2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation

On an ongoing basis, as circumstances indicate the need for reconsideration, we evaluate each legal entity that is not wholly

owned by us in accordance with the consolidation accounting guidance. Our evaluation considers all of our variable interests, including

equity ownership, as well as fees paid to us for our involvement in the management of each partially owned entity. To fall within the

scope of the consolidation guidance, an entity must meet both of the following criteria:

•The entity has a legal structure that has been established to conduct business activities and to hold assets; such entity

can be in the form of a partnership, limited liability company, or corporation, among others; and

•We have a variable interest in the legal entity — i.e., variable interests that are contractual, such as equity ownership, or

other financial interests that change with changes in the fair value of the entity’s net assets.

If an entity does not meet both criteria above, we apply other accounting literature, such as the equity method of accounting. If

an entity does meet both criteria above, we evaluate such entity for consolidation under either the variable interest model if the legal

entity meets any of the characteristics below to qualify as a VIE, or under the voting model for all other legal entities that are not VIEs.

A legal entity is determined to be a VIE if it has any of the following three characteristics:

1)The entity does not have sufficient equity to finance its activities without additional subordinated financial support;

2)The entity is established with non-substantive voting rights (i.e., the entity deprives the majority economic interest

holder(s) of voting rights); or

3)The equity holders, as a group, lack the characteristics of a controlling financial interest. Equity holders meet this criterion

if they lack any of the following:

•The power, through voting rights or similar rights, to direct the activities of the entity that most significantly influence

the entity’s economic performance, as evidenced by:

•Substantive participating rights in day-to-day management of the entity’s activities; or

•Substantive kick-out rights over the party responsible for significant decisions;

•The obligation to absorb the entity’s expected losses; or

•The right to receive the entity’s expected residual returns.

For an entity, including our real estate joint ventures, structured as a limited partnership or a limited liability company, our

evaluation of whether the equity holders (equity partners other than the general partner or the managing member of a joint venture) lack

the characteristics of a controlling financial interest includes the evaluation of whether the limited partners or non-managing members

(the noncontrolling equity holders) lack both substantive participating rights and substantive kick-out rights, defined as follows:

•Participating rights provide the noncontrolling equity holders the ability to direct significant financial and operating

decisions made in the ordinary course of business that most significantly influence the entity’s economic performance.

•Kick-out rights allow the noncontrolling equity holders to remove the general partner or managing member without cause.

If we conclude that any of the three characteristics of a VIE is met, including that the equity holders lack the characteristics of a

controlling financial interest because they lack both substantive participating rights and substantive kick-out rights, we conclude that the

entity is a VIE and evaluate it for consolidation under the variable interest model.

Variable interest model

If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is

a qualitative analysis based on power and benefits. We consolidate a VIE if we have both power and benefits — that is, (i) we have the

power to direct the activities of a VIE that most significantly influence the VIE’s economic performance (power) and (ii) we have the

obligation to absorb losses of or the right to receive benefits from the VIE that could potentially be significant to the VIE (benefits). We

consolidate VIEs whenever we determine that we are the primary beneficiary. Refer to Note 4 – “Consolidated and unconsolidated real

estate joint ventures” and Note 7 – “Investments” to our unaudited consolidated financial statements for information on specific entities

that qualify as VIEs. If we have a variable interest in a VIE but are not the primary beneficiary, we account for our investment using the

equity method.

Voting model

If a legal entity fails to meet any of the three characteristics of a VIE (i.e., insufficiency of equity, existence of non-substantive

voting rights, or lack of a controlling financial interest), we then evaluate such entity under the voting model. Under the voting model, we

consolidate the entity if we determine that we, directly or indirectly, have greater than 50% of the voting shares (or own a majority of the

limited partnership’s kick-out rights through voting interests), and that other equity holders do not have substantive participating rights.

Refer to Note 4 – “Consolidated and unconsolidated real estate joint ventures” to our unaudited consolidated financial statements for

information on specific real estate joint ventures that qualify for evaluation under the voting model.

Noncontrolling interests in consolidated real estate joint ventures

Noncontrolling interests represent the third-party interests in consolidated real estate joint ventures in which we have a

controlling interest. Certain of our partners’ noncontrolling interests have the right to require us to redeem their ownership interests in

the respective entities. We classify the ownership interests in these entities as redeemable noncontrolling interests outside of total

equity in our consolidated balance sheets. Redeemable noncontrolling interests are adjusted for additional contributions and

distributions, the proportionate share of net earnings or losses, and other comprehensive income or loss. If the amount of a redeemable

noncontrolling interest is less than the maximum redemption value at the balance sheet date, such amount is adjusted to the maximum

redemption value. Subsequent declines in the redemption value are recognized only to the extent that previous increases have been

recognized.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions

that affect the reported amounts of assets, liabilities, and equity; the disclosure of contingent assets and liabilities as of the date of the

consolidated financial statements; and the amounts of revenues and expenses during the reporting period. Actual results could

materially differ from those estimates.

Evaluation of business combination or asset acquisition

We evaluate each acquisition of real estate or in-substance real estate (including equity interests in entities that predominantly

hold real estate assets) to determine whether the integrated set of assets and activities acquired meets the definition of a business and

must be accounted for as a business combination. An acquisition of an integrated set of assets and activities that does not meet the

definition of a business is accounted for as an asset acquisition. If either of the following criteria is met, the integrated set of assets and

activities acquired would not qualify as a business:

•Substantially all of the fair value of the gross assets acquired is concentrated in either a single identifiable asset or a group

of similar identifiable assets; or

•The integrated set of assets and activities is lacking, at a minimum, an input and a substantive process that together

significantly contribute to the ability to create outputs (i.e., revenue generated before and after the transaction).

An acquired process is considered substantive if:

•The process includes an organized workforce (or includes an acquired contract that provides access to an organized

workforce) that is skilled, knowledgeable, and experienced in performing the process;

•The process cannot be replaced without significant cost, effort, or delay; or

•The process is considered unique or scarce.

Generally, our acquisitions of real estate or in-substance real estate do not meet the definition of a business because

substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e., land, buildings,

and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or

an acquired contract that cannot be replaced without significant cost, effort, or delay. When evaluating acquired service or management

contracts, we consider the nature of the services performed, the terms of the contract relative to similar arm’s-length contracts, and the

availability of comparable vendors in evaluating whether the acquired contract constitutes a substantive process.

Recognition of real estate acquired

We evaluate each acquisition of real estate or in-substance real estate (including equity interests in entities that predominantly

hold real estate assets) to determine whether the integrated set of assets and activities acquired meets the definition of a business and

must be accounted for as a business combination. An acquisition of an integrated set of assets and activities that does not meet the

definition of a business is accounted for as an asset acquisition.

For acquisitions of real estate or in-substance real estate that are accounted for as business combinations, we allocate the

acquisition consideration (excluding acquisition costs) to the assets acquired, liabilities assumed, noncontrolling interests, and

previously existing ownership interests at fair value as of the acquisition date. Assets include intangible assets such as tenant

relationships, acquired in-place leases, and favorable intangibles associated with in-place leases in which we are the lessor. Liabilities

include unfavorable intangibles associated with in-place leases in which we are the lessor. In addition, for acquired in-place finance or

operating leases in which we are the lessee, acquisition consideration is allocated to lease liabilities and related right-of-use assets,

adjusted to reflect favorable or unfavorable terms of the lease when compared with market terms. Any excess (deficit) of the

consideration transferred relative to the fair value of the net assets acquired is accounted for as goodwill (bargain purchase gain).

Acquisition costs related to business combinations are expensed as incurred.

Generally, we expect that acquisitions of real estate or in-substance real estate will not meet the definition of a business

because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e., land,

buildings, and related intangible assets). The accounting model for asset acquisitions is similar to the accounting model for business

combinations, except that the acquisition consideration (including acquisition costs) is allocated to the individual assets acquired and

liabilities assumed on a relative fair value basis. Any excess (deficit) of the consideration transferred relative to the sum of the fair value

of the assets acquired and liabilities assumed is allocated to the individual assets and liabilities based on their relative fair values. As a

result, asset acquisitions do not result in the recognition of goodwill or a bargain purchase gain. Incremental and external direct

acquisition costs related to acquisitions of real estate or in-substance real estate (such as legal and other third-party services) are

capitalized.

We exercise judgment to determine the key assumptions used to allocate the purchase price of real estate acquired among its

components. The allocation of the consideration to the various components of properties acquired during the year can have an effect on

our net income due to the useful depreciable and amortizable lives applicable to each component and the recognition of the related

depreciation and amortization expense in our consolidated statements of operations. We apply judgment in utilizing available

comparable market information to assess relative fair value. We assess the relative fair values of tangible and intangible assets and

liabilities based on available comparable market information, including estimated replacement costs, rental rates, and recent market

transactions. In addition, we may use estimated cash flow projections that utilize appropriate discount and capitalization rates.

Estimates of future cash flows are based on a number of factors, including the historical operating results, known and anticipated

trends, and market/economic conditions that may affect the property.

The value of tangible assets acquired is based upon our estimation of fair value on an “as if vacant” basis. The value of

acquired in-place leases includes the estimated costs during the hypothetical lease-up period and other costs that would have been

incurred in the execution of similar leases under the market conditions at the acquisition date of the acquired in-place lease. If there is a

bargain fixed-rate renewal option for the period beyond the noncancelable lease term of an in-place lease, we evaluate intangible

factors, such as the business conditions in the industry in which the lessee operates, the economic conditions in the area in which the

property is located, and the ability of the lessee to sublease the property during the renewal term, in order to determine the likelihood

that the lessee will renew. When we determine that the lessee is reasonably certain to exercise such bargain renewal option, we

consider the option in determining the intangible value of such lease and its related amortization period. We also recognize the relative

fair values of assets acquired, the liabilities assumed, and any noncontrolling interest in acquisitions of less than a 100% interest when

the acquisition constitutes a change in control of the acquired entity.

The values allocated to buildings and building improvements, land improvements, tenant improvements, and equipment are

depreciated on a straight-line basis. For buildings and building improvements, we depreciate using the shorter of the respective ground

lease terms or their estimated useful lives, not to exceed 40 years. Land improvements are depreciated over their estimated useful

lives, not to exceed 20 years. Tenant improvements are depreciated over their respective lease terms or estimated useful lives, and

equipment is depreciated over the shorter of the lease term or its estimated useful life. Right-of-use assets are amortized on a straight-

line basis over the remaining terms of each related lease. The values of acquired in-place leases and associated favorable intangibles

(i.e., acquired above-market leases) are classified in other assets in our consolidated balance sheets and are amortized over the

remaining terms of the related leases as a reduction of income from rentals in our consolidated statements of operations. The values of

unfavorable intangibles (i.e., acquired below-market leases) associated with acquired in-place leases are classified in accounts

payable, accrued expenses, and other liabilities in our consolidated balance sheets and are amortized over the remaining terms of the

related leases as an increase in income from rentals in our consolidated statements of operations.

Capitalized project costs

We capitalize project costs, including pre-construction costs, interest, property taxes, insurance, and other costs directly

related and essential to the development, redevelopment, pre-construction, or construction of a project. Capitalization of development,

redevelopment, pre-construction, and construction costs is required while activities are ongoing to prepare an asset for its intended use.

Fluctuations in our development, redevelopment, pre-construction, and construction activities could result in significant changes to total

expenses and net income. Costs incurred after a project is substantially complete and ready for its intended use are expensed as

incurred. Should development, redevelopment, pre-construction, or construction activity cease, interest, property taxes, insurance, and

certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and

maintenance are expensed as incurred.

Real estate sales

A property is classified as held for sale when all of the following criteria for a plan of sale have been met: (i) management,

having the authority to approve the action, commits to a plan to sell the property; (ii) the property is available for immediate sale in its

present condition, subject only to terms that are usual and customary; (iii) an active program to locate a buyer and other actions

required to complete the plan to sell have been initiated; (iv) the sale of the property is probable and is expected to be completed within

one year; (v) the property is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and

(vi) actions necessary to complete the plan of sale indicate that it is unlikely that significant changes to the plan will be made or that the

plan will be withdrawn. Depreciation of assets ceases upon designation of a property as held for sale.

If the disposal of a property represents a strategic shift that has (or will have) a major effect on our operations or financial

results, such as (i) a major line of business, (ii) a major geographic area, (iii) a major equity method investment, or (iv) other major parts

of an entity, then the operations of the property, including any interest expense directly attributable to it, are classified as discontinued

operations in our consolidated statements of operations, and amounts for all prior periods presented are reclassified from continuing

operations to discontinued operations. The disposal of an individual property generally will not represent a strategic shift and therefore

will typically not meet the criteria for classification as a discontinued operation.

We recognize gains or losses on real estate sales in accordance with the accounting standard on the derecognition of

nonfinancial assets arising from contracts with noncustomers. Our ordinary output activities consist of the leasing of space to our

tenants in our operating properties, not the sales of real estate. Therefore, sales of real estate (in which we are the seller) qualify as

contracts with noncustomers. In our transactions with noncustomers, we apply certain recognition and measurement principles

consistent with our method of recognizing revenue arising from contracts with customers. Derecognition of the asset is based on the

transfer of control. If a real estate sales contract includes our ongoing involvement with the property, then we evaluate each promised

good or service under the contract to determine whether it represents a separate performance obligation, constitutes a guarantee, or

prevents the transfer of control. If a good or service is considered a separate performance obligation, an allocated portion of the

transaction price is recognized as revenue as we transfer the related good or service to the buyer.

The recognition of gain or loss on the sale of a partial interest also depends on whether we retain a controlling or

noncontrolling interest in the property. If we retain a controlling interest in the property upon completion of the sale, we continue to

reflect the asset at its book value, record a noncontrolling interest for the book value of the partial interest sold, and recognize additional

paid-in capital for the difference between the consideration received and the partial interest at book value. Conversely, if we retain a

noncontrolling interest upon completion of the sale of a partial interest of real estate, we recognize a gain or loss as if 100% of the asset

were sold.

Impairment of long-lived assets

Prior to and subsequent to the end of each quarter, we review current activities and changes in the business conditions of all of

our long-lived assets to determine the existence of any triggering events or impairment indicators requiring an impairment analysis. If

triggering events or impairment indicators are identified, we review an estimate of the future undiscounted cash flows, including, if

necessary, a probability-weighted approach if multiple outcomes are under consideration.

Long-lived assets to be held and used, including our rental properties, CIP, land held for development, right-of-use assets

related to operating leases in which we are the lessee, and intangibles, are individually evaluated for impairment when conditions exist

that may indicate that the carrying amount of a long-lived asset may not be recoverable. The carrying amount of a long-lived asset to be

held and used is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual

disposition of the asset. Triggering events or impairment indicators for long-lived assets to be held and used are assessed by project

and include significant fluctuations in estimated net operating income, occupancy changes, significant near-term lease expirations,

current and historical operating and/or cash flow losses, construction costs, estimated completion dates, rental rates, and other market

factors. We assess the expected undiscounted cash flows based upon numerous factors, including, but not limited to, projected rental

rates, estimated exit capitalization rates, and anticipated construction costs for projects under construction, which are based on

available market information, current and historical operating results, known trends, current market/economic conditions that may affect

the asset, and our assumptions about the use of the asset, including, if necessary, a probability-weighted approach if multiple outcomes

are under consideration.

Upon determination that an impairment has occurred, a write-down is recognized to reduce the carrying amount of the asset to

its estimated fair value. If an impairment charge is not required to be recognized, the recognition of depreciation or amortization is

adjusted prospectively, as necessary, to reduce the carrying amount of the asset to its estimated disposition value over the remaining

period that the asset is expected to be held and used. We may adjust depreciation of properties that are expected to be disposed of or

redeveloped prior to the end of their useful lives.

We use the held for sale impairment model for our properties classified as held for sale, which is different from the held and

used impairment model. Under the held for sale impairment model, an impairment charge is recognized if the carrying amount of the

long-lived asset classified as held for sale exceeds its fair value less cost to sell. Because of these two different models, it is possible for

a long-lived asset previously classified as held and used to require the recognition of an impairment charge upon classification as held

for sale.

International operations

As of September 30, 2026, in addition to operating properties in the U.S., we had 11 properties in Canada. The functional

currency for our subsidiaries operating in the U.S. is the U.S. dollar. The local currency of a foreign subsidiary serves as its functional

currency. The assets and liabilities of our foreign subsidiaries are translated into U.S. dollars at the exchange rate in effect as of the

financial statement date. Revenue and expense accounts of our foreign subsidiaries are translated using the weighted-average

exchange rate for the periods presented. Gains or losses resulting from the translation are classified in accumulated other

comprehensive income (loss) as a separate component of total equity and are excluded from net income (loss).

Whenever a foreign investment meets the criteria for classification as held for sale, we evaluate the recoverability of the

investment under the held for sale impairment model. We may recognize an impairment charge if the carrying amount of the investment

exceeds its fair value less cost to sell. In determining an investment’s carrying amount, we consider its net book value and any

cumulative unrealized foreign currency translation adjustment related to the investment. The appropriate amounts of foreign exchange

rate gains or losses classified in accumulated other comprehensive income (loss) are reclassified to net income (loss) when realized

upon the sale of our investment or upon the complete or substantially complete liquidation of our investment.

We hold investments in publicly traded companies and privately held entities primarily involved in the life science industry. As a

REIT, we generally limit our ownership of each individual entity’s voting stock to less than 10%. We evaluate each investment to

determine whether we have the ability to exercise significant influence, but not control, over an investee. We evaluate investments in

which our ownership is equal to or greater than 20%, but less than or equal to 50%, of an investee’s voting stock with a presumption

that we have this ability. For our investments in limited partnerships that maintain specific ownership accounts, we presume that such

ability exists when our ownership interest exceeds 3% to 5%. In addition to our ownership interest, we consider whether we have a

board seat or whether we participate in the investee’s policy-making process, among other criteria, to determine if we have the ability to

exert significant influence, but not control, over an investee. If we determine that we have such ability, we account for the investment

under the equity method, as described below. From time to time, we may hold equity investments in publicly traded companies that are

subject to temporary contractual sale restrictions. We do not recognize a discount related to a contractual sale restriction.

Investments accounted for under the equity method

Under the equity method of accounting, we initially recognize our investment at cost and subsequently adjust the carrying

amount of the investment for our share of earnings or losses reported by the investee, distributions received, and other-than-temporary

impairments. For additional information about our investments accounted for under the equity method, refer to Note 7 – “Investments” to

our unaudited consolidated financial statements.

Investments that do not qualify for the equity method of accounting

For investees over which we determine that we do not have the ability to exercise significant influence or control, we account

for each investment depending on whether it is an investment in a (i) publicly traded company, (ii) privately held entity that reports NAV

per share, or (iii) privately held entity that does not report NAV per share, as described below.

Investments in publicly traded companies

Our investments in publicly traded companies are classified as investments with readily determinable fair values and are

presented at fair value in our consolidated balance sheets, with changes in fair value classified in investment income (losses) in our

consolidated statements of operations. The fair values for our investments in publicly traded companies are determined based on sales

prices or quotes available on securities exchanges.

Investments in privately held companies

Our investments in privately held entities without readily determinable fair values consist of (i) investments in privately held

entities that report NAV per share and (ii) investments in privately held entities that do not report NAV per share. These investments are

accounted for as follows:

Investments in privately held entities that report NAV per share

Investments in privately held entities that report NAV per share, such as our privately held investments in limited partnerships,

are presented at fair value using NAV as a practical expedient, with changes in fair value classified in investment income (losses) in our

consolidated statements of operations. We use NAV per share reported by limited partnerships generally without adjustment, unless we

are aware of information indicating that the NAV reported by a limited partnership does not accurately reflect the fair value of the

investment at our reporting date.

Investments in privately held entities that do not report NAV per share

Investments in privately held entities that do not report NAV per share are accounted for using a measurement alternative

under which these investments are measured at cost, adjusted for observable price changes and impairments, with changes classified

in investment income (losses) in our consolidated statements of operations.

An observable price arises from an orderly transaction for an identical or similar investment of the same issuer, which is

observed by an investor without expending undue cost and effort. Observable price changes result from, among other things, equity

transactions of the same issuer executed during the reporting period, including subsequent equity offerings or other reported equity

transactions related to the same issuer. To determine whether these transactions are indicative of an observable price change, we

evaluate, among other factors, whether these transactions have similar rights and obligations, including voting rights, distribution

preferences, and conversion rights to the investments we hold.

Impairment evaluation of equity method investments and investments in privately held entities that do not report NAV per share

We monitor equity method investments and investments in privately held entities that do not report NAV per share for new

developments, including operating results, prospects and results of clinical trials, new product initiatives, new collaborative agreements,

capital-raising events, and merger and acquisition activities. These investments are evaluated on the basis of a qualitative assessment

for indicators of impairment by monitoring the presence of the following triggering events or impairment indicators:

(i)a significant deterioration in the earnings performance, credit rating, asset quality, or business prospects of the investee;

(ii)a significant adverse change in the regulatory, economic, or technological environment of the investee;

(iii)a significant adverse change in the general market condition, including the research and development of technology and

products that the investee is bringing or attempting to bring to the market;

(iv)significant concerns about the investee’s ability to continue as a going concern; and/or

(v)a decision by investors to cease providing support or reduce their financial commitment to the investee.

If such indicators are present, we are required to estimate the investment’s fair value and immediately recognize an

impairment charge in an amount equal to the investment’s carrying value in excess of its estimated fair value.

Investment income/loss recognition and classification

We recognize both realized and unrealized gains and losses in our consolidated statements of operations, classified in

investment income (losses) in our consolidated statements of operations. Unrealized gains and losses represent:

(i)changes in fair value for investments in publicly traded companies;

(ii)changes in NAV for investments in privately held entities that report NAV per share;

(iii)observable price changes for investments in privately held entities that do not report NAV per share; and

(iv)our share of unrealized gains or losses reported by our equity method investees.

Realized gains and losses on our investments represent the difference between proceeds received upon disposition of

investments and their historical or adjusted cost basis. For our equity method investments, realized gains and losses represent our

share of realized gains or losses reported by the investee. Impairments are realized losses, which result in an adjusted cost basis, and

represent charges to reduce the carrying values of investments in privately held entities that do not report NAV per share and equity

method investments, if impairments are deemed other than temporary, to their estimated fair value.

Revenues

The table below provides details of our consolidated total revenues for thethree and nine months ended September 30, 2026

and 2025 (in thousands):

During thethree and nine months ended September 30, 2026, revenues that were subject to the lease accounting standard

aggregated$642.2 million and$1.91 billion, respectively, and represented 95.7% and 95.5% of our total revenues. During thethree and

nine months ended September 30, 2025, revenues that were subject to the lease accounting standard aggregated$724.1 million and

$2.18 billion, respectively, and represented 96.3% and 96.0% of our total revenues. Our other income consisted primarily of

management and other fees and interest income earned during each period presented. For a detailed discussion related to our revenue

streams, refer to “Lease accounting” and “Recognition of revenue arising from contracts with customers” in Note 2 – “Summary of

Lease accounting

Definition and classification of a lease

When we enter into a contract or amend an existing contract, we evaluate whether the contract meets the definition of a lease.

To meet the definition of a lease, the contract must meet all three criteria:

(i)One party (lessor) must hold an identified asset;

(ii)The counterparty (lessee) must have the right to obtain substantially all of the economic benefits from the use of the asset

throughout the period of the contract; and

(iii)The counterparty (lessee) must have the right to direct the use of the identified asset throughout the period of the contract.

We classify our leases as either finance leases or operating leases if we are the lessee, or sales-type, direct financing, or

operating leases if we are the lessor. We use the following criteria to determine if a lease is a finance lease (as a lessee) or sales-type

or direct financing lease (as a lessor):

(i)Ownership is transferred from lessor to lessee by the end of the lease term;

(ii)An option to purchase is reasonably certain to be exercised;

(iii)The lease term is for the major part of the underlying asset’s remaining economic life;

(iv)The present value of lease payments equals or exceeds substantially all of the fair value of the underlying asset; or

(v)The underlying asset is specialized and is expected to have no alternative use at the end of the lease term.

If a lease meets any of the above criteria, we account for it as a finance, a sales-type, or a direct financing lease. If a lease

does not meet any of the criteria, we account for it as an operating lease.

A lease is accounted for as a sales-type lease if it is considered to transfer control of the underlying asset to the lessee. A

lease is accounted for as a direct financing lease if risks and rewards are conveyed without the transfer of control, which is normally

indicated by the existence of a residual value guarantee from an unrelated third party other than the lessee.

This classification will determine the method of recognition of the lease:

•For an operating lease, we recognize income from rentals if we are the lessor, or rental operations expense if we are the

lessee, over the term of the lease on a straight-line basis.

•For a sales-type lease or a direct financing lease, we recognize the income from rentals, or for a finance lease, we

recognize rental operations expense, over the term of the lease using the effective interest method.

•At inception of a sales-type lease or a direct financing lease, if we determine the fair value of the leased property is lower

than its carrying amount, we recognize a selling loss immediately at lease commencement. If fair value exceeds the

carrying amount of a lease, a gain is recognized at lease commencement on a sales-type lease. For a direct financing

lease, a gain is deferred at lease commencement and amortized over the lease term.

Lessor accounting

Costs to execute leases

We capitalize initial direct costs, which represent only incremental costs to execute a lease that would not have been incurred

if the lease had not been obtained. Costs that we incur to negotiate or arrange a lease, regardless of its outcome, such as for fixed

employee compensation, tax or legal advice to negotiate lease terms, and other costs, are expensed as incurred.

Operating leases

We account for the revenue from our lease contracts by utilizing the single component accounting policy. This policy requires

us to account for, by class of underlying asset, the lease component and nonlease component(s) associated with each lease as a single

component if two criteria are met:

(i)The timing and pattern of transfer of the lease component and the nonlease component(s) are the same; and

(ii)The lease component would be classified as an operating lease if it were accounted for separately.

Lease components consist primarily of fixed rental payments, which represent scheduled rental amounts due under our

leases, and contingent rental payments. Nonlease components consist primarily of tenant recoveries representing reimbursements of

rental operating expenses under our triple net lease structure, including recoveries for property taxes, insurance, utilities, repairs and

maintenance, and common area expenses.

If the lease component is the predominant component, we account for all revenues under such lease as a single component in

accordance with the lease accounting standard. Conversely, if the nonlease component is the predominant component, all revenues

under such lease are accounted for in accordance with the revenue recognition accounting standard. Our operating leases qualify for

the single component accounting, and the lease component in each of our leases is predominant. Therefore, we account for all

revenues from our operating leases under the lease accounting standard and classify these revenues as income from rentals in our

consolidated statements of operations.

We commence recognition of income from rentals related to the operating leases at the date the property is ready for its

intended use by the tenant and the tenant takes possession or controls the physical use of the leased asset. When a lease includes

construction of improvements, we determine whether the improvements are landlord or tenant assets. In determining if the

improvements are landlord or tenant improvements, we consider various factors, including, but not limited to, the following:

•Which party retains legal title to the improvements upon lease expiration;

•Whether the improvements are expected to have significant residual value at the end of the lease term;

•Whether the improvements are unique to the tenant;

•What happens to the improvements upon lease expiration (i.e., whether they are removed or preserved for the landlord);

•Which party bears all costs of the improvements (including the risk of cost overruns); and

•Which party supervises the construction of the improvements.

If the improvements are landlord assets, we capitalize such improvements. If the improvements are tenant assets, we do not

capitalize these assets. Improvements that qualify as tenant assets, if funded by us, are accounted for as lease incentives and

amortized as a reduction of revenue over the term of the lease. If the tenant funds improvements without reimbursement from us, and

we determine these improvements to be landlord assets, we consider the amount associated with the improvements to be non-cash

lease payments, which are recognized as incremental revenue over the term of the related lease.

Income from rentals related to fixed rental payments under operating leases is recognized on a straight-line basis over the

respective operating lease terms. We classify amounts expected to be received in later periods as deferred rent in our consolidated

balance sheets. Amounts received currently but recognized as revenue in future periods are classified in accounts payable, accrued

expenses, and other liabilities in our consolidated balance sheets.

Income from rentals related to variable payments includes tenant recoveries and contingent rental payments. Tenant

recoveries, including reimbursements of utilities, repairs and maintenance, common area expenses, real estate taxes and insurance,

and other operating expenses, are recognized as revenue in the period during which the applicable expenses are incurred and the

tenant’s obligation to reimburse us arises. Income from rentals related to other variable payments is recognized when associated

contingencies are removed.

We assess collectibility of future lease payments from our tenants for each of our operating leases. If we determine that

collectibility is probable, we recognize income from rentals based on the methodology described above. If we determine that

collectibility is not probable, we recognize an adjustment to lower our income from rentals. Furthermore, we may recognize a general

allowance at a portfolio level (not the individual level) if we do not expect to collect future lease payments in full.

For each lease for which we determine that collectibility of future lease payments is not probable, we cease the recognition of

income from rentals on a straight-line basis and limit the recognition of income to the lesser of payments collected from the lessee or

lease income that would have been recognized on a straight-line basis. We do not resume straight-line recognition of income from

rentals for these leases until we determine that the collectibility of future payments related to these leases is probable. We also record a

general allowance related to the deferred rent balances that at the portfolio level (not the individual level) are not expected to be

collected in full through the lease term. As of September 30, 2026 and December 31, 2025, ourgeneral allowance balance aggregated

$27.0 million and$14.3 million, respectively.

Direct financing and sales-type leases

Income from rentals related to direct financing and sales-type leases is recognized over the lease term using the effective

interest rate method. At lease commencement, we derecognize the underlying asset classified within investments in real estate and

record net investment in a lease within other assets in our consolidated balance sheets. This initial net investment is determined by

aggregating the present values of the total future lease payments and the estimated residual value of the property, less any unearned

income related to a direct financing lease. Over the lease term, the investment in the lease accretes in value, producing a constant

periodic rate of return on the net investment in the lease. Income from these leases is classified in income from rentals in our

consolidated statements of operations. Lease payments received reduce the net investment in the lease.

We evaluate our net investment in direct financing and sales-type leases for impairment under the current expected credit

losses accounting standard. For additional information, refer to “Provision for expected credit losses” in Note 2 – “Summary of

As a lessor, we classify a lease with variable lease payments that do not depend on an index or a rate as an operating lease

on the commencement date of the lease if both of the following criteria are met:

(i)The lease would have been classified as a sales-type lease or direct financing lease under the current lease accounting

standard; and

(ii)The sales-type lease or direct financing lease classification would have resulted in a selling loss at lease commencement.

We do not derecognize the underlying asset and do not recognize a loss upon lease commencement but continue to

depreciate the underlying asset over its useful life.

Lessee accounting

We have operating lease agreements in which we are the lessee consisting of ground and office leases. At the lease

commencement date (or at the acquisition date if the lease is acquired as part of a real estate acquisition), we are required to recognize

a liability to account for our future obligations under these operating leases, and a corresponding right-of-use asset.

The lease liability is measured based on the present value of the future lease payments, including payments during the term

under our extension options that we are reasonably certain to exercise. The present value of the future lease payments is calculated for

each operating lease using each respective remaining lease term and a corresponding estimated incremental borrowing rate, which is

the interest rate that we estimate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to

the lease payments. Subsequently, the lease liability is accreted by applying a discount rate established at the lease commencement

date to the lease liability balance as of the beginning of the period and is reduced by the payments made during the period. We classify

the operating lease liability in accounts payable, accrued expenses, and other liabilities in our consolidated balance sheets.

The right-of-use asset is measured based on the corresponding lease liability, adjusted for initial direct leasing costs and any

other consideration exchanged with the landlord prior to the commencement of the lease, as well as adjustments to reflect favorable or

unfavorable terms of an acquired lease when compared with market terms at the time of acquisition. Subsequently, the right-of-use

asset is amortized on a straight-line basis during the lease term. We classify the right-of-use asset in other assets in our consolidated

balance sheets.

Recognition of revenue arising from contracts with customers

We recognize revenues associated with transactions arising from contracts with customers, excluding revenues subject to the

lease accounting standard discussed in “Lease accounting” above, in accordance with the revenue recognition accounting standard. A

customer is distinguished from a noncustomer by the nature of the goods or services that are transferred. Customers are provided with

goods or services that are generated by a company’s ordinary output activities, whereas noncustomers are provided with nonfinancial

assets that are outside of a company’s ordinary output activities.

We generally recognize revenue representing the transfer of goods and services to customers in an amount that reflects the

consideration to which we expect to be entitled in the exchange. In order to determine the recognition of revenue from customer

contracts, we use a five-step model to (i) identify the contract with the customer, (ii) identify the performance obligations in the contract,

(iii) determine the transaction price, including variable consideration to the extent that it is probable that a significant future reversal will

not occur, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) we

satisfy the performance obligation.

We identify contractual performance obligations and determine whether revenue should be recognized at a point in time or

over time, based on when control of goods and services transfers to a customer. We consider whether we control the goods or services

prior to the transfer to the customer in order to determine whether we should account for the arrangement as a principal or agent. If we

determine that we control the goods or services provided to the customer, then we are the principal to the transaction, and we recognize

the gross amount of consideration expected in the exchange. If we simply arrange but do not control the goods or services being

transferred to the customer, then we are considered to be an agent to the transaction, and we recognize the net amount of

consideration we are entitled to retain in the exchange.

Total revenues subject to the revenue recognition accounting standard and classified within income from rentals in our

consolidated statements of operations for thethree and nine months ended September 30, 2026 included $11.4 million and$35.7

million, respectively, primarily related to short-term parking revenues associated with long-term lease agreements. Short-term parking

revenues do not qualify for the single component accounting policy, as discussed in “Lessor accounting” in Note 2 – “Summary of

significant accounting policies,” due to the difference in the timing and pattern of transfer of our parking service obligations and

associated lease components within the same lease agreement. We recognize short-term parking revenues in accordance with the

revenue recognition accounting standard when the service is provided and the performance obligation is satisfied, which normally

occurs at a point in time.

Monitoring of tenant credit quality

During the term of each lease, we monitor the credit quality and any related material changes of our tenants by (i) monitoring

the credit rating of tenants that are rated by a nationally recognized credit rating agency, (ii) reviewing financial statements of the

tenants that are publicly available or that are required to be delivered to us pursuant to the applicable lease, (iii) monitoring news

reports regarding our tenants and their respective businesses, and (iv) monitoring the timeliness of lease payments.

Notes receivable

We carry notes receivable at amortized cost, adjusted for an estimated provision for expected credit losses. Interest income on

notes receivable is recognized using the effective interest rate method and is classified within other income in our consolidated

statements of operations. Direct costs incurred in originating notes, along with any premium or discount, are deferred and amortized as

an adjustment to interest income over the note’s term using the effective interest rate method. Notes receivable are classified within

other assets in our consolidated balance sheets. Refer to Note 8 – “Other assets” to our unaudited consolidated financial statements for

Provision for expected credit losses

We are required to estimate and recognize lifetime expected losses, rather than incurred losses, for most financial assets

measured at amortized cost and certain other instruments, including trade, notes, and other receivables (excluding receivables arising

from operating leases), loans, held-to-maturity debt securities, net investments in leases arising from sales-type and direct financing

leases, and off-balance-sheet credit exposures (e.g., loan commitments). The recognition of such expected losses, even if the expected

risk of credit loss is remote, typically results in earlier recognition of credit losses. At each reporting date, we reassess our provision for

expected credit losses, and, if necessary, we recognize an adjustment for our current estimate of expected credit losses. Refer to

Note 5 – “Leases” and Note 8 – “Other assets” to our unaudited consolidated financial statements for additional details.

An assessment of the collectibility of operating lease payments and the recognition of an adjustment to lease income based on

this assessment is governed by the lease accounting standard discussed in “Lease accounting” earlier in Note 2 — “Summary of

Income taxes

We are organized and operate as a REIT pursuant to the Internal Revenue Code (the “Code”). Under the Code, a REIT that

distributes at least 90% of its REIT taxable income to its stockholders annually (excluding net capital gains) and meets certain other

conditions is not subject to federal income tax on its distributed taxable income, but could be subject to certain federal, foreign, state,

and local taxes. We distribute 100% of our taxable income annually; therefore, a provision for federal income taxes is not required. In

addition to our REIT returns, we file federal, foreign, state, and local tax returns for our subsidiaries. We file with jurisdictions located in

the U.S., Canada, and other international locations. Our tax returns are subject to routine examination in various jurisdictions for the

2020 through 2025 calendar years.

Employee and non-employee share-based awards

We have implemented an entity-wide accounting policy to account for forfeitures related to unmet service conditions of share-

based awards granted to employees and non-employees when they occur. Under this policy, when forfeitures occur, any previously

recognized expense related to those forfeited awards is reversed in the period of forfeiture.

Our employee and non-employee share-based awards are measured at fair value on the grant date and recognized over the

recipient’s required service period. For share-based awards with performance conditions, we continue to assess the probability of

achieving the performance conditions and recognize expense only when it becomes probable that the performance targets will be met.

Conversely, for share-based awards with market conditions, expense is recognized regardless of whether the market condition is met.

Dividends paid on share-based awards with nonforfeitable dividends are initially classified in retained earnings and reclassified

to compensation cost only if the underlying awards are forfeited. Conversely, for share-based awards with forfeitable dividends,

declared dividends are initially classified in retained earnings and in dividends payable within our consolidated balance sheets. If the

underlying awards are forfeited, the corresponding accrued dividend is reversed in the period of forfeiture. Upon vesting of the

underlying share-based awards with forfeitable dividends, the accumulated dividend payment is made and the dividend payable liability

is settled.

Forward equity sales agreements

From time to time, we enter into forward equity sales agreements and account for them in accordance with the accounting

guidance governing financial instruments and derivatives. Under the accounting guidance, our forward equity sales agreements are

typically not deemed to be liabilities as they generally do not embody obligations to repurchase our shares, nor do they embody

obligations to issue a variable number of shares for which the monetary value is predominantly fixed, varied with something other than

the fair value of our shares, or varied inversely in relation to our shares. We also evaluate whether the agreements meet the derivatives

and hedging guidance scope exception to be accounted for as equity instruments. Our forward equity sales agreements are classified

as equity contracts based on the following assessment: (i) none of the agreements’ exercise contingencies are based on observable

markets or indices besides those related to the market for our own stock price and operations; and (ii) none of the settlement provisions

preclude the agreements from being indexed to our own stock.

Hedge accounting

From time to time, we utilize derivative instruments to manage our exposure to certain risks, including interest rate and foreign

currency exchange rate risks. We are exposed to foreign currency exchange rate risk related to our net investment in Canada. To

mitigate the impact of fluctuations in the USD-CAD exchange rate associated with our net investment in Canada, we use cross-currency

swap agreements designated and qualifying as net investment hedges under applicable derivatives and hedging standards.

We designate the USD-CAD cross-currency swap agreements as net investment hedges using the spot method to assess

hedge effectiveness. The spot component represents changes in fair value attributable to movements in the USD-CAD spot exchange

rate, which reflects the market exchange rate between the two currencies as of each reporting date. Changes in the fair value of the

designated spot component are recorded in other comprehensive income (loss) as part of the foreign currency translation adjustment,

to the extent the relationship is highly effective, until the net investment is sold or substantially liquidated. The related amounts due from

or due to counterparties are included in other assets or in accounts payable, accrued expenses, and other liabilities, respectively, within

our consolidated balance sheet.

We elected to account for the forward points (the portion of the derivative’s fair value attributable to the difference between the

forward exchange rate and spot exchange rate) as an excluded component in accordance with applicable derivatives and hedging

accounting standards. The excluded component is recognized over the life of the cross-currency swap agreements using a systematic

and rational basis (as interest settlements occur) and is classified within other income in our consolidated statement of operations.

Issuer and guarantor subsidiaries of guaranteed securities

Generally, a parent entity of an issuer that holds guaranteed securities must provide separate subsidiary issuer or guarantor

financial statements, unless it qualifies for disclosure exceptions. A parent entity may be eligible for disclosure exceptions if it meets the

following criteria:

(i)The subsidiary issuer or guarantor is a consolidated subsidiary of the parent company, and

(ii)The subsidiary issues a registered security that is:

•issued jointly and severally with the parent company, or

•fully and unconditionally guaranteed by the parent company.

A parent entity that meets the above criteria may instead present summarized financial information (“alternative disclosures”)

either within the consolidated financial statements or in “Item 2. Management’s discussion and analysis of financial condition and results

of operations” (“Item 2”). We evaluated the criteria and determined that we are eligible for the disclosure exceptions, which allow us to

provide alternative disclosures; as such, we present alternative disclosures in Item 2.

Loan fees

Fees incurred in obtaining long-term financing are capitalized and classified with the corresponding debt instrument appearing

on our consolidated balance sheets. Loan fees related to our unsecured senior line of credit are capitalized and classified within other

assets. Capitalized amounts are amortized over the term of the related loan, and the amortization is classified in interest expense in our

consolidated statements of operations.

Distributions from equity method investments

We use the “nature of the distribution” approach to determine the classification within our consolidated statements of cash

flows of cash distributions received from equity method investments, including our unconsolidated real estate joint ventures and equity

method non-real estate investments. Under this approach, distributions are classified based on the nature of the underlying activity that

generated the cash distributions. If we lack the information necessary to apply this approach in the future, we will be required to apply

the “cumulative earnings” approach as an accounting change on a retrospective basis. Under the cumulative earnings approach,

distributions up to the amount of cumulative equity in earnings recognized are classified as cash inflows from operating activities, and

those in excess of that amount are classified as cash inflows from investing activities.

Restricted cash

We present cash and cash equivalents separately from restricted cash within our consolidated balance sheets. However, we

include restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown

in the consolidated statements of cash flows. We provide a reconciliation between the consolidated balance sheets and the

consolidated statements of cash flows, which is required when the balance includes more than one line item for cash, cash equivalents,

and restricted cash. We also provide a disclosure of the nature of the restrictions related to material restricted cash balances.

Recent accounting pronouncements

On November 4, 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which will require

entities to provide enhanced disclosures related to certain expense categories included in line items on the statement of operations.

The ASU aims to increase transparency and provide investors with additional detailed information about the nature of expenses

reported on the face of the income statement. The new standard does not change the requirements for the presentation of expenses on

the face of the statement of operations.

Under this ASU, entities are required to disaggregate, in a tabular format, expense line items presented on the face of the

statement of operations — excluding earnings or losses from equity method investments — if they include any of the following expense

categories: employee compensation, depreciation, intangible asset amortization, depletion, and purchases of inventory. For any

remaining items within each relevant expense line item, entities must provide a qualitative description of the nature of those expenses.

The new ASU is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after

December 15, 2027. Early adoption is permitted. We expect to adopt this ASU on January 1, 2027. Although the adoption is not

expected to have an impact on our financial statements, it is expected to result in incremental disclosures within the notes to our

3. INVESTMENTS IN REAL ESTATE

Our consolidated investments in real estate consisted of the following as of September 30, 2026 and December 31, 2025 (in

(1)Refer to “Assets held for sale” below.

Assets held for sale

As of September 30, 2026, we had 18 operating properties and one development project aggregating 1.3 million RSF, and land

parcels aggregating 2.1 million SF that were classified as held for sale.

The disposal of the properties classified as held for sale does not represent a strategic shift that has, or will have, a major

effect on our operations or financial results, as the dispositions relate to an individual asset or a group of assets across multiple markets

and do not represent the exit from any significant market. Accordingly, these assets do not meet the criteria for classification as

discontinued operations. We cease depreciation of our properties upon their classification as held for sale.

The following table presents the components of net assets related to real estate investments that met the criteria for

classification as held for sale as of September 30, 2026 and December 31, 2025 (in thousands):

For additional information, refer to “Real estate sales” in Note 2 – “Summary of significant accounting policies” to our unaudited

Sales of real estate assets and impairment of real estate

Our completed dispositions of real estate assets during thenine months ended September 30, 2026 and in October 2026

consisted of the following (dollars in thousands):

(1)Represents the aggregate contractual sales price of our dispositions, which differs from the sum of sales proceeds disclosed in our consolidated statement of cash flows

under “Investing activities” (proceeds from sales of real estate), amounts under “Financing activities” (contributions from and sales of noncontrolling interests), and

amounts under “Supplemental disclosure and non-cash investing and financing activities” (non-cash consideration) primarily due to the timing of payment, closing costs,

and other sales adjustments such as prorations of rents and expenses.

(2)Refer to Note 4 – “Consolidated and unconsolidated real estate joint ventures” to our unaudited consolidated financial statements in Item 1 for additional details.

During thenine months ended September 30, 2026, we recognized impairment charges aggre gating$865.9 million, classified

within impairment of real estate in our consolidated statement of operations, primarily related to the following assets:

Greater Boston market

•During the three months ended June 30, 2026, we recognized an additional impairment charge of$24.8 million related toone

vacant office property, aggregating 104,956 RSF, in the Cambridge submarket of our Greater Boston market, to reduce its

carrying amount to its updated estimated fair value less costs to sell of approximately$43.7 million based on recent

negotiations with a potential buyer. This asset was classified as held for sale in December 2025 following our assessment of

the project’s financial outlook, including the significant capital required to redevelop and lease the property. As a result, we

decided to sell this asset and reinvest the sales proceeds in other projects with greater value-creation opportunities, and

recognized an impairment charge of $105.7 million in December 2025. The sale was completed in August 2026, withno gain

or loss recognized.

•Impairment charge of$343.3 million was recognized to reduce the carrying amount ofone development property at 421 Park

Drive in our Fenway submarket, to its estimated fair value less costs to sell of approximately$238.9 million based on recent

negotiations with an institutional user for the sale of 339,668 RSF, representing substantially all of the 392,011 RSF

development project at this location. The asset met the criteria for classification as held for sale as of September 30, 2026,

following our decision to sell and reallocate the substantial near-term capital that the asset would have required to complete

the development toward other projects with greater value-creation opportunities. We expect to complete the sale within the

next 12 months.

San Diego market

•During the three months ended June 30, 2026, an impairment charge of$64.2 million was recognized to reduce the carrying

amount of a land parcel located outside of a Megacampus aggregating 425,000 SF in the Sorrento Mesa submarket of our

San Diego market, to its estimated fair value less costs to sell of approximately$43.3 million. The land parcel met the criteria

for classification as held for sale as of June 30, 2026, following our reevaluation of the capital required to develop the site and

its alignment with our Megacampus strategy, resulting in our decision to monetize the asset and reallocate capital to other

projects with greater value-creation opportunities. The asset is expected to be sold to a residential developer and we expect to

complete the sale within the next 12 months.

•During thethree months ended June 30, 2026, an impairment charge of$28.2 million was recognized to reduce the carrying

amounts offive operating properties, primarily comprising non-laboratory space, aggregating 95,814 RSF and one land parcel

aggregating 144,000 SF in the Sorrento Valley submarket of our San Diego market, to their estimated fair values less costs to

sell of approximately $26.7 million. These assets met the criteria for classification as held for sale as of June 30, 2026,

following our evaluation of the significant capital that would have been required to convert these properties through

redevelopment for laboratory use and their lack of alignment with our Megacampus strategy, resulting in our decision to

monetize these assets and reallocate capital to other projects with greater value-creation opportunities. The sale was

completed in September 2026, withno gain or loss recognized.

•Impairment charge of$9.4 million was recognized during thethree months ended September 30, 2026 to reduce the carrying

amount ofone operating property aggregating 27,689 RSF in the Sorrento Valley submarket of our San Diego market, to its

estimated fair value less costs to sell of approximately$10.9 million. This asset met the criteria for classification as held for

sale as of September 30, 2026, following our evaluation of the asset’s lack of alignment with our Megacampus strategy,

resulting in our decision to sell this asset and reallocate capital to other projects with greater value-creation opportunities. We

expect to complete the sale within the next 12 months.

•During the three months ended September 30, 2026, we recognized an additional impairment charge of$8.5 million related to

four operating properties, aggregating 157,449 RSF in the Sorrento Mesa and Sorrento Valley submarkets of our San Diego

market, to reduce the carrying amounts to their estimated fair values less costs to sell of approximately$54.7 million based on

updated negotiations with prospective buyers. These assets were classified as held for sale as of June 30, 2026, following our

decision to dispose of these properties and reinvest the sales proceeds in other projects with greater value-creation

opportunities, at which time we recognized an impairment charge of$4.2 million. We expect to completethe sales within the

next 12 months.

San Francisco Bay Area market

•During the three months ended June 30, 2026, we recognized an additional impairment charge of$29.3 million related to one

future development project, aggregating 1.1 million SF, in the SoMa submarket of our San Francisco Bay Area market. The

additional impairment charge was recognized to reduce the carrying amount of this asset to its updated estimated fair value

less costs to sell of approximately $41.8 million based on recent negotiations with a potential buyer. The asset was classified

as held for sale in December 2025 following our commitment to dispose of it and reinvest the sales proceeds in other projects

with greater value-creation opportunities, resulting in an impairment charge of$333.4 million recognized in December 2025.

We expect to complete the sale within the next 12 months.

•In June 2026, we entered into a purchase and sale agreement to sell a previously impaired future development project

aggregating 250,000 SF and one operating property aggregating 228,000 RSF in the Palo Alto submarket of our San

Francisco Bay Area market. These assets were classified as held for sale in December 2025, at which time we recognized an

impairment charge of$144.7 million. During the three months ended June 30, 2026, we recognized a$23.3 million partial

reversal of the impairment charge to increase the carrying values of the assets to their aggregate sales price of $163.0 million,

less costs to sell. This adjustment was recorded as a partial offset to impairment of real estate in our consolidated statements

of operations and did not exceed thecumulative impairment previously recognized on these assets. The sale was completed

in July 2026, withno gain or loss recognized.

•Impairment charge of$135.3 million was recognized to reduce the carrying amounts offour vacant office properties,

aggregating 292,746 RSF, located on a non-Megacampus in the Palo Alto submarket of our San Francisco Bay Area market,

to their estimated fair values less costs to sell of approximately$95.3 million. These assets met the criteria for classification as

held for sale as of September 30, 2026. We acquired these office properties in 2022 with the intent to redevelop them into

laboratory space. Following our evaluation of the significant capital that would have been required to convert these properties

and to lease the vacant spaces, we decided to sell these assets and reallocate capital to other projects with greater value-

creation opportunities. We expect to complete the sale within the next 12 months.

•Impairment charge of$79.2 million was recognized to reduce the carrying amounts ofsix non-Megacampus properties

aggregating 103,325 RSF in the San Carlos submarket of our San Francisco Bay Area market, to their estimated fair values

less costs to sell of approximately$39.4 million. These assets met the criteria for classification as held for sale as of

September 30, 2026. We acquired these office-flex assets in 2021 with the intent to redevelop them into laboratory space.

Following our evaluation of the significant capital that would have been required to convert these properties, we decided to sell

the assets and reallocate the proceeds to other projects with greater value-creation opportunities. We expect to complete the

sale within the next 12 months.

•Impairment charge of$41.6 million was recognized to reduce the carrying amount ofone future development project

aggregating 240,000 SF in the Palo Alto submarket of our San Francisco Bay Area market, to its estimated fair value less

costs to sell of approximately$124.2 million. This non-Megacampus asset met the criteria for classification as held for sale as

of September 30, 2026, following our decision to sell the property. Originally acquired in 2018 to support the expansion of our

Megacampus ecosystem, the project was evaluated based on an updated assessment of its financial outlook, including the

capital required to complete the development and lease the property. As a result, we decided to sell the asset and reallocate

the proceeds to other projects with greater value-creation opportunities. We expect to complete the sale within the next 12

months.

Texas market

•Impairment charge of$50.4 million was recognized to reduce the carrying amount of a non-Megacampus land parcel

aggregating 344,000 SF in the Austin submarket of our Texas market, to its estimated fair value less costs to sell of

approximately$11.1 million. The land parcel met the criteria for classification as held for sale as of September 30, 2026,

following our reevaluation of the capital required to develop the site and its alignment with our Megacampus strategy, resulting

in our decision to sell the asset and reallocate capital to other projects with greater value-creation opportunities. We expect to

complete the sale within the next 12 months.

Canada (Non-cluster) market

•During the nine months ended September 30, 2026, we recognized a $55.0 million impairment charge related to a 247,743

RSF non-laboratory property in Canada. The property was classified as held for sale as of June 30, 2026, and written down to

its estimated fair value less costs to sell of approximately$42.5 million. We decided to sell the property rather than make the

significant near-term investment required to redevelop it, and weintend to redeploy the capital to other projects with greater

value-creation opportunities. We expect to complete the sale within the next 12 months.

During the six months ended June 30, 2026, we recognized an additional impairment charge of $27.8 million on our Montreal

portfolio following an amendment to the sales agreement, reducing its carrying amount to its estimated fair value less costs to

sell of approximately $134.5 million. This portfolio had been classified as held for sale since the fourth quarter of 2025, when

we recognized the initial impairment charge of $107.1 million.

During the three months ended September 30, 2026, the sales agreement was terminated and we decided to retain the

portfolio. Accordingly, we reclassified the portfolio from held for sale to held and used and remeasured the assets as required

under GAAP. As a result, we reversed $31.5 million of previously recognized impairment, primarily related to foreign currency

translation losses that were no longer expected to be recognized in earnings. The reversal increased the carrying amount of

the applicable real estate assets and was recorded as a reduction of impairment of real estate in our consolidated statements

of operations.

ARE‑East River Science Park, LLC (“ARE”), a subsidiary of Alexandria Real Estate Equities, Inc., holds an option granted in

2006 to incorporate a land parcel adjacent to and north of the Alexandria Center®for Life Science – New York City campus (the “Option

Parcel”) into the existing ground lease, which would allow for the future development of an additional life science building within the

campus. ARE’s investment in pre‑construction costs related to the Option Parcel aggregated$185.9 million as of September 30, 2026.

On August 6, 2024, ARE filed a lawsuit in the U.S. District Court for the Southern District of New York against New York City

Health + Hospitals Corporation (“H+H”) and the New York City Economic Development Corporation (“EDC”) relating to disputes under

the ground lease and option arrangements governing the Option Parcel. ARE filed an amended complaint on January 24, 2025,

asserting claims for fraudulent inducement, breach of contract, breach of the implied covenant of good faith and fair dealing, and

declaratory relief concerning the continued validity of the option.

On March 27, 2026, the court granted defendants’ partial motion to dismiss the fraud in the inducement and implied covenant

of good faith and fair dealing claims. ARE intends to appeal this order at the appropriate time and to vigorously pursue its claims. The

court did not dismiss ARE’s claim for declaratory relief, which remains pending.

On April 10, 2026, H+H and EDC answered the amended complaint and asserted counterclaims seeking, among other things,

declaratory relief relating to the alleged expiration of the option and entitlement to a$5.0 million security deposit, and damages of at

least$3.8 million. The case remains pending.

As a result of the foregoing matters, the timing of any development of the Option Parcel is currently indeterminate. Excluding

the potential impact of the counterclaims filed by H+H and EDC, this matter exposes us to potential losses ranging from zero to the full

amount of the investment in the project aggregating$185.9 million as of September 30, 2026, depending on the resolution of the

remaining declaratory relief proceedings, the outcome of any appeal, and/or the ability to develop the project. We performed a

probability-weighted recoverability analysis based on initial estimates of various possible outcomes and determined no impairment was

presentas of September 30, 2026.

Separately from, and not as part of, the pending litigation related to the Option Parcel, EDC, on behalf of H+H as the landlord

and itself as lease administrator, delivered on April 20, 2026, a notice alleging that ARE is in default of certain information delivery

obligations under the ground lease relating to the existing operating towers at the Alexandria Center for Life Science – New York City

campus, including sublease, tax, and financial information. The notice asserts that the failure to cure the alleged defaults within the

applicable 30-day cure period would result in daily charges of$1,000 increasing thereafter up to$2,000. ARE disputes the allegations

set forth in the notice of default and intends to vigorously defend against them.

On May 12, 2026, ARE filed a lawsuit in the Commercial Division of the New York State Supreme Court against H+H and EDC,

seeking a Yellowstone injunction, a preliminary injunction, and a temporary restraining order to toll all cure periods under the notice of

default and to enjoin EDC and H+H from issuing a notice of termination (the “NYS Action”). The court denied ARE’s request for a

temporary restraining order on May 13, 2026, and denied ARE’s request for a Yellowstone injunction and a preliminary injunction on

June 15, 2026. On June 17, 2026, ARE filed a notice of appeal from the court’s order, dated June 15, 2026. On July 1, 2026, ARE filed

an application for interim relief pending appeal. Following oral arguments before a single justice, the application was denied without

prejudice to determination by a full panel. On September 10, 2026, the Appellate Division, First Department, denied ARE’s request for

relief pending the determination of its merits appeal. ARE’s merits appeal remains pending.

On July 2, 2026, ARE filed an amended complaint in the NYS Action, adding claims for breach of contract, breach of the

implied covenant of good faith and fair dealing, tortious interference, and unfair competition, and is seeking declaratory and injunctive

relief, based on the defendants’ alleged misuse of ARE’s confidential subtenant information and diversion of an ARE subtenant to a

competing City-sponsored project. On August 6, 2026, EDC and H+H moved to dismiss the amended complaint in its entirety, and the

motion has been fully briefed; oral arguments are scheduled for January 15, 2027. The NYS Action remains pending.

4. CONSOLIDATED AND UNCONSOLIDATED REAL ESTATE JOINT VENTURES

From time to time, we enter into joint venture agreements through which we own a partial interest in real estate entities that

own, develop, and operate real estate properties. As of September 30, 2026, our real estate joint ventures held the following properties:

(1)Refer to the table on the next page that shows the categorization of our real estate joint ventures under the consolidation framework.

(2)Includes 10200, 10290, and 10300 Campus Point Drive and 4135, 4155, 4165, 4224, and 4242 Campus Point Court.

(3)In October 2026, we completed a partial sale of our interest in this joint venture. Refer to “Campus Point by Alexandria Megacampus” within this Note 4 for additional

(4)Includes 9605, 9645, 9675, 9725, 9735, 9805, 9808, 9855, and 9868 Scranton Road and 10055, 10065, and 10075 Barnes Canyon Road.

(5)Includes 9965, 9975, 9985, and 9995 Summers Ridge Road.

(6)Includes 1450, 1500, and 1700 Owens Street, and 455 Mission Bay Boulevard South.

(7)Represents a joint venture with a local real estate operator in which our joint venture partner manages the day-to-day activities that significantly affect the economic

performance of the joint venture.

Our consolidation policy is described under “Consolidation” in Note 2 – “Summary of significant accounting policies” to our

unaudited consolidated financial statements. Consolidation accounting is highly technical, but its framework is primarily based on the

controlling financial interests and benefits of the joint ventures. We generally consolidate a joint venture that is a legal entity we control

(i.e., we have the power to direct the activities of the joint venture that most significantly affect its economic performance) through

contractual rights, regardless of our ownership interest, and where we determine that we have benefits through the allocation of

earnings or losses and fees paid to us that could be significant to the joint venture (the “VIE model”).

We also generally consolidate joint ventures when we have a controlling financial interest through voting rights and where our

voting interest is greater than 50% (the “voting model”). Voting interest differs from ownership interest for some joint ventures. We

account for joint ventures that do not meet the consolidation criteria under the equity method of accounting by recognizing our share of

income and losses.

The table below shows the categorization of our real estate joint ventures under the consolidation framework:

Consolidated real estate joint ventures

Consolidated VIEs’ balance sheet information

We, together with joint venture partners, hold interests in real estate joint ventures that we consolidate in our financial

statements. These existing joint ventures provide significant equity capital to fund a portion of our future construction spending, and our

joint venture partners may also contribute equity into these entities for financing-related activities.

The table below aggregates the balance sheet information of our consolidated VIEs (in thousands):

In determining whether to aggregate the balance sheet information of consolidated VIEs, we considered the similarity of each

VIE, including the primary purpose of these entities to own, manage, operate, and lease real estate properties owned by the VIEs, and

the similar nature of our involvement in each VIE as a managing member. Due to the similarity of the characteristics, we present the

balance sheet information of these entities on an aggregated basis. As of September 30, 2026, none of our consolidated VIEs’ assets

were subject to restrictions that limit their use to settle specific obligations of the VIEs, no creditors or other partners of our consolidated

VIEs had recourse to our general credit, and our maximum exposure to our consolidated VIEs was limited to our variable interests in

each VIE.

99 Coolidge Avenue

In July 2025, we amended the agreement for our consolidated real estate joint venture at 99 Coolidge Avenue in our

Cambridge/Inner Suburbs submarket. Pursuant to the amendment, the carrying amount of our partner’s noncontrolling interest was

adjusted from$42.0 million to$48.7 million, and the interest was converted into a redeemable noncontrolling interest that accrued a

fixed 4.05% annual preferred return (“distributions”). In January 2026, our partner exercised its option to require us to purchase its

entire preferred interest, and the redemption was completed in January 2026 for$49.7 million, inclusive of unpaid distributions.

Campus Point by Alexandria Megacampus

As of September 30, 2026, we held a 59.3% ownership interest in a consolidated joint venture that owns substantially all of the

Campus Point by Alexandria Megacampus, comprising seven operating properties aggregating 1.6 million RSF, located in our

University Town Center submarket of our San Diego market.

In October 2026, we completed the sale of an approximately 29% noncontrolling interest in the consolidated real estate joint

venture that owns substantially all of the Campus Point by Alexandria Megacampus for$475.0 million. We expect our new partner’s

initial share of the annual distributions to approximate 5.5% of the $475.0 million contributed capital. Upon completion of the sale, our

ownership interest in the real estate joint venture decreased to approximately 30%. We expect to fund themajority of future construction

costs at the Megacampus, which is expected to increase our ownership interest in the campus over time to over 50%, with the

ownership interests of our new joint venture partner and existing joint venture partner decreasing to below 20% and 30%, respectively.

Our new joint venture partner has the right to require us to purchase its interest after the seventh anniversary of the transaction

in exchange for shares of our common stock, subject to a contractual share issuance limit, or, at our election, in cash or a combination

of cash and shares.

We retained control and therefore continue to consolidate the properties held by the real estate joint venture. Accordingly, we

accounted for the$44.2 million difference between the consideration received and the book value of our interest sold as an increase to

additional paid-in capital, with no gain recognized in earnings.

Noncontrolling interests in consolidated real estate joint ventures

Noncontrolling interests represent the third-party interests in consolidated real estate joint ventures in which we have a

controlling interest. Noncontrolling interests are adjusted for additional contributions and distributions, the proportionate share of the net

earnings or losses, and other comprehensive income or loss. Distributions, profits, and losses related to these entities are allocated in

accordance with the respective operating agreements. During thenine months ended September 30, 2026 and 2025, we distributed

$171.2 million and $186.8 million, respectively, to our consolidated real estate joint venture partners.

Unconsolidated real estate joint ventures

Our investments in unconsolidated real estate joint ventures, accounted for under the equity method and classified in

investments in unconsolidated real estate joint ventures in our consolidated balance sheets, consisted of the following as of

September 30, 2026 and December 31, 2025 (in thousands):

As of September 30, 2026, our maximum exposure related to our only unconsolidated VIE, 101 West Dickman Street, is

limited to our investment in this joint venture and a guarantee of up to$5.4 million of the outstanding balance related to the VIE’s

secured construction loan.

Below are key terms of unconsolidated real estate joint ventures’ secured loans as of September 30, 2026 (dollars in

(1)Includes interest expense and amortization of loan fees.

(2)Represents outstanding principal, net of unamortized deferred financing costs, as of September 30, 2026.

(3)In October 2026, the unconsolidated real estate joint venture refinanced this debt with a new $22.5 million secured note payable bearing interest at SOFR+1.85% and

maturing in October 2030. As of September 30, 2026, our investment in this unconsolidated real estate joint venture was$9.9 million.

(4)This loan is subject to a SOFR floor of 0.75%.

5. LEASES

Refer to “Lease accounting” in Note 2 – “Summary of significant accounting policies” to our unaudited consolidated financial

statements for information about lease accounting standards that set principles for the recognition, measurement, presentation, and

disclosure of leases for both parties to a lease agreement (i.e., lessees and lessors).

Leases in which we are the lessor

As of September 30, 2026, we had 328 properties aggregating 36.5 million operating RSF in key cluster locations, including

Greater Boston, San Diego, the San Francisco Bay Area, Seattle, Maryland, Research Triangle, and New York City. We primarily focus

on developing Class A/A+ properties in AAA life science and advanced technology innovation clusters that offer the scale and strategic

design integral to our Megacampus strategy. Strategically located near top academic and medical research institutions, our

Megacampus ecosystems feature curated amenities and services and convenient access to transit, creating environments that help our

tenants attract and retain top talent.

As of September 30, 2026, all leases in which we are the lessor were classified as operating leases, with the exception ofone

direct financing andone sales-type lease. Our leases are described below.

Operating leases

As of September 30, 2026, our 328 properties were subject to operating lease agreements. Five of these properties are

subject to operating lease agreements that each contain a purchase option as described below:

(i)Two of these properties, representingtwo land parcels in the San Francisco Bay Area market, are subject to lease

agreements that each contain an option for the lessee to purchase the underlying asset from us at fair market value during

each of the 30-day periods commencing on the dates that are 15 years,30 years, and 74.5 years after the rent

commencement date of October 1, 2017. The remaining lease term related to each of thetwo land parcels is 66.2 years.

(ii)Two operating properties in the Seattle market, held by a consolidated real estate joint venture, are subject to purchase

options held by our partner in this joint venture, which is also a tenant at these properties. One purchase option allows our

partner to purchase our 30% interest in one property for$40.0 million in 2031. Contingent upon the exercise of this option,

the second purchase option allows our partner to purchase our 30% interest in one property for$69.1 million in 2034. Our

partner’s remaining lease terms for these operating leases are 6.4 years and 18.0 years, respectively.

(iii)One property subject to an operating lease agreement contains a purchase option exercisable at fair market value in

March 2034.

Certain operating leases contain options for tenants to extend their leases at prevailing market rates at the time of expiration.

In addition, certain operating leases contain an early termination option that requires advance notification and payment of an early

termination fee by the tenant.

At the commencement of each lease, we establish the lease term comprising the noncancelable period for each lease together

with periods covered by options to extend or terminate the lease that we determine the lessee is reasonably certain to exercise. Our

assessment of whether a lessee is reasonably certain to exercise or not exercise an option considers all economic factors relevant to

the assessment, including property-based, market-based, and tenant-based factors. We do not reassess the lease term or a lessee

option to purchase the underlying asset unless there is a lease modification that is not accounted for as a separate contract.

Future lease payments to be received under the terms of our operating lease agreements, excluding expense

reimbursements, in effect as of September 30, 2026 are outlined in the table below (in thousands):

Refer to Note 3 – “Investments in real estate” to our unaudited consolidated financial statements for additional information

about our owned real estate assets, which are the underlying assets under our operating leases.

Direct financing and sales-type leases

As of September 30, 2026, we haveone direct financing lease agreement, with a net investment balance of $43.2 million, for a

parking structure with a remaining lease termof 66.2 years. The lessee has an option to purchase the underlying asset at fair market

value during each of the 30-day periods commencing on the dates that are 15 years,30 years, and 74.5 years after the rent

commencement date of October 1, 2017.

As of September 30, 2026, we also have one sales-type leasefor a property in the Seattle market. As of September 30, 2026,

the net investment in this lease is$16.9 million. At the end of the lease term in 2026, title to the property under this lease will transfer to

the tenant for a sales price of approximately$18.5 million.

As of September 30, 2026, our estimated provision for expected credit losses related to our direct financing and sales-type

leases aggregated$1.8 million, which was predominantly related to our direct financing lease. We estimate the provision for expected

credit losses related to our direct financing lease using a probability of default methodology, which incorporates the borrower’s

investment-grade credit rating from S&P Global Ratings, to evaluate the probability of default. Additionally, we incorporate the projected

value of the real estate securing the investments to estimate potential recoveries in the event of default, among other inputs. The

estimate of the expected credit loss related to our sales-type lease was determined using historical industry losses and transaction-

specific information, including the estimated fair value of the underlying real estate asset securing this transaction, the short-term nature

of this lease, and other available information. For further details, refer to “Provision for expected credit losses” in Note 2 – “Summary of

The components of our aggregate net investment in our direct financing and sales-type leases as of September 30, 2026 and

December 31, 2025 are summarized in the table below (in thousands):

Future lease payments to be received under the terms of our direct financing and sales-type leases as of September 30, 2026

are outlined in the table below (in thousands):

Our income from rentals includes revenue related to agreements for the rental of our real estate, which primarily includes

revenues subject to the lease accounting standard and the revenue recognition accounting standard as shown below (in thousands):

Revenues subject to the revenue recognition accounting standard and classified in income from rentals consist primarily of

short-term parking revenues that are not considered lease revenues under the lease accounting standard. Refer to “Revenues” and

“Recognition of revenue arising from contracts with customers” in Note 2 – “Summary of significant accounting policies” to our

unaudited consolidated financial statements for additional information.

Residual value risk management strategy

Our leases do not have guarantees of residual value on the underlying assets. We manage risk associated with the residual

value of our leased assets by (i) evaluating each potential acquisition of real estate to determine whether it meets our business

objective to invest primarily in high-demand markets, (ii) directly managing our leased properties, conducting frequent property

inspections, proactively addressing potential maintenance issues, and/or timely resolving any occurring issues, and (iii) carefully

selecting our tenants and monitoring their credit quality throughout their respective lease terms.

Leases in which we are the lessee

Operating lease agreements

We have ground and office operating lease agreements in which we are the lessee. Certain of these leases have options to

extend or terminate the contract terms upon meeting certain criteria. There are no notable restrictions or covenants imposed by the

leases, nor guarantees of residual value.

We recognize a right-of-use asset, which is classified within other assets in our consolidated balance sheets, and a related

liability, which is classified within accounts payable, accrued expenses, and other liabilities in our consolidated balance sheets, to

account for our future obligations under ground and office lease arrangements in which we are the lessee. Refer to “Lessee accounting”

in Note 2 – “Summary of significant accounting policies” to our unaudited consolidated financial statements.

As of September 30, 2026, the present value of the remaining contractual payments aggregating$754.4 million under our

operating lease agreements, including our extension options that we are reasonably certain to exercise, was$354.0 million. Our

corresponding operating lease right-of-use assets, adjusted for initial direct leasing costs and other consideration exchanged with the

landlord prior to the commencement of the lease, aggregated $686.2 million. As of September 30, 2026, the weighted-average

remaining lease term of operating leases in which we are the lessee was approximately 60 years, including extension options that we

are reasonably certain to exercise, and the weighted-average discount rate was 4.7%. The weighted-average discount rate is based on

the incremental borrowing rate estimated for each lease, which is the interest rate that we estimate we would have to pay to borrow on

a collateralized basis over a similar term for an amount equal to the lease payments.

Ground lease obligations as of September 30, 2026 included leases for 31 of our properties, which accounted for

approximately 9% of our total number of properties. Our ground lease obligations have remaining lease terms ranging from

approximately 28 to 97 years, including extension options that we are reasonably certain to exercise.

The reconciliation of future lease payments under noncancelable operating leases in which we are the lessee to the operating

lease liability reflected in our unaudited consolidated balance sheet as of September 30, 2026 is in the table below (in thousands):

Lessee operating costs

Operating lease costs relate to our ground and office leases in which we are the lessee. Ground leases generally require fixed

annual rent payments and may also include escalation clauses and renewal options. For thenine months ended September 30, 2026

and 2025, amounts paid and classified as operating activities in our unaudited consolidated statements of cash flows for leases in which

we are the lessee aggregated $18.0 million and$165.2 million, respectively. The decrease is primarily due to the ground lease

prepayment of$135.0 million made in January 2025 for a 24-year lease term extensionto our existing ground lease agreement at the

Alexandria Technology Square® Megacampus in our Cambridge submarket.

Our operating lease obligations related to our office leases have remaining terms of up to 10 years, exclusive of extension

options. For thethree and nine months ended September 30, 2026 and 2025, our costs for operating leases in which we are the lessee

were as follows (in thousands):

6. CASH, CASH EQUIVALENTS, AND RESTRICTED CASH

Cash, cash equivalents, and restricted cash consisted of the following as of September 30, 2026 and December 31, 2025 (in

7. INVESTMENTS

We hold investments in publicly traded companies and privately held entities primarily involved in the life science industry. As a

REIT, we generally limit our ownership of each individual entity’s voting stock to less than 10%. Weevaluate each investment to

determine whether we have the ability to exercise significant influence, but not control, over an investee. We evaluate investments in

which our ownership is equal to or greater than 20%, but less than or equal to 50%, of an investee’s voting stock with a presumption

that we have this ability. For our investments in limited partnerships that maintain specific ownership accounts, we presume that such

ability exists when our ownership interest exceeds 3% to 5%. In addition to our ownership interest, we consider whether we have a

board seat or whether we participate in the investee’s policy-making process, among other criteria, to determine if we have the ability to

exert significant influence, but not control, over an investee. If we determine that we have such ability, we account for the investment

under the equity method, as described below.

From time to time, we may hold equity investments in publicly traded companies that are subject totemporary contractual sale

restrictions. We do not recognize a discount related to such contractual sale restrictions.

Investments accounted for under the equity method

Under the equity method of accounting, we initially recognize our investment at cost and subsequently adjust the carrying

amount of the investment for our share of earnings or losses reported by the investee, distributions received, and other-than-temporary

impairments.

As of September 30, 2026, we hadnine investments in limited partnerships maintaining specific ownership accounts for each

investor, which were accounted for under the equity method. These investments aggregated$394.4 million. Our ownership interest in

each of these nine investments was greater than 5%.

Investments that do not qualify for the equity method of accounting

For investees over which we determine that we do not have the ability to exercise significant influence or control, we account

for each investment depending on whether it is an investment in a (i) publicly traded company, (ii) privately held entity that reports NAV

per share, or (iii) privately held entity that does not report NAV per share, as described below.

Investments in publicly traded companies

Our investments in publicly traded companies are classified as investments with readily determinable fair values and are

presented at fair value in our consolidated balance sheets, with changes in fair value classified in investment income (losses) in our

consolidated statements of operations. The fair values for our investments in publicly traded companies are determined based on sales

prices or quotes available on securities exchanges.

Investments in privately held companies

Our investments in privately held entities without readily determinable fair values consist of (i) investments in privately held

entities that report NAV per share and (ii) investments in privately held entities that do not report NAV per share. These investments are

accounted for as follows:

Investments in privately held entities that report NAV per share

Investments in privately held entities that report NAV per share, such as our privately held investments in limited partnerships,

are presented at fair value using NAV as a practical expedient, with changes in fair value classified in investment income (losses) in our

consolidated statements of operations. We use NAV per share reported by limited partnerships generally without adjustment, unless we

are aware of information indicating that the NAV reported by a limited partnership does not accurately reflect the fair value of the

investment at our reporting date.

Investments in privately held entities that do not report NAV per share

Investments in privately held entities that do not report NAV per share are accounted for using a measurement alternative

under which these investments are measured at cost, adjusted for observable price changes and impairments, with changes classified

in investment income (losses) in our consolidated statements of operations.

An observable price arises from an orderly transaction for an identical or similar investment of the same issuer, which is

observed by an investor without expending undue cost and effort. Observable price changes result from, among other things, equity

transactions of the same issuer executed during the reporting period, including subsequent equity offerings or other reported equity

transactions related to the same issuer. To determine whether these transactions are indicative of an observable price change, we

evaluate, among other factors, whether these transactions have similar rights and obligations, including voting rights, distribution

preferences, and conversion rights to the investments we hold.

7. INVESTMENTS (continued)

Impairment evaluation of equity method investments and investments in privately held entities that do not report NAV per share

We monitor equity method investments and investments in privately held entities that do not report NAV per share for new

developments, including operating results, prospects and results of clinical trials, new product initiatives, new collaborative agreements,

capital-raising events, and merger and acquisition activities. These investments are evaluated on the basis of a qualitative assessment

for indicators of impairment by monitoring the presence of the following triggering events or impairment indicators:

(i)a significant deterioration in the earnings performance, credit rating, asset quality, or business prospects of the investee;

(ii)a significant adverse change in the regulatory, economic, or technological environment of the investee;

(iii)a significant adverse change in the general market condition, including the research and development of technology and

products that the investee is bringing or attempting to bring to the market;

(iv)significant concerns about the investee’s ability to continue as a going concern; and/or

(v)a decision by investors to cease providing support or reduce their financial commitment to the investee.

If such indicators are present, we are required to estimate the investment’s fair value and immediately recognize an

impairment charge in an amount equal to the investment’s carrying value in excess of its estimated fair value.

Investment income/loss recognition and classification

We recognize both realized and unrealized gains and losses in our consolidated statements of operations, classified in

investment income (losses) in our consolidated statements of operations. Unrealized gains and losses represent:

(i)changes in fair value for investments in publicly traded companies;

(ii)changes in NAV for investments in privately held entities that report NAV per share;

(iii)observable price changes for investments in privately held entities that do not report NAV per share; and

(iv)our share of unrealized gains or losses reported by our equity method investees.

Realized gains and losses on our investments represent the difference between proceeds received upon disposition of

investments and their historical or adjusted cost basis. For our equity method investments, realized gains and losses represent our

share of realized gains or losses reported by the investee. Impairments are realized losses, which result in an adjusted cost basis, and

represent charges to reduce the carrying values of investments in privately held entities that do not report NAV per share and equity

method investments, if impairments are deemed other than temporary, to their estimated fair value.

Funding commitments to investments in privately held entities that report NAV

We are committed to funding approximately$317.5 million for our investments in privately held entities that report NAV. Our

funding commitments expire at various dates over the next 11 years, with a weighted-average expiration of 7.8 years as of September

30, 2026. These investments are not redeemable by us, but we may receive distributions from these investments throughout their

terms. Our investments in privately held entities that report NAV generally have expected initial termsin excess of 10 years. The

weighted-average remaining term during which these investments areexpected to be liquidated was 5.4 years as of September 30,

The following tables summarize our investments as of September 30, 2026 and December 31, 2025 (in thousands):

7. INVESTMENTS (continued)

Cumulative gains and losses (realized and unrealized) on investments in privately held entities that do not report NAV still held

as of September 30, 2026 aggregated to aloss of$137.8 million, which consisted ofupward adjustments aggregating$50.6 million,

downward adjustments aggregating$10.8 million, and impairments aggreg ating$177.6 million.

Our investment income (losses) for thethree and nine months ended September 30, 2026 and 2025 consisted of the following

(1)Consists of realized gains of$16.0 million and$44.5 million, partially offset by impairment charges of$13.6 million and $35.0 million during thethree and nine months

ended September 30, 2026, respectively.

(2)Investment income of$24.0 million and$152.6 million included $340 thousand of equity inlosses and$28.2 million of equity inearnings of our equity method

investments during thethree and nine months ended September 30, 2026, respectively.

Additional details on our non-real estate investments still held as of the end of each period are presented below (in thousands):

Refer to “Investments” in Note 2 – “Summary of significant accounting policies” to our unaudited consolidated financial

statements for additional information.

8. OTHER ASSETS

The following table summarizes the components of other assets as of September 30, 2026 and December 31, 2025 (in

Notes receivable

Our notes receivable as of September 30, 2026 and December 31, 2025 consisted of the following (dollars in thousands):

Our notes receivable represent held-to-maturity debt securities carried at amortized cost and are generally secured by real

estate. Under the current expected credit losses accounting standard, we are required to estimate and, if necessary, recognize a

provision for expected credit losses related to these notes. We do not have a history of losses on such securities; therefore, we utilize

available information on historical losses for the commercial real estate industry. We determine expected credit losses for our notes

receivable using historical industry losses and considering loan-specific information, including credit ratings of the borrowers, estimated

fair values of underlying real estate assets, loan-to-value ratios, the presence of guarantors, and/or other available information. During

thethree and nine months ended September 30, 2026, no adjustment to theprovision for expected credit losses related to our notes

receivable was required. The provision is evaluated on an ongoing basis, with any necessary adjustments recognized in the

corresponding period.

9. FAIR VALUE MEASUREMENTS

We provide fair value information about all financial instruments for which it is practicable to estimate fair value. We measure

and disclose the estimated fair value of financial assets and liabilities by utilizing a fair value hierarchy that distinguishes between data

obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant

assumptions. This hierarchy consists of three broad levels, as follows: (i) quoted prices in active markets for identical assets or liabilities

(Level 1), (ii) significant other observable inputs (Level 2), and (iii) significant unobservable inputs (Level 3). Significant other observable

inputs can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or

liability, such as interest rates, foreign exchange rates, and yield curves. Significant unobservable inputs are typically based on an

entity’s own assumptions, since there is little, if any, related market activity. In instances in which the determination of the fair value

measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the

entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety.

Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers

factors specific to the asset or liability.

Assets and liabilities measured at fair value on a recurring basis

The following table sets forth the assets and liabilities that we measure at fair value on a recurring basis by level in the fair

value hierarchy as of September 30, 2026 and December 31, 2025 (in thousands). There wereno transfers of assets measured at fair

value on a recurring basis to or from Level 3 in the fair value hierarchy during thenine months ended September 30, 2026.

Our investments in publicly traded companies represent investments with readily determinable fair values, and are carried at

fair value, with changes in fair value classified in investment income (losses) in our consolidated financial statements. We also hold

investments in privately held entities, which consist of (i) investments that report NAV and (ii) investments that do not report NAV, as

further described below.

Our investments in privately held entities that report NAV, such as our privately held investments in limited partnerships, are

carried at fair value using NAV as a practical expedient, with changes in fair value classified innet income. As of September 30, 2026

and December 31, 2025, the carrying values of investments in privately held entities that report NAV aggregated$680.4 million and

$512.4 million, respectively. These investments are excluded from the fair value hierarchy above as required by the fair value

accounting standard. We estimate the fair value of each of our investments in limited partnerships based on the most recent NAV

prepared by the general partner and reported by each limited partnership. As a result, the determination of fair values of our

investments in privately held entities that report NAV generally does not involve significant estimates, assumptions, or judgments on our

part.

Our cross-currency swap agreements are recognized at fair value. Refer to Note 2 – “Summary of significant accounting

policies” and Note 11 – “Hedge agreements” to our unaudited consolidated financial statements for additional information.

9. FAIR VALUE MEASUREMENTS (continued)

Assets and liabilities measured at fair value on a nonrecurring basis

The following table sets forth our assets measured at fair value on a nonrecurring basis, categorized by level within the fair

value hierarchy, as of September 30, 2026 and December 31, 2025 (in thousands).

(1)These amounts represent the aggregate carrying amounts of real estate assets for which adjustments based on nonrecurring fair value measurements were recognized

during the respective periods, including assets for which impairment losses or reversals of previously recognized impairment losses were recorded. These assets

primarily include a subset of our total real estate assets classified as held for sale as of September 30, 2026 and December 31, 2025. The fair values for these real

estate assets were estimated based on executed purchase and sale agreements, letters of intent, valuations provided by third-party real estate brokers, or market

comparables from recent transactions. Refer to “Investments in real estate” in Note 2 – “Summary of significant accounting policies” and “Assets held for sale” in Note 3

– “Investments in real estate” to our unaudited consolidated financial statements for additional information.

(2)These amounts represent the carrying amounts of our equity investments in privately held entities with observable price changes for which adjustments based on

nonrecurring fair value measurements were recognized during the respective periods. These amounts are included in the investment balances of $1.74 billion and $1.50

billion in our unaudited consolidated balance sheets as of September 30, 2026 and December 31, 2025, respectively, disclosed in Note 7 – “Investments” to our

unaudited consolidated financial statements.

(3)These amounts are included in the investments in privately held entities without observable price changes balances aggregating $406.4 million and$413.3 million as of

September 30, 2026 and December 31, 2025, respectively, disclosed in Note 7 – “Investments” to our unaudited consolidated financial statements, and represent the

carrying amounts of investments in privately held entities that do not report NAV for which impairments have been recognized during the respective periods in

accordance with the measurement alternative guidance described in “Investments” in Note 2 – “Summary of significant accounting policies” to our unaudited

Investments in privately held entities that do not report NAV

Our investments in privately held entities that do not report NAV are measured at cost, adjusted for observable price changes

and impairments, with changes recognized in net income (loss). These investments are adjusted based on the observable price

changes in orderly transactions for the identical or similar investment of the same issuer. Further adjustments are not made until

another observable transaction occurs. Therefore, the determination of fair values of our investments in privately held entities that do

not report NAV does not involve significant estimates and assumptions or subjective and complex judgments.

We also subject our investments in privately held entities that do not report NAV to a qualitative assessment for indicators of

impairment. If indicators of impairment are present, we are required to estimate the investment’s fair value and immediately recognize

an impairment charge in an amount equal to the investment’s carrying value in excess of its estimated fair value.

The estimates of fair value typically incorporate valuation techniques that include an income approach reflecting a discounted

cash flow analysis, and a market approach that includes a comparative analysis of acquisition multiples and pricing multiples generated

by market participants. In certain instances, we may use multiple valuation techniques for a particular investment and estimate its fair

value based on an average of multiple valuation results.

Refer to Note 7 – “Investments” to our unaudited consolidated financial statements for additional information.

Assets and liabilities not measured at fair value in the statement of financial position but for which the fair value is disclosed

The fair values of our unsecured senior notes payable, junior subordinated notes payable, and the amounts outstanding on our

unsecured senior line of credit and commercial paper program were estimated using widely accepted valuation techniques, including

discounted cash flow analyses using significant other observable inputs such as available market information on discount and

borrowing rates with similar terms, maturities, and credit ratings. Because the valuations of our financial instruments are based on these

types of estimates, the actual fair value of our financial instruments may differ materially if our estimates do not prove to be accurate.

Additionally, the use of different market assumptions or estimation methods may have a material effect on the estimated fair value

amounts.

9. FAIR VALUE MEASUREMENTS (continued)

As of September 30, 2026 and December 31, 2025, the book and estimated fair values of our unsecured senior notes payable,

junior subordinated notes payable, and the amounts outstanding under our unsecured senior line of credit and commercial paper

program, including the level within the fair value hierarchy for which the estimates were derived, were as follows (in thousands):

The carrying values of cash and cash equivalents, restricted cash, tenant receivables, deposits, notes receivable, accounts

payable, accrued expenses, and other short-term liabilities approximate their fair value.

10. SECURED AND UNSECURED SENIOR DEBT

The following table summarizes our outstanding indebtedness and respective principal payments remaining as of September 30, 2026 (dollars in thousands):

(1)Represents the weighted-average interest rate as of the end of the applicable period, including amortization of loan fees, amortization of debt premiums (discounts), and other bank fees.

(2)Reflects any extension options that we control.

(3)Refer to footnote 3 on the following page.

(4)Refer to footnote 4 on the following page. In September 2026, we amended and restated our$5.0 billion unsecured senior line of credit, which, among other changes, extended the maturity date from January 22, 2030 to January 22, 2032,

including extension options that we control. In addition, the amendment reduces the applicable borrowing rate to SOFR plus 0.725% from SOFR plus 0.835%.

10. SECURED AND UNSECURED SENIOR DEBT (continued)

The following table summarizes our debt outstanding as of September 30, 2026 (dollars in thousands):

(1)Represents the weighted-average interest rate as of the end of the applicable period, including expense/income related to the amortization of loan fees, amortization of

debt premiums (discounts), and other bank fees.

(2)As of September 30, 2026, we hadno outstanding balance on our unsecured senior line of credit.

(3)Our junior subordinated notes will initially bear interest at 7.250% per year through, but excluding, February 15, 2032. Thereafter, the interest rate will reset every five

years to the five-year U.S. Treasury rate plus 2.889%, subject to a minimum interest rate of 7.250%. In addition, we may redeem the notes at 100% of principal plus

accrued and unpaid interest during the period beginning November 17, 2031 and ending on February 15, 2032, and thereafter on any interest payment date.

(4)We calculate the weighted-average remaining term of our commercial paper notes by using the maturity date of our unsecured senior line of credit. Using the maturity

date of our outstanding commercial paper notes, the consolidated weighted-average maturity of our debt is 11.2 years. The commercial paper notes sold during thenine

months ended September 30, 2026 were issued at aweighted-average yield to maturity of 4.19% and had a weighted-average maturity term of 14 days. Our total

weighted-average remaining term also assumes the full maturity of our junior subordinated notes payabledue in 2057.

Issuance and repayments of unsecured senior notes payable

In February 2026, we completed tender offers to repurchase an aggregate debt principal amount of approximately$1.33 billion

of a portion of our outstanding 4.00% Senior Notes due 2050,3.00% Senior Notes due 2051, and 3.55% Senior Notes due 2052. Cash

consideration paid was$952.2 million. The repurchase was primarily funded through the issuance of$750.0 million of 5.25% unsecured

senior notes due 2036, and approximately$200 million of short-term borrowings under our commercial paper program. In connection

with the debt repurchase, we recognized a gain on early extinguishment of debt aggregating$366.4 million, including the write-off of

unamortized debt issuance costs and other transaction-related costs.

In January 2026, we repaid$300.0 million of 4.30% unsecured senior notes payable upon maturity. No gain or loss was

incurred in connection with this repayment.

In April 2026, we repaid$350.0 million of 3.80% unsecured senior notes payable upon maturity. No gain or loss was incurred

in connection with this repayment.

Issuance of junior subordinated notes payable

In August 2026, we completed a public offering of$1.00 billion aggregate principal amount of 7.250% Series A fixed-to-fixed

February 15, 2032. Thereafter, the interest rate will reset every five years to the five-year U.S. Treasury rate plus 2.889%, subject to a

minimum interest rate of 7.250%. We may elect to defer interest payments for up to five consecutive years, subject to the terms of the

notes, including certain restrictions on paying dividends and repurchasing equity. The notes may be redeemed at our option in whole or

in part at 100% of principal plus accrued and unpaid interest during the period beginning November 17, 2031 and ending on

February 15, 2032, and thereafter on any interest payment date. The notes may also be redeemed in whole, but not in part, at 100% of

principal plus accrued and unpaid interest upon certain tax events and at 102% of principal plus accrued and unpaid interest upon

certain rating agency events.

$5.0 billion unsecured senior line of credit

In September 2026, we amended and restated our$5.0 billion unsecured senior line of credit which, among other changes,

extended the maturity date from January 22, 2030 to January 22, 2032, including extension options that we control. The amendment

also reduced the applicable borrowing rate to SOFR plus 0.725% from SOFR plus 0.835% and eliminated the existing sustainability-

linked pricing adjustments. The facility fee was revised to 0.15% from 0.14%. In connection with the amendment, we recognized a loss

on early extinguishment of debt of approximately$3.3 million for the partial write-off of unamortized loan fees.

As of September 30, 2026, our unsecured senior line of credit, which matures in 2032, including extension options under our

control, had aggregate commitments of$5.0 billion, and bore an interest rate of SOFR plus 0.725%. In addition to the cost of borrowing,

the unsecured senior line of credit is subject to an annual facility fee of 0.15% based on the aggregate commitments outstanding. As of

September 30, 2026, we hadno outstanding balance on our unsecured senior line of credit.

10. SECURED AND UNSECURED SENIOR DEBT (continued)

$2.50 billion commercial paper program

Our commercial paper program allows us to issue up to $2.50 billion of commercial paper notes that bear interest at short-term

fixed rates with a maturity of generally 30 days or less and a maximum maturity of 397 days from the date of issuance. This program is

back-stopped by our unsecured senior line of credit, and at all times we expect to retain a minimum undrawn amount of borrowing

capacity under our unsecured senior line of credit equal to the amount of commercial paper notes outstanding. We use the net

proceeds from the issuances of the notes for general working capital and other general corporate purposes, which may include, but are

not limited to, the repayment of other debt and selective development, redevelopment, or acquisition of properties. During thenine

months ended September 30, 2026, the notes were issued at aweighted-average yield to maturity of 4.19% and had a weighted-

average maturity term of 14 days. As of September 30, 2026, we had $1.09 billion outstanding under our commercial paper program.

The following table summarizes interest expense for thethree and nine months ended September 30, 2026 and 2025 (in

11. HEDGE AGREEMENTS

We have fixed-to-fixed cross-currency swap agreements designated as net investment hedges to mitigate the impact of

fluctuations in the USD–CAD exchange rate on our real estate investments in Canada. Under the terms of these agreements, USD

fixed interest amounts are payable to us and CAD fixed interest amounts are payable to the counterparty.

On April 30, 2026, our cross-currency swap agreements with an aggregate notional amount of CAD$340.0 million matured.

No amounts were reclassified from accumulated other comprehensive income to earnings because the related net investment had not

been sold or substantially liquidated.

During the three months ended June 30, 2026, we entered into new fixed-to-fixed cross-currency swap agreements

designated as net investment hedges with an aggregate notional amount of CAD$270.0 million. During the three months ended

September 30, 2026, we terminated these agreements and entered into new fixed-to-fixed cross-currency swap agreements with the

same aggregate CAD notional amount, designated as net investment hedges, which were deemed effective on the commencement

date. These agreements mature on January 31, 2028.

As of September 30, 2026, our outstanding cross-currency swap agreements had an aggregate notional amount of CAD

$270.0 million, or approximately USD$194.1 million, and were highly effective.

Unrealized gains or losses on these agreements are recognized in accumulated other comprehensive income and will be

reclassified into net income upon complete or substantially complete liquidation of our investment in Canada. Refer to “Hedge

accounting” in Note 2 – “Summary of significant accounting policies” to our unaudited consolidated financial statements for additional

The tables below summarize the fair value of our cross-currency swap agreements designated as net investment hedges and

12. ACCOUNTS PAYABLE, ACCRUED EXPENSES, AND OTHER LIABILITIES

The following table summarizes the components of accounts payable, accrued expenses, and other liabilities as of

September 30, 2026 and December 31, 2025 (in thousands):

As of September 30, 2026 and December 31, 2025, our conditional asset retirement obligations primarily consisted of the soil

and groundwater remediation liabilities associated with certain properties. Some of our properties may contain asbestos or may be

subjected to other hazardous or toxic substances, which, under certain conditions, require remediation. We engage independent

environmental consultants to conduct Phase I or similar environmental assessments at our properties. This type of assessment

generally includes a site inspection, interviews, and a public records review; asbestos, lead-based paint, and mold surveys; subsurface

sampling; and other testing. We recognize a liability for the fair value of a conditional asset retirement obligation when the fair value of

the liability can be reasonably estimated. In addition, environmental laws and regulations subject our tenants, and potentially us, to

liability that may result from our tenants’ routine handling of hazardous substances and wastes as part of their operations at our

properties. As of September 30, 2026, we are not aware of any additional environmental liability that we believe would require additional

disclosures or recognition in our consolidated financial statements.

13. EARNINGS PER SHARE

We grant two types of restricted stock awards: (i) restricted stock awards with nonforfeitable dividends and (ii) restricted stock

awards with forfeitable dividends.

Unvested restricted stock awards (“RSAs”) with nonforfeitable dividends are considered participating securities and included in

the computation of EPS using the two-class method. Under this method, we allocate net income (after amounts attributable to

noncontrolling interests) to common stockholders and these RSAs by using the weighted-average shares of each class outstanding for

quarter-to-date and year-to-date periods independently, based on their respective participation rights to dividends declared (or

accumulated) and undistributed earnings.

Unvested RSAs with forfeitable dividends do not qualify as participating securities under the two-class method because the

dividends are forfeited if the awards do not vest. As a result, undistributed earnings are not allocated to these awards prior to vesting,

and these awards have no effect on the computation of basic EPS while unvested. Once these awards vest, they are included in the

denominator of basic EPS, weighted for the portion of the reporting period they were vested. Prior to vesting, these awards are included

in the denominator of diluted EPS if they are dilutive, which is determined using the treasury stock method. Under this method,

incremental shares are calculated as the difference between the total unvested shares and the number of shares that could

hypothetically be repurchased using the assumed proceeds (including unrecognized compensation cost related to these awards).

These incremental shares are weighted for the portion of the reporting period they were unvested and are included in the diluted EPS

denominator only if their inclusion reduces EPS (i.e., if they are not antidilutive).

In addition, from time to time, we enter into forward equity sales agreements. We consider the potential dilution resulting from

the forward equity sales agreements on the EPS calculations. At inception, the agreements do not have an effect on the computation of

basic EPS as no shares are delivered until settlement. The common shares issued upon the settlement of the forward equity sales

agreements, weighted for the period these common shares were outstanding, are included in the denominator of basic EPS. To

determine the dilution resulting from the forward equity sales agreements during the period of time prior to settlement, we calculate the

number of weighted-average shares outstanding – diluted using the treasury stock method. As of September 30, 2026, no forward

equity sales agreements were outstanding.

The table below reconciles the numerators and denominators of the basic and diluted EPS computations for thethree and nine

months ended September 30, 2026 and 2025 (in thousands, except per share amounts):

14. STOCKHOLDERS’ EQUITY

Common equity transactions

Common stock repurchase program

On December 8, 2025, we announced that our Board of Directors authorized a new common stock repurchase program that

allows for the repurchase of up to$500.0 million of our common stock through December 31, 2026. This new program replaced our

prior stock repurchase program. As of the date of this report, no repurchases have been made under the new program and

$500.0 million remains available for future share repurchases.

ATM common stock offering program

In February 2024, we entered into an ATM common stock offering program that allows us to sell up to an aggregate of

$1.50 billion of our common stock.

During thenine months ended September 30, 2026, we had no activity under our ATM program. As of September 30, 2026,

the remaining aggregate amount available under our ATM program for future sales of common stock was $1.47 billion.

Dividends

During the three months ended March 31, 2026, we declared cash dividends on our common stock aggregating$125.5 million,

or$0.72 per share.

During the three months ended June 30, 2026, we declared cash dividends on our common stock aggregating$125.4 million,

or$0.72 per share.

During thethree months ended September 30, 2026, we declared cash dividends on our common stock aggregating

$125.4 million, or$0.72 per share.

Accumulated other comprehensive loss

The change in accumulated other comprehensive loss attributable to Alexandria Real Estate Equities, Inc.’s stockholders for

thenine months ended September 30, 2026 was due to net unrealized losses of $4.3 million, and included$12.3 million of unrealized

foreign currency translation losses related to our operations in Canada, partially offset by$8.0 million of unrealized gains resulting from

the changes in the fair value of our cross-currency swap agreements due to the weakening of the Canadian dollar. Refer to Note 11 –

“Hedge agreements” to our unaudited consolidated financial statements for additional information.

Common stock, preferred stock, and excess stock authorizations

Our charter authorizes the issuance of 400.0 million shares of common stock, of which 170.8 million shares were issued and

outstanding as of September 30, 2026. Our charter also authorizes the issuance of up to 100.0 million shares of preferred stock, none

of which were issued and outstanding as of September 30, 2026. In addition, 200.0 million shares of “excess stock”(as defined in our

charter) are authorized, none of which were issued and outstanding as of September 30, 2026.

15. SEGMENT INFORMATION

We are a life science REIT focused on developing, redeveloping, and operating properties that provide space for lease to

tenants primarily in the life science industry. Our properties are leased predominantly through triple-net lease agreements and share

key characteristics, including generic and reusable improvements, consistent lease structures, and business and financial strategy. All

properties are located within North America, predominantly in the U.S., and operate within a comparable regulatory environment.

Operating segments

Our Chief Operating Decision Maker (“CODM”), represented by our Executive Chairman and our Chief Executive Officer,

evaluates operating results at the geographic market level to assess performance and allocate resources. Our operating segments align

with our markets, including Greater Boston, San Diego, the San Francisco Bay Area, and Seattle, among others. Regular market

performance updates are provided directly to the CODM. These updates include each market’s net operating income (“NOI”), which

serves as the profit or loss measure used by the CODM for performance assessment and resource allocation. NOI provides useful

information regarding performance of each market as it reflects income and expenses incurred in connection with real estate operations

in each market. This metric enables the CODM to evaluate the profitability and performance of each market on a consistent and

comparable basis, supporting decisions on capital resource allocation, including in connection with development, redevelopment,

acquisition, and disposition activities in each market.

Evaluation of economic similarity and aggregation of operating segments

In accordance with the segment reporting accounting standard, we evaluate the economic similarity of our operating

segments. Seven of ournine operating segments exhibit consistent long-term economic characteristics, including similar historical long-

term NOI margins, which are also expected to remain similar in the future. Additionally, these markets share similar operational

characteristics, including nature of services provided (i.e., leasing, operating, developing, and redeveloping life science properties),

tenant base (i.e., a variety of tenants involved in the life science industry), methods of operation (i.e., consistent lease structures,

property management practices, and business strategies), and nature of the regulatory environment (consistent across North America,

where all our operating segments are located). Based on shared economic characteristics, we have aggregated ourseven operating

segments intoone reportable segment for segment reporting purposes. The remaining operating segments, which do not meet the

aggregation criteria and individually do not meet the quantitative thresholds to qualify as reportable segments, were included in the “all

other” category in the tables below.

The following table presents the reportable segment profit or loss measure, NOI, for thethree and nine months ended

September 30, 2026 and 2025 (in thousands):

Significant expenses included in the reportable segment profit or loss measure (i.e., NOI) are represented by the reportable

segment total rental operating expenses and are disclosed in the table above. These expenses primarily include property taxes, utilities,

repairs and maintenance, engineering, janitorial, and other costs.

15. SEGMENT INFORMATION (continued)

Presented below is the reconciliation of the reportable segment total revenues to the consolidated revenues, the reportable

segment total rental operating expenses to consolidated rental operations, and the reportable segment NOI to the consolidated net

income (in thousands):

The following table reconciles reportable segment investments in real estate to consolidated total assets (in thousands).

Reportable segment investments in real estate constitute the total assets of our reportable segment. Consolidated assets not allocated

to segments represent all asset line items presented in our consolidated balance sheets other than consolidated investments in real

estate.

16. SUBSEQUENT EVENTS

Sale of a partial interest in October 2026

In October 2026, we completed the sale of an approximately 29% noncontrolling interest in the consolidated real estate joint

venture that owns substantially all of Campus Point by Alexandria Megacampus for$475.0 million. Refer to Note 4 – “Consolidated and

unconsolidated real estate joint ventures” to our unaudited consolidated financial statements for additional information.
