ACI Worldwide closed the first half of 2026 with a clean and somewhat rare piece of evidence: two paying U.S. customers signed for ACI Connetic, the cloud-native payments hub the company has been investing behind for several years, and Connetic went live across eight major U.S. payment networks. The quarter itself was a steady execution print, not a breakout. Revenue of $430.4 million was up 7% on a reported basis and 6% in constant currency, and net adjusted EBITDA margin expanded to 34% from 32% in the year-ago period, which is the kind of incremental margin lift the equity is supposed to deliver on the way to becoming a cloud-led franchise. Adjusted diluted EPS of $0.54 was up 54% on a much lower tax rate and lighter interest expense, and the company raised full-year guidance for both revenue and adjusted EBITDA. The market is now valuing the equity at roughly $5.4 billion, against a TTM adjusted EBITDA of approximately $380 million, which is a 14x multiple that looks reasonable for a 7%-growing software franchise but does not yet pay for a Connetic-driven re-rating. The load-bearing question for the next six months is whether the two-customer Connetic milestone becomes a four-to-six-customer base by year-end, because the bear case rests on Connetic being a slower-than-expected commercial ramp that prevents the multiple from compounding. The falsification test is the Q3 2026 print on November 5 plus the full-year 2026 license and services bookings number, which management has guided to growth against the 2025 base of $330 million.
