Integration, State Blue-Sky Law and Cross-Border Tranches

Rule 152, rebuilt by the SEC's November 2, 2020 amendments, decides when separate offerings are treated as one, using a general facts-and-circumstances principle plus four non-exclusive safe harbors, including a 30-calendar-day separation ^[1][2]. Federal law since the National Securities Markets Improvement Act of 1996 preempts state registration of Rule 506 offerings but lets states require notice filings, fees and consent to service, and keeps their antifraud authority ^[4][13][14]. Regulation S covers offers and sales outside the United States, and Rule 144A lets buyers resell to qualified institutional buyers, which is how many cross-border and institutional tranches are built ^[8][11].

Integration: when two offerings become one

If a company sells securities under different pathways in parallel or close in time, the question is whether the offerings should be viewed as one integrated offering, and if they are, the combined offering may fail the conditions of each exemption ^[3]. The SEC's November 2, 2020 amendments replaced older tests with one framework: a general principle that looks to the facts and circumstances, plus four non-exclusive safe harbors ^[2]. Under the general principle, offerings will not be integrated if the issuer can establish that each one either complies with registration or has its own available exemption ^[1].

• For an offering that prohibits general solicitation, the issuer must reasonably believe that each purchaser was either not solicited through general solicitation or had a substantive relationship with the issuer before that offering began ^[1].
• For two concurrent offerings that both permit general solicitation, materials for one that mention the material terms of the other may be an offer in the other offering and must meet its rules, including legends ^[1].

The four safe harbors

• Thirty days: an offering made more than 30 calendar days before another begins, or more than 30 calendar days after another ends, is not integrated with it, but a no-solicitation offering that follows a general-solicitation offering must still meet the reasonable-belief test above ^[1].
• Rule 701 and Regulation S: compensatory offerings under an employee benefit plan and offshore offerings under Regulation S are not integrated with other offerings ^[1].
• Registered offerings: a registered offering is not integrated with an earlier completed offering that barred general solicitation, one that solicited only qualified institutional buyers and institutional accredited investors, or one that ended more than 30 calendar days before ^[1].
• General solicitation after completion: an offering that permits general solicitation is not integrated with any offering that has already terminated or completed ^[1].

Timing definitions matter. An offering commences with the first offer by the issuer or its agents, and a Section 4(a)(2) or Regulation D offering terminates on the later of the date the issuer has binding commitments for all securities to be sold or the date it stops making offers ^[1].

Worked example: a SAFE round and a crowdfunding campaign

A startup is closing a $2 million Rule 506(b) SAFE round with angels it knows and wants to launch a Regulation Crowdfunding campaign promoted on social media. If it waits until the SAFE round has terminated, the crowdfunding offering, which permits general solicitation, falls in the fourth safe harbor ^[1]. If instead it starts promoting the campaign while the SAFE round is still open, it must work from the general principle: for each SAFE investor, it needs a reasonable belief that the investor was not found through the social media campaign or had a substantive relationship with the company before the SAFE round began ^[1]. A short calendar gap and a clean list of who was contacted, and when, is usually the cheapest protection.

State blue-sky law and NSMIA preemption

The National Securities Markets Improvement Act of 1996, enacted October 11, 1996, reshaped the federal and state split ^[13]. Section 18 of the Securities Act, as amended, bars state registration or qualification requirements for 'covered securities' ^[4]. Securities sold under Commission rules issued under Section 4(a)(2) are covered, but states may impose notice filings substantially similar to those in effect on September 1, 1996 ^[4]. Rule 506 is such a rule, so Rule 506(b) and 506(c) offerings are preempted from state registration and qualification, although states may still require notice filings and collect fees ^[14]. Crowdfunding securities under Section 4(a)(6) and resales under Section 4(a)(7) are also covered, as are Regulation A securities offered or sold to a 'qualified purchaser' as the SEC defines that term ^[4]. In practice, Tier 2 offerings need no state registration, while Tier 1 offerings must register or find a state exemption in each state where they are sold ^[7].

Preemption is not a free pass. States may still require copies of documents filed with the SEC, reports of sales in the state, a consent to service of process and fees, and they keep authority to investigate and bring enforcement actions for fraud or deceit ^[4]. NASAA's Electronic Filing Depository lets filers submit Rule 506 notice filings and fees to participating state regulators electronically ^[5]. Rule 504 sits outside this preemption: it must satisfy state registration or a state exemption, and its general-solicitation and resale restrictions fall away only for offerings made under state registration with a disclosure document or under state exemptions that permit general solicitation to accredited investors ^[6].

Regulation S: offshore tranches

For purposes of Section 5, Regulation S treats offers and sales that occur outside the United States as outside the registration requirement ^[8]. The issuer safe harbor requires an offshore transaction and no directed selling efforts in the United States by the issuer, distributors, their affiliates or anyone acting for them ^[9]. Equity of a U.S. issuer that is not an SEC reporting company falls in Category 3, which requires offering restrictions and, during a one-year distribution compliance period (six months for reporting issuers), sales only to non-U.S. persons who certify that status and agree to resell only under Regulation S, registration or an exemption, along with a restrictive legend and an issuer undertaking to refuse non-compliant transfers ^[9]. Debt in Category 3 uses a 40-day period ^[9]. Equity of a U.S. issuer bought under Regulation S is a restricted security under Rule 144 ^[10].

Rule 144A: institutional resales

Rule 144A is a resale safe harbor: a seller other than the issuer who sells only to a qualified institutional buyer, or one it reasonably believes is a QIB, is not treated as an underwriter ^[11]. A QIB is generally an institution that owns and invests on a discretionary basis at least $100 million in securities of unaffiliated issuers, or a registered dealer with at least $10 million ^[11]. The securities cannot be of the same class as exchange-listed securities, the buyer must be told the seller may rely on Rule 144A, and for most non-reporting issuers holders must be able to obtain basic, reasonably current business and financial information ^[11]. Securities acquired under Rule 144A are restricted securities, and an issuer selling to initial purchasers who plan to resell under Rule 144A does not lose its Section 4(a)(2) or Regulation D exemption ^[11]. SEC staff estimate that non-fund issuers raised about $1 trillion through Regulation S and Rule 144A in calendar year 2024 ^[12].
