A leadership shake-up at the fintech Fiserv sent shares into a tailspin. But while the chief executive's exit rattled public investors, it triggered an entirely different reaction from insiders.

On June 15, Fiserv announced that CEO Mike Lyons was stepping down to take the top role at Truist Securities. Lyons had spearheaded the company's turnaround since joining Fiserv in January 2025.

Shares dropped 11% on the announcement. In the day that followed, Fiserv's chief financial officer, chief legal officer, and three more insiders bought shares.

Leading the purchases were legal officer Adam Rosman and CFO Paul Todd. They both made their moves on June 16.

Rosman bought 10,150 shares for $49.33 each, totaling $500,699 worth of stock. His last Fiserv stock buy was in December 2025.

Todd snapped up 10,060 shares for an average price of $49.70 each, totaling $499,982. It was his first open-market purchase of company stock since the end of last year.

Also on June 16, three board members bought a combined 11,611 shares for $572,973. The bulk was bought by Chairman Gordon Nixon, the former CEO of Royal Bank of Canada, who picked up 7,500 shares for $49.57 each, or $371,775.

Fiserv stock has fallen 28% this year. Shares plunged 67% last year, making it the second-worst performer in the S&P 500 behind The Trade Desk.

The last wave of insider buying occurred in December, weeks after the stock suffered a historic one-day drop. Fiserv told Barron's at the time that its executives "maintain meaningful share positions" in the company.
