On May 19, 2026, the Securities and Exchange Commission (SEC) proposed a broad set of amendments that would significantly restructure the registered offering framework for domestic reporting companies.
If adopted, the proposal would expand eligibility to use Form S-3 and conduct shelf offerings. It would also extend registration and communication flexibility to additional public companies and modernize registered offering rules and processes.
The proposal represents a shift toward treating shelf access and offering flexibility as baseline features of public company status rather than benefits reserved for well-known seasoned issuers (WKSIs).
Key Elements of the Proposal
Expansion of Form S-3 Eligibility
The proposal would significantly broaden access to Form S-3 for primary offerings.
Current rules require at least 12 months of Exchange Act reporting and a $75 million public float for unlimited primary offerings. Issuers not meeting these thresholds are generally limited to Form S-1 and cannot conduct traditional shelf or at-the-market offerings.
The proposal would:
- Remove the 12-month reporting “seasoning” requirement.
- Eliminate the $75 million public float threshold for primary offerings.
- Eliminate the “baby shelf” limitation, including the one-third public float cap for smaller issuers.
As a result, any reporting issuer that is current and timely in its Exchange Act filings would generally be eligible to use Form S‑3 for primary offerings regardless of size. The SEC estimates that the changes would extend Form S‑3 eligibility by approximately 60%.
Implication: Many issuers could transition from Form S-1 to a shelf-based capital-raising model, enabling opportunistic and repeated access to the public markets.
Replacement of WKSI Framework
The WKSI framework would be retained only for foreign private issuers (FPIs) in light of the SEC’s 2025 FPI Concept Release.
The proposal would replace the current WKSI framework—under which WKSI status requires a public float of $700 million or more, or $1 billion in registered nonconvertible debt—with a tiered structure organized around three new issuer categories:
- Form S-3-Eligible Issuers.
- Eligible Listed Issuers (ELIs).
- Seasoned Eligible Listed Issuers (SELIs).
At the base tier, any reporting issuer that is current and timely in its Exchange Act filings would qualify as a Form S-3-eligible issuer, gaining access to shelf registration on Form S-3 regardless of public float or market capitalization.
At the next tier, an ELI would be any Form S‑3-eligible issuer with at least one class of common equity listed on a national securities exchange. ELIs would receive enhanced registration and communication benefits currently available only to WKSIs, including the ability to engage in prefiling communications under Rule 163, use of expanded free writing prospectuses under Rule 433, post-effective amendment flexibility under Rule 413, the ability to omit certain prospectus information under Rule 430B(a), and pay-as-you-go filing fees under Rules 456(b) and 457(r).
At the highest tier, a SELI would be an ELI with at least 12 months of Exchange Act reporting history. Only SELIs would be eligible for automatic shelf registration. The SEC estimates that approximately 74% of Exchange Act reporting issuers would qualify as SELIs, compared with approximately 36% that currently qualify as WKSIs. Like existing WKSIs, SELIs could file automatically effective shelf registration statements.
Implication: The practical distinctions between WKSIs and other reporting issuers would narrow significantly, with more companies able to access flexible offering frameworks. The WKSI definition would be retained only for foreign private issuers.
Consistent with the operating company reforms, the proposal would extend the ELI/SELI tiered framework to business development companies (BDCs) and registered closed-end funds (affected funds) using Form N-2. Short-form Form N-2 eligibility would be expanded to any exchange-listed affected fund that is current in its Exchange Act reporting, eliminating the current public float threshold and Exchange Act reporting history requirement.
For registered closed-end funds (CEFs), the proposal would also remove the additional requirement of 12 months of registration under the Investment Company Act. ELI affected funds would receive communication flexibility, the ability to register additional securities classes, and pay-as-you-go fees, while automatic shelf registration would remain available only to SELI affected funds. The proposal would also preempt state blue sky requirements for nontraded BDCs issuing securities publicly.
Implication: Exchange-listed BDCs and CEFs that lack WKSI status but are current in their reporting would gain significant new shelf registration and communication flexibility.
Modernization of Form S-1
The proposal would expand incorporation by reference on Form S‑1, including extending forward incorporation by reference—currently available only to smaller reporting companies—to all eligible issuers. It would also eliminate the requirement to have filed a Form 10-K for the most recently completed fiscal year as a condition to incorporation by reference.
Implication: For issuers not yet eligible to use Form S-3, the changes could reduce duplication, streamline offering updates, and narrow the practical gap between Form S-1 and Form S-3 transactions.
Ineligible Issuer Provisions and SPAC Treatment
The proposal would consolidate and clarify existing restrictions on issuers that pose heightened regulatory concerns.
“BSP Issuers” (blank check companies, shell companies, and penny stock issuers) and their subsidiaries would be expressly prohibited from using Form S-3 and would be ineligible to incorporate by reference on Form S-1. A three-year lookback would continue to apply in determining whether an issuer or any of its predecessors was a shell company or blank check company.
The proposal would also bar certain “bad actors” from using Form S-3, including issuers or subsidiaries convicted within the past three years of felonies or misdemeanors involving securities fraud, false filings, or bribery, as well as issuers subject to certain administrative orders or industry bars.
Notably, former special purpose acquisition companies (SPACs) would not be deemed shell companies solely because they or their predecessors were a SPAC, provided the issuer is not a shell company at the time of filing. This would allow de-SPAC companies to access Form S-3 without a three-year waiting period after a business combination.
Implication: De-SPAC companies and other issuers emerging from shell company status should evaluate whether the proposed SPAC exception would affect their capital-raising strategies. Issuers with potential bad actor issues should assess whether the expanded disqualification provisions could limit their access to Form S-3.
Expansion of Research Safe Harbors
The proposal would amend Securities Act rules governing broker-dealer research (Rules 137, 138, and 139) to expand safe harbors. Rules 137 and 138 would be simplified by replacing current eligibility conditions with a prohibition on research reports regarding BSP issuers. Rule 139 would be expanded to cover any Form S‑3-eligible issuer, rather than only WKSIs, allowing broader research coverage without triggering Securities Act “offer” concerns.
Implication: Expanded research safe harbors may affect launch timing and coordination with underwriters, particularly for issuers that currently receive limited research coverage.
Blue Sky Preemption for Registered Offerings
The proposal would preempt state securities law registration and qualification requirements for all registered offerings by adding a new definition of “qualified purchaser” under Section 18(b)(3) of the Securities Act. States would retain enforcement authority over fraud and deceit, as well as the ability to require notice filings and collect fees.
Implication: This change would reduce complexity and execution risk associated with multistate offerings, while leaving the federal disclosure and liability frameworks unchanged.
Technical and Conforming Amendments
The proposal also includes a range of technical changes.
It would reverse the default under Rule 473 so that registration statements would be deemed to include a delaying amendment unless the issuer affirmatively opts out. It would also update the rules governing the age of financial statements and make conforming changes across Securities Act rules governing offering communications, free writing prospectuses, and shelf procedures.
Practical Implications for Public Companies
If adopted, the proposal would have immediate implications for capital markets strategy and disclosure practices:
- Shift to shelf readiness. Many issuers that are currently ineligible for Form S-3 would gain the ability to maintain an effective shelf registration statement and access capital more opportunistically.
- Increased transaction cadence. Easier access to shelf takedowns and at-the-market (ATM) programs may increase the frequency and speed of public offerings.
- Enhanced communications flexibility. Expanded offering communications may require updates to internal disclosure controls and coordination with underwriters and analysts.
- Reduced structural constraints. Elimination of the baby shelf limitation would remove a key constraint on capital raising by smaller issuers.
- Simplified execution. Blue sky preemption and technical changes simplify executing registered offerings.
Next Steps
Public companies should consider whether they would become newly eligible to use Form S-3 under the proposal and whether existing disclosure controls and governance processes support a “readiness” approach to capital raising.
They should also consider how expanded offering and research communication flexibilities may affect internal policies, and whether to submit comments on the scope of the proposed eligibility changes and the design of the proposed replacement of the WKSI framework.
The proposal will be subject to a 60-day public comment period following publication in the Federal Register and may be revised before adoption. Companies should consider whether to submit a comment letter to the SEC.
