Key records

The five facts investors ask about first. Each section states what was searched and when. Items still in human review are not shown.

1. Lawsuits

None found in sources searched.

Sources searched: CourtListener bulk data (RECAP dockets as of 2026-09-30) — federal district + bankruptcy courts; live RECAP re-check pending. State courts: not yet searched. PACER: not searched. · Last checked Oct 24, 2026, 12:29 AM ET.

State courts: not yet searched. No state offers a lawful automated statewide source PartnerFacts can use today. Texas (re:SearchTX) terms prohibit storing results in a database open to third parties; New York (WebCivil) and Massachusetts (MassCourts) require a browser check that blocks scripted queries; California has no statewide index (58 county portals; Rule of Court 2.503 grants name-based access case by case); Florida, Utah and Illinois offer paid or partial access whose terms for automated use are unverified. Washington (dw.courts.wa.gov; bulk index reports under a JISC data-dissemination agreement), Delaware (CourtConnect; Court of Chancery not included) and Arizona (apps.azcourts.gov/publicaccess, which has an official channel to request high-volume access) are the candidates; PartnerFacts will request written permission before any automated search. Federal courts are searched through CourtListener / RECAP.

2. Regulatory actions

SEC enforcement searched: SEC litigation releases and administrative proceedings — respondent names in the sec.gov index titles (30,205 releases, 1995-09-19 to 2026-10-23); release text is read only to confirm a candidate.

4. Differences between public sources

As reported by the issuer on Form D (Items 12–15), 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 all 15 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
