Strike Price

Category: Equity Comp & Exits · Level: Advanced · Also called: Exercise price, Option price

TL;DR

The fixed price at which an option holder can purchase a share, set at fair market value on the grant date and locked in for the option's life.

The strike price is what the option holder pays per share to exercise their option. It's set at the fair market value of common stock on the grant date (per the most recent 409A valuation). When the company's value rises, the option becomes 'in the money' — the spread between current FMV and strike is the option's intrinsic value.

For early employees, low strike prices can mean significant value at exit. For late-stage employees joining at higher 409A valuations, strike prices are higher and the leverage from any further share-price appreciation is smaller.

Worked example

A January 2024 grant has $1.10 strike (per the December 2023 409A). Six months later the next 409A returns $4.20 — new grants issued in July use $4.20 strike. The earlier-grant employees gained $3.10/share of intrinsic value relative to new hires.

Common pitfalls

  • Setting the strike below FMV and triggering Section 409A penalties.
  • Failing to refresh the 409A before granting options at a stale strike.
  • Letting employees exercise large grants without understanding the cash and tax implications.
