The short version

William Hamilton is listed as a director on 6 SEC Form D filings by 2 issuers between May 2009 and May 2012: AVID RADIOPHARMACEUTICALS, INC. (Philadelphia, PA — pharmaceuticals — 2009; $34.5M reported sold to 14 investors) and CEPTARIS THERAPEUTICS, INC (Malvern, PA — pharmaceuticals — 2009–2012; $8.29M reported sold to 33 investors).

What this means 2 separate companies raised money with this person listed as director, over about 3 years. Across those companies the filings report $42.8M sold in total.

Listed alongside Greg Vontz (3 shared filings), Alan P. Carpenter (2 shared filings), Albert Cha (2 shared filings), Daniel M. Skovronsky (2 shared filings), David C. Drahms (2 shared filings) and 18 others.

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

1 of the issuers belongs to the sponsor group Ceptaris (2 issuers, $24.1M reported sold, 2009–2012).

What this means A sponsor group is one team that sets up a new company for each deal. Ceptaris has 2 companies on file and $24.1M 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) — 1 SEC release, 18 bankruptcy cases matching the name listed in Key records below.

What this means 19 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 6 public filings for William Hamilton and found 18 differences, 3 worth asking the sponsor about: Regulator action: William Paul Hamilton (Aug 8, 2018); 39% of the money raised went to insiders; 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.

A ap release dated Aug 8, 2018 names William Hamilton. Our match estimate: 40%. The release is the source; we do not summarize its outcome here.

The filing says the first sale was Nov 5, 2010. The Form D was filed Nov 22, 2010 — 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: "WILLIAM M, HAMILTON" (TX) is a separate record

This page covers filings where the address state is PA. A separate record, "WILLIAM M, HAMILTON" with address state TX, is listed on 1 filing — most recently by MSH HOLDINGS, LLC (May 20, 2013). The two records do not overlap in time: this page runs May 20, 2009 to May 22, 2012; the other has one filing dated May 20, 2013.

What this means Could be the same person who moved, or two people with the same name. We keep them apart until a filing ties them together. Check both pages before you decide.

The people listed on the Nov 22, 2010 filing give Radnor, PA; on the Aug 17, 2011 filing they give Malvern, PA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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.

5. Money to insiders

0 of 5 offerings report sales commissions; 0 report finder's fees; 2 report proceeds to related persons totalling $6,200,000. (includes amounts the issuer reported as estimates)

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 William Hamilton 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.
