What Are SPAC Sponsors and How Do They Get Paid?

A SPAC sponsor is the person or firm that forms a special purpose acquisition company, funds its startup costs, takes it public, and then hunts for a private business to merge with before a hard deadline runs out. Sponsors are paid primarily through “founder shares” — equity set at 25% of the IPO share count, bought for roughly $25,000 in total, which translates to about a 20% stake in the post-IPO company known as the “promote.” That stake only pays off if a merger actually closes, which is why sponsors face intense pressure to get a deal done and why their conflicts with public shareholders have become one of the most litigated and regulated areas of corporate law.

Who the Sponsor Actually Is

The sponsor is almost always a limited liability company formed specifically for the SPAC. Behind that LLC sit the people who really matter: private equity professionals, former investment bankers, or industry executives with a history of acquiring and growing companies. Offering documents sometimes refer to them as “sponsor persons.” They manage the sponsor entity, sit on or appoint the SPAC’s board, and run the search for a target.

Because a newly formed SPAC has no operating history, no revenue, and no assets outside its trust account, the sponsor’s reputation is effectively what IPO investors are buying. Institutional investors look at the sponsor team’s track record of closing mergers, their sector experience, and their ability to find undervalued businesses. A thin résumé makes raising capital hard. The blank-check structure only works when investors trust the people writing the check.

What Sponsors Do From IPO to Merger

The sponsor’s job starts well before the IPO. It forms the SPAC, files the registration statement, selects underwriters, and funds the offering costs out of its own pocket. Once the IPO closes and the proceeds go into trust, the real work begins: finding a private company worth taking public through a merger, known as the de-SPAC transaction.

That search involves heavy due diligence: reviewing financials, assessing growth potential, negotiating valuation, and structuring post-merger governance. The sponsor is responsible for preparing the proxy or registration statement that gives shareholders the information they need to vote on the deal or redeem their shares.¹

The Deadline

Sponsors work against a clock. Exchange listing rules generally require a SPAC to complete a business combination within 36 months of its registration statement becoming effective, though the SPAC’s own charter often imposes a shorter window.² Many SPACs set an initial deadline of 18 to 24 months, with extensions that typically require shareholder approval and an additional sponsor deposit into the trust account.¹ If time runs out without a signed deal, the SPAC dissolves, trust funds go back to public investors, and the sponsor loses everything it invested.

Lining Up PIPE Financing

Public shareholders can redeem their shares before a merger closes, and redemption rates have been very high in recent years. When most shareholders cash out, there may not be enough left in trust to meet the cash commitment the SPAC made to the target. Sponsors fill the gap with Private Investment in Public Equity (PIPE) financing — negotiating with institutional investors to put fresh capital in alongside the merger. To attract PIPE money, sponsors sometimes offer shares at a discount to market or sweeten the terms with convertible securities or extra warrants.

PIPE commitments also work as a credibility check. When sophisticated investors commit new money after seeing the specific target, the market can read that as a quality signal. A SPAC that cannot secure meaningful PIPE commitments is sending the opposite signal.

How Sponsors Get Paid

The sponsor’s main compensation is founder shares, bought before the IPO for a nominal price that typically totals around $25,000.³ Those shares are set at 25% of the IPO share count, giving the sponsor 20% of all outstanding shares after the offering.¹ That 20% is the promote, and it is the heart of the SPAC economic model.

When the merger closes, founder shares convert into common stock of the combined company. The arithmetic is what makes the promote controversial. A sponsor that paid $25,000 for shares later worth tens of millions has a cost basis so far below what public investors paid that it can still walk away rich even if the post-merger stock price drops well below $10 per share — the price point at which public shareholders are already losing money.

How the Promote Has Evolved

The flat 20% promote drew heavy criticism for misaligning sponsor and shareholder incentives, and deal structures have shifted in response. Sponsors increasingly forfeit a portion of their founder shares at closing to reduce dilution and improve economics for the target’s shareholders. Vesting and earnback provisions have become common, where some sponsor shares vest only if the post-merger stock price hits specified targets within five years or more. Some deals tie forfeiture to the amount of cash actually delivered at closing, pushing sponsors to maximize the capital available for the merger rather than close any deal at any cost.

Private Placement Warrants

Beyond founder shares, sponsors buy private placement warrants, typically with an exercise price of $11.50 per share, to help cover operating expenses and deferred underwriting fees.⁴ These warrants let the sponsor buy additional shares at that fixed price years after the merger, functioning as long-term upside tied to whether the combined company’s stock trades above $11.50. Unlike public warrants in the IPO units, private placement warrants are generally not transferable until after the de-SPAC transaction closes.

Lock-Up Periods

Sponsor shares are subject to lock-up agreements that bar immediate sales after the merger. Most sponsors face a one-year lock-up, though some agreements include early release provisions triggered by stock price appreciation above set thresholds.¹ Current SEC rules require SPACs to disclose the material terms of these lock-ups, including expiration dates, who is covered, and any early-release triggers.⁵

What Sponsors Risk

Sponsors front the money needed to launch and operate the SPAC before any merger happens. That at-risk capital covers legal fees, accounting work, regulatory filings, office costs, and the upfront portion of the underwriting commission. Underwriting fees typically run about 5% to 5.5% of the offering proceeds, with roughly 3% deferred until the de-SPAC closes.¹ The sponsor pays the upfront portion (around 2%) out of pocket or from private placement warrant proceeds.

None of that money is in the trust account. If the SPAC hits its deadline without closing a merger, the sponsor’s working capital, offering costs, and warrant investment are all gone. In larger SPACs, that can mean millions of dollars forfeited. This forfeiture risk is the standard justification offered for the size of the promote: the 20% stake pays the sponsor for carrying the risk that the venture produces nothing.

The Core Conflict With Public Shareholders

When a merger is announced, public shareholders choose between staying invested in the combined company and redeeming their shares for a pro rata share of the trust, typically about $10 per share plus accrued interest.⁶

High redemption rates create a cascading problem. As more investors redeem, fewer shares remain outstanding, but the sponsor’s 20% promote does not shrink. The sponsor’s founder shares dilute remaining shareholders more heavily as redemptions climb. In extreme cases, the SPAC becomes a near-empty shell where the sponsor owns a disproportionate slice of a company with little cash to operate.

Most de-SPAC merger agreements include a minimum cash condition, requiring a specified amount at closing from remaining trust funds plus PIPE proceeds.¹ If redemptions push the SPAC below that threshold and PIPE money cannot fill the gap, the deal collapses and the sponsor loses the promote, the warrants, and the at-risk capital. That is where the conflict is sharpest. The sponsor profits from virtually any completed deal, even a bad one, but loses everything if no deal closes.

Fiduciary Duties and the MultiPlan Standard

SPAC directors and officers owe the same fiduciary duties of loyalty and care as any corporate board. Under Delaware law, which governs most SPACs, the board must act in the best interests of the corporation and its shareholders when evaluating a merger.⁷

In ordinary deals, the business judgment rule shields board decisions from judicial second-guessing when directors have no conflicting personal interest, exercise reasonable care, and act in good faith.⁷ SPACs are not ordinary. The promote means the people steering the deal toward closure stand to gain enormously from any merger, even one that destroys value for public shareholders.

The 2022 Delaware Chancery Court decision in In re MultiPlan Corp. Stockholders Litigation applied entire fairness review, Delaware’s most demanding standard, to a de-SPAC merger. The court found that the sponsor’s founder shares created a disabling conflict and that the SPAC’s directors were also conflicted because they held founder shares and had been appointed by the sponsor. Under entire fairness, the burden shifts to the defendants to prove that both the price and the process of the transaction were fair to minority public shareholders. The court emphasized that SPAC fiduciaries must give shareholders all material information needed to make a fully informed decision about whether to redeem or stay invested. When disclosures are materially incomplete, shareholders cannot meaningfully exercise their redemption rights, and that failure of candor is itself a breach of duty.

The practical takeaway for any sponsor and board today is to assume the de-SPAC transaction will face entire fairness scrutiny if challenged, and to build procedural protections — independent board committees, arms-length negotiations, robust disclosure — into the deal from the start.

What Sponsors Must Disclose

In 2024 the SEC adopted comprehensive SPAC disclosure rules, codified in Regulation S-K Subpart 1600 and effective July 1, 2024.¹ The rules significantly expanded what sponsors must tell investors at the IPO and when proposing a merger.

Compensation and Dilution

SPACs must disclose, in tabular format on the cover page and in the prospectus summary, the nature and amount of all compensation paid to the sponsor, its affiliates, and any promoters. That includes cash, stock, warrants, and reimbursements payable upon completion of the merger. The disclosure must also describe how this compensation may cause material dilution of public shareholders’ equity.⁵ The same tabular disclosure must appear again in the de-SPAC proxy or registration statement, updated for the specific deal.

Conflicts of Interest

The rules require disclosure of any actual or potential material conflict between the sponsor and public shareholders, including conflicts arising from how the SPAC compensates the sponsor and its officers and directors. Any agreements between the sponsor and specific investors about redemption, along with the material terms of all lock-ups and side letters that could affect public shareholders’ rights, must also be disclosed.⁵

Target Company Co-Registrant

In a registered de-SPAC transaction, the target company must now sign on as a co-registrant on the registration statement. That subjects the target to liability under Section 11 of the Securities Act, the same strict standard that applies in a traditional IPO.¹ Before this rule, targets could reach public markets through a SPAC merger without the disclosure liability they would have borne in a conventional IPO.

No More PSLRA Safe Harbor

The SEC also closed a widely used loophole on forward-looking statements. By amending the definition of “blank check company” in Securities Act Rule 405 to cover SPACs, the Commission made the Private Securities Litigation Reform Act’s safe harbor for forward-looking statements unavailable in de-SPAC transactions.⁸ During the SPAC boom, sponsors and targets routinely shared aggressive revenue and earnings projections during the de-SPAC process and relied on the safe harbor to shield them from liability if the projections fell short. That protection is gone. Sponsors and targets now face the same litigation risk for projections that any company faces in a traditional IPO.

Taxation of the Promote

How founder shares are taxed is an area of real uncertainty, and the dollars at stake are large. The core question is whether the spread between what the sponsor paid for founder shares and their fair market value is taxed as ordinary compensation income or as capital gain at lower rates.

Under Section 83 of the Internal Revenue Code, when property is transferred in connection with the performance of services, the recipient is taxed on the difference between fair market value and what they paid.⁹ Timing depends on whether the shares are subject to a substantial risk of forfeiture. Founder shares typically are, since they become worthless without a completed merger, so the tax event is deferred until the shares vest and is measured at the later fair market value.

Sponsors can avoid that deferred-taxation trap by filing a Section 83(b) election with the IRS within 30 days of receiving the shares.⁹ The election has the IRS tax the shares based on their fair market value at the grant date, which can be close to zero if the SPAC has just been formed and holds no assets. All later appreciation is then taxed as capital gain rather than ordinary compensation income, potentially cutting the rate nearly in half.

The 30-day deadline is absolute. Miss it and the election cannot be made retroactively, and the sponsor will be taxed at ordinary income rates on the full spread when the shares vest, which after a successful merger can be millions of dollars. The analysis is also fact-dependent: sponsors whose founder shares are not issued until close to the IPO, when the SPAC has a clearer market value, face a less favorable calculation. Getting the timing and the election right calls for tax advice early in the formation process.
