2. Summary of Significant Accounting Policies

Interim Financial Information

The accompanying interim financial statements have been presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions to Form 10-Q and Regulation S-X for interim financial information. Accordingly, these statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements include all adjustments, consisting of normal recurring items, necessary for their fair statement in conformity with GAAP. Interim results are not necessarily indicative of results for a full year. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Basis of Presentation

The Company’s consolidated financial statements include the accounts of the Company, the Operating Partnership, and their consolidated subsidiaries. Interests in the Operating Partnership not owned by the Company are referred to as “Noncontrolling Common Units.” These Noncontrolling Common Units are held by other limited partners in the form of common units (“Other Common Units”) and long term incentive plan units (“LTIP units”) issued pursuant to the STAG Industrial, Inc. 2011 Equity Incentive Plan, as amended and restated (the “2011 Plan”). All majority-owned subsidiaries and joint ventures over which the Company has a controlling financial interest are included in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in the consolidation of entities. The financial statements of the Company are presented on a consolidated basis for all periods presented.

Recent Accounting Pronouncements Not Yet Adopted

In November 2024, the Financial Accounting Standards Board issued Accounting Standards Update 2024-03, “Disaggregation of Income Statement Expenses” (“ASU 2024-03”). ASU 2024-03 requires enhanced disclosures regarding income statement expenses, including disaggregation of significant categories, such as depreciation and amortization of real estate assets, property operating expenses, and employee compensation, within relevant expense captions presented in the income statement. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026. The Company is currently evaluating ASU 2024-03 to determine the impact on its financial statement disclosures.

The applicable fair value guidance establishes a three tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The fair value of the Company’s debt is based on Level 3 inputs.

5. Derivative Financial Instruments

Risk Management Objective of Using Derivatives

The Company’s use of derivative instruments is limited to the utilization of interest rate swaps to manage interest rate risk exposure on existing and future liabilities and not for speculative purposes. The principal objective of such arrangements is to minimize the risks and related costs associated with the Company’s operating and financial structure.

As of March 31, 2026, the Company had 18 interest rate swaps, all of which are used to hedge the variable cash flows associated with unsecured loans. All of the Company’s interest rate swaps convert the related loans’ Term SOFR or Daily SOFR components, as applicable, to effectively fixed interest rates, and the Company has concluded that each of the hedging relationships are highly effective.

Table of Contents

The following table summarizes the fair value of the interest rate swaps as of March 31, 2026 and December 31, 2025.


	March 31, 2026				December 31, 2025
Balance Sheet Line Item (in thousands)	Effective Notional Amount		Fair Value		Effective Notional Amount		Fair Value
Interest rate swaps-gross asset	$	825,000	$	15,578	$	825,000	$	13,529
Interest rate swaps-gross liability	$	200,000	$	(460)	$	200,000	$	(1,310)

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate swaps are to add stability to interest expense and to manage its exposure to interest rate movements.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income and subsequently reclassified to interest expense in the same periods during which the hedged transaction affects earnings.

Amounts reported in accumulated other comprehensive income related to derivatives designated as qualifying cash flow hedges will be reclassified to interest expense as interest payments are made on the Company’s variable rate debt. The Company estimates that approximately $8.9 million will be reclassified from accumulated other comprehensive income as a decrease to interest expense over the next 12 months.

The following table summarizes the effect of cash flow hedge accounting and the location of amounts related to the Company’s derivatives in the consolidated financial statements for the three months ended March 31, 2026 and 2025.


	Three months ended March 31,
Effect of Cash Flow Hedge Accounting (in thousands)	2026		2025
Income (loss) recognized in accumulated other comprehensive income on interest rate swaps	$	5,943	$	(5,104)
Income reclassified from accumulated other comprehensive income into income as interest expense	$	3,039	$	5,877
Total interest expense presented in the Consolidated Statements of Operations in which the effect of cash flow hedges are recorded	$	35,885	$	32,529

Credit-risk-related Contingent Features

The Company has agreements with each of its derivative counterparties that contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company’s default on the indebtedness.

As of March 31, 2026, the Company had not breached the provisions of these agreements and had not posted any collateral related to these agreements. If the Company had breached any of these provisions, it would be required to settle its obligations under the agreements at their termination value.

Fair Value of Interest Rate Swaps

The Company’s valuation of the interest rate swaps is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs including interest rate curves. The fair values of interest rate swaps are determined by using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Table of Contents

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company or its counterparties. However, as of March 31, 2026 and December 31, 2025, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

The following table summarizes the Company’s financial instruments that were recorded at fair value on a recurring basis as of March 31, 2026 and December 31, 2025.

Certain Definitions

In this report:

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

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

“GAAP” means generally accepted accounting principles in the United States of America.

“New Lease” means a lease that is signed for an initial term equal to or greater than 12 months for any vacant space, including a lease signed by a new tenant or an existing tenant that is expanding into new (additional) space.

“Occupancy rate” means the percentage of total leasable square footage for which either revenue recognition has commenced in accordance with GAAP or the lease term has commenced as of the close of the reporting period, whichever occurs earlier.

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

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

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

“Stabilization” for properties under development or being redeveloped means the earlier of achieving 90% occupancy or 12 months after completion. With respect to properties acquired and immediately added to the Value Add Portfolio, (i) if acquired with less than 75% occupancy as of the acquisition date, Stabilization will occur upon the earlier of achieving 90% occupancy or 12 months from the acquisition date, or (ii) if acquired and will be less than 75% occupied due to known move-outs within two years of the acquisition date, Stabilization will occur upon the earlier of achieving 90% occupancy after the known move-outs have occurred or 12 months after the known move-outs have occurred.

“Total annualized base rental revenue” means the monthly base cash rent for the applicable property or properties as of March 31, 2026 (which is different from rent calculated in accordance with GAAP for purposes of our financial statements),

multiplied by 12. If a tenant is in a free rent period as of March 31, 2026, the annualized rent is calculated based on the first contractual monthly base rent amount multiplied by 12.

“Value Add Portfolio” means our properties that meet any of the following criteria: (i) less than 75% occupied as of the acquisition date; (ii) will be less than 75% occupied due to known move-outs within two years of the acquisition date; (iii) out of service with significant physical renovation of the asset; or (iv) development.

“Weighted Average Lease Term” means the contractual lease term in years, assuming that tenants exercise no renewal options, purchase options, or early termination rights, as of the lease start date weighted by square footage. Weighted Average Lease Term related to acquired assets reflects the remaining lease term in years as of the acquisition date weighted by square footage.

Overview

We are a REIT focused on the acquisition, ownership, development, and operation of industrial properties throughout the United States. Our platform is designed to (i) identify properties for acquisition that offer relative value across CBRE-EA Tier 1 industrial property types and tenants through the principled application of our proprietary risk assessment model, (ii) provide growth through sophisticated industrial operation and an attractive opportunity set, and (iii) capitalize our business appropriately given the characteristics of our assets. We are a Maryland corporation and our common stock is publicly traded on the New York Stock Exchange under the symbol “STAG.”

We are organized and conduct our operations to maintain our qualification as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and generally are not subject to federal income tax to the extent we currently distribute our income to our stockholders and maintain our qualification as a REIT. We remain subject to state and local taxes on our income and property and to U.S. federal income and excise taxes on our undistributed income.

Factors That May Influence Future Results of Operations

Our ability to increase revenues or cash flow will depend in part on our (i) external growth, specifically acquisition activity, and (ii) internal growth, specifically occupancy and rental rates on our portfolio, as well as development activity. A variety of other factors, including those noted below, also affect our future results of operations.

Outlook

The industrial real estate business is affected by general macro-economic trends including recent changes in interest rates, inflation, trade policies, fiscal policy, technology (e.g. artificial intelligence), and geopolitical tensions, including ongoing military conflicts in the Middle East. These factors are key drivers of financial market volatility and raise concerns about a slowing global economy. In 2025, U.S. real gross domestic product grew 2.1% compared to 2.8% in 2024. Labor conditions softened in 2025 and the first quarter of 2026, with the unemployment rate edging up to 4.3% by March 2026 from 4.1% in December 2024. In the first quarter of 2026, the Federal Open Market Committee maintained a federal funds target range of 3.5% to 3.75%. Going forward, the general consensus among economists is a higher risk of recession or stagflation. Trade policies, geopolitical tensions, and macro-economic conditions continue to evolve and could result in tighter credit conditions, weakening tenant cash flows, and rising vacancy rates. Given the current uncertainty and events discussed above, our acquisition activity to date in 2026 has been slow relative to our historical acquisition pace.

On the other hand, demographic/consumer trends, geopolitical uncertainty and recent legislation supporting U.S. infrastructure may accelerate trends that support stronger long-term demand for industrial space, including:

•the continued growth of e-commerce (as compared to the traditional retail store distribution model) and the concomitant demand by e-commerce industry participants for well-located, functional distribution space;

•the increasing attractiveness of the United States as a manufacturing and distribution location because of the size of the U.S. consumer market, an increase in overseas labor costs, policies that promote domestic and regional manufacturing “onshoring and nearshoring”, a desire for greater supply chain resilience and redundancy which is driving higher inventory to sales ratios and greater domestic warehouse demand over the long term (i.e. the shortening and fattening of the supply chain); and

•the general quality of the transportation infrastructure in the United States.

Table of Contents

Overall, demand across the industrial market is gradually recovering toward the long-term average. Vacancy and availability rates are near historical standards in many markets. The supply pipeline remains active, albeit lower volume and more notably concentrated in build-to-suits. Speculative construction starts remain low as a result of both moderate demand and volatile capital markets.

Our portfolio is diversified across geographies, tenant industries and lease terms. We believe that the current economic environment, while volatile, provides us with an opportunity to demonstrate the strength of our portfolio arising from its diversification. Specifically, we believe our portfolio should benefit from competitive rental rates and strong occupancy. In addition to our diversified portfolio, we believe that certain characteristics of our business and capital structure should position us well in an uncertain environment, including our minimal floating rate debt exposure (taking into account our hedging activities), strong banking relationships and liquidity, and access to capital.

Conditions in Our Markets

The buildings in our portfolio are located in markets throughout the United States. Positive or negative changes in economic or other conditions, new supply, adverse weather conditions, natural disasters, epidemics, and other factors in these markets may affect our overall performance.

Rental Income

We receive income primarily in the form of rental income from the tenants who occupy our buildings. The amount of rental income generated by the buildings in our portfolio depends principally on occupancy and rental rates.

Future economic downturns or regional downturns affecting our submarkets that impair our ability to renew or re-lease space and the ability of our tenants to fulfill their lease commitments, as in the case of tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our buildings. Our ability to lease our properties and the attendant rental rate is dependent upon, among other things, (i) the overall economy, (ii) the supply/demand dynamic in our markets, (iii) the quality of our properties, including age, clear height, and configuration, and (iv) our tenants’ ability to meet their contractual obligations to us.

The following table summarizes the Operating Portfolio leases that commenced during the three months ended March 31, 2026. Any rental concessions in such leases are accounted for on a straight-line basis over the term of the lease.


Operating Portfolio	Square Feet	Cash Basis Rent Per Square Foot		SL Rent Per Square Foot		Total Costs Per Square Foot(1)		Cash Rent Change		SL Rent Change		Weighted Average Lease Term (years)	Rental Concessions per Square Foot(2)

(1)“Total Costs” means the costs for improvements of vacant and renewal spaces, as well as the contingent-based legal fees and commissions for leasing transactions. Total Costs per square foot represent the total costs expected to be incurred on the leases that commenced during the period and do not reflect actual expenditures for the period.

(2)Represents the total rental concessions for the entire lease term.

Additionally, for the three months ended March 31, 2026, leases commenced totaling 181,024 related to the Value Add Portfolio and first generation leasing. These leases are excluded from the Operating Portfolio statistics above.

Property Operating Expenses

Our property operating expenses generally consist of utilities, real estate taxes, management fees, insurance, and site repair and maintenance costs. For the majority of our tenants, our property operating expenses are controlled, in part, by the triple net provisions in tenant leases. In our triple net leases, the tenant is responsible for all aspects of and costs related to the building and its operation during the lease term, including utilities, taxes, insurance, and maintenance costs, but typically excluding roof and building structure. However, we also have modified gross leases and gross leases, as well as leases with expense caps, in our building portfolio, which may require us to absorb certain building related expenses of our tenants. In our modified gross leases, we are responsible for certain building related expenses during the lease term, but most of the expenses are passed through to the tenant for reimbursement to us. In our gross leases, we are responsible for all expenses related to the building and

its operation during the lease term. Our overall performance will be affected by the extent to which we are able to pass-through property operating expenses to our tenants.

Scheduled Lease Expirations

Our ability to re-lease space subject to expiring leases will impact our results of operations and is affected by economic and competitive conditions in our markets and by the desirability of our individual buildings. Leases that comprise approximately 8% of our total annualized base rental revenue will expire during the period from April 1, 2026 to March 31, 2027, excluding month-to-month leases. We assume, based upon internal renewal probability estimates, that some of our tenants will renew and others will vacate and the associated space will be re-let subject to downtime assumptions. Using the aforementioned assumptions, we expect that the rental rates on the respective new leases will be greater than the rates under existing leases expiring during the period April 1, 2026 to March 31, 2027, thereby resulting in an increase in revenue from the same space.

The following table summarizes lease expirations for leases in place as of March 31, 2026, plus available space, for each of the ten calendar years beginning with 2026 and thereafter in our portfolio. The information in the table assumes that tenants do not exercise renewal options or early termination rights.

Critical Accounting Policies

See “Critical Accounting Policies” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2025 for a discussion of our critical accounting policies and estimates.

Results of Operations

The following discussion of the results of our same store (as defined below) net operating income (“NOI”) should be read in conjunction with our consolidated financial statements included in this report. For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see “Non-GAAP Financial Measures” below. Same store results are useful to investors in evaluating our performance because they provide information relating to changes in building-level operating performance without taking into account the effects of acquisitions or dispositions. We encourage the reader to not only look at our same store results, but also our total portfolio results, due to historic and future growth.

We define same store properties as properties that were in the Operating Portfolio for the entirety of the comparative periods presented. The results for same store properties exclude termination fees, solar income, and other income adjustments. Same store properties exclude Operating Portfolio properties with expansions placed into service on or after January 1, 2025. On March 31, 2026, we owned 569 industrial buildings consisting of approximately 111.8 million square feet and representing approximately 93.0% of our total portfolio, that are considered our same store portfolio in the analysis below. Same store occupancy decreased approximately 1.2% to 96.6% as of March 31, 2026 compared to 97.8% as of March 31, 2025.

Comparison of the three months ended March 31, 2026 to the three months ended March 31, 2025

The following table summarizes selected operating information for our same store portfolio and our total portfolio for the three months ended March 31, 2026 and 2025 (dollars in thousands).

Net Income

Net income for our total portfolio decreased by approximately $30.0 million, or 32.2%, to approximately $63.3 million for the three months ended March 31, 2026 compared to approximately $93.4 million for the three months ended March 31, 2025.

Same Store Total Operating Revenue

Same store total operating revenue consists primarily of rental income from (i) fixed lease payments, variable lease payments, straight-line rental income, and above and below market lease amortization from our properties (“lease income”), and (ii) other tenant billings for insurance, real estate taxes and certain other expenses (“other billings”).

For a detailed reconciliation of our same store total operating revenue to net income, see the table above.

Same store rental income, which includes lease income and other billings as discussed below, increased by approximately $7.8 million, or 3.9%, to approximately $207.4 million for the three months ended March 31, 2026 compared to approximately $199.6 million for the three months ended March 31, 2025.

Same store lease income increased by approximately $6.5 million, or 4.0%, to approximately $167.2 million for the three months ended March 31, 2026 compared to approximately $160.7 million for the three months ended March 31, 2025. The increase was primarily due to the execution of new leases and lease renewals with existing tenants of approximately $8.9 million. The increase was partially offset by the reduction of base rent of approximately $2.2 million due to tenant vacancies and a net increase in the amortization of net above market leases of approximately $0.2 million.

Same store other billings increased by approximately $1.3 million, or 3.3%, to approximately $40.2 million for the three months ended March 31, 2026 compared to approximately $38.9 million for the three months ended March 31, 2025. Approximately $0.8 million was due to an increase in real estate taxes levied by the taxing authority. Additionally, there was an increase of approximately $0.5 million in expense reimbursements, which was primarily due to an increase in corresponding expenses.

Same Store Operating Expenses

Same store operating expenses consist primarily of property operating expenses and real estate taxes and insurance.

For a detailed reconciliation of our same store operating expenses to net income, see the table above.

Total same store property operating expenses increased by approximately $1.3 million, or 3.1%, to approximately $43.2 million for the three months ended March 31, 2026 compared to approximately $41.9 million for the three months ended March 31, 2025. The increase was due to increases in other expenses, repairs and maintenance, utility expense, and real estate tax expense of approximately $0.7 million, $0.5 million, $0.3 million, and $0.2 million, respectively. These increases were partially offset by a reduction of insurance expense of approximately $0.3 million and snow removal expense of $0.2 million

Acquisitions and Dispositions Net Operating Income

For a detailed reconciliation of our acquisitions and dispositions NOI to net income, see the table above.

Subsequent to January 1, 2025, we acquired 14 buildings consisting of approximately 4.5 million square feet and sold 12 buildings consisting of approximately 2.8 million square feet. For the three months ended March 31, 2026 and 2025, the buildings acquired after January 1, 2025 contributed approximately $8.9 million and $0.4 million to NOI, respectively. For the three months ended March 31, 2026 and 2025, the buildings sold after January 1, 2025 contributed approximately $0.1 million and $2.2 million to NOI, respectively. Refer to Note 3 in the accompanying Notes to Consolidated Financial Statements for additional discussion regarding buildings acquired or sold.

Other Net Operating Income

Other assets include our Value Add Portfolio, buildings classified as held for sale, and Operating Portfolio buildings with expansions placed in service or transferred from the Value Add Portfolio to the Operating Portfolio after January 1, 2025. Other NOI also includes termination, solar, and other income adjustments from buildings in our same store portfolio.

Table of Contents

For a detailed reconciliation of our other NOI to net income, see the table above.

These buildings contributed approximately $2.8 million and $1.0 million to NOI for the three months ended March 31, 2026 and 2025, respectively. Additionally, there was approximately $0.7 million and $0.4 million of termination, solar, and other income adjustments from certain buildings in our same store portfolio for the three months ended March 31, 2026 and 2025, respectively.

Total Other Expenses

Total other expenses consist of general and administrative, depreciation and amortization, and other expenses.

Total other expenses increased approximately $5.1 million, or 5.8%, to approximately $92.9 million for the three months ended March 31, 2026 compared to approximately $87.8 million for the three months ended March 31, 2025. The increase was primarily attributable to an increase in depreciation and amortization of approximately $4.7 million due to an increase in the depreciable asset base from net acquisitions and completed development projects placed into service after March 31, 2025.

Total Other Income (Expense)

Total other income (expense) consists of interest and other income, interest expense, gain on involuntary conversion, and gain on the sales of rental property, net. Interest expense includes interest incurred during the period as well as adjustments related to amortization of financing fees and debt issuance costs, and amortization of fair market value adjustments associated with the assumption of debt.

Total other income (expense) decreased approximately $39.9 million, or 207.5%, to approximately $20.7 million total other expense for the three months ended March 31, 2026 compared to approximately $19.2 million of other income for the three months ended March 31, 2025. The decrease was primarily attributable to a decrease in the gain on the sale of rental property, net, of approximately $34.8 million, as well as an increase in interest expense of approximately $3.4 million, which was primarily attributable to the issuance of $550.0 million of unsecured notes on June 25, 2025. Additionally, there was a decrease in the gain on involuntary conversion of approximately $1.9 million that occurred during the three months ended March 31, 2025, which did not occur during the three months ended March 31, 2026.

Non-GAAP Financial Measures

In this report, we disclose funds from operations (“FFO”) and NOI, which meet the definition of “non-GAAP financial measures” as set forth in Item 10(e) of Regulation S-K promulgated by the Securities and Exchange Commission (“SEC”). As a result, we are required to include in this report a statement of why management believes that presentation of these measures provides useful information to investors.

Funds From Operations

FFO should not be considered as an alternative to net income (determined in accordance with GAAP) as an indication of our performance, and we believe that to understand our performance further, FFO should be compared with our reported net income (loss) in accordance with GAAP, as presented in our consolidated financial statements included in this report.

We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“Nareit”). FFO represents GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating buildings, impairment write-downs of depreciable real estate, real estate related depreciation and amortization (excluding amortization of deferred financing costs and fair market value of debt adjustment) and after adjustments for unconsolidated partnerships and joint ventures.

Management uses FFO as a supplemental performance measure because it is a widely recognized measure of the performance of REITs. FFO may be used by investors as a basis to compare our operating performance with that of other REITs.

However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our buildings that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our buildings, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. In addition, other REITs may not calculate FFO

Net Operating Income

We consider NOI to be an appropriate supplemental performance measure to net income (loss) because we believe it helps investors and management understand the core operations of our buildings. NOI is defined as rental income, which includes billings for common area maintenance, real estate taxes and insurance, less property expenses, real estate tax expense and insurance expense. NOI should not be viewed as an alternative measure of our financial performance since it excludes expenses which could materially impact our results of operations. Further, our NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating NOI.

The following table sets forth a reconciliation of our NOI for the periods presented to net income, the nearest GAAP equivalent.

Cash Flows

Comparison of the three months ended March 31, 2026 to the three months ended March 31, 2025

The following table summarizes our cash flows for the three months ended March 31, 2026 compared to the three months ended March 31, 2025.


	Three months ended March 31,				Change
Cash Flows (dollars in thousands)	2026		2025		$		%
Net cash provided by operating activities	$	117,440	$	103,540	$	13,900	13.4	%
Net cash used in investing activities	$	92,016	$	24,926	$	67,090	269.2	%
Net cash used in financing activities	$	87,153	$	67,954	$	19,199	28.3	%

Net cash provided by operating activities increased approximately $13.9 million to approximately $117.4 million for the three months ended March 31, 2026 compared to approximately $103.5 million for the three months ended March 31, 2025. The increase was attributable to fluctuations in working capital due to timing of payments and rental receipts.

Table of Contents

Net cash used in investing activities increased approximately $67.1 million to approximately $92.0 million for the three months ended March 31, 2026 compared to approximately $24.9 million for the three months ended March 31, 2025. The increase was primarily attributable to a decrease in proceeds from sale of rental property, net of approximately $34.3 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025, as well as an increase in the acquisition of rental property of approximately $37.8 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase was partially offset by a decrease in cash paid for additions of land and buildings and improvements related to development and other capital expenditures of approximately $5.0 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025.

Net cash used in financing activities increased approximately $19.2 million to approximately $87.2 million for the three months ended March 31, 2026 compared to approximately $68.0 million for the three months ended March 31, 2025. The increase was primarily attributable to an increase in net cash outflow of approximately $165.0 million under our unsecured credit facility during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. This increase was partially offset by the repayment of unsecured notes of $100.0 million during the three months ended March 31, 2025, which did not occur during the three months ended March 31, 2026. The increase was also partially offset by a decrease of approximately $46.7 million in dividends and distributions paid, which was attributable to our change in 2026 to quarterly dividend payments, compared to monthly dividend payments in 2025.

Liquidity and Capital Resources

We believe that our liquidity needs will be satisfied through cash flows generated by operations, disposition proceeds, and financing activities. Operating cash flow from rental income, expense recoveries from tenants, and other income from operations are our principal sources of funds to pay operating expenses, debt service, recurring capital expenditures, and the distributions required to maintain our REIT qualification. We primarily rely on the capital markets (equity and debt securities and bank borrowings) to fund our acquisition activity. We seek to increase cash flows from our properties by maintaining quality building standards that promote high occupancy rates and permit increases in rental rates, while reducing tenant turnover and controlling operating expenses. We believe that our revenue, together with proceeds from building sales and equity and debt financings, will continue to provide funds for our short-term and medium-term liquidity needs.

Our short-term liquidity requirements consist primarily of funds necessary to pay for operating expenses and other expenditures directly associated with our buildings, including interest expense, interest rate swap payments, scheduled principal payments on outstanding indebtedness, property acquisitions under contract, general and administrative expenses, and capital expenditures including development projects, tenant improvements and leasing commissions.

Our long-term liquidity needs, in addition to recurring short-term liquidity needs as discussed above, consist primarily of funds necessary to pay for property acquisitions and scheduled debt maturities. We intend to satisfy our long-term liquidity needs through cash flow from operations, the issuance of equity or debt securities, other borrowings, property dispositions, or, in connection with acquisitions of certain additional buildings, the issuance of common units in our Operating Partnership.

As of March 31, 2026, we had total immediate liquidity of approximately $805.7 million, comprised of approximately $8.9 million of cash and cash equivalents and approximately $796.8 million of immediate availability on our unsecured credit facility.

In addition, we require funds to pay dividends to holders of our common stock and common units in our Operating Partnership. Any future dividends on our common stock are declared in the sole discretion of our board of directors, subject to the distribution requirements to maintain our REIT status for federal income tax purposes, and may be reduced or stopped for any reason, including to use funds for other liquidity requirements.

Indebtedness Outstanding

The following table summarizes certain information with respect to our indebtedness outstanding as of March 31, 2026.


Indebtedness (dollars in thousands)	Principal Outstanding March 31, 2026		Weighted Average Interest Rate(1)		Weighted Average Years(2)


Unsecured credit facility	$	200,000	Term SOFR + 0.775%		3.4







Unsecured term loans	1,025,000		3.59	%	2.9

















Unsecured notes	1,975,000		4.84	%	5.2





Mortgage note	4,042		3.71	%	13.5



Total / weighted average	$	3,204,042	4.42	%	4.3

(2)The weighted average years represents the remaining maturity in years on the principal outstanding as of March 31, 2026 , and assumes that any extension options that are exercisable at our discretion, subject to certain terms and conditions, have been exercised

The aggregate undrawn nominal commitments on our unsecured credit facility as of March 31, 2026 was approximately $796.8 million, including issued letters of credit. Our actual borrowing capacity at any given point in time may be less and is restricted to a maximum amount based on our debt covenant compliance.

Our unsecured credit facility, unsecured term loans, unsecured notes, and mortgage note are subject to ongoing compliance with a number of financial and other covenants. As of March 31, 2026, we were in compliance with the applicable financial covenants.

The following table summarizes our debt capital structure as of March 31, 2026.


Debt Capital Structure	March 31, 2026
Total principal outstanding (in thousands)	$	3,204,042
Weighted average duration (years)	4.3

% Secured debt	0.1		%
% Debt maturing next 12 months	9.4		%
Net Debt to Real Estate Cost Basis(1)	38.1		%

(1)“Net Debt” means amounts outstanding under our unsecured credit facility, unsecured term loans, unsecured notes, and mortgage note, less cash and cash equivalents. “Real Estate Cost Basis” means the book value of rental property and deferred leasing intangibles, exclusive of the related accumulated depreciation and amortization.

We regularly pursue new financing opportunities to ensure an appropriate balance sheet position. As a result of these dedicated efforts, we are confident in our ability to meet future debt maturities and fund acquisitions. We believe that our current balance sheet is in an adequate position at the date of this filing, despite possible volatility in the credit markets.

Our interest rate exposure on our floating rate debt is managed through the use of interest rate swaps, which fix the rate of our long term floating rate debt. For a detailed discussion on our use of interest rate swaps, see “Interest Rate Risk” below.

Equity

Common Stock

Pursuant to the equity distribution agreements for our ATM common stock offering program, we may from time to time sell common stock through sales agents and their affiliates, including shares sold on a forward basis under forward sale agreements. There was no activity for the ATM common stock offering program during the three months ended March 31, 2026, except for the shares sold on a forward basis, as discussed below.

Table of Contents

The following table summarizes our ATM common stock offering program as of March 31, 2026.

(1) The ATM common stock offering program was originally implemented on February 17, 2022, and had an initial maximum aggregate offering price of $750 million. On February 13, 2025, following the filing of a new shelf registration statement, we carried forward the ATM common stock offering program to the new registration statement, at which time the remaining maximum aggregate offering price (that is, the amount carried forward) was less than $750 million.

The following table summarizes the activity for shares sold on a forward basis under the ATM common stock offering program and shares settled during the three months March 31, 2026.


Forward Sale Agreements	Shares	Gross Sales (in thousands)		Weighted Average Gross Sales Price Per Share		Weighted Average Net Sales Price Per Share		Sales Commissions Per Share(1)
Forward Sale Agreements Outstanding at December 31, 2025	—	$	—
New forward sale agreements	160,441	6,145		$	38.30	$	37.92	$	0.38
Forward sale agreements settled	—	—
Forward Sale Agreements Outstanding at March 31, 2026	160,441	$	6,145

(1)Upon a forward sale, the equity distribution agent typically earns a sales commission of 1% of the gross sales price.

We initially do not receive any proceeds from the sales of shares on a forward basis. We may physically settle the applicable forward sale agreements on one or more dates prior to the respective scheduled maturity dates, at which point we would receive the proceeds net of certain costs; provided, however, generally we may elect to cash settle or net share settle such forward sale agreements at any time through the respective scheduled maturity dates, which is typically one year from the respective trade dates.

Noncontrolling Interest

We own our interests in all of our properties and conduct substantially all of our business through the Operating Partnership. We are the sole member of the sole general partner of the Operating Partnership. As of March 31, 2026, we owned approximately 98.0% of the common units in the Operating Partnership, and our current and former executive officers, directors, senior employees and their affiliates, and third parties that contributed properties to us in exchange for common units in the Operating Partnership owned the remaining 2.0%.

We also own joint ventures with third parties primarily engaged in the development and eventual operation of industrial real estate properties. At March 31, 2026, we held a 97.4% interest in a joint venture located in Reno, Nevada, a 95.1% interest in a joint venture located in Concord, North Carolina, and a 97.1% interest in a joint venture located in Shepherdsville, Kentucky.

Interest Rate Risk

We use interest rate swaps to fix the rate of our variable rate debt. As of March 31, 2026, all of our outstanding variable rate debt, with the exception of our unsecured credit facility, was fixed with interest rate swaps through maturity.

We recognize all derivatives on the balance sheet at fair value. If the derivative is designated as a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in other comprehensive income (loss), which is a component of equity. Derivatives that are not designated as hedges must be adjusted to fair value and the changes in fair value must be reflected as income or expense.

We have established criteria for suitable counterparties in relation to various specific types of risk. We only use counterparties that have a credit rating of no lower than investment grade at swap inception from Moody’s Investor Services, Standard & Poor’s, or Fitch Ratings or other nationally recognized rating agencies.

The swaps are all designated as cash flow hedges of interest rate risk, and all are valued as Level 2 financial instruments. Level 2 financial instruments are defined as significant other observable inputs. As of March 31, 2026, 14 of our interest rate swaps outstanding were in an asset position of approximately $15.6 million and four of our interest rate swaps were in a liability position of approximately $0.5 million, including any adjustment for nonperformance risk related to these agreements.

Table of Contents

As of March 31, 2026, we had approximately $1,225.0 million of variable rate debt. As of March 31, 2026, all of our outstanding variable rate debt, with the exception of our unsecured credit facility, was fixed with interest rate swaps through initial maturity. To the extent interest rates increase, interest costs on our floating rate debt not fixed with interest rate swaps will increase, which could adversely affect our cash flow and our ability to pay principal and interest on our debt and our ability to make distributions to our security holders. From time to time, we may enter into interest rate swap agreements and other interest rate hedging contracts, including swaps, caps and floors. In addition, an increase in interest rates could decrease the amounts third parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions.

Off-balance Sheet Arrangements

As of March 31, 2026, we had letters of credit related to development projects and certain other agreements of approximately $3.2 million. As of March 31, 2026, we had no other material off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. The primary market risk we are exposed to is interest rate risk. We have used derivative financial instruments to manage, or hedge, interest rate risks related to our borrowings, primarily through interest rate swaps.

As of March 31, 2026, we had $1,225.0 million of variable rate debt outstanding. As of March 31, 2026, all of our outstanding variable rate debt, with the exception of our unsecured credit facility which had a balance of $200.0 million, was fixed with interest rate swaps through initial maturity. To the extent we undertake additional variable rate indebtedness, if interest rates increase, then so will the interest costs on our unhedged variable rate debt, which could adversely affect our cash flow and our ability to pay principal and interest on our debt and our ability to make distributions to our security holders. Further, rising interest rates could significantly increase our future interest expense. From time to time, we enter into interest rate swap agreements and other interest rate hedging contracts, including swaps, caps and floors. While these agreements are intended to lessen the impact of rising interest rates on us, they also expose us to the risk that the other parties to the agreements will not perform, we could incur significant costs associated with the settlement of the agreements, the agreements will be unenforceable and the underlying transactions will fail to qualify as highly-effective cash flow hedges under GAAP. In addition, an increase in interest rates could decrease the amounts third parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions. If interest rates increased by 100 basis points and assuming we had an outstanding balance of $200.0 million on our unsecured credit facility for the three months ended March 31, 2026, our interest expense would have increased by approximately $0.5 million for the three months ended March 31, 2026.
