National Storage Affiliates Trust expects its $10.5 billion acquisition by Public Storage to close on or about July 22, 2026, following a special shareholder meeting on July 14, 2026, per NSA's July 10, 2026 Business Wire release. The board declared a prorated cash dividend of $0.0336 per common share payable immediately before closing. NYSE due bills will track the dividend right from the July 21, 2026 record date through the last trading day.
This is the operational finish line for the largest self-storage merger in history. Public Storage priced $900 million of senior notes on July 9, 2026 to fortify the balance sheet. NSA filed supplemental merger disclosures on July 8 addressing shareholder litigation. The July 10 release answers a different question: what happens to NSA shares, dividends, and unit holders in the final two weeks before close.
What Did NSA Announce on July 10, 2026?
NSA's July 10 release set three concrete dates and one dollar figure:
| Item | Detail |
|---|---|
| Shareholder vote | July 14, 2026 special meeting (virtual, 10:00 a.m. MDT) |
| Target close | On or about July 22, 2026 |
| Prorated dividend | $0.0336 per common share (July 1 through July 21, 2026) |
| Dividend record date | Close of business July 21, 2026 (if close proceeds on schedule) |
| Exchange ratio | 0.14 Public Storage share per NSA share |
The release also confirmed that holders of a majority of outstanding NSA OP units, excluding units held by NSA or its subsidiaries, had already consented to the transaction. Common shareholder approval at the July 14 meeting was the only remaining equity-holder condition.
NSA held 1,061 self-storage properties with approximately 69.3 million rentable square feet across 37 states and Puerto Rico as of March 31, 2026, per the release.
How Does the $0.0336 Prorated Dividend Work?
The dividend covers the period from and including July 1, 2026 through July 21, 2026. It is payable immediately before the merger consummates, contingent on:
- Shareholder approval of the transaction
- Satisfaction or waiver of other closing conditions
- The merger agreement not having been terminated
If closing delays past July 22, 2026, holders will not receive the dividend on that date. NSA committed to a public announcement with further updates if the timeline slips.
For context, this is a partial-month cash payment in a predominantly all-stock deal. It does not change the 0.14 exchange ratio. It addresses the gap between NSA's last regular distribution cycle and the merger effective time.
What Are NYSE Due Bills and Why Do They Matter?
Because the dividend payment is contingent on closing by July 22, the NYSE advised NSA common shares will trade with "due bills" during the period from the July 21, 2026 record date through the last day of trading.
Due bills work like this:
- A seller who disposes of NSA shares during the due bill period sells the right to receive the prorated dividend
- The buyer acquires that dividend right along with the shares
- Settlement occurs between brokers representing buyers and sellers
- NSA has no obligation for the due bill amount or processing
Buyers and sellers trading NSA shares between July 21 and close should consult their brokers before executing. The mechanics are standard for merger-related special dividends, but the timing is tight: three trading days between the record date and the target close.
What Equity Approvals Were Already Secured?
NSA cleared the OP unit consent solicitation before the July 14 common shareholder vote. That removed one major closing condition from the equity-holder side.
The common shareholder vote required affirmative approval from holders entitled to cast a majority of all votes entitled to be cast on the merger proposal, per NSA's definitive proxy filed June 12, 2026.
KSF opened a shareholder investigation on June 24, 2026 questioning process and price adequacy. NSA's July 8 supplemental disclosures addressed three lawsuits and published Morgan Stanley valuation materials. Legal friction did not pause the closing calendar.
What Happens to NSA Shareholders After Close?
Under the March 16, 2026 merger agreement:
- NSA common shareholders receive 0.14 Public Storage common shares per NSA share
- NSA OP unit holders receive 0.14 Public Storage OP units per NSA OP unit
- Former NSA holders who become Public Storage shareholders or unitholders become eligible for PSA dividends and distributions as declared, subject to applicable record dates
Post-close, Public Storage's U.S. market share moves from roughly 11% to more than 14%, per REITSWEEK's July 13 analysis of the financing stack. The combined entity will own or operate more than 4,500 facilities with nearly 330 million square feet.
NSA's final pre-merger acquisition was A-Plus Self Storage in Woodburn, Oregon for $9.5 million, a small tuck-in that closed while the merger timetable advanced.
What Should Operators Take From the July 22 Target?
Three sector-level signals.
First, the largest deal in self-storage history is entering its final two weeks. Competing buyers who expected merger delay to keep NSA properties off the market have a shrinking window.
Second, Public Storage is simultaneously closing a $1.2 billion Public Storage Canada acquisition and fortifying debt capacity. Scale buyers are not pausing for soft July street rates.
Third, the merger closes into a market where national street rates fell 2.4% month-over-month in July 2026. Synergy math matters more when organic growth is uneven. Public Storage's May 2026 operating update cited 320 basis points of churn improvement as evidence the combined platform can extract value even in a soft demand environment.
The Numbers Worth Writing Down
- Target close date: July 22, 2026
- Shareholder vote: July 14, 2026
- Prorated dividend: $0.0336 per common share (July 1 through July 21, 2026)
- Dividend record date: July 21, 2026 (contingent on timely close)
- Exchange ratio: 0.14 PSA share per NSA share
- Deal value at announcement: Approximately $10.5 billion (March 16, 2026)
- NSA portfolio (March 31, 2026): 1,061 properties, 69.3 million rentable square feet
- Post-close PSA U.S. market share: Roughly 14% (up from 11%)
- Remaining equity condition (July 10): Common shareholder approval only
The Calendar Is the Story Now
Announced in March. Financed in July. Voted on July 14. Targeted to close July 22. The NSA merger has moved from strategic headline to settlement mechanics: prorated dividends, due bills, OP consents, and a fixed exchange ratio into a $57 billion equity market cap REIT.
For every operator not named Public Storage or NSA, the question is what a 14% national market share incumbent does with PS4.0 operating priorities on day one. The answer starts July 22.
