ACI Worldwide (ACIW) Stock Forecast & Price Target

ACI Worldwide is viewed positively because its core Payment Software franchise is delivering solid growth, with 2Q revenue up 7% Y/Y to $430M and Payments Software up 10% Y/Y, supported by an expanding Bank sub-segment and strong recurring revenue that made up 78% of sales. Margin quality is also improving, as higher-margin Software License Fees rose 21% Y/Y to $69M and adjusted EBITDA increased 12% Y/Y to $91M, lifting related margins by 200bp to 34.3% of total revenue. The outlook is further reinforced by raised 2026 guidance, a 2025 mix shift toward recurring revenue, natural FX hedges, and long-term demand drivers from real-time payments, front-loaded renewals, and continued debt reduction and share repurchases.

ACI Worldwide is facing a negative fundamental setup because new ARR bookings fell 25% Y/Y to $18M in 2Q and 15% over the trailing twelve months, while License and Services bookings also weakened over the same periods, signaling softer demand momentum. Revenue quality is also under pressure: Biller grew 6% Y/Y to $234M, but net revenue fell 3% Y/Y to $69M after $166M of pass-through interchange costs, and 3Q guidance implies a 12%-14% revenue decline plus a 44%-47% drop in adjusted EBITDA to $90M-$95M. The business remains exposed to sharp quarterly volatility from ASC 606 revenue recognition, lumpy renewals, and seasonal reliance on 4Q, while economic sensitivity, regulatory changes, and industry consolidation could further delay upgrades and weigh on execution.
