Summary

National Storage Affiliates Trust shareholders delivered overwhelming approval for the company's acquisition by Public Storage at a special meeting on July 14, 2026. With 99.9% of votes cast in favor and 84.6% of outstanding shares supporting the transaction, NSA cleared the final shareholder hurdle for the deal. The company expects to close the acquisition on or around July 22, 2026, subject to remaining customary conditions, at which point NSA will cease to exist as an independent public company.

While the merger vote was decisive, the advisory vote on merger-related executive compensation showed more resistance. With 14.4% of votes cast in opposition, shareholders expressed elevated concern about executive payouts tied to the transaction—higher than typical say-on-pay dissent but not enough to derail the deal. For NSA shareholders, the timeline is now clear: the transaction is on track to close within days, converting NSA shares into the agreed-upon Public Storage consideration.
