- F1. In connection with the transactions contemplated by the Agreement and Plan of Merger, dated as of March 16, 2026 (the "Merger Agreement"), between the Issuer, Public Storage and certain other parties, each outstanding time-based long term incentive plan unit ("LTIP Unit") of NSA OP, LP (the "Partnership") that was granted to the Reporting Person in 2026 (such LTIP Units, the "2026 time-based LTIP Units") was converted on a one-for-one basis into an equal number of restricted common shares of beneficial interest, $0.01 par value, of the Issuer ("Restricted Shares").
- F2. Pursuant to the Merger Agreement, common shares of beneficial interest, $0.01 par value of the Issuer, inclusive of Restricted Shares, were converted into the right to receive 0.1400 (the "Exchange Ratio") newly issued common shares of beneficial interest, par value $0.10 per share, of Public Storage and cash in lieu of any fractional shares. Certain Restricted Shares were surrendered to satisfy statutory minimum federal and state tax obligations associated with the vesting.

Except as otherwise described above in Footnote 1 above with respect to the 2026 time-based LTIP Units, pursuant to the terms of the Merger Agreement, each outstanding and unvested LTIP Unit (other than performance-based LTIP Units granted in 2026) vested in full immediately prior to the effective time of the merger of a subsidiary of Public Storage into the Partnership (the "Partnership Merger"), with any applicable performance-based vesting conditions deemed achieved at target performance levels. Performance-based LTIP Units granted in 2026 and any performance-based LTIP Units that would only vest at maximum performance levels were deemed forfeited.
- F4. At the effective time of the Partnership Merger, each vested LTIP Unit that was eligible for conversion was converted into one Class A unit of limited partnership interest in the Partnership ("Class A OP Unit") in accordance with the Merger Agreement.
- F5. Pursuant to the Merger Agreement, each Class A OP Unit issued and outstanding immediately prior to the effective time of the Partnership Merger was (i) automatically converted into the right to receive a number of newly issued common units in Public Storage OP, L.P., equal to the Exchange Ratio or (ii), at the election of holders of Class A OP Units, redeemed in exchange for one newly issued unit in NSA OP JV, LLC which holds 80% of the equity of the joint venture with Public Storage that holds certain identified real estate assets contributed by the Partnership.

Agreement and Plan of Merger regulatory
"In connection with the transactions contemplated by the Agreement and Plan of Merger"
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
LTIP Unit financial
"each outstanding time-based long term incentive plan unit ("LTIP Unit") of NSA OP, LP"
An LTIP unit is a piece of long-term compensation granted to executives or employees that represents a right to future company value, paid in cash, stock, or stock-like units if certain performance goals or time-based vesting conditions are met. Investors care because LTIP units can dilute existing shares when converted to stock, signal how management is paid and incentivized, and affect future cash flow if settled in cash—think of them like delayed bonuses tied to company performance.
Class A OP Unit financial
"converted into one Class A unit of limited partnership interest in the Partnership ("Class A OP Unit")"
Exchange Ratio financial
"were converted into the right to receive 0.1400 (the "Exchange Ratio") newly issued common shares"
The exchange ratio is the number used to decide how many shares of one company you get for each share you own in another company during a merger or acquisition. It’s like a recipe that tells you how to swap shares fairly, ensuring both companies’ values are balanced. This ratio matters because it determines how ownership divides between the companies' shareholders.
