Curbline Properties Corp.

Nature of Business and Financial Statement Presentation

Nature of Business

Curbline Properties Corp., a Maryland corporation, and its consolidated subsidiaries (collectively, the “Company” or “Curbline”) are primarily engaged in the business of owning, leasing, acquiring, and managing convenience shopping centers positioned on the curbline of well-trafficked intersections and major vehicular corridors in suburban, high household income communities. Curbline Properties LP (the “Operating Partnership”) is a Delaware limited partnership formed to serve as Curbline’s majority-owned partnership subsidiary and to own, through affiliates, all of our real estate properties and assets. The Operating Partnership’s capital includes common general and limited partnership interests in the operating partnership (“Common Units”) and LTIP Units, as described in Note 9 (together with the Common Units, the “OP Units”). As of March 31, 2026, Curbline held an approximately 99.0% ownership interest in the Operating Partnership, with the remaining OP Units held by members of management. Unless otherwise provided, references herein to the Company or Curbline include Curbline Properties Corp. and Curbline Properties LP and their consolidated subsidiaries. The Company’s tenant base includes a mixture of national, regional and local retail tenants. Consequently, the Company’s credit risk is primarily concentrated in the retail industry. As of March 31, 2026, the Company owned 190 convenience shopping centers consisting of 5.0 million square feet of gross leasable area (“GLA”).

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates.

Unaudited Interim Financial Statements

These financial statements have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three months ended March 31, 2026 and 2025, are not necessarily indicative of the results that may be expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Principles of Consolidation

The consolidated financial statements include the results of the Company, the Operating Partnership and their consolidated subsidiaries. Interests in the Operating Partnership not owned by the Company are referred to as non-controlling interests. These non-controlling interests are held by members of management in the form of LTIP Units issued pursuant to the Company’s 2024 Equity and Incentive Compensation Plan. All significant intercompany balances and transactions have been eliminated in consolidation.

Statementsof Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information

Non-cash investing and financing activities are summarized as follows (in millions):

Non-Controlling Interests

Non-controlling interests in the Operating Partnership include limited partnership interests in the Operating Partnership in the form of Common Units and LTIP Unit awards classified as equity. Net income allocated to the non-controlling interests related to the Common Units and service-based LTIP Units is based on the weighted-average ownership during the period. The Company will adjust the carrying value of the non-controlling interests to reflect its share of the book value of the Operating Partnership when there has been a change in the Company’s ownership of the Operating Partnership. Such adjustments will be recorded to additional paid-in capital as a rebalancing of non-controlling interests on the accompanying consolidated statements of equity.

Segments

The Company has asingle operating segment. The Company’s convenience shopping centers have common characteristics and are managed on a consolidated basis. The Company does not differentiate among properties on a geographical basis or any other basis for purposes of allocating resources or capital. The Company’s Chief Operating Decision Maker (“CODM”) may review operational and financial data on an ad-hoc basis at a property level.

The Company’s CODM is thechief executive officer. The CODM assesses performance for the segment and decides how to allocate resources based on net income as reported in the consolidated statements of operations. In addition, the CODM usesnet operating income (“NOI”) as a supplemental measure to evaluate and assess the performance of the Company’s operating portfolio. The Company defines NOI as property revenues less property-related expenses and excludes depreciation and amortization expense, interest income and expense, and corporate level transactions. The CODM reviews significant expenses associated with the Company’s single operating segment which are presented in the consolidated statements of operations. The CODM uses net income and NOI to evaluate income generated from the Company’s shopping centers in deciding whether to reinvest or allocate profits to capital expenditures, acquisitions or dividends. Net income and NOI are also used to monitor budget versus actual results in assessing the performance of the Company’s properties. The measure of segment assets is reported in the consolidated balance sheets as total consolidated assets.

Equity

In February 2026, the Company completed a follow-on primary offering of 9,200,000 shares of its common stock on a forward basis, including the full exercise of the underwriters’ option to purchase up to 1,200,000 additional shares of common stock, at a public offering price of $25.50 per share for expected gross proceeds of $234.6 million before deducting underwriting discounts and expenses. No shares under these forward agreements have been physically settled as of March 31, 2026. The Company is required to settle these shares by August 2027.

During the first quarter of 2026, the Company offered and sold 2,038,800 shares of its common stock on a forward basis under the at-the-market equity program (“ATM Program”) at a weighted-average price of $23.36 per share before issuance costs and expenses, generating expected estimated gross proceeds before issuance costs of $47.6 million. The Company is required to settle these shares by March 31, 2027. As of March 31, 2026, the Company had unsettled outstanding forward shares of $123.1 million under the ATM Program and $126.9 million of remaining capacity under the ATM Program.

Recently Issued Accounting Standards

Expense Disaggregation Disclosures. In November 2024, the FASB issued ASU 2024-03, which requires additional disaggregated disclosure about certain income statement expense line items. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim periods within the fiscal years beginning after December 15, 2027.

The 2024 Term Loan, 2025 Term Loan and the Revolving Credit Facility also contain customary default provisions including, among other things, the failure to make timely payments of principal and interest payable thereunder and the failure of the Company or its subsidiaries to pay, when due, certain indebtedness in excess of certain thresholds beyond applicable grace and cure periods. The Company was in compliance with these financial covenants at March 31, 2026.

Financial Instruments and Fair Value Measurements

The following methods and assumptions were used by the Company in estimating fair value disclosures of financial instruments:

Cash and Cash Equivalents, Accounts Receivable and Accounts Payable and Other Liabilities

The carrying amounts reported in the Company’s consolidated balance sheets for these financial instruments approximated fair value because of their short-term maturities.

The fair market value of debt is estimated using a discounted cash flow technique that incorporates future contractual interest and principal payments and a market interest yield curve with adjustments for duration, optionality and risk profile, including the Company’s non-performance risk and loan to value, and is classified as Level 3 in the fair value hierarchy.

Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented are not necessarily indicative of the amounts the Company could realize on disposition of the financial instruments. At March 31, 2026 and December 31, 2025, the carrying amount of indebtedness was $595.5 million and $423.2 million, respectively, and the fair value was $599.1 million and $432.0 million, respectively.

Items Measured on Fair Value on a Recurring Basis - Derivatives

The Company has pay-fixed interest rate swaps to manage some of its exposure to future changes in benchmark-interest rates (the “Swaps”). The estimated fair value was determined using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contract, are incorporated in the fair value to account for potential non-performance risk, including the Company’s own non-performance risk and the respective counterparty’s non-performance risk. The Company determined that the significant inputs used to value its Swaps fell within Level 2 of the fair value hierarchy.

The following table summarizes the terms and fair value of the Company’s derivative financial instruments (in thousands):

(A)

These interest rate swap agreements utilize a one-month SOFR.

(B)

The Swaps (included in accounts payable and other liabilities) are measured at fair value on a recurring basis, which are classified as Level 2 measurement on the fair value hierarchy.

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its debt funding and, from time to time, through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the values of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s borrowings.

Cash Flow Hedges of Interest Rate Risk

The Company’s objectives in using interest rate derivatives are to manage its exposure to interest rate movements. To accomplish this objective, the Company generally uses swaps, caps and treasury locks as part of its interest rate risk management strategy. The Swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated, and that qualify, as cash flow hedges are recorded in Accumulated Other Comprehensive Income (“OCI”) and are subsequently reclassified into interest expense, in the period that the hedged forecasted transaction affects earnings. The Company expects to reflect, within the next 12 months, an increase to interest expense (and a corresponding decrease to earnings) of approximately $0.3 million. All components of the Swaps were included in the assessment of hedge effectiveness.

The Company is exposed to credit risk in the event of non-performance by the counterparty to the swap if the derivative position has a positive balance. The Company believes it mitigates its credit risk by entering into swaps with major financial institutions. The Company continually monitors and actively manages interest costs on its variable-rate debt portfolio and may enter into additional interest rate swap positions or other derivative interest rate instruments based on market conditions. The Company has not entered, and does not plan to enter, into any derivative financial instruments for trading or speculative purposes.

The table below details the location in the financial statements of the income recognized on interest rate swaps and treasury locks designated as cash flow hedges (in thousands):

Credit Risk-Related Contingent Features

The Company has agreements with Swap counterparties that contain a provision whereby if the Company defaults on certain of its indebtedness, the Company could also be declared in default on the Swap, resulting in an acceleration of payment under the Swap.

Commitments and Contingencies

Legal Matters

The Company and its subsidiaries are subject to various legal proceedings, which, taken together, are not expected to have a material adverse effect on the Company. The Company is also subject to a variety of legal actions for personal injury or property damage arising in the ordinary course of its business, most of which are covered by insurance. While the resolution of all matters cannot be predicted with certainty, management believes that the final outcome of such legal proceedings and claims will not have a material adverse effect on the Company’s liquidity, financial position or results of operations.

Commitments and Guarantees

The Company routinely enters into contracts for the maintenance of its properties. These contracts typically can be canceled upon 30 to 60 days’ notice without penalty. At March 31, 2026, the Company had purchase order obligations, typically payable within one year, aggregating approximately $1.6 million related to the maintenance of its properties and general and administrative expenses.

Accumulated Other Comprehensive Income (Loss)

The changes in Accumulated OCI by component are as follows (in thousands):

Stock-Based Compensation and Employee Benefits

Restricted Stock

On February 22, 2025, the Company granted a total of 30,924 shares of service-based restricted stock to its executive officers and other employees with an aggregate value of $0.8 million, which will vest ratably over a four-year period with the first vesting date being February 22, 2026, subject to the continued employment of the applicable executive officer or employee. The awards to the executive officers were made pursuant to their respective employment agreements.

On February 22, 2026, the Company granted a total of 39,472 shares of service-based restricted stock to its executive officers and other employees with an aggregate value of $1.1 million, which will vest ratably over a four-year period with the first vesting date being February 22, 2027, subject to the continued employment of the applicable executive officer or employee. The awards to the executive officers were made pursuant to their respective employment agreements.

LTIP Units

LTIP Units represent limited partnership units in the Operating Partnership, an entity through which the Company conducts its business, and are structured to qualify as “profits interests” for federal income tax purposes. Awards of LTIP Units shall be valued by reference to our common stock. When issued, LTIP Units do not have full parity, on a per unit basis, with the Common Units. To the extent they receive sufficient allocations of book gain for tax purposes, the LTIP Units can over time achieve full parity with Common Units, at which time vested LTIP Units will be converted into Common Units on a one-for-one basis. Vested LTIP Units that have not achieved full parity with Common Units may also convert into Common Units on a less than a one-for-one basis based on relative capital accounts. Regular and other non-liquidating distributions will be made by the Operating Partnership with respect to unvested LTIP Units as provided in the applicable award agreement for such units. Each Common Unit acquired upon conversion of a vested LTIP Unit may be presented, at the election of the holder, for redemption for cash equal to the market price of a share of common stock of the Company, except that the Company may, at its election, acquire each Common Unit so presented for one share of common stock, subject to certain adjustments. Generally, LTIP Units entitle the holder to receive distributions from the Operating Partnership that are equivalent to the dividends and distributions that would be made with respect to the number of shares of common stock underlying such LTIP Units, though receipt of such distributions may be delayed or made contingent on vesting.

On February 22, 2025, the CEO was granted service-based LTIP Units pursuant to his employment agreement with a value of $0.8 million, which equated to 32,391 LTIP Units, which will vest ratably over athree-year period with the first vesting date being February 22, 2026, subject to his continued employment. On February 22, 2026, the CEO and an executive officer were granted service-based LTIP Units pursuant to their employment agreements with a value of $3.3 million and $0.2 million, respectively, which equated to 122,373 LTIP Units and 5,740 LTIP Units, respectively, which will vest ratably over athree-year period andfour-year period, respectively, with the first vesting date being February 22, 2027, subject to their continued employment. The grant values were equal to the market value of the Company’s common stock at the dates of the grants.

Non-Cash Compensation Expense

The amounts recorded in general and administrative expenses in the Company’s consolidated statements of operations for the amortization of all of the outstanding stock-based awards and LTIP Units for thethree month periods ended March 31, 2026 and 2025, consisted of the following (in thousands):

Earnings Per Share

The Company declared a quarterly cash dividend of $0.17 per share of common stock and $0.16 per share of common stock for the first quarter of 2026 and 2025, respectively.

The following table provides a reconciliation of net income and the number of shares of common stock used in the computations of “basic” earnings per share (“EPS”), which utilizes the weighted-average number of shares of common stock outstanding without regard to potentially dilutive shares of common stock, and “diluted” EPS, which includes all such shares (in thousands, except per share amounts).

Basic average shares outstanding do not include RSUs totaling 0.5 million and RSAs totaling 0.1 million that were not vested at March 31, 2026. Basic average shares outstanding do not include RSUs totaling 0.8 million and RSAs totaling 0.1 million that were not vested at March 31, 2025. Dividends are paid on the outstanding RSUs and RSAs, which makes these shares participating securities.

PRSAs and PB LTIPs issued to certain executives were considered dilutive and are included in the computation of diluted EPS for the three month periods ended March 31, 2026 and 2025.

The agreements to offer and sell shares on a forward basis for approximately 14.5 million common shares were considered in the computation of diluted EPS for the three month period ended March 31, 2026. These agreements were not outstanding at March 31, 2025.

Agreements and Transactions with SITE Centers

On October 1, 2024, Curbline, the Operating Partnership and SITE Centers Corp. (“SITE Centers”) entered into a Separation and Distribution Agreement (the “Separation and Distribution Agreement”), pursuant to which, among other things, SITE Centers transferred its portfolio of convenience shopping centers, $800.0 million of unrestricted cash and certain other assets, liabilities and obligations to Curbline and effected a pro rata special distribution of all of the outstanding shares of Curbline common stock to common shareholders of SITE Centers as of September 23, 2024 (the “Spin-Off”).

To govern certain ongoing relationships between the Company, the Operating Partnership and SITE Centers after the Spin-Off, and to provide for the allocation among the Company, the Operating Partnership and SITE Centers of SITE Centers’ assets, liabilities and obligations attributable to periods both prior to and following the separation of the Company and the Operating Partnership from SITE Centers, the Company, the Operating Partnership and SITE Centers entered into agreements pursuant to which certain services and rights are provided following the Spin-Off, and the Company, the Operating Partnership and SITE Centers will indemnify each other against certain liabilities arising from their respective businesses. The Separation and Distribution Agreement, as well as the Tax Matters Agreement, the Employee Matters Agreement, the Shared Services Agreement and other agreements governing ongoing relationships were negotiated between related parties and their terms, including fees and other amounts payable, may not be on the same terms as if they had been negotiated at arm’s length with an unaffiliated third party.

Separation and Distribution Agreement

The Separation and Distribution Agreement contains obligations for SITE Centers to complete certain redevelopment projects at properties that are owned by the Company. At March 31, 2026 and December 31, 2025, the remaining amount, which is recorded in amounts receivable from SITE Centers in the consolidated balance sheets, was $15.2 million and $20.7 million, respectively.

Shared Services Agreement

For the three months ended March 31, 2026 and 2025, the Company expensed $1.1 million and $0.7 million, respectively, of fees to SITE Centers, which are included in general and administrative expense on the consolidated statements of operations, related to the Shared Services Agreement and are equal to 2% of Curbline’s Gross Revenue (as defined in the Shared Services Agreement). The fair value of the services received by the Company, which was in excess of the fee paid and the fair value of the services provided to SITE Centers, is reflected as an additional expense within general and administrative expense and income within other income (expense), net in the consolidated statements of operations which amou nted to $1.8 million and $0.6 million for the three months ended March 31, 2026 and 2025. Amounts payable to SITE Centers (included in accounts payable and other liabilities on the consolidated balance sheets) as of March 31, 2026 and December 31, 2025 aggregated $0.4 million and $0.9 million, respectively.

Pursuant to the Shared Services Agreement, Curbline has the right to use SITE Centers’ office space, including the location in New York. This arrangement is considered an embedded lease based on the criteria specified in Topic 842. The amount recorded under the Shared Services Agreement is variable and the embedded lease rent expense of$0.4 million is included in general and administrative expense on the consolidated statements of operations for both of the three month periods ended March 31, 2026 and 2025.

Lease Agreements

In October 2024, the Company entered into a lease agreement with SITE Centers under the Separation and Distribution Agreement where SITE Centers leased a portion of a property for one year beginning on April 1, 2025. SITE Centers paid annual rents of $0.8 million as well as a proportionate share of real estate tax expense. The amount received under the lease for the three months ended March 31, 2026 was $0.2 million.

Under the Shared Services Agreement, the Company has the option to lease a portion of the SITE Centers’ Beachwood headquarters. At the time of the separation, the Company recorded a $1.2 million below-market lease (as lessee) for which no amortization of this amount will occur until the option is exercised.

Subsequent Events

Through April 29, 2026, the Company acquired eight convenience shopping centers for an aggregate purchase price of $93.8 million.

In April 2026, the Company offered and sold 514,600 shares of its common stock on a forward basis under the ATM Program at a weighted-average price of $26.06 per share before issuance costs and expenses, generating expected gross proceeds before issuance costs of $13.4 million, with no shares settled to date.
