2026 Director Nominees

Our Board of Directors (the “Board”) strives to maintain an independent, balanced and diverse set of Directors that collectively possess the skills and expertise to provide effective oversight of management and the execution of the Company’s strategy. Two of our Director nominees are women and one of our Director nominees is a member of an underrepresented community, which the Company defines as someone who self-identifies as Black, African American, North African, Middle Eastern, Hispanic, Latino, Asian, Pacific Islander, Native American, Native Hawaiian, Alaskan Native, or a member of the LGBTQIA+ community. The average age of our Director nominees is 57 years and the average tenure of our Director nominees is five years.

2025 Performance Highlights

In 2025, the Company sold 14 wholly-owned properties for an aggregate gross sales price of approximately $752.5 million, repaid approximately $306.8 million of consolidated mortgage debt and returned approximately $355.7 million to shareholders ($6.75 per share) through special dividends. In recognition of the volume of the Company’s asset sales and the reduced scale of its operations, in December 2025, the Company announced its intention to market its remaining properties for sale and monetize the value of its remaining joint venture investments.

As of March 30, 2026, the Company had sold two additional wholly-owned properties and its interest in one joint venture property during 2026 for approximately $95.3 million in the aggregate, leaving the Company with six wholly-owned shopping centers, a 20% interest in a joint venture that owned ten shopping centers, and our corporate headquarters in Beachwood, Ohio.

Corporate Governance Highlights

We remain committed to high standards of corporate governance, which we believe promote management of the Company for the benefit of our stakeholders as it pursues its disposition strategy.

Compensation Practices

On October 1, 2024, the Company completed thespin-off of Curbline Properties Corp. (“Curbline Properties”), the first publicly traded REIT focused on the convenience property sector. In connection with thespin-off, the employment of Mr. Lukes, the Company’s CEO, and Mr. Cattonar, the Company’s Chief Investment Officer (“CIO”), was transferred to Curbline Properties and the Company entered into a shared services agreement with Curbline Properties and its affiliates (the “Shared Services Agreement”). Pursuant to the terms of the Shared Services Agreement, Curbline Properties and its affiliates are responsible for (1) providing the Company with leadership and management services, including a CEO and a CIO, and (2) making all compensation determinations for and payments to any CEO and CIO provided to the Company by Curbline Properties. Under this arrangement, since thespin-off of Curbline Properties, Messrs. Lukes and Cattonar have continued to serve as our CEO and CIO, respectively; however, they are not employed by the Company, and the Company is not obligated to provide any direct or indirect compensation for their service as our CEO or CIO. Further, to the Company’s knowledge, Curbline Properties did not provide Messrs. Lukes and Cattonar with any compensation specifically for their service to us as our CEO and CIO, respectively, during 2025.

The Company continues to be responsible for the compensation of our named executive officers who are employed by the Company (namely Gerald R. Morgan, our Chief Financial Officer (“CFO”), and Aaron M. Kitlowski, our General Counsel), and the Compensation Committee continues to oversee the design and administration of, and changes to, the Company’s compensation programs with respect to these executives.

2025 Executive Compensation

The table below summarizes 2025 compensation awarded or paid by the Company to our named executive officers as reported in the 2025 Summary Compensation Table included in this Proxy Statement. Historically, our Compensation Committee has established both quantitative and qualitative performance metrics governing our annual incentive compensation program in the first quarter of each year. However, in recognition of the Company’s plan to market a significant number of properties for sale during 2025 and the inability to forecast the timing and impact of these sales on the Company’s financial results and operating metrics, the Compensation Committee determined in early 2025 that payouts to the Company’s employed executives under the 2025 annual incentive compensation program would be based entirely on the Compensation Committee’syear-end qualitative assessment of their performance (subject to the terms set forth in each executive’s employment agreement).

In February 2026, based on a qualitative assessment of their performance during 2025, the Compensation Committee approved incentive compensation payouts for Messrs. Morgan and Kitlowski of $300,000 and $675,000, respectively, which represented the maximum amount of the annual incentive award opportunities provided for under their employment agreements.
