Why Fiserv Stock Triumphed on Tuesday

Fiserv stock surged nearly 13% on Tuesday following an encouraging Q3 2026 earnings report. Despite revenue declining 1% year-over-year to $4.85 billion and adjusted net income falling 15% to $936 million, the company beat analyst expectations on earnings per share ($1.75 vs. $1.72 expected). Key positives included improved banking customer retention, major client wins, a doubled cost-saving target to $1 billion, and resumption of a $500 million share buyback program.
