Context

This was a compensation-related equity award (annual retainer) rather than an open-market buy or sale. Such awards are routine for directors and reflect compensation for service; they are not direct evidence of an insider’s decision to buy or sell shares on the market. For exact post-transaction beneficial ownership and any vesting or restriction details, consult the full amended Form 4 (accession 0001193125-26-335219).
