"Payments modernization continues to accelerate, and ACI is at the center of it," said Thomas Warsop, President and CEO of ACI Worldwide. "In the quarter, Real Time Payments and Merchant each grew more than 20%, Biller delivered 10% growth on top of last year's double‑digit performance, and new ARR bookings grew 39% across the company. At the same time, our ACI Connetic pipeline continues to expand, underscoring strong market demand for our cloud‑native payments platform. The decision last year to operate our Payment Software and Biller businesses as two distinct segments has sharpened our focus, accelerated organic growth, and consistently enabled us to outperform expectations. We are committed to our capital allocation framework, investing in organic growth, pursuing strategic M&A, and returning capital to shareholders."

"We entered 2026 with momentum, executed ahead of expectations in the first quarter, and are raising our full‑year outlook," Warsop concluded.
