EXPLANATORY NOTE
This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2026 of Kilroy Realty Corporation and Kilroy Realty, L.P. Unless stated otherwise or the context otherwise requires, references to “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” mean Kilroy Realty Corporation, a Maryland corporation, and its controlled and consolidated subsidiaries, and references to “Kilroy Realty, L.P.” or the “Operating Partnership” mean Kilroy Realty, L.P., a Delaware limited partnership, and its controlled and consolidated subsidiaries.
The Company is a real estate investment trust, or REIT, and the general partner of the Operating Partnership. As of March 31, 2026, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership and the remaining approximate 1.0% common limited partnership interest was owned by non-affiliated investors. As the sole general partner of the Operating Partnership, the Company exercises exclusive and complete discretion over the Operating Partnership’s day-to-day management and control.
We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how the Company and the Operating Partnership operate as an interrelated, consolidated company. The Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership owns substantially all of the assets of the Company either directly or through its subsidiaries, conducts the operations of the Company’s business, and is structured as a limited partnership with no publicly traded equity. Except for net proceeds from equity issuances by the Company, which the Company generally contributes to the Operating Partnership in exchange for units of partnership interest, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, the incurrence of indebtedness, or the issuance of units of partnership interest.
The presentation of noncontrolling interests, stockholders’ equity, and partners’ capital are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership. The differences between stockholders’ equity, partners’ capital, and noncontrolling interests result from the differences in the equity issued by the Company and the Operating Partnership.
We believe combining the quarterly reports on Form 10-Q of the Company and the Operating Partnership into this single report results in the following benefits:
Better reflects how management and the analyst community view the business as a single operating unit;
Enhances investors’ understanding of the Company and the Operating Partnership by enabling them to view the business as a whole and in the same manner as management;
Creates efficiencies for the Company and the Operating Partnership and result in savings in time, effort, and expense; and
Creates efficiencies for investors by reducing duplicative disclosure and providing a single document for their review.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1.    Organization, Ownership, and Basis of Presentation

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office, life science, and mixed-use property types in the United States. Our approach to modern business environments is designed to drive creativity and productivity for some of the world’s leading technology, media, life science, and professional services companies and we have been consistently recognized for our leadership in sustainability and building operations. We own, manage, develop, and acquire primarily premier office and life science properties in the San Francisco Bay Area, Los Angeles, Seattle, San Diego, and Austin, which are markets we believe have long-term strategic advantages and strong barriers to entry. The Company qualifies as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.”

We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the “Operating Partnership”) and conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context otherwise requires, the terms “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries, including the Operating Partnership, and the term “Operating Partnership” refers to Kilroy Realty, L.P. and its consolidated subsidiaries. The descriptions of our business, employees, and properties apply to both the Company and the Operating Partnership.

Our stabilized portfolio of operating properties was comprised of the following at March 31, 2026:
Number of
Buildings
Rentable
Square Feet
Number of
Tenants
Percentage 
Occupied (1)
Stabilized Office and Life Science Properties (2)

(2)Includes ancillary retail space.
Number of
Properties

Units
2026 Average Occupancy
Stabilized Residential Property
1608 95.0 %

Our stabilized portfolio includes all properties except properties under development and redevelopment or in the tenant improvement phase, undeveloped land, and real estate assets held for sale, if any. As of March 31, 2026, we classified two of our residential properties in Los Angeles, CA, as held for sale. See Note 2 “Dispositions and Real Estate Held for Sale” for additional information. Redevelopment properties are those for which we expect to spend significant costs to change their use, with the intention of improving economic return. Properties in the tenant improvement phase are ready for tenant modifications after reaching “cold shell condition,” which may require additional base building modifications. Projects in the tenant improvement phase are moved into our stabilized portfolio once the project reaches the earlier of 95% occupancy or one year from the date of the cessation of major base building construction activities. Capitalized development costs are transferred to relevant asset categories on the balance sheet as projects or phases of projects are placed in service.

Our stabilized portfolio also excludes our future development pipeline, which, as of March 31, 2026, was comprised of nine potential future development sites.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)



The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, and the following “Consolidated Property Partnerships”:

Consolidated Property PartnershipProperty Address
Ownership Interest (1) (2)
100 First Street Member, LLC (“100 First LLC”)
100 1st Street, San Francisco, CA 9410556%
303 Second Street Member, LLC (“303 Second LLC”)
303 2nd Street, San Francisco, CA 9410756%
Redwood City Partners, LLC (“Redwood LLC”)
900 Jefferson Avenue, Redwood City, CA 9406393%
900 Middlefield Road, Redwood City, CA 94063
1900 Broadway Partners, LLC (“1900 Broadway LLC”) (3)
1900 Broadway, Redwood City, CA 9406397%
________________________
(1)For 100 First Street LLC, 303 Second LLC, and Redwood LLC, reflects the Company’s ownership percentage at time of agreement. For Redwood LLC, actual percentage may vary depending on cash flows or promote structure. For 1900 Broadway LLC, reflects expected ownership percentage upon completion of construction.
(2)The remaining interests in all four property partnerships were owned by unrelated third parties.
(3)Represents a new consolidated subsidiary created on February 20, 2026. Refer to Note 7 “Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements” for additional information.

As of March 31, 2026, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership, and the remaining approximate 1.0% common limited partnership interest in the Operating Partnership was owned by non-affiliated investors. Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. Generally, the number of common units held by the Company is equivalent to the number of outstanding shares of the Company’s common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company’s common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership’s Seventh Amended and Restated Agreement of Limited Partnership, as amended (the “Partnership Agreement”).

With the exception of the Operating Partnership and our Consolidated Property Partnerships, all of our subsidiaries are wholly-owned. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, the Consolidated Property Partnerships, and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

The accompanying interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. The interim financial statements for the Company and the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2025.

During the three months ended March 31, 2026, the Company combined certain line items in the Consolidated Statements of Equity. The Company determined that separate disclosure for certain line items was not meaningful to the users of the financial statements. The settlement of restricted stock units for shares of common stock is now presented net of shares withheld and payments made to settle tax obligations. Historical presentation has been revised to conform with the current period presentation. These presentation changes did not affect the total equity balance, net income, or earnings per share in any of the periods reported.

Variable Interest Entities
The Operating Partnership is a variable interest entity (“VIE”) that is consolidated by the Company as the primary beneficiary, as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out or participating rights. At March 31, 2026, the consolidated financial statements of the Company included three VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC, and 1900 Broadway LLC. At December 31, 2025, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. The Company and the Operating Partnership were determined to be the primary beneficiaries of these VIEs at March 31, 2026 and December 31, 2025, since we had the ability to control the activities that most significantly

Revenues, income, and net assets generated by 100 First LLC, 303 Second LLC, and 1900 Broadway LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures, and required distributions.

We may be entitled to a temporary 0.01% reduction in the interest rate, provided we meet certain sustainability goals with respect to the ongoing reduction of greenhouse gas emissions.
(3)Our annual facility fee is paid on a quarterly basis and is calculated based on total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs in connection with the amendment and restatement of the unsecured revolving credit facility in 2024.

5.    Stockholders’ Equity of the Company

At-The-Market Stock Offering Program

Under our at-the-market (“ATM”) stock offering program (the “2024 ATM Program”), which commenced in March 2024, we may offer and sell shares of the Company’s common stock having an aggregate gross sales price of up to $500.0 million from time to time in “at-the-market” offerings. In connection with the 2024 ATM Program, the Company may also, at its discretion, enter into forward equity sale agreements. The use of forward equity sale agreements allows the Company to fix a share price on the sale of shares of our common stock at the time an agreement is executed but defer settling the forward equity sale agreements and receiving the proceeds from the sale of shares until a later date. The Company did not have any outstanding forward equity sale agreements to be settled at March 31, 2026. Since commencement of the 2024 ATM Program, we have not completed any sales of common stock.

Share Repurchase Program

Under our current share repurchase program, which commenced in February 2024 (the “Share Repurchase Program”), we are authorized to repurchase shares of the Company’s common stock having an aggregate gross purchase price of up to $500.0 million. Under the Share Repurchase Program, repurchases may be made from time to time using a variety of methods, which may include open market purchases and privately negotiated transactions. The specific timing, price, and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations. The Share Repurchase Program does not have a termination date and repurchases may be discontinued at any time. During the three months ended March 31, 2026, we repurchased 2,357,739 shares of common stock at a weighted average price of $30.80 per common share for an aggregate purchase price of $72.7 million. As of March 31, 2026, we are authorized to repurchase shares of the Company’s common stock having an aggregate gross purchase price of up to $427.3 million.

6.    Noncontrolling Interests on the Company’s Consolidated Financial Statements

Common Units of the Operating Partnership

The Company owned an approximate 99.0% and 99.1% common general partnership interest in the Operating Partnership as of March 31, 2026 and December 31, 2025, respectively. The remaining approximate 1.0% and 0.9% common limited partnership interest as of March 31, 2026 and December 31, 2025, respectively, was owned by non-affiliated investors in the form of noncontrolling common units. There were 1,133,562 common units outstanding held by these investors as of March 31, 2026 and December 31, 2025.

The noncontrolling common units may be redeemed by unitholders for cash. Except under certain circumstances, we, at our option, may satisfy the cash redemption obligation with shares of the Company’s common stock on a one-for-one basis. If satisfied in cash, the value for each noncontrolling common unit upon redemption is the amount equal to the average of the closing quoted price per share of the Company’s common stock, par value $0.01 per share, as reported on the NYSE for the ten trading days immediately preceding the applicable redemption date. The aggregate value upon redemption of the then-outstanding noncontrolling common units was $32.4 million and $43.2 million as of March 31, 2026 and December 31, 2025, respectively. This redemption value does not necessarily represent the amount that would be distributed with respect to each noncontrolling common unit in the event of our termination or liquidation. In the event of our termination or liquidation, it is generally expected that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution

7.    Noncontrolling Interests on the Operating Partnership’s Consolidated Financial Statements

Consolidated Property Partnerships

On February 20, 2026, the Company entered into an agreement with an unaffiliated third party and formed a new consolidated subsidiary. In connection with this formation, we acquired an approximately 1.1-acre land parcel for the future development project at 1900 Broadway in Redwood City, CA for $36.0 million, of which our joint venture partner contributed $9.0 million. We plan to develop an approximately 251,000-square-foot office project in Redwood City, California. At formation, the Company contributed $34.6 million in cash and has committed to contribute an additional $250.0 million to $270.0 million for an estimated ownership percentage of 97.4% upon completion. The related assets, liabilities, and noncontrolling interest recognized in connection with this transaction are included in the consolidated financial statements as of the date of formation. The noncontrolling equity interest was $9.0 million as of March 31, 2026.

During the three months ended March 31, 2026, the Board of Directors granted 6,448 RSUs to two newly elected Directors that are subject to time-based service vesting in two equal annual installments in February 2027 and February 2028. Each RSU granted is entitled to earn dividend equivalents in the form of RSUs that vest upon vesting of the underlying RSU award.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $5.8 million and $5.2 million for the three months ended March 31, 2026 and 2025, respectively. Of the total share-based compensation costs, $0.9 million and $1.2 million was capitalized as part of real estate assets for the three months ended March 31, 2026 and 2025, respectively.

15.    Segments

Operating segments are defined as components of an enterprise that engage in business activities from which they may earn revenues and incur expenses and about which discrete financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”). The CODM decides how resources are allocated and assesses performance on a recurring basis, at least quarterly. Our CODM is our Chief Executive Officer (“CEO”), who evaluates the operating performance and financial results of our consolidated portfolio based on Net (Loss) Income through monthly operations meetings.

We conduct our business on a consolidated basis in one operating segment and therefore have one reportable segment. Asset information by segment is not reported because the Company does not use this measure to assess performance.

Our reportable segment derives its revenues primarily from rental revenue and related property income through the leasing of commercial real estate space to tenants. We recognize revenue from base rent (fixed lease payments), additional rent (variable lease payments, which consist of amounts due from tenants for common area maintenance, real estate taxes, percentage rent, and other recoverable costs), parking, and other lease-related revenue.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion relates to our consolidated financial statements and should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. The results of operations discussion is combined for the Company and the Operating Partnership because there are no material differences in the results of operations between the two reporting entities.

Forward-Looking Statements

Statements contained in this “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” that are not historical facts may be forward-looking statements. Forward-looking statements include, among other things, statements or information concerning our plans, objectives, capital resources, portfolio performance, results of operations, projected future occupancy and rental rates, lease expirations, debt maturities, potential investments, strategies such as capital recycling, development and redevelopment activity, projected construction costs, projected construction commencement and completion dates, projected square footage of space that could be constructed on undeveloped land that we own, projected rentable square footage of or number of units in properties under construction or in the development pipeline, anticipated proceeds from capital recycling activity or other dispositions and anticipated dates of those activities or dispositions, projected increases in the value of properties, dispositions, future executive incentive compensation, pending, potential or proposed acquisitions, plans to grow our Net Operating Income and FFO, our ability to re-lease properties at or above current market rates, anticipated market conditions and demographics and other forward-looking financial data, as well as the discussion in “—Factors That May Influence Future Results of Operations,” “—Liquidity and Capital Resource of the Company,” and “—Liquidity and Capital Resources of the Operating Partnership.” Forward-looking statements can be identified by the use of words such as “believes,” “expects,” “projects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates”, or “anticipates” and the negative of these words and phrases and similar expressions that do not relate to historical matters. Forward-looking statements are based on our current expectations, beliefs, and assumptions, and are not guarantees of future performance. Forward-looking statements are inherently subject to uncertainties, risks, changes in circumstances, trends, and factors that are difficult to predict, many of which are outside of our control. Accordingly, actual performance, results, and events may vary materially from those indicated or implied in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future performance, results, or events. Numerous factors could cause actual future performance, results, and events to differ materially from those indicated in the forward-looking statements, including, among others: global market and general economic conditions, including actual and potential tariffs and periods of heightened inflation, and their effect on us and our tenants; adverse economic or real estate conditions generally, and specifically, in the states of California, Texas, and Washington; risks associated with our investment in real estate assets, which are illiquid, and with trends in the real estate industry; defaults on or non-renewal of leases by tenants; any significant downturn in tenants’ businesses, including bankruptcy, lack of liquidity or lack of funding, and the impact labor disruptions or strikes, such as episodic strikes in the media industry, may have on our tenants’ businesses; our ability to re-lease property at or above current market rates; reduced demand for office space, including as a result of remote working and flexible working arrangements that allow work from remote locations other than an employer’s office premises; costs to comply with government regulations, including environmental remediation; the availability of cash for distribution and debt service, and exposure to risk of default under debt obligations; increases in interest rates and our ability to manage interest rate exposure; changes in interest rates and the availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue development, redevelopment, and acquisition opportunities and refinance existing debt; a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices, or obtain or maintain debt financing, and which may result in write-offs or impairment charges; significant competition, which may decrease the occupancy and rental rates of properties; potential losses that may not be covered by insurance; the ability to successfully complete acquisitions and dispositions on announced terms; the ability to successfully operate acquired, developed, and redeveloped properties; the ability to successfully complete development and redevelopment projects on schedule and within budgeted amounts; delays or refusals in obtaining all necessary zoning, land use, and other required entitlements, governmental permits and authorizations for our development and redevelopment properties; increases in anticipated capital expenditures, tenant improvement, and/or leasing costs; defaults on leases for land on which some of our properties are located; adverse changes to, or enactment or implementations of, tax laws or other applicable laws, regulations, or legislation, as well as business and consumer reactions to such changes; risks associated with joint venture investments, including our lack of sole decision-making authority, our reliance on co-venturers’ financial condition and disputes between us and our co-venturers; environmental uncertainties and risks related to natural disasters; risks associated with climate change and our sustainability strategies, and our ability to achieve our sustainability goals; and our ability to maintain our status as a REIT. The factors included in this report are not exhaustive and additional factors could adversely affect our business and financial performance. For a discussion of additional factors that could materially adversely affect the

Company’s and the Operating Partnership’s business and financial performance, see the discussion below, as well as in “Part I, Item 1A. Risk Factors” and “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s and the Operating Partnership’s annual report on Form 10-K for the year ended December 31, 2025, and their respective other filings with the SEC. All forward-looking statements are based on currently available information and speak only as of the dates on which they are made. We assume no obligation to update any forward-looking statement that becomes untrue because of subsequent events, new information, or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws.

Overview and Background

We are a self-administered REIT active in premier office, life science, and mixed-use property types in the United States. We own, manage, develop, and acquire primarily premier office and life science properties in the San Francisco Bay Area, Los Angeles, Seattle, San Diego, and Austin, which are markets we believe have long-term strategic advantages and strong barriers to entry. We own our interests in all of our real estate assets and conduct substantially all of our operations through the Operating Partnership, of which we owned an approximate 99.0% and 99.1% common general partnership interest in as of March 31, 2026 and December 31, 2025, respectively. All of our properties and development and redevelopment projects are 100% owned, excluding four office properties and one future development project owned by the Consolidated Property Partnerships. As of March 31, 2026, all of our properties are held in fee except for the fourteen office buildings that are held subject to long-term ground leases.

Stabilized Portfolio Information

As of March 31, 2026, our stabilized portfolio was comprised of 123 office and life science properties encompassing an aggregate of approximately 17.1 million rentable square feet. This portfolio includes all properties except properties under development and redevelopment or in the tenant improvement phase, undeveloped land, and real estate assets held for sale, if any.

As of March 31, 2026, the following assets were excluded from our stabilized portfolio:

Factors That May Influence Future Results of Operations

Leasing

Leasing Activity and Changes in Rental Rates

The amount of rental income generated by our properties depends principally on our ability to maintain current occupancy rates and to lease currently available space, including space at newly developed or redeveloped properties and newly acquired properties. The amount of rental income we generate also depends on our ability to maintain or increase rental rates at our properties. Negative trends in one or more of these factors could adversely affect our rental income in future periods. The following tables set forth certain information regarding leasing activity during the three months ended March 31, 2026:

(2)Includes 100% of annualized base rent of the Consolidated Property Partnerships.
(3)Represents annualized monthly contractual base rents from existing tenants in occupancy, including the impact of straight-lined rent escalations and the amortization of free rent periods and excluding the impact of the following: amortization of deferred revenue related to tenant-funded tenant improvements, amortization of above / below-market rents, amortization for lease incentives due under existing leases, and expense reimbursement revenue. Amounts represent percentage of total portfolio annualized contractual base rental revenue.

Adjusting for leases that have been backfilled or released to a subtenant as of March 31, 2026 but not yet commenced, the remaining 2026, 2027, and 2028 expirations would be 727,003, 988,946, and 1,241,431 square feet, respectively.

Our rental rates and occupancy are impacted by general economic conditions, including the pace of regional economic growth and capital availability. Therefore, we cannot guarantee that leases will be renewed or that available space will be re-leased at rental rates equal to or above current rates.

Capital Recycling Program

Our capital recycling program plays a central role in reshaping our portfolio for long-term performance and cash flow durability. By disposing of select non-core or non-strategic assets, often in markets where growth prospects have moderated, as well as undeveloped land in our portfolio, we can redeploy capital into opportunities that can realize higher returns. Refer to “Liquidity and Capital Resources of the Operating Partnership” for further discussion of our capital recycling program.

Development and Redevelopment Programs

Stabilized Development Project

During the three months ended March 31, 2026, we completed and added the following development project to our stabilized portfolio:

Kilroy Oyster Point (Phase 2), South San Francisco, California. In June 2021, we commenced construction on Phase 2 of this 39-acre life science campus situated on the waterfront in South San Francisco and progressed the property to the tenant improvement phase during the first quarter of 2025. The second phase encompasses 871,738 square feet of office and life science space across three buildings with a total estimated investment of $1.2 billion. We added the property to the stabilized portfolio upon reaching one year since substantial completion. The project is 5% occupied and 44% leased.

Future Development Pipeline

(1)Project scope, including the estimated developable square feet or number of residential units, could change materially from estimates provided due to one or more of the following: significant changes in the economy, market conditions, tenant requirements and demands, construction costs, new supply, regulatory and entitlement processes, or project design.
(2)Represents costs incurred, including accrued liabilities in accordance with GAAP.
(3)Owned in a consolidated joint venture. Project is 58% pre-leased and is anticipated to commence construction in 2027, with delivery scheduled for 2030, at which time the Company’s ownership interest is expected to be 97%.
(4)Subject to signed purchase and sale agreements and non-refundable deposits as of the date of this filing. Both development sites are anticipated to close upon receipt of residential entitlements and permits, which is expected to occur beginning in phases in 2026.

Fluctuations in our development activities, including a slowdown in development activities, could cause fluctuations in the average development asset balances qualifying for interest and other carrying costs and internal cost capitalization under GAAP in future periods, resulting in higher interest and other expenses. The following table sets forth our capitalized interest and other capitalized costs for our development and redevelopment properties and capital improvement projects in the stabilized portfolio:

(2)Primarily represents compensation costs capitalized to construction and development and redevelopment projects.
(3)Represents incidental property operating and carry costs capitalized to development and redevelopment projects.

Inflation

The majority of the Company’s leases require tenants to reimburse the Company for the tenant’s proportionate share of, and/or increases in, real estate taxes and certain operating costs, which reduce the Company’s exposure to increases in operating costs resulting from inflation. The Company’s exposure to inflationary impacts is sensitive to fluctuations in the occupancy levels at its properties.

Results of Operations

Net Operating Income

Management internally evaluates the operating performance and financial results of our stabilized portfolio based on Net Operating Income. We define “Net Operating Income” as revenues less lease termination fees and consolidated operating expenses (property expenses, real estate taxes, and ground leases).

Net Operating Income is considered by management to be an important and appropriate supplemental performance measure to net income because we believe it helps both investors and management to understand the core operations of our properties. Net Operating Income is an unlevered operating performance metric of our properties and allows for a useful comparison of the operating performance of individual assets or groups of assets. Because the Company’s Net Operating Income metrics exclude lease termination fees, leasing costs, general and administrative expenses, interest expense, depreciation and amortization, other income and expenses, impairment of real estate assets, and gains and losses, they provide performance measures that, when compared year over year, reflect the consolidated revenues and expenses directly associated with owning and operating commercial real estate and the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing a perspective on operations not immediately apparent from net income. In addition, Net Operating Income is considered by many in the real estate industry to be a useful starting point for determining the value of a real estate asset or group of assets. Other real estate companies may use different methodologies for calculating Net Operating Income and, accordingly, our presentation of Net Operating Income may not be comparable to other real estate companies. Because of the exclusion of the items shown in the reconciliation below, Net Operating Income should only be used as a supplemental measure of our financial performance and not as an alternative to GAAP net income.

Management further evaluates Net Operating Income by evaluating the performance from the following property groups:

Same Property Portfolio – includes the consolidated results of all of the properties that were owned and included in our stabilized portfolio for two comparable reporting periods, i.e., owned and included in our stabilized portfolio as of January 1, 2025 and still owned and included in the stabilized portfolio as of March 31, 2026, including our residential property in San Diego, California;

Re/Development Properties – includes the results generated by certain of our in-process development and redevelopment projects, expenses for certain of our future development projects, and the results generated by the two stabilized redevelopment properties that were added to the stabilized portfolio in the third quarter of 2025 and the one property added to the stabilized portfolio in the first quarter of 2026;

Acquisition Properties – includes the results, from the date of acquisition through the periods presented, of the following:
One property acquired in the third quarter of 2025; and
One property, comprised of four buildings, acquired in the fourth quarter of 2025; and

Disposition and Held for Sale Properties – includes the results of the following:
One property disposed of in the second quarter of 2025;
One property, comprised of four buildings, disposed of in the third quarter of 2025;
One property disposed of in the fourth quarter of 2025;
Two properties, comprised of four buildings, disposed of in the first quarter of 2026; and
Two residential properties, totaling 393 residential units, classified as held for sale as of March 31, 2026.

Net Operating Income decreased $1.8 million, or 1.0%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily resulting from:

A decrease of $10.4 million, attributable to the Disposition and Held for Sale Properties; and

A decrease of $2.7 million, attributable to the Re/Development Properties, primarily due to one development property added to the stabilized portfolio in the first quarter of 2026, which resulted in the cessation of cost capitalization.

Partially offset by:

An increase of $6.0 million, attributable to the Acquisition Properties; and

An increase of $5.3 million, or 3.2%, attributable to the Same Property Portfolio, which was driven by the following activity:

An increase in total operating revenues of $4.6 million, or 1.9%, primarily due to a(n):

$3.1 million increase in straight-line rent, primarily due to a $6.0 million increase from newly commenced leases with rent abatements, partially offset by aging leases where cash rent now exceeds GAAP rent on a straight-line basis;

$1.9 million increase in revenue associated with tenant creditworthiness considerations that resulted in higher non-recurring charges in 2025;

$0.8 million increase in revenues from recoverable operating expenses;

$0.7 million increase in transient parking income and residential income; and

$0.3 million increase in settlement and restoration fee income.

Partially offset by:

$2.1 million decrease in net base rent, primarily due to the above-mentioned $6.0 million increase in abated rent, mainly in the San Francisco Bay Area and Seattle regions, partially offset by a $3.6 million increase from higher rates and a $0.3 million increase due to increased occupancy; and

$0.1 million decrease in amortization of deferred income and tenant funded improvements, mainly resulting from tenant move outs.

A decrease in property and related expenses of $0.7 million, or 0.9%, primarily due to a(n):

32


$1.0 million decrease in real estate taxes, primarily due to a net increase in refunds of $1.4 million received in 2026, partially offset by a $0.4 million increase resulting from higher assessed property values.

Partially offset by:

$0.3 million increase in property expenses and ground rent expense.

Lease Termination Fees

Lease termination fees decreased $0.1 million, or 21.3%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to a lease termination fee recognized for one tenant in 2025 in the Seattle region.

General and Administrative Expenses

General and administrative expenses increased $3.8 million, or 22.5%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to an increase in compensation expense of $2.7 million resulting from increased headcount and a reduction in the amount of labor capitalized to development and redevelopment properties and capital improvement projects.

Depreciation and Amortization

Depreciation and amortization increased $7.2 million, or 8.3%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to the following:

An increase of $7.5 million attributable to a full quarter of expense related to the Acquisition Properties;

An increase of $4.6 million attributable to the Re/Development Properties, primarily due to the one property added to the stabilized portfolio in the first quarter of 2026; and

An increase of $1.2 million attributable to the Same Property Portfolio, primarily due to revenue recognition commencing for one tenant in the Seattle region in the third quarter of 2025.

Partially offset by:

A decrease of $6.1 million attributable to the Disposition and Held for Sale Properties.

Interest Income

Interest income decreased $0.2 million, or 15.9%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to lower average interest rates on our interest-bearing accounts.

Interest Expense

The following table sets forth our gross interest expense and capitalized interest:

Gross interest expense, before the effect of capitalized interest, increased $0.8 million, or 1.6%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to an increase in the weighted average interest rate for the three months ended March 31, 2026.
33



Capitalized interest decreased $6.6 million, or 31.9%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to the stabilization of the one development property added to the stabilized portfolio during the three months ended March 31, 2026, at which point we stopped capitalizing interest. Capitalized interest will vary based on the current status of active development or redevelopment projects and our future development pipeline. For additional information about the potential impact of inflation on our interest expense and construction costs, and the impact on our business, financial condition, results of operations, cash flows, liquidity, and ability to satisfy our debt service obligations, refer to “Part I, Item IA. Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2025.

Liquidity and Capital Resources of the Company

In this “Liquidity and Capital Resources of the Company” section, the term the “Company” refers only to Kilroy Realty Corporation on an unconsolidated basis and excludes the Operating Partnership and all other subsidiaries. As the sole general partner with control of the Operating Partnership, the Company consolidates the Operating Partnership for financial reporting purposes, and the Company does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities and the revenues and expenses of the Company and the Operating Partnership are substantially the same on their respective financial statements. The section entitled “Liquidity and Capital Resources of the Operating Partnership” should be read in conjunction with this section to understand the liquidity and capital resources of the Company on a consolidated basis and how the Company is operated as a whole.

Our liquidity, access to capital, and ability to execute our business strategy are subject to a variety of risks and uncertainties. Our ability to obtain financing, raise capital through dispositions or joint ventures, recycle capital through tax‑deferred transaction structures, fund development activity, or pursue acquisition opportunities will depend on a number of factors, many of which are outside of our control. These factors include conditions in the public and private capital markets, interest rate and inflation trends, the availability and cost of debt and equity financing, the demand for our properties, the timing and pricing of potential dispositions, the performance of our development projects, and broader macroeconomic and geopolitical conditions.

Distributions from the Operating Partnership are the Company’s primary source of capital. The Company believes the Operating Partnership’s sources of working capital, specifically its cash flows from operations, borrowings available under its unsecured revolving credit facility, and funds from its capital recycling program, including strategic ventures, are adequate for it to make its distribution payments to the Company to make dividend payments to its common stockholders for the next twelve months. The unavailability of capital could adversely affect the Operating Partnership’s ability to make distributions to the Company, which would in turn adversely affect the Company’s ability to pay cash dividends to its stockholders.

The Company is a well-known seasoned issuer and the Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company and the Operating Partnership of certain securities in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing, and capital needs. When the Company receives proceeds from the sales of its securities, it generally contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership.

Liquidity Highlights

As of March 31, 2026, we had approximately $192.9 million in cash and cash equivalents and $1.1 billion available under our unsecured revolving credit facility. We believe that our available liquidity makes us well positioned to navigate any additional future uncertainties.

Distribution Requirements

The Company is required to distribute 90% of its taxable income (subject to certain adjustments and excluding net capital gains) on an annual basis to maintain qualification as a REIT for federal income tax purposes. As a result of these distribution requirements, the Operating Partnership cannot rely on retained earnings to fund its on-going operations to the same extent as other companies whose parent companies are not REITs. In addition, the Company may be required to use borrowings under the Operating Partnership’s revolving credit facility, if necessary, to meet REIT distribution requirements and maintain its REIT status. The Company may also need to raise capital to fund the Operating Partnership’s working capital needs, as well as potential developments of new or existing properties or acquisitions.

The Company intends to continue to make, but has not committed to making, regular quarterly cash distributions to common stockholders. All such distributions are at the discretion of the Board of Directors. The Company considers market factors and its performance in addition to REIT requirements in determining its distribution levels. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which is consistent with the Company’s intention to maintain its qualification as a REIT. Such investments may include, for example, obligations of the Government National Mortgage Association, other governmental agency securities, certificates of deposit, and interest-bearing bank deposits.
35



On February 24, 2026, the Board of Directors declared a regular quarterly cash dividend of $0.54 per share of common stock. The regular quarterly cash dividend was payable to stockholders of record on March 31, 2026 and a corresponding cash distribution of $0.54 per Operating Partnership unit was payable to holders of the Operating Partnership’s common limited partnership interests of record on March 31, 2026, including those owned by the Company. The total cash quarterly dividends and distributions paid on April 8, 2026 were $63.4 million.

The covenants contained within certain of our unsecured debt obligations generally prohibit the Company from making distribution payments during an event of default except to the extent that such payments result in distributions sufficient to (i) maintain our qualification as a REIT for federal and state income tax purposes, and (ii) avoid the payment of federal or state income or excise tax.

Capitalization

As of March 31, 2026, our total debt as a percentage of total market capitalization was 58.3%, as shown in the following table:

Liquidity and Capital Resources of the Operating Partnership

In this “Liquidity and Capital Resources of the Operating Partnership” section, the terms “we,” “our,” and “us” refer to the Operating Partnership or the Operating Partnership and the Company together, as the context requires.

General

Our primary liquidity sources and uses are as follows:

Liquidity Sources

Net cash flows from operations;
Proceeds from our capital recycling program, including the disposition of assets and the formation of strategic ventures;
Proceeds from additional secured or unsecured debt financings;
Borrowings under the Operating Partnership’s unsecured revolving credit facility; and
Proceeds from equity or preferred equity securities.

Liquidity Uses

Debt service and principal payments, including debt maturities, debt repurchases, and redemptions;
Capital expenditures, tenant improvements, and leasing costs;
Development and redevelopment costs;
Operating property or undeveloped land acquisitions;
Distributions to common security holders; and
Repurchases and redemptions of outstanding common stock of the Company.

General Strategy

Our general strategy is to maintain a conservative balance sheet with a strong credit profile and to maintain a capital structure that allows for financial flexibility and diversification of capital resources. We manage our capital structure to reflect a long-term investment approach and utilize multiple sources of capital to meet our long-term capital requirements. We believe that our current projected liquidity requirements for the next twelve-month period, as set forth above under the caption “—Liquidity Uses,” will be satisfied using a combination of the liquidity sources listed above, although there can be no assurance in this regard. We believe our disciplined capital structure and staggered debt maturities provide us with financial flexibility and enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we are well-positioned to refinance or repay maturing debt and to pursue our strategy of seeking attractive acquisition opportunities, which we may finance, as necessary, with future public and private issuances of debt and equity securities, although there can be no assurance in this regard.

We may be entitled to a temporary 0.01% reduction in the interest rate, provided we meet certain sustainability goals with respect to the ongoing reduction of greenhouse gas emissions.
(3)Our annual facility fee is paid on a quarterly basis and is calculated based on total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs in connection with the amendment and restatement of the unsecured revolving credit facility in 2024.

(4)The maturity date may be extended by a 12-month period, at the Operating Partnership’s election.

Capital Recycling Program

As discussed in the section “Factors That May Influence Future Results of Operations - Capital Recycling Program,” we continuously evaluate opportunities for the potential disposition of non-core properties and undeveloped land in our portfolio, or the formation of strategic ventures, with the intent of using the proceeds generated to acquire new operating and development properties, finance development and redevelopment expenditures, repay long-term debt, and for other general corporate purposes.

In connection with our capital recycling strategy, during the three months ended March 31, 2026, we completed the sale of two operating properties to unaffiliated third parties for gross proceeds totaling approximately $145.5 million. As of March 31, 2026, we had two residential properties, comprised of 393 residential units, classified as held for sale, with a gross sales price of $202.0 million. The sale of these properties closed in April 2026. The timing of any potential future disposition or strategic venture transactions will depend on market conditions and other factors, including, but not limited to, our capital needs, the
38


availability of financing for potential buyers (which has been and may continue to be constrained due to current economic and market conditions), and our ability to absorb or defer some or all of the taxable gains on the sales.

Shelf Registration Statement

The Company and the Operating Partnership have an effective shelf registration statement that provides for the public offering and sale from time to time by the Company and the Operating Partnership of certain securities in unlimited amounts. The Company evaluates the capital markets on an ongoing basis for opportunities to raise capital, and, as circumstances warrant, the Company and the Operating Partnership may issue securities in one or more offerings at any time and from time to time on an opportunistic basis, depending upon, among other things, market conditions, available pricing, and capital needs. When the Company receives proceeds from the sales of its preferred or common stock, it generally contributes the net proceeds from those sales to the Operating Partnership in exchange for corresponding preferred or common partnership units of the Operating Partnership. The Operating Partnership may use these proceeds and proceeds from the sale of its debt securities to repay debt, including borrowings under its unsecured revolving credit facility and unsecured term loan facility, to develop new or redevelop existing properties, to make acquisitions of properties or portfolios of properties, or for general corporate purposes.

At-The-Market Stock Offering Program

Under the 2024 ATM Program, which commenced in March 2024, we may offer and sell shares of the Company’s common stock having an aggregate gross sales price of up to $500.0 million from time to time in “at-the-market” offerings. In connection with the 2024 ATM Program, the Company may also, at its discretion, enter into forward equity sale agreements. The use of forward equity sale agreements allows the Company to fix a share price on the sale of shares of our common stock at the time an agreement is executed but defer settling the forward equity sale agreements and receiving the proceeds from the sale of shares until a later date. The Company did not have any outstanding forward equity sale agreements to be settled at March 31, 2026. Since commencement of the 2024 ATM Program, we have not completed any sales of common stock.

Liquidity Uses

Contractual Obligations

Refer to our 2025 Annual Report on Form 10-K for a discussion of our contractual obligations. There have been no material changes outside of the ordinary course of business to these contractual obligations during the three months ended March 31, 2026, with the exception of the additional development commitments for 1900 Broadway. As of March 31, 2026, we have committed to contribute $225.0 million to $245.0 million toward this project through 2030, of which, $20.0 million to $30.0 million is expected to be spent in 2026.

Other Liquidity Uses

Potential Future Leasing Costs and Capital Improvements

The amounts we incur for tenant improvements and leasing costs depend on leasing activity in each period. Tenant improvements and leasing costs generally fluctuate in any given period depending on factors such as the type and condition of the property, the term of the lease, the type of the lease, the involvement of external leasing agents, and overall market conditions, including the level of inflation. Capital expenditures may fluctuate in any given period subject to the nature, extent, and timing of improvements required to maintain our properties and may be impacted by inflationary pressures on the cost of construction materials.

Development

We believe we may spend between $100.0 million to $150.0 million on development projects throughout the remainder of 2026. The ultimate timing of these expenditures may fluctuate given construction progress and leasing status of the projects, or as a result of events outside our control, such as delays or increased costs as a result of heightened inflation and market conditions. We expect that any material additional development activities will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, or strategic venture opportunities. We cannot provide assurance that development projects will be completed on the terms, for the amounts, or on the timelines currently contemplated, or at all.

Potential Future Acquisitions

As discussed in the section Factors That May Influence Future Results of Operations - Capital Recycling Program,” we continue to evaluate strategic opportunities and remain a disciplined buyer of core, value-add, and strategic operating properties and land, dependent on market conditions and business cycles, among other factors. We focus on growth opportunities primarily in markets populated by knowledge and creative-based tenants in a variety of industries, including technology, media, healthcare, life sciences, and professional services. We expect that any material acquisitions will be funded with borrowings under the unsecured revolving credit facility, the public or private issuance of debt or equity securities, the disposition of assets under our capital recycling program, the formation of strategic ventures, or through the assumption of existing debt, although there can be no assurance in this regard.

Share Repurchase Program

Under our current share repurchase program, which commenced in February 2024 (the “Share Repurchase Program”), we are authorized to repurchase shares of the Company’s common stock having an aggregate gross purchase price of up to $500.0 million. Under the Share Repurchase Program, repurchases may be made from time to time using a variety of methods, which may include open market purchases and privately negotiated transactions. The specific timing, price, and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations. The Share Repurchase Program does not have a termination date and repurchases may be discontinued at any time. During the three months ended March 31, 2026, we repurchased 2,357,739 shares of common stock at a weighted average price of $30.80 per common share for an aggregate purchase price of $72.7 million. As of March 31, 2026, we are authorized to repurchase shares of the Company’s common stock having an aggregate gross purchase price of up to $427.3 million.

Factors That May Influence Future Sources of Capital and Liquidity of the Company and the Operating Partnership

We continue to evaluate sources of financing for our business activities, including borrowings under the unsecured revolving credit facility, the unsecured term loan facility, issuance of public and private equity securities, unsecured debt and fixed-rate secured mortgage financing, proceeds from the disposition of selective assets through our capital recycling program, and the formation of strategic ventures. However, our ability to obtain new financing or refinance existing borrowings on favorable terms could be impacted by various factors, including the state of the macroeconomy, the state of the credit and equity markets, significant tenant defaults, a decline in the demand for commercial real estate properties, a decrease in market rental rates or market values of real estate assets in our submarkets, the amount of our future borrowings and uncertainty related to interest rates, inflation rates, geopolitical events, and other factors (refer to “Part I, Item IA. Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2025 for additional information). These events could result in the following:

A decrease in our cash flows from operations, which could create further dependence on the unsecured revolving credit facility;

An increase in the proportion of variable-rate debt, which could increase our sensitivity to interest rate fluctuations in the future; and

A decrease in the value of our properties, which could have an adverse effect on the Operating Partnership’s ability to incur additional debt, refinance existing debt at competitive rates, or comply with its existing debt obligations.

In addition to the factors noted above, the Operating Partnership’s credit ratings are subject to ongoing evaluation by credit rating agencies and may be changed or withdrawn by a rating agency in the future if, in its judgment, circumstances warrant.

Financial Covenants and Restrictions

The unsecured revolving credit facility, unsecured term loan facility, unsecured senior notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. The Operating Partnership was in compliance with all of its financial covenants as of March 31, 2026. Our current expectation is that the Operating Partnership will continue to meet the requirements of its financial covenants in both the short and long term. However, in the event of an economic slowdown or continued volatility in the credit markets, there is no certainty that the Operating Partnership will be able to continue to satisfy all the covenant requirements.

Consolidated Historical Cash Flows Summary

The following summary discussion of our consolidated historical cash flows is based on the consolidated statements of cash flows in Item 1. “Financial Statements” and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below. Changes in our cash flows include changes in cash and cash equivalents. Our historical cash flow activity is as follows:
 Three Months Ended March 31,
 20262025Dollar

Net increase (decrease) in cash and cash equivalents
$13,588 $(18,979)$32,567 (171.6)%

Operating Activities

Our cash flows from operating activities depends on numerous factors including the occupancy level of our portfolio, the rental rates achieved on our leases, the collectability of rent and recoveries from our tenants, the level of operating expenses, the impact of property acquisitions, completed development and redevelopment projects and related financing activities, and other general and administrative costs. See additional information under the caption “—Results of Operations.” Our net cash provided by operating activities increased by $13.8 million, or 10.1%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to the timing of outflows related to annual insurance premium payments, as well as an increase in accrued property taxes payable during the three months ended March 31, 2026.

Investing Activities

Our cash flows from investing activities are generally used to fund development and operating property acquisitions, expenditures for development and redevelopment projects, recurring and nonrecurring capital expenditures for our operating properties, and include net proceeds received from dispositions of real estate assets. We had net cash provided by investing activities of $15.0 million for the three months ended March 31, 2026 as compared to net cash used in investing activities of $76.7 million for the three months ended March 31, 2025, primarily due to the net proceeds received from the dispositions of our two operating properties during the three months ended March 31, 2026, partially offset by a $34.6 million payment in connection with a newly formed consolidated subsidiary, which includes the acquisition of a 1.1‑acre land parcel for a future development project. We did not dispose of any operating properties during the three months ended March 31, 2025.

Financing Activities

Our cash flows from financing activities are principally impacted by our capital raising activities, net of dividends and distributions paid to common stockholders and common unitholders. Our net cash used in financing activities increased by $72.9 million, or 92.0%, for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025, primarily due to the common stock repurchases made during the three months ended March 31, 2026 under our current Share Repurchase Program.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the reporting periods. We base our estimates on historical experience, current market conditions, and various other assumptions that are believed to be reasonable under the circumstances. Actual results could materially differ from these estimates.

In our Annual Report on Form 10-K for the year ended December 31, 2025, we identified certain critical accounting policies that affect certain of our more significant estimates and assumptions used in preparing our consolidated financial statements. We have not made any material changes to our critical accounting policies and estimates during the period covered by this report.

Non-GAAP Supplemental Financial Measure: Funds From Operations (“FFO”)

We calculate FFO available to common stockholders and common unitholders in accordance with the 2018 Restated White Paper on FFO approved by the Board of Governors of Nareit. The White Paper defines FFO as net income or loss (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. The reconciling items include amounts to adjust earnings from consolidated partially-owned entities and equity in earnings of unconsolidated affiliates to FFO. Our calculation of FFO includes the amortization of deferred revenue related to tenant-funded tenant improvements and excludes the depreciation of the related tenant improvement assets. We also add back net income attributable to noncontrolling common units of the Operating Partnership because we report FFO attributable to common stockholders and common unitholders.

We believe that FFO is a useful supplemental measure of our operating performance. The exclusion from FFO of gains and losses from the sale of operating real estate assets allows investors and analysts to readily identify the operating results of the assets that form the core of our activity and assists in comparing those operating results between periods. Also, because FFO is generally recognized as the industry standard for reporting the operations of REITs, it facilitates comparisons of operating performance to other REITs. However, other REITs may use different methodologies to calculate FFO, and accordingly, our FFO may not be comparable to all other REITs.

Implicit in historical cost accounting for real estate assets in accordance with GAAP is the assumption that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, many industry investors and analysts have considered presentations of operating results for real estate companies using historical cost accounting alone to be insufficient. Because FFO excludes depreciation and amortization of real estate assets, we believe that FFO along with the required GAAP presentations provides a more complete measurement of our performance relative to our competitors and a more appropriate basis on which to make decisions involving operating, financing, and investing activities than the required GAAP presentations alone would provide.

FFO should not be viewed as an alternative measure of our operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, which are significant economic costs and could materially impact our results from operations.
