Impact Evaluation

• Ownership Concentration: The sale represents less than 1% of the director's total holdings (direct and indirect). His post-transaction ownership of 106,664 shares remains a small stake (less than 0.1%) of the total shares outstanding.
• Transaction Significance: The sale is objectively low in significance. Both the value as a percentage of market cap (0.00095%) and the shares as a percentage of outstanding shares (0.00090%) are well below the thresholds for moderate or high significance.
