6 terms

Funds from Operations financial

"COPT Defense Properties Funds from Operations (in thousands)"

Funds from operations (FFO) measures the cash a real estate-focused company generates from its core property operations by adjusting net income to add back non-cash expenses like building depreciation and removing one-time gains or losses from property sales. Investors use FFO like a household’s monthly take-home pay—it's a clearer view of ongoing cash available to pay dividends, maintain properties and fund growth than raw accounting profit.

Adjusted Funds from Operations financial

"COPT Defense Properties Adjusted Funds from Operations (in thousands)"

Adjusted funds from operations is a financial measure that shows how much cash a real estate company generates from its property operations, excluding certain non-recurring items and accounting adjustments. It helps investors understand the company’s true cash flow ability to pay dividends or fund growth. This figure offers a clearer picture of ongoing financial performance by removing irregular or one-time factors that can distort regular income.

EBITDAre financial

"COPT Defense Properties EBITDAre + Adjusted EBITDA (in thousands)"

EBITDARE is a financial measure that shows a company's earnings before accounting for interest, taxes, depreciation, amortization, and restructuring costs. It helps investors understand how well a business is performing by focusing on its core operations, ignoring one-time or non-operational expenses. Think of it as checking a company's true earning power, similar to assessing a car’s performance by its engine without considering external factors like fuel costs or repairs.

Same Property cash NOI financial

"Same Property cash NOI from real estate operations (“cash NOI”)"

Measure of net operating income generated by a fixed group of properties that were owned and operating in both the current and prior reporting periods, calculated on a cash basis by excluding non-cash accounting items and the effects of acquisitions or dispositions. It matters to investors because it isolates the underlying, recurring cash profitability of the same assets over time, much like tracking sales and expenses at the same set of stores to see true operational trends.

Annualized Rental Revenue financial

"Annualized Rental Revenue of Expiring Leases per Occupied Sq. Foot"

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

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”)

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

Adjusted EBITDA divided by the sum of interest expense (excluding amortization of deferred financing costs and amortization of debt discounts, commissions, 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

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”)

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”)

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. 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.


COPT Defense’s share of NOI from unconsolidated real estate JVs

Net of revenues and property operating expenses of real estate operations owned through unconsolidated JVs that are allocable to COPT Defense’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”)

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. 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”)

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, if any) 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”)

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. 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 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 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

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. 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”)

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”)

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

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. 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

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. 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

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. 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 investment properties

Net debt less costs incurred on properties under development and on operating property acquisitions that were 100% leased. We believe that this supplemental measure is useful in providing investors the impact to our debt of these fully leased properties 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

Net debt divided by Adjusted book (defined above).


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

Net debt or Net debt adjusted for fully-leased investment properties 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”)

Consolidated real estate revenues; consolidated property operating expenses; and the net of revenues and property operating expenses of real estate operations owned through unconsolidated real estate JVs that are allocable to COPT Defense’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

NOI from real estate operations or Adjusted EBITDA divided by the sum of (1) interest expense (excluding amortization of deferred financing costs and amortization of debt discounts, commissions, 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

NOI from real estate operations or Adjusted EBITDA divided by interest expense (excluding amortization of deferred financing costs and amortization of debt discounts, commissions, 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

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 the respective non-GAAP measures.


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. 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

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 ARR allocable to COPT Defense’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. In instances in which we report ARR per occupied square foot, the measure excludes revenue from leases not associated with our buildings.

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 — 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). 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 — 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.

Compound Annual Growth Rate — The compound annual growth rate for renewed space between the first year cash rent of the expired lease and the first year cash rent of the renewal lease.

Debt to Net Income Ratio — 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 — 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 — 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.

Investment Space Leased — Vacant space leased within two years of the shell completion date for development properties or acquisition date for operating property acquisitions.

Net Income to Interest Expense Ratio — 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 — The sum of (1) 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 1/1/25.

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

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 — 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.

COLUMBIA, MD (BUSINESS WIRE) July 27, 2026 - COPT Defense Properties (“COPT Defense” or the “Company”) (NYSE: CDP) announced results for the second quarter ended June 30, 2026.

Management Comments

Stephen E. Budorick, COPT Defense’s President & Chief Executive Officer, commented, “Our performance during the first half of the year exceeded our plan and expectations in every respect. Our financial results, occupancy, leasing activity, and capital commitments to new investments continue to illustrate the benefits and opportunities from the strong demand for our portfolio, as FFO per share exceeded the midpoint of our guidance by $0.02 in the second quarter.

We increased the midpoint of 2026 FFO per share guidance by $0.02 to $2.78, which is $0.03 above our initial guidance. This is even more impressive considering this overcomes roughly $0.035 of incremental dilution from our Exchangeable Notes relative to our initial guidance, resulting from our 37% share price increase year-to-date. We also increased the midpoint of 2026 guidance for same property cash NOI growth by 100 basis points to 4.0%, the change in cash rents on renewals by 100 basis points to 3.0%, and capital commitment to new investments by $45 million to $335 million. Additionally, we raised our target for vacancy leasing by nearly 20% from 400,000 square feet to 475,000 square feet, based on the 231,000 square feet signed in the first half of the year, and our strong pipeline of deals in advanced negotiations.

We expect bipartisan support for growth in defense spending will continue, as the FY 2027 Budget Request calls for a 28% increase in the base budget to nearly $1.1 trillion, which excludes any additional funding from reconciliation. The FY 2027 Budget Requests also calls for meaningful increases in funding for the priority missions our portfolio supports, which includes intelligence, cybersecurity, and missile defense, thereby creating a favorable environment for continued demand in our portfolio."
