ACI Worldwide's Kinetic Pivot Gains Traction: First U.S. Customers, AI Integration, and a Guidance Raise
ACI Worldwide delivered a strong second quarter, but the real story is the strategic transition from legacy software to a modern, cloud-native payments platform (ACI Kinetic). The company reported 7% revenue growth, 12% adjusted EBITDA growth, and 54% EPS growth, and raised full-year guidance once again. More importantly, management signed the first U.S.-based Kinetic customers and showcased AI capabilities embedded across its portfolio—signals that the long-awaited modernization is beginning to pay off.
Financial Momentum and Raised Guidance
Revenue reached $430 million for the June quarter, up from $401 million a year earlier, while adjusted EBITDA expanded 12% to $91 million, pushing margin from 32% to 34%. CFO Robert Leibrock highlighted the discipline behind the raise: “Based on first-half performance and the strength of our pipeline, we are increasing our full-year FY ’26 outlook.” — Robert Leibrock, Chief Financial Officer · 2026-08-06 This is the second consecutive quarter of upward revision, reflecting confidence in the second half despite a 40/60 weighting toward Q4 that stemmed from the timing of high-margin license renewals. Operating cash flow ran at $135 million year-to-date, supporting a balanced capital-allocation strategy that included $107 million in repurchases. Total Revenue confirms the sustained growth trajectory.
Kinetic: From Vision to First Customers
The quarter's headline event was the first U.S.-based Kinetic sale, followed by another shortly after quarter-end. Thomas Warsop framed it as validation of the platform's appeal: “We signed our first U.S.-based ACI Speedpay Kinetic customer in the quarter, and we have already signed another in Q3.” — Thomas W. Warsop, President and Chief Executive Officer · 2026-08-06 The pipeline is growing faster than any other solution set, and while Kinetic revenue is not yet a meaningful contributor, it is reshaping how customers view ACI. As Warsop noted in Q&A, “The one we signed in the quarter, it is an existing customer, and that’s great news actually, because we’re attacking opportunities across all types of customers.” — Thomas W. Warsop, President and Chief Executive Officer · 2026-08-06 This underscores that Kinetic is not just a net-new hunting tool but also an expansion lever for the installed base—echoing the company's focus on existing customers as a key growth driver. In fact, net new New ARR bookings remain healthy, with Biller strength offsetting a slower Payment Software quarter due to timing.
AI Isn't Just a Roadmap—It's Driving Productivity
Management sprinkled the call with concrete AI outcomes, not just aspirations. Warsop described an internal tool that compresses payment-scheme interpretation from weeks to hours: “our AI mandate analyzer is reducing the time required to interpret payment scheme mandates from two to three weeks to minutes or hours.” — Thomas W. Warsop, President and Chief Executive Officer · 2026-08-06 He also cited a 50% reduction in engineering effort on a common product, 6,000+ hours saved, and an automated retrofit agent team that will handle up to 85% of manual support workflows. These AI capabilities are being embedded directly into Kinetic and Speedpay One, and they also feed into an payment type-agnostic platform that can orchestrate across cards, real-time rails, and emerging digital assets. The company is not just talking about AI—it is using it to improve margins and accelerate customer implementation.
In terms of test automation, our AI mandate analyzer is reducing the time required to interpret payment scheme mandates from two to three weeks to minutes or hours.
Segments: Payment Software Leads, Biller Stays on Track
Payment Software revenue grew 9%, with Issuing and Acquiring surging 37% on renewals and expansions. This segment's adjusted EBITDA margin held at 48%—the leverage of recurring software. Meanwhile, Biller revenue rose 5%, but CFO noted tough comparisons and a one-time partnership termination charge that were within adjusted EBITDA. Management reaffirmed second-half Biller acceleration to upper single-digit growth as new logos and Speedpay One implementations kick in. The balance sheet remains healthy with net leverage at 1.2x, giving flexibility for M&A.
Why This Matters
The real change is perceptual: ACI is shedding its image as a legacy vendor. Warsop explained that early Kinetic conversations now pivot to “how can we help you change the way you do business?” This elevates the dialogue from selling software to co-designing a customer's future. The company had previously invested heavily in the platform—“we have increased our investment in Kinetic, and that's absolutely true” — Thomas Warsop, CEO · 2026-05-07 (from the May call)—and now that bet is yielding visible momentum. As Warsop noted in Q&A: “We are having very different dialogues with customers and prospects now as we lead with Kinetic.” — Thomas W. Warsop, President and Chief Executive Officer · 2026-08-06 With the stock up ~18% over the past three months but still ~13% below its July peak, the market is waiting for evidence that Kinetic becomes a revenue accelerant—not just a pipeline driver. Given the strong execution, the raised guide, and the first U.S. wins, ACI appears closer to turning that promise into a durable growth story.
