SEC Rule 134

By carving out this narrow category of factual, non-promotional announcement from the broad statutory definition of prospectus, Rule 134 enables the financial markets to function with basic transparency about pending offerings — informing investors, analysts, and the financial press that a registered offering has commenced — without compromising the gun-jumping framework's core objective of channelling the persuasive, marketing-oriented communications used to sell securities through the formal disclosure document that Section 10 requires.

Overview and Regulatory Purpose

Section 5 of the Securities Act prohibits the use of any prospectus relating to a security unless that prospectus meets the requirements of Section 10. Because Section 2(a)(10)'s statutory definition of prospectus is extraordinarily broad — encompassing any written communication that offers a security for sale — a literal application of this framework would prohibit virtually any written reference to a pending registered offering unless that reference satisfied Section 10's full content requirements, including the comprehensive financial and business disclosure that a complete statutory prospectus must contain.

This rigidity would prevent issuers and underwriters from even announcing that a registration statement had been filed, depriving the market of basic information about pending offerings that would otherwise be readily and legitimately available.

Rule 134 addresses this rigidity by carving out a narrow category of permitted communication — limited to specified factual identifying information about the offering — that falls outside the prospectus definition entirely, allowing issuers and underwriters to make basic announcements without triggering Section 10's full disclosure obligations.

The rule's design reflects a careful calibration: the permitted content is narrow enough that a Rule 134 notice cannot function as a substitute for the actual prospectus or as a vehicle for persuasive sales communication, while still being broad enough to convey the basic factual information — the issuer's identity, the type and amount of securities, the offering's general timing, and the identity of the underwriters — that legitimately informs market participants that an offering is occurring. 

The rule's historic association with the tombstone advertisement format — a simple, text-only notice traditionally published in financial newspapers such as The Wall Street Journal — reflects this calibration: the format's stark, unembellished presentation of basic facts, without persuasive language, photographs, or marketing copy, is itself emblematic of the narrow factual category that Rule 134 permits.

Statutory Authority and Rulemaking History

Rule 134 derives its statutory authority from Sections 2(a)(10), 5, and 19(a) of the Securities Act of 1933. Section 2(a)(10) provides the statutory definition of prospectus from which Rule 134 carves its exclusion; Section 5 establishes the gun-jumping prohibition that the rule's exclusion relieves; and Section 19(a) provides the Commission's general rulemaking authority to define terms and prescribe rules implementing the Act's provisions.

Rule 134 has existed in the Commission's General Rules and Regulations since well before the modern offering communications framework, historically operating as the principal safe harbour through which issuers and underwriters could publish tombstone advertisements identifying a pending registered offering. 

The rule was comprehensively revised as part of the Securities Offering Reform rulemaking — Securities Act Release No. 33-8591, published at 70 FR 44722, August 3, 2005 — the same landmark rulemaking that introduced the well-known seasoned issuer concept, automatic shelf registration, and the free writing prospectus framework of Rules 163, 164, and 433. 

The 2005 reform expanded the category of routine information that issuers and offering participants could communicate under Rule 134 without that communication constituting a prospectus, eliminated certain prior requirements — including the requirement to reference state securities laws and to specify whether the financing was a new financing or a refunding — and modernised the rule's prospectus delivery accommodation to reflect electronic communication, permitting Rule 134 notices to identify from whom, and include a URL where, a statutory prospectus could be obtained, and confirming that the requirement for a Section 10 prospectus to accompany or precede certain Rule 134 communications could be satisfied electronically through an active hyperlink.

Rule 134 was subsequently amended August 3, 2011 — 76 FR 46617 — and again June 1, 2020 — 85 FR 33352 — as part of the Commission's Exempt Offering Framework rulemaking, which harmonised various exemptive and communications provisions across the Securities Act's offering framework. No further amendments to Rule 134 have been adopted through June 2026.

Key Provisions and Operative Requirements

Rule 134(a) establishes the foundational availability condition and the comprehensive list of permitted content categories. Except as provided in Rule 134(e) and (g), the terms prospectus as defined in Section 2(a)(10) of the Act and free writing prospectus as defined in Rule 405 shall not include a communication limited to the statements required or permitted by Rule 134, provided that the communication is published or transmitted to any person only after a registration statement relating to the offering — including a prospectus satisfying the requirements of Section 10 of the Act, except as otherwise permitted in Rule 134(a) — has been filed. 

This availability condition is critical: Rule 134 cannot be used before a registration statement containing a Section 10 prospectus has been filed, distinguishing it from Rule 135's notice of proposed offering safe harbour, which is available even before any registration statement has been filed.

The enumerated permitted content categories under Rule 134(a) include, among others: the name of the issuer; the title, amount, and basic terms of the securities being offered; a brief indication of the general type of business of the issuer; the price of the security, or the method by which the price will be determined, if not disclosed; the names of the underwriters participating in the offering; the dates and approximate timing of the offering; whether the securities are being offered in connection with a distribution by selling securityholders; a brief statement of the manner and purpose of the offering without setting forth the terms; whether the security is being offered in exchange for other securities; and any statement or legend required by state law or administrative authority, among numerous other narrowly defined categories of basic identifying information.

 Each of these categories is deliberately factual and identifying in character rather than persuasive or promotional — Rule 134 does not permit, for example, the inclusion of photographs of investment properties, descriptions of tax benefits associated with the investment, or any other content designed to encourage a favourable view of the offering's merits beyond its basic identifying characteristics.

Rule 134(c) addresses the prospectus accompaniment requirement applicable to certain categories of Rule 134 communication. Where a Rule 134 notice includes content beyond the most basic identifying categories — most significantly, where the notice states the price of the security — the notice must be accompanied or preceded by a Section 10 prospectus, or, following the 2005 reform's modernisation, must state from whom, and include a URL where, a statutory prospectus may be obtained. 

Rule 134(c)(1)'s electronic accommodation confirms that the requirement for a Section 10 prospectus to accompany or precede certain Rule 134 notices may be satisfied in an electronic communication through an active hyperlink to the prospectus, paralleling the equivalent accommodation that Rule 433 provides for free writing prospectuses. 

A URL address to the statutory prospectus that is not formatted as an active hyperlink in an electronic communication does not satisfy this requirement — the prospectus must be genuinely and immediately accessible through the hyperlink's function, not merely referenced by an inactive text string that the recipient would need to separately copy and navigate to.

Rule 134's required legend — applicable to notices that include pricing or other content triggering the prospectus accompaniment requirement — states substantially that a registration statement relating to the securities has been filed with the Commission but has not yet become effective, and that the securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. 

This legend directly parallels the cautionary language that Rule 430's preliminary prospectus framework requires and reinforces the gun-jumping framework's central message — that the registration process remains incomplete and no binding sales may occur — even as the Rule 134 notice itself conveys basic offering information to the market.

Rule 134(e) and Rule 134(g) establish specific exclusions and limitations on the rule's general availability. Rule 134(g) specifically provides that the rule does not apply to a communication relating to an investment company registered under the Investment Company Act of 1940, other than a registered closed-end investment company — reflecting the Commission's determination, following extensive industry comment, that open-end mutual funds should rely on the dedicated advertising framework of Rule 482 rather than Rule 134's tombstone notice exclusion, while closed-end funds — whose offering structure more closely resembles conventional operating company offerings — remain eligible to use Rule 134.

Scope of Application

Rule 134 is available to issuers, underwriters, and other offering participants conducting registered securities offerings under the Securities Act, but is generally unavailable to blank check companies, penny stock issuers, and shell companies, consistent with the broader 2005 communications reform's determination that these categories of issuer — whose offerings present heightened risk of abuse through informal communications — should not benefit from the more permissive safe harbours that the 2005 reform extended to conventional operating companies. 

The rule's availability is conditioned on the prior filing of a registration statement containing a Section 10 prospectus; an issuer that has not yet filed any registration statement cannot rely on Rule 134 and must instead consider whether Rule 135's narrower notice of proposed offering safe harbour or Rule 163's pre-filing free writing prospectus accommodation for well-known seasoned issuers is available for its communication.

For IPO issuers specifically, Rule 134 may be relied upon before the filing of a price range prospectus, though the rule does require that a price range prospectus accompany or be referenced through the URL mechanism for certain specific statements — most notably any statement of the offering price — reflecting the rule's calibrated approach to distinguishing between content that can be communicated based on the basic preliminary prospectus alone and content that requires the more developed disclosure of a price range prospectus before it may be included in a Rule 134 notice.

Relationship to Related Rules and Regulations

Rule 134 operates as part of an integrated suite of offering communications safe harbours adopted or substantially revised in the 2005 Securities Offering Reform, alongside Rule 135's notice of proposed offerings safe harbour, Rule 137's research report safe harbour for unaffiliated broker-dealers, Rule 138's safe harbour for research reports about securities other than the ones being registered, and Rule 139's safe harbour for research reports about the issuer published in the regular course of business. 

Where Rule 135 permits a narrower category of basic notice even before any registration statement has been filed, Rule 134 permits a broader category of identifying content but only after a registration statement has actually been filed — the two rules together span the complete pre-filing and post-filing communications timeline for basic factual offering announcements.

Rule 134's electronic hyperlink accommodation for prospectus delivery directly parallels the equivalent provisions in Rule 172's prospectus delivery framework and Rule 433's free writing prospectus accompaniment condition, reflecting the Commission's consistent approach across the 2005 reform to accommodating electronic communication through active hyperlinks as the functional equivalent of physical prospectus delivery or accompaniment. 

Rule 134's required cautionary legend parallels the cautionary language required under Rule 430's preliminary prospectus framework, reinforcing the consistent gun-jumping message that registration remains incomplete and no binding sales may occur until effectiveness.

Rule 134's exclusion of registered investment companies other than closed-end funds connects directly to Rule 482, the dedicated advertising rule for registered investment companies, which provides open-end mutual funds with a tailored framework for performance advertising and other promotional communications calibrated to the specific characteristics of continuously offered fund shares — a framework that the Commission determined was more appropriate for mutual fund communications than the tombstone notice format that Rule 134 was originally designed around.

Amendment History and Regulatory Evolution

Rule 134's most consequential modern evolution occurred in the 2005 Securities Offering Reform, which substantially expanded the rule's permitted content categories, eliminated several prior technical requirements, and modernised the rule's prospectus delivery accommodation for the electronic communications environment. 

The 2005 reform's broader philosophy — relaxing the rigid pre-2005 gun-jumping restrictions to accommodate the realities of modern electronic communication while preserving liability standards and core investor protection objectives — is reflected throughout Rule 134's current framework, particularly in the hyperlink-based prospectus accommodation that allows electronic Rule 134 notices to satisfy the prospectus accompaniment requirement without requiring physical attachment or separate transmission of the full prospectus.

The 2011 and 2020 amendments made further harmonising adjustments to Rule 134 in connection with broader regulatory developments, including the Commission's Exempt Offering Framework rulemaking, which sought to create greater consistency across the patchwork of exemptive and communications rules that had developed incrementally across the Securities Act's regulatory history. 

No substantive amendments to Rule 134's core framework have been adopted since June 2020, and no pending rulemaking proposes changes through June 2026.

Enforcement Context and SEC Action Patterns

Rule 134 enforcement typically arises in the context of communications that exceed the rule's narrow permitted content categories — cases where issuers or underwriters have included promotional or persuasive content, such as photographs, performance projections, or characterisations of the offering's merits, that fall outside the rule's enumerated categories of basic identifying information, thereby losing the rule's exclusion and exposing the communication to characterisation as an illegal prospectus or an unauthorised free writing prospectus subject to Rule 164 and Rule 433's conditions. 

The Division of Corporation Finance's comment letter practice has periodically addressed Rule 134 compliance questions in the context of registration statement reviews, particularly where issuers have included state law suitability statements or other content whose permissibility under Rule 134's enumerated categories required case-specific analysis.

The Commission has historically addressed Rule 134 compliance questions through staff interpretive guidance and no-action correspondence rather than through extensive formal enforcement activity, reflecting the rule's narrow and well-defined scope and the relatively limited universe of content that issuers and underwriters typically seek to include in tombstone-style notices.

Examination Relevance and Key Takeaways

Rule 134 is examined at the Series 7 and Series 65 levels as the principal safe harbour governing tombstone advertisements and basic post-filing offering announcements. Candidates should understand that Rule 134 is available only after a registration statement containing a Section 10 prospectus has been filed — distinguishing it from Rule 135's pre-filing notice safe harbour — and that the rule's permitted content is limited to enumerated categories of basic factual and identifying information about the offering, excluding persuasive or promotional content. 

The rule's required cautionary legend — confirming that the registration statement has been filed but is not yet effective and that no sales or offers to buy may be accepted before effectiveness — is a consistently examined practical detail.

The exclusion of registered open-end investment companies from Rule 134's availability, and the corresponding reliance on Rule 482 for mutual fund advertising, is a relevant examination distinction at the Series 65 level for candidates working with investment company clients.

The key points to retain are these. Rule 134 excludes limited written communications relating to a registered offering from the statutory definition of prospectus, provided the communication is limited to enumerated categories of basic identifying information and is published only after a registration statement containing a Section 10 prospectus has been filed. 

The rule's traditional application — the tombstone advertisement — permits identification of the issuer, the securities offered, the underwriters, and the offering's general timing without that notice itself becoming subject to Section 10's full prospectus content requirements. Notices including pricing information must be accompanied or preceded by a Section 10 prospectus, which in electronic communications may be satisfied through an active hyperlink rather than physical attachment — a non-hyperlinked URL reference does not satisfy this requirement. Registered open-end investment companies other than closed-end funds are excluded from Rule 134's availability and instead rely on Rule 482's dedicated advertising framework. Rule 134 was last amended June 1, 2020 and no further amendments are pending through June 2026.
