SPAC Accounting

A special-purpose acquisition company (SPAC) is a shell firm that raises capital through a public offering of ordinary shares and warrants, then searches for a private operating company to acquire and take public. SPAC accounting is unusual because the company’s own shareholders own assets held in trust, creating a mismatch between traditional equity treatment and the economic reality that those shares can be redeemed for cash at the merger date.

The SPAC structure creates accounting complexity

When a SPAC raises capital in an initial public offering, it typically issues unit securities—each unit contains one ordinary share and a fraction of a warrant. The ordinary shares and cash proceed are segregated: most of the cash is placed in a trust account (the “trust” or “IPO trust”), accessible only if shareholders vote to approve a merger or if the SPAC is liquidated. If a merger is rejected by shareholders, they can demand redemption of their shares for a pro-rata portion of the trust account.

This redemption feature creates an accounting headache. Under traditional equity classification, share capital is permanent—issued, held, and retired only under extraordinary circumstances. A SPAC’s public shareholders, however, have a unilateral right to redeem their shares if they dislike the proposed acquisition. That right makes the shares contingent on a future event (the merger decision) and undermines the permanence assumption.

The consequence: the financial statements of a pre-merger SPAC classify public shareholders’ shares as temporary equity (also called redeemable temporary equity), sitting between liabilities and permanent shareholders’ equity. Sponsor founders, who have different (usually non-redeemable) shares, retain true equity classification. This split classification is one of the most distinctive features of SPAC accounting.

Trust shares live in a separate classification

ASC 480 and ASC 815 govern the treatment. Public shareholders’ shares are remeasured each reporting period to the redemption amount: the pro-rata value of cash in the trust divided by the number of redeemable shares outstanding. For a SPAC holding $100 million in trust with 10 million public shares, each share is valued at $10 per share (plus accrued interest on the trust account). When quarterly interest accrues, the liability adjusts upward. If some shareholders redeem early (possible between certain dates), the per-share value of the remaining redeemable shares increases.

This remeasurement creates a non-cash expense or income item on the income statement every quarter. If trust interest accrues, public shareholders’ temporary equity is credited (and a corresponding expense is recorded), because the redemption amount they could claim has risen. The effect is often immaterial in the early stages of the SPAC’s search but becomes material as the merger date approaches and redemption uncertainty crystallises.

Warrant liabilities must be fair-valued

Warrants are derivative instruments and are classified as liabilities under ASC 815. Each reporting period, the warrant liability is remeasured to current fair value using an option-pricing model (Black-Scholes or similar). The change in warrant value—sometimes dramatic—flows through the income statement as a gain or loss. If warrant prices surge (because the SPAC is approaching a popular acquisition), the warrant liability increases and a loss is recorded. Conversely, if the SPAC is perceived as risky, warrant fair value may fall and a gain is recognised.

This volatility can dominate pre-merger SPAC financial statements. A company with stable operations might report warrant losses that dwarf operating performance. Investors and analysts must be careful not to confuse fair-value swings in derivatives with core business results.

Redemptions just before the merger drive recapitalisation

As the merger vote approaches, public shareholders decide whether to support the transaction. Those who do not approve can redeem their shares for trust proceeds, roughly $10 per share (plus a small amount of accrued interest). If redemptions are significant—say 60% of public shares are redeemed—the SPAC’s balance sheet shrinks dramatically. The trust account depletes, temporary equity disappears, and the merged entity begins with a smaller cash pool and sponsor shares as the sole permanent equity base.

The accountant must recalculate all per-share metrics after the redemption lock-out period closes, because the capital structure has shifted. Diluted earnings per share, for example, depends on the share count at the merger close; if half the shares have been redeemed, dilution calculations change.

Sponsor shares are permanent equity despite their origin

The founders and early investors in a SPAC hold “founder shares” or “sponsor shares,” usually representing 20% of the fully diluted post-IPO share count. These shares carry no redemption rights (or heavily restricted redemption rights, with penalties). They are classified as permanent equity from inception and do not remeasure like public shares. However, sponsor shares often have acceleration or anti-dilution provisions, and they may carry supervoting rights. The accounting for these features is layered on top of the permanent equity classification.

A common structure: sponsor shares vest or vest faster if the merger closes within a certain time window, creating an incentive for sponsors to close a deal. Some SPAC charters lock sponsor shares for a period after the merger, preventing sponsors from selling immediately. These economic terms are interesting to investors but do not change the accounting classification as permanent equity.

The de-SPAC merger itself creates a fresh accounting baseline

When the SPAC votes to merge with an operating company, the acquired company becomes consolidated into the SPAC’s balance sheet, and the temporary equity classification ends. The merged entity’s balance sheet reflects the true capital contribution: cash contributed by public shareholders that was not redeemed, plus sponsor equity, less transaction costs and any earnout or contingent consideration payable to the acquired company’s sellers.

This is where accounting can surprise shareholders. If 70% of public shareholders redeemed, the merged entity inherits only 30% of the IPO cash raised. The effective cash proceeds are far smaller than the IPO headline amount. Earnout obligations owed to the acquired company’s founders add another layer of contingent claims on future profits. The merged entity’s balance sheet may look thinner than expected.

Earnouts and contingent consideration follow standard merger accounting

Once the merger closes, any contingent payments to the acquired company’s shareholders—earnouts based on hitting revenue or EBITDA targets—are recognised as a liability and re-measured through fair value under ASC 820. This is no different from any other acquisition, but the cash drain from redemptions makes earnout payments more onerous for the merged entity than they would have been if the SPAC had retained the full IPO proceeds.

SEC enforcement has tightened SPAC accounting scrutiny

From 2020 onwards, the SEC increased scrutiny of SPAC accounting, particularly around warrant liability measurement and the accounting for contingent and deferred underwriting fees. Several SPACs restated financial statements after the SEC staff commented that warrant fair-value calculations were understated, resulting in overstated earnings. In response, many SPAC sponsors adjusted their warrant models to use more conservative volatility assumptions.

The SEC has also challenged SPAC liability classification in some cases, arguing that warrants should not be treated as liabilities if they are indexed to the SPAC’s own shares. The debate hinges on ASC 815’s derivative guidance and continues to evolve as more SPAC transactions close and the SEC learns how accounting choices influence disclosure and investor decisions.
