Historically, future market rental and occupancy rates have tended to be the most variable assumption in our impairment analyses of properties to be held and used; while changes in these assumptions can significantly affect our estimates of property undiscounted future cash flows in our recoverability analyses, such changes historically have not usually resulted in impairment losses since the resulting recoverability analyses still have tended to exceed the carrying value of the property asset groups.

Most of these lease renewals were for our Defense/IT Portfolio, which had a retention rate of 88.6%, while our Other segment had a retention rate of 49.4%.
The renewed leases had a weighted average lease term of approximately 4.8 years, with average escalations per year of 2.6%, and the per annum average committed costs associated with completing the leasing was approximately $3.16 per square foot. In 2023, we also completed leasing on 452,000 square feet of vacant space, predominantly for our Defense/IT Portfolio.

In 2025 and beyond, we expect to continue to actively develop additional properties and also could opportunistically acquire operating properties. We expect to fund these activities using, in part, available cash flow from operations and any excess available cash and cash equivalents, with the balance funded, at least initially, using borrowings under our Revolving Credit Facility.
We consider annualized rental revenue 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 generally accepted accounting principles in the United States of America (“GAAP”) does contain such fluctuations.
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.

Please refer to the section below entitled “Occupancy and Leasing” for additional related disclosure. 24 As of December 31, 2024, we ended the year with: > no significant debt maturing until 2026; > $525.0 million in available borrowing capacity under our Revolving Credit Facility; > no variable-rate debt exposure, including the effect of interest rate swaps; > only 2.9% of our outstanding debt encumbered by properties; and > the ability to fund the equity portion of our investing activities with cash flow from operations for the foreseeable future.
However, we did not initiate plans for sales of these properties in 2023 due in part to the anticipated effects of increased interest rates and debt availability on potential buyers.
While we intend to sell them when market conditions and opportunities position us to optimize our return on investment, we did not initiate plans for sales in 2024 due in large part to the effects of increased interest rates and debt availability on potential buyers.
As of December 31, 2023 we had scheduled lease expirations in 2024 for 352,000 square feet, or 32%, of this sub-segment’s occupied square feet, most of which we expect to renew; > Redstone Arsenal: Increase was due primarily to the commencement of occupancy from vacant space leasing in a number of properties in this sub-segment; and > Other: Decreased due to vacated space resulting from its 25.3% tenant retention rate and minimal vacant space leasing.
As of December 31, 2024 we had scheduled lease expirations in 2025 for 166,000 square feet, or 15.8%, of this sub-segment’s occupied square feet, most of which we expect to renew; > Redstone Arsenal: Decreased due primarily to vacant space placed into service in a newly-developed property to accommodate future anticipated demand in a highly-leased business park; and > Other: Decreased due to vacated space resulting from a 49.4% tenant retention rate, the effect of which outweighed lease commencements on vacant space leased.
Net cash flow used in investing activities increased $86.2 million from 2022 to 2023 due in large part to lower proceeds from properties sold in 2023, which included our sale of a 90% interest in three data center shells, relative to 2022, which included sales of our wholesale data center and a 90% interest in two data center shells.
Net cash flow used in investing activities increased $121.4 million from 2023 to 2024 due primarily to proceeds from properties sold in 2023 (which included our sale of a 90% interest in three data center shells), which was partially offset by decreased cash paid for properties in development or held for future development.
As of December 31, 2023, we were compliant with these covenants. 40 Recent Accounting Pronouncements See Note 2 to our consolidated financial statements for information regarding recent accounting pronouncements.

As of December 31, 2023, we had scheduled lease expirations for 2.6 million square feet in 2024, representing 11.5% of our total occupied square feet and 12.8% of our total annualized rental revenue, including: > 2.4 million square feet in our Defense/IT Portfolio segment, a high proportion of which we expect to renew; and > 161,000 square feet in our Other segment, most of which we do not expect to renew.
As of December 31, 2024, we had scheduled lease expirations for 3.0 million square feet in 2025, representing 13.0% of our total occupied square feet and 19.2% of our total ARR, including: > 2.8 million square feet in our Defense/IT Portfolio segment, a high proportion of which we expect to renew due to the unique retention advantages associated with our Defense/IT strategy discussed above; and > 144,000 square feet in our Other segment, the renewal of which we believe was highly uncertain.
We find the measure particularly useful for leasing, tenant, segment and industry analysis. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period; we include the effect of early renewals in this measure.
In instances in which we report ARR per occupied square foot, the measure excludes revenue from leases not associated with our buildings. Tenant retention rate is a measure we use that represents the percentage of square feet renewed in a period relative to the total square feet scheduled to expire in that period, including the effect of early renewals.
This pool of properties changed from the pool used for purposes of comparing 2022 and 2021 in our 2022 Annual Report on Form 10-K due to the: addition of seven properties placed in service and 100% operational on or before January 1, 2022 and two properties owned through a UJV that was formed in 2021; and removal of three properties in which we sold a 90% interest in 2023. 34 Regarding the changes in NOI from real estate operations reported above: > the increase for our Same Property pool was due in large part to additional revenue in 2023 resulting from higher occupancy and the commencement of tenant expense reimbursements on certain recently commenced leases; > developed and redeveloped properties placed in service reflects the effect of 13 properties placed in service in 2023 and 2022; and > dispositions, net of retained interest in newly-formed UJVs reflects the effect of our sale of 90% of our interests in three data center shells in 2023 and two in 2022, as well as the sale of our wholesale data center on January 25, 2022.
This pool of properties changed from the pool used for purposes of comparing 2023 and 2022 in our 2023 Annual Report on Form 10-K due to the addition of seven properties placed in service and 100% operational on or before January 1, 2023 and two properties owned through a UJV that was formed in 2022.
Cash Flows Net cash flow from operating activities increased $10.4 million, or 3.9%, from 2022 to 2023, which included the effects of increased cash flow from real estate operations resulting from the growth of our operating portfolio, offset in part by higher payments for lease incentives and sales-type lease costs and lower interest income received on investing receivables from the City of Huntsville in 2023.
Cash Flows Net cash flow from operating activities increased $54.7 million, or 19.8%, from 2023 to 2024 due primarily to the effects of the growth of our operating portfolio, along with an increase in interest income on investing receivables received in 2024, and partially offset by higher cash paid for interest expense on our 5.25% Notes issued in September 2023.
Interest Expense The table below sets forth components of our interest expense: For the Years Ended December 31, 2023 2022 Variance (in thousands) Interest on unsecured senior notes $ 53,546 $ 47,496 $ 6,050 Interest on mortgage and other secured debt 5,072 4,632 440 Interest on unsecured term debt 8,139 3,503 4,636 Interest on Revolving Credit Facility 8,341 6,800 1,541 Interest expense (offsets) additions from interest rate swaps (3,900) 946 (4,846) Amortization of deferred financing costs 2,580 2,297 283 Other interest 1,843 2,209 (366) Capitalized interest (4,479) (6,709) 2,230 Interest expense $ 71,142 $ 61,174 $ 9,968 Regarding the changes in interest expense components reported above: the increase for unsecured senior notes was attributable to the 5.25% Notes issued in September 2023; and the increases for the unsecured term debt and Revolving Credit Facility were attributable to higher variable interest rates, the effect of which was mostly offset by interest rate swaps in place during the respective periods.
Interest Expense The table below sets forth components of our interest expense: For the Years Ended December 31, 2024 2023 Variance (in thousands) Interest on unsecured senior notes $ 67,301 $ 53,546 $ 13,755 Interest on mortgage and other secured debt 4,245 5,072 (827) Interest on unsecured term debt 8,338 8,139 199 Interest on Revolving Credit Facility 5,009 8,341 (3,332) Interest expense offsets from interest rate swaps (4,330) (3,900) (430) Amortization of deferred financing costs 2,708 2,580 128 Other interest 1,752 1,843 (91) Capitalized interest (2,872) (4,479) 1,607 Interest expense $ 82,151 $ 71,142 $ 11,009 Interest expense increased due primarily to the issuance in September 2023 of our 5.25% Exchangeable Senior Notes due 2028 (“5.25% Notes”). 33 Our average outstanding debt was $2.4 billion in 2024 and $2.3 billion in 2023, and our weighted average effective interest rate on debt was approximately 3.2% in 2024 and 3.0% in 2023.
Our properties under development included three data center shells and two properties in Redstone Arsenal. We believe that our Defense/IT Portfolio has strongly benefited from continued: > defense budget appropriation increases, with bipartisan support, and without extended delays in appropriations in recent years.
Our Defense/IT Portfolio also benefited from continued defense budget appropriation increases, with bipartisan support in recent years.
Net cash flow used in financing activities in 2022 was $183.2 million, and included primarily the following: > dividends to common shareholders of $123.6 million; and > net repayments of debt borrowings during the period of $43.3 million, which included the net effect of: repayments of our Revolving Credit Facility and term loan facility primarily using property sale proceeds; proceeds from our Revolving Credit Facility used primarily to fund property development; and the refinancing of our existing Revolving Credit Facility and term loan facility using proceeds from new facilities.
Net cash flow used in financing activities in 2024 was $169.7 million, and included primarily the following: > net repayments of debt borrowings during the period of $30.0 million; and > dividends to common shareholders of $131.8 million.
Our strengthened operating property occupancy in 2023 included increases in: > total portfolio year-end occupancy rate from 92.7% to 94.2%, with a year-end leased rate of 95.3%; > Defense/IT Portfolio year-end occupancy rate from 94.1% to 96.2%, with a year-end leased rate of 97.2%; 24 > Same Property year-end occupancy rate from 92.0% to 93.4%, with a year-end leased rate of 94.7% for our Same Properties in total and 96.8% for the Defense/IT Portfolio component; and > average Same Property occupancy from 91.6% to 92.7%, and from 92.9% to 94.7% for the Defense/IT Portfolio component.
Conversely, the 2024 year end occupancy rate of our Same Property pool (which excludes the effect of properties acquired and placed in service) increased (relative to 2023) from 93.8% to 94.1% for our total portfolio and from 96.0% to 96.4% for the Defense/IT Portfolio component due to lease commencements on vacant space leasing and strong tenant retention (86.0% for the total portfolio and 88.6% for the Defense/IT Portfolio).

We refer to the measures “annualized rental revenue” and “tenant retention rate” in various sections of the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of this Annual Report on Form 10-K. Annualized rental revenue is a measure that we use to evaluate the source of our rental revenue as of a point in time.
ARR is a measure that we use to evaluate the source of our rental revenue as of a point in time.
In addition, we owned eight office properties in our Other segment as of December 31, 2023 that we do not consider strategic holdings since they do not align with our Defense/IT strategy. We intend to sell these properties when we believe that market conditions and opportunities position us to optimize our return on investment.
We do not consider these properties to be strategic holdings since they do not align with our Defense/IT strategy.
Overview In 2023, we: > experienced continued strong demand across our Defense/IT Portfolio segments that drove: > strengthened occupancy of our operating properties, with year-end occupancy and leased rates at near-record levels; and > near-record tenant retention rates, at increased rent levels; > continued growth through substantially pre-leased development, with space placed in service during the year that was virtually full and a pipeline of substantially pre-leased properties under development at year end; > raised capital from a sale of interests in data center shell properties, using the proceeds to create borrowing capacity to fund future development activities; > opportunistically issued debt through a private placement to pre-fund the expected borrowings needed to fund our forecasted development activities for most of the next three years; and > ended the year with no significant debt maturing until 2026, most of our Revolving Credit Facility’s borrowing capacity available and significant cash balances on hand.
Overview In 2024, we: > achieved year end occupancy of 93.6% for our total portfolio and 95.6% for our Defense/IT Portfolio; > completed strong leasing in our operating portfolio, with our highest tenant retention rate in over 20 years and vacant space leased during the year exceeding space vacated upon lease expirations; > placed into service space in three properties that were substantially leased and commenced development of two additional properties; > acquired operating properties for the first time in nine years to add supply to highly-leased business parks; > replenished our supply of land to support future data center shell development; and > ended the year with no significant debt maturing until 2026 and most of our Revolving Credit Facility’s borrowing capacity available.
