FactSet's board appointed Sanoke Viswanathan, a 15-year JPMorgan Chase veteran who is currently CEO of its International Consumer and Wealth business, as chief executive effective September 1, 2025 or another mutually agreed date. He will also join the board on that date, succeeding F. Philip Snow, who is retiring as CEO and director. The filing sets out a compensation package for Viswanathan that includes a $22,000,000 performance option award and a $13,000,000 make-whole cash payment, which shareholders will weigh alongside the leadership transition.
Viswanathan, age 50, has been CEO of JPMorgan's International Consumer and Wealth since June 2024; Snow notified the company of his retirement on May 28, 2025.
Snow stays on as a special advisor to the board and Viswanathan through November 15, 2025, or a later mutually agreed date, and his departure is not tied to any disagreement with the company.
Viswanathan's pay includes a $1,000,000 base salary, a 200% target cash bonus, and a $22,000,000 performance-vesting stock option award for fiscal 2026 and 2027 granted in fall 2025.
Briefs are written by AI from the filing text and can contain mistakes — open the filing before acting on anything. Impact (1-5) and tone are the AI's reading of the filing for shareholders, not a price forecast. Not investment advice.
Briefs marked “Written later” were written in November 2026 for filings that were by then more than three weeks old, so months before mid-October 2026 hold a selection: every material 8-K of the past year for the 100 largest companies we cover and the last 15 important 8-Ks of every other one. Briefs the number check holds back are not shown or counted. Also: the last 45 days, briefs by company, A–Z and the live SEC filings wire.
