Definitions + Glossary 29 Definitions + Glossary ACQUISITION COSTS Transaction costs expensed in connection with executed or anticipated acquisitions of operating properties. ADJUSTED BOOK Total assets presented on our consolidated balance sheet, net of lease liabilities associated with property right-of-use assets, and excluding the effect of cash and cash equivalents, accumulated depreciation on real estate properties, accumulated amortization of intangible assets on real estate acquisitions, accumulated amortization of deferred leasing costs and unconsolidated real estate joint ventures (“JVs”) cash and cash equivalents, liabilities, and accumulated depreciation and amortization (of intangibles on property acquisitions and deferred leasing costs) allocable to our ownership interest in the JVs. ADJUSTED EARNINGS BEFORE INTEREST, INCOME TAXES, DEPRECIATION AND AMORTIZATION (“ADJUSTED EBITDA”) Net income or loss adjusted for the effects of interest expense, depreciation and amortization, gain on sales and impairment losses of real estate and investments in unconsolidated real estate JVs, gain or loss on early extinguishment of debt, loss on interest rate derivatives, net gain or loss on other investments, credit loss expense or recoveries, operating property acquisition costs, income taxes, business development expenses, demolition costs on redevelopment and nonrecurring improvements, executive transition costs, and certain other expenses that we believe are not relevant to an investor's evaluation of our ability to repay debt. Adjusted EBITDA also includes adjustments to net income or loss for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. ANNUALIZED RENTAL REVENUE (“ARR”) The monthly contractual base rent as of the reporting date (ignoring free rent then in effect and rent associated with tenant funded landlord assets) multiplied by 12, plus the estimated annualized expense reimbursements under existing leases for occupied space. With regard to properties owned through unconsolidated real estate JVs, we include the portion of ARR allocable to COPT Defense’s ownership interest. In instances in which we report ARR per occupied square foot, the measure excludes revenue from leases not associated with our buildings. ATFP Anti-terrorism force protection. AVERAGE ESCALATIONS Leasing statistic used to report average increase in rental rates over lease terms for leases with a term of greater than one-year. BALTIMORE/WASHINGTON REGION Counties that comprise the Fort Meade/Baltimore Washington Corridor. As of June 30, 2026, 96 of COPT Defense’s properties were located within this defined region. Please refer to page 12 of COPT Defense’s Supplemental Information package dated June 30, 2026 for additional detail. BASIC FFO AVAILABLE TO COMMON SHARE AND COMMON UNIT HOLDERS (“BASIC FFO”) FFO adjusted to subtract (1) preferred share dividends, (2) income or loss attributable to noncontrolling interests through ownership of preferred units in COPT Defense Properties, L.P. (the “Operating Partnership”) or interests in other consolidated entities not owned by us, (3) depreciation and amortization allocable to noncontrolling interests in other consolidated entities, (4) Basic FFO allocable to share-based compensation awards, and (5) issuance costs associated with redeemed preferred shares. With these adjustments, Basic FFO represents FFO available to common shareholders and holders of common units in the Operating Partnership (“common units”). Common units are substantially similar to our common shares of beneficial interest (“common shares”) and are exchangeable into common shares, subject to certain conditions. BRAC Base Realignment and Closure Commission of the United States Congress, the most recent of which Congress established in 2005 to ensure the integrity of the base closure and realignment process. The Commission provided an objective, non-partisan, and independent review and analysis of the list of military installation recommendations issued by the Department of Defense (“DOD”) on May 13, 2005. The Commission's mission was to assess whether the DOD recommendations substantially deviated from the Congressional criteria used to evaluate each military base. While giving priority to the criteria of military value, the Commission took into account the human impact of the base closures and considered the possible economic, environmental, and other effects on the surrounding communities.

Definitions + Glossary (continued) 30 CASH NET OPERATING INCOME (“CASH NOI”) NOI from real estate operations adjusted: to eliminate the effects of straight-line rental adjustments, amortization of tenant incentives, amortization of intangibles and other assets included in FFO and NOI, lease termination fees from tenants to terminate their lease obligations prior to the end of the agreed upon lease terms, and rental revenue recognized under GAAP resulting from landlord assets and lease incentives funded by tenants; and prospectively effective 4/1/26, for our investments in sales-type leases, to reflect scheduled lease payments, resulting in adjustments to include lease receivable principal amortization and exclude accretion of unguaranteed residual assets (this change was made prospectively effective 4/1/26 since these adjustments were not material until our acquisition of an investment in a sales-type lease on 4/23/26). Cash NOI also includes adjustments to NOI from real estate operations for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. Under GAAP, rental revenue is recognized evenly over the term of tenant leases (through straight-line rental adjustments and amortization of tenant incentives), which, given the long term nature of our leases, does not align with the economics of when tenant payments are due to us under the arrangements. Also under GAAP, when a property is acquired, we allocate the acquisition to certain intangible components, which are then amortized into NOI over their estimated lives, even though the resulting revenue adjustments are not reflective of our lease economics. In addition, revenue from lease termination fees and tenant-funded landlord improvements, absent an adjustment from us, would result in large one-time lump sum amounts in Cash NOI that we do not believe are reflective of a property’s long-term value. CASH RENT Monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (average for first 12 months of term for new or renewed leases or as of lease expiration for expiring leases. DEBT/TOTAL MARKET CAPITALIZATION Gross debt, divided by our total market capitalization. DEFENSE/IT PORTFOLIO Properties in locations proximate to, or sometimes containing, key U.S. Government defense installations and missions. DEVELOPMENT LEASING PIPELINE Formerly called the Shadow Development Pipeline, this internally maintained schedule tracks potential future development leasing transactions for which the Company is competing and believes it has a 50% or greater chance of winning within the next 24 months. DEVELOPMENT PROFIT OR YIELD Cash NOI divided by the estimated total investment, before the impact of cumulative real estate impairment losses. DILUTED ADJUSTED FUNDS FROM OPERATIONS AVAILABLE TO COMMON SHARE AND COMMON UNIT HOLDERS ("DILUTED AFFO") Diluted FFO, as adjusted for comparability, adjusted for the following: (1) the elimination of the effect of (a) noncash rental revenues and property operating expenses (comprised of straight-line rental adjustments, which includes the amortization of recurring tenant incentives, and amortization of acquisition intangibles included in FFO and NOI, both of which are described under “Cash NOI” above), (b) share-based compensation, net of amounts capitalized, (c) amortization of deferred financing costs, (d) amortization of debt discounts, commissions, and premiums, and (e) amortization of settlements of debt hedges; (2) replacement capital expenditures (defined below); and (3) prospectively effective 4/1/26, for our investments in sales-type leases, to reflect scheduled lease payments, resulting in adjustments to include lease receivable principal amortization and exclude accretion of unguaranteed residual assets (this change was made prospectively effective 4/1/26 since these adjustments were not material until our acquisition of an investment in a sales-type lease on 4/23/26). Diluted AFFO also includes adjustments to Diluted FFO, as adjusted for comparability for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. DILUTED FFO AVAILABLE TO COMMON SHARE AND COMMON UNIT HOLDERS ("DILUTED FFO") Basic FFO adjusted to add back any changes in Basic FFO that would result from the assumed conversion of securities that are convertible or exchangeable into common shares. The computation of Diluted FFO (which includes discontinued operations, if any) assumes the conversion of common units but does not assume the conversion of other securities that are convertible into common shares if the conversion of those securities would increase Diluted FFO per share in a given period. DILUTED FFO AVAILABLE TO COMMON SHARE AND COMMON UNIT HOLDERS, AS ADJUSTED FOR COMPARABILITY ("DILUTED FFO, AS ADJUSTED FOR COMPARABILITY") Diluted FFO or FFO adjusted to exclude: operating property acquisition costs (for acquisitions classified as business combinations); gain or loss on early extinguishment of debt; demolition costs on redevelopment and nonrecurring improvements; FFO associated with properties that secured non- recourse debt on which we defaulted and, subsequently, extinguished via conveyance of such properties (including property NOI, interest expense, and gains on debt extinguishment); loss on interest rate derivatives; and executive transition costs associated with named executive officers. Diluted FFO, as adjusted for comparability also includes adjustments to Diluted FFO for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs.

The computation of Diluted FFO per share assumes the conversion of common units but does not assume the conversion of other securities that are convertible into common shares if the conversion of those securities would increase Diluted FFO per share in a given period. DILUTED FFO PER SHARE, AS ADJUSTED FOR COMPARABILITY Diluted FFO available to common share and common unit holders, as adjusted for comparability divided by the sum of the (1) weighted average common shares outstanding during a period, (2) weighted average common units outstanding during a period, and (3) weighted average number of potential additional common shares that would have been outstanding during a period if other securities that are convertible or exchangeable into common shares were converted or exchanged. The computation of this measure assumes the conversion of common units but does not assume the conversion of other securities that are convertible into common shares if the conversion of those securities would increase the per share measure in a given period. DISA Defense Information Systems Agency. EARNINGS BEFORE INTEREST, INCOME TAXES, DEPRECIATION AND AMORTIZATION (“EBITDA”) See Adjusted EBITDA. EUL Enhanced Use Lease whereby the DOD grants a lease interest to a private developer in exchange for rent that the DOD can use to improve the related defense installation. FUNDS FROM OPERATIONS ("FFO" OR "FFO PER NAREIT") Net income or loss computed using GAAP, excluding gains on sales and impairment losses of real estate and investments in unconsolidated real estate JVs (net of associated income tax) and real estate-related depreciation and amortization. FFO also includes adjustments to net income or loss for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. We believe that we use the National Association of Real Estate Investment Trust’s (“Nareit”) definition of FFO, although others may interpret the definition differently and, accordingly, our presentation of FFO may differ from those of other REITs. GROSS DEBT Debt reported on our consolidated balance sheet adjusted to exclude net discounts, commissions, and premiums and deferred financing costs, as further adjusted to include outstanding debt of unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. GSA United States General Services Administration. IN-PLACE ADJUSTED EBITDA Adjusted EBITDA, as further adjusted for: (1) certain events occurring in a three month period to reflect Adjusted EBITDA as if the events occurred at the beginning of such period, including; (a) properties acquired, placed in service or expanded upon subsequent to the commencement of a period made in order to reflect a full period of ownership/operations; (b) properties removed from service or in which we disposed of interests; (c) significant mid-period occupancy changes associated with properties recently placed in service or acquired as if such occupancy changes occurred at the beginning of such period; and (2) adjustments to deferred rental revenue associated with changes in our assessment of collectability. The measure also includes adjustments for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs. We believe that the pro forma adjustments described above are consistent with the requirements for preparation of amounts presented on a pro forma basis in accordance with Article 11 of Regulation S-X. INTEREST DURATION The length of time for which an interest rate on debt is fixed. INVESTMENT SPACE LEASED Vacant space leased within two years of the shell completion date for development properties or acquisition date for operating property acquisitions. NGA National Geospatial Intelligence Agency. NET CONSTRUCTION CONTRACT AND OTHER SERVICE REVENUES Net operating income from real estate services such as property management, development and construction services primarily for the Company's properties but also for third parties. Construction contract and other service revenues and expenses consist primarily of subcontracted costs that are reimbursed to the Company by the customer along with a management fee. The operating margins from these activities are small relative to the revenue. NET DEBT Gross debt (total outstanding debt reported per our balance sheet as adjusted to exclude net discounts, commissions, and premiums and deferred financing costs), as adjusted to subtract cash and cash equivalents as of the end of the period. The measure also includes adjustments to gross debt for the effects of the items noted above pertaining to unconsolidated real estate JVs that were allocable to our ownership interest in the JVs.

The adjustments remove Adjusted EBITDA from real estate operations associated with the disposed interests in properties and adjust our net debt measures for resulting proceeds available for debt pay downs to reflect these measures and ratios as if such events occurring subsequent to a three month reporting period occurred at the beginning of such reporting period. We believe that these adjustments are consistent with the requirements for preparation of amounts presented on a pro forma basis in accordance with Article 11 of Regulation S-X. REDEVELOPMENT Properties previously in operations on which activities to substantially renovate such properties were underway or approved. REPLACEMENT CAPITAL EXPENDITURES Tenant improvements and incentives, building improvements, and leasing costs incurred during the period for operating properties that are not (1) items contemplated prior to the acquisition of a property, (2) improvements associated with the expansion of a building or its improvements, (3) renovations to a building which change the underlying classification of the building (for example, from industrial to office or Class C office to Class B office), (4) capital improvements that represent the addition of something new to the property rather than the replacement of something (for example, the addition of a new heating and air conditioning unit that is not replacing one that was previously there), or (5) replacements of significant components of a building after the building has reached the end of its original useful life. Replacement capital expenditures excludes expenditures of operating properties included in disposition plans during the period that were already sold or are held for future disposition. For cash tenant incentives not due to the tenant for a period exceeding three months past the date on which such incentives were incurred, we recognize such incentives as replacement capital expenditures in the periods such incentives are due to the tenant. Replacement capital expenditures, which is included in the computation of Diluted AFFO, is intended to represent non-transformative capital expenditures of existing properties held for long- term investment. SAME PROPERTY Operating properties stably owned and 100% operational since at least the beginning of the prior year. SAME PROPERTY NOI AND SAME PROPERTY CASH NOI NOI, or Cash NOI, from real estate operations of Same Property groupings. SCIF Sensitive (or Secure) Compartmented Information Facility, or “SCIF,” in U.S. military, security, and intelligence parlance is an enclosed area within a building that is used to process classified information within formal access controlled systems (as established by the Director of National Intelligence). STABILIZATION Properties that are at least 90% occupied. STRAIGHT-LINE RENT Annual minimum base rents, net of abatements and lease incentives and excluding rent associated with tenant funded landlord assets, on a straight-line basis over the term of the lease, and estimated annual expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). TOTAL MARKET CAPITALIZATION The sum of: (1) consolidated outstanding debt, excluding net discounts, commissions, and premiums and deferred financing costs; (2) the product of the closing price of our common shares on the NYSE and the sum of (a) common shares outstanding and (b) common units outstanding; and (3) the liquidation value of preferred shares and preferred units in our operating partnership. DEVELOPMENT PROPERTIES Properties under, or contractually committed for, development. VACANT SPACE LEASED Leasing of vacated second-generation space and vacant space leased in development properties and operating property acquisitions after two years from such properties’ shell completion or acquisition date.
