ACI Worldwide Signals Confident Growth in Earnings Call

ACI Worldwide, Inc. ((ACIW)) has held its Q1 earnings call. Read on for the main highlights of the call.

ACI Worldwide’s latest earnings call struck an upbeat tone, with management emphasizing broad-based growth in revenue, recurring streams and ARR, alongside expanding margins and a strengthened balance sheet. Investors also heard about active buybacks and rising demand for the firm’s software-led payments solutions, even as executives acknowledged cash-flow timing issues, slower license growth and a gradual adoption path for its Kinetic platform.

Revenue Growth and Recurring Mix

ACI Worldwide reported first-quarter revenue of $426 million, an 8% increase year over year, or 6% in constant currency, underscoring solid top-line momentum. Recurring revenue climbed 10% to $313 million, growing faster than the headline figure and reflecting strong demand for software-driven, subscription-like payment solutions.

Margin Expansion and Profitability

Adjusted EBITDA rose 12% to $105 million, or 8% in constant currency, signaling operating leverage as the business scales. The adjusted EBITDA margin improved to 38% from 36% a year earlier, adding roughly 200 basis points and reinforcing the narrative that efficiency initiatives are converting revenue gains into higher profitability.

ARR Momentum and Biller-Led Growth

Net new ARR bookings surged 39% to $12 million, with management highlighting the Biller business as the main contributor to this recurring revenue pipeline. The jump in ARR suggests a more durable revenue base over time, as customers increasingly opt for long-term, software-led arrangements rather than one-off licenses.

Payment Software Segment Trends

Payment Software revenue reached $214 million, with constant-currency growth of 2%, while SaaS revenue within this segment rose 11%, excluding FX, showing traction in cloud delivery models. Recurring revenue from SaaS and maintenance increased 9% reported, driven by standout performance in real-time payments, up 22%, and merchant solutions, up 21% in constant currency.

Biller (Speedpay One) Outperformance

The Biller segment delivered $212 million of revenue, rising 10% year over year as digital bill-pay volumes continued to scale. Revenue net of interchange grew 5%, and segment adjusted EBITDA increased 10% to $34 million, pushing EBITDA margin net of interchange above 51% and reflecting benefits from new implementations and higher transaction volumes.

Kinetic Platform as Strategic Engine

Management underscored the Kinetic platform as a central long-term differentiator, citing expanded capabilities in card modernization, U.S. multi-rail clearing and embedded fraud and verification. Early SaaS wins and a growing pipeline are helping drive renewals, expansions and new-logo interest, though initial go-lives will contribute only modest, ratable revenue this year and are not material to near-term guidance.

Capital Returns and Share Repurchases

ACI stepped up capital returns with the repurchase of 1.5 million shares in the quarter for roughly $65 million, bringing total buybacks since the start of 2025 to about 5.7 million shares, more than 5% of the share count. Management reiterated a commitment to return 50% to 60% of operating cash flow to shareholders via buybacks in 2026, supported by a remaining $391 million authorization.

Balance Sheet Flexibility and Leverage

The company ended the period with $162 million in cash and $812 million of total debt, translating to net leverage of 1.3 times adjusted EBITDA, comfortably below its 2-times target. Total liquidity of $560 million provides room to fund growth initiatives, pursue selective investments and continue shareholder returns without straining the balance sheet.

Cash Flow and Working-Capital Timing

Operating cash flow came in at $64 million, down from $78 million a year earlier, a weakness management attributed mainly to working-capital timing. A concentration of billings late in March delayed collections into the second quarter, and executives indicated that cash generation should normalize as these payments are received.

Flat License and Services Bookings

New license and services bookings totaled $50 million, essentially flat against a strong prior-year comparison, suggesting limited growth in upfront deals. This dynamic underscores the shift toward recurring ARR and may temper near-term revenue spikes, even as the company builds a more stable, recurring-oriented business model.

Areas of Limited Product Growth

Not all product lines participated in the growth story, with fraud management revenue described as essentially flat year over year. Management acknowledged that some offerings are still ramping and have yet to deliver meaningful growth, highlighting a mixed picture beneath the otherwise strong segment performance.

Kinetic Adoption Pace and Complexity

While Kinetic is strengthening the pipeline and helping secure renewals and expansions, management emphasized the complex, multi-year nature of migrating large customers. These lengthy sales and implementation cycles mean that substantial revenue contributions from major Kinetic projects will build gradually, limiting its impact on near-term figures despite strategic importance.

Macro Risks and Seasonal Patterns

Executives flagged macro and geopolitical risks, including tensions in the Middle East and potential energy shocks, as sources of uncertainty, even though payments demand remained resilient in the first quarter. They also noted that implementations and renewals are heavily skewed toward the fourth quarter, creating seasonality that could pressure mid-year performance if projects slip or scheduling shifts.

Raised Outlook and Forward Guidance

Management raised full-year 2026 guidance, now projecting revenue growth of 7% to 9% to between $1.89 billion and $1.92 billion, with both Payment Software and Biller expected to grow in the upper single digits. Adjusted EBITDA is now forecast at $540 million to $555 million, implying 7% to 10% growth, while second-quarter revenue is guided to $420 million to $440 million and adjusted EBITDA to $85 million to $95 million, with performance expected to skew toward a stronger fourth quarter.

ACI Worldwide’s earnings call painted a picture of a payments company steadily transitioning toward higher-quality, recurring revenue while expanding margins and rewarding shareholders. Investors will be watching how quickly Kinetic, Biller momentum and license-driven second-half activity convert into sustained growth, particularly against a backdrop of macro uncertainty and pronounced seasonal swings.
