Public Storage Completes $10.5B NSAT Acquisition

Major Portfolio Consolidation in Self-Storage

Public Storage’s $10.5B acquisition of National Storage Affiliates Trust (NSAT) marks one of the largest self-storage mergers on record, according to Inside Self Storage. This merger hits as consolidation continues to reshape the self-storage REIT landscape, with operators seeking enhanced scale, market reach, and operational efficiency.

NSAT’s portfolio of more than 1,000 properties across 37 states and Puerto Rico significantly increases Public Storage’s national footprint. The combined entity now controls over 4,500 self-storage facilities, totaling 327M rentable SF, positioning Public Storage well ahead of its competitors in both number of locations and total rentable space.

The Details

Public Storage and NSAT closed the transaction on July 22. NSAT shareholders received 0.14 Public Storage shares for each NSAT share. Meanwhile, NSAT operating partnership unit holders received equivalent Public Storage OP units.

The acquisition should generate $110–130M in annual synergies within four years. These efficiencies should improve Public Storage’s earnings by $0.35–$0.50 per share. The transaction also included retiring NSAT’s debt and paying preferred shares.

Goldman Sachs and Wells Fargo secured a $4B financing package for the deal. Morgan Stanley and Clifford Chance advised NSAT. Goldman Sachs, Wells Fargo, and Eastdil Secured advised Public Storage.

Sun Belt Gains and REIT Sector Comparisons

The deal accelerates Public Storage’s expansion into high-growth regions, especially the Sun Belt. It reflects a broader shift toward growing southern and western metros. According to Green Street, Sun Belt self-storage occupancy consistently exceeded national averages over the previous four years.

The transaction will also create scale-based efficiencies for Public Storage. Sector leaders increasingly use larger, multi-state footprints to optimize operations. Extra Space Storage and CubeSmart have followed this strategy while expanding their portfolios.

Including this transaction, Public Storage’s equity market cap reaches $57B, well above its peers. That increased scale further strengthens its position among major self-storage REITs.

Why It Matters

This acquisition stands out because of both its size and timing. Self-storage has remained one of CRE’s most resilient sectors. Pandemic disruptions, migration patterns, and changing consumer behavior have supported demand in recent years.

By absorbing NSAT, Public Storage removes a major competitor and strengthens its pricing capabilities. The company can also streamline expenses and leverage its technology platforms. These factors support management’s “PS4.0 Value Creation Engine.”

Public Storage now operates 327M rentable SF, according to company disclosures. Before this transaction, it operated 258M SF. Its European partner, Shurgard, operates another 18M SF.

Shareholders on both sides also gained immediate and long-term benefits. NSAT holders received a premium through the all-stock transaction. Both REITs highlighted stronger operational synergies, broader digital reach, and greater financial flexibility.

Incoming CEO Tom Boyle positioned the deal as a major strategic milestone. He expects it to drive “per-share earnings and cash-flow growth.” Boyle also sees additional consolidation opportunities across the fragmented sector.

The top five US operators control less than 25% of national self-storage properties. That figure comes from the 2026 SSA Industry Report.

What’s Next

Public Storage will now focus on integrating more than 1,000 new facilities onto its platform. Most properties sit across Sun Belt and top-100 metro areas. Management targets $130M in annual synergies within four years.

The expansion comes as self-storage rates stabilize and new supply growth slows across the sector in 2026. These conditions could support portfolio performance as Public Storage integrates its newly acquired properties.

The company will likely pursue additional technology investments and organic growth. Expanded ancillary services, including tenant insurance, could support that strategy. Public Storage also holds the highest credit rating among publicly traded US REITs.

That financial position could support additional acquisitions and development opportunities. Management may target markets with lower barriers and stronger population inflows. The self-storage M&A cycle could remain active while fundamentals stay strong and capital remains accessible.
