The short version

Robert Zerbe is listed as a director on 9 SEC Form D filings by 4 issuers between Jul 2009 and Oct 2025: CymaBay Therapeutics, Inc. (Newark, CA — biotechnology — 2009; $30.2M reported sold to 335 investors), Cirius Therapeutics, Inc. (Grand Rapids, MI — biotechnology — 2017–2025; $30M reported sold to 30 investors), Octeta Therapeutics, LLC (Kalamazoo, MI — biotechnology — 2016; $16.4M reported sold to 21 investors) and METABOLIC SOLUTIONS DEVELOPMENT CO LLC (Kalamazoo, MI — pharmaceuticals — 2015–2019; $16.1M reported sold to 30 investors).

What this means A repeat sponsor — 4 separate companies raised money with this person listed as director, over about 16 years. Across those companies the filings report $92.7M sold in total.

Listed alongside Michael Jandernoa (7 shared filings), David Van Andel (5 shared filings), Mark Olesnavage (4 shared filings), Angeline Shashlo (3 shared filings), Jerry Callahan (3 shared filings) and 26 others.

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

2 of the issuers belong to the sponsor group Metabolic (4 issuers, $60.8M reported sold, 2009–2019).

What this means A sponsor group is one team that sets up a new company for each deal. Metabolic has 4 companies on file and $60.8M 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) — 2 bankruptcy cases matching the name listed in Key records below.

What this means 2 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 9 public filings for Robert Zerbe and found 10 differences, 1 worth asking the sponsor about: Amount sold went down 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

10 differences found between the filings for Robert Zerbe — 1 worth asking about (compared 9 filings on Oct 24, 2026)

Worth asking · Jul 21, 2009 – Nov 10, 2009

Amount sold went down between filings — CymaBay Therapeutics, Inc.

The Jul 21, 2009 filing says $27,747,055 sold; the Nov 10, 2009 Form D says $5,583,320 sold — $22,163,735 less.

What this means Amounts sold normally only go up as a raise continues. A drop can mean investors were refunded, a figure was corrected, or an earlier number was wrong. Ask the sponsor which it was.

Note · Jul 12, 2024 – Aug 20, 2024

Form D filed 39 days after the first sale — Cirius Therapeutics, Inc.

The filing says the first sale was Jul 12, 2024. The Form D was filed Aug 20, 2024 — 39 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 24 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 this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

6 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — Cirius Therapeutics, Inc. (latest filing Oct 8, 2025) · No amendment in the last 12 months on an offering that may still be open — Cirius Therapeutics, Inc. (latest filing Oct 15, 2024) · No amendment in the last 12 months on an offering that may still be open — Cirius Therapeutics, Inc.

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

The Jul 18, 2014 filing says $14,000,000 offered; the Sep 24, 2015 Form D/A says $18,400,000.

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 this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

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.

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); KY (Kentucky Secretary of State — Business Entity Search (sosbes.sos.ky.gov), searched by issuer name, data as of Oct 24, 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 4 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 Robert Zerbe 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 4 issuers this person is listed on — nothing matched.
