Current report

•risks related to the bankruptcy, insolvency, restructuring, workouts or other financial distress of a major client, or a major client’s dissolution, liquidation winding down or cessation of business operations, any of which could adversely affect the income produced by our properties, our cash flow and results of operations, and, as applicable, availability of financing;

Current report

We continue to advance our strategic asset sales plan and remain ahead of the original disposition objectives laid out at our Investor Conference in 2025. We have generated approximately $519.5 million of net sale proceeds during the year and approximately $1.4 billion from asset sales since our Investor Conference. We also have four assets currently under contract for sale, which if completed, would result in aggregate dispositions totaling approximately $1.5 billion.

Current report

As interest rates remain volatile, we continue to actively monitor our financing needs with a focus on mitigating the impact of elevated rates. Although higher interest rates have increased our financing costs and may temper the pace of our earnings growth, we expect the benefits of the strategic action plan initiatives to contribute to earnings growth over time.

Current report

Our occupancy has improved more quickly than anticipated, driven primarily by the leasing of vacant in-service space. Since December 31, 2025, we have executed approximately 1.5 million square feet of leases on vacant in-service space which partially contributed to approximately 240 basis points of occupancy improvement, in addition to approximately 30 basis points attributable to changes in the portfolio. Based on current leasing activity and scheduled lease commencements, we expect total portfolio occupancy to reach approximately 90% by year-end 2026, positioning us ahead of the occupancy growth trajectory outlined at our September 2025 Investor Conference.

Current report

In addition to occupancy growth, improving rental economics are beginning to emerge as an incremental opportunity for growth. Market conditions in Midtown Manhattan, Boston's Back Bay, Reston and, more recently, San Francisco have enabled us to increase rents and, in certain instances, reduce concessions. During the third quarter of 2026, second-generation leasing spreads, for leases executed, increased by approximately 6.5% on a gross basis and approximately 9.3% on a net basis, with particularly strong performance in Midtown Manhattan. We expect that occupancy gains will be supplemented increasingly by the benefit of improving rental economics as leases expire and are renewed or replaced over the coming years.

Current report

On the supply side, new office construction remains limited across most of our markets, which we expect will continue to improve long-term supply-demand fundamentals and reinforce the relative competitiveness of institutional, well-amenitized assets. Against this backdrop of increasing demand, limited new supply and improving pricing power across several of our markets, we are increasingly confident in our ability to improve occupancy and the earnings growth potential of our portfolio.

Current report

We continue to see meaningful absorption across our markets, particularly in locations where tightening availability is driving more constructive client behavior. While continued absorption will be necessary to support a broader macro recovery, clients are increasingly prioritizing financially sound owners, premier workplaces and buildings that are well-capitalized and operated for the long term. We believe these trends position BXP to continue gaining market share.

•an approximately 206,000 square foot lease with a technology company at 500 North Capitol, NW in Washington, DC, and

Current report

•an approximately 112,000 square foot lease renewal with a law firm at Madison Centre in Seattle, Washington.

Current report

On October 28, 2026, the management committee of Weil, Gotshal & Manges LLP, a global law firm (“Weil”), publicly recommended an orderly wind‑down of the firm, and a partnership vote is pending. A consolidated joint venture, in which we own a 60% ownership interest, leases approximately 447,000 square feet of office space to Weil at 767 Fifth Avenue (the General Motors Building) in New York City, New York (the “767 Lease”), and the lease expires on August 31, 2034.

Current report

As of September 30, 2026, our share of the annualized rental obligations under the 767 Lease was approximately $35.8 million, representing approximately 1.2% of our share of total annualized rental obligations. Weil paid rent in full for November 2026.

Current report

Under U.S. GAAP, rental revenue is reported on a straight-line basis over the term of the lease. As of September 30, 2026, our share of the accrued straight-line rent balance associated with the 767 Lease was approximately $19.1 million. If Weil elects to dissolve the partnership, we expect we would establish a reserve for the entire straight-line rent balance at that time. There can be no assurance that a dissolution of Weil will not have a material adverse effect on us.

Current report

We also completed the sale of an approximately 10.55% direct and indirect equity interest in the 343 Madison Avenue development project to an investor, generating additional capital, reducing our required equity commitment, and preserving our full control of the project, including all development, leasing and property management responsibilities.

Current report

During the third quarter of 2026, we completed the sales of Sumner Square and 1330 Connecticut Avenue in Washington, DC. The aggregate gross sales price for these two office properties totaled approximately $155.4 million, resulting in aggregate net proceeds of approximately $150.3 million and gains on sales of real estate of approximately $10.5 million.

These items did not recur during the three months ended September 30, 2026. Additionally, our New York region joint venture properties contributed approximately $6.5 million to the increase for the three months ended September 30, 2026, compared to 2025.

Previous report

During the second quarter of 2026, we continued to advance our strategic asset sales plan and remain ahead of our original disposition objectives. Since January 1, 2026, we have generated approximately $432 million of net sale proceeds and approximately $1.3 billion since our Investor Conference. In addition, five assets are currently under contract for sale, representing approximately $180 million of expected net proceeds, including approximately $120 million anticipated to close during 2026. We also continue to actively market several additional assets. Based on assets currently under contract and those being marketed, we estimate that net disposition proceeds in 2026 could aggregate up to an additional $440 million by year end. We also continue to evaluate additional capital raising opportunities to further enhance liquidity and funding flexibility.

Previous report

Together, these factors provide increased visibility into continued occupancy improvement and position us ahead of the occupancy trajectory for 2026 outlined at our September 2025 Investor Day, reinforcing our confidence in achieving our stated goals.

Previous report

On the supply side, new office construction has effectively slowed to a halt across most of our markets, which we expect will improve long‑term supply‑demand fundamentals and reinforce the relative competitiveness of institutional, well‑amenitized assets. Capital markets sentiment toward the office sector has continued to improve, as reflected in increasing private market transaction activity and greater availability of both debt and equity capital at more attractive pricing. This backdrop is expected to support our leasing momentum, facilitate orderly execution of strategic asset sales, and enable continued capital recycling initiatives throughout 2026.

Previous report

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

Previous wording

Premier workplaces in our five traditional central business district (“CBD”) markets (Boston, New York, San Francisco, Seattle and Washington, DC) have consistently outperformed the broader office market in those CBDs on several key metrics, including occupancy, net absorption levels, rental rates and landlord concessions. This outperformance is evident in BXP’s portfolio where we derive approximately 91% of our share of annualized rental obligations from predominantly premier workplaces located in CBDs. We define annualized rental obligations as the monthly contractual base rent (excluding percentage rent and rent abatements) and budgeted reimbursements from clients under existing leases as of June 30, 2026, multiplied by twelve. Our share of annualized rental obligations is calculated as the consolidated amount, plus our share of the amount from our unconsolidated joint ventures (calculated based on our economic percentage ownership interest), less our partners’ share of the amount from our consolidated joint ventures (calculated based on the partners’ economic percentage ownership interest). As of June 30, 2026, our CBD assets were 90.7% occupied and 93.6% leased (including vacant space for which we have signed leases that have not yet commenced in accordance with GAAP).

Our progress reflects steady advancement across these key priorities.

Previous wording

Leasing conditions across BXP's portfolio remain constructive, supported by continued demand for premier office assets and improving leasing execution. Activity is increasingly concentrated in BXP’s premier office locations, including Midtown Manhattan, Boston's Back Bay, Reston Town Center, and select San Francisco submarkets, where tightening availability and improving demand are contributing to leasing momentum. At the same time, discussion surrounding the impact of artificial intelligence on office-using employment has become more balanced and constructive, contributing to a more favorable demand backdrop. Collectively, these trends support BXP's view that premier workplaces in gateway markets remain well-positioned to capture evolving tenant demand.

Previous wording

Looking ahead, leasing for vacant space in our in-service buildings and coverage of near‑term lease expirations are expected to be the primary drivers of occupancy and revenue growth in our same property portfolio. We have a modest 300,000 square feet of leases expiring prior to December 31, 2026, a strong pipeline of active negotiations, and a meaningful volume totaling 1.1 million square feet of executed leases scheduled to commence this year.

Current wording

Looking ahead, we expect the leasing of vacant space in our in-service buildings and covering near-term lease expirations to remain important drivers of occupancy and revenue growth in our same property portfolio. We have approximately 186,000 square feet of leases expiring during the remainder of 2026 and approximately 600,000 square feet of currently vacant space that is leased and expected to commence during the fourth quarter of 2026.

Previous wording

In the second quarter of 2026, we executed 106 leases totaling approximately 1.8 million square feet with a weighted-average lease term of approximately 9.9 years.

As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data with respect to the Total Property Portfolio provides a complete understanding of our operating results. Therefore, the comparison of operating results for the three and six months ended June 30, 2026 and 2025 shows separately the changes attributable to the properties that were owned by us and in-service throughout each period compared (the “Same Property Portfolio”) and the changes attributable to the properties included in the Acquired, Placed In-Service, In or Held for Development or Redevelopment or Sold Portfolios.

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, loss from early extinguishment of debt, impairment loss, loss on sales-type lease, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) unrealized gain (loss) on non-real estate investments, gains from investments in securities, interest and other income (loss), gains on sales of real estate, income (loss) from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. We use NOI internally as a performance measure and believe it provides useful information to investors regarding our results of operations and financial condition because, when compared across periods, it reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income 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.
