Actionable Insight • Neutral

Monitor for any future Schedule 13G filing by Sagy, which would confirm full de-escalation. The passive stance and eligibility for 13G suggest no near-term activist pressure, but watch for any change in share count or issuer events that could alter Sagy's position.

Key Facts

  • Ami Sagy's beneficial ownership decreased to approximately 5.7% of ordinary shares as of September 30, 2026.
  • The decrease resulted from share issuances by the issuer, not from any sale or purchase by Sagy.
  • Sagy has not acquired or disposed of any ordinary shares since the prior amendment (November 28, 2025).
  • Sagy states he holds shares for investment purposes only and is eligible to report on Schedule 13G, signaling no activist intent.
  • The percentage is based on 2,866,715 ordinary shares outstanding, reflecting a 1-for-10 reverse share split effective September 4, 2026.
  • Sagy beneficially owns 163,709 ordinary shares directly.

Financial Impact

No financial impact; passive stake decrease due to issuer dilution, no transactions by the reporting person.

Risk Factors

  • Further dilution by the issuer could reduce Sagy's stake below 5%, triggering a potential exit or filing change.
  • Any future acquisition by Sagy could signal renewed interest, but current filing indicates no such plans.
