Self-Storage Merger: Combining 1st and 5th Places for a $14 Billion Big Deal

Public Storage (PSA) has signed a definitive agreement to acquire National Storage Affiliates (NSA), the fifth-largest self-storage operator in the United States, in a stock-for-stock transaction valued at approximately $10.5 billion (including debt), or roughly KRW 14 trillion. Under the terms of the merger, NSA shareholders will receive 0.14 shares of PSA common stock for each NSA share held, resulting in a pro forma ownership split of about 92% PSA shareholders and 8% NSA shareholders.

As part of the transaction, PSA and NSA will form a joint venture—“High Cash Flow Assets”—to hold 313 of NSA’s most productive properties. Existing NSA operating-partnership equity holders will own 80% of the joint venture, and PSA will hold the remaining 20%. PSA will assume and refinance NSA’s existing debt and preferred equity and fund the remaining acquisition consideration with new secured and unsecured borrowings.

PSA expects the merger to have a neutral impact on funds from operations (FFO) per share in 2026, to add $0.10–$0.20 per share in 2027, and to deliver $0.35–$0.50 per share (2–3%) accretion once fully integrated in 2028–2029. These gains are projected to come from approximately $110–$130 million in annual synergies driven by revenue optimization, margin improvement, tenant reinsurance, and G&A efficiencies.

The combined company will operate under a single brand across 42 states and Puerto Rico, with 4,596 locations—making it the largest self-storage platform in the U.S. PSA plans to leverage its digital and operational frameworks, PS4.0 and PS Next, to enhance both efficiency and scale. The transaction remains subject to customary closing conditions, including approval by NSA’s equity holders, and is targeted to close in the third quarter of 2026.

In conjunction with the merger announcement, PSA and NSA released a joint proxy statement, press release, and investor presentation. PSA is also relocating its headquarters from Glendale, California, to Frisco, Texas, and will appoint Tom Boyle as CEO effective April 1, 2026, as part of its broader organizational transformation tied to the launch of the PS4.0 digital operating platform.

Public Storage is the world’s largest publicly traded self-storage REIT, alongside peers such as Extra Space Storage and CubeSmart. The U.S. self-storage market comprises a mix of national REITs and regional operators, and this transaction is viewed as a significant consolidation move that could reshape market share and drive greater economies of scale among the industry’s leading players.
