How is a spin-off different from selling the company?

A spin-off distributes subsidiary ownership to shareholders (or related structures) rather than a classic third-party buyout—employee equity may split between parent and spun company.

Can ISOs remain ISOs in a spin-off?

They may if substitution or assumption satisfies continuity and Section 424-style tests—structure determines outcome.

When are RSUs taxed in a spin-off?

Generally when shares deliver and income is fixed—acceleration can move income earlier.

Should I read the merger agreement?

Yes—equity treatment is often detailed in transaction documents and plan amendments.

Where else is corporate equity covered?

See the stock options in M&A guide for assumption and substitution concepts.

Are spin-offs insider-trading sensitive?

Yes—new tickers and blackout windows may apply; coordinate with counsel on Rule 10b5-1 plans.
