• Footnote F1: The direct shares were acquired from the issuer under a Subscription Agreement dated March 9, 2026.
• Footnote F3: The 242,945 derivative shares are pre-funded warrants exercisable any time, subject to an ownership cap that generally prevents exercise if it would push holdings above 9.99% of outstanding shares (holder may elect 61 days’ notice to increase cap up to 19.99%).

Context

• The derivative portion represents pre-funded warrants (not a sale); these can be exercised into common stock but include an ownership cap to limit immediate voting/ownership concentration.
• This is an institutional/large-holder purchase (10% owner), not an executive’s personal trade; such buys can indicate institutional commitment but should be considered alongside other data (SEC filings, company news, financials).
• No indication in the filing of immediate resale (cashless exercise) or tax-related transfers.
