Overview

The Company owns and operates properties that facilitate the delivery of healthcare services in primarily outpatient settings. To execute its strategy, the Company engages in a broad spectrum of integrated services including leasing, management, acquisition, financing, development and redevelopment of such properties. The Company seeks to generate stable, growing income and lower the long-term risk profile of its portfolio of properties by focusing on facilities primarily located on or near the campuses of acute care hospitals associated with leading health systems. The Company seeks to reduce financial and operational risk by owning properties in high-growth markets with a broad tenant mix that includes over 30 physician specialties, as well as surgery, imaging, cancer, and diagnostic centers.

As described in the Explanatory Note above and elsewhere in this report, on July 20, 2022, Legacy HR and Legacy HTA completed a merger between the companies in which Legacy HR merged with and into a wholly-owned subsidiary of Legacy HTA, with Legacy HR continuing as the surviving entity and a wholly-owned subsidiary of Legacy HTA. Immediately following the Merger, Legacy HTA changed its name to “Healthcare Realty Trust Incorporated.” For accounting purposes, the Merger was treated as a “reverse acquisition” in which Legacy HR was considered the acquirer. Accordingly, the information discussed in this section reflects, for periods prior to the closing of the Merger, the financial condition and results of operations of Legacy HR, and for periods from the closing of the Merger, that of the Company.

This section is organized into the following sections:

•Liquidity and Capital Resources;

•Trends and Matters Impacting Operating Results;

•Non-GAAP Financial Measures and Key Performance Indicators; and

•Application of Critical Accounting Policies to Accounting Estimates.

Liquidity and Capital Resources

The Company monitors its liquidity and capital resources and considers several indicators in its assessment of capital markets for financing acquisitions and other operating activities. The Company considers, among other factors, its leverage ratios and lending covenants, dividend payout percentages, interest rates, underlying treasury rates, debt market spreads and cost of equity capital to compare its operations to its peers and to help identify areas in which the Company may need to focus its attention.

Sources and Uses of Cash

The Company's revenues are derived from its real estate property portfolio based on contractual arrangements with its tenants. These sources of revenue represent the Company's primary source of liquidity to fund its dividends and its operating expenses, including interest incurred on debt, principal payments on debt, general and administrative costs, capital expenditures and other expenses incurred in connection with managing its existing portfolio and investing in additional properties. To the extent additional investments are not funded by these sources, the Company will fund its investment activity generally through equity or debt issuances either in the public or private markets, property dispositions or through proceeds from the Unsecured Credit Facility.

The Company expects to continue to meet its liquidity needs, including capital for additional investments, tenant improvement allowances, operating and finance lease payments, paying dividends, and funding debt service, through cash on hand, cash flows from operations and the cash flow sources addressed above. See Note 4 to the Consolidated Financial Statements for additional discussion of operating and financing lease payment obligations. See "Trends and Matters Impacting Operating Results" for additional information regarding the Company's sources and uses of cash.

The Company also had unencumbered real estate assets with a gross book value of approximately$13.2 billionat December 31, 2023, of which a portion could serve as collateral for secured mortgage financing. The Company believes that its liquidity and sources of capital are adequate to satisfy its cash requirements. The Company cannot, however, be certain that these sources of funds will be available at a time and upon terms acceptable to the Company in sufficient amounts to meet its liquidity needs.

The Company has exposure to variable interest rates and its common stock price is impacted by the volatility in the stock markets. However, the Company’s leases, which provide its main source of income and cash flow, have terms of approximately one to 20 years and have lease rates that generally increase on an annual basis at fixed rates or based on consumer price indices.

Operating Activities

Cash flows provided by operating activities for the two years ended December 31, 2023 and 2022 were $499.8 million and $272.7 million, respectively. Several items impact cash flows from operating activities including, but not limited to, cash generated from property operations, merger-related costs, interest payments and the timing related to the payment of invoices and other expenses and receipt of tenant rent.

The Company may, from time to time, sell properties and redeploy cash from property sales into new investments. To the extent revenues related to the properties being sold exceed income from these new investments, the Company's consolidated results of operations and cash flows could be adversely affected.

See "Trends and Matters Impacting Operating Results" for additional information regarding the Company's operating activities.

An extension fee of $0.4 million (0.125% of the committed funds) was paid and will be amortized over the extension term.

Interest Rate Swaps

As of December 31, 2023, the Company had outstanding interest rate derivatives totaling approximately$1.3 billion to hedge one-month SOFR. The following details the amount and rate of each swap as of such date (dollars in thousands):

2023 Interest Rate Swap Activity

On February 16, 2023, the Company entered into a swap transaction with a notional amount of $50.0 million and a fixed rate of 4.16%. The swap agreement has an effective date of March 1, 2023 and a termination date of June 1, 2026.

On March 28, 2023, the Company entered into a swap transaction with a notional amount of $100.0 million and a fixed rate of 3.67%. The swap agreement has an effective date of April 3, 2023 and a termination date of June 1, 2026.

On October 19, 2023, the Company entered into two swap transactions totaling $100.0 million. The notional amounts were $50.0 million each with fixed rates of 4.71% and 4.67%.

3 Debt instruments assumed as part of the Merger with Legacy HTA on July 20, 2022. The amounts shown represent fair value adjustments.

4 As of December 31, 2023, the Company had no outstanding borrowings under the Unsecured Credit Facility with a remaining borrowing capacity of $1.5 billion.

Debt Covenant Information

The Company’s various debt agreements contain certain representations, warranties, and financial and other covenants customary in such debt agreements. Among other things, these provisions require the Company to maintain certain financial ratios and impose certain limits on the Company’s ability to incur indebtedness and create liens or encumbrances. As of December 31, 2023, the Company was in compliance with the financial covenant provisions under all of its various debt instruments.

As of December 31, 2023, 99.5% of the Company’s principal balances were due after 2024, including extension options. Also, as of December 31, 2023, the Company's incurrence of total debt as defined in the senior notes [debt divided by (total assets less intangibles and accounts receivable)] was approximately 37.5% (cannot be greater than 60%) and debt service coverage [interest expense divided by (net income plus interest expense, taxes, depreciation and amortization, gains and impairments)] was approximately 3.2 times (cannot be less than 1.5 times).

The Company plans to manage its capital structure to maintain compliance with its debt covenants consistent with its current profile. Downgrades in ratings by the rating agencies could have a material adverse impact on the Company’s cost and availability of capital, which could in turn have a material adverse impact on consolidated results of operations, liquidity and/or financial condition.

Trends and Matters Impacting Operating Results

Management monitors factors and trends important to the Company and the REIT industry in order to gauge their potential impact on the operations of the Company. Discussed below are some of the factors and trends that management believes may impact the future operations of the Company.

Economic and Market Conditions

Rising interest rates and increased volatility in the capital markets have increased the Company’s cost and availability of debt and equity capital. Limited availability and increases in the cost of capital could adversely impact the Company’s ability to finance operations and acquire and develop properties. To the extent the Company’s tenants experience increased costs or financing difficulties due to the economic and market conditions, they may be unable or unwilling to make payments or perform their obligations when due. Additionally, increased interest rates may also result in less liquid property markets, limiting the Company’s ability to sell existing assets or obtain joint venture capital.

The Company reviews goodwill for impairment annually as of December 31 of each year or whenever events or changes in circumstances indicate that an impairment may exist. Given volatility in its stock price, the Company performed a quantitative assessment, and the fair value of the Company’s single reporting unit was estimated using a combination of discounted cash flow models and earnings multiples techniques. The determination of fair value using the discounted cash flow model technique requires the use of estimates and assumptions related to revenue and expense growth rates, capitalization rates, discount rates, capital expenditures and working capital levels. The determination of fair value using the earnings multiples technique requires assumptions to be made in relation to maintainable earnings and earnings multipliers. These forecasts and assumptions are highly subjective, and while we believe our assumptions are reasonable, changes in these assumptions may have a material impact on our financial results. Although the quantitative assessment indicated goodwill was not impaired as of December 31, 2023, given the results of our quantitative assessment, the Company is at risk for future goodwill impairment because it is reasonably possible that, among other factors, continual stock price volatility and downward pressure on the Company's market capitalization could have a material impact on one or more of the estimates and assumptions used to evaluate goodwill.

Acquisitions and Dispositions

In 2023, the Company acquired two medical office buildings. The total purchase price of the acquisitions was $43.0 million and the weighted average capitalization rate for these investments was 6.5%.

The Company disposed of 39 properties in 2023 for sales prices totaling $787.0 million, including a regional corporate office and one property contributed into a joint venture in which the Company maintains a non-controlling interest. These transactions yielded net cash proceeds of $687.6 million, net of $36.9 million of closing costs and related adjustments, $58.7 million in Company financed notes and $3.8 million of retained joint venture interests. The weighted average capitalization rate for these properties was 6.5%. The Company calculates the capitalization rate for dispositions as the in-place cash net operating income divided by the sales price.

See the Company's discussion of its 2023 acquisition and disposition activity in Note 5 to the Consolidated Financial Statements.

Development and Redevelopment Activity

The table below details the Company’s activity related to its active development and redevelopment projects as of December 31, 2023. The information included in the table below represents management’s estimates and expectations at December 31, 2023, which are subject to change. The Company’s disclosures regarding certain projections or estimates may not reflect actual results.

1 This project is funded through a construction note receivable.

The Company funded an additional $22.6 million related to ongoing tenant improvements at previously completed projects.

The Company is in the planning stages with several health systems and developers regarding new development and redevelopment opportunities and one or more could begin in 2024. Total costs to develop or redevelop a typical medical office building can vary depending on the scope of the project, market rental terms, parking configuration, building amenities, asset type and geographic location.

The Company’s disclosures regarding certain estimates or projections may not be indicative of actual results.

Security Deposits and Letters of Credit

As of December 31, 2023, the Company held approximately $38.5 million in letters of credit and security deposits for the benefit of the Company in the event the obligated tenant fails to perform under the terms of its respective lease. Generally, the Company may, at its discretion and upon notification to the tenant, draw upon these instruments if there are any defaults under the leases.

Expiring Leases

The Company expects that approximately 15% to 20% of the leases in its portfolio will expire each year. In-place leases have a weighted average lease term of 8.5 years and a weighted average remaining lease term of 4.2 years. Demand for well-located real estate with complementary practice types and services remains consistent, and the Company's 2023 quarterly tenant retention statistics ranged from 74% to 79%. In 2024, the Company has 1,546 leases totaling 5.0 million square feet in its multi-tenant portfolio that are scheduled to expire. Of those leases, 74% are in on-campus buildings, which, in our experience, tend to have high tenant retention rates between 75% to 90%. See additional information regarding expiring single-tenant leases under the heading "Single-Tenant Leases" below.

The Company continues to emphasize its contractual rent increases for in-place leases. As of December 31, 2023 and 2022, the Company's contractual rental rate growth averaged 2.82% and 2.77%, respectively, for in-place leases. In addition, the Company continued to see strong quarterly weighted average rental rate growth for renewing leases ("cash leasing spread") and expects the majority of its renewal rates to increase between 3.0% and 4.0%. In 2023, cash leasing spreads averaged 2.6%.

In a further effort to maximize revenue growth and reduce its exposure to key expenses such as taxes and utilities, the Company carefully manages its balance of lease types. Gross leases, wherein the Company has full exposure to all operating expenses, comprise 8% of its lease portfolio. Modified gross or base year leases, in which the Company and tenant both pay a share of operating expenses, comprise 28% of the Company's leased portfolio. Net leases, in which tenants pay substantially all operating expenses, total 59% of the leased portfolio. Absolute net leases, in which tenants pay substantially all the building's operating and capital expenses, comprise 5%.

Capital Expenditures

Capital expenditures are long-term investments made to maintain and improve the physical and aesthetic attributes of the Company's owned properties. Examples of such improvements include, but are not limited to, material changes to, or the full replacement of, major building systems (exterior facade, building structure, roofs, elevators, mechanical systems, electrical systems, energy management systems, upgrades to existing systems for improved efficiency) and common area improvements (furniture, signage and artwork, bathroom fixtures and finishes, exterior landscaping, parking lots or garages). These additions are capitalized into the gross investment of a property and then depreciated over their estimated useful lives, typically ranging from 7 to 20 years. Capital expenditures specifically do not include recurring maintenance expenses, whether direct or indirect, related to the upkeep and maintenance of major building systems or common area improvements. Capital expenditures also do not include improvements related to a specific tenant suite, unless the improvement is part of a major building system or common area improvement.

The Company invested $47.7 million, or $1.24 per square foot, in capital expenditures in 2023 and $48.9 million, or $1.21 per square foot, in capital expenditures in 2022. As a percentage of cash net operating income, 2023 and 2022 capital expenditures were 5.8% and 8.5%, respectively. For a reconciliation of cash net operating income, see "Same Store Cash NOI" in the "Non-GAAP Financial Measures and Key Performance Indicators" section as part of Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations included in Part II of this report.

Tenant Improvements

The Company may invest in tenant improvements for the purpose of refurbishing or renovating tenant space. The Company categorizes these expenditures into first and second generation tenant improvements. As of December 31, 2023, the Company had commitments of approximately $222.4 million that are expected to be spent on tenant improvements throughout the portfolio, excluding development properties currently under construction.

First Generation Tenant Improvements & Planned Capital Expenditures for Acquisitions

First generation tenant improvements and planned capital expenditures for acquisition spending totaled $38.7 million and $46.4 million for the years ended December 31, 2023 and 2022, respectively. First generation tenant improvements include build out costs related to suite space in shell condition. Planned capital expenditures for acquisitions include expected near-term fundings that were contemplated as part of the acquisition.

Second Generation Tenant Improvements

Second generation tenant improvements spending totaled $63.5 million in 2023, or 7.7% of total cash net operating income. In 2022, this spending totaled $33.6 million, or 5.8% of total cash net operating income.

If the cost of a tenant improvement project exceeds a tenant improvement allowance, the Company generally offers the tenant the option to finance the excess over the lease term with interest or to reimburse the overage to the Company in a lump sum. In either case, such overages are amortized by the Company as rental income over the term of the lease. Interest earned on tenant overages is included in other operating income in the Company's Consolidated Statements of Operations. The first and second generation tenant overage amount amortized to rent, including interest, totaled approximately $8.4 million in 2023, $7.5 million in 2022, and $5.9 million in 2021.

Second generation, multi-tenant tenant improvement commitments in 2023 for renewals averaged $1.78 per square foot per lease year, ranging quarterly from $1.64 to $1.89. In 2022, these commitments averaged $1.76 per square foot per lease year, ranging quarterly from $1.46 to $1.90. In 2021, these commitments averaged $1.53 per square foot per lease year, ranging quarterly from $1.27 to $1.87.

Second generation, multi-tenant tenant improvement commitments in 2023 for new leases averaged $5.69 per square foot per lease year, ranging quarterly from $4.44 to $7.11. In 2022, these commitments averaged $5.74 per square foot per lease year, ranging quarterly from $4.84 to $7.07. In 2021, these commitments averaged $5.39 per square foot per lease year, ranging quarterly from $4.74 to $5.96.

Leasing Commissions

In certain markets, the Company may pay leasing commissions to real estate brokers who represent either the Company or prospective tenants, with commissions generally equating to 4% to 6% of the gross lease value for new leases and 2% to 4% of the gross lease value for renewal leases. In addition, the Company pays its leasing employees incentive compensation when leases are executed that meet certain leasing thresholds. External leasing commissions are amortized to property operating expense, and internal leasing costs are amortized to general and administrative expense in the Company's Consolidated Statements of Operations. In 2023, the Company paid leasing commissions of approximately $35.9 million, or $0.93 per square foot. In 2022, the Company paid leasing commissions of approximately $22.9 million, or $0.57 per square foot. As a percentage of total cash net operating income, leasing commissions paid for 2023 and 2022 were 4.3% and 4.0%, respectively. The amount of leasing commissions amortized over the term of the applicable leases totaled $13.8 million, $11.0 million and $9.0 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Rent Abatements

Rent abatements, which generally take the form of deferred rent, are sometimes used to help induce a potential tenant to lease space in the Company's properties. Such abatements, when made, are amortized by the Company on a straight-line basis against rental income over the lease term. Rent abatements for 2023 totaled approximately $14.3 million, or $0.37 per square foot. Rent abatements for 2022 totaled approximately $14.8 million, or $0.37 per square foot. Rent abatements for 2021 totaled approximately $4.6 million, or $0.27 per square foot.

Single-Tenant Leases

As of December 31, 2023, the Company had a total of 125 single-tenant buildings, with a weighted average lease term of 11.4 years and a weighted average remaining lease term of 5.2 years.

Twenty-one single-tenant buildings have leases that expire in 2024. Eleven of these leases have been renewed. The Company is in negotiations with eight of the tenants and expects the leases to be renewed or the building to be immediately backfilled. The Company expects the tenants of two of these single-tenant buildings to vacate the buildings upon lease expiration. One of these buildings is part of a planned redevelopment and the other is expected to be leased or sold. The expected lost revenue from these expirations in 2024 is $3.8 million.

Operating Leases

As of December 31, 2023, the Company was obligated to make rental payments under operating lease agreements consisting primarily of ground leases related to 157 real estate investments, excluding those ground leases the Company has prepaid. As of December 31, 2023, the Company had 232 properties totaling 16.9 million square feet that were held under ground leases with a remaining weighted average term of 64.9 years, including renewal options. These ground leases typically have initial terms of 50 to 75 years with one or more renewal options extending the terms to 75 to 100 years, with expiration dates through 2119.

Purchase Options

The Company had approximately $111.1 million in real estate properties as of December 31, 2023 that were subject to exercisable purchase options. The Company has approximately $1.1 billion in real estate properties that are subject to purchase options that will become exercisable after 2023. Additional information about the amount and basis for determination of the purchase price is detailed in the table below (dollars in thousands):

1 Purchase option prices are based on fair market value components that are determined by an appraisal process, except for three properties totaling $45.3 million with stated prices or prices based on fixed capitalization rates.

2 These purchase options have been exercisable for an average of 13.9 years.

3 Includes two medical office buildings that are recorded in the line item Investment in financing receivable, net on the Company's Consolidated Balance Sheet.

Debt Management

The Company maintains a conservative and flexible capital structure that allows it to fund new investments and operate its existing portfolio. The Company has approximately$70.8 millionof mortgage notes payable, most of which were assumed when the Company acquired properties. The Company has approximately$24.1 million of mortgage notes payable that will mature in 2024. The Company will repay mortgages with cash on hand or borrowings under the Unsecured Credit Facility. See additional information in Liquidity and Capital Resources - Financing Activities.

Impact of Inflation

The Company is subject to the risk of inflation as most of its revenues are derived from long-term leases. Most of the Company's leases provide for fixed increases in base rents or increases based on the Consumer Price Index and require the tenant to pay all or some portion of increases in operating expenses. The Company believes that these provisions mitigate the impact of inflation. However, there can be no assurance that the Company's ability to increase rents or recover operating expenses will keep pace with inflation. The Company's leases have a weighted average lease term remaining of approximately 4.2 years. The Company has 94.9% of leases that provide for fixed base rent increases and 5.1% that provide for Consumer Price Index-based rent increases as of December 31, 2023.

New Accounting Pronouncements

See Note 1 to the Consolidated Financial Statements for information on new accounting standards including both standards that the Company adopted during the year and those that have not yet been adopted.
