Canadian National Railway (CNI) Q2 2026 earnings review
Growth Engine Restarts: Top-Line Surges 11% and Guidance Raised
Canadian National Railway (CN) delivered a decisive breakout quarter, shaking off a stagnant 2025 with an 11% YoY revenue jump to C$4,753 million. Volume (RTMs) accelerated 5%, propelled by double-digit growth in Grain and Petroleum segments. Management signaled strong confidence by raising full-year guidance, now targeting mid-to-high single-digit EPS growth and low single-digit volume expansion. However, the volume recovery came at a cost: Adjusted Operating Ratio (OR) deteriorated by 50 basis points to 62.2% as soaring fuel prices overshadowed record locomotive fuel efficiency.
🐂 Bull Case
Management confidently reversed their previous cautious stance, raising FY26 volume guidance from 'flattish' to 'low single-digit' growth, and EPS guidance to 'mid-to-high single-digit' growth.
Grain & Fertilizers surged 18% YoY and Petroleum & Chemicals jumped 16%. CN's exposure to natural resources and structural network advantages are paying massive dividends in the current macro environment.
🐻 Bear Case
Despite 11% revenue growth, the Adjusted Operating Ratio increased (worsened) by 50 bps to 62.2%. Rising fuel and labor costs are preventing top-line growth from fully flowing to the bottom line.
While most of the business is accelerating, Coal revenue was completely flat (0% YoY) and volumes contracted by 6%, creating a structural drag on the broader portfolio.
⚖️ Verdict: 🟢
Bullish. The aggressive upward revision to guidance, coupled with strong double-digit growth in key bulk segments and a 19% surge in Free Cash Flow, overshadows the slight margin compression caused by external fuel price volatility.
Key Themes
Grain and Energy Lead Revenue Acceleration
CN's top-line turnaround was fiercely driven by its bulk segments. Grain & Fertilizers revenue accelerated 18% YoY (RTMs up 11%), aided by strong Canadian and U.S. crops. Petroleum & Chemicals also surged 16% (RTMs up 11%). This proves CN's 'boots on the ground' commercial intensity and specialized network routing are successfully capturing market share.
Operating Leverage Fails to Materialize
A fundamental red flag: 11% revenue growth usually triggers aggressive margin expansion in the rail industry. Instead, CN's Adjusted Operating Ratio increased from 61.7% to 62.2%. Operating expenses ballooned 13% YoY, driven heavily by a 60% surge in fuel costs. Management needs to demonstrate they can convert this newfound volume into pure profit rather than just covering rising costs.
Strategic MOU with Union Pacific
In a defensive and offensive masterstroke amidst the proposed Union Pacific/Norfolk Southern merger, CN announced a Memorandum of Understanding with UP. CN will secure new rights over UP's network for moves between Canada and Mexico, giving CN unprecedented north-south connectivity and effectively neutralizing competitive threats from industry consolidation.
Record Fuel Efficiency via AI and Tech Integration
Despite higher fuel prices hurting the bottom line, CN's technological execution is shining. The company achieved a record fuel efficiency of 0.836 US gallons per 1,000 GTMs (a 3% improvement YoY). Management's continued integration of artificial intelligence for network fluidity and the pursuit of new locomotive propulsion technology are effectively decoupling volume growth from proportional fuel consumption.
Coal and Metals Acting as Structural Laggards
Not all segments participated in the Q2 boom. Coal revenue was absolutely flat (0% YoY) with RTMs shrinking 6%, while Metals & Minerals lagged the company average at just 6% revenue growth and negative 1% volume growth. These underperforming segments require careful monitoring as they drag down overall network yield.
Data Contradiction: Fuel Efficiency vs Fuel Expense
Management touted a 3% improvement in operational fuel efficiency (0.836 gallons per 1k GTMs). However, total fuel expense skyrocketed 60% YoY to C$659 million. While CN operates more efficiently per mile, the absolute cost of energy remains a volatile and largely uncontrollable threat to the bottom line.
Upgraded Macroeconomic Backing
Management explicitly upgraded their macro view, shifting from defensive to offensive. They assume 2026/2027 grain crops will hit their 5-year averages and noted sustained business momentum, signaling that the 'flattish' industrial stagnation observed in late 2025 has formally broken.
Other KPIs
Accelerating. Up 19% YoY from C$1,548 million in H1 2025. This robust cash generation easily funded C$454 million in Q2 share repurchases and underpins the company's commitment to returning capital to shareholders while maintaining a 2.61x debt-to-EBITDA ratio.
Reversing the slight Q1 contraction (-3%), adjusted EPS grew 11% YoY. Excluding a C$17 million advisory cost related to rail consolidation matters, the company demonstrated solid fundamental earnings power.
Decelerating. Down from C$1,324 million in H1 2025. This disciplined reduction in CapEx is the primary driver behind the 19% acceleration in Free Cash Flow.
Guidance
Accelerating. Upgraded from the previous assumption of 'flattish' growth, reflecting stronger-than-expected commercial wins and a robust agricultural outlook.
Accelerating. Upgraded from the previous expectation of EPS 'slightly exceeding RTM growth'. This signals management's confidence in unlocking operating leverage in the second half of the year.
Stable. The company is maintaining its strict capital discipline, reducing spend compared to 2025 to maximize free cash flow conversion.
Key Questions
Path to Operating Leverage
With 11% top-line growth, the Operating Ratio worsened by 50 bps. Beyond fuel price volatility, what specific operational levers must be pulled in H2 to convert 'low single-digit' volume growth into 'mid-to-high single-digit' EPS growth?
Union Pacific MOU Mechanics
Regarding the new routing rights between Canada and Mexico via Union Pacific, when will these rights begin to generate material revenue, and what capital investments are required to facilitate this corridor?
Coal and Metals Weakness
Coal volumes fell 6% and Metals grew slower than the network average. Do you view this as a permanent structural shift in your bulk mix, and how are you reallocating assets away from these lagging segments?
