My Company Is Being Acquired. What Happens to My Stock Options?
Your options are typically either cashed out for the deal price minus your strike price, converted into equivalent options in the acquiring company, or canceled without payment.
An acquisition doesn’t have one standard outcome for employee stock options. It depends on how the specific deal is structured, what your company’s option plan says, and whether your options are vested or not. The three broad outcomes are a cash payout, a conversion into the acquiring company’s stock, or cancellation with no payout if your options are underwater. This post covers how to tell which applies to you, what accelerated vesting can change, and how the payout is typically taxed.
What actually happens to my options when my company gets acquired?
The acquiring company and your company negotiate specific treatment for outstanding options as part of the deal terms, and that treatment gets spelled out in the merger agreement. There’s no default outcome required by law. The three most common approaches are: cashing out vested options for the difference between the deal price and your strike price, converting your options into equivalent options or shares in the acquiring company (continuing on a similar vesting schedule), or canceling options entirely without payment if the deal price is at or below your strike price. Your company is required to notify option holders of the actual treatment before or at closing. Read that notice carefully, since it overrides any general expectations.
What happens to my vested options?
Vested options are most commonly cashed out at closing, paid as the deal’s per-share price minus your strike price, multiplied by your number of vested shares. Some deals instead convert vested options into shares or options of the acquiring company rather than paying cash, particularly in stock-for-stock mergers or when the acquirer is itself a private company. Either way, vested options almost always retain their value in some form in a normal acquisition. It’s unvested options where the outcome varies more.
What happens to my unvested options?
This depends entirely on whether your option plan includes an acceleration provision, and if so, what kind. Without any acceleration clause, unvested options are typically converted into a new unvested grant in the acquiring company, continuing on the same or a similar vesting schedule as before. You keep the potential value, but you have to keep working to earn it. Some plans include acceleration clauses that speed up vesting specifically because of the acquisition, which changes this outcome substantially (see below).
What is double-trigger acceleration, and does it apply to me?
Double-trigger acceleration is a provision that vests some or all of your unvested options automatically, but only if two separate events both occur: the acquisition itself, and then a qualifying termination of your employment, typically being let go without cause, or resigning for “good reason,” within a set window afterward, commonly 9 to 18 months post-closing. It’s the most common form of acceleration at venture-backed startups today, largely because acquirers want to retain the team they’re paying for, and a provision that vests everyone’s equity the moment the deal closes (called single-trigger acceleration) would undercut that. Check your grant agreement or option plan directly. Not every company includes this provision, and the specific window and percentage accelerated vary.
What if the deal price is below my strike price?
If the acquisition price per share is at or below your strike price, your options are “underwater,” there’s no spread left to pay out, so they’re typically canceled entirely with no compensation, since exercising them wouldn’t make financial sense for anyone. This can happen even at companies that raised money at much higher valuations previously, particularly in a down-round acquisition or a distressed sale, and it applies regardless of how long you’ve worked there or how close you were to fully vesting.
How are cashed-out options taxed?
For NSOs, a cash-out is generally taxed as ordinary income on the full spread between the deal price and your strike price, similar to a normal exercise-and-sale. For ISOs, cashing out generally counts as a disqualifying disposition unless you’d already independently met the one-year and two-year holding requirements before the deal closed, meaning the spread is typically taxed as ordinary income rather than getting long-term capital gains treatment. If your options are instead converted into acquirer equity rather than cashed out, the tax treatment depends heavily on how the deal is structured. This is genuinely complex territory, and it’s worth confirming the specifics with a tax professional once your company communicates the actual deal terms, rather than assuming any general rule applies.
Worked example
Say you have 8,000 vested NSOs with a $4 strike price, and the acquisition prices the company’s shares at $16 each in an all-cash deal.
Payout: 8,000 × ($16 − $4) = $96,000, before tax
Tax: taxed as ordinary income in the year of the deal, so at a 32% marginal rate, roughly $30,700 in tax, leaving about $65,300 net
It’s also common for part of the deal proceeds, including employee option payouts, to be held back in an escrow account for a period after closing, often 12 to 18 months, to cover potential claims against the sellers. If your deal includes an escrow holdback, you may not receive the full amount immediately at closing even for a straightforward cash deal, so it’s worth checking whether that applies to your specific payout.
FAQ
Do I automatically get paid out when my company is acquired? Only for vested options, and only if the deal structure calls for a cash payout rather than a conversion into acquirer equity. Check your company’s specific deal communications.
What happens to unvested options in an acquisition? It depends on your option plan. Without an acceleration clause, they typically convert into a new unvested grant on a similar schedule. With double-trigger acceleration, they can vest immediately if you’re let go without cause within a set window after the deal closes.
What if my options are underwater at the acquisition price? They’re typically canceled without payment, since there’s no financial benefit to exercising options priced above what the shares are actually worth in the deal.
Is single-trigger acceleration common? No. It’s relatively rare and generally disfavored by acquirers, since it can accelerate departures right after a deal closes. Double-trigger acceleration is far more standard.
How soon after the acquisition do I get paid? Timing varies by deal, and a portion of proceeds, including option payouts, is often held in escrow for 12 to 18 months, so you may not receive the full amount immediately at closing.
What to do next
The specific outcome for your options is determined by your merger agreement and option plan, which your company is required to communicate to you around the deal. That documentation is the source to rely on, not general patterns like the ones described here. You can model your own numbers at movewealth.io.
