155ALEXANDRIA REAL ESTATE EQUITIES, INC. | Proprietary | All Rights Reserved © 2024 DEFINITIONS AND NON-GAAP RECONCILIATIONS Adjusted EBITDA and Adjusted EBITDA margin We use Adjusted EBITDA as a supplemental performance measure of our operations, for financial and operational decision-making, and as a supplemental means of evaluating period-to-period comparisons on a consistent basis. Adjusted EBITDA is calculated as earnings before interest, taxes, depreciation, and amortization (“EBITDA”), excluding stock compensation expense, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, impairments of real estate, and significant termination fees. Adjusted EBITDA also excludes unrealized gains or losses and significant realized gains or losses and impairments that result from our non-real estate investments. These nonreal estate investment amounts are classified in our consolidated statements of operations outside of total revenues. We believe Adjusted EBITDA provides investors with relevant and useful information as it allows investors to evaluate the operating performance of our business activities without having to account for differences recognized because of investing and financing decisions related to our real estate and non-real estate investments, our capital structure, capital market transactions, and variances resulting from the volatility of market conditions outside of our control. For example, we exclude gains or losses on the early extinguishment of debt to allow investors to measure our performance independent of our indebtedness and capital structure. We believe that adjusting for the effects of impairments and gains or losses on sales of real estate, significant impairments and realized gains or losses on non-real estate investments, and significant termination fees allows investors to evaluate performance from period to period on a consistent basis without having to account for differences recognized because of investing and financing decisions related to our real estate and non-real estate investments or other corporate activities that may not be representative of the operating performance of our properties. In addition, we believe that excluding charges related to stock compensation and unrealized gains or losses facilitates for investors a comparison of our business activities across periods without the volatility resulting from market forces outside of our control. Adjusted EBITDA has limitations as a measure of our performance. Adjusted EBITDA does not reflect our historical expenditures or future requirements for capital expenditures or contractual commitments. While Adjusted EBITDA is a relevant measure of performance, it does not represent net income (loss) or cash flows from operations calculated and presented in accordance with GAAP, and it should not be considered as an alternative to those indicators in evaluating performance or liquidity. We are not able to forecast fourth quarter net income without unreasonable effort and therefore do not provide a reconciliation for Adjusted EBITDA on a forward-looking basis. This is due to the inherent difficulty of forecasting the timing and/or amount of items that depend on market conditions outside of our control, including the timing of dispositions, capital events, and financing decisions, as well as quarterly components such as gain on sales of real estate, unrealized gains or losses on non-real estate investments, impairment of real estate, and impairment of non-real estate investments. Our attempt to predict these amounts may produce significant but inaccurate estimates, which would be potentially misleading for our investors. Annual rental revenue Annual rental revenue represents the annualized fixed base rental obligations, calculated in accordance with GAAP, including the amortization of deferred revenue related to tenant-funded and -built landlord improvements, for leases in effect as of the end of the period, related to our operating RSF. Annual rental revenue is presented using 100% of the annual rental revenue from our consolidated properties and our share of annual rental revenue for our unconsolidated real estate joint ventures. Annual rental revenue per RSF is computed by dividing annual rental revenue by the sum of 100% of the RSF of our consolidated properties and our share of the RSF of properties held in unconsolidated real estate joint ventures. As of September 30, 2024, approximately 93% of our leases (on an annual rental revenue basis) were triple net leases, which require tenants to pay substantially all real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses (including increases thereto) in addition to base rent. Annual rental revenue excludes these operating expenses recovered from our tenants. Amounts recovered from our tenants related to these operating expenses, along with base rent, are classified in income from rentals in our consolidated statements of operations. Capitalization rates Capitalization rates are calculated based on net operating income and net operating income (cash basis) annualized, excluding lease termination fees, on stabilized operating assets for the quarter preceding the date on which the property is sold, or near-term prospective net operating income. Capitalized interest We capitalize interest cost as a cost of a project during periods for which activities necessary to develop, redevelop, or reposition a project for its intended use are ongoing, provided that expenditures for the asset have been made and interest cost has been incurred. Activities necessary to develop, redevelop, or reposition a project include pre- construction activities such as entitlements, permitting, design, site work, and other activities preceding commencement of construction of aboveground building improvements. The advancement of pre-construction efforts is focused on reducing the time required to deliver projects to prospective tenants. These critical activities add significant value for future ground-up development and are required for the vertical construction of buildings. If we cease activities necessary to prepare a project for its intended use, interest costs related to such project are expensed as incurred.

156ALEXANDRIA REAL ESTATE EQUITIES, INC. | Proprietary | All Rights Reserved © 2024 DEFINITIONS AND NON-GAAP RECONCILIATIONS Class A/A+ properties and AAA locations Class A/A+ properties are properties clustered in AAA locations that provide innovative tenants with highly dynamic and collaborative environments that enhance their ability to successfully recruit and retain world-class talent and inspire productivity, efficiency, creativity, and success. Class A/A+ properties generally command higher annual rental rates than other classes of similar properties. AAA locations are in close proximity to concentrations of specialized skills, knowledge, institutions, and related businesses. Such locations are generally characterized by high barriers to entry for new landlords, high barriers to exit for tenants, and a limited supply of available space. Competitive supply Represents the total rentable square footage of laboratory space under development or redevelopment that (i) is available for direct lease and (ii) we believe is competitive with our laboratory space within a given submarket. Total competitive supply excludes owner-user space. Development, redevelopment, and pre-construction A key component of our business model is our disciplined allocation of capital to the development and redevelopment of new Class A/A+ properties, and property enhancements identified during the underwriting of certain acquired properties, located in collaborative Megacampus ecosystems in AAA life science innovation clusters. These projects are generally focused on providing high-quality, generic, and reusable spaces that meet the real estate requirements of a wide range of tenants. Upon completion, each development and redevelopment project is expected to generate increases in rental income, net operating income, and cash flows. Our development and redevelopment projects are generally in locations that are highly desirable to high-quality entities, which we believe results in higher occupancy levels, longer lease terms, higher rental income, higher returns, and greater long-term asset value. Development projects generally consist of the ground-up development of generic and reusable laboratories. Redevelopment projects consist of the permanent change in use of acquired office, warehouse, or shell space into laboratory space. We generally will not commence new development projects for aboveground construction of new Class A/A+ laboratory space without first securing significant pre-leasing for such space, except when there is solid market demand for high-quality Class A/A+ properties. Priority anticipated projects are those most likely to commence future ground-up development or first-time conversion from non-laboratory space to laboratory space prior to our other future projects, pending market conditions and leasing negotiations. Pre-construction activities include entitlements, permitting, design, site work, and other activities preceding commencement of construction of aboveground building improvements. The advancement of pre-construction efforts is focused on reducing the time required to deliver projects to prospective tenants. These critical activities add significant value for future ground-up development and are required for the vertical construction of buildings. Ultimately, these projects will provide high-quality facilities and are expected to generate significant revenue and cash flows. Development, redevelopment, and pre-construction spending also includes the following costs: (i) amounts to bring certain acquired properties up to market standard and/or other costs identified during the acquisition process (generally within two years of acquisition) and (ii) permanent conversion of space for highly flexible, move-in-ready laboratory space to foster the growth of promising early- and growth-stage life science companies. Revenue-enhancing and repositioning capital expenditures represent spending to reposition or significantly change the use of a property, including through improvement in the asset quality from Class B to Class A/A+. Non-revenue-enhancing capital expenditures represent costs required to maintain the current revenues of a stabilized property, including the associated costs for renewed and re-leased space. Non-revenue-enhancing capital expenditures represent costs required to maintain the current revenues of a stabilized property, including the associated costs for renewed and re-leased space.

157ALEXANDRIA REAL ESTATE EQUITIES, INC. | Proprietary | All Rights Reserved © 2024 DEFINITIONS AND NON-GAAP RECONCILIATIONS Dividend payout ratio (common stock) Dividend payout ratio (common stock) is the ratio of the absolute dollar amount of dividends on our common stock (shares of common stock outstanding on the respective record dates multiplied by the related dividend per share) to funds from operations attributable to Alexandria’s common stockholders – diluted, as adjusted. Fixed-charge coverage ratio Fixed-charge coverage ratio is a non-GAAP financial measure representing the ratio of Adjusted EBITDA to cash interest and fixed charges. We believe that this ratio is useful to investors as a supplemental measure of our ability to satisfy fixed financing obligations and preferred stock dividends. Cash interest is equal to interest expense calculated in accordance with GAAP plus capitalized interest, less amortization of loan fees and debt premiums (discounts). We are not able to forecast fourth quarter net income without unreasonable effort and therefore do not provide a reconciliation for fixed-charge coverage ratio on a forward- looking basis. This is due to the inherent difficulty of forecasting the timing and/or amount of items that depend on market conditions outside of our control, including the timing of dispositions, capital events, and financing decisions, as well as quarterly components such as gain on sales of real estate, unrealized gains or losses on non-real estate investments, impairment of real estate, and impairment of non-real estate investments. Our attempt to predict these amounts may produce significant but inaccurate estimates, which would be potentially misleading for our investors. Funds from operations and funds from operations, as adjusted, attributable to Alexandria’s common stockholders GAAP-basis accounting for real estate assets utilizes historical cost accounting and assumes that real estate values diminish over time. In an effort to overcome the difference between real estate values and historical cost accounting for real estate assets, the Nareit Board of Governors established funds from operations as an improved measurement tool. Since its introduction, funds from operations has become a widely used non-GAAP financial measure among equity REITs. We believe that funds from operations is helpful to investors as an additional measure of the performance of an equity REIT. Moreover, we believe that funds from operations, as adjusted, allows investors to compare our performance to the performance of other real estate companies on a consistent basis, without having to account for differences recognized because of real estate acquisition and disposition decisions, financing decisions, capital structure, capital market transactions, variances resulting from the volatility of market conditions outside of our control, or other corporate activities that may not be representative of the operating performance of our properties. The 2018 White Paper published by the Nareit Board of Governors (the “Nareit White Paper”) defines funds from operations as net income (computed in accordance with GAAP), excluding gains or losses on sales of real estate, and impairments of real estate, plus depreciation and amortization of operating real estate assets, and after adjustments for our share of consolidated and unconsolidated partnerships and real estate joint ventures. Impairments represent the write-down of assets when fair value over the recoverability period is less than the carrying value due to changes in general market conditions and do not necessarily reflect the operating performance of the properties during the corresponding period. We compute funds from operations, as adjusted, as funds from operations calculated in accordance with the Nareit White Paper, excluding significant gains, losses, and impairments realized on non-real estate investments, unrealized gains or losses on non-real estate investments, impairment of real estate primarily consisting of pre-acquisition costs incurred in connection with acquisitions we decided to no longer pursue, gains or losses on early extinguishment of debt, significant termination fees, acceleration of stock compensation expense due to the resignations of executive officers, deal costs, the income tax effect related to such items, and the amount of such items that is allocable to our unvested restricted stock awards. We compute the amount that is allocable to our unvested restricted stock awards using the two-class method. Under the two-class method, we allocate net income (after amounts attributable to noncontrolling interests) to common stockholders and to unvested restricted stock awards by applying the respective weighted- average shares outstanding during each quarter-to-date and year-to-date period. This may result in a difference of the summation of the quarter-to-date and year-to-date amounts. Neither funds from operations nor funds from operations, as adjusted, should be considered as alternatives to net income (determined in accordance with GAAP) as indications of financial performance, or to cash flows from operating activities (determined in accordance with GAAP) as measures of liquidity, nor are they indicative of the availability of funds for our cash needs, including our ability to make distributions.

158ALEXANDRIA REAL ESTATE EQUITIES, INC. | Proprietary | All Rights Reserved © 2024 DEFINITIONS AND NON-GAAP RECONCILIATIONS Initial stabilized yield (unlevered) Initial stabilized yield is calculated as the estimated amounts of net operating income at stabilization divided by our investment in the property. For this calculation, we exclude any tenant funded and -built landlord improvements from our investment in the property. Our initial stabilized yield excludes the benefit of leverage. Our cash rents related to our development and redevelopment projects are generally expected to increase over time due to contractual annual rent escalations. Our estimates for initial stabilized yields, initial stabilized yields (cash basis), and total costs at completion represent our initial estimates at the commencement of the project. We expect to update this information upon completion of the project, or sooner if there are significant changes to the expected project yields or costs. - Initial stabilized yield reflects rental income, including contractual rent escalations and any rent concessions over the term(s) of the lease(s), calculated on a straight-line basis, and any amortization of deferred revenue related to tenant-funded and -built landlord improvements. - Initial stabilized yield (cash basis) reflects cash rents at the stabilization date after initial rental concessions, if any, have elapsed and our total cash investment in the property. Investment-grade or publicly traded large cap tenants Investment-grade or publicly traded large cap tenants represent tenants that are investment-grade-rated or publicly traded companies with an average daily market capitalization greater than $10 billion for the twelve months ended September 30, 2024, as reported by Bloomberg Professional Services. Credit ratings from Moody’s Ratings and S&P Global Ratings reflect credit ratings of the tenant’s parent entity, and there can be no assurance that a tenant’s parent entity will satisfy the tenant’s lease obligation upon such tenant’s default. We monitor the credit quality and related material changes of our tenants. Material changes that cause a tenant’s market capitalization to decrease below $10 billion, which are not immediately reflected in the twelve-month average, may result in their exclusion from this measure. Megacampus™ A Megacampus is a cluster campus that consists of approximately 1 million RSF or more, including operating, active development/redevelopment, and land RSF less operating RSF expected to be demolished. Net cash provided by operating activities after dividends Net cash provided by operating activities after dividends includes the deduction for distributions to noncontrolling interests. For purposes of this calculation, changes in operating assets and liabilities are excluded as they represent timing differences. Net debt and preferred stock to Adjusted EBITDA Net debt and preferred stock to Adjusted EBITDA is a non-GAAP financial measure that we believe is useful to investors as a supplemental measure of evaluating our balance sheet leverage. Net debt and preferred stock is equal to the sum of total consolidated debt less cash, cash equivalents, and restricted cash, plus preferred stock outstanding as of the end of the period. Refer to the definition of Adjusted EBITDA. We are not able to forecast fourth quarter net income without unreasonable effort and therefore do not provide a reconciliation for net debt and preferred stock to Adjusted EBITDA on a forward-looking basis. This is due to the inherent difficulty of forecasting the timing and/or amount of items that depend on market conditions outside of our control, including the timing of dispositions, capital events, and financing decisions, as well as quarterly components such as gain on sales of real estate, unrealized gains or losses on non- real estate investments, impairment of real estate, and impairment of non-real estate investments. Our attempt to predict these amounts may produce significant but inaccurate estimates, which would be potentially misleading for our investors.

159ALEXANDRIA REAL ESTATE EQUITIES, INC. | Proprietary | All Rights Reserved © 2024 DEFINITIONS AND NON-GAAP RECONCILIATIONS Net operating income and net operating income (cash basis) Net operating income is a non-GAAP financial measure calculated as net income, the most directly comparable financial measure calculated and presented in accordance with GAAP, excluding equity in the earnings of our unconsolidated real estate joint ventures, general and administrative expenses, interest expense, depreciation and amortization, impairments of real estate, gains or losses on early extinguishment of debt, gains or losses on sales of real estate, and investment income or loss. We believe net operating income provides useful information to investors regarding our financial condition and results of operations because it primarily reflects those income and expense items that are incurred at the property level. Therefore, we believe net operating income is a useful measure for investors to evaluate the operating performance of our consolidated real estate assets. Net operating income on a cash basis is net operating income adjusted to exclude the effect of straight-line rent, amortization of acquired above- and below-market lease revenue, and amortization of deferred revenue related to tenant-funded and -built landlord improvements adjustments required by GAAP. We believe that net operating income on a cash basis is helpful to investors as an additional measure of operating performance because it eliminates straight-line rent revenue and the amortization of acquired above- and below- market leases and tenant-funded and -built landlord improvements. Operating statistics We present certain operating statistics related to our properties, including number of properties, RSF, occupancy percentage, leasing activity, and contractual lease expirations as of the end of the period. We believe these measures are useful to investors because they facilitate an understanding of certain trends for our properties. We compute the number of properties, RSF, occupancy percentage, leasing activity, and contractual lease expirations at 100%, excluding RSF at properties classified as held for sale, for all properties in which we have an investment, including properties owned by our consolidated and unconsolidated real estate joint ventures. Same property Same property refers to all consolidated properties that were fully operating for the entirety of the comparative periods presented. Properties that underwent development or redevelopment at any time during the comparative periods, unconsolidated real estate joint ventures, properties classified as held for sale, and corporate entities (legal entities performing general and administrative functions) are excluded from same property results. Additionally, termination fees, if any, are excluded from the results of same properties. Total equity capitalization Total equity capitalization is equal to the outstanding shares of common stock multiplied by the closing price on the last trading day at the end of each period presented. Total market capitalization Total market capitalization is equal to the sum of total equity capitalization and total debt. Weighted-average interest rate for capitalization of interest The weighted-average interest rate required for calculating capitalization of interest pursuant to GAAP represents a weighted-average rate as of the end of the applicable period, based on the rates applicable to borrowings outstanding during the period, including expense/income related to interest rate hedge agreements, amortization of loan fees, amortization of debt premiums (discounts), and other bank fees. A separate calculation is performed to determine our weighted-average interest rate for capitalization for each month. The rate will vary each month due to changes in variable interest rates, outstanding debt balances, the proportion of variable-rate debt to fixed-rate debt, the amount and terms of interest rate hedge agreements, and the amount of loan fee and premium (discount) amortization.
