SEC Rule 145

The rule's resale provisions, governing the circumstances in which affiliates of a target company who receive securities in a Rule 145 transaction may be deemed underwriters subject to resale restrictions, were comprehensively revised in 2007 to eliminate the presumptive underwriter status that had historically applied to target company affiliates, except in the narrow circumstance where the transaction involves a shell company.

Overview and Regulatory Purpose

Corporate reorganisation transactions — mergers, consolidations, and similar combinations — present a structural challenge to the Securities Act's registration framework that is distinct from the challenge presented by conventional securities offerings. 

In a conventional offering, an issuer sells securities to investors in exchange for cash, and the transaction's character as an offer or sale subject to Section 5's registration requirement is straightforward. In a merger or reorganisation, however, security holders of the target company are not purchasing securities in the conventional sense — they are voting on, or otherwise consenting to, a transaction in which their existing securities will be exchanged for securities of the acquiring company, frequently without any cash changing hands between the security holders and the issuer of the new securities.

Prior to Rule 145's adoption, the Commission's regulatory approach to this challenge rested on the so-called no-sale theory embodied in former Rule 133, under which a vote by security holders to approve a merger, consolidation, or similar reorganisation was deemed not to constitute a sale of securities for Securities Act purposes — the theory being that a corporate vote approving a fundamental change is a corporate governance act rather than an individual investment decision, and that the resulting exchange of securities therefore did not require registration.

Rule 145 rejected this no-sale theory, embodying the Commission's determination that it was no longer consistent with the statutory purposes of the Act.

The rule's underlying analytical insight — articulated in the rule's adopting release and consistently applied since — is that when security holders are required to elect, on the basis of what is in substance a new investment decision, whether to accept a new or different security in exchange for their existing security, that election constitutes precisely the kind of investment decision that the Securities Act's disclosure-based registration framework is designed to inform. 

A shareholder voting to approve a merger in which their shares of Company A will be exchanged for shares of Company B is making a fundamentally different investment decision than a shareholder voting on an ordinary corporate governance matter, such as the election of directors, and that different and more consequential decision warrants the protection of registered disclosure.

Statutory Authority and Rulemaking History

Rule 145 derives its statutory authority from Sections 2(a)(3) and 19(a) of the Securities Act of 1933. Section 2(a)(3) provides the statutory definitions of offer to sell, offer for sale, and sale, the terms from which Rule 145's coverage of reorganisation transactions directly operates; Section 19(a) provides the Commission's general rulemaking authority to define terms and prescribe implementing rules.

Rule 145 was adopted to replace the no-sale approach of former Rule 133, fundamentally reorienting the Commission's regulatory treatment of merger, consolidation, reclassification, and asset transfer transactions structured as securities exchanges. 

The rule's adopting release explicitly articulated the new investment decision theory that continues to govern the rule's application — the principle that an offer or sale occurs whenever security holders must make a new investment decision about whether to accept new or different securities, regardless of whether that decision is formally structured as a corporate vote rather than an individual purchase transaction.

The most significant subsequent amendment to Rule 145 was adopted December 6, 2007 — Securities Act Release No. 33-8869, published at 72 FR 71570, effective February 15, 2008 — as part of the Commission's broader revision of Rule 144's resale framework. Prior to this amendment, Rule 145(c) presumed that any party to a reclassification, merger, or asset transfer transaction other than the issuer — and any affiliate of such party — was an underwriter for purposes of any subsequent public sale of the securities received in the transaction, a presumption that imposed significant resale restrictions on target company affiliates regardless of the specific characteristics of the transaction or the resulting combined company. 

The 2007 amendment eliminated this presumptive underwriter provision except where the transaction involves a shell company, reflecting the Commission's determination that the heightened underwriter presumption was no longer warranted for the broad universe of conventional merger and acquisition transactions but remained appropriate for the heightened fraud risk presented by shell company combinations. 

The eCFR confirms December 6, 2007 as the date of Rule 145's most recent substantive amendment, with no further changes through June 2026.

Key Provisions and Operative Requirements

Rule 145(a) establishes the foundational coverage of the rule across three categories of reorganisation transaction. First, reclassifications of securities — other than a stock split, reverse stock split, or change in par value — that involve the substitution of a security for another security of the same issuer. 

Second, mergers or consolidations in which securities of a corporation or other person are, pursuant to statutory provisions or contractual provisions governing the merger or consolidation, exchanged for securities of any other person. 

Third, transfers of assets of a corporation or other person to another person in consideration of the issuance of securities of such other person or its affiliate, where the transfer is made pursuant to a plan or arrangement for distribution of the securities to the security holders of the corporation or person transferring the assets.

For each of these three transaction categories, Rule 145 establishes that an offer, offer to sell, offer for sale, or sale shall be deemed to occur when there is submitted to security holders a plan or agreement pursuant to which the holders are required to elect, on the basis of what is in substance a new investment decision, whether to accept a new or different security in exchange for their existing security. 

This new investment decision standard is the rule's central analytical principle, and its application has generated substantial interpretive guidance over the decades since the rule's adoption regarding what constitutes a transaction sufficiently transformative to require security holders to make a genuinely new investment decision, as distinguished from transactions — such as a simple stock split or a change in par value that does not alter the fundamental character of the security holder's investment — that fall outside the rule's coverage.

Rule 145(c) establishes the presumptive underwriter provision in its current, post-2007 form, applicable only where shell companies are involved. For purposes of Rule 145, if any party to a Rule 145 transaction is a shell company — other than a business combination related shell company, as those terms are defined in Rule 405 — any party to that transaction other than the issuer, or any person who is an affiliate of such party at the time the transaction is submitted for vote or consent, who publicly offers or sells securities of the issuer acquired in connection with the transaction, shall be deemed to be engaged in a distribution and therefore to be an underwriter within the meaning of Section 2(a)(11) of the Act. 

This narrowed presumptive underwriter provision reflects the Commission's calibrated post-2007 approach: ordinary merger and acquisition transactions no longer trigger automatic underwriter status for target company affiliates, but shell company combinations — historically associated with a heightened risk of fraudulent securities distributions disguised as legitimate reorganisations — continue to warrant the heightened scrutiny and resale restrictions that underwriter status entails.

Rule 145(d) establishes the resale provisions available to persons and parties deemed underwriters under Rule 145(c). Notwithstanding the underwriter presumption, a person or party so specified shall not be deemed to be engaged in a distribution, and therefore not an underwriter, of securities acquired in a Rule 145 transaction that was registered under the Act, if the issuer has met the current public information and reporting requirements applicable under Rule 144(i)(2) — the heightened current information conditions specifically applicable to former shell companies — and the securities are sold in accordance with the manner of sale, volume limitation, and notice requirements of Rule 144's paragraphs (c), (e), (f), and (g), with at least 90 days having elapsed since the securities were acquired from the issuer in the transaction. 

Alternatively, a person or party deemed an underwriter under Rule 145(c) may resell without these Rule 144 conditions if that person or party is not, and has not been for at least three months, an affiliate of the issuer, and at least six months — determined in accordance with Rule 144(d) — have elapsed since the securities were acquired from the issuer in the Rule 145 transaction. 

This dual resale pathway structure directly parallels Rule 144's own affiliate and non-affiliate resale framework, ensuring that the resale conditions applicable to deemed underwriters under Rule 145(d) are conceptually and procedurally consistent with the broader restricted securities resale framework that Rule 144 establishes.

Scope of Application

Rule 145 applies to reclassifications, mergers, consolidations, and asset transfers in which security holders are required to make a new investment decision about exchanging their existing securities for new or different securities, encompassing the broad universe of corporate combination transactions structured as securities exchanges. 

The rule does not apply to transactions falling outside its enumerated categories — stock splits, reverse stock splits, and changes in par value are specifically excluded from the reclassification category, reflecting the Commission's recognition that these transactions, while technically altering the form of a security holder's investment, do not present a genuinely new investment decision in the manner that a merger or asset-for-securities exchange does.

The presumptive underwriter provision of Rule 145(c), and the corresponding resale provisions of Rule 145(d), apply specifically and exclusively to shell company transactions following the 2007 amendments, with business combination related shell companies — as defined in Rule 405 — specifically excluded from the shell company category that triggers the presumptive underwriter analysis. 

This exclusion ensures that special purpose acquisition company structures specifically designed to facilitate legitimate business combinations are not automatically subjected to the heightened underwriter presumption that the rule reserves for shell companies generally, recognising the distinct regulatory treatment that business combination related shell companies receive throughout the Securities Act's communications and registration framework.

Relationship to Related Rules and Regulations

Rule 145's resale provisions under Rule 145(d) are directly and comprehensively integrated with Rule 144's restricted securities resale framework. 

The current public information requirement that Rule 145(d) incorporates by reference to Rule 144(i)(2), and the manner of sale, volume limitation, and notice conditions incorporated from Rule 144(c), (e), (f), and (g), mean that a person deemed an underwriter under Rule 145(c) faces resale conditions that are functionally identical to those applicable to an ordinary Rule 144 affiliate, differing primarily in the specific holding period and current information conditions calibrated to the shell company context that triggered the underwriter presumption in the first place.

Rule 145's interaction with Rule 425's business combination communications framework is significant in the practical conduct of merger transactions. Rule 425 governs the filing requirements applicable to written communications relating to business combination transactions, and a transaction subject to Rule 145's registration requirement will typically also implicate Rule 425's communications filing obligations during the period leading up to the shareholder vote or consent that triggers the new investment decision Rule 145 identifies. Rule 145a — a companion provision specifically addressing business combinations with reporting shell companies — provides additional and more detailed guidance for the specific scenario in which the heightened shell company analysis under Rule 145(c) and (d) becomes operative.

Rule 145's foundational new investment decision theory also connects to the broader proxy solicitation framework of Regulation 14A, since the security holder vote that Rule 145 identifies as triggering the offer or sale analysis is typically conducted through a proxy solicitation subject to Rule 14a-3's proxy statement delivery requirements and Rule 14a-9's antifraud standard, requiring that the merger or reorganisation proxy statement satisfy both the Securities Act's registration disclosure requirements that Rule 145 triggers and the Exchange Act's proxy solicitation disclosure and antifraud requirements simultaneously.

Amendment History and Regulatory Evolution

Rule 145's most consequential amendment was the December 2007 revision that eliminated the presumptive underwriter provision for non-shell company transactions, fundamentally reorienting the rule's resale framework from a broad default presumption applicable to virtually all merger and acquisition target company affiliates toward a narrowly targeted presumption applicable only to the heightened risk category of shell company combinations. 

This amendment reflected the Commission's broader 2007 modernisation of the Rule 144 restricted securities framework, which simultaneously shortened Rule 144's general holding periods and streamlined its resale conditions for the broad population of issuers and security holders subject to its requirements, while specifically preserving and even strengthening certain conditions applicable to the shell company context where fraud risk has historically been concentrated.

The rule's earlier amendments across 1984, 1985, 1990, 1997, and 1999 reflected incremental refinements to the rule's coverage and application as merger and acquisition practice evolved, without altering the rule's fundamental new investment decision analytical framework, which has remained the stable conceptual foundation of Rule 145's coverage determination since the rule's original adoption.

Enforcement Context and SEC Action Patterns

Rule 145 enforcement and interpretive activity has historically concentrated on two recurring questions. The first involves the precise boundary of the new investment decision standard — circumstances in which the Commission staff has been called upon to determine whether a particular reclassification or corporate restructuring transaction genuinely requires security holders to make a new investment decision triggering Rule 145's registration requirement, as distinguished from transactions that merely adjust the form of an existing security without presenting the security holder with a genuinely new investment choice.

The second recurring area of interpretive activity, reflected extensively in the Division of Corporation Finance's Compliance and Disclosure Interpretations addressing Rule 145, involves the application of the resale provisions of Rule 145(d) to specific factual circumstances — including questions about partial public and partial private resales by affiliates deemed underwriters under Rule 145(c), the treatment of securities conversions following receipt in a Rule 145 transaction, and the interaction between Rule 145(d)'s resale conditions and the financial statement filing requirements applicable to acquired companies under Form 8-K.

Examination Relevance and Key Takeaways

Rule 145 is examined at the Series 7 and Series 65 levels in the context of corporate reorganisation transactions and their treatment under the Securities Act's registration framework. Candidates should understand the rule's new investment decision standard as the central analytical principle determining whether a reclassification, merger, consolidation, or asset transfer requires Securities Act registration, and the rule's rejection of the prior no-sale theory that had treated corporate reorganisation votes as outside the scope of the Act's registration requirements.

The narrowed scope of Rule 145(c)'s presumptive underwriter provision — now applicable only to shell company transactions following the 2007 amendments — and the corresponding resale conditions of Rule 145(d), which mirror Rule 144's affiliate and non-affiliate resale framework, are consistently examined concepts at the Series 65 level in the context of merger and acquisition securities law practice.

The key points to retain are these. Rule 145 deems an offer, offer to sell, offer for sale, or sale to occur whenever security holders are required to make a new investment decision about whether to accept a new or different security in exchange for their existing security in connection with a reclassification, merger or consolidation, or transfer of assets — rejecting the prior no-sale theory that had exempted such transactions from registration. Stock splits, reverse stock splits, and changes in par value are excluded from the reclassification category. 

Following the 2007 amendment, the presumptive underwriter provision of Rule 145(c) applies only where the transaction involves a shell company other than a business combination related shell company; non-shell company target affiliates are no longer automatically deemed underwriters. 

Persons deemed underwriters under Rule 145(c) may resell under conditions mirroring Rule 144's affiliate and non-affiliate frameworks, including the current public information requirements of Rule 144(i)(2) for former shell companies. Rule 145 connects directly to the proxy solicitation framework of Regulation 14A and the business combination communications requirements of Rule 425. Rule 145 was last amended December 6, 2007, effective February 15, 2008, and no further amendments are pending through June 2026.
