Explanatory Note

This current report on Form 8-K/A (the “Amendment”) amends and supplements the current report on Form 8-K filed by Paymentus Holdings, Inc. (the “Company”) with the U.S. Securities and Exchange Commission (the “SEC”) on June 8, 2026 (the “Original Form 8-K”). The Original Form 8-K reported the final voting results of the Company’s 2026 Annual Meeting of Stockholders held on June 5, 2026 (the “2026 Annual Meeting”). The sole purpose of this Amendment is to disclose the Company’s decision regarding how frequently it will conduct future stockholder advisory votes to approve the compensation of the Company’s named executive officers pursuant to the compensation disclosure rules of the SEC (“say-on-pay votes”). No other changes have been made to the Original Form 8-K.

Item 5.07 Submission of Matters to a Vote of Security Holders.

As previously reported in the Original Form 8-K, in a non-binding advisory vote by the Company’s stockholders on the frequency of future say-on-pay votes held at the 2026 Annual Meeting, every “one year” received 659,717,563 votes, every “two years” received 5,003 votes and every “three years” received 844,276 votes, with 16,815 abstentions and 8,121,639 broker non-votes. The Company’s Board of Directors (the “Board”) has considered the outcome of this advisory vote and has determined, consistent with the recommendation by the Board in the proxy statement for the 2026 Annual Meeting, that the Company will hold future say-on-pay votes on an annual basis until the occurrence of the next advisory vote on the frequency of say-on-pay votes. The next advisory vote regarding the frequency of say-on-pay votes is required to occur no later than the Company’s 2032 Annual Meeting of Stockholders.
