**<u>EXPLANATORY NOTE</u>**

This report combines the Quarterly Reports on Form 10-Q for the period ended September 30, 2025 of BXP, Inc. and Boston Properties Limited Partnership. Unless stated otherwise or the context otherwise requires, references to "BXP" mean BXP, Inc. (formerly known as Boston Properties, Inc.), a Delaware corporation that has elected to be taxed as a real estate investment trust ("REIT"), and references to "BPLP" and the "Operating Partnership" mean Boston Properties Limited Partnership, a Delaware limited partnership. BPLP is the entity through which BXP conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. BXP is the sole general partner and also a limited partner of BPLP. As the sole general partner of BPLP, BXP has exclusive control of BPLP's day-to-day management. Therefore, unless stated otherwise or the context requires, references to the "Company," "we," "us" and "our" refer collectively to BXP, BPLP and those subsidiaries consolidated by BXP.

As of September 30, 2025, BXP owned an approximate 89.6% ownership interest in BPLP. The remaining approximate 10.4% interest was owned by limited partners. The other limited partners of BPLP (1) contributed their direct or indirect interests in properties to BPLP in exchange for common units of limited partnership interest in BPLP or (2) received long-term incentive plan units of BPLP pursuant to BXP's Stock Option and Incentive Plans, or both. Under the limited partnership agreement of BPLP, unitholders may present their common units of BPLP for redemption at any time (subject to covenants agreed upon at the time of issuance of the units that may restrict such right for a period of time, generally one year from issuance). Upon presentation of a common unit for redemption, BPLP must redeem the unit for cash equal to the then value of a share of BXP's common stock. In lieu of a cash redemption by BPLP, however, BXP may elect to acquire any common units so tendered by issuing shares of BXP common stock in exchange for the common units. If BXP so elects, its common stock will be exchanged for common units on a one-for-one basis. This one-for-one exchange ratio is subject to specified adjustments to prevent dilution. BXP generally expects that it will elect to issue its common stock in connection with each such presentation for redemption rather than having BPLP pay cash. With each such exchange or redemption, BXP's percentage ownership in BPLP will increase. In addition, whenever BXP issues shares of its common stock other than to acquire common units of BPLP, BXP must contribute any net proceeds it receives to BPLP and BPLP must issue to BXP a number of common units of BPLP that equals the number of shares of BXP common stock so issued. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT.

The Company believes that combining the Quarterly Reports on Form 10-Q of BXP and BPLP into this single report:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhances investors' understanding of BXP and BPLP by enabling them to view the business as a whole in the same manner as management views and operates the business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• eliminates duplicative disclosure and provides a more concise and readable presentation because a substantial portion of the disclosure applies to both BXP and BPLP; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

The Company believes it is important to understand the few differences between BXP and BPLP in the context of how BXP and BPLP operate as a consolidated company. The financial results of BPLP are consolidated into the financial statements of BXP. BXP does not have any other significant assets, liabilities or operations, other than its investment in BPLP, nor does it have employees of its own. BPLP, not BXP, generally executes all significant business relationships other than transactions involving the securities of BXP. BPLP holds substantially all of the assets of BXP, including ownership interests in subsidiaries and joint ventures. BPLP conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity issuances by BXP, which are contributed to the capital of BPLP in exchange for common or preferred units of partnership in BPLP, as applicable, BPLP generates all remaining capital required by the Company's business. These sources include working capital, net cash provided by operating activities, borrowings under its credit facilities, the issuance of secured and unsecured debt and equity securities and proceeds received from the disposition of certain properties and interests in joint ventures.

Shareholders' equity, partners' capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of BXP and BPLP. The limited partners of BPLP are accounted for as partners' capital in BPLP's financial statements and as noncontrolling interests in BXP's financial statements. The noncontrolling interests in BPLP's financial statements include the interests of unaffiliated partners in various

consolidated partnerships. The noncontrolling interests in BXP's financial statements include the same noncontrolling interests in BPLP and limited partners of BPLP. The differences between shareholders' equity and partners' capital result from differences in the equity issued by each of BXP and BPLP.

In addition, the consolidated financial statements of BXP and BPLP differ in total real estate assets resulting from previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor redemptions of common units of BPLP. This accounting resulted in a step-up of the real estate assets of BXP at the time of such redemptions, resulting in a difference between the net real estate of BXP as compared to BPLP of approximately $228.0 million, or 1.1% at September 30, 2025, and a corresponding difference in depreciation expense, impairment losses and gains on sales of real estate upon the sale of these properties having an allocation of the real estate step-up. The acquisition accounting was nullified on a prospective basis beginning in 2009 as a result of the Company's adoption of a new accounting standard requiring any subsequent redemptions to be accounted for solely as an equity transaction.

To help investors better understand the key differences between BXP and BPLP, the following items in this report present information separately for BXP and BPLP:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Item 1. Financial Statements (unaudited), which includes the following specific disclosures for BXP and BPLP:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 10. Stockholders' Equity / Partners' Capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 11. Segment Information; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Note 12. Earnings Per Share / Common Unit; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Liquidity and Capital Resources, includes information specific to each entity, where applicable.

This report also includes separate Part I - Item 4. Controls and Procedures and Part II - Item 2. Unregistered Sales of Equity Securities and Use of Proceeds sections for each of BXP and BPLP, as well as separate Exhibits 31 and 32 certifications for each of BXP and BPLP.

**BXP, INC. AND BOSTON PROPERTIES LIMITED PARTNERSHIP**

**NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS**

**1. Organization** 

BXP is a fully integrated, self-administered and self-managed REIT. BXP is the sole general partner of BPLP, its operating partnership, and at September 30, 2025, owned an approximate 89.6% (89.7% at December 31, 2024) general and limited partnership interest in BPLP. Unless stated otherwise or the context requires, the "Company" refers to BXP and its subsidiaries, including BPLP and its consolidated subsidiaries. Partnership interests in BPLP include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• common units of partnership interest (also referred to as "OP Units") and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• long term incentive units of partnership interest (also referred to as "LTIP Units")

Unless specifically noted otherwise, all references to OP Units exclude units held by BXP. A holder of an OP Unit may present the OP Unit to BPLP for redemption at any time (subject to covenants agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, BPLP is obligated to redeem the OP Unit for cash equal to the value of a share of common stock of BXP ("Common Stock"). In lieu of such cash redemption, BXP may elect to acquire the OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that BXP owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock.

The Company uses LTIP Units as a form of time-based, restricted equity compensation and as a form of performance-based equity compensation for employees, and it has previously granted LTIP Units in the form of (1) 2012 outperformance plan awards ("2012 OPP Units") and (2) 2013 - 2025 multi-year, long-term incentive program awards (also referred to as "MYLTIP Units"), each of which, upon the satisfaction of certain performance-based and time-based vesting conditions, is convertible into one OP Unit. The three-year measurement periods for the 2012 OPP Units and the 2013 - 2022 MYLTIP Units have ended and BXP's total stockholder return ("TSR") was sufficient for employees to earn and therefore become eligible to vest in a portion of the awards. Unless and until they are earned, the rights, preferences and privileges of the 2023 - 2025 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units and the 2013 - 2022 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 2023 - 2025 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units and the earned 2013 - 2022 MYLTIP Units), whether vested or not, receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Notes 9 and 13).

*Properties*

At September 30, 2025, the Company owned or had joint venture interests in a portfolio of 187 commercial real estate properties (the "Properties") aggregating approximately 54.6 million net rentable square feet of primarily office properties, including eight properties under construction/redevelopment totaling approximately 3.5 million net rentable square feet. At September 30, 2025, the Properties consisted of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 163 office properties (including four properties under construction/redevelopment);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 14 retail properties (including one property under construction);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• nine residential properties (including three properties under construction); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• one hotel.

**2. Summary of Significant Accounting Policies** 

BXP does not have any other significant assets, liabilities or operations, other than its investment in BPLP, nor does it have employees of its own. BPLP, not BXP, generally executes all significant business relationships other than transactions involving securities of BXP. All majority-owned subsidiaries and joint ventures over which the Company has financial and operating control and variable interest entities ("VIEs") in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. Accordingly, the Company's share of the earnings of these joint ventures and companies is included in consolidated net income (loss).

The accompanying interim financial statements are unaudited; however, the financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting solely of normal recurring matters) necessary for a fair statement of the financial statements for these interim periods have been included. The results of operations for the interim periods are not necessarily indicative of the results to be obtained for other interim periods or for the full fiscal year. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosure required by GAAP. These financial statements should be read in conjunction with the Company's financial statements and notes thereto contained in the Company's Annual Report in the Company's Form 10-K for its fiscal year ended December 31, 2024.

The Company bases its estimates on historical experience and on various other assumptions that it considers to be reasonable under the circumstances, including the impact of extraordinary events, the results of which form the basis for making significant judgments about the carrying values of assets and liabilities, assessments of future collectability, and other areas of the financial statements that are impacted by the use of estimates. Actual results may differ from these estimates under different assumptions or conditions.

***Variable Interest Entities (VIEs)***

Consolidated VIEs are those for which the Company is considered to be the primary beneficiary of a VIE. The primary beneficiary is the entity that has a controlling financial interest in the VIE, which is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE's performance and (2) the obligation to absorb losses or the right to receive the returns from the VIE that could potentially be significant to the VIE. The assets of each VIE are only available to satisfy such VIE's respective liabilities. The Company has identified 11 entities that are VIEs as of September 30, 2025 and has determined that it is the primary beneficiary for eight of these entities as of September 30, 2025.

<u>Consolidated Variable Interest Entities</u>

As of September 30, 2025, BXP has identified eight consolidated VIEs, including BPLP. Excluding BPLP, the consolidated VIEs consisted of (i) the following six in-service properties: 767 Fifth Avenue (the General Motors Building), 7 Times Square (formerly Times Square Tower), 601 Lexington Avenue, 300 Binney Street, Atlantic Wharf Office Building and 100 Federal Street and (ii) 290 Binney Street, which is currently under development.

The Company consolidates these VIEs because it is the primary beneficiary. The third parties' interests in these consolidated entities (excluding BPLP's interest) are reflected as noncontrolling interests in property partnerships in the accompanying consolidated financial statements (See Note 9).

In addition, BXP's only significant asset is its investment in BPLP and, consequently, substantially all of BXP's assets and liabilities are the assets and liabilities of BPLP.

<u>Variable Interest Entities Not Consolidated</u> 

As of September 30, 2025, BXP has identified three unconsolidated joint venture entities that are classified as VIEs. The CAB 290 Coles Venture LLC, CAB 290 Coles Holdco LLC, and 17 Hartwell JV LLC joint ventures are VIEs because they do not have sufficient equity at risk. In addition, the Company does not consolidate the entities as it does not have the power to direct the activities that, when taken together, most significantly impact the VIEs' performance and, therefore, the Company is not considered to be the primary beneficiary.

***Exchangeable Debt***

On September 29, 2025, BPLP issued $1.0 billion aggregate principal amount of 2.00% Exchangeable Senior Notes due 2030 (the "Notes") in a private placement (see Note 6). The Company accounts for the Notes in accordance with Accounting Standards Codification ("ASC") 470-20, Debt with Conversion and Other Options (after the adoption of Accounting Standards Update ("ASU") 2020-06, Debt - Debt and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Contracts in an Entity's Own Equity ("ASU 2020-06")). The exchange feature embedded within the Notes is eligible for an exception from derivative accounting because it is indexed to BXP's stock. BPLP is the entity through which BXP conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. As

such, the exchange feature embedded within the Notes meets the equity classification under ASC 815-40, Derivatives and Hedging—Contracts in Entity's Own Equity, therefore, the exchange feature is not bifurcated.

At each reporting period, the Company calculates the effect of the Notes on its dilutive earnings per common share / common unit using the if-converted method (See Note 12). Concurrently with the pricing of the Notes, the Company entered into capped call transactions ("Capped Call Transactions") with certain financial institutions. The Capped Call Transactions cover, subject to customary adjustments, the number of shares of BXP's common stock initially underlying the Notes. Similar to the exchange feature embedded in the Notes, the Capped Call Transactions meet all the conditions for equity classification, and therefore, the related premiums paid are recorded as a reduction to stockholders' equity for BXP and partners' capital for BPLP.

***Fair Value Measurements***

The Company follows the authoritative guidance for fair value measurements when valuing its financial instruments for disclosure purposes. The table below presents for September 30, 2025 and December 31, 2024, the financial instruments that are being valued for disclosure purposes, as well as the Level at which they are categorized as defined in ASC 820 "Fair Value Measurements and Disclosures" ("ASC 820").

---

| | |
|:---|:---|
| **Financial Instrument** | **Level** |
| Unsecured commercial paper | Level 1 |
| Investment in securities | Level 1 |
| Unsecured senior notes (1) | Level 1 |
| Unsecured exchangeable senior notes (1) | Level 1 |
| Related party notes receivable | Level 3 |
| Notes receivable | Level 3 |
| Sales-type lease receivable | Level 3 |
| Mortgage notes payable | Level 3 |
| Unsecured line of credit | Level 3 |
| Unsecured term loans | Level 3 |

---

_______________

&nbsp;&nbsp;&nbsp;&nbsp;(1)If trading volume for the period is low, the valuation could be categorized as Level 2.

Because the Company's valuations of its financial instruments are based on the above Levels and involve the use of estimates, the actual fair values of its financial instruments may differ materially from those estimates. In addition, the Company's estimated fair values for these instruments as of the end of the applicable reporting period are not projections of, nor necessarily indicative of, estimated or actual fair values in future reporting periods.

At September 30, 2025 and December 31, 2024, the Company had $750.0 million and $500.0 million, respectively, outstanding under its unsecured commercial paper program (See Note 6). Due to their short-term maturity and stated interest rates that approximate current market rates, the fair value of outstanding commercial paper borrowings approximates the Company's carrying amount at September 30, 2025 and December 31, 2024.

The Company's non-real estate investments are shown within Prepaid Expenses and Other Assets on the Consolidated Balance Sheets and were approximately $9.4 million and $7.1 million at September 30, 2025 and December 31, 2024, respectively. The non-real estate investments utilize net asset value as the practical expedient.

&nbsp;&nbsp;&nbsp;&nbsp;(1)See Note 14.

During the three months ended September 30, 2025, in conjunction with the Company's strategy to sell non-core assets, the Company evaluated its properties that were under negotiation for sale with third-parties. Based on shorter-than-expected hold periods, the Company reduced the carrying values of the properties that exceeded their fair value and recognized non-cash impairment losses (See Note 3). As a result, during the three and nine months ended September 30, 2025, BXP and BPLP recognized aggregate impairment losses of approximately $68.9 million and $66.0 million, respectively. The Company's estimated fair value was based on Level 3 inputs as defined in ASC 820, including pending offers from third-parties, as pending offers are classified as Level 3 inputs and there were no other unobservable inputs utilized in the consolidated impairment analysis.

<u>Recurring Fair Value</u>

*Derivatives*

In addition to the financial instruments noted above, the Company uses interest rate swap agreements to manage its interest rate risk (See Note 7). The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The following table presents the aggregate fair value of the Company's interest rate swaps as of September 30, 2025 and December 31, 2024 (in thousands):

---

| | | |
|:---|:---|:---|
| **Fair value** | **September 30, 2025** | **December 31, 2024** |
| Interest rate swaps | $(8510) | $5252 |

*Investments*

The Company accounts for investments in equity securities at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. The Company maintains deferred compensation plans that are designed to allow each officer and non-employee director of BXP to defer a portion of the officer's income and the non-employee director's compensation, respectively, on a pre-tax basis and receive a tax-deferred return on the amounts deferred based on the performance of specific investments selected by the plan participant. The Company's obligation under the plans is that of an unsecured promise to pay the deferred compensation to the plan participants in the future. At September 30, 2025 and December 31, 2024, the Company had maintained approximately $43.4 million and $39.4 million, respectively, in separate accounts, which are not restricted as to their use. The Company recognized gains of approximately $2.4 million and $2.2 million on its investments in the accounts associated with the Company's deferred compensation plans during the three months ended September 30, 2025 and September 30, 2024, respectively, and approximately $4.6 million and $4.8 million during the nine months ended September 30, 2025 and September 30, 2024, respectively, primarily due to the observable change in fair value.

***Disposition***

On June 27, 2025, the Company entered into a joint venture with a third-party to redevelop, own and operate 17 Hartwell Avenue in Lexington, Massachusetts. The Company sold the land at 17 Hartwell Avenue to the joint venture for approximately $21.8 million in cash. Upon formation of the joint venture, the Company ceased accounting for the property on a consolidated basis and began accounting for the joint venture on an unconsolidated basis using the equity method of accounting, as it does not have a controlling financial or operating interest in the joint venture (See Note 5). BXP and BPLP recognized gains upon sale of the real estate of approximately $18.4 million and $18.5 million, respectively, during the nine months ended September 30, 2025, within Gains on Sales of Real Estate on the respective Consolidated Statement of Operations, as the fair value of the real estate exceeded its carrying value. 17 Hartwell Avenue contributed approximately $0.3 million of net loss to the Company for the period from January 1, 2025 through June 26, 2025, and contributed approximately $(0.1) million and $0.2 million of net income (loss) to the Company for the three and nine months ended September 30, 2024, respectively. 17 Hartwell Avenue was an approximately 30,000 net rentable square feet office property that was taken out of service during the three months ended June 30, 2024, and was held for future redevelopment. The building has been demolished.

On February 27, 2025, a joint venture in which the Company has a 50% ownership interest entered into a $252.0 million mortgage loan secured by 7750 Wisconsin Avenue in Bethesda, Maryland. The loan is scheduled to mature on March 1, 2035, bears interest at a fixed rate of 5.49% per annum, and requires monthly principal and interest payments. The proceeds from the loan were used to repay the existing $252.0 million construction loan collateralized by the property. The repayment resulted in the joint venture recognizing a loss from early extinguishment of debt of approximately $0.1 million related to unamortized finance costs during the nine months ended September 30, 2025. 7750 Wisconsin Avenue is an office property with approximately 736,000 net rentable square feet.

On March 5, 2025, the Company acquired a 19.46% ownership interest in a joint venture that is developing 290 Coles Street located in Jersey City, New Jersey for a gross purchase price of approximately $20.0 million. Additionally, the Company agreed to fund up to $65.0 million of the required capital through a preferred equity investment. The Company's preferred equity investment will earn a 13.0% IRR and is to be redeemed, in full, upon the earlier of two years after stabilization of the property or March 5, 2030. As of September 30, 2025, the Company has funded approximately $11.9 million of the required capital through the preferred equity investment. On March 5, 2025, the joint venture entered into a $225.0 million construction loan, which will fund construction costs after the funding of all common and preferred equity investments required by the construction loan agreement. The loan bears interest at a variable rate equal to Term SOFR plus 2.50% per annum and is scheduled to mature on March 5, 2029 with an additional one-year extension option, subject to certain conditions. When completed, 290 Coles Street is expected to be a 670-unit residential property with retail space aggregating approximately 560,000 net rentable square feet.

On June 27, 2025, the Company entered into a joint venture to redevelop, own, and operate 17 Hartwell Avenue in Lexington, Massachusetts. The third-party partner contributed approximately $23.0 million of cash, which was used by the joint venture to purchase the land at 17 Hartwell Avenue from the Company for approximately $21.8 million in cash. The Company contributed development costs of approximately $5.6 million for its 20% ownership interest in the joint venture. Additionally, on June 27, 2025, the joint venture entered into a $98.7 million construction loan. The loan bears interest at a fixed rate of 6.75% per annum and is scheduled to mature on July 10, 2030. When completed, 17 Hartwell Avenue is expected to be a 312-unit residential property with garage and retail space (See Note 3).

Subsequently, on September 30, 2025, they entered into a new $465.0 million mortgage loan secured by the two properties. The new loan is scheduled to mature on April 9, 2031, bears interest at a weighted average fixed rate of 5.733% per annum, and requires monthly interest only payments. The proceeds from the new loan and available cash were used to repay the existing $490.0 million construction loans secured by the properties. 100 Causeway Street and Hub on Causeway - Podium are office properties with approximately 634,000 and 383,000 net rentable square feet, respectively, located in Boston, Massachusetts.

*Impairment*

The Company's investments in unconsolidated joint ventures are reviewed for indicators of impairment on a quarterly basis and the Company records impairment charges when events or circumstances indicate that a decline in the fair values below the carrying amounts has occurred and such decline is other-than-temporary. During the three months ended September 30, 2025, the Company evaluated key indicators related to certain investments in unconsolidated joint ventures, including strategic initiatives outlined in the Company's September 8, 2025 Investor Day which include the sale of non-strategic assets, changes in cash flows, declining market conditions and leasing activities, continued actual and projected operating deficits and receipts and considerations of third-party joint venture property appraisals. Such evaluation of key impairment indicators resulted in the Company determining that the decline in value for the joint venture that owns Gateway Commons was other-than-temporary and therefore, the Company recorded an impairment charge of approximately $145.1 million during the three and nine months ended September 30, 2025. The Company determined the fair value of the investment was categorized within Level 3 of the fair value hierarchy as it utilized significant unobservable inputs in its assessment including broker opinions of value and discounted cash flows. The Company's exit capitalization and discount rate ranges used to estimate fair value in its discounted cash flows models were 6.5% -7.5% and 10.0% - 11.0%, respectively.

**6. Debt**

*Unsecured Senior Notes*

On January 15, 2025, BPLP repaid $850.0 million in aggregate principal amount of its 3.200% senior notes due January 15, 2025. The repayment was completed with available cash and the proceeds from BPLP's August 2024 offering of 5.750% unsecured senior notes due 2035. The repayment price was approximately $863.6 million, which was equal to the stated principal plus approximately $13.6 million of accrued and unpaid interest to, but not including, the repayment date.

*Unsecured Exchangeable Senior Notes*

On September 29, 2025, BPLP completed the issuance and sale of $1.0 billion aggregate principal amount of its 2.00% Exchangeable Senior Notes due 2030 in a private placement. The Notes bear interest at a rate of 2.00% per annum, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on April 1, 2026. The Notes will mature on October 1, 2030, unless earlier repurchased, exchanged or redeemed. Net proceeds after the initial offering costs were approximately $975.1 million. Interest expense related to these Notes was approximately $0.1 million for the three and nine months ended September 30, 2025, and includes debt issuance cost amortization of approximately $28,000 for both periods. Including the debt issuance cost amortization, the GAAP interest rate on these Notes is approximately 2.498%. The unamortized debt issuance costs related to these Notes were approximately $24.9 million at September 30, 2025.

Before July 1, 2030, noteholders will have the right to exchange their Notes only upon the occurrence of certain events. From and after July 1, 2030, noteholders may exchange their Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date of the Notes. Exchanges will be settled in cash up to the aggregate principal amount of the Notes to be exchanged and, if applicable, cash, shares of BXP's common stock or a combination thereof, at BPLP's election, in respect of the remainder (if any) of BPLP's exchange obligations in excess of the aggregate principal amount of the Notes being exchanged. The initial exchange rate is 10.8180 shares of BXP's common stock per $1,000 principal amount of Notes, which represents an initial exchange price of approximately $92.44 per share of BXP's common stock. The initial exchange price represents a premium of approximately 22.5% over the last reported sale price of $75.46 per share of BXP's common stock on September 24, 2025. The exchange rate and exchange price of the Notes will be subject to adjustment upon the occurrence of certain events.

The Notes will be redeemable, in whole or in part (subject to certain limitations), for cash at BPLP's option at any time, and from time to time, on or after October 6, 2028 and on or before the 41st scheduled trading day immediately before the maturity date of the notes, but only if the last reported sale price per share of BXP's common stock exceeds 130% of the exchange price of the Notes for a specified period of time and certain liquidity conditions are satisfied. BPLP may also redeem the Notes, in whole or in part (subject to certain limitations), for cash at any time, and from time to time, if BXP's Board of Directors (or a committee thereof) determines such redemption is necessary to preserve BXP's status as a real estate investment trust. In either case, the redemption price will be equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

In conjunction with the issuance of the Notes, the Company entered into Capped Call Transactions with certain financial institutions. The Capped Call Transactions cover, subject to customary adjustments, the number of shares of BXP's common stock initially underlying the Notes. The Capped Call Transactions are expected generally to reduce the potential dilution to BXP's common stock upon any exchange of Notes and/or offset any cash payments BPLP is required to make in excess of the principal amount of exchanged Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the Capped Call Transactions is initially $105.64 per share, and is subject to certain adjustments under the terms of the Capped Call Transactions. The Capped Call Transactions will expire upon the maturity of the Notes, if not earlier exercised or terminated. A portion of the proceeds from the Notes were used to pay the premiums of the Capped Call Transactions of approximately $35.0 million, which was recorded as a reduction to stockholders' equity for BXP and partners' capital for BPLP (See Note 2).

*Unsecured Credit Facility and Unsecured Term Loans*

On March 28, 2025, BPLP amended and restated its revolving credit agreement (as amended and restated, the "2025 Credit Facility"). The 2025 Credit Facility provides for aggregate borrowings of up to $2.950 billion through an unsecured revolving credit facility and an unsecured term loan facility, subject to customary conditions. Among other things, the amendment and restatement (1) increased the total commitment of the revolving line of credit (the "Revolving Facility") from $2.0 billion to $2.250 billion, (2) extended the maturity date of the Revolving Facility from June 15, 2026 to March 29, 2030, and (3) added a $700.0 million unsecured term loan facility (the "Term Loan Facility") with an initial maturity date of March 30, 2029, with two, six-month extension options, each subject to customary conditions. In addition, BPLP may increase the total commitment under the 2025 Credit Facility to a maximum commitment amount of up to $3.5 billion through increase(s) in the Revolving Facility and/or by incurring one or more term loans, in each case, subject to syndication of the increase(s) and other customary conditions. In connection with the amendment and restatement, the Company recognized a loss from early extinguishment of debt of approximately $0.3 million related to unamortized origination costs during the nine months ended September 30, 2025.

At BPLP's option, loans under the 2025 Credit Facility that are advanced in U.S. dollars will bear interest at a rate per annum equal to Term SOFR, Daily Simple SOFR or a Base Rate (each as defined in the Tenth Amended and Restated Credit Agreement, which governs the 2025 Credit Facility (the "Credit Agreement")), in each case, plus a margin based on BPLP's credit rating ranging from (i) for Term SOFR and Daily Simple SOFR loans, (a) under the Revolving Facility, 70.0 to 140.0 basis points, or (b) under the Term Loan Facility, 75.0 to 160.0 basis points (plus a SOFR conversion adjustment of 10 basis points), and (ii) for Base Rate loans, (a) under the Revolving Facility, 0 to 40.0 basis points, or (b) under the Term Loan Facility, 0 to 60.0 basis points. At BPLP's option, loans under the Revolving Facility can also be denominated in Euros, Sterling or Canadian Dollars and such loans will bear interest at a rate per annum equal to (1) in the case of loans denominated in Euro, EURIBOR, (2) in the case of loans denominated in Canadian Dollars, Term CORRA (as adjusted), and (3) in the case of loans denominated in Sterling, SONIA (as adjusted), plus, in each case, a margin based on BPLP's credit rating as described above for loans under the Revolving Facility. On April 22, 2025, BPLP amended the 2025 Credit Facility to remove the SOFR conversion adjustment of 10 basis points (as described in clause (i)(b) above), which is no longer applicable to the Term Loan Facility. Other than the foregoing, the material terms of the 2025 Credit Facility remained unchanged.

Pursuant to the 2025 Credit Facility, BPLP is obligated to pay (1) in quarterly installments a facility fee on the total commitment under the Revolving Facility at a rate per annum ranging from 0.10% to 0.30% based on BPLP's credit rating and (2) an annual fee on the undrawn amount of each letter of credit ranging from 0.70% to 1.40% based on BPLP's credit rating.

Based on BPLP's September 30, 2025 credit rating, (1) for SOFR-based loans under the Revolving Facility, the per annum interest rate margin is 0.85%, (2) for SOFR-based loans under the Term Loan Facility, the per annum interest rate margin is 0.95%, (3) for Base Rate-based loans under both the Revolving Facility and Term Loan Facility, the margin is zero basis points and (4) the facility fee for commitments under the Revolving Facility is 0.20% per annum.

The 2025 Credit Facility contains customary representations and warranties, affirmative and negative covenants, and events of default provisions, including the failure to pay indebtedness, breaches of covenants and bankruptcy and other insolvency events, which could result in the acceleration of the obligation to repay all outstanding amounts and the cancellation of all commitments outstanding under the Credit Agreement. Among other covenants, the 2025 Credit Facility requires that BPLP maintain: (1) a leverage ratio not to exceed 60%, however, the leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within one

At September 30, 2025, BPLP was in compliance with each of these financial restrictions and requirements.

At closing on March 28, 2025, BPLP drew the full $700.0 million of the Term Loan Facility under the 2025 Credit Facility, the proceeds of which were used to fully repay the remaining $700.0 million of borrowings outstanding under it's $1.2 billion unsecured term loan facility (the "2023 Unsecured Term Loan"). The 2023 Unsecured Term Loan was scheduled to mature on May 16, 2025. There was no prepayment penalty associated with the repayment of the 2023 Unsecured Term Loan.

At September 30, 2025, BPLP did not have any outstanding balance under the Revolving Facility and had $700.0 million outstanding under the Term Loan Facility. The 2025 Credit Facility is used as a backstop for BPLP's $750.0 million unsecured commercial paper program (the "Commercial Paper Program") (See "*Unsecured Commercial Paper"* below). As such, BPLP intends to maintain, at a minimum, availability under the 2025 Credit Facility in an amount equal to the amount of unsecured commercial paper notes outstanding.

On September 27, 2024, BPLP entered into a credit agreement that provides for a $100.0 million unsecured term loan facility (the "2024 Unsecured Term Loan"). Upon entry into the credit agreement, BPLP exercised its option to draw $100.0 million under the 2024 Unsecured Term Loan. The 2024 Unsecured Term Loan had an initial maturity date of September 26, 2025 with three, one-year extension options, subject to customary conditions. On September 26, 2025, BPLP exercised its option to extend the maturity date of the 2024 Unsecured Term Loan to September 26, 2026. All other terms of the 2024 Unsecured Term Loan remain unchanged.

*Unsecured Commercial Paper*

On March 28, 2025, BPLP increased the amount by which it may issue unsecured commercial paper notes under the Commercial Paper Program from $500.0 million to $750.0 million. Other than the increase in the program's maximum capacity, all other terms of the Commercial Paper Program remain unchanged. Under the terms of the program, BPLP may issue, from time to time, unsecured commercial paper notes up to a maximum aggregate amount outstanding at any one time of $750.0 million with varying maturities of up to one year. Amounts available under the Commercial Paper Program may be borrowed, repaid, and re-borrowed from time to time. The notes are sold in private placements and rank pari passu with all of BPLP's other unsecured senior indebtedness, including its outstanding senior notes. The Commercial Paper Program is backstopped by available capacity under the 2025 Credit Facility. At September 30, 2025, BPLP had an aggregate of $750.0 million of unsecured commercial paper notes outstanding that bore interest at a weighted-average rate of approximately 4.51% per annum and had a weighted-average maturity of 43 days from the issuance date.

**7. Derivative Instruments and Hedging Activities**

BPLP's agreements with derivative counterparties contain provisions whereby if BPLP defaults on the underlying indebtedness, including defaults where repayment of the indebtedness has not been accelerated by the lender, then BPLP could also be declared in default of the swap derivative obligation. As of September 30, 2025, the Company had not posted any collateral related to the agreements.

*Effective Hedge Instruments*

On April 8, 2025, BPLP entered into an interest rate swap contract with a notional amount of $300.0 million to replace $300.0 million of interest rate swap contracts that expired on April 1, 2025 thus continuing to reduce its exposure to the variability in future cash flows attributable to changes in the interest rates associated with its $100.0 million 2024 Unsecured Term Loan and the $200.0 million mortgage secured by the Company's Santa Monica Business Park properties, located in Santa Monica, California. The interest rate swap was entered into to fix Daily Simple SOFR, the reference rate for the 2024 Unsecured Term Loan and mortgage, at a fixed interest rate of 3.6775% per annum for the period commencing on April 7, 2025, the effective date, and ending on April 6, 2026. For the three months ended September 30, 2025 and the period from April 7, 2025 through September 30, 2025, the Company recognized approximately $(0.5) million and $(1.0) million, respectively, of interest expense related to this interest rate swap contract.

BPLP assesses the effectiveness of its derivatives both at inception and on an ongoing basis. If the hedges are deemed to be effective, the fair value is recorded in "Accumulated other comprehensive loss" in the Company's Consolidated Balance Sheets and is subsequently reclassified into "Interest expense" in the Company's Consolidated Statements of Operations in the period that the hedged forecasted transactions affect earnings. BPLP's derivative financial instruments are cash flow hedges that are designated as effective hedges, and they are carried at their estimated fair value on a recurring basis (See Note 2). The Company did not have any undesignated hedges during the three and nine months ended September 30, 2025.

BPLP's derivative contracts consisted of the following at September 30, 2025 (dollars in thousands):

&nbsp;&nbsp;&nbsp;&nbsp;(2)Includes amounts from previous interest rate programs.

BPLP has formally documented all of its relationships between hedge instruments and hedging items, as well as its risk-management objectives and strategy for undertaking various hedge transactions. While management believes its judgments are reasonable, a change in a derivative's effectiveness as a hedge could materially affect expenses, net income (loss) and equity.

**8. Commitments and Contingencies** 

*General*

In the normal course of business, the Company guarantees its performance of services or indemnifies third parties against its negligence. In addition, in the normal course of business, the Company guarantees to certain tenants the obligations of the Company's subsidiaries to complete construction of the building, to pay tenant improvement allowances and brokerage commissions in connection with their leases and limited costs arising from delays in delivery of their premises.

The Company had letter of credit and performance obligations related to lender and development requirements that totaled approximately $23.5 million at September 30, 2025.

Certain of the Company's joint venture agreements include provisions whereby, at certain specified times, each partner has the right to initiate a purchase or sale of its interest in the joint venture. From time to time, under certain of the Company's joint venture agreements, if certain return thresholds are achieved, one or more partners could be entitled to an additional promoted interest or payments.

<u>[**Table of Contents**](#ifba0473e2fbc413ba4e5193d63dc3952_10)</u>[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)

From time to time, the Company (or ventures in which the Company has an ownership interest) has agreed, and may in the future agree, to (1) guarantee portions of the principal, interest and other amounts in connection with their borrowings, (2) provide customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) in connection with their borrowings and (3) provide guarantees to lenders, tenants and other third parties for the completion of development projects. The Company has agreements with its third-party joint venture partners whereby the partners agree to reimburse the joint venture for their share of any payments made under the guarantee. In some cases, the Company earns a fee from the applicable joint venture for providing the guarantee.

In connection with the sale of Metropolitan Square, an approximately 657,000 square foot office building in Washington, DC in which the Company had a 20% equity interest, the Company agreed to become a co-lender of up to $20.0 million under a mezzanine loan. The mezzanine loan has a maximum principal amount of $100.0 million, and it is subordinate only to an existing senior loan. The mezzanine loan may be drawn upon for future lease-up, operating and other costs on an as-needed basis, and amounts borrowed will bear interest at a per annum rate of 12%, compounded monthly. As of September 30, 2025, the Company has funded approximately $9.0 million under the mezzanine loan.

*Legal Matters* 

The Company is subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. Management believes that the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or liquidity of the Company.

In addition, the Company is subject to the following legal proceedings:

In connection with the acquisition of an office property in New York City in 2010, the Company entered into an agreement with the seller pursuant to which the seller could earn various fees (i.e., Fixed, Additional and Final Fees) based on the future leasing performance of the property. The Company initially accrued approximately $1.5 million as an estimate of the fees it would owe the seller. In 2020, the seller filed suit against the Company in the Supreme Court of the State of New York, County of New York, claiming that consideration significantly in excess of the initial reserve amount is owed under the agreement. The disagreement between the Company and the seller involves material issues of contract interpretation and, more importantly, the method of calculating fees, including various inputs (both facts and assumptions) that drive the calculations.

On January 25, 2024, the New York Supreme Court granted in part the seller's motion for summary judgment finding that the Company owes the seller an "Additional Fee" and a "Final Fee" under the terms of the parties' purchase agreement. The court issued a follow-on order on February 8, 2024, confirming its earlier order that the seller is entitled to the fees described in the parties' agreement. Other than the "Fixed Fee," which the Company agreed to pay and for which it had established a reserve of approximately $2.2 million (including interest), the amount of the fees (if any) that are due to the seller has not been determined. On December 9, 2024, the court issued a judgment awarding the seller the Fixed Fee (including interest) of approximately $2.7 million and the Company paid this fee following the judgment. For the Additional Fee and Final Fee, the seller submitted a request for the appointment of a Special Referee on January 7, 2025. Separately, the Company filed a notice of appeal on January 15, 2025 to preserve the Company's ability to appeal the grant of summary judgment on the question of whether the Company is liable for payment of the Additional Fee and Final Fee.

The issue of an award of damages for the Additional Fee and the Final Fee remains outstanding with the court pending a determination by the Special Referee, which the court appointed on February 18, 2025. The Company disputes the seller's calculations and intends to continue defending itself vigorously. However, there can be no assurance that the Company will prevail in the lawsuit. If the court ultimately agrees with the seller's calculations, then amounts due to the seller could theoretically be as high as the additional $31 million claimed in the seller's complaint, plus interest. Although the Company disputes those calculations, there can be no assurance that the Company's ultimate liability will not be material.

On April 26, 2024, Brammer Bio MA, LLC ("Brammer"), a subsidiary of Thermo Fisher Scientific Inc. and an abutter to the Company's 290 Binney Street development project located in Cambridge, Massachusetts, filed a complaint in Superior Court in Suffolk County, Massachusetts against the Company relating to certain ongoing construction activities.

------

<u>[**Table of Contents**](#ifba0473e2fbc413ba4e5193d63dc3952_10)</u>[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)

In the first quarter of 2023, the Company commenced development of 290 Binney Street, an approximately 573,000 net rentable square foot laboratory/life sciences property that is 100% pre-leased to AstraZeneca Pharmaceuticals ("AstraZeneca"). The Company has a 55% interest in the joint venture that owns 290 Binney Street. Brammer subleases the premises at 250 Binney Street, the Company's approximately 67,000 net rentable square foot life sciences property that is adjacent to 290 Binney Street.

Brammer alleged that, as a result of the Company's construction of 290 Binney Street, it is threatened with irreparable harm due to intrusion onto the 250 Binney Street premises and the loss of its property rights. Brammer also alleged that the 290 Binney Street development project has caused and is causing major disruption to its manufacturing operations, and that it has suffered and will continue to suffer damages in the form of losses to its clients and customers. Brammer brought the action for quiet title, breach of contract, trespass and nuisance, and it is seeking declaratory and injunctive relief and specific performance purportedly to protect its property interests in the premises located at 250 Binney Street.

On May 16, 2024, Brammer's motion for a preliminary injunction was denied by the trial court. Brammer subsequently appealed that decision, electing pursuant to Massachusetts civil procedure rules to petition for appeals to both a single justice of the Massachusetts Appeals Court and to a full appellate panel. On July 16, 2024, the single justice assigned to the appeal issued an order declining to rule on the substance of the appeal petition, deferring instead to the full appellate panel. On August 12, 2025, the clerk of the Massachusetts Appeals Court completed the procedural steps that were necessary in order for Brammer's appeal to be heard before the full appellate panel. The parties are now proceeding through the briefing process, with a hearing likely to take place sometime in the first quarter of 2026. The remainder of the case continues to proceed in the trial court on the standard litigation timeline.

The Company believes it has meritorious defenses against Brammer's claims and intends to defend against them vigorously. However, there can be no assurance the Company will prevail in the litigation. If the Company is enjoined from further construction activities, it could suffer delays in construction that could result in its failure to deliver a completed building on the schedule contemplated by the Company's lease with AstraZeneca or at all, and this could result in owing financial penalties to AstraZeneca and other third parties. Although the Company is unable to estimate a range of loss for all related matters for which losses are reasonably possible, if the court grants injunctive relief or awards monetary damages to Brammer, it could have a material adverse effect on the Company's results of operations and financial condition.

The Company is a named defendant in an alleged collective and class action wage and hour lawsuit filed on behalf of certain individuals who provided off-duty, uniformed security services at the Company's buildings in New York City pursuant to the New York Police Department's Paid Detail Program. In addition to the Company, the plaintiffs also named as defendants more than ninety (90) other entities and institutions in the city. The plaintiffs filed the lawsuit in the United States District Court for the Southern District of New York on January 24, 2025, and brought the claims under the Fair Labor Standards Act, the New York Labor Law and the Freelance Isn't Free Act. The plaintiffs subsequently amended the complaint on February 7, 2025 and on February 24, 2025. The plaintiffs have advised the defendants and the court that they intend to file a motion for leave to file a Third Amended Complaint. The deadline for plaintiffs to file that motion is December 15, 2025. Each of the complaints filed to date alleges that the plaintiffs were not paid certain wages owed to them or were not paid in a timely manner and that the plaintiffs did not receive certain wage payment notices and wage statements required by law. The Company has not yet filed a responsive pleading as no responsive pleading is yet due, and discovery has not yet commenced. As a result, the Company is unable to estimate a range of loss for which losses are reasonably possible. Although the Company believes it has meritorious defenses to the claims and intends to defend against them vigorously, there can be no assurance that the Company will prevail in the lawsuit.

**9. Noncontrolling Interests** 

Noncontrolling interests relate to the interests in BPLP not owned by BXP and interests in consolidated property partnerships not wholly-owned by the Company. As of September 30, 2025, the noncontrolling interests in BPLP consisted of the following:

__________

&nbsp;&nbsp;&nbsp;&nbsp;(1)Includes 655,534 LTIP Units earned by employees under the Company's multi-year long-term incentive awards granted between 2012 and 2022 (i.e., 2012 OPP and 2013 - 2022 MYLTIP awards).

***Noncontrolling Interest—Common Units***

During the nine months ended September 30, 2025, 143,823 OP Units were presented by the holders for redemption (including an aggregate of 37,944 OP Units issued upon conversion of LTIP Units, 2012 OPP Units and MYLTIP Units) and were redeemed by BXP in exchange for an equal number of shares of Common Stock.

At September 30, 2025, BPLP had outstanding the 2023 - 2025 MYLTIP Units. Prior to the end of the respective three-year performance period for each plan, holders of MYLTIP Units are entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the three-year performance period for each plan has ended, (1) the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit and (2) with respect to the 2023 - 2025 MYLTIP Units, the Company will make a "catch-up" cash payment on the MYLTIP Units that are ultimately earned in an amount equal to the regular and special dividends, if any, declared during the performance period on a number of shares of Common Stock equal to the number of 2023 - 2025 MYLTIP Units that are earned, less the distributions actually paid during the performance period on all of the awarded 2023 - 2025 MYLTIP Units.

On January 31, 2025, the three-year measurement period for the Company's 2022 MYLTIP awards ended and, based on BXP's absolute and relative TSR performance, the final payout was determined to be 59% of target, or an aggregate of approximately $5.4 million (after giving effect to employee separations). As a result, an aggregate of 177,919 2022 MYLTIP Units that had been previously granted were automatically forfeited.

The following table presents BPLP's distributions on the OP Units and LTIP Units and MYLTIP Units paid or declared in 2025 and during the nine months ended September 30, 2024:

A holder of an OP Unit may present the OP Unit to BPLP for redemption at any time (subject to covenants agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, BPLP must redeem the OP Unit for cash equal to the then value of a share of Common Stock of BXP. BXP may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing one share of Common Stock. Based on the last reported price of a share of Common Stock on the New York Stock Exchange of $74.34 per share on September 30, 2025, the value of the OP Units (other than OP Units owned by BXP), and LTIP Units (including the 2012 OPP Units and 2013 - 2022 MYLTIP Units), assuming in each case that all conditions had been met for the conversion thereof, had all of such units been redeemed at September 30, 2025 was approximately $1.4 billion.

***Noncontrolling Interests—Property Partnerships***

The noncontrolling interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaling approximately $2.0 billion and $1.9 billion at September 30, 2025 and December 31, 2024, respectively, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.

On August 27, 2025, the Company acquired its partner's 45% ownership interest in the consolidated entity that is developing the 343 Madison Avenue project located in New York City, New York for approximately $43.5 million of cash. The acquisition price is equal to the partner's aggregate unreturned capital contributions to the joint venture and as a result there was no gain on sale recognized in stockholders' equity for BXP or partners' capital for BPLP other than transaction costs. Prior to the acquisition, the Company had a 55% ownership interest in the joint venture (See Note 3).

**10. Stockholders' Equity / Partners' Capital** 

As of September 30, 2025, BXP had 158,400,414 shares of Common Stock outstanding.

As of September 30, 2025, BXP owned 1,767,998 general partnership units and 156,632,416 limited partnership units in BPLP.

On May 17, 2023, BXP renewed its "at the market" ("ATM") stock offering program through which it may sell from time to time up to an aggregate of $600.0 million of its Common Stock through sales agents over a three-year period. Under the ATM stock offering program, BXP may also engage in forward sale transactions with affiliates of certain sales agents for the sale of its Common Stock on a forward basis. This program replaced BXP's prior $600.0 million ATM stock offering program that was scheduled to expire on May 22, 2023. BXP intends to use the net proceeds from any offering for general business purposes, which may include investment opportunities and debt reduction. No shares of Common Stock have been issued under this ATM stock offering program.

During the nine months ended September 30, 2025, BXP issued 143,823 shares of Common Stock in connection with the redemption of an equal number of redeemable OP Units from limited partners.

The following table presents BXP's dividends per share and BPLP's distributions per OP Unit and LTIP Unit paid or declared in 2025 and during the nine months ended September 30, 2024:

**11. Segment Information** 

Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the Chief Operating Decision Makers ("CODM"). The CODM decides how resources should be allocated and assesses performance on a recurring basis, at least quarterly. The Company's CODMs are its Chief Executive Officer and President. The CODMs review operating performance and financial reports by geographic area and property type. In addition, given the size of the Company's joint venture portfolio, the CODMs utilize the Company's share of net operating income ("NOI"), which includes the Company's share of NOI from consolidated and unconsolidated joint ventures, as its profit or loss measure in assessing each segment's performance and deciding how to allocate resources.

<u>[**Table of Contents**](#ifba0473e2fbc413ba4e5193d63dc3952_10)</u>[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)

The Company's share of NOI is used by the CODMs to evaluate the profitability and performance of each geographic area on a consistent and comparable basis, supporting decisions on capital resource allocation, including in connection with development, redevelopment, acquisition and disposition activities in each segment. Additionally, the Company believes its share of NOI is useful as a profit or loss measure and believes it provides useful information regarding its results of operations and financial condition because, when compared across periods, it reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership.

Asset information by segment is not reported because the Company and the CODMs are not provided with the segment asset information and therefore do not use this measure to assess performance or allocate resources. Asset values for the Company's properties are reported in the Consolidated Balance Sheets at historical cost, which may not reflect current market values. Therefore, depreciation and amortization expense is not allocated among segments. The following are not included in the Company's share of NOI as they are not necessarily linked to the operating performance of a real estate asset and are often incurred at the corporate level as opposed to the property level: development and management services revenue, direct reimbursements of payroll and related costs from management services contracts, income (loss) from unconsolidated joint ventures, gains on sales of real estate, interest and other income (loss), gains from investments in securities, unrealized gain (loss) on non-real estate investments, corporate general and administrative expense, payroll and related costs from management services contracts, transaction costs, depreciation and amortization expense, loss on sales-type lease, impairment losses, loss from early extinguishment of debt, interest expense and net (income) loss attributable to noncontrolling interests. The Company's share of NOI presented may not be comparable to what is reported by other REITs or real estate companies that define NOI differently.

The Company's segments by geographic area are Boston, Los Angeles, New York, San Francisco, Seattle and Washington, DC. The Company also presents information for each segment by property type, including Office (which includes office, life sciences and retail), Residential and Hotel. The Company shows the different property types as the revenue from each type is derived from non-comparable lease structures.

**12. Earnings Per Share / Common Unit** 

***BXP***

The following table provides a reconciliation of both the net income (loss) attributable to BXP, Inc. and the number of common shares used in the computation of basic earnings per share ("EPS"), which is calculated by dividing net income (loss) attributable to BXP, Inc. by the weighted-average number of common shares outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of BXP and BPLP's LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic EPS of BXP using the two-class method. Participating securities are included in the computation of diluted EPS of BXP using the if-converted method if the impact is dilutive. Because the 2012 OPP Units and 2013 - 2022 MYLTIP Units required, and the 2023 - 2025 MYLTIP Units require, BXP to outperform certain performance thresholds, unless such thresholds have been met by the end of the applicable reporting period, BXP excludes such units from the diluted EPS calculation. Other potentially dilutive common shares, including restricted stock and other securities of BPLP that are exchangeable for BXP's Common Stock (See Note 2), and the related impact on earnings, are considered when calculating diluted EPS.

***BPLP***

The following table provides a reconciliation of both the net income (loss) attributable to Boston Properties Limited Partnership and the number of common units used in the computation of basic earnings per common unit, which is calculated by dividing net income (loss) attributable to Boston Properties Limited Partnership by the weighted-average number of common units outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of BXP and BPLP's LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities.

Other potentially dilutive common units (See Note 2) and the related impact on earnings are considered when calculating diluted earnings per common unit. Included in the number of units (the denominator) below are approximately 17,556,000 and 17,721,000 redeemable common units for the three months ended September 30, 2025 and 2024, respectively, and 17,555,000 and 18,119,000 redeemable common units for the nine months ended September 30, 2025 and 2024, respectively.

**13. Stock Option and Incentive Plan** 

On January 22, 2025, BXP's Compensation Committee approved the 2025 Multi-Year Long-Term Incentive Program (the "2025 MYLTIP") awards under the BXP, Inc. 2021 Stock Incentive Plan (the "2021 Plan") to certain executive officers of BXP. The 2025 MYLTIP awards consist of three components. Two of the components are each weighted 40% and utilize BXP's TSR and BXP's diluted Funds from Operations ("FFO") per share growth, respectively, over a three-year measurement period as the performance metrics and the third component, weighted 20%, utilizes an average leverage ratio as the performance metric. Earned awards will range from zero to a maximum of 354,940 LTIP Units depending on BXP's performance under the three components, with a target of approximately 177,470 LTIP Units. Under ASC 718 "Compensation – Stock Compensation," the 2025 MYLTIP awards have an aggregate value of approximately $12.7 million.

On January 31, 2025, the three-year measurement period for the Company's 2022 MYLTIP awards ended and, based on BXP's absolute and relative TSR performance, the final payout was determined to be 59% of target, or an aggregate of approximately $5.4 million (after giving effect to employee separations). As a result, an aggregate of 177,919 2022 MYLTIP Units that had been previously granted were automatically forfeited.

During the nine months ended September 30, 2025, BXP issued 55,571 shares of restricted common stock and BPLP issued 406,646 LTIP Units and 354,940 2025 MYLTIP Units to employees, the life sciences advisory board members and non-employee directors under the 2021 Plan. The grantees paid $0.25 per LTIP Unit and 2025 MYLTIP Unit. When issued, LTIP Units are not economically equivalent in value to a share of Common Stock, but over time can increase in value to one-for-one parity with Common Stock if there is sufficient appreciation in the value of the Company's assets. The aggregate value of the LTIP Units is included in noncontrolling interests in the Consolidated Balance Sheets of BXP and BPLP. A substantial majority of the grants of restricted common stock and LTIP Units to employees vest in four equal annual installments. Restricted common stock is measured at fair value on the date of grant based on the number of shares granted and the closing price of BXP's Common Stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. The shares of restricted common stock granted during the nine months ended September 30, 2025 were valued at approximately $4.0 million. The LTIP Units granted were valued at

approximately $27.0 million using a Monte Carlo simulation method model. Because the 2012 OPP Units and 2013 - 2025 MYLTIP Units are subject to both a service condition and a market condition, the Company recognizes the related compensation expense under the graded vesting attribution method. Under the graded vesting attribution method, each portion of the award that vests at a different date is accounted for as a separate award and recognized over the period appropriate to that portion so that the compensation cost for each portion should be recognized in full by the time that portion vests. The Company recognizes forfeitures as they occur on its awards of stock-based compensation. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Dividends in Excess of Earnings in BXP, Inc.'s Consolidated Balance Sheets and Partners' Capital in Boston Properties Limited Partnership's Consolidated Balance Sheets. Aggregate stock-based compensation expense associated with restricted stock, LTIP Units and MYLTIP Units was approximately $4.4 million and $4.0 million for the three months ended September 30, 2025 and 2024, respectively, and $39.0 million and $38.5 million for the nine months ended September 30, 2025 and 2024, respectively. At September 30, 2025, there was (1) an aggregate of approximately $24.3 million of unrecognized compensation expense related to unvested restricted stock and LTIP Units and (2) an aggregate of approximately $0.7 million of unrecognized compensation expense related to unvested 2023 - 2025 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.3 years.

**14. Subsequent Events** 

On October 8, 2025, a joint venture in which the Company has a 50% ownership interest repaid the construction loan collateralized by its Dock 72 property. At the time of the repayment, the loan had an outstanding principal balance of approximately $198.4 million, bore interest at a variable rate equal to SOFR plus 2.50% per annum and was scheduled to mature on December 18, 2025. The repayment was completed with available cash and proceeds from capital contributions. Dock 72 is an office building with approximately 669,000 net rentable square feet located in Brooklyn, New York.

On October 17, 2025, the Company completed the sale of Plaza at Almaden, a land parcel located in San Jose, California for a gross sale price of approximately $13.5 million. Net proceeds totaled approximately $12.7 million (See Note 3).

On October 17, 2025, a joint venture in which the Company has a 25% ownership interest refinanced the mortgage loan secured by its 3 Hudson Boulevard property located in New York City, New York. The new loan consists of a (1) senior loan provided by a third-party lender with a principal amount of $108.0 million that bears interest at a variable rate equal to Term SOFR plus 5.25% per annum and (2) mezzanine loan provided by the Company with a maximum commitment of $50.0 million that bears interest at a variable rate equal to Term SOFR plus 7.25% per annum. As of the closing, the Company had funded approximately $17.6 million of the mezzanine loan. The senior loan and mezzanine loan are interest-only, mature on November 9, 2027 and have a one-year extension option, subject to certain conditions. The previous mortgage loan (1) had an outstanding principal balance of $80.0 million and approximately $51.4 million of unpaid accrued interest (including default interest), (2) matured on August 7, 2024 and was in maturity default and (3) bore interest at a variable rate equal to Term SOFR plus 3.61% per annum plus a default rate equal to an additional 4.0% per annum. The Company provided the previous mortgage financing to the joint venture and elected to waive the unpaid accrued default interest of approximately $5.8 million. The Company determined it was not reasonably probable that it would collect the default interest and therefore had been reserving for it within Interest and Other Income (Loss) on its Consolidated Balance Sheets. The previous loan has been reflected as a Related Party Note Receivable on the Company's Consolidated Balance Sheets.

**ITEM 2—Management's Discussion and Analysis of Financial Condition and Results of Operations.**

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report.

This Quarterly Report on Form 10-Q, including the documents incorporated by reference herein, contain forward-looking statements within the meaning of the federal securities laws, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995, and we are including this statement for purposes of complying with those safe harbor provisions, in each case, to the extent applicable. The forward-looking statements are contained principally, but not only, under the captions "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations." We caution investors that forward-looking statements are based on current beliefs, expectations of future events and assumptions made by, and information currently available to, our management. When used, the words "anticipate," "believe," "budget," "could," "estimate," "expect," "intend," "may," "might," "plan," "project," "should," "will," and similar expressions that do not relate solely to historical matters are intended to identify forward-looking statements. These statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance or occurrences, which may be affected by known and unknown risks, trends, uncertainties and factors that are, in some cases, beyond our control. If one or more of these known or unknown risks or uncertainties materialize, or if underlying assumptions prove incorrect, actual results may differ materially from those expressed or implied by the forward-looking statements. We caution you that, while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance or occurrences and are impacted by actual events when they occur after we make such statements. Accordingly, investors should use caution in relying on forward-looking statements, which are based on results, trends and assumptions at the time they are made, to anticipate future results or trends.

The most significant factors that may cause actual results to differ materially from those expressed or implied by the forward-looking statements include the following risks and uncertainties, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• volatile or adverse economic, capital markets and political conditions, including continued inflation, elevated interest rates, supply chain disruptions, policy changes related to tariffs and prolonged government shutdowns or disruptions, which may directly or indirectly impact us, our current clients and our prospective clients, including their demand for office space, and the costs and availability of construction materials and the economic returns on our construction and development activities;

**Overview**

BXP is one of the largest publicly traded office real estate investment trusts (REITs) (based on total market capitalization as of September 30, 2025) in the United States that develops, owns, and manages primarily premier workplaces. Our properties are concentrated in six dynamic gateway markets in the U.S. - Boston, Los Angeles, New York, San Francisco, Seattle and Washington, DC.

We generate revenue and cash primarily by leasing premier workplaces to our clients. We consider premier workplaces to be well-located buildings that are modern structures or have been modernized to compete with newer buildings, are professionally managed and maintained, and offer a number and type of amenities that are in high demand by clients that are focused on the importance of the physical work environment in recruiting and retaining the best and brightest employees. As such, these properties attract creditworthy clients and command upper-tier rental rates in their markets. We do not consider the expression "premier workplaces" a classification of our properties in accordance with any standard listing criteria in the real estate industry. We therefore caution investors that our use and definition of "premier workplaces" may be different than the use and definition of similar expressions and traditional classifications that may be used by other companies.

When making leasing decisions, we consider, among other things, the creditworthiness of the client and the industry in which it conducts business, the length of the lease, the rental rate to be paid at inception and throughout the lease term, the amount of any security deposit or letter of credit posted by the client, the costs of tenant improvement allowances, free rent periods and other landlord concessions, anticipated operating expenses and real estate taxes, the date by which we expect to begin revenue recognition for the lease under generally accepted accounting principles ("GAAP"), current and anticipated vacancy in our properties and the market overall (including

sublease space), current and expected future demand for the space, the impact of other clients' expansion rights and general economic factors.

We believe our key competitive advantages are our commitments to the office asset class and to our clients as many competitors have divested from the sector, a strong balance sheet with access to capital in the secured and unsecured debt markets and the private and public equity markets, and one of the highest quality portfolios of premier workplaces in the U.S. assembled over several decades of intentional development, acquisitions and dispositions. Clients and their advisors are increasingly focused on building owners with these attributes, a factor that distinguishes BXP among its competitors.

Our core strategy has always been to develop, acquire and manage premier workplaces in gateway markets with high barriers-to-entry and attractive demand drivers and to focus on executing long-term leases with financially strong clients that are diverse across market sectors. We believe this strategy provides a competitive advantage as our clients are interested in leasing space in vibrant, amenitized and accessible premier workplaces. This interest has accelerated the flight to quality in the office market. Over the past several years, BXP's experience and performance has diverged from the larger market and media sentiment, as premier workplaces have outperformed the broader office market consistently and substantially in both rental rates achieved and occupancy. We believe this divergence validates our strategy and differentiates BXP from other office companies.

Premier workplaces in our five traditional central business district ("CBD") markets (Boston, New York, San Francisco, Seattle and Washington, DC) have consistently outperformed the broader office market in those CBDs on several key metrics, including occupancy, net absorption levels, rental rates and landlord concessions. This outperformance is evident in BXP's portfolio where we derive approximately 89% of our share of annualized rental obligations from predominantly premier workplaces located in CBDs. We define annualized rental obligations as the monthly contractual base rent (excluding percentage rent and rent abatements) and budgeted reimbursements from clients under existing leases as of September 30, 2025, multiplied by twelve. Our share of annualized rental obligations is calculated as the consolidated amount, plus our share of the amount from our unconsolidated joint ventures (calculated based on our economic percentage ownership interest), less our partners' share of the amount from our consolidated joint ventures (calculated based on the partners' economic percentage ownership interest). As of September 30, 2025, our CBD assets are 89.3% occupied and 92.0% leased (including vacant space for which we have signed leases that have not yet commenced in accordance with GAAP).

As of September 30, 2025, the weighted-average remaining lease term for (1) our in-place leases, based on square feet, including those signed by our unconsolidated joint ventures but excluding residential units, was approximately 7.8 years, and (2) our 20 largest clients, based on square feet, was approximately 10.0 years. Through year-end 2027, we have historically low exposure to contractual lease expirations with approximately 8.7% of our share of the square footage of our in-service portfolio expiring (at our share).

During the third quarter of 2025, BXP continued to execute on the multi-year action plan introduced at our recent Investor Day held on September 8, 2025. The action plan focuses on growing Funds From Operations ("FFO") per share, funding development activity, and reducing our leverage. Our progress reflects steady advancement across each of these key priorities.

Growth in FFO per share depends in large part on the success of our leasing activity. Leasing momentum remained strong during the third quarter of 2025, as we signed leases for more than 1.5 million square feet during the quarter — or 39% greater than the third quarter of 2024 — driven by healthy corporate fundamentals and continued improvement in office utilization, particularly in our East Coast markets.

We are also making significant progress in raising capital to fund our development activity while reducing our leverage. Our plan contemplates generating approximately $1.9 billion of estimated net proceeds from the sales of 27 land, residential assets and non-strategic office assets by the end of 2027. There can be no assurance that we will complete any of these transactions on the terms and schedules currently contemplated or at all.

Consistent with our strategy to concentrate the portfolio in premier workplace assets in the CBDs of our gateway markets, we launched new developments at 343 Madison Avenue in New York City and 725 12th Street in Washington, D.C., while monetizing primarily suburban assets. Our development pipeline remains a key contributor to long-term growth, with eight active projects totaling approximately 3.5 million square feet and approximately $3.9 billion of BXP investment (at our share). Collectively, these initiatives underscore our disciplined approach to enhancing portfolio quality, strengthening the balance sheet, and positioning BXP for sustainable FFO growth over the next several years.

*Outlook*

BXP's leasing activity remains healthy and active across many of our core submarkets, supported by improving corporate sentiment and a continued rebound in office utilization. While conditions vary by region, we are encouraged by the breadth and depth of client demand in our premier assets, particularly in our East Coast markets.

Additionally, new construction of office space has slowed significantly, contributing to occupancy and rent growth in many submarkets in which we operate. Debt and equity investors are becoming constructive on the office sector resulting in more availability of capital at better pricing.

We remain focused on leveraging these positive trends by actively engaging with clients, deploying capital prudently, and positioning our portfolio to meet evolving demand for best-in-class, highly amenitized, and sustainable office environments.

*Leasing Activity and Occupancy*

Although all the markets in which we operate still need consistent incremental absorption to constitute a macro recovery, we continue to see pockets of strength where low availability is driving constructive client behavior. As clients choose premier workplaces in sound financial condition with building owners that are committed for the long term to their properties operated by the best property management teams, we expect to continue to be successful in gaining market share.

In the third quarter of 2025, we executed 79 leases totaling more than 1.5 million square feet and having a weighted-average lease term of approximately 7.9 years. This leasing volume represents our strongest third quarter since 2019, and a 39% increase from the third quarter of 2024.

At September 30, 2025, our total portfolio occupancy for the third quarter was 86.0%, a decrease of 40 basis points from the second quarter of 2025. As previously communicated, the addition of the 360 Park Avenue South, 1050 Winter Street and Reston Next Office Phase II developments to the in-service portfolio decreased the third quarter occupancy rate because each property has leases for which revenue recognition has not commenced in accordance with GAAP. Excluding the impact of placing these three properties in-service, total portfolio occupancy increased 20 basis points from the second quarter of 2025 to 86.6%.

Our portfolio percentage leased for the third quarter was 88.8% (including vacant space for which we have signed leases that have not yet commenced in accordance with GAAP). Excluding the impact of placing the three development properties in-service, the leased percentage increased by 10 basis points from the second quarter of 2025 to 89.2%.

An overview of the leasing activity in each of our regions for the three months ended September 30, 2025 is set forth in the table below. Amounts shown are in square feet, except for percentages, and include 100% of the unconsolidated joint venture properties.

*Investment Activity*

In the third quarter of 2025, we completed and fully placed in-service three development projects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 1050 Winter Street, an approximately 162,000 net rentable square foot office building located in Waltham, Massachusetts. The project is 100% leased.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reston Next Office Phase II, an approximately 87,000 net rentable square foot boutique premier workplace located in Reston, Virginia. The project is 92% leased.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 360 Park Avenue South, an approximately 450,000 net rentable square foot premier workplace located in New York City, New York. The project is 38% leased.

In addition, we commenced full vertical construction of 343 Madison Avenue in New York City, New York. 343 Madison Avenue will be a highly amenitized, sustainably designed, 46-story, 930,000 square foot premier workplace located on one of the best office development sites in Manhattan with direct access to Grand Central Station. We signed a letter of intent with a prospective client to lease approximately 274,000 square feet, or 30% of the building's square footage. We are in active discussions with other prospective clients, underscoring the continued strong demand for the future premier workplace. We believe 343 Madison represents a strong and significant value creation opportunity for shareholders.

**Critical Accounting Estimates**

Management's Discussion and Analysis of Financial Condition and Results of Operations discuss our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.

Our Annual Report on Form 10-K for the year ended December 31, 2024 contains a discussion of our critical accounting estimates. There have been no significant changes in our critical accounting estimates since the year ended December 31, 2024.

**Results of Operations**

At September 30, 2025 and 2024, we owned or had joint venture interests in a portfolio of 187 and 184 commercial real estate properties, respectively (in each case, the "Total Property Portfolio"). As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data with respect to the Total Property Portfolio provides a complete understanding of our operating results. Therefore, the comparison of operating results for the three and nine months ended September 30, 2025 and 2024 shows separately the changes attributable to the properties that were owned by us and in-service throughout each period compared (the "Same Property Portfolio") and the changes attributable to the properties included in the Acquired, Placed In-Service, In or Held for Development or Redevelopment or Sold Portfolios.

In our analysis of operating results, particularly to make comparisons of Net Operating Income ("NOI") between periods more meaningful, it is important to provide information for properties that were in-service and owned by us throughout each period presented. We refer to properties acquired or placed in-service prior to the beginning of the earliest period presented and owned by us and in-service through the end of the latest period presented as our Same Property Portfolio. The Same Property Portfolio therefore excludes properties acquired, placed in-service or in or held for development or redevelopment after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented.

NOI is a non-GAAP financial measure equal to net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership, as applicable, the most directly comparable GAAP financial measures, plus (1) net (income) loss attributable to noncontrolling interests, interest expense, loss from early extinguishment of debt, impairment losses, loss on sales-type lease, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) unrealized gain (loss) on non-real estate investments, gains from investments in securities, interest and other income (loss), gains on sales of real estate, income (loss) from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. We use NOI internally as a performance measure and believe it provides useful information to investors regarding our results of operations and financial condition because, when compared across periods, it reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. NOI presented by us may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.

We believe that in order to understand our operating results, NOI should be examined in conjunction with net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. NOI should not be considered as a substitute for net income (loss) attributable to BXP, Inc. or net income (loss) attributable to Boston Properties Limited Partnership (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.

Gains on sales of real estate, impairments and depreciation expense may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor redemptions of common units of limited partnership interest of BPLP ("OP Units"). This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties. The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in depreciation expense, impairment losses and gains on sales of real estate upon the sale of these properties. For additional information see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

**Results of Operations for the Nine Months Ended September 30, 2025 and 2024** 

Net income attributable to BXP, Inc. and net income attributable to Boston Properties Limited Partnership decreased by approximately $214.7 million and $236.2 million, respectively, for the nine months ended September 30, 2025 compared to 2024, as set forth in the following tables and for the reasons discussed below under the heading "*Comparison of the nine months ended September 30, 2025 to the nine months ended September 30, 2024"* within *"Item 2—Management's Discussion and Analysis of Financial Condition and Results of Operations."*

The following are reconciliations of (1) Net Income Attributable to BXP, Inc. to NOI and (2) Net Income Attributable to Boston Properties Limited Partnership to NOI for the nine months ended September 30, 2025 and 2024. For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 55.

_______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Rental Revenue is equal to Revenue less Development and Management Services Revenue and Direct Reimbursements of Payroll and Related Costs from Management Services Revenue per the Consolidated Statements of Operations, excluding the residential and hotel revenue that is noted below. We use Rental Revenue internally as a performance measure and in calculating other non-GAAP financial measures (e.g., NOI), which provide investors with information regarding our performance that is not immediately apparent from the most directly comparable GAAP measures and allows investors to compare operating performance between periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 55. Residential Net Operating Income for the nine months ended September 30, 2025 and 2024 is comprised of Residential Revenue of $37,725 and $37,027 less Residential Expenses of $18,570 and $17,413, respectively. Hotel Net Operating Income for the nine months ended September 30, 2025 and 2024 is comprised of Hotel Revenue of $37,532 and $38,080 less Hotel Expenses of $26,558 and $25,687, respectively, per the Consolidated Statements of Operations.

***<u>Same Property Portfolio</u>***

***Lease Revenue (Excluding Termination Income)***

Lease revenue (excluding termination income) from the Same Property Portfolio increased by approximately $34.7 million for the nine months ended September 30, 2025 compared to 2024. The increase was a result of our average revenue per square foot increasing by approximately $2.08, contributing approximately $53.3 million, partially offset by approximately $18.6 million due to our average occupancy decreasing from 89.0% to 88.3%.

***Termination Income***

Termination income decreased by approximately $5.5 million for the nine months ended September 30, 2025 compared to 2024.

Termination income for the nine months ended September 30, 2025 related to six clients across the Same Property Portfolio and totaled approximately $2.4 million.

Termination income for the nine months ended September 30, 2024 related to 23 clients across the Same Property Portfolio and totaled approximately $7.9 million.

***Parking and Other Revenue***

Parking and other revenue increased by approximately $0.6 million for the nine months ended September 30, 2025 compared to 2024. Parking revenue increased by approximately $1.7 million, partially offset by a decrease in other revenue of approximately $1.1 million. The increase in parking revenue was primarily due to an increase in monthly parking. The decrease in other revenue was primarily associated with a decrease in insurance proceeds.

***Real Estate Operating Expenses***

Real estate operating expenses from the Same Property Portfolio increased by approximately $25.7 million, or 2.8%, for the nine months ended September 30, 2025 compared to 2024, due primarily to increases in (1) repairs and maintenance of approximately $18.3 million, or 11.8% and (2) utilities of approximately $13.6 million, or 13.8%, partially offset by a decrease in other real estate operating expenses of approximately $6.2 million, or 0.9%. The increase in repairs and maintenance was primarily in the New York region. The increase in utilities was primarily in the Boston region.

***<u>Properties Acquired Portfolio</u>***

The table below lists the properties acquired between January 1, 2024 and September 30, 2025. Rental revenue and real estate operating expenses increased by approximately $0.4 million and $0.6 million, respectively, for the nine months ended September 30, 2025 compared to 2024, as detailed below.

&nbsp;&nbsp;&nbsp;&nbsp;(1)These properties are no longer considered "in-service" because each property's occupied percentage is less than 50% and we anticipate a future development/redevelopment of the property. A property will be considered held for development or redevelopment until the last client has vacated the property and the property is no longer revenue producing.

&nbsp;&nbsp;&nbsp;&nbsp;(2)This portion of Shady Grove Innovation District is comprised of two buildings, 2098 Gaither Road and 15825 Shady Grove Road.

_____________

&nbsp;&nbsp;&nbsp;&nbsp;(1)Average Monthly Rental Rate is calculated as the average of the quotients obtained by dividing (A) rental revenue as determined in accordance with GAAP, by (B) the number of occupied units for each month within the applicable fiscal period.

&nbsp;&nbsp;&nbsp;&nbsp;(2)Average Physical Occupancy is defined as (1) the average number of occupied units divided by (2) the total number of units, expressed as a percentage.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Average Economic Occupancy is defined as (1) total possible revenue less vacancy loss divided by (2) total possible revenue, expressed as a percentage. Total possible revenue is determined by valuing average occupied units at contract rates and average vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant units at their Market Rents, Average Economic Occupancy takes into account the fact that units of different sizes and locations within a residential property have different economic impacts on a residential property's total possible gross revenue. Market Rents used by us in calculating Economic Occupancy are based on the current market rates set by the managers of our residential properties based on their experience in renting their residential property's units and publicly available market data. Actual market rents and trends in such rents for a region as reported by others may vary materially from Market Rents used by us. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

***Hotel Net Operating Income***

The Boston Marriott Cambridge hotel had net operating income of approximately $11.0 million for the nine months ended September 30, 2025, representing a decrease of approximately $1.4 million compared to the nine months ended September 30, 2024.

***<u>Other Operating Revenue and Expense Items</u>***

***Development and Management Services Revenue***

Development and management services revenue increased by approximately $8.7 million for the nine months ended September 30, 2025 compared to 2024. Development services revenue and management services revenue increased by approximately $4.0 million and $4.7 million, respectively. The increase in development services revenue was primarily related to an increase in fees associated with a tenant improvement project in the Boston region. The increase in management services revenue was primarily related to leasing commissions earned from an unconsolidated joint venture and a third-party managed building in the New York region.

***General and Administrative Expense***

General and administrative expense increased by approximately $3.5 million for the nine months ended September 30, 2025 compared to 2024 primarily due to increases in compensation expense and other general and administrative expenses of approximately $2.5 million and $1.0 million, respectively.

Wages directly related to the development of rental properties are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the applicable asset or lease term. Capitalized wages for each of the nine months ended September 30, 2025 and 2024 were approximately $12.8 million and $13.2 million, respectively. These costs are not included in the general and administrative expenses discussed above.

***Transaction Costs***

Transaction costs increased by approximately $1.7 million for the nine months ended September 30, 2025 compared to 2024. In general, transaction costs relating to the formation of new joint ventures and the pursuit of other transactions are expensed as incurred.

***Direct Reimbursements of Payroll and Related Costs From Management Services Contracts and Payroll and Related Costs From Management Service Contracts***

We have determined that amounts reimbursed for payroll and related costs received from third parties in connection with management services contracts should be reflected on a gross basis instead of on a net basis as we have determined that we are the principal under these arrangements. We anticipate that these two financial statement line items will generally offset each other.

***<u>Other Income and Expense Items</u>***

***Income (Loss) from Unconsolidated Joint Ventures***

For the nine months ended September 30, 2025 compared to 2024, income (loss) from unconsolidated joint ventures decreased by approximately $160.2 million primarily due to the recognition of a non-cash impairment loss of approximately $145.1 million, partially offset by an approximately $2.2 million gain on the sale of Beach Cities Media Campus during the nine months ended September 30, 2025 (See Note 5 to the Consolidated Financial Statements). The decrease is also due to an approximately $21.8 million gain recognized from acquiring our joint venture partner's economic ownership interest in 901 New York Avenue during the nine months ended September 30, 2024, which did not recur during the nine months ended September 30, 2025.

***Gains on Sales of Real Estate***

&nbsp;&nbsp;&nbsp;&nbsp;(2)See Notes 3 and 5 to the Consolidated Financial Statements.

***Interest and Other Income (Loss)***

Interest and other income (loss) decreased by approximately $16.3 million for the nine months ended September 30, 2025 compared to 2024, due primarily to a decrease in our outstanding cash balances and corresponding lower interest income and an approximately $5.6 million reserve related to the unpaid default interest on one of our Related Party Notes Receivable (See Note 14 to the Consolidated Financial Statements).

***Gains from Investments in Securities***

Gains from investments in securities for the nine months ended September 30, 2025 and 2024 related to investments that we have made to reduce our market risk relating to deferred compensation plans that we maintain for BXP's officers and former non-employee directors. Under their respective deferred compensation plans, eligible officers and non-employee directors are permitted to defer a portion of their current compensation on a pre-tax basis and receive a tax-deferred return on the amounts deferred based on the performance of specific investments selected by participating officers and non-employee directors. In order to reduce our market risk relating to these plans, we typically acquire, in a separate account that is not restricted as to its use, similar or identical investments as those selected by each officer or non-employee director. This enables us to generally match our liabilities to participants under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains from investments in securities. During the nine months ended September 30, 2025 and 2024, we recognized gains of approximately $4.6 million and $4.8 million, respectively, on these investments. By comparison, our general and administrative expense decreased by approximately $4.6 million and $4.8 million during the nine months ended September 30, 2025 and 2024, respectively, as a result of decreases in our liability under our deferred compensation plans that was associated with the performance of the specific investments selected by participating officers and former non-employee directors of BXP.

***Unrealized Gain (Loss) on Non-Real Estate Investments***

We invest in non-real estate investments, which primarily consist of environmentally-focused investment funds. During the nine months ended September 30, 2025 and 2024, we recognized an unrealized gain (loss) of approximately $(0.3) million and $0.5 million, respectively, due to the observable changes in the fair value of the investments.

***Loss on Sales-Type Lease***

During the nine months ended September 30, 2025, we recognized approximately $2.5 million in additional costs, which had previously been contingent, related to a ground lease for land at our Reston Next property located in Reston, Virginia. We entered into the ground lease in 2020 with a third-party hotel developer and amended it in 2022. The amendment resulted in the derecognition of the assets related to the ground lease and the classification of the ground lease as a sales-type lease resulting in the recognition of a gain on sales-type lease of approximately $10.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;(2)See Note 6 to the Consolidated Financial Statements.

Interest expense directly related to the development of rental properties is capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed. Interest capitalized for the nine months ended September 30, 2025 and 2024 was approximately $36.0 million and $31.3 million, respectively. These costs are not included in the interest expense referenced above.

At September 30, 2025, our variable rate debt consisted of (1) BPLP's $2.95 billion unsecured credit facility ("2025 Credit Facility") and (2) BPLP's $750.0 million unsecured commercial paper program ("Commercial Paper Program"). The 2025 Credit Facility consists of (1) a revolving line of credit (the "Revolving Facility") of $2.25 billion and (2) an unsecured term loan facility (the "Term Loan Facility") of $700.0 million. As of September 30, 2025, there were $700.0 million and $750.0 million outstanding under the 2025 Credit Facility and Commercial Paper Program, respectively.

In addition, we have a $100.0 million unsecured term loan facility ("2024 Unsecured Term Loan") and $800.0 million of mortgage notes collateralized by Santa Monica Business Park and 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties that bear interest at variable rates, which have all been hedged with interest rates swaps to fix SOFR for all or a portion of the applicable debt term.

&nbsp;&nbsp;&nbsp;&nbsp;(1)The decrease was primarily attributable to an increase in repairs and maintenance expense.

&nbsp;&nbsp;&nbsp;&nbsp;(2)The decrease was primarily attributable to a decrease in lease revenue from our clients.

&nbsp;&nbsp;&nbsp;&nbsp;(3)On August 27, 2025, we acquired our partner's 45% ownership interest (See Note 9 to the Consolidated Financial Statements).

&nbsp;&nbsp;&nbsp;&nbsp;(4)Property was fully placed in service on October 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(5)Property is currently in development.

***Noncontrolling Interest—Common Units of the Operating Partnership***

For BXP, noncontrolling interest—common units of the Operating Partnership decreased by approximately $24.5 million for the nine months ended September 30, 2025 compared to 2024 due to a decrease in allocable income, which was the result of recognizing greater non-cash impairment losses during 2025, as well as a decrease in the noncontrolling interest's ownership percentage. Due to our ownership structure, there is no corresponding line item on BPLP's financial statements.

**Results of Operations for the Three Months Ended September 30, 2025 and 2024**

Net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership decreased approximately $205.3 million and $225.0 million, respectively, for the three months ended September 30, 2025 compared to 2024, as detailed in the following tables and for the reasons discussed below under the heading "*Comparison of the three months ended September 30, 2025 to the three months ended September 30, 2024" within "Item 2—Management's Discussion and Analysis of Financial Condition and Results of Operations.*"

The following are reconciliations of (1) Net Income (Loss) Attributable to BXP, Inc. to NOI and (2) Net Income (Loss) Attributable to Boston Properties Limited Partnership to NOI for the three months ended September 30, 2025 and 2024. For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 55.

_______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Rental Revenue is equal to Revenue less Development and Management Services Revenue and Direct Reimbursements of Payroll and Related Costs from Management Services Revenue per the Consolidated Statements of Operations, excluding the residential and hotel revenue that is noted below. We use Rental Revenue internally as a performance measure and in calculating other non-GAAP financial measures (e.g., NOI), which provide investors with information regarding our performance that is not immediately apparent from the most directly comparable GAAP measures and allows investors to compare operating performance between periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 55. Residential Net Operating Income for the three months ended September 30, 2025 and 2024 is comprised of Residential Revenue of $12,845 and $12,117 less Residential Expenses of $6,095 and $5,988, respectively. Hotel Net Operating Income for the three months ended September 30, 2025 and 2024 is comprised of Hotel Revenue of $13,162 and $15,082 less Hotel Expenses of $9,628 and $9,833, respectively, per the Consolidated Statements of Operations.

***<u>Same Property Portfolio</u>***

***Lease Revenue (Excluding Termination Income)***

Lease revenue (excluding termination income) from the Same Property Portfolio increased by approximately $13.3 million for the three months ended September 30, 2025 compared to 2024. The increase was a result of our average revenue per square foot increasing by approximately $1.80, contributing approximately $15.4 million, partially offset by approximately $2.1 million due to our average occupancy decreasing from 88.2% to 87.9%.

***Termination Income***

Termination income decreased by approximately $3.9 million for the three months ended September 30, 2025 compared to 2024.

Termination income for the three months ended September 30, 2025 related to three clients across the Same Property Portfolio and totaled approximately $1.2 million.

Termination income for the three months ended September 30, 2024 related to seven clients across the Same Property Portfolio and totaled approximately $5.1 million.

***Parking and Other Revenue***

Parking and other revenue increased by approximately $2.0 million for the three months ended September 30, 2025 compared to 2024. Parking and other revenue increased by approximately $0.6 million and $1.4 million, respectively. The increase in parking revenue was primarily due to an increase in monthly parking. The increase in other revenue is primarily associated with an increase in insurance proceeds.

***Real Estate Operating Expenses***

Real estate operating expenses from the Same Property Portfolio increased by approximately $2.3 million, or 0.7%, for the three months ended September 30, 2025 compared to 2024, due primarily to an increase in real estate operating expenses of approximately $9.0 million, or 5.3%, partially offset by a decrease in real estate taxes of approximately $6.7 million, or 4.6%. The decrease in real estate taxes was primarily due to tax abatements realized in the Los Angeles region.

***<u>Properties Placed In-Service Portfolio</u>***

The table below lists the properties that were placed in-service or partially placed in-service between July 1, 2024 and September 30, 2025. Rental revenue and real estate operating expenses from our Properties Placed In-Service Portfolio increased by approximately $13.1 million and $2.5 million, respectively, for the three months ended September 30, 2025 compared to 2024, as detailed below.

______________

&nbsp;&nbsp;&nbsp;&nbsp;(1)These properties are no longer considered "in-service" because each property's occupied percentage is less than 50% and we anticipate a future development/redevelopment of the property. A property will be considered held for development or redevelopment until the last client has vacated the property and the property is no longer revenue producing.

&nbsp;&nbsp;&nbsp;&nbsp;(2)Rental revenue for the three months ended September 30, 2024 includes approximately $6.4 million of termination income.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Reservoir Place is an approximately 526,000 square foot office building, of which approximately 165,000 square feet remains in-service. Rental revenue for the three months ended September 30, 2024 includes approximately $0.6 million of termination income.

_______________

&nbsp;&nbsp;&nbsp;&nbsp;(1)Average Monthly Rental Rate is calculated as the average of the quotients obtained by dividing (A) rental revenue as determined in accordance with GAAP, by (B) the number of occupied units for each month within the applicable fiscal period.

&nbsp;&nbsp;&nbsp;&nbsp;(2)Average Physical Occupancy is defined as (1) the average number of occupied units divided by (2) the total number of units, expressed as a percentage.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Average Economic Occupancy is defined as (1) total possible revenue less vacancy loss divided by (2) total possible revenue, expressed as a percentage. Total possible revenue is determined by valuing average occupied units at contract rates and average vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant units at their Market Rents, Average Economic Occupancy takes into account the fact that units of different sizes and locations within a residential property have different economic impacts on a residential property's total possible gross revenue. "Market Rents" used by us in calculating Average Economic Occupancy are based on the current market rates set by the managers of our residential properties based on their experience in renting their residential property's units and publicly available market data. Actual market rents and trends in such rents for a region as reported by others may vary materially from Market Rents used by us. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

***Hotel Net Operating Income***

The Boston Marriott Cambridge hotel had net operating income of approximately $3.5 million for the three months ended September 30, 2025, representing a decrease of approximately $1.7 million compared to the three months ended September 30, 2024.

***<u>Other Operating Revenue and Expense Items</u>***

***Development and Management Services Revenue***

Development and management services revenue increased by approximately $2.5 million for the three months ended September 30, 2025 compared to 2024. Development services revenue and management services revenue increased by approximately $1.2 million and $1.3 million, respectively. The increase in development services revenue was primarily related to an increase in fees associated with tenant improvement projects in the Boston and New York regions. The increase in management services revenue was primarily related to leasing commission fees earned from a third-party owned building in New York City.

***General and Administrative Expense***

General and administrative expense increased by approximately $2.8 million for the three months ended September 30, 2025 compared to 2024 primarily due to increases in compensation expense of approximately $2.5 million and approximately $0.3 million increase in other general and administrative expenses. The increase in compensation expense primarily related to an approximately $1.2 million increase in health insurance costs and an approximately $0.2 million increase in the value of our deferred compensation plan.

***Direct Reimbursements of Payroll and Related Costs From Management Services Contracts and Payroll and Related Costs From Management Service Contracts***

We have determined that amounts reimbursed for payroll and related costs received from third parties in connection with management services contracts should be reflected on a gross basis instead of on a net basis as we have determined that we are the principal under these arrangements. We anticipate that these two financial statement line items will generally offset each other.

***<u>Other Income and Expense Items</u>***

***Loss from Unconsolidated Joint Ventures***

For the three months ended September 30, 2025 compared to 2024, loss from unconsolidated joint ventures increased by approximately $141.3 million primarily due to the recognition of a non-cash impairment loss of approximately $145.1 million, partially offset by an approximately $2.2 million gain on the sale of Beach Cities Media Campus during the three months ended September 30, 2025 (See Note 5 to the Consolidated Financial Statements). These items did not occur during the three months ended September 30, 2024.

***Gains on Sales of Real Estate***

Gains on sales of real estate increased by approximately $1.4 million for the three months ended September 30, 2025 compared to 2024. For both periods the gains on sales related to the sale of real estate that occurred in prior periods.

***Interest and Other Income (Loss)***

Interest and other income (loss) decreased by approximately $6.8 million for the three months ended September 30, 2025 compared to 2024, due primarily to a decrease in our outstanding cash balances and corresponding lower interest income and an approximately $1.3 million reserve related to the unpaid default interest on one of our Related Party Notes Receivable (See Note 14 to the Consolidated Financial Statements).

***Gains from Investments in Securities***

Gains from investments in securities for the three months ended September 30, 2025 and 2024 related to investments that we have made to reduce our market risk relating to deferred compensation plans that we maintain for BXP's officers and former non-employee directors. Under their respective deferred compensation plans, eligible officers and non-employee directors are permitted to defer a portion of their current compensation on a pre-tax basis and receive a tax-deferred return on the amounts deferred based on the performance of specific investments selected by participating officers and non-employee directors. In order to reduce our market risk relating to these plans, we typically acquire, in a separate account that is not restricted as to its use, similar or identical investments as those selected by each officer or non-employee director. This enables us to generally match our liabilities to participants under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains from investments in securities. During the three months ended September 30, 2025 and 2024, we recognized gains of approximately $2.4 million and $2.2 million, respectively, on these investments. By comparison, our general and administrative expense increased by approximately $2.4 million and $2.2 million during the three months ended September 30, 2025 and 2024, respectively, as a result of increases in our liability under our deferred compensation plans that was associated with the performance of the specific investments selected by participating officers and former non-employee directors of BXP.

***Unrealized Gain on Non-Real Estate Investments***

We invest in non-real estate investments, which primarily consist of environmentally-focused investment funds. During the three months ended September 30, 2025 and 2024, we recognized an unrealized gain of approximately $178,000 and $94,000, respectively, due to the observable changes in the fair value of the investments.

***Impairment Losses***

During the three months ended September 30, 2025, in conjunction with our strategy to sell non-core assets, we evaluated our properties that were under negotiation for sale with third-parties (See Note 2 to the Consolidated Financial Statements). There were no impairment losses during the three months ended September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(1)Includes, if applicable, fair value and swap adjustments (See Note 7 to the Consolidated Financial Statements).

&nbsp;&nbsp;&nbsp;&nbsp;(2)See Note 6 to the Consolidated Financial Statements.

Interest expense directly related to the development of rental properties is capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed. Interest capitalized for the three months ended September 30, 2025 and 2024 was approximately $13.5 million and $11.6 million, respectively. These costs are not included in the interest expense referenced above.

At September 30, 2025, our variable rate debt consisted of (1) BPLP's $2.95 billion 2025 Credit Facility and (2) BPLP's $750.0 million Commercial Paper Program. The 2025 Credit Facility consists of (1) the $2.25 billion Revolving Facility and (2) the $700.0 million Term Loan Facility. As of September 30, 2025, there were $700.0 million and $750.0 million outstanding under the 2025 Credit Facility and Commercial Paper Program, respectively.

In addition, we have the $100.0 million 2024 Unsecured Term Loan and $800.0 million of mortgage notes collateralized by Santa Monica Business Park and 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties that bear interest at variable rates, which have all been hedged with interest rates swaps to fix SOFR for all or a portion of the applicable debt term.

For BXP, noncontrolling interest—common units of the Operating Partnership decreased by approximately $22.6 million for the three months ended September 30, 2025 compared to 2024 due primarily to a decrease in allocable income, which was the result of recognizing greater non-cash impairment losses during 2025, as well as a decrease in the noncontrolling interest's ownership. Due to our ownership structure, there is no corresponding line item on BPLP's financial statements.

**Liquidity and Capital Resources** 

***General***

Our principal liquidity needs for the next twelve months and beyond are to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund normal recurring expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• meet debt service and principal repayment obligations on maturing debt, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $100.0 million of principal outstanding on the 2024 Unsecured Term Loan due September 26, 2026, for which we have two, one-year extension options, subject to customary conditions,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.0 billion of 3.650% unsecured senior notes due February 1, 2026,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.0 billion of 2.750% unsecured senior notes due October 1, 2026 and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• amounts that become due under the Commercial Paper Program;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund capital calls from our unconsolidated joint venture investments to fund development costs, capital improvements, leasing costs and debt principal repayment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund mezzanine debt obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund development and redevelopment costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund capital expenditures, including major renovations, tenant improvements and leasing costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund possible acquisitions of properties, either directly or indirectly through the acquisition of equity interests; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• make the minimum distribution required to enable BXP to maintain its REIT qualification under the Code.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cash flow from operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• distributions of cash flows from joint ventures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cash and cash equivalent balances;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• borrowings under BPLP's Revolving Facility, unsecured term loans, short-term bridge facilities and construction loans (which may require guarantees by BPLP);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• long-term secured and unsecured indebtedness (including unsecured exchangeable indebtedness);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sales of real estate and interests in joint ventures owning real estate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• private equity sources, including institutional investors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• third-party fees generated by our property management, leasing, development and construction businesses; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• issuances of BXP equity securities and/or preferred or common units of partnership interests in BPLP.

We draw on multiple financing sources to fund our long-term capital needs. We use BPLP's 2025 Credit Facility primarily as a bridge facility to fund acquisition opportunities, refinance outstanding indebtedness, fund short-term development costs and for working capital. We also use BPLP's 2025 Credit Facility to backstop the Commercial Paper Program. Although we may seek to fund our development projects with construction loans, which may require guarantees by BPLP, the source of financing for each particular project ultimately depends on several factors, including, among others, the project's size and duration, whether the project is funded and owned by a joint venture, the extent of pre-leasing, our available cash and access to cost effective capital at the given time.

We seek to maximize income from our existing properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing client turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our property management, leasing, development and construction businesses, interest earned on cash deposits and, from time to time, the sale of assets. We believe these capital sources will continue to meet our short-term liquidity needs. A material adverse change in one or more sources of capital may adversely affect our net cash flows and our ability to repay or refinance existing indebtedness as it matures.

***Balance Sheet & Financing Activity***

On September 8, 2025, our Board of Directors declared a quarterly cash dividend of $0.70 per share of BXP common stock for the period of July 1, 2025 to September 30, 2025. This declaration reset the recurring quarterly dividend to $0.70 per share from $0.98 per share to, among other things, more closely align our annual dividend payout to our taxable income, allow us to retain incremental cash per quarter, and support longer-term growth.

On September 29, 2025, we completed the issuance of $1.0 billion aggregate principal amount of 2.00% exchangeable senior notes due October 1, 2030, generating approximately $940.1 million of net proceeds after deducting transaction costs, including costs related to entering into certain capped call agreements (See Note 6 to the Consolidated Financial Statements).

As of September 30, 2025, our share of unconsolidated joint venture debt maturing through November 2026 was approximately $325.4 million. This debt matures at different times through November 2026, and we expect to fund the repayment of this debt through a combination of refinancings, available cash balances, proceeds from asset sales, draws on BPLP's Revolving Facility, and/or proceeds from other secured or unsecured debt transactions.

As of October 31, 2025, we had available cash including proceeds from the $1.0 billion issuance of unsecured exchangeable senior notes completed on September 29, 2025 and interest earned on cash deposits of approximately $683.8 million (of which approximately $102.2 million was attributable to our consolidated joint venture partners). Our liquidity and capital resources depend on a wide range of factors, and we believe that our access to capital and our strong liquidity, including the approximately $1.5 billion available under BPLP's Revolving Facility (after deducting the $750.0 million being used as a backstop for the Commercial Paper Program) as of October 31, 2025, and our available cash are sufficient to fund our near term capital needs on existing development and redevelopment projects, repay our maturing indebtedness when due (if not refinanced or extended), satisfy our REIT distribution requirements (see "*REIT Tax Distribution Considerations"* below) and still allow us to act opportunistically on attractive investment opportunities.

------

<u>[**Table of Contents**](#ifba0473e2fbc413ba4e5193d63dc3952_10)</u>[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)[&nbsp;&nbsp;&nbsp;&nbsp;](#ifba0473e2fbc413ba4e5193d63dc3952_10)

From January 1, 2025 through October 31, 2025, we sold four properties for a gross sales price of approximately $63.6 million. Our share of the net proceeds from these sales was approximately $57.0 million in 2025.

We may seek to enhance our liquidity to fund our current and future development activity, pursue additional attractive investment opportunities and refinance or repay indebtedness. Depending on then-current interest rates, the overall conditions in the public and private debt and equity markets, and our existing and expected leverage at the time, we may decide to access one or more of these capital sources. Doing so may result in greater cash and cash equivalents pending our use of the proceeds.

We have not sold any shares under BXP's $600.0 million "at the market" equity offering program.

***Construction & Redevelopment Activities***

As of September 30, 2025, we have eight properties under development or redevelopment. Our share of the estimated total investment for these projects is approximately $3.9 billion, of which approximately $2.7 billion remains to be funded through 2031 (see table below for properties under construction/redevelopment). The commercial space in the pipeline, which excludes residential units, was approximately 43% pre-leased as of October 31, 2025.

***REIT Tax Distribution Considerations***

*Dividend* 

As a REIT, BXP is subject to a number of organizational and operational requirements, including a requirement that BXP currently distribute at least 90% of its annual taxable income (excluding capital gains and with certain other adjustments). Our policy is for BXP to distribute at least 100% of its taxable income, including capital gains, to avoid paying federal tax. BXP's Board of Directors will continue to evaluate BXP's dividend rate in light of our actual and projected taxable income (including gains on sales), liquidity requirements and other circumstances, and there can be no assurance that the future dividends declared by BXP's Board of Directors will not differ materially from the current quarterly dividend amount.

Holders of common and LTIP units (other than unearned MYLTIP units) of limited partnership interest in BPLP receive the same distribution per unit that is paid per share of BXP common stock.

*Sales* 

To the extent that we sell assets at a gain and cannot efficiently use the proceeds in a tax deferred manner for either our development activities or acquisitions, BXP would, at the appropriate time, decide whether it is better to declare a special dividend, adopt a stock repurchase program, reduce indebtedness or retain the cash for future investment opportunities. Such a decision will depend on many factors including, among others, the timing, availability and terms of development and acquisition opportunities, our then-current and anticipated leverage, the cost and availability of capital from other sources, the price of BXP's common stock and REIT distribution requirements. At a minimum, we expect that BXP would distribute at least that amount of proceeds necessary for BXP to avoid paying corporate level tax on the applicable gains realized from any asset sales.

From time to time in select cases, whether due to a change in use, structuring issues to comply with applicable REIT regulations or other reasons, we may sell an asset that is held by a taxable REIT subsidiary ("TRS"). Such a sale by a TRS would be subject to federal and local taxes.

***Cash Flow Summary***

The following summary discussion of our cash flows is based on the Consolidated Statements of Cash Flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Cash and cash equivalents and cash held in escrows aggregated approximately $938.7 million and $1.5 billion at September 30, 2025 and 2024, respectively, representing a decrease of approximately $532.8 million. The following table sets forth changes in cash flows:

---

|:---|:---|:---|:---|

| | **2025** | **2024** | **Change** |
| | **(in thousands)** | **(in thousands)** | **(in thousands)** |

| Net cash used in financing activities | (245644) | (141051) | (104593) |

---

Our principal source of cash flow is related to the operation of our properties. The weighted-average term of our in-place leases, including leases signed by our unconsolidated joint ventures, excluding residential units, was approximately 7.8 years as of September 30, 2025, with occupancy rates historically in the range of approximately 86% to 92%. Generally, our properties generate a relatively consistent stream of cash flows that provides us with resources to pay operating expenses, debt service and fund regular quarterly dividend and distribution payment requirements. In addition, over the past several years, we have raised capital through the sale of some of our properties and through secured and unsecured borrowings.

Cash is used in investing activities to fund acquisitions, development, net investments in unconsolidated joint ventures and maintenance and repositioning capital expenditures. Cash used in investing activities for the nine months ended September 30, 2025 and September 30, 2024 is detailed below:

Cash used in investing activities changed primarily due to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Construction in progress for the nine months ended September 30, 2025 included ongoing expenditures associated with Reston Next Office Phase II, Reston Next Retail and 1050 Winter Street, which were partially or fully placed in-service during the nine months ended September 30, 2025. In addition, we incurred costs associated with our continued development/redevelopment of 290 Binney Street, 121 Broadway, 725 12th Street and 343 Madison Avenue.

Construction in progress for the nine months ended September 30, 2024 included ongoing expenditures associated with 760 Boylston Street and 180 CityPoint, which were fully placed in-service during the nine months ended September 30, 2024, and 103 CityPoint that was partially placed in-service during 2023. In addition, we incurred costs associated with our continued development/redevelopment of Reston Next Office Phase II that was partially placed in-service, and 290 Binney Street, 300 Binney Street and 121 Broadway.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Building, pre-development and other capital improvements for the nine months ended September 30, 2025 and September 30, 2024 included approximately $39.4 million and $34.5 million, respectively, of pre-development expenditures associated with the 343 Madison Avenue project. Beginning July 31, 2025, costs associated with the continued development of 343 Madison Avenue are included within construction in progress.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Proceeds from sale of real estate for the nine months ended September 30, 2025 consisted of approximately $21.8 million of proceeds from the sale of the land at 17 Hartwell Avenue. On June 27, 2025, we entered into a new joint venture for the redevelopment of 17 Hartwell Avenue (See Notes 3 and 5 to the Consolidated Financial Statements).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)On January 8, 2024, we completed the acquisition of our joint venture partner's 50% economic ownership interest in the joint venture that owns 901 New York Avenue, located in Washington, DC, for a gross purchase price of $10.0 million and we acquired net working capital, including cash and cash equivalents of approximately $16.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Capital contributions to unconsolidated joint ventures for the nine months ended September 30, 2025 consisted primarily of cash contributions of approximately $31.9 million, $24.3 million, $21.2 million and $14.1 million to our 290 Coles Street, 360 Park Avenue South, 751 Gateway, and 200 Fifth Avenue joint ventures, respectively. On March 5, 2025, we entered into a new joint venture for the development of 290 Coles Street (See Note 5 to the Consolidated Financial Statements).

Capital contributions to unconsolidated joint ventures for the nine months ended September 30, 2024 consisted primarily of cash contributions of approximately $27.5 million, $25.2 million, $11.8 million and $11.5 million to our 360 Park Avenue South, Gateway Commons, Platform 16 and Dock 72 joint ventures, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)Capital distributions from unconsolidated joint ventures for the nine months ended September 30, 2025 consisted of cash distributions totaling approximately $29.2 million from our Beach Cities Media Campus joint venture resulting from excess proceeds from the sale of the property.

Cash used in financing activities for the nine months ended September 30, 2025 totaled approximately $245.6 million. This amount consisted primarily of the repayment of BPLP's $850.0 million in aggregate principal amount of its 3.200% unsecured senior notes due January 15, 2025 and the payment of our regular dividends and distributions to our shareholders and unitholders, partially offset by the net proceeds from the issuance of BPLP's $1.0 billion in aggregate principal amount of its 2.00% unsecured exchangeable senior notes. The unsecured exchangeable senior notes are due October 2030 and net proceeds, including the purchase of the Capped Call Transactions, totaled approximately $940.1 million. Future debt payments are discussed below under the heading *"Debt.*"

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of leverage commonly used by analysts in the REIT sector. We present this measure as a percentage and it is calculated by dividing (A) our consolidated debt by (B) our consolidated market capitalization, which is the market value of our outstanding equity securities plus our consolidated debt. Consolidated market capitalization is the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;our consolidated debt; plus

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;the product of (x) the closing price per share of BXP common stock on September 30, 2025, as reported by the New York Stock Exchange, multiplied by (y) the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) &nbsp;&nbsp;&nbsp;&nbsp;the number of outstanding shares of common stock of BXP,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) &nbsp;&nbsp;&nbsp;&nbsp;the number of outstanding OP Units in BPLP (excluding OP Units held by BXP),

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) &nbsp;&nbsp;&nbsp;&nbsp;the number of OP Units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) &nbsp;&nbsp;&nbsp;&nbsp;the number of OP Units issuable upon conversion of 2012 OPP Units, and 2013 - 2022 MYLTIP Units that were issued in the form of LTIP Units.

The calculation of consolidated market capitalization does not include LTIP Units issued in the form of MYLTIP Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2023 - 2025 MYLTIP Units are not included in this calculation as of September 30, 2025.

We also present BXP's Share of Market Capitalization and BXP's Share of Debt/BXP's Share of Market Capitalization, which are calculated in the same manner, except that BXP's Share of Debt is utilized instead of our consolidated debt in both the numerator and the denominator. BXP's Share of Debt is defined as our consolidated debt plus our share of debt from our unconsolidated joint ventures (calculated based upon our ownership percentage), minus our partners' share of debt from our consolidated joint ventures (calculated based upon the partners' percentage ownership interests adjusted for basis differentials). Management believes that BXP's Share of Debt provides useful information to investors regarding our financial condition because it includes our share of debt from unconsolidated joint ventures and excludes our partners' share of debt from consolidated joint ventures, in each case presented on the same basis. We have several significant joint ventures and presenting various measures of financial condition in this manner can help investors better understand our financial condition and/or results of operations after taking into account our economic interest in these joint ventures. We caution investors that the ownership percentages used in calculating BXP's Share of Debt may not completely and accurately depict all of the legal and economic implications of holding an interest in a consolidated or unconsolidated joint venture. For example, in addition to partners' interests in profits and capital, venture agreements vary in the allocation of rights regarding decision making (both for routine and major decisions), distributions, transferability of interests, financing and guarantees, liquidations and other matters. Moreover, in some cases we exercise significant influence over, but do not control, the joint venture in which case GAAP requires that we account for the joint venture entity using the equity method of accounting and we do not consolidate it for financial reporting purposes. In other cases, GAAP requires that we consolidate the venture even though our partner(s) own(s) a significant percentage interest. As a result, management believes that the presentation of BXP's Share of a financial measure should not be considered a substitute for, and should only be considered with and as a supplement to our financial information presented in accordance with GAAP.

We present these supplemental ratios because our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes and because different investors and lenders consider one or both of these ratios. Investors should understand that these ratios are, in part, a function of the market price of the common stock of BXP and as such will fluctuate with changes in such price, and they do not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. However, for a company like BXP, whose assets are primarily income-producing real estate, these ratios may provide investors with an alternate indication of leverage, so long as they are evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.

_______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)For the unsecured senior notes, the GAAP rate represents the yield on issuance date including the effects of discounts on the notes, settlements of interest rate contracts and the amortization of financing costs. For all other debt, the GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, the effects of hedging transactions (if any and excluding capped calls classified as equity) and adjustments required under ASC 805 "Business Combinations" to reflect loans and swaps at their fair values (if any).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)No principal amounts are due prior to maturity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)This unsecured senior note was repaid at maturity, see Note 6 to the Consolidated Financial Statements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)At September 30, 2025, the weighted average interest rate of the commercial paper notes outstanding was approximately 4.51% per annum and had a weighted-average maturity of 43 days from the date of issuance. At October 31, 2025, BPLP had an aggregate of $750.0 million of commercial paper notes outstanding that bore interest at a weighted-average rate of approximately 4.29% per annum and had a weighted-average maturity of 26 days, from the date of issuance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)The unsecured line of credit bears interest at a variable rate of SOFR+0.85% per annum. The 2025 Credit Facility is used as a backstop for the $750.0 million Commercial Paper Program. As such, BPLP intends to maintain, at a minimum, availability under the unsecured line of credit in an amount equal to the amount of unsecured commercial paper notes outstanding. The table below provides the principal indebtedness outstanding and remaining capacity under the unsecured line of credit at September 30, 2025 and October 31, 2025 (dollars in thousands).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)The 2024 Unsecured Term Loan bears interest at a variable rate of SOFR+1.05% per annum. BPLP entered into an interest rate swap contract to fix SOFR at a weighted-average fixed interest rate of 3.6775% per annum for the period commencing on April 7, 2025 and ending on April 6, 2026. Stated interest rate reflects the weighted-average fixed interest rate based on the interest rate swap contracts plus 1.05% per annum. The 2024 Unsecured Term Loan has two one-year extension options, subject to certain conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7)The Unsecured Term Loan Facility bears interest at a variable rate of SOFR+0.95% per annum and has two six-month extension options, each subject to customary conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8)The mortgage loan requires interest only payments with a balloon payment due at maturity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9)In connection with the refinancing of the loan, we guaranteed the consolidated entity's obligation to fund various reserves for tenant improvement costs and allowances, leasing commissions and free rent obligations in lieu of cash deposits. As of September 30, 2025, the maximum funding obligation under the guarantee was approximately $6.4 million. We earn a fee from the joint venture for providing the guarantee and have an agreement with our partners to reimburse the joint venture for their share of any payments made under the guarantee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10)The mortgage loan bears interest at a variable rate of Daily Simple SOFR+1.60% per annum. BPLP entered into an interest rate swap contract to fix Daily Simple SOFR at a weighted-average fixed interest rate of 3.6775% per annum for the period commencing on April 7, 2025 and ending on April 6, 2026. Stated interest rate reflects the weighted-average fixed interest rate based on the interest rate swap contracts plus 1.60% per annum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11)The mortgage loan bears interest at a variable rate of Daily Compounded SOFR+2.25% per annum. BPLP entered into three interest rate swap contracts with notional amounts aggregating $600.0 million to fix Daily Compounded SOFR at a weighted-average fixed interest rate of 3.7925% for the period commencing on December 15, 2023 and ending on October 26, 2028. The stated interest rate reflects the weighted average fixed interest rate based on the interest rate swap contracts plus 2.25% per annum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)The GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, the effects of hedging transactions (if any and excluding capped calls classified as equity) and adjustments required under ASC 805 "Business Combinations" to reflect loans and swaps at their fair values (if any).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)The unsecured commercial paper notes are included in our floating rate debt statistics. At September 30, 2025, the weighted average interest rate of the unsecured commercial paper notes outstanding was approximately 4.51% per annum and had a weighted-average maturity of 43 days from the date of issuance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)The Fixed Rate Debt includes the effects of hedging transactions.

***Derivative Instruments and Hedging Activities***

As of September 30, 2025, we had $900.0 million of interest rate swaps outstanding, where hedge accounting was elected, with a fair value of approximately $(8.5) million. On April 8, 2025, we entered into an interest rate swap contract with a notional amount of $300.0 million to replace $300.0 million of interest rate swaps that expired on April 1, 2025. For a description of these interest rate swaps, see Note 7 to the Consolidated Financial Statements.

***Investment in Unconsolidated Joint Ventures - Secured Debt***

We have investments in unconsolidated joint ventures with our effective ownership interests ranging from approximately 19% to approximately 71%. Sixteen of these ventures have mortgage indebtedness. We exercise significant influence over, but do not control, these entities. As a result, we account for them using the equity method of accounting. See also Note 5 to the Consolidated Financial Statements. At September 30, 2025, the aggregate carrying amount of debt, including both our and our partners' share, incurred by these ventures was approximately $3.2 billion (of which our proportionate share is approximately $1.4 billion). The table below summarizes the outstanding debt of these joint venture properties at September 30, 2025. In addition to other guarantees specifically noted in the table, we have agreed to customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) as well as the completion of development projects on certain of the loans.

*State and Local Tax Matters* 

Because BXP is organized and qualifies as a REIT, it is generally not subject to federal income taxes, but is subject to certain state and local taxes. In the normal course of business, certain entities through which we own real estate either have undergone, or are currently undergoing, tax audits or other inquiries. Although we believe that we have substantial arguments in favor of our position in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. Collectively, tax deficiency notices received to date from the jurisdictions conducting the ongoing audits have not been material. However, there can be no assurance that future audits will not occur with increased frequency or that the ultimate result of such audits will not have a material adverse effect on our results of operations.

*Funds from Operations*

Pursuant to the revised definition of FFO adopted by the Board of Governors of the National Association of Real Estate Investment Trusts ("Nareit"), we calculate FFO for each of BXP and BPLP by adjusting net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership (computed in accordance with GAAP), respectively, for gains (or losses) from sales of properties, including a change in control, impairment losses on depreciable real estate consolidated on our balance sheet, impairment losses on our investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures and our share of real estate-related depreciation and amortization. FFO is a non-GAAP financial measure. We believe the presentation of FFO, combined with the presentation of required GAAP financial measures, improves the understanding of operating results of REITs among the investing public and helps make comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for understanding and comparing our operating results because, by excluding gains and losses related to sales or a change in control of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on historical cost accounting and useful life estimates), FFO can help investors compare the operating performance of a company's real estate across reporting periods and to the operating performance of other companies.

Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current Nareit definition or that interpret the current Nareit definition differently. We believe that in order to facilitate a clear understanding of our operating results, FFO should be examined in conjunction with net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. FFO should not be considered as a substitute for net income (loss) attributable to BXP, Inc. or net income (loss) attributable to Boston Properties Limited Partnership (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.

**Material Cash Commitments**

We have various service contracts with vendors related to our property management. In addition, we enter into other contracts in the ordinary course of business that may extend beyond one year. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties. Contract terms are generally between three and five years.

During the three months ended September 30, 2025, we paid approximately $133.4 million to fund tenant-related obligations, including tenant improvements and leasing commissions.

In addition, during the three months ended September 30, 2025, we and our unconsolidated joint venture partners incurred approximately $114.3 million of new tenant-related obligations associated with approximately 1.4 million square feet of second generation leases, or approximately $82 per square foot. During the three months ended September 30, 2025, we signed approximately 133,100 square feet of first generation leases. The tenant-related obligations for the development properties are included within the projects' "Estimated Total Investment" referred to in *"Item 2—Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources."* In aggregate, during the three months ended September 30, 2025, we signed leases for approximately 1.5 million square feet of space and incurred aggregate tenant-related obligations of approximately $134.4 million, or approximately $88 per square foot.

**ITEM 3—*Quantitative and Qualitative Disclosures about Market Risk.***

We are exposed to certain market risks, one of the most predominant of which is a change in interest rates. Unless we have entered into interest rate swaps or other derivatives to fix the interest rate, increases in interest rates can result in increased interest expense under our 2025 Credit Facility, 2024 Unsecured Term Loan, Commercial Paper Program, certain mortgage loans and other debt that bears interest at variable rates. Increases in interest rates can also result in increased interest expense when our fixed rate debt matures and needs to be refinanced.

As of September 30, 2025, approximately $14.3 billion of our indebtedness bore interest at fixed rates and therefore the fair value of these instruments is not affected by changes in the market interest rates. The remaining approximately $2.3 billion of outstanding indebtedness bore interest at variable rates, including approximately $800.0 million of unsecured term loans, $750.0 million of borrowings under the Commercial Paper Program and approximately $800.0 million of secured debt. However, we have entered into interest rate swaps with notional amounts aggregating $800.0 million for our secured debt and $100.0 million for BPLP's 2024 Unsecured Term Loan, thus fixing the interest rates for all or a portion of the applicable debt term (See Note 7 to the Consolidated Financial Statements for information pertaining to interest rate swap contracts). Therefore, as of September 30, 2025, we had approximately $1.4 billion of variable rate debt outstanding.

The following table presents our aggregate debt obligations carrying value, estimated fair value and where applicable, the corresponding weighted-average GAAP interest rates sorted by maturity date as of September 30, 2025.

The table below does not include our unconsolidated joint venture debt. For a discussion concerning our unconsolidated joint venture debt, including interest rate swaps, see Note 5 to the Consolidated Financial Statements and "*Item 2*—*Management's Discussion and Analysis of Financial Condition and Results of Operations*—*Liquidity and Capital Resources—Investment in Unconsolidated Joint Ventures - Secured Debt.*"

At September 30, 2025, the weighted-average stated interest rates on the fixed rate debt stated above was 3.59% per annum. At September 30, 2025, our outstanding variable rate debt totaled approximately $2.3 billion, of which $900.0 million was subject to interest rate swaps. At September 30, 2025, the weighted-average stated interest rate on our variable rate debt, including the effect of the interest rate swaps, was 5.22% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.9 million and $17.6 million for the three and nine months ended September 30, 2025, respectively.

Our use of derivative instruments also involves certain additional risks such as counterparty credit risk, the enforceability of hedging contracts and the risk that unanticipated and significant changes in interest rates will cause a significant loss of basis in the contract. We believe that there is a low likelihood that these counterparties will fail to meet their obligations and we minimize our exposure by limiting counterparties to major banks who meet established credit and capital guidelines. There can be no assurance that we will adequately protect against the foregoing risks.

The fair value amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions, we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.
