Employee Equity at the IPO — What Happens to Options and RSUs

For employees with stock options or RSUs, the IPO is the event they have been waiting for. But the path from "equity on paper" to "cash in the bank" involves a lock-up period, tax planning, exercise timing decisions, and ongoing blackout period compliance. Companies that educate employees well before listing day experience significantly better outcomes than those that don't.

The Lock-Up Period

All insiders — officers, directors, and employees holding company stock or vested options — are subject to a lock-up agreement that prevents them from selling shares for a specified period after the IPO. Standard lock-up periods are 180 days, though some underwriting agreements use 90-day periods with an extension clause. The lock-up applies to:

• All shares currently held (including restricted stock, founder shares, and option shares already exercised)
• Shares received through option exercises during the lock-up period
• Shares received through RSU vestings during the lock-up period

After the lock-up expires, insiders can sell — but are still subject to: (1) quarterly blackout periods around earnings releases, (2) Rule 144 volume and manner-of-sale limitations for executives, and (3) Section 10(b)(5)-1 trading plan requirements for insider trading compliance.

Stock Option Tax Planning

The tax treatment of stock options at IPO depends on whether they are Incentive Stock Options (ISOs) or Non-Qualified Stock Options (NSOs):

Incentive Stock Options (ISOs)

• No regular income tax at exercise — but the spread (FMV at exercise minus strike price) is an Alternative Minimum Tax (AMT) preference item
• For high-value IPOs, the AMT hit from exercising ISOs can be substantial — employees may owe AMT of 28%+ on unrealized gains even before they can sell
• If stock is held 2+ years from grant date AND 1+ year from exercise date, proceeds are taxed at long-term capital gains rates (currently 15–20%)
• The $100K annual limit on ISOs that become exercisable in any year means options above that amount are automatically NSOs

Non-Qualified Stock Options (NSOs)

• The spread at exercise (FMV minus strike price) is ordinary income — taxed at rates up to 37% federal plus state income tax
• The company is required to withhold income and payroll taxes at exercise
• Simpler tax treatment but higher rates; executives with large option grants face significant ordinary income in the year of exercise

RSUs at the IPO

RSUs that vest at or after the IPO have straightforward tax treatment: the fair market value of the shares at vesting is ordinary income, and the company must withhold taxes. For RSUs vesting on the IPO date itself, the FMV is typically the IPO offer price. For RSUs vesting in the lock-up period, the FMV is the market price on the vesting date — which employees cannot immediately sell to fund the tax bill.

83(b) Elections — For Restricted Stock and Early Option Exercises

An 83(b) election allows employees or founders who receive unvested restricted stock (or who early-exercise unvested stock options) to pay income tax on the current FMV rather than the FMV at vesting. For early-stage companies where the stock is worth very little at grant, a timely 83(b) election can dramatically reduce lifetime tax liability by converting what would be future ordinary income into capital gain.

Critical facts about 83(b) elections:

• Must be filed within 30 days of the grant date. There are no extensions. Missing the deadline permanently forecloses this option.
• Election is made by filing a written statement with the IRS and retaining a copy. It must be attached to the tax return for the year of grant.
• For founders receiving restricted stock with a $0.0001 par value at incorporation, the tax cost of an 83(b) election is effectively zero — but the election must still be filed.
• For early option exercises, the 83(b) starts the capital gains holding period — relevant for ISO AMT planning.

Communicating Equity Value to Employees

The IPO process is an opportunity to reinforce employee ownership culture — and also to set accurate expectations. Companies that do this well:

• Provide employees with estimated vested equity value at a range of IPO price scenarios — not just the projected price
• Explain the lock-up mechanics clearly, including that vested options cannot be exercised and sold until after lock-up expiry
• Provide access to financial planning resources (many companies hire financial advisors to provide group education sessions)
• Explain blackout periods and insider trading compliance requirements that will govern trading after lock-up expiry
• Describe the mechanics of the equity administration platform (Carta, Shareworks, etc.) and how to execute transactions

Option Exercise Strategies Around the IPO

Employees with vested stock options face meaningful exercise timing decisions that affect both their tax bill and their post-IPO financial position. The key decision points:

• Early exercise before IPO (ISO strategy): Exercising vested ISOs before the IPO, while the 409A valuation is still low relative to the expected IPO price, minimizes the spread subject to AMT. If the employee holds the resulting shares for 1+ year from exercise and 2+ years from grant, the entire gain is taxed at long-term capital gains rates rather than ordinary income rates. The risk: the company might not achieve the anticipated IPO price.
• Exercise at IPO (same-day sale): Exercise and immediately sell enough shares to cover taxes — a "cashless exercise." This converts the option to cash in one step. The spread is ordinary income for NSOs; for ISOs, the spread is an AMT preference item in the year of exercise.
• Wait until after lock-up: Hold the options (do not exercise) until after the lock-up expires, then exercise and sell. This defers the tax event but means the employee bears stock price risk during the lock-up period on their paper gains.

ESPP — Employee Stock Purchase Plans at IPO

Many companies establish an Employee Stock Purchase Plan (ESPP) as part of the IPO equity program. An ESPP allows employees to purchase company stock through payroll deductions at a discount — typically 15% below the lower of the stock price at the beginning or end of the offering period (the "lookback" feature).

Key ESPP design decisions that are made before the first offering period:

• Offering period length: 6 months (common) or 12 months. Longer periods with more lookback periods create greater employee financial benefit but also greater company SBC expense.
• Discount percentage: The maximum for a Section 423 qualified ESPP is 15% — most companies use the full 15%.
• Purchase limit: The IRS limits ESPP purchases to $25,000 of stock per year (measured by the offering price, before the discount).
• Share reserve: ESPPs require a shareholder-approved share reserve — typically 1–3% of fully-diluted shares are reserved for the ESPP at IPO.

Communicating Equity Value Effectively

Companies that handle equity communications well before the IPO experience better employee engagement outcomes than those that leave employees to guess. A structured equity education program:

• IPO readiness briefing: A company-wide all-hands meeting 4–6 weeks before the anticipated IPO date explaining how equity plans work, what happens at IPO, and what the lock-up means in practical terms
• Individual equity statements: Providing every employee with a statement showing their specific vested and unvested equity, the strike price, and the implied value at a range of IPO price scenarios — not just the target price
• Access to financial advisors: Some companies partner with financial advisory firms to offer group seminars or one-on-one sessions for employees approaching significant liquidity events. The cost is modest relative to the goodwill generated and the tax errors prevented.
• Ongoing equity literacy: After the IPO, regular communications about blackout periods, 10b5-1 plan procedures, and Section 16 reporting requirements for officers prevent compliance violations that are embarrassing for both the employee and the company

Real-World Employee Equity Outcomes at IPO

The IPO is the defining moment for employee equity — but the outcomes vary enormously based on the company's valuation trajectory, the structure of equity grants, and post-IPO stock performance.

Airbnb — $2.8 billion in aggregate employee RSU value on Day 1 (December 2020): Airbnb's December 2020 IPO at $68 per share (opening at $146) created approximately $2.8 billion in stock-based compensation charges from the vesting of double-trigger RSUs at the IPO liquidity event. For individual employees, the outcomes depended heavily on hire date and grant timing: employees who had joined before 2018 and received early option grants at low strike prices saw the most dramatic returns, with some generating life-changing wealth. Employees who received grants at the last pre-IPO funding round valuation (at much higher prices) had more modest gains. The Airbnb IPO also involved a direct allocation of shares to Airbnb hosts — the people who listed their homes on the platform — as a gesture of community appreciation. Approximately 9.2 million shares were reserved for host purchases at the IPO price, a novel approach to aligning customer and shareholder interests.

Snowflake — options at $0.30 strike price, IPO at $120 (September 2020): Snowflake employees who received early option grants — some with strike prices as low as $0.30 per share — saw extraordinary returns when the company priced at $120 and subsequently traded at $245 on Day 1. A hypothetical employee with 10,000 options at $0.30 exercise price, selling on Day 1 at $245, would have realized approximately $2.45 million in pre-tax gains. The Snowflake case became a frequently cited example of how early equity in high-growth companies can create generational wealth for employees who joined before the company's inflection point and held through the IPO lock-up period.

WeWork — employee options became worthless (2019–2023): For WeWork employees who received stock options during the years when the company was valued at $10–$47 billion, the S-1 withdrawal and subsequent collapse of the business model was financially devastating. Options that had appeared to be worth millions based on the company's peak private valuation became worthless when WeWork filed for bankruptcy in November 2023. Some employees had made life decisions — buying homes, accepting lower salaries in exchange for equity — based on expected IPO wealth that never materialized. WeWork's employee equity outcome illustrates the most important risk in private company equity compensation: the value of unexercised options is entirely theoretical until a liquidity event occurs, and the liquidity event is not guaranteed.

Peloton — stock −90% from peak creates underwater options for late joiners (2021–2023): Peloton employees who received equity grants in 2020–2021 — when the stock was trading at $100–$171 per share — found themselves holding deeply underwater options by 2023, when the stock had fallen below $5. These employees had accepted below-market cash compensation in exchange for equity that they believed would be extremely valuable based on the company's COVID-era performance. The collapse of that equity value created significant retention challenges for Peloton: employees with underwater options have no financial incentive to stay, and the most talented individuals — who have the most external opportunities — are the first to leave. Peloton was forced to implement new equity grants at the lower stock price, effectively resetting the equity program for a depleted workforce.

Employee Equity at the IPO — What Actually Happened

Airbnb — $2.8 Billion in RSU Value, Day 1 (2020)

When Airbnb went public on December 10, 2020 at $68 per share (opening at $146), approximately 9,400 employees held RSUs that vested at the IPO under the double-trigger structure. The aggregate value of RSUs that vested on Day 1 was approximately $2.8 billion — one of the largest single-day employee equity realizations in IPO history. For senior employees who had joined Airbnb in its early years, the RSU grants represented life-changing wealth: a 2015 employee with 50,000 RSUs that vested at $146 received $7.3 million in pre-tax equity on a single day. The challenge for Airbnb's legal and HR teams was managing the withholding obligation — the company was required to withhold shares to cover income taxes on behalf of employees, and then remit cash to the IRS. Airbnb used a net settlement approach, withholding approximately 37% of each employee's vesting shares for federal and state income taxes, which meant selling those shares into the market on Day 1 and creating additional selling pressure on top of the normal IPO supply.

Snowflake — Options Granted at $0.30, Vested at $120+ (2020)

Snowflake employees who received option grants in the company's earliest years were holding instruments with a strike price as low as $0.30 per share when the IPO priced at $120. For those employees, each option had an intrinsic value of approximately $119.70 — a 39,900% gain on the strike price. The tax treatment of these options depended on whether they were ISOs (Incentive Stock Options, which receive favorable capital gains treatment) or NSOs (Non-Qualified Stock Options, which are taxed as ordinary income at exercise). Snowflake employees holding early-exercise ISO grants who had exercised and held for the one-year ISO holding period would have been eligible for long-term capital gains rates on the entire gain. Those with NSOs or those who exercised at the IPO would have faced ordinary income tax on the spread between strike price and fair market value — at the highest federal rate of 37% plus applicable state taxes, a significant cash tax obligation on the same day as the IPO.

WeWork — Options Became Worthless After S-1 Withdrawal

WeWork employees faced the inverse of the Airbnb and Snowflake experience. The company had granted options and RSUs to thousands of employees at strike prices and valuations reflecting the $47 billion private valuation — meaning employees expected significant wealth at an eventual IPO. When the S-1 was withdrawn in September 2019 and WeWork's valuation collapsed to approximately $8 billion in SoftBank's rescue financing, all options granted at strike prices above the new implied common stock value became deeply out of the money or worthless. Some employees who had exercised options early (under 83(b) elections) at high valuations were left holding illiquid shares worth a fraction of what they had paid in taxes at exercise. The WeWork story is a cautionary tale for employees evaluating equity compensation at highly-valued private companies: the path from a high private valuation to a successful liquidity event is not guaranteed, and early exercise at peak valuations creates real tax risk if the valuation subsequently falls.
