• Rule 10b5-1 Trading Plan: The option exercise and open-market sale were executed pursuant to a pre-arranged Rule 10b5-1 trading plan established on March 16, 2026.
• Remaining Holdings: Following these transactions, Cunningham directly retains 121,793 shares of common stock alongside 6,328 unexercised options in the reported derivative tranche.
• Market Impact: Given that the sale represented less than 2% of the insider's direct common stock position and was conducted pursuant to a standard 10b5-1 plan, this activity carries low trading significance.
