Private Placement Due Diligence: What FINRA Still Expects in 2026

For all the regulatory changes affecting private placement professionals over the past several years, one thing has remained remarkably consistent: FINRA expects registered representatives to thoroughly understand every private placement they recommend.

Whether you’re raising capital for an operating company, a real estate fund, a venture fund, or another Regulation D offering, FINRA continues to view broker-dealers—and the registered representatives acting through them—as important gatekeepers. Simply relying on an issuer’s management team, outside counsel, or offering documents is not enough.

The good news?

FINRA isn’t asking firms to reinvent their compliance programs. The regulator’s 2026 Annual Regulatory Oversight Report largely reinforces the same principles it outlined in Regulatory Notice 23-08: conduct a reasonable investigation of the issuer and offering, follow a documented due diligence process, appropriately supervise private placement activity, ensure communications with investors are fair and balanced, and comply with applicable FINRA filing requirements.

For experienced investment bankers, much of this will sound familiar. The core expectations haven’t changed—they’ve simply been reaffirmed.

Let’s look at what that means in practice.

FINRA’s Core Areas of Focus

The 2026 Annual Regulatory Oversight Report identifies several recurring examination areas for firms participating in private placements. While the details of each transaction differ, FINRA’s focus remains remarkably consistent:

• Reasonable due diligence

• Supervision

• Communications with investors

• Private placement filing requirements

• Documentation supporting the firm’s review

None of these are new concepts. They continue to form the foundation of FINRA’s expectations for registered representatives engaged in private placement activity.

Due Diligence Is a Shared Responsibility

One common misconception is that due diligence is solely the responsibility of a firm’s compliance department. In reality, it’s a shared effort. FINRA places the supervisory obligation on the broker-dealer, but registered representatives play an equally important role. In most transactions, the representative knows the issuer best and is responsible for understanding the business, asking thoughtful questions, identifying potential risks, and bringing any concerns to the firm’s attention.

At Britehorn, for example, our compliance team doesn’t attempt to duplicate the representative’s work or collect and review every possible document for each rep's deal. Rather, our role is to supervise the process and confirm that an appropriate level of due diligence has been performed based on the facts and circumstances of each offering.

That’s an important distinction.

FINRA isn’t looking for every firm to collect the exact same documents or follow a rigid checklist. Instead, it expects firms to have a reasonable process for understanding the issuer and identifying potential red flags before permitting representatives to market an offering.

Reasonable Investigation Comes First

So what does a “reasonable investigation” actually look like? Regulatory Notice 23-08 explains that reps should understand, among other things:

• the issuer and its business;

• the management team and key principals;

• the issuer’s business prospects;

• assets owned or to be acquired;

• how offering proceeds will be used; and

• the representations being made to prospective investors.

Depending on the circumstances, a reasonable investigation may also include reviewing:

• litigation history;

• regulatory actions;

• disciplinary history;

• criminal matters;

• affiliated entities;

• beneficial ownership;

• Rule 506(d) “Bad Actor” disqualification issues;

• material contracts;

• financial statements; and

• significant developments that occur while the offering remains open.

The appropriate level of diligence will vary depending on the issuer, industry, complexity of the transaction, and overall risk profile. A newly formed fund with multiple affiliated entities may require significantly more investigation than an established operating company with audited financial statements and a long operating history.

The key takeaway is that representatives should understand the opportunity well enough to answer reasonable investor questions — and recognize when something warrants additional review.

Reviewing the PPM Isn’t Enough

Many issuers work with experienced securities counsel to prepare offering documents, and a well-written Private Placement Memorandum (PPM) is certainly an important part of any capital raise.

But FINRA has consistently stated that reviewing the PPM alone does not satisfy due diligence obligations. Instead, reps are expected to evaluate whether the information presented appears reasonable and whether there are any obvious inconsistencies or red flags requiring additional inquiry. In other words, due diligence is an active process — not simply a review of disclosure documents.

Marketing Materials Still Matter

Private placements are exempt from SEC registration, but that doesn’t mean marketing materials receive less scrutiny.

Pitch decks, executive summaries, investor presentations, webinars, email campaigns, and similar communications remain subject to FINRA Rule 2210, which requires communications to be fair, balanced, and not misleading.

Representatives should ensure that marketing materials:

• accurately describe the issuer and offering;

• avoid exaggerated or unsupported claims;

• fairly discuss material risks;

• remain consistent with the offering documents; and

• are reviewed through the firm’s supervisory process before distribution, where required.

It’s often these materials — not the PPM — that create unnecessary regulatory risk when enthusiasm gets ahead of the facts.

While we at Britehorn review all our reps' marketing materials before they go out to potential investors, we also encourage all our reps to understands the rules and do their own reviews first.

What About Regulation Best Interest?

Whenever private placement compliance is discussed, Regulation Best Interest (“Reg BI”) inevitably enters the conversation. It has been a big area of focus for both the SEC and FINRA ever since it passed in 2020, and it continues to pop up in all their stated oversign reports.

Reg BI applies when reps make recommendations to retail customers, imposing additional obligations relating to disclosures, conflicts of interest, policies and procedures, and documenting why a recommendation is in the customer’s best interest.

At Britehorn, however, we do not allow our reps to solicit investments from retail customers. Our registered representatives can only work with institutional investors (or through licensed channels such as investment advisors, wealth managers, and family offices). As a result, our representatives are not making recommendations that trigger Reg BI or the associated Form CRS requirements. That significantly simplifies our compliance requirements across the board for all our reps.

Due Diligence Protects Everyone

It’s easy to think of due diligence as simply another compliance requirement. In reality, it protects everyone involved in the transaction. A thoughtful diligence process helps:

• identify issues before investors do;

• uncover litigation or regulatory concerns early;

• improve credibility during investor discussions;

• reduce the likelihood of surprises after launch; and

• demonstrate that reasonable questions were asked before capital was raised.

For experienced investment bankers, due diligence often becomes a competitive advantage. Institutional investors appreciate representatives who understand an issuer’s business, can answer detailed questions confidently, and have already addressed potential concerns before beginning the marketing process.

Practical Takeaways

Before bringing a private placement to your broker-dealer for approval, consider asking yourself:

• Do I have a solid understanding of the issuer’s business and management team?

• Have I reviewed the offering carefully enough to answer reasonable investor questions?

• Have I identified any litigation, regulatory, financial, or operational issues that should be discussed with compliance?

• Are the marketing materials accurate, balanced, and consistent with the offering documents?

• Would I feel comfortable explaining how I satisfied my due diligence obligations if FINRA asked six months from now?

If the answer to those questions is “yes,” you’re already well on your way toward meeting FINRA’s expectations.

Final Thoughts

The biggest takeaway from FINRA’s 2026 guidance is that private placement due diligence isn’t becoming more complicated — it’s becoming more important. FINRA continues to expect broker-dealers and their registered representatives to understand the offerings they market, investigate potential red flags, supervise the process appropriately, and maintain documentation supporting the work performed.

For representatives, that shouldn’t be viewed as a regulatory hurdle. It should have always been a part of your process to understand the businesses you’re representing, be able to have productive conversations with prospective investors, and only bring high-quality offerings to market.

Those fundamental expectations have not changed — there might just be an added layer of expected oversight.
