“Signing two U.S.-based customers for ACI Connetic is a significant milestone and validates both the strength of our cloud-native payments platform and the growing demand for payments modernization in the world’s largest banking market,” said Thomas Warsop, President and CEO of ACI Worldwide.

“In the second quarter, we delivered 7% revenue growth, expanded EBITDA margins and continued to execute our balanced capital allocation strategy. We continued to invest in ACI Connetic to support long-term organic growth and, at the same time, returned capital to shareholders through share repurchases. As a result of our strong first-half performance, we are increasing our full-year revenue and adjusted EBITDA guidance. We enter the second half of 2026 with strong momentum, a healthy pipeline and confidence in our ability to create long-term shareholder value.”

Net income of $32 million in Q2 2026 compares to net income of $12 million in Q2 2025. Total adjusted EBITDA in Q2 2026 was $91 million, up 12% from Q2 2025, or up 9% on a constant currency basis. Net adjusted EBITDA margin in Q2 2026 was 34%, up from 32% in Q2 2025.

GAAP diluted EPS in Q2 2026 was $0.31 and adjusted diluted EPS was $0.54, up 54% from Q2 2025.

PAYMENT SOFTWARE SEGMENT RESULTS

Payment Software revenue in Q2 2026 was $196 million, up 9% from Q2 2025, or up 7% on a constant currency basis. The segment saw particular strength from Issuing and Acquiring revenue, which increased 33% on a constant currency basis versus Q2 2025, driven by large expansions with renewing customers. Payments Intelligence and Merchant Payments revenue each increased 3% on a constant currency basis in the quarter. Real-Time Payments revenue was $23 million, down from last year due to renewal timing. Recurring revenue in the segment, which represents SaaS and Maintenance revenues, increased 3%, versus Q2 2025, or 2% on a constant currency basis.

Payment Software adjusted EBITDA in Q2 2026 was $94 million, up 12%, or up 9% on a constant currency basis from Q2 2025 driven by operating leverage and disciplined expense management, partially offset by ongoing growth investments. As a result, net adjusted EBITDA margin in Q2 2026 was 48%, up from 46% in Q2 2025.

BILLER SEGMENT RESULTS

Biller revenue in Q2 2026 was $234 million, up 5% from Q2 2025 on a reported and constant currency basis. Biller revenue, net of interchange fees, was $68 million, down 3%, from Q2 2025, driven by a strong comparison with significant new onboarding and transactions in the same period last year, as previously discussed. Based on new business wins and current transactions trends, the company’s expectation for full-year 2026 Biller revenue growth in the high single digits remains unchanged.

Biller adjusted EBITDA in Q2 2026 was $35 million, down 13%, from Q2 2025. Net adjusted EBITDA margin, net of interchange fees, was 51%, down from 56% in Q2 2025. Results in the current period reflected lower net revenue compared to the strong prior-year, the impact of certain discrete operating expenses and continued investments in Speedpay ONE.

YEAR-TO-DATE 2026 FINANCIAL SUMMARY

Year-to-date 2026 total revenue was $856 million, up 8% from year-to-date 2025, or up 6% on a constant currency basis. Recurring revenue was $649 million, up 7% from year-to-date 2025, or up 6% on a constant currency basis. Year-to-date 2026 net income of $70 million compares to net income of $71 million for year-to-date 2025, which included a $22 million after-tax gain on the sale of our minority interest in Mindgate. GAAP diluted EPS for year-to-date 2026 was $0.69 and adjusted diluted EPS was $1.16, up 35% from year-to-date 2025.

Total adjusted EBITDA for year-to-date 2026 was $196 million, up 12% from year-to-date 2025, or up 8% on a constant currency basis. Net adjusted EBITDA margin for year-to-date 2026 was 36%, up from 34% in year-to-date 2025.

NEW BOOKINGS

Net new ARR bookings in Q2 2026 were $18 million, down 25%, from Q2 2025, as strength in Biller segment ARR growth was offset by the timing of expected Payment Software contracts. New license and services bookings were $59 million in Q2 2026, up 2% from Q2 2025. Net new ARR bookings for the trailing twelve months ended June 30, 2026 were $68 million, down 15% from 2025. New license and services bookings for the trailing twelve months ended June 30, 2026 were $255 million down 12% from 2025. The company expects full year 2026 growth for both new ARR and new license and services bookings.

BALANCE SHEET AND LIQUIDITY, CASH FLOW, AND REPURCHASES

ACI ended Q2 2026 with $167 million in cash on hand and a debt balance of $826 million, representing a net debt leverage ratio of 1.2x adjusted EBITDA. ACI had total cash and available liquidity under its credit facility of $540 million. Operating cash flows for year-to-date 2026 were $135 million, up from $128 million for year-to-date 2025.

During Q2 2026, the company repurchased approximately 948,000 shares for approximately $41 million at an average price of $43.75. Year-to-date 2026, repurchases totaled 2.5 million shares for approximately $107 million at an average price of $42.75. The company has approximately $349 million remaining available on the share repurchase authorization and continues to expect to allocate 50-60% of operating cash flow to share repurchases for the full year, subject to market conditions.

RAISING 2026 GUIDANCE

Based on first half 2026 performance and the strength of its pipeline, the company is increasing its full-year 2026 guidance. The company now expects revenue in the range of $1.895 billion to $1.925 billion, up from the prior range of $1.890 billion to $1.920 billion, and adjusted EBITDA in the range of $545 million to $560 million, up from $540 million to $555 million. For the second half of 2026, the company continues to expect an approximately 40% and 60% revenue weighting for Q3 and Q4, respectively, driven by the timing of high margin Payment Software license renewals. This equates to revenue of $417 million to $427 million in Q3 2026. Adjusted EBITDA in Q3 2026 is expected to be $90 million to $95 million.
