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, the impact of geopolitical conflicts, the uncertainties of investing in new markets, the costs and availability of financing, the effectiveness of our interest rate 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 also presents “BXP’s Share” of certain of these measures, which are 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.

•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;

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

•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;

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

Guidance and assumptions

GUIDANCE

BXP’s guidance for the third quarter and full year 2025 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 July 29, 2025 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, (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.

The ground lease was entered into in 2020 with a third party hotel developer and amended in 2022. The amendment resulted in the derecognition of the assets related to the ground lease and the classification of the ground lease as a sales-type lease resulting in the recognition of a gain on sales-type lease of approximately $10.1 million.

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 $(83) and $4 for the three months ended June 30, 2025 and 2024, respectively. As of June 30, 2025, the Company has remaining lease payments aggregating approximately $30.6 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. Lease transaction costs are generally included in 2nd generation tenant improvements and leasing commissions in the Company’s FAD calculation on page 8.

3Pages 21-24 indicate by footnote the properties that are not included as part of Same Property NOI. In addition, Same Properties exclude properties that were sold prior to June 30, 2025 and therefore are no longer a part of the Company’s property portfolio.

1 The Company has agreed to fund up to $65.0 million in preferred equity. The joint venture has also entered into a $225.0 million construction loan, of which the Company’s share is approximately $43.8 million. As of June 30, 2025, $1.6 million of preferred equity has been contributed and no amounts have been drawn under the construction loan.

2 The Company entered into a joint venture with a third party to redevelop, own and operate 17 Hartwell Avenue. The Company sold 17 Hartwell Avenue to the joint venture for approximately $21.8 million in cash. The Company also contributed development costs of approximately $5.6 million for its 20% ownership interest. The Company will be the development manager for the project. Upon formation of the joint venture, the Company ceased accounting for the property on a consolidated basis and is accounting for the joint venture entity on an unconsolidated basis using the equity method of accounting, as it does not have a controlling financial or operating interest in the joint venture entity.

The Company recognized a gain upon sale of the real estate of approximately $18.4 million within Gain on Sale of Real Estate on the Consolidated Statement of Operations, as the fair value of the real estate exceeded its carrying value.
