The short version

Thomas Iannarone is listed as an executive officer on 66 SEC Form D filings by 43 issuers between Jun 2013 and Jun 2025. Largest by amount reported sold: GSO Capital Solutions Overseas Feeder Fund III L.P. (New York, NY — pooled investment fund — 2017–2018; $7.12B reported sold to 69 investors), GSO Capital Solutions Fund III LP (New York, NY — pooled investment fund — 2017–2018; $7.12B reported sold to 70 investors), GSO European Senior Debt Feeder Fund LP (New York, NY — pooled investment fund — 2014–2015; $1.5B reported sold to 40 investors), GSO ENERGY PARTNERS-A LP (New York, NY — pooled investment fund — 2015; $650M reported sold to 1 investors), GSO Direct Lending Fund-D LP (New York, NY — pooled investment fund — 2018–2019; $625M reported sold to 1 investors) and 38 more (all listed below).

What this means That is a lot of deals — 43 separate companies raised money with this person listed as executive officer, over about 12 years. Across those companies the filings report $21.44B sold in total.

Listed alongside Marisa Beeney (66 shared filings), John G. Finley (42 shared filings), Bennett J. Goodman (39 shared filings), Stephen A. Schwarzman (39 shared filings), Hamilton E. James (36 shared filings) and 72 others.

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

All 43 issuers belong to the sponsor group Blackstone (774 issuers, $1033.12B reported sold, 2009–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Blackstone has 774 companies on file and $1033.12B 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, 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) — 1 court case matching the name, 1 bankruptcy case matching the name listed in Key records below.

What this means 2 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 the newest 50 of 66 public filings for Thomas Iannarone and found 8 differences, 1 worth asking the sponsor about: 6 paid sellers are listed without a CRD number; 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: "Thomas Iannarone" (L2) is a separate record

This page covers filings where the address state is NY. A separate record, "Thomas Iannarone" with address state L2, is listed on 50 filings — most recently by Blackstone European Senior Loan Fund (Jan 9, 2024). Both records have filings in the same period (May 19, 2015 to Jan 9, 2024).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. 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. We compared the newest 50 of 66 filings (work cap); older filings are not covered here. 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).

Deals 43

Every issuer that named Thomas Iannarone on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.

Same business address

51 other issuers file from the same address (first 50 shown)

A shared address can mean the same team, a shared office building or a registered agent. It is a lead, not a conclusion.

Registrations and other filings

Business registration (state registry / Secretary of State)

Individuals are not matched to business registrations — registries list companies, and a name alone is not enough to tie a person to one. Officers and managers appear by name inside each matched company's record on the issuer pages. Registries searched: AL (Alabama Secretary of State — Business Entity Records (arc-sos.state.al.us), searched by issuer name, data as of Oct 24, 2026); CO (Colorado Secretary of State — Business Entities in Colorado (data.colorado.gov), data as of Oct 23, 2026); CT (Connecticut Secretary of the State — Business Registry (data.ct.gov), data as of Oct 24, 2026); FL (Florida Department of State, Division of Corporations — quarterly corporate data file (Sunbiz), data as of Oct 7, 2026); KY (Kentucky Secretary of State — Business Entity Search (sosbes.sos.ky.gov), searched by issuer name, data as of Oct 24, 2026); NY (New York Department of State — Corporations and Other Entities (data.ny.gov: All Filings + Active Corporations), data as of Oct 20, 2026); OR (Oregon Secretary of State — Active Businesses, All (data.oregon.gov), data as of Oct 20, 2026); PA (Pennsylvania Department of State — Registered Businesses, Current (data.pa.gov), data as of Oct 6, 2026); TX (Texas Comptroller — Active Franchise Taxpayers incl. Secretary of State file data (data.texas.gov), data as of Oct 24, 2026). Registries of other states have not been searched: many publish no bulk file and require a CAPTCHA or bot challenge on their search page, which we do not bypass (Delaware, for example, offers no public bulk file).

Adviser registration (Form ADV)

A person is never an adviser firm. 13 of the 43 issuers this person is listed on match a Form ADV adviser (searched 24,962 advisers as of Oct 2, 2026): Blackstone CLO Mezzanine Fund LP, Blackstone Secured Trust Feeder LP, Blackstone Senior Floating Rate Opportunity Feeder Fund LP, Blackstone Senior Floating Rate Opportunity Fund LP, Eastland Topco LP, Doncaster Topco LP, Cambridge Topco LP, Blackstone Rated Senior Direct Lending Fund LP, Berlin Topco LP, Akron Topco LP, GSO Energy Partners-D LP, GSO European Senior Debt Fund LP, GSO European Senior Debt Feeder Fund LP.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Thomas Iannarone by design. Searched property records in Hillsborough County FL (Clerk recorded-document index Oct 14, 2026 to Oct 15, 2026 + FL DOR 2026 ownership roll), Miami-Dade County FL (FL DOR 2026 ownership roll), Harris County TX (HCAD 2026 ownership roll), Dallas County TX (DCAD 2026 ownership roll), New York City ACRIS documents and PLUTO ownership rows already retrieved for other issuers, Cook County IL sale and ownership rows already retrieved for other issuers (814,874 records as of Oct 23, 2026, 8:59 PM ET) for the 43 issuers this person is listed on — nothing matched.
