Nano Nuclear Energy (NNE) CEO Walker Exercises 200,000 Options

What Happened

(NNE), exercised 200,000 stock options on June 3, 2026 at an exercise price of $3.00 per share, paying $600,000 and receiving 200,000 common shares. The filing also reports the conversion/disposition of a related 200,000 derivative interest (reflecting the option-to-share conversion), not a market sale.

Key Details

• Transaction date: June 3, 2026.
• Exercise: 200,000 options exercised at $3.00 per share = $600,000 cash paid; reported as Form 4 transaction code M (exercise/conversion).
• Derivative line: 200,000 shares listed at $0.00 under a derivative disposition entry — represents the conversion of the options into shares (not a sale).
• Holdings after transaction (per amended filing): 685,000 shares of common stock and 300,000 options outstanding.

  • F2/F4: This Form 4/A amends the June 5, 2026 filing to correct reported columns and holdings; F2 notes the amended counts do not reflect subsequent sales of 123,688 shares reported in the original June 5 filing.

Context

• This was an option exercise (insider converting options into shares) and not an open-market sale; Walker acquired shares by paying the exercise price rather than selling immediately (no cashless exercise indicated).
• Such exercises are common for executives approaching option expiration or managing equity holdings. This report is factual disclosure of the exercise and updated holdings; it does not state management intent or future company prospects.
