The short version

Michael Costello is listed as an executive officer on 1 SEC Form D filing by 1 issuer in Aug 2026: WRM Wastewater TopCo, LP (New York, NY — environmental services — 2026; $571K reported sold to 8 investors).

What this means One deal on file with the SEC, filed Aug 2026. 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 Edward Hickman (1 shared filing), JAMES DEVLIN (1 shared filing), Oliver Noble (1 shared filing), Ross M. Posner (1 shared filing), Ryan Stewart (1 shared filing) and 1 others.

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

The issuer belongs to the sponsor group Ridgewood Energy (19 issuers, $4.63B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Ridgewood Energy has 19 companies on file and $4.63B 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, 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) — 8 bankruptcy cases matching the name listed in Key records below.

What this means 8 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 Michael Costello and found 4 differences: Same name, different state: "Michael J. Costello" (MA) is a separate record; Same name, different state: "Michael A. Costello" (MI or WI or CA or FL or ND) is a separate record; 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.

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.
