Impact Evaluation

• Market Cap Context: With a market capitalization of $60 million, the $47k sale is financially immaterial, representing less than 0.1% of the company's value.
• Ownership Concentration: The insider sold approximately 28% of her holdings reported in this filing. While a notable percentage of her personal stake, the absolute value is small.
• Transaction Significance: The transaction is rated as having low significance due to its small value relative to the company's market cap and its execution under a pre-scheduled 10b5-1 plan, which decouples it from immediate corporate developments.

Additional Context

Special Circumstances

• The sales were executed pursuant to a Rule 10b5-1 trading plan adopted by the insider on August 27, 2025. Such plans are established in advance to automatically execute trades, mitigating accusations of trading on non-public information.
