This section prints two different share counts. The weighted-average diluted count is the one in the table, the chart and the “Share count change” figure: it is the denominator of earnings per share and it moves with options, convertible securities, losses and timing as well as with shares issued or bought back. Period-end shares outstanding is the count on the last day of each financial year, and it is what the “buyback dollars per share actually removed” figure divides by. The two can move opposite ways in the same year. Neither of them can tell you whether your slice of the company grew or shrank, because these figures are stored as the company most recently filed them and a split is restated only into the earlier years a later filing presents: a three-for-two split raises a share count by half without changing a single holder's percentage, the series keeps that step wherever the restatement stopped, and nothing here separates it from shares genuinely issued. Nothing on this axis is therefore coloured green or red, and no ownership claim is made in either direction.

The baseline stays fixed, so a taller column means more shares on this basis than in the base year. It does not follow that each holder's slice got smaller: these counts are filed as reported, and a company that splits its stock restates only the earlier years its later filings present, so a taller column can be a split that changed nobody's ownership. The split is the share count's own rises and falls; SEC annual figures do not say which shares came from employee grants rather than an equity raise or an acquisition, so this chart does not claim to.
