What happens to your equity in an acquisition

When your startup gets acquired, your equity converts into one of three things: cash, stock in the buyer, or some mix of the two. What you actually receive is not the headline price divided by your ownership percentage. It is what is left after the preferred shareholders are paid first, after any unvested shares are handled, and after the deal's own terms decide whether you keep working there to collect it. Common stock, the kind employees hold, sits at the back of the line.

This post walks the payout waterfall in order, with worked numbers. If you are still deciding whether to take an offer in the first place, start with how to evaluate a startup job offer and is startup equity worth it in a down market. Here we assume the acquisition is already happening and you want to know what hits your account.

Cash deal, stock deal, or both?

The first fork is the form of payment, because it changes both your tax bill and your risk.

• All-cash. The buyer pays cash for your shares. Cleanest outcome: your vested shares convert to a dollar amount, you are taxed on the gain, and you are done. You no longer have equity in anything.
• All-stock. Your shares convert into the buyer's shares at an agreed exchange ratio. Common in acquirer-is-public deals (you get public stock you can usually sell) and acquirer-is-private deals (you get illiquid stock and a new, longer wait). Often structured to defer tax until you sell.
• Cash plus stock. The most common large-deal structure. Some money now, some upside (or risk) carried forward in the buyer's shares.

A cash deal pays you on the buyer's timeline. A stock deal makes you a shareholder in the acquirer, which means you are now betting on their stock, not your old one. If the buyer is private, you have effectively restarted the illiquidity clock that how startup equity makes money or not describes.

Who gets paid first: the liquidation preference

This is the single most important mechanic and the one most employees have never read. Investors buy preferred stock. You hold common stock. Preferred sits ahead of common in the payout order, and its liquidation preference says it gets paid back first before common sees a cent.

A 1x non-participating preference means an investor who put in $20,000,000 gets back the greater of (a) their $20,000,000 or (b) what their shares are worth if they convert to common. Most clean venture deals are 1x non-participating. The danger cases are higher multiples (2x, 3x) and participating preferred, which takes its money back and then shares in the rest alongside common. Participating preferred is the term that quietly eats employee outcomes in a mediocre exit.

What do common holders actually get? A worked example

Numbers make this concrete. Say a company sells for $60,000,000. It raised $40,000,000 across its rounds, all 1x non-participating preferred. Employees and founders hold common.

Now change one term. Make the same $40,000,000 participating 1x. Preferred takes its $40,000,000 back, then splits the remaining $20,000,000 pro rata with common. If preferred owns 60 percent of the company, it takes another $12,000,000, leaving $8,000,000 for common instead of $20,000,000. Your 0.40 percent slice falls from $80,000 to about $32,000 (illustrative, not advice). Same sale price, same ownership, less than half the payout, entirely because of one word in a term sheet you never signed.

The headline acquisition price tells you almost nothing about your check. The cap table's preference stack tells you almost everything.

And in a down-market sale where the price is near or below total money raised, common can get zero while investors are made whole. That is the structural reason a $200,000,000 exit can still pay employees nothing if the company raised $250,000,000 first. It is the same risk that is startup equity worth it in a down market covers from the joining side.

Does my equity accelerate when we get acquired?

Not automatically. Acceleration depends on what your option agreement says, and most employee grants say nothing, which means no acceleration. Two clauses matter:

• Single-trigger acceleration. Some or all of your unvested shares vest the moment the acquisition closes. Rare for rank-and-file, more common for founders and early executives.
• Double-trigger acceleration. Your unvested shares accelerate only if both the acquisition closes and you are terminated (or constructively let go) within a window, often 12 months. This is the more common protective term when it exists at all.

If you have neither, your unvested shares are typically assumed by the buyer and you keep vesting on the original schedule, now as the buyer's employee. This is why acquirers attach retention packages: new equity grants and cash bonuses that vest over 1 to 3 years to keep you from leaving. Sometimes that retention money is larger than your original equity payout. For how vesting cliffs and schedules work in the first place, see how stock options and vesting work.

What about my strike price and unexercised options?

If you hold options (not shares yet), the acquisition forces a decision. Vested options usually get cashed out at the deal price minus your strike. If the deal price per share is $4 and your strike is $1, you net $3 per share on vested options, before tax. If your strike is above the deal price, your options are underwater and worth nothing in this sale. Unvested options follow the acceleration rules above: assumed, accelerated, or cancelled depending on the agreement and the deal.

This is the moment the early decision to exercise or not comes due. The trade-offs (cost, AMT, the risk of buying shares that later go to zero) are the subject of what happens to options when you leave and how startup equity makes money or not. In an acquisition you do not get to undo that decision, you just collect on it.

What about escrow, earnouts, and holdbacks?

The full headline number rarely arrives at once. Two structures delay it:

• Escrow / holdback. A slice of the proceeds (often 10 to 15 percent) is held back for 12 to 24 months to cover any claims the buyer makes after closing. You get it later, if at all.
• Earnout. Part of the price is contingent on the acquired business hitting targets after the deal. Earnouts are where optimistic headline prices go to quietly shrink. Treat earnout dollars as maybe-money, not real money, until they land.

So a deal announced at $60,000,000 might be $45,000,000 at close, $9,000,000 in escrow released over two years, and $6,000,000 in earnout that may never fully pay. Your share follows the same shape.

The questions to ask before and during a deal

You usually cannot change the terms, but you can know what you are holding. Ask these, ideally before you ever join, and again if a deal is on the table:

1. 01What is the total preference stack? How much money has been raised, and at what preference multiple? This single number caps the common pool.
2. 02Is any of the preferred participating? Participating preferred is the term that most quietly shrinks employee outcomes.
3. 03Do my options have single or double-trigger acceleration? Read your own grant agreement. If it says nothing, assume none.
4. 04What is the form of payment? Cash, public stock, or private stock changes your tax and your liquidity.
5. 05How much is escrow, holdback, or earnout? Discount any contingent money heavily.
6. 06Is there a retention package, and what does it vest on? This is often the larger number for engineers who stay.

Most of these are the same questions worth asking before you accept any equity offer in the first place. The full pre-join list lives in startup equity: seed, Series A, B, what to ask and how to evaluate a startup job offer. An acquisition just turns those abstract terms into a real check or a real disappointment.
