Knife River (KNF) is down about 4.6% to $84.75 as investors react to a negative analyst catalyst: Wells Fargo downgraded the stock to Equal Weight from Overweight, raising its price target to $81 but arguing the valuation looks “full.” The note also highlighted concerns tied to Oregon—described as roughly 23% of company sales—and warned that the Sept. 30 expiration of the IIJA (Infrastructure Investment and Jobs Act) is a risk factor for public-infrastructure momentum.

A valuation-driven downgrade can pressure shares quickly when a stock has been priced for strong execution, because it narrows the margin for error even if operations remain solid. The IIJA reference adds a macro overhang for aggregates and construction materials names tied to public work, raising the question of whether project timing, bidding, and state/local funding flows stay as supportive into late 2026 as investors have assumed.

Knife River entered 2026 pointing to momentum from record year-end backlog of about $1 billion and issued full-year 2026 guidance of $3.3–$3.5 billion revenue and $520–$560 million adjusted EBITDA, assuming normal conditions. Today’s move reflects that the market can still re-rate the stock lower on valuation and execution/geography-specific concerns even with constructive headline guidance and backlog.
