EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2023 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 June 30, 2023, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.0% common limited partnership interests are owned by non-affiliated investors and certain directors and officers of the Company. 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 and can cause it to enter into certain major transactions, including acquisitions, dispositions, and refinancings and cause changes in its line of business, capital structure and distribution policies.

There are a few differences between the Company and the Operating Partnership that are reflected in the disclosures in this Form 10-Q. 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 is a REIT, the only material asset of which is the partnership interests it holds in the Operating Partnership. As a result, the Company generally 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 Company itself is not directly obligated under any indebtedness, but generally guarantees all of the 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, by the Operating Partnership’s incurrence of indebtedness or through the issuance of units of partnership interest.

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 common limited partnership interests in the Operating Partnership are accounted for as partners’ capital in the Operating Partnership’s financial statements and, to the extent not held by the Company, as noncontrolling interests in the Company’s financial statements. The differences between stockholders’ equity, partners’ capital and noncontrolling interest 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:

•Combined reports better reflect how management and the analyst community view the business as a single operating unit;

•Combined reports enhance 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;

•Combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and

•Combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

•consolidated financial statements;

•the following notes to the consolidated financial statements:

◦Note 9, Net Income Available to Common Stockholders Per Share of the Company;

◦Note 10, Net Income Available to Common Unitholders Per Unit of the Operating Partnership;

◦Note 11, Supplemental Cash Flow Information of the Company; and

◦Note 12, Supplemental Cash Flow Information of the Operating Partnership;

i

•“Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

◦—Liquidity and Capital Resources of the Company;” and

◦—Liquidity and Capital Resources of the Operating Partnership.”

This report also includes separate sections under “Part I – Financial Information, Item 4. Controls and Procedures” and separate Exhibit 31 and Exhibit 32 certifications for the Company and the Operating Partnership to establish that the Chief Executive Officer and the Chief Financial Officer of each entity have made the requisite certifications and that the Company and Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 18 U.S.C. §1350.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

1.    Organization, Ownership and Basis of Presentation

Organization and Ownership

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office, life science and mixed-use submarkets in the United States. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in Greater Los Angeles, San Diego County, the San Francisco Bay Area, Greater Seattle and Austin, Texas, which we believe have strategic advantages and strong barriers to entry. Class A real estate encompasses attractive and efficient buildings of high quality that are attractive to tenants, are well-designed and constructed with above-average material, workmanship and finishes and are well-maintained and managed. We qualify 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”). We generally conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context indicates otherwise, the terms “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries 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 properties at June 30, 2023:

	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage  Occupied (1)		Percentage Leased
Stabilized Office Properties (2)	119	16,214,594	401	86.6	%	88.6	%

________________________

(1)Represents economic occupancy.

(2)Includes stabilized life science and retail space.

	Number of Projects	Number of Units	2023 Average Occupancy
Stabilized Residential Properties	3	1,001	93.0	%

Our stabilized portfolio includes all of our properties with the exception of development properties currently committed for construction, under construction, or in the tenant improvement phase, redevelopment properties under construction, undeveloped land and real estate assets held for sale. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define properties in the tenant improvement phase as office and life science properties that we are developing or redeveloping where the project has reached cold shell condition and is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to 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. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets at the historical cost of the property as the projects or phases of projects are placed in service.

As of June 30, 2023, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	2	805,000
In-process development projects - under construction	1	875,000
In-process redevelopment projects - under construction	2	100,000

________________________

(1)Estimated rentable square feet upon completion.

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

We did not have any properties held for sale at June 30, 2023. Our stabilized portfolio also excludes our future development pipeline, which as of June 30, 2023 was comprised of eight future development sites, representing approximately 64 gross acres of undeveloped land.

As of June 30, 2023, all of our properties, development projects and redevelopment projects were owned and all of our business was conducted in the state of California with the exception of ten stabilized office properties and one future development project located in the state of Washington, and one development project in the tenant improvement phase and one future development project in Austin, Texas. All of our properties, development projects and redevelopment projects are 100% owned, excluding four office properties owned by three consolidated property partnerships. Two of the three consolidated property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”), each owned one office property in San Francisco, California through subsidiary REITs. As of June 30, 2023, the Company owned a 56% common equity interest in both 100 First LLC and 303 Second LLC. The third consolidated property partnership, Redwood City Partners, LLC (“Redwood LLC”) owned two office properties in Redwood City, California. As of June 30, 2023, the Company owned an approximate 93% common equity interest in Redwood LLC. The remaining interests in all three property partnerships were owned by unrelated third parties.

Ownership and Basis of Presentation

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

As of June 30, 2023, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.0% common limited partnership interest in the Operating Partnership as of June 30, 2023 was owned by non-affiliated investors and certain of our executive officers and directors. 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 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, 2023. 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, 2022.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

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 June 30, 2023, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At June 30, 2023, the Company and the Operating Partnership were determined to be the primary beneficiaries of these two VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of June 30, 2023, the two VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $423.0 million (of which $354.7 million related to real estate held for investment), approximately $25.9 million and approximately $175.4 million, respectively. Revenues, income and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions.

At December 31, 2022, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At December 31, 2022, the Company and the Operating Partnership were determined to be the primary beneficiaries of these two VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. At December 31, 2022, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by approximately $438.7 million (of which $362.7 million related to real estate held for investment), approximately $31.5 million and approximately $179.4 million, respectively.

2.    Prepaid Expenses and Other Assets, Net

Prepaid expenses and other assets, net consisted of the following at June 30, 2023 and December 31, 2022:

3.    Secured and Unsecured Debt of the Operating Partnership

The Company generally guarantees all of the Operating Partnership’s unsecured debt obligations including the unsecured revolving credit facility, the unsecured term loan facility and all of the unsecured senior notes.

Unsecured Revolving Credit Facility and Term Loan Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of June 30, 2023 and December 31, 2022:

Maturity date (4)	July 31, 2025

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

________________________

(1)Total borrowing capacity is reduced by the amount of our outstanding letters of credit which total approximately $5.2 million as of the date of this report. We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $500.0 million under an accordion feature under the terms of the unsecured revolving credit facility.

(2)Our unsecured revolving credit facility interest rate was calculated using a contractual rate of Secured Overnight Financing Rate (“SOFR”) plus a SOFR adjustment of 0.10% (“Adjusted SOFR”) and a margin of 0.900% based on our credit rating as of June 30, 2023 and December 31, 2022. 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 facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $4.3 million and $5.3 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the maturity date of our unsecured revolving credit facility.

(4)The maturity date may be extended by two six-month periods, at the Company’s option.

The Company intends to borrow under the unsecured revolving credit facility from time to time for general corporate purposes, to finance development and redevelopment expenditures, to fund potential acquisitions and to potentially repay long-term debt and to supplement cash balances given uncertainties and volatility in market conditions.

In January 2023, the Operating Partnership entered into the first amendment to its existing unsecured term loan facility agreement to (i) exercise the accordion feature under the term loan agreement to provide for $100.0 million of additional term loan commitments and (ii) increase the borrowing capacity under the accordion feature to provide additional term loan commitments or add one or more tranches of term loans up to an aggregate amount of $650.0 million. In March 2023, the Operating Partnership further amended the unsecured term loan facility agreement to exercise the accordion feature to provide for $20.0 million of additional term loan commitments, bringing the total borrowing capacity of the unsecured term loan facility to $520.0 million.

The following table summarizes the balance and terms of our unsecured term loan facility as of June 30, 2023 and December 31, 2022:

	June 30, 2023			December 31, 2022
	(in thousands)
Outstanding borrowings	$	350,000		$	200,000
Remaining borrowing capacity	170,000			200,000
Total borrowing capacity (1)	$	520,000		$	400,000
Interest rate (2)	6.17		%	5.23		%
Undrawn facility fee-annual rate (3)	0.200%
Maturity date (4)	October 3, 2024

____________________

(1)We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $130.0 million and $100.0 million as of June 30, 2023 and December 31, 2022, respectively, under an accordion feature under the terms of the unsecured term loan facility.

(2)Our unsecured term loan facility interest rate was calculated using a contractual rate of Adjusted SOFR plus a margin of 0.950% based on our credit rating as of June 30, 2023 and December 31, 2022.

(3)Our undrawn facility fee is paid on a quarterly basis and is calculated based on the remaining borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $3.8 million and $4.5 million, respectively, of unamortized deferred financing costs remained to be amortized through the maturity date of our unsecured term loan facility.

(4)The maturity date may be extended by two twelve-month periods, at the Company’s option.

Debt Covenants and Restrictions

The unsecured revolving credit facility, unsecured term loan facility, the unsecured senior notes, including the private placement notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a maximum ratio of secured debt to total asset value, a minimum unsecured debt ratio and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full principal balance of the associated debt becoming immediately due and payable. We were in compliance with all of our debt covenants as of June 30, 2023.

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

Common Units of the Operating Partnership

The Company owned an approximate 99.0% common general partnership interest in the Operating Partnership as of June 30, 2023, December 31, 2022 and June 30, 2022. The remaining approximate 1.0% common limited partnership interest as of June 30, 2023, December 31, 2022 and June 30, 2022 was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 1,150,574 common units outstanding held by these investors, executive officers and directors as of June 30, 2023, December 31, 2022 and June 30, 2022.

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 $34.4 million and $44.7 million as of June 30, 2023 and December 31, 2022, 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 expected in most cases that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution payable in respect of each share of the Company’s common stock.

5.    Share-Based Compensation

Stockholder Approved Share-Based Incentive Compensation Plan

As of June 30, 2023, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). The Company has a currently effective registration statement registering 12.6 million shares of our common stock for possible issuance under our 2006 Plan. As of June 30, 2023, approximately 2.9 million shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) for which the performance period has been completed and (ii) at maximum levels for the other performance and market conditions (as defined below) for awards still in a performance period.

Executive Transitions

On March 30, 2023, our Chief Executive Officer (“CEO”) announced his retirement effective December 31, 2023. Additionally, as previously disclosed, the Company and our former President entered into a separation agreement in 2022 under which he continued to serve as an officer of the Company until the scheduled expiration date of his employment agreement on March 1, 2023.

For our CEO, the vesting of all unvested share-based compensation awards is being accelerated through December 31, 2023 and the final number of any restricted stock units (“RSUs”) subject to market and/or performance-based vesting requirements that vest will be based upon a shortened performance period ending on December 31, 2023. Share-based compensation expense for these awards will be recognized based on our current assumption of the achievement of market and/or performance-based vesting requirements for the shortened performance periods. For our former President, the vesting of all unvested share-based compensation awards was accelerated through March 1, 2023 and the final number of RSUs earned that were subject to market and/or performance-based vesting requirements was based upon the actual achievement of the market and/or performance conditions for a shortened performance period ending on March 1, 2023. For the three and six months ended June 30, 2023, we recognized $5.4 million and $13.2 million, respectively, of stock compensation expense related to the accelerated vesting of awards for our CEO and former President.

2023 Share-Based Compensation Grants

In February 2023, the Executive Compensation Committee of the Company’s Board of Directors awarded 517,066 restricted stock units to certain officers of the Company under the 2006 Plan, which included 300,007 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2023 Performance-Based RSUs”) and 217,059 RSUs that are subject to time-based vesting requirements (the “2023 Time-Based RSUs”).

2023 Performance-Based RSU Grant

The 2023 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2023-2025), except for our CEO, whose RSUs are scheduled to vest on his announced retirement date of December, 31, 2023. A target number of 2023 Performance-Based RSUs were awarded, and the final number of 2023 Performance-Based RSUs that vest (which may be more or less than the target number) will be based upon (1) during the first calendar year of the three year performance measurement period, the achievement of pre-set FFO per share goals that applies to 100% of the Performance-Based RSUs awarded (the “FFO Performance Condition”) and (2) a performance measure that applies to 50% of the award based upon a measure of the Company’s average debt to EBITDA ratio for the three year performance period (the “Debt to EBITDA Ratio Performance Condition”) and a market measure that applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three year performance period compared to the total stockholder returns of an established comparison group of companies over the same period (the “Market Condition”). The 2023 Performance-Based RSUs are also subject to a three year service vesting provision (the “service vesting condition”) and are scheduled to cliff vest on the date the final vesting percentage is determined following the end of the three year performance period under the awards. The number of 2023 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2023 Performance-Based RSUs granted based upon the levels of achievement for the FFO Performance Condition, the Debt to EBITDA Ratio Performance Condition, the Market Condition, and the extent to which the service vesting condition

15

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

is satisfied. The estimate of the number of 2023 Performance-Based RSUs earned is evaluated quarterly during the performance period based on our estimate for each of the performance conditions measured against the applicable goals.

Compensation expense for the 2023 Performance-Based RSU grant is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three year service period, except for our CEO, whose compensation expense is recognized on an accelerated basis through his announced retirement date of December 31, 2023. During the six months ended June 30, 2023, we recognized $4.2 million of compensation expense for the 2023 Performance-Based RSU grant assuming the 2023 FFO Performance Condition is met at 111% of the target level of achievement (116.5% for our CEO) and the 2023 Debt to EBITDA Ratio Performance Condition is met at 100% of the target level of achievement (175.0% for our CEO). In the event we achieve a lower level of performance or fail to meet the FFO performance condition, we would reverse a portion or all of the $4.2 million of compensation expense.

Each 2023 Performance-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by the Company’s level of achievement of the applicable performance and market conditions. The fair value of the portion of the award subject to the Debt to EBITDA Ratio Performance Condition was calculated using the closing price of the Company’s common stock on the valuation date noted below. The fair value of the portion of the award subject to the Market Condition was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below, which resulted in the following grant date fair value per share.

	Fair Value Assumptions
Valuation date	February 6, 2023
Fair value per share on valuation date (1)	$40.10
Expected share price volatility	35.0%
Risk-free interest rate	4.12%

________________________ 

(1)For one participant, the fair value per share on the valuation date for their 2023 Performance-Based RSUs is $40.43.

The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the remaining performance period as of the grant date and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at February 6, 2023.

The fair value of the 2023 Performance-Based RSU grant as of the valuation date noted above, based on a target level of achievement, was $12.0 million. For the three and six months ended June 30, 2023, we recorded compensation expense based upon the grant date fair value per share for each component multiplied by the estimated number of RSUs to be earned.

2023 Time-Based RSU Grant

The 2023 Time-Based RSUs are scheduled to vest in three equal annual installments beginning on January 5, 2024 through January 5, 2026. Compensation expense for the 2023 Time-Based RSUs is recognized on a straight-line basis over the requisite service period, which is generally the explicit service period except for our CEO, whose compensation expense is recognized on an accelerated basis through his announced retirement date of December 31, 2023. Each 2023 Time-Based RSU represents the right to receive one share of our common stock in the future, subject to continued employment through the applicable vesting date, unless accelerated upon separation of employment, provided certain conditions are met. The total grant date fair value of the 2023 Time-Based RSU awards was $8.6 million, which was based on the $39.65 closing share price of the Company’s common stock on the NYSE on the February 6, 2023 grant date.

2022 and 2021 Performance-Based RSUs

Compensation cost for the 2022 performance-based RSUs for the three and six months ended June 30, 2023 assumes the 2022 Debt to EBITDA Ratio Performance Condition is met at 150% of the target level of achievement (175.0% for our CEO). Compensation cost for the 2021 performance-based RSUs for the three and six months ended June 30, 2023 assumes the 2021 Debt to EBITDA Ratio Performance Condition is met at 150% of the target level of achievement (175.0% for our CEO).

KILROY REALTY CORPORATION AND KILROY REALTY, L.P.

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $9.5 million and $9.7 million for the three months ended June 30, 2023 and 2022, respectively, and $21.0 million and $16.3 million for the six months ended June 30, 2023 and 2022, respectively. Share-based compensation costs for the three and six months ended June 30, 2023 include $5.4 million and $13.2 million, respectively, of accelerated share-based compensation costs for our CEO and former President as discussed above. Of the total share-based compensation costs, $1.8 million and $3.3 million was capitalized as part of the real estate assets for the three and six months ended June 30, 2023, respectively, and $1.7 million and $3.0 million was capitalized as part of the real estate assets for the three and six months ended June 30, 2022, respectively. As of June 30, 2023, there was approximately $34.1 million of total unrecognized compensation cost related to nonvested RSUs granted under share-based compensation arrangements. Such amount is based in part upon the estimated future outcome of the performance metrics as of June 30, 2023, and the actual compensation cost ultimately recognized could increase or decrease from this estimate based upon actual performance results. These costs are expected to be recognized over a weighted-average period of 1.3 years, which includes the shortened vesting period for our CEO due to his announced retirement on December 31, 2023. The remaining compensation cost related to these nonvested RSU awards had been recognized in periods prior to June 30, 2023.

6.    Rental Income and Future Minimum Rent

Our rental income is primarily comprised of payments defined under leases and are subject to scheduled fixed increases. Additionally, rental income includes variable payments for tenant reimbursements of property-related expenses and payments based on a percentage of tenant’s sales.

The table below sets forth the allocation of rental income between fixed and variable payments and net collectability reversals or recoveries for the three and six months ended June 30, 2023 and 2022:

We have operating leases with tenants that expire at various dates through 2048 and are subject to scheduled fixed increases. Generally, the leases grant tenants renewal options. Leases also provide for additional rents based on certain operating expenses. Future contractual minimum rent under operating leases, which includes amounts contractually due from leases that are on a cash basis of reporting due to creditworthiness considerations, as of June 30, 2023 for future periods is summarized as follows:

On July 12, 2023, aggregate dividends, distributions and dividend equivalents of $64.4 million were paid to common stockholders, common unitholders and RSU holders of record on June 30, 2023.

On July 20, 2023, certain of our and the Operating Partnership’s subsidiaries entered into a $375.0 million mortgage loan transaction (the “Loan”) secured by, among other things, a deed of trust, assignment of leases and rents, security agreement and fixture filing encumbering two office buildings, 608 apartment units and over 95,000 square feet of retail at the Company’s One Paseo mixed-use campus in Del Mar, California. The Loan matures on August 10, 2034, bears interest at an annual rate of 5.90% and requires monthly interest payments only. In addition, the Operating Partnership has entered into a guaranty in favor of the lender in connection with the Loan. The Loan is generally non-recourse to the Operating Partnership, but the lender has recourse to the Operating Partnership for certain recourse exceptions.

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.

Overview and Background

We are a self-administered REIT active in premier office, life science and mixed-use submarkets in the United States. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in Greater Los Angeles, San Diego County, the San Francisco Bay Area, Greater Seattle and Austin, Texas, which we believe have strategic advantages and strong barriers to entry. We own our interests in all of our real properties through the Operating Partnership and generally conduct substantially all of our operations through the Operating Partnership. We owned an approximate 99.0% general partnership interest in the Operating Partnership as of June 30, 2023, December 31, 2022 and June 30, 2022. As of June 30, 2023, all of our properties are held in fee except for the fourteen office buildings that are held subject to long-term ground leases for the land.

Factors That May Influence Future Results of Operations

Development and Redevelopment Programs

We believe that a portion of our long-term future growth will continue to come from the completion of our in-process development and redevelopment projects and, subject to market conditions, executing on our future development pipeline, including expanding entitlements. Over the past several years, we increased our focus on development and redevelopment opportunities and expanded our future development pipeline through targeted acquisitions of development opportunities on the West Coast and in Austin, Texas.

We have a proactive planning process by which we continually evaluate the size, timing, costs and scope of our development and redevelopment programs and, as necessary, scale activity to reflect the economic conditions and the real estate fundamentals that exist in our submarkets. We expect to execute on our development and redevelopment programs with prudence and will be pursuing opportunities with attractive economic returns in strategic locations with proximity to public transportation or transportation access and retail amenities and in markets with strong fundamentals and visible demand. We plan to develop in phases, as appropriate, and we generally favor starting projects with pre-leasing activity.

In-Process Development Projects - Tenant Improvement

As of June 30, 2023, the following projects were in the tenant improvement phase:

•Indeed Tower, Austin CBD, Austin, Texas. We acquired this project upon core/shell completion in June 2021. This project encompasses approximately 734,000 square feet of office space at a total estimated investment of $690.0 million and is 74% leased to 14 tenants with 42% of the space leased to Indeed, Inc. through 2034. We currently expect this project to reach stabilization in the fourth quarter of 2023 upon one year passing since substantial completion.

•9514 Towne Centre Drive, University Towne Center, San Diego, California. We commenced construction on this project in September 2021 and completed base building components and moved the project into the tenant improvement phase in April 2023. This project is comprised of approximately 71,000 square feet of office space at a total estimated investment of $60.0 million. We completed construction and added the building to our stabilized portfolio in July. The building is 100% leased to a global technology company.

In-Process Development Projects - Under Construction

As of June 30, 2023, we had one project in our in-process development pipeline that was under construction:

•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. The second phase encompasses

24

approximately 875,000 square feet of office space across three buildings at a total estimated investment of $940.0 million.

In-Process Redevelopment - Under Construction

As of June 30, 2023, we had two redevelopment projects under construction:

•4690 Executive Drive, University Towne Center, San Diego, California. In March 2022, we began the phased redevelopment of this property, comprised of approximately 52,000 square feet for life science use with total estimated redevelopment costs of $25.0 million, inclusive of the depreciated basis of the building. The building was previously 100% leased to Sorrento Therapeutics, which declared Chapter 11 bankruptcy in February 2023 and rejected the lease on May 2, 2023. We are actively continuing the base building build-out in order to re-lease the building to another life science tenant.

•4400 Bohannon Drive, Menlo Park, California. In December 2022, we began the redevelopment of this property, comprised of approximately 48,000 square feet, for life science use with total estimated redevelopment costs of $55.0 million, inclusive of the depreciated basis of the building.

Future Development Pipeline

As of June 30, 2023, our future development pipeline included eight future projects located in Greater Los Angeles, San Diego County, the San Francisco Bay Area, Greater Seattle and Austin with an aggregate cost basis of approximately $1.3 billion at which we believe we could develop more than 7.0 million rentable square feet for a total estimated investment of approximately $8.0 billion to $9.0 billion, depending on successfully obtaining entitlements and market conditions.

The following table sets forth information about our future development pipeline.

Future Development Pipeline	Location	Approx. Developable Square Feet (1)	Total Costs as of 6/30/2023 ($ in millions) (2)

(1)Represents developable office/life science square feet. The developable square feet and scope of projects could change materially from estimated data provided due to one or more of the following: any significant changes in the economy, market conditions, our markets, tenant requirements and demands, construction costs, new supply, regulatory and entitlement processes or project design.

(2)Represents cash paid and costs incurred, including accrued liabilities in accordance with GAAP, as of June 30, 2023.

Fluctuations in our development activities could cause fluctuations in the average development asset balances qualifying for interest and other carrying cost and internal cost capitalization in future periods. During the three and six months ended June 30, 2023, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $1.9 billion and $1.8 billion, respectively, as it was determined these projects qualified for interest and other carrying cost capitalization under GAAP. In the event of an extended cessation of development activities, such projects may potentially no longer qualify for capitalization of interest or other carrying costs. For the three and six months ended June 30, 2023, we capitalized $19.5 million and $37.2 million, respectively, of interest to our qualifying

25

development and redevelopment projects. For the three and six months ended June 30, 2023, we capitalized $3.9 million and $8.5 million, respectively, of internal costs to our qualifying development and redevelopment projects.

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 recycling the proceeds generated into capital used to fund new operating and development acquisitions, to finance development and redevelopment expenditures, to repay long-term debt and for other general corporate purposes. As part of this strategy, we attempt to enter into transactions intended to qualify as like-kind exchanges pursuant to Section 1031 of the Code (“Section 1031 Exchanges”) and other tax deferred transaction structures, when possible, to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further discussion of our capital recycling activities.

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 availability of financing for potential buyers (which has been and may continue to be constrained for some potential buyers due to the current economic and market conditions), and our ability to defer some or all of the taxable gains on the sales. We cannot assure that we will dispose of any additional properties, enter into any additional strategic ventures, or that we will be able to identify and complete the acquisition of a suitable replacement property to effect a Section 1031 Exchange or be able to use other tax deferred structures in connection with our strategy. See the “Liquidity and Capital Resources of the Operating Partnership – Liquidity Sources” section for further information.

Acquisitions. As part of our growth strategy, which is highly dependent on market conditions and business cycles, among other factors, we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add and strategic operating properties and land. 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, entertainment and professional services.  Against the backdrop of market volatility, we expect to manage a strong balance sheet and selectively evaluate opportunities that we believe have the potential to either add immediate Net Operating Income to our portfolio or play a strategic role in our future growth.

In connection with our growth strategy, we often have one or more potential acquisitions of properties and/or undeveloped land under consideration that are in varying stages of negotiation and due diligence review, or under contract, at any point in time. However, we cannot provide assurance that we will enter into any agreements to acquire properties or undeveloped land, or that the potential acquisitions contemplated by any agreements we may enter into in the future will be completed. In addition, acquisitions are subject to various risks and uncertainties and we may be unable to complete an acquisition after making a nonrefundable deposit or incurring acquisition-related costs.

Incentive Compensation. Our Executive Compensation Committee determines compensation, including cash bonuses and equity incentives, for our executive officers, as defined in Rule 16 under the Exchange Act. For 2023, the annual cash bonus program was structured to allow the Executive Compensation Committee to evaluate a variety of key quantitative and qualitative metrics at the end of the year and make a determination based on the Company’s and management’s overall performance. Our Executive Compensation Committee also grants equity incentive awards from time to time that include performance-based and/or market-measure based vesting requirements and time-based vesting requirements. As a result, accrued incentive compensation and compensation expense for future awards may be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions, liquidity measures and other factors. Consequently, we cannot predict the amounts that will be recorded in future periods related to such incentive compensation.

As of June 30, 2023, there was approximately $34.1 million of total unrecognized compensation cost related to outstanding nonvested RSUs granted under share-based compensation arrangements. Such amount is based in part upon the estimated future outcome of the performance metrics as of June 30, 2023, and the actual compensation cost ultimately recognized could increase or decrease from this estimate based upon actual performance results. The costs are expected to be recognized over a weighted-average period of 1.3 years, which includes the shortened vesting period for our Chief Executive Officer due to his announced retirement on December 31, 2023. The $34.1 million of unrecognized compensation cost does not reflect the future compensation cost for any potential share-based awards that may be issued subsequent to June 30, 2023. Share-based compensation expense for potential future awards could be affected by our operating and development performance, financial results, stock price, performance against applicable performance-based vesting goals, market conditions and other factors. For additional information regarding our equity incentive awards, see Note 5 “Share-Based Compensation” to our consolidated financial statements included in this report.

Information on Leases Commenced and Executed

Leasing Activity and Changes in Rental Rates. The amount of net rental income generated by our properties depends principally on our ability to maintain the occupancy rates of currently leased space and to lease currently available space, newly developed or redeveloped properties, newly acquired properties with vacant space, and space available from unscheduled lease terminations. The amount of rental income we generate also depends on our ability to maintain or increase rental rates in our submarkets. 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 and six months ended June 30, 2023.

(1)Includes 100% of consolidated property partnerships.

(2)Represents leasing activity for leases that commenced or were signed during the period in the stabilized and development and redevelopment portfolios, net of month-to-month leases.

(3)Tenant improvements and leasing commissions per square foot exclude tenant-funded tenant improvements.

(4)Calculated as the change between GAAP rents for new/renewed leases and the expiring GAAP rents for the same space. Space that was vacant when the property was acquired is excluded from our change in rents calculations to provide a more meaningful market comparison.

(5)Calculated as the change between stated rents for new/renewed leases and the expiring stated rents for the same space. Space that was vacant when the property was acquired is excluded from our change in rents calculations to provide a more meaningful market comparison.

(6)Second generation leasing includes space where we have made capital expenditures to maintain the current market revenue stream.

(7)Represents leases commenced or executed on new construction added to the stabilized portfolio, as well as in our development and redevelopment portfolios where we have made capital expenditures that resulted in additional revenue generated when the space was re-leased.

(8)During the three months ended June 30, 2023, 15 new leases totaling 142,313 rentable square feet were signed but not commenced. During the six months ended June 30, 2023, 20 new leases totaling 280,100 rentable square feet were signed but not commenced.

(9)Calculated as the percentage of space either renewed or expanded into by existing tenants or subtenants at lease expiration.

27

As of June 30, 2023, we believe that the weighted average cash rental rates for our total stabilized portfolio are approximately 5-10% below the current average market rental rates. Individual properties within any particular submarket presently may be leased either above, below, or at the current market rates within that submarket, and the average rental rates for individual submarkets may be above, below, or at the average cash rental rate or our portfolio.

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

During the six months ended June 30, 2023, we saw an increase in physical occupancy at our properties and commitments by large corporations to in-office work by mandating a minimum number of days employees must work in the office. However, we believe that economic uncertainty and hybrid/remote working arrangements have impacted the timing and volume of leasing and will likely continue to do so in the future. Additionally, decreased demand (including as a result of remote work), increased competition (including sublease space available from our tenants) and other negative trends or unforeseeable events that impair our ability to timely renew or re-lease space could have negative effects on our future financial condition, results of operations, and cash flows.

Scheduled Lease Expirations. The following tables set forth certain information regarding our lease expirations for our stabilized portfolio for the remainder of 2023 and the next five years and by region for the remainder of 2023 and in 2024.

(1)For leases that have been renewed early with existing tenants, the expiration date and annualized base rent information presented takes into consideration the renewed lease terms. Excludes leases not commenced as of June 30, 2023, space leased under month-to-month leases, storage leases, vacant space and future lease renewal options not executed as of June 30, 2023.

(2)Annualized base rent includes the impact of straight-lining rent escalations and the amortization of free rent periods and excludes the impact of the following: amortization of deferred revenue related tenant-funded tenant improvements, amortization of above/below market rents, amortization for lease incentives due under existing leases and expense reimbursement revenue. Additionally, the underlying leases contain various expense structures, including full service gross, modified gross and triple net. Percentages represent percentage of total portfolio annualized contractual base rental revenue. For additional information on tenant improvement and leasing commission costs incurred by the Company for the current reporting period, please see further discussion under the caption “Information on Leases Commenced and Executed.”

(3)Includes 100% of annualized base rent of consolidated property partnerships.

(4)Adjusting for leases executed as of June 30, 2023 but not yet commenced, the 2023 and 2024 expirations would be reduced by 71,920 and 18,791 square feet, respectively.

28

In addition to the 2.2 million rentable square feet, or 13.4%, of currently available space in our stabilized portfolio, leases representing approximately 4.2% and 7.8% of the occupied square footage of our stabilized portfolio are scheduled to expire during the remainder of 2023 and in 2024, respectively. The leases scheduled to expire during the remainder of 2023 and in 2024 represent approximately 1.7 million rentable square feet or 10.3% of our total annualized base rental revenue. Adjusting for leases executed as of June 30, 2023 but not yet commenced, the remaining 2023 and 2024 expirations would be 504,754 and 1,061,141 square feet, respectively.

Sublease Space. Of our leased space as of June 30, 2023, approximately 1.5 million rentable square feet, or 9.4% of the square footage in our stabilized portfolio, was available for sublease, primarily in the San Francisco Bay Area region. Of the 9.4% of available sublease space in our stabilized portfolio as of June 30, 2023, approximately 7.4% was vacant space, and the remaining 2.0% was occupied. Of the approximately 1.5 million rentable square feet available for sublease as of June 30, 2023, no leases are scheduled to expire in 2023 and approximately 238,822 rentable square feet representing seven leases are scheduled to expire in 2024.

Stabilized Portfolio Information

As of June 30, 2023, our stabilized portfolio was comprised of 119 office and life science properties encompassing an aggregate of approximately 16.2 million rentable square feet and 1,001 residential units. Our stabilized portfolio includes all of our properties with the exception of development properties currently committed for construction, under construction or in the tenant improvement phase, redevelopment projects under construction, undeveloped land and real estate assets held for sale. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define properties in the tenant improvement phase as office and life science properties that we are developing or redeveloping where the project has reached cold shell condition and is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to 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. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets at the historical cost of the property as the projects or phases of projects are placed in service.

We did not have any properties held for sale at June 30, 2023. Our stabilized portfolio also excludes our future development pipeline, which as of June 30, 2023 was comprised of eight potential development sites, representing approximately 64 gross acres of undeveloped land on which we believe we have the potential to develop more than 7.0 million rentable square feet, depending upon economic conditions.

As of June 30, 2023, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	2	805,000
In-process development projects - under construction	1	875,000
In-process redevelopment projects - under construction	2	100,000

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 consolidated operating revenues (rental income and other property income) less 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 excluding corporate and financing-related costs and non-cash depreciation and amortization. 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. This measure thereby provides an operating perspective not immediately apparent from GAAP income from operations or 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 income from operations or net income.

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

•Same Store Properties – includes the consolidated results of all of the office 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, 2022 and still owned and included in the stabilized portfolio as of June 30, 2023, including our three residential properties in Hollywood and Del Mar, California;

•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 following stabilized development properties:

◦One office building that was added to the stabilized portfolio in the second quarter of 2022; and

◦Three office buildings that were added to the stabilized portfolio in the third quarter of 2022; and

•Disposition Properties – includes the results of one property disposed of in the third quarter of 2022.

The following table sets forth certain information regarding the property groups within our stabilized office portfolio as of June 30, 2023:

Group	# of Buildings	Rentable Square Feet
Same Store Properties	115	15,063,476
Stabilized Development Properties (1)	4	1,151,118
Total Stabilized Portfolio	119	16,214,594

Net Operating Income increased $4.6 million, or 2.4%, for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022 resulting from:

•A decrease in Net Operating Income of $4.3 million attributable to the Same Store Properties, which was driven by the following activity:

•An increase in total operating revenues of $0.2 million primarily due to:

•$4.1 million increase in the tenant reimbursement component of rental income primarily due to higher reimbursable operating expenses; and

•$2.1 million net increase in non-recurring revenue related to tenant restoration fees and revenue adjustments for tenant creditworthiness considerations; partially offset by

•$6.0 million net decrease comprised of $8.4 million decrease from lease expirations net of $2.4 million increase from new leases and renewals at higher rates;

•An increase in property and related expenses of $4.5 million primarily due to the following:

•$3.5 million increase in property expenses including utilities, insurance, security, janitorial, contract services, parking and various other recurring expenses predominately related to our tenants’ continued return to the office and cost increases; and

•$0.9 million increase in annual property taxes; and

•A decrease in Net Operating Income of $0.6 million attributable to the Disposition Properties; offset by

•An increase in Net Operating Income of $9.5 million attributable to the Development Properties, of which $5.6 million was contributed by Indeed Tower primarily due to a full quarter of revenue recognition on the leased space to Indeed, Inc.

Other Expenses and Income

General and Administrative Expenses

General and administrative expenses increased $0.5 million, or 2.4%, for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022 due to costs associated with succession planning for our CEO’s previously announced retirement.

34

Depreciation and Amortization

Depreciation and amortization decreased $6.1 million, or 6.3%, for the three months ended June 30, 2023 compared to the three months ended June 30, 2022, primarily due to the following:

•A decrease of $3.9 million attributable to the Same Store Properties;

•A decrease of $1.9 million attributable to the Development Properties; and

•A decrease of $0.3 million attributable to the Disposition Properties.

Interest Expense

The following table sets forth our gross interest expense, including debt discounts and deferred financing cost amortization, and capitalized interest, including capitalized debt discounts and deferred financing cost amortization, for the three months ended June 30, 2023 and 2022:

	Three Months Ended June 30,
	2023		2022		Dollar Change		Percentage Change
	(in thousands)
Gross interest expense	$	45,853	$	39,612	$	6,241	15.8	%
Capitalized interest and deferred financing costs	(19,470)		(19,491)		21		(0.1)	%
Interest expense	$	26,383	$	20,121	$	6,262	31.1	%

Gross interest expense, before the effect of capitalized interest and deferred financing costs, increased $6.2 million, or 15.8%, for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022, primarily due to an increase in the average outstanding debt balance for the three months ended June 30, 2023.

Capitalized interest and deferred financing costs remained generally consistent for the three months ended June 30, 2023 as compared to the three months ended June 30, 2022. During the three months ended June 30, 2023 and 2022, we capitalized interest on in-process development and redevelopment projects and future development pipeline projects with an average aggregate cost basis of approximately $1.9 billion and $2.1 billion, respectively. In the event of an extended cessation of development or redevelopment activities to get any of these projects ready for its intended use, such projects could potentially no longer qualify for capitalization of interest or other carrying costs.

Net Income Attributable to Noncontrolling Interests in Consolidated Property Partnerships

Net income attributable to noncontrolling interests in consolidated property partnerships decreased $1.2 million or 18.9% for the three months ended June 30, 2023 compared to the three months ended June 30, 2022 primarily due to a lease termination during the first quarter of 2023 at one property held in a consolidated property partnership. The amounts reported for the three months ended June 30, 2023 and 2022 are comprised of the noncontrolling interest’s share of net income for 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”) and the noncontrolling interest’s share of net income for Redwood City Partners, LLC (“Redwood LLC”).

During the six months ended June 30, 2023 and 2022, we capitalized interest on in-process development projects and future development pipeline projects with an average aggregate cost basis of approximately $1.8 billion and $2.0 billion, respectively. In the event of an extended cessation of development or redevelopment activities to get any of these projects ready for its intended use, such projects could potentially no longer qualify for capitalization of interest or other carrying costs. Refer to “Part I, Item IA. Risk Factors” in our annual report on Form 10-K for the year ended December 31, 2022 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.

Net Income Attributable to Noncontrolling Interests in Consolidated Property Partnerships

Net income attributable to noncontrolling interests in consolidated property partnerships increased $1.1 million or 9.3% for the six months ended June 30, 2023 compared to the six months ended June 30, 2022 primarily due to a non-recurring restoration fee, partially offset by lower rental income due to a lease termination during the first quarter of 2023 at one property held in a consolidated property partnership. The amounts reported for the six months ended June 30, 2023 and 2022 are comprised of the noncontrolling interest’s share of net income for 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”) and the noncontrolling interest’s share of net income for Redwood City Partners, LLC (“Redwood LLC”).

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.

The Company’s business is operated primarily through the Operating Partnership. 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 flow from operations and borrowings available under its unsecured revolving credit facility and unsecured term loan facility and funds from its capital recycling program, including strategic ventures, are adequate for it to make its distribution payments to the Company and, in turn, for the Company to make its dividend payments to its common stockholders for the next twelve months. Cash flows from operating activities generated by the Operating Partnership for the six months ended June 30, 2023 were sufficient to cover the Company’s payment of cash dividends to its stockholders. However, there can be no assurance that the Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including its ability to make distributions to the Company. 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 of its preferred stock, common stock, depositary shares, warrants and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case 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 of all of these types 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.

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.

Liquidity Highlights

As of June 30, 2023, we had approximately $361.9 million in cash and cash equivalents. During March 2023, we increased the total borrowing capacity of the unsecured term loan facility to $520.0 million and borrowed an additional $150.0 million. As of the date of this report, we had approximately $1.1 billion available under our unsecured revolving credit facility and $170.0 million available under our unsecured term loan facility. Excluding our unsecured term loan facility, for which we have two twelve-month extension options, our next debt maturity occurs in December 2024. We believe that our available liquidity demonstrates a strong balance sheet and makes us well positioned to navigate any additional future uncertainties. In addition, the Company is a well-known seasoned issuer and has historically been able to raise capital on a timely basis in the public markets, as well as the private markets. Any future financings, however, will depend on market conditions for both capital raises and the investment of such proceeds, and there can be no assurances that we will successfully obtain such financings.

39

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 and is required to pay income tax at regular corporate rates to the extent it distributes less than 100% of its taxable income (including capital gains). 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 continue to raise capital in the equity markets 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 make, regular quarterly cash distributions to common stockholders, and through the Operating Partnership, to common unitholders from the Operating Partnership’s cash flow from operating activities. All such distributions are at the discretion of the Board of Directors. As the Company intends to maintain distributions at a level sufficient to meet the REIT distribution requirements and minimize its obligation to pay income and excise taxes, it will continue to evaluate whether the current levels of distribution are appropriate to do so throughout 2023. In addition, in the event the Company is unable to successfully complete Section 1031 Exchanges to defer some or all of the taxable gains related to property dispositions (or in the event additional legislation is enacted that further modifies or repeals laws with respect to Section 1031 Exchanges), the Company may be required to distribute a special dividend to its common stockholders and common unitholders in order to minimize or eliminate income taxes on such gains. 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.

On May 24, 2023, the Board of Directors declared a regular quarterly cash dividend of $0.54 per share. The regular quarterly cash dividend is payable to stockholders of record on June 30, 2023 and a corresponding cash distribution of $0.54 per Operating Partnership unit is payable to holders of the Operating Partnership’s common limited partnership interests of record on June 30, 2023, including those owned by the Company. The total cash quarterly dividends and distributions paid on July 12, 2023 were $63.9 million.

Debt Covenants

The covenants contained within certain of our unsecured debt obligations generally prohibit the Company from paying dividends during an event of default in excess of an amount which results in distributions to us in an amount sufficient to permit us to pay dividends to our stockholders that we reasonably believe are necessary to (a) maintain our qualification as a REIT for federal and state income tax purposes and (b) avoid the payment of federal or state income or excise tax.

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 flow from operations;

•Borrowings under the Operating Partnership’s unsecured revolving credit facility and unsecured term loan facility;

•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; and

•Proceeds from public or private issuance of debt, equity or preferred equity securities.

Liquidity Uses

•Property operating and corporate expenses;

•Capital expenditures, tenant improvement and leasing costs;

•Development and redevelopment costs;

•Operating property or undeveloped land acquisitions;

•Debt service and principal payments, including debt maturities;

•Distributions to common security holders;

•Repurchases and redemptions of outstanding common stock of the Company; and

•Outstanding debt repurchases, redemptions and repayments.

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 conservative leverage 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.

Liquidity Sources

Unsecured Revolving Credit Facility and Term Loan Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of June 30, 2023 and December 31, 2022:

	June 30, 2023			December 31, 2022
	(in thousands)
Outstanding borrowings	$	—		$	—
Remaining borrowing capacity	1,100,000			1,100,000
Total borrowing capacity (1)	$	1,100,000		$	1,100,000
Interest rate (2)	6.09		%	5.20		%
Facility fee-annual rate (3)	0.200%
Maturity date (4)	July 31, 2025

________________________

(1)Total borrowing capacity is reduced by the amount of our outstanding letters of credit which total $5.2 million as of the date of this report. We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $500.0 million under an accordion feature under the terms of the unsecured revolving credit facility.

(2)Our unsecured revolving credit facility interest rate was calculated using a contractual rate of Secured Overnight Financing Rate (“SOFR”) plus a SOFR adjustment of 0.10% (“Adjusted SOFR”) and a margin of 0.900% based on our credit rating as of June 30, 2023 and December 31, 2022. 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 facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $4.3 million and $5.3 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the respective maturity dates presented of our unsecured revolving credit facility.

(4)The maturity date may be extended by two six-month periods, at the Company’s option.

We intend to borrow under the unsecured revolving credit facility as necessary for general corporate purposes, to finance development and redevelopment expenditures, to fund potential acquisitions and to potentially repay long-term debt to supplement cash balances given uncertainties and volatility in market conditions.

In January 2023, the Operating Partnership entered into the first amendment to its existing unsecured term loan facility agreement to (i) exercise the accordion feature under the term loan agreement to provide for $100.0 million of additional term loan commitments and (ii) increase the borrowing capacity under the accordion feature to provide additional term loan commitments or add one or more tranches of term loans up to an aggregate amount of $650.0 million. In March 2023, the Operating Partnership further amended the unsecured term loan facility agreement to exercise the accordion feature to provide for $20.0 million of additional term loan commitments, bringing the total borrowing capacity of the unsecured term loan facility to $520.0 million.

The following table summarizes the balance and terms of our unsecured term loan facility as of June 30, 2023 and December 31, 2022:

	June 30, 2023			December 31, 2022
	(in thousands)
Outstanding borrowings	$	350,000		$	200,000
Remaining borrowing capacity	170,000			200,000
Total borrowing capacity (1)	$	520,000		$	400,000
Interest rate (2)	6.17		%	5.23		%
Undrawn facility fee-annual rate (3)	0.200%
Maturity date (4)	October 3, 2024

____________________

(1)We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $130.0 million and $100.0 million as of June 30, 2023 and December 31, 2022, respectively, under an accordion feature under the terms of the unsecured term loan facility.

(2)Our unsecured term loan facility interest rate was calculated using a contractual rate of Adjusted SOFR plus a margin of 0.950% based on our credit rating as of June 30, 2023 and December 31, 2022.

(3)Our undrawn facility fee is paid on a quarterly basis and is calculated based on the remaining borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $3.8 million and $4.5 million, respectively, of unamortized deferred financing costs remained to be amortized through the maturity date of our unsecured term loan facility.

(4)The maturity date may be extended by two twelve-month periods, at the Company’s option.

43

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 properties and undeveloped land in our portfolio or the formation of strategic ventures with the intent of recycling the proceeds generated from the disposition of less strategic or core assets into capital used to finance development and redevelopment expenditures, to fund new acquisitions, to repay long-term debt and for other general corporate purposes. As part of this strategy, we attempt to enter into Section 1031 Exchanges, when possible, to defer some or all of the taxable gains on the sales, if any, for federal and state income tax purposes.

We currently anticipate that, for the remainder of 2023, we could raise up to $200 million of additional capital through our dispositions program. However, any potential future disposition transactions and the timing of any potential future capital recycling transactions will depend on market conditions and other factors, including but not limited to our capital needs, the availability of financing for potential buyers (which has been and may continue to be constrained for some potential buyers due to current economic and market conditions), and our ability to defer some or all of the taxable gains on the sales. In addition, we cannot assure you that we will dispose of any additional properties, or that we will be able to identify and complete the acquisitions of suitable replacement properties to effect Section 1031 Exchanges to defer some or all of the taxable gains related to our capital recycling program. In the event we are unable to complete dispositions as planned, we may raise capital through other sources of liquidity including our available unsecured revolving credit facility, our unsecured term loan facility or the public or private issuance of unsecured debt.

Shelf Registration Statement

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 of its preferred stock, common stock, depository shares and guarantees of debt securities and by the Operating Partnership of its debt securities, in each case 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 of all of these types 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. Capital raising could be more challenging under current market conditions as uncertainty related to interest rates, inflation rates, economic outlook, geopolitical events (including the military conflict between Russia and Ukraine) and other factors have contributed and may continue to contribute to significant volatility and negative pressures in financial markets. 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.

Total Debt, Net	$	4,412,975

________________________ 

(1)As of June 30, 2023, there was no outstanding balance on the unsecured revolving credit facility.

(2)Includes $21.8 million of unamortized deferred financing costs on the unsecured term loan facility, unsecured senior notes and secured debt and $5.8 million of unamortized discounts for the unsecured senior notes. Excludes unamortized deferred financing costs on the unsecured revolving credit facility, which are included in prepaid expenses and other assets, net on our consolidated balance sheets.

On July 20, 2023, certain of our and the Operating Partnership’s subsidiaries entered into a $375.0 million mortgage loan transaction (the “Loan”) secured by, among other things, a deed of trust, assignment of leases and rents, security agreement and fixture filing encumbering two office buildings, 608 apartment units and over 95,000 square feet of retail at the Company’s One Paseo mixed-use campus in Del Mar, California. The Loan matures on August 10, 2034, bears interest at an annual rate of 5.90% and requires monthly interest payments only. In addition, the Operating Partnership has entered into a guaranty in favor of the lender in connection with the Loan. The Loan is generally non-recourse to the Operating Partnership, but the lender has recourse to the Operating Partnership for certain recourse exceptions.

Debt Composition

The composition of the Operating Partnership’s aggregate debt balances between secured and unsecured and fixed-rate and variable-rate debt as of June 30, 2023 and December 31, 2022 was as follows:

	Percentage of Total Debt (1)				Weighted Average Interest Rate (1)

Liquidity Uses

Contractual Obligations

Refer to our 2022 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 six months ended June 30, 2023.

Other Liquidity Uses

Development

The following table summarizes our development spending directly related to our operating, development and redevelopment properties as of June 30, 2023:

Development Phase	Number of Projects	Total Estimated Investment (1)		Total Costs Incurred		Remaining Investment (2)		Remaining Costs  to be Spent in 2023
		(in millions)

________________________

(1)    For redevelopment projects, represents the incremental cost of redevelopment and excludes the existing depreciated basis of the buildings under redevelopment.

(2)    Includes costs related to estimated tenant improvements.

(3)    Represents projects that have reached cold shell condition and are ready for tenant improvements, which may require additional major base building construction before being placed in service.

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 unsecured term loan 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.

Debt Maturities

We believe our conservative leverage, staggered debt maturities, unsecured term loan facility and our unsecured revolving credit facility provide us with financial flexibility and enhance our ability to obtain additional sources of liquidity if necessary, and, therefore, we believe 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. However, we can provide no assurance that we will have access to the public or private debt or equity markets in the future on favorable terms or at all. Excluding our unsecured term loan facility maturing in October 2024, for which we have two twelve-month extension options, our next debt maturity occurs in December 2024. We may, however, repurchase our outstanding debt (including our unsecured senior notes) from time to time prior to maturity (depending on prevailing market conditions, our liquidity, contractual restrictions and other factors) through cash purchases, open-market purchases, privately negotiated transactions, tender offers or otherwise.

46

Potential Future Acquisitions

As discussed in the section “Factors That May Influence Future Results of Operations - Acquisitions,” we continue to evaluate strategic opportunities and remain a disciplined buyer of development and redevelopment opportunities as well as value-add and strategic operating properties, 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, entertainment and professional services. We expect that any material acquisitions will be funded with borrowings under the unsecured revolving credit facility and unsecured term loan 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.

We cannot provide assurance that we will enter into any agreements to acquire properties or undeveloped land, or that potential acquisitions contemplated by any agreements we may enter into in the future will be completed.

Share Repurchases

As of June 30, 2023, 4,935,826 shares remained eligible for repurchase under a share repurchase program approved by the Company’s Board of Directors in 2016. Under this program, repurchases may be made in open market transactions at prevailing prices or through privately negotiated transactions. We may elect to repurchase shares of our common stock under this program in the future depending upon various factors, including market conditions, the trading price of our common stock and our other uses of capital. This program does not have a termination date and repurchases may be discontinued at any time. We intend to fund repurchases, if any, primarily with the proceeds from property dispositions.

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. Additionally, due to the uncertainty around current economic market conditions and companies utilizing hybrid/remote work arrangements, there may be a continued lower level of leasing activity as compared to historical trends.

47

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 macro economy, the state of the credit and equity markets, significant tenant defaults, a decline in the demand for office 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 (including the military conflict between Russia and Ukraine) 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, 2022 for additional information). These events could result in the following:

•Decreases 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. In the event that the Operating Partnership’s credit ratings are downgraded, we may incur higher borrowing costs and may experience difficulty in obtaining additional financing or refinancing existing indebtedness.

Debt Covenants

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. Key existing financial covenants and their covenant levels include:

Unsecured Revolving Credit Facility, Unsecured Term Loan Facility and Private Placement Notes (as defined in the applicable Credit Agreements):	Covenant Level	Actual Performance as of June 30, 2023
Total debt to total asset value	less than 60%	29%
Fixed charge coverage ratio	greater than 1.5x	3.9x
Unsecured debt ratio	greater than 1.67x	3.36x
Unencumbered asset pool debt service coverage	greater than 1.75x	4.48x
Unsecured Senior Notes due 2024, 2025, 2028, 2029, 2030, 2032 and 2033 (as defined in the applicable Indentures):
Total debt to total asset value	less than 60%	37%
Interest coverage	greater than 1.5x	7.7x
Secured debt to total asset value	less than 40%	2%
Unencumbered asset pool value to unsecured debt	greater than 150%	279%

The Operating Partnership was in compliance with all of its debt covenants as of June 30, 2023. Our current expectation is that the Operating Partnership will continue to meet the requirements of its debt 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 Flow Summary

The following summary discussion of our consolidated historical cash flow 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 flow for the periods presented below. Changes in our cash flow include changes in cash and cash equivalents and restricted cash. Our historical cash flow activity for the six months ended June 30, 2023 as compared to the six months ended June 30, 2022 is as follows:

	Six Months Ended June 30,
	2023		2022		Dollar Change		Percentage Change
	($ in thousands)
Net cash provided by operating activities	$	283,550	$	278,949	$	4,601	1.6	%
Net cash used in investing activities	(259,390)		(312,719)		53,329		(17.1)	%
Net cash used in financing activities	(9,654)		(170,261)		160,607		(94.3)	%
Net increase (decrease) in cash and cash equivalents	$	14,506	$	(204,031)	$	218,537	(107.1)	%

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 projects and related financing activities, and other general and administrative costs. Our net cash provided by operating activities increased by $4.6 million, or 1.6%, for the six months ended June 30, 2023 compared to the six months ended June 30, 2022 primarily as result of an increase in cash Net Operating Income generated from stabilized development properties in our Development Portfolio and cash rents received during the six months ended June 30, 2023 from tenants who had free rent and beneficial occupancy periods during the six months ended June 30, 2022 partially offset by net changes in other operating liabilities related to the timing of expenditures. See additional information under the caption “—Results of Operations.”

Investing Activities

Our cash flows from investing activities is generally used to fund development and operating property acquisitions, expenditures for development and redevelopment projects, and recurring and nonrecurring capital expenditures for our operating properties, net of proceeds received from dispositions of real estate assets. During the six months ended June 30, 2023, our net cash used in investing activities decreased by $53.3 million or 17.1% compared the six months ended June 30, 2022 primarily due to the acquisition of a development property during the six months ended June 30, 2022. We did not complete any acquisitions during the six months ended June 30, 2023.

Financing Activities

Our cash flows from financing activities is principally impacted by our capital raising activities, net of dividends and distributions paid to common and preferred security holders. During the six months ended June 30, 2023, our net cash used in financing activities decreased by $160.6 million or 94.3% compared to the six months ended June 30, 2022 primarily as a result of borrowing $150.0 million on the unsecured term loan facility during the six months ended June 30, 2023. We did not draw on any debt facilities during the six months ended June 30, 2022.

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, 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, 2022, 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 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 extraordinary items, as defined by GAAP, gains and losses from sales of depreciable real estate and impairment write-downs associated with depreciable real estate, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs and depreciation of non-real estate assets) and after adjustment for unconsolidated partnerships and joint ventures. 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.

However, FFO should not be viewed as an alternative measure of our operating performance because 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.

The following table presents our FFO for the three and six months ended June 30, 2023 and 2022:

	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
	(in thousands)
Net income available to common stockholders	$	55,587	$	47,105	$	112,195	$	100,233
Adjustments:
Net income attributable to noncontrolling common units of the Operating Partnership	537		515		1,097		1,031
Net income attributable to noncontrolling interests in consolidated property partnerships	5,151		6,355		13,213		12,094
Depreciation and amortization of real estate assets	88,473		94,718		180,144		181,719
Funds From Operations attributable to noncontrolling interests in consolidated property partnerships	(7,895)		(9,340)		(18,837)		(17,958)
Funds From Operations (1)(2)	$	141,853	$	139,353	$	287,812	$	277,119

________________________

(1)    Reported amounts are attributable to common stockholders, common unitholders and restricted stock unitholders.

(2)    FFO available to common stockholders and unitholders includes amortization of deferred revenue related to tenant-funded tenant improvements of $4.9 million for the three months ended June 30, 2023 and 2022, and $10.1 million and $9.2 million for the six months ended June 30, 2023 and 2022, respectively.

PART II – OTHER INFORMATION

ITEM 1.    LEGAL PROCEEDINGS

We and our properties are subject to routine litigation incidental to our business. These matters are generally covered by insurance. As of June 30, 2023, we are not a defendant in, and our properties are not subject to, any legal proceedings that we believe, if determined adversely to us, would have a material adverse effect upon our financial condition, results of operations or cash flows.

ITEM 1A.    RISK FACTORS

There have been no material changes to the risk factors included in the Company’s and the Operating Partnership’s annual report on Form 10-K for the year ended December 31, 2022, other than as set forth below, which supplements the risk factors included in the Company’s and the Operating Partnership’s annual report on Form 10-K for the year ended December 31, 2022.

We could be adversely affected by labor disputes, strikes or other union job actions. If workers providing services at our properties were to engage in a strike or other work stoppage or interruption, our business, results of operations, financial condition and liquidity could be materially adversely affected. Although we believe that our relations with our service providers are good, if disputes with our service providers arise or if workers providing services at our properties engage in a strike or other work stoppage or interruption, we could experience a significant disruption of, or inefficiencies in, our operations or at our properties or incur higher labor costs, which could have a material adverse effect on our business, results of operations,

financial condition and liquidity.

Some of our tenants employ the services of writers, directors, actors and other talent as well as trade employees and others who are subject to collective bargaining agreements in the entertainment industry. If expiring collective bargaining agreements cannot be renewed, then it is possible that the affected unions could take action in the form of strikes or work stoppages. Such actions, including episodic strikes in the entertainment industry, as well as higher costs or operating complexities in connection with these collective bargaining agreements or a significant labor dispute, could have an adverse effect on our tenants’ businesses by causing delays in production, added costs or by reducing profit margins, which in turn could adversely affect our ability to collect rent from those tenants and potentially the markets in which our properties are located.

ITEM 2.     UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

(a) Recent Sales of Unregistered Securities: None.

(b) Use of Proceeds from Registered Securities: None.

(c) Purchases of Equity Securities by the Issuer and Affiliated Purchasers:

Organization and Ownership

Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office, life science and mixed-use submarkets in the United States. We own, develop, acquire and manage real estate assets, consisting primarily of Class A properties in Greater Los Angeles, San Diego County, the San Francisco Bay Area, Greater Seattle and Austin, Texas, which we believe have strategic advantages and strong barriers to entry. Class A real estate encompasses attractive and efficient buildings of high quality that are attractive to tenants, are well-designed and constructed with above-average material, workmanship and finishes and are well-maintained and managed. We qualify 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”). We generally conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context indicates otherwise, the terms “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries 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 properties at June 30, 2023:

	Number of Buildings	Rentable Square Feet	Number of Tenants	Percentage  Occupied (1)		Percentage Leased
Stabilized Office Properties (2)	119	16,214,594	401	86.6	%	88.6	%

(1)Represents economic occupancy.

(2)Includes stabilized life science and retail space.

	Number of Projects	Number of Units	2023 Average Occupancy
Stabilized Residential Properties	3	1,001	93.0	%

Our stabilized portfolio includes all of our properties with the exception of development properties currently committed for construction, under construction, or in the tenant improvement phase, redevelopment properties under construction, undeveloped land and real estate assets held for sale. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs on the existing or acquired buildings pursuant to a formal plan, the intended result of which is a higher economic return on the property. We define properties in the tenant improvement phase as office and life science properties that we are developing or redeveloping where the project has reached cold shell condition and is ready for tenant improvements, which may require additional major base building construction before being placed in service. Projects in the tenant improvement phase are added to 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. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets at the historical cost of the property as the projects or phases of projects are placed in service.

As of June 30, 2023, the following properties were excluded from our stabilized portfolio:

	Number of Properties/Projects	Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement	2	805,000
In-process development projects - under construction	1	875,000
In-process redevelopment projects - under construction	2	100,000

________________________

(1)Estimated rentable square feet upon completion.

We did not have any properties held for sale at June 30, 2023. Our stabilized portfolio also excludes our future development pipeline, which as of June 30, 2023 was comprised of eight future development sites, representing approximately 64 gross acres of undeveloped land.

As of June 30, 2023, all of our properties, development projects and redevelopment projects were owned and all of our business was conducted in the state of California with the exception of ten stabilized office properties and one future development project located in the state of Washington, and one development project in the tenant improvement phase and one future development project in Austin, Texas. All of our properties, development projects and redevelopment projects are 100% owned, excluding four office properties owned by three consolidated property partnerships. Two of the three consolidated property partnerships, 100 First Street Member, LLC (“100 First LLC”) and 303 Second Street Member, LLC (“303 Second LLC”), each owned one office property in San Francisco, California through subsidiary REITs. As of June 30, 2023, the Company owned a 56% common equity interest in both 100 First LLC and 303 Second LLC. The third consolidated property partnership, Redwood City Partners, LLC (“Redwood LLC”) owned two office properties in Redwood City, California. As of June 30, 2023, the Company owned an approximate 93% common equity interest in Redwood LLC. The remaining interests in all three property partnerships were owned by unrelated third parties.

Ownership and Basis of Presentation

The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, 303 Second LLC, 100 First LLC, Redwood LLC and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements.

As of June 30, 2023, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.0% common limited partnership interest in the Operating Partnership as of June 30, 2023 was owned by non-affiliated investors and certain of our executive officers and directors. 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 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, 2023. 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, 2022.

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 June 30, 2023, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At June 30, 2023, the Company and the Operating Partnership were determined to be the primary beneficiaries of these two VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of June 30, 2023, the two VIEs’ total assets, liabilities and noncontrolling interests included on our consolidated balance sheet were approximately $423.0 million (of which $354.7 million related to real estate held for investment), approximately $25.9 million and approximately $175.4 million, respectively. Revenues, income and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures and required distributions.

At December 31, 2022, the consolidated financial statements of the Company included two VIEs in addition to the Operating Partnership: 100 First LLC and 303 Second LLC. At December 31, 2022, the Company and the Operating Partnership were determined to be the primary beneficiaries of these two VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. At December 31, 2022, the impact of consolidating the VIEs increased the Company’s total assets, liabilities and noncontrolling interests on our consolidated balance sheet by approximately $438.7 million (of which $362.7 million related to real estate held for investment), approximately $31.5 million and approximately $179.4 million, respectively.

Secured and Unsecured Debt of the Operating Partnership

Secured and Unsecured Debt of the Operating Partnership

The Company generally guarantees all of the Operating Partnership’s unsecured debt obligations including the unsecured revolving credit facility, the unsecured term loan facility and all of the unsecured senior notes.

Unsecured Revolving Credit Facility and Term Loan Facility

The following table summarizes the balance and terms of our unsecured revolving credit facility as of June 30, 2023 and December 31, 2022:

	June 30, 2023			December 31, 2022
	(in thousands)
Outstanding borrowings	$	—		$	—
Remaining borrowing capacity	1,100,000			1,100,000

Interest rate (2)	6.09		%	5.20		%
Facility fee-annual rate (3)	0.200%
Maturity date (4)	July 31, 2025

________________________

(1)Total borrowing capacity is reduced by the amount of our outstanding letters of credit which total approximately $5.2 million as of the date of this report. We may elect to borrow, subject to bank approval and obtaining commitments for any additional borrowing capacity, up to an additional $500.0 million under an accordion feature under the terms of the unsecured revolving credit facility.

(2)Our unsecured revolving credit facility interest rate was calculated using a contractual rate of Secured Overnight Financing Rate (“SOFR”) plus a SOFR adjustment of 0.10% (“Adjusted SOFR”) and a margin of 0.900% based on our credit rating as of June 30, 2023 and December 31, 2022. 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 facility fee is paid on a quarterly basis and is calculated based on the total borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $4.3 million and $5.3 million of unamortized deferred financing costs, respectively, which are included in prepaid expenses and other assets, net on our consolidated balance sheets, remained to be amortized through the maturity date of our unsecured revolving credit facility.

(4)The maturity date may be extended by two six-month periods, at the Company’s option.

The Company intends to borrow under the unsecured revolving credit facility from time to time for general corporate purposes, to finance development and redevelopment expenditures, to fund potential acquisitions and to potentially repay long-term debt and to supplement cash balances given uncertainties and volatility in market conditions.

In January 2023, the Operating Partnership entered into the first amendment to its existing unsecured term loan facility agreement to (i) exercise the accordion feature under the term loan agreement to provide for $100.0 million of additional term loan commitments and (ii) increase the borrowing capacity under the accordion feature to provide additional term loan commitments or add one or more tranches of term loans up to an aggregate amount of $650.0 million. In March 2023, the Operating Partnership further amended the unsecured term loan facility agreement to exercise the accordion feature to provide for $20.0 million of additional term loan commitments, bringing the total borrowing capacity of the unsecured term loan facility to $520.0 million.

The following table summarizes the balance and terms of our unsecured term loan facility as of June 30, 2023 and December 31, 2022:

	June 30, 2023			December 31, 2022

(2)Our unsecured term loan facility interest rate was calculated using a contractual rate of Adjusted SOFR plus a margin of 0.950% based on our credit rating as of June 30, 2023 and December 31, 2022.

(3)Our undrawn facility fee is paid on a quarterly basis and is calculated based on the remaining borrowing capacity. In addition to the facility fee, we incurred debt origination and legal costs. As of June 30, 2023 and December 31, 2022, $3.8 million and $4.5 million, respectively, of unamortized deferred financing costs remained to be amortized through the maturity date of our unsecured term loan facility.

(4)The maturity date may be extended by two twelve-month periods, at the Company’s option.

Debt Covenants and Restrictions

The unsecured revolving credit facility, unsecured term loan facility, the unsecured senior notes, including the private placement notes, and certain other secured debt arrangements contain covenants and restrictions requiring us to meet certain financial ratios and reporting requirements. Some of the more restrictive financial covenants include a maximum ratio of total debt to total asset value, a minimum fixed-charge coverage ratio, a maximum ratio of secured debt to total asset value, a minimum unsecured debt ratio and a minimum unencumbered asset pool debt service coverage ratio. Noncompliance with one or more of the covenants and restrictions could result in the full principal balance of the associated debt becoming immediately due and payable. We were in compliance with all of our debt covenants as of June 30, 2023.

Noncontrolling Interest [Abstract]

Noncontrolling Interests on the Company's Consolidated Financial Statements

Noncontrolling Interests on the Company’s Consolidated Financial Statements

Common Units of the Operating Partnership

The Company owned an approximate 99.0% common general partnership interest in the Operating Partnership as of June 30, 2023, December 31, 2022 and June 30, 2022. The remaining approximate 1.0% common limited partnership interest as of June 30, 2023, December 31, 2022 and June 30, 2022 was owned by non-affiliated investors and certain of our executive officers and directors in the form of noncontrolling common units. There were 1,150,574 common units outstanding held by these investors, executive officers and directors as of June 30, 2023, December 31, 2022 and June 30, 2022.

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 $34.4 million and $44.7 million as of June 30, 2023 and December 31, 2022, 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 expected in most cases that each common unit would be entitled to a liquidating distribution equal to the liquidating distribution payable in respect of each share of the Company’s common stock.

Share-Based Compensation

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

Stockholder Approved Share-Based Incentive Compensation Plan

As of June 30, 2023, we maintained one share-based incentive compensation plan, the Kilroy Realty 2006 Incentive Award Plan, as amended (the “2006 Plan”). The Company has a currently effective registration statement registering 12.6 million shares of our common stock for possible issuance under our 2006 Plan. As of June 30, 2023, approximately 2.9 million shares were available for grant under the 2006 Plan. The calculation of shares available for grant is presented after taking into account a reserve for a sufficient number of shares to cover the vesting and payment of 2006 Plan awards that were outstanding on that date, including performance-based vesting awards at (i) levels actually achieved for the performance conditions (as defined below) for which the performance period has been completed and (ii) at maximum levels for the other performance and market conditions (as defined below) for awards still in a performance period.

Executive Transitions

On March 30, 2023, our Chief Executive Officer (“CEO”) announced his retirement effective December 31, 2023. Additionally, as previously disclosed, the Company and our former President entered into a separation agreement in 2022 under which he continued to serve as an officer of the Company until the scheduled expiration date of his employment agreement on March 1, 2023.

For our CEO, the vesting of all unvested share-based compensation awards is being accelerated through December 31, 2023 and the final number of any restricted stock units (“RSUs”) subject to market and/or performance-based vesting requirements that vest will be based upon a shortened performance period ending on December 31, 2023. Share-based compensation expense for these awards will be recognized based on our current assumption of the achievement of market and/or performance-based vesting requirements for the shortened performance periods. For our former President, the vesting of all unvested share-based compensation awards was accelerated through March 1, 2023 and the final number of RSUs earned that were subject to market and/or performance-based vesting requirements was based upon the actual achievement of the market and/or performance conditions for a shortened performance period ending on March 1, 2023. For the three and six months ended June 30, 2023, we recognized $5.4 million and $13.2 million, respectively, of stock compensation expense related to the accelerated vesting of awards for our CEO and former President.

2023 Share-Based Compensation Grants

In February 2023, the Executive Compensation Committee of the Company’s Board of Directors awarded 517,066 restricted stock units to certain officers of the Company under the 2006 Plan, which included 300,007 RSUs (at the target level of performance) that are subject to market and/or performance-based vesting requirements (the “2023 Performance-Based RSUs”) and 217,059 RSUs that are subject to time-based vesting requirements (the “2023 Time-Based RSUs”).

2023 Performance-Based RSU Grant

The 2023 Performance-Based RSUs are scheduled to vest at the end of a three year period (consisting of calendar years 2023-2025), except for our CEO, whose RSUs are scheduled to vest on his announced retirement date of December, 31, 2023. A target number of 2023 Performance-Based RSUs were awarded, and the final number of 2023 Performance-Based RSUs that vest (which may be more or less than the target number) will be based upon (1) during the first calendar year of the three year performance measurement period, the achievement of pre-set FFO per share goals that applies to 100% of the Performance-Based RSUs awarded (the “FFO Performance Condition”) and (2) a performance measure that applies to 50% of the award based upon a measure of the Company’s average debt to EBITDA ratio for the three year performance period (the “Debt to EBITDA Ratio Performance Condition”) and a market measure that applies to the other 50% of the award based upon the relative ranking of the Company’s total stockholder return for the three year performance period compared to the total stockholder returns of an established comparison group of companies over the same period (the “Market Condition”). The 2023 Performance-Based RSUs are also subject to a three year service vesting provision (the “service vesting condition”) and are scheduled to cliff vest on the date the final vesting percentage is determined following the end of the three year performance period under the awards. The number of 2023 Performance-Based RSUs ultimately earned could fluctuate from the target number of 2023 Performance-Based RSUs granted based upon the levels of achievement for the FFO Performance Condition, the Debt to EBITDA Ratio Performance Condition, the Market Condition, and the extent to which the service vesting condition

is satisfied. The estimate of the number of 2023 Performance-Based RSUs earned is evaluated quarterly during the performance period based on our estimate for each of the performance conditions measured against the applicable goals.

Compensation expense for the 2023 Performance-Based RSU grant is recognized on a straight-line basis over the requisite service period for each participant, which is generally the three year service period, except for our CEO, whose compensation expense is recognized on an accelerated basis through his announced retirement date of December 31, 2023. During the six months ended June 30, 2023, we recognized $4.2 million of compensation expense for the 2023 Performance-Based RSU grant assuming the 2023 FFO Performance Condition is met at 111% of the target level of achievement (116.5% for our CEO) and the 2023 Debt to EBITDA Ratio Performance Condition is met at 100% of the target level of achievement (175.0% for our CEO). In the event we achieve a lower level of performance or fail to meet the FFO performance condition, we would reverse a portion or all of the $4.2 million of compensation expense.

Each 2023 Performance-Based RSU represents the right to receive one share of our common stock in the future, subject to, and as modified by the Company’s level of achievement of the applicable performance and market conditions. The fair value of the portion of the award subject to the Debt to EBITDA Ratio Performance Condition was calculated using the closing price of the Company’s common stock on the valuation date noted below. The fair value of the portion of the award subject to the Market Condition was calculated using a Monte Carlo simulation pricing model based on the assumptions in the table below, which resulted in the following grant date fair value per share.

	Fair Value Assumptions
Valuation date	February 6, 2023
Fair value per share on valuation date (1)	$40.10
Expected share price volatility	35.0%
Risk-free interest rate	4.12%

________________________ 

(1)For one participant, the fair value per share on the valuation date for their 2023 Performance-Based RSUs is $40.43.

The computation of expected volatility was based on a blend of the historical volatility of our shares of common stock over a period of twice the remaining performance period as of the grant date and implied volatility data based on the observed pricing of six month publicly-traded options on shares of our common stock. The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury STRIP securities in effect at February 6, 2023.

The fair value of the 2023 Performance-Based RSU grant as of the valuation date noted above, based on a target level of achievement, was $12.0 million. For the three and six months ended June 30, 2023, we recorded compensation expense based upon the grant date fair value per share for each component multiplied by the estimated number of RSUs to be earned.

2023 Time-Based RSU Grant

The 2023 Time-Based RSUs are scheduled to vest in three equal annual installments beginning on January 5, 2024 through January 5, 2026. Compensation expense for the 2023 Time-Based RSUs is recognized on a straight-line basis over the requisite service period, which is generally the explicit service period except for our CEO, whose compensation expense is recognized on an accelerated basis through his announced retirement date of December 31, 2023. Each 2023 Time-Based RSU represents the right to receive one share of our common stock in the future, subject to continued employment through the applicable vesting date, unless accelerated upon separation of employment, provided certain conditions are met. The total grant date fair value of the 2023 Time-Based RSU awards was $8.6 million, which was based on the $39.65 closing share price of the Company’s common stock on the NYSE on the February 6, 2023 grant date.

2022 and 2021 Performance-Based RSUs

Compensation cost for the 2022 performance-based RSUs for the three and six months ended June 30, 2023 assumes the 2022 Debt to EBITDA Ratio Performance Condition is met at 150% of the target level of achievement (175.0% for our CEO). Compensation cost for the 2021 performance-based RSUs for the three and six months ended June 30, 2023 assumes the 2021 Debt to EBITDA Ratio Performance Condition is met at 150% of the target level of achievement (175.0% for our CEO).

Share-Based Compensation Cost Recorded During the Period

The total compensation cost for all share-based compensation programs was $9.5 million and $9.7 million for the three months ended June 30, 2023 and 2022, respectively, and $21.0 million and $16.3 million for the six months ended June 30, 2023 and 2022, respectively. Share-based compensation costs for the three and six months ended June 30, 2023 include $5.4 million and $13.2 million, respectively, of accelerated share-based compensation costs for our CEO and former President as discussed above. Of the total share-based compensation costs, $1.8 million and $3.3 million was capitalized as part of the real estate assets for the three and six months ended June 30, 2023, respectively, and $1.7 million and $3.0 million was capitalized as part of the real estate assets for the three and six months ended June 30, 2022, respectively. As of June 30, 2023, there was approximately $34.1 million of total unrecognized compensation cost related to nonvested RSUs granted under share-based compensation arrangements. Such amount is based in part upon the estimated future outcome of the performance metrics as of June 30, 2023, and the actual compensation cost ultimately recognized could increase or decrease from this estimate based upon actual performance results. These costs are expected to be recognized over a weighted-average period of 1.3 years, which includes the shortened vesting period for our CEO due to his announced retirement on December 31, 2023. The remaining compensation cost related to these nonvested RSU awards had been recognized in periods prior to June 30, 2023.
