The 30-second read
Why it matters
NSA shareholders lose standalone rights; NSA common and preferred shares are delisted from NYSE and NSA requests suspension of Exchange Act reporting, while PSA issues consideration (PSA common and PSA preferred series).
Market read
This is a completed M&A close with delisting and reporting suspension, which can affect trading liquidity, conversion expectations, and investor positioning around PSA versus the now-defunct NSA listings.
What to watch
Former NSA preferred/common holders may face different PSA preferred series terms and cash-in-lieu mechanics, which can drive idiosyncratic flows not captured by PSA’s headline close.
