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.

Executive Summary

Quick Answer

Is a spin-off the same as selling the company?

Not exactly. A spin-off typically distributes ownership of a subsidiary to existing shareholders (or via a related transaction). Employees may receive new equity in the spun entity while keeping or adjusting parent awards—terms are deal-specific.

Quick Answer

Will my ISOs stay ISOs after a spin?

They can if the transaction is structured to satisfy substitution or assumption rules and ISO continuity tests. If awards are cashed out or modified unfavorably, ISO status may be lost. Read the equity adjustment appendix to the merger agreement.

Quick Answer

Where do RSU taxes hit?

Generally when shares deliver and income is fixed—often ordinary wage income. If vesting accelerates, you may recognize more income in the transaction year—model withholding.

Spin-offs sit between organic growth and M&A. Employees experience two tickers, new plan documents, and sometimes new employers within a controlled group.
