• Additional information:

1) This notification serves as a correction of the previous transparency notification dated 17 November 2023 in relation to the passive crossing of a threshold. It has been updated to include details regarding an internal reorganization within the Public Storage group (as further described below), which occurred before the aforementioned threshold was crossed.

As a result of the completion of a capital increase in cash via an accelerated bookbuilding procedure by Shurgard on 14 November 2023, the following thresholds were crossed passively:

• First threshold that was crossed (downwards): 70% (Total)
• Second threshold that was crossed (downwards): 35% (Shurgard European Holdings LLC).

2) Prior to the capital increase, on 14 August 2023, the Public Storage group (described in this notification) completed an internal reorganization for U.S. federal income tax purposes into a holding company structure where the parent company now holds its assets and conducts its operations through a controlled subsidiary limited partnership. The internal reorganization did not result in any change to the shareholders, officers, trustees, assets or liabilities of the Public Storage group or to the legal and regulatory obligations of the

Public Storage group under U.S. law. The internal reorganization did not change the Public Storage group subsidiaries that directly hold Shurgard Self Storage shares and did not result in any change to Public Storage group's ownership of such subsidiaries. There was no increase or decrease in the number of shares of Shurgard Self Storage directly held by the HABF European Investor entities described above.

3) In the context of the internal reorganisation, Public Storage (Real Estate Investment Trust), Public Storage OP, LP have been added to the chain of control. Public Storage has been renamed Public Storage Operating Company.
