debts and obligations of the partnership, including any partner loans, any remaining assets of the partnership will be distributed to us and the other limited partners with positive capital accounts in accordance with the respective positive capital account balances of the partners.

Allocations

        Profits and losses of the partnership (including depreciation and amortization deductions) for each fiscal year generally will be allocated to us and the other limited partners in accordance with the

31


Table of Contents

respective percentage interests of the partners in the partnership. All of the foregoing allocations are subject to compliance with the provisions of Sections 704(b) and 704(c) of the Code and Treasury regulations promulgated thereunder.

Amendments

        Amendments to the partnership agreement may be proposed only by the general partner. The general partner has the power, subject to certain exceptions, to amend the partnership agreement without the consent of the limited partners. However, the partnership agreement may not be amended with respect to any partner adversely affected by such amendment without the consent of such limited partner if such amendment would convert a limited partner's interest into a general partner's interest, modify the limited liability of a general partner, or amend certain specified sections of the partnership agreement, including the unit redemption right of the limited partners and the distribution rights of and allocations to the limited partners (except in connection with the creation or issuance of new or additional partnership interests or as otherwise permitted by the partnership agreement). In addition, certain specified sections of the partnership agreement, including restrictions on the issuance of limited partnership units and restrictions on the transfers by us of limited partnership units, may not be amended without the consent of a majority of the holders of limited partnership units (other than us and our affiliates).

Exculpation and Indemnification of the General Partner

        The partnership agreement provides that none of the general partner, its affiliates nor any of their respective directors, trustees, officers, shareholders, partners, members, employees, representatives or agents (each of which we refer to as a "covered person") will be liable to the partnership or to any of its partners as a result of errors in judgment or of any act or omission, if such covered person's conduct did not constitute bad faith, gross negligence or willful misconduct.

        In addition, the partnership agreement requires our Operating Partnership to indemnify the general partner and its trustees, officers, shareholders, partners, members, employees, representatives or agents from and against any and all claims that relate to the operations of our Operating Partnership or the general partner in which any such indemnitee may be involved, or is threatened to be involved, as a party or otherwise, except to the extent such indemnitee acted in bad faith or with gross negligence or willful misconduct.

        No indemnitee may subject any partner of our Operating Partnership to personal liability with respect to this indemnification obligation as this indemnification obligation will be satisfied solely out of the assets of the partnership.

Term

        The partnership shall continue until it is dissolved, whether upon (i) the general partner's bankruptcy or dissolution or withdrawal (unless the limited partners elect to continue the partnership), (ii) the sale or other disposition of all or substantially all of the assets of the partnership, (iii) an election by us in our capacity as the general partner on or after January 1, 2068 or (iv) entry of a decree of judicial dissolution of the partnership.

RESTRICTIONS ON OWNERSHIP AND TRANSFER

The Beneficial Ownership Limit

        For us to maintain our qualification as a REIT under the Code, not more than 50% of the value of our outstanding shares of beneficial interest may be owned, directly or indirectly, by five or fewer individuals at any time during the last half of a taxable year, and the shares of beneficial interest must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months, or during a proportionate part of a shorter taxable year (except, in each case, with respect to the first taxable year for which an election to be taxed as a REIT is made). The Code defines "individuals" to include some entities for purposes of the preceding sentence. All references to a shareholder's ownership of common shares in this section "—The Beneficial Ownership Limit" assume application of the applicable attribution rules of the Code under which, for example, a shareholder is deemed to own shares owned by his or her spouse.

        The declaration of trust contains several provisions that restrict the ownership and transfer of our shares that are designed to safeguard us against loss of our REIT status. These provisions also seek to deter non-negotiated acquisitions of, and proxy fights for, us by third parties. The declaration of trust contains a limitation that restricts, with some exceptions, shareholders from owning more than 7.5% (in value or number of shares, whichever is more restrictive) of the outstanding shares of any class or series, including our common shares. We refer to this percentage as the "beneficial ownership limit."

        Shareholders should be aware that events other than a purchase or other transfer of common shares can result in ownership, under the applicable attribution rules of the Code, of common shares in excess of the beneficial ownership limit. For instance, if two shareholders, each of whom owns 6% of the outstanding common shares, were to marry, then after their marriage both shareholders would be deemed to own 12% of the outstanding common shares, which is in excess of the beneficial ownership limit. Similarly, if a shareholder who is treated as owning 6% of the outstanding common shares purchased a 50% interest in a corporation which owns 10% of the outstanding common shares, then the shareholder would be deemed to own 11% of the outstanding common shares immediately after such purchase. You should consult your tax advisors concerning the application of the attribution rules of the Code in your particular circumstances.

Closely Held and General Restriction on Ownership

        In addition, common shares may not be transferred if, as a result of such transfer, more than 50% in value of the outstanding common shares would be owned by five or fewer individuals or if such transfer would otherwise cause us to fail to qualify as a REIT.

The Constructive Ownership Limit

        Under the Code, rental income received by a REIT from persons in which the REIT is treated, under the applicable attribution rules of the Code, as owning a 10% or greater interest does not constitute qualifying income for purposes of the income requirements that REITs must satisfy. For these purposes, a REIT is treated as owning any shares owned, under the applicable attribution rules of the Code, by a person that owns 10% or more of the value of the outstanding shares of the REIT. The attribution rules of the Code applicable for these purposes are different from those applicable with respect to the beneficial ownership limit. All references to a shareholder's ownership of common shares in this section "—The Constructive Ownership Limit" assume application of the applicable attribution rules of the Code.

        To ensure that our rental income will not be treated as nonqualifying income under the rule described in the preceding paragraph, and thus to ensure that we will not inadvertently lose our REIT status as a result of the ownership of shares by a tenant, or a person that holds an interest in a tenant,

33


Table of Contents

the declaration of trust contains an ownership limit that restricts, with some exceptions, shareholders from constructively owning, directly or indirectly, more than 7.5% (in value or number of shares, whichever is more restrictive) of the outstanding shares of any class or series. We refer to this 7.5% ownership limit as the "constructive ownership limit."

        Shareholders should be aware that events other than a purchase or other transfer of shares may result in ownership, under the applicable attribution rules of the Code, of shares in excess of the constructive ownership limit. As the attribution rules that apply with respect to the constructive ownership limit differ from those that apply with respect to the beneficial ownership limit, the events other than a purchase or other transfer of shares which may result in share ownership in excess of the constructive ownership limit may differ from those which may result in share ownership in excess of the beneficial ownership limit. You should consult your tax advisors concerning the application of the attribution rules of the Code in your particular circumstances.

Automatic Transfer to a Trust If the Ownership Limits Are Violated

        The declaration of trust provides that a transfer of shares of any class or series that would otherwise result in ownership, under the applicable attribution rules of the Code, of shares in excess of the beneficial ownership limit or the constructive ownership limit would cause our shares of beneficial interest to be beneficially owned by fewer than 100 persons, would result in us being "closely held" (within the meaning of Section 856(h) of the Code) or would otherwise cause us to fail to qualify as a REIT, will be void and the purported transferee will acquire no rights or economic interest in the shares. In addition, our declaration of trust provides that, if the provisions causing a transfer to be void do not prevent a violation of the restrictions mentioned in the preceding sentence, the shares that would otherwise be owned, under the applicable attribution rules of the Code, in excess of the beneficial ownership limit or the constructive ownership limit, or that would cause us to be "closely held" or otherwise fail to qualify as a REIT, will be automatically transferred to one or more charitable trusts (each, a "charitable trust") for the benefit of one or more charitable beneficiaries, appointed by us, effective as of the close of business on the business day prior to the date of the relevant transfer.

        Shares held in a charitable trust will be issued and outstanding shares. Pursuant to our declaration of trust, the purported transferee will have no rights in the shares held in a charitable trust and will not benefit economically from ownership of any shares held in the charitable trust, will have no rights to dividends or other distributions and will have no right to vote or other rights attributable to the shares held in the charitable trust. Instead, our declaration of trust provides that the trustee of the charitable trust will have all voting rights and rights to dividends or other distributions with respect to shares held in the charitable trust, to be exercised for the exclusive benefit of the charitable beneficiary. Under our declaration of trust, any dividend or other distribution paid prior to the discovery by us that the shares have been transferred to the charitable trust shall be paid by the holder of such dividend or other distribution to the trustee upon demand and any dividend or other distribution authorized but unpaid shall be paid when due to the trustee. Subject to Maryland law, the trustee of the charitable trust has the authority (i) to rescind as void any vote cast by a purported transferee prior to the discovery by us that the shares have been transferred to the charitable trust and (ii) to recast such vote in accordance with the desires of the trustee acting for the benefit of the charitable beneficiary. However, if we have already taken irreversible trust action, then the trustee will not have the authority to rescind and recast the vote.

        Under our declaration of trust, within 20 days of receiving notice from us that shares have been transferred to the charitable trust, the trustee of the charitable trust shall sell the shares held in the charitable trust to a person or persons, designated by the trustee, whose ownership of the shares will not violate the restrictions on ownership and transfer noted above. Upon such sale, our declaration of trust provides that the interest of the charitable beneficiary in the shares sold terminates and the trustee of the charitable trust is required to distribute the net proceeds of the sale to the purported

34


Table of Contents

transferee and to the charitable beneficiary as follows: the purported transferee will receive the lesser of (i) the price paid by the purported transferee for the shares or, if the purported transferee did not purchase the shares for the market price (as defined in our declaration of trust) in connection with the event causing the shares to be held in the charitable trust, the market price of the shares on the date of the event causing the shares to be held in the charitable trust and (ii) the price per share received by the trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares held in the charitable trust. The trustee of the charitable trust may reduce the amount payable to the purported transferee by the amount of dividends and distributions which have been paid to the purported transferee and are owed by the purported transferee to the charitable trust, as described above. Any net sales proceeds in excess of the amount payable to the purported transferee will be paid immediately to the charitable beneficiary. If, prior to the discovery by us that common shares have been transferred to the charitable trust, such shares are sold by a purported transferee, then (1) such shares shall be deemed to have been sold on behalf of the charitable trust and (2) to the extent that the purported transferee received an amount for such shares that exceeds the amount that such purported transferee would have been entitled to receive if such shares had been sold by the charitable trust, such excess shall be paid to the trustee upon demand.

        Our declaration of trust provides that any shares transferred to the charitable trust are deemed to have been offered for sale to us, or our designee. The price at which we, or our designee, may purchase the shares transferred to the charitable trust will be equal to the lesser of (i) the price paid by the purported transferee for the shares or, if the purported transferee did not purchase the shares for the market price in connection with the event causing the shares to be held in the charitable trust, the market price of the shares on the date of the event causing the shares to be held in the charitable trust and (ii) the market price of the shares on the date that we, or our designee, accepts the offer. Upon a sale to us, the interest of the beneficiary in the shares sold will terminate and the trustee will distribute the net proceeds of the sale to the purported transferee and the trustee will distribute any dividends or other distributions held by the trustee with respect to such shares to the beneficiary.

        We may reduce the amount payable to the purported transferee by the amount of dividends and other distributions that have been paid to the purported transferee and are owed by the purported transferee to the charitable trust, as described above. Our right to accept the offer described above exists for as long as the charitable trust has not otherwise sold the shares held in trust.

        In addition, if our board of trustees determines that a transfer or other event has occurred that would violate the restrictions on ownership and transfer of shares described above, the board of trustees may take such action as it deems advisable to refuse to give effect to or to prevent such transfer, including, but not limited to, causing us to redeem shares, refusing to give effect to the transfer on our books or instituting proceedings to enjoin the transfer.

Other Provisions Concerning the Restrictions on Ownership

        Our board of trustees, in its sole discretion, may prospectively or retroactively exempt persons from the beneficial ownership limit and the constructive ownership limit and increase or decrease the beneficial ownership limit and constructive ownership limit for one or more persons, if in each case the board of trustees obtains such representations, covenants and undertakings as the board of trustees may deem appropriate in order to conclude that such exemption or modification will not cause us to lose our status as a REIT. In addition, the board of trustees may require such opinions of counsel, affidavits, undertakings or agreements or a ruling from the Internal Revenue Service as it may deem necessary or advisable in order to determine or ensure our status as a REIT, and any such exemption or modification may be subject to such conditions or restrictions as the board of trustees may impose.

        The foregoing restrictions on transfer and ownership will not apply if the board of trustees determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a

35


Table of Contents

REIT or that compliance with any of the foregoing restrictions is no longer required for REIT qualification.

        All persons who own, directly or by virtue of the applicable attribution rules of the Code, more than 1.0% (or such lower percentage as required by the Code or the regulations promulgated thereunder) of the outstanding shares of any class or series must give a written notice to us containing the information specified in the declaration of trust by January 31 of each year. In addition, each shareholder will be required to disclose to us upon demand any information that we may request, in good faith, to determine our status as a REIT or to comply with Treasury regulations promulgated under the REIT provisions of the Code.

        The transfer and ownership restrictions described above may have the effect of precluding acquisition of control of us unless our board of trustees determines that maintenance of REIT status is no longer in our best interests or that compliance with any of the foregoing restrictions is no longer required for REIT qualification.

BOOK-ENTRY SECURITIES

        We may issue the securities offered by means of this prospectus in whole or in part in book-entry form, meaning that beneficial owners of the securities will not receive certificates representing their ownership interests in the securities, except in the event the book-entry system for the securities is discontinued. If securities are issued in book entry form, they will be evidenced by one or more global securities that will be deposited with, or on behalf of, a depositary identified in the applicable prospectus supplement relating to the securities. The Depository Trust Company is expected to serve as depository. Unless and until it is exchanged in whole or in part for the individual securities represented thereby, a global security may not be transferred except as a whole by the depository for the global security to a nominee of such depository or by a nominee of such depository to such depository or another nominee of such depository or by the depository or any nominee of such depository to a successor depository or a nominee of such successor. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. The specific terms of the depositary arrangement with respect to a class or series of securities that differ from the terms described here will be described in the applicable prospectus supplement.

        Unless otherwise indicated in the applicable prospectus supplement, we anticipate that the following provisions will apply to depository arrangements.

        Upon the issuance of a global security, the depository for the global security or its nominee will credit on its book-entry registration and transfer system the respective principal amounts of the individual securities represented by such global security to the accounts of persons that have accounts with such depository, who are called "participants." Such accounts shall be designated by the underwriters, dealers or agents with respect to the securities or by us if the securities are offered and sold directly by us. Ownership of beneficial interests in a global security will be limited to the depository's participants or persons that may hold interests through such participants. Ownership of beneficial interests in the global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the applicable depository or its nominee (with respect to beneficial interests of participants) and records of the participants (with respect to beneficial interests of persons who hold through participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to own, pledge or transfer beneficial interest in a global security.

        So long as the depository for a global security or its nominee is the registered owner of such global security, such depository or nominee, as the case may be, will be considered the sole owner or holder of the securities represented by such global security for all purposes under the applicable instrument defining the rights of a holder of the securities. Except as provided below or in the applicable prospectus supplement, owners of beneficial interest in a global security will not be entitled to have any of the individual securities of the series represented by such global security registered in their names, will not receive or be entitled to receive physical delivery of any such securities in definitive form and will not be considered the owners or holders thereof under the applicable instrument defining the rights of the holders of the securities.

        Payments of amounts payable with respect to individual securities represented by a global security registered in the name of a depository or its nominee will be made to the depository or its nominee, as the case may be, as the registered owner of the global security representing such securities. None of us, our officers and board members or any trustee, paying agent or security registrar for an individual series of securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security for such securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

        We expect that the depository for a series of securities offered by means of this prospectus or its nominee, upon receipt of any payment of principal, premium, interest, dividend or other amount in

37


Table of Contents

respect of a permanent global security representing any of such securities, will immediately credit its participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security for such securities as shown on the records of such depository or its nominee. We also expect that payments by participants to owners of beneficial interests in such global security held through such participants will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in "street name." Such payments will be the responsibility of such participants.

        If a depository for a series of securities is at any time unwilling, unable or ineligible to continue as depository and a successor depository is not appointed by us within 90 days, we will issue individual securities of such series in exchange for the global security representing such series of securities. In addition, we may, at any time and in our sole discretion, subject to any limitations described in the applicable prospectus supplement relating to such securities, determine not to have any securities of such series represented by one or more global securities and, in such event, will issue individual securities of such series in exchange for the global security or securities representing such series of securities.

PLAN OF DISTRIBUTION

        Unless otherwise set forth in a prospectus supplement accompanying this prospectus, we may sell the offered securities to one or more underwriters or dealers for public offering and sale by them, or we may sell the offered securities to investors directly or through agents, which agents may be affiliated with us. We may sell securities directly to investors on our own behalf in those jurisdictions where we are authorized to do so. Direct sales to investors may be accomplished through subscription offerings or through subscription rights distributed to our shareholders. In connection with subscription offerings or the distribution of subscription rights to shareholders, if all of the underlying offered securities are not subscribed for, we may sell such unsubscribed offered securities to third parties directly or through agents and, in addition, whether or not all of the underlying offered securities are subscribed for, we may concurrently offer additional offered securities to third parties directly or through agents, which agents may be affiliated with us. Any underwriter, dealer or agent involved in the offer and sale of the offered securities will be named in the applicable prospectus supplement.

        The distribution of the offered securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices at the time of sale, such as an "at the market offering," or at negotiated prices, any of which may represent a discount from the prevailing market price. We also may, from time to time, authorize underwriters or dealers acting as our agents to offer and sell the offered securities upon the terms and conditions set forth in the applicable prospectus supplement. In connection with the sale of offered securities, underwriters may receive compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of offered securities for whom they may act as agent. Underwriters may sell offered securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent.

        Our common shares may also be sold in one or more of the following transactions: (a) block transactions (which may involve cross transactions) in which a broker-dealer may sell all or a portion of such shares as agent, but may position and resell all or a portion of the block as principal to facilitate the transaction; (b) purchases by any such broker-dealer as principal, and resale by such broker-dealer for its own account pursuant to a prospectus supplement; (c) a special offering, an exchange distribution or a secondary distribution in accordance with applicable NYSE or other stock exchange, quotation system or over-the-counter market rules; (d) ordinary brokerage transactions and transactions in which any such broker-dealer solicits purchasers; (e) sales "at the market" to or through a market maker or into an existing trading market, on an exchange or otherwise, for such shares and (f) sales in other ways not involving market makers or established trading markets, including direct sales to purchasers.

        Any underwriting compensation paid by us to underwriters or agents in connection with the offering of offered securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in the applicable prospectus supplement. Dealers and agents participating in the distribution of the offered securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the offered securities may be deemed to be underwriting discounts and commissions, under the Securities Act.

        Underwriters, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward civil liabilities, including liabilities under the Securities Act. Any such indemnification agreements will be described in the applicable prospectus supplement. Unless otherwise set forth in an accompanying prospectus supplement, the obligations of any underwriters to purchase any of the securities will be subject to certain conditions precedent, and the underwriters will be obligated to purchase all of such securities, if any are purchased.

39


Table of Contents

        If so indicated in the applicable prospectus supplement, we will authorize underwriters or dealers acting as our agents to solicit offers by institutions to purchase offered securities from us at the public offering price set forth in such prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in such prospectus supplement. Each contract will be for an amount not less than, and the aggregate principal amount of offered securities sold pursuant to contracts shall be not less nor more than, the respective amounts stated in the applicable prospectus supplement. Institutions with whom contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions, and other institutions but will in all cases be subject to our approval.

        Contracts will not be subject to any conditions except the purchase by an institution of the offered securities covered by its contracts shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which such institution is subject, and if the offered securities are being sold to underwriters, we shall have sold to such underwriters the total principal amount of the offered securities less the principal amount of the securities covered by contracts. Some of the underwriters and their affiliates may be customers of, engage in transactions with and perform services for us and our subsidiaries in the ordinary course of business. The underwriters and other agents will not have any responsibility with regard to the validity or performance of these delayed delivery contracts.

        In connection with the offering of the securities hereby, certain underwriters, and selling group members and their respective affiliates may engage in transactions that stabilize, maintain or otherwise affect the market price of the applicable securities. Such transactions may include stabilization transactions effected in accordance with Rule 104 of Regulation M promulgated by the SEC pursuant to which such persons may bid for or purchase securities for the purpose of stabilizing their market price. The underwriters in an offering of securities may also create a "short position" for their account by selling more securities in connection with the offering than they are committed to purchase from us. In such case, the underwriters could cover all or a portion of such short position by either purchasing securities in the open market following completion of the offering of such securities or by exercising any over-allotment option granted to them by us. In addition, the managing underwriter may impose "penalty bids" under contractual arrangements with other underwriters, which means that they can reclaim from an underwriter (or any selling group member participating in the offering) for the account of the other underwriters, the selling concession with respect to securities that are distributed in the offering but subsequently purchased for the account of the underwriters in the open market. Any of the transactions described in this paragraph or comparable transactions that are described in any accompanying prospectus supplement may result in the maintenance of the price of the securities at a level above that which might otherwise prevail in the open market. None of such transactions described in this paragraph or in an accompanying prospectus supplement are required to be taken by any underwriters and, if they are undertaken, may be discontinued at any time.

        We may sell the securities in exchange in whole or part for consideration other than cash. This consideration may consist of services or products, whether tangible or intangible, and including services or products we may use in our business; outstanding debt or equity securities of the Company or one or more of its subsidiaries; debt or equity securities or assets of other companies, including in connection with investments, joint ventures or other strategic transactions, or acquisitions; release of claims or settlement of disputes; and satisfaction of obligations, including obligations to make payments to distributors or other suppliers and payment of interest on outstanding obligations. We may sell the securities as part of a transaction in which outstanding debt or equity securities of the Company or one or more of our subsidiaries are surrendered, converted, exercised, canceled or transferred.

        Our common shares are listed on the NYSE under the symbol "JBGS." Any new securities that issue, other than common shares, will be new issues of securities with no established trading market and may or may not be listed on a national securities exchange, quotation system or over-the-counter market. Any underwriters or agents to or through which securities are sold by us may make a market in such securities, but such underwriters or agents will not be obligated to do so and any of them may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of or trading market for any securities sold by us.
