解說說明

本報告結合BXP, Inc.和Boston Properties Limited Partnership截至2024年9月30日的第10-Q表的季度報告。除非另有說明或情況另有要求，“BXP”一詞指的是BXP, Inc.（前身為Boston Properties, Inc.） ，一家註冊於特拉華州的房地產投資信托（REIT），而“BPLP”和“營運合夥企業”一詞指的是Boston Properties Limited Partnership, 一家註冊於特拉華州的有限合夥企業。BPLP是通過該企業BXP大量進行業務，並且直接或通過子公司擁有大部分資產。BXP是BPLP的唯一普通合夥人，也是BPLP的有限合夥人之一。作為BPLP的唯一普通合夥人，BXP擁有對BPLP日常管理的獨家控制。因此，除非另有說明或情況需要，對“公司”，“我們”，“我們”和“我們”的引用一起指的是BXP，BPLP和BXP共同控股的子公司。

截至2024年9月30日，BXP擁有BPLP約89.6%的所有權利益。剩餘的約10.4%權益由有限合夥人擁有。 BPLP的其他有限合夥人：(1)以其直接或間接的資產利益交換為BPLP的普通有限合夥股權，或(2)根據BXP的股票期權和激勵計劃，收到BPLP的長期激勵計劃單位，或兩者兼而有之。 根據BPLP的有限合夥協議，單位持有人可隨時出示其BPLP的普通單位進行贖回（受限於當時發行單位時同意的限制，該限制可能限制此權利一段時間，通常為從發行之日起一年）。 出示普通單位進行贖回時，BPLP必須以與BXP普通股相等的現金金額贖回該單位。 然而，在BPLP不以現金方式贖回的情況下，BXP可以選擇以發行BXP普通股來收購提供的通過普通單位。 如果BXP這樣選擇，其普通股將按一比一的比例與普通單位進行交換。 此一對一交換比率經過指定的調整，以防止稀釋。 BXP通常預計每次表示將選擇發行其普通股以贖回，而不是由BPLP支付現金。 在每次這樣的交換或贖回時，BXP對BPLP的所有權百分比將增加。 此外，每當BXP發行其普通股以外的股票而不是為了收購BPLP的普通單位時，BXP必須將收到的任何淨收益供應給BPLP，並且BPLP必須向BXP發行等於BXP所發行普通股數量的BPLP的普通單位數。 這種結構通常被稱為傘狀合夥REIt，或UPREIt。

本公司認為將BXP和BPLP的季度報告合併成一份報告：

•讓投資者能夠以與管理層相同的方式查看並運作整個業務，提高對BXP和BPLP的理解。

•省略重複披露內容，提供更簡明易讀的介紹，因為許多披露適用於BXP和BPLP兩者。

•透過準備一份合併報告，而非兩份分開的報告，可以節省時間和成本。

公司認為了解BXP和BPLP在BXP和BPLP作為一個合併公司運作的背景下之間的一些差異是重要的。 BPLP的財務業績已合併入BXP的基本報表中。 除了對BPLP的投資外，BXP沒有任何其他重要資產、負債或業務，也沒有自己的員工。 除了涉及BXP證券的交易以外，一般由BPLP執行所有重要的業務關係，而非由BXP執行。 BPLP基本上持有BXP的所有資產，包括對子公司和合資企業的所有權利益。 BPLP執行業務的業務並結構化為一個沒有公開交易股權的合夥企業。 除了來自BXP的股權發行淨收益（該收益以普通股或優先股份配對或適用於BPLP的股份形式出售以交換為BPLP的合夥企業），BPLP產生公司業務所需的所有其他資本資金。 這些資源包括營運活動提供的運營資本，信貸擔保及無擔保借款，以及來自某些物業出售和合資企業的權益出售所收到的款項。

股東權益、合夥人資本和非控制權益是BXP和BPLP綜合財務報表之間的主要區別。 BPLP的有限合夥人在BPLP的財務報表中被計算為合夥人資本，在BXP的財務報表中被計算為非控制權益。 BPLP財務報表中的非控制權益包括各種綜合夥伴關係中非聯屬合夥人的權益。 BXP財務報表中的非控制權益包括相同的

BPLP的非控制權益和BPLP的有限合夥人。股東權益和合夥人資本之間的差異是由於BXP和BPLP發行的股權不同。

此外，由於BXP和BPLP此前應用收購會計準則，其合併基本報表中的房地產資產總額有所不同，原因是BXP為在與BPLP普通單位的非贊助者贖回相關的普通股發行所遭遇的房地產資產進行了賬面上的增值。此種會計處理導致在此類贖回時BXP的房地產資產踰而成為而BPLP的淨房地產相比截至2024年9月30日約為23780萬美元，約佔1.2％，並導致折舊費用、減值虧損和在出售具有房地產增值配額的資產時的房地產轉讓收益之間的差異。由於在2009年公司採納了要求任何後續贖回僅作為權益交易核算的新會計標準，這種收購會計處理從2009年開始被視為前瞻性的無效。

為了幫助投資者更好地了解BXP和BPLP之間的主要差異，此報告中的以下項目分別呈現了有關BXP和BPLP的信息：

• 項目1. 基本報表（未經審核），其中包括以下針對BXP和BPLP的具體披露：

• 備註 3。房地產業;

• Note 10. 股東權益 / 合夥人資本；

• 附註11.區隔資訊；

• 附註 12. 每股盈利 / 普通股單位；以及

• 項目 2. 管理者的財務 控制項和業績和流動性及資本資源的討論與分析，包含適用於每個實體的具體資訊。

該報告還包括BXP和BPLP各自的單獨第I部分 - 第4條。控制和程序以及第II部分 - 第2條。未註冊的股權證券銷售和款項使用節，以及BXP和BPLP各自的單獨展示31和32號證書。

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, 2024, owned an approximate 89.6% (89.4% at December 31, 2023) 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:

•common units of partnership interest (also referred to as “OP Units”) and

•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 restrictions 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 has previously granted LTIP Units in the form of (1) 2012 outperformance plan awards (“2012 OPP Units”) and (2) 2013 - 2024 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 - 2021 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 2022 - 2024 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units and the 2013 - 2021 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 2022 - 2024 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units and the earned 2013 - 2021 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, 2024, the Company owned or had joint venture interests in a portfolio of 184 commercial real estate properties (the “Properties”) aggregating approximately 53.0 million net rentable square feet of primarily office properties, including nine properties under construction/redevelopment totaling approximately 2.7 million net rentable square feet. At September 30, 2024, the Properties consisted of:

•162 office and life sciences properties (including six properties under construction/redevelopment);

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

•seven residential properties (including two properties under construction); and

•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.

Table of Contents

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, 2023.

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 nine entities that are VIEs as of September 30, 2024 and has determined that it is the primary beneficiary for all of these entities as of September 30, 2024.

Consolidated Variable Interest Entities

As of September 30, 2024, BXP has identified nine consolidated VIEs, including BPLP. Excluding BPLP, the consolidated VIEs consisted of (i) the following five in-service properties: 767 Fifth Avenue (the General Motors Building), Times Square Tower, 601 Lexington Avenue, Atlantic Wharf Office Building and 100 Federal Street, (ii) 343 Madison Avenue, which is categorized as land held for future development and (iii) 290 Binney Street and 300 Binney Street, which are currently under development / redevelopment (See Note 14).

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.

Variable Interest Entities Not Consolidated

As of September 30, 2024, the Company does not have any unconsolidated joint ventures that are classified as VIEs.

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, 2024 and December 31, 2023, the financial instruments that are being valued for disclosure purposes, as well as the Level at which they are categorized as defined in Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures” (“ASC 820”).

_______________

(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, 2024 and December 31, 2023, the Company had outstanding three-month United States Treasury Bills with a maturity date of November 21, 2024 and January 30, 2024, respectively, that were classified as held to maturity because the Company determined that it had the positive intent and ability to hold to maturity. Because these securities are considered short-term investments, they are reflected at amortized cost within Cash and Cash Equivalents on the Consolidated Balance Sheets. At September 30, 2024 and December 31, 2023, the amortized cost of these securities were approximately $175.9 million and $302.7 million, respectively.

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

The Company’s investment in non-real estate investments is shown within Prepaid and Other Assets on the Consolidated Balance Sheets and was approximately $6.7 million and $4.6 million at September 30, 2024 and December 31, 2023, respectively. The non-real estate investments utilize net asset value as the practical expedient.

_______________

(1) Per the guidance in ASC 326 “Financial Instruments — Credit Losses” (“ASC 326”), the Company concluded that the risk of nonpayment is nonexistent because the U.S. Government has a long history with no credit losses and, therefore, no credit loss allowance was recorded.

At March 31, 2024, the Company evaluated the expected hold period for a portion of its Shady Grove property, consisting of 2 Choke Cherry Road, 2094 Gaither Road and a land parcel, located in Rockville, Maryland. Based on a shorter-than-expected hold period, the Company reduced the carrying value of a portion of the property that the Company anticipates selling to a third-party developer to its estimated fair value at March 31, 2024. As a result, during the nine months ended September 30, 2024, each of BXP and BPLP recognized an impairment loss of approximately $13.6 million. The Company’s estimated fair value utilized Level 3 inputs and was based on a pending offer from a third party (See Note 3).

Recurring Fair Value

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.

Interest rate swaps						$	(10,191)					$	1,976

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 officers and non-employee directors of BXP to defer a portion of the officer’s current income or the non-employee director’s current compensation on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer or non-employee director. 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, 2024 and December 31, 2023, the Company had maintained approximately $38.9 million and $36.1 million, respectively, in separate accounts, which are not restricted as to their use. The Company recognized gains (losses) of approximately $2.2 million and $(0.9) million on its investments in the accounts associated with the Company’s deferred compensation plans during the three months ended September 30, 2024 and September 30, 2023, respectively, and approximately $4.8 million and $2.3 million during the nine months ended September 30, 2024 and September 30, 2023, respectively, primarily due to the observable change in fair value.

Acquisition

On January 8, 2024, the Company completed the acquisition of its joint venture partner’s 50% economic ownership interest in the joint venture that owns 901 New York Avenue, located in Washington, DC. At acquisition, the total net equity acquired was $20.0 million, which includes $10.0 million in cash that the Company paid for the joint venture partner's 50% economic ownership interest in the joint venture. The property is subject to existing mortgage indebtedness of approximately $207.1 million (See Note 6). The acquisition resulted in the Company recording a gain upon consolidation of approximately $21.8 million, which is the difference between the fair value of the previously held equity method investment immediately prior to the consolidation of $10.0 million, less the Company’s costs basis of approximately $(11.8) million. The gain on consolidation is included within income (loss) from unconsolidated joint ventures in the Consolidated Statement of Operations.

The total net assets acquired is equal to (1) the total net equity acquired of $20.0 million, which includes $10.0 million in cash that the Company paid for the joint venture partner's 50% economic ownership interest in the joint venture plus (2) $207.1 million of debt assumed, less (3) net working capital acquired of approximately $7.1 million.

Pending Disposition and Impairment

At March 31, 2024, the Company evaluated the expected hold period for a portion of its Shady Grove property, consisting of 2 Choke Cherry Road, 2094 Gaither Road and a land parcel, located in Rockville, Maryland. Based on a shorter-than-expected hold period, the Company reduced the carrying value of a portion of the property that the Company anticipates selling to a third-party developer to its estimated fair value at March 31, 2024. As a result, each of BXP and BPLP recognized an impairment loss of approximately $13.6 million during the nine months ended September 30, 2024. The Company’s estimated fair value was based on Level 3 inputs as defined in ASC 820 and on a pending offer from a third-party.

On May 7, 2024, the Company entered into an agreement with the third-party developer for the sale of 2 Choke Cherry Road, 2094 Gaither Road and the land parcel for an aggregate gross sale price of approximately $24.8 million. On July 22, 2024, the Company executed an amendment to the agreement for an aggregate gross sale price of approximately $24.7 million. 2 Choke Cherry Road and 2094 Gaither Road are two vacant office properties aggregating approximately 143,000 net rentable square feet that were taken out of service and held for redevelopment. The disposition is subject to satisfaction of certain closing conditions and there can be no assurance that this transaction will be consummated on the terms currently contemplated or at all.

Lessee

On March 28, 2024, the Company entered into a 90-year air rights lease with the Massachusetts Department of Transportation for an approximately 61,000 square foot site at the parking garage located at 100 Clarendon Street and the concourse level of the Massachusetts Bay Transportation Authority’s Back Bay Station (the “Station”). The lease requires annual base rental payments of $250,000 until the commencement of construction, as defined in the lease. If the Company commences construction of a project on the site on or before August 1, 2028, then a final fixed rental payment is due in accordance with the lease at that time. After August 1, 2028, if the Company commences construction of a project on the site, then a final rental payment based on the then current fair market value will be due at that time. In addition, the lease requires annual payments of $500,000 through 2033 to fund maintenance and improvements to the Station. The Company has assumed that it will begin construction on the site on or before August 1, 2028. The incremental borrowing rate for this lease is 6.57% per annum. The net present value of the ground lease payments is approximately $23.2 million. The Company classifies this lease as an operating lease. As a result, the Company recorded a Right of Use Assets – Operating Leases and Lease Liabilities – Operating Leases of approximately $23.9 million and $23.2 million, respectively, on its Consolidated Balance Sheets at March 31, 2024. The ground lease had operating lease costs of approximately $87,000 for the three months ended September 30, 2024 and approximately $0.2 million for the period from March 28, 2024 through September 30, 2024.

The following table provides a maturity analysis for the air rights operating lease as of March 28, 2024 (in thousands):

The Company has a ground lease for the land underlying its residential property, The Skylyne, in Oakland, California. The Skylyne is a residential property consisting of 402 residential units and supporting retail space totaling approximately 331,000 net rentable square feet. The ground lease has approximately 92-years remaining (including extension options) and provides the Company with the right to purchase the land subject to certain conditions. When the lease was executed in 2017, the purchase option was considered a bargain purchase option

and, as a result, the Company classified it as a finance lease and the Company assumed the lessor would exercise its right to require the Company to purchase the land in May 2024 for approximately $38.7 million. In May 2024 and as of the date of this report, the lessor has not exercised this option and the Company reassessed the accounting for the ground lease and determined that the purchase option continues to be considered a bargain purchase option and the ground lease will continue to be accounted for as a finance lease. The lease requires monthly base rental payments of a nominal amount until the purchase occurs, which the Company now estimates will be in 2030. As a result of the reassessment, the lease liability was remeasured and reduced to approximately $0.1 million. In conjunction with the reduction in the lease liability, the right of use asset was reduced to $0 and the difference between the lease liability and right of use asset of approximately $9.5 million was recorded as a decrease to interest expense for the nine months ended September 30, 2024. There can be no assurance that this transaction will be consummated on the terms currently contemplated or at all.

On February 1, 2024, BPLP repaid $700.0 million in aggregate principal amount of its 3.800% senior notes due February 1, 2024. The repayment was completed with available cash and the $600.0 million proceeds from the mortgage loan entered into on October 26, 2023. The repayment price was approximately $713.3 million, which was equal to the stated principal plus approximately $13.3 million of accrued and unpaid interest to, but not including, the repayment date. Excluding the accrued and unpaid interest, the repayment price was equal to the principal amount being repaid.

On August 26, 2024, BPLP completed a public offering of $850.0 million in aggregate principal amount of its 5.750% unsecured senior notes due 2035. The notes were priced at 99.961% of the principal amount to yield an effective rate (including financing fees) of approximately 5.842% per annum to maturity. The notes will mature on January 15, 2035, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $841.9 million after deducting underwriting discounts and transaction expenses.

Unsecured Credit Facility

BPLP’s unsecured revolving credit facility (the “2021 Credit Facility”) provides for borrowings of up to $2.0 billion, as described below in this Note 6, through BPLP’s revolving facility, subject to customary conditions. The 2021 Credit Facility matures on June 15, 2026 and includes a sustainability-linked pricing component. Under the 2021 Credit Facility, BPLP had the option to increase the original total commitment of $1.5 billion by up to an additional $500.0 million by increasing the amount of the Revolving Facility and/or by incurring one or more term loans, in each case, subject to syndication of the increase and other conditions (the “Accordion Option”). On September 28, 2023, BPLP exercised a portion of the Accordion Option which increased the then maximum borrowing amount under the 2021 Credit Facility from $1.5 billion to $1.815 billion. On April 29, 2024, BPLP exercised the remainder of the Accordion Option and further increased the maximum borrowing amount under the 2021 Credit Facility to $2.0 billion. All other terms of the 2021 Credit Facility remain unchanged.

Table of Contents

At September 30, 2024, BPLP had no amount outstanding under the 2021 Credit Facility. The 2021 Credit Facility is used as a backstop for BPLP’s $500.0 million unsecured commercial paper program (See “Unsecured Commercial Paper” below). As such, BPLP intends to maintain, at a minimum, availability under the 2021 Credit Facility in an amount equal to the amount of unsecured commercial paper notes outstanding.

Unsecured Term Loans

On January 4, 2023, BPLP entered into a credit agreement that provided for a $1.2 billion unsecured term loan facility (the “2023 Unsecured Term Loan”). Upon entry into the credit agreement, BPLP exercised its option to draw $1.2 billion under the 2023 Unsecured Term Loan.

On April 29, 2024, BPLP repaid $500.0 million of the outstanding balance under the 2023 Unsecured Term Loan from the proceeds of its unsecured commercial paper program (See “Unsecured Commercial Paper” below). At September 30, 2024, BPLP had $700.0 million of principal outstanding under the 2023 Unsecured Term Loan.

Under the credit agreement governing the 2023 Unsecured Term Loan, BPLP may, at any time prior to the maturity date, increase total commitments by up to an additional $300.0 million in aggregate principal amount by increasing the existing 2023 Unsecured Term Loan or incurring one or more additional term loans, in each case, subject to syndication of the increase and other conditions. The 2023 Unsecured Term Loan had an initial maturity date of May 16, 2024, with one 12-month extension option, subject to customary conditions. On May 16, 2024, BPLP exercised its option to extend the maturity date of the 2023 Unsecured Term Loan to May 16, 2025. All other terms of the 2023 Unsecured Term Loan remain unchanged.

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”) with a lender (the “Lender”) under the mortgage loan collateralized by the Company’s Santa Monica Business Park properties located in Santa Monica, California (the “SMBP Loan”). Upon entry into the credit agreement, BPLP exercised its option to draw $100.0 million under the 2024 Unsecured Term Loan. The proceeds were used to repay the portion of the SMBP Loan held by the Lender. After the repayment, the SMBP Loan had a remaining principal balance of $200.0 million (See Note 14). The 2024 Unsecured Term Loan matures on September 26, 2025 with three, one-year extension options, subject to customary conditions.

At BPLP’s option, loans under the 2024 Unsecured Term Loan will bear interest at a rate per annum equal to (1) a base rate equal to the highest of (a) zero, (b) Prime Rate, (c) the Federal Funds effective rate plus 0.50%, and (d) Term SOFR for a one-month period plus 1.10%, in each case, plus a margin ranging from 0 to 60 basis points based on BPLP’s credit rating; or (2) a rate equal to adjusted Term SOFR or Daily Simple SOFR with a one-month period plus a margin ranging from 75 to 160 basis points based on BPLP’s credit rating.

Based on BPLP’s September 30, 2024 credit rating, the 2024 Unsecured Term Loan bears interest at a rate equal to Daily Simple SOFR plus 1.05% per annum. The 2024 Unsecured Term Loan is subject to an existing interest rate swap to fix Daily Simple SOFR at a fixed rate of approximately 2.688% per annum for a period that ends on April 1, 2025 (See Note 7). At September 30, 2024, BPLP had $100.0 million of principal outstanding under the 2024 Unsecured Term Loan.

The 2023 and 2024 Unsecured Term Loans contain 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 any outstanding amount under the 2023 and 2024 Unsecured Term Loans. Among other covenants, the 2023 and 2024 Unsecured Term Loans require that BPLP maintain on an ongoing basis: (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 year, (2) a secured debt leverage ratio not to exceed 55%, (3) a fixed charge coverage ratio of at least 1.40 to 1.00, (4) an unsecured debt leverage ratio not to exceed 60%, however, the unsecured debt leverage ratio may increase to no greater than 65% provided that it is reduced to 60% within one year, (5) an unsecured debt interest coverage ratio of at least 1.75 to 1.00 and (6) limitations on permitted investments. At September 30, 2024, BPLP was in compliance with each of these financial and other covenant requirements.

Unsecured Commercial Paper

On April 17, 2024, BPLP established an unsecured commercial paper program. 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 $500.0 million with varying maturities of up to one year. Amounts available

Table of Contents

under the unsecured 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 2021 Credit Facility. At September 30, 2024, BPLP had an aggregate of $500.0 million of unsecured commercial paper notes outstanding that bore interest at a weighted-average rate of approximately 5.22% per annum and had a weighted-average maturity of 34 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, 2024, the Company had not posted any collateral related to the agreements.

Effective Hedge Instruments

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 incur ineffectiveness during the three and nine months ended September 30, 2024.

BPLP’s and SMBP LLC’s derivative contracts consisted of the following at September 30, 2024 (dollars in thousands):

Derivative Instrument						Aggregate Notional Amount																		Strike Rate Range												Balance Sheet Location
												Effective Date						Maturity Date						Low						High												Fair Value
BPLP:
Interest Rate Swaps						$	600,000					December 15, 2023						October 26, 2028						3.790		%	—			3.798		%				Other liabilities						$	(12,600)
Interest Rate Swaps						100,000						September 27, 2024						April 1, 2025						2.688		%	—			2.688		%				Prepaid expenses and other assets						799

_______________

(1)A consolidated subsidiary of the Company that is the borrower under the mortgage loan collateralized by its Santa Monica Business Park property.

The following table presents the location in the financial statements of the gains or (losses) recognized as a result of the Company’s cash flow hedges for the three and nine months ended September 30, 2024 and 2023 (in thousands):

						Three months ended September 30,												Nine months ended September 30,

(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.

Ineffective Hedging Instruments

During the year ended December 31, 2023, to satisfy a lender requirement, the Company entered into two agreements with the same third-party to purchase and sell a $600.0 million interest rate cap. The Company did not elect hedge accounting, and as such, any change in market value will be recognized in Gain (losses) from interest rate contracts in the Consolidated Statement of Operations. For the three and nine months ended September 30, 2024 and 2023, the Company recognized no impact to its Consolidated Statement of Operations from entering into these agreements.

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 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 total approximately $21.0 million at September 30, 2024.

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, either the Company or its partners may be entitled to receive an additional promoted interest or payments.

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 refinancing of 767 Fifth Avenue’s (the General Motors Building) secured loan by the Company’s consolidated joint venture entity, 767 Venture, LLC, the Company 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, 2024, the maximum funding obligation under the guarantee was approximately $6.4 million. The Company earns a fee from the joint venture for providing the guarantee and has an agreement with the outside partners to reimburse the joint venture for their share of any payments made under the guarantee. As of September 30, 2024, no amounts related to the guarantee were recorded as liabilities in the Company’s consolidated financial statements.

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, 2024, the Company has funded approximately $3.9 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 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 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. In February 2024, the court granted the seller’s motion for summary judgement interpreting certain sections of the agreement in favor of the seller’s claims. The Company is disputing 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 significantly greater than its established accrual.

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.

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 alleges 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 alleges 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.

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.

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, which means that the appeal will be decided by the full panel. A date has not yet been set for the full panel hearing.

Insurance

The Company’s property insurance program per occurrence limits are $1.0 billion for its portfolio insurance program, including coverage for acts of terrorism other than nuclear, biological, chemical or radiological terrorism (“Terrorism Coverage”). The Company also carries $1.35 billion of property insurance in excess of the $1.0 billion of coverage in the Company’s property insurance program for 601 Lexington Avenue, New York, New York, consisting

35

---

Table of Contents

of $750 million of property and Terrorism Coverage in excess of the Company’s property insurance program and $600 million of Terrorism Coverage only in excess of the $1.75 billion of coverage. Certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), are currently insured in separate insurance programs. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including Terrorism Coverage. The Company also currently carries nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) (“NBCR Coverage”), which is provided by IXP as a direct insurer, for the properties in the Company’s portfolio, including 767 Fifth Avenue, but excluding certain other properties owned in joint ventures with third parties or which the Company manages. The per occurrence limit for NBCR Coverage is $1.0 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage provided by IXP is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” The program trigger is $200 million, the coinsurance is 20% and the deductible is 20% of the premiums earned by the insurer for the year prior to a claim. If the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIA. The Company may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if TRIA is not extended after its expiration on December 31, 2027, if there is a change in its portfolio or for any other reason. The Company intends to continue to monitor the scope, nature and cost of available terrorism insurance.

The Company also currently carries earthquake insurance on its properties located in areas known to be subject to earthquakes. Specifically, the Company currently carries earthquake insurance which covers its San Francisco and Los Angeles regions with a $330 million per occurrence limit, and a $330 million annual aggregate limit, $30 million of which is provided by IXP, as a direct insurer. This insurance is subject to a deductible in the amount of 5% of the value of the affected property. In addition, the Company currently carries earthquake insurance which covers its Seattle region with a $110 million per occurrence limit, and a $110 million annual aggregate limit. This insurance is subject to a deductible in the amount of 2% of the value of the affected property. The amount of the Company’s earthquake insurance coverage may not be sufficient to cover losses from earthquakes. In addition, the amount of earthquake coverage could impact the Company’s ability to finance properties subject to earthquake risk. The Company may discontinue earthquake insurance or change the structure of its earthquake insurance program on some or all of its properties in the future if the premiums exceed the Company’s estimation of the value of the coverage.

IXP, a captive insurance company which is a wholly-owned subsidiary of the Company, acts as a direct insurer with respect to a portion of the Company’s earthquake insurance coverage for its Greater San Francisco and Los Angeles properties and the Company’s NBCR Coverage. Insofar as the Company owns IXP, it is responsible for its liquidity and capital resources, and the accounts of IXP are part of the Company’s consolidated financial statements. In particular, if a loss occurs which is covered by the Company’s NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. IXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and its insurance policy is maintained after the payout by the Federal Government. If the Company experiences a loss and IXP is required to pay under its insurance policy, the Company would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, BPLP has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.

The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism, earthquakes, pandemics and cybersecurity incidents, in particular, but the Company cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars, for which the Company cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes, pandemics or other catastrophic events, if the Company experiences a loss that is uninsured or that exceeds policy limits, the Company could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that the Company could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect the Company’s business, financial condition and results of operations.

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, 2024, the noncontrolling interests in BPLP consisted of the following:

OP Units						LTIP Units (1)						2022 MYLTIP Units						2023 MYLTIP Units						2024 MYLTIP Units
15,926,014						2,336,797						252,151						322,053						330,479

__________

(1)Includes 617,961 LTIP Units earned by employees under the Company’s multi-year long-term incentive awards granted between 2012 and 2021 (i.e., 2012 OPP and 2013 - 2021 MYLTIP awards).

Noncontrolling Interest—Common Units

During the nine months ended September 30, 2024, 951,881 OP Units were presented by the holders for redemption (including an aggregate of 105,814 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, 2024, BPLP had outstanding the 2022 - 2024 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 2022 - 2024 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 agreed to the number of 2022 - 2024 MYLTIP Units that are earned, less the distributions actually paid during the performance period on all of the awarded 2022 - 2024 MYLTIP Units.

On February 1, 2024, the measurement period for the Company’s 2021 MYLTIP awards ended and, based on BXP’s absolute and relative TSR performance, the final payout was determined to be 112% of target, or an aggregate of approximately $12.6 million (after giving effect to employee separations). As a result, an aggregate of 155,625 2021 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 2024 and during the nine months ended September 30, 2023:

Record Date						Payment Date						Distributions per OP Unit and LTIP Unit						Distributions per MYLTIP Unit
September 30, 2024						October 31, 2024						$0.98						$0.098
June 28, 2024						July 31, 2024						$0.98						$0.098
March 28, 2024						April 30, 2024						$0.98						$0.098
December 29, 2023						January 30, 2024						$0.98						$0.098
September 29, 2023						October 31, 2023						$0.98						$0.098
June 30, 2023						July 31, 2023						$0.98						$0.098
March 31, 2023						April 28, 2023						$0.98						$0.098
December 30, 2022						January 30, 2023						$0.98						$0.098

A holder of an OP Unit may present the OP Unit to BPLP for redemption at any time (subject to restrictions 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. The value of the OP Units (other than OP Units owned by BXP), and LTIP Units (including the 2012 OPP Units and 2013 - 2021 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, 2024 was approximately $1.5 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 $1.9 billion and $1.6 billion at September 30, 2024 and December 31, 2023, respectively, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.

On March 21, 2024, the Company completed the sale of a 45% interest in 290 Binney Street in Cambridge, Massachusetts.  The institutional investor funded approximately $97.2 million in cash at closing, which is less than 45% of the agreed upon carrying value of the property immediately prior to the transaction.  The institutional investor will fund all construction costs until its equity balance is proportionate to its ownership percentage, after which the Company and the institutional investor will fund the development project based on their respective ownership interests.  The Company retains a 55% ownership interest in the joint venture.  The transaction did not qualify as a sale of real estate for financial reporting purposes as the Company continues to effectively control the property and thus will continue to account for the property on a consolidated basis in its financial statements and no gain was recognized in the Consolidated Statements of Operations.  The Company provides customary development, property management and leasing services to the joint venture. 

The Company has accounted for the transaction as an equity transaction and as of March 21, 2024 has recognized noncontrolling interest in its Consolidated Balance Sheets totaling approximately $104.6 million, which is equal to 45% of the aggregate carrying value of the total equity of the property immediately prior to the transaction.  The difference between the cash proceeds received and the noncontrolling interest recognized, which was approximately $7.5 million, has been reflected as a decrease in additional paid-in capital in the Company’s Consolidated Balance Sheets.  At the end of each reporting period, there will be a reallocation of the partners’ equity balances such that the ending balance in each partners’ capital account reflects each partners’ claim on net assets. These adjustments will impact additional paid-in capital and noncontrolling interest in property partnerships in the Company’s Consolidated Balance Sheets. For the three and nine months ended September 30, 2024, the adjustment was approximately $(27.1) million and $7.8 million, respectively. 

290 Binney Street is an approximately 573,000 net rentable square foot laboratory/life sciences development project located in Cambridge, Massachusetts.  The  development project is 100% pre-leased to a life sciences company.  

10. Stockholders’ Equity / Partners’ Capital

As of September 30, 2024, BXP had 157,979,898 shares of Common Stock outstanding.

As of September 30, 2024, BXP owned 1,762,427 general partnership units and 156,217,471 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, 2024, BXP issued 951,881 shares of Common Stock in connection with the redemption of an equal number of redeemable OP Units from limited partners.

Company’s share of Net Operating Income						$	498,510					$	490,999					$	1,489,103					$	1,473,449

Net operating income (“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, impairment loss, 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 investment, gains (losses) 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. The Company believes NOI is useful to investors as a performance measure and believes it provides useful information to investors 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. 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 the Company may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.

Table of Contents

The Company’s internal reporting utilizes its share of NOI, which includes its share of NOI from consolidated and unconsolidated joint ventures, which is a non-GAAP financial measure that is calculated as the consolidated amount, plus the Company’s share of the amount from the Company’s unconsolidated joint ventures (calculated based upon the Company’s economic percentage ownership interest and, in some cases, after priority allocations), less the Company’s partners’ share of the amount from the Company’s consolidated joint ventures (calculated based upon the partners’ economic percentage ownership interests and, in some cases, after priority allocations, income allocation to private REIT shareholders and their share of fees due to the Company). The Company’s share of NOI from unconsolidated joint ventures, as defined above, also does not include its share of loss from early extinguishment of debt, unrealized gain (loss) on derivative instruments, gain on sale / consolidation, gain on investment, and impairment losses on investments, all of which are included within Income (Loss) from Unconsolidated Joint Ventures in the Company’s Consolidated Statements of Operations.  Management utilizes its share of NOI in assessing its performance as the Company has several significant joint ventures and, in some cases, the Company exercises significant influence over, but does not control, the joint venture, in which case GAAP requires that the Company account for the joint venture entity using the equity method of accounting and the Company does not consolidate it for financial reporting purposes. In other cases, GAAP requires that the Company consolidate the venture even though the Company’s partner(s) owns a significant percentage interest. As a result, the presentations of the Company’s share of NOI should not be considered a substitute for, and should only be considered together with and as a supplement to, the Company’s financial information presented in accordance with GAAP.

Asset information by segment is not reported because the Company does not use this measure to assess performance. Therefore, depreciation and amortization expense is not allocated among segments. Interest expense, impairment loss, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts, corporate general and administrative expense, unrealized gain (loss) on non-real estate investment, gains (losses) 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 are not included in NOI and are provided as reconciling items to the Company’s reconciliations of its share of NOI to net income.

The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by geographic area. 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.

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 - 2021 MYLTIP Units required, and the 2022 - 2024 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 stock options, restricted stock and other securities of BPLP that are exchangeable for BXP’s Common Stock, 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. Participating securities are included in the computation of basic earnings per common unit using the two-class method. Participating securities are included in the computation of diluted earnings per common unit using the if-converted method if the impact is dilutive. Because the 2012 OPP Units and 2013 - 2021 MYLTIP Units required, and the 2022 - 2024 MYLTIP Units require, BXP to outperform certain performance thresholds, unless such thresholds have been met by the end of the applicable reporting period, BPLP excludes such units from the diluted earnings per common unit calculation. Other potentially dilutive common units 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 17,721,000 and 18,002,000 redeemable common units for the three months ended September 30, 2024 and 2023, respectively, and 18,119,000 and 17,928,000 redeemable common units for the nine months ended September 30, 2024 and 2023, respectively.

13. Stock Option and Incentive Plan

On January 25, 2024, the Compensation Committee of BXP’s Board of Directors approved the grant of 2024 Multi-Year Long-Term Incentive Program (the “2024 MYLTIP”) awards under the Boston Properties, Inc. 2021 Stock Incentive Plan (the “2021 Plan”) to certain executive officers of BXP. The 2024 MYLTIP awards consists of three components. Two of the components, each weighted 40%, utilize BXP’s TSR over a three-year measurement period as the performance metrics and the third component utilizes a leverage ratio as the performance metric. Earned awards will range from zero to a maximum of 330,479 LTIP Units depending on BXP’s performance under the three components, with a target of approximately 165,240 LTIP Units. Under ASC 718 “Compensation - Stock Compensation,” the 2024 MYLTIP awards have an aggregate value of approximately $11.1 million.

On February 1, 2024, the measurement period for the Company’s 2021 MYLTIP awards ended and, based on BXP’s absolute and relative TSR performance, the final payout was determined to be 112% of target, or an aggregate of approximately $12.6 million (after giving effect to employee separations). As a result, an aggregate of 155,625 2021 MYLTIP Units that had been previously granted were automatically forfeited.

During the nine months ended September 30, 2024, BXP issued 83,316 shares of restricted common stock and BPLP issued 451,044 LTIP Units and 330,479 2024 MYLTIP Units to employees and non-employee directors under the 2021 Plan. Employees and non-employee directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit and 2024 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

Table of Contents

granted during the nine months ended September 30, 2024 were valued at approximately $5.3 million. The LTIP Units granted were valued at approximately $26.7 million using a Monte Carlo simulation method model. Because the 2012 OPP Units and 2013 - 2024 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 $4.0 million and $4.8 million for the three months ended September 30, 2024 and 2023, respectively, and $38.5 million and $45.7 million for the nine months ended September 30, 2024 and 2023, respectively. At September 30, 2024, there was (1) an aggregate of approximately $25.4 million of unrecognized compensation expense related to unvested restricted stock and LTIP Units and (2) an aggregate of approximately $(40,000) of unrecognized compensation expense related to unvested 2022 - 2024 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.5 years.

14. Subsequent Events

On October 5, 2024, the Company fully placed in-service 103 CityPoint, an approximately 113,000 net rentable square foot laboratory/life sciences project located in Waltham, Massachusetts.

On October 8, 2024, the Company modified the mortgage loan collateralized by its Santa Monica Business Park properties located in Santa Monica, California. The mortgage loan had an outstanding principal balance of $200.0 million, bore interest at a variable rate equal to Daily Simple SOFR + 1.38% per annum and was scheduled to mature on July 19, 2025 (See Note 6). The modified loan is scheduled to mature on October 8, 2028 and continues to bear interest at a variable rate equal to Daily Simple SOFR + 1.38% per annum until July 19, 2025. Beginning July 19, 2025, the mortgage loan will bear interest at Daily Simple SOFR + 1.60% per annum through the maturity date. The entire principal is subject to interest rate swap contracts to fix Daily Simple SOFR at a weighted-average fixed interest rate of approximately 2.675% per annum through April 1, 2025 (See Note 7). The mortgage loan requires monthly interest-only payments during the term of the loan, with the entire principal due at maturity. Santa Monica Business Park is an office park consisting of 21 buildings totaling approximately 1.2 million net rentable square feet.

On October 31, 2024, the Company completed and fully placed in-service 300 Binney Street, a laboratory/life sciences redevelopment project with approximately 236,000 net rentable square feet located in Cambridge, Massachusetts. The property is fully leased to a life sciences tenant.

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 vary 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 and trends 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 risks and uncertainties related to adverse changes in general economic and capital market conditions, including inflation, increases in interest rates, supply chain disruptions, labor market disruptions, dislocation and volatility in capital markets, and potential longer-term changes in consumer and client behavior, sustained changes in client preferences and space utilization, as well as the other important factors below and the risks described in (i) our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 including those described under the caption “Risk Factors,” (ii) our subsequent filings under the Exchange Act and (iii) the risk factors set forth in this Form 10-Q in Part II, Item 1A.

Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

•volatile or adverse global economic and geopolitical conditions, health crises and dislocations in the credit markets could adversely affect economic conditions and/or restrict our access to cost-effective capital, which could have a material adverse effect on our business opportunities, results of operations and financial condition;

•general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases on attractive terms, changes in client preferences and space utilization, dependence on clients’ financial condition, and competition from other developers, owners and operators of real estate);

•failure to manage effectively our growth and expansion into new markets and sub-markets or to integrate acquisitions and developments successfully;

•the ability of our joint venture partners to satisfy their obligations;

•risks and uncertainties affecting property development and construction (including, without limitation, supply chain disruptions, labor shortages, construction delays, increased construction costs, cost overruns, inability to obtain necessary permits, client accounting considerations that may result in negotiated lease provisions that limit a client’s liability during construction, and public opposition to such activities);

•risks associated with the availability and terms of financing and the use of debt to fund acquisitions and developments or refinance existing indebtedness, including the impact of higher interest rates on the cost and/or availability of financing;

Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all risk factors, nor can we assess the impact of all risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not unduly rely on forward-looking statements as a prediction of actual results. Investors should also refer to our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q for future periods and Current Reports on Form 8-K as we file them with the SEC, and to other materials we may furnish to the public from time to time through Current Reports on Form 8-K or otherwise, for a discussion of risks and uncertainties that may cause actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements. We expressly disclaim any responsibility to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events, or otherwise, and you should not rely upon these forward-looking statements after the date of this report.

Overview

BXP is one of the largest publicly traded office real estate investment trusts (REITs) (based on total market capitalization as of September 30, 2024) in the U.S. 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. 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. We generate revenue and cash primarily by leasing premier workplaces to our clients. 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, 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 commitment to the office asset class and to our clients as many competitors disinvest in the sector, a strong balance sheet with access to capital in the secured and unsecured debt and 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.

Table of Contents

Today, clients and their advisors are more focused than ever on these attributes for their building owners, which distinguishes BXP among its competitors.

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.

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 that helps BXP distinguish itself from competitors as our clients are interested in leasing space in vibrant, amenitized and accessible premier workplaces to encourage more in-person work. This interest has accelerated the flight to quality in the office industry. 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 approximately 90% of our share of net operating income (“NOI”) comes from predominantly premier workplaces located in CBDs. As of September 30, 2024, these CBD assets are 90.1% occupied and 92.1% leased (including vacant space for which we have signed leases that have not yet commenced in accordance with generally accepted accounting principles (“GAAP”)). For a detailed discussion of our share of NOI, including the reasons management believes the metric is useful to investors and a reconciliation to the most comparable GAAP measure, see page 39.

As of September 30, 2024, the weighted-average remaining lease term (1) for our in-place leases, based on square feet, including those signed by our unconsolidated joint ventures but excluding residential units, was approximately 7.6 years, and (2) for our 20 largest clients, based on square feet, was approximately 10.0 years.

Outlook

We believe the most important market forces driving occupancy, rental rates and earnings for BXP are interest rates, corporate earnings growth, return-to-office behaviors, and outperformance of premier workplaces, all of which are currently trending in BXP’s favor, serving as tailwinds for BXP’s performance.

In particular, corporate earnings growth is an important driver for BXP’s performance given its correlation to leasing activity. After remaining flat for all of 2023, S&P 500 earnings, which are viewed as a proxy for corporate health, are expected to grow 9.9% in 2024. Our experience tells us that companies with earnings growth are much more likely to invest, hire and expand their leased space, as demonstrated in BXP’s growing leasing volumes this year. We do not currently see evidence of a looming recession in the decision-making of our clients.

Return-to-office behaviors continue to improve in the cities in which we operate. Several large companies have recently announced more stringent in-office work requirements for their employees, and 84% of the CEOs surveyed in a recent third-party study believe there will be a full return-to-office work at their companies within three years, up from 64% of those surveyed just one year ago. The reasons cited by the CEOs include concerns about diminished collaboration, innovation and productivity, inadequate supervision and training for younger employees, and the cost of maintaining vacant offices.

The evolving operating environment impacts various aspects of our operating activities as:

•labor market conditions shift, which has gradually increased employer demand for mandatory in-person workdays;

52

---

Table of Contents

•volatility in the capital markets has led companies to be more reticent in their capital outlays and slowed down decision-making, including capital required for leasing new space;

•private market debt financing, both for construction and existing assets, is significantly more challenging to arrange; and

•construction costs have increased and, although much of the cost for our active development pipeline is fixed, the cost of potential future construction activity continues to increase.

In light of the uncertain trajectory of the U.S. and global economies, we continue to position BXP for success by ensuring ample liquidity, managing our leverage, pursuing additional capital raising opportunities and maintaining discipline in discretionary capital expenditures, while continuing to selectively invest (including through both acquisitions and developments) in premier workplace opportunities. We remain focused on:

•continuing to embrace our leadership position in the premier workplace segment and leveraging our strength in portfolio quality, client relationships, development skills, market penetration and sustainability to profitably build market share;

•leasing available space in our in-service and development properties, as well as proactively focusing on future lease expirations;

•completing the construction and leasing of our development properties;

•pursuing attractive asset class adjacencies where we have a track record of success, such as life sciences and residential development;

•continuing to enhance the overall quality of our portfolio and actively recycling capital by selling assets, subject to market conditions, that we believe no longer fit within our portfolio strategy or could attract premium pricing in the current market;

•actively managing our operations in a sustainable and responsible manner; and

•prioritizing risk management by actively managing liquidity, investing more extensively with joint venture partners to manage our debt levels, and being highly selective in new investment commitments.

The following is an overview of leasing and investment activity in the third quarter of 2024 and recent business highlights.

Leasing Activity and Occupancy

To be successful in any leasing environment, we believe we must consider all aspects of the client-landlord relationship. In this regard, we believe that our competitive leasing advantage is based on the following attributes:

•our understanding of our client’s short- and long-term space utilization and amenity needs in the local markets;

•our track record of developing and operating premier workplaces in a sustainable and responsible manner;

•our reputation as a high-quality developer, owner and manager of premier workplaces in our markets;

•our financial strength, including our ability to fund our share of lease obligations and maintain premier building standards; and

•our relationships with local brokers.

Overall, the environments in which we operate are improving. Although all the markets in which we operate still need consistent incremental absorption to constitute a macro recovery, we have started 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 2024, we executed 74 leases totaling more than 1.1 million square feet with a weighted-average lease term of approximately 7.2 years. We signed leases for a total of approximately 3.3 million square feet in the first three quarters of 2024, representing a 25% increase compared to the same period in 2023.

Table of Contents

BXP’s CBD portfolio was 90.1% occupied and 92.1% leased (including vacant space for which we have signed leases that have not yet commenced in accordance with GAAP) at September 30, 2024. Approximately 90% of our share of NOI comes from assets located in our CBD portfolio, underscoring the strength of BXP’s strategy to invest in the highest quality buildings in dynamic urban gateway markets. For a detailed discussion of our share of NOI, including the reasons management believes the metric is useful to investors and a reconciliation to the most comparable GAAP measure, see page 39.

The overall occupancy of our in-service office and retail properties was 87.0% at September 30, 2024, a decrease of 10 basis points from June 30, 2024. We define occupancy as space with signed leases for which revenue recognition has commenced in accordance with GAAP. Including vacant space for which we have signed leases that have not yet commenced revenue recognition in accordance with GAAP, our in-service office and retail properties were approximately 89.1% leased at September 30, 2024.

Investment Activity

We remain in active pursuit of opportunities in our core markets and asset types with primarily two types of counterparties: lenders to highly leveraged assets that require recapitalization and institutional owners seeking to diversify from the office asset class. To date, there has been limited market transaction activity for higher-quality office assets, though owners are increasingly testing the market to understand pricing. With lenders, there are fewer premier workplaces that are struggling with leverage, and in the few cases involving premier workplaces, lenders are generally electing to extend loans to borrowers who agree to invest modestly in their assets. Institutional owners are less interested in selling their higher quality assets, and there remains a material bid-ask spread given that, in most cases, assets have not been marked down to market-clearing levels. Notwithstanding these current challenges, we expect that transactions and our investment activity will increase in the coming quarters given the volume of maturing financings and continued mark downs in institutional portfolios. Our pipeline of potential opportunities is growing, including property and note acquisitions, sites with near term preleasing potential and new residential developments. No agreements are imminent, but we are encouraged by the activity. We also have interest from institutional investors in co-investing with us for select opportunities.

As of September 30, 2024, our development/redevelopment pipeline consisted of nine properties that, when completed, we expect will total approximately 2.7 million net rentable square feet. Our share of the estimated total cost for these projects is approximately $2.2 billion, of which approximately $1.1 billion remains to be invested. The commercial space in the pipeline, which excludes the residential projects, was 54% pre-leased as of October 31, 2024.

In the third quarter of 2024, we completed and fully placed in-service 180 CityPoint, an approximately 329,000 square foot laboratory/life sciences project located in Waltham, Massachusetts. BXP also partially placed in-service Skymark, a luxury residential property in Reston, Virginia that consists of 508 residential units across a five-story low-rise building and an iconic 39-story tower, which is one of the tallest buildings in Northern Virginia. The residential property is owned by a joint venture in which BXP has a 20% ownership interest.

As we continue to focus on new investments to drive future growth, we regularly review our portfolio to identify properties as potential sales candidates that either no longer fit within our portfolio strategy or could attract premium pricing in the current market. In addition, the BXP regional teams are pursuing alternative uses for some of our suburban land holdings, which includes vacant office buildings for which the highest and best use may not be office.

We are currently in active negotiations for the disposition of three land positions which, if successful, would generate approximately $70.0 million of proceeds in 2025. However, there can be no assurance that we will complete any of these transactions on the terms currently contemplated or at all.

A brief overview of each of our markets follows.

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 generally accepted accounting principles (“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, 2023 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, 2023.

Results of Operations for the Nine Months Ended September 30, 2024 and 2023

Net income attributable to BXP, Inc. and net income attributable to Boston Properties Limited Partnership increased by approximately $172.8 million and $192.6 million, respectively, for the nine months ended September 30, 2024 compared to 2023, as set forth in the following tables and for the reasons discussed below under the heading “Comparison of the nine months ended September 30, 2024 to the nine months ended September 30, 2023” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The following are reconciliations of Net Income Attributable to BXP, Inc. to Net Operating Income and Net Income Attributable to Boston Properties Limited Partnership to Net Operating Income for the nine months ended September 30, 2024 and 2023. For a detailed discussion of Net Operating Income (“NOI”), including the reasons management believes NOI is useful to investors, see page 61.

At September 30, 2024 and 2023, we owned or had joint venture interests in a portfolio of 184 and 190 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 nine months ended September 30, 2024 and 2023 show 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 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 attributable to BXP, Inc. and net income attributable to Boston Properties Limited Partnership, as applicable, the most directly comparable GAAP financial measures, plus (1) net income attributable to noncontrolling interests, interest expense, impairment loss, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) unrealized gain on non-real estate investment, 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 attributable to BXP, Inc. and net income 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 attributable to BXP, Inc. and net income attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. NOI should not be considered as a substitute for net income attributable to BXP, Inc. or net income 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.

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 when those properties are sold. For additional information see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

Comparison of the nine months ended September 30, 2024 to the nine months ended September 30, 2023

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 127 properties totaling approximately 40.3 million net rentable square feet, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or placed in-service on or prior to January 1, 2023 and owned and in service through September 30, 2024. The Total Property Portfolio includes the effects of the other properties either acquired, placed in-service, in or held for development or redevelopment after January 1, 2023 or disposed of on or prior to September 30, 2024. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the nine months ended September 30, 2024 and 2023 with respect to the properties that were acquired, placed in-service, in or held for development or redevelopment or sold. We did not sell any properties during the nine months ended September 30, 2024 and 2023.

(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 provides investors with information regarding our performance that is not immediately apparent from the comparable non-GAAP measures and allows investors to compare operating performance between periods.

(2)For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 61. Residential Net Operating Income for the nine months ended September 30, 2024 and 2023 is comprised of Residential Revenue of $37,027 and $35,768 less Residential Expenses of $17,413 and $16,984, respectively. Hotel Net Operating Income for the nine months ended September 30, 2024 and 2023 is comprised of Hotel Revenue of $38,080 and $35,554 less Hotel Expenses of $25,687 and $23,852, respectively, per the Consolidated Statements of Operations.

Same Property Portfolio

Lease Revenue (Excluding Termination Income)

Lease revenue (excluding termination income) from the Same Property Portfolio decreased by approximately $24.1 million for the nine months ended September 30, 2024 compared to 2023. The decrease was a result of our average occupancy decreasing from 90.9% to 89.0%, resulting in a decrease of approximately $45.8 million, partially offset by revenue per square foot increasing by approximately $0.82, contributing approximately $21.7 million.

Termination Income

Termination income increased by approximately $5.8 million for the nine months ended September 30, 2024 compared to 2023.

Termination income for the nine months ended September 30, 2024 related to 24 clients across the Same Property Portfolio and totaled approximately $8.4 million, which was primarily related to a retail client that terminated its lease early in Boston.

Termination income for the nine months ended September 30, 2023 related to 22 clients across the Same Property Portfolio and totaled approximately $2.6 million, which was primarily related to clients that terminated leases early in Seattle and Washington, DC.

Parking and other revenue increased by approximately $12.9 million for the nine months ended September 30, 2024 compared to 2023. Parking and other revenue increased by approximately $1.0 million and $11.9 million, respectively. The increase in other revenue primarily related to the View Boston observatory.

Real Estate Operating Expenses

Real estate operating expenses from the Same Property Portfolio increased by approximately $45.3 million, or 5.4%, for the nine months ended September 30, 2024 compared to 2023, due primarily to increases in (1) repairs and maintenance of approximately $15.1 million, or 11.0%, (2) utilities fluctuation of approximately $8.7 million, or 10.1%, and (3) increases in other real estate operating expenses of approximately $12.6 million, or 2.0%. The increase in repairs and maintenance related primarily to properties in our Boston region. The increase in utilities related primarily to properties in our New York City region.

(4)Lexington Office Park, 1050 and 1100 Winter Street, 17 Hartwell Avenue, Kingstowne One and a portion of Shady Grove Innovation District are no longer considered “in-service” because each property’s occupied percentage is less than 50% and we are no longer actively leasing the properties in anticipation of a future development/redevelopment. The properties will be considered held for development or redevelopment until the last client has vacated the property and the property is no longer revenue producing. This portion of Shady Grove Innovation District is comprised of three buildings, 2092 and 2098 Gaither Road and 15825 Shady Grove Road that were taken out of service between January 1, 2023 and September 30, 2024.

(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.

(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.

(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.

Other Operating Revenue and Expense Items

Development and Management Services Revenue

Development and management services revenue decreased by approximately $8.8 million for the nine months ended September 30, 2024 compared to 2023. Development services revenue and management services revenue decreased by approximately $4.6 million and $4.2 million, respectively. The decrease in development services revenue is primarily related to decreases in fees associated with tenant improvement projects in Boston and New York City and decreases in development income earned from unconsolidated joint ventures in the San Francisco region. The decrease in management services revenue primarily related to the elimination of property and asset management fees earned from an unconsolidated joint venture in the Los Angeles region in which we acquired the joint venture partner’s interest in December 2023.

General and Administrative Expense

General and administrative expense decreased by approximately $3.9 million for the nine months ended September 30, 2024 compared to 2023 primarily due to decreases in compensation expense and other general and administrative expenses of approximately $3.2 million and $0.7 million, respectively. The decrease in compensation expense related to an approximately $5.7 million decrease in other compensation expenses, partially offset by an approximately $2.5 million increase in the value of our deferred compensation plan.

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, 2024 and 2023 were approximately $13.2 million and $13.5 million, respectively. These costs are not included in the general and administrative expenses discussed above.

Transaction Costs

Transaction costs decreased by approximately $1.1 million for the nine months ended September 30, 2024 compared to 2023. In general, transaction costs relating to the formation of new joint ventures and the pursuit of other transactions are expensed as incurred.

Depreciation and Amortization Expense

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 OP Unit redemptions by BPLP.  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. For additional information see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

As a result, during the nine months ended September 30, 2023, BPLP recorded approximately $0.6 million of accelerated depreciation expense for the demolition of the garage.

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.

Other Income and Expense Items

Income (Loss) from Unconsolidated Joint Ventures

For the nine months ended September 30, 2024 compared to 2023, income (loss) from unconsolidated joint ventures increased by approximately $268.2 million primarily due to the recognition of non-cash impairment charges related to our investments in 360 Park Avenue South, 200 Fifth Avenue, Platform 16, and Safeco Plaza aggregating approximately $272.6 million during the nine months ended September 30, 2023, partially offset by an approximately $35.8 million gain on investment related to our Metropolitan Square joint venture interest. Neither of these items recurred during the nine months ended September 30, 2024.

Gains on Sales of Real Estate

The $0.5 million gains on sale of real estate for the nine months ended September 30, 2024 and 2023 were related to the sale of real estate occurring in prior periods.

Gains on sales of real estate 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 OP Unit redemptions by BPLP. 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 the gains on sales of real estate when those properties are sold. For additional information, see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

Interest and Other Income (Loss)

Interest and other income (loss) decreased by approximately $9.3 million for the nine months ended September 30, 2024 compared to 2023, due primarily to a decrease in our outstanding cash balances.

Gains from Investments in Securities

Gains from investments in securities for the nine months ended September 30, 2024 and 2023 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 the deferred compensation plans, each officer or non-employee director who is eligible to participate is permitted to defer a portion of the officer’s current income or the non-employee director’s compensation on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer or non-employee director. 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 BXP’s officers or former non-employee directors 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, 2024 and 2023, we recognized gains of approximately $4.8 million and $2.3 million, respectively, on these investments. By comparison, our general and administrative expense decreased by approximately $4.8 million and $2.3 million during the nine months ended September 30, 2024 and 2023, 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 officers and former non-employee directors of BXP participating in the plans.

Unrealized Gain on Non-Real Estate Investment

We invest in non-real estate investments, which are primarily environmentally-focused investment funds. As a result, during the nine months ended September 30, 2024 and 2023, we recognized an unrealized gain of approximately $0.5 million and $0.3 million, respectively, due to the observable changes in the fair value of the investments.

Impairment Loss

At March 31, 2024, we evaluated the expected hold period for a portion of our Shady Grove property, located in Rockville, Maryland, consisting of 2 Choke Cherry Road, 2094 Gaither Road and a land parcel. Based on a shorter-than-expected hold period, we reduced the carrying value of a portion of the property that we anticipate selling to a third-party developer to its estimated fair value at March 31, 2024. As a result, each of BXP and BPLP recognized an impairment loss of approximately $13.6 million. Our estimated fair value was based on Level 3 inputs as defined in Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures” and on a pending offer from a third party (See Note 3 to the Consolidated Financial Statements).

(1)Consists of the mortgage loan and, if applicable, fair value debt and swap adjustments collateralized by (1) 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties located in Cambridge, Massachusetts, (2) Santa Monica Business Park located in Santa Monica, California and (3) 901 New York Avenue in Washington, DC (See Note 6 to the Consolidated Financial Statements).

(2)On April 17, 2024, BPLP established an unsecured commercial paper program (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, 2024 and 2023 was approximately $31.3 million and $30.8 million, respectively. These costs are not included in the interest expense referenced above. The decrease in capitalized interest is primarily attributable to a development project that had a finance lease and is now placed in service.

At September 30, 2024, our variable rate debt consisted of (1) BPLP’s $2.0 billion 2021 Credit Facility, (2) BPLP’s $700.0 million 2023 Unsecured Term Loan and (3) BPLP’s $500.0 million unsecured commercial paper notes. As of September 30, 2024, the 2021 Credit Facility did not have a balance outstanding. 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 our 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties that bore 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 a summary of our consolidated debt as of September 30, 2024 refer to the heading “Liquidity and Capital Resources—Debt Financing” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Noncontrolling Interest—Common Units of the Operating Partnership

For BXP, noncontrolling interest—common units of the Operating Partnership increased by approximately $20.0 million for the nine months ended September 30, 2024 compared to 2023 due primarily to an increase in allocable income, which was primarily the result of recognizing a non-cash impairment charge related to our investment in unconsolidated joint ventures during the nine months ended September 30, 2023 that did not recur during the nine months ended September 30, 2024. 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, 2024 and 2023

Net income (loss) attributable to BXP, Inc. and net income (loss) attributable to Boston Properties Limited Partnership increased approximately $195.5 million and $217.6 million, respectively, for the three months ended September 30, 2024 compared to 2023, as detailed in the following tables and for the reasons discussed below under the heading “Comparison of the three months ended September 30, 2024 to the three months ended September 30, 2023” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The following are reconciliations of Net Income (Loss) Attributable to BXP, Inc. to Net Operating Income and Net Income (Loss) Attributable to Boston Properties Limited Partnership to Net Operating Income for the three months ended September 30, 2024 and 2023.

At September 30, 2024 and 2023, we owned or had joint venture interests in a portfolio of 184 and 190 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 months ended September 30, 2024 and 2023 show 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 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 unconsolidated joint ventures, 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 investment, gains (losses) from investments in securities, interest and other income (loss), gains on sales of real estate, 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.

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 when those properties are sold. For additional information see the Explanatory Note that follows the cover page of this Quarterly Report on Form 10-Q.

Comparison of the three months ended September 30, 2024 to the three months ended September 30, 2023

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 128 properties totaling approximately 40.8 million net rentable square feet, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or placed in-service on or prior to July 1, 2023 and owned and in-service through September 30, 2024. The Total Property Portfolio includes the effects of the other properties either acquired, placed in-service, in or held for development or redevelopment after July 1, 2023 or disposed of on or prior to September 30, 2024. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the three months ended September 30, 2024 and 2023 with respect to the properties that were acquired, placed in-service, in or held for development or redevelopment or sold. We did not sell any properties during the three months ended September 30, 2024 and 2023.

Same Property Portfolio

Lease Revenue (Excluding Termination Income)

Lease revenue (excluding termination income) from the Same Property Portfolio decreased by approximately $7.6 million for the three months ended September 30, 2024 compared to 2023. The decrease was a result of our average occupancy decreasing from 90.6% to 88.2%, resulting in a decrease of approximately $20.0 million, partially offset by our average revenue per square foot increasing by approximately $1.54, contributing approximately $12.4 million.

Termination Income

Termination income increased by approximately $3.1 million for the three months ended September 30, 2024 compared to 2023.

Termination income for the three months ended September 30, 2024 related to eight clients across the Same Property Portfolio and totaled approximately $5.7 million, which was primarily related to a retail client that terminated its lease early in Boston.

Termination income for the three months ended September 30, 2023 related to 10 clients across the Same Property Portfolio and totaled approximately $2.6 million, which was primarily related to clients that terminated leases early in Seattle and Washington, DC.

Parking and Other Revenue

Parking and other revenue increased by approximately $1.8 million for the three months ended September 30, 2024 compared to 2023.

Real Estate Operating Expenses

Real estate operating expenses from the Same Property Portfolio increased by approximately $15.3 million, or 5.3%, for the three months ended September 30, 2024 compared to 2023, due primarily to increases in (1)utilities of approximately $4.3 million, or 13.9%, (2) repairs and maintenance of approximately $4.3 million, or 9.2%, and (3) other real estate operating expenses of approximately $4.1 million, or 1.9%. The increase in utilities related primarily to properties in our New York City region. The increase in repairs and maintenance related primarily to properties in our Boston region. In addition, there was an approximately $2.6 million increase related to the marketing and operating expenses associated with the View Boston observatory.

(1)On November 30, 2023, we elected to suspend redevelopment. Although no longer in redevelopment, this property is not considered “in-service” as we are not actively leasing this property in anticipation of restarting redevelopment in the future.

(2)Lexington Office Park, 1050 and 1100 Winter Street, 17 Hartwell Avenue, Kingstowne One and a portion of Shady Grove Innovation District are no longer considered “in-service” because each property’s occupied percentage is less than 50% and we are no longer actively leasing the property in anticipation of a future development/redevelopment. The properties will be considered held for development or redevelopment until the last client has vacated the property and the property is no longer revenue producing. This portion of Shady Grove Innovation District is comprised of three buildings, 2092 and 2098 Gaither Road and 15825 Shady Grove Road.

(3)1100 Winter Street was taken out of service as of September 30, 2024. Rental revenue at 1100 Winter Street for the three months ended September 30, 2024 includes approximately $6.4 million of termination income.

Residential Net Operating Income

Net operating income for our residential same properties increased by approximately $78,000 for the three months ended September 30, 2024 compared to 2023.

_______________  

(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.

(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.

(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 $5.2 million for the three months ended September 30, 2024, representing an increase of approximately $0.8 million compared to the three months ended September 30, 2023.

Other Operating Revenue and Expense Items

Development and Management Services Revenue

Development and management services revenue decreased by approximately $2.5 million for the three months ended September 30, 2024 compared to 2023. Development services revenue and management services revenue decreased by approximately $1.5 million and $1.0 million, respectively. The decrease in development services revenue was primarily related to a decrease in development income earned from unconsolidated joint ventures in the San Francisco and Washington D.C. regions. The decrease in management services revenue was primarily related to the elimination of property and asset management fees earned from an unconsolidated joint venture in the Los Angeles region which we acquired the joint venture partner’s interest in December 2023.

General and Administrative Expense

General and administrative expense increased by approximately $1.9 million for the three months ended September 30, 2024 compared to 2023 primarily due to an increase in compensation expense of approximately $2.6 million, partially offset by an approximately $0.7 million decrease in other general and administrative expenses. The increase in compensation expense related to an approximately $3.1 million increase in the value of our deferred compensation plan partially offset by an approximately $0.5 million decrease in other compensation expenses.

Table of Contents

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 the three months ended September 30, 2024 and 2023 were approximately $4.2 million and $4.4 million, respectively. These costs are not included in the general and administrative expenses discussed above.

Transaction Costs

Transaction costs decreased by approximately $0.6 million for the three months ended September 30, 2024 compared to 2023. In general, transaction costs relating to the formation of new joint ventures and the pursuit of other transactions are expensed as incurred.

Depreciation and Amortization Expense

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 OP Unit redemptions by BPLP.  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. For additional information see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

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.

Other Income and Expense Items

Loss from Unconsolidated Joint Ventures

For the three months ended September 30, 2024 compared to 2023, loss from unconsolidated joint ventures decreased by approximately $240.5 million primarily due to the recognition of non-cash impairment charges related to our investments in 360 Park Avenue South, 200 Fifth Avenue, Platform 16, and Safeco Plaza aggregating approximately $272.6 million during the three months ended September 30, 2023, partially offset by an approximately $35.8 million gain on investment related to our Metropolitan Square joint venture interest. Neither of these items recurred during the three months ended September 30, 2024.

Gains on Sales of Real Estate

The $0.5 million gains on sale of real estate for the three months ended September 30, 2024 and 2023 were related to the sale of real estate occurring in prior periods.

Gains on sales of real estate 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 OP Unit redemptions by BPLP. 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 the gains on sales of real estate when those properties are sold. For additional information, see the Explanatory Note that immediately follows the cover page of this Quarterly Report on Form 10-Q.

Interest and Other Income (Loss)

Interest and other income (loss) decreased by approximately $6.3 million for the three months ended September 30, 2024 compared to 2023, due primarily to a decrease in our outstanding cash balances.

Gains (Losses) from Investments in Securities

Gain (losses) from investments in securities for the three months ended September 30, 2024 and 2023 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 the deferred compensation plans, each officer or non-employee director who is eligible to participate is permitted to defer a portion of the officer’s current income or the non-employee director’s compensation on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer or non-employee director. 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 BXP’s officers or former non-employee directors under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains (losses) from investments in securities. During the three months ended September 30, 2024 and 2023, we recognized gains (losses) of approximately $2.2 million and $(0.9) million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $2.2 million and $(0.9) million during the three months ended September 30, 2024 and 2023, respectively, as a result of increases (decreases) in our liability under our deferred compensation plans that was associated with the performance of the specific investments selected by officers and former non-employee directors of BXP participating in the plans.

Unrealized Gain (Loss) on Non-Real Estate Investment

We invest in non-real estate investments, which are primarily environmentally-focused investment funds. As a result, during the three months ended September 30, 2024 and 2023, we recognized an unrealized gain (loss) of approximately $0.1 million and $(0.1) million, respectively, due to the observable changes in the fair value of the investments.

(1)Consists of the mortgage loan and, if applicable, fair value debt and swap adjustments collateralized by (1) 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties located in Cambridge, Massachusetts, (2) Santa Monica Business Park located in Santa Monica, California and (3) 901 New York Avenue in Washington, DC (See Note 6 to the Consolidated Financial Statements).

(2)On April 17, 2024, BPLP established an unsecured commercial paper program (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, 2024 and 2023 was approximately $11.6 million and $9.7 million, respectively. These costs are not included in the interest expense referenced above.

At September 30, 2024, our variable rate debt consisted of (1) BPLP’s $2.0 billion 2021 Credit Facility, (2) BPLP’s $700.0 million 2023 Unsecured Term Loan and (3) BPLP’s $500.0 million unsecured commercial paper notes. As of September 30, 2024, the 2021 Credit Facility did not have a balance outstanding. 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 our 325 Main Street, 355 Main Street, 90 Broadway and Cambridge East Garage (also known as Kendall Center Green Garage) properties that bore 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.

Noncontrolling Interest—Common Units of the Operating Partnership

For BXP, noncontrolling interest—common units of the Operating Partnership increased by approximately $22.2 million for the three months ended September 30, 2024 compared to 2023 due primarily to an increase in allocable income, which was primarily the result of recognizing a non-cash impairment charge related our investment in unconsolidated joint ventures during the three months ended September 30, 2023 that did not recur during the three months ended September 30, 2024. 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:

•fund normal recurring expenses;

•meet debt service and principal repayment obligations and balloon payments on maturing debt, including:

◦$850.0 million of 3.200% unsecured senior notes due January 15, 2025,

◦$700.0 million of principal outstanding on the 2023 Unsecured Term Loan due May 16, 2025,

◦$100.0 million of principal outstanding on the 2024 Unsecured Term Loan due September 26, 2025, for which we have three, one-year extension options, subject to customary conditions,

◦$203.6 million of mortgage debt secured by our 901 New York Avenue property due January 5, 2025, for which we have the right to extend the maturity date for a period of five years, subject to certain customary conditions, and

◦amounts that become due under BPLP’s unsecured commercial paper program;

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

•fund development and redevelopment costs;

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

Table of Contents

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

•make the minimum distribution required to enable BXP to maintain its REIT qualification under the Internal Revenue Code of 1986, as amended.

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

•cash flow from operations;

•distribution of cash flows from joint ventures;

•cash and cash equivalent balances;

•borrowings under BPLP’s 2021 Credit Facility, unsecured term loans, short-term bridge facilities and construction loans;

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

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

•private equity sources, including institutional investors; and

•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 expect to fund our current development/redevelopment projects primarily with our available cash balances, funding from institutional private equity partners, construction loans, unsecured term loans, and proceeds from possible asset sales, BPLP’s 2021 Credit Facility and BPLP's commercial paper program. We use BPLP’s 2021 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 2021 Credit Facility to backstop BPLP’s 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 owned by a joint venture, the extent of pre-leasing, our available cash and access to cost effective capital at the given time.

Table of Contents

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 sources of capital will continue to provide the funds necessary for our short-term liquidity needs. Material adverse changes in one or more sources of capital may adversely affect our net cash flows.

As of September 30, 2024, we had nine properties under development or redevelopment. BXP’s Share of the estimated total investment for these projects is approximately $2.2 billion, of which approximately $1.1 billion remains to be funded through 2029.

Since the second quarter of 2024, we further strengthened our balance sheet by sourcing additional liquidity. Notable transactions include:

•On August 26, 2024, BPLP completed a public offering of $850.0 million in aggregate principal amount of its 5.750% unsecured senior notes due 2035. The notes were priced at 99.961% of the principal amount to yield an effective rate (including financing fees) of approximately 5.842% per annum to maturity. The notes will mature on January 15, 2035, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $841.9 million after deducting underwriting discounts and transaction expenses. We intend to use the net proceeds to repay the $850.0 million of 3.200% unsecured senior notes due January 15, 2025.

•On September 27, 2024, BPLP entered into the 2024 Unsecured Term Loan that provides for a $100.0 million unsecured term loan facility with the Lender under the SMBP Loan. The 2024 Unsecured Term Loan bears interest at a variable rate, matures on September 26, 2025 and has three, one-year extension options, subject to customary conditions. The interest rate is subject to an existing interest rate swap to fix Daily Simple SOFR at a fixed interest rate of approximately 2.688% per annum for a period that ends on April 1, 2025 (See Notes 6 and 7 to the Consolidated Financial Statements). Upon entry into the credit agreement, BPLP exercised its option to draw $100.0 million under the 2024 Unsecured Term Loan. The proceeds were used to repay the portion of the SMBP Loan held by the Lender. After the repayment, the SMBP Loan had a remaining principal balance of $200.0 million.

•On October 8, 2024, we modified the SMBP Loan. The SMBP Loan had an outstanding principal balance of $200.0 million, bore interest at a variable rate equal to Daily Simple SOFR + 1.38% per annum and was scheduled to mature on July 19, 2025. The modified loan is scheduled to mature on October 8, 2028 and continues to bear interest at a variable rate equal to Daily Simple SOFR + 1.38% per annum until July 19, 2025. Beginning July 19, 2025, the mortgage loan will bear interest at Daily Simple SOFR + 1.60% per annum through the maturity date. The entire principal is subject to interest rate swap contracts to fix Daily Simple SOFR at a weighted-average fixed interest rate of approximately 2.675% per annum through April 1, 2025 (See Note 7 to the Consolidated Financial Statements).

As of September 30, 2024, our share of unconsolidated joint venture debt maturing through November 2025 was approximately $588.7 million. The foregoing debt matures at different times through November 2025 and, to the extent not refinanced, we expect to fund the repayment of this debt using available cash balances, proceeds from asset sales, draws on BPLP’s 2021 Credit Facility, proceeds from BPLP’s unsecured commercial paper program, secured debt or unsecured debt, or both. We expect our interest expense will be flat or slightly less in 2025 compared to 2024 primarily due to expiring below market debt related to acquisitions in late 2023 and early 2024, lower average outstanding debt balances and the impact of anticipated lower short-term rates.

As of October 31, 2024, we had available cash of approximately $1.2 billion (of which approximately $121.2 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 $2.0 billion available under BPLP’s 2021 Credit Facility, of which $500.0 million is being used to backstop the unsecured commercial paper program, and our available cash, as of October 31, 2024, are sufficient to fund our remaining capital needs on existing development and redevelopment projects, fund acquisitions, repay our maturing indebtedness when due (if not refinanced or extended), satisfy our REIT distribution requirements and still allow us to act opportunistically on attractive investment opportunities. We are currently in active negotiations for the disposition of three land positions which, if successful, would generate approximately $70.0 million of proceeds in

2025. However, there can be no assurance that we will complete any of these transactions on the terms currently contemplated or at all.

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, and depending on the sources of liquidity, higher interest expense or share count.

We have not sold any shares under BXP’s $600.0 million “at the market” equity offering program.

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. Common and LTIP unitholders (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.

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.

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 attractive 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 $1.5 billion and $0.9 billion at September 30, 2024 and 2023, respectively, representing an increase of approximately $0.5 billion. The following table sets forth changes in cash flows:

			Nine months ended September 30,
			2024						2023						Change
			(in thousands)
Net cash provided by operating activities			$	850,755					$	914,372					$	(63,617)
Net cash used in investing activities			(850,787)						(875,578)						24,791
Net cash (used in) provided by financing activities			(141,051)						154,782						(295,833)

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 7.6 years as of September 30, 2024, with occupancy rates historically in the range of 87% to 92%.

Table of Contents

Generally, our properties generate a relatively consistent stream of cash flow 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. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings to enhance or maintain our market position. Cash used in investing activities for the nine months ended September 30, 2024 and September 30, 2023 is detailed below:

			Nine months ended September 30,
			2024						2023
			(in thousands)
Construction in progress (1)			$	(469,948)					$	(361,625)

Investments in securities, net			1,025						1,779
Net cash used in investing activities			$	(850,787)					$	(875,578)

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

(1)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 (See Note 14 to the Consolidated Financial Statements). In addition, we incurred costs associated with our continued development/redevelopment of Reston Next Office Phase II that was partially placed in-service, 290 Binney Street, 300 Binney Street and 121 Broadway.

Construction in progress for the nine months ended September 30, 2023 included ongoing expenditures associated with 2100 Pennsylvania Avenue, 140 Kendrick Street Building A and the View Boston observatory at The Prudential Center, which were fully placed in-service during the nine months ended September 30, 2023 and 180 CityPoint that was partially placed in-service during the nine months ended September 30, 2023. In addition, we incurred costs associated with our continued development/redevelopment of 103 CityPoint, Reston Next Office Phase II, 760 Boylston Street, 105 Carnegie Center, 290 Binney Street and 300 Binney Street.

(2)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.

(3)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.

Capital contributions to unconsolidated joint ventures for the nine months ended September 30, 2023 consisted primarily of cash contributions of approximately $46.8 million, $32.8 million, $17.5 million, $14.4 million and $9.5 million to our Gateway Commons, Platform 16, Worldgate Drive, Dock 72 and 751 Gateway joint ventures, respectively. On January 31, 2023, we entered into a new joint venture for 13100 and 13150 Worldgate Drive located in Herndon, Virginia.

(4)Capital distributions from unconsolidated joint ventures for the nine months ended September 30, 2023 consisted primarily of a cash distribution totaling approximately $7.4 million from our 360 Park Avenue South joint venture.

(5)On June 5, 2023, a joint venture in which we own a 30% interest repaid the existing construction loan collateralized by its 500 North Capitol Street, NW property and obtained new mortgage loans with related parties. At the time of the payoff, the outstanding balance of the loan totaled approximately $105.0 million and was scheduled to mature on June 6, 2023. The new mortgage loans have an aggregate principal balance of $105.0 million, bear interest at a weighted average fixed rate of 6.83% per annum and mature on June 5, 2026. Our portion of the mortgage loans, $10.5 million, has been reflected as a Related Party Note Receivable on our Consolidated Balance Sheets. 500 North Capitol Street, NW is an approximately 231,000 square foot premier workplace in Washington, DC.

Cash used in financing activities for the nine months ended September 30, 2024 totaled approximately $141.1 million. This amount consisted primarily of the repayment of BPLP’s $700 million in aggregate principal amount of its 3.800% unsecured senior notes due February 1, 2024 and payment of our regular dividends and distributions to our shareholders and unitholders and distributions to noncontrolling interests in property partnerships, partially offset by the issuance of BPLP’s $850 million in aggregate principal amount of its 5.750% unsecured senior notes due 2035 and contributions from noncontrolling interests in property partnerships including approximately $97.2 million from the sale of a 45% interest in 290 Binney Street in Cambridge, Massachusetts. Future debt payments are discussed below under the heading “Debt Financing.”

Table of Contents

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:

(1)     our consolidated debt; plus

(2)     the product of (x) the closing price per share of BXP common stock on September 30, 2024, as reported by the New York Stock Exchange, multiplied by (y) the sum of:

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

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

(iii)     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

(iv)     the number of OP Units issuable upon conversion of 2012 OPP Units, and 2013 - 2021 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, 2022 - 2024 MYLTIP Units are not included in this calculation as of September 30, 2024.

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.

Debt Financing

As of September 30, 2024, we had approximately $16.2 billion of outstanding consolidated indebtedness, representing approximately 53.35% of our Consolidated Market Capitalization as calculated above consisting of approximately (1) $10.6 billion (net of discount and deferred financing fees) in publicly traded unsecured senior notes having a GAAP weighted-average interest rate of 4.07% per annum and maturities in 2025 through 2035, (2) $4.3 billion (net of deferred financing fees and fair value interest adjustments) of property-specific mortgage debt having a GAAP weighted-average interest rate of 4.16% per annum and a weighted-average term of 3.7 years, (3) $0.8 billion (net of deferred financing fees and fair value interest adjustments) of unsecured term loans having a GAAP weighted-average interest rate of 6.45% per annum with maturities in 2025, and (4) $0.5 billion of unsecured commercial paper borrowings having a weighted-average interest rate of 5.22% per annum and a weighted-average maturity of 34 days, from the issuance date.

The table below summarizes the aggregate carrying value of our outstanding indebtedness, as well as Consolidated Debt Financing Statistics at September 30, 2024 and September 30, 2023.

We entered into interest rate swap contracts that effectively fixed the variability of these loans for all or a portion of the applicable debt term and as such, they are reflected in our Fixed rate statistics. At September 30, 2023, BPLP’s 2023 Unsecured Term Loan bore interest at a variable rate which was subject to interest rate swaps that effectively fixed the interest rate for a portion of the applicable debt term, and as such, the 2023 Unsecured Term Loan is reflected in our Fixed rate statistics.

Unsecured Credit Facility

The 2021 Credit Facility provides for borrowings of up to $2.0 billion, as described below, through BPLP’s revolving facility, subject to customary conditions. The 2021 Credit Facility matures on June 15, 2026 and includes a sustainability-linked pricing component. Under the 2021 Credit Facility, BPLP had the option to increase the original total commitment of $1.5 billion by up to an additional $500.0 million by increasing the amount of the revolving facility and/or by incurring one or more term loans, in each case, subject to syndication of the increase and other conditions (the “Accordion Option”). On September 28, 2023, BPLP exercised a portion of the Accordion Option, which increased the then maximum borrowing amount under the 2021 Credit Facility from $1.5 billion to $1.815 billion. On April 29, 2024, BPLP exercised the remainder of the Accordion Option and further increased the maximum borrowing amount under the 2021 Credit Facility to $2.0 billion. All other terms of the 2021 Credit Facility remain unchanged.

At BPLP’s option, loans under the 2021 Credit Facility will bear interest at a rate per annum equal to (1) (a) in the case of loans denominated in Dollars, Term SOFR and SOFR, (b) in the case of loans denominated in Euro, EURIBOR, (c) in the case of loans denominated in Canadian Dollars, Term CORRA, and (d) in the case of loans denominated in Sterling, SONIA, in each case, plus a margin ranging from 70.0 to 140.0 basis points based on BPLP’s credit rating or (2) an alternate base rate equal to the greatest of (a) the Federal Funds rate plus 0.5%, (b) the administrative agent’s prime rate, (c) Term SOFR plus 1.00%, and (d) 1.00%, in each case, plus a margin ranging from 0 to 40 basis points based on BPLP’s credit rating. In addition, there is a SOFR credit spread adjustment of 0.10%.

Based on BPLP’s September 30, 2024 credit rating, (1) the applicable Daily SOFR, Term SOFR, alternative currency daily rate, and alternative currency term rate margins are 0.850%, (2) the alternate base rate margin is zero basis points and (3) the facility fee is 0.20% per annum.

The 2021 Credit Facility is used as a backstop for BPLP’s $500.0 million unsecured commercial paper program (See “Unsecured Commercial Paper” below). As such, BPLP intends to maintain, at a minimum, availability under the 2021 Credit Facility in an amount equal to the amount of unsecured commercial paper notes outstanding.

At September 30, 2024 and October 31, 2024, BPLP had no borrowings under its 2021 Credit Facility, outstanding letters of credit totaling approximately $6.1 million, and $500.0 million is being used as a backstop for the commercial paper program. Therefore, at September 30, 2024 and October 31, 2024, BPLP has the ability to borrow approximately $1.5 billion.

Unsecured Term Loans

The 2023 Unsecured Term Loan provided for a single borrowing of up to $1.2 billion. Upon entry into the credit agreement in January 2023, BPLP exercised its option to draw $1.2 billion under the 2023 Unsecured Term Loan. Under the credit agreement governing the 2023 Unsecured Term Loan, BPLP may, at any time prior to the maturity date, increase total commitments by up to an additional $300.0 million in aggregate principal amount by increasing the existing 2023 Unsecured Term Loan or incurring one or more additional term loans, in each case, subject to syndication of the increase and other conditions. On April 29, 2024, BPLP repaid $500.0 million of the outstanding balance under the 2023 Unsecured Term Loan from the proceeds of its unsecured commercial paper program (See “Unsecured Commercial Paper” below). The 2023 Unsecured Term Loan had an initial maturity date of May 16, 2024, with one 12-month extension option, subject to customary conditions. On May 16, 2024, BPLP exercised its option to extend the maturity date of the 2023 Unsecured Term Loan to May 16, 2025. All other terms of the 2023 Unsecured Term Loan remain unchanged.

At BPLP’s option, loans under the 2023 Unsecured Term Loan will bear interest at a rate per annum equal to (1) a base rate equal to the greatest of (a) the Federal Funds rate plus 0.5%, (b) the administrative agent’s prime rate, (c) Term SOFR for a one-month period plus 1.00%, and (d) 1.00%, in each case, plus a margin ranging from 0 to 60 basis points based on BPLP’s credit rating; or (2) a rate equal to adjusted Term SOFR with a one-month period plus a margin ranging from 75 to 160 basis points based on BPLP’s credit rating.

On September 27, 2024, BPLP entered into the 2024 Unsecured Term Loan with the Lender under the SMBP Loan. Upon entry into the credit agreement, BPLP exercised its option to draw $100.0 million under the 2024 Unsecured Term Loan. The proceeds were used to repay the portion of the SMBP Loan held by the Lender. After the repayment, the SMBP Loan had a remaining principal balance of $200.0 million (See Note 14 to the Consolidated Financial Statements). The 2024 Unsecured Term Loan matures on September 26, 2025 with three,

one-year extension options, subject to customary conditions.

At BPLP’s option, loans under the 2024 Unsecured Term Loan will bear interest at a rate per annum equal to (1) a base rate equal to the highest of (a) zero, (b) Prime Rate, (c) the Federal Funds effective rate plus 0.50%, and (d) Term SOFR for a one-month period plus 1.10%, in each case, plus a margin ranging from 0 to 60 basis points based on BPLP’s credit rating; or (2) a rate equal to adjusted Term SOFR or Daily Simple SOFR with a one-month period plus a margin ranging from 75 to 160 basis points based on BPLP’s credit rating.

Based on BPLP’s September 30, 2024 credit rating, (1) the 2023 Unsecured Term Loan bears interest at a rate equal to Term SOFR plus 1.05% per annum and (2) the 2024 Unsecured Term Loan bears interest at a rate equal to Daily Simple SOFR plus1.05% per annum. The 2024 Unsecured Term Loan is subject to an existing interest rate swap to fix Daily Simple SOFR at a fixed rate of approximately 2.688% per annum for a period that ends on April 1, 2025 (See Note 7 to the Consolidated Financial Statements). At September 30, 2024 and October 31, 2024, BPLP had $700.0 million and $100.0 million of principal outstanding under the 2023 Unsecured Term Loan and 2024 Unsecured Term Loan, respectively.

For a description of BPLP’s outstanding unsecured senior notes as of September 30, 2024, See Note 6 to the Consolidated Financial Statements.

On February 1, 2024, BPLP repaid $700.0 million in aggregate principal amount of its 3.800% senior notes due February 1, 2024. The repayment was completed with available cash and the $600.0 million proceeds from the mortgage loan entered into on October 26, 2023. The repayment price was approximately $713.3 million, which was equal to the stated principal plus approximately $13.3 million of accrued and unpaid interest to, but not including, the repayment date. Excluding the accrued and unpaid interest, the repayment price was equal to the principal amount being repaid.

On August 26, 2024, BPLP completed a public offering of $850.0 million in aggregate principal amount of its 5.750% unsecured senior notes due 2035. The notes were priced at 99.961% of the principal amount to yield an effective rate (including financing fees) of approximately 5.842% per annum to maturity. The notes will mature on January 15, 2035, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $841.9 million after deducting underwriting discounts and transaction expenses.

Unsecured Commercial Paper

On April 17, 2024, BPLP established an unsecured commercial paper program. 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 $500.0 million with varying maturities of up to one year. Amounts available under the unsecured 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 unsecured commercial paper program is backstopped by available capacity under the 2021 Credit Facility. At September 30, 2024, BPLP had an aggregate of $500.0 million of unsecured commercial paper notes outstanding that bore interest at a weighted-average rate of approximately 5.22% per annum and had a weighted-average maturity of 34 days, from the issuance date. At October 31, 2024, BPLP had an aggregate of $500.0 million of commercial paper notes outstanding that bore interest at a weighted-average rate of approximately 5.03% per annum and had a weighted-average maturity of 29 days, from the issuance date. Proceeds from the unsecured commercial paper program were used to reduce BPLP’s 2023 Unsecured Term Loan to $700.0 million.

Mortgage Notes Payable

On January 8, 2024, we acquired our joint venture partner’s 50% economic ownership interest in the joint venture that owns 901 New York Avenue located in Washington, DC (See Note 3 to the Consolidated Financial Statements). The property is subject to existing mortgage indebtedness. At acquisition, the mortgage loan had an outstanding principal balance of approximately $207.1 million, bore interest at 3.61% per annum and was scheduled to mature on January 5, 2025. The mortgage loan was recorded at a fair value of approximately $198.7 million. On January 11, 2024, we modified the mortgage loan to provide for two extension options totaling five years of additional term, each subject to certain conditions. The first loan extension option provides for an additional term of four years at a fixed interest rate of 5.0% per annum.

_______________ 

(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 adjustments required under Accounting Standards Codification 805 “Business Combinations” to reflect loans and swaps at their fair values (if any).

(2)Carrying amount includes an approximately $2.2 million fair value interest adjustment. The loan includes two extension options, subject to certain conditions. The first loan extension option provides for an additional term of four years at a fixed interest rate of 5.0% per annum.

(3)The mortgage loan requires interest only payments with a balloon payment due at maturity.

(4)The mortgage loan bears interest at a variable rate of Daily Simple SOFR plus 1.38% per annum (See Notes 6 and 14 to the Consolidated Financial Statements). The borrower under the loan entered into interest rate swap contracts to fix Daily Simple SOFR at a weighted-average fixed interest rate of 2.675% for the period commencing on February 1, 2023 and ending on April 1, 2025. Stated interest rate reflects the weighted average fixed interest rate based on the interest rate swap contracts plus 1.38% per annum. Carrying amount includes an approximately $1.5 million fair value interest adjustment and excludes the adjustment required to reflect the interest rate swap at fair value upon acquisition of approximately $1.9 million.

(5)The mortgage loan bears interest at a variable rate of Daily Compounded SOFR plus 2.25% per annum. On December 7, 2023, 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.

(6)This property is owned by a consolidated entity in which we have a 60% interest. The partners’ share of the carrying amount has been adjusted for basis differentials.

(7)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, 2024, 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 (See Note 8 to the Consolidated Financial Statements).

(8)This property is owned by a consolidated entity in which we have a 55% interest.

Derivative Instruments and Hedging Activities

As of September 30, 2024, we had $900.0 million of interest rate swaps outstanding, where hedge accounting was elected, with a fair value of approximately $(10.2) million. 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 20% to approximately 71%. Fourteen 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, 2024, 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, 2024. 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. 

Insurance

For information concerning our insurance program, see Note 8 to the Consolidated Financial Statements.

Funds from Operations

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“Nareit”), we calculate Funds from Operations, or “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.

(1)During the three months ended September 30, 2023, we recognized an other-than-temporary impairment loss on our investments in Platform 16, 360 Park Avenue South, 200 Fifth Avenue and Safeco Plaza aggregating approximately $272.6 million.

(2)On September 13, 2023, a joint venture in which we owned a 20% equity interest completed the first step of a two-step restructuring of the ownership in Metropolitan Square, which resulted in, among other things, (i) the cessation of our obligation to fund future investments through our then 20% equity interest, which caused us to recognize a gain on investment of approximately $35.8 million related to our deficit investment balance, which was primarily due to excess distributions, and (ii) the removal of the property from our in-service portfolio.

(3)Our calculation includes OP Units and vested LTIP Units (including vested 2012 OPP Units and vested 2013 - 2021 MYLTIP Units).

Material Cash Commitments

We have various service contracts with vendors related to our property management. In addition, we have certain other contracts we enter into 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, 2024, we paid approximately $80.2 million to fund tenant-related obligations, including tenant improvements and leasing commissions.

In addition, during the three months ended September 30, 2024, we and our unconsolidated joint venture partners incurred approximately $120.8 million of new tenant-related obligations associated with approximately 1.1 million square feet of second generation leases, or approximately $111 per square foot. We signed approximately 15,400 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 third quarter of 2024, we signed leases for approximately 1.1 million square feet of space and incurred aggregate tenant-related obligations of approximately $121.9 million, or approximately $110 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 2021 Credit Facility, unsecured term loans, unsecured commercial paper, 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, 2024, approximately $14.1 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 $2.1 billion of outstanding indebtedness bore interest at variable rates, including approximately $800.0 million of unsecured term loans, $500.0 million of unsecured commercial paper borrowings and approximately $800.0 million of secured debt. However, we 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 in place as of September 30, 2024 and their respective fair values). Therefore, as of September 30, 2024, we have $1.2 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, 2024.

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, 2024, the weighted-average stated interest rates on the fixed rate debt stated above was 3.80% per annum. At September 30, 2024, our outstanding variable rate debt totaled $2.1 billion, of which $900.0 million was subject to interest rate swaps. At September 30, 2024, the weighted-average stated interest rate on our variable rate debt, including the effect of the interest rate swaps, was 4.38% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.3 million and $15.8 million for the three and nine months ended September 30, 2024.

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.

PART II. OTHER INFORMATION

ITEM 1—Legal Proceedings.

We are subject to 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 our financial position, results of operations or liquidity.

ITEM 1A—Risk Factors.

Except to the extent updated below or to the extent factual information disclosed elsewhere in this Quarterly Report on Form 10-Q relates to such risk factors (including, without limitation, the matters discussed in Part I, “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations”), there were no material changes to the risk factors disclosed in Part I, “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2023.

The use of technology based on artificial intelligence and machine learning presents risks and challenges that may adversely affect our business and results of operations.

We use artificial intelligence and machine learning technology (collectively, “AI”) capabilities with the goal to enhance efficiencies in conducting our business. Our deployment and application of AI remains ongoing. While these AI tools hold promise in optimizing our work processes and driving efficiencies, they also present risks, challenges and unintended consequences that could adversely affect our business and results of operations or those of our clients. These include, but are not limited to:

•the release, leak or disclosure of proprietary, confidential, sensitive or otherwise valuable information as a result of or in connection with our use of AI tools,

•the incorporation of AI by our clients, vendors, contractors and other third-parties into their products or services, with or without our knowledge, in a manner that could give rise to issues pertaining to data privacy, information security and intellectual property considerations, and

•the evolving legal regulations relating to AI, which may require significant resources to modify and maintain business practices to comply with applicable law or otherwise result in legal or regulatory action or create additional liabilities, the nature of which cannot be determined at this time.

While we aim to use AI responsibly and securely and attempt to mitigate ethical and legal issues presented by its use, we may ultimately be unsuccessful in identifying or resolving issues before they arise. There can be no assurance that we will properly implement AI, and the failure to do so could have a material adverse effect on our results of operations or financial condition.
