Cash Available for Distribution: Cash Available for Distribution represents Core FFO, excluding non-rental property depreciation and amortization, straight-line rent adjustments, non-cash portion of interest expense, non-cash compensation expense, and deducts capital expenditures reimbursed by tenants, capital expenditures, leasing commissions and tenant improvements, and severance costs.

Cash Available for Distribution should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, these measurements should be compared with our reported net income or net loss in accordance with GAAP, as presented in our consolidated financial statements.

Cash Available for Distribution excludes, among other items, depreciation and amortization and capture neither the changes in the value of our buildings that result from use or market conditions of our buildings, all of which have real economic effects and could materially impact our results from operations, the utility of these measures as measures of our performance is limited. In addition, our calculation of Cash Available for Distribution may not be comparable to similarly titled measures disclosed by other REITs.

Cash Capitalization Rate: We define Cash Capitalization Rate as calculated by dividing (i) the Company’s estimate of year one cash net operating income from the applicable property’s operations stabilized for occupancy (post-lease-up for vacant properties), which does not include termination income, solar income, miscellaneous other income, capital expenditures, general and administrative costs, reserves, tenant improvements and leasing commissions, credit loss, or vacancy loss, by (ii) the GAAP purchase price plus estimated Acquisition Capital Expenditures. These Capitalization Rate estimates are subject to risks, uncertainties, and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties, and factors that are beyond our control, including those risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2022.

Cash Rent Change: We define Cash Rent Change as the percentage change in the base rent of the lease commenced during the period compared to the base rent of the Comparable Lease for assets included in the Operating Portfolio. The calculation compares the first base rent payment due after the lease commencement date compared to the base rent of the last monthly payment due prior to the termination of the lease, excluding holdover rent. Rent under gross or similar type leases are converted to a net rent based on an estimate of the applicable recoverable expenses.

Comparable Lease: We define a Comparable Lease as a lease in the same space with a similar lease structure as compared to the previous in-place lease, excluding new leases for space that was not occupied under our ownership.

Earnings before Interest, Taxes, Depreciation, and Amortization for Real Estate (EBITDAre), Adjusted EBITDAre, Annualized Adjusted EBITDAre, Run Rate Adjusted EBITDAre, and Annualized Run Rate Adjusted EBITDAre: We define EBITDAre in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). EBITDAre represents net income (loss) (computed in accordance with GAAP) before interest expense, interest and other income, tax, depreciation and amortization, gains or losses on the sale of rental property, and loss on impairments. Adjusted EBITDAre further excludes straight-line rent adjustments, non-cash compensation expense, amortization of above and below market leases, net, gain (loss) on involuntary conversion, debt extinguishment and modification expenses, and other non-recurring items.

We define Annualized Adjusted EBITDAre as Adjusted EBITDAre multiplied by four.

We define Run Rate Adjusted EBITDAre as Adjusted EBITDAre plus incremental Adjusted EBITDAre adjusted for a full period of acquisitions and dispositions. Run Rate Adjusted EBITDAre does not reflect the Company’s historical results and does not predict future results, which may be substantially different.

9

We define Annualized Run Rate Adjusted EBITDAre as Run Rate Adjusted EBITDAre excluding allowable one-time items multiplied by four plus allowable one-time items.

EBITDAre, Adjusted EBITDAre, and Run Rate Adjusted EBITDAre should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, EBITDAre, Adjusted EBITDAre, and Run Rate Adjusted EBITDAre should be compared with our reported net income or net loss in accordance with GAAP, as presented in our consolidated financial statements. We believe that EBITDAre, Adjusted EBITDAre, and Run Rate Adjusted EBITDAre are helpful to investors as supplemental measures of the operating performance of a real estate company because they are direct measures of the actual operating results of our properties. We also use these measures in ratios to compare our performance to that of our industry peers.

Funds from Operations (FFO) and Core FFO: We define FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of depreciable operating property, gains (losses) from sales of land, impairment write-downs of depreciable real estate, rental property depreciation and amortization (excluding amortization of deferred financing costs and fair market value of debt adjustment) and after adjustments for unconsolidated partnerships and joint ventures. Core FFO excludes amortization of above and below market leases, net, debt extinguishment and modification expenses, gain (loss) on involuntary conversion, gain (loss) on swap ineffectiveness, and non-recurring other expenses.

None of FFO or Core FFO should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, these measurements should be compared with our reported net income or net loss in accordance with GAAP, as presented in our consolidated financial statements. We use FFO as a supplemental performance measure because it is a widely recognized measure of the performance of REITs. FFO may be used by investors as a basis to compare our operating performance with that of other REITs. We and investors may use Core FFO similarly as FFO.

However, because FFO and Core FFO exclude, among other items, depreciation and amortization and capture neither the changes in the value of our buildings that result from use or market conditions of our buildings, all of which have real economic effects and could materially impact our results from operations, the utility of these measures as measures of our performance is limited. In addition, other REITs may not calculate FFO in accordance with the NAREIT definition as we do, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. Similarly, our calculation of Core FFO may not be comparable to similarly titled measures disclosed by other REITs.

GAAP: We define GAAP as generally accepted accounting principles in the United States.

Liquidity: We define Liquidity as the amount of aggregate undrawn nominal commitments the Company could immediately borrow under the Company’s unsecured debt instruments, consistent with the financial covenants, plus unrestricted cash balances.

Market: We define Market as the market defined by CBRE-EA based on the building address. If the building is located outside of a CBRE-EA defined market, the city and state is reflected.

Net Debt: We define Net Debt as the outstanding principal balance of the Company's total debt, less cash and cash equivalents.

Net operating income (NOI), Cash NOI, and Run Rate Cash NOI: We define NOI as rental income, including reimbursements, less property expenses, which excludes depreciation, amortization, loss on impairments, general and administrative expenses, interest expense, interest income, gain (loss) on involuntary conversion, debt extinguishment and modification expenses, gain on sales of rental property, and other expenses.

We define Cash NOI as NOI less rental property straight-line rent adjustments and less amortization of above and below market leases, net.

10

We define Run Rate Cash NOI as Cash NOI plus Cash NOI adjusted for a full period of acquisitions and dispositions, less cash termination income, solar income and revenue associated with one-time tenant reimbursements of capital expenditures. Run Rate Cash NOI does not reflect the Company’s historical results and does not predict future results, which may be substantially different.

We consider NOI, Cash NOI and Run Rate Cash NOI to be appropriate supplemental performance measures to net income because we believe they help us, and investors understand the core operations of our buildings. None of these measures should be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, these measurements should be compared with our reported net income or net loss in accordance with GAAP, as presented in our consolidated financial statements. Further, our calculations of NOI, Cash NOI and Run Rate NOI may not be comparable to similarly titled measures disclosed by other REITs.

Occupancy Rate: We define Occupancy Rate as the percentage of total leasable square footage for which either revenue recognition has commenced in accordance with GAAP or the lease term has commenced as of the close of the reporting period, whichever occurs earlier.

Operating Portfolio: We define the Operating Portfolio as all buildings that were acquired stabilized or have achieved Stabilization. The Operating Portfolio excludes non-core flex/office buildings, buildings contained in the Value Add Portfolio, and buildings classified as held for sale.

Pipeline: We define Pipeline as a point in time measure that includes all of the transactions under consideration by the Company’s acquisitions group that have passed the initial screening process. The pipeline also includes transactions under contract and transactions with non-binding LOIs.

Renewal Lease: We define a Renewal Lease as a lease signed by an existing tenant to extend the term for 12 months or more, including (i) a renewal of the same space as the current lease at lease expiration, (ii) a renewal of only a portion of the current space at lease expiration, or (iii) an early renewal or workout, which ultimately does extend the original term for 12 months or more.

Retention: We define Retention as the percentage determined by taking Renewal Lease square footage commencing in the period divided by square footage of leases expiring in the period for assets included in the Operating Portfolio.

Same Store: We define Same Store properties as properties that were in the Operating Portfolio for the entirety of the comparative periods presented. The results for Same Store properties exclude termination fees, solar income, and revenue associated with one-time tenant reimbursements of capital expenditures. Same Store properties exclude Operating Portfolio properties with expansions placed into service or transferred from the Value Add Portfolio to the Operating Portfolio after December 31, 2021.

Stabilization: We define Stabilization for assets under development or redevelopment to occur as the earlier of achieving 90% occupancy or 12 months after completion. Stabilization for assets that were acquired and immediately added to the Value Add Portfolio occurs under the following:

•if acquired with less than 75% occupancy as of the acquisition date, Stabilization will occur upon the earlier of achieving 90% occupancy or 12 months from the acquisition date;

•if acquired and will be less than 75% occupied due to known move-outs within two years of the acquisition date, Stabilization will occur upon the earlier of achieving 90% occupancy after the known move-outs have occurred or 12 months after the known move-outs have occurred.

Straight-Line Capitalization Rate: We define Straight-Line Capitalization Rate as calculated by dividing (i) the Company’s estimate of average annual net operating income from the applicable property’s operations stabilized for occupancy (post-lease-up for vacant properties), which does not include termination income, solar income, miscellaneous other income, capital expenditures, general and administrative costs, reserves, tenant improvements and leasing commissions, credit loss, or vacancy loss, by (ii) the GAAP purchase price plus estimated Acquisition Capital Expenditures. These Capitalization Rate estimates are subject to risks, uncertainties, and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties, and factors that are beyond our control, including those risk factors contained in our Annual Report on Form 10-K for the year ended December 31, 2022.

11

Straight-Line Rent Change (SL Rent Change): We define SL Rent Change as the percentage change in the average monthly base rent over the term of the lease that commenced during the period compared to the Comparable Lease for assets included in the Operating Portfolio. Rent under gross or similar type leases are converted to a net rent based on an estimate of the applicable recoverable expenses, and this calculation excludes the impact of any holdover rent.

Value Add Portfolio: We define the Value Add Portfolio as properties that meet any of the following criteria:

•less than 75% occupied as of the acquisition date

•will be less than 75% occupied due to known move-outs within two years of the acquisition date;

•out of service with significant physical renovation of the asset;

•development.

Weighted Average Lease Term: We define Weighted Average Lease Term as the contractual lease term in years as of the lease start date weighted by square footage. Weighted Average Lease Term related to acquired assets reflects the remaining lease term in years as of the acquisition date weighted by square footage.
