Innovative Industrial Properties Inc (IIPR): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 3-for-2, first reflected in a filing dated 2020-05-07. Figures are as filed: per-share figures and share counts last reported before a split are on the old share basis, so changes and growth rates across a split are not shown. Splits are read from the filings' own restatements, so a share conversion in a merger or reorganization shows up the same way.

Figures left out. The filed Shares Outstanding for the year ended 2016-12-31 is not shown: zero share count.
