Shares of Stock

A share of stock (or simply “a share”) is the basic unit of equity ownership in a corporation. When an investor buys a share, they acquire a proportional claim on the company’s assets, earnings, and voting power (if the share class includes voting rights). One share of a company’s 1 million outstanding shares represents 1/1,000,000 of ownership. Shares can be common stock, preferred stock, or other classes depending on the rights and seniority they carry.

Fundamental characteristics

Ownership fraction: If a company has 10 million shares outstanding and you own 100 shares, you own 1% of the company (100 / 10,000,000).

Voting rights: Ordinarily, each share grants one vote in shareholder elections and major corporate decisions (assuming they are voting shares). Some shares, such as non-voting shares, carry no votes.

Dividend rights: Shareholders may receive dividends—periodic cash distributions—if the board declares them. Preferred shares usually have a stated dividend; common shares receive dividends only if declared.

Liquidation rights: In liquidation or bankruptcy, shareholders have a claim on the company’s assets after creditors and senior equity holders are paid. The order is: debt holders → preferred shareholders → common shareholders.

Par value: Each share has a stated par value (often $0.01–$1.00), which is a legal minimum price at issuance. Par value has little economic significance in modern practice.

Common vs. preferred shares

Common stock: The standard equity class, with ordinary voting and dividend rights. Common shareholders rank last in liquidation and have residual claims on company value.

Preferred stock: A senior class with stated dividends (usually fixed) and liquidation preferences. Preferred shareholders receive dividends before common and have priority in liquidation.

Most companies have one or more preferred classes (Series A, Series B, etc.) for investor rounds, with common shares for founders and employees.

How shares are created

Incorporation: When a company is founded, the charter specifies the authorized number of shares the company can issue (e.g., “10 million shares authorized”). This is an upper limit, not a commitment.

Issuance: The company’s board authorizes the issuance of a specific number of shares to founders, employees, or investors. Issued shares are now outstanding.

Multiple share classes: Many companies authorize multiple classes in the charter (Class A, Class B, etc.) with different voting rights or economic terms.

Buyback and treasury: If the company repurchases its own shares, those shares are held in treasury and are issued but not outstanding. Treasury shares do not vote or receive dividends. See treasury shares.

Share valuation

The market price of a share is determined by supply and demand. For public companies, the price is set by stock exchange trading. For private companies, valuation is often negotiated or determined by:

• Comparable company analysis: Valuing the company at a multiple of peers’ valuations.
• Discounted cash flow: Projecting future cash flows and discounting to present value.
• Recent fundraising rounds: The price per share in the most recent investor round.

A company with 10M shares and a valuation of $500M implies an intrinsic price of $50/share (though the actual market price may differ).

Dividends and earnings per share

Dividends: If the company distributes profit to shareholders, dividends are paid per share. A company with $10M in earnings and 10M shares outstanding has earnings of $1.00 per share (EPS).

Dividend per share: If the company declares a $0.50 annual dividend, each shareholder receives $0.50 per share held.

Retained earnings: If the company retains earnings rather than distributing them, shareholders benefit through capital appreciation if the retained capital is invested profitably. Common in growth companies.

Share transfer and ownership

Shares are transferable property. The owner can:

• Sell shares to other buyers (on public markets for traded companies, or privately for non-public companies).
• Gift shares to family members or charities.
• Pledge shares as collateral for loans.
• Hold shares indefinitely if there is no forced redemption or forced conversion.

Some shares have transfer restrictions:

• Restricted shares: Cannot be sold until vesting conditions are met.
• Lock-up periods: After an IPO, insiders often cannot sell for a period (typically 6 months).
• Registration rights: Some private shares can only be sold after registration or a public offering.

Authorized vs. issued vs. outstanding

• Authorized shares: The maximum number of shares the company can issue (set in the charter). Does not represent ownership.
• Issued shares: Shares that have been issued to investors, employees, or founders. Includes treasury shares.
• Outstanding shares: Issued shares minus treasury shares. These are the shares held by investors and in active circulation.

Example: A company authorizes 100M shares. It issues 50M to investors and employees. Later, it repurchases 10M for treasury. Outstanding shares = 50M - 10M = 40M.

Share splits and consolidations

Share split: The company increases the number of outstanding shares proportionally. A 2-for-1 split doubles the share count and halves the price per share. No economic change; purely a divisibility adjustment.

Reverse split: The opposite—consolidates shares. A 1-for-10 reverse split reduces the share count to 10% and increases the price per share by 10x.

Splits are cosmetic and do not affect ownership percentages or total market capitalization.

Dilution

Dilution occurs when the company issues new shares, reducing existing shareholders’ ownership percentage:

• Primary offering: The company issues new shares and raises capital.
• Secondary offering: Existing shareholders sell shares (no capital to the company, but increased float).
• Employee equity grants: The company issues restricted shares or options to employees.

A shareholder holding 10% of 10M shares owns 1M shares. If the company issues 5M new shares (raising capital), there are now 15M outstanding, and the shareholder’s 1M is now 6.67% (diluted).

Anti-dilution protections are negotiated by investors to mitigate this. See anti-dilution provisions.

Rights and responsibilities

Voting rights: Shareholders vote on major decisions (board elections, mergers, amendments to the charter) and can propose resolutions. Voting is typically one-share-one-vote, though super-voting shares may have greater influence.

Fiduciary duty: The board and management owe fiduciary duties to shareholders, requiring them to act in the company’s and shareholders’ best interests.

Liability limitation: Shareholders’ liability is usually limited to their investment (limited liability). If the company fails or faces a lawsuit, shareholders’ personal assets are protected.

No guaranteed returns: Stock ownership entitles shareholders to dividends (if declared) and residual claims in liquidation, but there is no guarantee of profit or principal recovery.

Market trading and valuation

For public companies, shares are traded on stock exchanges (NYSE, NASDAQ) and have transparent market prices. The price fluctuates based on:

• Company earnings and outlook: Better earnings or growth prospects increase share prices.
• Macroeconomic conditions: Recessions or interest rate changes can depress equities broadly.
• Sentiment and speculation: Investor sentiment, news, and momentum can temporarily inflate or deflate prices.

For private companies, shares are traded over-the-counter (if at all) and have no official price until an exit (IPO or acquisition).

Real-world example: Ownership scenarios

Scenario 1: An investor buys 1,000 shares of a company trading at $100/share. The investor has invested $100,000 and owns 1,000 / 1,000,000 outstanding = 0.1% of the company. If the company distributes a $1 annual dividend, the investor receives $1,000 (1,000 × $1). If the stock rises to $120, the investor’s position is now worth $120,000 (a $20,000 gain).

Scenario 2: A founder receives 1M shares (founder shares) at $0.01/share at the company’s inception. The founder owns 100% initially. When the company raises a Series A, investors buy 1M preferred shares at $10/share, valuing the company at $20M pre-money. Now there are 2M shares outstanding, and the founder owns 50%. The founder’s 1M shares are worth $10M (50% of $20M valuation).

Share class taxonomy

Companies can have many share classes, each with different rights:

• Class A: Super-voting, founder control
• Class B: Ordinary voting, investor shares
• Class C: Non-voting, public float
• Series A Preferred: Senior preferred, investor protection
• Series B Preferred: Junior to Series A, newer investor class

Each class is defined in the certificate of incorporation.
