Chairman Ronald Hafner has filed a Schedule 13D disclosing beneficial ownership of 557,131 common shares, equal to 13.2 % of the company鈥檚 4,097,641 outstanding shares. Mr. Hafner possesses sole voting and dispositive power over the entire position; no shares are held jointly.

Capital deployment was entirely from personal funds. The filing details multiple transactions that built the position:

Equity Purchase Agreement (10-Oct-2024): acquired 100,807 common shares plus 100,807 five-year warrants (exercise $4.25) at a combined price of $3.97.
Warrant Amendment (9-Oct-2024): received pre-funded warrants for 1,925 shares, exercisable at CHF 0.80.

For investors, the filing signals material insider confidence and establishes Mr. Hafner as the company鈥檚 largest known shareholder, potentially aligning board decisions with shareholder value creation. No immediate dilution or earnings impact is indicated, but future conversions of preferred shares and warrant exercises could expand the float.

La inversi贸n de capital provino 铆ntegramente de fondos personales. La presentaci贸n detalla m煤ltiples transacciones que conformaron la posici贸n:

Los acuerdos otorgan derechos de participaci贸n limitados (hasta el 50% de futuras ofertas durante un a帽o) pero no imponen convenios de voto. No se reportan procesos penales o civiles contra el declarante.

Para los inversores, la presentaci贸n se帽ala una confianza interna material y establece al Sr. Hafner como el mayor accionista conocido de la empresa, lo que podr铆a alinear las decisiones del consejo con la creaci贸n de valor para los accionistas. No se indica diluci贸n o impacto en ganancias inmediato, pero futuras conversiones de acciones preferentes y ejercicios de warrants podr铆an ampliar el flotante.

Le d茅ploiement de capital provient enti猫rement de fonds personnels. Le d茅p么t d茅taille plusieurs transactions ayant constitu茅 la position :

Pour les investisseurs, ce d茅p么t signale une confiance interne significative et 茅tablit M.

NLS Pharmaceutics Ltd. 鈥� Schedule 13D Einreichung (NLSPW)

Vorsitzender Ronald Hafner hat ein Schedule 13D eingereicht, das den wirtschaftlichen Eigentum von 557.131 Stammaktien offenlegt, was 13,2 % der 4.097.641 ausstehenden Aktien des Unternehmens entspricht. Herr Hafner besitzt alleinige Stimm- und Verf眉gungsgewalt 眉ber die gesamte Position; keine Aktien werden gemeinsam gehalten.

Die Kapitalbereitstellung erfolgte vollst盲ndig aus eigenen Mitteln. Die Einreichung beschreibt mehrere Transaktionen, die die Position aufgebaut haben:

Aktienkaufvertrag (10. Okt. 2024): Erwerb von 100.807 Stammaktien plus 100.807 f眉nfj盲hrige Warrants (Aus眉bungspreis $4,25) zu einem Gesamtpreis von $3,97.
Warrant-脛nderung (9. Okt. 2024): Erhalt von vorfinanzierten Warrants f眉r 1.925 Aktien, aus眉bbar zu CHF 0,80.
Schuldenkaufvertrag (10. Okt. 2024): Erhalt von 173.173 wandelbaren Vorzugsaktien (Umwandlungspreis $4,96) im Rahmen einer $4 Mio. Schuldenrestrukturierung.
Put-Call-Vereinbarung (Feb. 2025): Aus眉bung einer Option mit Kauf von 37.783 Vorzugsaktien f眉r $150.000.
Schuldenbegleichungen: 脺bertragung von 111.637 Stammaktien vom CEO Alexander Zwyer (7. Feb. 2025) und 17.782 Aktien von Magnetic Rock Investment AG (21. Feb. 2025).

Absicht: Die Aktien werden zu Investitionszwecken gehalten; keine aktivistische Agenda wird offengelegt. Die Vereinbarungen gew盲hren begrenzte Teilnahmerechte (bis zu 50 % zuk眉nftiger Angebote f眉r ein Jahr), legen jedoch keine Stimmrechtsvereinbarungen fest. Es sind keine straf- oder zivilrechtlichen Verfahren gegen den Einreicher bekannt.

F眉r Investoren signalisiert die Einreichung erhebliche Insider-Vertrauensw眉rdigkeit und etabliert Herrn Hafner als den gr枚脽ten bekannten Aktion盲r des Unternehmens, was potenziell die Vorstandsentscheidungen mit der Wertschaffung f眉r Aktion盲re in Einklang bringt. Es wird keine unmittelbare Verw盲sserung oder Gewinnwirkung angegeben, aber zuk眉nftige Umwandlungen von Vorzugsaktien und die Aus眉bung von Warrants k枚nnten den Streubesitz erh枚hen.

Positive

Insider ownership rises to 13.2 %, reflecting strong commitment by the chairman.
Purchases funded with personal capital, reducing reliance on company resources.
Participation in private placement and debt conversion infused new cash into NLS Pharmaceutics.
Sole voting power avoids complex shareholder group structures.

Negative

Outstanding warrants and convertible preferred shares introduce potential future dilution.

Insights

TL;DR: Chairman buys to 13.2 %; insider confidence, future dilution risk moderate.

Mr. Hafner鈥檚 accumulation to a >13 % stake represents a significant vote of confidence. Cash purchases, participation in the 2024 private placement and debt conversion show willingness to inject capital on market-based terms. Warrants and preferred shares, however, add potential future dilution of ~6鈥�8 % if fully converted/exercised. No immediate control change is signalled, and the filing is routine disclosure. Overall impact is incrementally positive for sentiment, neutral for near-term fundamentals.

TL;DR: Large insider stake strengthens alignment; activism unlikely.

The chairman鈥檚 13.2 % holding enhances board-shareholder alignment and reduces agency risk. Because voting power is sole, no group formation issues arise under Section 13(d). The participation rights in future offerings are time-limited and do not restrict other shareholders. Absence of activist language or takeover intent suggests governance status quo. Filing is governance-positive, though investors should monitor warrant and preferred conversions for dilution oversight.
