The short version

Quantinuum is an other organized in Cayman Islands (formed 2021), based in Broomfield, CO.

What this means A deal company is usually set up for one investment; its Form D is the notice it files after selling to investors.

It has filed 3 Form D filings (2 originals, 1 amendment) for 2 offerings between Jan 2024 and Nov 2025. The latest filing of each offering reports a combined $890.8M sold of $912M offered to 56 investors; industry as reported: computers; latest exemption Rule 506(c).

What this means 2 separate raises over about 1 year. Amendments are routine updates (an ongoing raise must update its Form D at least once a year).

Key people as listed: Anne Madden (director), Avinash Palaniswamy (executive officer), Brian Sereda (executive officer), George Sherman (director), Gregory Lewis (director) and 11 more.

What this means These are the people the company itself named as running or promoting it. Tap a name to see every other deal they are on.

Reported money out: $13.4M in sales commissions (latest filing per offering). Paid to sell it: J.P. MORGAN SECURITIES LLC.

What this means $13.4M went to brokers for selling it (about 1.5% of what was sold).

Activity: 0 new offerings in the last 12 months; latest amendment Nov 14, 2025; latest filing Nov 14, 2025.

What this means No new raise filed in the past year — this deal company may be done raising, or simply quiet.

Searched SEC Form ADV bulk data (registered + exempt reporting advisers) (24,962 records as of Oct 2, 2026, 8:00 AM ET) — nothing matched Quantinuum.

State business registry: CO registry lists Quantinuum LLC as active ("Good Standing" as printed), formed Jun 18, 2021, registered agent CORPORATION SERVICE COMPANY.

What this means Formation date, status and registered agent as the state prints them; a registry listing says nothing about the offering itself.

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. No completed search yet: property records (NYC, FL, IL and TX counties) (runs automatically; this line updates when it finishes).

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 3 public filings for Quantinuum and found 5 differences: Form D filed 16 days after the first sale; No amendment in the last 12 months on an offering that may still be open; 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.

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). A registry listing is the state's own record of the entity; it says nothing about the offering itself.

4. Differences between public sources

No comparisons published

What is compared

No public statement by this issuer has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this issuer yet.

5 differences found between the filings for Quantinuum (compared 3 filings on Oct 24, 2026)

Note · Dec 20, 2023 – Jan 5, 2024

Form D filed 16 days after the first sale — Quantinuum

The filing says the first sale was Dec 20, 2023. The Form D was filed Jan 5, 2024 — 16 days later. The rule: a Form D is generally due within 15 days after the first sale, so this one is 1 days past that.

What this means A late notice is common and carries no penalty by itself. It is worth asking the sponsor why the paperwork lagged.

Form D · Jan 5, 2024 ↗Quantinuum — PartnerFacts page ↗
Sources
Note · Dec 20, 2023 – Jan 5, 2024

No amendment in the last 12 months on an offering that may still be open — Quantinuum (latest filing Jan 5, 2024)

The latest filing for this offering is dated Jan 5, 2024 (first sale Dec 20, 2023). It reports $51,999,995 sold of $61,999,994 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.

Form D · Jan 5, 2024 ↗Quantinuum — PartnerFacts page ↗
Sources
Note · Jan 5, 2024 – Aug 25, 2025

Rajeeb Hazra's role changed at Quantinuum: executive officer, director → executive officer

The Jan 5, 2024 filing lists Rajeeb Hazra as executive officer, director; the Aug 25, 2025 Form D lists executive officer.

What this means Roles on Form D are self-reported by the issuer. A change can mean a real change in who runs the company, or just a different box ticked. Ask who makes decisions today.

The Aug 25, 2025 filing says $750,000,000 offered; the Nov 14, 2025 Form D/A says $850,000,000.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Address moved from Charlotte, NC to Broomfield, CO — Quantinuum

The people listed on the Jan 5, 2024 filing give Charlotte, NC; on the Aug 25, 2025 filing they give Broomfield, CO.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

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.

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.

0 recorded documents and 0 ownership records matched to Quantinuum in the sources searched.
