Schedule 13G Filing – iOThree Limited (Ticker: IOTR)

The filing discloses the beneficial ownership of iOThree Limited’s ordinary shares (par value $0.00625) as of 30 June 2025. A total of 25,650,000 ordinary shares are stated as issued and outstanding. Three reporting persons cross-filed the statement:

  • Eng Chye Koh (Singapore citizen) – 19,209,600 shares, representing 74.89 % of the outstanding class, with sole voting and dispositive power.
  • iO3 Strategic Investments Ltd. (British Virgin Islands) – 14,282,400 shares, representing 55.68 %, with sole voting and dispositive power.
  • All Wealthy International Ltd. (British Virgin Islands) – 4,927,200 shares, representing 19.21 %, with sole voting and dispositive power.

The percentages are calculated by each filer against the same 25.65 million share base. Each filer certifies no shared voting or dispositive authority. The reporting persons have executed a joint filing agreement (Exhibit 1) and attest that the information is true, complete and correct as of the signature date, 15 July 2025.

Key observations for investors:

  • Eng Chye Koh alone exceeds the 50 % threshold, implying effective control of corporate actions requiring shareholder approval.
  • Two British Virgin Islands entities—likely investment vehicles—also cross the 5 % reporting threshold, further concentrating ownership.
  • Because the combined disclosed stakes are well above 80 % of total shares, the effective public float appears limited, which may affect trading liquidity and governance dynamics.

Deposito Schedule 13G – iOThree Limited (Ticker: IOTR)

Il deposito rivela la proprietà effettiva delle azioni ordinarie di iOThree Limited (valore nominale $0,00625) al 30 giugno 2025. Sono dichiarate emesse e in circolazione un totale di 25.650.000 azioni ordinarie. Tre soggetti segnalanti hanno presentato congiuntamente la dichiarazione:

  • Eng Chye Koh (cittadino di Singapore) – 19.209.600 azioni, pari al 74,89% della classe in circolazione, con pieno potere di voto e disposizione.
  • iO3 Strategic Investments Ltd. (Isole Vergini Britanniche) – 14.282.400 azioni, pari al 55,68%, con pieno potere di voto e disposizione.
  • All Wealthy International Ltd. (Isole Vergini Britanniche) – 4.927.200 azioni, pari al 19,21%, con pieno potere di voto e disposizione.

Le percentuali sono calcolate da ciascun dichiarante sulla base delle 25,65 milioni di azioni. Ogni dichiarante certifica di non avere autorità condivisa di voto o disposizione. I soggetti segnalanti hanno sottoscritto un accordo di deposito congiunto (Allegato 1) e attestano che le informazioni sono vere, complete e corrette alla data di firma, 15 luglio 2025.

Osservazioni chiave per gli investitori:

  • Eng Chye Koh da solo supera la soglia del 50%, implicando un controllo effettivo sulle decisioni societarie che richiedono l'approvazione degli azionisti.
  • Due entità delle Isole Vergini Britanniche – presumibilmente veicoli d'investimento – superano anch'esse la soglia di segnalazione del 5%, concentrando ulteriormente la proprietà.
  • Poiché le partecipazioni dichiarate complessivamente superano l'80% delle azioni totali, il flottante effettivo al pubblico appare limitato, il che potrebbe influire sulla liquidità di mercato e sulle dinamiche di governance.

Observaciones clave para inversores:

  • Eng Chye Koh por sí solo supera el umbral del 50%, lo que implica un control efectivo de las acciones corporativas que requieren aprobación de los accionistas.
  • Dos entidades de las Islas Vírgenes Británicas – probablemente vehículos de inversión – también superan el umbral de reporte del 5%, concentrando aún más la propiedad.
  • Dado que las participaciones combinadas declaradas superan ampliamente el 80% del total de acciones, el flotante público efectivo parece limitado, lo que puede afectar la liquidez comercial y la dinámica de gobernanza.

Schedule 13G 제출 – iOThree Limited (티커: IOTR)

본 제출서는 2025년 6월 30일 기준 iOThree Limited의 보통주(액면가 $0.00625)의 실질 소유 현황을 공개합니다. 총 25,650,000주의 보통주가 발행 및 유통 중임이 명시되어 있습니다. 세 명의 보고자가 공동으로 제출하였습니다:

  • Eng Chye Koh (싱가포르 시민) – 19,209,600주, 유통 주식의 74.89%에 해당하며, 단독 의결권 및 처분권 보유.
  • iO3 Strategic Investments Ltd. (영국령 버진아일랜드) – 14,282,400주, 55.68% 보유, 단독 의결권 및 처분권 보유.
  • All Wealthy International Ltd. (영국령 버진아일랜드) – 4,927,200주, 19.21% 보유, 단독 의결권 및 처분권 보유.

비율은 각 제출자가 동일한 2,565만 주를 기준으로 산출했습니다. 각 제출자는 의결권 또는 처분권을 공유하지 않음을 인증합니다. 보고자들은 공동 제출 계약서(부속서 1)를 체결했으며, 2025년 7월 15일 서명일 현재 정보가 진실되고 완전하며 정확함을 확인합니다.

투자자를 위한 주요 관찰 사항:

  • Eng Chye Koh 단독으로 50% 기준을 초과하여 주주 승인 필요한 기업 행위에 대한 실질적 통제권을 가짐.
  • 영국령 버진아일랜드 소재 두 투자법인이 5% 보고 기준을 넘으며 소유권 집중이 심화됨.
  • 공개된 지분 합계가 총 주식의 80%를 훨씬 넘기 때문에 실질적인 공중 유통 주식 수가 제한적이며, 이는 거래 유동성과 지배구조에 영향을 미칠 수 있음.

Le dépôt révèle la propriété bénéficiaire des actions ordinaires d’iOThree Limited (valeur nominale de 0,00625 $) au 30 juin 2025. Un total de 25 650 000 actions ordinaires sont émises et en circulation. Trois déclarants ont déposé conjointement la déclaration :

  • Eng Chye Koh (citoyen de Singapour) – 19 209 600 actions, représentant 74,89 % de la catégorie en circulation, avec un pouvoir exclusif de vote et de disposition.
  • iO3 Strategic Investments Ltd. (Îles Vierges britanniques) – 14 282 400 actions, représentant 55,68 %, avec un pouvoir exclusif de vote et de disposition.

Les déclarants ont signé un accord de dépôt conjoint (Annexe 1) et attestent que les informations sont vraies, complètes et exactes à la date de signature, le 15 juillet 2025.

Points clés pour les investisseurs :

  • Eng Chye Koh dépasse à lui seul le seuil de 50 %, ce qui implique un contrôle effectif des actions nécessitant l’approbation des actionnaires.
  • Deux entités des Îles Vierges britanniques – probablement des véhicules d’investissement – dépassent également le seuil de déclaration de 5 %, concentrant davantage la propriété.
  • Étant donné que les participations combinées déclarées dépassent largement 80 % du total des actions, le flottant public effectif semble limité, ce qui pourrait affecter la liquidité des échanges et la dynamique de gouvernance.

Schedule 13G Einreichung – iOThree Limited (Ticker: IOTR)

Die Einreichung offenbart den wirtschaftlichen Eigentümer der Stammaktien von iOThree Limited (Nennwert $0,00625) zum 30. Juni 2025. Insgesamt werden 25.650.000 ausgegebene und ausstehende Stammaktien angegeben. Drei meldende Personen reichten die Erklärung gemeinsam ein:

  • Eng Chye Koh (Staatsbürger von Singapur) – 19.209.600 Aktien, entsprechend 74,89 % der ausstehenden Aktienklasse, mit alleinigem Stimm- und Verfügungsrecht.
  • iO3 Strategic Investments Ltd. (Britische Jungferninseln) – 14.282.400 Aktien, entsprechend 55,68 %, mit alleinigem Stimm- und Verfügungsrecht.
  • All Wealthy International Ltd. (Britische Jungferninseln) – 4.927.200 Aktien, entsprechend 19,21 %, mit alleinigem Stimm- und Verfügungsrecht.

Die Prozentsätze wurden von jedem Melder auf derselben Basis von 25,65 Millionen Aktien berechnet. Jeder Melder bestätigt, keine geteilte Stimm- oder Verfügungsbefugnis zu haben. Die meldenden Personen haben eine gemeinsame Einreichungsvereinbarung (Anlage 1) unterzeichnet und bestätigen, dass die Angaben zum Unterschriftsdatum, dem 15. Juli 2025, wahr, vollständig und korrekt sind.

Wesentliche Beobachtungen für Investoren:

  • Eng Chye Koh überschreitet allein die 50 %-Schwelle, was auf eine effektive Kontrolle über unternehmensbezogene Maßnahmen mit Aktionärszustimmung hinweist.
  • Zwei Gesellschaften der Britischen Jungferninseln – vermutlich Investmentvehikel – überschreiten ebenfalls die Meldepflicht von 5 %, was die Eigentümerschaft weiter konzentriert.
  • Da die zusammengefassten gemeldeten Anteile deutlich über 80 % der Gesamtaktien liegen, erscheint der effektive Streubesitz begrenzt, was die Handelsliquidität und Governance-Dynamik beeinflussen könnte.
Positive
  • High insider commitment: Eng Chye Koh’s 74.89 % stake indicates strong alignment with the company’s long-term performance.
Negative
  • Concentrated control: A single shareholder can unilaterally dictate corporate actions, reducing minority influence.
  • Limited public float: With over 80 % of shares in insider hands, trading liquidity and index eligibility may be constrained.

Insights

TL;DR: Filing confirms overwhelming insider control (75 %) by Eng Chye Koh; float is small, liquidity and governance minority risk rise.

This Schedule 13G shows that Eng Chye Koh controls roughly three-quarters of iOThree’s outstanding shares, granting him near-absolute authority over shareholder votes, director elections and strategic decisions. Two affiliated BVI companies also individually exceed 5 %, reinforcing concentrated ownership. While such alignment can signal strong founder commitment, it simultaneously limits the influence of minority shareholders and may reduce free float, potentially increasing share-price volatility and limiting institutional participation. Because no financial results are provided, the main investment takeaway is structural rather than operational. Overall impact is material, as control dynamics are a key valuation input for small-cap issuers.

TL;DR: Majority control triggers governance red flags; minority protections crucial.

The 13G highlights a classical controlled-company setup. With 74.89 % ownership and sole voting power, Eng Chye Koh can pass ordinary and special resolutions unilaterally. The BVI entities, each above 5 %, might be related, but the filing does not clarify this. Investors should recognize that board independence, related-party transactions and takeover defenses could be influenced by the controlling shareholder. Limited public float (<20 % by implication) may also affect listing-standard exemptions. While not inherently negative, these facts are materially relevant for governance-risk assessment.
