Union Pacific Corp (UNP): Shares Outstanding

Annual figures by period end, from SEC filings.

Stock splits: 2-for-1, first reflected in a filing dated 2014-07-25. 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.
