• Aggregate Market Value: $102,421.32 (~$85.78 per share).

Historical Context & Market Impact

Over the preceding three months, Ms. Schulz executed consistent monthly sales of identical share quantities:

• July 2, 2026: 1,194 shares for $76,893.60
• August 4, 2026: 1,194 shares for $71,735.52
• September 2, 2026: 1,194 shares for $104,916.78

Given the total outstanding share base of 234,685,190 shares, this proposed transaction represents an infinitesimal fraction (<0.001%) of total common stock. Combined with the pre-arranged Rule 10b5-1 trading schedule and programmatic post-vesting pattern, this transaction carries low trading significance.
