The short version

David Sidoo is listed as an executive officer, director, and promoter on 7 SEC Form D filings by 3 issuers between Oct 2010 and Aug 2019: East West Petroleum Corp. (Vancouver, British Columbia, Canada (as filed: A1) — oil and gas — 2010–2011; $5.78M reported sold to 29 investors), Advantage Lithium Corp. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2016–2019; $799K reported sold to 16 investors) and Liberty Defense Holdings, Inc. (Vancouver, British Columbia, Canada (as filed: A1) — industry reported as "Other" — 2019; $160K reported sold to 10 investors).

What this means A repeat sponsor — 3 separate companies raised money with this person listed as executive officer, director, and promoter, over about 9 years. Across those companies the filings report $6.74M sold in total.

Listed alongside Nick DeMare (5 shared filings), Callum Grant (4 shared filings), Ross McElroy (3 shared filings), Devinder Randhawa (2 shared filings), Greg Renwick (2 shared filings) and 17 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.

1 of the issuers belongs to the sponsor group East West (2 issuers, $5.89M reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. East West has 2 companies on file and $5.89M 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, 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 7 public filings for David Sidoo and found 8 differences, 1 worth asking the sponsor about: Paid seller listed without a CRD number: Haywood Securities Inc; 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

8 differences found between the filings for David Sidoo — 1 worth asking about (compared 7 filings on Oct 24, 2026)

Note · Aug 28, 2019

David Sidoo appears on 1 deal that stopped filing before reaching its target

Advantage Lithium Corp. (last filing Aug 28, 2019; $798,918 sold of $6,534,694). Each has no filing in more than two years and reported under half its target sold.

What this means An issuer whose last filing is more than two years old and reported under half its target sold. The raise may have closed early or quietly stopped. Ask what happened to each.

Worth asking · Jan 5, 2011

Paid seller listed without a CRD number: Haywood Securities Inc. — East West Petroleum Corp.

Haywood Securities Inc. is listed as receiving sales compensation on 1 filing (Jan 5, 2011) 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 16 days after the first sale — Advantage Lithium Corp.

The filing says the first sale was Aug 12, 2019. The Form D was filed Aug 28, 2019 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 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.

The filing says the first sale was Feb 17, 2017. The Form D was filed Mar 6, 2017 — 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.

No amendment in the last 12 months on an offering that may still be open — Advantage Lithium Corp. (latest filing Nov 6, 2017) · No amendment in the last 12 months on an offering that may still be open — Advantage Lithium Corp.

(latest filing Jan 5, 2011) · No amendment in the last 12 months on an offering that may still be open — East West Petroleum Corp. (latest filing Oct 13, 2010)

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

David Sidoo's role changed at Advantage Lithium Corp.: executive officer, director, promoter → director

The Nov 6, 2017 filing lists David Sidoo as executive officer, director, promoter; the Aug 28, 2019 Form D lists director.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

The Oct 28, 2016 filing says $6,247,994 offered; the Nov 6, 2017 Form D/A says $6,534,694.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

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).

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

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 3 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 Sidoo 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 3 issuers this person is listed on — nothing matched.
