ITEM 8.01 OTHER EVENTS

The following sets forth certain recent developments for Extra Space Storage Inc.

Recent Developments

On November 1, 2012, we entered into a letter of intent to acquire a joint venture partner’s interest in one of our existing joint ventures that owns 21 self-storage properties in 11 states. All of the properties owned by the joint venture are currently operated by us under the Extra Space Storage brand. The joint venture properties contain approximately 1.7 million square feet of net rentable space in approximately 13,600 units. As of September 30, 2012, approximately 89.0% of the net rentable space at these properties was occupied. Upon closing, we expect to own 100% of the joint venture properties.

In addition, we have entered into definitive purchase agreements to acquire seven additional properties located in Florida, Maryland, Massachusetts and New Jersey, with an aggregate of approximately 575,000 square feet of net rentable space in approximately 5,800 units. As of September 30, 2012, approximately 86.6% of the net rentable space at these properties was occupied.

In total, we have agreed to acquire the above described properties for an aggregate purchase price of approximately $190.2 million, of which approximately $187.5 million is to be paid in cash at the respective closings and approximately $2.7 million of debt is to be assumed.

These acquisitions are subject to the completion of due diligence, the satisfaction of other closing conditions and, in the case of the acquisition of the joint venture partner’s interest, the negotiation and execution of a definitive purchase agreement. We intend to close each of these acquisitions by December 31, 2012; however, there can be no assurances that these conditions will be satisfied or that the acquisitions will close on the terms described herein, or at all.
