Authorized Shares
Authorized shares are the maximum number of shares a corporation is legally permitted to issue, as specified in its articles of incorporation, setting an upper limit on how much equity it can create.
When a company is incorporated — most commonly in Delaware for large U.S. corporations — its founding documents (the certificate of incorporation) specify the maximum number of shares the company is authorized to issue. This number, the authorized share count, functions as a legal ceiling. The company cannot issue more shares than this limit without first amending its articles of incorporation, which typically requires a shareholder vote and a filing with the state of incorporation.
In practice, companies almost always authorize far more shares than they actually issue. Apple, for example, has authorized 12.6 billion common shares but has only a fraction of that number issued and outstanding at any time. This buffer of unissued authorized shares gives the board of directors flexibility to issue new shares for future needs — employee stock options and restricted stock units, follow-on public offerings, stock-based acquisitions, or dividend reinvestment plans — without going through the time-consuming process of amending the charter every time.
The relationship between authorized, issued, and outstanding shares matters for understanding a company's equity structure. Issued shares are the total shares that have been distributed to all shareholders, including shares the company has since repurchased (treasury stock). Outstanding shares are issued shares minus treasury stock — the shares actually in the hands of investors. Only outstanding shares count toward earnings per share, book value per share, and voting outcomes.
When a company wants to expand beyond its authorized count — for a major acquisition, for example — it must first obtain shareholder approval to increase the authorization. Shareholders scrutinize these requests carefully because expanding authorized shares creates the potential for dilution. Conversely, activist investors and governance advocates sometimes push for reducing the authorized share count if the board has long maintained a large unused authorization that could be used to entrench management or frustrate takeover attempts through share issuances to friendly parties.
On SEC filings, companies are required to disclose their total authorized, issued, and outstanding share counts in the equity section of the balance sheet and in the notes to their financial statements. Changes to authorized share counts appear in 8-K filings and are voted on through the proxy process, keeping shareholders informed of any proposed alterations to the company's capital structure.
