ACI Worldwide CFO Leibrock Sells 1,289 Shares at $42.80

ACI Worldwide, Inc. CFO Robert William Leibrock filed a Form 4 disclosing the sale of 1,289 shares of common stock on June 6, 2026, at a price of $42.80 per share. The transaction was coded as a disposition (D) and reduced Leibrock's holdings to 208,260 shares. According to the filing footnote, the shares were surrendered to pay tax liabilities associated with the vesting of 4,113 restricted stock units, representing one-twelfth of RSUs granted on March 6, 2026. This appears to be a routine tax withholding transaction related to equity compensation vesting rather than a discretionary sale. Leibrock remains a significant shareholder with over 200,000 shares following the transaction. The filing was signed on June 8, 2026, and reports the officer's continued direct ownership of ACIW stock.
