Increase in capital stock is the cash a company received during a period from issuing its own shares, including common and preferred stock sold in public or private offerings, shares issued when employees exercise stock options or buy through a stock purchase plan, and treasury shares reissued for cash. It is an inflow in the financing section of the cash flow statement.

Only cash proceeds count. Shares issued in exchange for a business, for services, or on conversion of debt are noncash transactions and do not appear here.

ASC 230 treats cash obtained from owners as a financing inflow. In XBRL, companies with one combined line use ProceedsFromIssuanceOrSaleOfEquity, which covers common and preferred stock, treasury stock, and option exercises. More specific elements break the total apart: ProceedsFromIssuanceOfCommonStock for offerings, ProceedsFromStockOptionsExercised for option exercises, and ProceedsFromIssuanceOfPreferredStockAndPreferenceStock for preferred issues. Proceeds are generally reported net of underwriting fees, though some companies show issuance costs as a separate outflow.

The size of this line depends heavily on the company's stage. For an established company it is often modest and made up mostly of employee option exercises and stock purchase plans. For a young or cash-burning company, follow-on offerings and at-the-market programs can make it the largest source of cash in the period. Shares issued as acquisition consideration never pass through the cash flow statement, so a company can issue a great deal of stock while reporting little here; the noncash disclosure and the statement of stockholders' equity show those issuances.

Analysts read this line against the share count. Cash raised by selling shares dilutes existing owners, so it is worth asking what the money funds and at what price it was raised. For companies that issue small amounts through employee plans while buying back larger amounts, it offsets part of the repurchase outflow and is best viewed alongside the decrease in capital stock.
