Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Ownership Cap Shifts to Aggregate 40%
If you own IEX Group stock, the Charter now measures the 40% ownership cap across all shares combined instead of by each class of stock. That means you could own more than 40% of one class (common or preferred) so long as you do not own more than 40% of the Corporation's total outstanding shares. This change became operative upon filing on December 19, 2025.
Exchange Members' 20% Limit Made Aggregate
IEX Exchange Members who hold IEXG stock are now subject to the 20% ownership restriction measured across all outstanding shares of the Corporation, rather than 20% of any single class of stock. This amendment also became operative upon filing on December 19, 2025.
Automatic Pro Rata Vote Redistribution
The Charter adds a rule that if one or more shareholders would exceed the 20% voting power limit, any votes above that 20% limit will be automatically and proportionally redistributed among the remaining voting stockholders. If redistribution would cause another shareholder to exceed 20%, the adjustment repeats until no shareholder exceeds the limit. This provision is operative as of December 19, 2025.
