The short version

Chestnut is a sponsor group of 13 issuers that PartnerFacts links to one sponsor (shared people, same business address, similar issuer names; automatic match from the filings), filing 18 Form D filings between Apr 2009 and Sep 2015.

What this means One team, 13 deal companies, about 6 years of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $3.26M to 19 investors (latest filing per issuer). Industries as reported: Oil and Gas (13). Issuers are based in TX (13).

What this means $3.26M raised across the group, about $171K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Mark A Plummer (13 issuers, executive officer and director).

What this means 13 deals for a one-person team on paper. The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 0 new offerings in the last 12 months; latest filing Sep 4, 2015.

What this means No new raise filed in the past year.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA), property records (NYC, FL, IL and TX counties) — 3 court cases matching the name, 2 bankruptcy cases matching the name listed in Key records below.

What this means 5 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 18 public filings for Chestnut and found 6 differences: Form D filed 32 days after the first sale; 5 offerings have no amendment in the last 12 months and may still be open; 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

No comparisons published

What is compared

No public statement by this sponsor group has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this sponsor group yet.

6 differences found between the filings for Chestnut (compared 18 filings on Oct 24, 2026)

Note · Nov 13, 2009 – Dec 15, 2009

Form D filed 32 days after the first sale — Chestnut Production Fund III, L.P.

The filing says the first sale was Nov 13, 2009. The Form D was filed Dec 15, 2009 — 32 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 17 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.

Form D · Dec 15, 2009 ↗Chestnut Production Fund III, L.P. — PartnerFacts page ↗

Note · Nov 13, 2009 – Nov 20, 2012

5 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 — Chestnut Exploration, Inc. (latest filing Nov 20, 2012) · No amendment in the last 12 months on an offering that may still be open — Chestnut Well Service I, L.P. (latest filing Oct 5, 2011) · No amendment in the last 12 months on an offering that may still be open — Chestnut Exploration, Inc. Sun Oil 14 Re-Entry Joint Venture (latest filing May 11, 2011) · No amendment in the last 12 months on an offering that may still be open — Chestnut Moss Bluff #3 Joint Venture (latest filing Mar 4, 2011) · No amendment in the last 12 months on an offering that may still be open — Chestnut Production Fund III, L.P. (latest filing Dec 15, 2009)

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

Mark A Plummer is written 2 different ways on the filings

listed as "Mark Plummer" on 5 filings (from Apr 23, 2009), and "Mark A Plummer" on 13 filings (from May 11, 2011).

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.

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 all 13 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
