Rosa David A 4

What Happened

• David A. Rosa, CEO, President and a director of NeuroOne Medical Technologies Corp (NMTC), had 71,325 shares disposed on February 18, 2026 to cover a tax liability (transaction code F). The shares were valued at $0.68 each, for a total of approximately $48,501.
• This was a share-for-tax withholding (not an open-market sale), a common administrative step following an option exercise or award vesting and not necessarily a signal of buying or selling for investment reasons.

Key Details

• Transaction date: 2026-02-18; price per share: $0.68; total value: ~$48,501.
• Transaction type: F — payment of exercise price or tax liability (shares withheld to satisfy taxes).
• Shares owned after the transaction: not disclosed in the filed Form 4.
• Filing date / timeliness: Form filed 2026-02-20 — appears timely (Form 4s are typically due within two business days).
• No 10b5-1 plan or other special footnotes reported in the provided transaction details.

Context

• When insiders exercise options or receive restricted shares, companies often withhold a portion of the resulting shares to cover taxes (a "share withholding" or "cashless" tax payment). That administrative action reduces the insider’s reported share count but is different from an open-market sale for cash.
• Such withholdings are routine and should be interpreted as a tax-related adjustment unless the filing shows additional open-market sales or purchases.
