The email drops: "We're excited to announce that [Your Company] has filed for an initial public offering." Your heart races. You've been grinding for years with below-market salary, betting on this moment.
But then reality hits. When can you actually sell? What happens to unvested options? What's a lockup period? Why is everyone talking about 10b5-1 plans?
Going public changes everything about your equity—and if you don't understand the rules, you could miss out on life-changing wealth.
What Happens to Stock Options When My Company Goes Public?
The IPO doesn't automatically unlock your equity. What happens depends on what you hold.
For Stock Options (ISOs and NSOs)
Your options remain valid until expiration (typically 10 years from grant). But the IPO changes things:
Vesting continues: The IPO doesn't accelerate vesting unless your grant specifically includes IPO acceleration (rare).
Exercise becomes more attractive: Pre-IPO, exercising means tying up cash in illiquid stock. Post-IPO, you can exercise and immediately sell (cashless exercise).
409A valuations become public: The market now determines price daily, making option value transparent and volatile.
For Restricted Stock Units (RSUs)
Pre-IPO RSUs typically have double-trigger vesting:
- Trigger 1: Time-based (your normal schedule)
- Trigger 2: Liquidity event (IPO or acquisition)
Even if you hit your 1-year cliff pre-IPO, RSUs don't vest for tax purposes until the IPO occurs.
Tax surprise: All "time-vested" RSUs from years of pre-IPO work can vest within months after IPO, creating a massive tax bill. If you had 3 years of time-vested RSUs waiting, you could see hundreds of thousands in ordinary income hit your W-2 in one year.
Can I Sell Immediately After IPO?
Almost certainly not. Enter the lockup period.
What Is an IPO Lockup Period?
The lockup prevents insiders (including employees) from selling shares for 90-180 days post-IPO.
Why? If all employees sold immediately, the supply flood could crash the stock. Underwriters require lockups to stabilize the price.
Key details:
- Starts on IPO date, not when you joined
- Check your S-1 filing for exact expiration date
- Executives typically face longer lockups
After lockup expires, you still can't trade freely.
Blackout Periods and Trading Windows
Even post-lockup, companies restrict trading around earnings through blackout periods.
Most companies allow trading only during specific windows—typically a few weeks after quarterly earnings.
Example timeline:
- IPO: January 1
- Lockup expires: April 30
- Q2 earnings: May 5
- Trading window opens: May 10
- Your first sell opportunity: May 10 (4+ months after IPO)
How Does an IPO Affect Taxes?
For ISOs
Post-IPO, the calculus changes:
- FMV is publicly known (no more 409A estimates)
- AMT exposure is transparent based on current stock price
- Temptation to sell early is stronger—but costs you preferential tax treatment
For NSOs
Straightforward: ordinary income tax on spread at exercise, capital gains on appreciation after.
Post-IPO advantage: You know exactly what you'll pay because the price is public.
What New Benefits Do I Get?
Liquidity: Finally convert equity to cash for house, debt payoff, or diversification.
Price transparency: Track net worth in real-time instead of guessing from 409A valuations.
Tax planning tools: With liquid public stock, you can use tax-loss harvesting, charitable donations, and gifting strategies.
What New Restrictions Do I Face?
Insider Trading Rules
As an employee, you're an insider with material non-public information. Even if you think you don't have insider info, the SEC might disagree.
Solution: Set up a Rule 10b5-1 trading plan—a pre-scheduled plan that lets you sell automatically, providing legal protection.
Public Scrutiny
Every insider trade is public via Form 4. Colleagues can see when and how much you sell, creating awkward dynamics.
Volatility
Pre-IPO prices updated quarterly via 409A, usually trending up. Public prices change every second and can swing violently.
Your net worth might move $100,000 in a day. This volatility is stressful, especially when comp is equity-heavy.
How Should I Prepare Before IPO?
Map Out Your Equity
Track:
- Total options (vested and unvested)
- Strike prices and expiration dates
- Total RSUs (time-vested, waiting for liquidity)
- Estimated value at different prices
Model Tax Liability
Work with a tax professional to estimate your bill, especially if pre-IPO RSUs will vest post-IPO. You might owe six figures within months.
Build Cash Reserves
Plan to exercise options post-IPO? Start saving now. Even with cashless exercise available, you'll need cash for taxes if holding shares.
Set Up a 10b5-1 Plan
Consult legal and financial advisors to establish a Rule 10b5-1 plan before lockup expires. This allows systematic selling without insider trading concerns.
Create a Diversification Plan
Decide in advance what percentage you'll sell once lockup expires. Commit in writing. Otherwise, you'll make emotional decisions as the stock bounces.
Your IPO Game Plan
An IPO isn't a finish line—it's the start of a new financial planning phase.
Employees who build lasting wealth post-IPO sell systematically, diversify intelligently, and protect gains. They don't hold every share hoping for 10x returns.
Your company going public rewards years of hard work. Don't let confusion or misplaced loyalty cost you the financial security you've earned.
