The short version

Peter Haskopoulos is listed as a director on 20 SEC Form D filings by 19 issuers between May 2015 and Sep 2023. Largest by amount reported sold: Riverstone Echo Continuation Fund, L.P. (New York, NY — pooled investment fund — 2020; $988.5M reported sold to 40 investors), Riverstone Non-ECI Partners, L.P. (New York, NY — pooled investment fund — 2015–2016; $256.3M reported sold to 7 investors), Riverstone Grizzly Feeder Fund, L.P. (Toronto, Ontario, Canada (as filed: A6) — pooled investment fund — 2023), Riverstone Grizzly Continuation Coinvestment, L.P. (New York, NY — pooled investment fund — 2023), Riverstone Grizzly Continuation Fund, L.P. (New York, NY — pooled investment fund — 2023) and 14 more (all listed below).

What this means That is a lot of deals — 19 separate companies raised money with this person listed as director, over about 8 years. Across those companies the filings report $1.24B sold in total.

Listed alongside Riverstone Holdings LLC (18 shared filings, management entity), David M. Leuschen (17 shared filings), Pierre F. Lapeyre, Jr. (17 shared filings), Riverstone Investment Group LLC (15 shared filings, management entity), Riverstone ECF GP, LLC (3 shared filings, management entity) and 20 others.

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

The issuers belong to 2 sponsor groups: Riverstone Bison (13 issuers, $988.5M reported sold, 2020–2023) and Riverstone (29 issuers, $12.42B reported sold, 2012–2020).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

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) — none found.

What this means Nothing turned up where we looked (3 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 20 public filings for Peter Haskopoulos and found 2 differences, 1 worth asking the sponsor about: Paid seller listed without a CRD number: Barak Capital Underwriting Ltd; 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

2 differences found between the filings for Peter Haskopoulos — 1 worth asking about (compared 20 filings on Oct 24, 2026)

Worth asking · Jul 7, 2016

Paid seller listed without a CRD number: Barak Capital Underwriting Ltd. — Riverstone Non-ECI Partners, L.P.

Barak Capital Underwriting Ltd. is listed as receiving sales compensation on 1 filing (Jul 7, 2016) with no FINRA CRD number given.

What this means People paid to sell securities normally hold a FINRA registration with a CRD number. Without one we cannot look them up on BrokerCheck. Ask who they are and whether they are registered.

Sources
Note · Jun 24, 2015 – Jul 7, 2016

No amendment in the last 12 months on an offering that may still be open — Riverstone Non-ECI Partners, L.P. (latest filing Jul 7, 2016)

The latest filing for this offering is dated Jul 7, 2016 (first sale Jun 24, 2015). It reports $256,250,000 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
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.

5. Money to insiders

7 of 19 offerings report sales commissions totalling $13,668,874; 0 report finder's fees; 0 report proceeds to related persons. (includes amounts the issuer reported as estimates)

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 19

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

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); 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. 14 of the 19 issuers this person is listed on match a Form ADV adviser (searched 24,962 advisers as of Oct 2, 2026): Riverstone Grizzly Feeder Fund, L.P., Riverstone Grizzly Continuation Fund, L.P., Riverstone Grizzly Continuation Coinvestment, L.P., Riverstone Nolan Continuation Fund, L.P., Riverstone Nolan Continuation Fund Parallel, L.P., Riverstone Nolan ASC Coinvestment, L.P., Riverstone Valor Upstream Co-Investment L.P., Riverstone Bison Continuation Coinvestment, L.P., Riverstone Bison Rollover Fund, L.P., Riverstone Bison Continuation Fund Parallel, L.P., Riverstone Bison Continuation Fund, L.P., Riverstone Echo Rollover Fund, L.P., Riverstone Echo Continuation Fund, L.P., Riverstone Non-ECI Partners, L.P..

Other offering types (Regulation A and Regulation Crowdfunding)

Searched SEC Regulation A Data Sets (Forms 1-A, 1-K, 1-Z; 2015 Q2 → 2026 Q3); SEC Crowdfunding Offerings Data Sets (Form C family; 2016 Q2 → 2026 Q3); EDGAR form index for 2026 Q3 → 2026 Q4 (51,358 records as of Oct 23, 2026, 8:41 PM ET) — nothing matched this name.

Property records none — individuals are not matched

Property records are matched to companies only, never to individuals, so none are matched to Peter Haskopoulos 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 19 issuers this person is listed on — nothing matched.
