(1)Interest rate as of September 30, 2023. At September 30, 2023, the one-month Term Secured Overnight Financing Rate (“Term SOFR”) was 5.31899%. The current interest rate is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums or discounts. The spread over the applicable rate for the Company’s unsecured credit facility and unsecured term loans is based on the Company’s debt rating and leverage ratio, as defined in the respective loan agreements.
(2)The unsecured credit facility has a stated interest rate of one-month Term SOFR plus a 0.10% adjustment and a spread of 0.775%, less a sustainability-related interest rate adjustment of 0.02%. The unsecured term loans have a stated interest rate of one-month Term SOFR plus a 0.10% adjustment and a spread of 0.85%, less a sustainability-related interest rate adjustment of 0.02%. As of September 30, 2023, one-month Term SOFR for the Unsecured Term Loans A, F, G, H, and I was swapped to a fixed rate of 1.31%, 2.11%, 0.95%, 2.90%, and 2.66%, respectively (which includes the 0.10% adjustment). One-month Term SOFR for the Unsecured Term Loan H will be swapped to a fixed rate of 2.50% effective January 12, 2024.
(3)Prepayment terms consist of (i) pre-payable with no penalty; (ii) pre-payable with penalty; (iii) pre-payable without penalty three months prior to the maturity date.
(4)The capacity of the unsecured credit facility is $1.0 billion. Deferred financing fees and debt issuance costs, net of accumulated amortization related to the unsecured credit facility of approximately $3.8 million and $5.2 million are included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, respectively. The initial maturity date is October 24, 2025, or such later date which may be extended pursuant to two six-month extension options exercisable by the Company in its discretion upon advance written notice. Exercise of each six-month option is subject to the following conditions: (i) absence of a default immediately before the extension and immediately after
11

giving effect to the extension; (ii) accuracy of representations and warranties as of the extension date (both immediately before and after the extension), as if made on the extension date; and (iii) payment of a fee. Neither extension option is subject to lender consent, assuming proper notice and satisfaction of the conditions. The Company is required to pay a facility fee on the aggregate commitment amount (currently $1.0 billion) at a rate per annum of 0.1% to 0.3%, depending on our debt rating, as defined in the credit agreement. The facility fee is due and payable quarterly.
(5)The weighted average interest rate was calculated using the fixed interest rate swapped on the notional amount of $1,025.0 million of debt and is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums or discounts.

The aggregate undrawn nominal commitment on the unsecured credit facility as of September 30, 2023 was approximately $671.7 million, including issued letters of credit. The Company’s actual borrowing capacity at any given point in time may be restricted to a maximum amount based on the Company’s debt covenant compliance. Total accrued interest for the Company’s indebtedness was approximately $17.2 million and $13.1 million as of September 30, 2023 and December 31, 2022, respectively, and is included in accounts payable, accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets.

The following table summarizes the costs included in interest expense related to the Company’s debt arrangements on the accompanying Consolidated Statement of Operations for the three and nine months ended September 30, 2023 and 2022.

Debt Activity

On January 5, 2023, the Company redeemed in full at maturity the $100.0 million in aggregate principal amount of the Series F Unsecured Notes with a fixed interest rate of 3.98%.

On January 19, 2023, the sustainability-related interest rate adjustment for the Unsecured Term Loan H and Unsecured Term Loan I went into effect because of the improvement in the Company’s 2022 public disclosure assessment score from the Global Real Estate Sustainability Benchmark (GRESB), as compared to the 2021 score. The interest rate adjustment, a 0.02% interest rate reduction for each instrument, will end on June 29, 2024, in accordance with the respective loan agreements.

Financial Covenant Considerations

The Company was in compliance with all such applicable restrictions and financial and other covenants as of September 30, 2023 and December 31, 2022 related to its unsecured credit facility, unsecured term loans, unsecured notes, and mortgage notes. The real estate net book value of the properties that are collateral for the Company’s debt arrangements was approximately $14.8 million and $14.8 million at September 30, 2023 and December 31, 2022, respectively, and is limited to senior, property-level secured debt financing arrangements.

Fair Value of Debt

The following table summarizes the aggregate principal amount outstanding under the Company’s debt arrangements and the corresponding estimate of fair value as of September 30, 2023 and December 31, 2022.

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 September 30, 2023, the Company had 21 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 components to effectively fixed interest rates, and the Company has concluded that each of the hedging relationships are highly effective. The following table summarizes the fair value of the interest rate swaps as of September 30, 2023 and December 31, 2022.

Balance Sheet Line Item (in thousands)Notional Amount September 30, 2023Fair Value September 30, 2023Notional Amount December 31, 2022Fair Value December 31, 2022

Interest rate swaps-Liability$ $ $ $ 

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 (loss) 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 $35.9 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 Company’s derivatives in the consolidated financial statements for the three and nine months ended September 30, 2023 and 2022.

Total interest expense presented in the Consolidated Statements of Operations in which the effects of cash flow hedges are recorded$23,753 $21,155 $69,225 $56,310 

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.

13

As of September 30, 2023, the Company had not breached the provisions of these agreements and had not posted any collateral related to these agreements.

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 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.

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 September 30, 2023 and December 31, 2022, 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 September 30, 2023 and December 31, 2022. There were no financial instruments in a liability position at September 30, 2023 and December 31, 2022.

LTIP Units

The Company granted LTIP units under the 2011 Plan on January 11, 2023 to non-employee, independent directors, which will vest on January 1, 2024, subject to the recipient’s continued service. The Company granted LTIP units under the 2011 Plan on January 11, 2023 to certain executive officers and senior employees of the Company, which will vest in equal installments on a quarterly basis over four years, with the first vesting date having been March 31, 2023, subject to the recipient’s continued employment. Refer to Note 8 for a discussion of the LTIP units granted on January 11, 2023 pursuant to the 2020 performance units.

On March 13, 2023, the Company executed an employment agreement with Steven T. Kimball to serve as the Company's Executive Vice President of Real Estate Operations, effective March 31, 2023. On March 31, 2023, pursuant to the 2011 Plan, the Company awarded Mr. Kimball an initial LTIP unit grant equal in value to approximately $0.6 million, which equated to 19,345 LTIP units, which will vest in equal installments on a quarterly basis over four years, with the first vesting date having been March 31, 2023, subject to Mr. Kimball’s continued employment.

The fair value of the LTIP units as of the grant date was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the LTIP units are based on Level 3 inputs and non-recurring fair value measurements. The following table summarizes the assumptions used in valuing such LTIP units granted during the nine months ended September 30, 2023 (excluding the LTIP units granted pursuant to the 2020 performance units discussed in Note 8).

The expected stock price volatility is based on a mix of the historical and implied volatilities of the Company and certain peer group companies. The expected dividend yield is based on the Company’s average historical dividend yield and the dividend yield as of the valuation date for each award. The risk-free interest rate is based on U.S. Treasury note yields matching a three-year time period.

8. Equity Incentive Plan

On January 11, 2023, the compensation committee of the board of directors approved and the Company granted performance units under the 2011 Plan to the executive officers and certain key employees of the Company. The terms of the performance units granted on January 11, 2023 are substantially the same as the terms of the performance units granted in January 2022, 2021, and 2020, except that the measuring period commenced on January 1, 2023 and ends on December 31, 2025, and the size-based peer group was eliminated. The target amount of the performance units granted on January 11, 2023 is nominally allocated as follows: (i) 50% to the Company’s total stockholder return (“TSR”) compared to the TSR of an industry peer group; and (ii) 50% to the Company’s TSR compared to the TSR of the companies in the MSCI US REIT Index.

On March 31, 2023, in connection with the execution of the employment agreement discussed in Note 7, the Company granted Mr. Kimball performance units under the 2011 Plan with a target grant date fair value equal to approximately $0.6 million. The terms and measuring period of the performance units granted to Mr. Kimball are the same as the performance units granted on January 11, 2023.

On April 25, 2023, the Company’s stockholders approved an amendment (the “Amendment”) to the 2011 Plan which increased the total number of shares of common stock of the Company authorized and reserved for issuance under the 2011 Plan by 3,500,000 shares to an aggregate of 10,142,461 shares of common stock, subject to certain adjustments as described in the 2011 Plan. The Amendment also extended the expiration date of the 2011 Plan from April 30, 2028 to April 24, 2033.

17

The fair value of the performance units as of the grant date was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the performance units is based on Level 3 inputs and non-recurring fair value measurements. The performance unit equity compensation expense is recognized ratably from the grant date into earnings over the vesting period. The following table summarizes the assumptions used in valuing the performance units granted during the nine months ended September 30, 2023.

Performance UnitsAssumptions
Grant dateMarch 31, 2023January 11, 2023
Expected stock price volatility25.4 %37.4 %
Expected dividend yield4.0 %4.0 %
Risk-free interest rate3.8725 %3.9060 %
Fair value of performance units grant (in thousands)$609 $4,517 

The expected stock price volatility is based on a mix of the historical and implied volatilities of the Company and certain peer group companies. The expected dividend yield is based on the Company’s average historical dividend yield and the dividend yield as of the valuation date for each award. The risk-free interest rate is based on U.S. Treasury note yields matching the time period of the grant date to the end of the measuring period.

On December 31, 2022, the measuring period for the 2020 performance units concluded, and it was determined that the Company’s TSR exceeded the threshold percentage and return hurdle. The following table summarizes the issuances of LTIP units and shares of common stock approved by the compensation committee of the board of directors and issued upon the settlement of the 2020 performance units at the conclusion of the applicable measuring period during the nine months ended September 30, 2023.

9. Leases

Lessor Leases

The Company has operating leases in which it is the lessor for its rental property. Certain leases contain variable lease payments based upon changes in the Consumer Price Index (“CPI”). Billings for real estate taxes and other expenses are also considered to be variable lease payments. Certain leases contain options to renew or terminate the lease, and options for the lessee to purchase the rental property, all of which are predominately at the sole discretion of the lessee.

The following table summarizes the components of rental income included in the accompanying Consolidated Statements of Operations for the three and nine months ended September 30, 2023 and 2022.

11. Commitments and Contingencies

The Company is subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance subject to deductible requirements. Management believes that the ultimate settlement of these actions will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows.

The Company has letters of credit of approximately $3.3 million as of September 30, 2023 related to construction projects and certain other agreements.

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.

“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.

“SL 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 contractual monthly base rent as of September 30, 2023 (which differs from rent calculated in accordance with GAAP) multiplied by 12. If a tenant is in a free rent period as of September 30, 2023, the total annualized base rental revenue is calculated based on the first contractual monthly base rent amount multiplied by 12.

23

“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, weighted by square footage.

Overview

We are a REIT focused on the acquisition, ownership, and operation of industrial properties throughout the United States. We seek to (i) identify properties that offer relative value across all locations, industrial property types, and tenants through the principled application of our proprietary risk assessment model, (ii) operate our properties in an efficient, cost-effective manner, 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, 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 our acquisition activity, and (ii) internal growth, specifically our portfolio occupancy and rental rates. A variety of other factors, including those noted below, also may affect our future results of operations.

Outlook

The industrial real estate business is affected by the uncertainty regarding the current high inflationary, rising interest rate environment, disruption in the banking industry, and geopolitical tensions. These factors are key drivers of recent financial market volatility and concerns of a global recession. While U.S. gross domestic product (“GDP”) declined during the first two quarters of 2022, GDP increased more than 2% during the year ended June 30, 2023. Labor conditions also remained strong with a 3.8% unemployment rate as of September 2023. Going forward, the general consensus among economists is to expect an elevated risk of recession over the near term. While the macro-economic conditions continue to evolve and could result in tighter credit conditions, weakening tenant cash flows, and rising vacancy rates, we believe we will continue to benefit from having a well-diversified portfolio across various markets, tenant industries, and lease terms. Additionally, we believe that recent moves toward more regional supply chains and geopolitical tensions have accelerated a number of trends that positively impact U.S. industrial demand. However, given the current uncertainty and events discussed above, our acquisition activity slowed in 2022 and so far in 2023 has been significantly slower than our historical acquisition pace.

We believe that the current economic environment, while volatile, will provide us with an opportunity to demonstrate the diversification of our portfolio. Specifically, we believe our existing 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, strong liquidity, access to capital, and the fact that many of our competitors for the assets we purchase tend to be smaller local and regional investors who may be more heavily impacted by rising interest rates and lack of available capital.

Due to the COVID-19 pandemic, geopolitical uncertainty, and recent legislation supporting U.S. infrastructure, we expect acceleration in a number of industrial specific trends to support stronger long term demand, including:

the rise 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, 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 overall quality of the transportation infrastructure in the United States.
24


Our portfolio continues to benefit from historically low availability throughout the national industrial market. Demand has moderated in 2023 relative to recent peaks, but remains solid across a broad array of our markets and vacancy and availability rates remains low by historic standards. The weakening global and U.S. economic trends could be a notable headwind and may result in relatively less demand for space and higher vacancy. We believe that the diversification of our portfolio by market, tenant industry, and tenant credit will prove to be a strength in this environment.

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 and nine months ended September 30, 2023. Any rental concessions in such leases are accounted for on a straight-line basis over the term of the lease.

(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 and nine months ended September 30, 2023, leases commenced totaling 60,000 and 1,110,359 square feet related to Value Add assets and first generation leasing. These 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 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
25

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 8.1% of our total annualized base rental revenue will expire during the period from October 1, 2023 to September 30, 2024, 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 October 1, 2023 to September 30, 2024, thereby resulting in an increase in revenue from the same space.

The following table summarizes lease expirations for leases in place as of September 30, 2023, plus available space, for each of the ten calendar years beginning with 2023 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, 2022 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 considered to be 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 after December 31, 2021. On September 30, 2023, we owned 514 industrial buildings consisting of approximately 101.8 million square feet and representing approximately 91.0% of our total portfolio, that are considered our same store portfolio in the analysis below. Same store occupancy decreased approximately 1.0% to 98.0% as of September 30, 2023 compared to 99.0% as of September 30, 2022.

Comparison of the three months ended September 30, 2023 to the three months ended September 30, 2022

The following table summarizes selected operating information for our same store portfolio and our total portfolio for the three months ended September 30, 2023 and 2022 (dollars in thousands). This table includes a reconciliation from our same store portfolio to our total portfolio by also providing information for the three months ended September 30, 2023 and 2022 with respect to the buildings acquired and sold after December 31, 2021, Operating Portfolio buildings with expansions placed into service or transferred from the Value Add Portfolio to the Operating Portfolio after December 31, 2021, flex/office buildings, Value Add buildings, and buildings classified as held for sale.

Net Income

Net income for our total portfolio decreased by approximately $13.6 million, or 20.9%, to approximately $51.2 million for the three months ended September 30, 2023 compared to approximately $64.7 million for the three months ended September 30, 2022.

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 $9.0 million, or 6.0%, to approximately $160.0 million for the three months ended September 30, 2023 compared to approximately $151.0 million for the three months ended September 30, 2022.

Same store lease income increased by approximately $5.9 million, or 4.7%, to approximately $130.5 million for the three months ended September 30, 2023 compared to approximately $124.6 million for the three months ended September 30, 2022. The increase was primarily due to an increase in lease income of approximately $6.8 million from the execution of new leases and lease renewals with existing tenants. Additionally, there was an increase in same store lease income of approximately $0.8 million which was primarily attributable to management’s evaluation of operating leases to determine the probability of collecting substantially all of the lessee's remaining lease payments under the lease term. For those that are not probable of collection, we convert to the cash basis of accounting. Management determined one tenant should be converted from the cash basis of accounting back to the accrual basis of accounting, for which approximately $1.1 million of straight-line rental income was recognized. This was partially offset by certain other tenants converting from the accrual basis of accounting to the cash basis of accounting, for which approximately $0.3 million of straight-line rental income was reversed. These increases were partially offset by the reduction of base rent of approximately $1.7 million due to tenant vacancies.

Same store other billings increased by approximately $3.1 million, or 11.7%, to approximately $29.5 million for the three months ended September 30, 2023 compared to approximately $26.4 million for the three months ended September 30, 2022. The increase in other billings was primarily attributable to an increase of approximately $2.8 million in other expense reimbursements due to an increase in corresponding expenses and occupancy of previously vacant buildings. The increase was also attributable to an increase of approximately $0.3 million of real estate tax reimbursements due to occupancy of previously vacant buildings.

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 $3.1 million, or 11.0%, to approximately $30.8 million for the three months ended September 30, 2023 compared to approximately $27.8 million for the three months ended September 30, 2022. This increase was due to increases in repairs and maintenance, insurance, real estate tax, utility, and other expenses of approximately $1.1 million, $0.8 million, $0.4 million, $0.3 million, and $0.5 million, respectively.

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 December 31, 2021, we acquired 33 buildings consisting of approximately 5.0 million square feet (excluding seven buildings that were included in the Value Add Portfolio at September 30, 2023 or transferred from the Value Add Portfolio to the Operating Portfolio after December 31, 2021), and sold 17 buildings consisting of approximately 3.7 million square feet. For the three months ended September 30, 2023 and 2022, the buildings acquired after December 31, 2021 contributed approximately $7.6 million and $5.4 million to NOI, respectively. For the three months ended September 30, 2023 and September 30, 2022, the buildings sold after December 31, 2021 contributed approximately $0.4 million and $2.7 million
31

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 flex/office buildings, 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 December 31, 2021. Other NOI also includes termination, solar, and other income adjustments from buildings in our same store portfolio.

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

These buildings contributed approximately $6.1 million and $3.8 million to NOI for the three months ended September 30, 2023 and 2022, respectively. Additionally, there was approximately $1.6 million and $1.0 million of termination, solar, and other income adjustments from certain buildings in our same store portfolio for the three months ended September 30, 2023 and 2022, respectively.

Total Other Expenses

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

Total other expenses decreased approximately $1.1 million, or 1.3%, to approximately $81.6 million for the three months ended September 30, 2023 compared to approximately $82.7 million for the three months ended September 30, 2022. The decrease was primarily attributable to a decrease in loss on impairment of approximately $1.8 million, as there was no loss on impairment recognized during the three months ended September 30, 2023, compared to a loss on impairment recognized at one building during the three months ended September 30, 2022. The decrease was partially offset by an increase in depreciation and amortization expense of approximately $0.3 million due to an increase in the depreciable asset base from net acquisitions after September 30, 2022, as well as an increase in general and administrative expenses of approximately $0.2 million primarily due to increases in compensation and other payroll costs.

Total Other Income (Expense)

Total other income (expense) consists of interest and other income, interest expense, debt extinguishment and modification expenses, 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 $23.3 million, or 207.6%, to approximately $12.1 million total other expense for the three months ended September 30, 2023 compared to approximately $11.2 million total other income for the three months ended September 30, 2022. This decrease was primarily a result of a decrease in the gain on the sales of rental property, net of approximately $21.5 million. This decrease was also attributable to an increase in interest expense of approximately $2.6 million which was primarily attributable to a higher average credit facility balance and an increase in one-month Term Secured Overnight Financing Rate (“Term SOFR”) for the three months ended September 30, 2023, compared to the three months ended September 30, 2022. These decreases were partially offset by a decrease in debt and modification expenses of approximately $0.8 million, as there were no debt and modification expenses during the three months ended September 30, 2023.

Comparison of the nine months ended September 30, 2023 to the nine months ended September 30, 2022

The following table summarizes selected operating information for our same store portfolio and our total portfolio for the nine months ended September 30, 2023 and 2022 (dollars in thousands). This table includes a reconciliation from our same store portfolio to our total portfolio by also providing information for the nine months ended September 30, 2023 and 2022 with respect to the buildings acquired and disposed of and Operating Portfolio buildings with expansions placed into service or transferred from the Value Add Portfolio to the Operating Portfolio after December 31, 2021 and our flex/office buildings, Value Add Portfolio and buildings classified as held for sale.

Net Income

Net income for our total portfolio increased by $2.8 million, or 1.8%, to $154.6 million for the nine months ended September 30, 2023 compared to $151.8 million for the nine months ended September 30, 2022.

Same Store Total Operating Revenue

Same store total operating revenue consists primarily of rental income consisting of (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 is comprised of lease income and other billings as discussed below, increased by approximately $24.3 million, or 5.4%, to approximately $472.2 million for the nine months ended September 30, 2023 compared to approximately $447.9 million for the nine months ended September 30, 2022.

Same store lease income increased by approximately $16.4 million, or 4.4%, to approximately $386.7 million for the nine months ended September 30, 2023 compared to approximately $370.3 million for the nine months ended September 30, 2022. The increase was primarily due to an increase in rental income of approximately $21.6 million from the execution of new leases and lease renewals with existing tenants. This increase was partially offset by the reduction of base rent of approximately $4.4 million due to tenant vacancies, and a net increase in the amortization of net above market leases of approximately $0.3 million. Additionally, there was decrease in same store lease income of approximately $0.5 million which was primarily attributable to management’s evaluation of operating leases to determine the probability of collecting substantially all of the lessee's remaining lease payments under the lease term. For those that are not probable of collection, we convert to the cash basis of accounting. Management determined two tenants should be converted from the cash basis of accounting back to the accrual basis of accounting, for which approximately $1.4 million of straight-line rental income was recognized. This was offset by certain other tenants converting from the accrual basis of accounting to the cash basis of accounting, for which approximately $1.9 million of straight-line rental income was either reversed or was not recognized.

Same store other billings increased by approximately $7.9 million, or 10.2%, to approximately $85.5 million for the nine months ended September 30, 2023 compared to approximately $77.6 million for the nine months ended September 30, 2022. The increase was attributable to an increase of approximately $4.3 million in other expense reimbursements which was primarily due to an increase in corresponding expenses. The increase was also attributable to an increase of approximately $3.6 million of real estate tax reimbursements due to an increase in real estate taxes levied by the taxing authority for certain tenants for which we pay the real estate taxes on their behalf, changes to lease terms where we began paying the real estate taxes on behalf of tenants that had previously paid the taxes directly to the taxing authorities, and occupancy of previously vacant buildings.

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 operating expenses increased by approximately $7.3 million or 8.6% to approximately $91.8 million for the nine months ended September 30, 2023 compared to approximately $84.5 million for the nine months ended September 30, 2022. This increase was due to increases in repairs and maintenance, insurance, real estate tax, utility, and other expenses of approximately $2.3 million, $1.8 million, $1.7 million, $0.7 million, and $1.1 million, respectively. These increases were partially offset by a reduction of snow removal expense of approximately $0.3 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 December 31, 2021, we acquired 33 buildings consisting of approximately 5.0 million square feet (excluding seven buildings that were included in the Value Add Portfolio at September 30, 2023 or transferred from the Value Add Portfolio to the Operating Portfolio after December 31, 2021), and sold 17 buildings consisting of approximately 3.7 million
34

square feet. For the nine months ended September 30, 2023 and September 30, 2022, the buildings acquired after December 31, 2021 contributed approximately $19.8 million and $10.0 million to NOI, respectively. For the nine months ended September 30, 2023 and September 30, 2022, the buildings sold after December 31, 2021 contributed approximately $2.3 million and $8.8 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

Our other assets include our flex/office buildings, 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 December 31, 2021. Other NOI also includes termination, solar, and other income adjustments from buildings in our same store portfolio.

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

These buildings contributed approximately $16.0 million and $10.2 million to NOI for the nine months ended September 30, 2023 and September 30, 2022, respectively. Additionally, there was approximately $2.9 million and $3.6 million of termination, solar, and other income adjustments from certain buildings in our same store portfolio for the nine months ended September 30, 2023 and September 30, 2022, respectively.

Total Other Expenses

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

Total other expenses increased approximately $2.2 million, or 0.9%, to approximately $247.1 million for the nine months ended September 30, 2023 compared to approximately $244.9 million for the nine months ended September 30, 2022. The increase was attributable to an increase in other expenses of approximately $2.5 million, which was primarily attributable to the relinquishment of an acquisition deposit related to the termination of an acquisition contract in January 2023. Depreciation and amortization also increased approximately $1.1 million due to an increase in the depreciable asset base from net acquisitions after September 30, 2022, as well as an increase in general and administrative expenses of approximately $0.4 million primarily due to increases in compensation and other payroll costs. The increases were partially offset by a decrease in loss on impairment of approximately $1.8 million, as there was no loss on impairment recognized during the nine months ended September 30, 2023, compared to a loss on impairment recognized at one building during the nine months ended September 30, 2022.

Total Other Income (Expense)

Total other income (expense) consists of interest and other income, interest expense, debt extinguishment and modification expenses, 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 $20.3 million, or 4,668.9%, to a total other expense of approximately $19.8 million for the nine months ended September 30, 2023 compared to approximately $0.4 million total other income for the nine months ended September 30, 2022. This decrease was attributable to an increase in interest expense of approximately $12.9 million which was primarily attributable to the issuance of $400.0 million of unsecured notes on June 28, 2022, an additional $50.0 million of unsecured term loans on July 26, 2022, and an increase in one-month Term SOFR. This decrease was also attributable to a decrease in the gain on the sales of rental property, net of approximately $8.2 million. These decreases were partially offset by a decrease in debt and modification expenses of approximately $0.8 million, as there were no debt and modification expenses during the nine months ended September 30, 2023.

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.
35


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, land sales, 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 in accordance with the Nareit definition, and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should not be used as a measure of our liquidity, and is not indicative of funds available for our cash needs, including our ability to pay dividends.

The following table sets forth a reconciliation of our FFO attributable to common stockholders and unit holders for the periods presented to net income, the nearest GAAP equivalent.

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 and real estate taxes and insurance. 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.

Cash Flows

Comparison of the nine months ended September 30, 2023 to the nine months ended September 30, 2022

The following table summarizes our cash flows for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

 Nine months ended September 30,Change
Cash Flows (dollars in thousands)20232022$%

Net cash provided by (used in) financing activities$(81,112)$90,707 $(171,819)(189.4)%
 
Net cash provided by operating activities increased approximately $1.6 million to approximately $299.5 million for the nine months ended September 30, 2023 compared to approximately $297.9 million for the nine months ended September 30, 2022. The increase was primarily attributable to incremental operating cash flows from property acquisitions completed after September 30, 2022, and operating performance at existing properties. These increases were partially offset by the loss of cash flows from property dispositions completed after September 30, 2022 and fluctuations in working capital due to timing of payments and rental receipts.

Net cash used in investing activities decreased approximately $164.2 million to approximately $233.2 million for the nine months ended September 30, 2023 compared to approximately $397.3 million for the nine months ended September 30, 2022. The decrease was primarily attributable to the acquisition of 14 buildings and land parcels for a total cash consideration of approximately $254.5 million during the nine months ended September 30, 2023, compared to the acquisition of 25 buildings and land parcels for a total cash consideration of approximately $464.6 million for the nine months ended September 30, 2022. This decrease was partially offset by a decrease in proceeds from sales of rental property, net of approximately $33.7 million during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022, as well as an increase of approximately $12.7 million in cash paid for the additions of land and buildings and improvements related to development and other capital expenditures during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

Net cash provided by (used in) financing activities decreased approximately $171.8 million to approximately $81.1 million net cash used in financing activities for the nine months ended September 30, 2023 compared to approximately $90.7 million net cash provided by financing activities for the nine months ended September 30, 2022. This decrease was primarily attributable to the funding of the $400.0 million unsecured notes on June 28, 2022 and $50.0 million unsecured term loan on July 26, 2022, that did not occur during the nine months ended September 30, 2023, as well as the redemption of $100.0 million of unsecured notes on January 5, 2023 that did not occur during the nine months ended September 30, 2022. These decreases were partially offset by an increase in net borrowings of approximately $310.0 million under our unsecured credit facility and an increase in proceeds from sales of common stock, net of approximately $14.9 million during the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022. Additionally, we paid in full a mortgage note in the amount of approximately $46.6 million during the nine months ended September 30, 2022 that did not occur during the nine months ended September 30, 2023.

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 is our principal source 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 (common and preferred equity and debt securities) 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 the Operating Partnership.

As of September 30, 2023, we had total immediate liquidity of approximately $682.6 million, comprised of $10.9 million of cash and cash equivalents and $671.7 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 the 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.

(1)Interest rate as of September 30, 2023. At September 30, 2023, the one-month Term SOFR was 5.31899%. The current interest rate is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums or discounts. The spread over the applicable rate for our unsecured credit facility and unsecured term loans is based on our debt rating and leverage ratio, as defined in the respective loan agreements.
(2)Our unsecured credit facility has a stated interest rate of one-month Term SOFR plus a 0.10% adjustment and a spread of 0.775%, less a sustainability-related interest rate adjustment of 0.02%. Our unsecured term loans have a stated interest rate of one-month Term SOFR plus a 0.10% adjustment and a spread of 0.85%, less a sustainability-related interest rate adjustment of 0.02%. As of September 30, 2023, one-month Term SOFR for the Unsecured Term Loans A, F, G, H, and I was swapped to a fixed rate of 1.31%, 2.11%, 0.95%, 2.90%, and 2.66%, respectively (which includes the 0.10% adjustment). One-month Term SOFR for the Unsecured Term Loan H will be swapped to a fixed rate of 2.50% effective January 12, 2024.
(3)Prepayment terms consist of (i) pre-payable with no penalty; (ii) pre-payable with penalty; (iii) pre-payable without penalty three months prior to the maturity date.
(4)The capacity of our unsecured credit facility is $1.0 billion. The initial maturity date is October 24, 2025, or such later date which may be extended pursuant to two six-month extension options exercisable by us in our discretion upon advance written notice. Exercise of each six-month option is subject to the following conditions: (i) absence of a default immediately before the extension and immediately after giving effect to the extension, (ii) accuracy of representations and warranties as of the extension date (both immediately before and after the extension), as if made on the extension date, and (iii) payment of a fee. Neither extension option is subject to lender consent, assuming proper notice and satisfaction of the conditions. We are required to pay a facility fee on the aggregate commitment amount (currently $1.0 billion) at a rate per annum of 0.1% to 0.3%, depending on our debt rating, as defined in the credit agreement. The facility fee is due and payable quarterly.
(5)The weighted average interest rate was calculated using the fixed interest rate swapped on the notional amount of $1,025.0 million of debt and is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums or discounts.

The aggregate undrawn nominal commitments on our unsecured credit facility and unsecured term loans as of September 30, 2023 was approximately $671.7 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 notes are subject to ongoing compliance with a number of financial and other covenants. As of September 30, 2023, we were in compliance with the applicable financial covenants.

On January 5, 2023, we redeemed in full at maturity the $100.0 million in aggregate principal amount of the Series F Unsecured Notes with a fixed interest rate of 3.98%.

On January 19, 2023, the sustainability-related interest rate adjustment for our Unsecured Term Loan H and Unsecured Term Loan I went into effect because of the improvement in our 2022 public disclosure assessment score from the Global Real Estate Sustainability Benchmark (GRESB), as compared to our 2021 score. The interest rate adjustment, a 0.02% interest rate reduction for each instrument, will end on June 29, 2024, in accordance with the respective loan agreements.

(1)“Net Debt” means amounts outstanding under our unsecured credit facility, unsecured term loans, unsecured notes, and mortgage notes, 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

Preferred Stock

We are authorized to issue up to 20,000,000 shares of preferred stock, par value $0.01 per share. As of September 30, 2023 and December 31, 2022, there were no shares of preferred stock issued or outstanding.

Common Stock

We are authorized to issue up to 300,000,000 shares of common stock, par value $0.01 per share.

The following table summarizes our at-the-market (“ATM”) common stock offering program as of September 30, 2023. 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 under the ATM common stock offering program during the three months ended September 30, 2023.

In addition, on May 5, 2023, we sold 725,698 shares on a forward basis under the ATM common stock offering program at a sale price of $35.0458 per share (an aggregate of approximately $25.4 million in gross sale price), or $34.6953 per share net of commissions. We did not initially receive any proceeds from the sale of shares on a forward basis. On July 27, 2023, we physically settled in full the forward sales agreements by issuing 725,698 shares of common stock for net proceeds of approximately $25.2 million, or $34.7714 per share.

On June 16, 2023, we also sold 992,295 shares on a forward basis under the ATM common stock offering program at a weighted average sale price of $36.5319 per share (an aggregate of approximately $36.3 million in gross sale price), or $36.1820 per share net of commissions. We did not initially receive any proceeds from the sale of shares on a forward basis. On July 27, 2023, we physically settled in full the forward sales agreements by issuing 992,295 shares of common stock for net proceeds of approximately $35.9 million, or $36.2046 per share.

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 September 30, 2023, we owned approximately 97.8% 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 2.2%.

Interest Rate Risk

We use interest rate swaps to fix the rate of our variable rate debt. As of September 30, 2023, 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 September 30, 2023, we had 21 interest rate swaps outstanding that were in an asset position of approximately $76.9 million, including any adjustment for nonperformance risk related to these agreements.

As of September 30, 2023, we had approximately $1,350.0 million of variable rate debt. As of September 30, 2023, all of our outstanding variable rate debt, with the exception of our unsecured credit facility, was fixed with interest rate swaps through 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 September 30, 2023, we had letters of credit related to development projects and certain other agreements of approximately $3.3 million. As of September 30, 2023, we had no other material off-balance sheet arrangements.

41

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 September 30, 2023, we had $1,350.0 million of variable rate debt outstanding. As of September 30, 2023, all of our outstanding variable rate debt, with the exception of our unsecured credit facility which had a balance of $325.0 million, was fixed with interest rate swaps through 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 $325.0 million on our unsecured credit facility for the nine months ended September 30, 2023, our interest expense would have increased by approximately $2.4 million for the nine months ended September 30, 2023.

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by SEC Rule 13a-15(b), we have evaluated, under the supervision of and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act, as of September 30, 2023. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures for the periods covered by this report were effective to provide reasonable assurance that information required to be disclosed by our Company in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Controls

There was no change to our internal control over financial reporting during the quarter ended September 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. Other Information

Item 1.  Legal Proceedings
From time to time, we are a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. We are not currently a party, as plaintiff or defendant, to any legal proceedings that, individually or in the aggregate, would be expected to have a material effect on our business, financial condition or results of operations if determined adversely to our company.

Item 1A.  Risk Factors
Other than the following, there have been no material changes from the risk factors disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 15, 2023.

Recent macroeconomic trends, including inflation and rising interest rates, and adverse developments affecting the financial services industry may adversely affect our business, financial condition and results of operations.

During the year ended December 31, 2022, inflation in the United States accelerated and is currently expected to continue at an elevated level in the near-term. Beginning in 2022, in an effort to combat inflation and restore price stability, the Federal Reserve significantly raised its benchmark federal funds rate, which led to increases in interest rates in the credit markets. The Federal Reserve may continue to raise the federal funds rate, which will likely lead to higher interest rates in the credit markets and the possibility of slowing economic growth and/or a recession. Additionally, U.S. government policies implemented to address inflation, including actions by the Federal Reserve to increase interest rates, could negatively impact consumer spending, our tenants’ businesses, and/or future demand for industrial space.

Rising inflation could also have an adverse impact on our financing costs (either through near-term borrowings on our variable rate debt, including our unsecured credit facility, or refinancing of existing debt at higher interest rates), and general and administrative expenses and property operating expenses, as these costs could increase at a rate higher than our rental and other revenue. To the extent our exposure to increases in interest rates is not eliminated through interest rate swaps or other protection agreements, such increases may also result in higher debt service costs, which will adversely affect our cash flows. Historically, during periods of increasing interest rates, real estate valuations have generally decreased due to rising capitalization rates, which tend to move directionally with interest rates. Consequently, prolonged periods of higher interest rates may negatively impact the valuation of our real estate assets and could result in the decline of the market price of our common stock, which may adversely impact our ability and willingness to raise equity capital on favorable terms, including through our at-the-market (“ATM”) common stock offering program. Although the extent of any prolonged periods of higher interest rates remains unknown at this time, negative impacts to our cost of capital may adversely affect our future business plans and growth, at least in the near term.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank was closed by the California Department of Financial Protection and Innovation, which appointed the FDIC as receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership. In addition, if any parties with whom we conduct business are unable to access funds pursuant to such instruments or lending arrangements with such a financial institution, such parties’ ability to pay their obligations to us or to enter into new commercial arrangements requiring additional payments to us could be adversely affected. Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources and other credit arrangements in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial services industry or economy in general. These factors could include, among others, events such as liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets, or concerns or negative expectations about the prospects for companies in the financial services industry.

If debt is unavailable at reasonable rates, we may not be able to finance acquisitions or refinance our existing debt.

If debt is unavailable at reasonable rates, we may not be able to finance acquisitions or refinance existing debt when the loans come due on favorable terms, or at all. Most of our financing arrangements require us to make a lump-sum or “balloon” payment at maturity. Our ability to make a payment at maturity is uncertain and, in the event that we do not have sufficient
43

funds, we will need to refinance this debt. If interest rates are higher when we refinance such debt, our net income, cash flow, and, consequently, our cash available for distribution to stockholders could be reduced. If the credit environment is constrained at the time a payment is due, we may not be able to refinance the existing debt on acceptable terms and may be forced to choose from a number of unfavorable options, including accepting unfavorable financing terms, selling properties on disadvantageous terms or defaulting and permitting the lender to foreclose.

In addition, adverse developments affecting the financial services industry or investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our financial or other obligations or reduce our net income and cash available for distribution to stockholders.

As of September 30, 2023, one-month Term SOFR for the Unsecured Term Loans A, F, G, H, and I was swapped to a fixed rate of 1.31%, 2.11%, 0.95%, 2.90%, and 2.66%, respectively (which includes the 0.10% adjustment). One-month Term SOFR for the Unsecured Term Loan H will be swapped to a fixed rate of 2.50% effective January 12, 2024.
(3)Prepayment terms consist of (i) pre-payable with no penalty; (ii) pre-payable with penalty; (iii) pre-payable without penalty three months prior to the maturity date.
(4)The capacity of the unsecured credit facility is $1.0 billion. Deferred financing fees and debt issuance costs, net of accumulated amortization related to the unsecured credit facility of approximately $3.8 million and $5.2 million are included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets as of September 30, 2023 and December 31, 2022, respectively. The initial maturity date is October 24, 2025, or such later date which may be extended pursuant to two six-month extension options exercisable by the Company in its discretion upon advance written notice. Exercise of each six-month option is subject to the following conditions: (i) absence of a default immediately before the extension and immediately after
giving effect to the extension; (ii) accuracy of representations and warranties as of the extension date (both immediately before and after the extension), as if made on the extension date; and (iii) payment of a fee. Neither extension option is subject to lender consent, assuming proper notice and satisfaction of the conditions. The Company is required to pay a facility fee on the aggregate commitment amount (currently $1.0 billion) at a rate per annum of 0.1% to 0.3%, depending on our debt rating, as defined in the credit agreement. The facility fee is due and payable quarterly.
(5)The weighted average interest rate was calculated using the fixed interest rate swapped on the notional amount of $1,025.0 million of debt and is not adjusted to include the amortization of deferred financing fees or debt issuance costs incurred in obtaining debt or any unamortized fair market value premiums or discounts.

The aggregate undrawn nominal commitment on the unsecured credit facility as of September 30, 2023 was approximately $671.7 million, including issued letters of credit. The Company’s actual borrowing capacity at any given point in time may be restricted to a maximum amount based on the Company’s debt covenant compliance. Total accrued interest for the Company’s indebtedness was approximately $17.2 million and $13.1 million as of September 30, 2023 and December 31, 2022, respectively, and is included in accounts payable, accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets.

The following table summarizes the costs included in interest expense related to the Company’s debt arrangements on the accompanying Consolidated Statement of Operations for the three and nine months ended September 30, 2023 and 2022.

Debt Activity

On January 5, 2023, the Company redeemed in full at maturity the $100.0 million in aggregate principal amount of the Series F Unsecured Notes with a fixed interest rate of 3.98%.

On January 19, 2023, the sustainability-related interest rate adjustment for the Unsecured Term Loan H and Unsecured Term Loan I went into effect because of the improvement in the Company’s 2022 public disclosure assessment score from the Global Real Estate Sustainability Benchmark (GRESB), as compared to the 2021 score. The interest rate adjustment, a 0.02% interest rate reduction for each instrument, will end on June 29, 2024, in accordance with the respective loan agreements.

Financial Covenant Considerations

The Company was in compliance with all such applicable restrictions and financial and other covenants as of September 30, 2023 and December 31, 2022 related to its unsecured credit facility, unsecured term loans, unsecured notes, and mortgage notes. The real estate net book value of the properties that are collateral for the Company’s debt arrangements was approximately $14.8 million and $14.8 million at September 30, 2023 and December 31, 2022, respectively, and is limited to senior, property-level secured debt financing arrangements.

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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivative Financial Instruments 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 September 30, 2023, the Company had 21 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 components to effectively fixed interest rates, and the Company has concluded that each of the hedging relationships are highly effective. The following table summarizes the fair value of the interest rate swaps as of September 30, 2023 and December 31, 2022.

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 (loss) 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 $35.9 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 Company’s derivatives in the consolidated financial statements for the three and nine months ended September 30, 2023 and 2022.

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 September 30, 2023, the Company had not breached the provisions of these agreements and had not posted any collateral related to these agreements.

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 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.

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 September 30, 2023 and December 31, 2022, 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 September 30, 2023 and December 31, 2022. There were no financial instruments in a liability position at September 30, 2023 and December 31, 2022.

LTIP Units

The Company granted LTIP units under the 2011 Plan on January 11, 2023 to non-employee, independent directors, which will vest on January 1, 2024, subject to the recipient’s continued service. The Company granted LTIP units under the 2011 Plan on January 11, 2023 to certain executive officers and senior employees of the Company, which will vest in equal installments on a quarterly basis over four years, with the first vesting date having been March 31, 2023, subject to the recipient’s continued employment. Refer to Note 8 for a discussion of the LTIP units granted on January 11, 2023 pursuant to the 2020 performance units.

On March 13, 2023, the Company executed an employment agreement with Steven T. Kimball to serve as the Company's Executive Vice President of Real Estate Operations, effective March 31, 2023. On March 31, 2023, pursuant to the 2011 Plan, the Company awarded Mr. Kimball an initial LTIP unit grant equal in value to approximately $0.6 million, which equated to 19,345 LTIP units, which will vest in equal installments on a quarterly basis over four years, with the first vesting date having been March 31, 2023, subject to Mr. Kimball’s continued employment.

The fair value of the LTIP units as of the grant date was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the LTIP units are based on Level 3 inputs and non-recurring fair value measurements. The following table summarizes the assumptions used in valuing such LTIP units granted during the nine months ended September 30, 2023 (excluding the LTIP units granted pursuant to the 2020 performance units discussed in Note 8).

On January 11, 2023, the compensation committee of the board of directors approved and the Company granted performance units under the 2011 Plan to the executive officers and certain key employees of the Company. The terms of the performance units granted on January 11, 2023 are substantially the same as the terms of the performance units granted in January 2022, 2021, and 2020, except that the measuring period commenced on January 1, 2023 and ends on December 31, 2025, and the size-based peer group was eliminated. The target amount of the performance units granted on January 11, 2023 is nominally allocated as follows: (i) 50% to the Company’s total stockholder return (“TSR”) compared to the TSR of an industry peer group; and (ii) 50% to the Company’s TSR compared to the TSR of the companies in the MSCI US REIT Index.

On March 31, 2023, in connection with the execution of the employment agreement discussed in Note 7, the Company granted Mr. Kimball performance units under the 2011 Plan with a target grant date fair value equal to approximately $0.6 million. The terms and measuring period of the performance units granted to Mr. Kimball are the same as the performance units granted on January 11, 2023.

On April 25, 2023, the Company’s stockholders approved an amendment (the “Amendment”) to the 2011 Plan which increased the total number of shares of common stock of the Company authorized and reserved for issuance under the 2011 Plan by 3,500,000 shares to an aggregate of 10,142,461 shares of common stock, subject to certain adjustments as described in the 2011 Plan. The Amendment also extended the expiration date of the 2011 Plan from April 30, 2028 to April 24, 2033.
The fair value of the performance units as of the grant date was determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The fair value of the performance units is based on Level 3 inputs and non-recurring fair value measurements. The performance unit equity compensation expense is recognized ratably from the grant date into earnings over the vesting period. The following table summarizes the assumptions used in valuing the performance units granted during the nine months ended September 30, 2023.

The expected dividend yield is based on the Company’s average historical dividend yield and the dividend yield as of the valuation date for each award. The risk-free interest rate is based on U.S. Treasury note yields matching the time period of the grant date to the end of the measuring period.

On December 31, 2022, the measuring period for the 2020 performance units concluded, and it was determined that the Company’s TSR exceeded the threshold percentage and return hurdle. The following table summarizes the issuances of LTIP units and shares of common stock approved by the compensation committee of the board of directors and issued upon the settlement of the 2020 performance units at the conclusion of the applicable measuring period during the nine months ended September 30, 2023.
