ACI Worldwide (ACIW) Stock Forecast & Price Target

ACI Worldwide is well positioned because 2Q results were within 1% of revenue and adjusted EBITDA forecasts, while adjusted EBITDA still rose 12% year over year to $91M and margins expanded 200 basis points to 34.3% on a higher mix of high-margin Software License Fees. Its 2026 guidance now implies 8%-9% revenue growth to $1.90B-$1.93B and 8%-11% adjusted EBITDA growth to $545M-$560M, supported by recurring revenue, a cloud-native Payments Hub expansion into mid-tier banks, and strong exposure to real-time payments demand. The investment case is further reinforced by modest debt at a 1.2 times net debt-to-trailing EBITDA ratio, continued share repurchases, and potential value creation if the Biller segment is divested at a compelling multiple.

ACI Worldwide is facing weakening core demand as 2Q new ARR bookings fell 25% Y/Y to $18M, trailing-twelve-month new ARR bookings dropped 15% Y/Y to $68M, and License and Services bookings also declined 12% Y/Y to $255M, signaling pressure in future growth. Despite Biller segment revenue rising 6% Y/Y to $234M, $166M of pass-through interchange costs masked underlying weakness, as net revenue fell 3% Y/Y, and management’s 3Q guide implies a 12%-14% revenue decline and a 44%-47% drop in adjusted EBITDA to $90M-$95M. The bearish outlook is further supported by ACI’s history of volatile, back-end-loaded results driven by upfront ASC 606 revenue recognition, high-margin software license timing, and exposure to economic and regulatory delays that can disrupt upgrade cycles and margin recovery.
