National Storage Affiliates Shareholders: Ownership Structure, Brands, and Acquisition History
Last updated: Sep-2026Ownership Structure
Ownership Analysis
National Storage Affiliates changed ownership completely in July 2026. Public Storage acquired the former listed REIT, NSA shares stopped trading and Public Storage became the sole corporate parent. Former NSA institutional holdings are historical and should not appear as current direct ownership of the subsidiary.The acquisition used Public Storage shares as consideration. Each NSA common share converted into 0.14 Public Storage share, allowing former investors to retain exposure to self-storage through the buyer. Their rights now attach to Public Storage, not to an independent NSA board or security.The joint venture prevents a simple statement that Public Storage owns 100% of every former NSA property's economics. Legacy operating partnership limited partners hold about 80% of the venture containing 313 properties, while Public Storage holds about 20%. Public Storage nevertheless has exclusive management authority, so operational control and economic ownership are split.We describe the corporate owner as Public Storage at 100% and explain the property venture separately. This avoids confusing ownership of the acquired company with ownership percentages inside a downstream asset partnership. For customers and employees, Public Storage controls systems, branding and operating policies. For investors, the relevant listed security is PSA, and the venture contributes management economics plus a minority property interest.
Direct Owners
Institutional Shareholders
Shareholder Analysis
National Storage Affiliates no longer has a standalone shareholder register. Before closing, institutions and other investors held NSA common shares and elected its directors. Those shares were converted into Public Storage equity when the merger completed on July 22, 2026.Former NSA shareholders therefore participate only indirectly through Public Storage. Their economic outcome now includes the buyer's much larger portfolio, financing structure, development activity and capital-return policy. They cannot vote specifically on the former NSA brands, individual properties or management decisions.Legacy operating partnership limited partners are different from former common shareholders. Their interests were carried into a joint venture containing 313 properties, and they own about 80% of that venture. Those partnership units represent a direct economic interest in the venture, not ownership of the National Storage Affiliates corporate subsidiary.We omit old institutional percentages from the compact current field because they would imply that NSA still trades independently. Historical ownership remains relevant when explaining transaction approval and the origin of the joint venture. Current governance is simpler: Public Storage shareholders govern the public parent, Public Storage owns NSA, and legacy partners retain defined economics in a managed downstream venture.
Brands, Subsidiaries & Companies Owned
| Name | Type | Description |
|---|---|---|
| National Storage Affiliates | Company | Former public self-storage platform acquired by Public Storage |
| iStorage | Brand | Regional self-storage operating name transitioning to Public Storage |
| Move It Storage | Brand | Self-storage operating name in southern and western markets |
| Northwest Self Storage | Brand | Regional self-storage name in the Pacific Northwest |
| RightSpace Storage | Brand | Self-storage operating name across multiple states |
| SecurCare Self Storage | Brand | Regional self-storage name with a broad property network |
| Southern Self Storage | Brand | Self-storage operating name in southern markets |
Portfolio Analysis
National Storage Affiliates was built as a federation of regional self-storage brands. iStorage, SecurCare, Move It, Northwest Self Storage, RightSpace and Southern Self Storage each carried local market recognition. The structure let regional operators contribute properties and expertise while gaining public capital and shared systems.Those names describe customer-facing operations, not independent corporate owners after the acquisition. Public Storage controls the platform and has begun transitioning the portfolio to its orange brand. Central branding can simplify online search, reservations, account management and national marketing across more than 1,000 acquired properties.The rebrand should still be managed property by property. Lease systems, signs, gate access, call centers and digital listings must change without confusing existing tenants. Some facilities in the joint venture will use Public Storage's operating platform even though legacy partners retain most of the venture's economic interest.We list the legacy names because they identify the businesses customers may still encounter during transition. Their long-term value lies mainly in property locations, occupancy and local search history rather than permanent separation. Public Storage can retain selected names if they protect demand, but the announced direction is one operating and consumer identity backed by common technology, revenue management and customer service.
Market Share & Competitors
| Company | Market Share | Revenue | Key Strength |
|---|---|---|---|
| National Storage Affiliates ★ | N/A | $753M FY2025 | Former public self-storage platform now owned by Public Storage |
| Public Storage | N/A | $4.8B FY2025 | Largest United States self-storage owner and current parent |
| Extra Space Storage | N/A | $3.3B FY2025 | Large self-storage owner operator and third-party manager |
| CubeSmart | N/A | $1.1B FY2025 | Public self-storage REIT and management platform |
| U-Haul | N/A | $5.8B FY2025 | Moving and self-storage network |
Competitive Analysis
National Storage Affiliates competed with Public Storage, Extra Space Storage, CubeSmart and thousands of local operators. The sector rewards property density, convenient locations, online customer acquisition and disciplined rent management. Facilities are physically local, but digital search and national call centers make scale increasingly important.Under Public Storage, the former NSA portfolio gains a larger marketing platform, recognized brand and established operating technology. Public Storage can direct leads across nearby properties, apply revenue-management tools and spread corporate costs over a much wider network. Those advantages were central to the strategic logic of the acquisition.Extra Space remains a strong competitor because it combines owned facilities with a large third-party management business. CubeSmart has a similar management capability, while U-Haul pairs storage with moving services. Local owners can compete through price, service and sites that large REITs cannot replicate.The main risk is not brand awareness but local supply and consumer behavior. Self-storage demand responds to moves, household changes, housing turnover and business use. Aggressive rent increases can raise revenue while increasing churn. Public Storage must integrate the NSA properties without disrupting customers and must avoid paying for scale that does not produce durable per-property cash flow.
Acquisitions
| Company Acquired | Deal Value | Year | Description |
|---|---|---|---|
| Public Storage acquisition | $10.5B | 2026 | Transferred the former public company and its property platform to Public Storage |
| Move It Storage portfolio | $1.4B | 2022 | Expanded the property base and operating scale |
| Northwest Self Storage portfolio | $1.3B | 2021 | Added a major Pacific Northwest storage platform |
Acquisitions Analysis
National Storage Affiliates used large portfolio purchases to expand before it became an acquisition target. The 2021 Northwest Self Storage transaction, valued at $1.3 billion, added scale in the Pacific Northwest and strengthened a regional market where local density improves marketing and operations.The 2022 Move It Storage portfolio purchase, valued at $1.4 billion, extended the network across southern and western markets. These deals accelerated property growth but also increased financing needs. Like other self-storage acquisitions, their returns depended on occupancy, rent increases, property taxes and the buyer's ability to integrate digital marketing and pricing.Public Storage's $10.5 billion acquisition in 2026 sits above the earlier portfolio deals. It transferred the entire public platform, including operating systems, brands and personnel, to a larger competitor. The consideration was Public Storage stock, and the stated total included assumed debt.We view the acquisition as a scale and consolidation transaction. Public Storage gains properties, customers and market density, while former NSA investors gain shares in a larger platform. The joint venture structure preserved legacy partner interests without leaving NSA public. Success should be assessed through integration costs, property retention, occupancy, revenue growth and the incremental cash generated after financing and joint venture distributions.
Acquisition Timeline
Merger & Spin-off History
Merger & Spin-off Analysis
National Storage Affiliates was formed in 2013 to combine regional operators within one public REIT framework. The company completed an initial public offering in 2015. Participating regional operators contributed properties and retained roles in local operations, producing a distinctive federated structure.In July 2024, NSA internalized the participating regional operator model. That step simplified governance and brought more operating responsibility into the public company before the strategic sale. It did not change ultimate public ownership at the time, but it reduced reliance on semi-autonomous regional structures.Public Storage announced the acquisition in 2025 and completed it on July 22, 2026. The share exchange ended NSA's independent listing. A joint venture created at closing preserved economic interests for legacy operating partnership limited partners in 313 properties while giving Public Storage exclusive management authority.There has been no spinoff restoring NSA as a separate issuer. The merger history moves in the opposite direction: regional operators became one REIT, the REIT internalized operations, and the resulting platform joined Public Storage. The remaining NSA name is best viewed as a legacy corporate and portfolio reference during integration, not a continuing independent ownership structure.
Ownership History
Ownership History Analysis
National Storage Affiliates began in 2013 with a model that invited established regional self-storage operators to join a shared public platform. The approach preserved local expertise and brand identities while providing access to centralized financing, acquisitions and reporting.The 2015 initial public offering transferred ownership to public shareholders and funded portfolio growth. Large purchases such as Northwest Self Storage and Move It expanded the company, while the regional brands remained visible to customers across different states.NSA internalized its participating regional operator structure in 2024. That change prepared a more unified operating organization, but the company soon entered a sale process. Public Storage's offer gave common shareholders stock in a larger self-storage REIT and provided a mechanism for legacy partners to retain interests through a new venture.The transaction closed in July 2026. Public Storage now owns the former company, manages the retained and venture properties, and is transitioning the brands. The ownership history is therefore complete as a standalone public story. Future results of the former NSA assets will appear within Public Storage and the managed joint venture rather than through an NSA ticker or independent annual meeting.
Ownership Explained
National Storage Affiliates is no longer an independent public company. Public Storage completed the $10.5 billion acquisition on July 22, 2026, and former NSA shareholders received Public Storage shares. NSA's former ticker was removed, and Public Storage now controls the acquired corporate platform.The property structure includes an important joint venture. At closing, 313 former NSA properties were placed into a venture owned mainly by legacy operating partnership limited partners, with Public Storage holding about 20%. Public Storage exclusively manages those properties even though it does not own the full venture economics.
Public Storage's acquisition ended direct ownership by NSA common shareholders. Former investors received 0.14 Public Storage share for each NSA share, shifting their exposure from a smaller specialist REIT to the largest public self-storage platform. They no longer elect an NSA board or vote on a standalone strategy. Governance, financing and capital allocation now flow through Public Storage.The transaction did not place every former NSA property in the same economic bucket. Public Storage owns the acquired company and the properties retained directly, while 313 properties sit in a managed joint venture. Legacy NSA operating partnership limited partners hold about 80% of that venture and Public Storage holds about 20%. Public Storage still controls property management and branding through an exclusive arrangement.Customers should expect a gradual transition from regional names such as iStorage, SecurCare, Move It and Northwest Self Storage to the Public Storage brand and operating system. A unified identity can improve digital marketing, pricing tools and customer recognition. It can also remove local brand equity that helped the regional operator model build relationships in specific markets.The $10.5 billion purchase increases Public Storage's scale by more than 1,000 properties and more than 550,000 units. Value creation depends on occupancy, rental rates, cost savings and successful technology migration. We would not use NSA's old shareholder percentages as current ownership. The accurate current picture is full corporate control by Public Storage, combined with minority economic interests held by legacy partners in the separate managed property venture.
