RBC Capital Downgrades Knife River to Sector Perform Due to Costs

RBC Capital has downgraded Knife River Corp. (KNF) from Outperform to Sector Perform. The firm cited rising input costs and project delays that threaten company margins. RBC also reduced its price target for the stock from $103.00 to $58.00, representing a decrease of nearly 44%.

"Input cost inflation remains a primary headwind for the U.S. heavyside sector, which may negatively impact Knife River's contract volumes toward the end of the construction season," said Anthony Codling, analyst at RBC Capital, in a note to investors.

Operational Headwinds and Margin Pressure

Knife River is navigating operational challenges that forced a downward revision of its financial expectations. The company now projects that its second-half 2026 contracting services margins will land between 9% and 10%.

Management attributed these tighter margins to two factors:

• Rising Fuel Costs: Increases in diesel prices have pushed operating expenses higher, impacting the profitability of ongoing construction projects.
• Project Slippage: Delays in key infrastructure work, specifically the Hawaii P-209 project, have pushed that work into the 2027 fiscal calendar.

Broader Inflationary Context

These company-specific pressures occur while the broader U.S. economy experiences elevated price levels. According to FRED economic data, the Consumer Price Index (CPI) for all urban consumers reached 336.3 as of September 2026. This index serves as a benchmark for the environment that construction firms navigate when bidding on long-term contracts, where fixed pricing often prevents the immediate pass-through of rising material and energy costs.

What Is at Stake

The downgrade highlights the vulnerability of construction-related stocks to the current macro-economic environment. As input costs remain elevated, firms like Knife River face the task of maintaining competitive bids to capture market share while ensuring that projects remain profitable despite fluctuating expenses for fuel and raw materials. Investors are watching to see if the company can stabilize its margins as it moves into the 2027 construction season.
