Morningstar (MORN) concentration risks

Morningstar's disclosed concentration sits within its Retirement business line. MRA represented more than half of Morningstar Retirement AUMA and accounted for the majority of revenue in 2025, a medium-sized structural exposure, while fiduciary services was the second-largest Retirement product by revenue, accounting for approximately a quarter of overall AUMA, also medium-sized. Together these two products account for the substantial majority of the Retirement segment's assets under management and administration. Both exposures are structural rather than dependency-based — they describe how Morningstar's Retirement revenue is mixed across product lines rather than reliance on any single client or counterparty. This means the segment's performance is sensitive to broader shifts in demand for managed retirement account services and fiduciary advisory services specifically, rather than to the loss of a single customer relationship. Because MRA and fiduciary services together make up the clear majority of the Retirement product mix, a slowdown or competitive pressure affecting either product category — particularly MRA, given its larger share — would disproportionately affect segment results relative to a more evenly distributed product lineup. No customer, geographic, or supplier concentration is disclosed alongside these product-mix figures, so this Retirement product concentration is the primary signal available from the filing.
