Are repriced ISOs still ISOs?

It depends on whether the modification is structured to preserve ISO status under IRC Sections 422 and 424. Many programs cancel and reissue awards—do not assume ISO continuity without documentation.

What is an underwater option?

An option whose strike price exceeds the stock’s fair market value—no intrinsic value until repriced or until the stock recovers.

Does repricing affect the $100K ISO limit?

Potentially—new grants or deemed new grants can change which tranches count as ISO vs NSO.

Should I compare to M&A assumptions?

Yes—Section 424 substitution concepts overlap with corporate transaction treatment.

Who approves repricings?

Typically the board of directors; public companies may need shareholder approval under exchange rules.

Stock Option Repricing & Exchange Offers: Tax, ISO Status & What Employees Should Ask

Q: Do I owe tax when I accept an option exchange?

Often not immediately for option-for-option exchanges that qualify—exchanges for RSUs or cash can trigger ordinary income at vest or payment. Read the offer.

Key Takeaways

A repricing often counts as cancelling old options and granting new ones—ISO status is at risk if rules aren’t met

Exchange offers may swap options for RSUs or fewer shares—economic and tax profiles change

Underwater options have no intrinsic value until repriced or until stock recovers

Board approval and shareholder approval may be required—timeline affects your election window

409A still requires reasonable FMV methodology for new strikes or RSU grants
