This Supplemental Financial Report contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements include, among other things, information concerning lease expirations, debt maturities, potential investments, development and redevelopment activity, projected construction costs, dispositions and other forward-looking financial data. In some instances, forward-looking statements can be identified by the use of forward-looking terminology such as “expect,” “future,” “will,” “would,” “pursue,” or “project” and variations of such words and similar expressions that do not relate to historical matters. Forward-looking statements are based on Kilroy Realty Corporation’s current expectations, beliefs and assumptions, and are not guarantees of future performance. Forward-looking statements are inherently subject to uncertainties, risks, changes in circumstances, trends and factors that are difficult to predict, many of which are outside of Kilroy Realty Corporation’s control. Accordingly, actual performance, results and events may vary materially from those indicated or implied in the forward-looking statements, and you should not rely on the forward-looking statements as predictions of future performance, results or events. Numerous factors could cause actual future performance, results and events to differ materially from those indicated in the forward-looking statements, including, among others: global market and general economic conditions, including periods of heightened inflation, and their effect on our liquidity and financial conditions and those of our tenants; adverse economic or real estate conditions generally, and specifically, in the States of California, Texas and Washington; risks associated with our investment in real estate assets, which are illiquid, and with trends in the real estate industry; defaults on or non-renewal of leases by tenants; any significant downturn in tenants’ businesses, including bankruptcy, lack of liquidity or lack of funding and the impact labor disruptions or strikes, such as episodic strikes in the entertainment industry, may have on our tenants’ businesses; our ability to re-lease property at or above current market rates; reduced demand for office space, including as a result of remote working and flexible working arrangements that allow work from remote locations other than an employer's office premises; costs to comply with government regulations, including environmental remediation; the availability of cash for distribution and debt service and exposure to risk of default under debt obligations; increases in interest rates and our ability to manage interest rate exposure; changes in interest rates and the availability of financing on attractive terms or at all, which may adversely impact our future interest expense and our ability to pursue development, redevelopment and acquisition opportunities and refinance existing debt; a decline in real estate asset valuations, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing, and which may result in write-offs or impairment charges; significant competition, which may decrease the occupancy and rental rates of properties; potential losses that may not be covered by insurance; the ability to successfully complete acquisitions and dispositions on announced terms; the ability to successfully operate acquired, developed and redeveloped properties; the ability to successfully complete development and redevelopment projects on schedule and within budgeted amounts; delays or refusals in obtaining all necessary zoning, land use and other required entitlements, governmental permits and authorizations for our development and redevelopment properties; increases in anticipated capital expenditures, tenant improvement and/or leasing costs; defaults on leases for land on which some of our properties are located; adverse changes to, or enactment or implementations of, tax laws or other applicable laws, regulations or legislation, as well as business and consumer reactions to such changes; risks associated with joint venture investments, including our lack of sole decision-making authority, our reliance on co-venturers' financial condition and disputes between us and our co-venturers; environmental uncertainties and risks related to natural disasters; and our ability to maintain our status as a REIT. These factors are not exhaustive and additional factors could adversely affect our business and financial performance. For a discussion of additional factors that could materially adversely affect Kilroy Realty Corporation’s business and financial performance, see the factors included under the caption “Risk Factors” in Kilroy Realty Corporation’s annual report on Form 10-K for the year ended December 31, 2022, and its other filings with the Securities and Exchange Commission. All forward-looking statements are based on currently available information and speak only as of the dates on which they are made. Kilroy Realty Corporation assumes no obligation to update any forward-looking statement made in this Supplemental Financial Report that becomes untrue because of subsequent events, new information or otherwise, except to the extent we are required to do so in connection with our ongoing requirements under federal securities laws.

(1)Calculated based on estimated weighted average shares outstanding including non-participating share-based awards.

(2)See pages 32-33 for Management Statements on Funds From Operations and Same Store Cash Net Operating Income.

(3)Calculated based on weighted average shares outstanding including participating and non-participating share-based awards, dilutive impact of contingently issuable shares, and assuming the exchange of all common limited partnership units outstanding. Reported amounts are attributable to common stockholders, common unitholders and restricted stock unitholders.

(4)Remaining 2023 development spending is $250 million to $300 million.

The Company’s guidance estimates for the full year 2023, and the reconciliation of net income available to common stockholders per share - diluted and FFO per share and unit - diluted included within this report, reflect management’s views on current and future market conditions, including assumptions with respect to rental rates, occupancy levels, and the earnings impact of the events referenced in this report. Although these guidance estimates reflect the impact on the Company’s operating results of an assumed range of future disposition activity, these guidance estimates do not include any estimates of possible future gains or losses from possible future dispositions because the magnitude of gains or losses on sales of depreciable operating properties, if any, will depend on the sales price and depreciated cost basis of the disposed assets at the time of disposition, information that is not known at the time the Company provides guidance, and the timing of any gain recognition will depend on the closing of the dispositions, information that is also not known at the time the Company provides guidance and may occur after the relevant guidance period. We caution you not to place undue reliance on our assumed range of future disposition activity because any potential future disposition transactions will ultimately depend on the market conditions and other factors, including but not limited to the Company’s capital needs, the particular assets being sold and the Company’s ability to defer some or all of the taxable gain on the sales. These guidance estimates also do not include the impact on operating results from potential future acquisitions, possible capital markets activity, possible future impairment charges or any events outside of the Company’s control. There can be no assurance that the Company’s actual results will not differ materially from these estimates.

Non-GAAP Supplemental

Measures

Q2 2023 Supplemental Financial Report

Management Statements on Non-GAAP Supplemental Measures

Included in this section are management’s statements regarding certain non-GAAP financial measures provided in this supplemental financial report and, with respect to Funds From Operations available to common stockholders and common unitholders (“FFO”), in the Company’s earnings release on July 31, 2023 and the reasons why management believes that these measures provide useful information to investors about the Company’s financial condition and results of operations.

Net Operating Income:

Management believes that Net Operating Income (“NOI”) is a useful supplemental measure of the Company’s operating performance. The Company defines NOI as follows: consolidated operating revenues (rental income and other property income) less consolidated property and related expenses (property expenses, real estate taxes and ground leases). Other real estate investment trusts (“REITs”) may use different methodologies for calculating NOI, and accordingly, the Company’s NOI may not be comparable to other REITs.

Because NOI excludes leasing costs, general and administrative expenses, interest expense, depreciation and amortization, other nonproperty income and losses, and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, reflects the consolidated revenues and expenses directly associated with owning and operating commercial real estate and the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing a perspective on operations not immediately apparent from net income. The Company uses NOI to evaluate its operating performance on a portfolio basis since NOI allows the Company to evaluate the impact that factors such as occupancy levels, lease structure, rental rates, and tenant base have on the Company’s results, margins and returns. In addition, management believes that NOI provides useful information to the investment community about the Company’s financial and operating performance when compared to other REITs since NOI is generally recognized as a standard measure of performance in the real estate industry.

However, NOI should not be viewed as an alternative measure of the Company’s financial performance since it does not reflect general and administrative expenses, leasing costs, interest expense, depreciation and amortization costs, other nonproperty income and losses and the level of capital expenditures necessary to maintain the operating performance of the Company’s properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact the Company’s results from operations.

Same Store Net Operating Income:

Management believes that Same Store NOI is a useful supplemental measure of the Company’s operating performance. Same Store NOI represents the consolidated NOI for all of the properties that were owned and included in the Company's stabilized portfolio for two comparable reporting periods. Because Same Store NOI excludes the change in NOI from developed, redeveloped, acquired and disposed of and held for sale properties, it highlights operating trends such as occupancy levels, rental rates and operating costs on properties. Other REITs may use different methodologies for calculating Same Store NOI, and accordingly, the Company’s Same Store NOI may not be comparable to other REITs.

However, Same Store NOI should not be viewed as an alternative measure of the Company’s financial performance since it does not reflect the operations of the Company’s entire portfolio, nor does it reflect the impact of general and administrative expenses, leasing costs, interest expense, depreciation and amortization costs, other nonproperty income and losses and the level of capital expenditures necessary to maintain the operating performance of the Company’s properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact the Company’s results from operations.

Q2 2023 Supplemental Financial Report

Management Statements on Non-GAAP Supplemental Measures, continued

Same Store Cash Net Operating Income:

Management believes that Same Store Cash NOI is a useful supplemental measure of the Company’s operating performance. Same Store Cash NOI represents the consolidated NOI for all of the properties that were owned and included in the Company’s stabilized portfolio for two comparable reporting periods, adjusted for the net effect of straight-line rents, amortization of deferred revenue related to tenant-funded tenant improvements, amortization of above and below market lease intangibles, and the provision for bad debts. Because Same Store Cash NOI excludes the change in NOI from developed, redeveloped, acquired and disposed of and held for sale properties, it highlights operating trends on a cash basis such as occupancy levels, rental rates and operating costs on properties. Other REITs may use different methodologies for calculating Same Store Cash NOI, and accordingly, our Same Store Cash NOI may not be comparable to other REITs.

However, Same Store Cash NOI should not be viewed as an alternative measure of the Company’s financial performance since it does not reflect the operations of the Company's entire portfolio, nor does it reflect the impact of general and administrative expenses, acquisition-related expenses, interest expense, depreciation and amortization costs, other nonproperty income and losses, the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company's properties, or trends in development and construction activities which are significant economic costs and activities that could materially impact the Company's results from operations.

EBITDA, as adjusted:

Management believes that consolidated earnings before interest expense, depreciation and amortization, gain/loss on early extinguishment of debt, gains and losses on depreciable real estate, net income attributable to noncontrolling interests, preferred dividends and distributions, original issuance costs of redeemed preferred stock and preferred units, and impairment losses (“EBITDA, as adjusted”) is a useful supplemental measure of the Company’s operating performance. When considered with other GAAP measures and FFO, management believes EBITDA, as adjusted, gives the investment community a more complete understanding of the Company’s consolidated operating results, including the impact of general and administrative expenses and acquisition-related expenses, before the impact of investing and financing transactions and facilitates comparisons with competitors. Management also believes it is appropriate to present EBITDA, as adjusted, as it is used in several of the Company’s financial covenants for both its secured and unsecured debt. However, EBITDA, as adjusted, should not be viewed as an alternative measure of the Company’s operating performance since it excludes financing costs as well as depreciation and amortization costs which are significant economic costs that could materially impact the Company’s results of operations and liquidity. Other REITs may use different methodologies for calculating EBITDA, as adjusted, and, accordingly, the Company’s EBITDA, as adjusted, may not be comparable to other REITs. The Company’s calculation of EBITDA, as adjusted, is the same as EBITDAre, as defined by Nareit, as the Company does not have any unconsolidated joint ventures.

Q2 2023 Supplemental Financial Report

Management Statements on Non-GAAP Supplemental Measures, continued

Funds From Operations:

The Company calculates Funds From Operations available to common stockholders and common unitholders (“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.

Management believes that FFO is a useful supplemental measure of the Company’s 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 the Company’s 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, the Company’s 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, management believes that FFO along with the required GAAP presentations provides a more complete measurement of the Company’s performance relative to its 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 the Company’s operating performance since it does not reflect either depreciation and amortization costs or the level of capital expenditures and leasing costs necessary to maintain the operating performance of the Company’s properties, which are significant economic costs and could materially impact the Company’s results from operations.

Funds Available for Distribution:

Management believes that Funds Available for Distribution available to common stockholders and common unitholders (“FAD”) is a useful supplemental measure of the Company’s liquidity. The Company computes FAD by adding to FFO the non-cash amortization of deferred financing costs, debt discounts and premiums and share-based compensation awards, amortization of above (below) market rents for acquisition properties and non-cash executive compensation expense then subtracting recurring tenant improvements, leasing commissions and capital expenditures and eliminating the net effect of straight-line rents, amortization of deferred revenue related to tenant improvements, adjusting for other lease related items and amounts of gain or loss on marketable securities related to the Company’s executive deferred compensation plan that are capitalized as development costs, and after adjustment for amounts attributable to noncontrolling interests in consolidated property partnerships. FAD provides an additional perspective on the Company’s ability to fund cash needs and make distributions to stockholders by adjusting FFO for the impact of certain cash and non-cash items, as well as adjusting FFO for recurring capital expenditures and leasing costs. Management also believes that FAD provides useful information to the investment community about the Company’s financial position as compared to other REITs since FAD is a liquidity measure used by other REITs. However, other REITs may use different methodologies for calculating FAD and, accordingly, the Company’s FAD may not be comparable to other REITs.
