Accounting Policies [Abstract] |
Nature of Business | 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 June 30, 2026, Curbline held an approxim ately 99.1% 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 June 30, 2026, the Company owned 220 convenience shopping centers consisting of 5.7 million square feet of gross leasable area (“GLA”).
Use of Estimates in Preparation of Financial Statements | 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 | 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 and six months ended June 30, 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 | 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 or the Common Units into which such LTIP Units have converted. All significant intercompany balances and transactions have been eliminated in consolidation.
Statements of Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information | Statements of Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information Non-cash investing and financing activities are summarized as follows (in millions):
| Six Months |

| 2026 |  |  | 2025 |
Accounts payable related to construction in progress | $ | 2.7 |  |  | $ | 3.2 |
Accounts receivable related to construction in progress |  | 12.3 |  |  |  | 2.1 |
Accounts payable related to future acquisitions |  | 0.8 |  |  |  | 1.0 |
Accounts payable related to finance costs |  | — |  |  |  | 0.3 |
Accounts payable related to offering expense |  | 0.5 |  |  |  | — |
Assumption of buildings due to ground lease terminations |  | 0.5 |  |  |  | 0.7 |
Dividends declared, but not paid |  | 19.6 |  |  |  | 17.4 |
Non-Controlling Interests | 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 | Segments The Company has a single 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 the chief executive officer. The CODM assesses performance for the segment and decides how to allocate resources based o n net income as reported in the consolidated statements of operations. In addition, the CODM uses net 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 | Equity In June 2026, the Company entered into an agreement (the “2026 Equity Sales Agreement”) for the future issuance of up to $400.0 million of common stock under an at-the-market equity offering program. In connection with the entry into the 2026 Equity Sales Agreement, the Company’s $250.0 million at-the-market equity offering program pursuant to the Company’s prior equity sales agreement, dated as of October 1, 2025 (the “2025 Equity Sales Agreement”) was terminated. As of its termination, shares of common stock having an aggregate offering price of approximately $7.1 million were not sold under the 2025 Equity Sales Agreement. Shares sold pursuant to the 2025 Equity Sales Agreement and the 2026 Equity Sales Agreement (together, the “ATM Program”) were offered and sold in amounts determined by the Company from time to time, and are sold in negotiated transactions at market prices prevailing at the time of sale. The ATM Program also allows the Company to enter into forward sale agreements which give the ability to lock in a share price on the sale of common stock at or shortly after the time the forward sale agreement becomes effective, while postponing the receipt of proceeds from the sale of shares until a future date. The Company evaluated the forward sale agreements in accordance with Accounting Standards Codification (“ASC”) Topic 815-40 and concluded that they meet the conditions to be classified within equity as of June 30, 2026. Shares issuable under a forward sale agreement are reflected in the diluted earnings per share calculations for the applicable periods using the treasury stock method. During the six months ended June 30, 2026, the Company offered and sold 8,640,212 shares of its common stock on a forward basis under the ATM Program at a weighted-average price of $27.10 per share, generating expected gross proceeds (assuming full physical settlement) of $234.2 million before issuance costs. The Company has settled 5,804,164 shares through June 30, 2026 that were sold under the ATM Program generating net proceeds of $134.8 million. As of June 30, 2026, the Company was party to forward sale agreements relating to 6,086,812 shares of common stock, with $173.1 million of expected gross proceeds (assuming full physical settlement) before issuance costs with final settlement dates ranging from March 31, 2027 through July 31, 2027 and had $333.2 million of remaining capacity under the ATM Program. In June 2026, the Company conducted a follow-on primary offering of 11,500,000 shares of its common stock on a forward basis, including the full exercise of the underwriters’ option to purchase up to 1,500,000 additional shares of common stock, at a public offering price of $30.85 per share for expected gross proceeds of $354.8 million before deducting underwriting discounts and expenses. The offering was completed in July 2026. The Company is required to settle these shares by December 2027. 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. The Company has settled 2,600,000 shares through June 30, 2026 generating net proceeds of $65.0 million. The Company is required to settle the remaining shares by August 2027.
Recently Issued Accounting Standards | 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. Other than additional disclosure, the adoption of this ASU is not expected to have a material impact on the Company’s financial position and/or results of operations.
