BXP, Inc. (NYSE: BXP) (formerly known as Boston Properties, Inc.) (“BXP” or the “Company”) is the largest publicly traded developer, owner, and manager of premier workplaces in the United States, concentrated in six dynamic gateway markets - Boston, Los Angeles, New York, San Francisco, Seattle, and Washington, DC. BXP has delivered places that power progress for our clients and communities for more than 50 years. BXP is a fully integrated real estate company, organized as a real estate investment trust (REIT). Including properties owned by joint ventures, BXP’s portfolio totals 53.5 million square feet and 186 properties, including 10 properties under construction/redevelopment. BXP’s properties include 164 office properties, 14 retail properties (including one retail property under construction), seven residential properties (including two residential properties under construction) and one hotel. BXP is well-known for its in-house building management expertise and responsiveness to clients’ needs. BXP holds a superior track record of developing premium Central Business District (CBD) office buildings, successful mixed-use complexes, suburban office centers and build-to-suit projects for a diverse array of creditworthy clients. BXP actively works to promote its growth and operations in a sustainable and responsible manner.  BXP has earned a twelfth consecutive GRESB “Green Star” recognition and the highest GRESB 5-star Rating and was named one of the world’s most sustainable companies by TIME Magazine.

On July 1, 2024, BXP formally completed the change of its corporate name from Boston Properties, Inc. to BXP, Inc. Having grown to six regions, the change telegraphed to stakeholders that while Boston remains a key part of BXP’s history, founding, and portfolio, future growth will come throughout its regions: Boston, Los Angeles, New York, San Francisco, Seattle, and Washington, DC. BXP aspires to be the real estate industry partner of choice and premier workplace leader in all of the cities in which it operates, and the evolution of BXP’s name reflects a national, not singular city, focus.

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 the impact of changes in general economic and capital market conditions, including continued inflation, high interest rates, supply chain disruptions, labor market 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, 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 geopolitical conflicts, the immediate and long-term impact of the outbreak of a highly infectious or contagious disease on our and our clients’ financial condition, results of operations and cash flows (including the impact of actions taken to contain the outbreak or mitigate its impact, the direct and indirect economic effects of the outbreak and containment measures on our clients, and the ability of our clients to successfully operate their businesses), 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 (including costs to comply with the Securities and Exchange Commission’s rules to standardize climate-related disclosures) 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.

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 57.

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 61.

BXP’s guidance for the third quarter 2024 and full year 2024 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 30, 2024 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 59. 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 $4 and $91 for the three months ended June 30, 2024 and 2023, respectively. As of June 30, 2024, the Company has remaining lease payments aggregating approximately $31.2 million, all of which it expects to incur by the end of 2026 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 2026 may vary significantly.

For the period from January 1, 2024 through June 30, 2024

___________________

1 The Company completed the acquisition of its joint venture partner’s 50% economic ownership interest. The property is encumbered by an approximately $207.1 million mortgage, which bears interest at 3.61% per annum and matures on January 5, 2025. Following the acquisition, the Company modified the mortgage loan to provide for two loan extension options totaling five years of additional term, each subject to certain conditions. The first loan extension option, which provides for an additional term of four years, is at a fixed interest rate of 5.0% per annum. In addition, following the acquisition, BXP extended the 214,000 square foot lease with anchor client, Finnegan Henderson Farabow Garrett & Dunner, L.L.P., through 2042 and agreed to complete approximately $25.0 million of building enhancements.

2 The Company completed the previously announced sale of a 45% ownership interest to Norges Bank Investment Management (“NBIM”). NBIM’s investment in 290 Binney Street will reduce the Company’s share of the project’s estimated development spend over time by approximately $533.5 million, see page 15. At closing, NBIM paid approximately $142 million, of which $97 million was a special distribution to the Company and represented pre-formation costs, and NBIM will fund all capital calls until reaching 45% of invested capital. The Company retains a 55% ownership interest and provides 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.

7The project budget reflects the Company’s 55% share of joint venture costs related to 290 Binney Street. The Company has the sole obligation to construct an underground electrical vault for an estimated gross cost of $183.9 million. Upon completion, the Company has entered into a contract to sell the electrical vault to a third party for a fixed price of $84.1 million. The net investment of $99.8 million will be included in the Company’s outside basis in 290 Binney Street. The Company has invested $47.1 million for the vault as of June 30, 2024.

8Total percentage leased excludes Residential.
