FORWARD-LOOKING STATEMENTS

This Supplemental package contains “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. You can identify these statements by our use of the words “anticipates,” “believes,” “budgeted,” “could,” “estimates,” “expects,” “guidance,” “intends,” “may,” “might,” “plans,” “projects,” “should,” “will,” and similar expressions that do not relate to historical matters. These statements are based on our current plans, expectations, projections and assumptions about future events. You should exercise caution in interpreting and relying on forward-looking statements because they involve known and unknown risks, uncertainties and other factors which are, in some cases, beyond BXP’s control. If our underlying assumptions prove inaccurate, or known or unknown risks or uncertainties materialize, actual results could differ materially from those expressed or implied by the forward-looking statements. These factors include, without limitation, the risks and uncertainties related to adverse changes in general economic and capital market conditions, including continued inflation, elevated interest rates, supply chain disruptions, dislocation and volatility in capital markets, potential longer-term changes in consumer and client behavior resulting from the severity and duration of any downturn in the U.S. or global economy, general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases on favorable terms, sustained changes in client preferences and space utilization, dependence on clients’ financial condition, and competition from other developers, owners and operators of real estate), the impact of adverse political conditions, including policy changes by the presidential administration, such as the direct and indirect negative impacts that new and increased tariffs may have on (1) our current and prospective clients and their demand for office space and (2) the costs and availability of construction materials and the economic returns on our construction and development activities, and prolonged government shutdowns or disruptions, the impact of geopolitical conflicts, the uncertainties of investing in new markets, the costs and availability of financing, the effectiveness of our hedging contracts, the ability of our joint venture partners to satisfy their obligations, the effects of local, national and international economic and market conditions, the effects of acquisitions, dispositions and possible impairment charges on our operating results, the impact of newly adopted accounting principles on the Company’s accounting policies and on period-to-period comparisons of financial results, the uncertainties of costs to comply with regulatory changes and other risks and uncertainties detailed from time to time in the Company’s filings with the Securities and Exchange Commission. These forward-looking statements speak only as of the date of issuance of this report and are not guarantees of future results, performance or achievements. BXP does not undertake a duty to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as otherwise required by law.

NON-GAAP FINANCIAL MEASURES

This Supplemental package includes non-GAAP financial measures, which are accompanied by what the Company considers the most directly comparable financial measures calculated and presented in accordance with GAAP. Quantitative reconciliations of the differences between the most directly comparable GAAP financial measures and the non-GAAP financial measures presented are provided within this Supplemental package. Definitions of these non-GAAP financial measures and statements of the reasons why management believes the non-GAAP measures provide useful information to investors about the Company’s financial condition and results of operations, and, if applicable, the other purposes for which management uses the measures, can be found in the Definitions section of this Supplemental starting on page 56.

The Company presents “BXP’s Share” of certain non-GAAP financial measures that are calculated as the consolidated amount calculated in accordance with GAAP, plus the Company’s share of the amount from the Company’s unconsolidated joint ventures (calculated based upon the Company’s percentage ownership interest and, in some cases, after priority allocations), minus the Company’s partners’ share of the amount from the Company’s consolidated joint ventures (calculated based upon the partners’ percentage ownership interests and, in some cases, after income allocation to private REIT shareholders and their share of fees due to the Company). Management believes that presenting “BXP’s Share” of these measures provides useful information to investors regarding the Company’s financial condition and/or results of operations because 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, management believes that presenting BXP’s Share of various financial measures in this manner can help investors better understand the Company’s financial condition and/or results of operations after taking into account its true economic interest in these joint ventures. The Company cautions investors that the ownership percentages used in calculating “BXP’s Share” of these measures 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 routine and major decisions), distributions, transferability of interests, financings and guarantees, liquidations and other matters. As a result, presentations of “BXP’s Share” of a financial measure 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. Unless noted otherwise, reconciliations of “BXP’s Share” of these financial measures can be found in the Reconciliations section of this Supplemental package starting on page 60.

STRATEGY

BXP’s primary business objective is to maximize return on investment in an effort to provide its investors with the greatest possible total return in all points of the economic cycle. To achieve this objective, the key tenets of our long-term business strategy are to:

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

•maintain a keen focus on select dynamic gateway markets that exhibit the strongest economic growth and investment characteristics over time - currently Boston, Los Angeles, New York, San Francisco, Seattle, and Washington, DC;

•invest in the highest quality buildings (primarily premier workplaces) with unique amenities and desirable locations that are able to maintain high occupancy rates and achieve premium rental rates through economic cycles;

•maintain scale and a full-service real estate capability (leasing, development, construction, marketing, legal, and property management) in our markets to ensure we (1) see all relevant investment deal flow, (2) maintain an ability to execute on all types of real estate opportunities, such as acquisitions, dispositions, repositioning and development, throughout the real estate investment cycle, (3) provide superior service to our clients and (4) develop and manage our assets in the most sustainable manner possible;

•ensure a strong balance sheet to maintain consistent access to equity and debt capital and the ability to make new investments at opportune times;

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

•recycle capital for future investment through disposing of assets that no longer meet our investment profile or provide an opportunity for an attractive sale price relative to reinvestment;

•maintain a leadership position in sustainability innovation to minimize emissions from BXP’s development and in-service portfolio, as well as to provide clients sustainable solutions for their space use needs; and

•foster a culture and reputation of integrity, excellence and purposefulness, making us the employer of choice for talented real estate professionals, the landlord and developer of choice for our clients, as well as the counterparty of choice for real estate industry participants.

			Q3 2026
			Guidance and assumptions

GUIDANCE

BXP’s guidance for full year 2026 for diluted earnings per common share attributable to BXP, Inc. (EPS) and diluted funds from operations (FFO) per common share attributable to BXP, Inc. is set forth and reconciled below. Except as described below, the estimates reflect management’s view of current and future market conditions, including assumptions with respect to rental rates, occupancy levels, interest rates, the timing of the lease-up of available space, the timing of development cost outlays and development deliveries, and the earnings impact of the events referenced in the Company’s earnings release issued on October 27, 2026 and those referenced during the related conference call. The estimates do not include (1) possible future gains or losses or the impact on operating results from other possible future property acquisitions or dispositions not under contract as of the date hereof, (2) the impacts of any other capital markets activity, (3) future write-offs or reinstatements of accounts receivable and accrued rent balances, or (4) future impairment charges. EPS estimates may fluctuate as a result of several factors, including changes in the recognition of depreciation and amortization expense, impairment losses on depreciable real estate, and any gains or losses associated with disposition activity. BXP is not able to assess at this time the potential impact of these factors on projected EPS. By definition, FFO does not include real estate-related depreciation and amortization, impairment losses on depreciable real estate, or gains or losses associated with disposition activities. For a complete definition of FFO and statements of the reasons why management believes it provides useful information to investors, see page 58. There can be no assurance that BXP’s actual results will not differ materially from the estimates set forth below.

1In light of the front-ended, uneven rental payments required by the Company’s 99-year ground and air rights lease for the 100 Clarendon Street garage and Back Bay Transit Station in Boston, MA, and to make period-to-period comparisons more meaningful to investors, the adjustment does not include the straight-line impact of approximately $(6,084) and $(1,061) for the three months ended September 30, 2026 and 2025, respectively. As of September 30, 2026, the Company has remaining lease payments aggregating approximately $9.3 million, all of which it expects to incur by the end of 2027 with no payments thereafter. Under GAAP, the Company recognizes expense of $(111) per quarter on a straight-line basis over the term of the lease. However, unlike more traditional ground and air rights leases, the timing and amounts of the rental payments by the Company correlate to the uneven timing and funding by the Company of capital expenditures related to improvements at Back Bay Transit Station. As a result, the amounts excluded from the adjustment each quarter through 2027 may vary significantly.

2Consists of lease transaction costs that qualify as rent inducements in accordance with GAAP. Lease transaction costs are generally included in 2nd generation tenant improvements and leasing commissions in the Company’s FAD calculation on page 8.

1The Company previously recognized an impairment loss.

2Including approximately $9.0 million of tenant improvement obligations assumed by the buyer, the total consideration is approximately $101.4 million.

3The Company completed a partial equity interest sale to AVRS Partners of 10.55%. The partner agreed to invest an aggregate of $81.5 million, of which $50.7 million was invested at closing. The partner’s investment excludes its share of equity carry. The Company retains an 89.45% ownership interest and will provide development, property management, and leasing services for the venture. This 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.

1The GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, the effects of hedging transactions (excluding capped calls classified as equity) and adjustments required to reflect loans and swaps at their fair values upon consolidation.

2The stated interest rate includes the effects of hedging transactions.

3All unsecured senior notes and unsecured exchangeable senior notes are rated BBB (negative), and Baa2 (stable) by S&P and Moody’s, respectively.

4The GAAP interest rate excludes capped call transactions that are classified as equity. The initial exchange rate of the unsecured exchangeable senior notes is 10.8180 shares of BXP’s common stock per $1,000 principal amount of notes, which represents an initial exchange price of approximately $92.44 per share of BXP’s common stock. In conjunction with the issuance of the unsecured exchangeable senior notes, the Company entered into capped call transactions to cover, subject to customary adjustments, the number of shares of BXP’s common stock initially underlying the unsecured exchangeable senior notes. The capped call transactions are expected generally to reduce the potential dilution to BXP’s common stock upon any exchange of notes and/or offset any cash payments BPLP is required to make in excess of the principal amount of exchanged notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the capped call transactions is initially $105.64 per share, which represents a premium of 40% over the last reported sale price of $75.46 per share of BXP’s common stock on September 24, 2025, and is subject to certain adjustments under the terms of the capped call transactions. The capped call transactions will expire upon the maturity of the unsecured exchangeable senior notes, if not earlier exercised or terminated, and the premiums associated with the purchase were classified as equity.

5Values are based on the September 30, 2026 closing price of $61.11 per share of BXP common stock.

6Amount is calculated based on the Company’s percentage ownership interest in the unconsolidated joint venture entities. For additional detail, see page 35.

7Amount is calculated based on the outside partners’ percentage ownership interest in the consolidated joint venture entities. For additional detail, see page 33.

1Excludes unconsolidated joint ventures. For information on BXP’s share of unconsolidated joint venture debt, see page 35.

2Includes $1.0 billion in aggregate principal amount of BPLP’s 2.750% senior unsecured notes which was repaid at par on October 1, 2026.

3The unsecured commercial paper program is backstopped by available capacity under the unsecured line of credit. As such, the Company intends to maintain, at a minimum, availability under its unsecured line of credit in an amount equal to the amount of commercial paper notes outstanding. The term of the notes issued under the unsecured commercial paper program vary but may not exceed one year from the date of issuance. The commercial paper notes are included in the Company’s floating rate debt statistics. At September 30, 2026, the weighted average interest rate of the commercial paper notes outstanding was approximately 4.18% per annum and had a weighted-average maturity of 29 days from the date of issuance and therefore, the balance is reflected in the period 2026 within the Principal due at Maturity chart.

4The 2024 Unsecured Term Loan has a one-year extension option remaining, subject to certain conditions.

5The Unsecured Term Loan Facility has two, six-month extension options, each subject to customary conditions.

6The GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, the effects of hedging transactions (excluding capped calls classified as equity) and adjustments required to reflect loans and swaps at their fair values upon consolidation.

7The Fixed Rate Debt includes the effects of hedging transactions, excluding capped calls treated as equity.


			Q3 2026
			Senior unsecured debt covenant compliance ratios

In the fourth quarter of 2002, the Company’s Operating Partnership (Boston Properties Limited Partnership) received investment grade ratings on its senior unsecured debt securities and thereafter issued unsecured notes. The notes were issued under an indenture, dated as of December 13, 2002, by and between Boston Properties Limited Partnership and The Bank of New York Mellon Trust Company, N.A., as trustee, as supplemented from time to time (the “Indenture”), which, among other things, requires us to comply with the following limitations on incurrence of debt: Limitation on Outstanding Debt; Limitation on Secured Debt; Ratio of Annualized Consolidated EBITDA to Annualized Interest Expense; and Maintenance of Unencumbered Assets. Compliance with these restrictive covenants requires us to apply specialized terms the meanings of which are described in detail in our filings with the SEC, and to calculate ratios in the manner prescribed by the Indenture.

This section presents such ratios as of September 30, 2026 to show that the Company’s Operating Partnership was in compliance with the terms of the Indenture, which has been filed with the SEC. Management is not presenting these ratios for any other purpose or for any other period, and is not intending for these measures to otherwise provide information to investors about the Company’s financial condition or results of operations. Investors should not rely on these measures other than for purposes of testing our compliance with the Indenture.

_____________

1Amounts represent BXP’s share based on its ownership percentage.

2The GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, which includes mortgage recording fees, the effects of hedging transactions (if any) and adjustments required under Accounting Standards Codification 805 “Business Combinations” to reflect loans at their fair values (if any).

3The construction financing has a borrowing capacity of $98.7 million.

4The Company completed the sale of the property on September 17, 2025 and is currently in the process of dissolving the joint venture.

5This investment includes a net deficit balance from the amenity joint venture.

As of September 30, 2026, the Company has funded approximately $28.6 million of the mezzanine loan. The loan is reflected as related party notes receivable, net on the Company’s Consolidated Balance Sheets.

7The construction financing has a borrowing capacity of $225.0 million.

			Q3 2026
			Definitions

This section contains definitions of certain non-GAAP financial measures and other terms that the Company uses in this Supplemental report and, if applicable, the reasons why management believes these non-GAAP financial measures provide useful information to investors about the Company’s financial condition and results of operations and the other purposes for which management uses the measures. Additional detail can be found in the Company’s most recent annual report on Form 10-K and quarterly report on Form 10-Q, as well as other documents the Company files or furnishes to the SEC from time to time.

The Company may also present "BXP's Share" of certain operating metrics, such as occupancy and leased percentages based upon square footage. Amounts are calculated based on our consolidated portfolio square feet, plus our share of the square feet from the unconsolidated joint venture properties (calculated based on our ownership percentage), minus our partners’ share of square feet from our consolidated joint venture properties (calculated based upon the partners’ percentage ownership interests).

Annualized Rental Obligations

Annualized Rental Obligations is defined as monthly Rental Obligations, as of the last day of the reporting period, multiplied by twelve (12).

Average Economic Occupancy

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.

Average Monthly Rental Rates

Average Monthly Rental Rates are calculated by the Company 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.

Average Physical Occupancy

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.

Debt to Market Capitalization Ratio

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of leverage commonly used by analysts in the REIT sector that equals the quotient of (A) the Company’s Consolidated Debt divided by (B) the Company’s Consolidated Market Capitalization, presented as a percentage. Consolidated Market Capitalization is the sum of (x) the Company’s Consolidated Debt plus (y) the market value of the Company’s outstanding equity securities calculated using the closing price per share of common stock of the Company, as reported by the New York Stock Exchange, multiplied by the sum of (1) outstanding shares of common stock of the Company, (2) outstanding common units of limited partnership interest in Boston Properties Limited Partnership (excluding common units held by the Company), (3) common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, (4) common units issuable upon conversion of 2012 OPP Units that were issued in the form of LTIP Units, and (5) common units issuable upon conversion of 2013-2023 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 or Outperformance Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2024, 2025 and 2026 MYLTIP Units and 2025 Outperformance Units are not included.

The Company also presents BXP’s Share of Market Capitalization, which is calculated in a similar manner, except that BXP’s Share of Debt is utilized instead of the Company’s Consolidated Debt in both the numerator and the denominator. The Company presents these ratios because its degree of leverage could affect its 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 the Company, and as such will fluctuate with changes in such price and do not necessarily reflect the Company’s capacity to incur additional debt to finance its activities or its ability to manage its existing debt obligations. However, for a company like BXP, Inc., 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 the Company’s outstanding indebtedness.


			Q3 2026
			Definitions (continued)

Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate (EBITDAre)

Pursuant to the definition of Earnings Before Interest, Taxes, Depreciation and Amortization for Real Estate adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“Nareit”), the Company calculates EBITDAre as net income (loss) attributable to BXP, Inc, the most directly comparable GAAP financial measure, plus net (income) loss attributable to noncontrolling interests, interest expense, losses (gains) from early extinguishments of debt, depreciation and amortization expense, impairment losses and adjustments to reflect the Company’s share of EBITDAre from unconsolidated joint ventures less gains (losses) on sales of real estate and sales-type leases. EBITDAre is a non-GAAP financial measure. The Company uses EBITDAre internally as a performance measure and believes EBITDAre provides useful information to investors regarding its financial condition and results of operations at the corporate level because, when compared across periods, EBITDAre reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, general and administrative expenses and acquisition and development activities on an unleveraged basis, providing perspective not immediately apparent from net income (loss) attributable to BXP, Inc.

In some cases the Company also presents (A) BXP’s Share of EBITDAre – cash, which is BXP’s Share of EBITDAre after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a client), fair value lease revenue, amortization and accretion of sales type lease receivable, non-cash termination income adjustment (fair value lease amounts) and non-cash gains (losses) from early extinguishment of debt and adding straight-line ground rent expense (excluding prepaid ground rent expense), stock-based compensation expense and lease transaction costs that qualify as rent inducements, and (B) Annualized EBITDAre, which is EBITDAre for the applicable fiscal quarter ended multiplied by four (4). Presenting BXP’s Share of EBITDAre – cash allows investors to compare EBITDAre across periods without taking into account the effect of certain non-cash rental revenues, ground rent expense and stock based compensation expense. Similar to depreciation and amortization, because of historical cost accounting, fair value lease revenue may distort operating performance measures at the property level. Additionally, presenting EBITDAre excluding the impact of straight-line rent provides investors with an alternative view of operating performance at the property level that more closely reflects rental revenue generated at the property level without regard to future contractual increases in rental rates. In addition, the Company’s management believes that the presentation of Annualized EBITDAre provides useful information to investors regarding the Company’s results of operations because it enables investors to more easily compare quarterly EBITDAre to EBITDAre from full fiscal years.

The Company’s computation of EBITDAre may not be comparable to EBITDAre 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. The Company believes that in order to facilitate a clear understanding of its operating results, EBITDAre should be examined in conjunction with net income (loss) attributable to BXP, Inc. as presented in the Company’s consolidated financial statements. EBITDAre should not be considered a substitute to net income (loss) attributable to BXP, Inc. in accordance with GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP.

Fixed Charge Coverage Ratio

Fixed Charge Coverage Ratio equals BXP’s Share of EBITDAre – cash divided by Total Fixed Charges. BXP’s Share of EBITDAre – cash is a non-GAAP financial measure equal to BXP’s Share of EBITDAre after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a client), fair value lease revenue, amortization and accretion related to sales type lease receivable, non-cash termination income adjustment (fair value lease amounts) and non-cash gains (losses) from early extinguishment of debt and adding straight-line ground rent expense, stock-based compensation expense and lease transaction costs that qualify as rent inducements. Total Fixed Charges is also a non-GAAP financial measure equal to the sum of BXP’s Share of interest expense, capitalized interest, maintenance capital expenditures, hotel improvements, equipment upgrades and replacements and preferred dividends/distributions less hedge amortization and amortization of financing costs. The Company believes that the presentation of its Fixed Charge Coverage Ratio provides investors with useful information about the Company’s financial performance as it relates to overall financial flexibility and balance sheet management. Furthermore, the Company believes that the Fixed Charge Coverage Ratio is frequently used by analysts, rating agencies and other interested parties in the evaluation of the Company’s performance as a REIT and, as a result, by presenting the Fixed Charge Coverage Ratio the Company assists these parties in their evaluations. The Company’s calculation of its Fixed Charge Coverage Ratio may not be comparable to the ratios reported by other REITs or real estate companies that define the term differently and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP. For clarification purposes, this ratio does not include gains (losses) from early extinguishments of debt.

Funds Available for Distribution (FAD) and FAD Payout Ratio

In addition to FFO, which is defined on the following page, the Company presents Funds Available for Distribution to common shareholders and common unitholders (FAD), which is a non-GAAP financial measure that is calculated by (1) adding to FFO lease transaction costs that qualify as rent inducements, non-real estate depreciation and amortization, non-cash losses (gains) from early extinguishments of debt, stock-based compensation expense, partners’ share of consolidated and unconsolidated joint venture 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences) and unearned portion of capitalized fees, (2) eliminating the effects of straight-line rent, straight-line ground rent expense adjustment (excluding prepaid ground rent expense), hedge amortization, fair value interest adjustment, fair value lease revenue and amortization and accretion related to sales type lease receivable, and (3) subtracting maintenance capital expenditures, hotel improvements, equipment upgrades and replacements, 2nd generation tenant improvement and leasing commissions (included in the period in which the lease commences), non-cash termination income adjustment (fair value lease amounts) and impairments of non-depreciable real estate. The Company believes that the presentation of FAD provides useful information to investors regarding the Company’s results of operations because FAD provides supplemental information regarding the Company’s operating performance that would not otherwise be available and may be useful to investors in assessing the Company’s operating performance. Additionally, although the Company does not consider FAD to be a liquidity measure, as it does not make adjustments to reflect changes in working capital or the actual timing of the payment of income or expense items that are accrued in the period, the Company believes that FAD may provide investors with useful supplemental information regarding the Company’s ability to generate cash from its operating performance and the impact of the Company’s operating performance on its ability to make distributions to its shareholders. Furthermore, the Company believes that FAD is frequently used by analysts, investors and other interested parties in the evaluation of its performance as a REIT and, as a result, by presenting FAD the Company is assisting these parties in their evaluation. FAD should not be considered as a substitute for net income (loss) attributable to BXP, Inc.’s co determined in accordance with GAAP or any other GAAP financial measures and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP.

FAD Payout Ratio is defined as distributions to common shareholders and unitholders (excluding any special distributions) divided by FAD.


			Q3 2026
			Definitions (continued)

Funds from Operations (FFO)

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of Nareit, the Company calculates Funds from Operations, or “FFO,” by adjusting net income attributable to BXP, Inc. (computed in accordance with GAAP) for gains (or losses) from sales of properties or a change in control, impairment losses on depreciable real estate consolidated on the Company’s balance sheet, impairment losses on its 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 real estate-related depreciation and amortization. FFO is a non-GAAP financial measure, but the Company believes the presentation of FFO, combined with the presentation of required GAAP financial measures, has improved the understanding of operating results of REITs among the investing public and has helped make comparisons of REIT operating results more meaningful. Management generally considers FFO and FFO per share to be useful measures for understanding and comparing the Company’s 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 and FFO per share can help investors compare the operating performance of a company’s real estate across reporting periods and to the operating performance of other companies.

The Company’s 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. In order to facilitate a clear understanding of the Company’s operating results, FFO should be examined in conjunction with net income attributable to BXP, Inc. as presented in the Company’s consolidated financial statements. FFO should not be considered as a substitute for net income attributable to BXP, Inc. (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to the Company’s financial information prepared in accordance with GAAP.

In-Service Properties

The Company treats a property as being “in-service” upon the earlier of (1) lease-up and completion of tenant improvements or (2) one year after cessation of major construction activity as determined under GAAP. The determination as to when an entire property should be treated as “in-service” involves a degree of judgment and is made by management based on the relevant facts and circumstances of the particular property. For portfolio operating and occupancy statistics, the Company specifies a single date for treating a property as “in-service,” which is generally later than the date the property is partially placed in-service under GAAP. Under GAAP, a property may be placed in-service in stages as construction is completed and the property is held available for occupancy. In addition, under GAAP, when a portion of a property has been substantially completed and either occupied or held available for occupancy, the Company ceases capitalizing costs on that portion, even though it may not treat the property as being “in-service,” and continues to capitalize only those costs associated with the portion still under construction. In-service properties include properties held by the Company’s unconsolidated joint ventures. A property will no longer be considered “in-service” when the occupied percentage is below 50% and the Company anticipates a future development/redevelopment of the property.

Interest Coverage Ratio

Interest Coverage Ratio, calculated including and excluding capitalized interest, is a non-GAAP financial measure equal to BXP’s Share of EBITDAre – cash divided by Adjusted interest expense. BXP’s Share of EBITDAre – cash is a non-GAAP financial measure equal to BXP’s Share of EBITDAre after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a client), fair value lease revenue, amortization and accretion related to sales type lease receivable, non-cash termination income adjustment (fair value lease amounts) and non-cash gains (losses) from early extinguishment of debt and adding straight-line ground rent expense (excluding prepaid ground rent expense), stock-based compensation expense and lease transaction costs that qualify as rent inducements. Adjusted interest expense excluding capitalized interest is equal to BXP’s Share of interest expense less (1) BXP’s Share of hedge amortization, (2) BXP’s Share of fair value interest adjustment and (3) BXP’s Share of amortization of financing costs. Adjusted interest expense including capitalized interest is calculated in the same manner but adds back BXP’s Share of capitalized interest. The Company believes that the presentation of its Interest Coverage Ratio provides useful information about the Company’s financial condition because it provides investors additional information on the Company’s ability to meet its debt obligations and incur additional indebtedness. In addition, by analyzing interest coverage ratios over a period of time, trends may emerge that provide investors a better sense of whether a company’s financial condition is improving or declining. The ratios may also be used to compare the financial condition of different companies, which can help when making an investment decision. The Company presents its Interest Coverage Ratio in two ways - including capitalized interest and excluding capitalized interest. GAAP requires the capitalization of interest expense during development. Therefore, for a company like BXP, Inc. that is an active developer of real estate, presenting the Interest Coverage Ratio (excluding capitalized interest) provides an alternative measure of financial condition that may be more indicative of the Company’s ability to meet its interest expense obligations and therefore its overall financial condition. For clarification purposes, this ratio does not include gains (losses) from early extinguishments of debt.

Market Rents

Market Rents used by the Company in calculating Average Economic Occupancy are based on the current market rates set by the managers of the Company’s residential properties based on their experience in renting their residential property’s units and publicly available market data. Trends in market rents for a region as reported by others could therefore vary materially. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Net Debt

Net Debt is equal to (A) the Company’s consolidated debt plus special dividends payable (if any) less (B) cash and cash equivalents and cash held in escrow for potential Section 1031 like kind exchange(s) (if any). The Company believes that the presentation of Net Debt provides useful information to investors because the Company reviews Net Debt as part of the management of its overall financial flexibility, capital structure and leverage. In particular, Net Debt is an important component of the Company’s ratio of BXP’s Share of Net Debt to BXP’s Share of EBITDAre. BXP’s Share of Net Debt is calculated in a similar manner to Net Debt, except that (1) BXP’s Share of Debt is utilized instead of the Company’s consolidated debt after eliminating BXP’s Share of the related party note receivable and (2) BXP’s Share of cash is utilized instead of consolidated cash. The Company believes BXP’s Share of Net Debt to BXP’s Share of EBITDAre is useful to investors because it provides an alternative measure of the Company’s financial flexibility, capital structure and leverage based on its percentage ownership interest in all of its assets. Furthermore, certain debt rating agencies, creditors and credit analysts monitor the Company’s Net Debt as part of their assessments of its business. The Company may utilize a considerable portion of its cash and cash equivalents at any given time for purposes other than debt reduction. In addition, cash and cash equivalents and cash held in escrow for potential Section 1031 like kind exchange(s) may not be solely controlled by the Company. The deduction of these items from consolidated debt in the calculation of Net Debt therefore should not be understood to mean that these items are available exclusively for debt reduction at any given time.


			Q3 2026
			Definitions (continued)

Net Operating Income (NOI)

Net operating income (NOI) is a non-GAAP financial measure equal to net income (loss) attributable to BXP, Inc., the most directly comparable GAAP financial measure, plus (1) net (income) loss attributable to noncontrolling interests, corporate general and administrative expense, payroll and related costs from management services contracts, transaction costs, depreciation and amortization expense, impairment losses, loss from early extinguishment of debt, and interest expense, less (2) development and management services revenue, direct reimbursements of payroll and related costs from management services contracts, income (loss) from unconsolidated joint ventures, gains (losses) on sales of real estate or sales type leases, gains (losses) from investments in securities, unrealized gain (loss) on non-real estate investments, and interest and other income. In some cases, the Company also presents (1) NOI – cash, which is NOI after eliminating the effects of straight-line rent (excluding the impact related to deferred revenue related to improvements to long-lived assets paid for by a client), fair value lease revenue, amortization and accretion related to sales type lease, straight-line ground rent expense adjustment (excluding prepaid ground rent), prepaid ground rent expense and lease transaction costs that qualify as rent inducements in accordance with GAAP, and (2) NOI and NOI – cash, in each case excluding termination income.

The Company uses these measures internally as performance measures and believes they provide useful information to investors regarding the Company’s results of operations and financial condition because, when compared across periods, they reflect 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). 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. Presenting NOI – cash allows investors to compare NOI performance across periods without taking into account the effect of certain non-cash rental revenues, amortization and accretion related to sales type lease receivable and ground rent expenses. Similar to depreciation and amortization expense, fair value lease revenues, because of historical cost accounting, may distort operating performance measures at the property level. Additionally, presenting NOI excluding the impact of the straight-lining of rent and amortization and accretion related to sale type lease receivable provides investors with an alternative view of operating performance at the property level that more closely reflects net cash generated at the property level on an unleveraged basis. Presenting NOI measures that exclude termination income provides investors with additional information regarding operating performance at a property level that allows them to compare operating performance between periods without taking into account termination income, which can distort the results for any given period because they generally represent multiple months or years of a client’s rental obligations that are paid in a lump sum in connection with a negotiated early termination of the client’s lease and are not reflective of the core ongoing operating performance of the Company’s properties.

Rental Obligations

Rental Obligations is defined as the contractual base rents (but excluding percentage rent) and budgeted reimbursements from clients under existing leases. These amounts exclude rent abatements.

Rental Revenue

Rental Revenue is equal to Total revenue, the most directly comparable GAAP financial measure, less development and management services revenue and direct reimbursements of payroll and related costs from management services contracts. The Company uses 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. The Company also presents Rental Revenue (excluding termination income) because termination income can distort the results for any given period because it generally represents multiple months or years of a client’s rental obligations that are paid in a lump sum in connection with a negotiated early termination of the client’s lease and does not reflect the core ongoing operating performance of the Company’s properties.

Same Properties

In the Company’s analysis of NOI, particularly to make comparisons of NOI between periods meaningful, it is important to provide information for properties that were in-service and owned by the Company throughout each period presented. The Company refers to properties acquired or placed in-service prior to the beginning of the earliest period presented and owned by the Company through the end of the latest period presented as “Same Properties.” “Same Properties” therefore exclude properties placed in-service, acquired, repositioned 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. Accordingly, it takes at least one year and one quarter after a property is acquired or treated as “in-service” for that property to be included in “Same Properties.” Pages 21 - 24 indicate by footnote the “In-Service Properties” that are not included in “Same Properties.”

1In light of the front-ended, uneven rental payments required by the Company’s 99-year ground and air rights lease for the 100 Clarendon Street garage and Back Bay Transit Station in Boston, MA, and to make period-to-period comparisons more meaningful to investors, the adjustment does not include the straight-line impact of approximately $(4,527) and $(83) for the three months ended June 30, 2026 and 2025, respectively. As of June 30, 2026, the Company has remaining lease payments aggregating approximately $15.6 million, all of which it expects to incur by the end of 2027 with no payments thereafter. Under GAAP, the Company recognizes expense of $(111) per quarter on a straight-line basis over the term of the lease. However, unlike more traditional ground and air rights leases, the timing and amounts of the rental payments by the Company correlate to the uneven timing and funding by the Company of capital expenditures related to improvements at Back Bay Transit Station. As a result, the amounts excluded from the adjustment each quarter through 2027 may vary significantly.

2Consists of lease transaction costs that qualify as rent inducements in accordance with GAAP.
