What is Reg S, and what does it change about your ads?

Regulation S is the rule that lets a company sell securities to investors outside the United States without registering that offering with the SEC. It is usually run alongside a domestic offering rather than on its own, most often a Reg D private placement for American accredited investors paired with a Reg S offering for everyone else. The definition, the safe harbors, and the category system are in regulation-s.

Before any of that, though, the honest answer for most companies reading this: you probably do not need it, and almost nobody does it.

Why almost nobody runs a Reg S

Reg S comes up constantly in conversations about raising money, usually in the form "we have international interest, so we need a Reg S". Most of the time that conclusion is wrong, for three reasons.

Foreign investors can usually invest in your domestic offering already. This is the big one, and it surprises people. Reg CF and Reg A+ restrict who may issue, generally requiring a company organized and principally operating in the United States or Canada. They do not carry a blanket requirement that investors be American. A qualified Reg A+ offering can generally take money from someone in Berlin or Singapore. So a company reaching for Reg S in order to accept foreign investors is often solving a problem it does not have.

When international investors cannot participate, the blocker is usually the platform rather than the exemption: portals and broker-dealers limit which countries they will onboard, because identity verification, sanctions screening, and payment rails are harder across borders. That is a vendor question, and the fix is asking your platform which countries it supports before assuming you need a second offering.

Reg S is a United States safe harbor, not a global permission slip. This is the reason the whole idea collapses more often than not. Reg S says the SEC will not treat your offshore sales as requiring US registration. It says nothing whatsoever about the securities laws of the country you are advertising into. Canada, the UK, the EU, Australia, and Japan each have their own regime governing who may promote an investment to their residents and how. Running a Reg S does not make marketing an offering to Germans legal under German law.

So the company that adds Reg S expecting to unlock global advertising discovers it has taken on a second compliance problem in every country it wants to enter, on top of the one it already had.

The cost is real and lands before any money does. A second set of offering documents, counsel time to determine the category and its distribution compliance period, restricted securities and transfer restrictions to administer, and the no-directed-selling-efforts condition described below, which turns your US marketing from an asset into a liability. That is a meaningful spend against an audience whose size you are guessing at.

Put together, the overwhelming majority of raises are better served by the three domestic exemptions alone: Reg CF for smaller public raises, Reg A+ for larger ones, and Reg D 506(c) for accredited investors with the freedom to advertise. Those three cover nearly every company that will ever read this, and they are what almost every raise actually uses.

When Reg S genuinely earns its place

It is not useless. It earns its keep in a narrow set of situations.

You have identified, concentrated offshore demand. Not a hope that foreigners will be interested, but a real audience: an existing international customer base, a diaspora market with a genuine connection to what you are building, a partner or distributor network overseas. Demand you can name and size.

You need capacity your domestic exemption does not have. Reg S carries no dollar cap. A company bumping against the seventy five million dollar Tier 2 ceiling, or running a 506(b) placement that cannot be advertised at all, has a structural reason to look offshore.

Your platform or your jurisdiction forces it. Some structures and some issuers simply need it, and counsel will tell you so.

If none of those describe you, the useful move is to stop here and put the effort into the domestic campaign instead. If one of them does, the rest of this post is about what it does to the marketing, which is more than most people expect.

The rule that governs your media plan

Regulation S rests on two conditions: the transaction has to be offshore, and there can be no directed selling efforts in the United States.

That second phrase is the one to internalize. It does not mean "do not sell to Americans". It means do not do anything that could reasonably be expected to condition the US market for these securities. Advertising, press, mailings, and promotional material aimed at the United States can all count, whether or not a single American invests.

So the geo settings in your ad accounts stop being an optimization lever and become a compliance control. That reframing changes how the whole campaign is built.

Where campaigns leak into the United States

In our experience the leaks are rarely deliberate. They are defaults nobody thought about.

Broad targeting and automated expansion. Modern ad platforms are built to widen delivery when it improves results, and the tools that do it are on by default in a lot of campaign types. Anything that can expand an audience can expand it into the country you are excluding. Turn it off explicitly and check delivery by country rather than trusting the setting.

Lookalike and similar audiences built from US seed data. If the seed list has Americans in it, you are asking the platform to find more of them.

Organic and press spillover. An announcement picked up by US publications, a founder interview on a US podcast, an untargeted post on the company's own social accounts. Paid media gets the attention here and earned media is where the surprises live.

The website itself. If a US visitor can land on the offering page and start a process, the geographic line is being drawn by your ad settings alone, which is thin. Gating, routing, and a clear statement of who the offering is open to belong on the page.

US persons abroad. The definition of a US person is about status, not location. IP-based geo-targeting does not see that distinction, which is one of several reasons the actual eligibility determination happens at the point of investment and not in the ad account.

Retargeting pools. Retargeting is among the most efficient spend in most raises, and it inherits whatever is in the pixel pool. If US traffic ever accumulated there, it needs to be excluded deliberately.

Your securities counsel sets the actual boundaries here. What a marketing team owns is making sure the campaign's settings, the site, and the earned media plan all reflect the same boundary, and that somebody checks delivery reports by country every week rather than assuming.

What changes in the creative

Running a raise across many countries is not the same campaign translated.

The offer has to be explained to people who do not share the American frame of reference for startup investing, and in some markets the entire concept of buying equity in a private company online is unfamiliar. Payment and currency friction is real and shows up as drop-off between a started investment and a completed one, which is where most raises leak anyway.

The useful instinct is to stop thinking about it as one international campaign and start treating the two or three countries that actually respond as their own campaigns, with their own creative and their own numbers. Cost per completed investment varies enormously by market, and the averages hide it.

What to settle before launch

• Which exemptions are running and who each one is for. Reg S plus 506(b) is a very different marketing plan from Reg S plus 506(c), because one of those can be advertised domestically and one cannot. See reg-a-plus-and-reg-d-at-once.
• Written geographic rules for every channel, including organic social and press, not just the ad accounts.
• Eligibility on the page, not only in the targeting.
• Reporting split by country, with cost per completed investment for each, since the whole point of Reg S is finding where the money actually is.

This is general information about a securities rule, not legal advice. What your offering may do, and where, is a question for your own securities counsel.

FAQ

What is Regulation S?

A safe harbor under which offers and sales of securities made outside the United States are not subject to the Securities Act's registration requirement. It requires an offshore transaction and no directed selling efforts in the United States, and it has no dollar cap.

Do I need a Reg S to take investment from people outside the United States?

Usually not. Reg CF and Reg A+ restrict who may issue, generally requiring a company organized and operating in the United States or Canada, but they do not carry a blanket requirement that investors be American. When foreign investors cannot participate, the limit is more often the portal's or broker-dealer's onboarding and identity verification than the exemption itself. Ask your platform which countries it supports before adding a second offering.

Why do so few companies run a Regulation S offering?

Because it usually solves a problem they do not have, and creates one they did not expect. Foreign investors can often already participate in a domestic offering, and Reg S is a United States safe harbor that says nothing about the securities laws of the country you are marketing into. Most raises are well served by Reg CF, Reg A+, and Reg D 506(c) alone.

Does Regulation S let me advertise my offering in other countries?

No. Reg S governs your position under United States law. Every country you promote an investment in has its own rules about who may do that and how, and those apply regardless of Reg S. Marketing into another jurisdiction is a question for counsel qualified in that jurisdiction.

Can you advertise a Reg S offering?

Yes, outside the United States. What you cannot do is conduct directed selling efforts in the US, which is broader than advertising and can include press and promotional activity that conditions the US market for the securities. Geographic controls become a compliance matter rather than a performance setting.

Can Americans invest through Regulation S?

No. Regulation S is the offshore side of a raise. Companies that want both audiences typically pair it with a domestic exemption such as Regulation D for accredited US investors, or run a public offering under Regulation A+.

What is the biggest practical mistake in a Reg S campaign?

Leaving automated audience expansion on, or building lookalike audiences from a seed list containing US data, and then discovering from a delivery report that impressions have been served in the United States. Check delivery by country every week rather than trusting the exclusion setting.
