The regulatory landscape for Regulation D private offerings has shifted significantly over the past 18 months. In a span of just a few weeks in late 2024, the Securities and Exchange Commission (SEC) announced a series of settled enforcement actions that sent shockwaves through the private placement community — not because they involved outright fraud, but because sponsors were penalized solely for missing a paperwork deadline. For the first time in the agency's history, the SEC imposed monetary sanctions and stripped issuers of future Regulation D privileges simply for failing to timely file a Form D.

For Rule 506(c) sponsors who rely on general solicitation and advertising to attract accredited investors, the stakes of regulatory non-compliance have never been higher. A single enforcement action can do more than result in a fine — it can trigger disqualification from the Regulation D exemption entirely, effectively ending your ability to raise private capital. At the same time, 2025 also brought a landmark SEC no-action letter that meaningfully eased the investor verification burden, opening the door for more sponsors to confidently use general solicitation.

This article examines the most significant Regulation D enforcement actions of 2024–2025, analyzes the SEC's shifting priorities under Chairman Paul Atkins, unpacks the March 2025 verification safe harbor, and provides actionable compliance guidance for every 506(c) issuer conducting general solicitation today.

The December 2024 Form D Enforcement Actions: A Historic First

On December 20, 2024, the SEC announced something that had never happened before in the history of Regulation D: settled enforcement charges against three entities solely for failing to timely file Forms D in connection with their private offerings. The three respondents — one registered investment adviser and two private operating companies — were not charged with fraud, misrepresentation, or any other substantive violation. Their sole offense was missing the 15-day filing deadline required under Rule 503 of Regulation D.

The financial consequences were real and significant. According to Foley Hoag's analysis of the actions, the settling parties were fined between $60,000 and $195,000 each. But the monetary penalties were only part of the story.

The Disqualification Consequence

Far more consequential than the fines was the structural penalty embedded in these settlements. As documented by the Securities Law Blog's January 2025 analysis, each of the three companies was prohibited from relying on Regulation D in the future unless specifically granted a waiver by the SEC. This means a late Form D filing — a compliance failure that many sponsors historically treated as an administrative afterthought — can permanently disqualify an issuer from ever using the Regulation D exemption again without special SEC approval.

For active private fund managers and real estate syndicators who depend on Regulation D to raise capital deal after deal, this is an existential risk. A single missed deadline doesn't just result in a fine; it can end your capital-raising career.

Why This Matters Especially for 506(c) Issuers

Legal analysis from Foley & Lardner highlighted a critical nuance that every 506(c) sponsor must understand: prior to these enforcement actions, the private equity industry widely assumed that the SEC would not bring standalone actions for Form D filing failures alone. That assumption is now definitively wrong. Furthermore, Foley & Lardner noted that the SEC's announcement specifically flagged offerings where issuers may have engaged in general solicitation — the defining feature of 506(c) offerings — as a particular area of concern.

The message is unambiguous: if you are advertising your offering to the public under Rule 506(c), you are subject to heightened scrutiny, and your Form D obligations are not optional.

The Shifting SEC Enforcement Landscape Under Chairman Atkins

While the December 2024 Form D actions came under outgoing Chairman Gary Gensler's watch, the broader 2025 enforcement environment was shaped by a significant leadership transition at the SEC. Understanding who is now running the agency — and what they prioritize — is essential context for every 506(c) sponsor.

From Gensler to Atkins: A New Enforcement Philosophy

Following the inauguration of President Trump, Acting Chairman Mark Uyeda led the SEC until Paul Atkins was sworn in on April 21, 2025. According to Gibson Dunn's year-end enforcement update, the transition brought sweeping changes. The SEC's total workforce declined by approximately 15% — from roughly 5,000 employees to approximately 4,200 — as of mid-2025. Total monetary settlements also declined by 45% to $808 million, and new enforcement actions fell to 313, the lowest in a decade and down 27% from FY 2024 levels.

However, sponsors should not interpret fewer enforcement actions as less regulatory risk. Paul Weiss's 2025 enforcement year-in-review notes that the new administration has demonstrated an intent to maintain — and in some respects intensify — enforcement in traditional domains such as fraud involving retail investor harm. Chairman Atkins has stated publicly that investor protection remains the cornerstone of the SEC's mission.

The "Bread-and-Butter" Enforcement Focus

The current SEC has made clear that while it is stepping back from novel regulatory theories, it is doubling down on fundamental fraud. Cleary Gottlieb's 2025 year-in-review analysis confirms that offering fraud comprised 27% of all SEC actions brought in FY 2025, up from 22% in FY 2024. This includes Ponzi schemes, misappropriation of investor funds, and false statements in offering materials — all of which are directly relevant to private placement sponsors.

The 2026 SEC examination priorities, released by the Division of Examinations on November 17, 2025, reinforce this focus. According to Crowdfunding Lawyers' analysis of those priorities, examiners will scrutinize investment advisers' fiduciary standards, expense disclosures, and the accuracy of technology claims in marketing materials — including alleged use of artificial intelligence in investment decision-making.

What "Retailization" of Private Markets Means for 506(c) Sponsors

One of the most important regulatory trends identified in the 2026 examination priorities is the acknowledgment that private markets are becoming "retailized." As Crowdfunding Lawyers noted, the SEC recognizes that more individual accredited investors are now participating in syndications than at any previous point in history — and regulators are applying public-market levels of scrutiny to private placement operations as a result. If you are raising capital from individuals via Rule 506(b) or 506(c), you are now operating in a heightened oversight environment.

Notable Offering Fraud Enforcement Cases: Lessons for Legitimate Sponsors

Beyond the Form D filing actions, the SEC brought a series of significant offering fraud cases in 2025 that provide critical lessons for compliant 506(c) sponsors. Understanding what went wrong in these cases — and why — helps legitimate operators identify and avoid practices that trigger regulatory scrutiny.

The Kenneth Mattson Real Estate Fraud Case (May 2025)

On May 22, 2025, the SEC filed charges against Bay Area real estate investor Kenneth Mattson, alleging a Ponzi-like scheme spanning approximately 15 years. According to Holland & Knight's detailed case analysis, Mattson allegedly defrauded approximately 200 investors — many of them elderly, retired church community members — out of at least $46 million. Despite managing approximately 50 legitimate real estate investment partnerships, Mattson allegedly sold fake limited partnership interests that were never officially recorded, commingling funds with legitimate accounts and using investor money to support his lifestyle.

This case exemplifies what the SEC calls "affinity fraud" — schemes that exploit trust within a community group. For legitimate real estate syndicators, this case underscores the absolute importance of maintaining complete and accurate investor records, separate accounts for each offering, and full documentation of partnership interests at the time of sale.

The Commercial Real Estate Internet Funding Fraud (February 2025)

In February 2025, the SEC filed fraud charges against a New York-based commercial real estate firm and its owner for using an internet funding platform to raise over $52 million from over 700 investors by falsely claiming the funds would be used to purchase two specific commercial real estate deals. The funds were instead allegedly misused for unrelated projects, luxury purchases, and personal stock trading. The U.S. Attorney's Office filed parallel criminal charges.

This case is a direct cautionary tale for 506(c) sponsors who use online platforms and digital advertising to raise capital. The SEC's scrutiny of internet-based offerings is acute, and any misrepresentation of how investor funds will be used — even an inadvertent one — can trigger both civil and criminal liability.

The $93 Million Real Estate Development Scheme (April 2025)

In April 2025, the SEC charged the former CFO of a real estate development company for participating in a $93 million fraud scheme involving more than 50 investors and multiple development projects. The alleged misconduct included commingling investor funds and personal misappropriation. The SEC had already charged a separate executive in the same scheme, highlighting how enforcement actions can sweep in multiple parties across an organization.

For fund managers and syndicators, this case illustrates that enforcement liability is not limited to a single individual or the "face" of an offering. Officers, CFOs, and managing partners can all face personal liability when fund management practices are improper — even if they claim ignorance of the broader scheme.

Common Violations Across All Cases

Reviewing these cases collectively, several patterns emerge in what the SEC pursues. According to Syndication Attorneys' analysis of SEC enforcement actions, the most frequently charged provisions include Section 10(b) of the Securities Exchange Act of 1934, Rule 10b-5, and Section 17(a) of the Securities Act of 1933 — all of which prohibit fraudulent conduct, material misstatements, and material omissions in connection with the offer or sale of securities.

2024–2025 Regulation D Enforcement Actions at a Glance

The following table summarizes the key enforcement actions and regulatory developments most relevant to Regulation D and 506(c) sponsors from December 2024 through early 2026.

The March 2025 No-Action Letter: A New Safe Harbor for 506(c) Verification

Amid the enforcement activity, March 2025 brought genuinely positive news for sponsors conducting general solicitation under Rule 506(c). On March 12, 2025, the SEC's Division of Corporation Finance issued a landmark no-action letter that substantially simplified the accredited investor verification requirement — the single greatest compliance burden that had historically discouraged sponsors from using 506(c) over 506(b).

What the No-Action Letter Establishes

The no-action letter, issued in response to a request by law firm Latham & Watkins LLP, established a clear safe harbor for satisfying the "reasonable steps" verification requirement of Rule 506(c). According to Morgan Lewis's analysis, the SEC confirmed that an issuer satisfies the "reasonable steps" requirement when it combines two elements: a minimum investment threshold and a written self-certification from the investor.

Specifically, IQ-EQ's detailed breakdown of the guidance confirmed the following thresholds and conditions:

• Natural persons: A minimum investment commitment of at least $200,000 in cash (or the right to call cash)
• Legal entities: A minimum investment commitment of at least $1,000,000
• Written self-certification: The investor must represent in writing that they are an accredited investor and have not financed their investment through a third party
• No red flags: The issuer must have no actual knowledge that the investor is not accredited

Why This Changes the 506(c) Calculus

Prior to this guidance, the "reasonable steps" verification requirement under Rule 506(c) was widely viewed as onerous and intrusive. Issuers were expected to collect and review financial documentation — tax returns, bank statements, brokerage account records — directly from investors before closing. This created friction in the investment process and led many sponsors to use 506(b) instead, sacrificing the right to advertise in exchange for an easier verification standard.

As Reed Smith's August 2025 client alert put it, this new flexibility removes one of the primary reasons for avoiding public advertising in Regulation D offerings, and the firm predicted that many more private funds and companies will now use public advertising in their Regulation D securities offerings.

For 506(c) sponsors who rely on Facebook and Instagram advertising, email campaigns, websites, or other general solicitation channels, the practical implications are profound: if your minimum investment is set at $200,000 or above for individual investors, you can now satisfy your verification obligation primarily through a self-certification form — without needing to collect sensitive financial documents from every investor.

Important Limitations of the Safe Harbor

Sponsors should be aware that this safe harbor does not eliminate all verification obligations. According to Gibson Dunn's analysis of the no-action letter, the letter makes Rule 506(c) a more attractive option for private fund sponsors, but broadly marketing a private fund continues to present certain challenges that the letter does not address. For example, the safe harbor does not apply if the issuer has reason to believe an investor is not accredited, regardless of the minimum investment amount. Sponsors still need robust processes for identifying and flagging potential red flags in investor representations.

The SEC's 2026 Examination Priorities: What Sponsors Must Prepare For

The Division of Examinations released its Fiscal Year 2026 Examination Priorities on November 17, 2025. This document is required reading for every active 506(c) sponsor, because it tells you exactly where SEC examiners will be looking when they review your operations.

Priority 1: Fiduciary Standards and Conflicts of Interest

The 2026 priorities place particular scrutiny on investment advisers' adherence to fiduciary standards, especially regarding the management of financial conflicts of interest and fee disclosures. Morgan Lewis's November 2025 securities enforcement roundup confirmed that examiners will review investment advice and disclosures for consistency with fiduciary obligations, with special attention to complex and alternative investment products — specifically including private credit and other private funds.

For 506(c) sponsors: ensure your offering documents, investor presentations, and ongoing communications fully disclose all fees, fee structures, and potential conflicts of interest. Do not charge fees based on historical valuations if current market values differ significantly from original purchase prices.

Priority 2: AI and Technology Claims in Marketing

One of the most novel and important 2026 priorities concerns the accuracy of technology and artificial intelligence claims. According to Crowdfunding Lawyers' analysis of the 2026 examination priorities, the SEC is cracking down on issuers who exaggerate their technology capabilities to attract capital — specifically distinguishing between "using AI" and "AI-driven investing." If your marketing materials, pitch deck, or PPM claims you use a proprietary algorithm or machine-learning model to identify investment opportunities, and your actual process is manual, you are potentially violating anti-fraud provisions.

Review every piece of marketing collateral and all investor-facing materials for technology claims. If you use software tools, clearly and accurately describe their actual function. Remove or qualify any language that overstates the role of technology in your investment process.

Priority 3: Asset Valuation Practices

The 2026 priorities also target the accuracy of asset valuations within fund portfolios — a particularly sensitive issue for real estate sponsors operating in a market where valuations have shifted substantially since 2021. Holding assets at 2021 appraised values when current market values have declined significantly can be considered materially misleading to investors, especially when management fees are calculated on those valuations.

Practical steps recommended by compliance professionals include implementing quarterly internal valuation committee meetings, documenting the inputs for each asset (current cap rates, discount rates, comparable sales), and ensuring that fee calculations reflect current fair market value where required by offering documents.

Priority 4: Expense Allocation Transparency

The SEC will closely examine how fund managers allocate expenses between the fund and the manager. This includes scrutiny of reimbursable expenses — a common area where sponsors inadvertently charge items to the fund that their offering documents do not authorize. Sponsors should audit their expense allocation records before the 2026 examination cycle and ensure that every reimbursed expense is clearly authorized by the fund's operating agreement or PPM.

A Practical Compliance Action Plan for Active 506(c) Sponsors

Based on the enforcement actions and regulatory guidance reviewed in this article, here is a concrete compliance action plan for every active 506(c) sponsor conducting general solicitation in 2025 and 2026.

Step 1: Audit Your Form D Filing History

Review every active and recently closed offering. For each offering, confirm that a Form D was filed with the SEC within 15 days of the first sale of securities. If amendments are required (for changes to the offering amount, date of first sale, or other material information), verify those amendments have been filed. The CrowdCheck analysis of the December 2024 enforcement actions confirms that the SEC relies on Form D filings to assess the scope of the Regulation D market and to monitor compliance — these filings are actively reviewed, not simply collected and archived.

Step 2: Implement a Verification Protocol Aligned with the March 2025 Safe Harbor

If your offering has a minimum investment of $200,000 or more for natural persons (or $1,000,000 for entities), update your subscription documents to include the written self-certification required under the March 2025 no-action letter framework. The certification should state that the investor is an accredited investor and has not financed their investment through a third party. Train your investor relations team to identify and escalate any red flags that might suggest an investor does not meet the accredited investor standard despite meeting the minimum investment threshold.

Step 3: Conduct a Marketing Materials Compliance Review

Pull all current marketing materials — including digital ads, landing pages, email sequences, pitch decks, and PPMs — and review them against the following checklist:

• Do any materials contain guaranteed return promises or projections presented without appropriate risk disclosures?
• Are all technology and AI capability claims accurate and verifiable?
• Are all fees, fee structures, and conflicts of interest fully and fairly disclosed?
• Does the description of fund use of proceeds match the actual intended use of investor capital?
• Are all claims about the sponsor's track record, credentials, and assets under management accurate?

Step 4: Establish Segregated Accounts and Investor Record Systems

Enforcement cases like the Mattson matter and the commercial real estate fraud action make clear that fund commingling and inadequate investor record-keeping are high-priority enforcement targets. Every 506(c) sponsor should maintain separate bank accounts for each offering, implement a CRM or investor management platform that documents every investor's interest at the time of sale, and ensure that distributions and capital calls are processed from the correct account for each fund.

Step 5: Institute Quarterly Valuation Reviews

For real estate and private equity sponsors, establish a formal valuation committee process that meets at least quarterly. Document the inputs and methodology used for each asset valuation, and ensure that any fee calculations based on asset values reflect current fair market value where required by your offering documents.

Step 6: Perform "Bad Actor" Disqualification Checks

Under Rule 506(d) of Regulation D, the 506(c) exemption is unavailable to any issuer if a "covered person" — including managing members, executive officers, directors, general partners, and 20% or greater owners — has been subject to certain disqualifying events, such as criminal convictions, SEC orders, or regulatory sanctions. Syndication Attorneys note that a single enforcement action against any covered person can permanently shut down an issuer's ability to raise private money. Run background checks on all covered persons before every new offering and document those checks.
