This Form 4/A corrects a clerical error in the original June 17 filing, revealing that Chief Regulatory & Communications Officer Christopher Guttman-McCabe sold 31,415 more shares than initially reported. The total sale value rises from approximately $7.5 million to $10.04 million, a 33% increase. The sale occurred on June 15 at prices between $78.73 and $84.40, well below today's $91.53. The amendment does not change the nature of the transaction—an open-market sale by a non-CEO officer—but the larger size makes it more significant for investors tracking insider distribution.
