Activist fund Mantle Ridge LP reduced its directly held DLTR position by 91.4%, selling 2.23M shares at $111.31 for $248.3M — pricing the exit 6.8% below the 90-day high and 29.6% above the 90-day low, suggesting deliberate but not distressed liquidation. Mantle Ridge built its only prior DLTR position in December 2023 at $99.3M, making this its first-ever recorded sell on the ticker; no other institutional buyers clustered in the past 60 days to absorb the overhang. Bull case: if Mantle Ridge's operational agenda (cost cuts, banner rationalization) is now priced in and a new strategic buyer emerges above $119, the exit is noise; bear case: a near-complete activist departure with mixed 14/14/7 analyst consensus and no upcoming earnings catalyst removes the primary re-rating engine.

Where it could go — Activist near-full exit of this magnitude ($248M, 91% of direct shares) typically pressures the stock 5–15% over 30–60 days as the market reprices the loss of the activist premium; watch for a 13D/G amendment confirming Mantle Ridge's total position drop below 5%, and monitor whether a buyback acceleration or new 13D filer appears above $111 to signal a handoff.
