U.S. Securities and Exchange Commission

You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

Effective February 23, 2026, Charles Peters and Janet Estep resigned from the Board of Directors (the “Board”) of ACI Worldwide, Inc. (the “Company”). Mr. Peters’ and Ms. Estep’s decisions to resign were not due to any disagreement with the Company on any matter relating to its operations, policies, or practices.

In accordance with these guidelines, the Board has determined that Ms. deBeers is independent.

Item 1.01. Entry into a Material Definitive Agreement. On February 26, 2024, ACI Worldwide, Inc. (the “Company”) entered into a Refinance Amendment (the “Amendment”) to the Second Amended and Restated Credit Agreement, dated as of April 5, 2019 (as amended, restated, supplemented or otherwise modified from time to time, including by the Amendment, the “Credit Agreement”) among the Company, the subsidiary borrowers from time to time party thereto, the lenders from time to time party thereto, Bank of America, N.A., as administrative agent and a lender, BofA Securities, Inc., PNC Capital Markets LLC, Wells Fargo Securities, LLC, and TD Securities (USA) LLC, as Joint Lead Arrangers and Joint Bookrunners, and the other financial institutions party thereto.

The Amendment (i) provides a senior secured term loan facility (the “Term Loan Facility”) in an aggregate principal amount of $500 million, (ii) provides a senior secured revolving credit facility (the “Revolving Loan Facility” and together with the Term Loan Facility, the “Credit Facilities”) of up to $600 million, and (iii) extends the maturity date of the Facilities to February 26, 2029 (the “Maturity Date”), provided that if any of the Company’s 5.750% Senior Notes due 2026 are outstanding on the date that is 91 days before the maturity thereof (the “Springing Maturity Date”), and the Company does not have sufficient liquidity as of such date, the Maturity Date will be the Springing Maturity Date. The Revolving Loan Facility includes a $35 million sublimit for the issuance of standby letters of credit and a $20 million sublimit for swingline loans. Amounts repaid under the Revolving Facility may be reborrowed.

Borrowings under the Credit Facilities bear interest at a rate equal to, at borrower’s option, either (A) a base rate determined by reference to the highest of (1) the rate of interest per annum publicly announced by Bank of America as its prime rate, (2) the federal funds effective rate plus 0.5%, (3) term SOFR plus 1%, and (4) 1% or (B) term SOFR for applicable interest period relevant to such borrowing, in each case plus an applicable margin. The applicable margin for borrowings under the Credit Facilities is, based on the calculation of the applicable consolidated total leverage ratio, between 0.5% to 1.5% with respect to base rate borrowings and between 1.5% and 2.5% with respect to term SOFR rate borrowings. The Company is also required to pay customary fees under the Credit Facility.

The Company’s subsidiaries, ACI Worldwide Corp. and ACI Payments, Inc. are co-borrowers under the Credit Agreement. The obligations of the borrowers under the Credit Facilities and the obligations of the Company and its subsidiaries under certain hedging arrangements and cash management arrangements entered into with lenders under the Credit Facilities (or affiliates thereof) are jointly and severally guaranteed by the Company
