The short version

Wynnchurch is a sponsor group of 9 issuers that PartnerFacts links to one sponsor (shared people, same business address, similar issuer names; automatic match from the filings), filing 12 Form D filings between Mar 2009 and Dec 2023.

What this means One team, 9 deal companies, about 14 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: $2.55B to 213 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (6), Manufacturing (2), "Other" (1). Issuers are based in IL (9).

What this means $2.55B raised across the group, about $12M per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: John A. Hatherly (9 issuers, executive officer, director, and promoter), Frank G. Hayes (6 issuers, executive officer, director, and promoter), Terry Theodore (5 issuers, executive officer, director, and promoter), Christopher P. O'brien (2 issuers, executive officer and director), ROY E. Sroka (2 issuers, executive officer) and 14 more.

What this means 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 Dec 8, 2023.

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

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), property records (NYC, FL, IL and TX counties) — 23 court cases matching the name, 5 bankruptcy cases matching the name listed in Key records below.

What this means 28 records came back, including 7 court cases still open — open cases can take years and cost money. 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 12 public filings for Wynnchurch and found 12 differences, 3 worth asking the sponsor about: 29% of the money raised went to insiders; Wynnchurch includes 4 deals that stopped filing before reaching their target; 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.
