1.ORGANIZATION AND BASIS OF PRESENTATION

Alexandria Real Estate Equities, Inc. (NYSE: ARE), an S&P 500® life science REIT, is the pioneer of the life science real estate

niche since its founding in 1994. Alexandria is the preeminent and longest-tenured owner, operator, and developer of collaborative

Megacampus™ ecosystems in AAA life science innovation cluster locations, including Greater Boston, the San Francisco Bay Area,

San Diego, Seattle, Maryland, Research Triangle, and New York City. As of March 31, 2026, Alexandria has a total market capitalization

of $20.44 billion and an asset base that includes 35.8 million RSF of operating properties and 3.4 million RSF of Class A/A+ properties

undergoing construction. As used in this quarterly report on Form 10-Q, references to the “Company,” “Alexandria,” “ARE,” “we,” “us,”

and “our” refer to Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries. The accompanying unaudited consolidated

financial statements include the accounts of Alexandria Real Estate Equities, Inc. and its consolidated subsidiaries. All significant

intercompany balances and transactions have been eliminated.

We have prepared the accompanying interim consolidated financial statements in accordance with GAAP and in conformity

with the rules and regulations of the SEC. In our opinion, these interim consolidated financial statements presented herein reflect all

adjustments, of a normal recurring nature, that are necessary to fairly present the interim consolidated financial statements. The results

of operations for the interim period are not necessarily indicative of the results that may be expected for the year ending December 31,

2026. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial

statements and the notes thereto included in our annual report on Form 10-K for the year ended December 31, 2025. Any references to

our total market capitalization, number or quality of buildings or tenants, quality of location, square footage, number of leases, or

occupancy percentage, and any amounts derived from these values in these notes to consolidated financial statements are outside the

scope of our independent registered public accounting firm’s procedures.

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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 are 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 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Investments in real estate

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

needs to 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

needs to 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 there is reasonable assurance that such bargain purchase option will be exercised,

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.

Depreciation and amortization

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. The values of the 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

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 March 31, 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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%. 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 policymaking 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 (loss) 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 (loss) 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 (loss) 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (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 (loss) 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 the three months ended March 31, 2026 and 2025

(in thousands):


	Three Months Ended March 31,
	2026	2025
Income from rentals:
Revenues subject to the lease accounting standard:
Operating leases	$640,659	$731,421
Direct financing and sales-type leases	964	810
Revenues subject to the lease accounting standard	641,623	732,231
Revenues subject to the revenue recognition accounting standard	11,390	10,944
Income from rentals	653,013	743,175
Other income	18,009	14,983
Total revenues	$671,022	$758,158

During the three months ended March 31, 2026 and 2025, revenues that were subject to the lease accounting standard

aggregated $641.6 million, or 95.6%, and $732.2 million, or 96.6%, of our total revenue, respectively. Our other income consisted

primarily of management 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 significant accounting policies” to our unaudited consolidated financial statements.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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

not meet any of the criteria, we account for the lease 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 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 from our tenants of future lease payments 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 March 31, 2026 and December 31, 2025, our general allowance balance aggregated

$14.3 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. Our net investment is reduced over time as lease payments are received.

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

significant accounting policies” to our unaudited consolidated financial statements.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 the three months ended March 31, 2026 included $11.4 million 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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

additional details.

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

significant accounting policies” to our unaudited consolidated financial statements.

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 payments

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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 not

deemed to be liabilities as they 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. 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.

2.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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 greater 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: purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depreciation or depletion.

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 consolidated financial statements.

3.INVESTMENTS IN REAL ESTATE

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

Assets held for sale

As of March 31, 2026, we had 19 operating properties aggregating 1.4 million RSF and land parcels aggregating 1.6 million SF

that were classified as held for sale.

The disposal of 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 individual 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 a discontinued operation. 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 March 31, 2026 and December 31, 2025 (in thousands):


	March 31, 2026	December 31, 2025
Investments in real estate, less accumulated depreciation	$493,161	$556,679
Other assets	41,409	37,859
Total assets	534,570	594,538

Total liabilities	(11,841)	(12,235)
Total accumulated other comprehensive loss	(181)	(566)
Net assets classified as held for sale	$522,548	$581,737

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

consolidated financial statements.

Sales of real estate assets and impairment of real estate

Impairment of real estate

During the three months ended March 31, 2026, we recognized impairment charges aggregating $5.5 million, classified within

impairment of real estate in our consolidated statement of operations. The impairment primarily reflects an incremental charge

recognized in connection with the amendment of the sales agreement during the three months ended March 31, 2026 related to our

Canada portfolio, which is classified as held for sale as of March 31, 2026.

3.INVESTMENTS IN REAL ESTATE (continued)

Other

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 $180.6 million as of March 31, 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. 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 $180.6 million as of March 31, 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

present as of March 31, 2026.

Separately from, and not part of, the pending litigation related to the Option Parcel, on April 21, 2026, EDC, on behalf of H+H,

the landlord, and itself, lease administrator, delivered 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 to up to $2,000. ARE disputes the allegations set forth

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

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 March 31, 2026, our real estate joint ventures held the following properties:


	Property(1)	Market	Submarket	Our Ownership Interest

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

(4)The noncontrolling interest share of our joint venture partner is anticipated to decrease to 25%, as we expect to fund the majority of future construction costs at the

campus until our ownership interest increases to 75%, after which future capital would be contributed pro rata with our partner.

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

(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 that 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.

4.CONSOLIDATED AND UNCONSOLIDATED REAL ESTATE JOINT VENTURES (continued)

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

Consolidated real estate joint ventures

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 converted into a redeemable noncontrolling interest that accrued a fixed 4.05% annual

preferred return (“distributions”). In January 2026, the partner exercised its option to require us to purchase its preferred interest, and

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

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.

4.CONSOLIDATED AND UNCONSOLIDATED REAL ESTATE JOINT VENTURES (continued)

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


	March 31, 2026	December 31, 2025
Investments in real estate	$5,797,860	$6,129,668
Cash and cash equivalents	185,263	258,755
Other assets	724,923	712,154
Total assets	$6,708,046	$7,100,577

Secured note payable	$—	$—
Other liabilities	287,285	324,513
Total liabilities	287,285	324,513
Redeemable noncontrolling interests	—	49,554
Alexandria Real Estate Equities, Inc.’s share of equity	2,800,347	3,098,932
Noncontrolling interests’ share of equity	3,620,414	3,627,578
Total liabilities and equity	$6,708,046	$7,100,577

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. None of our consolidated VIEs’ assets have restrictions that limit

their use to settle specific obligations of the VIE. There are no creditors or other partners of our consolidated VIEs that have recourse to

our general credit, and our maximum exposure to our consolidated VIEs is limited to our variable interests in each VIE.

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 the three months ended March 31, 2026 and 2025, we distributed

$60.1 million and $66.0 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 March 31,

2026 and December 31, 2025 (in thousands):


Property	March 31, 2026	December 31, 2025
1655 and 1725 Third Street	$19,333	$19,484
101 West Dickman Street	9,666	9,669
Other	1,521	1,524
	$30,520	$30,677

Our maximum exposure to our 1655 and 1725 Third Street unconsolidated VIE is limited to our investment in this VIE. With

respect to our unconsolidated real estate joint venture at 101 West Dickman Street, we guarantee up to $6.7 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 March 31, 2026 (dollars in thousands):


					Interest Rate(1)	At 100%		Our Share
Unconsolidated Joint Venture	Maturity Date		Stated Rate		Interest Rate(1)	Aggregate Commitment	Debt Balance(2)	Our Share
101 West Dickman Street		10/29/26	SOFR+1.95%	(3)	5.68%	$26,750	$19,048	58.4%

						$526,750	$516,015

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

(2)Represents outstanding principal, net of unamortized deferred financing costs, as of March 31, 2026.

(3)This loan is subject to a fixed 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 March 31, 2026, we had 339 properties aggregating 35.8 million operating RSF in key cluster locations, including

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

on developing Class A/A+ properties in AAA life science 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 March 31, 2026, all leases in which we are the lessor were classified as operating leases, with the exception of one

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

Operating leases

As of March 31, 2026, our 339 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, representing two 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 the two land parcels is 66.7 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 6.9 years and 18.5 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 the tenant to extend their lease 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 March 31, 2026 are outlined in the table below (in thousands):


Year		Amount
2026		$1,220,483
2027		1,494,928
2028		1,359,084
2029		1,261,862
2030		1,193,688
Thereafter		7,152,763
Total		$13,682,808

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.

5.LEASES (continued)

Direct financing and sales-type leases

As of March 31, 2026, we have one direct financing lease agreement, with a net investment balance of $42.8 million, for a

parking structure with a remaining lease term of 66.7 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 March 31, 2026, we also have one sales-type lease for a property in the Seattle market. As of March 31, 2026, the net

investment in this lease is $16.6 million. At the end of the lease term in 2026, the property under this lease will transfer to the tenant for

a sales price of approximately $18.0 million.

As of March 31, 2026, our estimated provision for expected credit loss related to our direct financing lease and sales-type

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

credit loss 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 significant

accounting policies” to our unaudited consolidated financial statements.

The components of our aggregate net investment in our direct financing and sales-type leases as of March 31, 2026 and

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


	March 31, 2026	December 31, 2025
Gross investment in direct financing and sales-type leases	$265,618	$265,839

5.LEASES (continued)

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 operating lease agreements in which we are the lessee consisting of ground and office leases. 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 March 31, 2026, the present value of the remaining contractual payments aggregating $767.2 million under our operating

lease agreements, including our extension options that we are reasonably certain to exercise, was $358.6 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 $693.8 million. As of March 31, 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 March 31, 2026 included leases for 31 of our properties, which accounted for approximately 9%

of our total number of properties. Excluding one ground lease that expires in 2036 related to one operating property with a net book

value of $5.0 million as of March 31, 2026, 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.

5.LEASES (continued)

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 March 31, 2026 is in the table below (in thousands):


Year		Total
2026		$17,206
2027		21,650
2028		21,318
2029		20,825
2030		20,743
Thereafter		665,496
Total future payments under our operating leases in which we are the lessee		767,238
Effect of discounting		(408,628)
Operating lease liability		$358,610

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 the three months ended March 31, 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 $6.2 million and $144.6 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 extension to 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 the three months ended March 31, 2026 and 2025, our costs for operating leases in which we are the lessee were as

follows (in thousands):


	Three Months Ended March 31,
	2026	2025
Gross operating lease costs	$8,417	$12,359
Capitalized lease costs	(759)	(693)
Expenses for operating leases in which we are the lessee	$7,658	$11,666

6. CASH, CASH EQUIVALENTS, AND RESTRICTED CASH

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

thousands):


	March 31, 2026	December 31, 2025
Cash and cash equivalents	$418,720	$549,062
Restricted cash:
Development escrows	2,129	2,142

	4,665	4,693
Total	$423,385	$553,755

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%. 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 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 March 31, 2026, we had nine investments in limited partnerships maintaining specific ownership accounts for each

investor, which were accounted for under the equity method. These investments aggregated $367.9 million. Our ownership interest in

each of these nine investments was greater than 5%.
