How a SPAC deal gets valued, and why the headline number misleads

Every de-SPAC announcement carries a valuation, usually expressed as enterprise value and usually in the first line of the press release. It is a negotiated number, not a market-tested one, and understanding how it was built is most of the work.

Where the number comes from

Two parties agree it: the sponsor, who needs a deal, and the target, which wants the highest price it can defend. There is no bookbuild and no third party setting a clearing price. The S-4 discloses the basis, often a comparable-company analysis prepared by an adviser, and that disclosure is where the analysis should start rather than the press release.

The share count is the trap

A valuation of $1bn at $10.00 per share implies 100 million shares. In practice the pro-forma count includes rather more than the public float.

• Public shares, less whatever redeems.
• The sponsor's founder block, conventionally 20% of the post-IPO count.
• Shares issued to the target's existing holders, usually the largest slice.
• PIPE shares, often priced at $10.00 even when the market is below it.
• Warrants and rights, which arrive later but arrive.

The pro-forma table in the S-4 sets all of this out, generally under several redemption scenarios. Reading the no-redemption column alone is the single most common mistake, because it is the scenario least likely to occur.

Enterprise value against what cash

What to compute yourself

1. Take the pro-forma share count under a realistic redemption assumption, not the no-redemption case.
2. Multiply by $10.00 to get the implied equity value the deal is asking for.
3. Subtract the cash actually expected to arrive, trust after redemptions plus committed PIPE, to get the implied enterprise value.
4. Compare that against the comparables in the S-4, then against your own.

The result is frequently some distance from the headline. That gap is not evidence of bad faith; it is what happens when a number negotiated months earlier meets a redemption vote.
