National Storage Affiliates Trust Announces Anticipated Closing Date of Pending Transaction; Declares Dividend in Connection with Pending Transaction

GREENWOOD VILLAGE, Colo.--(BUSINESS WIRE)--National Storage Affiliates Trust (“NSA” or the "Company") (NYSE: NSA) announced today that it expects the previously announced acquisition of NSA by Public Storage (the “Transaction”) to be completed on or about July 22, 2026 following the special meeting of NSA’s common shareholders on July 14, 2026. The completion of the Transaction remains subject to the approval of NSA’s common shareholders and other customary closing conditions.

On July 10, 2026, as contemplated by the merger agreement entered into in connection with the Transaction, the NSA Board of Trustees declared a special, prorated cash dividend of $0.0336 per common share (the “pro rata dividend”) for the period from and including July 1, 2026 through July 21, 2026, payable immediately before the consummation of the Transaction, to holders of record at the close of business on the business day immediately preceding the closing date of the Transaction and contingent upon the approval of the Transaction by NSA equity holders, the satisfaction or waiver of the other conditions to the Transaction and the merger agreement not having been terminated.

Based on the anticipated closing date of the Transaction of July 22, 2026, the pro rata dividend will be payable immediately prior to the completion of the Transaction on July 22, 2026 to the holders of record at the close of business on July 21, 2026.

If the closing date of the Transaction is delayed past July 22, 2026, holders of NSA’s common shares will not receive the pro rata dividend on July 22, 2026, and in such case NSA will make a public announcement providing further updates with respect to these matters.

Because the pro rata dividend payment will not be made if closing is delayed past July 22, 2026, The New York Stock Exchange (“NYSE”) has advised the NSA common shares will trade with “due bills” representing an assignment of the right to receive the distribution from the record date of July 21, 2026 up through the last day of trading on the NYSE (the “Due Bill Period”).

Holders who sell their NSA common shares during the Due Bill Period will be selling their right to the pro rata dividend payment, and such holders will not be entitled to receive the pro rata dividend payment. Due bills obligate a seller of NSA common shares to deliver the dividend payable on such NSA common shares to the buyer (the “Dividend Right”).

The dividend record date of July 21, 2026 will be used as the date for establishing the due bill tracking of the Dividend Right to the holder of NSA common shares. Due bill obligations are customarily settled between the brokers representing the buyers and the sellers of securities. The Company has no obligation for either the amount of the due bill or the processing of the due bill. Buyers and sellers of the NSA common shares should consult their brokers before trading to be sure they understand the effect of the NYSE’s due bill procedures.

Pursuant to the merger agreement, holders of NSA common shares will receive 0.14 of a Public Storage common share for each NSA common share they own immediately prior to the effective time of the Transaction and holders of NSA OP units will receive 0.14 of a common unit in Public Storage’s operating partnership (“Public Storage OP units”) for each NSA OP unit they own immediately prior to the effective time of the Transaction. Subject to and following the closing of the Transaction, former NSA common shareholders and NSA OP unitholders who become holders of Public Storage common shares or Public Storage OP units as a result of the Transaction will be eligible to receive dividends and/or distributions in respect of such Public Storage common shares and/or Public Storage OP units received as a result of the Transaction as and when declared by the Public Storage board of trustees, subject to holding such Public Storage common shares and/or Public Storage OP units as of the applicable record date for any such dividend or distribution.

NSA also announced that holders of a majority of the outstanding NSA OP units, excluding NSA OP units held, directly or indirectly, by NSA or any of its subsidiaries, consented to the Transaction pursuant to the consent solicitation conducted by NSA in connection with the Transaction. As a result, the approval of NSA’s common shareholders at the special meeting of NSA’s common shareholders on July 14, 2026 is the only remaining approval of NSA’s equity holders that is a condition to the completion of the Transaction.

For additional information regarding the proposed transaction, please consult the definitive proxy statement filed by NSA with the U.S. Securities and Exchange Commission on June 12, 2026.
