📖 SPAC Glossary

18 terms explained in plain English. No Wall Street jargon.

The SPAC world is full of euphemisms designed to make bad deals sound sophisticated. Here's what everything actually means.

SPAC

Also known as: Special Purpose Acquisition Company

A shell company that raises money through an IPO with the sole purpose of acquiring a private company within 18-24 months. Also called a 'blank check company.' The SPAC has no operations — it's just a pile of cash looking for a deal.

Blank Check Company

Another name for a SPAC. Called 'blank check' because investors give their money without knowing what company will be acquired. SEC classifies SPACs under SIC code 6770.

Promote

Also known as: Founder Shares, Sponsor Promote

The 20% equity stake that SPAC sponsors receive for organizing the deal. They pay ~$25,000 for shares worth millions. This creates a massive incentive to close any deal, even a bad one, because the sponsor profits regardless of post-merger performance.

Trust Account

Also known as: Escrow

When a SPAC IPOs, investor money goes into a trust account (usually invested in Treasury bills). The money stays in trust until either a merger closes or the SPAC liquidates. Investors can redeem their shares for ~$10/share from the trust before any deal closes.

De-SPAC

Also known as: De-SPAC Transaction, Reverse Merger

The process of a SPAC merging with its target company, taking the target public. After the de-SPAC, the combined entity trades under a new ticker. This is when retail investors are most at risk — the $10 floor disappears and the stock can drop to any price.

Redemption

Also known as: Share Redemption

Before a SPAC merger closes, investors can 'redeem' their shares and get ~$10 back from the trust. Hedge funds routinely redeem at 90%+ rates, keeping the profit from warrants while returning their principal. By 2023, redemption rates hit 95%, leaving SPACs with almost no cash to operate.

PIPE

Also known as: Private Investment in Public Equity

Additional capital raised from institutional investors at the time of the de-SPAC merger, usually at $10/share. PIPE investors often got crushed because their shares were locked up while the stock price collapsed. Over $100B in PIPE commitments were made during the boom.

Warrants

Also known as: SPAC Warrants

Options to buy shares at $11.50 that come bundled with SPAC units. They were marketed as a 'sweetener' for investors. In reality, warrants are dilutive — they create more shares, lowering the value for everyone. Most SPAC warrants expired worthless.

Reverse Stock Split

Also known as: Reverse Split

When a company combines shares to artificially raise the stock price (e.g., 1-for-10 turns 10 shares at $0.50 into 1 share at $5.00). SPACs use reverse splits to avoid being delisted for trading below $1. The record: Mullen Automotive did a 1-for-90,000 reverse split.

Zombie SPAC

A post-merger SPAC that's still technically listed but barely alive — trading under $2, burning cash, with no viable path to profitability. They haven't filed bankruptcy yet but almost certainly will. There are dozens of zombie SPACs still stumbling through the market.

Dilution

Also known as: Shareholder Dilution

The reduction in existing shareholders' ownership percentage when new shares are created. SPACs are dilution machines: sponsor promotes (20%), warrants, PIPE shares, earnout shares, and convertible notes all create new shares. A $10 SPAC share is typically worth $6-7 in real economic value after all dilution.

S-1 Filing

Also known as: Registration Statement

The SEC filing a SPAC submits to register its IPO. Contains details about the sponsor, trust size, underwriter, and terms. SPACs file under SIC 6770 (Blank Checks).

DEFM14A

Also known as: Proxy Statement

The filing sent to SPAC shareholders before a merger vote. Contains the target company details, financial projections, and merger terms. This is where the wildly optimistic revenue projections live — the ones that rarely come true.

Earnout Shares

Also known as: Earn-out, Performance Shares

Additional shares that vest if the stock hits certain price targets after the merger. Presented as 'aligned incentives' but often structured to vest quickly on short-term price spikes rather than long-term value creation.

Going-Concern Warning

An auditor's warning that a company may not survive the next 12 months. 44% of de-SPACed companies received going-concern warnings, compared to 22% of traditional IPOs. A red flag that often precedes bankruptcy.

D&O Insurance

Also known as: Directors & Officers Liability Insurance

Insurance protecting SPAC directors and officers from lawsuits. D&O premiums for SPACs skyrocketed 10x during the boom as insurers realized the lawsuit risk. An estimated $3.5B was spent on SPAC D&O insurance — money that came from investor capital.

Arbitrage

Also known as: SPAC Arbitrage

The risk-free strategy of buying SPAC shares near $10, holding for the trust floor protection, and redeeming before any risky merger. Hedge funds made an estimated $50B+ from SPAC arbitrage. The irony: the smartest SPAC strategy was to never own one post-merger.
