The short version

Nelson Obus is listed as a director on 1 SEC Form D filing by 1 issuer in Feb 2015: LAYNE CHRISTENSEN CO (The Woodlands, TX — industry reported as "Other" — 2015; $99.9M reported sold to 24 investors).

What this means One deal on file with the SEC, filed Feb 2015. 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 Andrew T. Atchison (1 shared filing), David A.B. Brown (1 shared filing), J. Samuel Butler (1 shared filing), John T. Nesser III (1 shared filing), Kent M. Wartick (1 shared filing) and 8 others.

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

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY) — 3 court cases matching the name, 2 SEC releases 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 1 public filing for Nelson Obus and found 5 differences, 3 worth asking the sponsor about: Regulator action: Nelson J. Obus, Peter F. Black, Thomas Bradley Strickland, et. al. (Jun 2, 2014); Regulator action: Nelson J. Obus, Peter F. Black, Thomas Bradley Strickland, Wynnefield Partners Small Cap Value L.P., Wynnefield Partners Small Cap Value L.P. I, Wynnefield Partners Small Cap Value Offshore Fund, Ltd. (Apr 25, 2006); 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.

Same name, different state: "Nelson J Obus" (NY) is a separate record

This page covers filings where the address state is TX. A separate record, "Nelson J Obus" with address state NY, is listed on 48 filings — most recently by WYNNEFIELD PARTNERS SMALL CAP VALUE LP I (Sep 25, 2026). Both records have filings in the same period (Feb 19, 2015).

Same name, different state: "Nelson Obus" (CA) is a separate record

This page covers filings where the address state is TX. A separate record, "Nelson Obus" with address state CA, is listed on 2 filings — most recently by LANDEC CORP \CA\ (Dec 6, 2018). The two records do not overlap in time: this page has one filing dated Feb 19, 2015; the other runs Feb 22, 2016 to Dec 6, 2018.

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.

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 every filing this person is listed on (latest filing per offering, per issuer).
