Litigation Matters

On July 1, 2024, a purported shareholder of the Company filed a class action lawsuit in the U.S. District Court for the Southern District of New York, captioned Zhengxu He, Trustee of the He & Fang 2005 Revocable Living Trust v. Seritage Growth Properties, Case No. 1:24:CV:05007, alleging that the Company, the Company’s Chief Executive Officer, and the Company’s Chief Financial Officer violated the federal securities laws (the “Securities Action”). The complaint seeks to bring a class action on behalf of all persons and entities that purchased or otherwise acquired Company securities between July 7, 2022 and May 10, 2024. The complaint alleges that the defendants violated federal securities laws by issuing false, misleading, and/or omissive disclosures concerning the Company’s alleged lack of effective internal controls regarding the identification and review of impairment indicators for investments in real estate and the Company’s value and projected gross proceeds of certain real estate assets. The complaint seeks compensatory damages in an unspecified amount to be proven at trial, an award of reasonable costs and expenses to the plaintiff and class counsel, and such other and further relief as the court may deem just and proper. On or around January 15, 2025, another purported shareholder of the Company filed a derivative lawsuit in the U.S. District Court for the District of Maryland, captioned Paul Sidhu v. Seritage Growth Properties, Case No. 1:25-cv-00152 (the “Sidhu Derivative Action”). On or around January 20, 2025, another purported shareholder of the Company filed a derivative lawsuit in the U.S. District Court for the District of Maryland, captioned James Wallen v. Seritage Growth Properties, Case No. 1:25-cv-00190 (the “Wallen Derivative Action”). On or around May 8, 2025, another purported shareholder of the Company filed a derivative lawsuit in the U.S. District Court for the Southern District of New York, captioned Derrick Cheroti v. Seritage Growth

Properties, Case No. 1:25-vc-00152 (the “Cheroti Derivative Action”). The derivative actions allege the same or similar claimed acts and omissions underlying the Securities Action, assert breach of fiduciary duty and other claims against the Company’s Chief Executive Officer, the Company’s Chief Financial Officer, and current and former members of the Company’s Board of Trustees, and name the Company as a nominal defendant. The complaint in each of the derivative actions seeks compensatory damages in an unspecified amount to be proven at trial, an order directing the Company and the individual defendants to reform and improve the Company’s corporate governance and internal procedures, restitution from the individual defendants, an award of costs and expenses to the plaintiff and reasonable attorneys’ and experts’ fees, costs, and expenses, and such other and further relief as the court may deem just and proper. The complaint in the Cheroti Derivative Action also seeks an award of punitive damages, an order directing the individual defendants to account for all damages caused by them and all profits and special benefits and unjust enrichment obtained, and the imposition of a constructive trust. On September 2, 2025, the court in the Cheroti Derivative Action stayed the Cheroti Derivative Action until resolution of the anticipated motion to dismiss in the Securities Action. On November 5, 2025, the court in the District of Maryland proceedings consolidated the Sidhu Derivative Action and the Wallen Derivative Action (the “Consolidated Derivative Action”) and appointed lead counsel. On November 12, 2025, the court in the Consolidated Derivative Action stayed the Consolidated Derivative Action until resolution of the anticipated motion to dismiss in the Securities Action. The Company intends to vigorously defend itself against the allegations in these lawsuits.

Strategic Review

At the 2022 Annual Meeting of Shareholders on October 24, 2022, Seritage shareholders approved the Company’s Plan of Sale. The strategic review process remains ongoing as the Company executes the Plan of Sale, and the Company remains open-minded to pursuing value-maximizing alternatives, including a potential sale of the Company. There can be no assurance regarding the success of the process.

Market Update

The Company continues to face challenging market conditions, such as elevated interest rates and the availability of debt and equity capital, and it continues to assess other potential macroeconomic impacts including supply chain issues, international conflicts associated with tariffs, potential labor issues, and uncertainty caused by wars and the impacts thereof. While interest rates have started to decline, they remain high relative to interest rates in 2022. Additionally, raising equity capital for land development deals remains challenging. These conditions could apply downward pricing pressures on our remaining assets. In making decisions regarding whether and when to transact on each of the Company’s remaining assets, the Company considers various factors including, but not limited to, the breadth of the buyer universe, macroeconomic conditions including the availability and cost of financing, as well as corporate, operating and other capital expenses required to carry the asset. If these challenging market conditions persist, then we expect that they will continue to adversely impact the Plan of Sale proceeds from our assets and the amounts and timing of distributions to shareholders.
