NNE CEO Walker sells 123,688 shares for $3.3M via 8 scheduled transactions at $26.49 avg; stock now -61.3% from 52-week high

James John Walker, Chief Executive Officer of Nano Nuclear Energy Inc., executed 8 separate sales totaling 123,688 shares for $3,276,422.87 on 2026-06-03, reducing his non-derivative holdings from 678.7K to 555.0K shares (-18.2%). This sale is part of a pre-arranged 10b5-1 trading plan and therefore scheduled rather than discretionary. The stock has declined -61.3% from its 52-week high of $60.87 and currently trades at $23.56, well below the blended average price of $26.49 at which Walker executed these sales. His prior sales at NNE have been followed by significant declines: five prior sales on 2026-01-28 showed 30-day returns ranging from -24.6% to -21.0% and 90-day returns from -32.8% to -29.5%. The company is unprofitable (net income $-9.2M in the most recent fiscal year), which adds material context to this transaction, though Walker retains 576,398 shares through derivative holdings (stock options and restricted stock units).

NNE President Jiang Yu sold 745,900 shares for $19.9M via 10b5-1 plan; stock down 61.3% from 52-week high.

On 2026-06-03, Jiang Yu (President and Chairman) executed 15 separate sales totaling 745,900 shares for $19,896,984.50 at prices ranging from $26.29 to $29.91, reducing his non-derivative holdings from 8,969,900 shares to 8,224,000 shares (-8.3%). This sale is part of a pre-arranged 10b5-1 trading plan and therefore scheduled rather than discretionary. The broader context shows the stock is currently trading at $23.56, down 61.3% from its 52-week high of $60.87 and down 19.0% over the past 30 days, significantly below the blended average price of $26.68 at which these shares were sold. Yu's cross-ticker track record shows an average 90-day return of -29.8% after his 16 prior open-market sells, while his same-ticker history at NNE shows consistently negative 30-day and 90-day performance following his five prior sales in January 2026 (ranging from -13.6% to -24.6% at 30 days). The company remains unprofitable with a net income of $-9,180,166.00 in its most recent full fiscal year, adding fundamental uncertainty to the trading environment.

CFO Jaisun Garcha sells 37,215 shares at blended $26.48 for $985,617.05 under 10b5-1 plan; stock down -61.3% from 52-week high

Jaisun Garcha, CFO of Nano Nuclear Energy Inc., executed 5 separate sales totaling 37,215 shares for $985,617.05 on 2026-06-03 under a pre-arranged 10b5-1 trading plan, reducing non-derivative holdings from 382,215 to 345,000 shares (-9.7%). The company reported a full-year net income of $-9,180,166.00, indicating unprofitable operations, while the stock has declined -61.3% from its 52-week high of $60.87 and trades at $23.56 versus the blended sale price of $26.48. His prior sales at NNE (3 prior trades on 2026-01-28) saw 30-day declines ranging from -21.0% to -24.5% and 90-day declines ranging from -29.6% to -32.7%, establishing a pattern of downward momentum following his stock sales at this ticker. The scheduled nature of this 10b5-1 transaction means timing reflects pre-established plan mechanics rather than discretionary decision-making; however, the combination of unprofitability, significant price depreciation since sale execution, and consistent post-sale weakness in his prior same-ticker sales warrants investor attention to fundamental performance and near-term stock dynamics.
