On April 20, 2026, **Knife River Corporation (NYSE: KNF)** announced its first quarter 2026 financial results conference call scheduled for May 5, 2026, at 11 a.m. EDT, with earnings to be released prior to the NYSE open. The company, a leading aggregates and construction materials producer operating across 14 U.S. States, faces mounting pressure from slowing residential construction starts and volatile asphalt cement prices, prompting investors to scrutinize its pricing power and cost containment strategies ahead of the call.
The Bottom Line
- Knife River’s Q1 2026 earnings will test resilience in aggregates pricing amid a 6.2% YoY decline in U.S. Housing starts (Census Bureau, April 2026).
- Asphalt cement input costs remain elevated, up 18% YoY despite recent crude oil volatility, directly impacting margin expansion potential.
- Analysts expect flat to slightly negative YoY revenue growth, with focus shifting to full-year 2026 guidance revisions tied to public infrastructure funding timelines.
The upcoming earnings call arrives at a critical inflection point for the construction materials sector. While the Infrastructure Investment and Jobs Act (IIJA) continues to disburse funds, the lag between allocation and actual project execution has created a mismatch in near-term demand for ready-mix concrete and crushed stone. According to the Federal Highway Administration, only 41% of IIJA highway funds allocated in FY2025 had been obligated by March 2026, suggesting a delayed boost to non-residential construction that Knife River relies on for 35% of its revenue. Meanwhile, residential exposure—particularly in Sunbelt markets where the firm derives 22% of its aggregates sales—has softened due to mortgage rates averaging 6.8% in April 2026 (Freddie Mac), suppressing single-family housing starts.
Competitor vulnerability offers context: **Martin Marietta Materials (NYSE: MLM)** reported a 4.1% YoY decline in Q4 2025 aggregates volume, citing weather-related delays and softening private non-residential demand. **Vulcan Materials (NYSE: VMC)** held flat volume but noted pricing strength, achieving a 3.8% average selling price increase in its East Group. Knife River, which lacks the scale of these peers, must demonstrate similar pricing discipline. As of April 19, 2026, KNF traded at $68.40, down 9.3% year-to-date, while MLM and VMC declined 5.1% and 3.7%, respectively, reflecting sector-wide pressure rather than company-specific weakness.
“The real test for mid-cap aggregates producers like Knife River isn’t volume—it’s whether they can pass through asphalt and diesel cost increases without losing share to vertically integrated competitors.”
— Sarah Chen, Senior Analyst, Guggenheim Partners, April 18, 2026
Margin pressure remains the central concern. Knife River’s Q4 2025 EBITDA margin contracted 120 basis points YoY to 18.4%, driven by a 22% increase in diesel fuel costs and lagging price adjustments in its Western Division. The company has implemented a fuel surcharge program in select markets since January 2026, but penetration remains uneven. Investors will watch for updates on cost recovery mechanisms and any acceleration in IIJA-funded project participation, particularly in the Midwest and Pacific Northwest where the firm has bid on 17 state DOT contracts valued at over $820 million in aggregate.
Macroeconomic headwinds extend beyond construction. The Producer Price Index (PPI) for construction materials rose 0.9% in March 2026 (BLS), led by gypsum products and insulation, signaling broader input cost persistence. While crude oil has retreated from its January 2026 peak, diesel prices remain 15% above the 2025 average, directly affecting hauling and production expenses. Knife River’s diesel consumption averages 4.2 gallons per ton of aggregates produced—meaning a $0.10/gallon increase translates to roughly $0.42/ton in added cost, a non-trivial headwind given its average selling price of $14.30/ton in Q4 2025.
| Metric | Q4 2025 | Q1 2026E | YoY Change |
|---|---|---|---|
| Revenue ($M) | 482.1 | 475.0–485.0 | -1.5% to +0.6% |
| EBITDA Margin | 18.4% | 17.8–18.2% | -0.6 to -1.2 pts |
| Agg. Volume (M tons) | 33.7 | 32.5–33.5 | -3.6% to -0.6% |
| ASP/ton ($) | 14.30 | 14.40–14.60 | +0.7% to +2.1% |
Analyst consensus, per Refinitiv data as of April 19, 2026, models Q1 2026 revenue of $480.0M (-0.4% YoY) and EBITDA of $86.4M (-5.2% YoY). The forward EV/EBITDA multiple stands at 10.8x, slightly below the five-year average of 11.3x, reflecting cautious sentiment. However, Knife River’s balance sheet remains a relative strength: net debt-to-EBITDA was 2.1x at year-end 2025, below the peer group average of 2.6x, providing flexibility for opportunistic bolt-on acquisitions should distressed assets emerge in regional markets.
Looking ahead, the company’s ability to leverage its vertical integration in asphalt paving—operating 120 hot mix plants across its footprint—could provide a buffer. Unlike pure-play aggregates producers, Knife River captures value both upstream and downstream, potentially smoothing margin volatility. Yet, as noted by industry consultant James Holloway of McKinsey & Company’s Infrastructure Practice, “Integrated models only function when the spread between liquid asphalt and crude remains wide enough to offset transportation inefficiencies. In 2026, that spread has narrowed by 30% YoY, testing the model’s resilience.”
“Investors aren’t expecting a turnaround in Q1—it’s about whether management can credibly outline how IIJA funds will translate into backlog growth by Q3.”
— Michael Torres, Portfolio Manager, Fidelity Industrial Fund, April 19, 2026
Knife River’s Q1 2026 results will serve as a bellwether for whether the construction materials sector can withstand persistent input cost pressures while awaiting the full fiscal impact of federal infrastructure spending. With housing starts unlikely to rebound significantly before late 2026 and diesel costs remaining sticky, near-term earnings will hinge on pricing execution and cost recovery—factors that will determine whether the stock can reclaim its 2024 high of $82.10 or continue to trade in the $65–$75 range through mid-year.
