Impact Evaluation

• Market Cap Context: The Eastern Co. is a micro-cap company with a market capitalization of $120 million. The $49k transaction is negligible in this context.
• Ownership Concentration: The reporting group, including James A. Mitarotonda, holds a significant position of over 11% of all outstanding shares. This purchase is a very small addition to that stake.
• Transaction Significance: The transaction represents less than 0.05% of both the market cap and shares outstanding, falling well below the thresholds for moderate or high significance.
