Rosa David A 4

What Happened

• David A. Rosa, CEO, President and Director of NeuroOne Medical Technologies Corp (NMTC), disposed of 2,458 shares on 2026-03-31. The filing reports the shares were surrendered at $0.78 per share for a total of $1,910 to satisfy a tax withholding or exercise payment obligation (transaction code F). This is a withholding/tax-related disposition rather than an open-market sale.

Key Details

• Transaction date: 2026-03-31; Filing date (Form 4): 2026-04-01 (timely).
• Shares disposed: 2,458 at $0.78 per share; total value reported: $1,910.
• Transaction code: F — payment of exercise price or tax liability (typically shares surrendered to cover withholding).
• Shares owned after the transaction: not specified in the summary data of the filing.
• This is not reported as a market sale (code S) and appears routine for tax withholding after an equity event.

Context

• For retail investors: disposals under code F usually reflect tax withholding after an option exercise or vesting and do not necessarily signal a change in the insider’s view of the company. The cash value involved here is small (~$1.9K) relative to typical insider trades.
