Public Storage Completes National Storage Affiliates Trust Acquisition, Issues Preferred Units

Merger Structure and Transaction Components

Public Storage executed the acquisition of National Storage Affiliates Trust through a comprehensive multi-step transaction that involved coordination between both companies' operating partnerships and subsidiary entities. The disclosure states that the transaction was structured to include a dropdown contribution from NSA's operating partnership, followed by a company-level merger in which National Storage Affiliates Trust merged into Merger Sub I, a wholly owned Maryland limited liability company subsidiary of Public Storage. This structure allowed for sequential completion of multiple transaction components designed to facilitate the integration of the two real estate investment trusts.

The transaction also involved redemption of Class A operating partnership units held in NSA's operating partnership structure immediately prior to a final partnership-level merger. Following these transactions, NSA's operating partnership merged into Public Storage's operating partnership, with Public Storage's operating partnership continuing as the surviving entity. This multi-layered approach enabled the parties to address both corporate and partnership-level considerations while maintaining continuity of the combined entity's operations.

Preferred Share Issuance and Unit Conversion

In connection with the merger completion, Public Storage issued new Series T and Series U Cumulative Redeemable Preferred Shares, each carrying a 6.000% dividend distribution rate. These preferred shares were issued to holders of NSA's prior preferred interests in its operating partnership. The disclosure indicates that corresponding Series T, Series U, and Series T-1 Cumulative Redeemable Preferred Units were simultaneously issued in Public Storage's operating partnership. The filing states that these units were issued upon conversion of NSA's operating partnership preferred units, specifically converting NSA's Series A and Series B Cumulative Redeemable Preferred Units, as well as NSA's Series A-1 Cumulative Redeemable Preferred Units.

The company disclosed that the rights, preferences, privileges, and voting powers of the newly issued PSA OP Series T and Series U Preferred Units remain materially unchanged from those held by the original NSA preferred unit holders. This preservation of terms protects the economic and governance interests of NSA's prior preferred security holders through the merger process. The creation of the Series T-1 Preferred Units represents additional preferred partnership interests that were designated as part of the amended partnership agreement to address the full scope of NSA's prior preferred unit structure.

Partnership Agreement Amendment and Preferred Unit Designation

On July 21, 2026, Public Storage's operating partnership entered into an amendment to its Amended and Restated Agreement of Limited Partnership specifically to designate the terms and conditions applicable to the newly issued preferred units. This PSA OP Agreement Amendment formally established the rights and preferences of the Series T, Series U, and Series T-1 Cumulative Redeemable Preferred Units. The disclosure indicates that the amendment process was necessary to integrate the preferred units into the operating partnership's governance structure while maintaining the substantive economic terms that preferred unitholders expected through the merger transaction.

The filing emphasizes that the designation of these preferred unit terms was executed with attention to preserving the economic arrangements that existed prior to the merger. By amending the operating partnership agreement to formally designate preferred unit terms that mirror the prior NSA preferred unit characteristics, Public Storage and its partners created a clear contractual foundation for the ongoing rights of these securities. This approach allowed for seamless integration of NSA's preferred capital into Public Storage's operating partnership structure without material disruption to preferred holder expectations or dividend payment obligations.

Dropdown Contribution and Financing Mechanics

The transaction documentation referenced a "Dropdown JV Contribution" in which NSA's operating partnership consummated a contribution transaction prior to the company-level merger. This contribution structure is commonly used in real estate investment trust acquisitions to segregate certain assets or refine the operating entity's capital structure before the primary merger steps occur. Following this dropdown contribution, Public Storage documented that a "Dropdown JV Financing" was subsequently consummated as contemplated in the transaction documents. Although the filing does not disclose specific details regarding the assets contributed or the financing amount, these mechanics represent standard acquisition structuring techniques that allow acquirers to optimize the combined entity's capital and operational configuration.

The coordination of the dropdown contribution, company merger, and financing activities required sequencing across multiple closing conditions and regulatory approvals. The fact that all these components closed successfully on July 22, 2026, indicates that the transaction parties completed all necessary prerequisites and obtained required consents from regulators and stakeholders. Investors should note that the specific terms of the financing arrangement and details regarding the contributed assets were not disclosed in this current report filing.

Public Storage Operating Partnership's Expanded Preferred Capital

Through the merger completion, Public Storage's operating partnership now carries a more extensive preferred unit structure that reflects both its historical preferred capital and the preferred interests received through the NSA acquisition. The company did not disclose in the filing the total number of Series T, Series U, or Series T-1 Preferred Units issued or their aggregate liquidation preferences. Prior to this transaction, Public Storage maintained multiple series of preferred shares and corresponding operating partnership preferred units, and this acquisition expands that preferred capital base while maintaining uniform distribution rates across the new preferred series at 6.000%.

The integration of NSA's preferred interests into Public Storage's operating partnership capital structure represents a significant addition to the company's preferred security holders. Investors in Public Storage's common shares should recognize that the preferred units carry senior rights to distributions and, in dissolution scenarios, senior claims to assets. The 6.000% distribution rate on the newly issued Series T and Series U Preferred Units reflects the current preferred capital market pricing environment and establishes the ongoing dividend obligation that Public Storage must maintain for these securities.

Regulatory and Closing Considerations

The filing confirms that Public Storage completed the National Storage Affiliates Trust acquisition on July 22, 2026, following execution of the core merger agreement on March 16, 2026. This approximately four-month period between signing and closing reflects the time necessary to obtain regulatory approvals, stockholder consents, and third-party authorizations that large real estate investment trust acquisitions typically require. The filing does not identify any conditions that remained unsatisfied or any regulatory limitations imposed on the transaction, indicating that all standard closing conditions were satisfied without material impediments.

Public Storage, organized as a Maryland real estate investment trust with principal executive offices in Frisco, Texas, maintains common share and multiple preferred share series listed on the New York Stock Exchange. The company's commission file number is 001-33519, and its IRS Employer Identification Number is 93-2834996. These organizational details remain unchanged through the NSA acquisition, as Public Storage functioned as the acquirer rather than the acquired entity in this transaction structure.

Securities Outstanding Following the Merger

Following the merger completion, Public Storage's publicly traded securities now include its common shares (ticker PSA) and an expanded roster of preferred share series. The company's disclosure lists preferred share series F through S, each representing 1/1,000 of a cumulative preferred share with varying dividend rates ranging from 3.875% to 5.600%. Additionally, Public Storage now has Series T and Series U Cumulative Redeemable Preferred Shares outstanding, each with a 6.000% distribution rate. The filing also indicates that Public Storage has guaranteed senior notes due in 2030, 2032, and 2034, with coupon rates of 0.500%, 0.875%, and 3.500%, respectively.

The company did not disclose in the filing the precise number of shares or units outstanding for each preferred series following the merger close, nor did it provide consolidated capitalization information showing the relative size of each preferred class. Investors seeking detailed information regarding preferred share counts, liquidation preferences, redemption rights, or relative seniority among the various preferred series should consult Public Storage's most recent quarterly or annual reports filed with the Securities and Exchange Commission.

Preferred Unit Rights Preservation Through Merger

The disclosure indicates that a central focus of the merger transaction involved ensuring that NSA's prior preferred unitholders retained materially equivalent rights and economic terms through the conversion process. By designating that the new PSA OP Series T and Series U Preferred Units would have rights, preferences, privileges, and voting powers that are "materially unchanged" from the NSA preferred units they replaced, Public Storage signaled its intent to honor the bargains struck with NSA's preferred capital holders. This approach is consistent with market standards for acquisition transactions involving senior or preferred securities, where acquirers typically preserve existing terms to avoid triggering change-of-control provisions or creating disputes with preferred security holders.

The creation of a Series T-1 Preferred Unit class alongside the Series T and Series U classes reflects the complexity of NSA's prior preferred unit structure and the precision required to ensure all prior preferred interests received appropriate conversion rights. While the filing does not specify the economic terms or preferences of the Series T-1 units beyond their designation in the partnership agreement amendment, their creation confirms that the transaction addressed all categories of NSA's prior preferred capital holders within a single comprehensive closing.

Merger Agreement Timeline and Execution

Public Storage and National Storage Affiliates Trust executed the merger agreement on March 16, 2026, establishing the legal framework for the transaction structure described in this current report. The April-to-July interval between signing and closing provided time for the parties to complete due diligence, obtain regulatory approvals, secure stockholder votes, and satisfy other customary acquisition conditions. The July 22, 2026 closing date marks the effective completion of the acquisition, at which point NSA ceased to exist as an independent entity and its assets, liabilities, and operations became integrated into Public Storage's structure.

The Merger Agreement was structured to involve both Public Storage and its operating partnership (PSA OP) as acquiring entities, with NSA and its operating partnership (NSA OP) as acquired entities. Wholly owned subsidiary entities Pelican Merger Sub I LLC and Pelican Merger Sub II LLC facilitated the actual merger transactions, with Merger Sub I (the company-level subsidiary) merging with NSA, and Merger Sub II (the partnership-level subsidiary) merging with NSA OP. This two-tier structure is typical for real estate investment trust acquisitions where both the corporate entity and the operating partnership must be combined to achieve the intended tax and operational outcomes.

Investor Considerations and Ongoing Obligations

Investors holding Public Storage common shares should understand that the NSA acquisition expands the company's asset base, operational footprint, and preferred capital obligations. The issuance of new preferred shares with a 6.000% distribution rate creates ongoing quarterly dividend obligations that Public Storage must satisfy from its operating cash flows. These obligations rank senior to common share distributions, meaning that preferred dividends must be paid before any distributions can be made to common shareholders. The integration of NSA's self-storage facilities into Public Storage's portfolio will influence future financial performance, occupancy rates, rental income, and operating expenses.

The merger completion does not itself disclose information regarding the total purchase price, financing structure, or expected financial impacts of the NSA acquisition. Investors seeking such information should review Public Storage's most recent earnings announcements, investor presentations, or quarterly financial reports. The company's ability to execute the complex multi-step transaction structure, including the dropdown contribution and subsequent financing, suggests that management successfully navigated the integration planning process, but detailed financial outcomes remain subject to market conditions and operational execution going forward.
