Transaction Materiality

This filing does not report a financial transaction; therefore, metrics such as transaction value and percentage of market cap are not applicable.

Impact Evaluation

• Market Cap Context: As a non-financial corporate governance announcement, this event does not directly impact Cognex's $6.94 billion market capitalization.
• Significance: The significance is low. The key detail for investors is the confirmation that there were no disagreements or reportable events with the outgoing auditor, which mitigates concerns typically associated with an auditor change.
