The short version

Mark A. Zwecker is listed as a director on 6 SEC Form D filings by 1 issuer between May 2009 and Apr 2019: PERMA FIX ENVIRONMENTAL SERVICES INC (Atlanta, GA — environmental services — 2009–2019; $3M reported sold to 13 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 Ben Naccarato (6 shared filings), Joe R. Reeder (6 shared filings), Larry M. Shelton (6 shared filings), Dr. Louis F. Centofanti (5 shared filings), Mark Duff (4 shared filings) and 15 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Mark. 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) — 3 court cases matching the name listed in Key records below.

What this means 3 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 Mark A. Zwecker and found 4 differences: No amendment in the last 12 months on an offering that may still be open; Mark A. Zwecker is written 2 different ways on the 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

4 differences found between the filings for Mark A. Zwecker (compared 6 filings on Oct 24, 2026)

Note · May 8, 2009 – May 21, 2009

No amendment in the last 12 months on an offering that may still be open — PERMA FIX ENVIRONMENTAL SERVICES INC (latest filing May 21, 2009)

The latest filing for this offering is dated May 21, 2009 (first sale May 8, 2009). It reports $476,000 sold of an indefinite amount offered. No later amendment is in our index as of Oct 24, 2026.

What this means SEC rules expect a yearly amendment while an offering is still going. The raise may simply have ended — a Form D does not say when it closed. Ask the sponsor whether the offering closed, when, and at what amount.

Sources
Note · May 21, 2009 – Aug 13, 2013

Mark A. Zwecker is written 2 different ways on the filings

listed as "Mark A. Zwecker" on 3 filings (from May 21, 2009), and "Mark Zwecker" on 3 filings (from Aug 13, 2013).

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 · May 21, 2009 – Aug 13, 2013

Industry group changed between filings — PERMA FIX ENVIRONMENTAL SERVICES INC

"Other" (May 21, 2009); then "Environmental Services" (Aug 13, 2013 to Apr 3, 2019).

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

Sources
Note · May 21, 2009 – Aug 4, 2016

Reported revenue range changed between filings — PERMA FIX ENVIRONMENTAL SERVICES INC

"$25,000,001 - $100,000,000" (May 21, 2009); then "Over $100,000,000" (Aug 13, 2013); then "$25,000,001 - $100,000,000" (Aug 4, 2016).

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.

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).
