Martin Marietta Materials  (MIL:1MLM) Shares Outstanding (EOP) Explanation

A company may buy back shares or issue shares in any fiscal period. If a company buys back shares, we should observe that the total number of shares decline. If the company issues new shares, the number of shares outstanding increases.

Usually the presence of treasury shares and a history of buyback are good indicators that company has competitive advantage. But studies have shown that companies usually buy back at wrong time. Buying back shares below its intrinsic value increases value for remaining shareholders. Buying back overvalued shares destroys value for existing shareholders.
