MID-AMER APT CMNTYS INC MAA
COM · REIT · CUSIP 59522J103 · ISIN US59522J1034
Real estate investment trust operating throughout the southeastern, southwestern, and mid-Atlantic United States
* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($97.7m this quarter). Holder counts are more reliable. Shares outstanding: 116.9m as of 2026-02-03, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $138.79. Options: 11 managers hold calls ($25.0m notional), 10 hold puts ($41.2m).

Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.
