Summary Description

THE COMPANY

COPT Defense Properties (the “Company” or “CDP”), an S&P MidCap 400 Company, is a self-managed real estate investment trust (“REIT”) focused on owning, operating and developing properties in locations proximate to, or sometimes containing, key U.S. Government (“USG”) defense installations and missions (which we refer to herein as our Defense/IT Portfolio). Our tenants include the USG and their defense contractors, who are primarily engaged in priority national security activities, and who generally require mission-critical and high security property enhancements. In September 2023, we changed our name from Corporate Office Properties Trust to COPT Defense Properties to better describe our investment strategy’s focus on locations serving our country’s priority defense activities. The ticker symbol under which our common shares are publicly traded on the New York Stock Exchange changed from “OFC” to “CDP”. As of September 30, 2023, our Defense/IT Portfolio of 188 properties, including 24 owned through unconsolidated joint ventures, encompassed 21.3 million square feet and was 97.0% leased.

Definitions

Non-GAAP Measures

We believe that the measures defined below that are not determined in accordance with generally accepted accounting principles (“GAAP”) are helpful to investors in measuring our performance and comparing it to that of other real estate investment trusts (“REITs”).  Since these measures exclude certain items includable in their respective most comparable GAAP measures, reliance on the measures has limitations; management compensates for these limitations by using the measures simply as supplemental measures that are weighed in balance with other GAAP and non-GAAP measures.  These measures should not be used as an alternative to the respective most comparable GAAP measures when evaluating our financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt service.

Adjusted book

Defined as 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. We use adjusted book for purposes of calculating our net debt to adjusted book, which we believe is a useful supplemental measure for investors to use in further understanding the relationship of our outstanding debt to our assets available to service such debt. We believe that total assets is the most directly comparable GAAP measure to this non-GAAP measure.

Adjusted earnings before interest, income taxes, depreciation and amortization (“Adjusted EBITDA”)

Adjusted EBITDA is 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. While EBITDA (earnings before interest, taxes, depreciation and amortization) is a universally-defined supplemental measure, Adjusted EBITDA incorporates additional adjustments for gains and losses from investing and financing activities and certain other items that we believe represent costs that are not closely correlated to (or associated with) our operating performance and are not relevant to an investor’s evaluation of our ability to repay debt. We believe that adjusted EBITDA is a

useful supplemental measure for assessing our un-levered performance and ability to repay outstanding debt from operations.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Adjusted EBITDA debt service coverage ratio

This measure divides Adjusted EBITDA by the sum of interest expense (excluding amortization of deferred financing costs and amortization of debt discounts and premiums, net of amounts capitalized, and gains or losses on interest rate derivatives) and scheduled principal amortization on mortgage loans.

Amortization of acquisition intangibles included in NOI

Represents the amortization of intangible asset and liability categories that is included in net operating income, including amortization of above- or below-market leases and above- or below-market cost arrangements.

Basic FFO available to common share and common unit holders (“Basic FFO”)

This measure is 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.  We believe that Basic FFO is useful to investors due to the close correlation of common units to common shares.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Cash net operating income (“Cash NOI”)

Defined as 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.  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.  We believe that Cash NOI is a useful supplemental measure of operating performance for a REIT’s operating real estate because it makes adjustments to NOI for the above stated items to be more reflective of the economics of when tenant payments are due to us under our leases and the value of our properties.  As is the case with NOI, the measure is useful in our opinion in evaluating and comparing the performance of reportable segments, Same Property groupings and individual properties.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

CDP’s share of NOI from unconsolidated real estate JVs

Represents the net of revenues and property operating expenses of real estate operations owned through unconsolidated JVs that are allocable to CDP’s ownership interest. This measure is included in the computation of NOI, our segment performance measure, as discussed below.

Diluted adjusted funds from operations available to common share and common unit holders (“Diluted AFFO”)

Defined as 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 and premiums and (e) amortization of settlements of debt hedges; and (2) replacement capital expenditures (defined below).  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. We believe that Diluted AFFO is a useful supplemental measure of operating performance for a REIT because it incorporates adjustments for: certain revenue and expenses that are not associated with cash to or from us during the period; and certain capital expenditures for operating properties incurred during the period that do require cash outlays.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Diluted FFO available to common share and common unit holders (“Diluted FFO”)

Diluted FFO is 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 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.  We believe that Diluted FFO (which includes discontinued operations) is useful to investors because it is the numerator used to compute Diluted FFO per share, discussed below.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Diluted FFO available to common share and common unit holders, as adjusted for comparability (“Diluted FFO, as adjusted for comparability”)

Defined as Diluted FFO or FFO adjusted to exclude: operating property acquisition costs; gain or loss on early extinguishment of debt; 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; executive transition costs associated with named executive officers; and, for periods prior to 10/1/22, demolition costs on redevelopment and nonrecurring improvements and executive transition costs associated with other senior management team members.  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. We believe this to be a useful supplemental measure alongside Diluted FFO as it excludes gains and losses from certain investing and financing activities and certain other items that we believe are not closely correlated to (or associated with) our operating performance. We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Diluted FFO per share

Diluted FFO per share is (1) Diluted FFO divided by (2) the sum of the (a) weighted average common shares outstanding during a period, (b) weighted average common units outstanding during a period and (c) 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 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.  We believe that Diluted FFO per share is useful to investors because it provides investors with a further context for evaluating our FFO results in the same manner that investors use earnings per share (“EPS”) in evaluating net income or loss available to common shareholders.  We believe that diluted EPS is the most directly comparable GAAP measure to this non-GAAP measure.

Diluted FFO per share, as adjusted for comparability

Defined as (1) Diluted FFO available to common share and common unit holders, as adjusted for comparability divided by (2) the sum of the (a) weighted average common shares outstanding during a period, (b) weighted average common units outstanding during a period and (c) 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.  We believe this to be a useful supplemental measure alongside Diluted FFO per share as it excludes gains and losses from investing and financing activities and certain other items that we

believe are not closely correlated to (or associated with) our operating performance. We believe that diluted EPS is the most directly comparable GAAP measure to this non-GAAP measure.

Earnings before interest, income taxes, depreciation and amortization for real estate (“EBITDAre”)

Defined as net income or loss adjusted for the effects of interest expense, depreciation and amortization, gains on sales and impairment losses of real estate and investments in unconsolidated real estate JVs, and income taxes. EBITDAre 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. While EBITDA (earnings before interest, taxes, depreciation and amortization) is a universally-defined supplemental measure, EBITDAre incorporates additional adjustments for gains and losses from investing activities related to our investments in operating properties. We believe that EBITDAre is a useful supplemental measure for assessing our un-levered performance. We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Funds from operations (“FFO” or “FFO per Nareit”)

Defined as 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.  We believe that FFO is useful to management and investors as a supplemental measure of operating performance because, by excluding gains on sales and impairment losses of real estate (net of associated income tax) and real estate-related depreciation and amortization, FFO can help one compare our operating performance between periods.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Gross debt

Defined as debt reported on our consolidated balance sheet adjusted to exclude net discounts 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. We believe that this measure is useful to investors as it represents our total outstanding debt, including our share of unconsolidated joint venture debt. We believe that debt reported on our consolidated balance sheet is the most directly comparable GAAP measure to this non-GAAP measure.

In-place adjusted EBITDA

Defined as 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 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. We believe that in-place adjusted EBITDA is a useful supplemental measure of performance for assessing our un-levered performance and ability to repay outstanding debt from operations, as further adjusted for changes in operating properties subsequent to the commencement of a quarter and for the other items noted above that we believe are not closely correlated with our operating performance and are not relevant to an investor’s evaluation of our ability to repay debt.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

Net debt

Defined as Gross debt (total outstanding debt reported per our balance sheet as adjusted to exclude net discounts 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. We use net debt for purposes of calculating our net debt to adjusted book, which we believe is a useful supplemental measure for investors to use in further understanding the relationship of our outstanding debt to our assets available to service such debt. We believe that debt reported on our consolidated balance sheet is the most directly comparable GAAP measure to this non-GAAP measure.

Net debt adjusted for fully-leased development

Defined as Net debt less costs incurred on properties under development that were 100% leased. We believe that this supplemental measure is useful in providing investors the impact to our debt of fully leased properties under development that are not yet contributing to our adjusted EBITDA. We believe that debt reported on our consolidated balance sheet is the most directly comparable GAAP measure to this non-GAAP measure.

Net debt to Adjusted book

Defined as Net debt divided by Adjusted book (defined above).

41

COPT Defense Properties

Definitions

Net debt to in-place adjusted EBITDA ratio and Net debt adjusted for fully-leased development to in-place adjusted EBITDA ratio

Defined as Net debt or Net debt adjusted for fully-leased development divided by in-place adjusted EBITDA (defined above) for the three month period that is annualized by multiplying by four.

Net operating income from real estate operations (“NOI”)

NOI, which is our segment performance measure, includes: consolidated real estate revenues from continuing and discontinued operations; consolidated property operating expenses from continuing and discontinued operations; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate JVs that are allocable to CDP’s ownership interest in the JVs. We believe that NOI is an important supplemental measure of operating performance for a REIT’s operating real estate because it provides a measure of the core real estate operations that is unaffected by depreciation, amortization, financing and general, administrative and leasing expenses; we believe this measure is particularly useful in evaluating the performance of reportable segments, Same Property groupings and individual properties.  We believe that net income or loss is the most directly comparable GAAP measure to this non-GAAP measure.

NOI fixed charge coverage ratio and Adjusted EBITDA fixed charge coverage ratio

These measures divide either NOI from real estate operations or Adjusted EBITDA by the sum of (1) interest expense (excluding amortization of deferred financing costs and amortization of debt discounts and premiums, net of amounts capitalized, and gains or losses on interest rate derivatives), (2) scheduled principal amortization on mortgage loans, (3) capitalized interest, (4) dividends on preferred shares and (5) distributions on preferred units in the Operating Partnership not owned by us.

NOI interest coverage ratio and Adjusted EBITDA interest coverage ratio

These measures divide either NOI from real estate operations or Adjusted EBITDA by interest expense (excluding amortization of deferred financing costs and amortization of debt discounts and premiums, net of amounts capitalized, gains on losses on interest rate derivatives and interest expense on debt in default to be extinguished via conveyance of properties).

Payout ratios based on: Diluted FFO; Diluted FFO, as adjusted for comparability; and Diluted AFFO

These payout ratios are defined as (1) the sum of dividends on common and deferred shares and distributions to holders of interests in the Operating Partnership to the extent they are dilutive in the respective FFO per share numerators divided by (2) the respective non-GAAP measures.

Pro forma net debt, pro forma net debt adjusted for fully-leased development, pro forma in-place adjusted EBITDA and associated ratios

These measures and the ratios in which they are used adjust for the effect of noted dispositions of interests in properties that occurred subsequent to the end of reporting periods and before our release of financial results for such periods. 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. We believe that these further adjusted versions of these measures/ratios are useful in presenting the effect of the dispositions on our un-levered performance and ability to repay outstanding debt from operations.  We believe that debt reported on our consolidated balance sheet is the most directly comparable GAAP measure to pro forma net debt and pro forma net debt adjusted for fully-leased development and that net income or loss is the most directly comparable GAAP measure to pro forma in-place adjusted EBITDA.

Replacement capital expenditures

Replacement capital expenditures are defined as 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. We believe that the excluded expenditures are more closely associated with our investing activities than the performance of our operating portfolio.

Same Property NOI from real estate operations and Same Property cash NOI

from real estate operations Defined as NOI, or Cash NOI, from real estate operations of Same Property groupings.  We believe that these are important supplemental measures of Same Property operating performance for the same reasons discussed above for NOI from real estate operations and Cash NOI from real estate operations.

Other Definitions

Acquisition Costs — Transaction costs expensed in connection with executed or anticipated acquisitions of operating properties.

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 Annualized Rental Revenue allocable to CDP’s ownership interest. We consider ARR to be a useful measure for analyzing revenue sources because, since it is point-in-time based, it does not contain increases and decreases in revenue associated with periods in which lease terms were not in effect; historical revenue under GAAP does contain such fluctuations. We find the measure particularly useful for leasing, tenant, segment and industry analysis.

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.

Cash Rent — Includes monthly contractual base rent (ignoring rent abatements and rent associated with tenant funded landlord assets) multiplied by 12, plus estimated annualized expense reimbursements (as of lease commencement for new or renewed leases or as of lease expiration for expiring leases). We believe that cash rent is a useful measure for evaluating the rental rates at the time rent payments commence for our leasing activity, including changes in such rates relative to rates that may have been previously in place.

Committed cost per square foot — Includes tenant improvement allowance (excluding tenant funded landlord assets), leasing commissions and estimated turn key costs and excludes lease incentives. We believe this is a useful measure for evaluating our costs associated with obtaining new leases.

Debt to net income ratio — Represents debt reported on our consolidated balance sheet divided by net income for the three month period that is annualized by multiplying by four. We do not present this ratio for periods with a net loss.

Defense/IT Portfolio — Represents properties in locations proximate to, or sometimes containing, key U.S. Government (“USG”) defense installations and missions.

Development Properties — Properties under, or contractually committed for, development.

Equity Market Capitalization — Defined as the sum of: (1) 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 (2) the liquidation value of preferred shares and preferred units in our operating partnership.

First Generation Space — Newly-developed or redeveloped space that has never been occupied.

Net income to interest expense ratio — Represents net income reported on our consolidated statements of operations divided by interest expense. We do not present this ratio for periods with a net loss.

Net income payout ratio — defined as (1) the sum of dividends on common and deferred shares and distributions to holders of interests in the Operating Partnership divided by (2) net income. We do not present this ratio for periods with a net loss.

Operational Space — The portion of a property in operations (excludes portion under development or redevelopment).

Redevelopment Properties — Properties previously in operations on which activities to substantially renovate such properties were underway or approved.

Same Property — Operating properties stably owned and 100% operational since at least 1/1/22.

Second Generation Space — Space leased that has been previously occupied.

Straight-line Rent — Includes 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). We believe that straight-line rent is a useful measures for evaluating the rental rates over the related lease terms for our leasing activity, including changes in such rates relative to rates that may have been previously in place.

Total Market Capitalization — Defined as the sum of: (1) consolidated outstanding debt, excluding discounts, 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.

Total Portfolio — Operating properties, including ones owned through unconsolidated real estate JVs.

Vacancy leasing activity ratio — Square footage associated with prospective tenants for vacant square feet in service divided by total vacant square feet in service.

Vacant space leased — Includes acquired first generation space, vacated second generation space and leases executed on developed and redeveloped space previously placed in service.

COLUMBIA, MD (BUSINESS WIRE) October 26, 2023 - COPT Defense Properties (“COPT Defense” or the “Company”) (NYSE: CDP) announced results for the third quarter ended September 30, 2023.

Management Comments

Stephen E. Budorick, COPT Defense’s President & Chief Executive Officer, commented, “Our Defense/IT investment strategy, which has concentrated our portfolio near priority U.S. defense installations, continues to produce strong results. Our Defense/IT Portfolio is 97% leased, which is the highest leased rate since we started

i

reporting the segment in 2015, supported by growth in defense spending, resulting in continued tenant demand from both our U.S. Government and Defense Contractor tenants.

Our third quarter results were solid, with FFO per share at the midpoint of our guidance range, which led us to narrow the full-year guidance range. We continue to outperform in terms of same property cash NOI growth, which increased 4.5% for 3Q23 over 3Q22, and 6.2% in 2023 YTD over 2022 YTD, which led us to increase our full-year change in same property cash NOI guidance by another 100 basis points. We are highly confident that we will achieve our leasing goals, as we have executed 84% of our vacancy leasing goal and 70% of our development leasing goal, while tenant retention YTD is squarely within our full-year guidance range.

From a balance sheet perspective, our Finance and Capital Markets team once again proved our ability to source low-cost capital to fund our accretive and highly leased development pipeline, as evidenced by our September issuance of $345 million of exchangeable notes due 2028 at 5.25%, which was roughly 200 basis points below where we could have priced 5-year unsecured debt. With this capital raise, and our ability to fund the equity investment in our projects with cash flow from operations after our dividend payments, we forecast we can now fund our anticipated development spend through late 2026. Our investment grade balance sheet is well positioned to navigate the challenging capital markets environment, as we have no variable rate debt exposure and have no significant debt maturity until 2026.

We remain confident in our strategy of allocating capital to investments in our Defense/IT Portfolio that will support continued growth in FFO per share and shareholder value.”

Financial Highlights

3rd Quarter Financial Results:

•Diluted earnings per share (“EPS”) was ($1.94) for the quarter ended September 30, 2023, which included a $252.8 million impairment charge for six operating properties in the Other segment and a parcel of land, located in Baltimore, Maryland, Northern Virginia and Washington, D.C., resulting from our quarterly portfolio review.

In September 2023, the Company changed its name from Corporate Office Properties Trust to COPT Defense Properties to better describe its investment strategy’s focus on locations serving U.S. priority defense activities. The ticker symbol under which the Company’s common shares are publicly traded on the New York Stock Exchange changed from “OFC” to “CDP.” As of September 30, 2023, the Company’s Defense/IT Portfolio of 188 properties, including 24 owned through unconsolidated joint ventures, encompassed 21.3 million square feet and was 97.0% leased.
