Data centers add growth, but margins still need proof
- Knife River is an aggregates-led construction materials company with 1.3 billion tons of owned reserves.
- Data center projects drove $18.5 million in additional Q2 2026 revenue, mainly in higher-margin aggregate sales.
- The contracting backlog is strong, but expected margins remain slightly lower than the prior year.
- The West segment showed new weakness due to a lack of public-agency work in Oregon and California.
- Management is using price increases and small acquisitions to push through cost and weather challenges.
Data centers help, but the West slows down
Knife River has a growing catalyst in data centers. The Q2 2026 results confirmed that data center projects added $18.5 million in revenue, mostly from higher-margin aggregate sales in North Dakota and Texas. This helps prove that the company can benefit from the technology boom by supplying the physical materials needed to build large facilities.
The bull case rests on this new demand and the company's pricing power. Knife River has successfully increased prices across its segments to fight cost pressures. Small acquisitions, like TexCrete, are also driving strong volume growth in key markets.
The bear case centers on margin pressure and regional weakness. The West segment saw lower contracting services revenue in Q2 2026 because of less public-agency work in Oregon and California. Furthermore, expected margins on the massive $1.2 billion backlog remain slightly lower than the prior year.
Finn's view watches the race between volume growth and margin compression. The company has strong revenue visibility, but execution on cost controls and a rebound in West segment bidding are needed to protect profit.
Rock first, roads second
Knife River starts with owned aggregates, meaning crushed stone, sand, and gravel. It has 1.3 billion tons of aggregate reserves, and about 35 percent of its aggregates are used inside the company for ready-mix concrete, asphalt, and contracting services. That internal use can lower costs and keep more profit in-house.
The company makes money in two connected ways. It sells materials like aggregates, ready-mix concrete, asphalt, and liquid asphalt. It also performs heavy-civil work such as paving, grading, site development, concrete construction, and bridges.
Location is a big part of the model. Rock is heavy and costly to move, so quarries near growing mid-sized markets can be valuable. Knife River operates in multiple states, with public projects providing stability against the swings of private markets.
The model can break when weather delays work, input costs jump, public funding slows, or acquired businesses do not fit. The company uses a strategy to trade lower volume for higher prices in some areas to protect margins.
What Knife River sells
Aggregates
Aggregates are crushed stone, sand, and gravel. They are the base input for roads, concrete, and asphalt, and they anchor the company's vertical integration.
Ready-mix concrete
Ready-mix concrete is sold into public and private construction. Acquisitions have boosted volumes in key markets.
Asphalt
Asphalt is used in paving and road projects. It benefits when contracting work and public agency work are active, but volumes can swing with weather and project timing.
Contracting services
This includes paving, grading, site development, concrete work, and bridges. It has strong backlog, but also an open margin question.
Liquid asphalt
The Energy Services segment produces and supplies liquid asphalt, mainly for asphalt road construction.
Where revenue comes from
Segment mix uses early 2026 segment revenue before corporate services and eliminations. West remains the largest segment, so weather or public funding changes there can move results.
What could go wrong
Lower-margin backlog
High impact · Medium oddsKnife River's backlog is at a record level, but the Q2 2026 filing says expected margins on backlog were slightly lower than the prior year. If that work converts at weak profit, revenue growth may not lift earnings enough.
Public funding and West weakness
High impact · Medium oddsThe West segment showed weakness in the second quarter of 2026 because of less public-agency work in Oregon and California. A lack of state or federal funding can hurt both revenue and margins.
Acquisition digestion
Medium impact · Medium oddsKnife River keeps using acquisitions to grow, including the recent TexCrete deal in Texas. These deals can add reserves and market share, but they also add payroll, overhead, systems work, and integration risk.
Weather and seasonality
Medium impact · High oddsWeather can disrupt operations. Rain, snow, and storms can delay both materials sales and contracting work, making the first quarter especially vulnerable and risking peak season delays.
In one breath
What does Knife River Corporation do?
Knife River sells construction materials like aggregates, ready-mix concrete, asphalt, and liquid asphalt. It also performs contracting work such as paving, grading, site development, and bridge construction.
Why does Knife River's backlog matter?
Backlog is contracted work that has not yet been finished. Knife River's backlog is strong, but the filing warns that expected margins are slightly lower than last year.
Is Knife River tied to government spending?
Yes. Public projects make up a large portion of contracting services revenue each year. That can be stabilizing, but it also creates risk if state or federal road funding slows.
What is the data center opportunity for Knife River?
Data center projects are adding demand, especially in the Central segment. In the second quarter of 2026, this work drove $18.5 million in additional aggregate materials revenue.
