Fiserv’s shares plunged 10.7% post-earnings as investors were disappointed by soft revenue growth impacted by lower inflation and interest rates in Argentina, margin pressures from ongoing investments, and a cautious outlook on near-term financial results despite operational progress.

• Clover merchant revenue growth was constrained by adverse macro factors in Argentina, offsetting solid Clover GPV volume gains.
• Merchant Solutions saw 27 new bank partnerships but flagged potential headwinds from higher gas prices affecting consumer spending patterns.
• Financial Solutions experienced solid volume growth in Finxact and payments (excluding BillPay) but continued to face elevated core bank account and revenue attrition above long-term trends.
• Incremental expenses related to client service improvements and strategic investments weighed on margins and masked early operational gains.
• Management emphasized the transition nature of 2026, with meaningful financial improvements expected only in the second half of 2026 and into 2027.
