The short version

Mark Brennan is listed as an executive officer and director on 5 SEC Form D filings by 4 issuers between Oct 2010 and Dec 2023: Largo Inc. (Toronto, Ontario, Ontario, Canada (as filed: A6) — industry reported as "Other" — 2010; $12.7M reported sold to 16 investors), Cerrado Gold Inc. (Toronto, Ontario, Canada (as filed: A6) — industry reported as "Other" — 2020–2021; $4M reported sold to 4 investors), Castle Resources Inc.

What this means A repeat sponsor — 4 separate companies raised money with this person listed as executive officer and director, over about 13 years. Across those companies the filings report $17.9M sold in total.

Listed alongside Stephen Shefsky (4 shared filings), Kurt Menchen (3 shared filings), Robert Campbell (3 shared filings), Cliff Hale-Sanders (2 shared filings), Elmer Prata Salomao (2 shared filings) and 22 others.

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

1 of the issuers belongs to the sponsor group Largo (2 issuers, $6.3M reported sold, 2010–2025).

What this means A sponsor group is one team that sets up a new company for each deal. Largo has 2 companies on file and $6.3M 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 (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 1 court case matching the name, 28 bankruptcy cases matching the name listed in Key records below.

What this means 29 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 5 public filings for Mark Brennan and found 7 differences, 1 worth asking the sponsor about: Paid seller listed without a CRD number: Canaccord Genuity Corp; 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.

State courts: not covered (one-tap state court links under Look further). No state offers a lawful automated statewide source PartnerFacts can use today. Texas (re:SearchTX) terms prohibit storing results in a database open to third parties; New York (WebCivil) and Massachusetts (MassCourts) require a browser check that blocks scripted queries; California has no statewide index (58 county portals; Rule of Court 2.503 grants name-based access case by case); Florida, Utah and Illinois offer paid or partial access whose terms for automated use are unverified. Washington (dw.courts.wa.gov; bulk index reports under a JISC data-dissemination agreement), Delaware (CourtConnect; Court of Chancery not included) and Arizona (apps.azcourts.gov/publicaccess, which has an official channel to request high-volume access) are the candidates; PartnerFacts will request written permission before any automated search.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

7 differences found between the filings for Mark Brennan — 1 worth asking about (compared 5 filings on Oct 24, 2026)

Worth asking · Dec 29, 2023

Paid seller listed without a CRD number: Canaccord Genuity Corp. — Ascendant Resources Inc.

Canaccord Genuity Corp. is listed as receiving sales compensation on 1 filing (Dec 29, 2023) with no FINRA CRD number given.

What this means People paid to sell securities normally hold a FINRA registration with a CRD number. Without one we cannot look them up on BrokerCheck. Ask who they are and whether they are registered.

Form D filed 22 days after the first sale — Largo Inc.

The filing says the first sale was Sep 16, 2010. The Form D was filed Oct 8, 2010 — 22 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 7 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.

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. 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 4

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