ACI Worldwide Inc. raised its 2026 revenue outlook to between $1.89 billion and $1.92 billion on Thursday [1].

The update signals strong momentum for the San Jose-based payments technology firm as it navigates a shifting global financial landscape. By increasing its guidance, the company indicates confidence in its ability to scale operations and capture more market share in the digital payments sector.

During a Q1 2026 earnings call, the company also raised its adjusted EBITDA outlook to a range of $540 million to $555 million [1]. Management said the positive shift was due to a strong start to the year, which included six percent organic revenue growth in constant currency [1].

Executives said that margin expansion and a rise in bookings contributed to the revised figures. These metrics suggest that the company is seeing increased demand for its payment software and services across its global client base.

"We're pleased with the start to 2026 and increasingly optimistic about the outlook for our business," CEO, President and Director Thomas Warsop said [2].

The company delivered the announcement via a press release and the earnings call, detailing the financial trajectory for the remainder of the year. The revised forecasts reflect the company's current internal projections based on the performance observed in the first quarter [3].
