What is an all-stock acquisition, and what does it mean for founders?

An all-stock acquisition is when the buyer pays for your company entirely in their own equity rather than cash. Instead of receiving a wire transfer at close, you receive shares in the acquiring company. The headline deal value is real on paper. Whether you actually see that money depends on factors most founders don't fully understand until it's too late.

The Cursor deal is the clearest recent example. Anysphere (Cursor) sold for approximately $60 billion. Roughly 90% of the consideration was SpaceX stock. Founders and investors received SpaceX shares, not dollars. SpaceX is not public. There is no liquid market for those shares. To convert them into actual money, founders must find a buyer in the secondary market, participate in a company-run tender offer, or wait for an IPO that may never come.

The three core risks in all-stock deals

Lock-up risk. Stock consideration almost always comes with a lock-up period, typically 6 to 24 months post-close. During that window, you cannot sell. If the acquirer's stock drops 40% before your lock-up expires, your $60 million deal is now worth $36 million. You have no recourse.

Liquidity risk. Public acquirers offer the highest liquidity, but even public stock can gap down on earnings, macro shocks, or sector rotation. Private acquirers are worse. If the acquirer is not yet public and has no active secondary market, your stock is worth its appraised value on paper and zero in practice until a liquidity event occurs.

Concentration risk. You have swapped a diversified outcome (cash you can allocate across assets) for a concentrated position in a single company. If that company stumbles, your entire exit is impaired.

How to evaluate stock consideration before signing

Ask these questions before you accept any all-stock offer:

What is the acquirer's current valuation, and how was it derived? Public comps are easy to check. Private acquirer valuations are internal. A $10 billion private company with a 2022 VC round as its last mark may be trading at a deep discount in the secondary market today.

What is the lock-up structure? Standard is 12 months with quarterly vesting after that. Negotiate for a shorter lock-up, especially if the acquirer's stock is volatile or illiquid.

Is there a collar? A collar sets a floor and ceiling on the stock price used to calculate how many shares you receive. Without a collar, deal value can erode significantly if the acquirer's stock falls between signing and closing.

What are the tax implications? All-stock acquisitions structured as reorganizations can qualify for tax deferral, meaning you don't pay capital gains until you actually sell the shares. But this depends on structure and jurisdiction. Get a tax advisor involved before you agree to terms.

Is there any cash component? A mixed deal with 70% stock and 30% cash is meaningfully better than a pure stock deal. The cash component gives you immediate liquidity and de-risks the rest.

When an all-stock deal actually makes sense

All-stock deals are not inherently bad. They can be excellent in specific circumstances.

If the acquirer is a high-growth public company in a strong macro environment, their stock may outperform cash over the lock-up period. Founders who received Salesforce or Stripe stock as consideration in strategic acquisitions have done exceptionally well.

If you believe strongly in the acquirer's trajectory, holding their stock is essentially a reinvestment into a company you've already evaluated. You're betting on their continued growth.

If the deal structure offers favorable tax treatment and you have no immediate liquidity need, deferring gains while holding appreciating stock is a legitimate strategy.

What Thunder looks for in all-stock offers

When Thunder advises founders on all-stock consideration, we focus on four things: the acquirer's secondary market liquidity, the collar structure, the lock-up terms, and whether there's a cash backstop for at least founder personal needs post-close.

A $100M all-stock deal from a strong strategic acquirer with no collar and an 18-month lock-up is not the same as a $70M cash deal. The math depends on what actually happens to the stock. Make sure you're modeling the downside, not just the headline.
