On today's call, we will discuss ACI Worldwide's Q1 2026 results, as well as our updated financial outlook for the remainder of the year. You can find the full text of these statements in our earnings press release and in our filings with the SEC. Bobby will then review our financial results in more detail, including segment performance, cash flow, and updated outlook for 2026. As always, I appreciate you joining us for our Q1 2026 earnings call.

We're in a strong competitive position, we're increasingly optimistic about the outlook for our business. If I look at the Q1, we delivered 6% organic revenue growth in constant currency, that growth compares against the strongest Q1 in the company's history last year. That is the strongest quarter until this quarter since we grew on top of that. Our focus on operational efficiency, combined with the operating leverage in our model, drove over 160 basis points of FX adjusted, net adjusted EBITDA margin expansion and 8% adjusted EBITDA growth.

The combination of this overall strong operating performance and our continued share repurchases, I'll detail that a little bit later, translated to double-digit growth in adjusted EPS. As we regularly discuss, our strategy emphasizes growth within our core vertical markets, disciplined operational execution, and a return-driven approach to capital allocation. Our growth strategy is built on expanding within our existing customer base in addition to winning new logos and of course, accelerating innovation all along the way. Within our Payment Software segment, we took a major step forward in 2025 when we unified our bank and merchant businesses into what we now call Payment Software.

What went well
  • Total revenue of $426 million, up 8% year-over-year as reported and 6% in constant currency, delivered on top of the strongest Q1 in company history last year (which grew ~25%).
  • Adjusted EBITDA of $105 million, up 12% year-over-year (8% in constant currency), with adjusted EBITDA margin expanding to 38% from 36% and over 160 basis points of FX-adjusted margin expansion.
  • Double-digit growth in adjusted EPS, driven by operating leverage plus continued share repurchases (1.5 million shares for ~$65 million in the quarter).
  • Total new ARR bookings grew 39% to $12 million, with strength across both Payment Software and Biller (majority attributable to Biller/Speedpay).
  • Real-time payments revenue grew over 20% (22% in constant currency) and merchant grew 21%, driven by transaction-based volume growth within the existing customer base.
  • Biller segment revenue grew 10% to $212 million with EBITDA margin net of interchange up more than 200 basis points to 51%, on new logos and expansions across utilities, insurance, government, and consumer finance.
What went wrong
  • Operating cash flow declined to $64 million from $78 million a year ago, due to timing and working capital including a higher concentration of billings late in March (expected to normalize in Q2).
  • New license and services bookings of $50 million were flat against a strong prior-year comparison.
  • Payment Software grew only 2% in constant currency as fraud management and issuing/acquiring were essentially flat, lapping an exceptionally strong prior-year quarter.
