Risks Relating to the Mergers

Current report

Failure to complete the pending Mergers could have an adverse effect on us.

Current report

If the Mergers are not completed, our business, financial condition, results of operations and growth

Current report

prospects may be adversely affected and, without realizing any of the benefits of having completed the Mergers, we will be subject to a number of risks, including the following:

Current report

•the market price of our common shares or preferred shares could decline;

Current report

•we will have incurred substantial costs relating to the Mergers, such as legal, accounting, financial advisor, filing, printing and mailing fees and integration costs that have already been incurred or will continue to be incurred until the closing of the Mergers, which could adversely affect our business, financial condition, results of operations and growth prospects;

Current report

•we could be subject to litigation related to any failure to complete the Mergers or related to any enforcement proceeding commenced against us to perform our obligations under the Merger Agreement;

Current report

•we will not realize the benefit of the time and resources, financial and otherwise, committed by management to matters relating to the Mergers that could have been devoted to pursuing other beneficial opportunities; and

Current report

•we may experience reputational harm due to the adverse perception of any failure to successfully complete the Mergers or negative reactions from the financial markets or from our customers, vendors, employees and other commercial relationships.

Current report

Any of these risks could adversely affect our business, financial condition, results of operations and growth prospects. Similarly, delays in the completion of the Mergers could, among other things, result in additional transaction costs, loss of revenue or other negative effects associated with delay and uncertainty about completion of the Mergers and could adversely affect our business, financial condition, results of operations and growth prospects after the Mergers.

Current report

We may not realize the anticipated benefits and synergies from the pending Mergers.

Current report

The Mergers involve the combination of two companies that currently operate as independent public companies. While we and NSA will continue to operate independently until the completion of the Mergers, the success of the Mergers will depend, in part, on our ability to realize the anticipated benefits from successfully combining our and NSA’s businesses. We plan on devoting substantial management attention and resources to integrating our and NSA’s business practices and operations so that we can fully realize the anticipated benefits of the Mergers. Nevertheless, the business and assets acquired may not be successful or continue to grow at the same rate as when operated independently or may require greater resources and investments than originally anticipated. The Mergers could also result in the assumption of unknown or contingent liabilities. Potential difficulties we may encounter in the integration process include the following:

Current report

•the inability to successfully combine the business of NSA with ours in a manner that permits us to achieve the cost savings anticipated to result from the Mergers, which would result in some anticipated benefits of the Mergers not being realized in the time frame currently anticipated or at all;

Current report

•the failure to integrate operations and internal systems, programs and controls;

Current report

•the inability to successfully realize the anticipated value from some of NSA’s assets;

Current report

•lost sales, loss of customers, joint venture partners and other commercial relationships;

Current report

•the complexities associated with managing the combined company, including the complexity of managing the newly formed JV;

Current report

•the additional complexities of combining two companies with different histories, cultures, markets, strategies and customer bases;

Current report

•the failure to retain key employees of either of the two companies that may be difficult to replace;

Current report

•the disruption of each company’s ongoing businesses or inconsistencies in services, standards, controls, procedures and policies;

Current report

•potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the Mergers; and

Current report

•performance shortfalls at one or both of the two companies as a result of the diversion of management’s attention caused by completing the Mergers and integrating NSA’s and our operations.

Current report

Any of these risks could adversely affect our ability to maintain relationships with customers, vendors, employees and other commercial relationships. As a result, the anticipated benefits of the Mergers may not be realized fully within the expected time frame or at all or may take longer to realize or cost more than expected, which could adversely affect our business, financial condition, results of operations and growth prospects. In addition, changes in laws and regulations could adversely impact our business, financial condition, results of operations and growth prospects.

Current report

We expect to incur substantial expenses related to the Mergers.

Current report

We expect to incur substantial expenses in completing the Mergers and integrating the business, operations, practices, policies and procedures of NSA. While we have assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond our control that could affect the total amount or the timing of integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. The expenses in connection with the Mergers are expected to be significant, although the aggregate amount and timing of such charges are uncertain at present.

Current report

Following the Mergers, we will have a substantial amount of indebtedness and may need to incur more in the future.

Current report

Our total indebtedness as of March 31, 2026 was $10.1 billion. This amount excludes the outstanding indebtedness of NSA, which may be repaid or remain outstanding (or a combination thereof) in connection with the Mergers. The instruments governing our existing indebtedness permit us to incur substantial additional debt, including secured debt, and we may satisfy its capital and liquidity needs through additional borrowings. A high level of indebtedness would require us to dedicate a substantial portion of our cash flow from operations to the payment of debt service, thereby reducing the funds available to implement its business strategy and make distributions to our shareholders. A high level of indebtedness on an absolute basis or as a ratio to its cash flow could also have the following consequences:

Current report

•potential limits on our ability to adjust rapidly to changing market conditions and vulnerability in the event of a downturn in general economic conditions or in the real estate industry;

Current report

•potential impairment of our ability to obtain additional financing to execute on our business strategy; and

Current report

•potential downgrade in the rating of our debt securities by one or more rating agencies, which could have the effect of, among other things, limiting our access to capital and increasing its cost of borrowing.

Current report

In addition, from time to time, NSA and we mortgage certain of their properties to secure payment of indebtedness. If we are unable to meet its mortgage payments, then the encumbered properties could be foreclosed upon or transferred to the mortgagee with a resulting loss of income and asset value.

Current report

Completion of the Mergers is subject to many conditions, and if any of these conditions are not satisfied or waived, the Mergers may not be completed on the currently contemplated timeline or terms, or at all.

Current report

The consummation of the Mergers is subject to the satisfaction or waiver of certain conditions, including among others: (i) approval of the NSA Merger by NSA’s shareholders; (ii) approval of the Mergers and the other transactions contemplated by the Merger Agreement by holders of NSA OP Units; (iii) the effectiveness of a registration statement on Form S-4 filed by us becoming effective in accordance with the provisions of the Securities Act; (iv) the absence of a law or order restraining, enjoining, rendering illegal or otherwise prohibiting the consummation of the Mergers; and (v) the common shares and the preferred shares of the Company to be issued in the Mergers being approved for listing on the New York Stock Exchange, (vi) the newly formed JV having been formed and (vii) other customary conditions. We cannot provide assurance that the conditions to completing the Mergers will be satisfied or waived, and accordingly, that the Mergers will be completed on the terms or timeline that the parties anticipate or at all. If any condition to the Mergers is not satisfied, it could delay or prevent the Mergers from occurring, which could negatively impact the price of our common shares and preferred shares and our business, financial condition, results of operations and growth prospects, including incurring significant acquisition costs that we would be unable to recover, negative publicity and a negative impression of us in the investment community.

Current report

Holders of our common shares will be diluted by the Mergers, if consummated.

Current report

The Mergers will dilute the ownership position of holders of our common shares. Consequently, our holders of common shares, as a general matter, will have less voting control and influence over our management and policies after the effective time of the Mergers than they currently exercise over our management and policies.

Current report

An adverse outcome in any litigation or other legal proceedings relating to the Merger Agreement, or the transactions contemplated by the Merger Agreement, could have a material adverse impact on our business and our ability to consummate the Mergers.

Current report

Transactions like the Mergers are frequently the subject of litigation or other legal proceedings, including actions alleging that either party’s board of trustees breached its respective duties to its shareholders or other equityholders by entering into a merger agreement, by failing to obtain a greater value in a transaction for its shareholders or any other claims (contractual or otherwise) arising out of a merger or the transactions related thereto. An adverse outcome in such matters, as well as the costs and efforts of a defense even if successful, could have a material adverse impact on our ability to complete the Mergers or their respective businesses, financial conditions, results of operations and growth prospects, including through the possible diversion of either company’s resources or distraction of key personnel.
