Rhea-AI Filing Summary

River Road Asset Management, LLC filed a Schedule 13D reporting a significant stake in UniFirst Corp. (UNF). River Road, a Delaware-organized investment adviser, reports beneficial ownership of 881,303 shares of UniFirst common stock, representing 6.1% of the 14,565,659 shares outstanding as of October 22, 2025. The firm used approximately $134,947,269.25 of client funds under its management to acquire this position.

Insights

Equity Ownership & Governance Analyst

River Road reports a 6.1% UniFirst stake, signaling active but non‑control-oriented engagement potential.

River Road Asset Management has disclosed beneficial ownership of 881,303 UniFirst shares, equal to 6.1% of the 14,565,659 shares outstanding as of October 22, 2025. The position, purchased with about $134,947,269.25 of client funds, makes River Road a notable institutional holder with sole voting power over 763,959 shares and sole dispositive power over all 881,303 shares.

The filing states the stake is held for investment in the ordinary course, and that River Road does not intend to seek control or manage UniFirst’s day-to-day operations. At the same time, it explicitly contemplates discussions about operations, strategy, governance, capital allocation, and potential board nominees, and notes that such analysis and discussions may result in material changes to its ownership. This language leaves room for active engagement without a formal control agenda.

The transaction history shows numerous open-market buys and some sales between September 15, 2025 and November 14, 2025 at prices largely in the $150–$170 range, indicating gradual accumulation rather than a single block purchase. Future UniFirst disclosures or additional amendments by River Road could clarify whether its role remains purely investment-focused or evolves toward more assertive shareholder engagement.
