If there are rumours about an acquisition at your company, your coworkers and managers might all have different opinions about what that could mean.
You might be trying to work out:
What happens to your vested and unvested stock options
Whether you need to exercise your stock options before the deal closes
How much exercising could cost once taxes are included (spoiler: it can be a lot!)
And if you've already left the company, the pressure to make a decision about your stock options can be even higher. Your post-termination exercise window may already be counting down; it's often 90 days or less.
The tricky part is there's no single outcome when a startup gets acquired. The terms of the deal and your type of equity can affect what happens to your stock options. That means two employees, even at the same company, could end up with very different outcomes.
This article covers what you should know, including:
What happens when a startup gets acquired?
What to do with your stock options, step by step
How Secfi can help you plan for what happens if your startup gets acquired
How a startup acquisition changed the way Austin planned his equity and minimized his taxes
Note: If you're wondering what happens when your startup gets acquired, you can model potential outcomes with Secfi's free equity assistant Maeve.
When a startup gets acquired, what happens to your equity depends on the terms negotiated between your company and the buyer. There isn't one standard outcome.
Your vested and unvested options could be treated differently. The outcome also depends on whether you've already exercised your options, and whether you still work for the company.
Here are some of the ways an acquisition could affect employee equity:
| Possible outcome | What it could mean for you |
|---|---|
Your vested options are cashed out | The acquiring company may pay cash for your vested options as part of the deal. |
You receive shares in the acquiring company | Your existing equity may be exchanged for shares or options in the company buying your startup. |
You receive a mix of cash and stock | Some acquisitions use a combination of cash and equity, so part of your payout may be immediate while another part remains invested. |
Your unvested options are converted | Unvested options may be replaced with options or other equity in the acquiring company, potentially continuing on a vesting schedule. |
Vesting accelerates | Some acquisition agreements allow part or all of your unvested equity to vest sooner. This depends on your equity agreements and the terms of the transaction. |
Options are cashed out through a cashless exercise | In some deals, vested options can be exercised and sold as part of the acquisition in a cashless exercise, so you don't need to provide the exercise cost upfront. |
The price paid for the company matters too. If a startup is acquired for less than expected, investors with preferred shares may have the right to receive their money before common shareholders, including employees. In some cases, that can leave you with a much smaller payout than the headline acquisition price might suggest.
If your startup is being acquired, there are a few things to figure out as soon as possible:
What is your deadline to exercise your stock options?
Is there a stock option exercise blackout period?
How much will it cost to exercise? Include both the strike price and potential taxes such as ordinary income tax or AMT
What are the terms of the acquisition? Is it an all-cash deal, a stock-for-stock transaction, or a mix of cash and stock?
Your company may introduce a stock option exercise blackout period before the acquisition closes. During that period, you may be unable to exercise, buy, or sell stock options or shares. That can affect how much time you actually have to make a decision. Even if the acquisition itself is still weeks or months away, the practical deadline to exercise could come sooner.
Many startup employees have around 90 days to exercise vested stock options after leaving, although your actual deadline depends on your stock option agreement. If an acquisition happens during that window, compare your exercise deadline with the expected deal timeline, and find out how former employees' vested options will be treated.
In both cases, check your stock plan, grant agreement, and any acquisition-related communications you've received. You can also ask your company or stock administrator how these events could impact your particular grants before making a decision.
Before exercising your stock options ahead of an acquisition, calculate two things: what it will cost to buy the shares, and what taxes the exercise could trigger.
For incentive stock options (ISOs), exercising can increase your alternative minimum taxable income and potentially trigger AMT. For non-qualified stock options (NSOs), the difference between your strike price and the fair market value at exercise is generally treated as ordinary income.
Let's use a simple example to illustrate, but make sure you always check with a professional for your own situation.
Say you have:
5,000 vested ISOs
A $1 strike price
A current 409A valuation of $5 per share
Exercising all 5,000 options would cost $5,000 upfront:
5,000 options × $1 strike price = $5,000
At the current 409A fair market value, those shares have a paper value of $25,000. The difference between the $5,000 exercise cost and the $25,000 fair market value is a $20,000 bargain element, which may be included when calculating AMT.
That doesn't mean you'll automatically owe AMT on the full $20,000. Your actual tax bill depends on factors such as your income, filing status, state, other deductions and adjustments, and how many options you exercise.
This is where scenario planning can help. At Secfi, we help startup employees plan and finance their equity. We designed Maeve to make decisions like these easier, using the flexibility of AI with the reliability of our equity-specific tax calculators. Input your grant and tax details to estimate exercise costs and compare different scenarios, like upcoming acquisitions and optimizing for taxes.

Remember that an acquisition announcement doesn't guarantee the deal will close. If you exercise before closing, you're committing real cash to private company shares, so it's worth comparing the potential upside with the cost and risk before making a decision.
If you want to exercise before the acquisition closes but the upfront cost is more than you want or can afford to pay from savings, non-recourse financing may be an option.
Non-recourse financing can help cover the cost of exercising your stock options and associated taxes without putting your other personal assets at risk. With Secfi, repayment is generally tied to a successful liquidity event, such as an acquisition or IPO, according to the terms of your agreement.
There are no monthly payments like with a traditional bank loan, and your debt-to-income ratio is usually unaffected. That means it likely won't impact your ability to take out other types of financing like a mortgage in the future.

Once you know your deadline and estimated exercise cost, you can compare your options.
You may decide to exercise all of your vested stock options before the acquisition closes if you're comfortable with the upfront cost and potential risk.
But exercising everything isn't your only choice.
If your deadline allows, you could wait for more information about the acquisition. You could also exercise only part of your grant, based on how much cash you're comfortable committing, or use non-recourse financing for part of the exercise. Because an announced acquisition isn't guaranteed to close, it can help to model several scenarios before committing any cash.
Secfi provides equity planning support and non-recourse financing for startup employees and executives. We've helped over 55,000 startup employees and executives with equity planning, whether as individuals or with company-wide equity education provided by leadership teams.
Here's why employees from companies including Stripe, DoorDash, and Reddit work with Secfi to better understand and act on their equity.
An acquisition can leave you comparing several moving pieces at once: your exercise cost, potential taxes, deadlines, and what your equity could be worth under different outcomes. As we mentioned earlier, our AI equity assistant Maeve can help you organize your grant details and model different scenarios based on your own equity.
You can connect your Carta account directly or upload your grant documents, and Maeve can automatically extract the relevant equity details so you're set up quickly. It also shows the data and calculations behind its answers, letting you double-check any assumptions or outputs.

If you decide exercising makes sense, but the cost is too high to cover comfortably from savings, Secfi offers non-recourse financing for eligible employees.
The financing can help cover your exercise cost and associated taxes while allowing you to retain ownership of your shares. Your unrelated personal assets aren't used as collateral, and repayment is generally tied to a future liquidity event according to the terms of your agreement.
As of July 2026, we've provided over $800 million in non-recourse financing to startup employees, more than any other company in this space.
There's no minimum on the amount you can finance, and you can also combine non-recourse financing with your own cash rather than treating the decision as all-or-nothing.
If financing isn't the right fit, Secfi can also support you with a secondary sale if your company allows it and there's a market for your shares.
A startup acquisition can create decisions that go well beyond whether to exercise your options.
Secfi Wealth's financial advisors have daily experience in equity compensation and can help you consider your private-company equity alongside taxes, investments, diversification, major purchases, and other long-term financial goals.
Our financial advisors have a fiduciary duty to act in your best interests, and can provide support whether or not you choose to use non-recourse financing or exercise your options.
Here's what Austin, a sales director at a cybersecurity unicorn, said about working with our team:
"The value I'm getting is the tax planning, and the holistic approach. It's like all these things that I felt like were missing from a traditional financial advisor."
Here's more about Austin's experience:
Austin learned firsthand how quickly an acquisition can turn startup equity into a real financial decision.
At one of his first tech companies, the business was acquired suddenly. His vested options were automatically converted to cash, and on paper, it looked like he'd made hundreds of thousands of dollars.
But once he looked at the amount he received after taxes, he realized the outcome was very different from the headline figure. Looking back, he wished he'd planned better.
That experience changed how he approached equity at his next startup. Instead of waiting for another exit event to force a decision, he wanted to be more intentional.
"I remember telling my wife that I feel like I'm wading into new waters here. It's like, if we get this wrong, it could either cost us a ton in taxes now or thousands of dollars down the road."
When he found our team at Secfi, they helped him model different scenarios and gave him specific advice based on his situation, including planning his kids' education and his retirement.

What happens when a startup gets acquired depends on your equity, the deal terms, and your deadlines. The earlier you understand those pieces, the more room you have to compare your options before making a financial decision.
You can try Maeve to model different scenarios using your own equity details, or get in touch with our team if you want help understanding your options.
What happens to your stock options in an acquisition depends on the terms of the deal and your company's stock plan. Your options may be cashed out, converted into new shares or equity in the acquiring company, accelerated, or handled another way.
The outcome can also differ depending on whether your options are vested or unvested and whether you've already exercised. Startup exits can move quickly once an acquisition is announced, but the deal may still need to go through due diligence and other closing conditions before it becomes final.
If an acquisition is approaching, review your grant documents and model the potential financial and tax implications before making any decisions. Secfi's AI equity assistant, Maeve, can help you organize your grant details and compare different scenarios.
Unvested stock options don't automatically vest when your company is acquired. Depending on the acquisition agreement, they may continue vesting under the acquiring company, be converted into a new equity award, accelerate partially or fully, or be canceled.
Whether vesting accelerates may also depend on whether your grant includes single-trigger or double-trigger acceleration. Single-trigger provisions can accelerate vesting following the acquisition itself, while double-trigger provisions generally require the acquisition plus another event, such as losing your job under qualifying circumstances.
Your stock plan, grant agreement, and in some cases your employment contract ultimately determine what happens. If you're unsure, check the documents provided by your employer before assuming your unvested options will pay out. Secfi's Wealth team can also support you when evaluating an acquisition or other liquidity event.
Not necessarily. Whether you need or want to exercise before an acquisition depends on the deal terms, your exercise deadline, option type, exercise cost, and potential taxes.
Exercising before the deal closes may make sense in some situations, but it can also mean putting significant cash at risk. Depending on the option type and how long you hold the resulting shares, exercising earlier may also affect whether future gains could qualify for capital gains tax treatment.
You may decide to exercise everything, exercise only part of your grant, or wait if your deadline allows. Maeve can help you estimate exercise costs and taxes and compare different timing scenarios before you decide.
If your startup is acquired after you leave, what happens depends heavily on whether you exercised your vested stock options before your post-termination exercise period expired.
If you exercised, you generally own common stock and may participate in the acquisition according to the terms of the deal. If you didn't exercise before your deadline and the options expired, you may no longer have equity to participate with.
Post-termination exercise periods vary by company and grant, so check your option agreement rather than assuming you have a standard 90-day window. You can also use Secfi's AI equity assistant Maeve to model different scenarios using the information you have available.
When a company is acquired, the proceeds are distributed according to its capital structure and the terms of the transaction. Investors holding preferred stock may have liquidation preferences that give them the right to receive some or all of their investment before employees and other common stock holders are paid.
The full acquisition price may not necessarily be distributed at closing either. Some transactions include a holdback, where part of the purchase price is temporarily withheld to cover potential claims or other obligations, or an earn-out, where additional payments depend on the company meeting agreed targets after the acquisition.
That means the headline acquisition price doesn't necessarily tell you how much employees will receive. Your final payout can depend on investor preferences, the cap table, the acquisition price, your type of equity, and the specific deal terms. It's a complicated process that is quite detailed, so we recommend doing the appropriate research or talking to an advisor to better understand your situation.
