The short version

Stephane Mailhot is listed as an executive officer and director on 51 SEC Form D filings by 7 issuers between Jun 2016 and Sep 2026. Largest by amount reported sold: AxInfra US LP (New York, NY — pooled investment fund — 2017–2025; $3.53B reported sold to 10 investors), AxInfra US III LP (Montreal, Quebec, Canada (as filed: A8) — pooled investment fund — 2021–2022; $1.78B reported sold to 14 investors), AXIUM INFRASTRUCTURE NA IV LP (Toronto, Ontario, Canada (as filed: A6) — pooled investment fund — 2017–2026; $1.35B reported sold to 58 investors), Axium Infrastructure Canada II (Intl) Limited Partnership (Montreal, Quebec, Canada (as filed: A8) — pooled investment fund — 2017–2026; $1.34B reported sold to 14 investors), AxInfra US II LP (New York, NY — pooled investment fund — 2017–2026; $1.16B reported sold to 11 investors) and 2 more (all listed below).

What this means A repeat sponsor — 7 separate companies raised money with this person listed as executive officer and director, over about 10 years. Across those companies the filings report $10.2B sold in total.

Listed alongside Jean Eric Laferriere (50 shared filings), Thierry Vandal (28 shared filings), Pierre Anctil (23 shared filings), Juan Caceres (14 shared filings), Anick Sivret (9 shared filings) and 1 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Stephane. Each name links to their own page.

All 7 issuers belong to the sponsor group Axinfra (7 issuers, $9.35B reported sold, 2012–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Axinfra has 7 companies on file and $9.35B reported sold in total — the group page shows the whole track record in one place.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 4 court cases matching the name, 2 bankruptcy cases matching the name listed in Key records below.

What this means 6 records came back. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared the newest 50 of 51 public filings for Stephane Mailhot and found 8 differences: Form D filed 25 days after the first sale; Form D filed 32 days after the first sale; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

8 differences found between the filings for Stephane Mailhot (compared the newest 50 of 51 filings on Oct 24, 2026; older filings not covered)

Note · Sep 3, 2021 – Sep 28, 2021

Form D filed 25 days after the first sale — AxInfra US III LP

The filing says the first sale was Sep 3, 2021. The Form D was filed Sep 28, 2021 — 25 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 10 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Note · Sep 3, 2021 – Sep 15, 2022

No amendment in the last 12 months on an offering that may still be open — AxInfra US III LP (latest filing Sep 15, 2022)

The latest filing for this offering is dated Sep 15, 2022 (first sale Sep 3, 2021). It reports $1,783,772,708 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Address moved from New York, NY to Montreal, Quebec, Canada (as filed: A8) — AXIUM INFRASTRUCTURE NA IV LP

The people listed on the Apr 11, 2016 filing give New York, NY; on the Apr 10, 2017 filing they give Montreal, Quebec, Canada (as filed: A8). The address now on file (120 Adelaide Street West, Suite 425, Toronto, Ontario, Canada (as filed: A6)) is a registered-agent or shared-office address used by 13 issuers.

What this means A registered agent's address is a mailbox, not where the team works. Ask where the business actually operates.

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

Formed in 2022 per the latest filing, but activity is dated 2016 — AXIUM INFRASTRUCTURE NA IV LP

The issuer's latest filing says it was formed in 2022. The Apr 11, 2016 filing says the first sale was Mar 18, 2016 — before that year.

What this means A company cannot sell before it exists, so one of the two dates is likely a typo on the form. Ask the sponsor for the formation document.

What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. We compared the newest 50 of 51 filings (work cap); older filings are not covered here. As of Oct 24, 2026.

How this is counted

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

Counted across every filing this person is listed on (latest filing per offering, per issuer).

Deals 7

Every issuer that named Stephane Mailhot on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
