On March 16, 2026, Public Storage announced an agreement to acquire National Storage Affiliates Trust in an all-stock transaction, in a deal valued at approximately $10.5Bn.
The transaction is anticipated to close in the third quarter of 2026, subject to customary regulatory approvals and shareholder consent.
The transaction represents one of the largest consolidations within the U.S. self-storage sector and reflects continued strategic positioning among real estate investment trusts (REITs) seeking greater scale, operational efficiencies and enhanced geographic diversification. The acquisition is expected to strengthen Public Storage’s presence across regional markets while further consolidating a fragmented industry.
Transaction Structure
The transaction is structured as an all-stock acquisition. This allows Public Storage to preserve liquidity while aligning shareholder interests between the two companies. Under the terms of the agreement, holders of NSA common shares and operating partnership units will receive about 0.14 of a share of PSA common stock or partnership units for each NSA share they own. However, the final capital structure at closing will depend on shareholder elections and financing terms.
Additionally, Public Storage has secured $4Bn in committed financing from Goldman Sachs and Wells Fargo to refinance National Storage Affiliates’ existing debt and support the post-transaction capital structure.
Strategic Rationale and Synergy Expectations
Public Storage is a Glendale, California-based real estate investment trust and one of the largest owners, operators and developers of self-storage facilities in the United States and globally. National Storage Affiliates Trust is a self-administered, self-managed REIT focused on the ownership, operation and acquisition of self-storage properties, with a portfolio spanning hundreds of facilities across suburban and secondary markets.
Public Storage is likely acquiring National Storage Affiliates to expand its position in high-growth suburban markets such as the Sun Belt. The transaction is expected to generate $110MM to $130MM in annual synergies following the integration period.
National Storage Affiliates’ portfolio includes a significant concentration of properties in regions characterized by population migration trends, lower development costs and favorable demographic expansion — factors that may support long-term occupancy stability and rental rate growth.
By integrating National Storage Affiliates’ assets into its broader platform, Public Storage may be able to streamline operations and expand margins over time. These factors may contribute to long-term value creation while reinforcing Public Storage’s position as a leading platform within the self-storage sector.
Public Storage’s A / A2 credit rating is the highest of any publicly traded U.S. REIT. The combined entity plans to utilize this cost of capital advantage and increased free cash flow to fund future growth initiatives. Following realization of cost synergies, the transaction is expected to be leverage-neutral.
Market Context
The transaction reflects sustained investor interest in the $60Bn-$70Bn U.S. self-storage sector over the past decade, supported by stable cash flows, low operating costs and consistent demand drivers such as residential mobility, downsizing and small business usage. Unlike other real estate asset classes, self-storage has historically demonstrated resilience during periods of economic volatility, as demand tends to be driven by life events rather than purely cyclical factors.
Industry consolidation has accelerated as larger REITs seek to acquire smaller or regionally concentrated operators to expand their portfolios and improve operating efficiency. The acquisition of National Storage Affiliates aligns with this broader trend, as scale has become an increasingly important competitive advantage in pricing, customer acquisition and operational optimization.
The sector’s ability to generate consistent cash flow with limited operational complexity may continue to attract both institutional and retail capital, reinforcing its position as a defensive asset class within real estate.
Broader macroeconomic conditions have also influenced consolidation trends within the sector. Elevated interest rates and tighter capital markets have increased financing costs for smaller operators, potentially limiting their ability to expand independently. As a result, REITs such as Public Storage may be better positioned to pursue strategic acquisitions. This dynamic may continue to drive M&A activity within the self-storage industry as larger platforms seek to deploy capital efficiently and strengthen competitive positioning.
Industry Implications
The transaction may signal continued consolidation within the self-storage industry, particularly among publicly traded REITs seeking to enhance portfolio scale and geographic reach. As larger platforms expand their capabilities in pricing optimization, digital marketing and customer retention, smaller operators may face increased competitive pressure and may become more likely acquisition targets. This dynamic may reflect broader industry trends in which scale and operational sophistication continue to drive competitive differentiation.
Closing Conditions
Both companies’ Boards of Trustees have unanimously approved the transaction, which is expected to close in the third quarter of 2026. However, the agreement is subject to customary closing conditions, including required shareholder approval and receipt of regulatory approvals. The transaction’s closing date will depend on the satisfaction of these conditions and the completion of requisite financing arrangements.
