ProMIS Neurosciences Inc. (PMN): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 1-for-25, first reflected in a filing dated 2026-03-25. 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.
