SPAC Transactions

Step 1: Founder Share Ownership Percentage

Founder Ownership % = Founder Shares / (Founder Shares + Public Shares)

Founder Ownership % = 7.5m / (7.5m + 30.0m) = 7.5m / 37.5m = 20.0% (0.20)

This 20% figure is the standard "promote" — nearly every SPAC sponsor negotiates founder shares equal to 20% of the post-IPO share count, regardless of deal size or sector. It's a fixed feature of the structure, not something typically renegotiated case by case.

Step 2: Value of the Sponsor Promote at Closing

Promote Value = Founder Shares × Reference Share Price

Promote Value = 7.5m × $10.00 = $75.0m

This is what the sponsor's founder shares are worth at closing, assuming the stock trades at the $10.00 reference price. Because the promote is a fixed share count rather than a return tied to invested capital, its dollar value barely depends on how good or bad the underlying deal turns out to be — as long as a deal closes at all.

Step 3: Trust Cash Remaining After Redemptions

Remaining Trust Cash = Trust Account × (1 − Redemption %)

Remaining Trust Cash = $300.0m × (1 − 0.50) = $300.0m × 0.50 = $150.0m

Redemptions matter because every public shareholder can pull their pro-rata share of trust cash out before the vote and keep their warrants for free. High redemption rates shrink the cash actually available to fund the deal, which is why sponsors often need a backstop — a PIPE or forward purchase agreement — to get the transaction closed.

Step 4: Sponsor's Return Multiple and the Conflict of Interest

Sponsor Return Multiple = Promote Value / At-Risk Capital

Using the promote value of $75.0m and the sponsor's at-risk capital of $8.5m:

Sponsor Return Multiple = $75.0m / $8.5m = 8.8x

This is the core conflict of interest in the SPAC structure: the sponsor turns $8.5m of at-risk capital into roughly $75.0m of stock — an 8.8x return — simply by getting a deal done, independent of whether that deal creates value for public shareholders. Because the sponsor loses its entire stake if no deal closes in time, the incentive is to close a deal before the deadline, not necessarily the best deal. Public shareholders, by contrast, can redeem for cash and walk away with no downside, which is why redemption rates spike whenever the market senses a weak target.

Final Results

• Founder Ownership: 20.0% (0.20)
• Sponsor Promote Value at Closing: $75.0m
• Remaining Trust Cash After Redemptions: $150.0m
• Sponsor Return Multiple on At-Risk Capital: 8.8x

These figures are what an interviewer is really testing when they ask about SPACs: not just the mechanics of trust accounts and warrants, but whether you understand that the sponsor's payoff is structurally asymmetric to the deal's actual quality.
