On May 19, 2026, the SEC proposed two separate rule changes that together represent the most significant modernization of the registered offering framework in more than twenty years. Operating in coordination with a companion release which proposes to recalibrate public company filer status and expand emerging growth company accommodations, this reform package is designed to dismantle historical regulatory friction, facilitate capital formation, and simplify the compliance architecture for a vast majority of public issuers
In the first of these transformative potential rule changes, the SEC has proposed registered offering reforms that would: (i) increase access to shelf registrations on Form S-3; (ii) allow the use of offering communications that currently are limited to use by well-known seasoned issuers (WKSI) by eliminating the definition of a WKSI for all companies other than foreign private issuers (FPIs) and creating a new set of issuer categories ; (iii) expand the availability of incorporation by reference into Form S-1; and (iv) expand state law preemption to cover all registered offerings.
In two multi-part blog series, I will provide a deep dive into both of these rule proposals starting with the registered offering reform proposal. In Part 1 of the series I provided background and a summary of the proposed rule changes – see HERE. In Part 2 I delved into the proposed changes completely transforming the eligibility requirements and availability to use Form S-3 – see HERE. In this Part 3 I am unpacking the significant changes to the current WKSI structure including the creation of the new Eligible Listed Issuer (ELI) and Seasoned Eligible Listed Issuer (SELI) designations and how that impacts offering communications.
INTRODUCTION
A central pillar of the SEC proposal is a complete overhaul of the offering-process tiers. The Commission proposes to eliminate the long-standing “well-known seasoned issuer” (“WKSI”) designation for all domestic operating issuers, replacing it with a modernized, listing-centric framework.
Since its adoption in 2005, the WKSI classification under Securities Act Rule 405 has functioned as the primary gatekeeper to the most flexible registration and communication accommodations under the federal securities laws. Under current Rule 405, an issuer qualifies as a WKSI if it meets the registrant requirements of Form S-3 (or Form F-3) and, as of a determination date within 60 days of its annual report filing, satisfies either of two financial benchmarks:
- A public float of $700 million or more in common equity securities held by non-affiliates ; or
- The issuance of at least $1 billion in aggregate principal amount of non-convertible securities (other than common equity) in registered primary offerings for cash during the preceding three years.
Historically, WKSIs have utilized these thresholds to command significant structural advantages, notably the ability to file automatic shelf registration statements that are effective immediately upon filing and to utilize “pay-as-you-go” registration fee arrangements.
However, market dynamics and technological advancements have increasingly exposed the limitations of this float-dependent structure. The $700 million public float threshold has functioned as an arbitrary barrier, depriving smaller listed issuers of the ability to raise capital rapidly during favorable market windows. This capital-raising disparity has driven many exchange-listed companies to seek costlier, less transparent private financing alternatives.
To address these imbalances, the Registered Offering Reform Proposal eliminates the WKSI definition for all domestic operating issuers. WKSI status will be retained solely for Foreign Private Issuers (FPIs) filing on Form F-3. This critical distinction preserves the float-based standard for foreign issuers who utilize different reporting regimes or list on international exchanges, maintaining offering efficiency for foreign capital integration. For domestic issuers, the SEC is shifting from a capitalization-based gateway to a regulatory-compliance and exchange-listing model. By focusing on exchange listing and reporting compliance rather than public float, the proposed rules aim to democratize access to the public markets, making execution speed and communication flexibility a standard corporate utility for listed domestic companies.
The Proposed New Three Tier Domestic Offering Framework
The proposed framework collapses the traditional distinctions between S-3 eligible non-WKSIs and WKSIs, establishing three clear, ascending tiers of domestic issuers :
- Form S-3 Eligible Issuers: Issuers that satisfy the streamlined registrant requirements of Form S-3 (which would no longer require a 12-month reporting history or a minimum $75 million public float, provided they are current and timely in their Exchange Act reporting).
- Eligible Listed Issuers (ELIs): Form S-3 eligible operating companies that maintain at least one class of common equity listed on a national securities exchange.
- Seasoned Eligible Listed Issuers (SELIs): ELIs that have additionally been subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act for at least 12 consecutive calendar months.
Under this reorganized hierarchy, approximately 74% of Exchange Act reporting issuers are projected to qualify as SELIs. This represents a dramatic expansion of high-tier registration privileges compared to the approximately 36% of reporting issuers that currently qualify as WKSIs under the $700 million public float standard.
Technical Definitions and Rule 405 Amendments
To implement this framework, the Commission proposes to amend Rule 405 of Regulation C by introducing formal definitions for both ELIs and SELIs.
An Eligible Listed Issuer (ELI) is defined as an issuer that:
- Meets the proposed registrant requirements of Form S-3 (including being current and timely in Exchange Act filings for the preceding 12 months, or such shorter period as required) ;
- Has at least one class of common equity securities listed on a national securities exchange ; and
- Is not a “BSP issuer”—a newly proposed category under Rule 405 that encompasses blank check companies, shell companies (excluding business combination-related shell companies), and penny stock issuers. See Part 2 of this blog series HERE for a full description of a BSP Issuer.
A Seasoned Eligible Listed Issuer (SELI) is defined as an ELI that has additionally been subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act for at least 12 consecutive calendar months.
The determination date for assessing whether an issuer qualifies as an ELI or a SELI is designed to align with current Form S-3 eligibility determination intervals. Specifically, an issuer must measure its status:
- At the time of filing its most recent annual report on Form 10-K; or
- At the time of filing a new registration statement or post-effective amendment to a registration statement.
This alignment ensures consistency and minimizes administrative compliance costs by utilizing existing reporting and filing touchpoints. If an issuer fails to remain current or timely in its periodic filings, or if its common equity is delisted from its national securities exchange, it will lose its ELI or SELI status immediately upon the occurrence of that event or at the next determination date. This all-or-nothing penalty increases the operational stakes for compliance officers and general counsel.
Enhanced Communication Benefits
The proposed rules make sweeping changes to the Securities Act communication rules, which historically restricted information flow during the “quiet period” of a registered offering. By extending WKSI-like communication privileges to all ELIs and Form S-3 eligible issuers, the SEC recognizes that modern digital communication channels ensure sufficient information dissemination.
The following table outlines the enhanced communications framework originally reserved for WKSIs and details how these privileges would be reallocated under the proposed domestic framework :
| Communication Safe Harbor / Rule | Pre-Proposal WKSI Framework | Proposed Domestic Framework |
| Rule 163 (Pre-Filing Communications) | WKSIs only. Permits oral and written offers to sell or solicitations of offers to buy prior to the filing of a registration statement, exempt from Section 5(c) gun-jumping prohibitions, subject to filing and legending requirements. | Extended to all ELIs. Allows listed domestic issuers, regardless of public float or seasoning, to gauge market interest and perform market testing before incurring the costs of filing a registration statement. |
| Rule 163A (Pre-Filing Communications for Form S-8) | WKSIs only. Grants specialized communication safe harbors specifically for offers made in connection with Form S-8 employee benefit plans prior to filing. | Extended to all ELIs. Streamlines equity compensation plan communications for all listed domestic issuers. |
| Rule 164 / Rule 433 (Post-Filing Free Writing Prospectuses) | WKSIs and certain Form S-3 issuers. Permits the use of a Free Writing Prospectus (FWP) after filing a registration statement. WKSIs may use an FWP without delivering or accompanying it with a statutory prospectus. | Extended to all Form S-3 Eligible Issuers. Broadens prospectus-free FWP use to all Form S-3 eligible domestic issuers (including ELIs and SELIs), eliminating physical or electronic prospectus delivery linkages. |
| Rule 139 (Broker-Dealer Research Reports) | WKSIs and Form S-3 issuers meeting transaction requirements. Provides a safe harbor for broker-dealers publishing research on eligible issuers, ensuring the reports do not constitute “offers”. | Extended to all Form S-3 Eligible Issuers. Encourages market research coverage for smaller listed companies by eliminating transaction-specific hurdles. |
These communication safe harbors represent a major step forward for domestic issuers. By allowing ELIs to utilize Rule 163, the SEC provides smaller listed companies with the ability to initiate discussions with institutional investors prior to filing a registration statement. This eliminates the risk of technical gun-jumping violations and allows issuers to structure transactions in response to market feedback. Similarly, the broad expansion of Rule 433 eliminates the requirement to provide an accompanying statutory prospectus alongside an FWP, simplifying investor outreach and lowering transaction execution costs. For more on FWPs, see HERE.
Registered Offering Benefits
The proposal also redistributes the procedural registration advantages historically limited to WKSIs under Rules 413, 430B, 456, 457, and 462. The table below illustrates how registration benefits are distributed across the three new tiers :
| Offering Benefit / Securities Act Rule | Pre-Proposal Rules | Tier 1: Form S-3 Eligible Issuers | Tier 2: Eligible Listed Issuers (ELIs) | Tier 3: Seasoned Eligible Listed Issuers (SELIs) |
| Rule 139 Research Report Exemption | WKSIs and Form S-3 issuers meeting float thresholds ($75M+). | Eligible | Eligible | Eligible |
| Rule 163 Pre-Filing Communications | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 163A Pre-Filing S-8 Communications | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 164 Post-Filing S-8 FWP Use | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 413 Registration of Additional Securities Classes | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 430B(a) Omission of Base Prospectus Info | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 430B(b) Omission of Selling Security Holder Identities | WKSIs and certain Form S-3 issuers. | Eligible | Eligible | Eligible |
| Rule 433 FWP Delivery Exemption | WKSIs and certain Form S-3 issuers. | Eligible | Eligible | Eligible |
| Rule 456(b)/457(r) “Pay-As-You-Go” Fees | WKSIs only. | Ineligible | Eligible | Eligible |
| Rule 462 Automatic Shelf Registration (ASR) | WKSIs only. | Ineligible | Ineligible | Eligible |
This reallocation shifts several procedural benefits down the issuer hierarchy. For example, under the proposed changes to Rule 430B(a), both ELIs and SELIs can omit basic information from their base prospectuses, such as the specific mix of debt and equity securities being registered, which was previously a privilege reserved for WKSIs. Similarly, the ability to register additional classes of securities via an immediately effective post-effective amendment under Rule 413 is extended to ELIs and SELIs, providing these issuers with greater flexibility to adapt their capital-raising strategies to changing market conditions.
Automatic Shelf Registration and Pay-As-You-Go Pricing
The reallocation of Automatic Shelf Registration (ASR) eligibility under Rule 462 and the extension of “pay-as-you-go” filing fees under Rules 456(b) and 457(r) are arguably the most significant changes in the proposed framework.
Under the current system, non-WKSI issuers utilizing standard Form S-3 shelf registration are subject to potential SEC staff review and comment. This process introduces regulatory uncertainty and delays, as an issuer must wait for the SEC to declare its registration statement effective before it can execute a transaction. During this review period, which can range from several days to several weeks, market windows can close, leaving issuers unable to access needed capital.
By extending ASR eligibility to all SELIs under Rule 462, the proposed rules allow approximately 74% of public operating companies to file shelf registration statements that are effective immediately upon filing. This immediate effectiveness removes the SEC review hurdle at the filing stage, allowing issuers to timing-optimize their offerings and execute rapid overnight block trades or capitalize on sudden market surges. Furthermore, SELIs can add new classes of securities or identify selling security holders via post-effective amendments that are also effective immediately, providing complete flexibility in structuring transactions.
Under traditional registration rules, an issuer must pay the SEC filing fee upfront based on the total dollar amount of securities registered on the Form S-3. For smaller or mid-cap issuers registering a $250 million shelf program, this requires a significant, immediate cash outflow for securities that may not be sold for months, or perhaps not at all. This upfront fee ties up corporate liquidity and acts as a capital drag.
The proposed amendments to Rules 456(b) and 457(r) extend the “pay-as-you-go” fee structure to both ELIs and SELIs. Under this framework, eligible issuers can register an unlimited amount of securities on an immediately effective shelf (for SELIs) or a standard shelf (for ELIs) and pay $0 in registration fees at the time of filing. The issuer only pays the registration fee at the time of a shelf takedown, based on the specific amount of securities actually sold. This deferred payment model preserves cash, improves working capital management, and lowers the cost of maintaining a continuous capital-market presence.
Corporate Governance Thoughts
The proposed framework, combined with the elimination of Form S-3’s 12-month seasoning requirement, significantly changes the timeline for newly public companies to access capital. Under current rules, a company must wait a full year after its IPO to utilize Form S-3 and initiate shelf takedowns.
Under the proposed framework, a newly listed company immediately qualifies as an ELI upon completion of its IPO, provided it satisfies the basic registrant requirements. It can immediately implement pre-filing communications under Rule 163, omit details from its base prospectus under Rule 430B(a), and benefit from “pay-as-you-go” pricing to optimize capital management.
Once the company completes its first 12 months of Exchange Act reporting, it transitions to a SELI and gains access to automatic shelf registration. This rapid progression provides late-stage private companies with a clearer and faster path to efficient public capital.
Because ELI and SELI statuses are tied directly to an issuer’s ability to satisfy Form S-3 registrant requirements—such as being current and timely in Exchange Act filings—the cost of a late filing rises significantly.
Under the current system, a late Form 10-Q or Form 10-K filing temporarily restricts an issuer from using Form S-3. Under the proposed rules, a late filing will also immediately strip an issuer of its ELI or SELI status. A SELI that misses a filing deadline would lose its ability to use active ASRs, lose the “pay-as-you-go” fee deferrals, and lose the communication safe harbors under Rules 163 and 164.
This risk places additional pressure on corporate governance and financial reporting controls, as minor accounting delays could impact an issuer’s access to capital markets.
