Introduction
The SEC's January 24, 2024 final SPAC rules represent the most significant regulatory restructuring of the SPAC market since the JOBS Act first enabled the modern SPAC structure. The rules took effect July 1, 2024 and substantially narrowed the SPAC's historical advantages relative to a traditional IPO: the target operating company becomes a co-registrant subject to Section 11 and 12 liability; forward-looking projections in de-SPAC marketing lose the PSLRA safe harbor that operating-company communications enjoy; and disclosure requirements on sponsor conflicts and projections methodology expand meaningfully. The cumulative effect has been to bring de-SPAC mergers much closer to traditional IPO disclosure and liability standards, reducing the structural advantages that drove the 2020-2021 SPAC boom. This article walks through the principal changes and their practical effects.
The Target Company Co-Registrant Provision
The most significant structural change in the 2024 rules is the target company's new status as a co-registrant on the de-SPAC registration statement.
What Co-Registrant Status Means
Before the 2024 rules, the SPAC was the registrant on the Form S-4 for a de-SPAC transaction, with the target operating company providing information for inclusion but not directly subject to securities-law liability for the disclosure. The 2024 rules redefined the target as a co-registrant, meaning the target's officers and directors become directly liable under Sections 11 and 12 of the Securities Act for misstatements or omissions in the registration statement.
- Co-Registrant Status (de-SPAC Target)
The SEC's 2024 SPAC rule provision that designates the target operating company as a co-registrant on the de-SPAC Form S-4 alongside the SPAC. The status makes the target's officers and directors directly liable under Sections 11 and 12 of the Securities Act for material misstatements or omissions in the registration statement, bringing their personal liability profile in line with traditional IPO issuers. Pre-2024, the target was effectively shielded from direct securities-law liability for the de-SPAC disclosure; post-2024, that shield is gone.
Bringing Target Liability in Line with IPO Issuers
The change brings the target's liability profile in line with a traditional IPO issuer's. In an IPO, the issuer's officers and directors sign the registration statement and are personally liable for material misstatements. In a pre-2024 de-SPAC, the target's officers and directors did not sign the SPAC's registration statement and were not directly liable in the same way. The 2024 change closes this gap, making the target's executives subject to the same liability exposure as IPO executives.
Practical Consequences
The new liability profile has reshaped how target operating companies approach de-SPAC due diligence and disclosure. Targets now run more rigorous internal disclosure processes, retain independent counsel more aggressively, and accept more conservative disclosure language than the pre-2024 SPAC market accepted. The principal beneficiaries are public shareholders who now have stronger legal recourse against the target's executives if the merger's disclosure proves inaccurate.
The PSLRA Safe Harbor Elimination
The Private Securities Litigation Reform Act of 1995 created a safe harbor for forward-looking statements made by public companies, protecting them from securities-litigation liability if the statements were accompanied by meaningful cautionary language. Before the 2024 rules, this safe harbor applied to SPAC and de-SPAC communications.
What the Safe Harbor Provided
The PSLRA safe harbor was central to the SPAC's historical advantage in marketing forward-looking projections. Pre-2024 SPAC sponsors and target companies could include detailed multi-year projections in the de-SPAC marketing materials with reduced fear of post-merger securities litigation if the projections proved inaccurate. The safe harbor protected aspirational marketing that an IPO disclosure regime would not have permitted.
- PSLRA Safe Harbor (Post-2024 SPAC Context)
The Private Securities Litigation Reform Act of 1995 safe harbor for forward-looking statements protects most public-company communications from securities-litigation liability if the statements include meaningful cautionary language. The 2024 SEC SPAC rules eliminated this safe harbor for SPAC and de-SPAC transactions, meaning forward-looking projections in de-SPAC marketing now face the same liability standards as traditional IPO communications. The elimination has been the single most consequential 2024 change for SPAC market dynamics.
What the 2024 Rules Eliminated
The 2024 rules made the PSLRA safe harbor unavailable to SPACs and de-SPAC transactions. Forward-looking statements in de-SPAC marketing now face the same liability standards as traditional IPO communications, where the issuer must defend the statements as reasonable based on the information available at the time. The change eliminates one of the SPAC's most distinctive marketing advantages.
Cautious Projections in Practice
Post-July 2024 de-SPAC marketing has become noticeably more conservative on forward-looking statements. Sponsors and targets present projections more cautiously, with extensive cautionary language and explicit reservations. The change has narrowed the gap between de-SPAC and IPO marketing materials substantially, reducing one of the principal reasons that capital-intensive operating companies chose the SPAC path.
Expanded Disclosure Requirements
Beyond the co-registrant and PSLRA changes, the 2024 rules expanded several specific disclosure categories.
Sponsor Conflicts Disclosure
The rules require detailed disclosure of the sponsor's economic interests, including the promote economics, any compensation arrangements with the target, prior relationships between the sponsor and target, and any indirect benefits the sponsor receives from completing the merger. The disclosure makes the sponsor's economics meaningfully more visible to public shareholders evaluating the de-SPAC.
Projections Methodology Disclosure
If the de-SPAC marketing includes forward-looking projections, the rules require detailed disclosure of the methodology, the principal assumptions, and the historical financial context that supports the projections. Issuers cannot simply present projected revenue and EBITDA without explaining how those numbers were derived and what assumptions support them.
Risk Factor Disclosure
The rules expanded risk factor requirements specifically for de-SPAC transactions, including risks related to the SPAC structure (sponsor conflicts, redemption mechanics, warrant overhang), the merger consideration, and the post-merger operating company's prospects. Risk-factor sections in post-2024 de-SPAC filings have grown noticeably longer than pre-2024 disclosures.
Management Disclosure on Projections and PCAOB Audit of Historical Results
The rules require disclosure by management of the material bases and assumptions underlying any projections used in the de-SPAC marketing under new Regulation S-K Item 1609. Because the target is now a co-registrant, its historical financial statements must also be PCAOB-audited. Auditors verify historical results; they do not opine on forward-looking projections. The combined effect has added cost and time to the de-SPAC preparation process.
| Dimension | Pre-2024 SPAC Regime | Post-July 2024 Regime |
|---|---|---|
| Target liability | Indirect, through SPAC | Direct, target as co-registrant |
| PSLRA safe harbor | Available for projections | Eliminated for SPAC and de-SPAC |
| Sponsor conflicts disclosure | General disclosure required | Detailed itemized disclosure |
| Projections methodology | Limited disclosure | Methodology + assumptions disclosed by management (Item 1609) |
| S-4 risk factors | Standard | Expanded SPAC-specific disclosures |
| Auditor role on projections | Not required | Not required (auditors verify historical results only; PCAOB audit of target financials required as co-registrant) |
How the 2024 Rules Have Reshaped the Market
The cumulative effect of the 2024 changes has been a substantial restructuring of the SPAC market.
Decline in SPAC IPO Issuance
SPAC IPO volumes peaked in 2020-2021 and have declined materially since, with the 2024-2025 environment showing meaningfully lower SPAC IPO activity than the boom era. The decline reflects multiple factors (rising interest rates making the trust-yield trade more attractive than completing risky mergers, post-2022 underperformance of de-SPAC stocks, broader market conditions), but the 2024 SEC rules have been a significant contributor by reducing the SPAC's structural advantages.
Higher Quality Sponsor and Target Profiles
Surviving SPAC sponsors in the post-2024 environment tend to be institutional sponsors with strong track records and specific industry expertise. The lower-quality first-time sponsors that proliferated in 2020-2021 have largely exited the market. Surviving target companies that choose the SPAC path tend to be those for whom the speed and price-certainty advantages still justify the structural costs even at the higher 2024 disclosure and liability standards.
Shift Toward More Disciplined Structures
Post-2024 SPAC structures have evolved toward smaller promotes (often 15-18 percent rather than the historical 20 percent), fewer warrants, longer sponsor earnouts, and tighter alignment between sponsor and target incentives. The disciplined structures reflect a market that has been forced to compete on terms with traditional IPOs rather than relying on structural arbitrage.
Renewed Interest as the Market Stabilizes
By late 2025, the SPAC market had stabilized at a lower equilibrium that reflects the post-2024 structural environment. New SPAC IPO activity, while well below the 2020-2021 peak, has resumed at meaningful volumes, and dual-track processes increasingly include a SPAC option alongside the traditional IPO and M&A tracks. The market has matured rather than disappeared.
Co-registrant liability, no PSLRA shield, expanded conflicts disclosure: the 2024 rules narrowed enough of the SPAC's structural edge that the path now competes with a traditional IPO on something close to even ground. Whether SPAC or IPO actually wins the mandate for any given issuer is the comparative judgment the SPAC vs traditional IPO decision framework is designed to support.
