Activist Investor Jana Partners’ Take On Lyons

Activist investor Jana Partners recently cheered the effort to appoint Lyons as the company's leader in 2025, who has since helped rebuild the company’s credibility, according to Reuters.

Jana Partners has also been pushing the company to unload non-core assets and pursue board refreshment. It owns about a 1% stake in Fiserv.

The firm’s managing partner, Scott Ostfeld, who recently spoke at Wolfe Research's annual Activist Conference, said: “Fiserv is in the early innings of rehabilitating its credibility with customers ​and investors. We believe further portfolio reshaping and expanding the board's refreshment process to add relevant experience ​would speed the credibility rebuilding process and lead to a re-rating of the stock."

In a recent note, Morningstar analyst Brett Horn said that 2026 will be a reset year for Fiserv, with the company likely to see only marginal top-line growth and some margin compression.
