ACI Worldwide reported a strong second quarter for 2026, characterized by significant growth in adjusted earnings and a strategic expansion of its cloud-native payments platform. The company reported Q2 revenue of $430 million, representing a 7% increase compared to the previous year. This performance, driven by robust software segment results and successful platform deployments, has prompted the company to raise its full-year 2026 financial guidance for both revenue and adjusted EBITDA. For financial infrastructure leaders, these results signal a sustained demand for payments modernization and cloud-native solutions within the global banking ecosystem.
ACI Worldwide Q2 2026 Financial Performance
The second quarter of 2026 saw ACI Worldwide deliver substantial growth across several key financial metrics. Total revenue reached $430 million, up 7% year-over-year, while recurring revenue grew 5% to $336 million. The company's profitability saw a significant boost, with GAAP net income rising to $32 million from $12 million in the same period last year. Adjusted diluted earnings per share (EPS) surged by 54%, reaching $0.54.
The Payment Software segment was a primary driver of this growth, generating $196 million in revenue, a 9% increase. Notably, Issuing and Acquiring revenue within this segment grew 33% on a constant currency basis, fueled by large expansions from renewing customers. While Real-Time Payments revenue saw a decline to $23 million due to renewal timing, the overall segment adjusted EBITDA rose 12% to $94 million, benefiting from operating leverage and disciplined expense management.
In contrast, the Biller segment reported revenue of $234 million, a 5% increase. However, Biller revenue net of interchange fees fell 3% to $68 million, influenced by a high comparison from the prior year and specific discrete operating expenses. Despite these fluctuations, ACI Worldwide has maintained its full-year 2026 Biller revenue growth expectation in the high single digits.
Strategic Deployment of ACI Connetic
A critical component of ACI Worldwide's recent success is the successful deployment and adoption of its ACI Connetic platform. The company announced that it has successfully enabled ACI Connetic across eight major U.S. payment networks. This technical milestone is complemented by the acquisition of two new U.S.-based customers for the platform, which the company views as a validation of its cloud-native payments technology.
According to Thomas Warsop, President and CEO of ACI Worldwide, signing these two U.S. customers represents a significant milestone. He noted that these wins validate the strength of the cloud-native payments platform and reflect the growing demand for payments modernization within the world's largest banking market. This momentum in the U.S. market is a key factor in the company's decision to increase its full-year 2026 guidance.
The company's capital allocation strategy remains active, with $107 million spent on repurchasing 2.5 million shares year-to-date. ACI Worldwide maintains a healthy liquidity position with $167 million in cash on hand and total liquidity of $540 million under its credit facility. The company intends to continue allocating 50-60% of operating cash flow to share repurchases throughout the year, subject to market conditions.

FinanceInsyte's Take
In our view, ACI Worldwide’s Q2 2026 results demonstrate a successful pivot toward high-margin, cloud-native infrastructure. The 54% surge in adjusted diluted EPS, coupled with the expansion of the ACI Connetic platform into eight major U.S. networks, suggests that the company is successfully capturing the market's shift toward payments modernization. While the decline in Biller revenue net of interchange fees and the timing-related dip in Real-Time Payments revenue warrant observation, the strength in Issuing and Acquiring revenue indicates deep integration within existing client ecosystems. This signals that ACI is moving beyond simple service provision toward becoming a foundational layer for large-scale banking networks. The decision to raise full-year guidance despite fluctuations in net new ARR bookings suggests management has high confidence in the conversion of their existing pipeline and the high-margin nature of upcoming software license renewals.
