NNE Nano Nuclear Energy Inc. Insider Trading

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

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.

I Financial Ventures Group LLC, a 10% owner, executed 10 scheduled sales totaling 700,000 shares for $18,674,130.60 across a narrow price range ($26.30–$29.91), reducing holdings to 8,224,000 shares. The transaction was conducted under a pre-arranged 10b5-1 trading plan, meaning execution was scheduled rather than discretionary. Context: the company posted net income of $-9,180,166.00 for its most recent full fiscal year, and the stock now trades at $23.56, down 19.0% over 30 days and 61.3% from the 52-week high of $60.87.

NNE President Yu Jiang sells 888,000 shares for $30.0M under pre-arranged 10b5-1 plan (Jan 28-29)

Yu Jiang executed 10 separate sales totaling 888,000 shares for $30,033,600.91 across two trading days at prices ranging from $30.76 to $35.25, reducing his holdings from 9,612,000 shares to 8,724,000 shares (-9.2%). This activity is part of a pre-arranged 10b5-1 trading plan, making it scheduled rather than discretionary. The multi-tranche execution across two days at varying price levels reflects the mechanical nature of Rule 10b5-1 compliance, not market timing. Without additional context on the plan's adoption date, terms, or peer insider activity, the sale itself represents a material reduction in the President and Chairman's equity stake, but the scheduled framework limits inference about forward-looking conviction or concern.

As a scheduled disposition under a 10b5-1 plan, this transaction reflects predetermined trading parameters rather than real-time market judgments by the insider.

10% Owner I Financial Ventures sold 888,000 shares for $30.0M (Jan 28-29, 2026) via 10b5-1 plan

I Financial Ventures Group LLC, a 10% owner of Nano Nuclear Energy Inc., executed 10 separate sales totaling 888,000 shares for $30,033,600.91 across January 28-29, 2026, reducing holdings from 9,612,000 to 8,724,000 shares. This transaction is part of a pre-arranged 10b5-1 trading plan and therefore represents a scheduled, non-discretionary disposal rather than a discretionary strategic choice. The multi-day, multi-price execution (ranging from $30.76 to $35.25) reflects programmatic liquidation under an established plan, not market-driven decision-making by the insider.
