New York, New York, July 28, 2026 – Curbline Properties Corp. (NYSE: CURB) (the “Company” or “Curbline”), an owner of convenience centers in suburban, high household income communities, announced today operating results for the quarter ended June 30, 2026. For the six months ended June 30, 2026, net income attributable to Curbline was $10.5 million, or $0.10 per diluted share, as compared to net income of $20.9 million, or $0.20 per diluted share, in the year-ago period.

“Curbline’s second quarter results highlight the strength of the platform that we have constructed with record investment volume of $375 million, over $500 million of capital raised, and an uptick in leasing volume with the vast majority of the Company’s SNO pipeline expected to commence rent payment by March 2027. Curbline is again raising its full year investment target and OFFO guidance range given the significant outperformance to date with all cash and capital commitments needed to fund the revised investment pipeline on hand,” commented David R. Lukes, President and Chief Executive Officer. “Looking forward, we believe Curbline remains uniquely positioned for growth given its differentiated investment focus, the leasing economics of the Company’s property type, and its balance sheet.”

Results for the Second Quarter

• Second quarter net income attributable to Curbline was $6.9 million, or $0.06 per diluted share, as compared to net income of $10.4 million, or $0.10 per diluted share, in the year-ago period. The decrease year-over-year was primarily due to an increase in interest expense and in depreciation and amortization expense, partially offset by the net impact of asset acquisitions.
• Second quarter operating funds from operations attributable to Curbline (“Operating FFO” or “OFFO”) was $33.3 million, or $0.31 per diluted share, compared to $26.9 million, or $0.26 per diluted share, in the year-ago period. The increase year-over-year was primarily due to the net impact of asset acquisitions, partially offset by an increase in interest expense and a higher weighted-average share count resulting from shares issued to fund acquisitions.

Significant Second Quarter Activity and Recent Activity

• During the second quarter, acquired 30 convenience shopping centers for an aggregate purchase price of $374.1 million.
• During the second quarter, sold 6.6 million shares of common stock on a forward basis under its at-the-market equity offering program for expected gross proceeds of $186.5 million before issuance costs.
• In June, conducted an offering of 11.5 million shares of common stock on a forward basis generating expected gross proceeds of $354.8 million before issuance costs.
• During the second quarter, settled 8.4 million shares of common stock that were sold on a forward basis generating net proceeds of $199.8 million.
• In June, issued the Company's 2025 Corporate Sustainability Report marking both the first report as a standalone public company and Curbline’s first full year of sustainability reporting. The report was completed in alignment with the Task Force on Climate Related Financial Disclosure and can be found at (https://curbline.com/our-story#sustainability).
• As of June 30, 2026, adjusted for forward equity sales completed year to date, the Company had $850.9 million of cash and capital commitments for future acquisitions, including $154.7 million of cash and $696.2 million of expected gross proceeds from unsettled forward equity sales.
• In the third quarter to date, acquired four convenience shopping centers for an aggregate purchase price of $47.1 million.

Significant Year to Date 2026 Activity

• Year to date, acquired 48 convenience shopping centers for an aggregate purchase price of $563.7 million.
• Year to date, sold 29.3 million shares of common stock on a forward basis in follow-on public offerings and under its at-the-market equity offering program, generating expected gross proceeds of $823.5 million before issuance costs.

Key Quarterly Operating Results

• Reported an increase of 2.1% in same-property net operating income (“SPNOI”) for the six-month period ended June 30, 2026 compared to June 30, 2025.
• Generated cash new leasing spreads of 20.2% and cash renewal leasing spreads of 7.4%, for the trailing twelve-month period ended June 30, 2026 and cash new leasing spreads of 8.2% and cash renewal leasing spreads of 8.6% for the second quarter of 2026.
• Generated straight-lined new leasing spreads of 35.7% and straight-lined renewal leasing spreads of 17.1%, for the trailing twelve-month period ended June 30, 2026 and straight-lined new leasing spreads of 27.1% and straight-lined renewal leasing spreads of 18.1% for the second quarter of 2026.
• Reported a leased rate of 96.5% at June 30, 2026 compared to 96.1% at June 30, 2025 and 96.7% at December 31, 2025. The sequential increase was due to an acceleration in net leasing activity, partially offset by an approximately 20 basis point impact from acquisitions.
• As of June 30, 2026, the Signed Not Opened spread was 220 basis points, representing $7.6 million of annualized base rent.

Non-GAAP Measures and Other Operational Metrics

Funds from Operations (“FFO”) is a supplemental non-GAAP financial measure used as a standard in the real estate industry and is a widely accepted measure of REIT performance. The Company believes that both FFO and Operating FFO provide additional indicators of the financial performance of a REIT, more appropriately measure the core operations of the Company, and provide benchmarks to its peer group.

FFO is generally defined and calculated by the Company as net income attributable to Curbline (computed in accordance with Generally Accepted Accounting Principles in the United States (“GAAP”)), adjusted to exclude (i) gains and losses from disposition of real estate property, which are presented net of taxes, (ii) impairment charges on real estate property, (iii) gains and losses from changes in control and (iv) certain non-cash items. These non-cash items principally include real property depreciation and amortization of intangibles net of depreciation allocated to non-controlling interests. The Company’s calculation of FFO is consistent with the definition of FFO provided by NAREIT. The Company calculates Operating FFO as FFO excluding certain non-operating charges, income and gains/losses. Operating FFO is useful to investors as the Company removes non-comparable charges, income and gains/losses to analyze the results of its operations and assess performance of the core operating real estate portfolio. Other real estate companies may calculate FFO and Operating FFO in a different manner.

In calculating the expected range for or amount of net income attributable to Curbline to estimate projected FFO and Operating FFO for future periods, the Company does not include a projection of gains and losses from the disposition of real estate property, potential impairments and reserves of real estate property, debt extinguishment costs and certain transaction costs. Other real estate companies may calculate expected FFO and Operating FFO in a different manner.

The Company also uses net operating income (“NOI”), a non-GAAP financial measure, as a supplemental performance measure. NOI is calculated as property revenues less property-related expenses and excludes depreciation and amortization expense, interest income and expense and corporate level transactions. The Company believes NOI provides useful information to investors regarding the Company’s financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level and, when compared across periods, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and disposition activity on an unleveraged basis.

The Company presents NOI information herein on a same-property basis (“SPNOI”). The Company defines SPNOI as property revenues less property-related expenses, which excludes depreciation and amortization expense, interest income and expense and corporate level transactions, as well as straight-line rental income and reimbursements and expenses, lease termination income, management fee expense and fair market value of leases. SPNOI only includes assets owned for the entirety of both comparable periods. Other real estate companies may calculate NOI and SPNOI in a different manner. The Company believes SPNOI provides investors with additional information regarding the operating performance of comparable assets because it excludes certain non-cash and non-comparable items as noted above.

FFO, Operating FFO, NOI and SPNOI do not represent cash generated from operating activities in accordance with GAAP, are not necessarily indicative of cash available to fund cash needs and should not be considered as alternatives to net income computed in accordance with GAAP, as indicators of the Company’s operating performance or as alternatives to cash flow as a measure of liquidity. Reconciliations of these non-GAAP measures to their most directly comparable GAAP measures have been provided herein.

The Company calculates Cash Leasing Spreads by comparing the prior tenant's annual base rent in the final year of the prior lease to the executed tenant’s annual base rent in the first year of the executed lease. Straight-Lined Leasing Spreads are calculated by comparing the prior tenant’s average base rent over the prior lease term to the executed tenant’s average base rent over the term of the executed lease. For both Cash and Straight-Lined Leasing Spreads, the reported calculation excludes first generation units and spaces vacant at the time of acquisition and includes all leases for spaces vacant greater than twelve months along with split and combination deals.

Performance Measures

FFO and Operating FFO

The Company believes that Funds from Operations (“FFO”) and Operating FFO, both non-GAAP financial measures, provide additional and useful means to assess the financial performance of REITs. FFO and Operating FFO are frequently used by the real estate industry, as well as securities analysts, investors and other interested parties, to evaluate the performance of REITs. The Company also believes that FFO and Operating FFO more appropriately measure the core operations of the Company and provide benchmarks to its peer group.

FFO excludes GAAP historical cost depreciation and amortization of real estate and real estate investments, which assume that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions, and many companies use different depreciable lives and methods. Because FFO excludes depreciation and amortization unique to real estate and gains and losses from property dispositions, it can provide a performance measure that, when compared year over year, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, interest costs and acquisition, disposition and development activities. This provides a perspective of the Company’s financial performance not immediately apparent from net income determined in accordance with GAAP.

FFO is generally defined and calculated by the Company as net income attributable to Curbline (computed in accordance with GAAP), adjusted to exclude (i) gains and losses from disposition of real estate property, which are presented net of taxes, (ii) impairment charges on real estate property, (iii) gains and losses from changes in control and (iv) certain non-cash items. These non-cash items principally include real property depreciation and amortization of intangibles net of depreciation allocated to non-controlling interests. The Company’s calculation of FFO is consistent with the definition of FFO provided by NAREIT.

The Company believes that certain charges, income and gains/losses recorded in its operating results are not comparable or reflective of its core operating performance. Operating FFO is useful to investors as the Company removes non-comparable charges, income and gains to analyze the results of its operations and assess performance of the core operating real estate portfolio. As a result, the Company also computes Operating FFO and discusses it with the users of its financial statements, in addition to other measures such as net income (loss) determined in accordance with GAAP and FFO. Operating FFO is generally defined and calculated by the Company as FFO excluding certain charges, income and gains/losses that management believes are not comparable and indicative of the results of the Company’s operating real estate portfolio. Such adjustments include gains/losses on the early extinguishments of debt, transaction costs and other restructuring type costs, including employee separation costs. The disclosure of these adjustments is regularly requested by users of the Company’s financial statements. The adjustment for these charges, income and gains/losses may not be comparable to how other REITs or real estate companies calculate their results of operations, and the Company’s calculation of Operating FFO differs from NAREIT’s definition of FFO. Additionally, the Company provides no assurances that these charges, income and gains/losses are non-recurring. These charges, income and gains/losses could be reasonably expected to recur in future results of operations.

These measures of performance are used by the Company for several business purposes and by other REITs. The Company uses FFO and/or Operating FFO in part (i) as a disclosure to improve the understanding of the Company’s operating results among the investing public, (ii) as a measure of a real estate asset’s performance, (iii) to influence acquisition, disposition and capital investment strategies and (iv) to compare the Company’s performance to that of other publicly traded shopping center REITs. For the reasons described above, management believes that FFO and Operating FFO provide the Company and investors with an important indicator of the Company’s operating performance. They provide recognized measures of performance other than GAAP net income, which may include non-cash items (often significant).

In calculating the expected range for or amount of net income attributable to Curbline to estimate projected FFO and Operating FFO for future periods, the Company does not include a projection of gains and losses from the disposition of real estate property, potential impairments and reserves of real estate property, debt extinguishment costs or transaction costs. Other real estate companies may calculate expected FFO and Operating FFO in a different manner.

Management recognizes the limitations of FFO and Operating FFO when compared to GAAP’s net income. FFO and Operating FFO do not represent amounts available for dividends, capital replacement or expansion, debt service obligations or other commitments and uncertainties. Management does not use FFO or Operating FFO as an indicator of the Company’s cash obligations and funding requirements for future commitments, acquisitions or development activities. Neither FFO nor Operating FFO represents cash generated from operating activities in accordance with GAAP, and neither is necessarily indicative of cash available to fund cash needs. Neither FFO nor Operating FFO should be considered an alternative to net income (computed in accordance with GAAP) or as an alternative to cash flow as a measure of liquidity. FFO and Operating FFO are simply used as additional indicators of the Company’s operating performance. The Company believes that to further understand its performance, FFO and Operating FFO should be compared with the Company’s reported net income (loss) and considered in addition to cash flows determined in accordance with GAAP, as presented in its condensed financial statements. Reconciliations of these measures to their most directly comparable GAAP measure of net income (loss) have been provided herein.

Net Operating Income (“NOI”) and Same-Property Net Operating Income (“SPNOI”) The Company uses NOI, which is a non-GAAP financial measure, as a supplemental performance measure. NOI is calculated as property revenues less property-related expenses and excludes depreciation and amortization expense, interest income and expense and corporate level transactions. The Company believes NOI provides useful information to investors regarding the Company’s financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level and, when compared across periods, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and disposition activity on an unleveraged basis.

The Company also presents NOI information on a same-property basis, or SPNOI. The Company defines SPNOI as property revenues less property-related expenses, which excludes depreciation and amortization expense, interest income and expense and corporate level transactions, as well as straight-line rental income and reimbursements and expenses, lease termination income, management fee expense and fair market value of leases. SPNOI only includes assets owned for the entirety of both comparable periods. Other real estate companies may calculate NOI and SPNOI in a different manner. The Company believes SPNOI provides investors with additional information regarding the operating performance of comparable assets because it excludes certain non-cash and non-comparable items as noted above. SPNOI is frequently used by the real estate industry, as well as securities analysts, investors and other interested parties, to evaluate the performance of REITs.

SPNOI is not, and is not intended to be, a presentation in accordance with GAAP. SPNOI information has its limitations as it excludes any capital expenditures associated with the re-leasing of tenant space or as needed to operate the assets. SPNOI does not represent amounts available for dividends, capital replacement or expansion, debt service obligations or other commitments and uncertainties. Management does not use SPNOI as an indicator of the Company’s cash obligations and funding requirements for future commitments, acquisitions or development activities. SPNOI does not represent cash generated from operating activities in accordance with GAAP and is not necessarily indicative of cash available to fund cash needs. SPNOI should not be considered as an alternative to net income (computed in accordance with GAAP) or as an alternative to cash flow as a measure of liquidity. A reconciliation of NOI and SPNOI to its most directly comparable GAAP measure of net income (loss) has been provided herein.
