Outset Medical, Inc. (OM): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 1-for-15, first reflected in a filing dated 2025-05-08. 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 2023-12-31 is not shown: shares outstanding out of scale with weighted shares. That usually means the filing tagged the figure in the wrong unit.
