Equity in an acquisition

Merger agreements and plan documents decide what happens to your grant. The press release will not. Unvested awards can accelerate and cash out, turn into buyer equity, or get cancelled. Vested in-the-money options are often cashed out at (deal price per share − strike) × shares, subject to the waterfall.

Double-trigger acceleration — vest if acquired and you are terminated without cause (or quit for good reason) in a window — is the market norm for employee equity in venture-backed firms. Single-trigger (vest on change of control alone) is founder-friendly and buyer-unfriendly; many later-stage companies avoid it for the broad employee base.

The big idea

Your grant is a claim that the buyer can rewrite at the deal. Four common treatments:

Out-of-the-money options may be cancelled. Unexercised options can create a tax and timing scramble — see employee equity and equity taxes. Private-company RSUs often settle only on a liquidity event; an acquisition usually is that event, still subject to vesting and possible lockups if paid in buyer stock.

Walking through an employee read

When your company is acquired (or rumor says it will be):

1. Ask for the waterfall summary: purchase price, prefs outstanding, estimated proceeds per common share, escrow %.
2. Separate equity proceeds from retention / new-hire packages. Negotiate retention on its own merits.
3. Read treatment of unvested awards and any non-compete / non-solicit.
4. If paid in buyer stock, understand lockups, registration and concentration risk.
5. Do not make life decisions from the press-release number.

"We got acquired for $X" without waterfall context is not information. In an acquihire, old options often pay zero and the real money is the new package — see why buyers buy.

Common mistakes

• Assuming unvested shares vest on close. Many deals convert or cancel them.
• Mixing retention with the option cash-out. One is a new job offer; the other is the old cap table.
• Exercising underwater options because "there was an acquisition." Out-of-the-money can mean cancelled.

Check yourself

What is double-trigger acceleration?

Unvested equity accelerates only if there is a change of control and you are terminated without cause (or leave for good reason) in a window.

You hold unvested options in an acquihire whose equity waterfall is $0. Where might you still get paid?

A retention package — new cash or RSUs for staying — not the old grant.

Key takeaways

• Unvested treatment (assume, accelerate, cancel) is a first-class deal term.
• Double-trigger is the employee-market default; single-trigger is rarer for the broad base.
• In-the-money vested options cash out only after the waterfall.
• Read the merger agreement's employee and preference sections, not the blog post.
