The short version

Guy Cook is listed as an executive officer and director on 5 SEC Form D filings by 1 issuer between Jan 2016 and Apr 2017: Lattice Biologics Ltd. (Scottsdale, AZ — biotechnology — 2016–2017; $8.42M reported sold to 15 investors).

What this means One deal on file with the SEC. A Form D is the notice a company files after it starts selling a private investment — it is a notice, not an approval.

Listed alongside Catherine Thomas (5 shared filings), Donald McInnes (5 shared filings), Mario Stifano (5 shared filings), Cheryl Farmer (4 shared filings) and Gregory Charles Davis (2 shared filings).

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 13 bankruptcy cases matching the name listed in Key records below.

What this means 13 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 Guy Cook and found 6 differences: Form D filed 24 days after the first sale; Offering amount changed between filings; 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

6 differences found between the filings for Guy Cook (compared 5 filings on Oct 24, 2026)

Note · Jan 23, 2017 – Feb 16, 2017

Form D filed 24 days after the first sale — Lattice Biologics Ltd.

The filing says the first sale was Jan 23, 2017. The Form D was filed Feb 16, 2017 — 24 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 9 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.

Sources
Note · Mar 14, 2017 – Apr 18, 2017

Offering amount changed between filings — Lattice Biologics Ltd.

The Mar 14, 2017 filing says $283,236 offered; the Apr 18, 2017 Form D/A says $371,376.

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.

Sources
Note · Feb 16, 2017 – Mar 14, 2017

Offering amount changed between filings — Lattice Biologics Ltd.

The Feb 16, 2017 filing says $258,416 offered; the Mar 14, 2017 Form D/A says $283,236.

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.

Sources
Note · Jan 6, 2016 – Feb 16, 2017

Guy Cook is written 2 different ways on the filings

listed as "Guy Sumner Cook" on 2 filings (from Jan 6, 2016), and "Guy Cook" on 3 filings (from Feb 16, 2017).

What this means Same person, written differently — a middle name or suffix left off, or spelled another way. It is normal, but check that the full legal name matches your subscription documents.

Sources
Note · Jan 28, 2010 – Jul 14, 2010

Same name, different state: "Guy S. Cook" (MT) is a separate record

This page covers filings where the address state is AZ. A separate record, "Guy S. Cook" with address state MT, is listed on 9 filings — most recently by Xtant Medical Holdings, Inc. (May 31, 2011). The two records do not overlap in time: this page runs Feb 16, 2017 to Apr 18, 2017; the other runs Jan 28, 2010 to Jul 14, 2010.

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.

Sources
Note · Jan 6, 2016 – Feb 16, 2017

Reported revenue range changed between filings — Lattice Biologics Ltd.

"$1,000,001 - $5,000,000" (Jan 6, 2016); then "Decline to Disclose" (Feb 16, 2017).

What this means This is the size band the issuer picks for itself on the form. A change can mean the business grew or shrank — or that it chose not to say. Ask for current numbers.

Sources
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

None reported on 3 offerings — no sales commissions, finder's fees or proceeds to insiders
