The combined entity will create one of the largest self-storage operators in the United States, with substantial market presence across key metropolitan areas.

Public Storage, already the dominant player in the self-storage REIT sector, will further strengthen its market position through this acquisition. The deal comes amid continued consolidation in the real estate investment trust industry.

Deal Structure and Strategic Rationale

The all-stock transaction values National Storage Affiliates at $5.63 billion, with the combined company expected to have a market capitalization of approximately $57 billion². Public Storage will issue new shares to NSA shareholders as part of the merger consideration.

The acquisition expands Public Storage’s geographic footprint and operational scale in the self-storage market. National Storage Affiliates operates over 1,000 self-storage properties across 37 states and Puerto Rico, with approximately 70 million rentable square feet as of late 2025.

Industry Consolidation Continues

The merger represents the latest consolidation move in the self-storage REIT sector, where larger operators seek to achieve economies of scale and operational efficiencies. Public Storage’s acquisition of NSA follows a pattern of industry consolidation as companies look to optimize their portfolios and reduce operational costs.

Self-storage REITs have faced headwinds from higher interest rates and supply chain pressures, making consolidation an attractive strategy for achieving cost synergies and improving market positioning³.

Management Commentary

According to the merger announcement, both companies’ leadership teams emphasized the strategic value of combining their operations and portfolios. The transaction is expected to generate significant operational synergies through improved efficiency and reduced overhead costs.

A joint conference call was scheduled to discuss the transaction details and expected benefits for shareholders of both companies⁴.

Regulatory and Closing Timeline

The merger remains subject to customary closing conditions, including regulatory approval and shareholder votes from both companies. The transaction is expected to close in the coming months, pending satisfaction of all closing conditions.

Given the scale of the combined entity, the deal may face scrutiny from antitrust regulators examining market concentration in the self-storage industry.
