Kilroy Realty Corporation (NYSE:KRC) ("Kilroy" or the "Company") today reported financial results for the first quarter ended March 31, 2026.

"I am pleased to report on a remarkably strong quarter of execution across all facets of our business. First-quarter leasing activity, which totaled 568,000 square feet, represented the Company's strongest first-quarter performance since 2017, as we continued to capitalize on accelerating momentum across the West Coast," said Angela Aman, Chief Executive Officer. "In addition, we remained active on the capital allocation front, selling approximately $350 million of non-core and non-strategic properties year-to-date, while prudently allocating capital to debt repayments, opportunistic share repurchases, and a substantially pre-leased development project in one of the Company's best-performing submarkets."

(1)	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 depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. The reconciling items include amounts to adjust earnings from consolidated partially-owned entities and equity in earnings of unconsolidated affiliates to FFO. Our calculation of FFO includes the amortization of deferred revenue related to tenant-funded tenant improvements and excludes the depreciation of the related tenant improvement assets. We also add back net income attributable to noncontrolling common units of the Operating Partnership because we report FFO attributable to common stockholders and common unitholders.

	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.

	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.
(2)	Reported amounts are attributable to common stockholders, common unitholders, and restricted stock unitholders.
(3)	FFO available to common stockholders and unitholders includes amortization of deferred revenue related to tenant-funded tenant improvements of $3.2 million and $3.7 million for the three months ended March 31, 2026 and 2025, respectively.
(4)	Calculated based on weighted average shares outstanding, including participating share-based awards (i.e., certain time-based restricted stock units) and assuming the exchange of all common limited partnership units outstanding.
(5)	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.
