Foundations & Regulation

01SPAC Special Purpose Acquisition Company

A SPAC is a publicly traded shell company formed to identify and combine with an operating business. It has no substantial operating business of its own before the transaction and provides an alternative route for a target company to enter the public markets.

02Sponsor

The sponsor is the person, group, or organization that forms and initially finances the SPAC, appoints its management, and leads the search for a target company. Sponsor compensation and economic incentives may differ from those of public shareholders and should be reviewed carefully.

03Target Company

The target company is the private operating business with which the SPAC proposes to complete a Business Combination. Its operations, financial statements, valuation, projections, risks, and management become central to the investment analysis.

04IPO Initial Public Offering

An IPO is the first public sale of a company’s securities. A SPAC conducts an IPO to raise capital before it has selected or completed a transaction with an operating target. The offering is described in a registration statement and prospectus.

05SEC Securities and Exchange Commission

The SEC is the U.S. federal securities regulator. It administers disclosure rules, reviews filings, enforces federal securities laws, and works to protect investors and maintain fair, orderly, and efficient markets. SPAC IPO and de-SPAC documents can be reviewed in the SEC’s EDGAR database.

06Trust or Escrow Account

Most SPAC IPO proceeds are generally held by a third party in a trust or escrow account until a Business Combination, redemption, extension-related payment, or liquidation. The governing documents describe permitted investments, withdrawals, taxes, expenses, and the calculation of each public share’s pro rata amount.

Illustrative examples

If a SPAC sells 20 million public units at $10.00 each and deposits that amount into trust, the initial trust balance would be approximately $200 million. If the later pro rata amount is $10.25 per public share, 100 eligible public shares would represent approximately $1,025 of trust value.

This simplified calculation does not account for taxes, permitted withdrawals, expenses, additional contributions, creditor claims, or other adjustments. The actual trust balance and per-share amount are stated or calculated under the applicable SPAC documents.

What investors may hold

Securities & Trading

07Units

Units are the securities commonly sold in a SPAC IPO. A unit typically contains one common share and a fraction of a warrant; some offerings instead include rights. The exact composition is stated in the prospectus.

Illustrative examples

Common IPO offering price: $10 per unit.

Warrant structure: 1 unit = 1 share + 1/4 warrant. Four units therefore contain four shares and, in total, one whole warrant.

Rights structure: 1 unit = 1 share + 1 right (10 rights = 1 share). Ten units therefore contain ten shares and ten rights. With an illustrative 10:1 conversion ratio, those rights may automatically convert into one additional share when the Business Combination closes.

These are common examples, not standard rules. The offering price and composition can differ. A unit may contain a different warrant fraction, a different rights ratio, multiple components, or neither a warrant nor a right.
08Warrants Including Warrant Redemption

A warrant gives its holder the right, but not the obligation, to purchase shares under specified price and time conditions. A SPAC or combined company may also redeem warrants when the warrant agreement’s conditions are met.

Illustrative examples

1 whole warrant may allow the purchase of 1 share for $11.50. It may become exercisable on the later of 30 days after the Business Combination or 12 months after the IPO and expire five years after the Business Combination. Earlier redemption or expiration may apply.

Terms vary significantly. Check the exercise price, ratio, start date, expiration date, cashless-exercise provisions, adjustments, and redemption triggers in the prospectus and warrant agreement.
09Rights

A right commonly converts automatically into a specified fraction of a share if the Business Combination closes. Unlike a warrant, it generally does not require payment of an exercise price.

Illustrative examples

10 rights = 1 share. If an investor holds 100 rights when the Business Combination closes, those rights may automatically convert into 10 shares of the combined company.

The conversion ratio can differ—for example, 1/5, 1/10, or another fraction—and the rights may expire without value if no Business Combination closes.
10Unit Split

After the initial trading period, units may become eligible to separate into their components. Shares, warrants, and any rights can then trade independently under their own symbols, subject to the offering terms and the required separation process.

Illustrative examples

Warrant structure: With 1 share + 1/4 warrant per unit, splitting 100 units produces 100 separately tradable shares and 25 whole warrants.

Rights structure: With 1 share + 1 right per unit, 100 units produce 100 shares and 100 rights. At a 10:1 conversion ratio, the rights could later become 10 shares if the merger closes.

Separation may not happen automatically. Broker procedures, timing, fees, component ratios, trading symbols, and treatment at the Business Combination vary by SPAC.

From the IPO to closing

Typical lifecycle of units, warrants, and rights

This simplified timeline shows when the securities commonly separate and what may happen at the Business Combination. It illustrates two alternative unit structures: a unit with a warrant and a unit with a right.

  1. 0%
    SPAC / IPOInvestors initially purchase a bundled unit, commonly for $10.00. Separate trading may become available later—frequently around the 52nd day, but sometimes earlier or later—and is independent of whether or when an LOI is announced.
  2. 25%
    LOIA preliminary, usually non-binding intent may be announced. If separate trading has already begun and the holder has separated the units, the shares and warrants or rights can trade independently. Some transactions skip an LOI.
  3. 50%
    Definitive AgreementThe binding transaction agreement is announced. Separated shares, warrants, and rights continue trading under their own symbols and can have different market prices.
  4. 75%
    Merger VoteEligible public shareholders generally receive a voting and/or redemption opportunity. Separately held warrants and rights usually remain outstanding under their own terms even if the shares are redeemed.
  5. 100%
    Merger / ClosingAny remaining units are commonly separated automatically. Eligible shares convert into shares of the combined company, rights generally convert automatically, and warrants generally continue and may become exercisable later.

Illustrative examples

Warrant structure

100 units → shares and warrants

At the IPO: 100 units at $10.00 cost $1,000 and contain 100 shares + 25 whole warrants when each unit includes one-quarter warrant.

After separate trading begins: the holder may request that the 100 units be separated. The resulting 100 shares and 25 whole warrants can then trade independently under their respective symbols. The required process may involve the holder’s broker and transfer agent.

At closing: the 100 shares generally become 100 shares of the combined company; the 25 warrants continue. A typical whole warrant may later permit the purchase of one share for $11.50 and may expire five years after closing.

Rights structure

100 units → shares and rights

At the IPO: 100 units at $10.00 cost $1,000 and contain 100 shares + 100 rights when each unit includes one right.

After separate trading begins: the holder may request that the 100 units be separated. The resulting 100 shares and 100 rights can then trade independently under their respective symbols. The required process may involve the holder’s broker and transfer agent.

At closing: with 10 rights = 1 share, the 100 rights automatically become 10 additional shares. Together with the 100 original shares, the investor then holds 110 shares, before other transaction adjustments.

Illustrative structures only. The percentages identify the displayed milestones and do not represent fixed timing, probability of success, valuation, or performance. The separation date is not universal, separation before closing may not be automatic, fractional warrants may be rounded down, and unit composition, prices, ratios, redemption rights, exercisability, adjustments, and closing treatment are governed by the specific prospectus and agreements. If no Business Combination closes, public shares may be redeemed or liquidated while warrants and rights commonly expire worthless.

From target search to completion

Transaction Stages & Investor Decisions

11LOI Letter of Intent

An LOI usually records preliminary, mostly non-binding terms for a possible transaction and can provide a framework for negotiations and due diligence. Not every transaction uses or publicly announces an LOI.

12Definitive Agreement

A definitive agreement is the legally binding contract governing the proposed Business Combination. It describes matters such as transaction structure, valuation, consideration, financing, closing conditions, termination rights, and regulatory requirements.

13Business Combination / De-SPAC

The Business Combination or de-SPAC transaction combines the SPAC with an operating target. If all approvals and closing conditions are satisfied, the target becomes part of a publicly traded operating company. A merger is a common structure, but other transaction structures are possible. Any units still outstanding at closing are commonly separated automatically into their underlying shares and warrants or rights.

Illustrative examples

Warrant structure: If 100 units each contain one share and one-quarter of a warrant, the unit separation produces 100 shares and 25 whole warrants. At closing, the shares generally convert into shares of the post-combination company, while the warrants generally continue as warrants for that company under their existing terms.

Rights structure: If 100 units each contain one share and one right, and 10 rights = 1 share, the unit separation produces 100 shares and 100 rights. The rights then convert automatically into 10 additional shares at closing, resulting in 110 shares before any other transaction adjustments.

Illustrative structures only. Unit contents, conversion ratios, fractional-security treatment, adjustments, timing, and post-closing warrant terms vary by SPAC and are governed by its prospectus, agreements, and transaction documents.
14Merger Vote or Tender Offer

Depending on the transaction structure, public shareholders may receive a proxy statement for a shareholder vote or a tender offer. These documents explain the target, transaction terms, sponsor interests, financing, dilution, voting procedure, redemption rights, and relevant deadlines.

Illustrative examples

A shareholder may be permitted to vote for the Business Combination and still redeem 100 public shares for their pro rata trust amount. Voting and redemption can therefore be separate decisions.

Eligibility, submission requirements, share-delivery instructions, deadlines, withdrawal rights, and the relationship between voting and redemption depend on the transaction documents. Missing a deadline may eliminate the redemption right.
15Extension

An extension gives the SPAC additional time to complete a Business Combination. It may require shareholder approval, an amendment to the governing documents, sponsor contributions to the trust account, and a new opportunity for eligible shareholders to redeem.

Illustrative examples

If the completion deadline is June 30, shareholders might approve an extension to September 30. Eligible holders may receive another opportunity to redeem, and the sponsor may be required to contribute a specified amount to the trust for the additional time.

Extension length, number of permitted extensions, voting threshold, trust contribution, redemption opportunity, and procedures vary by SPAC.
16Liquidation

If the SPAC does not complete a transaction within its permitted period and no extension applies, it generally winds up and liquidates. Eligible public shares are redeemed for their pro rata share of the remaining trust or escrow account. If public units are still outstanding, their share component is treated according to the liquidation and redemption mechanics in the offering documents; the warrant or right component generally receives no trust distribution and expires worthless.

Illustrative examples

An investor holds 100 public units, each containing one public share and one-quarter of a warrant. Economically, the investor has 100 public shares and 25 whole warrants. If the SPAC liquidates, the 100 public shares generally receive the applicable per-share amount from the trust account, while the 25 warrants expire worthless. In a rights structure, the public-share component would generally receive the trust distribution, while the rights would usually expire worthless rather than convert into shares.

This is not a fixed $0.0001 payment for warrants or rights. Liquidation amounts, unit-processing mechanics, eligibility, taxes, expenses, creditor claims, and the treatment of each security depend on the SPAC's governing documents and applicable law.

Capital, incentives, and ownership

Investor Economics

17Redemption

Eligible public shareholders can typically redeem their shares for a pro rata share of the amount held in the trust or escrow account. This amount may differ from both the original IPO price and the price paid on the open market. Procedures, deadlines, limitations, taxes, and permitted deductions are described in the applicable documents.

Illustrative examples

An investor buys 100 public shares at $12.00, paying $1,200. If the applicable redemption amount is $10.20 per share, redeeming those shares would return approximately $1,020, not the investor’s $1,200 purchase price.

The redemption amount is based on the applicable pro rata trust value, not the investor’s market purchase price. Eligibility, calculations, deadlines, required delivery, taxes, deductions, and treatment of separately held warrants or rights vary.
18Sponsor Promote / Founder Shares

The sponsor promote is the sponsor’s economic interest, often including founder shares acquired on terms different from those offered to public investors. It can reward the sponsor for completing a transaction, create conflicts of interest, and dilute public shareholders.

Illustrative examples

If public investors hold 8 million shares and the sponsor holds 2 million founder shares, the sponsor initially represents 20% of the 10 million shares in this simplified structure, before considering warrants, redemptions, financing, earnouts, or other issuances.

A 20% founder-share structure is only an illustration, not a universal rule. Sponsor economics may be restructured, forfeited, transferred, vested, or subject to other conditions, and the price paid by the sponsor may differ substantially from the public offering price.
19Dilution

Dilution reduces an investor’s percentage ownership or economic value per share when additional securities or compensation are issued. Potential sources include sponsor shares, warrants, rights, PIPE financing, transaction fees, earnouts, and other convertible or newly issued securities.

Illustrative examples

An investor owns 100,000 of 10 million shares, equal to 1.00%. If the company issues another 2 million shares and the investor receives none, the same 100,000 shares represent approximately 0.83% of 12 million shares.

This example shows percentage dilution only. Actual dilution analysis may also consider issue prices, warrants, rights, sponsor securities, redemptions, PIPEs, earnouts, fees, convertible securities, and changes in net tangible book value.
20PIPE Financing Private Investment in Public Equity

A PIPE is a privately negotiated investment in public-company securities, often arranged to help finance a de-SPAC transaction or replace cash lost through redemptions. PIPE investors may receive terms different from public shareholders, and the financing can contribute to dilution.

Illustrative examples

A PIPE investor agrees to purchase 5 million newly issued shares at $10.00 each. At closing, the transaction supplies approximately $50 million of additional gross capital, while the 5 million new shares increase the post-closing share count.

PIPE securities may have different prices, registration rights, lockups, preferred terms, warrants, conversion features, fees, or closing conditions. Gross proceeds are not the same as net proceeds.
