SEC Rule 251

Overview and Regulatory Purpose

The Securities Act of 1933 requires, as a general matter, that any offer or sale of a security to the public be preceded by the filing of a registration statement with the Commission and the delivery of a prospectus to purchasers. 

The registration process is comprehensive, expensive, and time-consuming, and for smaller companies — particularly those seeking to raise amounts in the range of tens of millions of dollars rather than hundreds of millions — the cost of full registration can represent a significant and potentially prohibitive fraction of the anticipated offering proceeds. 

The securities laws have always recognised this disproportionality and provided relief from the full registration requirement for small offerings, but for decades the available exemptions were poorly calibrated to the actual needs of the market: traditional Regulation A, as it existed prior to the 2015 amendments, capped offerings at $5 million — a limit set in 1992 that bore no relationship to the economics of capital formation in the modern market — while Regulation D offered no offering size limit but restricted participation to accredited investors, excluding retail investors from access to private placement opportunities.

Regulation A as reformed by the JOBS Act of 2012 and the Commission's 2015 implementing rules was designed to fill the gap between these two frameworks. By providing a pathway to raise up to $75 million annually from both accredited and non-accredited investors — including members of the general public — while imposing disclosure and reporting obligations meaningfully lighter than those required of Exchange Act reporting companies, the Commission created what practitioners quickly termed a "mini-IPO" framework. 

The investor-facing disclosure document — the offering circular — is less detailed and less expensively prepared than a full Securities Act prospectus, but it is publicly filed with the Commission and subject to Commission staff review, providing a level of investor protection that Regulation D's pure exemption from registration does not replicate. 

Regulation A also preserves one of the most significant features of a registered offering: securities sold in Tier 2 offerings are freely tradable, rather than restricted, providing investors with liquidity that Regulation D investors typically do not receive.

Rule 251 is the provision that defines the outer boundaries of this framework — determining who is in and who is out, how much can be raised, and under what conditions the exemption is available.

Statutory Authority and Rulemaking History

Rule 251 derives its statutory authority from Section 3(b) of the Securities Act of 1933, which grants the Commission authority to exempt certain classes of securities from the Act's registration requirements by rule, subject to conditions prescribed to protect the public interest and the interests of investors. Section 3(b)(1) provides authority for small offering exemptions not exceeding $5 million — the original Regulation A framework. 

Section 3(b)(2) was added by Section 401 of the Jumpstart Our Business Startups Act of 2012 and provides authority for expanded exemptions up to $50 million, subject to enhanced conditions including mandatory filing of audited financial statements and ongoing reporting. The Commission's authority to raise the Tier 2 ceiling beyond the JOBS Act's $50 million threshold was subsequently confirmed by the Economic Growth, Regulatory Relief, and Consumer Protection Act of 2018, which directed the Commission to review the Tier 2 offering limit and authorised an increase.

The modern Regulation A framework was adopted in Securities Act Release No. 33-9741, published March 25, 2015, and effective June 19, 2015, in what market participants widely refer to as the Regulation A-plus rulemaking. 

The 2015 rulemaking replaced the pre-existing Regulation A — which had been in place in a limited form since 1936 and whose $5 million offering ceiling had rendered it economically irrelevant to most issuers — with a comprehensive two-tier framework. 

Tier 1 preserved the original structure of Regulation A at an updated $20 million offering ceiling with state law preemption only for exchange-listed securities. Tier 2 introduced a more ambitious framework with a $50 million offering ceiling, federal preemption of state blue sky registration requirements, mandatory audited financial statements, and ongoing periodic reporting obligations modelled on, but lighter than, Exchange Act reporting.

The Commission amended Rule 251 in Securities Act Release No. 33-10734, effective March 15, 2021, as part of the broader Exempt Offering Framework rulemaking. The most consequential change in that amendment was the increase of the Tier 2 offering ceiling from $50 million to $75 million in any 12-month period, reflecting the Commission's assessment that the original JOBS Act ceiling had become a binding constraint on economically significant offerings and that the expansion was warranted by the market's demonstrated capacity to absorb Tier 2 issuances. The 2021 amendments also adjusted the affiliate resale limits under both tiers. The eCFR confirms Rule 251 was last amended on January 14, 2021, with no further changes through June 2026.

Key Provisions and Operative Requirements

Rule 251(a) establishes the core offering parameters. Under Tier 1, an issuer may offer and sell up to $20 million of securities in any 12-month period, including no more than $6 million on behalf of selling securityholders that are affiliates of the issuer. Under Tier 2, an issuer may offer and sell up to $75 million of securities in any 12-month period, including no more than $22.5 million on behalf of affiliated selling securityholders. In both tiers, sales by all selling securityholders are limited to no more than 30% of the total offering in any particular offering. The 12-month calculation is rolling, meaning that prior Regulation A sales within the 12 months preceding the commencement of a new offering reduce the capacity available under the new offering ceiling. An issuer of $20 million or less of securities may elect to proceed under either Tier 1 or Tier 2, with the election carrying different disclosure, state law, and investor protection consequences depending on which tier is chosen.

Rule 251(b) establishes issuer eligibility. The exemption is available only to companies organised in and with their principal place of business in the United States or Canada. Foreign private issuers, investment companies registered under the Investment Company Act of 1940, and business development companies as defined in that Act are ineligible. Blank check companies — entities with no specific business plan or purpose, or whose plan is to engage in a merger or acquisition with an unidentified company — are also excluded from Regulation A. Issuers that are subject to the ongoing reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934 are ineligible to use Regulation A while those obligations remain in effect, reflecting the Commission's view that Exchange Act reporting issuers already have access to the registered offering framework and do not require Regulation A's lighter alternative pathway.

Rule 251(d) addresses the mechanics of the offering process. All offers and sales under Regulation A must be made pursuant to an offering statement that has been qualified by the Commission, meaning that the Commission staff has completed its review and determined that the offering may proceed. The offering statement is filed on Form 1-A and consists of the offering circular — the principal disclosure document — together with financial statements and exhibits. Securities sold under a Regulation A offering may only be sold during the period from qualification to three years after the initial qualification date; issuers wishing to continue selling beyond that period must file a new offering statement covering the additional securities. Rule 251(d) also provides that offers — though not sales — may be made prior to qualification of the offering statement, subject to certain restrictions on the form those pre-qualification communications may take, reflecting the testing the waters provisions addressed in Rule 255.

Rule 251(b) also addresses the critical question of bad actor disqualification. Any issuer, affiliated seller, director, officer, general partner, managing member, or beneficial owner of 20% or more of the issuer's voting equity securities whose participation in the offering would trigger a bad actor disqualification event — including prior Commission enforcement actions, court injunctions, final orders by certain regulatory authorities, criminal convictions, and other defined triggering events — renders the issuer ineligible for the Regulation A exemption with respect to that offering. The Commission may waive the disqualification upon a showing of good cause.

Rule 251(e) establishes the ongoing availability of the exemption. A failure to comply with a term, condition, or requirement of Regulation A does not result in the automatic loss of the exemption for an offer or sale to a particular investor if the issuer can establish that the failure did not pertain to a requirement directly intended to protect that investor, the failure was insignificant with respect to the offering as a whole, and the issuer made a good faith and reasonable attempt to comply. However, failures to comply with Rule 251(a) — the offering size limits — Rule 251(b) — the eligibility requirements — and Rule 251(d)(1) and (d)(3) — the qualification and sales restrictions — are deemed per se significant failures that cannot be cured under the insignificance exception.

Scope of Application

Rule 251's Regulation A framework is available to eligible issuers as an alternative to full Securities Act registration for public offerings. It permits both accredited and non-accredited investors to participate, distinguishing Regulation A from Regulation D and making it the only SEC-sanctioned framework through which non-accredited members of the retail public can participate in an exempt offering of securities that are also freely tradable. Under Tier 2, non-accredited investors who are natural persons are subject to investment limitations: they may not invest more than 10% of the greater of their annual income or net worth in any Regulation A Tier 2 offering during any 12-month period. This limitation does not apply to accredited investors or to securities that will be listed on a national securities exchange upon qualification. No investment limitation applies to Tier 1 purchasers, reflecting the more limited scope of Tier 1 offerings and the continued availability of state blue sky review as a supplementary investor protection mechanism.

The state law implications of the Tier 1 and Tier 2 distinction are among the most consequential practical differences between the two pathways. Securities sold in Tier 2 offerings are covered securities under the National Securities Markets Improvement Act of 1996, preempting state securities registration and qualification requirements entirely. Tier 1 securities are not covered securities and remain subject to state blue sky review in each state where they are offered and sold — a requirement that can significantly increase the cost and complexity of a Tier 1 offering, particularly for issuers seeking to access investors across multiple states.

Relationship to Related Rules and Regulations

Rule 251 functions as the gateway to Rules 252 through 263, which together constitute the full Regulation A framework. Rule 252 governs the content and filing of the offering statement; Rule 253 specifies the offering circular requirements; Rule 255 addresses testing the waters communications before and after filing; and Rule 257 governs the periodic and current reporting obligations that apply to Tier 2 issuers following qualification. An issuer that satisfies Rule 251's eligibility and offering parameter conditions is subject to all of these companion rules as conditions of maintaining the exemption.

Rule 251's accredited investor cross-references connect directly to the definition in Rule 501(a) as incorporated by Rule 215, ensuring that the accredited investor concept carries a consistent meaning across Regulation A, Regulation D, and the Securities Act's broader framework. The Tier 2 investment limitation applicable to non-accredited natural persons similarly cross-references Rule 501(a) for the definition of accredited investor and uses the same income and net worth measures that define eligibility under Regulation D.

Rule 251's bad actor disqualification provisions mirror those applicable under Rule 506(d) of Regulation D, reflecting the Commission's effort in the 2015 rulemaking to harmonise disqualification standards across the exempt offering framework. The integration provisions applicable to Regulation A connect to the broader integration safe harbour established in Rule 152, which determines when a Regulation A offering is treated as part of the same transaction as a concurrent Regulation D or registered offering.

Amendment History and Regulatory Evolution

The history of Rule 251 tracks the history of Regulation A itself, which was among the earliest and longest-standing exemptions in the Securities Act's framework. Original Regulation A, adopted in the 1930s, provided relief from registration for small offerings in amounts measured in thousands rather than millions of dollars. The $5 million ceiling established in 1992 represented the last substantive amendment to the framework before the JOBS Act mandate of 2012. The prolonged inadequacy of the pre-2015 ceiling — and the consequent irrelevance of Regulation A to most issuers — shaped the Commission's approach to the 2015 rulemaking, which was explicitly designed to create a genuinely usable alternative to both full registration and pure private placement.

The 2021 increase of the Tier 2 ceiling to $75 million was the most significant amendment since the framework's 2015 overhaul. The March 2025 Regulation A offering by Newsmax Media — which raised the full $75 million Tier 2 maximum and subsequently listed on the New York Stock Exchange — represented the largest Regulation A offering in the exemption's history and demonstrated that the $75 million ceiling can support transactions of genuine market significance. That transaction has sharpened attention on whether the current ceiling continues to serve the Commission's capital formation objectives or whether further increases are warranted.

The Commission's September 2025 regulatory agenda, reflecting Chair Atkins's stated priority of reinvigorating the capital formation framework, explicitly flagged updates to the exempt offering pathways as an area of forthcoming rulemaking activity. Chair Atkins has specifically questioned the adequacy of the Tier 2 offering limit and the overall utilisation trajectory of Regulation A, which data released by the Division of Economic and Risk Analysis in May 2025 showed declining from 307 qualified offerings in 2022 to 102 in 2024. No formal rulemaking proposing amendments to Rule 251 has been published in the Federal Register as of June 2026. The INVEST Act, which passed the House of Representatives in December 2025 by a bipartisan 302-123 vote, includes provisions addressing the exempt offering framework but had not been enacted into law as of June 2026.

Enforcement Context and SEC Action Patterns

Enforcement actions arising from Regulation A violations most commonly involve issuers who have misused the exemption — either by exceeding the offering size limits under Rule 251(a), by failing to qualify offering statements prior to commencing sales, by offering securities to investors in jurisdictions where blue sky compliance was required and not obtained for Tier 1 offerings, or by failing to disclose bad actor disqualification events that would have rendered the issuer ineligible for the exemption.

The Commission's Division of Enforcement has brought actions against issuers who conducted unqualified Regulation A offerings — treating pre-qualification testing-the-waters communications as sales rather than offers — and against promoters who misrepresented the terms of Regulation A offerings in marketing materials directed at retail investors. Given Regulation A's explicit accessibility to non-accredited investors, the Division has treated investor protection in the Regulation A context with particular seriousness, recognising that retail participants in Tier 2 offerings may have less capacity to independently assess issuer disclosure than the institutional investors who dominate the Regulation D and registered offering markets.

The Office of Examinations has included broker-dealer compliance with Regulation A offering mechanics, including the prohibition on sales prior to qualification and the enforcement of the Tier 2 investment limitations applicable to non-accredited investors, in its examination priorities for firms that act as placement agents or broker-dealers in Regulation A transactions. Commission staff have also emphasised, in Compliance and Disclosure Interpretations, the importance of accurate disclosure in Form 1-A offering statements and the issuer's ongoing obligation to update its disclosure through post-qualification amendments when material changes in its business or financial condition occur.

Examination Relevance and Key Takeaways

Rule 251 and the Regulation A framework are tested at the Series 7 and SIE levels in the context of exempt offering mechanics and the available alternatives to full Securities Act registration. Candidates should understand the two-tier structure — Tier 1 at $20 million annually with state blue sky exposure, Tier 2 at $75 million annually with federal preemption of state law — and the core eligibility restrictions, including the ineligibility of foreign private issuers, registered investment companies, blank check companies, and Exchange Act reporting issuers. The 10% investment limitation applicable to non-accredited natural person investors in Tier 2 offerings is a consistently tested concept, as is the distinction between Regulation A's open-to-the-public structure and Regulation D's accredited-investor-only framework for Rule 506(c) offerings.

Candidates at the Series 65 and Series 66 level should understand Regulation A in the context of investment adviser obligations when advising clients on participation in Regulation A offerings, including the suitability considerations applicable to non-accredited investors who are subject to the 10% investment cap and the liquidity implications of the difference between Tier 2's freely tradable securities and Regulation D's restricted securities.

The key points to retain are these. Rule 251 establishes the eligibility conditions and offering parameters for Regulation A, the Commission's mini-IPO framework for smaller issuers. Tier 1 permits offerings of up to $20 million annually and subjects securities to state blue sky review. 

Tier 2 permits offerings of up to $75 million annually and preempts state blue sky registration requirements. Both tiers are open to accredited and non-accredited investors, including retail members of the public; non-accredited natural person investors in Tier 2 offerings are limited to investing no more than 10% of the greater of their annual income or net worth. Eligible issuers are limited to U.S. and Canadian entities that are not investment companies, blank check companies, foreign private issuers, or Exchange Act reporting companies. 

All offerings require Commission qualification before sales may commence. The Tier 2 ceiling was increased from $50 million to $75 million in March 2021. 

No formal amendments to Rule 251 are pending as of June 2026, though the Commission's September 2025 regulatory agenda and Chair Atkins's public statements indicate active review of the exempt offering framework, and the INVEST Act passed the House in December 2025 with provisions addressing exempt offering pathways.
