Executive Summary
If my company reprices my ISOs lower, are they still ISOs?
Sometimes—if the modification is structured to comply with ISO statutory requirements and is not treated as a new grant that breaks continuity rules. Many repricings effectively cancel and reissue awards; whether ISO status survives depends on facts and documentation. Assume nothing from the word “repricing” alone.
Do I owe tax when I accept an option exchange?
Often there is no immediate tax if you receive new options with continuity rules satisfied—but exchanges for RSUs or cash can trigger ordinary income at vest or payment. Read the offer: tax timing follows the instrument you receive.
What should I ask before consenting?
New strike price and share count, ISO vs NSO characterization, whether acceleration applies, whether new vesting cliffs were added, and whether any cash or RSU component is taxable immediately.
When stock drops, underwater options demotivate teams. Companies respond with repricings, exchange offers, or new grants. Each path has securities law, accounting, and tax layers—employees feel the tax layer in April.

Why Repricing Is Not “Free”
| Stakeholder | Concern |
|---|---|
| Company | Accounting charge, proxy disclosure, shareholder optics |
| Investors | Dilution and fairness vs new hires |
| Employees | ISO status, new vesting, tax timing |
ISO-Specific Risks
ISOs must satisfy grant, exercise, and holding rules. A modification that is treated as a new grant can:
- Restart holding clocks,
- Trigger $100K ISO limit issues,
- Convert tranches to NSOs if limits are exceeded.
Coordinate with a tax advisor before exercising repriced ISOs.
Exchange Offer Patterns
| Pattern | Sketch |
|---|---|
| Options for fewer options | Lower strike; fewer shares |
| Options for RSUs | Ordinary income at vest |
| Cash buyout of underwater options | Wage income |
Checklist
- Read the offer document and FAQ
- Model same-day sale vs hold if ISO status is unclear
- Compare to new-hire grants for fairness
- Confirm 409A support for new strike
