A sponsor's Rule 506(c) raise for one building is still collecting its last commitments when a second property goes under contract. The sponsor wants to offer the new deal quietly under Rule 506(b) to investors it knows, some of whom have just seen the first deal advertised online. Whether the two raises stand apart is a question of Rule 152 integration, the SEC's test for when separate offerings must be treated as one. The answer turns less on labels than on dates and records the sponsor may not have kept.
Rule 152 took its current form in Securities Act Release No. 10884, adopted on November 2, 2020 and effective March 15, 2021. SEC staff added three interpretations of it to the Securities Act compliance and disclosure interpretations on January 23, 2026. A sponsor running raises close together should apply the rule deliberately, through the 30 calendar day safe harbor or the general principle, and document how each 506(b) purchaser was reached. Integration can turn two raises that each comply into one that fails. The guide to accredited investor verification under 506(c) covers the verification side of the same decisions.
What Rule 152 Integration Tests
Integration exists because one financing can be cut into pieces that each look exempt. The 2020 release calls this "artificially dividing a single offering into multiple offerings" to avoid registration. Before 2021, offerings within six months of each other were weighed against five factors under Rule 502(a). Rule 152 replaced that test with a general principle. Offerings are not integrated if the issuer can establish that each one is registered or has its own exemption.
The text of Rule 152 opens with a limit. Nothing in it protects transactions that comply on paper but form part of a plan to evade registration. The rule also speaks of "the issuer" throughout, while most syndications put each deal in its own LLC. A sponsor that applies the rule to every pair of overlapping raises, whatever the entity, keeps the records it would need if the two were ever viewed together.
The Four Safe Harbors in Rule 152(b)
If a safe harbor applies, no analysis under the general principle is needed. Rule 152(b) lists four, none of them exclusive.
- Rule 152(b)(1), the 30 day safe harbor. 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, subject to a proviso for offerings that bar general solicitation.
- Rule 152(b)(2). Offers and sales under Rule 701, under an employee benefit plan, or in compliance with Regulation S are not integrated with other offerings.
- Rule 152(b)(3). A registered offering is not integrated with certain earlier offerings that have ended.
- Rule 152(b)(4). Offers and sales under an exemption that permits general solicitation, such as Rule 506(c), are not integrated with any offering that ended before them.
Two of the four do most of the work for a sponsor. Under Rule 152(b)(4), a 506(c) raise that follows a finished 506(b) raise stands apart, whatever the gap. The Regulation S safe harbor lets an offshore track run beside a U.S. raise, as the Regulation S guide for real estate sponsors explains. Rule 500(g) adds that Regulation S purchasers do not count toward Regulation D purchaser limits.
When an Offering Starts and Ends for the 30 Day Count
The 30 day safe harbor depends on two dates, and the rule ties neither to a single event. A Regulation D offering commences on the date the issuer first made an offer in reliance on the exemption. It terminates on the later of a binding commitment to sell all the securities, subject only to conditions outside the investor's control, and the date the issuer and its agents stop making offers.
These are factors rather than definitions, so the dates rest on facts the sponsor can show. A deal page that still accepts commitments suggests the first offering has not ended. The release also bars using a 506(c) general solicitation to find investors for a 506(b) offering. If an issuer does, the 506(b) offering may be deemed to have commenced when the solicitation began. The count runs from what the sponsor did, not what its calendar intended.
Running 506(b) and 506(c) Raises Close Together
When raises overlap or sit less than 30 days apart, the general principle decides. For an offering that bars general solicitation, Rule 152(a)(1) requires a reasonable belief about each purchaser. Either the issuer did not solicit that purchaser through general solicitation, or it established a substantive relationship with the purchaser before the 506(b) offering commenced. On that basis, the release says, concurrent 506(b) and 506(c) offerings are possible if each exemption's other conditions are met.
The release defines a substantive relationship as one in which the issuer has enough information to evaluate, and does evaluate, an offeree's financial circumstances and sophistication. Existing and prior investors can qualify, as can investors in earlier deals of the issuer's management, while a checked box alone does not. Staff applied that standard to a move from 506(c) to 506(b) in an interpretation discussed in how general solicitation rules shape a real estate raise. The release also warns that advertising which mentions the material terms of a 506(b) offering may be an offer in it.
Two further limits catch sponsors who rely on time alone. Under the proviso to the 30 day safe harbor, a 506(b) offering that follows an advertised offering must still satisfy Rule 152(a)(1). Distance in time does not clear a purchaser reached through advertising. And Rule 506(b) caps purchasers who are not accredited at 35 across all of the issuer's 506(b) offerings in any 90 calendar day period. The SEC added that cap in 2020 so the shorter safe harbor could not support a monthly series of 506(b) raises.
What Happens When Two Raises Are Integrated
Integrated raises are one offering, which must fit a single exemption. A combined offering that used advertising cannot rely on Rule 506(b), and it can rely on Rule 506(c) only if every purchaser was accredited and verified through reasonable steps. Rule 506(b) does not require that verification, so purchasers in a quiet raise may lack it, and then neither exemption holds.
Sales without an exemption breach the registration requirement in Section 5 of the Securities Act. Section 12(a)(1) then lets each purchaser sue to recover the price paid, with interest, less any income received, upon tender of the security. That exposure can surface long after the capital has gone into the property.
What Sponsors Can Do Before the Next Raise Opens
The steps work best in order, before the new deal's first offer, and each leaves a dated record. The advertised raise has its own setup, which the 506(c) capital raise checklist sets out.
- Choose the exemption for the next deal and record the date of its first offer.
- Record the date the current raise stopped offering, and check whether more than 30 calendar days separate the two.
- If the gap is shorter, or the earlier raise advertised, list each planned 506(b) purchaser with the date and basis of a relationship formed before the 506(b) offering began.
- Keep the new deal's terms out of public marketing for the open 506(c) raise, and count purchasers who are not accredited across every 506(b) offering in the trailing 90 calendar days.
Raveum gives U.S. real estate sponsors a white label platform to run their raises, either on their own with Tier 1 Self-Managed or with Raveum's operations team on Tier 2 Assisted, where the sponsor's own counsel approves every document the team drafts. On both tiers the sponsor sets Rule 506(b) or Rule 506(c) for each deal. Investor communications, the dashboard, the audit log and acceptance records keep a dated trail of who was invited to which deal and when. See how the Raveum Sponsor Program works.
Two Raises and One Record
The sponsor with a 506(c) raise still open has two clean routes to the next deal. It can wait until the first offering has stopped and more than 30 calendar days have passed. Any 506(b) purchaser reached by the advertising still needs an earlier relationship. Or it can run the second raise now under the general principle, with a dated record of how it knew each 506(b) purchaser before that offering began. Both routes rest on the same evidence, the dates of offers and the history of each relationship. The guide to accredited investor verification under 506(c) shows how that record fits the wider raise.
Frequently Asked Questions
What Is Rule 152 Integration
Rule 152 integration is the SEC's test for whether two or more offerings by an issuer should be treated as one. Under the general principle, offerings are not integrated if the issuer can show each one is registered or has its own exemption. Four safe harbors in Rule 152(b) remove the need for that analysis, and none protects a plan or scheme to evade registration.
How Does the 30 Day Integration Safe Harbor Work
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. The count runs from the first offer of one offering and from the date the other stopped offering or had binding commitments for all its securities. A 506(b) offering that follows an advertised offering must still meet the general principle.
Can a Sponsor Run 506(b) and 506(c) Offerings at the Same Time
Yes, under the general principle, if each exemption's conditions are met. For the 506(b) offering, the sponsor needs a reasonable belief that each purchaser was either not solicited through general solicitation or had a substantive relationship with the sponsor before the 506(b) offering began. Advertising for the 506(c) deal that describes the 506(b) deal's terms may count as an offer in it.
When Does an Offering Begin and End Under Rule 152
A Regulation D offering begins on the date of the issuer's first offer under the exemption. It ends on the later of two dates, a binding commitment to sell all the securities subject only to conditions outside the investor's control, or the day the issuer and its agents stop making offers. These are factors, so the facts behind each date should be recorded.
Does a Regulation S Offering Integrate With a Regulation D Offering
No. Under Rule 152(b)(2), offers and sales made in compliance with Regulation S are not integrated with other offerings, and Rule 500(g) adds that Regulation S purchasers are not counted toward Regulation D purchaser limits. The safe harbor covers integration only. Each track must still meet its own conditions, including the Regulation S bar on directed selling efforts in the United States.
What Happens If Two Private Offerings Are Integrated
The two raises are treated as one offering, which must meet a single exemption. If one raise advertised and the other sold to purchasers who were never verified as accredited, neither Rule 506(b) nor Rule 506(c) may fit. Sales without an exemption breach Section 5 of the Securities Act, and purchasers can sue to recover what they paid, with interest, less income received.
