The short version

MARK A. TARINI is listed as an executive officer and director on 54 SEC Form D filings by 17 issuers between Oct 2010 and Dec 2025. Largest by amount reported sold: ArcLight Energy Partners Fund VI, L.P. (Boston, MA — pooled investment fund — 2014–2015; $5.58B reported sold to 206 investors), ArcLight Energy Partners Fund VII, L.P. (Boston, MA — pooled investment fund — 2018–2020; $3.38B reported sold to 74 investors), ARCLIGHT ENERGY PARTNERS FUND V, L.P. (Boston, MA — pooled investment fund — 2010–2011; $3.26B reported sold to 249 investors), ARCLIGHT INFRASTRUCTURE PARTNERS FUND VIII-A, L.P. (Boston, MA — pooled investment fund — 2023–2025; $2.83B reported sold to 39 investors), ARCLIGHT INFRASTRUCTURE PARTNERS FUND VIII-B, L.P. (Boston, MA — pooled investment fund — 2023–2025; $2.83B reported sold to 34 investors) and 12 more (all listed below).

What this means That is a lot of deals — 17 separate companies raised money with this person listed as executive officer and director, over about 15 years. Across those companies the filings report $26.27B sold in total.

Listed alongside DANIEL R. REVERS (54 shared filings), JOHN F. ERHARD (44 shared filings), ROBERT M. TREVISANI (36 shared filings), KEVIN M. CROSBY (28 shared filings), THEODORE D. BURKE (28 shared filings) and 14 others.

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

All 17 issuers belong to the sponsor group Arclight Infrastructure (23 issuers, $26.27B reported sold, 2010–2026).

What this means A sponsor group is one team that sets up a new company for each deal. Arclight Infrastructure has 23 companies on file and $26.27B 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) — 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 the newest 50 of 54 public filings for MARK A. TARINI and found 5 differences, 2 worth asking the sponsor about: 16 paid sellers are listed without a CRD number; MARK A. TARINI is no longer listed on the May 5, 2026 amendment; 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.

5 offerings have no amendment in the last 12 months and may still be open

No amendment in the last 12 months on an offering that may still be open — AL GCX Co-Invest, L.P.

(latest filing Aug 7, 2015) · No amendment in the last 12 months on an offering that may still be open — AEP Feeder Fund VI, Inc. (latest filing Aug 7, 2015)

MARK A. TARINI appears on the May 6, 2025 Form D (executive officer) but not on the May 5, 2026 Form D/A for the same offering.

What this means People leave, and the issuer must list only current officers, directors and promoters. It is still worth asking why this person left and who replaced them.

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 54 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 17

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

23 issuers · 61 filings · $26.27B reported sold · 2010–2026

One team, 23 deal companies. Mark A. Tarini is listed on 17 of them.

Sources

Issuers are grouped when their Form D filings share related persons, a management entity or a business address (automatic match from the filings). "Listed" marks the issuers that name MARK A. TARINI.

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)

None of the 17 issuers this person is listed on appears in Form ADV (searched 24,962 advisers as of Oct 2, 2026). A person is never an adviser firm; Form ADV is checked for the issuers and the management companies they are listed with.

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 MARK A. TARINI 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 17 issuers this person is listed on — nothing matched.
