The short version

David O'Brien is listed as an executive officer and director on 2 SEC Form D filings by 2 issuers between Nov 2009 and Aug 2021: Plutonic Power CORP (Vancouver Bc, British Columbia, Canada (as filed: A1) — other energy — 2009; $13.2M reported sold to 3 investors) and Stuhini Exploration Ltd. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2021; $219K reported sold to 9 investors).

What this means 2 separate companies raised money with this person listed as executive officer and director, over about 12 years. Across those companies the filings report $13.4M sold in total.

Listed alongside Barry Hanslit (1 shared filing), Charles Shigeo Kamimura (1 shared filing), Donald A. McInnes (1 shared filing), Ehsan Salmabadi (1 shared filing), Fiore Aliperti (1 shared filing) and 13 others.

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CO, CT, DC, DE, FINRA, FL, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, NY, OH, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, WA, WI, WV, WY) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 2 public filings for David O'Brien and found 5 differences, 1 worth asking the sponsor about: 9 paid sellers are listed without a CRD number; 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.

4. Differences between public sources

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

5 differences found between the filings for David O'Brien — 1 worth asking about (compared 2 filings on Oct 24, 2026)

Worth asking · Nov 19, 2009

9 paid sellers are listed without a CRD number

Paid seller listed without a CRD number: GMP Securities L.P. — Plutonic Power CORP · Paid seller listed without a CRD number: Macquarie Capital Markets Canada Ltd. — Plutonic Power CORP · Paid seller listed without a CRD number: Scotia Capital Inc. — Plutonic Power CORP · Paid seller listed without a CRD number: Toll Cross Securities Inc. — Plutonic Power CORP · Paid seller listed without a CRD number: Canaccord Capital Corporation — Plutonic Power CORP · and 4 more

What this means Without a CRD number we cannot look a seller up on BrokerCheck. Ask who they are and whether they are registered.

Sources
Note · Jul 23, 2021 – Aug 9, 2021

Form D filed 17 days after the first sale — Stuhini Exploration Ltd.

The filing says the first sale was Jul 23, 2021. The Form D was filed Aug 9, 2021 — 17 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 2 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.

Same name, different state: "David O'Brien" (NY) is a separate record

This page covers filings where the address state is A1. A separate record, "David O'Brien" with address state NY, is listed on 9 filings — most recently by HR US Infra Equity LP (May 20, 2020). Both records have filings in the same period (Nov 19, 2009 to May 20, 2020).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

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).

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file).

Adviser registration (Form ADV)

None of the 2 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to David O'Brien by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 2 issuers this person is listed on — nothing matched.
