How Does Vested Stock Work — Complete Guide

How does vested stock work

How does vested stock work is a practical question for anyone receiving equity as part of compensation. This article explains what "vested" and "unvested" mean, how common award types (stock options, RSUs, restricted stock) vest over time or on performance, and the tax, employment and liquidity implications you should expect. Reading this guide will help employees evaluate offers, help founders and HR design vesting schedules, and point to next steps including where to manage and trade shares using trusted platforms like Bitget and secure wallets like Bitget Wallet.

As of 2024-09-15, according to Carta reporting on equity trends, employer equity grants remain one of the primary tools startups use to attract and retain talent; that context frames why understanding how vested stock works matters for compensation decisions and liquidity planning.

Definition and Purpose of Vesting

Vesting is the process by which an employee earns the right to keep equity granted by an employer. "Vested" means the holder has an enforceable right to the shares or option benefits under the award terms; "unvested" means the award can be forfeited if conditions are not met. Companies use vesting for several reasons:

• Employee retention: vesting ties ownership to continued service.
• Incentive alignment: vesting rewards contributors who help grow value over time.
• Risk mitigation: employers avoid granting full ownership immediately, which helps protect the company if an employee departs early.

Understanding how vested stock works lets recipients know when they truly own equity versus when they have a conditional promise.

Types of Equity Awards Subject to Vesting

Stock Options (ISOs and NSOs)

Stock options give the holder the right to purchase company shares at a fixed strike (exercise) price for a defined period. Vesting determines when the option-holder can exercise that right. Key distinctions:

• Incentive Stock Options (ISOs): typically reserved for employees and can have favorable US tax treatment if holding requirements are met; they may trigger alternative minimum tax (AMT) at exercise in some cases.
• Non‑Qualified Stock Options (NSOs or NQSOs): taxed as ordinary income on the spread between exercise price and fair market value at exercise for US tax purposes; employers must withhold payroll taxes.

How vested stock works for options: until vested, you generally cannot exercise (unless the plan allows early exercise). Once vested, you may exercise subject to the award’s terms and any company restrictions.

Restricted Stock Units (RSUs) and Restricted Stock

RSUs are a promise to deliver shares (or cash equivalent) when vesting conditions are satisfied. No purchase is required for RSUs; at vesting the company issues shares or cash. Restricted stock refers to actual shares issued at grant but subject to repurchase or forfeiture until vesting.

How vested stock works here: for RSUs, vesting is the triggering event for delivery and taxable income recognition. For restricted stock, the recipient may hold legal title immediately but remains subject to forfeiture until vesting conditions lapse.

Other Award Types (ESPPs, Performance Shares, Phantom Stock)

• Employee Stock Purchase Plans (ESPPs): allow employees to buy shares at a discount, often with holding requirements; some ESPP discounts or purchases may be subject to vesting or offering period rules.
• Performance shares: vest only when company or individual performance targets are met (revenue, EBITDA, user metrics, etc.).
• Phantom stock: pays cash or equity based on company value changes; vesting controls when payouts occur.

All these award types answer the same question: when does the promise turn into enforceable ownership or economic value? That is the core of how vested stock works.

Common Vesting Mechanisms

Time-based Vesting

Time-based vesting is the most common. A typical schedule in tech startups is four-year vesting with a one-year cliff. Mechanics:

• Cliff: no vesting occurs until the cliff (commonly 12 months). If you leave before the cliff, you get nothing.
• Post-cliff: after the cliff, remaining vesting often accrues monthly or quarterly.

Example: 4-year vesting, 1-year cliff, monthly thereafter means 25% vests after 12 months, and the remaining 75% vests over 36 months monthly.

Cliff Vesting vs Graded/Ratable Vesting

• Cliff vesting: a large tranche becomes vested at once (e.g., 12-month cliff).
• Graded (ratable) vesting: small portions vest at regular intervals (monthly, quarterly, annually). Graded schedules give smaller, steady incentives.

Which to choose depends on retention goals and administrative simplicity.

Milestone/Performance-based Vesting

Performance-based vesting links vesting to measurable goals: revenue milestones, product launches, profitability, or individual KPIs. This ensures payoffs align with value creation but requires clear, verifiable metrics.

When considering how vested stock works with performance conditions, check definitional specifics: who measures performance, what timing governs outcomes, and what happens if metrics are partially met.

Hybrid and Reverse Vesting

• Hybrid vesting: combines time- and performance-based conditions (e.g., 50% time-based, 50% on performance targets).
• Reverse vesting: commonly used for founders; founders are issued shares upfront but the company has repurchase rights if vesting conditions fail. In substance, reverse vesting functions like time-based forfeiture protection for the company.

Acceleration Clauses

Acceleration clauses speed up vesting on specified events. Two common forms:

• Single-trigger acceleration: vesting accelerates upon a change in control (e.g., acquisition), regardless of employment status.
• Double-trigger acceleration: requires two events, commonly a change in control plus termination without cause or resignation for good reason within a set period.

Acceleration can be full or partial (e.g., 50% of unvested shares). Understanding how vested stock works for acceleration is crucial during negotiations for senior hires.

How Vesting Is Documented and Administered

Grant Notices and Award Agreements

The grant notice and award agreement set the rules: number of shares/options, vesting schedule, exercise window, repurchase rights, and tax withholding procedures. They are legally binding and define how vested stock works for each recipient.

Always read these documents carefully and keep a copy.

Plan Rules and Company Policies

The equity plan (the plan document) governs overall rules: eligibility, maximum pool, amendment procedures, and administrative authority. Plan rules can override certain expectations if awards reference the plan. Administration may include automated withholding, sell-to-cover, or brokerage-assisted exercises.

Companies often use equity administration platforms to track vesting and exercise status.

Exercising Options and Settlement of Awards

Exercising Vested Options (mechanics)

When you exercise vested options you buy shares at the strike price. Typical exercise methods:

• Cash exercise: pay the strike price in cash and receive shares.
• Cashless or broker-assisted exercise: use a broker to finance the purchase and simultaneously sell enough shares to cover costs and taxes (may be restricted in private companies).
• Net exercise: the employer issues fewer shares equal to post-tax net ownership.

How vested stock works in practice: you can only exercise vested options and must also observe the option’s expiration date.

Early Exercise and Buyouts

Some plans permit early exercise of unvested options. Early exercise allows purchasing shares before vesting but subjects them to repurchase/forfeiture rights; in the US, an 83(b) election may accelerate tax timing for restricted stock acquired this way.

Companies may also offer buyouts or cash settlements for vested or unvested awards in transactions.

Delivery and Sale of Shares

For RSUs, the settlement event typically issues shares or cash at vesting. For options, exercising converts the option into shares. Sale mechanics depend on company status:

• Public companies: shares can be sold on an open market after any lock-up or insider-trading windows.
• Private companies: sales require company consent, may face transfer restrictions, ROFR/ROFO, and often rely on sanctioned secondary markets.

Understanding how vested stock works for liquidity planning means checking both vesting and transferability rules.

Rights Before and After Vesting

Voting and Dividend Rights

Unvested awards typically do not carry full shareholder rights. Specifics:

• RSUs: generally do not convey voting rights until converted into shares at vesting, though some programs provide dividend equivalents.
• Restricted stock: may convey voting and dividend rights immediately but remain subject to repurchase until vested.

Check award documents to confirm rights during the unvested period.

Forfeiture and Repurchase Rights

Common outcomes when employment ends:

• Unvested awards: usually forfeited.
• Vested options: may be exercisable only for a short window after termination (commonly 90 days) unless extended by agreement.
• Company repurchase rights: for restricted stock or early-exercised options, companies often retain repurchase rights at the original purchase price if vesting hasn’t occurred.

How vested stock works around departures depends on the reason for leaving and the specific award provisions.

Tax and Accounting Implications

Note: tax and accounting rules vary by jurisdiction. The overview below focuses on typical US treatments to illustrate how vested stock works from a tax perspective. Always consult a tax advisor for personal situations.

Tax Treatment at Vesting vs Exercise vs Sale

• RSUs: taxable as ordinary income at vesting based on the fair market value of shares delivered; subsequent gains or losses on sale are capital gains/losses with holding period starting at vest date.
• NSOs: taxable as ordinary income on exercise to the extent the fair market value exceeds the strike price; further gain/loss on sale is capital in nature.
• ISOs: no regular income recognition on grant or exercise for regular tax (but exercise may trigger AMT); if holding requirements are met (2 years from grant and 1 year from exercise), qualifying disposition yields capital gains treatment.

How vested stock works tax-wise: different triggers (grant, vest, exercise, sale) create different tax events depending on award type.

Employer Withholding and Sell-to-Cover

Employers must generally withhold taxes at vesting or exercise for taxable awards. Common approaches:

• Sell-to-cover: employer arranges the sale of some shares to satisfy tax withholding.
• Net settlement: employer retains a portion of shares for taxes.

Understanding withholding rules is part of knowing how vested stock works in practice because taxes can materially affect your net proceeds.

Accounting (ASC 718, 409A, valuations)

In the US, employers account for equity awards under ASC 718, which requires recognizing compensation expense based on grant-date fair value. Private companies often obtain 409A valuations to set exercise prices for options. Incorrect valuations can create adverse tax consequences.

How vested stock works for employers: equity awards impact financial statements and require governance and valuation processes.

Employment Events and Their Effects on Vesting

Voluntary Resignation and Termination for Cause

If you leave voluntarily or are terminated for cause, companies commonly forfeit unvested awards. Vested options might have a limited window for exercise post-termination, often 90 days unless otherwise specified.

Termination Without Cause, Retirement, Disability, Death

Agreements may provide more favorable treatment for these events: extended exercise windows, accelerated vesting, or pro rata vesting to termination date. Some plans contain explicit provisions for death or disability vesting acceleration.

Change in Control, Mergers & Acquisitions

During a sale or merger, awards may be:

• Assumed or substituted by the acquirer.
• Cashed out for consideration (cash or stock) based on value at closing.
• Subject to acceleration (single- or double-trigger).

How vested stock works in transactions is often negotiated in sale agreements and plan terms; executives frequently negotiate robust change-in-control protections.

Liquidity, Transferability, and Market Constraints

Public vs Private Companies

• Public companies: once vested and free of insider/lock-up restrictions, shares are liquid and can be sold on public markets.
• Private companies: transfer restrictions often apply. Secondary markets exist but require company approval and buyer availability.

Understanding how vested stock works in terms of liquidity is essential for timing tax events and personal financial planning.

Lock-ups, Rights of First Refusal, and Transfer Restrictions

Even after vesting, contractual limits can affect transferability:

• Lock-ups: prevent sale for a period after an IPO.
• Rights of First Refusal (ROFR) / Rights of First Offer (ROFO): company may require first chance to buy shares on sale.
• Company consent: many private companies must approve transfers.

Check your award and company policies to know what you can actually sell when vested.

Designing Vesting Schedules: Employer Considerations

Common Practices and Benchmarks

Common benchmark schedules include:

• Early-stage startups: 4-year vesting with a 1-year cliff for employees; founders often have reverse vesting with shorter cliffs or bespoke terms.
• Later-stage companies: may shorten vesting or use performance-based elements for senior hires.

How vested stock works strategically: employers pick schedules to balance competitiveness, retention, and dilution.

Retention, Motivation, and Dilution Trade-offs

Longer vesting can improve retention but may weaken recruitment competitiveness. Aggressive acceleration reduces retention benefits and increases dilution. Employers should weigh these factors against company growth plans and capital needs.

Practical Examples and Calculations

Example Vesting Schedules (numeric)

Example A — Standard employee grant:

• Grant size: 4,800 options.
• Vesting: 4 years with 1-year cliff, monthly thereafter.
• Result: 1,200 options vest after 12 months (25%). Then 100 options vest each month for 36 months.

Example B — Founder reverse vesting:

• Founder granted 1,000,000 shares at issuance with a 4-year reverse vesting and 12-month cliff. If the founder leaves after 18 months, they keep 37.5% (450,000) and the remainder is subject to repurchase.

These examples show how vested percentages translate into actual share counts.

Tax Example Scenarios

High-level illustrations (US context):

• RSU: 1,000 RSUs vest when FMV is $10/share. You recognize $10,000 ordinary income at vest. If you sell later at $15, the $5,000 is capital gain.
• NSO: exercise 1,000 NSOs with $1 strike when FMV is $10. At exercise you recognize $9,000 ordinary income; sale later at $15 yields additional $5,000 capital gain.
• ISO: exercise 1,000 ISOs with $1 strike when FMV is $10. For regular tax, no immediate income (but AMT may apply). If you hold qualifying periods, sale at $15 gives capital gains treatment on $14 per share (difference between sale price and strike becomes capital gain, with special ISO rules).

These high-level examples illustrate how and when tax events occur and why planning matters.

Common Clauses, Risks and Pitfalls to Watch

Forfeiture Traps and Termination Timing

Watch for cliff timing and short post-termination exercise windows. Leaving days before a cliff can mean losing a significant portion of your grant. A short exercise window after termination can force expensive exercises or forfeiture.

Dilution, Repricing, and 409A Issues

Dilution from future grants can reduce ownership percentages. Repricing options can have tax and accounting consequences. Incorrect exercise prices relative to 409A valuations may trigger penalties or unfavorable tax outcomes.

Negotiation Levers for Employees

Potentially negotiable items:

• Shorter cliffs or faster vesting increments.
• Acceleration on change in control.
• Extended post-termination exercise windows.
• Protective covenants for key hires.

Understanding how vested stock works helps you identify which items to negotiate and why.

Frequently Asked Questions (FAQ)

Q: What happens if I leave before vesting?

A: Typically, unvested awards are forfeited. Check your award agreement for specific terms including any pro rata or accelerated vesting provisions.

Q: Can unvested shares be transferred?

A: Usually no. Unvested awards are conditional and typically non-transferable. Transfer rules are set out in the plan and award agreement.

Q: When do I pay tax?

A: It depends on award type: RSUs — at vest; NSOs — at exercise; ISOs — potential AMT at exercise and capital gains on qualifying disposition. Jurisdictions differ, so consult a tax professional.

Q: Can I exercise vested options in a private company?

A: Often yes, subject to company rules and funding. Selling the resulting shares may be restricted until liquidity events or approved secondary transactions.
