What Is Equity in Business?
Equity represents ownership in a company. When you hold equity, you have a stake in the business's success, with rights to share in its profits and potentially influence its direction. Understanding equity is fundamental whether you're a founder building a company, an employee evaluating compensation, or an investor looking to participate in growth.
The basic accounting formula captures equity's essence: Assets minus Liabilities equals Equity. This represents what would remain for owners if all company assets were sold and all debts paid. But in practice, equity is far more than a balance sheet figure--it serves as the primary mechanism for aligning interests between founders, employees, and investors. When you own equity, you gain legal claims on the company's assets and future earnings, creating a direct connection between your personal success and the company's trajectory.
For founders, equity represents the fruits of their entrepreneurial vision and the capital they've invested in building something meaningful. Employees receive equity as a form of compensation that rewards them for their contributions to company growth, aligning their incentives with long-term success. Investors provide capital in exchange for ownership stakes, betting that the company will grow and their equity will appreciate significantly over time. Each stakeholder group views equity differently, but all share a common interest in the company's prosperity. Understanding these perspectives helps you navigate negotiations, compensation packages, and investment decisions with confidence.

Types of Equity: Common Shares and Preferred Shares
Companies primarily issue two types of equity: common shares and preferred shares. Each carries different rights and serves different purposes within a company's ownership structure.
Understanding the differences helps you navigate ownership structures
Common Shares
Basic ownership units representing residual claim on company assets and earnings. Typically issued to founders and employees, with voting rights attached.
Preferred Shares
Equity with preferential treatment including liquidation preferences and dividend priority. Typically issued to investors in funding rounds.
Common Shares
Common stock represents the most basic form of ownership in a corporation. When a company is incorporated, it creates common shares that represent fractional ownership in the business. Common shareholders have the right to vote on corporate matters such as board elections and major transactions, typically receiving one vote per share. This voting power allows common shareholders to influence company direction and hold management accountable.
Beyond voting rights, common shareholders hold residual claims on company assets. This means they receive whatever remains after all debts and preferred shareholder claims are satisfied. While this positions them last in line during liquidation, it also means they participate fully in upside potential--unlike preferred shareholders whose returns are often capped. Common shareholders may receive dividends when the board declares them, though companies are not obligated to pay dividends and often reinvest profits to fuel growth.
Founders and employees primarily receive common shares because they take on the residual risk and reward of the business. When common shares are issued, ownership percentages are calculated by dividing an individual's share count by the total outstanding shares. This percentage determines voting power and proportional entitlement to distributions. As companies raise funding and issue new shares, existing common shareholders may experience dilution unless they participate in pro-rata rounds. Understanding how these calculations work is essential for anyone receiving equity compensation, as it directly impacts the value of your stake in the company's future success.
Preferred Shares
Preferred stock includes additional rights and protections that make it attractive to investors. The most significant is the liquidation preference, which ensures investors receive their money back (often with a multiple) before common shareholders receive anything. A typical 1x non-participating liquidation preference means investors get their original investment back before common shareholders participate in remaining proceeds. Some investors negotiate participating preferred, which allows them to receive their liquidation preference AND share in remaining proceeds--a structure that can significantly affect payout distributions during exits.
Preferred shareholders typically receive priority in dividend payments and may have anti-dilution protections that adjust their ownership stake if the company raises future rounds at lower valuations (a "down round"). These protections, such as broad-based weighted average adjustment, prevent significant dilution from subsequent funding rounds at lower prices. Many preferred shares include conversion rights allowing them to become common shares, typically at the investor's election during liquidity events. This conversion right lets investors choose the structure that maximizes their return based on the exit scenario.
Venture capital and angel investors receive preferred stock because these instruments protect their substantial capital investments while preserving upside potential. When negotiating term sheets, investors focus heavily on liquidation preferences, dividend rates, anti-dilution provisions, and board composition rights. Understanding these terms helps founders evaluate investment offers and negotiate favorable conditions. According to Carta's comprehensive analysis of equity structures, the balance between investor protections and founder incentives shapes every funding round negotiation.

Employee Equity: Stock Options, RSAs, and RSUs
Equity compensation allows companies to attract, retain, and motivate talent by offering ownership stakes. Understanding the different instruments helps both employers design effective programs and employees evaluate compensation packages.
| Feature | Stock Options (ISO/NSO) | Restricted Stock Awards (RSA) | Restricted Stock Units (RSU) |
|---|---|---|---|
| Ownership at Grant | Right to purchase shares | Yes (subject to vesting) | No (promise of future shares) |
| Exercise Required | Yes - pay strike price | No | N/A - shares delivered |
| Tax Timing | At exercise (NSO) or disposition | At vesting | At vesting |
| Best For | Early-stage, growth companies | Early employees, low FMV | Later-stage, stable companies |
| Risk to Employee | Upfront cost + uncertainty | Tax at vesting | Value at vesting only |
Understanding Stock Options
A stock option gives the holder the right, but not the obligation, to purchase company shares at a fixed price (called the strike price or exercise price) for a specified period. The key advantage is that employees benefit from stock price appreciation without having to invest capital upfront. Options represent the potential for ownership rather than actual ownership, making them particularly valuable in high-growth companies where future value is expected to exceed current levels.
The strike price is typically set at the Fair Market Value (FMV) of the stock on the grant date. For private companies, FMV is determined through a 409A valuation conducted by an independent appraiser. This valuation establishes the exercise price and affects the potential spread between what employees pay and what their shares might be worth in the future. If the company's value increases over time, the spread between the current value and strike price represents potential profit--employees who exercise their options and hold the shares can benefit from this appreciation when liquidity arrives.
Incentive Stock Options
ISOs offer potential tax advantages for employees. They qualify for special tax treatment where regular income tax isn't due at exercise (though AMT may apply). To receive favorable treatment, shares must be held for specified periods after exercise--the "qualified disposition" rules require holding for at least two years from grant and one year from exercise.
Key Characteristics:
- Available only to employees (not contractors or advisors)
- No regular income tax at exercise (Alternative Minimum Tax may apply)
- Long-term capital gains treatment on appreciation if qualified disposition rules met
- $100,000 ISO limit per year (value of vesting shares calculated at grant)
The $100,000 limit applies to the fair market value of shares that vest during any calendar year. Any ISOs exceeding this limit are treated as NSOs for tax purposes. For employees whose ISO grants exceed this threshold, careful planning is essential to understand which options receive preferential tax treatment.
ISOs are most beneficial for employees who plan to stay with their company long enough to meet qualified disposition requirements and who have the financial capacity to exercise options without requiring immediate liquidity. The tax advantages can be substantial--employees can potentially realize significant gains taxed at long-term capital gains rates rather than ordinary income rates. However, the complexity of ISO rules and AMT implications means employees should consult tax advisors before making exercise decisions.
Restricted Stock Awards (RSAs) and Restricted Stock Units (RSUs)
Unlike options, restricted stock represents actual ownership (RSAs) or a promise of ownership (RSUs) that vests over time. These instruments are commonly used as companies mature and move beyond early-stage growth phases where options are more typical.
Restricted Stock Awards grant shares immediately upon issuance, subject to vesting conditions that typically follow the standard four-year schedule with a one-year cliff. If the employee leaves before fully vesting, the company can repurchase unvested shares at the original purchase price (often par value). RSAs can be subject to an 83(b) election, allowing recipients to be taxed at grant rather than vesting. This election is particularly valuable when the stock's current value is low relative to its potential future value, as it lets employees lock in lower taxable income now while deferring tax on future appreciation.
Restricted Stock Units represent a promise to deliver shares once vesting conditions are met. Unlike RSAs, no actual shares exist until vesting, so there's no 83(b) option available. The value of RSUs is simply the number of units times the stock price at vesting, making their worth more predictable and easier to communicate to employees. RSUs are popular among later-stage companies because they're easier to administer and offer more predictable value to employees who may be more risk-averse than early-stage joiners.
The choice between RSAs and RSUs depends on company stage, valuation stability, and employee population characteristics. Early-stage companies with significant growth potential often favor options because they offer asymmetric upside potential with limited downside risk for employees. More mature companies with predictable valuations frequently use RSUs because they provide tangible value that employees can more easily understand and plan around.

Vesting: Earning Your Equity Over Time
Vesting ensures equity recipients earn their shares progressively over time, protecting both the company and the recipient. Without vesting, an employee could receive all their shares and leave immediately, leaving the company without recourse and wasting equity that could have attracted and retained other talent.
The standard vesting schedule in the startup world is four years with a one-year cliff. This means no shares vest during the first year (the cliff), and then shares vest monthly over the remaining three years. If an employee leaves before the cliff, they receive nothing--this protects the company from investing in talent that doesn't stick around. After the cliff, the monthly vesting creates ongoing incentive to remain with the company.
This structure aligns incentives: employees are motivated to stay and contribute, knowing they earn their equity progressively, while companies retain flexibility during the critical early period when they're evaluating team members and culture fit. For employees, vesting creates a personal stake in the company's success that grows stronger over time, encouraging long-term thinking and commitment.
Cliff Period
Initial period (typically one year) during which no equity vests. Leaving before the cliff means forfeiting all equity.
Monthly Vesting
After the cliff, shares typically vest monthly over the remaining years (e.g., 1/48 per month for a 4-year grant).
Acceleration
Provision that speeds up vesting upon certain events like acquisition (single trigger) or termination (double trigger).

Equity only becomes valuable when it can be converted to cash through a liquidity event. Understanding these events helps set realistic expectations about when and how equity might pay off, and what factors influence the ultimate value realized.
Initial Public Offering (IPO) is when a private company first offers shares to the public through listing on a stock exchange. The transition from private to public creates the first real opportunity for most equity holders to convert their ownership into liquid assets. After the lock-up period (typically 90-180 days), employees and other shareholders can sell their shares on the open market. The value realized depends on the public market price at sale, which is determined by investor demand and company performance.
Mergers and Acquisitions (M&A) occur when another company purchases the business, providing a liquidity event for shareholders. In acquisitions, shareholders receive payment according to their preferences--preferred shareholders first (up to their liquidation preference), then common shareholders receive any remaining proceeds. The structure of the acquisition and the terms of the preferred stock significantly impact what common shareholders ultimately receive. Understanding the waterfall distribution is essential for setting realistic expectations.
Secondary Transactions allow private company shareholders to sell to other investors before an IPO. These can take the form of tender offers (company-facilitated sales where the company invites shareholders to sell to identified buyers) or direct transactions between parties. Secondary markets have grown significantly, providing earlier liquidity opportunities for employees and early shareholders. However, these transactions often come with restrictions and may offer prices different from the company's most recent 409A valuation.
Company Buybacks occur when the company purchases shares from employees or other holders, providing liquidity without an acquisition. Companies may implement share repurchase programs to give employees liquidity, reduce outstanding shares, or prevent unwanted ownership concentrations. The pricing and availability of buybacks depend on company policy and financial capacity.
Each liquidity event type creates different outcomes for equity holders based on their class of stock and the specific terms governing their securities.

Equity in Different Business Structures
The form equity takes depends on the business entity type. C-corporations and LLCs handle ownership differently, with implications for how equity is issued, taxed, and transferred. Choosing the right structure early in a company's lifecycle can significantly impact future flexibility and the ability to attract investment.
C-Corporations are the standard choice for venture-backed startups. They issue shares of stock (common and preferred), allowing clear ownership tracking and enabling venture investment through preferred stock arrangements that investors expect. C-corps face double taxation on corporate profits and dividends--profits are taxed at the corporate level when earned, and dividends are taxed again at the shareholder level when distributed. Despite this tax burden, the C-corp structure accommodates the preferred stock and option arrangements that venture investors require, making it the default choice for companies seeking institutional funding.
Limited Liability Companies (LLCs) use membership interests rather than shares. Profits interests are the common equity compensation tool, giving recipients a stake in future appreciation without immediate ownership interest in the LLC's capital. LLCs offer pass-through taxation where profits and losses flow through to members' personal tax returns, avoiding double taxation. However, LLCs can complicate venture investment, which traditionally expects C-corp structures with clear share classes and standardized investor rights. While some investors will invest in LLCs, many prefer the familiar territory of C-corp equity.
The choice between C-corps and LLCs depends on factors including fundraising goals, team composition preferences, and tax planning considerations. Founders planning to raise venture capital typically incorporate as C-corps from the start, while service businesses or lifestyle companies may benefit from LLC simplicity and pass-through taxation. Our corporate structuring services can help you evaluate the best approach for your specific situation and establish the appropriate entity structure from the beginning.
